Observation of a Gamma-Ray Pulse at Ground Level Produced by an Atmospheric Lightning Discharge in SŃo Josķ dos Campos, SP, Brazil
NASA Astrophysics Data System (ADS)
Alves, Mauro; Spjeldvik, Walther; Gusev, Anatoly; Martin, Inacio; Gomes, Marcelo
We have used a gamma scintillator (Ludlum, USA; Model 44-20) consisting of NaI(Tl) crystal (diameter, 7.6 cm; length, 7.6 cm) optically coupled to a photomultiplier tube (diameter, 7.6 cm) to measure local background gamma radiation in the energy range of 60 keV to 2 MeV. Data are collected one-minute intervals. The scintillator was housed in an air-conditioned room and measurements have been made almost continuously for more than three years at the same location in SŃo Josķ dos Campos, SP, Brazil (23░ 12Æ 45ö S, 45░ 52Æ 0 W). During a summer thunderstorm that occurred on January 13, 2014 at 18:44 h (local time) a lightning stroke a nearby lightning rod installed in the same building and was observed by one of us (I.M.M.). Simultaneously to the occurrence of the lightning strike, the scintillator recorded a pulse of gamma-rays which lasted for only one minute (count integration time) and whose amplitude was approximately twice as large as that of the normal background count. Data from the World Wide Lightning Location Network (WWLLN) confirms that at the time of the pulse there was intense electrical activity in the area. Since spurious signals, malfunctioning equipment or electromagnetic transients were not responsible for the pulse we are led to believe that we recorded a gamma-ray pulse produced by the lightning discharge.

Sand fly fauna (Diptera: Psychodidae) from the Goytacazes National Forest and surrounding areas of southeastern Brazil.
das Virgens, Thieres Marassati; Rezende, Helder Ricas; de Souza Pinto, Israel; Falqueto, AloĒsio
Most studies of the sand fly fauna in southeastern Brazil are conducted in the peridomiciliary environment of leishmaniasis endemic regions. Therefore, to increase the knowledge about diversity and richness of sand fly conservation areas, we describe here the sand fly fauna from the National Forest of Goytacazes (NFG), state of EspĒrito Santo, Brazil, and its surroundings areas. We also used sand fly fauna records from eight conservations units within the state of EspĒrito Santo to understand the similarity and relationships among them. The sand flies were simultaneously collected from June, 2008 to May, 2009 in two different environments: a preserved environment represented by the NFG and a modified environment represented by a peridomicile. To establish the similarity among the conservation units, we used a method very similar to parsimony analysis of endemism. We collected 2,466 sand fly specimens belonging to 13 species. Pressatia choti and Nyssomyia intermedia were the most abundant sand fly species. Ny. intermedia is a known vector of Leishmania braziliensis and epidemiological surveillance must be conducted in the area. We discuss aspects regarding the diversity of sand flies as well as the risk of transmission of Leishmania parasites in the area. We also provide for the first time a hypothesis of similarity relationships among conservation units within the state of EspĒrito Santo. PMID:26047181

Circumscribing campo rupestre - megadiverse Brazilian rocky montane savanas.
Alves, R J V; Silva, N G; Oliveira, J A; Medeiros, D
Currently campo rupestre (CR) is a name accepted and used internationally by botanists, zoologists, and other naturalists, usually applied to a very specific ecosystem, despite the lack of a consensual published circumscription. We present a tentative geographic circumscription of the term, combining data on climate, geology, geomorphology, soil, flora, fauna and vegetation. The circumscription of campo rupestre proposed herein is based on the following premises: (1) the classification of vegetation is not an exact science, and it is difficult to attain a high degree of consensus to the circumscription of vegetation names; (2) despite this, vegetation classification is useful for conservation and management. It is thus desirable to circumscribe vegetation types with the greatest attainable precision; (3) there is a need to preserve all montane and rocky vegetation types, regardless of classification, biome, etc; (4) the CRs are formed by a complex mosaic of vegetation types including rock-dwelling, psammophilous, aquatic, epiphytic, and penumbral plant communities. Campos rupestres stricto sensu are a Neotropical, azonal vegetation complex endemic to Brazil, forming a mosaic of rocky mountaintop "archipelagos" inserted within a matrix of zonal vegetation, mainly in the Cerrado and Caatinga provinces of the Brazilian Shield (southeastern, northeastern and central-western regions), occurring mainly above 900 m asl. up to altitudes exceeding 2000 m, having measured annual precipitation between 800 and 1500 mm, and an arid season of two to five months.

Helping enhances productivity in campo flicker ( Colaptes campestris) cooperative groups
NASA Astrophysics Data System (ADS)
Dias, Raphael Igor; Webster, Michael S.; Macedo, Regina H.
Reproductive adults in many bird species are assisted by non-breeding auxiliary helpers at the nest, yet the impact of auxiliaries on reproduction is variable and not always obvious. In this study, we tested Hamilton's rule and evaluated the effect of auxiliaries on productivity in the facultative cooperative breeder campo flicker ( Colaptes campestris campestris). Campo flickers have a variable mating system, with some groups having auxiliaries and others lacking them (i.e., unassisted pairs). Most auxiliaries are closely related to the breeding pair (primary auxiliaries), but some auxiliaries (secondary auxiliaries) are unrelated females that joined established groups. We found no effect of breeder quality (body condition) or territory quality (food availability) on group productivity, but the presence of auxiliaries increased the number of fledglings produced relative to unassisted pairs. Nonetheless, the indirect benefit of helping was small and did not outweigh the costs of delayed breeding and so seemed insufficient to explain the evolution of cooperative breeding in campo flickers. We concluded that some ecological constraints must limit dispersal or independent breeding, making staying in the group a "best-of-a-bad-job" situation for auxiliaries.

A model for petroleum biodegradation in the Campos Basin, Brazil
Cerqueira, J.R.; Ferreira, J.C. [Petrobras Research Center, Rio de Janeior (Brazil)
The Campos Basin covers about 100,000 km{sup 2} along Brazil`s southeastern passive margin and is the most productive offshore Brazilian basin. Geochemical analyses of oils and formation waters indicate that the oils were deeply biodegraded during the first events of migration due to many cycles of meteoric water influx into the basin caused by sea level variations. Since the source rocks are still generating hydrocarbons, some reservoirs present a mixture of previously trapped biodegraded oil and nonbiodegraded oil that migrated to the same reservoirs after the end of the meteoric water infiltration event.

Subsidence history and tectonic evolution of Campos basin, offshore Brazil
Mohriak, W.U.; Karner, G.D.; Dewey, J.F.
The tectonic component of subsidence in the Campos basin reflects different stages of crustal reequilibration subsequent to the stretching that preceded the breakup of Pangea. Concomitant with rifting in the South Atlantic, Neocomian lacustrine rocks, with associated widespread mafic volcanism, were deposited on a vary rapidly subsiding crust. The proto-oceanic stage (Aptian) is marked by a sequence of evaporitic rocks whose originally greater sedimentary thickness is indicated by residual evaporitic layers with abundant salt flow features. An open marine environment begins with thick Albian/Cenomanian limestones that grade upward and basinward into shales. This section, with halokinetic features and listric detached faulting sloping out on salt, is characterized by an increased sedimentation rate. The marine Upper Cretaceous to Recent clastic section, associated with the more quiescent phase of thermal subsidence, is characterized by drastic changes in sedimentation rate. Stratigraphic modeling of the sedimentary facies suggests a flexurally controlled loading mechanism (regional compensation) with a temporally and spatially variable rigidity. Locally, the subsidence in the rift-phase fault-bounded blocks shows no correspondence with the overall thermal subsidence, implying that the crust was not effectively thinned by simple, vertically balanced stretching. Deep reflection seismic sections show a general correspondence between sedimentary isopachs and Moho topography, which broadly compensates for the observed subsidence. However, even the Moho is locally affected by crustal-scale master faults that apparently are also controlling the movement mechanisms during the rift-phase faulting.
Energy and Mass Balance At Gran Campo Nevado, Patagonia, Chile
NASA Astrophysics Data System (ADS)
Schneider, C.; Kilian, R.; Casassa, G.
The Gran Campo Nevado (GCN) Ice Cap on Peninsula Mu±oz Gamero, Chile, is lo- cated in the southernmost part of the Patagonian Andes at 53S. It comprises an ice cap and numerous outlet glaciers which mostly end in proglacial lakes at sea level. The total ice covered area sums up to approximately 250 km2. GCN forms the only major ice body between the Southern Patagonian Icefield and the Street of Magallan. Its almost unique location in the zone of the all-year westerlies makes it a region of key interest in terms of glacier and climate change studies of the westwind zone of the Southern Hemisphere. Mean annual temperature of approximately +5C at sea level and high precipitation of about 8.000 mm per year lead to an extreme turn-over of ice mass from the accumulation area of the GCN Ice Cap to the ablation areas of the outlet glaciers. Since October 1999 an automated weather station (AWS) is run continuously in the area at Bahia Bahamondes for monitoring climate parameters. From February to April 2000 an additional AWS was operated on Glaciar Lengua a small outlet glacier of GCN to the north-west. Ablation has been measured at stakes during the same pe- riod. The aim of this study, was to obtain point energy and mass balance on Glaciar Lengua. The work was conducted as part of the international and interdisciplinary working group SGran Campo NevadoT and supported by the German Research Foun- & cedil;dation (DFG). Energy balance was calculated using the bulk approach formulas and calibrated to the measured ablation. It turns out, that sensible heat transfer is the major contribution to the energy balance. Since high cloud cover rates prevail, air tempera- ture is the key factor for the energy balance of the glacier. Despite high rain fall rates, energy input from rain fall is of only minor importance to the overall energy balance. From the energy balance computed, it was possible to derive summer-time degree-day factors for Glaciar Lengua. With data from the nearby AWS at Bahia Bahamondes we computed summer ablation for the summer seasons of 1999/2000 and 2000/2001. Ablation at 45o m a.s.l. sums up to about 7 m in 1999/2000 and to 5.5 m in 2000/2001. This is in excellent accordance (+/-2%) with measurements at ablation stakes that have been drilled into the glacier on its ablation area. Surface velocity measured from the displacement of the ablation stakes is estimated to 62 m per year. A RADAR survey with ice penetrating RADAR conducted on the ablation area of Glaciar Lengua during the austral summer 2000/2001 reveals glacier depths between 120 m and 200 m ap- 1 proximately. The data sampled will allow to set up a model for mass flow and ablation at a cross-section of Glaciar Lengua at 450 m a.s.l. Glaciar Lengua has no accumu- lation area itself but obtains all of its ice mass through icefall from the heights of the GCN Ice Cap. Therefore, this model will be of fundamental importance to understand the glacial regime of the entire ice cap. 2
The Marlin and Albacora giant fields, Campos Basin, offshore Brazil
De Souza, J.M.; Scarton, J.C.; Candido, A.; Cora, C.A.G. (Petrobras, Rio de Janeiro (Brazil))
The Albacore and Marlim giant fields are located in the province of Campos basin, about 110 km (68 mi) offshore Cape Sao Tome, in water depths ranging from 200 m (656 ft) to 2,000 m (6562 ft). The Albacora field was discovered in September 1984 by the wildcat 1-RJS-297, drilled in 293 m (961 ft) of water. Subsequently, the wildcats 1-RJS-305 and 1-RJS-342 extended the field limits to deeper waters. The Albacora field is approximately 235 km{sup 2} (90 mi{sup 2}) in area, with an estimated volume of 4.5 billion bbl of oil in place. The Marlim field was discovered in February 1985 by the wildcat 1-RJS-219A, in a water depth of 853 m (2,800 ft). The Marlim field area is about 152 km{sup 2} (58 mi{sup 2}), and the latest estimate of oil in place is about 8.2 billion bbl. The Marlim complex encompasses Marlim field itself and the surrounding proved and potential areas known as East-of-, West-of-, and South-of-Marlim, respectively. The current estimated volume of oil in place in the Marlim complex is close to 13.9 billion bbl, with a total surface of about 350 km{sup 2} (135 mi{sup 2}). Oil production in the Albacora field comes from Lower Cretaceous (Albian) and Tertiary (Eocene, Oligocene, and Miocene) turbidite reservoirs. Oligocene turbidite sandstones are the potential reservoirs in the Marlim field. These deposits are genetically associated with sea level variations and are mainly composed of massive sandstones and, subordinately, of contourites. Both fields are structurally and stratigraphically controlled accumulations. Hydrocarbons are trapped in anticlines and/or faulted blocks associated with salt tectonics. Stratigraphic contributions result from sandstone bodies pinching out against shales and marls. The development of these fields has been supported by three-dimensional seismic data. The Albacora field is being gradually put on stream from shallower to deeper waters.

Vascular plant community composition from the campos rupestres of the Itacolomi State Park, Brazil
Leyh, Werner; Miazaki, Angela S.; Meira-Neto, JoŃo A.A.
Abstract Campos rupestres are rare and endangered ecosystems that accommodate a species-rich flora with a high degree of endemism. Here, we make available a dataset from phytosociological surveys carried out in the Itacolomi State Park, Minas Gerais, southeastern Brazil. All species in a total of 30 plots of 10 x 10 m from two study sites were sampled. Their cardinality, a combination of cover and abundance, was estimated. Altogether, we registered occurrences from 161 different taxa from 114 genera and 47 families. The families with the most species were Poaceae and Asteraceae, followed by Cyperaceae. Abiotic descriptions, including soil properties such as type, acidity, nutrient or aluminum availability, cation exchange capacity, and saturation of bases, as well as the percentage of rocky outcrops and the mean inclination for each plot, are given. This dataset provides unique insights into the campo rupestre vegetation, its specific environment and the distribution of its diversity. PMID:25829858

Infrared inspection applied to offshore platforms: Petrobras experience at Campos Basin
NASA Astrophysics Data System (ADS)
Verdini, Edson A.; Veratti, Attilio B.
Bacia de Campos (Rio de Janeiro - Brazil) is one of the biggest offshore petroleum fields in the world today. In June 2001, Bacia de Campos, having more than 490 oil wells, 34 offshore platforms and 7 modified ships in operation, reached 1,3 million barrels/day. If compared to OPEP countries only nine of them got an average production higher than 1 million barrels/day in 2000, which means it can be placed on the 10th position in the rank of oil producers. In this context this work aims not only to show the results achieved within the introduction of thermographic inspections in offshore oil production (platforms and ships), but also the financial results (ROI - Return of Investment) considering the use of this particular technique. Bacia de Campos got a ROI around 7 million dollars in the last 4 years, which means a hundred times higher than the total cost of thermographic services in the same period. As far as we know this is one of the best results already reported in the world. We also present the methodology applied to analyze thermal anomalies in electrical components and data management software, including advanced Digital Reports sent via Internet.

Scorzelli, R. B.; Michel-Levy, M. Christophe; Gilabert, E.; Lavielle, B.; Souza Azevedo, I.; Vieira, V. W.; Costa, T. V. V.; Araujo, M. A. B.
The Campos Sales meteorite fell close to the town of Campos Sales, in the northeastern Brazilian state of Ceara (72' deg S; 4010' deg W), on 31 January 1991, at 10:00 PM (local time). Several fragments were recovered from an area estimated to be 3 km ? 1 km. The stone is an ordinary chondrite, L5 ( Fa25.0 and Fs21.6 ), lightly shocked, S1. Metal phases present are kamacite, tetrataenite and antitaenite. Noble gases He, Ne, Ar, Kr and Xe have been analyzed in 2 bulk samples of Campos Sales. All exposure ages based on determination of cosmogenic 3He, 21Ne, 38Ar, 83Kr, 126Xe abundances and on cosmogenic 81Kr/83Kr ratio agree well, suggesting no gas loss during cosmic-ray exposure. The cosmic-ray exposure age is 23.3 +- 1.0 Ma, which falls in the range observed for L5 chondrites (20-30 Ma). The gas-retention ages indicate He loss that must have occurred prior to or during ejection from the L-chondrite parent body.

The Study of Natural Radiation Distribution in Soil of Sao Bernardo do Campo
Matsumoto, M. M.; Silveira, M. A. G. [Centro Universitrio da FEI, Sao Bernardo do Campo, Sao Paulo (Brazil); Medina, N. H.; Umisedo, N. K. [Instituto de Fisica da Universidade de Sao Paulo, Sao Paulo (Brazil)
We have studied the distribution of natural radioactivity in the soil of five sites of the city Sao Bernardo do Campo, Sao Paulo, Brazil. The main contribution of the radiation dose is due to the isotope {sup 40}K, with smaller contributions from the elements of the series of {sup 238}U and {sup 232}Th. The results indicate the dose in all of the studied areas is around the average international dose due to external exposure to gamma rays (0.48 mSv/yr) proceeding from natural terrestrial elements.
[The archeology of slavery on Jesuit fazendas: first research notes].
Symanski, LuĒs Clßudio P; Gomes, Flßvio
These preliminary research notes present theoretical and methodological questions regarding a recently inaugurated investigation in historical archeology that intends to analyze daily life under slavery, demographic regimes, cultural practices, and so on. A survey of archeological sites on former 'senzalas' (slave quarters) and slave-owning fazendas in the ParaĒba Valley and northern part of the state of Rio de Janeiro is currently in progress. With the cooperation of historians, archeologists, and anthropologists, records of the material culture of slave populations, which originally comprised indigenes and later Africans, are being located at excavations underway on the fazenda that is part of the Jesuit school in Campos dos Goytacazes, Rio de Janeiro, first run by the clergy and later by members of the laity in the seventeenth, eighteenth, and nineteenth centuries.

Self-regulating the effortful "social dos".
Cortes, Kassandra; Kammrath, Lara K; Scholer, Abigail A; Peetz, Johanna
In the current research, we explored differences in the self-regulation of the personal dos (i.e., engaging in active and effortful behaviors that benefit the self) and in the self-regulation of the social dos (engaging in those same effortful behaviors to benefit someone else). In 6 studies, we examined whether the same trait self-control abilities that predict task persistence on personal dos would also predict task persistence on social dos. That is, would the same behavior, such as persisting through a tedious and attentionally demanding task, show different associations with trait self-control when it is framed as benefitting the self versus someone else? In Studies 1-3, we directly compared the personal and social dos and found that trait self-control predicted self-reported and behavioral personal dos but not social dos, even when the behaviors were identical and when the incentives were matched. Instead, trait agreeableness--a trait linked to successful self-regulation within the social domain--predicted the social dos. Trait self-control did not predict the social dos even when task difficulty increased (Study 4), but it did predict the social don'ts, consistent with past research (Studies 5-6). The current studies provide support for the importance of distinguishing different domains of self-regulated behaviors and suggest that social dos can be successfully performed through routes other than traditional self-control abilities.

Piovesan, Enelise Katia; Nicolaidis, Demķtrio Dias; Fauth, Gerson; Viviers, Marta Claudia
The Lower and Upper Cretaceous deposits from the Brazilian marginal basins present a rich and diversified fauna of ostracodes in continental, marine and mixohaline paleoenvironments. While the Cretaceous ostracodes from the northeastern region have already been the subject of many taxonomic and biostratigraphical studies, data from the southeastern basins are still scarce and restricted to the record of a few species. The present study represents a comprehensive contribution to the systematic knowledge of the Aptian-Santonian ostracodes from the Brazilian southeastern marginal basins. A total of 1045 cutting samples were analyzed from 10 wells drilled offshore in Santos, Campos and EspĒrito Santo basins. Thirty-eight ostracode taxa were recorded from different depositional environments, including the following six new species: Amphicytherura fragilis sp. nov., Brachycythere multidifferentis sp. nov., Fossocytheridea ballentae sp. nov., Fossocytheridea elegans sp. nov., Nigeroloxoconcha itanhaensis sp. nov. and Paracypris eniotmetos sp. nov.
Time, Weather and Empires: The Campos Rodrigues Observatory in Lourenńo Marques, Mozambique (1905-1930).
Raposo, Pedro M P
In 1905 the Campos Rodrigues Observatory (CRO) was founded in Lourenńo Marques (nowadays Maputo), the capital of Mozambique, by then part of the Portuguese overseas empire. In this paper the inception and early history of the CRO are analysed in the broader context of the interwoven history of the Portuguese and British empires in Africa, and specifically with respect to the scientific relations between Mozambique and South Africa. The equipment, personnel, practices and networks involved in the inception and early development of the CRO are brought into focus in order to illustrate the problems and strategies that shaped the establishment and functioning of this observatory, which was conceived essentially as a symbol of imperial stamina and colonial prowess. It is suggested that by providing a focal point for the development of scientific relations between Mozambique and South Africa, the CRO served both Portuguese ambitions for recognition as an imperial power and the emergence of South African nationalism.

Slope sand deposits have accumulated from at least the Neogene to the Present on the southeastern Brazilian continental margin (Campos Basin area). This region shows sand accumulations concentrated on the upper portion and on the base of the continental slope with a middle to lower slope bypass zone. A synthesis of preliminary results, supported by recent cores, high-resolution geophysical surveys, geotechnical investigations and environmental research, is presented and permits a prelitrunary analysis of the sedimentological mechanisms operational in this area. These point toward a temporal and spatial multiscale set of phenomena responsible for sand deposits. At any sea-level stand these deposits are dependent on: (1) a suitable sediment source; (2) offshelf transport mechanisms; (3) a morphostructural and hydrodynamic context responsible for the deposition of these sands in the upper portion of continental slopes. The proposed scenario of depositional processes concerns: (1) a set of hydrological processes such as surface currents and counter-currents, waves, tides and eddies with sufficient energy to form submarine sand dune fields at the outer shelf; (2) the offshelf export of this sediment under a combined action of spillover, internal waves, eddies 'seafloor polishing effect' and gravity processes (turbidity currents); and (3) the slope sand deposits and their distribution controlled by the action of contour currents, mass movements and the morphological context, such as canyons, gullies or scarps.
Variation of surface ozone in Campo Grande, Brazil: meteorological effect analysis and prediction.
Pires, J C M; Souza, A; PavŃo, H G; Martins, F G
The effect of meteorological variables on surface ozone (O3) concentrations was analysed based on temporal variation of linear correlation and artificial neural network (ANN) models defined by genetic algorithms (GAs). ANN models were also used to predict the daily average concentration of this air pollutant in Campo Grande, Brazil. Three methodologies were applied using GAs, two of them considering threshold models. In these models, the variables selected to define different regimes were daily average O3 concentration, relative humidity and solar radiation. The threshold model that considers two O3 regimes was the one that correctly describes the effect of important meteorological variables in O3 behaviour, presenting also a good predictive performance. Solar radiation, relative humidity and rainfall were considered significant for both O3 regimes; however, wind speed (dispersion effect) was only significant for high concentrations. According to this model, high O3 concentrations corresponded to high solar radiation, low relative humidity and wind speed. This model showed to be a powerful tool to interpret the O3 behaviour, being useful to define policy strategies for human health protection regarding air pollution. PMID:24854500
Pollination of Cambessedesia wurdackii in Brazilian Campo Rupestre Vegetation, with Special Reference to Crepuscular Bees
Franco, Emanuella Lopes; Gimenes, Miriam
Cambessedesia wurdackii Martins (Myrtales: Melastomataceae) is presumably endemic to the Chapada Diamantina, Bahia State, Brazil. A majority of the species of this family are pollinated by diurnal bees that buzz the floral anthers to collect pollen. The present work examined the interactions between C. wurdackii and visiting bees, focusing on temporal, morphological, and behavioral features, especially in regards to the crepuscular bees Megalopta sodalis (Vachal) (Hymenoptera: Halictidae) and Ptiloglossa off. dubia Moure (Hymenoptera: Colletidae). The study was undertaken in an area of campo rupestre montane savanna vegetation located in the Chapada Diamantina Mountains of Bahia State, Brazil, between August/2007 and July/2008. Flowering in C. wurdackii occurred from April through July, with a peak in May. A total of 592 visits by diurnal and crepuscular bees to the flowers of C. wurdackii were recorded, with a majority of the visits made by M. sodalis and P. dubia (92%) near sunrise and sunset. The anthers of C. wurdackii are arranged in two tiers, which favors cross pollination. The morphological, temporal and behavioral characteristics of M. sodalis and P. dubia indicated that they were potential pollinators of C. wurdackii, in spite of the fact that the colorful and showy flowers of this species are more typical of a diurnal melittophilous pollination syndrome.

Herein, we report tick species found on wild and domestic animals and in the environment during a one-year sampling period at the Brazilian Farming Research Company beef cattle unit (Embrapa Beef Cattle), which is located within the urban area of Campo Grande, Mato Grosso do Sul, Brazil. From 55 wild hosts including six different species (Nasua nasua, Cebus spp., Cerdocyon thous, Myrmecophaga tridactyla, Tamandua tetradactyla and Dasyprocta aguti), 323 ticks were collected. Amblyomma ovale ticks were found solely on coatis, and Amblyomma nodosum was identified solely on anteaters. No ticks were found on capuchin monkeys. However, Amblyomma cajennense was found on all parasitized host species with the exception of capuchin monkeys. Giant anteaters displayed the highest infestation abundance, with a mean of 53 ticks?animal. Environmental sampling yielded 166 adult A. cajennense ticks. The tick species found on domestic animals (Rhipicephalus (Boophilus) microplus, R. sanguineus, Dermacentor nitens and A. cajennense) were those typically found on these hosts in Brazil. The most prevalent tick species, A. cajennense, was found on both wild and domestic animals and was also prevalent in the environment. Thus, this tick species is the primary vector that allows pathogens to bridge wild and domestic animals in the Cerrado. PMID:24252958
Interpretation of Topographic Data from "SHAPE from SHADING" Method, Application in VILLAGARC═A de Campos Castle
NASA Astrophysics Data System (ADS)
GarcĒa Fernßndez, J.
Generating digital products allowing the assessment and interpretation of Cultural Heritage is a key task in conservation processes. Thus a variety of (Shape from X) methods have been developed through photogrammetry with that aim in mind, which in the digital era widen their scope on account of independence of physical resources as well as high geometrical and radiometric qualities of their results. A method based on virtual 3D reconstruction of objects (scenarios) and the further 2.5 D maps generation by means of the Shape from Shading method for simulating the reflectance properties of surfaces within 2D images is being proposed. This alternative, seldom used when studying Urban-Architectural Heritage, is aimed at overcoming inadequacies when analyzing surfaces from the bi-dimentional view -or the three-dimensional one itself- over areas with little variations in elevation (relevant to urbanarchitectural context). The methodology is applied to VillagarcĒa de Campo Castle, Spain, stemming from the reconstruction of the property by the General Photogrammetry Method until achieving "Images by Reflectance Transformation", and ending by interpreting its topography for the inspection of un-documented historical traces.
[Work-related accidents on oil drilling platforms in the Campos Basin, Rio de Janeiro, Brazil].
Freitas, C M; Souza, C A; Machado, J M; Porto, M F
The offshore oil industry is characterized by complex systems in relation to technology and organization of work. Working conditions are hazardous, resulting in accidents and even occasional full-scale catastrophes. This article is the result of a study on work-related accidents in the offshore platforms in the Campos Basin, Rio de Janeiro State. The primary objective was to provide technical back-up for both workers' representative organizations and public authorities. As a methodology, we attempt to go beyond the immediate causes of accidents and emphasize underlying causes related to organizational and managerial aspects. The sources were used in such a way as to permit classification in relation to the type of incident, technological system, operation, and immediate and underlying causes. The results show the aggravation of safety conditions and the immediate need for public authorities and the offshore oil industry in Brazil to change the methods used to investigate accidents in order to identify the main causes in the organizational and managerial structure of companies.

Stochastic modelling of turbidite reservoirs constrained by seismic information (Campos basin, offshore Brazil)
Souza, J.; Olinto, G.; Eschard, R. [and others
A new methodology of reservoir probabilistic modelling was applied at an oil field scale in the brazilian continental margin. The Namorado field, located in the Campos basin in the passive margin of eastern Brazil, is a mature oil field with 60 wells and 1326 km of 3D seismic lines. The reservoir (Albian/Cenomanian), deposited in an overall-transgressive context, produces from turbidite sandstones and is composed by massive sandstones, classical Bouma turbidities, debris-flows, marls and shales. Three depositional sequences were correlated across the field, each of them corresponding to cycles of relative sea-level falls. The stochastic simulation of the spatial lithofacies distribution as a non stationary truncated gaussian function was carried out to generate realistic reservoir images. The important lateral variation in the facies and thickness of the sedimentary bodies is characteristic of non stationarity. In this case, the seismic data integration is crucial for a successful modelling of the phenomenon. A reservoir oriented processing of the seismic data was carried out, including a post-stack stratigraphic inversion. Seismic attributes on inversion results were calibrated at wells in terms of lithofacies. In the non stationary approach, the images of the reservoir lithofacies distribution are conditioned to wells and deduced from the Vertical Proportion Matrix, which represents the percentage of each lithofacies at a given spatial coordinate and in each depositional sequence. This matrix, defined over a regular grid, is computed from wells and seismic derived constraints. The incorporation of the seismic information in the non stationary gaussian function model has ensured a successful reproduction of the reservoir architecture.

Phylogenetic analysis of the microbial community in hypersaline petroleum produced water from the Campos Basin.
Piubeli, Francine; Grossman, Matthew J; Fantinatti-Garboggini, Fabiana; Durrant, Lucia R
In this work the archaea and eubacteria community of a hypersaline produced water from the Campos Basin that had been transported and discharged to an onshore storage facility was evaluated by 16S recombinant RNA (rRNA) gene sequence analysis. The produced water had a hypersaline salt content of 10 (w/v), had a carbon oxygen demand (COD) of 4,300 mg/l and contains phenol and other aromatic compounds. The high salt and COD content and the presence of toxic phenolic compounds present a problem for conventional discharge to open seawater. In previous studies, we demonstrated that the COD and phenolic content could be largely removed under aerobic conditions, without dilution, by either addition of phenol degrading Haloarchaea or the addition of nutrients alone. In this study our goal was to characterize the microbial community to gain further insight into the persistence of reservoir community members in the produced water and the potential for bioremediation of COD and toxic contaminants. Members of the archaea community were consistent with previously identified communities from mesothermic reservoirs. All identified archaea were located within the phylum Euryarchaeota, with 98 % being identified as methanogens while 2 % could not be affiliated with any known genus. Of the identified archaea, 37 % were identified as members of the strictly carbon-dioxide-reducing genus Methanoplanus and 59 % as members of the acetoclastic genus Methanosaeta. No Haloarchaea were detected, consistent with the need to add these organisms for COD and aromatic removal. Marinobacter and Halomonas dominated the eubacterial community. The presence of these genera is consistent with the ability to stimulate COD and aromatic removal with nutrient addition. In addition, anaerobic members of the phyla Thermotogae, Firmicutes, and unclassified eubacteria were identified and may represent reservoir organisms associated with the conversion hydrocarbons to methane.

Challenges towards the elimination of Human African Trypanosomiasis in the sleeping sickness focus of Campo in southern Cameroon.
Simo, Gustave; Mbida Mbida, Jean Arthur; Ebo'o Eyenga, Vincent; Asonganyi, Tazoacha; Njiokou, Flobert; Grķbaut, Pascal
The sleeping sickness focus of Campo lies along the Atlantic coast and extends along the Ntem River, which constitutes the Cameroonian and Equatorial Guinean border. It is a hypo-endemic focus with the disease prevalence varying from 0.3 to 0.86% during the last few decades. Investigations on animal reservoirs revealed a prevalence of Trypanosoma brucei gambiense of 0.6% in wild animals and 4.83% in domestic animals of this focus. From 2001 to 2012, about 19 931 tsetse were collected in this focus and five tsetse species including Glossina palpalis palpalis, G. pallicera, G. nigrofusca, G. tabaniformis and G. caliginea were identified. The analysis of blood meals of these flies showed that they feed on human, pig, goat, sheep, and wild animals such as antelope, duiker, wild pig, turtle and snake. The percentage of blood meals taken on these hosts varies according to sampling periods. For instance, 6.8% of blood meals from pig were reported in 2004 and 22% in 2008. This variation is subjected to considerable evolutions because the Campo HAT focus is submitted to socio-economic mutations including the reopening of a new wood company, the construction of autonomous port at "Kribi" as well as the dam at "Memve ele". These activities will bring more that 3000 inhabitants around Campo and induce the deforestation for the implementation of farmlands as well as breeding of domestic animals. Such mutations have impacts on the transmission and the epidemiology of sleeping sickness due to the modification of the fauna composition, the nutritional behavior of tsetse, the zoophilic/anthropophilic index. To achieve the elimination goal in the sleeping sickness focus of Campo, we report in this paper the current epidemiological situation of the disease, the research findings of the last decades notably on the population genetics of trypanosomes, the modifications of nutritional behavior of tsetse, the prevalence of T. b. gambiense in humans, domestic and wild animals. An overview on the types of mutations occurring in the region has been raised and a discussion on the strategies that can be implemented to achieve the elimination of the disease has been made.

Continuous Mantle Exhumation at the Outer Continental Margin of the Santos, Campos and EspĒrito Santo Basins, Brazil
NASA Astrophysics Data System (ADS)
Zalan, P. V.; Severino, M. G.; Rigoti, C. A.; Magnavita, L. P.; Oliveira, J. B.; Viana, A. R.
The interpretation of 12,000 km of very deep (PSTM to 16 sec., PSDM to 25 km) 2D seismic sections, coupled with gravimetric and magnetometric modeling line-by-line, and the integration of the results with the regional data bank of Petrobras, all together viewed in terms of the recent tectonic models developed for the rupturing and separation of mega-plates, led to a regional (500,000 km2), first-time ever, 3D-view of the deep structure underlying the prolific sedimentary basins of Santos, Campos and EspĒrito Santo in southeastern Brazil. The three basins are situated onto a continental margin that narrows gradually, from south to north, from a very wide (Santos), through an intermediate (Campos), and then to a narrow (EspĒrito Santo) passive margin. The seismic sections shows very well the dual rheological behavior of the continental crust, consisting of a deeper and plastic lower crust (with numerous short and strong reflections that display sub-horizontal ductile flow) and a shallower and brittle upper crust (represented by a mostly transparent and faulted seismic facies topped by the sedimentary sections of the rift and thermal subsidence phases). The crustal structure of the Santos Basin shows a zonation from west to east of alternating bands of NE-SW-trending thin (plastic basement terrains) and thick (resistant basement terrains) stretched continental crust. In vertical section this zonation is displayed as a series of necking zones, leading to a highly irregular, low to moderate crustal taper. Such zonation is less developed in the Campos Basin, where the crustal taper is moderate and regular, and practically non-existent in the EspĒrito Santo Basin, where the crustal taper is high. The most outstanding crustal feature shared in common by the three basins is the exhumation of mantle between the tip of the hyper-extended continental crust and the tabular-shaped oceanic crust. Although the crustal taper varies significantly from basin to basin their continental crust pinches out invariably on the flanks of exhumed mantle. This gives rise to a remarkable long (900 km along a N-S direction and 600 km in E-W direction), relatively narrow (15 to 70 km wide) and continuous belt of exhumed mantle that marks the passage from continental crust to oceanic crust in all three basins. The Santos, Campos and EspĒrito Santo Basins thus form a typical magma-poor passive margin. These are in sharp contrast with the adjacent basin to the south, the Pelotas Basin, that in turn is a typical volcanic passive margin displaying a long (1000 km in a N-S direction) and wide (100 to 220 km) belt of seaward-dipping reflectors at its outer margin and no exhumation of the mantle at the continent-ocean boundary.
Productive reorganization, outsourcing, and work relations in the offshore oil industry in the Campos Basin, Rio de Janeiro.
Figueiredo, Marcelo; Alvarez, Denise; Athayde, Milton; Suarez, Josķ Diego; Pereira, Renata; Soares, Leonardo
This article analyzes the relationship between the intensive use of outsourcing and labor organizations on offshore oil platforms in the Campos Basin, Rio de Janeiro, Brazil. The theoretical and methodological framework applied in our research is based on Ergonomics of Activity and the Psychodynamics of Work, from an ergological perspective. In addition to the more general trend of increasing precariousness, we highlight the potential loss of formal and informal knowledge resulting from the fragmentation of work collectives, as we consider the cohesion of these collectives to be a crucial element contributing to reliability in process operations. Increasing precariousness of work contributes to this fragmentation and one of its main causes is the uncontrolled increase in outsourcing of work. This situation has had nefarious consequences for workers' health and safety, suggesting that those who have adopted outsourcing as a labor management tool have failed to consider these harmful consequences as rigorously as necessary.

Strains of the East Asian (W/Beijing) Lineage of Mycobacterium tuberculosis Are DosS/DosT-DosR Two-Component Regulatory System Natural Mutants? å
Fallow, Ashley; Domenech, Pilar; Reed, Michael B.
As part of our ongoing efforts to uncover the phenotypic consequences of genetic variability among clinical Mycobacterium tuberculosis isolates, we previously reported that isolates of the ōEast Asianö or ōW/Beijingö lineage constitutively overexpress the coordinately regulated transcriptional program known as the DosR regulon under standard in vitro conditions. This phenotype distinguishes the W/Beijing lineage from all other M. tuberculosis lineages, which normally induce expression of this regulon only once exposed to low oxygen or nitric oxide, both of which result in inhibition of bacterial respiration and replication. Transcription of the DosR regulon is controlled through a two-component regulatory system comprising the transcription factor DosR and two possible cognate histidine sensor kinases, DosS and DosT. Through sequence analysis of a carefully selected set of isolates representing each of the major M. tuberculosis lineages, we describe herein a naturally occurring frameshift mutation in the gene encoding the DosT sensor kinase for isolates of the most recently evolved W/Beijing sublineages. Intriguingly, the occurrence of the frameshift mutation correlates precisely with the appearance of the constitutive DosR regulon phenotype displayed by the same ōmodernö W/Beijing strains. However, complementation studies have revealed that the mutation in dosT alone is not directly responsible for the constitutive DosR regulon phenotype. Our data serve to highlight the evolutionary pressure that exists among distinct M. tuberculosis lineages to maintain tight control over DosR regulon expression. PMID:20154135
Use and valuation of native and introduced medicinal plant species in Campo Hermoso and Zetaquira, Boyacß, Colombia
Background Medicinal plant species contribute significantly to folk medicine in Colombia. However, few local studies have investigated whether species used are introduced or native and whether there is a difference in importance of native and introduced medicinal plant species. The aim of the present study was to describe the use of medicinal plants within two municipalities, Campo Hermoso and Zetaquira, both in the department of Boyacß, Colombia and to assess the importance of native and introduced plants to healers, amateur healers and local people. As local healers including amateur healers have no history of introduced species our working hypotheses (H1-2) were that H1: native and introduced medicinal plant species are of equal importance and H2: healers and amateur healers do not differentiate in their preferences between native and introduced medicinal plant species. Methods Ten villages were included in the study. A combination of quantitative and qualitative methods was used including questionnaires, semi-structured interviews, in- depth interviews, and open talks. Voucher specimens were collected in home gardens and during field walks. For data analysis, we calculated use value indices and Jaccard index and tested for the above hypothesis using Spearman rank-correlation coefficients and Wilcoxon-Mann¢Whitney tests. Results Eighty medicinal plant species were described by locals as the most frequently used. Of these, 78 species were taxonomically identified, distributed within 41 families and 74 genera, which included 35 native species and 43 introduced. The highest valued families were: Asteraceae, Lamiaceae, Apiaceae, Rutaceae and Verbenaceae. The species ranked highest according to their Use Values, in both municipalities, were Mentha suaveolens Ehrh., Ambrosia cumanensis Kunth, and Verbena littoralis Kunth. Introduced species were more important than native ones in Zetaquira, while there was no difference in importance in Campo Hermoso. While healers relied most on the uses of native species, amateur healers were inclined to rely on introduced species. Medicinal plant administration in both municipalities follow the usual pattern: Leaves are used most commonly prepared by decoction or infusion and administrated orally. Conclusions The high proportion of introduced plant species used in the local traditional medicines is similar to the results of a number of other ethnobotanical studies and emphasise the need for efforts to record and maintain traditional knowledge on native species.

Fast interrupt platform for extended DOS
NASA Technical Reports Server (NTRS)
Duryea, T. W.
Extended DOS offers the unique combination of a simple operating system which allows direct access to the interrupt tables, 32 bit protected mode access to 4096 MByte address space, and the use of industry standard C compilers. The drawback is that fast interrupt handling requires both 32 bit and 16 bit versions of each real-time process interrupt handler to avoid mode switches on the interrupts. A set of tools has been developed which automates the process of transforming the output of a standard 32 bit C compiler to 16 bit interrupt code which directly handles the real mode interrupts. The entire process compiles one set of source code via a make file, which boosts productivity by making the management of the compile-link cycle very simple. The software components are in the form of classes written mostly in C. A foreground process written as a conventional application which can use the standard C libraries can communicate with the background real-time classes via a message passing mechanism. The platform thus enables the integration of high performance real-time processing into a conventional application framework.
Transformation of the Extended Gamma Function Gamma>^2,0_0,2 [(b,x)] with Applications to Astrophysical Thermonuclear Functions DOS Campos, Brazil, 10-14 November 1997.
NASA Astrophysics Data System (ADS)
Aslam Chaudhry, M.
Two representations of the extended gamma functions Gamma^2,0_0,2 [(b,x)] are proved. These representations are exploited to find a transformation relation between two Fox's H-functions. These results are used to solve Fox's H-function in terms of Meijer's G-function for certain values of the parameters. A closed form representation of the kernel of the Bessel type integral transform is also proved.
Upper Cretaceous bioturbated fine-to-medium sands: A problem for deep-water exploration in Campos Basin, Offshore Brazil
Carminatti, M.; Zimmermann, L.; Jahnert, R.; Pontes, C.
The presence of bioturbation in oil-prone turbidite deposits has detained a better exploration of upper Cretaceous siliciclastic reservoirs in Campos Basin. Bioturbated sandstones have degraded their permo-porosity with impact in oil production. They occur associated to unbioturbated sandstones with similar seismic amplitude, becoming difficult to separate them in seismic mapping. A comprehensive study in order to reduce the exploratory risk must consider firstly the recognition of genetic facies association through cores, and secondly the calibration of sonic well-logs and seismic velocity sections with rock data. This study deals with sedimentary facies association. The range of main facies in such reservoirs includes: (1) medium-to-coarse siliciclastic sandstone with cross stratification; (2) fine-to-medium massive sandstone with thin traction carpets, bioturbated by opportunistic ichnofabrics and, (3) bioturbated, muddy, fine-to-medium, quartz-feldspatic and glauconitic sandstone over 60 in thick. The genetic facies associations suggest that the sandwich reservoirs were formed by high density turbidite currents deposited en masse or by thin traction carpets. The bioturbated sandstone was originated by reworking of bottom currents rich in nutrients and oxygen. Detritic and biogenic glauconite covered and/or filled bioturbations indicate a basinward movement of the bottom currents. The successive alternation of high-energy with low-energy ichnofabrics reflects cyclic variations in current velocities.

Godwin Ansa; Haitham Criuckshank; Zhili Sun; Mohammad Al-Siyabi
Packet injection by an attacker can trigger flooding- based DOS attacks. This paper seeks to provide a simple and robust approach to protect the access control, data integrity and sender authentication security services in resource-constrained delay tolerant networks. The aim is to make security protocols providing these mandatory security services resilient to resource exhaustion DOS attacks. To achieve this we
Directional Resonance and Wavefield Polarization in the Damage Zone of the Campo Imperatore Fault Zone (central Italy).
NASA Astrophysics Data System (ADS)
Pischiutta, M.; Fondriest, M.; Demurtas, M.; Di Toro, G.; Rovelli, A.
To infer the occurrence of directional amplification effects, we performed ambient noise measurements along a 200m transect crossing the Campo Imperatore fault zone (Central Italy), an exhumed analogue of the faults responsible of the L'Aquila 2009 earthquake sequence, We have recently found in several fault zones that ambient noise is not randomly polarized, but it is amplified on the horizontal plane along a specific site-dependent direction. The analysis repeated using earthquake signals revealed that S-coda waves and surface waves show the same polarization direction, independently of the earthquake backazimuth and focal mechanism. We have explained the observed directional amplifications in terms of fractured rocks in the fault damage zone, polarization being oriented orthogonally to fractures produced by the kinematic stress component. Therefore ground motion directional amplification could be related to the higher compliance of fractured rocks. In the other studies the fracture pattern was derived from numerical-analytical modeling based on the fault geometry and kinematics, or compared with the fast direction of shear wave obtained by seismic anisotropy analysis. The aim of this study is to compare observations with fracture measurements (strike, dip, dip-azimuth, spacing, later continuity, etc.) performed in the selected fault zone. We thus acquired ambient noise using 25 stations installed along a transect where detailed structural geological measurements were carried out. Ambient noise was recorded for around 1 hour, and was processed to compute the horizontal-to-vertical noise spectral ratio as a function of frequency and direction of motion. Wavefield polarization was investigated in the time-frequency domain as well. We found that, in spite of the complexity of the seismic data, the observed polarization pattern is generally oriented orthogonal to the measured dominant fracture system, confirming the existence of a high angle relation between ground motion polarization and fracture systems.
Volcanism-sedimentation interaction in the Campo de Calatrava Volcanic Field (Spain): a magnetostratigraphic and geochronological study
NASA Astrophysics Data System (ADS)
Herrero-Hernßndez, Antonio; L¾pez-Moro, Francisco Javier; Gallardo-Millßn, Josķ Luis; MartĒn-Serrano, ┴ngel; G¾mez-Fernßndez, Fernando
This work focuses on the influence of Cenozoic volcanism of the Campo de Calatrava volcanic field on the sedimentation of two small continental basins in Spain (Argamasilla and Calzada-Moral basins). The volcanism in this area was mainly monogenetic, according to the small-volume volcanic edifices of scoria cones that were generated and the occurrence of tuff rings and maars. A sedimentological analysis of the volcaniclastic deposits led to the identification of facies close to the vents, low-density (dilute) pyroclastic surges, secondary volcanic deposits and typical maar deposits. Whole-rock K/Ar dating, together with palaeomagnetic constraints, yielded an age of 3.11-3.22 Ma for the onset of maar formation, the deposition finished in the Late Gauss-Early Matuyana. Using both techniques and previous paleontological data allowed it to be inferred that the maar formation and the re-sedimentation stage that occurred in Argamasilla and Calzada-Moral basins were roughly coeval. The occurrence of syn-eruption volcaniclastic deposits with small thicknesses that were separated by longer inter-eruption periods, where fluvial and lacustrine sedimentation was prevalent, together with the presence of small-volume volcanic edifices indicated that there were short periods of volcanic activity in this area. The volcanic activity was strongly controlled by previous basement faults that favoured magma feeding, and the faults also controlled the location of volcanoes themselves. The occurrence of the volcanoes in the continental basins led to the creation of shallow lakes that were related to the maar formation and the modification of sedimentological intra-basinal features, specifically, valley slope and sediment load.
Natural incidence of egg parasitoids of Edessa meditabunda (F.) (Hemiptera: Pentatomidae) on Crotalaria spectabilis in Campo Novo do Parecis, MT, Brazil.

The Heme-Based Oxygen-Sensor Phosphodiesterase Ec DOS (DosP): Structure-Function Relationships
Shimizu, Toru
Escherichia coli Direct Oxygen Sensor (Ec DOS, also known as Ec DosP) is a heme-based O2-sensing phosphodiesterase from Escherichia coli that catalyzes the conversion of cyclic-di-GMP to linear di-GMP. Cyclic-di-GMP is an important second messenger in bacteria, highlighting the importance of understanding structure-function relationships of Ec DOS. Ec DOS is composed of an N-terminal heme-bound O2-sensing PAS domain and a C-terminal phosphodiesterase catalytic domain. Notably, its activity is markedly enhanced by O2 binding to the heme Fe(II) complex in the PAS sensor domain. X-ray crystal structures and spectroscopic and catalytic characterization of the wild-type and mutant proteins have provided important structural and functional clues to understanding the molecular mechanism of intramolecular catalytic regulation by O2 binding. This review summarizes the intriguing findings that have obtained for Ec DOS. PMID:25586128
Resist DoS attacks in UMTS-WLAN
NASA Astrophysics Data System (ADS)
Qu, Huyu; Cheng, Qiang
Wireless network is more vulnerable to denial of service (DoS) attacks than wired one. In this paper we propose two methods to resist DoS attacks in UMTS-WLAN network, one is active and the other is passive. These two are complementary to each other. In active DoS defense method, a mobile terminal generates an authorized anonymous ID (AAI) using its true ID such as IP address, MAC address, PIN code, or asymmetric key, and substitutes its true ID with the authorized anonymous ID. The mobile terminal may be authenticated by the UMTS-WLAN, however its true ID is anonymous to intending attackers. This method can be used to isolate de-authenticating/disassociating DoS attackers, spoofing power-save DoS attacker, etc. In passive DoS defense method, we propose a trace back scheme. We use covert channels in the header of mobile IP packets to trace back the malicious nodes by embedding some address information of intermediate nodes, and recovering the embedded information by the victim. After the victim successfully traces the attacking paths from malicious nodes, it can segregate the malicious nodes and protect itself. This method can be used to resist DoS attacks of mass-produced junk message congestions.
Slope sedimentary facies associated with Pleistocene and Holocene sea-level changes, Campos Basin, southeast Brazilian Margin
NASA Astrophysics Data System (ADS)
Caddah, Luiz Fernando G.; Kowsmann, Renato O.; Viana, Adriano R.
The upper Quaternary section of Campos Basin continental slope was sampled by 56 piston cores and 5 HPC boreholes totalling 750 m of core. Muds comprise 77% of the cored section and were classified according to colour, which results mostly -from their carbonate and sulphide contents. In the uppermost part of the section (0.5-15 m), where less reducing conditions prevail, slope muds are brown and olive in colour and, respectively, pelagic and hemipelagic in origin. This packet shows a coarsening-upward pattern in the upper slope with Upper Pleistocene olive grey mud at the base, olive grey mud/silty-sand intercalations in the middle and Holocene muddy-sand at the top. As this packet thins considerably downslope, average sedimentation rates range from 26 to 2.0 cm/ka. The contact between olive and the underlying greenish muds is diachronous, occurring at 26 ka in the lower slope and 40 ka in the upper slope. The greenish muds are characterized by a wider range of carbonate content (3-50%) and disseminated sulphide content, including siliciclastic muds of greenish-black and dark greenish-grey colour, hemipelagic greenish-grey muds and pelagic light greenish-grey marls. Intercalated with the siliciclastic muds, shelf-spillover sands (bioturbated muddy sands and thin-bedded turbidites) occur in the upper slope and hemipelagic/pelagic muds in the lower slope. Upper-slope gullies and channels are locally filled with medium- to thick-bedded turbidite sands. Based on current measurements, and on the distribution and sedimentary structures in the bioturbated muddy sands, a reworking or sweeping action by bottom currents is inferred. During Pleistocene lowstands, darker siliciclastic muds, richer in sulphide, are more common denoting a higher terrestrial influence. Mass movement deposits, identified in the southern part of the study area, were also associated with eustatic lowstands. Four discrete slump units, with an average thickness of 50 m, cover an area of 1600 km'. Between these slump deposits, seismically well-layered units are formed by an alternation of dark greenish-grey and greenish-black muds. Palaeontological data and numerical modelling of excess pore pressures generated from water and sediment loading suggest that the emplacement of the youngest slump unit occurred over a 15-ka period from 68 ka to 53 ka. This deformation is inferred to result from accelerated creep triggered by the decrease in hydrostatic pressure during sea-level fall. During the last Pleistocene highstand, upper/middle slope sedimentation was depleted in plant debris denoting a weaker terrestrial influence and, on the lower slope, hemipelagic/pelagic sedimentation was more common.
Genesis of the Angra dos Reis and other achondritic meteorites
NASA Technical Reports Server (NTRS)
Ma, M.-S.; Murali, A. V.; Schmitt, R. A.
Major, minor, and trace element abundances were determined in seven Angra dos Reis samples, which included whole rocks, fassaite (clinopyroxene), olivine, and whitlockite separates, via sequential instrumental neutron activation analysis. The rare earth element abundance patterns and the trace element abundance patterns of this achondritic meteorite are discussed. A two-stage crystal-liquid fractionation model with source material containing olivine, orthopyroxene, and clinopyroxine is presented for the genesis of Angra dos Reis. Multilinear regression analysis was used to estimate possible composition and properties of the parent magmas. Angra dos Reis was compared with other achondrites, cumulate eucrites and nakhlites in particular. It is thought that the unique Angra dos Reis could not be related to those achondrites by crystal-liquid fractionation of the same parent body.

Environmental impact studies of barium and radium discharges by produced waters from the ōBacia de Camposö oil-field offshore platforms, Brazil
S. F Jerez Vegueria; J. M Godoy; N Miekeley
Produced water samples from different E&P offshore petroleum platforms, belonging to the Bacia de Campos oil field, Brazil, were analyzed for barium, 226Ra and 1Ra. The concentrations measured are in the range of 0.36¢25.7mgl?1 for barium, 0.012¢6.0Bql?1 for 226Ra and <0.05¢12.0Bql?1 for 1Ra. A strong correlation between the concentration of barium and radium isotopes was observed (226Ra: r2=0.926; 228Ra: r2=0.785).
Genetic gains in the UENF-14 popcorn population with recurrent selection.
Freitas, I L J; do Amaral J·nior, A T; Freitas, S P; Cabral, P D S; Ribeiro, R M; Gonńalves, L S A
The popcorn breeding program of Universidade Estadual do Norte Fluminense Darcy Ribeiro aims to provide farmers a cultivar with desirable agronomic traits, particularly with respect to grain yield (GY) and popping expansion (PE). We evaluated full-sib families from the seventh cycle of recurrent selection and estimated the genetic progress with respect to GY and PE. Eight traits were evaluated in 200 full-sib families that were randomized into blocks with two replicates per set in two contrasting environments, Campos dos Goytacazes and Itaocara, located in north and northwest Rio de Janeiro State, respectively. There were significant differences between sets in families with respect to all traits evaluated, which indicates genetic variability that may be explored in future cycles. Using random economic weights in the selection of superior progenies, the Mulamba and Mock index showed gains for PE and GY of 5.11 and 7.78%, respectively. Significant PE and GY increases were found when comparing the evolution of mean values of these two parameters that were assessed at cycles C?-C? and predicted for C?. Thus, an advanced-cycle popcorn cultivar with genotypic superiority for the main traits of economic interest can be made available to farmers in Rio de Janeiro State. PMID:24535880
Genetic progress in the UNB-2U population of popcorn under recurrent selection in Rio de Janeiro, Brazil.
Ribeiro, R M; do Amaral J·nior, A T; Gonńalves, L S A; Candido, L S; Silva, T R C; Pena, G F
As part of the Universidade Estadual do Norte Fluminense recurrent selection program of popcorn, we evaluated full-sib families of the sixth cycle of recurrent selection and estimated genetic progress for grain yield and expansion capacity. We assessed 200 full-sib families for 10 agronomic traits, in a randomized block design, with two replications within sets in two environments: Campos dos Goytacazes and Itaocara, in the State of Rio de Janeiro, Brazil. There were significant differences for families/"sets" for all traits, indicating genetic variability that could be exploited in future cycles. In the selection of superior progenies, the Mulamba and Mock index gave the best gains for popping expansion (PE) and grain yield (GY), with values of 10.97 and 15.30%, respectively, using random economic weights. By comparing the evolution of the means obtained for PE and GY in the cycles C(0), C(1), C(2), C(3), C(4), C(5), and predicted for C(6), a steady increase was observed for both PE and GY, with the addition of 1.71 mL/g (R(2) = 0.93) and 192.87 kg/ha (R(2) = 0.88), respectively, in each cycle. Given the good performance of this popcorn population in successive cycles of intrapopulation recurrent selection, we expect that a productive variety with high expansion capacity will soon be available for producers in the north and northwest regions of Rio de Janeiro State, Brazil.

Isotopic and chemical investigations on Angra dos Reis
NASA Technical Reports Server (NTRS)
Wasserburg, G. J.; Tera, F.; Papanastassiou, D. A.; Huneke, J. C.
Isotope ratios and chemical abundance measurements for a variety of elements are reported for total meteorite and mineral separates of the Angra dos Reis achondrite. U-Pb, Th-Pb, and Pb-Pb ages are concordant at 4.54 eons for the total meteorite and for high-purity whitlockite, which indicates that Angra dos Reis is an early planetary differentiate that has not been disturbed for these systems since 4.54 eons ago. The implications of different ratios of Sr-87 and Sr-86 found in different components are discussed. Xe isotopic measurements show that Pu-244 was enriched in the whitlockite relative to the pyroxene by a factor of about 18. Chemical enrichment factors between the whitlockite and the fassaitic pyroxene in Angra dos Reis are presented

Stealth-MITM DoS Attacks on Secure Channels
Herzberg, Amir
We define stealth Man-in-the-Middle adversaries, and analyse their ability to launch denial and degradation of service (DoS) attacks on secure channels. We show realistic attacks, disrupting TCP communication over secure VPNs using IPsec. We present: First amplifying DoS attack on IPsec, when deployed without anti-replay window. First amplifying attack on IPsec, when deployed with a `small' anti-replay window, and analysis of `sufficient' window size. First amplifying attack on IPsec, when deployed with `sufficient' window size. This attack (as the previous) is realistic: attacker needs only to duplicate and speed-up few packets. We also suggest a solution designed to prevent the presented attacks, and to provide secure channel immune to degradation and other DoS attacks. Our solution involves changes (only) to the two gateway machines running IPsec. In addition to their practical importance, our results also raise the challenge of formally defining secure channels immune to DoS and degradation attacks, and p...

The Campo de Dalias is an area with relevant seismicity associated to the active tectonic deformations of the southern boundary of the Betic Cordillera. A non-permanent GPS network was installed to monitor, for the first time, the fault- and fold-related activity. In addition, two high precision levelling profiles were measured twice over a one-year period across the Balanegra Fault, one of the most active faults recognized in the area. The absence of significant movement of the main fault surface suggests seismogenic behaviour. The possible recurrence interval may be between 100 and 300 y. The repetitive GPS and high precision levelling monitoring of the fault surface during a long time period may help us to determine future fault behaviour with regard to the existence (or not) of a creep component, the accumulation of elastic deformation before faulting, and implications of the fold-fault relationship.

New client puzzle outsourcing techniques for DoS resistance
Brent Waters; Ari Juels; J. Alex Halderman; Edward W. Felten
We explore new techniques for the use of cryptographic puzzles as a countermeasure to Denial-of-Service (DoS) attacks. We propose simple new techniques that permit the out-sourcing of puzzles; their distribution via a robust external service that we call a bastion. Many servers can rely on puzzles distributed by a single bastion. We show how a bastion, somewhat surprisingly, need not

Ultrafast ligand dynamics in the heme-based GAF sensor domains of the histidine kinases DosS and DosT from Mycobacterium tuberculosiså
Vos, Marten H.; Bouzhir-Sima, Latifa; Lambry, Jean-Christophe; Luo, Hao; Eaton-Rye, Julian J.; Ioanoviciu, Alexandra; Ortiz de Montellano, Paul R.; Liebl, Ursula
The transcriptional regulator DosR from M. tuberculosis plays a crucial role in the virulence to dormancy transition of the pathogen. DosR can be activated by DosT and DosS, two histidine kinases with heme-containing sensor GAF domains, capable of diatomic ligand binding, To investigate the initial processes occurring upon ligand dissociation, we performed ultrafast time-resolved absorption spectroscopy of the isolated sensor domains ligated with O2, NO and CO. The results reveal a relatively closed heme pocket for both proteins. For DosT the yield of O2 escape from the heme pocket on the picoseconds timescale upon photodissociation was found to be very low (1.5%), similar to other heme-based oxygen sensor proteins, implying that this sensor acts as an effective O2 trap. Remarkably, this yield is an order of magnitude higher in DosS (18%). For CO, by contrast, the fraction of CO rebinding within the heme pocket is higher in DosS. Experiments with mutant DosT sensor domains and molecular dynamics simulations indicate an important role in ligand discrimination of the distal tyrosine, present in both proteins, which forms a hydrogen bond with heme-bound O2. We conclude that despite their similarity, DosT and DosS display ligand-specific different primary dynamics during the initial phases of intra-protein signaling. The distal tyrosine, present in both proteins, plays an important role in these processes. PMID:22142262

The Permian post-orogenic collapse in the Alps: insights from the Campo unit (Austroalpine nappes, N-Italy, SE-Switzerland)
NASA Astrophysics Data System (ADS)
Petri, BenoŅt; Mohn, Geoffroy; ŖtĒpskß, Pavla; Manatschal, Gianreto; Schulmann, Karel
The final stage of the Variscan orogeny (310-270 Ma) is characterized by an intense tectonic, magmatic and metamorphic event. During the Permian, acid and mafic intrusions were emplaced at all crustal levels and are associated to high-temperature contact metamorphism. While most of the studies focus either on the formation of Permian basins or on the lower crustal magmatic and metamorphic evolution, the characterization of the middle crust is lacking. Therefore, this study aims to unravel the processes active at mid-crustal levels during the Permian. We investigate the contact aureole of the Sondalo gabbro emplaced in a mid-crustal position during the Permian, exposed in the Austroalpine Campo unit (N-Italy). This work is based on a multidisciplinary approach linking structural geology, metamorphic petrology and geochronology. The country rock of the gabbroic intrusion is composed of Grt-St micaschists and paragneisses indicating a prograde path in the amphibolite facies associated with the formation of a N-W steeply dipping S2 foliation. This foliation is pervasively reworked by a N-E trending sub-vertical S3 fabric made of Ms-Bt metasediments. This S3 fabric is also found in metapelitic septa in the core of the mafic intrusion, whereas in the narrow contact aureole a moderately dipping S4 fabric roughly parallel to the margins of the pluton is developed. From host-rock to the center of the intrusion, the metapelites show destabilization of muscovite, appearance of sillimanite, spinel, cordierite, crystallization of a large amount of garnet and finally disappearance of biotite and potassic feldspar. As a consequence, the kinzigitic restites of the contact aureole are replaced by Grt-Sil-Crd-Spl granulites in an intra-plutonic position. Qualitative P-T estimates indicate a barrovian prograde path during D2, similar to P-T evolutions found in other Austroalpine units (e.g. Ulten zone). Thermodynamic modelling of the high-grade granulites due to the thermal effect of the ~290 Ma (U-Pb on zircon) mafic intrusion give conditions of ~6 kbar and > 900░C. Our results bring constrains on the thermal and mechanical relation between the pluton and the host rock in the middle crust and confirm the mid-crustal position of the Campo unit during the Permian. Furthermore, this study highlights the contrasted evolution of mid-crustal levels compared to lower-crustal systems such as the Ivrea zone. Eventually at a larger scale, these results provide insights on the tectonic and magmatic processes and thermal conditions of the continental crust during Variscan post-orogenic evolution.

Hamacantha (Hamacantha) boomerang sp. nov. from deep-sea coral mounds at Campos Basin, SW Atlantic, and redescription of H. (H.) schmidtii (Carter, 1882) (Hamacanthidae, Poecilosclerida, Demospongiae).
Hajdu, Eduardo; Castello-Branco, Cristiana
There are 22 species of Hamacantha registered from all over the world, and frequently from deep-waters, only two of which had previously been reported from the SW Atlantic. Here we describe a third species for this area, Hamacantha (H.) boomerang sp. nov., collected from deep-sea coral mounds at Campos Basin (off Rio de Janeiro state). We found oxeas 271-630 Ąm long, diancistras in three size classes, 125-155, 45-69 and 20-29 Ąm, and toxas, 58-82 Ąm. This is the only Hamacantha combining oxeas and toxas, but the latter are very rare. The species approaches the Caribbean H. (H.) schmidtii (Carter, 1882), where we observed oxeas 390-495 Ąm long, and diancistras in three size classes, 109-124,Ā 44-54 and 26-41 ?m, however toxas appear to be absent. Both species are clearly distinct by micrometric values, as well as the overall morphology of the smaller diancistras, distinct from the intermediate category in the new species, but quite similar in H. (H.) schmidtii. Hamacantha (Vomerula) falcula approaches the new species very closely in microsclere dimensions and morphology, but is set apart by its styloid and smaller megascleres. PMID:24872308
Environmental impact studies of barium and radium discharges by produced waters from the "Bacia de Campos" oil-field offshore platforms, Brazil.
Jerez Vegueria, S F; Godoy, J M; Miekeley, N
Produced water samples from different E&P offshore petroleum platforms, belonging to the Bacia de Campos oil field, Brazil, were analyzed for barium, 226Ra and 'Ra. The concentrations measured are in the range of 0.36-25.7 mg l(-1) for barium, 0.012-6.0 Bq l(-1) for 226Ra and <0.05-12.0 Bq l(-1) for 1Ra. A strong correlation between the concentration of barium and radium isotopes was observed (226Ra: r2=0.926: 228Ra: r2=0.785). Additionally, seawater and sediment samples were taken at different distances (from 250 to 1,000 m) from the two selected platforms. Water samples were analyzed for dissolved and particulate barium, 226Ra and 225Ra and the sediment samples for total and leachable barium, 226Ra and 228Ra. The results showed that even for the shortest sampling distance (250 m) from the discharge point, barium, 226Ra and 228Ra concentrations are similar to the local background, indicating that dispersion by local currents is enough to minimize environmental impacts.

Document image archive transfer from DOS to UNIX
NASA Technical Reports Server (NTRS)
Hauser, Susan E.; Gill, Michael J.; Thoma, George R.
An R&D division of the National Library of Medicine has developed a prototype system for automated document image delivery as an adjunct to the labor-intensive manual interlibrary loan service of the library. The document image archive is implemented by a PC controlled bank of optical disk drives which use 12 inch WORM platters containing bitmapped images of over 200,000 pages of medical journals. Following three years of routine operation which resulted in serving patrons with articles both by mail and fax, an effort is underway to relocate the storage environment from the DOS-based system to a UNIX-based jukebox whose magneto-optical erasable 5 1/4 inch platters hold the images. This paper describes the deficiencies of the current storage system, the design issues of modifying several modules in the system, the alternatives proposed and the tradeoffs involved.
Sedimentation survey of Lago Dos Bocas, Puerto Rico, June 1985
Quinones, Ferdinand; Melendez, Frank; Bonnet, Carlos
A survey of the sedimentation of Dos Bocas reservoir, in central Puerto Rico, was conducted during July 1985. The survey showed that the capacity of the reservoir has declined from 30,420 acre-ft in 1942 to about 19,620 acre-ft. Sediment is accumulating in the reservoir at an average rate of about 251 acre-ft/yr, or about 0.83%/yr of the original capacity. The expected usable life of the reservoir on the basis of the long-term sedimentation rate is about 78 years. However, the sedimentation rate appears to have increased significantly since 1979. During the last six years, the average sedimentation rate has exceeded 600 acre-ft/yr. If this rate is maintained, the expected usable life of the reservoir would be about 32 years.

Urano y sus dos satķlites irregulares recientemente descubiertos
NASA Astrophysics Data System (ADS)
Parisi, M. G.; Brunini, A.
Hasta hace poco tiempo, Urano era el ·nico de los Planetas Gigantes que no poseĒa satķlites irregulares. Esto lo diferenciaba del resto de los planetas Gigantes, al igual que la peculiar oblicuidad de su eje de spin. La gran inclinaci¾n de su eje de rotaci¾n se debe probablemente a una colisi¾n que sufri¾ el planeta con otro embri¾n planetario al final del proceso de formaci¾n. Esta colisi¾n habrĒa desligado satķlites exteriores preexistentes del planeta. Recientemente se han descubierto dos satķlites irregulares de Urano, lo que introduce algunas nuevas cotas y condiciones en el escenario de la "Hip¾tesis de la Gran Colisi¾n" . Los satķlites irregulares de Urano tuvieron que ser capturados en una etapa posterior a la del escenario de la Gran Colisi¾n, de no ser asĒ, hubieran sido eyectados del sistema por el impulso impartido con ese gran impacto. En este trabajo, se discuten los posibles mecanismos de captura de los satķlites irregulares y se presenta un nuevo posible mecanismo para dicha captura.
Effects of non-aqueous fluids-associated drill cuttings discharge on shelf break macrobenthic communities in the Campos Basin, Brazil.
Santos, Maria Fernanda L; Silva, Janete; Fachel, Jandyra M G; Pulgati, Fernando H
This paper assesses the effects of non-aqueous fluids (NAF)-associated drill cuttings discharge on shelf break macrobenthic communities in the Campos Basin, off the southeast Brazilian coast, Rio de Janeiro State. Samples were taken with a 0.25-m2 box corer from surrounding two oil and gas wells on three monitoring cruises: before drilling, three months after drilling, and 22 months after drilling. Statistical methodologies used Bayesian geostatistical and analysis of variance models to evaluate the effects of the NAF-associated drill cuttings discharge and to define the impact area. The results indicated that marked variations were not observed in the number of families between cruises, though there were changes in the fauna composition. The changes seen in biological descriptors in both control and background situation areas were not considered significant, showing a temporal homogeneity in means. The impact area presented changes in biological descriptors of communities and trophic structure during the three cruises and such changes were correlated to chemical and physical variables related to the drilling activities, as a result of the mix of drill cuttings and sediment and the anoxic conditions established in the substrate. In that area, three months after drilling, a decrease in diversity and an increase in density, motile deposit-feeders and Pol/Crp ratio, and dominance of opportunistic organisms, such as the capitellid Capitella sp., were observed and, 22 months after drilling, an increase of diversity, reduction of dominance of capitellid polychaete, changes in the fauna composition, and a dominance of opportunistic burrowing and tube-building organisms were observed, indicating an ecological succession process.

Mycobacterium tuberculosis (Mtb) must counter hypoxia within granulomas to persist. DosR, in concert with sensor kinases DosS and DosT, regulates the response to hypoxia. Yet Mtb lacking functional DosR colonize the lungs of C57Bl/6 mice, presumably owing to the lack of organized lesions with sufficient hypoxia in that model. We compared the phenotype of the ?-dosR, ?-dosS, and ?-dosT mutants to Mtb using C3HeB/FeJ mice, an alternate mouse model where lesions develop hypoxia. C3HeB/FeJ mice were infected via aerosol. The progression of infection was analyzed by tissue bacterial burden and histopathology. A measure of the comparative global immune responses was also analyzed. Although ?-dosR and ?-dosT grew comparably to wild-type Mtb, ?-dosS exhibited a significant defect in bacterial burden and pathology in vivo, accompanied by ablated proinflammatory response. ?-dosS retained the ability to induce DosR. The ?-dosS mutant was also attenuated in murine macrophages ex vivo, with evidence of reduced expression of the proinflammatory signature. Our results show that DosS, but not DosR and DosT, is required by Mtb to survive in C3HeB/FeJ mice. The attenuation of ?-dosS is not due to its inability to induce the DosR regulon, nor is it a result of the accumulation of hypoxia. That the in vivo growth restriction of ?-dosS could be mimicked ex vivo suggested sensitivity to macrophage oxidative burst. Anoxic caseous centers within tuberculosis lesions eventually progress to cavities. Our results provide greater insight into the molecular mechanisms of Mtb persistence within host lungs.

K?Ar and 40Ar/ 39Ar evidence for a Transamazonian age (2030-1970 Ma) for the granites and emerald-bearing K-metasomatites from Campo Formoso and CarnaĒba (Bahia, Brazil)
NASA Astrophysics Data System (ADS)
Giuliani, G.; Zimmermann, J.-L.; Montigny, R.
The Campo Formoso and CarnaĒba granites belong to a suite of middle Proterozoic magmatic rocks located in the northern part of the SŃo Francisco craton. They intrude the Archaen basement and Lower Proterozoic Jacobina volcanosedimentary series. Emerald-bearing K-metasomatites in the mining districts of Campo Formoso and CarnaĒba are developed within serpentinites at the contact with granite-related pegmatitic veins. K?Ar and 40Ar/ 39Ar measurements were performed on biotites and deuteric muscovites from these two granites, and phlogopites from the K-metasomatites. For the Campo Formoso granite, the biotites yield ages between 1875 ▒ 45 Ma and 1908 ▒ 47 Ma (2 ?) and the muscovites yield ages of 1897 ▒ 34 Ma and 2040 ▒ 24 Ma (2 ?). For the CarnaĒba granite, the biotites and muscovites fit isochrons with ages of 1888 ▒ 32 and 1979 ▒ 28 Ma (2 ?), respectively. In contrast, phlogopites from emerald-bearing metasomatites display K?Ar ages that spread between 1900 and 2000 Ma with an isochron of 1973 ▒ 20 Ma (2 ?) for CarnaĒba. Generally, the youngest biotite and phlogopite ages occur for specimens where these minerals are chloritized. 40Ar/ 39Ar step heating release spectra are complex but give integrated ages in good agreement with the K?Ar ages. The least disturbed spectrum permits assignment of an age of 2032 ▒ 10 Ma (2 ?)for the first granitic pulse of the emplacement of the Campo Formoso composite pluton. Since in CarnaĒba, deuteric muscovites and chlorite-free phlogopites give similar K?Ar ages, 1979 ▒ 28 and 1973 ▒ 20 Ma (2 ?) respectively, we conclude that emerald mineralization is contemporaneous with the pervasive muscovitization of the granite. The 1979 ▒ 28 Ma (2 ?) age obtained by K?Ar on muscovite represents the best estimate of the CarnaĒba granite cooling age. A model invoking the pervasive alteration of the upper part of the granitic cupola along the pegmatite veins and serpentinites by the muscovitizing fluids is proposed for the formation of emerald-bearing K-metasomatites. The disturbances of 40Ar/ 39Ar release spectra testify to the existence of a hydrothermal heating that overprinted the K?Ar clock of biotite and to a less extent phlogopite. This event is clearly subsequent to the Transamazonian granitization and emerald mineralization and consequently younger than 1973 ▒ 20 Ma. Due to the lack of structural evidences for a Braziliano event (700-500 Ma) in this region, we tentatively propose a Transamazonian age (1900 Ma) for the thermal overprint.

Daisuke Inoue; Ritsu Nomura; Masahiro Kuroda
Recent advances in wireless networks have raised various security threats, among those tracing and denial of service (DoS) attack on mobile devices. Both threats exploit the existence of fixed hardware addresses of mobile devices. This paper provides a transient media access control (MAC) address-TMAC-scheme that enables mobile devices to escape from tracing and DoS attack. The TMAC scheme is based
Staggered TESLA: a multicast authentication scheme resistant to DoS attacks
Qing Li; Wade Trappe
Many techniques for multicast authentication employ the principle of delayed key disclosure. These methods introduce delay in the verification of authentication, employ receiver-side buffers, and consequently are susceptible to denial of service (DoS) attacks. This paper introduces a method to reduce the delay needed to filter forged multicast packets, and consequently mitigates the effects of DoS attacks. Specifically, this paper

Documenting 35 years of land cover change: Lago Cachet Dos drainage, Chile
Friesen, Beverly A.; Nimick, David A.; Mcgrath, Daniel; Cole, Christopher J.; Wilson, Earl M.; Noble, Suzanne M.; Fahey, Mark J.; Leidich, Jonathan; O'Kuinghttons Villena, Jorge I.
The U.S. Geological Survey (USGS) Special Applications Science Center is monitoring temporal changes at the Colonia Glacier and Lago Cachet Dos, Northern Patagonia Icefield of southern Chile. This location is one of the newest international sites in the USGS Global Fiducial Program (GFP)Śa program which provides systematic monitoring of dynamic and environmentally critical areas with high-resolution imagery (http://gfp.usgs.gov/). In 2008, Lago Cachet Dos began experiencing glacial lake outburst floods (GLOFs) during which the entire pool of water (about 200 million cubic meters) rapidly drains from the lake and flows south-southeast through the Colonia Glacier. These catastrophic events cause massive erosion of valley-fill deposits and consequent upstream expansion of Lago Cachet Dos towards Lago Cachet Uno.Ā Panchromatic and multispectral images for 1979, 2007, and 2014 highlight the dramatic changes that have occurred at this site over a 35-year period. The lake was smallest in 1979, when the Colonia Glacier was at its maximum extent during the study period. Between 1979 and 2007, the glacier shrank causing an increase in the surface area of the lake. The size of the lake increased substantially, from 2.98 square kilometers (km2) in 1979 to 4.41 km2Āin 2014, primarily due to erosion of valley-fill deposits upstream of its northern edge by the 15 GLOFs that occurred between April 2008 and February 2014. Ongoing studies of the Colonia Glacier and Lago Cachet Dos are focused on providing real-time monitoring of Lago Cachet Dos lake levels, understanding the history of advances and retreats of the Colonia Glacier, and determining the physical mechanisms and hazards associated with the GLOFs that come from Lago Cachet Dos.

Sedimentation survey of Lago Dos Bocas, Utuado, Puerto Rico, January 2010
Soler-L¾pez, Luis R.
Lago Dos Bocas reservoir was completed in 1942 to provide water for hydroelectric power generation along the northern coast of Puerto Rico. The reservoir had an original storage capacity of 37.50 million cubic meters (Mm3). The dam is located about 9 kilometers (km) northeast of the town of Utuado, immediately downstream of the original confluence of the RĒo Grande de Arecibo and the RĒo Caonillas (fig. 1). The Puerto Rico Electric Power Authority (PREPA) owns and operates the Lago Dos Bocas reservoir, and since 1996, the reservoir has become an essential part of the Puerto Rico Aqueduct and Sewer Authority (PRASA) North Coast Superaqueduct Project. The Superaqueduct is supplied by controlled releases for hydroelectric power generation that replenish the public-supply raw-water intake pool located about 10 km downstream from the Lago Dos Bocas Dam (fig. 1). As of 2005, the Superaqueduct supplies about 4.03 cubic meters per second (m3/s) (348,192 cubic meters per day [m3/d]) of potable water to communities along the northern coast, from Arecibo to the San Juan metropolitan area. Because of the importance of the reservoir to the North Coast Superaqueduct, the U.S. Geological Survey (USGS), in cooperation with PRASA, conducted a sedimentation survey of Lago Dos Bocas in January 2009. The results of this survey were used to estimate the useful life and the firm yield of the reservoir, and evaluate the need to dredge the reservoir.

Function, regulation and pathological roles of the Gab/DOS docking proteins
Since their discovery a little more than a decade ago, the docking proteins of the Gab/DOS family have emerged as important signalling elements in metazoans. Gab/DOS proteins integrate and amplify signals from a wide variety of sources including growth factor, cytokine and antigen receptors as well as cell adhesion molecules. They also contribute to signal diversification by channelling the information from activated receptors into signalling pathways with distinct biological functions. Recent approaches in protein biochemistry and systems biology have revealed that Gab proteins are subject to complex regulation by feed-forward and feedback phosphorylation events as well as protein-protein interactions. Thus, Gab/DOS docking proteins are at the centre of entire signalling subsystems and fulfil an important if not essential role in many physiological processes. Furthermore, aberrant signalling by Gab proteins has been increasingly linked to human diseases from various forms of neoplasia to Alzheimer's disease. In this review, we provide a detailed overview of the structure, effector functions, regulation and evolution of the Gab/DOS family. We also summarize recent findings implicating Gab proteins, in particular the Gab2 isoform, in leukaemia, solid tumours and other human diseases. PMID:19737390

Sedimentation History of Lago Dos Bocas, Puerto Rico, 1942-2005
Soler-L¾pez, Luis R.
The Lago Dos Bocas Dam, located in the municipality of Utuado in north central Puerto Rico, was constructed in 1942 for hydroelectric power generation. The reservoir had an original storage capacity of 37.50 million cubic meters and a drainage area of 440 square kilometers. In 1948, the construction of the Lago Caonillas Dam on the Rio Caonillas branch of Lago Dos Bocas reduced the natural sediment-contributing drainage area to 310 square kilometers; therefore, the Lago Caonillas Dam is considered an effective sediment trap. Sedimentation in Lago Dos Bocas reservoir has reduced the storage capacity from 37.50 million cubic meters in 1942 to 17.26 million cubic meters in 2005, which represents a storage loss of about 54 percent. The long-term annual water-storage capacity loss rate remained nearly constant at about 320,000 cubic meters per year to about 1997. The inter-survey sedimentation rate between 1997 and 1999, however, is higher than the long-term rate at about 1.09 million cubic meters per year. Between 1999 and 2005 the rate is lower than the long-term rate at about 0.13 million cubic meters per year. The Lago Dos Bocas effective sediment-contributing drainage area had an average sediment yield of about 1,400 cubic meters per square kilometer per year between 1942 and 1997. This rate increased substantially by 1999 to about 4,600 cubic meters per square kilometer per year, probably resulting from the historical magnitude floods caused by Hurricane Georges in 1998. Recent data indicate that the Lago Dos Bocas drainage area sediment yield decreased substantially to about 570 cubic meters per square kilometer per year, which is much lower than the 1942-1997 area normalized sedimentation rate of 1,235 cubic meters per square kilometer per year. The impact of Hurricane Georges on the basin sediment yield could have been the cause of this change, since the magnitude of the floods could have nearly depleted the Lago Dos Bocas drainage area of easily erodible and transportable bed sediment. This report summarizes the historical change in water-storage capacity of Lago Dos Bocas between 1942 and 2005.
Qual o Papel da Escola e da MĒdia na ObtenńŃo dos Conhecimentos Astron¶micos?

da Cunha, W. S.; Voelzke, M. R.; Amaral, L. H.
╔ amplamente reconhecido que as pessoas em geral tĻm grande fascĒnio e interesse pela Astronomia. Por outro lado, o conte·do dessa ßrea incluĒdo no ensino formal estß longe de ser abrangente e suficiente para suprir a demanda. Esse interesse permite aperfeińoar a divulgańŃo e o ensino nŃo formal de Astronomia atravķs da mĒdia aliando a adequańŃo do conte·do Ó expectativa das pessoas. A reforma do CurrĒculo Bßsico da Escola P·blica da maioria dos Estados brasileiros tem introduzido Astronomia desde a prķ-escola atķ o Ensino Mķdio. Num estudo realizado com 1180 alunos do Ensino Mķdio de seis escolas estaduais, revelou-se atravķs da aplicańŃo de um formulßrio contendo quest§es que abordavam conhecimentos bßsicos em Astronomia, como foram adquiridos tais conhecimentos e Ó infra-estrutura da escola. Para 66,1% dos entrevistados o professor jß fez alguma apresentańŃo a respeito de Astronomia. O presente estudo revelou tambķm que 54,4% dos alunos entrevistados adquiriram seus conhecimentos astron¶micos na escola, 18,4% atravķs da televisŃo e 27,1% afirmaram que seus conhecimentos foram obtidos atravķs de outros tipos de mĒdia (internet, livros didßticos, filmes e revistas). Embora o estudo revele claramente que hß certo equilĒbrio no meio em que os alunos obtiveram seus conhecimentos astron¶micos, a mĒdia busca nŃo somente sua difusŃo, mas a disponibilizańŃo desse conhecimento de maneira correta, que Ós vezes, nŃo ķ atingido, apresentando conceitos sem fundamentańŃo e incorretos. Por outro lado, no dia-a-dia escolar, ķ comum encontrar professores que vĻm para as aulas com concepń§es prķvias, que podem diferir substancialmente das idķias a serem ensinadas, dificultando o aprendizado de futuros conceitos cientĒficos. Uma avaliańŃo criteriosa, avaliando as dificuldades dos professores em determinar o sentido correto dos conceitos e observando a metodologia que utilizam no ensino, poderß proporcionar uma melhor compreensŃo sobre as concepń§es alternativas, presentes no ensino de Astronomia.

Com o prop¾sito de minimizar algumas dessas deficiĻncias foi realizado um trabalho de pesquisa com a utilizańŃo de questionßrios prķ e p¾s pesquisa, para tanto foi desenvolvido um Curso de ExtensŃo Universitßria para professores da Diretoria de Ensino Regional (DE) que abrange Mauß, RibeirŃo Pires e Rio Grande da Serra (no Estado de SŃo Paulo) com os seguintes objetivos: levantar concepń§es alternativas; subsidiar os professores por meio de palestras, debates e workshops, e verificar o sucesso da aprendizagem ap¾s o curso, adotando-se como referĻncia, para a anßlise dos resultados, os dicionßrios de LĒngua Portuguesa (FERREIRA, 2004) e Enciclopķdico de Astronomia e Astronßutica (MOUR?O, 1995). Portanto, dezesseis quest§es foram aplicadas antes e ap¾s o curso, assim pode-se verificar ap¾s a pesquisa que 100,0% dos professores sabiam os nomes das fases da Lua, 97,0% entenderam que o Sistema Solar ķ composto por oito planetas, 78,1% foram capazes de explicar como ocorre um eclipse lunar, um eclipse solar e um solstĒcio, 72,7% sabiam como explicar a ocorrĻncia das estań§es do ano; 64,5% explicaram corretamente a ocorrĻncia do equin¾cio, 89,7% foram capazes de definir adequadamente o termo cometa; 63,6% definiram aster¾ide, 54,5% meteoro, 58,1% galßxia, e 42,4% planeta. Os resultados obtidos indicam uma aprendizagem significativa por parte dos participantes.

Influence of pre-salt alignments in post-Aptian magmatism in the Cabo Frio High and its surroundings, Santos and Campos basins, SE Brazil: An example of non-plume-related magmatism
NASA Astrophysics Data System (ADS)
Oreiro, Sķrgio Goulart; Cupertino, Josķ Ant¶nio; Szatmari, Peter; Filho, Ant¶nio Thomaz
This study, based on interpretations of 2D and 3D seismic data, onshore satellite data, and offshore seismic mapping and well data, addresses the geological evolution of Late Cretaceous and Early Tertiary magmatism in the offshore Cabo Frio area, at the border between the Santos and Campos basins, SE Brazil. The analysis of the available data set suggests an alternative genesis for this magmatism, different from the classic mantle plume model. Seismic mapping of the main feeder dikes reveals a predominant SE-NW orientation, coincident with the alignment of the Cruzeiro do Sul deformation zone, in which the Cabo Frio High is included. This observation is coherent with the characteristics of the major onshore Precambrian strike-slip faults, which were reactivated during the Cenozoic. The largest offshore volumes of magmatic rocks occur intercalated in the sedimentary section and at the intersections of two fault alignments: a SE-NW, strike-slip fault trend and a SW-NE, normal fault trend, similar to the onshore alkaline bodies of the Pońos de Caldas-Cabo Frio alignment. The possibly reactivated faults (mainly SE-NW transfer faults) could have cut through the whole lithosphere, reached the asthenosphere, and caused partial melting simply by pressure release.
Using satellite images to monitor glacial-lake outburst floods: Lago Cachet Dos drainage, Chile
Friesen, Beverly A.; Cole, Christopher J.; Nimick, David A.; Wilson, Earl M.; Fahey, Mark J.; McGrath, Daniel J.; Leidich, Jonathan
During 2008¢2013, 14 GLOFs were released from Lago Cachet Dos and created environmental and safety concerns for downstream residents and to infrastructure. If GLOFs and the consequent headward erosion continue, the moraine that creates Lago Cachet Uno could be destabilized and breached, and the two lakes could merge. If the two lakes become connected, the volume of future GLOFs likely would be greater and thus cause longer and (or) more extensive flooding downstream. Additional GLOFs from Lago Cachet Dos are expected in the future, and continued environmental monitoring could provide an early warning system as well as scientific information that could increase our understanding of GLOFs and their consequences. GLOFs occur in glaciated areas around the world and remote sensing technologies can allow researchers to better understandŚand potentially predictŚfuture GLOF events.
An alternate hypothesis for the origin of Angra dos Reis - Porphyry, not cumulate
NASA Technical Reports Server (NTRS)
Treiman, A. H.
The Angra dos Reis achondrite is a unique meteorite of potentially great importance for understanding the origins of the solar system and of the terrestrial planets. It is proposed that the meteorite, which consists of megacrysts of Al-Ti augite (fassaite) in skeletal or cellular shapes, olivine, and possibly whitlockite in a fine-grained groundmass of the same materials plus spinel, is a porphyritic igneous rock modified by metamorphism. In this interpretation, the megacrysts represent cellular-textured phenocrysts, and the fine-grain groundmass represents crystallized or devitrified magma. Phase equilibria suggest that Angra dos Reis-like compositions could grow phenocrysts of fassaite pyroxene, olivine, and whitlockite. These same compositions could crystallize, without crystal sorting or accumulation, to an almost monomineralic fassaite pyroxenite.

Sm-Nd-Pu timepieces in the Angra DOS Reis meteorite
G. W. Lugmair; K. Marti
Isotope ratios and age estimations are presented for the ultramafic pyroxenite Angra dos Reis meteorite. A pyroxene-phosphate internal isochron age of 4.55 plus or minus 0.04 eons was obtained, in agreement with reported Pb-Pb ages. It is suggested that Sm-146 decay led to an increase in the ratio of Nd-142 to Nd-144 in pyroxene, which is greater than the ratio

Reducing delay and enhancing DoS resistance in multicast authentication through multigrade security
Qing Li; Wade Trappe
Many techniques for multicast authentication employ the principle of delayed key disclosure. These methods introduce delay in authentication, employ receiver-side buffers, and are susceptible to denial-of-service (DoS) attacks. Delayed key disclosure schemes have a binary concept of authentication and do not incorporate any notion of partial trust. This paper introduces staggered timed efficient stream loss-tolerant authentication (TESLA), a method for
FlexyDos3D: a deformable anthropomorphic 3D radiation dosimeter: radiation properties.
De Deene, Y; Skyt, P S; Hil, R; Booth, J T
Three dimensional radiation dosimetry has received growing interest with the implementation of highly conformal radiotherapy treatments. The radiotherapy community faces new challenges with the commissioning of image guided and image gated radiotherapy treatments (IGRT) and deformable image registration software.A new three dimensional anthropomorphically shaped flexible dosimeter, further called 'FlexyDos3D', has been constructed and a new fast optical scanning method has been implemented that enables scanning of irregular shaped dosimeters. The FlexyDos3D phantom can be actuated and deformed during the actual treatment. FlexyDos3D offers the additional advantage that it is easy to fabricate, is non-toxic and can be molded in an arbitrary shape with high geometrical precision.The dosimeter formulation has been optimized in terms of dose sensitivity. The influence of the casting material and oxygen concentration has also been investigated. The radiophysical properties of this new dosimeter are discussed including stability, spatial integrity, temperature dependence of the dosimeter during radiation, readout and storage, dose rate dependence and tissue equivalence.

DoS detection in IEEE 802.11 with the presence of hidden nodes.
Soryal, Joseph; Liu, Xijie; Saadawi, Tarek
The paper presents a novel technique to detect Denial of Service (DoS) attacks applied by misbehaving nodes in wireless networks with the presence of hidden nodes employing the widely used IEEE 802.11 Distributed Coordination Function (DCF) protocols described in the IEEE standard [1]. Attacker nodes alter the IEEE 802.11 DCF firmware to illicitly capture the channel via elevating the probability of the average number of packets transmitted successfully using up the bandwidth share of the innocent nodes that follow the protocol standards. We obtained the theoretical network throughput by solving two-dimensional Markov Chain model as described by Bianchi [2], and Liu and Saadawi [3] to determine the channel capacity. We validated the results obtained via the theoretical computations with the results obtained by OPNET simulator [4] to define the baseline for the average attainable throughput in the channel under standard conditions where all nodes follow the standards. The main goal of the DoS attacker is to prevent the innocent nodes from accessing the channel and by capturing the channel's bandwidth. In addition, the attacker strives to appear as an innocent node that follows the standards. The protocol resides in every node to enable each node to police other nodes in its immediate wireless coverage area. All innocent nodes are able to detect and identify the DoS attacker in its wireless coverage area. We applied the protocol to two Physical Layer technologies: Direct Sequence Spread Spectrum (DSSS) and Frequency Hopping Spread Spectrum (FHSS) and the results are presented to validate the algorithm.

Age and isotopic relationships among the angrites Lewis Cliff 86010 and Angra dos Reis
Lugmair, G.W. (Univ. of California, San Diego, La Jolla (United States)); Galer, S.J.G. (Univ. of California, San Diego, La Jolla (United States) Max-Planck-Inst. fuer Chemie, Mainz (West Germany))
Results of a wide-ranging isotopic investigation of the unique Antarctican angrite LEW-86010 (LEW) are presented, together with a reassessment of the type angrite Angra dos Reis (ADOR). The principal objectives of this study are to obtain precise radiometric ages, initial Sr isotopic compositions, and to search for the erstwhile presence of the short-lived nuclei {sup 146}Sm and {sup 26}Al via their daughter products. The isotopic compositions of Sm, U, Ca, and Ti were also measured. This allows a detailed appraisal to be made of the relations between, and the genealogy of, these two angrites.

Reproductive Dynamics of Sterna hirundinacea Lesson, 1831 in Ilha dos Cardos, Santa Catarina, Brazil
Fracasso, Hķlio Augusto Alves; Branco, Joaquim Olinto; Efe, Mßrcio Amorim
In this work, we intend to describe the reproductive dynamics of Sterna hirundinacea in an island from South Brazil. We studied the reproductive biology of this species in its natural environment and provide data on their growth, survival, and reproductive success in Ilha dos Cardos, Santa Catarina, South Brazil. Samplings were carried out daily on the island throughout the reproductive seasons of 2003, 2005, and 2006 and the different stages of development of the chicks were characterized according to age, length of the beak, and plumage characteristics. We provide a basic equation Lm = 167.91?(1 ? e?0.062t?(?0.23)) to determine the approximate age of individuals using their body mass. The main cause of chick mortality on the island was natural (63.17% in 2003, 81.41% in 2005, and 79.96% in 2006), whereas predation contributed to mortality in a proportion of 38.83% in 2003, 18.59% in 2005, and 20.04% in 2006. The absence in the area of the chicks' main predator, Kelp gull (Larus dominicanus), the large number of chicks that reached the final stages of development, and their reproductive success demonstrate that Ilha dos Cardos is an important breeding site for the species in southern Brazil.

Quality control and assurance for validation of DOS/I measurements
NASA Astrophysics Data System (ADS)
Cerussi, Albert; Durkin, Amanda; Kwong, Richard; Quang, Timothy; Hill, Brian; Tromberg, Bruce J.; MacKinnon, Nick; Mantulin, William W.
Ongoing multi-center clinical trials are crucial for Biophotonics to gain acceptance in medical imaging. In these trials, quality control (QC) and assurance (QA) are key to success and provide "data insurance". Quality control and assurance deal with standardization, validation, and compliance of procedures, materials and instrumentation. Specifically, QC/QA involves systematic assessment of testing materials, instrumentation performance, standard operating procedures, data logging, analysis, and reporting. QC and QA are important for FDA accreditation and acceptance by the clinical community. Our Biophotonics research in the Network for Translational Research in Optical Imaging (NTROI) program for breast cancer characterization focuses on QA/QC issues primarily related to the broadband Diffuse Optical Spectroscopy and Imaging (DOS/I) instrumentation, because this is an emerging technology with limited standardized QC/QA in place. In the multi-center trial environment, we implement QA/QC procedures: 1. Standardize and validate calibration standards and procedures. (DOS/I technology requires both frequency domain and spectral calibration procedures using tissue simulating phantoms and reflectance standards, respectively.) 2. Standardize and validate data acquisition, processing and visualization (optimize instrument software-EZDOS; centralize data processing) 3. Monitor, catalog and maintain instrument performance (document performance; modularize maintenance; integrate new technology) 4. Standardize and coordinate trial data entry (from individual sites) into centralized database 5. Monitor, audit and communicate all research procedures (database, teleconferences, training sessions) between participants ensuring "calibration". This manuscript describes our ongoing efforts, successes and challenges implementing these strategies.
Dosimetry and Vibration measurements in BIOLAB and EMCS (Dos-ViBE)

Space irradiation and vibrations in even small dosages can impact biological experiments and have not yet been measured in the biological payloads of the Columbus module at the Interna-tional Space Station (ISS). Installing active dosimeters and accelerometers in the Experiment Containers (EC) of Biolab and the European Modular Cultivation System (EMCS), to sur-vey in-situ the radiation and vibrations in these facilities, should be performed to serve as a reference of the space conditions to future experiments. To monitor the radiation field, the space radiation should be measured with an active dosime-ter inside the Multi-User-Facilities, as close to the actual shielding conditions of the biological experiments as possible. To measure the full spectrum of vibration frequencies, several instru-ments with different measurement ranges and sensitivity should be combined. The radiation and vibrations should be measured simultaneously in Biolab and EMCS to compare their radiation shielding and sensitivities to vibrations from the ISS. The radiation could also be measured with passive dosimeters. On the one hand this would be a back-up to the active dosimeter and on the other hand it would provide additional data since the passive dosimeters can give additional information on the radiation LET spectrum. As a response to ESA's Announcement of Opportunity (ILSRA-2009), a joint experiment in Biolab and EMCS, entitled Dos-ViBE, was proposed by the co-authors.

Raja, K Nirmal; Beno, M Marsaline
Wireless sensor networks are generally deployed for collecting data from various environments. Several applications specific sensor network cryptography algorithms have been proposed in research. However WSN's has many constrictions, including low computation capability, less memory, limited energy resources, vulnerability to physical capture, which enforce unique security challenges needs to make a lot of improvements. This paper presents a novel security mechanism and algorithm for wireless sensor network security and also an application of this algorithm. The proposed scheme is given to strong authentication against Denial of Service Attacks (DOS). The scheme is simulated using network simulator2 (NS2). Then this scheme is analyzed based on the network packet delivery ratio and found that throughput has improved. PMID:25106827
An MS-DOS-based program for analyzing plutonium gamma-ray spectra
Ruhter, W.D.; Buckley, W.M.
A plutonium gamma-ray analysis system that operates on MS-DOS-based computers has been developed for the International Atomic Energy Agency (IAEA) to perform in-field analysis of plutonium gamma-ray spectra for plutonium isotopics. The program titled IAEAPU consists of three separate applications: a data-transfer application for transferring spectral data from a CICERO multichannel analyzer to a binary data file, a data-analysis application to analyze plutonium gamma-ray spectra, for plutonium isotopic ratios and weight percents of total plutonium, and a data-quality assurance application to check spectral data for proper data-acquisition setup and performance. Volume 3 contains the software listings for these applications.
The Secret List of Dos and Don'ts for Filmmaking
NASA Astrophysics Data System (ADS)
Kramer, N.
Science is a massive black box to billions of people who walk the streets. However, the process of filmmaking can be equally as mystifying. As with the development of many scientific experiments, the process starts on a napkin at a restaurantģbut then what? The road to scientific publication is propelled by a canonical list of several dos and don't that fit most situations. An equally useful list exists for up-and-coming producers. The list streamlines efforts, optimizes your use of the tools at your fingertips and enhances impact. Many fundamentals can be learned from books, but during this talk we will project and discuss several examples of best practices, from honing a story, to identifying audience appeal, filming, editing and the secrets of inexpensively acquiring expert help. Whether your goal is a two-minute webisode or a 90 minute documentary, these time-tested practices, with a little awareness, can give life to your films.;
Structural Insight into the Heme-based Redox Sensing by DosS from Mycobacterium tuberculosis*S?
Cho, Ha Yeon; Cho, Hyo Je; Kim, Young Min; Oh, Jeong Il; Kang, Beom Sik
Mycobacterium tuberculosis is thought to undergo transformation into its non-replicating persistence state under the influence of hypoxia or nitric oxide (NO). This transformation is thought to be mediated via two sensor histidine kinases, DosS and DosT, each of which contains two GAF domains that are responsible for detecting oxygen tension. In this study we determined the crystal structures of the first GAF domain (GAF-A) of DosS, which shows an interaction with a heme. A b-type heme was embedded in a hydrophobic cavity of the GAF-A domain and was roughly perpendicular to the ?-sheet of the GAF domain. The heme iron was liganded by His-149 at the proximal heme axial position. The iron, in the oxidized form, was six-coordinated with a water molecule at the distal position. Upon reduction, the iron, in ferrous form, was five-coordinated, and when the GAF domain was exposed to atmospheric O2, the ferrous form was oxidized to generate the Met form rather than a ferrous O2-bound form. Because the heme is isolated inside the GAF domain, its accessibility is restricted. However, a defined hydrogen bond network found at the heme site could accelerate the electron transferability and would explain why DosS was unable to bind O2. Flavin nucleotides were shown to reduce the heme iron of DosS while NADH was unable to do so. These results suggest that DosS is a redox sensor and detects hypoxic conditions by its reduction.

[Temporary and permanent breeding sites for Biomphalaria in JaboatŃo dos Guararapes, PE].
Souza, Marco Ant¶nio Andrade de; Barbosa, Ver¶nica Santos; Wanderlei, Tereza Neuma Guedes; Barbosa, Constanńa Sim§es
A malacological survey of permanent and temporary breeding sites was conducted in the Piedade neighborhood of JaboatŃo dos Guararapes, Pernambuco, between November 2006 and November 2007, with the aim of determining the malacological fauna at this locality, along with the potential for Schistosomiasis mansoni transmission. In addition to Biomphalaria glabrata (Say, 1818), the molluscs Drepanotrema cimex (Moricand, 1837), Pomacea sp and Melanoides tuberculatus (Muller, 1774) were collected. Among the specimens of Biomphalaria glabrata that were collected, 1,490 were found alive, and 74 (5%) were positive for Schistosoma mansoni. The largest numbers of molluscs collected, and all of the specimens that were positive for Schistosoma mansoni, were collected during the annual rainy season. The presence of larvae of other trematodes infecting the Biomphalaria glabrata molluscs was also observed. These trematodes were from the families Strigeidae and Diplostomatidae and, at first sight, they presented morphology that could lead to confusion with Schistosoma mansoni cercariae. Thus, knowledge of these trematodes becomes essential for the differential diagnosis of the etiological agent for schistosomiasis. PMID:18719804

[Habitat heterogeneity, richness and structure of assemblages of dung beetles (Scarabaeidae: Scarabaeinae) in areas of cerrado in the Chapada dos Parecis, Mato Grosso state, Brazil].
Silva, Ricardo J da; Diniz, Soraia; Vaz-de-Mello, Fernando Z
Ecological theory of habitat heterogeneity and limited niche-similarity assumes that more heterogeneous environments provide a greater amount and diversity of resources than simple environments, resulting in a greater diversity of species. This study aimed to evaluate the effect of the habitat heterogeneity on the richness of dung beetles and to examine the spatial patterns of assemblage structure in relation to patterns of habitat heterogeneity. Dung beetles were collected using pitfall traps without bait in 30 points distributed in an area of cerrado sensu lato, in the region of Tangarß da Serra, MT, Brazil, including areas of cerrado sensu stricto, campo sujo, cerradŃo and gallery forest. A total of 1,291 dung beetles were collected, distributed in 16 genera and 29 species. Overall habitat heterogeneity exerted a negative effect on patterns of dung beetles richness. Higher levels of species richness were observed in areas of cerrado campo sujo, while the areas of gallery forest were the most species poor. Regarding assembly structure, it was found that the dung beetles were separated into two major groups, one formed by the presence of specialized species in forest areas and other composed of species that occurred predominantly in cerrado. In conclusion, it was found that habitat complexity influenced the distribution of dung beetles, but the level of turnover in species composition along the heterogeneity gradient was relatively weak.

Rare earth elements in Angra dos Reis and Lewis Cliff 86010, two meteorites with similar but distinct magma evolutions
NASA Technical Reports Server (NTRS)
Crozaz, Ghislaine; Mckay, Gordon
Data are presented on ion microprobe measurements of REE and selected trace element abundances in individual grains of merrillite, fassaite, olivine, kirschsteinite, and plagioclase of Lewis Cliff 86010 (LEW 86010) meteorite and in merrillite and fassaite grains of Angra dos Reis (ADOR). Results show a close relationship between the two meteorites and support a magmatic origin for LEW 86010. However, the measurements indicate that, despite numerous common characteristics, the two meteorites must have been produced in separate magmatic events involving similar but distinct processes and parent melts.

Kinetics and products from reaction of Cl radicals with dioctyl sebacate (DOS) particles in O(2): a model for radical-initiated oxidation of organic aerosols.
Hearn, John D; Renbaum, Lindsay H; Wang, Xi; Smith, Geoffrey D
The reaction of Cl radicals with bis (2-ethylhexyl) sebacate (also known as dioctyl sebacate, DOS) particles in the presence of O(2) is studied as a model of radical-initiated oxidation of organic aerosols. The uptake coefficient as measured from the rate of loss of DOS is gamma(DOS) = 1.7 (+/-0.3) indicating that a radical chain is operative. It is observed that nearly all of the detected products, accounting for 86% (+/-12%) of the reacted DOS, remain in the particles indicating that they are not efficiently volatilized. Correspondingly, the particles do not decrease in volume even after 60% of the DOS has reacted; upon further reaction the volume does decrease by up to 20%. Additionally, the mass of a DOS film increases with reaction indicating that the density increases. The two primary products identified are the ketone (38 +/- 10% yield) and alcohol (14 +/- 4% yield) resulting from reactions of alkylperoxy radicals originating from DOS oxidation. The fact that the ketone/alcohol ratio is >1 implies that the Russell mechanism, the typical fate of alkylperoxy radicals in liquids whereby both a ketone and an alcohol are generated, is not the only source of ketones. In fact, the ketone yield demonstrates a Langmuir-Hinshelwood type dependence on the O(2) concentration indicating that 44% (+/-8%) of the ketone is created from the reaction of alkoxy radicals with O(2) at the surface of the particles (at 20% O(2)). While this is a common reaction in the gas phase, it is generally not considered to occur in organic solvents. Furthermore, the appearance of gas-phase H(2)O(2) suggests that peroxy radicals react to form two ketones and H(2)O(2)via the Bennett and Summers mechanism. The absence of aldehyde products, both in the gas phase and in the particles, indicates that beta-scission of the alkoxy radicals is not significant. The results of this study suggest that organic aerosols in the troposphere are efficiently oxidized by gas-phase radicals but that their chemical transformation does not lead to their removal through volatilization.

DRK/DOS/SOS converge with Crk/Mbc/dCed-12 to activate Rac1 during glial engulfment of axonal debris
Lu, Tsai-Yi; Doherty, Johnna; Freeman, Marc R.
Nervous system injury or disease leads to activation of glia, which govern postinjury responses in the nervous system. Axonal injury in Drosophila results in transcriptional up-regulation of the glial engulfment receptor Draper; there is extension of glial membranes to the injury site (termed activation), and then axonal debris is internalized and degraded. Loss of the small GTPase Rac1 from glia completely suppresses glial responses to injury, but upstream activators remain poorly defined. Loss of the Rac guanine nucleotide exchange factor (GEF) Crk/myoblast city (Mbc)/dCed-12 has no effect on glial activation, but blocks internalization and degradation of debris. Here we show that the signaling molecules downstream of receptor kinase (DRK) and daughter of sevenless (DOS) (mammalian homologs, Grb2 and Gab2, respectively) and the GEF son of sevenless (SOS) (mammalian homolog, mSOS) are required for efficient activation of glia after axotomy and internalization/degradation of axonal debris. At the earliest steps of glial activation, DRK/DOS/SOS function in a partially redundant manner with Crk/Mbc/dCed-12, with blockade of both complexes strongly suppressing all glial responses, similar to loss of Rac1. This work identifies DRK/DOS/SOS as the upstream Rac GEF complex required for glial responses to axonal injury, and demonstrates a critical requirement for multiple GEFs in efficient glial activation after injury and internalization/degradation of axonal debris.

Geochemistry and petrogenesis of the Mesoarchean granites from the CanaŃ dos Carajßs area, Carajßs Province, Brazil: Implications for the origin of Archean granites
NASA Astrophysics Data System (ADS)
Feio, G. R. L.; Dall'Agnol, R.
Four Mesoarchean (2.93 to 2.83 Ga) granite units, which encompass the CanaŃ dos Carajßs, Bom Jesus, CruzadŃo and Serra Dourada granites, were recognized in the CanaŃ dos Carajßs area of the Archean Carajßs Province. The Mesoarchean units are composed dominantly of biotite leucomonzogranites. They are compared with the Neoarchean Planalto suite (2.73 Ga) which encompasses biotite-hornblende monzogranites to syenogranites. The CanaŃ dos Carajßs, Bom Jesus and the variety of the CruzadŃo granite with higher (La/Yb)N are geochemically more akin to the calc-alkaline granites, whereas the other varieties of the CruzadŃo granite are transitional between calc-alkaline and alkaline granites. The Serra Dourada granite has an ambiguous geochemical character with some features similar to those of calc-alkaline granites and other peraluminous granites. The Planalto granites have ferroan character, are similar geochemically to reduced A-type granites and show a strong geochemical contrast with the Mesoarchean studied granites. The Mesoarchean granites described in the CanaŃ dos Carajßs area are geochemically distinct to those of the Rio Maria domain of the Carajßs Province. The CanaŃ dos Carajßs and Bom Jesus granites are similar to the high-Ca granites, whereas the CruzadŃo and Serra Dourada are more akin to the low-CaO granites of the Yilgarn craton. The geochemical characteristics of the Mesoarchean studied granites approach those of the biotite granite group of Dharwar but the latter are enriched in HFSE and HREE compared to the CanaŃ dos Carajßs granites. The Neoarchean Planalto suite granite has no counterpart in the Mesoarchean Rio Maria domain of the Carajßs Province, neither in the Yilgarn and Dharwar cratons. Geochemical modeling suggests that partial melting of a source similar in composition to an Archean basaltic andesite of the Carajßs Province could give origin to the Bom Jesus and CruzadŃo granites. In the case of the Bom Jesus granite the residue of melting contained, in similar proportions, plagioclase, clinopyroxene, amphibole, and garnet, with subordinate ilmenite. The variations in (La/Yb)N and Sr/Y of the CruzadŃo granite are controlled by changes in the residual melting phases. Garnet and amphibole are abundant in the residue of the variety with higher (La/Yb)N, whereas in the rocks with moderate to lower (La/Yb)N garnet is absent, magnetite appears in the residue and amphibole initially increases but is replaced by orthopyroxene in the rocks with the lowest (La/Yb)N. In the CanaŃ dos Carajßs and Serra Dourada granites garnet was probably an absent phase in the residue of melting and the influence of amphibole was also apparently limited. A crustal environment and a variable pressure from 10 to 7-8 kbar are estimated for the generation of the granite magmas. The Bom Jesus and CruzadŃo granites of Carajßs derived from basaltic andesite sources and not of TTG and their geochemical contrasts can be explained by variation in the pressure of melting. The sources of Archean granite magmas are more diversified and could be more mafic than generally admitted.

Catalytic enhancement of the heme-based oxygen-sensing phosphodiesterase EcDOS by hydrogen sulfide is caused by changes in heme coordination structure.

EcDOS is a heme-based O2-sensing phosphodiesterase in which O2 binding to the heme iron complex in the N-terminal domain substantially enhances catalysis toward cyclic-di-GMP, which occurs in the C-terminal domain. Here, we found that hydrogen sulfide enhances the catalytic activity of full-length EcDOS, possibly owing to the admixture of 6-coordinated heme Fe(III)-SH(-) and Fe(II)-O2 complexes generated during the reaction. Alanine substitution at Met95, the axial ligand for the heme Fe(II) complex, converted the heme Fe(III) complex into the heme Fe(III)-SH(-) complex, but the addition of Na2S did not further reduce it to the heme Fe(II) complex of the Met95Ala mutant, and no subsequent formation of the heme Fe(II)-O2 complex was observed. In contrast, a Met95His mutant formed a stable heme Fe(II)-O2 complex in response to the same treatment. An Arg97Glu mutant, containing a glutamate substitution at the amino acid that interacts with O2 in the heme Fe(II)-O2 complex, formed a stable heme Fe(II) complex in response to Na2S, but this complex failed to bind O2. Interestingly, the addition of Na2S promoted formation of verdoheme (oxygen-incorporated, modified protoporphyrin IX) in an Arg97Ile mutant. Catalytic enhancement by Na2S was similar for Met95 mutants and the wild type, but significantly lower for the Arg97 mutants. Thus, this study shows the first isolation of spectrometrically separated, stable heme Fe(III)-SH(-), heme Fe(II) and heme Fe(II)-O2 complexes of full-length EcDOS with Na2S, and confirms that external-ligand-bound, 6-coordinated heme Fe(III)-SH(-) or heme Fe(II)-O2 complexes critically contribute to the Na2S-induced catalytic enhancement of EcDOS.

Aspects of the ecology of phlebotomines (Diptera: Psychodidae: Phlebotominae) in an area of cutaneous leishmaniasis occurrence, municipality of Angra dos Reis, coast of Rio de Janeiro State, Brazil.
Aguiar, Gustavo Marins de; de Azevedo, Alfredo Carlos Rodrigues; Medeiros, Wagner Muniz de; Alves, JoŃo Ricardo Carreira; Rendeiro, Vanessa
Over a complete two-year period, phlebotomine specimens were caught in an area of cutaneous leishmaniasis occurrence in the municipality of Angra dos Reis. A manual suction tube was used to catch phlebotomines on house walls, and also light traps in domestic and peridomestic settings and in the forest. This yielded 14,170 specimens of 13 species: two in the genus Brumptomyia and eleven in the genus Lutzomyia. L. intermedia predominantly in domestic and peridomestic settings, with little presence in the forest, with the same trend being found in relation to L. migonei, thus proving that these species have adapted to the human environment. L. fischeri appeared to be eclectic regarding location, but was seen to be proportionally more endophilic. L. intermedia and L. migonei were more numerous in peridomestic settings, throughout the year, while L. fischeri was more numerous in domestic settings except in March, April, May and September. From the prevalence of L. intermedia, its proven anthropophily and findings of this species naturally infected with Leishmania (Viannia) braziliensis, it can be incriminated as the main vector for this agent of cutaneous leishmaniasis in the study area, especially in the peridomestic environment. L. fischeri may be a coadjuvant in carrying the parasite. PMID:24626417

The Residue Threonine 82 of DevR (DosR) Is Essential for DevR Activation and Function in Mycobacterium tuberculosis Despite Its Atypical Location?
Gautam, Uma Shankar; Sikri, Kriti; Tyagi, Jaya Sivaswami
The DevR (DosR) response regulator initiates the bacterial adaptive response to a variety of signals, including hypoxia in in vitro models of dormancy. Its receiver domain works as a phosphorylation-mediated switch to activate the DNA binding property of its output domain. Receiver domains are characterized by the presence of several highly conserved residues, and these sequence features correlate with structure and hence function. In response regulators, interaction of phosphorylated aspartic acid at the active site with the conserved threonine is believed to be crucial for phosphorylation-mediated conformational change. DevR contains all the conserved residues, but the structure of its receiver domain in the unphosphorylated protein is strikingly different, and key threonine (T82), tyrosine (Y101), and lysine (K104) residues are placed uncharacteristically far from the D54 phosphorylation site. In view of the atypical location of T82 in DevR, the present study aimed to examine the importance of this residue in the activation mechanism. Mycobacterium tuberculosis expressing a DevR T82A mutant protein is defective in autoregulation and supports hypoxic induction of the DevR regulon only very weakly. These defects are ascribed to slow and partial phosphorylation and the failure of T82A mutant protein to bind cooperatively with DNA. Our results indicate that the T82 residue is crucial in implementing conformational changes in DevR that are essential for cooperative binding and for subsequent gene activation. We propose that the function of the T82 residue in the activation mechanism of DevR is conserved in spite of the unusual architecture of its receiver domain. PMID:21764934

Geochronological data from TTG-type rock associations of the Arroio dos Ratos Complex and implications for crustal evolution of southernmost Brazil in Paleoproterozoic times

U-Pb isotope analyses by LA-MC-ICPMS (Laser Ablation - Multi Collector - Inductively Coupled Plasma Mass Spectrometry) in zircon crystals from metatonalites, tonalites and granodiorite gneiss from the Arroio dos Ratos Complex (ARC) early magmatism in southernmost Brazil are presented. The ARC is located in the eastern portion of the Sul-rio-grandense Shield, occurring as septa and roof pendants on granitoids emplaced along the Southern Brazilian Shear Belt (SBSB). The SBSB corresponds to a translithospheric structure composed of several anastomosed shear zones of dominantly transcurrent kinematics whose syntectonic magmatism, of Neoproterozoic age, is characteristic of post-collisional environments. The studied rocks comprise TTG-type associations with coeval mafic magmatism, deformed and metamorphosed within a ductile shear zone. Zircon crystals obtained from six samples are interpreted as igneous given that the crystals are subhedral to euhedral, bipyramidal, with concentric zonation, have ratios Th/U between 0.13 and 0.81 and have restricted evidence of overgrowth. The oldest Association 1 (A1) has structures compatible with recrystallization under conditions of high temperature and an igneous age of 2148 ▒ 33 Ma, obtained in a metatonalite. The rocks of Association 2 (A2) have similar compositions, although with a more significant coeval mafic fraction. They are intrusive into A1 and also show high-temperature recrystallization features. However, they are less deformed and partly preserve their primary, igneous fabric. The igneous ages obtained from two A2 tonalites are 2150 ▒ 28 Ma and 2136 ▒ 27 Ma. Association 3 (A3) is represented by tonalitic to granodioritic gneisses whose structure, composition and metamorphic features are similar to those of A1 rocks, except for the absence of coeval mafic magmas in the former. Local features resulting from partial melting are present in A3 rocks. Three samples from A3 were dated. A tonalitic gneiss gives igneous age of 2099 ▒ 10 Ma and two granodioritic gneisses give igneous ages of 2081 ▒ 7 Ma and 2077 ▒ 13 Ma. Restricted to A1, inheritance is represented by one subhedral, zoned, gently rounded zircon crystal interpreted as igneous, of 2732 ▒ 40 Ma (207Pb/206Pb age), with discordance of 9% and 232Th/238U ratio of 1.17. A single Neoproteozoic metamorphic date value was obtained from the rim of a zircon crystal of Paleoproterozoic core. The age of 635 ▒ 6 Ma (207Pb/206Pb age), with Th/U ratio < 0.1 and 1% discordance, is interpreted as compatible with adjacent SBSB magmatism. The three associations are interpreted to represent the record of successive magmatic pulses that mark the evolution of a Paleoproterozoic continental magmatic arc. In the study area, these magmatic arc associations represent relict areas partly reworked and relatively well-preserved from Neoproterozoic tectono-magmatic post-collisional events during the construction of the Southern Brazilian Shear Belt.

Precipitation inhibitor squeeze treatments have been performed in the last 5 years in the Namorado field to avoid barium sulfate and strontium sulfate scaling in the producing tubing. This paper describes the laboratory tests conducted to select inhibitor and to simulate the squeeze operation in porous media. Based on these tests a polyacrylic acid product was used in the squeeze operations. The squeeze operation design is described as well as the strategy for analytical monitoring of the produced waters to select the wells with high precipitation potential for the prevention treatment. This paper describes the occurrence of spherical precipitated material (with morphology similar to ooids formed in natural environments) at the bottom of the well NA-C. The analysis of the ooids, associated with the production parameters, allowed the determination of the effectiveness of the squeeze treatment and the understanding of the precipitation mechanisms.

Although astronomy is considered one of the older sciences of humanity and that the understanding of its concepts has brought tremendous advances to Science and therefore, to society, it is observed that a significant portion of people live outside of this kind of knowledge. According to the ParŌmetros Curriculares Nacionais for basic education, it is the school responsibility the dissemination of scientifically correct concepts, including those related to astronomy. Concerning this issue, we present a survey of 140 students of ninth grade of elementary school and 120 third-grade high-school students from four schools in the region of Passo Fundo/RS. We sought to determine, through a questionnaire consisting of open and multiple choice questions, the knowledge of this group of students about the basic terms and astronomical phenomena, and also verify that the hit rate increases as they advance through the different and progressive grades of primary and secondary education. Overall, the results show that the teaching of astronomy in basic education is facing problems. Of the 20 issues investigated, in 17 the indicators are similar in the correct answers given by students for elementary and middle school, revealing that many misconceptions still remain along basic education. This demonstrates that such issues are not - or are rarely - covered during these two school levels. Thus, we conclude that the discussion of concepts related to astronomy should receive greater emphasis on approaching different subjects, requiring a national action in support of their teaching. It is believed that a national action should be supported by a triple pillar of collective actors: the scientific community, semi-professional astronomy community and the school community. Finally, this pillar would be the basis for future discussions related to the performance of these protagonists as a means to promote active changes in the curricular structure, providing, in more effective ways, the learning of astronomy in basic education. Embora a astronomia seja considerada uma das ciĻncias mais antigas da humanidade e ainda que a compreensŃo de seus conceitos tenha trazido enormes avanńos para a CiĻncia e, consequentemente, para a sociedade, observa-se que uma parcela significativa de pessoas encontra-se Ó margem desses conhecimentos. De acordo com os ParŌmetros Curriculares Nacionais para a EducańŃo Bßsica, cabe Ó escola a difusŃo dos conceitos cientificamente corretos, entre eles os relacionados Ó ßrea de astronomia. Pertinente a essa questŃo, apresenta-se uma pesquisa realizada com 140 estudantes do nono ano do ensino fundamental e com 120 estudantes da terceira sķrie do ensino mķdio de quatro escolas da regiŃo de Passo Fundo/RS. Buscou-se averiguar, por meio de um questionßrio composto de quest§es abertas e de m·ltipla escolha, o conhecimento desse grupo de estudantes acerca de termos e fen¶menos astron¶micos bßsicos e, tambķm, verificar se o Ēndice de acertos cresce Ó medida que eles avanńam nas diferentes e gradativas sķries dos ensinos fundamental e mķdio. De modo geral, os resultados apresentados demonstram que o ensino de astronomia na educańŃo bßsica enfrenta deficiĻncias. Das 20 quest§es investigadas, em 17 os Ēndices de acertos sŃo semelhantes nas respostas dadas por estudantes de nĒvel fundamental e mķdio, revelando que muitas concepń§es equivocadas permanecem ao longo da educańŃo bßsica. Isso evidencia que tais temas nŃo sŃo ¢ ou sŃo pouco ¢ abordados durante esses dois nĒveis de escolarizańŃo. Assim, conclui-se que a discussŃo dos conceitos relacionados com a astronomia deve receber maior Ļnfase na abordagem dos diferentes conte·dos, sendo necessßria uma ańŃo nacional em prol do seu ensino. Acredita-se que essa ańŃo nacional deve estar apoiada em um pilar triplo de atores coletivos: comunidade cientĒfica, comunidade astron¶mica semiprofissional e comunidade escolar. Por fim, esse pilar seria a base para futuras discuss§es relacionadas Ó atuańŃo dessas instŌncias como meio
Impact of natural climate change and historical land use on vegetation cover and geomorphological process dynamics in the Serra dos ėrgŃos mountain range in Rio de Janeiro State, Brazil
NASA Astrophysics Data System (ADS)
Nehren, U.; Sattler, D.; Heinrich, J.
The Serra dos ėrgŃos mountain range in the hinterland of Rio de Janeiro contains extensive remnants of the Atlantic Forest (Mata AtlŌntica) biome, which once covered about 1.5 million km▓ from Northeast to South Brazil and further inland to Paraguay and Argentina. As a result of historical deforestation and recent land use intensification processes today only 5 to 8% of the original Atlantic Forest remains. Despite the dramatic habitat loss and a high degree of forest fragmentation, the remnants are among the EarthÆs most diverse habitats in terms of species richness. Furthermore, they are characterized by a high level of endemism. Therefore, the biome is considered a "hotspot of biodiversity". In the last years many efforts have been taken to investigate the Mata AtlŌntica biome in different spatial and time scales and from different scientific perspectives. We are working in the Atlantic Forest of Rio de Janeiro since 2004 and focus in our research particularly on Quaternary landscape evolution and landscape history. By means of landscape and soil archives we reconstruct changes in the landscape system, which are mainly the result of Quaternary climate variability, young tectonic uplift and human impact. The findings throw light on paleoecological conditions in the Late Quaternary and the impact of pre-colonial and colonial land use practices on these landscapes. In this context, a main focus is set on climate and human-driven changes of the vegetation cover and its consequences for the geomorphological process dynamics, in particular erosion and sedimentation processes. Research methods include geomorphological field studies, interpretation of satellite images, physical and chemical sediment and soil analyses as well as relative and absolute dating (Feo/Fed ratio and 14C dating). For the Late Quaternary landscape evolution, the findings are compared with results from paleoclimatic and paloecological investigations in Southeast and South Brazil using other dating techniques, such as pollen analysis. The impact of early civilizations on deforestation, forest fragmentation and geomorphological process dynamics is estimated on the basis of archaeological and anthropological findings. Furthermore, historical sources, such as written documents, maps, paintings and photographs, were collected and analysed to get a more detailed picture of the younger landscape history. As a result we present a landscape genetic model for the Late Quaternary in the Serra dos ėrgŃos mountain range and the Guanabara Basin. Based on a functional analysis of the natural process dynamics we reconstruct the human impact on the vegetation cover and related erosion and sedimentation processes in different time periods. According to this, the polycyclic climate fluctuations in the Pleistocene emerge as periods of stability and instability in the landscape system. During dry and cool periods of the Ice Ages forests drew back and erosion processes increased, causing higher erosion and deposition rates on slopes and stronger incision of river beds, accompanied by a deposition of gravels. The colluvial soils presently found in the mountain region were mainly deposited during the last instability period in the Late Pleistocene (Wisconsin) and Early Holocene. With the return of rainforests from their retreats under wetter climate conditions in the mid Holocene, slopes were stabilized under a dense vegetation cover. In the Late Holocene erosion conditions changed again with human deforestation and land use, which led to high erosion rates in the mountainous landscape. Concerning the human impact on rainforests and geomorphological process dynamics we give an overview of the pre-historical (Sambaqui, Tupi) and historical (colonial exploitation cycles) landscape transformation and degradation processes for different landscape units within the Serra dos ėrgŃos and its floodplains. The results not only give a detailed picture of historical land use patterns and landscape degradation processes, but also contribute to the understanding of rece

DevR (DosR) mimetic peptides impair transcriptional regulation and survival of Mycobacterium tuberculosis under hypoxia by inhibiting the autokinase activity of DevS sensor kinase
Background Two-component systems have emerged as compelling targets for antibacterial drug design for a number of reasons including the distinct histidine phosphorylation property of their constituent sensor kinases. The DevR-DevS/DosT two component system of Mycobacterium tuberculosis (M. tb) is essential for survival under hypoxia, a stress associated with dormancy development in vivo. In the present study a combinatorial peptide phage display library was screened for DevS histidine kinase interacting peptides with the aim of isolating inhibitors of DevR-DevS signaling. Results DevS binding peptides were identified from a phage display library after three rounds of panning using DevS as bait. The peptides showed sequence similarity with conserved residues in the N-terminal domain of DevR and suggested that they may represent interacting surfaces between DevS and DevR. Two DevR mimetic peptides were found to specifically inhibit DevR-dependent transcriptional activity and restrict the hypoxic survival of M. tb. The mechanism of peptide action is majorly attributed to an inhibition of DevS autokinase activity. Conclusions These findings demonstrate that DevR mimetic peptides impede DevS activation and that intercepting DevS activation at an early step in the signaling cascade impairs M. tb survival in a hypoxia persistence model.

Carbon Isotopic Heterogeneity of Graphite in the San Juan Mass of the Campo Del Cielo IAB Iron Meteorite
NASA Technical Reports Server (NTRS)
Maruoka, T.; Kurat, G.; Zinner, E.; Varela, M. E.; Ametrano, S. J.
The origin of IAB iron meteorites is still a matter of debate. It is generally believed that iron meteorites originated from molten cores in small planetesimals because the fractionation trend of trace elements (e.g., Ir, Ge, Ga, etc. vs. Ni) for most iron meteorites can be more or less explained by fractional crystallization from metal melts. However, this process cannot produce trace element characteristics of the IAB (and other) iron meteorites. To explain these trace element abundance patterns, several models have been proposed. Although most of these models require a high temperature, clear evidence has recently been obtained for a sub-solidus formation of IAB iron meteorites from noble gas analyses. Moreover, heterogeneous distributions of some trace elements in metal and other phases also suggest a low temperature origin of at least some IAB iron meteorites. Here we use the carbon isotopic compositions of graphite to constrain the origin of IAB iron meteorites. Our data confirm a possible low temperature origin of IAB iron meteorites.

The porosity distribution in carbonates from reefal origin is controlled both by primary and diagenetic processes (fracturing, dolomitisation and dissolution). The study and characterisation of porosity in reservoirs therefore requires a multi-scale and multidisciplinary approach.

This paper reports Primary School teachers' discourses analysis about their difficulties related to the teaching of Astronomy. It reports partial data of a master's level research carried out in the last two years, named "An exploratory study for inserting Astronomy in primary school teachers' education" (LANGHI, 2004). The study took into consideration students' and teachers' common sense conceptions about astronomical phenomena, conceptual mistakes in textbooks, and Astronomy's suggestions given by the PCN (ParŌmetros Curriculares Nacionais ¢ The Brazilian National Curriculum Standards). The paper aims to characterize teachers' difficulties, in order to provide subsides to the implementation of an initial or continuing education program. This study is justified by the fact that courses plans like these only will be adapted to the teacher's (and students') reality, if there is a primary investigation about what the teachers really need to know about Astronomy. This fact was possible here by the enunciations interpretation of a teachers' sample using semi-structured interviews, according to discourse analysis procedures. The research outcomes show difficulties related to factors like: those of personal order, methodological, on teacher's formation, educational infrastructure and other related to information sources for educators.

ORAMUS(DOS). Ozone Risk AssessMent Utilities
Whitfield, R.G.; Jusko, M.J. [Argonne National Lab., IL (United States); Biller, W.F. [William F. Biller Consultants, East Brunswick, NJ (United States)
ORAMUS is a user-friendly, menu-driven software system that calculates and displays user-selected risk estimates for health effects attributable to short-term exposure to tropospheric ozone. Inputs to the risk assessment are estimates of exposure to ozone and exposure-response relationships to produce overall risk estimates in the form of probability distributions. Three fundamental models are included: headcount risk, benchmark risk, and hospital admissions. Exposure-response relationships are based on results of controlled human exposure studies. Exposure estimates are based on the EPA`s probabilistic national ambient air quality standards (NAAQS) exposure model, pNEM/Osub3, which simulates air quality associated with attainment of alternative NAAQS. Using ORAMUS, risk results for 27 air quality scenarios, air quality in 9 urban areas, 33 acute health endpoints, and 4 chronic health endpoints can be calculated.

Resource management and fertility in MexicoÆs Sian KaÆan Biosphere Reserve: Campos, cash, and contraception in the lobster-fishing village of Punta Allen
Carr, David L.
This case study examines the link between marine resource management, and the universal contraceptive use among married couples in the lobster- fishing village of Punta Allen, located in the Sian KaÆan Biosphere Reserve, Quintana Roo, Mexico. Several reasons appear to contribute to small desired and actual family sizes. Some of these include a medical clinic staff effective in promoting family planning, cooperative and private resource ownership, changing cultural attitudes, geographical limitations to population and economic growth, and a desire to conserve the environment for aesthetic and economic motives. Lastly, families desired to preserve a sustained balance between benefiting from lobster harvests today and safeguarding this marine resource for their children in the future. PMID:19672473

M÷ssbauer and vibrational DOS studies of diluted magnetic tin oxides and nano iron oxides
NASA Astrophysics Data System (ADS)
Nomura, K.; Rykov, A. I.; Navarro, A. M. Mudarra; Torres, C. E. Rodriguez; Errico, L. A.; Barrero, C. A.; Yoda, Y.
The magnetic properties and M÷ssbauer results for SnO2 doped with 57Fe are reviewed, and the values of isomer shift and quadrupole splitting are compared with the results obtained by ab initio calculations. It is concluded that the exchange interactions between oxygen defects and magnetic atoms are responsible for long range magnetic interactions of dilute Fe ions dispersed in SnO2. Fe atom precipitated clusters may be formed in highly Fe doped SnO2 samples by annealing at relatively high temperatures for several hours. The reduction of the particle size to nano-scale dimensions induces magnetization, which can be associated with oxygen defects. We have measured the nuclear inelastic scattering (NIS) spectra of Fe oxides, and 57Fe and (Co or Mn) doped SnO2 synthesized mainly by sol-gel methods and we have derived the vibration density of states (VDOS). The local phonons are sensitive to the presence of precipitated clusters.

A social media primer for professionals: digital dos and don'ts.
Bernhardt, Jay M; Alber, Julia; Gold, Robert S
Social media sites have become powerful and important tools for health education, promotion, and communication activities as they have dramatically grown in popularity. Social media sites also offer many features that can be used for professional development and advancement. When used wisely and prudently, social media sites and platforms offer great potential for professional development by building and cultivating professional networks, as well as sharing information to increase one's recognition and improve one's reputation. They also provide a medium for increasing one's knowledge and awareness of timely news and trends by following important organizations, opinion leaders, and influential professionals. When used unwisely and imprudently, there is the potential to delay, damage, or even destroy one's professional and personal life. In this commentary, we offer recommendations for using Facebook, LinkedIn, and Twitter for professional development and caution against online behaviors that may have negative professional consequences. In summary, we believe that the strengths and benefits of social media for professional advancement and development far outweigh the risks and encourage health promotion professionals to properly engage these powerful tools.

Ensuring the relocatability of programs in the operational system DOS YeS
NASA Technical Reports Server (NTRS)
Novoseltsev, S. K.; Orlov, I. G.; Chesalin, A. S.
Specific modifications in the Disk Operational System Unified Series to insure the relocatability of programs stored permanently in the core image library is described. A self-relocating method for loading programs into the working memory with re-editing all the programs recorded in the core image library is presented. The modified linkage editor can be included in a relocation dictionary containing data about each address constant at the assembly stage at the request of the programmer. The relocation dictionary increases the dimension of the RL-phase in comparison with the dimension of this same phase when edited by the standard method, making possible the creation of multiphase program complexes. Generation and use of the modified system using Assembly language is described. An example of the use of the system is given, and limitations of the use of the relocatable programs in the modified system are outlined.

The "Bologna Open Cluster Chemical Evolution" (BOCCE) project is a photometric and spectroscopic survey of Galactic open clusters (OCs), to be used as tracers of the properties and evolution of the Galactic disk. The main OCs parameters are derived in a precise and homogeneous way, and they will be used, for example, to determine the metallicity distribution in the Galactic disk and how it has evolved with time. We present here part of our last effort, concerning the photometric data obtained for NGC 2849 and NGC 6134. FULL TEXT IN SPANISH

¾rbitas espectrosc¾picas de dos sistemas binarios tempranos usando correlaciones cruzadas bidimensionales
NASA Astrophysics Data System (ADS)
Gonzßlez, J. F.; Lapasset, E.
We apply the two-dimensional cross-correlation technique TODCOR to derive spectroscopic orbits for the two B-type double-lined spectroscopic binaries HD 66066A and HD 315031, previously mentioned as blue straggler candidates of the open clusters NGC 2516 and NGC 6530, respectively. Reliable radial velocities for both components are measured even for orbital phases for which the separation between the spectral lines are about 0.5 times the quadratic sum of the full-width at half-maximum of the lines. Both binaries have circular orbits and the orbital periods are 1.67 and 1.38 days for HD 66066A and HD 315031, respectively. We calculate minimum masses with errors of 3-5% and obtain the projected radii from the line widths. We derive absolute stellar parameters which are consistent with the age and distance of the clusters. Both binary systems are formed by main-sequence stars and it is expected that they will experience mass-transfer between their components before the end of the core H-burning stage. HD 315031 is likely a triple system as suggested by the variation of the center-of-mass velocity.

Teaching astronomy mediated by information and communication technologies: a preliminary approach

O presente trabalho ķ parte preliminar de um estudo mais amplo em nĒvel de doutorado sobre o ensino de astronomia mediado pelas tecnologias da informańŃo e comunicańŃo, utilizando dispositivos compactos, m¾veis e pessoais. Este estudo tambķm faz parte do projeto institucional do CEFETMG sobre ambientes diversificados de aprendizagem sob fomento da agĻncia estadual FAPEMIG (FundańŃo de Amparo Ó Pesquisa do Estado de Minas Gerais). Esta apresentańŃo aborda o resultado das concepń§es prķvias de estudantes em relańŃo a conhecimentos bßsicos de astronomia, ligados Ó percepńŃo e observańŃo direta do cķu. TrĻs turmas de estudantes de 1¬ sķrie e uma turma de 3¬ sķrie do ensino integrado mķdio tķcnico da EducańŃo Bßsica, Tķcnica e Tecnol¾gica (EBTT) do CEFETMG Campus II - Belo Horizonte/MG foram submetidas a uma avaliańŃo prķvia atravķs de questionßrio estruturado. Este questionßrio foi elaborado de forma a abordar a percepńŃo dos estudantes em relańŃo aos recursos grßficos (figuras e desenhos) representativos de conhecimentos bßsicos de astronomia, comuns em livros didßticos. Ap¾s a anßlise dos resultados desta avaliańŃo, organizou-se uma estratķgia de intervenńŃo didßtica em sala de aula sobre o conte·do de astronomia, utilizando-se de recursos de mediańŃo baseados nas tecnologias da informańŃo e comunicańŃo. Os temas selecionados para esta estratķgia didßtica foram relacionados aos assuntos bßsicos de astronomia em que ocorreu maior nĒvel de desconhecimento dos estudantes. Os estudantes foram submetidos a avaliańŃo posterior elaborada com os mesmos pressupostos da avaliańŃo prķvia. A anßlise dos resultados foi realizada a partir dos pressupostos da aprendizagem significativa (Ausubel; Novak e Hanesian, 1983). O ensino de astronomia por mediańŃo das tecnologias da informańŃo e comunicańŃo indica uma alternativa preliminar aos trabalhos de campo usuais orientados na prßtica escolar, tais como, visita a planetßrios e a observat¾rios. Os estudantes ficaram muito sensibilizados pela possibilidade de percepńŃo do cķu em tempo real e Ó luz do dia dentro da sala de aula no contexto escolar. Os resultados deste levantamento preliminar indicam que os nĒveis de ensino fundamental e mķdio nŃo foram capazes de internalizar conhecimentos bßsicos de astronomia, a despeito das orientań§es especĒficas contidas nos documentos oficiais da educańŃo bßsica brasileira (Brasil, 1997 e 2000). Os estudantes pesquisados apresentaram conhecimentos e concepń§es rudimentares sobre o tema astronomia bßsica, indicando a ausĻncia de abordagem do tema astronomia, tampouco de observańŃo direta do cķu em trabalhos de campo escolares na educańŃo bßsica. Finalmente, esta abordagem didßtica suscitou nos estudantes grande interesse para futuros trabalhos de observańŃo de campo. D.P. Ausubel; J.D. Novak; H. Hanesian.

Nesta etapa apresentamos os resultados da reconstruńŃo da geometria tridimensional das linhas de forńa destes arcos utilizando tķcnicas tomogrßficas, a partir de imagens de alta resoluńŃo espacial obtidas pelo instrumento EIT (Extreme ultraviolet Imaging Telescope), alķm da modelagem das induń§es magnķticas por um campo dipolar e as densidades de partĒculas aceleradas. Utilizamos para a reconstruńŃo geomķtrica, imagens tomadas em vßrios Ōngulos dos arcos devido Ó rotacŃo solar. Com estes resultados, daremos continuidade ao projeto, com os cßlculos da transferĻncia radiativa nos modos ordinßrio e extraordinßrio de propagańŃo da radiańŃo girossincrotr¶nica de explos§es solares.
Ionospheric Slab Thickness at the Equatorial Anomaly Region after the Deep Solar Minimum of Cycle 23/24
NASA Astrophysics Data System (ADS)
Duarte Silva, M. H.; Muella, M.; Silva, L. C. C.; de Abreu, A. J.; Fagundes, P. R.
This paper reports the first results of equivalent ionospheric slab thickness estimated in the Brazilian longitudinal sector. The ionospheric slab thickness is a measure of the shape of the ionospheric profile and can be obtained from the ratio of total electron content (TEC) to the F-region peak electron density (NmF2). In this study the ionospheric slab thickness was obtained during one year of extremely low solar activity (March 2009 to February 2010). The period analyzed were separated in three seasonal groups: equinoxes, June solstice (winter) and December solstice (summer) months. The ionospheric slab thickness was studied at two stations located around the southern crest of the Equatorial Ionization Anomaly (EIA). One station located in the inner edge of the anomaly region, named Palmas (10.12║ S, 48.21║ O, 7.73║ S dip lat), and another station located under the crest of the anomaly, situated at SŃo Josķ dos Campos (23.07║ S, 45.52║ O, 19.61║ S dip lat). The TEC data have been obtained from dual-frequency GPS receivers and the NmF2 data were calculated from the f0F2 parameter scaled from ionograms recorded by simultaneous measurements of digital ionosondes. The diurnal, seasonal and latitudinal variations of the ionospheric slab thickness were then analyzed. The minimum values of TEC and NmF2 were observed in both stations during the early morning, and the maximum values during afternoon hours. During the summer and equinoctial periods the slab thickness reached the higher values compared to those observed during the winter solstice months. The nearly equatorial site of Palmas showed values of daytime slab thickness larger than those observed at the low latitude station of SŃo Josķ dos Campos, except during the June solstice months. At SŃo Josķ dos Campos, a pronounced pre-dusk increase in the equivalent slab thickness was observed during the winter solstice months. From the calculated slab thickness we also inferred the atmospheric neutral temperature (Tn) over both the stations. Other relevant aspects of the ionospheric slab thickness behaviour and its comparison with International Reference Ionosphere (IRI) model results will be presented and discussed.

PETROMAP: MS-DOS software package for quantitative processing of X-ray maps of zoned minerals
NASA Astrophysics Data System (ADS)
Cossio, Roberto; Borghi, Alessandro
This paper shows an application of energy dispersive spectrometry (EDS) for digital acquisition of multi-element X-ray compositional maps of minerals in polished thin sections. A square matrix of n EDS spectra with known X, Y coordinates is collected, converted and exported to a personal computer. Each spectrum of the matrix is processed and the apparent concentration of each analyzed element is calculated by means of PETROMAP, a program written in Quick-Basic which applies a quantitative ZAF/FLS correction. The results of processing are comparable to the conventional quantitative microprobe analyses, with similar counting statistics. The output is a numerical matrix, compatible with the most popular graphic and spreadsheet programs from which it is possible to produce two-dimensional wt% oxide, mole fractions and mineral end-members pseudocolored or black/white maps. The procedure has been tested using a metamorphic garnet of the medium-grade Stilo unit (Calabrian Arc, Southern Italy).
