The paper includes the results of comparative investigation of soil organic matter (SOM) content, aggregate size distribution (ASD) and water-stability of structural aggregates (WSA) of humus horizon (0-30 cm) of non-carbonate silty clay gleyic fluvisol in the Kolubara river valley (West Serbia) under natural deciduous forest vegetation and the same gleyic fluvisol used for more than 100 years as arable soil. Long-term cultivation significantly (P 10 mm) is increased to the same degree (from 22.8-31.2 % to 48.3- 62.1%). The conversion of forest semigley to continuous cropping using conventional cultivation significantly (P 3 mm. Their content is 2-3 times lower in the plough horizon (12.6-15.6%) than in the same depth zone of forest gleyic fluvisol (31.9-42.3%). Due to anthropogenization, water-stability of micro-aggregates (< 0.25 mm) is decreased in the plough horizon. The content of these aggregates is about twice as high in this horizon (29.9-34.0%), as in the same depth zone of the forest gleyic fluvisol (16.7-17.2%).


In order to optimizing the rock mass mechanical parameters of Xi-Luodu hydropower station, the neural network is improved by coupling the partial least-squares regression. And so the coupling method has best explaining ability to the system, Solving the problem that neural network model is not stable and the calculation velocity is slow, and overcoming the bad effect of the many layers relativity among variables in system modeling. The results show that the improved neural nerwork is the superiority to the only one method. The input layers of neural network discrease from 4 to 2 , so to simplize network construction and strengthen network stability. The concise is 0.0002 when calculating times are less than 500, and 96% of forecast errors are less than 20%, and all predict errors are no more than 1%. So the improved CMAC neural network can provide a good idea to optimize rock mass mechanical parameters


Jackson, W.-A., F. Piper and P. Wild, Non-embedding of non prime-power unitals with point-regular group, Discrete Mathematics 98 (1991) 23-28. Mathon (1987) and B. Bagchi and S. Bagchi have constructed a class of Steiner 2-designs, including some unitals, admitting a point-regular automorphism group. We show that any unital constructed by this method cannot be embedded in a projective plane n in such a way that the unital arises from a polarity and the point-regular group of the unital is induced by an automorphism group of R.


A Solar Power Station/Satellite (SPS) is expected to become one of the sustainable energy sources for the next generation. One of the most important technologies for realization of the SPS is Wireless Power Transmission (WPT) from space to the Earth. The objective of the present study is to develop high-efficiency and low-noise WPT. A SPS requires high overall WPT efficiency, and a high-efficiency WPT system also contributes to cost reduction and lightness in weight of the SPS from the viewpoint of thermal management. Low-noise WPT is also important since a SPS is necessary to ensure electromagnetic compatibility (EMC) with other radio applications. In our research group, a magnetron is used for a microwave power source of a SPS transmitting system, because its DC-RF conversion efficiency is higher, it costs less, and it has smaller weight/power ratio than solid state devices. However, a magnetron has a wide oscillation bandwidth and it generates spurious noises in various frequency bands. We have achieved magnetron noise reduction, developed a Phase-Controlled Magnetron (PCM), phased array transmitting systems (SPORTS systems) and a compact 5.8GHz PCM (COMET). A development of 5.8GHz CW magnetrons also contributes to reduction in size and weight of the SPS transmitting system, compared to the conventional 2.45GHz magnetron. In this paper, our recent research activities on the WPT transmitting systems are introduced.


Introduction Built-in car hands-free telephones may consist of different components consequently leading to a heterogeneous system design. Each component like the microphone (or microphone array respectively), the hands-free unit itself and sometimes the mobile integrated additionally introduce various kinds of signal processing. This may even lead to cascaded algorithms providing the same kind of, or at least comparable signal processing in order to improve speech quality. A typical example is the noise reduction which can be found in the microphone array (beam forming, algorithmic noise reduction), additionally in the hands-free unit and in the integrated mobile. In order to guarantee a good speech quality for the complete system it is absolutely necessary to choose the parameter settings of these algorithms according to the characteristics of the cascaded systems. Typically these cascaded systems have been optimized independently of each other and the combination of the systems do not necessarily lead to a sufficient speech quality of the whole system. Guidelines are discussed how these complete systems can be optimized.


Firstly,based on SI model,this paper builds the diffusion model of quality and safety information by comparing the similarity between system components as well as propagation of SI model and the diffusion model of quality and safety information. Secondly,in order to analyze and get the diffusion law of quality and safety information,this paper improves the defect that λ and μ are fixed value in the SI model as well as simulates diffusion process of the different modes and different public attention by the simulation calculation of Matlab. Finally,for the existence of security risks of Yunnan rice noodle,decision- making departments can take corresponding measures before the coming of peak period by forecasting the entire information diffusion process when food safety incidents will happen and the arrival of the peak period of the time t.


In the early days of the 12th century, the fall of the Muslim Empire and capture of Cordoba was taking place in the kingdoms of Spain. The process of Reconquista that began in the south-east of Andalucia, through the province of Jaen, and continued towards the most important city of the ter- ritories of Al Andalus, Cordoba. A new period in art and history began, influenced by trends of the Kingdom of Castilla, already under the control of Christian kings. In the course of this new stage, a new architectural typology emerged in the city. It had religious purpose and are known as the pal- ace-convents. One of the most important edifices is the Santa Marta convent along with its church, a landmark in late Gothic architecture. It owes such characteristics to families of stonemasons and sculptors who arrived from Burgos, making the city into this magnificent site. The main facade of the church was sculpted and designed in 1511 by Hernan Ruiz I, master of the cathedral (former mosque of the caliphate). This front is the subject of research and restoration work, which revalued this architectonical assortment of the Cordoba of the 16th century.


China adopts the trust mode of management which is the combination of the trust and client-agent relationships.There are many risks in the two levels of the Occupational Pension's management,so It is necessary to take some effective measures to reduce the risks in the two levels relationships which are inevitable choice of enhancing efficiency of the management.


Some new 3-(substitutedphenyl)-2-methyl-2-p-tolylthiazolidin-4-ones (3a-t) were prepared by refluxing the 1-ptolylethanone (1) with different aromatic amines (2a-t) in presence of thioglycolic acid in benzene (one pot synthesis). The title compounds have been characterized on the basis of elemental analysis, IR, 1 H-NMR and 13 C-NMR spectral data. All the synthesized compounds have been screened against four different bacterial strains S. aureus, S. paratyphi-A, E. coli and B. subtilis and fungal strain F. molaniforme and A. niger. Some of them showed good antibacterial and antifungal activity compared to reference drugs used in the study.


The investigation of PM_(2.5) aerosols using a portable mini-volume sampler was conducted between May 22 and September 22,2006,in high-tech zone,Xi'an.Meantime NH_3 gases were also sampled using passive Ogawa sampler.Water soluble ions(WSI) and NH_3 concentrations were analyzed using an ion chromatogram(IC) analyzer.Integrating these data with SO_2 and NO_2 mass concentrations,the characteristics and sources of WSI of PM_(2.5) in spring and summer in Xi'an were studied.The results indicated that WSI in spring and summer was mainly composed of SO~(2-)_4,NO~-_3 and NH~+_4,accounting for 21.68%,7.52% and 5.62% in mass,respectively,and the PM_(2.5) in spring and summer in Xi'an were generally acidic.SO_2 mass concentrations were poorly correlated with SO~(2-)_4,NO~-_3 and NO_2,indicating that sulfate,nitrite,and ammonium in Xi'an are of different origins.

Monteggia fracture dislocations can be classic or equivalents. Equivalents, also known as Monteggia like lesions, are very rare especially type III and IV, which have been added to the literature after Luis Bado presented the original classification system of Monteggia fracture dislocations. Type III equivalent is classically defined as a proximal ulna fracture associated with a fracture of the lateral condyle of the humerus. In the literature only seven such cases have been reported so far. Here we present two such cases where one eight-year-old boy had a complex type of injury with a shear type fracture of the lateral humeral condyle and other a seven-year-old boy who had a plastic deformity of the ulna with an avulsion type fracture of the lateral humeral condyle. We also try to describe a novel mechanism of injury, known as, "Barzulla circle", for the classical as well as equivalent type III Monteggia fracture dislocations.


In recent years, increasing emphasis has been placed on the identification of patients with supportive and palliative care needs. Prognostic models have been introduced in the UK, Holland and Catalonia to aid clinical decision-making in patients with advanced conditions at risk of dying.1–3 This journal has recently published a review of such tools and a survey of their usage throughout Europe.4 However, as the collective drive to identify patients intensifies, it is reasonable for health professionals to question the value of such an investment of time and effort. Due to the variable trajectory of chronic disease, many patients identified as being in the last year of life survive beyond this period, often by …


The study of air quality in communities located in the direct vicinity of open coal mining is a big environmental problem. It is viewed as a social order and is an actual scientific and practical task of geoecology. The article describes the impact of pollutants on human body in the climatic conditions of the Transbaikal region. In particular, the influence of the coal mine «Vostochny» on the neighboring locality «Drovyanaya» is described. The development features of the coal mine «Vostochny» are presented by the use of less transport development system; large-scale length of field of operations work's and accordingly great parameters of dumps, blasting, equipment wear, and most importantly, the proximity of mining operations directly to the neighboring locality «Drovyanaya» and other settlements, the presence of a large number of air pollution sources. At present 650 m^3 of mining waste products, especially of non-cultivated ones, account for per head of population. Due to this indicator Transbaikal region holds the first place in the world. It is noted that the emission of pollutants from coal mines contributes to several pathological diseases. The urgency of air pollution the problem and its impact on the people's health of neighboring localities is outlined. The analysis of incidence rate and newly diagnosed diseases in the neighboring locality «Drovyanaya» district of Transbaikal region is carried out. On the bases of population's incidence it was revealed that people of neighboring locality «Drovyanaya», have a threatening situation with a health condition that requires immediate action to improve the environmental situation by introducing technical innovations.


Patzkea paniculata usually dominates grassland communities in the subalpine and alpine belts. The analysis of a unique vegetation community found at low altitudes growing on serpentinitic substrates in the North-Western Alps (Italy) dominated by P. paniculata, is hereby presented. These communities are substantially different from already described alpine communities, framed in the alliance Festucion variae (class Caricetea curvulae, order Festucetalia spadiceae) and typical of higher elevations. Syntaxonomic and ecological investigations were performed to provide a correct phytosociological framework for these grasslands. The new association Potentillo albae-Patzkeetum paniculatae ass. nova is here described, with two different variants, one co-dominated by Bromopsis erecta and the second with co-dominance of Molinia arundinacea. It is a secondary grassland of arid environments attributable to the alliance Bromion erecti (class Festuco valesiacae-Brometea erecti), and characterized by the presence of numerous species, both rare and typical of serpentinitic substrates.


The effects of high pressure on the thermochromic and related complexes [CuL 2 ]X 2 [L=N,N-diethylethylenediamine X=BF 4 − , ClO 4 − , Cl − ; L=N,N-dimethylethylenediamine, X=BF 4 − ; L=ethylenediamine, X=BF 4 − ] are described. Electronic and infrared spectroscopies indicate an increase in the interaction between anion and molecular CuN 4 plane of all complexes with increasing pressure


Abstract At a sufficiently high Reynolds number small separation bubbles, as for example at the leading-edge of an aerofoil, are characterised by laminar flow separation and turbulent reattachment. The transition to turbulence in the separated-flow region through the introduction of a disturbance at the boundary, localised in time and space, is examined. It is found that transition to turbulence is promoted by rapidly growing convective instabilities, and not an absolute instability at the point of application of the disturbance.


The Defense Advanced Research Projects Agency (DARPA) OFFensive Swarm-Enabled Tactics (OFFSET) program seeks to develop swarms of up to 250 aerial- and ground-based platforms to aid small-unit infantry forces to accomplish missions in complex urban environments. Over the course of four years, the OFFSET performers regularly tested and improved the autonomy, hardware, communications infrastructure, and logistics necessary to enable such a vision. In this paper, we present the Immersive Interaction Interface (I3), a virtual reality interface designed by Smart Information Flow Technologies (SIFT), as part of the BBN/Raytheon-led Command and Control of Aggregate Swarm Tactics (CCAST) team. I3 served as the main control interface for the team throughout the program, and this paper discusses the primary innovative features of I3 as compared to prior swarm control interfaces, how I3 was used in the field during exercises, and lessons learned over the course of the program. The paper also presents numerical results from the final three field exercises of the OFFSET program, demonstrating how a single operator used I3 effectively to control large numbers of unmanned vehicles.


This paper analyses the current state of design and usage of cross media storytelling. In line with the session 'matrix', works will be assessed according to patterns of low, moderate and high acceptance and diffusion. Preliminary observations are offered to assist in the formation of characteristics of, and design guidelines for, cross media works. 1 Classifying cross media storytelling As recognised by Hannele et al. cross media has multiple meanings: the term can refer to '[c]reate once, publish anywhere', 'ability to leverage content over a variety of media' and 'creation and implementation of single graphics for a variety of media' (Hannele et al., 2004, 19). Unlike these usages this paper addresses the phenomenon of cross media storytelling, which Monique de Haas defines as 'communication where the storyline will direct the receiver from one medium to the next' (Hannele et al., 2004, 19). De Haas' definition rightly places the activity of the user of a cross media work and the role of the storyline in directing this activity as primary elements. 1.1 User activity Espen Aarseth differentiated between the interpretative and constructive aspects of reading and physical activity by outlining a category of literature that requires the later: 'ergodic literature' (Aarseth, 1997). For Aarseth, the activity (such as following a hyperlink, turning a knob, moving a joystick) is needed to access a work and for meaning-formation (ibid., 1). The user of a cross media work, an ergodist perhaps, does indeed need activity to access the work. Cross media games that require the player to search for the content as explained by the designers of the 'immersive game' The Beast (Microsoft and Dreamworks, 2001): 'We [4orty 2wo Entertainment] tell our stories in the form of "search operas" -narratives that spill off the page, the screen, the web, the phone--and into peoples' lives. We don't send an advertising message into the maelstrom of other competing messages: we reverse-engineer the process, so that the consumer comes looking for our campaign and our


AbstractThe corrosion of mild steel by chlorinated solvents has been investigated. The evidence of acid formation as a result of decomposition of CCl4 and of the corrosive action of the degraded solvent on mild steel has been reported. In the presence of water in CCl4 a number of metals produced acid, both when exposed in the liquid or in the vapour, more in the latter case. In general, the catalytic activity of different metals in decomposing CCl4 was in the following decreasing order: mild steel, aluminium, copper, zinc. Nickel, stainless steel and brass did not decompose the solvent. Higher temperatures (> 10°C), longer test periods, a higher water content, the presence of inorganic contaminants and exposure to UV radiation caused more decomposition of CCl4 and greater attack on mild steel. Boiling solvent (containing H2O) or the vapour therefrom prodūced greater corrosion. Hot condensate either flowing past the metal specimens or wetting and drying them alternately produced maximum corrosion.

Ta coating was prepared by using plasma spraying technique.The effects of plasma spraying power and distance as well as powder feed rate on temperature and ve-locity of Ta particles during plasma spraying were investigated.The microstructure of the coating was analyzed by means of scan-ning electron microscopy.Moreover,the friction and wear behav-ior of the coating under dry sliding conditions was evaluated by using a ball-on-disc friction and wear tester.Results show that temperature and velocity of the in-flight Ta particles are highly dependent on spraying power and distance as well as powder feed rate.The optimized spraying power,spraying distance and pow-der feed rate were determined to be 36 kW,150 mm and 45 g/min respectively.Resultant Ta coating had dense structure and good wear resistance with a density of 15.2 g/cm3,hardness of 759 HV and tensile strength of 40 MPa and above.The Ta coat-ings obtained under different plasma spraying parameters had sim-ilar friction coefficient,and their sliding wear failure was domina-ted by fatigue-spalling.


Context: Ultrasound is an excellent modality for the evaluation of the soft tissue structures as well as articular pathologies of the elbow joint. Higher resolution transducers along with the superficial location of the elbow structures make them amenable for easy visualisation However, the long learning curve and the operator dependency can limit its use. Aims: The aim of this article is to describe and demonstrate novel techniques to image distal biceps tendon, lateral ulnar collateral ligament and radial nerve at elbow joint with ease. Design: Technical advancement. Methods: The elbow joint ultrasound examination was performed on ten asymptomatic volunteers, 20–40 years old, using a linear probe of 3–13 MHz frequency. The scanning was started from the anterior elbow, the distal biceps tendon was visualised first with anterior to the medial approach followed by the lateral ulnar collateral ligament with one finger technique and radial nerve with first bone technique respectively. Conclusion: We consider our techniques as an easy approach to identify the distal biceps tendon, lateral ulnar collateral ligament and radial nerve.


Oxidation of organic matter with H2O2 produced substantial amounts of NH3 which was then fixed by vermiculite, causing partial or complete collapse and converting the mineral to a mica-like product. The collapse of the mineral was indicated by shifts in the 001 spacing from 1.476 to 1.030 nm and the appearance of a well-defined band at 1430 cm−1 in the IR spectrum, indicative of the presence of NH4+ in the interlayer positions of the clay. Our data suggest that: (a) the transformation of vermiculite to mica during H2O2 oxidation may result in underestimation of the vermiculite content of soils by XRD, and (b) the wide occurrence of mixed-layer minerals in soils may in part have resulted from the fixation of NH3 liberated from the microbial mineralization of organically bound N. Key words: Ammonia, X-ray diffraction, IR spectrophotometry, mixed-layer minerals, H2O2 pretreatment


This study aims to calibrate the instrument of argumentation skills on the subject of Fluid Statics using item response theory (IRT). The blueprint instrument developed based on the aspects and sub-aspects of argumentation skills, totaling 20 items. The scoring uses the Partial Credit Model (PCM) principle in 4 categories. Subjects involved in the study were 206 undergraduate students at two different universities. The validation of the instrument using expert judgment techniques, which consisted of linguists, physicists, and educational measurement experts. Instrument calibration for argumentation skills is carried out by (1) analysis of item fit with PCM by testing goodness of fit items, (2) testing prerequisite analysis, (3) reliability, (4) difficulty level, and (5) Standard Error of Measurement (SEM). The test developed is valid with Aiken V index values in the range 0.93 to 1. The analysis of IRT assumptions uses two parameters, the adequacy test of the sample and the factor analysis. The Chi-Square value in the Bartlett test is 2202.67 with df 190, and a p-value value (Sig.) <0.05 indicates that the sample size used has met the unidimensional requirements. The instrument developed has met the criteria for scoring the Polytomus items, based on a) the MNSQ INFIT value is in the range of 0.70 to 1.30, and b) the difficulty index test is in the range -2.00 <b <2.00. The results of the reliability estimate on the test equipment obtained a reliability value of 0.86, which means that the reliability of the test is in the high category. The graph of the information function and SEM converge on the ability scales of -2.8 and +1.5, meaning that the skills test kit argues it is suitable for testees in the low to moderate ability range.

The power and procurement cost of bandwidth in system-wide networks has forced a steady drop in the byte/flop ratio. This trend of computation becoming faster relative to the network is expected to hold. In this paper, we explore how cost-oriented task placement enables reducing the cost of system-wide networks by enabling high performance even on tapered topologies where more bandwidth is provisioned at lower levels. We describe APHiD, an efficient hierarchical placement algorithm that uses new techniques to improve the quality of heuristic solutions and reduces the demand on high-level, expensive bandwidth in hierarchical topologies. We apply APHiD to a tapered fat-tree, demonstrating that APHiD maintains application scalability even for severely tapered network configurations. Using simulation, we show that for tapered networks APHiD improves performance by more than 50% over random placement and even 15% in some cases over costlier, state-of-the-art placement algorithms.


-Bubo osvaldoi, new species, is described from three bones from a Pleistocene cave deposit in the Sierra de Galeras, Pinar del Río, western Cuba, with two additional paratypes referred from Baire in the province of Santiago de Cuba, in the eastern part of the island. The species is the only representative of the genus Bubo and the tribe Bubonini in the Antilles and in size was larger than any living owl. Resumen.•Se describe una especie nueva de buho. Bubo osvaldoi, de tres huesos del Pleistoceno hallados en una cueva de la Sierra de Galeras, en Pinar del Río, Cuba occidental, y de otros dos huesos paratipos procedentes de Baire, provincia de Santiago de Cuba, en el oriente de la isla. La especie es el único miembro del género Bubo y de la tribu Bubonini conocido hasta ahora en las Antillas y era mayor que cualquiera de las formas conocidas de buhos vivientes. The Quaternary avifauna of Cuba is remarkable for the number and size of the extinct owls that have been discovered there (summarized by Arredondo 1976, 1982). These include the truly enormous strigids of the endemic genus Ornimegalonyx, of which four species have been named (Arredondo 1982), and two species of bam owls {Tyto) that far exceed in size any living species of Tytonidae. Pulsatrix arredondoi (Brodkorb 1969) is slightly smaller than its Neotropical relative P. perspicillata, but belongs to a genus otherwise unknown in the Antilles. It was previously known only from the type locality, Cueva Paredones in Habana Province, but Arredondo has recently identified a tarsometatarsus of P. arredondoi from Cueva Calero in Matanzas Province. Here we present evidence of yet another very large extinct Cuban owl, amidst what could already have been regarded as a plethora. Our collaboration on this began when Arredondo forwarded for evaluation three fossil specimens from Pinar del Rio, at the western end of Cuba, along with a manuscript describing them as a new species of Bubo. This called to mind two enigmatic bones that Olson had studied some years previously that came from the former province of Oriente, at the opposite end of the island. These had originally been sent in January 1947 by Abelardo Moreno, then of the Museo Poey, to Alexander Wetmore, at the Smithsonian Institution. Wetmore had had a drawing made of these bones and left a folder of correspondence concerning them, but they remained unpublished. We have concluded that these probably belong to the same species as represented by the bones from Pinar del Rio, which cannot be referred to any known species of owl, living


A key is provided for the identification of the five species of the subgenus Eriolophyra Rivalier 1948 of the genus Lophyra Motschulsky 1859 (Coleoptera Cicindelidae): L. (E.) alba (Horn 1894); L. (E.) albens (Horn 1895); L. (E.) arnoldi (Horn 1904); L. (E.) barbifrons (Boheman 1848); and L. (E.) somalia (Fairmaire 1882). The taxonomy of this subgenus is reviewed and Lophyra (Eriolophyra) barbifrons marqueza (Peringuey 1896) is placed as a synonym of L. (E.) barbifrons . Information about the ecology of species of Lophyra (Eriolophyra) is summarized: Lophyra (Eriolophyra) alba , L. (E.) albens , and L. (E.) arnoldi are associated with sandy riverine areas in southern, central, and west-central Africa, respectively, while L. (E.) barbifrons and L. (E.) somalia are associated with coastal sand beaches in southern and eastern Africa, respectively. Descriptions of adult foraging, thermoregulatory, reproductive, and defensive behaviors are provided for L. (E.) alba , based on recent observations at sites along the Letaba River in Kruger National Park, South Africa. A hypothesis of phylogenetic relationships is proposed for the five species of the subgenus Eriolophyra on the basis of adult morphological characteristics. Morphological characters suggest that this group forms a monophyletic clade within the broader complex of species allied to Lophyra .

The article is devoted to the practically unexplored issue of the rationalization movement on the territory of the Chechen-Ingush ASSR during the Great Patriotic War, which explains its relevance. The aim is to determine the degree of impact of the activities of innovators on improving the efficiency of the oil production and refining industry of Chechen-Ingushetia during the study period. The article is written mainly on the materials of the Republican newspaper "Grozny worker" (organ of the Chechen-Ingush regional Committee of the CPSU(b), allowing with a sufficient degree of completeness to recreate the scale of activity of inventors and innovators and to describe the impact on the oil industry of national economy. Separate data are taken from published even in Soviet times of works M. A. Abisalova and S. O. Zoeva. In the work on the article, comparative-historical and problem-chronological methods were used, which made it possible to identify the general and special in the described historical events and to consider the activities of the CHIASSR rationalizers of the period of the Great Patriotic War in chronological order. Based on the materials used, it can be concluded that although not all of the proposed rationalization proposals were implemented, in general, they allowed the state to save significant financial and material resources. Was thereby made a significant contribution to the increase of efficiency of activity of the Republican oil industry complex. The Republican corps of inventors and innovators consisted mainly of engineering and technical workers and highly qualified workers, and the bonuses given to innovators for implemented proposals amounted to a significant increase in the income of about a thousand employees and their families.


This review paper summarizes the findings of a literature review examining the evidence for and against the existence of the "healthy immigrant effect" for mental health in Canada. The methodological strengths and weaknesses of the present body of literature were examined, followed by recommendations for future research. The literature review yielded inconclusive evidence. The "healthy immigrant effect" for mental health did not hold true across all immigrant populations. Rather, it varied by factors such as country of origin, visible minority status, and wave of immigration. Future studies need to consider these important factors and include analyses of longitudinal data to further elucidate the "healthy immigrant effect" for mental health in Canada.


traditional, paper-based format. The significantly greater reliability afforded by computerization highlights its potential for cost effective utilization in clinical trials and related research protocols, on which improved reliability directly translates into reduced sample-size requirements and associated cost savings. Furthermore, the computerized ADAS is hosted on a unique, dual-monitor testing system (CMINDS) that features multimedia presentation of test stimuli and instructions, integrated project management and reporting capabilities, and a wide range of additional neurocognitive and behavioral assessment instruments commonly applied in the characterization of MCI.


In this paper, we construct examples where the multiplicities of rank two Galois representations in the localized first cohomology groups of Shimura curves over totally real fields are greater than one. These examples generalize the result of Ribet for Jacobians of Shimura curves over Q and are closely related to the BDJ conjecture.

The use of fibers to feed spectrographs is a very efficient way to increase the precision of radial velocity measurements. It has already proved to be successful with the very first detection by the ELODIE fiberfed spectrograph of the planet orbiting the star 51 Peg. The basic key properties of fibers in the very high radial velocity precision measurements context are described in this review. The ELODIE spectrograph is used to illustrate the thorium simultaneous calibration technique. The use and the effects of a double-scrambler to increase the stability of the slit illumination are also discussed.


Massive storage systems composed of tens of thou-sands of disks are increasingly common in high-performance computing data centers. With such an enormous number of components integrated within the storage system the probability for correlated failures across a large number of components becomes a critical concern in preventing data loss. In this paper we reconsider the efficiency of traditional declustered parity data protection schemes in the presence of correlated failures. To better protect against correlated failures we introduce Single-Overlap Declustered Parity (SODP), a novel declustered parity design that tolerates more disk failures than traditional declus-tered parity. We then introduce CoFaCTOR, a tool for exploring operational reliability in the presence of many types of correlated failures. By seeding CoFaCTOR with real failure traces from LANL's data center we are able to create a failure model that accurately describes the existing file system's failure model and can use that model to generate failure data for hypothetical system designs. Our evaluation using CoFaCTOR traces shows that when compared to the state of the art our SODP-based placement algorithms can achieve a 30x improvement in the probability of data loss during failure bursts and achieves similar data protection using only half as much parity overhead.

ABSTRACT Drawing upon ethical climate theory and conservation of resource theory, this study provides a theoretical model to explain the effect of a perceived caring climate in the workplace on the employees' turnover intention through the serial multiple mediation of workplace incivility (caused by coworkers) and employees' emotional exhaustion. A total of 291 frontline employees from the service industry in Norway participated in this study, and structural equation modeling (SEM) was used to analyze the data. The findings indicated that a caring climate has a significant negative effect on turnover intention. The mediating effect of coworker incivility was not supported in the multiple mediation model; however, it was supported if it was considered as the only mediator in the relationship between caring climate and turnover intention. Moreover, emotional exhaustion mediated the relationship between caring climate and turnover intention. The serial mediation effect of coworker incivility and emotional exhaustion was also supported in the relationship between caring climate and turnover intention. The results of this study enable managers to create a caring climate in the workplace and minimize the detrimental effects of incivility and turnover intention in the service industry.


The war against U-boats in the Atlantic was won in part by a high-frequency direction finder -- called Huff Duff or HF/DF for short -- that could pinpoint the location of radio transmitters. The story of HF/DF's development and operation in combat by the U.S. Navy is told here for the first time in revealing detail.


The purpose of the project is to create a learning software for autistic and dyslexic children. The goal of the project is to make the children choose a language and then using a custom speech -to- text classifier make the children repeat and pictographically learn various words. Teaching autistic and dyslexic is a very difficult task as they have a difficulty in learning and differentiating between different languages. We aim to create the model and categorize words from different languages, mainly English and Hindi. Currently, with models present, the problem in the models is that they are unable to detect the accent in which native Indian speakers speak. Thus, creating a model which can be used naturally over the whole country is a difficult task. The created model would be able to differentiate and understand a handful of words, and with a much powerful engine and dataset, it would be able to act as a modern-day text to speech and a teaching tool for the autistic and dyslexic children.


Southern Flying Squirrels (Glaucomys volans) were trapped from June-October 2013 at three mature forest sites dominated by hardwood trees in southwestern Virginia to determine variability in capture rates among sites and to relate them to different habitat variables. Nineteen squirrels were captured in similar numbers at two sites, with no captures at the third site. The density of cavity trees was the most important variable related to capture success, along with the relative proportion of conifer tree basal area, the amount of downed coarse woody debris, and the density of hard mast-producing tree species. Capture success was negatively related to percent slope. This study indicates that Southern Flying Squirrels select habitat based on several variables and may not be a generalist species of mature forests.


A lot of journalists and preparative journalists appear in Zhang Henshui's artistic world. These characters' narrative function exceeded their image function. They appear everywhere and bring a great freedom to narrative, and many stories are told naturally by them. The author's wisdom in exertion of the degree of narrative freedom has something to do with his experience as a journalist for a long time.


THE HISTORICAL SOCIETY OF PENNSYLVANIA was recently given a small leather-bound volume bearing the inscription "To be given to Richard Thomas as verbally promised by me James Taylor." Examination of the book revealed it to be of more than usual interest, containing as it does "Notices & Anecdotes" respecting a variety of subjects as recorded by an astute and curious observer who had had the advantage of personal acquaintance with most of the subjects of his notices. These include brief memoirs of both Scots and American personalities, many of whom were ecclesiastics, but of a variety of denominations. Among members of the clergy mentioned are the Rev. Benjamin Allen, the Rev. Dr. Stephen B. Balch, the Rev. Dr. Hugh Blair, and the Rev. Colin Campbell. Anecdotes concerning secular persons relate to Samuel Chase, Benjamin Chew, Thomas McKean, and the redoubtable Dr. Samuel Johnson. While often of penetrating insight, frequently of a humorous turn, and occasionally mordant, it is obvious that not all the observations could have been original with Taylor, and it is perhaps not impertinent to suppose that some of the notices were collected as sermon material, as well as for their overt entertainment value. From some abstracts at the First Unitarian Church, Philadelphia, made from a now unlocated autobiographical sketch by James Taylor, and from Dr. Elizabeth M. Geffen's Philadelphia Unitarianism (Philadelphia, 1961), the salient facts of Taylor's life may be obtained. Born in 1767 in Perth, Scotland, Taylor was put to learning the weaving trade in 1782. By the time he removed to his uncle's house in London, in 1785, he was deeply interested in religion. The memorial abstracts mentioned above state "In September, 1791, he went to Bath. . . . While there, he attended Mr. Jardine's chapel called the Presbyterian House, although Mr. Jardine was a decided

Vegetated filter strips (VFS) are a best management practice, designed to reduce sediment and nutrient runoff to surface waters in agricultural landscapes. In cold climates, phosphorus (P) can be released from VFS vegetation when it undergoes freeze–thaw cycles, making their utility in these regions an area needing further study. Research in Manitoba, Canada, investigated temporal changes in soil P concentrations and potential P loss from VFS from 2015 to 2017. Soil, harvestable vegetation, and residue samples were collected within VFS and control strips, and soils were analysed for Olsen P and Total P (TP). Harvestable vegetation and residue samples were analysed for TP. Results showed increases in Olsen P each spring and reductions each fall in soils at all sites. There was substantial loss of TP from the harvestable vegetation samples at all sites from November 2016 to May 2017, but residues in the VFS and control sites had a lower loss of TP over the same period. Vegetation was shown to release P over the winter into surface soils, and harvestable vegetation released significantly more P than residue, potentially leading to P loss from soils through surface runoff or leaching. Thus, harvesting vegetation may be a suitable VFS management strategy in cold climates.


The Smackover Formation in central Mississippi is sour gas productive from siliciclastics interbedded with tight carbonates. The sandstones have low reservoir quality (porosity and permeability of 7.0% and 0.35 md, respectively), but wells are capable of producing at high rates and with large volumes because of the extremely large geopressures and locally thick continuous sandstone packages. Production is from a hostile subsurface environment which includes high temperatures (>365{degree}F), high pressures (>0.88 psi/ft), great depths (>20,000 ft), and variable and corrosive sour gas mixtures (CH{sub 4} = 55%, H{sub 2}S = 36%, CO{sub 2} = 9%). Five fields are productive in this trend; Thomasville, the largest field, is used to illustrate the depositional and diagenetic controls on productivity. Deposition occurred as an upward-shoaling sequence of outer ramp to nearshore and sabkha environments. The lower sandstones are bioturbated, low-quality reservoirs interbedded with carbonate mudstones and packstones; the middle interval consists of the thickest and most continuous sandstones that are interpreted to be amalgamated inner-ramp shoal and ridge deposits; the upper interval consists of the common but tight Smackover ooid grainstone shoals that are interbedded with continuous but thin shoal and shoreface sandstone. The middle interval has the best reservoir quality and contains more » 75% of the hydrocarbons. Seismic may be used to map the sandstone packages but not the individual sandstones. In addition to the larger net/gross and more continuous sandstones in the middle zone, two postdepositional controls also govern the reservoir quality. These include small-scale faulting but more importantly diagenetic events which strongly overprint but do not obscure the original depositional control. At least 15 different diagenetic events have occurred in the sour gas fields that have generally decreased reservoir quality. « less


Palmarosa is one of the commercially important essential oil yielding crops of India. Improving the herbage and essential oil yield through appropriate breeding methods is the major objective of this crop. Being a cross pollinated crop, its improvement can be made through mass selection. Fifteen best palmarosa clones are identified from two years of individual plant screening of seven germplasm material for different growth, yield and quality parameters formed the base material for this study. The slips of fifteen selected clones were planted in the polycross nursery at ICAR-DMAPR, Anand, Gujarat. The composite hybrid seeds of palmarosa were collected separately from each clone from the polycross nursery. In the present study, the performance of composite hybrids along with check was evaluated to identify best performing polycross hybrids for herbage and essential oil yield. Two hybrids DCMH 8 and DCMH 10 had more than 22 per cent higher dry herbage yield than the commercial variety Trishna. The polycross hybrid progeny proved to be significantly superior with respect to essential oil content and percentage of essential oil recovery. Among the hybrids DCMH 8 had the highest oil yield (16.08 g/plant), which was 37.79 per cent higher than check variety. Based on the performance of the polycross composite hybrids, top performing five hybrids viz., DCMH 1, DCMH 6, DCMH 8, DCMH 10, and DCMH 14 were selected and advanced to multi-location trials across different centers to identify the best one for release as a commercial composite variety.

Background The composition of the infant microbiome can have a variety of short- and long-term implications for health. It is unclear if maternal probiotic supplementation in pregnancy can impact infant gut microbiome. Objective The aim of our study was to investigate if maternal supplementation of a formulation of Bifidobacterium breve 702258 from early pregnancy until three months postpartum could transfer to the infant gut. Study design This was a double-blinded placebo controlled randomised-controlled trial of B. breve 702258 (minimum 1x109 colony forming units) or placebo taken orally from 16-weeks gestation until three-months postpartum in healthy pregnant women. The primary outcome was presence of the supplemented strain in infant stool up to 3 months of life, detected by at a least two of three methods, i.e., strain specific PCR, shotgun metagenomic sequencing, or genome sequencing of cultured B. breve. 120 individual infant stool samples were required for 80% power to detect a difference in strain transfer between groups. Rates of detection were compared using Fishers exact test. Results 160 pregnant women with average age 33.6 (3.9) years, mean BMI of 24.3 (22.5, 26.5) kg/m2 and 43% with nulliparity (n=58) were recruited from September 2016 to July 2019. Neonatal stool samples were obtained from 135 infants (65 in intervention and 70 in control). The presence of the supplemented strain was detected through at least two methods (PCR and culture) in two infants in the intervention group (n=2/65, 3.1%) and none in the control group (n=0, 0%), p = 0.230. Conclusion Direct strain transfer from mothers to infants of B. breve 772058 occurred, albeit infrequently. This study highlights potential for maternal supplementation to introduce microbial strains into the infant microbiome.


The most intensive X-ray diffraction peaks for three types of carbon allotropes are analyzed: i) temperature-annealednanodiamond powder (carbon "onions"), ii) multi-walled carbon nanotubes, iii) layers of epitaxial graphene. A re-construction of the X-ray diffraction pattern using an intershell distribution, obtained by high resolution transmis-sion electron microscopy, was compared to the XRD data. For a qualitative analysis of the diffraction profiles,the method of convolution of Lorentzians (size broadening profile), together with a statistical consideration ofinterlayer spacings (lattice strain broadening profile) were used. For the case of iii) the statistical distributionreduces to a Gaussian and the method itself transforms to a best fit procedure of the classical Voigt function to theexperimental data. For cases i) and ii) and the high-resolution electron microscopy-reconstructed data, the methodfits the experiment better using either negatively or positively -skewed statistical distributions, correspondingly.A model of particles with a spiral internal structure and with radius-dependent spacings between the successiveturns may explain experimental data for these cases. The data for epitaxial graphene allows different interpretations,including fluctuations of lattice spacings caused by distortions of the valence bands and angles in the grapheneplanes or by the formation of scrolls.


Stability and reusability are the major issues for a solid acid to be considered as an alternative for conventional homogeneous acids currently applied in industries. In this study, a novel solid superacid was prepared by implanting an alkaline earth metal, Sr, in a ferric oxide matrix. Sulfate groups were then grafted onto the prepared Sr–Fe composite oxide in order to facilitate the charge separation effect between the surface Sr cation and the adjacent oxygen anion, while Cl− ions were covalently coordinated onto the catalyst in order to suppress the inactivation caused by saponification of surface Sr cations on the catalyst when the catalyst was applied to carry out the model reaction, the esterification of oleic acid with methanol. After surface modification, the acidic properties of the prepared catalyst were characterized by TGA, pyridine FT-IR and n-butylamine back-titration. The FT-IR spectrum of the catalyst with adsorbed pyridine revealed that the surface active sites were dominated by Bronsted acid sites. The catalytic properties and XRD profiles of the surface modified Sr–Fe composite oxides provided new insights into the role of the crystalline SrSO4 cluster (which was formed after the Sr–Fe composite oxide was modified with H2SO4 and HCl) in the enhancement of catalyst reusability and reactivity. The Koros–Nowak test for the sulfated/chlorinated Sr–Fe composite oxide revealed that the reaction rate of catalytic esterification was controlled by mass transfer of the reagents over the catalyst rather than the chemical reaction, indicating the high catalytic reactivity of the active sites present on the sulfated/chlorinated Sr–Fe composite oxide. The stability and reusability testing results indicated that the sulfated/chlorinated Sr–Fe composite oxide could be recycled 20 times without considerable reactivity loss.


The inclusion complex formation of α-cyclodextrin(α-CD) with various alcohols has been studied by means of titration calorimetry. The titration curve was analyzed successfully by the formation of a 1:1 hostguest complex, and the thermodynamic parameters were determined. The entropies of reaction are estimated from the statistical thermodynamics of molecules. However, the estimated values are found to deviate by an order of magnitude from the experimental ones. To resolve such a discrepancy, α-CD in solution is assumed to include a definite number(n) of water molecules which are replaced by a guest molecule with the progress of reaction. The entropies thus estimated depend extensively on the value of n, and a value of n is determined for each alcohol so that it reproduces just the experimental entropy. The resulting n values are nearly constant for various alcohols studied and are within a reasonable range expected from the data reported in crystal, supporting the model of interpretation.


Patent technology-effect matrix is very helpful for patent analysis but difficult to create. In addition to manual methods, most existing methods either use IPC and statistical classification or perform pattern matching algorithm to extract technology phrases and effect phrases. They are easy to ignore implicit semantic information and cannot mine deeply intelligence in patents. This paper retrieves patents in related domain, collect the patent texts, and apply semantic role labeling to create technology-effect matrix. Experiments show that semantic role labeling achieves satisfactory results and save manpower.


Plasmodium falciparum, the protozoan parasite causing falciparum malaria, is undoubtedly highly versatile when it comes to survival and defence strategies. Strategies adopted by the asexual blood stages of Plasmodium range from unique pathways of nutrient uptake to immune evasion strategies and multiple drug resistance. Studying the survival strategies of Plasmodium could help us envisage strategies of tackling one of the worst scourges of mankind.


Promotion refers to raising customer awareness of a product or brand, generating sales, and creating brand loyalty. It is one of the four basic elements of the market mix, which includes the four P's: price, product, promotion, and place. Promotion is also defined as one of five pieces in the promotional mix or promotional plan. These are personal selling, advertising, sales promotion, direct marketing, and publicity. A promotional mix specifies how much attention to pay to each of the five factors, and how much money to budget. Medan Area University has a promotional strategy to recruit new students in an effort to increase the number of students. The strategy is by utilizing the professional personnel of academicians and citizens of the campus, as well as the activities carries out through a variety of media, which is an appropriate strategy to achieve the goal of promotion. Its promotional activity has resulted in an increase in the number of new students significantly. Apparently, more diverse promotional activities have increasing the results obtained.

A study was conducted on time domain refractmeter(TDR) and time domain transmission(TDT) to explore determination accuracy of soil water content.Through simulated experiments,soil water content of the saline soil were calibrated and analyzed under different soil bulk density and salinity levels.The results showed that the results of soil water content determination by TDR and TDT determination and method of drying soil reached extremely significant level under different soil bulk density.The results of soil water content determination by TDR and TDT determination and method of drying soil reached extremely significant level when soil salt content was 2 g kg-1.TDR determination readings disappeared when soil salt content was 12 g kg-1,On the contrary,TDT determination readings was rational,and reached extremely significant level.Therefore,soil water content accurately was determined by TDT under the saline soil of less than 12 g kg-1.


A simpler novel process for extracting roads is outlined in this paper. The procedures which were adopted for checking the consistency of semantic labelling is described. And it discusses the extent to which findings should influence the database model and concludes by summarizing the findings.


Although human–robotic interaction is a rapidly burgeoning area of study within education, and social robots are being widely tested for use in schools, few studies have focused on early adolescent interactions with robots under actual classroom conditions.We introduced an autonomous, social robot ('Pepper') into a project‐based learning environment at a public elementary/middle school in order to see how long‐term exposure to a robot in a project‐based classroom affected student conceptions of robots.We conducted unstructured classroom observations, focus‐group interviews with students, and took videos of students interacting with the robot at key points in the project. We engaged in joint coding and memo writing to summarize key themes.Our results showed the limitations of these social robots as interactive educational technology, but also revealed the complexity of young adolescent beliefs about robots as social actors. Although current technology limits the ability of robots to be widely deployed in public‐school classrooms, skillfully designed interventions using social robots have the potential to motivate and engage students.Exposure to the robot stimulated students to discuss robots as social actors, raised issues about gender identification of artificial agents in the classroom, and stimulated discussion on what constitutes a social being. The initial novelty of the humanoid robot enhanced engagement with the longer‐term project and also challenged teachers to be more reflective and flexible in planning the project.


Abstract. The aim of this study was to show the effect of orientation on producing ellipses of various eccentricities. Ten right-handed adults were required to reproduce eight series of 84 ellipses on a graphic tablet at spontaneous speed. These ellipses varied according to seven eccentricities, corresponding to a relative phase (RP) between two abstract orthogonal oscillators varying from 0° for a line to 90° for a circle, and twelve orientations, the long axis of the ellipses varying between 0° and 180° with respect to the horizontal. Results confirmed the preference for 3 eccentricities (0°, 45° and 90° RP), a line, an ellipse of intermediate eccentricity, and a circle, respectively. Apart from the circle, insensitive to orientation by the definition, the results showed that when orientation became a cogent constraint, as movements were in the 10 o'clock direction, line drawing (0° RP) increased in variability and the intermediate ellipse (45° RP) was attracted towards a circle (90° RP). Results are interpreted in terms of coalition between orientation effects due to biomechanical constraints of wrist and fingers and eccentricity effects due to preferences arising from the non-linear coupling between the effectors.


Forty White Leghorn hens were caged individually in a 7.3 × 7.3 m shelter at the Pennsylvania State University Poultry Research Farm. The shelter contained 2 banks of single deck, double row cages (46 × 46 × 30 cm) divided by a 2.3 m aisle, 20 cages/bank. On 22 Jul '85, all 22-week-old hens were infested with northern fowl mites by placing mite-infested feathers into vent feathers of the uninfested hens. Hens were reinfested 3-4 times prior to treatment. Twelve hens with the highest mite population densities were selected and randomly placed into individual cages in one bank of the shelter. All other cages in that bank were emptied. On 22 Jan '86, 6 hens were randomly selected and sprayed with 40 ml of B-Exotoxin (1,000 ppm) with a 250 ml chromotography sprayer into the vent and tail area. The remaining 6 hens were sprayed with 40 ml of distilled water to serve as controls. Mite population density estimates were made weekly for 10 weeks post-treatment with the following visual rating scale: 0 = 0 mites/bird; 1 = 1-2 mites; 2 = 3-9 mites; 3 = 10-31 mites; 4 = 32-99 mites; 5 = 100-315 mites; 6 = 316-999 mites; 7 = 1,000-3,159 mites; 8 = 3,160-9,999 mites; 9 = 10,000-31,586 mites; and 10 = greater than 31,586 mites/bird


Purpose: This study seeks to design change management model for Iranian academic libraries. Methodology: Qualitative approach and Delphi method were employed to design change management model for Iranian academic libraries. Delphi technique was used in three rounds and initially 22 experts participated in the test. The change management model yielded for Iranian academic libraries consisted of five main stages as follows: 1) review of current status; 2) analysis of users; 3) programming/planning; 4) implementing the change; 5) maintenance of change achievements. Several activities have to be carried out at each stage. Findings: This model makes the directors of academic libraries and librarians familiar with concepts of change management and encourages them to apply this approach to academic libraries; this strategy leads to improvement in change implementation in academic libraries together with a decrease in costs and redundancies. Future studies may include trial implementation of the proposed model in different academic libraries, providing tools necessary for activities of the model, studying the order and succession of these activities, and determining the time required for performing each activity. Originality/Value: Although change management has been employed in some institutions, it is the first time of designing such a model for academic libraries. Therefore, Iranian academic libraries can make benefit from this model for management and implementation of change.


The development of a benthic filamentous greenalgal community formed by Spirogyra sp. has been observed in the littoral zone with gravel in rhe north basin of Lake Biwa, Japan (NOZAKI er al. 1998, NüZAKI 1999). The Spirogyra community begins to propagate in May, and its biomass reaches a maximum from early June to mid-July. However, rhe community of Spirogyra rapidly decreases in late July (NoZAKI 200la). The cause of the Spirogyra decline in summer has never been determined. The proximate factors controlling benthic algal biomass can be divided into rhose regulating the processes of growth and metabolism, and rhose regulating the counteracring processes of biomass loss (BIGGS 1996). Temperature, light and nurrients influence growth and metabolic rates, and disturbance and grazing are the main factors leading to biomass loss. In rhe littoral zone of Lake Biwa, wave action as a disturbance factor is minimal in summer (NAKAJIMA 1980), and active grazers on Spirogyra have never been found (MITSUHASHI & NoZAKI unpublished data). These resulrs indicate rhat rhe factors promoting biomass loss do nor affect rhe summer decline of the Spirogyra community. Thus, in order to understand the Spirogyra decline, the factors regulating growrh and metabolism have to be examined. Temperature is one of the most important environmental influences on the growrh and metabolism of freshwater benthic algae. GRAHAM er al. (1995) reporred that the optimum warer temperature affecring rhe photosynthesis rate of Spirogyra sp. collected from Surrey Lake (USA) was 20-25 oe, and thar the photosynthesis rate rapidly decreased at 30-35 oe. They suggesred that rhe water temperature is an important factor in the summer decline of Spirogyra in Surrey Lake. Water temperature in rhe littoral zone of Lake Biwa frequendy reaches 30-33 oe at noon from July to August (NoZAKI 1999). If the resulrs of GRAHAM er al. (1995) are confirmed by those of Lake Biwa, summer warer remperature may act negatively on rhe growrh and metabolism of Spirogyra. In this study, rhe effect of water temperature on the summer decline of Spirogyra is examined, on the basis of photosynthetic activities obtained from field and experimental studies.


Objective
To investigate the comprehensive treatment and prognosis of primary intracranial choriocarcinoma of familial tendency.

Methods
Two whole sisters admitted to the Department of Neurosurgery, Yuquan Hospital, Tsing Hua University in June 2013 and confirmed as primary choriocarcinoma in sellar region by pathology were summarized. Their ages of onset were 9 and 11 respectively. The lesion site was in the sellar region. The preoperative tumor markers suggested abnormally increased β-HCG; their choriocarcinomas were resected after giving a course of ICE chemotherapy. The elder sister was operated via interhemispheric fissure-corpus callosum-between the fornices approach and the younger one was operated via crown cut-frontal anterior longitudinal fissure approach. They underwent regular chemotherapy after surgery and did not undergo radiotherapy.

Results
The 2 choriocarcinomas achieved near-total resection under the microscope. They all recovered well after surgery and did not have serious complications in saddle regions, and both were pathologically confirmed as choriocarcinoma. The examination before discharge showed that β-HCG turned to negative. They had 5 regular chemotherapies, and they were followed up to now and their choriocarcinomas did not recur.

Conclusions
Primary intracranial choriocarcinoma is high malignant and it is rare in clinical practice. Its familial predisposition onset is rarely reported. As long as the diagnosis is clear, the use of regular chemotherapy and appropriate surgical approach may achieve a satisfactory efficacy. If it can be studied from genomics, it might be able to achieve a breakthrough on the basis of primary intracranial choriocarcinoma.

This investigation involves the ab initio quantum mechanical study of the decomposition and reactivity of the CHF2CF2CF2OCH2O• radical that is formed from CHF2CF2CF2OCH3 (HFE-356pcc3). The geometries of the reactants, products and transition states were optimised at the B3LYP and B3PW91 levels of theory using the 6-311G(d,p) basis set. Five important pathways for the decomposition and reactivity of CHF2CF2CF2OCH2O• were investigated: (1) reaction with atmospheric O2, (2) reaction with atmospheric •OH radical, (3) C–O bond cleavage, (4) H elimination and (5) the migration of hydrogen from carbon to oxygen and then C–O bond cleavage, with energy barriers of 4.4 (5.0), 11.9 (12.4), 17.0 (17.3), 20.4 (19.4) and 32.2 (32.6) and 15.5 (16.7) kcal mol−1 respectively [values in parentheses are for the B3PW91/6-311G(d,p) level of theory]. Rate constants were calculated by utilising canonical transition state theory in the range 200–400 K and the corresponding Arrhenius diagrams have been plotted. The results showed that the rates of decomposition and reaction increase with increasing temperature. Also, between 200 and 306 K, path (1) has the highest rate constant: moreover, it was concluded that reaction with atmospheric O2 is the dominant pathway for the consumption of CHF2CF2CF2OCH2O• in the atmosphere. An intrinsic reaction coordinate calculation was performed to confirm the existence of a transition state on the corresponding potential energy surface.


Utilization of CO2 for the synthesis of fine chemicals and pharmaceuticals has attracted tremendous attention. In fact, reductive transformation of CO2 is also an interesting approach in this direction. Obviously, using hydrogen as a reducing agent is the most promising pathway for this reductive transformation. However, alternative to hydrogen, hydrosilanes have been also in the forefront due to their ready availability, nontoxic nature and easy handling procedure. Based on all this information, this work summarizes the recent applications of hydrosilylation of CO2 using different catalysts such as metal catalysts, organocatalysts, and heterogeneous catalysts.


Residual free water expected to remain in a Multi-Canister Overpack (MCO) after processing in the Cold Vacuum Drying (CVD) Facility is investigated based on three alternative models of fuel crevices. Tests and operating conditions for the CVD process are defined based on the analysis of these models. The models consider water pockets constrained by cladding defects, water constrained in a pore or crack by flow through a porous bed, and water constrained in pores by diffusion. An analysis of comparative reaction rate constraints is also presented indicating that a pressure rise test can be used to show MCO`s will be thermally stable at operating temperatures up to 75 C.


N-Trifluoroacetyladriamycin-14-valerate (AD 32) is an analog of doxorubicin whose chemico-physical characteristics are nontypical compared to the parent compound. Its most interesting feature is the lack of capacity to intercalate with DNA; thus, its mechanism of action as an antitumoral drug is still unknown. The N-trifluoroacetyl bond on the glycoside moiety is very stable and does not easily undergo enzymatic hydrolysis. Conversely, the valerate ester is split very rapidly by tissue and blood hydrolases. In this paper we present a kinetic study on AD 32, and we additionally follow the formation and disappearance of its metabolite, N-trifluoroacetyladriamycin (AD 41). Peak levels, areas under the curve, and beta-half-lives of AD 32 and AD 41 after an iv injection of 80 mg/kg of AD 32 to Lewis lung carcinoma-bearing mice are presented. The results indicated very rapid disappearance of AD 32 from blood and tissues, whereas AD 42 persisted for much longer. Moreover, all of the tissues taken into consideration were able to hydrolyze AD 32 to AD 41, suggesting that this compound plays an important role in the antitumoral activity of AD 32.

A presidential inaugural speech marks, formally, the beginning of a president's term of office in many countries. In such a speech, the head of state establishes his/her intentions as a leader. Presidents-to-be may also include social, economic and political remarks. This paper aims at analyzing the vocabulary in Barack Obama's two inaugural speeches in order to detect the major issues at these two historical moments for the American society. A corpus of 4051 words was compiled and consists of Obama's complete inaugural speeches. AntConc software was used to quantify the words most frequently chosen as well as the number of times each word appeared. It was noticed different lexical choices in both speeches when comparing the two frequency lists generated from them. The paper concludes that the content of the two speeches were influenced by different historical moments.

Not by a long shot. Among the 30 developed nations that make up the Organization for Economic Cooperation and Development (OECD), the United States ranks near the bottom on most standard measures of women's health. American women rank twenty-third in life expectancy, twenty-second in maternal mortality, and twenty-fifth in infant mortality (which is a sensitive indicator of maternal health) [1]. These international comparisons are often dismissed with the rationalization that our nation is more ethnically heterogeneous than nations at the top of the rankings, but even when the comparisons are limited to white women, we still place near the bottom of the rankings.


The present paper has attempted to examine determinants of small business(SMEs) presence in Japanese and UK manufacturing industries, using a cross-industry model. The results suggest that market structure elements have a definite influence on SMEs' share. This conclusion is consistent with the findings observed in the US and other European countries. The main results here are the following; (1) Concentration is negatively related to SMEs' share. (2) Capital intensity and requirements have a negative influence. (3) Scale economies have a negative association with SMEs f share. (4) RD it has a negative effect in the UK, while it has no effect in Japan. (6) Also, both industry size and growth have a different relationship between the countries. These factors have a significant effect in the UK. but the former has a negative effect, while the latter has a positive effect. On the other hand, these factors have no discernible effect in Japan. (7) The subcontracting has no definite influence on SMEs' share in Japan,

The S atom in the sulfonyl group has a distorted tetrahedral geometry. The two independent molecules in the asymmetric unit form two centrosymmetric dimers connected by intermolecular N—H⋯O hydrogen bonds between the amino and sulfonyl groups.


Urinalysis is not only widely employed in medical diagnosis but also suitable for household daily monitoring of personal health conditions. However, current urinalysis methods and instruments require more professional knowledge, while the sampling and treatment of urine samples are manual and inconvenient. In this work, a new-concept automatic urinalysis system is proposed to provide personal urinalysis services for home users. The system forms an eco-friendly intelligent toilet, which is of great significances in the future healthcare network. The basic strategy is to design a fixed supporting platform and various disposable urinalysis lab-on-chips with great expansibility and high flexibility. The intelligent device has multiple functions of automatic urine sampling, rapid on-chip detecting, auto-decontaminating and personalized health information technology (HIT) supporting, thus to provide a low-cost solution of automatic urinalysis services for both inpatients in hospitals and home-users. The structure of the urinalysis system logically resembles the frame with fixed smart cellphones and various mobile application programs. Besides, a biological lighting module is also designed to harvest the energy in wasted urine by continuous culturing vibrio fischeri, a luminescent bacterium. The integrated urinalysis system could create the possibility of remote medical services for home users, and meanwhile generates a new branch in the field of microsystem, which is entitled as 'HIT-oriented lab-on-chips'.


One pathological characteristic of Alzheimer's disease (AD) is extensive synapse loss. Presenilin 1 (PS1) is linked to the pathogenesis of early onset familial Alzheimer's disease (FAD) and is localized at the synapse, where it binds N‐cadherin and modulates its adhesive activity. To elucidate the role of the PS1/N‐cadherin interaction in synaptic contact, we established SH‐SY5Y cells stably expressing wild‐type (wt) PS1 and dominant‐negative (D385A) PS1. We show that the formation of cadherin‐based cell–cell contact among SH‐SY5Y cells stably expressing D385A PS1 was suppressed. Conversely, wt PS1 cells exhibited enhanced cell–cell contact and colony formation. Suppression of cell–cell contact in D385A cells was accompanied by an alteration in N‐cadherin subcellular localization; N‐cadherin was retained mainly in the endoplasmic reticulum (ER) and cell surface expression was reduced. We conclude that PS1 is essential for efficient trafficking of N‐cadherin from the ER to the plasma membrane. PS1‐mediated delivery of N‐cadherin to the plasma membrane is important for N‐cadherin to exert its physiological function, and it may control the state of cell–cell contact. © 2003 Wiley‐Liss, Inc.


In numerical linear algebra, we have a number of iterative methods based on Krylov subspace method. GPBiCG AR method which we have proposed is an attractive alternative for solving linear equations with nonsymmetric coefficient matrix. In this paper, we consider a variant of GPBiCG AR method with reduction of computational costs per single iteration. We refer to it as GPBiCGAR 2 method. Through numerical experiments, we will verify improvement of convergence rate of the variant with safety convergence.


Since ARCH and GARCH models are presented, more and more authors are interested in the study of volatilities in financial markets with GARCH models. Method for estimating the coefficients of GARCH models is mainly the maximum likelihood estimation. Now we consider another method—MCMC method to substitute for maximum likelihood estimation method. Then we compare three GARCH models based on it. MCMC method developed based on Markov chain, which is one kind of straggling time and state random process with no offspring imitates. It attracts extensive attention because of its applications in many fields. In this article, we will compare GARCH models based on different distributions with MCMC method. At last we have the conclusion that both in uni-variable case and binary variable case, GED-GARCH is the best model to describe the volatility compared to other two models, and we will provide the application of binary GED-GARCH models in forecasting the volatility in China's stock markets.


The stiffness properties of a finite sized model element of a plate under plane stress are presented. The mathematical model is a piece of the material itself and not a configuration of bars that replace the material. It is shown that an additional deformation condition should be specified instead of an arbitrary arrangement of bars. An example shows that this extra condition considerably increases the accuracy of the model and so reduces the number of degrees of freedom required to approximate the continuous system. A system of bounding the deflection under a single load is shown by assigning values to a free parameter. Thus, the maximum error is known and can be reduced without going to a fine grid.

Objective: This study investigated perceptions and misinformation regarding COVID-19 mitigation measures at school board meetings (SBM) held within the five largest school districts in Tennessee. Methods: Participants' commentaries were extracted from SBM recordings that were uploaded to YouTube from August through September 2021. Data were examined using qualitative analysis. Results: Several SBM attendees expressed concerns that mask mandates were unconstitutional and infringed on personal liberty. Others described significant comorbidities, adverse psychosocial impacts, mental health disorders, learning difficulties as well as worsening socioeconomic, nutritional, racial, and educational disparities. Debunked claims that portrayed masks as being ineffective and responsible for some children's respiratory infections, socio-behavioral changes, learning loss, and breathing difficulties were disseminated. Fatigue and burnout, limited paid leave for quarantining, low staffing numbers as well as mixed messaging, and lack of support from school districts was cited by educators. Conclusion: To bolster public health response to future pandemics, health officials/policymakers should implement health promotion preparedness strategies and policies that support safe/effective in-person learning.Innovation: We proposed recommendations to respond to future pandemics using four overarching themes: implement evidence-based safety measures;address misinformation with tailored, clear, and timely messages;prioritize student support services and in-person learning;and facilitate engagement of relevant stakeholders.


This paper describes an improved analytical F-N channel erase and V/sub T/ distribution model by including both process and cell parameters. This model is also able to predict the tightening of V/sub T/ distribution after using F-N soft reprogramming techniques. The accuracy of the model is verified by measured V/sub T/ curves and distribution. This new model provides a simple and useful tool for cell optimization and reliability design-in by accurately correlating V/sub TE/ distribution to physical parameters of process and memory cell.


The results presented in this paper refer to a fatigue life study of plate T joints predominantly loaded in bending. Crack initiation life was taken into account in the analysis using recently developed models. The crack propagation model was based in the Mk factor computed with the Glinka weight function method. The influence of the ratio L/B (leg to leg distance over main thickness) on the Mk values was obtained. The Mk results were also obtained as a function of the radius of curvature at the weld tow which is the controlling parameter of the Mk results. Crack aspect ratio curves (a/c against a/B) were also derived and compared with experimental observations. The residual stress distribution was also analysed and an assessment was made of their values in the a/c against a/B curves. The fatigue crack propagation life was computed by integration of Paris law type. A semi-elliptical crack growth model was assumed with Mk the magnifying factor of the basic K equation. A comparative study is also presented of the crack initiation and crack propagation contributions for fatigue life. This could help the designer to define the most appropriate model for his fatigue life problem. Theoretical predictions of fatigue life (crack propagation plus crack initiation) were made and compared against experimental results in the literature. Results were obtained for different main plate thicknesses and good agreement was obtained.


We have simulated noncontact atomic force microscopy on benzene-molecule-adsorbed Si(001) surfaces using the density-functional based tight-binding calculation. We show that three adsorption structures, namely, the standard butterfly, the tight bridge, and the twisted bridge, can be distinguished from topographic line profiles along directions perpendicular and parallel to the Si dimer row. The atomic configuration does not change markedly during the noncontact atomic force microscopy line scan even when the tip almost contacts the surface, which suggests that a stable adsorbed structure hardly changes to another stable structure at zero temperature.


At present, within the formation of Health Human Resources, three pedagogical models could be identified: transmission pedagogic that states ideas as well as knowledge are the most important topics regarding education, thus the student must receive what the "instructor", or the textbooks. Behavioral pedagogic with emphasizes in training, empirical and operative manifestations of knowledge, attitude and skill improvement. Finally, trouble pedagogic, which states that the student skill is the main point for social transformation in order to find out actual problems and seek for an original as well as creative solution. Thus, the ability that must be developed is to ask relevant inquiries in any case, to understand THE PROBLEM and be able to solve it properly. This model is based upon the constructive theory, where the student builds up his or her own knowledge, thus it is not important to lead him to repeat contents. According to this proposal we privilege this model in health; thus, throughout the use of the Bustos Operative Didactically Pattern, didactically tools were proposed to be applied through the formation of health staff. This model includes five steps: (1) Life experiences; (2) Reflection; (3) Documentation; (4) Application; and (5) Ampliation. The proposal does not include predetermined programs but the adjustment to institutional, local as well as national reality.

We investigate the effect of long-range Coulomb interaction on the quasiparticle properties and the dielectric function of clean three-dimensional Weyl semimetals at zero temperature using a functional renormalization group (FRG) approach. The Coulomb interaction is represented via a bosonic Hubbard-Stratonovich field which couples to the fermionic density. We derive truncated FRG flow equations for the fermionic and bosonic self-energies and for the three-legged vertices with two fermionic and one bosonic external legs. We consider two different cutoff schemes---cutoff in fermionic or bosonic propagators---in order to calculate the renormalized quasiparticle velocity and the dielectric function for an arbitrary number of Weyl nodes and the interaction strength. If we approximate the dielectric function by its static limit, our results for the velocity and the dielectric function are in good agreement with that of A. A. Abrikosov and S. D. Beneslavski\ifmmode \breve{\imath}\else \u{\i}\fi{} [Sov. Phys. JETP 32, 699 (1971)] exhibiting slowly varying logarithmic momentum dependence for small momenta. We extend their result for an arbitrary number of Weyl nodes and finite frequency by evaluating the renormalized velocity in the presence of dynamic screening and calculate the wave function renormalization.


VLF-EM method and radioactivity prospecting were carried out in Bandai-san Caldera. The distribution and characteristic of fault system in Bandai-san Caldera occurred in 1888 eruption were made clear.The results of these prospecting show that the fault systems is divided into three directions; north-south direction, northeast direction and east-northeast direction. The most prominent fault identified by this study was the north-south fault located within the central portion of the caldera. The northern extension of this fault appeared to be connected to the eastern scarp of Avalanche valley and the southern extension appeared to be under the peak of Kobandai-san which was destroyed by a volcanic eruption in 1888. Northeast and east-northeast faults cut across the caldera.Considering the results of this study and other geological informations, it may be inferred that the northsouth fault was formed by intrusion of north-south dike. The directions of northeast and east-northeast fault are concordant with the ridge direction of Kobandai-san. The feature suggests that the northeast and the east-northeast fault are gravity fault caused landslide plane.


We experimentally demonstrate the use of a long period grating to promote selective coupling between two cores of a 4-core fiber. The device was successfully tested for a 200 Gb/s DP-16QAM signal transmission.


lower haemoglobin compared to the non-transfused group. After adjusting for these covariates, transfusion was still associated with a 28% increase in median time to extubation (risk ratio 0.71; 95% confidence interval 0.62 to 0.81; P 0.001). Discussion: In this review of our audited practice, we observe that transfusion delayed extubation. It is therefore possible that transfusions may hinder the process of weaning from mechanical ventilation. Reference: 1 Habib RH, Zacharias A, Engoren M.
