Practically all the ground water of economic importance in the Truckee Meadows area, an alluviated intermontane basin in western Nevadr, is in the valley fill, which consists of unconsolidated and partially consolidated sedimentary deposits. The Mesozoic and Cenozoic consolidated rocks of the mountains bordering the valley contain some water in fractures ani other openings, but they have virtually no interstitial permeability. The permeability of the valley fill is extremely variable. The Truckee Formation, which is the oldest deposit of the valley fill, yields very little water to well". Permeable lenses of sand and gravel in the valley fill that are younger than the Truckee Formation yield moderate to large amounts of water to weir*. The estimated average annual recharge to and discharge from the groundwater reservoir is 35,000 acre-feet. About 25,000 acre-feet of the recharge is from the infiltration of irrigation water diverted from the Truckee River. Most of the discharge is by evapotranspiration and by seepage to ditches and streams. Some water in the area is unsuitable for many uses because of its poor chemical quality. Water in the Steamboat Springs area is hot and tas high concentrations of chloride and dissolved solids. Both water draining areas of bleached rock and ground water clowngradient from areas of Peached rock have high concentrations of sulfate and dissolved solids. Surface water of low dissolved-solids content mixes with and dilutes some highly mineralized ground water. Increased pumping in discharge areas will help to alleviate waterlogged conditions and will decrease ground-water losses by evapotranspiration. Increased pumping near the Truckee River may induce recharge from the river to the ground-water system. INTRODUCTION PURPOSE AND SCOPE OF THE INVESTIGATION In the Truckee Meadows area, the second largest population center in Nevada, practically all water for irrigation and most water for municipal supply is diverted from the Truckee River. During S2 CONTRIBUTIONS TO THE HYDROLOGY OF THE TJJSTTED STATES periods of drought, as in 1959-61, deficient precipitation and runoff cause serious water shortages. The rapid increase cf the area's population during the past two decades has caused an increased demand for water in the valley. Hence, water shortages during future periods of drought may be more serious. On the average, surface water diverted into the valley for irrigation exceeds in amount the water beneficially used by crops. As a result, some of the land formerly used for agriculture in the northeastern part of the valley is waterlogged; that land is not suitable for urban development. In some parts of the valley, ground water is unsuitable for many uses because of its poor chemical quality. Domestic wells and some large-capacity wells developed for municipal use have been abandoned because of excessive amounts of certain dissolved constituents in the water from these wells. Also, attempts to develop thermal water for generating power and for heating homes and greenhouses generally have been unsuccessful owing to the poor chemical quality of some of the water. To obtain some of the data needed to utilize the water resources of the valley effectively, the U.S. Geological Survey in cooperation with the Office of the Nevada State Engineer (now a division of the Nevada Department of Conservation and Natural Resources) began in 1950 a study of several aspects of the ground-water hydrology of the area. The study was intended to stress those aspects of the ground-water system that bear directly on the hydrolo^ic problems as described in the preceding text. To this end, the geology of the area was mapped with particular emphasis on the occurrence and water-bearing properties of the unconsolidated deposits of the valley fill. Seepage measurements were made along streams and irrigation ditches to determine areas of ground-water recharge and discharge and to obtain a rough approximation of the average annual recharge and discharge. An intensive water-quality study was undertaken. Water samples were obtained from selected wells, streams, and ditches. Waterquality data also were obtained from several government agencies. The content of this report is limited mainly to the aforementioned studies. During the investigation it became apparent that other detailed studies would be necessary to completely define the hydrology of the valley. For example, because the ground-water system is closely related to the surface-water system, comprehensive and coordinated ground-water and surface-water studies are needed. A detailed analysis of the flow of the Truckee River and tributary streams would help define more accurately the ground-water reTRUCKEE MEADOWS AREA, WASHOE COUNTY, NEVADA S3 charge and discharge and the possible uses of water in the valley. In 1961, gaging stations were constructed along Galena, Whites, Steamboat, and Hunter Creeks. Data obtained at these station and at stations along the Truckee River should be useful in future more comprehensive studies. LOCATION AND GENERAL FEATURES OF THE AREA The Truckee Meadows area is one of a series of north-trending basins in northwestern Nevada that are bordered on the west by spurs of the Sierra Nevada and on the east by the Virginia Range and its southward extension, the Pine Nut Range. In this report, the term "Truckee Meadows area" defines the topographic basin bordered on the west by the Carson Range, which is a spur of the Sierra Nevada, on the east by the Virginia Range, on the north by units of these two ranges, and on the south by Pleasant Valley. Pleasant Valley is drained by Steamboat Creek, which flows northward into Steamboat Valley. Steamboat Valley is considered part of the Truckee Meadows area in this report. Spanish Springs Valley drains into the Truckee Meadows area from the north. Reno and the adjoining city of Sparks are the major communities in the Truckee Meadows area. The total population in the area in 1960 was about 80,000. The Truckee River, the principal stream in the area, heads in the Sierra Nevada south of Lake Tahoe and about 40 miles southwest of Reno, and it discharges into that lake near its southern shore. The river discharges from the northwestern margin of the lake and flows northward and northeastward through a steep-walled canyon to the city of Verdi, Nev., about 7 miles west of Reno. From there, the river flows eastward out of the highlands of the Sierra Nevada, follows a meandering course eastward through the Truckee Meadows area, and discharges from the valley through a narrow, steep-walled canyon in the Virginia Range. It next flows eastward to the city of Wadsworth, about 25 miles east of Reno, thence northward for about 15 miles and discharges into Pyramid Lake. Steamboat Creek is the Truckee River's principal tributary in the study area. It enters the Truckee Meadows area through a bedrock constriction at the southern end of Steamboat Valley, receives ephemeral flow from Whites, Thomas, and Dry Creeks, and flows northward, discharging into the Truckee River near tH gap in the Virginia Range. Most other streams in the area are ephemeral, but they are used locally as sources of irrigation water. The larger ephemeral streams drain the Carson Range ard are, 723-135 64 2 S4 CONTRIBUTIONS TO THE HYDROLOGY OF THE UNITED STATES from north to south, Hunter, Alum, Evans, Dry, Thomas, Whites, Jones, and Galena Creeks. A network of ditches supplies irrigation water to farms and ranches in the area. The larger ditches that carry w.ter from the Truckee River include Steamboat, Last Chance, Lake, Cochran, Scott Ranch, and Pioneer ditches along the western margin of the valley, and the Highland and Orr ditches along the northern margin of the valley. The Orr ditch brings water to Spanish Springs Valley and returns excess water to the Truckee River by way of the North Truckee drain. Some of the water diverted from ditches along the western margin of the valley returns to the Truckee River by way of Boynton Slough and Steamboat Creek. The Sierra Nevada is a major factor influencing the climate of the area. Moisture-laden air moving eastward is forced aloft by the mountains. The air cools and condenses, resulting in heavy precipitation in the mountains, locally more than 40 inches per year. Normally, the abundant precipitation in the mountains supplies plentiful surface water to the study area. The Truckee Meadows area is in the rain shadow of the Sierra Nevada; consequently, precipitation on the valley floor is small, and the climate is arid to semiarid. As a result, it is necessary to irrigate nearly all crops raised in the area. The average annual precipitation in Reno during the period 18711959 was 7.14 inches. The maximum annual precipitation, 13.73 inches, occurred in 1890, and the minimum annual precipitation, 1.55 inches, occurred in 1947. More than half of the annual precipitation usually occurs from December through March (table 1). TABLE 1. Average monthly precipitation at Reno, Nev., 1871-1959 [From U.S. Weather Bureau records]


The objective of this work was to evaluate the growth and production through statistical models, under the variables of diameter at 1.30m, total height and volume of a stand of Pinus caribaea var. caribaea at 35 years old, not thinned, located in the municipality of Nova Marilândia, Southwest region of the state of Mato Grosso. Diameter data at 1.30m high and total height data were collected in 31 temporary plots with 900 m² (30m x 30m) and 60 dominant and codominant trees were felled. Of these, 31 were rigorously scaled using the Smalian method and trunk analysis was performed in 29. Fourteen volume equations, local productivity classification were adjusted, in addition to the adjustment of nine growth and forest production models. The accuracy verification of the estimates of all the models tested was given by the adjusted Coefficient of determination (R²adjus.); the Standard error of estimates (Syx%); and the Error percentage (Error%) and graphic analysis of residues. To determine the volume of Pinus caribaea var. caribaea, the best adjustment was obtained with the Schumacher-Hall model. The growth and production models suitable for P. caribaea for the diameter estimates were Hoerl's, and for height and volume were Moissev's. In the classification of local productivity, 3 site classes were determined, ranging between 18 and 26 m at the index age of 35 years with the Moissev model.


The development of the theory and methodology of the humanitarian education and science is impossible without the humanities. What is special is that problems of improving the subject and managing information and knowledge are determined by the substance of man and humanity matter through which things, organizations, systems and technologies are created, transformed and improved. The report presents and analyzes some issues and problems of the humanistic paradigm, as well as the nature of information and knowledge, and their application in research, education, management and development of systems and technologies in contemporary socities.


We report on the feedback stabilization of the zero-phonon emission frequency of a single InAs quantum dot. The spectral separation of the phonon-assisted component of the resonance fluorescence provides a probe of the detuning between the zero-phonon transition and the resonant driving laser. Using this probe in combination with active feedback, we stabilize the zero-phonon transition frequency against environmental fluctuations. This protocol reduces the zero-phonon fluorescence intensity noise by a factor of 22 by correcting for environmental noise with a bandwidth of 191 Hz, limited by the experimental collection efficiency. The associated sub-Hz fluctuations in the zero-phonon central frequency are reduced by a factor of 7. This technique provides a means of stabilizing the quantum dot emission frequency without requiring access to the zero-phonon emission.


Cybersecurity contains three basic features such as confidentiality, integrity and availability. Data confidentiality ensuring by encryption has faced quantum computing threat, but this problem can be solved by using post-quantum cryptography and / or quantum cryptography (quantum key distribution). For cryptographic applications statistical properties of the generated pseudorandom sequences should not be differ from random sequences. To determine such properties a number of statistical testing methods are used, but they all are focused on the evaluation of binary sequences. In quantum cryptography there are some protocols with Q-trits (qutrits), but these sequences cannot be assessed effectively by binary statistic methods. From this position in the paper quality assessment approach for Q-trits pseudo random number generators and formed sequences was proposed. Also the experimental study of proposed approach (in comparison with NIST STS) was carried out. Given results show that NIST STS technique cannot be used to evaluate the quality of the Q-trit sequences and generators, but developed method is suitable to use in practice for evaluating Q-trit sequences (generators) quality.

Abstract Debate surrounds the process through which a rock located beyond the frontier of an Aboriginal Reserve, known to White Australians as Ayer's Rock and Aboriginal Australians as Uluru, became the focal attraction within the first Outback national park during 1958. Contrary to the view that it was by chance that Uluru was transformed into a tourist playground rather than an Aboriginal State, this article argues that the Australian National Travel Association (ANTA) actively drew Uluru into tourism's grasp with a net of meaning and rites to commemorate the achievements of a new pioneering nation. Focusing on the brokerage of travel traditions and tourist gazes to set tourists in motion to honour explorers, prospectors and naturalists atop Uluru, it traces ANTA's launch of The Centre as a tourist destination. This development characterised the first phase in the struggle over the 'heartland' of Australia. The second concluded when Anangu's customary rights to Uluru were restored during the 1980s. Today, Anangu seek to balance tourism with self-determination. I conclude by outlining present efforts to dismantle climb-based touristic expectations and behaviours formalised by ANTA, and argue that while tourism has been a force for conflictual change, it might foster conciliation between former colonising and colonised peoples.


Content analysis is a research method that uses a set of procedures to make valid inferences from text. This is used extensively in media communication. Krishidarshan is an agriculture based television show of Doordarshan, with various segments including live-phone-in programmes. A study was carried out to perform content analysis of live-phone-in television programmes of Krishidarshan in West Bengal from 2007-2012. For this, secondary data was accessed from telecast register of Krishidarshan , Doordarshan Kendra Kolkata. Sector specific classification namely agriculture, animal husbandry and fisheries, was done. Experts' involvement from different organisations was also recorded. Appropriate descriptive statistics and parametric tests were used. It was found that majority of programmes were related to agriculture (86.98%) followed by animal husbandry (7.37%) and fisheries (5.65%). Results of analysis of variance revealed significant difference between number of programmes under each sector. Under agriculture related topics, programmes on agriculture schemes were highest with 9.04% and for animal husbandry, programmes related to poultry and duck farming were highest with 26.67%. In case of fisheries, topics related to fish health and pond management were highest (43.8%). Majority of experts were from Department of Agriculture in case of agriculture based programmes and from State Agriculture Universities for animal husbandry and fisheries.


In rats pretreated with reserpine and nialamide the effect of sympathetic stimulation, 20 and 6 imp/sec, on the uptake of exogenous noradrenaline was studied in the adrenergic nerves of the iris and salivary glands using fluorescence and biochemical methods, respectively. The uptake of noradrenaline was smaller on the stimulated than on the unstimulated side. The results are discussed with respect to factors such as changes in the circulation, transmitter release during the stimulation, and the presence of an intermittent blockade of the membrane pump during the impulses. It is suggested that the latter mechanisms might be of some physiological importance.


A remote sensing approach was adopted to determine environmental flow requirements for wetlands in the Lower Darling River. The regulation of river flows by the Menindee Lakes Storage has altered the natural flow regime in the river and is likely to be affecting the health of both the river and its wetlands. Landsat Thematic Mapper (TM) images corresponding to four flood events (1989, 1990 and two in 1996) were analysed and a relationship between river flow heights and wetland inundation was established. Wetlands were classified according to broad commence-to-flow river discharges. The study concluded that 13 000 Ml d-1 (megalitres per day) at Weir 32 would inundate approximately 50% of the wetlands along the Lower Darling River, this figure being 10 000 Ml d-1 less than estimated in a previous study.


The SKB scores already well on the components of the CCM, but that does not mean there is no room for improvements in each component. The SKB must focus more on activating patients and implement self-management in the care process. The main risk is about variation of care. To reduce the variation in the care process for COPD patients in SKB, improvements generally have to deal with structure and uniformity


This paper deals with pharmaceutical supply-chain network design considering time periods. Due to the importance of healthcare management in the forward side of supply chain and increasing amount of waste in recent years, we address both forward and back side flow of pharmaceutical network in this paper to satisfy patients' need and control the useless materials to achieve environmental considerations. We proposed a seven echelon closed-loop network with capacitated facilities in which time periods, transportation mode and production technology are included. It is noteworthy that inspection at distribution centres is applied to prevent tainted material delivery on the forward side. These useless materials have been sent to collection centres to be disposed of in the best way. Furthermore, the model of this paper determines the number of production centres, distribution centres, collection centres, production technology, transportation mode and the best way in the process of waste disposing and tries to satisfy consumer's need on time and minimise the network costs. Some numerical examples are proposed to explain the results.


Abstract Electrical characteristics of metal-insulator-semiconductor (MIS) capacitors of a variety of ferroelectric materials like lead zirconate titanate (PZT), lead titanate (PT) and barium magnesium fluoride (BMF) on p-silicon have been studied. PZT was deposited by r.f. magnetron sputtering from a composite target and PT from co-evaporation. The films were annealed in oxygen atmosphere in the temperature range 550–700°C for various times. PZT and PT films which are directly deposited on silicon showed low effective dielectric constant.10 For normal applied bias voltages (±5 V), the C-V curves did not show significant hysteresis. The effective dielectric constant was improved significantly by the incorporation of a buffer layer. BMF film was deposited in ultra high vacuum on a heated substrate and the film was encapsulated by a zirconium oxide layer. The C-V curves for these MIS capacitors shows hysteresis and the direction of hysteresis corresponds to ferroelectric polarization.


Background
Qiangji Jianli capsule or Qiangji Jianli Tang is a drug consisting of some medicinal herb, which has been used in the treatment of MG for many years. Some research suggests this drug can promote the contraction strength of the diaphragm muscle, which plays an important role for the ventilation of lung. Based on this theory we raised the hypothesis that preoperative medication of Qiangji Jianli method may decrease the incidence of postoperative myasthenic crisis. Neutrophil to lymphocyte ratio (NLR) is used as a marker of subclinical inflammation. Some researchers suggested that increased preoperative NLR is associated with poor prognosis of various cancers. The purpose of this study is to evaluate that if the preoperative use of Qiangji Jianli method has a meaningful value in the prevention of postoperative myasthenic crisis. We also will explore the dynamic change of the NLR during the perioperative period.


Though there are significant researches on optimization of I/O performance in virtualized environments, a study on high-performance network I/O over multicore-based full virtualized systems has not been done thoroughly. The legacy process scheduler cannot support virtual machines that perform networking efficiently with respect to the network bandwidth. To cope with this problem, we suggest a dynamic virtual machine scheduling for high-performance network I/O virtualization. The suggested scheme schedules virtual machines to optimal core by considering the cache layout of muticore processors and shows that it can improve the network bandwidth up to 97% compared with the legacy scheduler.

There is a close relation between exploitation of coal mine and groundwater resources.The layer of coal is usually border upon the aquifer of groundwater,which not only influence the quantity and quality of groundwater resources,but also destroy dynamic balance and eco-environment of water and result in a series of ill result.According to characteristics of environment influence and the newest development trend of environment protection in the course of coal exploited engineering,the article briefly puts forward some relative issues about evaluation of environmental influence of groundwater,about groundwater environment owing to coal exploitation as well as some issues about floor sinking and influence in vegetation sight owing to dredging up groundwater in the coal area.


Andaman and Nicobar Islands, the emerald Islands, sprinkled in the Bay of Bengalare vulnerable to disaster. These Islands being a seismological vulnerable are prone tohydro meteorological disasters such as floods, cyclones, storm surges and cloud bursts. TheIslands fall in cyclogenesis zone having significant number of cyclone striking the East Coastof India and Bangladesh are generated every year in the Andaman Sea. These Islands alsoprone to various geological disaster risks, classified in seismic zone-v, several earth quakeshad occurred in the past but the devastating earth quake that occurred on 26th December2004 caused horizontal and vertical movement of land mass in the Islands generated Tsunamiwaves cost loss of life and properties.In view of the vulnerable profile of these Islands, the Administration established a separateDirectorate of Disaster Management for disaster preparedness, response, mitigation, relief,rehabilitation and to implement the disaster management action plan includes coordination,policy making, operations management, data collection, record keeping, information,education, communication activities, community based disaster preparedness training andestablishment of warning system under the guidance of the Union Territory DisasterManagement Authority and the National Disaster Management Authority.

This qualitative study identifies police interactions with gun violence co-victims as a crucial, overlooked component of police unresponsiveness, particularly in minority communities where perceptions of police illegitimacy and legal estrangement are relatively high. Gun violence co-victims in three cities participated in online surveys, in which they described pervasive disregard by police in the aftermath of their loved ones' shooting victimization. We build on the checklist model that has improved public safety outcomes in other complex, high-intensity professional contexts to propose a checklist for police detectives to follow in the aftermath of gun violence. To build the checklist, we also reviewed the general orders of five police departments to better understand what guidance, if any, is currently given to police personnel regarding how they should interact with gun violence victims.

The authors used the calcaneal pitch angle, talonavicular coverage angle, and lateral talus–first metatarsal angle (Meary angle) to evaluate the flatfoot radiographic parameters and the C1 Cobb angle to evaluate the Cotton osteotomy (CO). Medial column collapse may have a single or multiple sagittal vertices through the talonavicular, naviculocuneiform, or tarsometatarsal joints.2 Although the Cotton osteotomy is useful for correcting an abnormal Meary's angle, adjunctive procedures that were made by the authors could also contribute to correction. This could have biased the sagittal correction of the CO itself. Other radiographic methods have been described and could have been utilized, such as first cuneiform length,1 lateral first metatarsal– medial cuneiform angle (LMCA), sagittal tarso-metatarsal Cobb angle,2 and cuneiform articular angle (CAA), among others.3 These methods represent more accurately the correction power of the Cotton osteotomy and may predict postoperative forefoot behavior. Abousayed et al1 found that the size of the wedge as assessed by the change in first cuneiform length did not correlate with the maintenance of the longitudinal arch at long-term follow-up. In a recent study, Yamaguchi et al5 showed a significant change in the lateral shape of the first metatarsal when plantarflexion is added. The first metatarsal positive round sign changed to negative as the first metatarsal plantarflexed (P = .04, 19 of 20 feet). Wang et al performed a dorsal open wedge osteotomy at the medial cuneiform, filled with a wedged allograft of a femoral head (width 12-15 mm, depth 25 mm, and length 8-10 mm), as a standard procedure. It would have been interesting to address plantarization in the sagittal plane and whether modification of the wedge or the procedure could benefit radiologic and clinical outcomes. Also, it is important to clarify if the changes shown in the study could have been related more to position than to rotation itself.

This case study uses the approach by the Texas government to attempt a state takeover of Houston Independent School District (HISD) to examine the impact of framing on awareness and acceptance of executive action. This work extends recent studies in Georgia and Massachusetts that find stakeholder relationships, the role of Republican governors, and assigning blame as key components of takeover analysis. Using framing analysis, this case study analyzes the impact that framing the takeover action and approach has on these relationships. These findings present an understanding of how narrative construction makes an executive action consistent with administrative and political power to gain acceptability.


An understanding and appreciation of the ocean, Great Lakes and coasts' role in our lives (from commerce to recreation to weather) and our interdependence upon them is a chief goal of the ocean literacy initiative. Today most Americans undervalue the ocean because few know and value the vital functions the ocean performs in service to our society and to each of us individually. One requisite for ocean literacy is the promotion of effective life-long learning of these vital functions and services through sustained communication that captures both our hearts and minds. Story development and data translation address one aspect of lifelong learning, the sustained supply of compelling and accurate science and technology stories about the ocean, coasts, and Great Lakes. Stories that educators and communication professionals can incorporate into all types of learning materials. Here we continue our examination of two models (Government Research Enterprise and an Academic Research Organization) that are case studies in developing and identifying highly effective story development and data translation practices.


Aim: The aim of this study was to evaluate the bond strength of resin cement used in bonding fiber-reinforced composite pulp to canal dentin walls treated with various irrigation agents at different temperatures.
Methods: Seventy-two extracted teeth (single-rooted lower first and second premolars) were used. The teeth were divided into six groups according to the final irrigation solutions applied to the post cavity (n = 12 in each group). The groups were as follows: QMix 2 in 1, 25ºC (group 1); QMix 2 in 1, 40°C (group 2); 2% chlorhexidine digluconate (CHX), 40°C (group 3); 17% ethylenediaminetetraacetic acid (EDTA), 25 °C (group 4); 17% EDTA, 40°C (group 5); and CHX, 25°C (group 6). The irrigation agents were applied for 60 seconds, and root canals were dried. Horizontal sections were obtained 24 hours after fiber post cementation. The bond strength between the fiber post and dentin wall was measured using a push-out tester and recorded. The difference between the two groups was determined by the independent Student's t-test, one-way ANOVA, and Tukey HSD post-hoc test for more than two groups (p<0.05).
Results: The highest apical strength was observed in group 2 (42.240 ± 4.969) and the lowest in group 6 (2.160 ± 0.825). The highest coronal strength was observed in group 5 (55.435 ± 5.396) and the lowest in group 3 (5.139 ± 0.977) (p<0.05). There was a statistically significant difference between the coronal and apical regions in group 1 and group 6 (p<0.05).
Conclusion: The best bonding strength in apical regions was obtained using QMix 2 in 1 (40ºC), and the best bonding strength in coronal regions was achieved using 17% EDTA (40ºC).

This essay re-examines the political and literary engagement of the influential journal Kursbuch with the West German protest movement of the late 1960s. Rather than assessing the journal in terms of its content alone, it points to the ways the layout of the journal helped shape critical discourses of politics and literature. By looking to the journal's margins and the removable posters that were incorporated into its publication platform, the essay sets out to explore how literary form becomes politicized and how that process affects the manner in which we think about reading and about politics.


The possibility of obtaining powdered alloys of iron silicon aluminum was shown. The subject of concentration inhomogeneity of powder materials and methods to control it were considered. The components that create a liquid phase on the stage of sintering and reduce concentration sensitivity of magnetic properties to make powder sendast were selected.


Background Despite the high prevalence of helminth infections among preschool-aged children, control programs in sub-Saharan countries primarily focus on school-aged populations. We assessed the prevalence of helminth infections and determined risk factors for infection among preschool-aged children in the urban setting of Dar es Salaam, Tanzania. Methodology Starting in October 2015, we conducted a 12-month prospective study among tuberculosis (TB)-exposed children under the age of 5 years and unexposed controls from neighboring households. At the time of recruitment, we collected medical histories, assessed development and cognitive functions, and performed medical examinations. We performed full blood cell counts and screened for HIV and malaria. Point-of-care circulating cathodic antigen (POC-CCA), urine filtration, Kato-Katz, FLOTAC, and Baermann tests were employed to detect helminth infections in urine and stool. Helminth infections were stratified for Schistosoma and other helminths to identify risk factors, using logistic regression. Principal findings We included 310 children with a median age of 26 months (inter quartile range 17–42 months) in the study. Among these, 189 were TB-exposed and 121 TB-unexposed. Two thirds of the children were anemic (hemoglobin level <11 g/dl) and the HIV prevalence was 1.3%. Schistosoma spp. was the predominant helminth species (15.8%; 95% confidence interval [CI] 12.1–20.3%). Other helminth infections were less frequent (9.0%, 95% CI 6.3–12.8%). Poor hygiene, use of household water sources, and TB-exposure were not associated with helminth infection. Development and cognitive scores did not significantly differ in helminth-infected and uninfected peers, but hemoglobin levels were significantly lower in helminth-infected children (10.1 g/dl vs. 10.4 g/dl, p = 0.027). Conclusions/significance In Dar es Salaam, a city with more than 4 million inhabitants, the prevalence of Schistosoma spp. infection among preschool-aged children was unexpectedly high. Setting-specific interventions that target preschool-aged children and urban settlements should be considered to reduce the transmission of Schistosoma and other helminth infections and to improve children's health.


We examine the behavior of charged pions in neutron-rich matter using heavy-baryon chiral perturbation theory. This study is motivated by the prospect that pions, or pion-like excitations, may be relevant in neutron-rich matter encountered in core-collapse supernovae and neutron star mergers. We find, as previously expected, that the $\pi^-$ mass increases with density and precludes s-wave condensation at $n_B\lesssim n_{\text{sat}}$, where $n_{\text{sat}} \simeq 0.16 \text{fm}^{-3}$ is the nuclear saturation density, and the mass of the $\pi^+$ mode decreases with density. The uncertainty in these predictions increases rapidly for $n_B \gtrsim n_{\text{sat}} $ because low energy constants associated with the two-pion-two-nucleon operators in chiral perturbation theory are poorly constrained. We find that these uncertainties are especially large in symmetric nuclear matter and should be included in the analysis of pion-nucleus interactions at low energy and pionic atoms. In neutron-rich matter, accounting for the self-energy difference between neutrons and protons related to the nuclear symmetry energy has several effects. It alters the power counting of certain higher-order contributions to the pion self-energy. Previously unimportant but attractive diagrams are enhanced and result in a modest reduction of the pion masses. Furthermore, in the low-wavelength limit, a collective mode with the quantum numbers of the $\pi^+$ appears.

Abstract Twelve cows were fed restricted-roughage rations in a Latin square trial with NaHC0 3 (0.8 lb/day) and MgO (0.4 lb/day) as supplemental treatments. Both supplements prevented the depression in milk fat concentration caused by roughage restriction. Milk fat concentration was studied as a function of plasma fat fractions, plasma acetate, ruminal metabolites, and mammary gland uptake of these metabolites. Sodium bicarbonate affected milk fat through depression of ruminal molar per cent propionate, whereas MgO affected milk fat through increased mammary uptake of plasma acetate and triglycerides. Low-density lipoprotein concentrations were uniquely low in cow plasma compared to other species, but still accounted for a major portion of the arteriovenous difference for plasma lipids across the mammary gland.


Abstract : A 9-year survey on 500,000 Great Lakes naval recruits indicated that only 2 men per 1000 (0.2 percent) had no previous history of dental caries experience at the time of entrance into the Navy. The annual incidence of caries-free men ranged from a low of 1.3 per 1000 in 1967 to a high of 3.1 per 1000 in 1963. Marked variations in the prevalence of caries-free men from different geographic regions of the United States were observed. Correlation analysis indicated that these variations were partly related to the availability of natural fluoride in public water supplies. (Author)


The United Kingdom Conference of Educational Advisers (UKCEA), United Kingdom Association of Programme Directors (UKAPD) and National Association of Primary Care Educators (NAPCE) held a one-day conference on 28 April as a follow-up to a previous conference held one year before. Just like its predecessor, the conference was well attended with a mix of educators from around the UK. The conference was designed around group work with the only formal plenary session being a panel discussion at the close of the day kindly undertaken by Dr Jane Mamelok, Dr Mark Purvis and Professor Arthur Hibble. This allowed maximum discussion and sharing of ideas; the notes from each of the groups are available from the UKCEA administrator Mona Lindsay who did a splendid job in co-ordinating the day. The main messages from the day were that there are still areas requiring work:


The words on the paper in a book tell a story that the author wants people to read. One could consider this the official story in the book. But a book is much more than words on a page. The first two articles in this issue of the Journal delve into the information entwined in a book when it is first made, and reveal how this information can provide histories of not only the book but its makers, authors and the political intrigues in the wider world in which it was used. Bainbridge investigates an intriguing mystery as to why two books, made at the same time and stored in the same conditions since publication, both have two discoloured gatherings in the same place when the rest of the books remain uncoloured. Her use of non-destructive analyses on the books tests the limits of these procedures to produce meaningful results. Her discussions also address whether it is in the best interests of the books and their users to remove the discolorations, taking into account her results and the wider ethical considerations of treating books. In the second article, Skemer and Stanley uncover an eventful history of a Renaissance erasable notebook, from its manufacture in the Low Countries through to its use in Guatemala, discussing the political meanings hidden in its panel-stamped binding. The authors undertook analysis of the pages' composition and experiments into the use of a brass stylus to find out more about the workings of an erasable book. The next article by Van Bos et al. unravels the complexities of wallpaper designs, focussing on the intricate designs of Paul Balin, a late nineteenth century wallpaper manufacturer based in Paris. Research and analysis reveal that his designs were based on a very limited colour palette, the beauty and intricacy being reliant on the mixing of the colours, patterns and textures. Through detailed analysis of a selection of his wallpaper designs, the authors were able to link the retail price for each paper to the processes required to produce it. The original object is not always available for researchers to use. This may be, for example, because it is too delicate for use, or the researcher is not able to visit the object repository in person. Therefore resources have been focussed on providing virtual access to collections. Gallen et al. used the shape-from-shading digitisation method and the website created by the Digital Epigraphy and Archaeology (DEA) project to explore their use on different types of objects found in The National Archives, including seals, metals and lace-like textiles. Although they found that the methods used were not totally successful for all of the object material types tested, their comparisons of scanned images, digital photographs and the 3D images are of great use to others reconstructing virtual models of objects. Standardising The National Archives' approach to the preservation of transparent papers is the subject of the next article. Wilson provides a very useful summary of the history, technology and deterioration mechanisms of transparent paper before discussing her recent work to collate information on the condition of transparent papers in The National Archives' collection from both users and staff. This information will provide an overview of the current situation which can then be used to identify the main areas of concern, and enable a co-ordinated approach to their treatment and long-term preservation. At the Glenbow Museum in Alberta, Canada, Churchill was investigating the best method for displaying one of the founding documents of modern Canada, the Canadian Pacific Railway Charter.

The method of capacitive deionization of water (CDI) is to pump brackish water or seawater though an electrochemical cell, where certain potential difference is kept between carbon electrodes, which are characterized by high specific surface area. This method is sufficiently more attractive from the economical point of view in comparison with other desalination techniques, particularly with reverse osmosis that is widely used in industry. Different modifications of CDI have been developed, for instance, membrane capacitive deionization of water (MCDI) with cation and anion exchange membranes, CDI with ion-selective carbon electrodes, CDI with flow electrodes, CDI with Na-intercalating electrodes, CDI with cation-exchange and anion exchange mixed membrane of mosaic structure, which is used instead of conventional porous separator.


Abstrcat The question that how to solve general heat transfer problems with PDE tool box in MATLAB is introduced. By PDE tool box, you needn't program and can enter the GUI directly to solve practical engineering problem. By analyzing the example of slab with the point heat source's heat transfer, the result shows that it is raopid and simple by using PDE tool box to solve common problem. The engineering importance about the point heat source heat transfer model is also mentioned.

Poly[[2- or 4-[N-t-butyl-N-(triethylsiloxy- or t-butyldimethylsiloxy)amino]-1,4- or 1,2-phenylene]vinylene] was synthesized by polymerizing 4- or 2-bromo-2- or 4-[N-t-butyl-N-(triethylsiloxy- or t-butyldimethylsiloxy)amino]styrene with a palladium catalyst, respectively. They were deprotected and chemically oxidized to yield poly(1,4- or 1,2-phenylenevinylene)s bearing a 2- or 4-substituted built-in nitroxide radical. The polyradicals were chemically stable, and their spin concentration was increased to 0.8 spin/unit. A SQUID measurement which included the corresponding diradicals and triradicals indicated that a partial, but strong, intramolecular ferromagnetic coupling was established through the conjugated backbone, despite a spin defect in the side radical moiety, for the poly(1,2- phenylenevinylene) bearing 4-substituted built-in nitroxide radical.


BackgroundBloodstream infections due to bacterial pathogens are a major cause of morbidity and mortality among pediatric patients. Emergence of drug resistance in high classes to antibiotics among the bacterial pathogens is another issue of public health concern. Therefore, this study was conducted to determine multi-drug resistant, extended spectrum β-lactamase and carbapenemase producing bacterial isolates among suspected bloodsteam infection patients in children under five years of age at Tikur Anbessa Specialized Hospital, Addis Ababa, Ethiopia.MethodsA cross-sectional study was conducted from September 2017 to June 2018 among pediatric patients with febrile illness under five years of age at Tikur Anbessa Specialized Hospital. Three hundred and forty blood samples were collected and processed following standard microbiological techniques and blood culture was performed using a BacT/Alert instrument in combination with conventional methods for identification. Antimicrobial susceptibility testing of the isolates was performed using the Kirby-Bauer disc diffusion method to determine the minimum inhibitory concentration (MIC).ResultA total of 137 (40.2%) bacterial pathogens were isolated from 340 pediatric patients suspected of bloodstream infection with febrile illness. Of these isolates, 54% were Gram negative bacteria. Among gram negative isolates 43 (31.4%) were identified as Klebsiella pneumoniae and 8.7% Acinetobacter species were the most frequently isolated pathogens. Klebsiella pneumoniae isolates were 88.4 % (38/43) MDR, 32.5% (14/43) ESBL, and 37.2 %( 16/43) CRE .ConclusionIn this study, highly resistant Klebsiella pneumoniae are common pathogen associated with BSI. Extended spectrum beta-lactamase (ESBL) producing strains were common in Klebsiella species and Escherichia coli isolates. Since most of isolates exhibit multidrug resistance, in vitro antimicrobial susceptibility testing is mandatory. A strengthened antimicrobial surveillance system and antimicrobial stewardship programs are necessary for better selection of antibiotics in addition to improved infection prevention practices in hospital settings.


This paper aims at exploring motivations driving virtual community and virtual world members' participation—virtual participation. The expression theory and interpersonal relationship perspective is introduced as a framework through which to explore the participation of virtual world members, using a interpersonal relationship model—the Fundamental Interpersonal Relationship Orientation (FIRO) model (Schutz, 1966, Schutz, 1958). Specifically, the paper attempts to explain that members desiring to expression them and fulfill their interpersonal relationship needs in both virtual communities and virtual worlds. Specifically, two main types of virtual involvement behavior, Behavior to Obtain Information (BOI) and Behavior to Give Information (BGI) are investigated. The data were collected from two virtual communities—Microsoft Chinese Community and the Xilu Communityand a virtual world—Cyworld and analyzed with ANOVA for the FIRO model. The results show that the interpersonal relationship model can explain virtual participation. At the same time, members are more expressive in virtual worlds than in virtual communities.


For social creatures like us, enjoying lasting, stable, and secure relationships is neither a luxury nor a triviality: it is quintessential to leading a minimally good life. Our sociability is both intrinsically valuable and indispensable to the fulfilment of other important interests. This introduction briefly describes the nature of our core social needs and the social human rights to which they give rise. It maintains that human rights should be minimalistic, but such minimalism must prioritize social rights such as the human right against social deprivation. The duties that such rights generate apply to both governments and individuals, making the ethics of sociability a matter of both social justice and personal morality.


A sensitive method is needed to analyze soil-water extracts that contain P at submicromolar concentrations. The proposed spectrophotometric method, based on the ionic association of malachite green with phosphomolybdate under acidic conditions, was evaluated on soil extracts. The molar absorptivity was 64 641 ± 743 L mol cm. Absorbance of the reagent blank was 0.069 ± 0.004. With 1cm path length cells and limiting absorbance of 0.004, the detection limit calculated from the Beer-Lambert equation was 6.7 X 10 M orthophosphate P. Recovery of added P in saturated paste extracts averaged 91% with a range of 87 to 94% and averaged 101% with a range of 93 to 109% for 1:1 soil/water extract. The method was successfully applied to saturated paste extracts from soils of varied organic matter content and pH. The proposed malachite green method allows for P determination in restricted volume samples and at concentrations too low for the standard Murphy-Riley method.


Modelling collaborative processes is a complex task because it may involve many people with different backgrounds, each having their own focuses and interests. To get a perfect process description, a mechanism must be provided to support the cooperation among these people. It is in this sense that we declare that process modelling by itself is a collaborative process, which is neglected in existing modelling tools. This paper summarises the characters of this special process, then presents the policies needed to support the efficient cooperative modelling of processes so that perfect process descriptions can be produced. These policies are implemented in CovaModeler, which is a multi-user tool for Cova-based process collaborative modelling.

The first antivenom was prepared by Calmette in 1894. More than a century later, it is still the only specific treatment for envenoming. The methods currently used by almost all antivenom producers worldwide to isolate and concentrate antivenom antibodies and their enzymatically derived fragments are improvements of those originally developed by Pope in 1938. Several new alternatives have been proposed to produce F(ab')2 or Fab antivenoms to improve their purity, neutralizing potency, and safety and to overcome the problems encountered in the production protocols based on ammonium sulfate precipitation of equine immunoglobulin. These include complete or partial modifications in the antivenom production regarding animal producers (ovine, laying hens...), immunization protocols, crude serum preparation and/or purification procedures concerning antibody extraction (PEG, caprylic acid, ion-exchange chromatography or immunoaffinity chromatography), and cleavage conditions (pepsin, papain...). In Tunisia, antivenom has been produced since the 1950's. Constant improvements and standardization of all the steps involved in antivenom production, purification, and quality control have resulted in a pure, safe, and efficient F(ab')2 product with no side effects when used intravenously, and with a high seroneutralization yield, as a result of the high toxin specific F(ab')2 concentration. The real impact of the new or modified procedures is a substantial increase in the cost of an antivenom dose. The quality is similar to that of the old procedure when its production was accurately standardized, optimized, correctly conducted and controlled. In addition, severe side effects have been reported after application of either equine F(ab')2 or ovine Fab antivenoms purified by the new methods (i.e. ion-exchange chromatography and immunoaffinity chromatography). Consequently, the introduction of these methods in developing countries still needs justification.


The article considers the development of Shakespeare's ideas in Shelley's drama. The problem of the divine justice was perceived by Shelley through the prism of Shakespearean plays. The motives of protest against cruel tyrant and of retribution for crimes give a common ground for the plays "Richard III", "Prometheus Unbound" and "The Cenci".


Thirty-four cases with supracondylar fractures of the humerus in children were treated during five years period from 1982 to 1987.Out of them twenty-three subjects were medically examined. Thirteen cases were treated surgically and ten by percutaneous pinning. These were compared to each other. We measured three factors, that is, coronal tilting (varus), anterior angulation (hyperextension) and horizontal rotation (internal rotation), which are thought to be connected with cubitus varus. We calculated coefficient of correlation between cubitus varus and three factors. There was a significant correlation between cubitus varus and coronal tilting (r=0.93, p<0.01), and a relatively high correlation between cubitus varus and anterior angulation (r=0.57, p<0.01). But the correlation between cubitus varus and horizontal rotation was not so significant (r=0.39, p<0.10).


Mathematical models of changes in the rate of water filtration during the process of roller squeezing of leather were determined. It was revealed that the graphs of the mathematical models obtained correspond to experimental diagrams obtained by squeezing various wet materials. From the point of view of water motion, the roll contact zone (a squeezing area) is divided into four sections (phases). It was revealed that the filtration rate in the first two sections of the roll contact zone increases from an initial negative value to a maximum positive value, and in the last two sections of the roll contact zone, it decreases from a maximum value to a certain negative value.


This report presents the findings of a follow-up study concerning the demand for Oral Rehydration Solution (ORS) at pharmacies in Egypt and the knowledge attitude and practices of pharmacists. Pharmacists represent the sole source of commercially distributed ORS in Egypt. This follow-up study had 2 objectives: reassessing the knowledge attitude and practices of pharmacists toward ORS; and examining any changes in the level of demand for ORS at the pharmacy level. This study conducted in February 1985 interviewed 300 pharmacists in 11 governorates. All but 10% of the pharmacists surveyed in the follow-up study took part in the pilot study conducted in August 1984. In the follow-up study 72.3% of the pharmacists reported recommending ORS to mothers of children with diarrhea compared to 64.3% in August. Additionally the number of pharmacists prescribing antidiarrheal drugs is declining (yet 90.7% of pharmacists still believe that ORS alone is not enough to give a child with diarrhea). 98.7% of the pharmacists now sell ORS compared to 96.7% in August 1984. Compared to 47.3% in the previous study 96% of pharmacists reported no recent difficulties in obtaining ORS. Pharmaceutical representatives remain the leading source of information for the pharmacists. The findings of the follow-up study indicate that the pharmacists attitude toward ORS is improving judging by the increasing percentage who advise ORS. But although the number of pharmacists advising antidiarrheal drugs is declining the figure is still not encouraging. The report recommends additional efforts at reducing the prescription of antidiarrheal drugs and further ORS training for doctors and pharmacists.


The soft additive segmentation model attempts to solve the problem related to the segmentation of overlapping objects with additive intensity value. An issue in optimizing the soft additive segmentation functional is that a high-order nonlinear partial differential equation needs to be solved, which, for most standard algorithms, involves high computational cost. In this paper, we propose a fast and efficient numerical algorithm to optimize the soft additive segmentation model. We reformulate the original minimization problem into a sequence of simpler minimization problems that can be solved efficiently by using the augmented Lagrangian method. Numerical tests on real and synthetic cases are presented to demonstrate the efficiency of our algorithm.


It has been investigated the adsorbtion of chrom metal in chemistry laboratory liquid waste using tanah napa as an adsorbent. Waste containing chrom metal was pass through a coloum that filled with tanah napa adsorbent. It is studied the use of nitrit acid (HNO 3 ) for regeneration purpose and recovery of chrom metal at various concentration. The result showed that HNO 3 at concentration 0.4M was the best for regeneration of Chrom(III) is 78.03% and concentration 0.3M for regeneration of Chrom(VI) is 53.02%. The optimum condition of this method were applied to preconcentration of Chrom in chemistry laboratory liquid waste with HNO 3 0.3M. The result show that Chrom found in chemistry laboratory liquid waste which is initially 0.9123 ppm can be preconcentration to 1.7760 ppm with 5x10mL preconcentration.


ABSTRACT Food-borne pathogens sicken 76 million people and result in 325,000 hospitalizations and 5,000 deaths each year in this country. Long-term studies have overwhelmingly demonstrated the safety and effectiveness of food irradiation for preventing such illness and earned support from numerous health organizations. Unfortunately, these benefits cannot be realized if consumers do not purchase irradiated meats. As a result of recent government approvals, irradiated chicken and ground beef will be increasingly available to U.S. consumers during 2000. This paper describes the irradiation process, its benefits in preventing food-borne illness, and current educational efforts in this area by the Florida Department of Health. Public health professionals and medical practitioners can make a valuable contribution to reducing food-borne illness by becoming knowledgeable on the irradiation process and by advocating for the consumption of irradiated meats.


Abstract : The U.S. Army Tank Automotive Research, Development, and Engineering Center (TARDEC) and the Defense Advanced Project Agency (DARPA) are partnering to develop fundamentally new water technologies to reduce the logistics footprint and enable the development of a decentralized water support concept. The individual soldier requires 1.5 to 3.5 gallons per day to prevent dehydration. When personal hygiene, meal rehydration, and emergency medical treatment are included the daily planning factor becomes 4.1 gal per soldier per day. Current state-of-the-art water purification equipment can purify any source of water, but this potable water must then be transported from the source to the point of use on the battlefield. Without advances in water sustainment technology, water distribution is projected to account for 30 to 40% of the Objective Force daily sustainment requirement. TARDEC and DARPA are developing a range of revolutionary technologies for water recovery and generation. These technologies will produce water anywhere on the battlefield, thereby enabling the development of distributed water production systems to augment the soldier's water supply and significantly reducing the frequency and quantity of resupply. The technology will provide military units with a radically more mobile and flexible water production capability. The technology will enable future sustainment concepts allowing units to operate without external resupply for 3 to 7 days.


Interference of anti‐phospholipid antibodies with the protein C pathway has been suggested to play a role in the development of thrombosis in the anti‐phospholipid syndrome. We studied the effect of IgG preparations containing anti‐prothrombin antibodies of 17 lupus anticoagulant‐positive patients and 12 controls on the inactivation of factor Va (FVa) by activated protein C (APC) in a system with purified coagulation factors. Test IgG was incubated with human prothrombin, phospholipid vesicles and CaCl2. Protein S, FVa and APC were added and the APC‐dependent loss of FVa activity was monitored over time. The residual amount of FVa remaining after 10 min was 14 ± 4% (mean ± SD) when 1·5 mg/ml normal IgG was present and ranged between 17% and 82% with 1·5 mg/ml patient IgG. Twelve patients IgG gave values of residual FVa >22% (i.e. 2 SD above the mean of controls), indicating that APC‐mediated inactivation of FVa was significantly inhibited. The inhibition was strictly dependent on the presence of prothrombin, proportional to the concentration of IgG and strongly diminished at a 20‐fold higher phospholipid concentration. Most, although not all, IgG containing anti‐prothrombin antibodies inhibit the APC‐catalysed FVa inactivation, which may contribute to the increased risk of thrombosis in patients with the anti‐phospholipid syndrome.


: Protected areas pose a major interest in the current context in which natural habitats are very fragmented as a result of economic development. The ROSCI0076 Dealul Mare- Hîrlău site represents the largest protected area from Moldova's Plateau where forest habitats occupy a majority surface. A total number of 10 Natura 2000 forest habitats were identified on the site's surface. Among them, the majority are 91Y0 - Dacian oak hornbeam forests and 9130 - Asperulo-Fagetum beech forests. These are comprised of 79% natural forests, while planted forests represent 19%. The main age ranges between 40 and 80 years, with compact areas with young forests, as well as with forests older than 100 years. Forest habitats are stable from an ecological point of view, ensuring optimum conditions for the development and colonization of species presented on the site's map.


During my decade of neurosurgical experience in Northern Ireland, I became fairly used to managing patients involved in sectarian skirmishes. Most patients were young lads with a Northern Irish accent, usually victims of violent incidents like stone throwing, assaults, or even punishment beatings. The commonest type of injuries were long bone fractures, "knee-cappings," and depressed fractures of the skull. Generally, the patients were conscious when admitted on to the neurosurgical wards. Contrary to what one would have expected, they showed hardly any of the religious hatred that would be a natural reaction, in such circumstances, anywhere else in the world. They were, surprisingly, very friendly, cooperative with the staff, and had …


Establishing a basis for certification of autonomous systems using trust and trustworthiness is the focus of Autonomy Teaming and TRAjectories for Complex Trusted Operational Reliability (ATTRACTOR). The Human-Machine Interface (HMI) team is working to capture and utilize the multitude of ways in which humans are already comfortable communicating mission goals and translate that into an intuitive mission planning interface. Several input/output modalities (speech/audio, typing/text, touch, and gesture) are being considered and investigated in the context human-machine teaming for the ATTRACTOR design reference mission (DRM) of Search and Rescue or (more generally) intelligence, surveillance

We experienced an operated a case of pedunculated lipoma of the duodenum. A 77-year-old woman underwent upper gastrointestinal series for anemia at another hospital and was found having a submucosal tumor of the duodenum. The patient was admitted to the hospital. CT scan showed a round lesion with fat density at the duodenum. T1 weighted and T2 weighted MRI showed a high intensity tumor 4×3×2cm in size at the 2nd portion of the duodenum, which seemed serial to the duodenaol wall. The tumor was shown a low intensity mass on fat controlled T1 weighted MRI. Under a diagnosis of peduculated lipoma at the 2nd portion of the in size, and histologically, a duodenal submucosal benign lipoma. According to the previous reports in Japan, there were 84 cases of duodenal lipoma, including our case. The characteristics, symptoms and treatment methods were discussed together with review of the literature.


The new oral direct thrombin inhibitor, dabigatran, is proving to be problematic in acutely injured patients, since it may promote bleeding and its effect cannot be easily reversed.


Ideological and political education in Colleges and universities for students cheating on exams in the current problems are using high pressure policy. But the effectiveness of this education strategy in the practice is not ideal. This is status of current college student exam flood analysis. Analysis on the problems existed for a long time. At the same time, put forward a series of effective prevention and education strategy. After the analysis by the ideological and political education point of view, the education method and the corresponding theory were put forward. The practice proved the effectiveness of these educational theories and Strategies of these theories have important reference meaning for cheating problems to deal with the current college students in the exam.


The transmission of linearly polarized plane wave through cascaded metal films perforated with periodic hole arrays is investigated by using the three-dimensional finite-difference time-domain method. The results show that the transmission spectra can be controlled by changing the longitudinal interval G and/or the lateral displacements Lx and Ly, which are parallel and perpendicular to the polarization direction of the incident light, respectively. The variation in longitudinal interval G results in a redshift or blueshift of the transmission peak due to the coupling of the localized surface plasmon (LSP) modes on two metal layers. The lateral displacement Lx leads to the splitting of the transmission peak, originating from the variation in the coupling manner of LSP modes, while the lateral displacement Ly suppresses the transmission peak.


A distinction is made between implicit and explicit group overlap in sociological data, and literature is briefly reviewed in terms of this distinction. The conclusion is drawn that for implicit overlap, the method of data analysis should use continuous input, while yielding output in a discrete form of (possibly overlapping) subsets. Such a method of clustering (ADCLUS) is presented briefly and is applied to the communication structure of a biomedical area of specialization.


Background: The use of cardiopulmonary bypass (CPB) triggers a systemic inflammatory response (IR), but it is not known if a similar response occurs in an immuno-suppressed patient with autoimmune disease. Methods and results: Observational study in a 56-year-old man receiving immunosuppressive therapy for Wegener's granulomatosis (WG) who underwent aortic valve replacement on CPB. The following markers for IR were studied in the perioperative period: C3a, C5a, neutrophil elastase (NE), interleukin eight (IL-8), white cell count (WCC) and C-reactive protein (CRP). Results were compared with published literature on the IR in patients undergoing coronary revascularisation with and without the use of CPB. All inflammatory markers increased in the perioperative period. The intensity of IR was markedly reduced compared to published literature for patients undergoing coronary revascularisation on CPB and the temporal patients and extend resembled that for off-pump. Conclusion: In a patient with WG on immunosuppressive therapy the CPB-related IR is reduced.


A unified approach for direct simulations of fluid flow, heat transfer, and phase changes is discussed. The method is based on writing one set of conservation equation for all phases involved, allowing arbitrary changes in material properties and adding singular terms at phase boundary to ensure that the correct boundary conditions are incorporated. This approach allows the conservation equations to ge solved on a fixed grid in a very efficient way. By explicit tracking of the phase boundary by a lower dimensional moving grid, the method is capable of producing accurate solutions for complex phase boundaries. Examples of simulations of the solidification of pure materials, binary alloys, and drops impinging on a solid surface are shown.


he book burners and the thought censors are back with us again as they intimidate legislators, disrupt board meetings, hassle teachers, and threaten to purge school books with fire and scissors. No book is safe, Mother Goose and the dictionary included. Donald Duck has been charged with immorality because of his untrousered bottom, and Dickens has been called antiSemitic because of his portrayal of Fagin (never mind that the Jew, Riah, in Our Mutual Friend, is a much nicer person). The ability to arouse controversy does not, in itself, identify the superior artist, but it is the very nature of any craft that creative individuals are controversial. One who has greater insight than others-the one who can see meanings which link seemingly unrelated ideas and is willing to follow the truth wherever it leads-will often be a majority of one. Pasteur, who propounded his germ theory of disease; Luther, who tied salvation to faith alone; and Laura Ingals Wilder, who luxuriated in her prairie truths-these and countless other have been celebrated because they stumbled upon something hidden from the rest of us. What they did was to recognize and systematize ideas and truths waiting for any observer to find. Yet these people were laughed at when they first revealed their thoughts. Much that horrifies the would-be censors now may be regarded in the future as the finest of art.


Background. Recent reports have indicated that immigrants have an elevated risk of schizophrenia as well as an increasing tendency for social exclusion. The aim of this study was to compare rates of schizophrenia and other psychoses in immigrants and their children of different ethnic groups with the majority population in Sweden in relation to social adversity. Method. The study population consists of a national cohort of 1·47 million adults (born 1929–1965) and 1·16 million children and youth (born 1968–1979) in family households from the national census of 1985. Multivariate Cox regression analyses was used to study hospital discharge data during 1991–2000 in relation to socio-economic household indicators from 1985 and 1990 (single adult household, adults having received social welfare, parental unemployment, urban residency, housing and socio-economic status). Results. First as well as second generation immigrants had higher age and sex adjusted risk ratios for schizophrenia as well as for other psychoses (RRs 1·4–3·1 and 1·0–2·0 respectively) compared with the Swedish majority population. These risk ratios decreased considerably after adjusting for socio-economic indicators, for all groups, but particularly for the non-European immigrants. However, an elevated risk still remained in the Finnish and Eastern and Southern European study groups. Conclusions. A higher risk of schizophrenia and psychoses was found in two generations of immigrants of diverse ethnicity. The results indicate that social adversity contributes to the higher risk.


The emitted noise and vibration induced by the unsteady flow of the centrifugal pump are always focused during its running, which is also associated with the high amplitude pressure pulsations. How to reduce pressure pulsations remains a crucial problem for the researcher considering low noise design of the centrifugal pump. In the current research, a special staggered impeller is proposed to reduce intense pressure pulsations of a centrifugal pump with ns = 69 based on alleviating rotor‐stator interaction. The numerical simulation method is conducted to illustrate the influence of staggered impeller on the pump performance and pressure pulsations, and three typical flow rates (0.8ФN–1.2ФN) are simulated. Results show that the staggered impeller will lead to the pump head increasing, and at the design working condition, the increment reaches about 3% compared with the original impeller. Meanwhile, the pump efficiency is little affected by the staggered impeller, which is almost identical with the original impeller. From comparison of pressure spectra at 20 monitoring points around the impeller outlet, it is validated that the staggered impeller contributes significantly to decreasing pressure pulsations at the concerned working conditions. At the blade passing frequency, the averaged reduction of 20 points reaches 89% by using the staggered impeller at 1.0ФN. The reduction reaches to 90%, 80% at 0.8ФN, 1.2ФN, respectively. Caused by the rib within the staggered impeller, the internal flow field in the blade channel will be affected. Finally, it is concluded that the proposed staggered impeller surely has a significant effect on alleviating intense pressure pulsation of the model pump and does not obviously alter the global performance of the pump, which is very promising during the low noise pump design considering its feasibility for manufacturing.


The symbiosis between arbuscular mycorrhizal (AM) fungi, subphylum Glomeromycotina, and terrestrial plants is one of the most widespread and arguably most successful plant symbioses on Earth. This ancient relationship, going back 475 MY (Remy et al., 1994; Redecker & Raab, 2006; Field et al., 2015; Rich et al., 2021) is beneficial for the fungi and normally benefits their plant partners. Through colonisation of plant roots, the fungi provide their host plants with access to soil elements including phosphorus (P) and nitrogen (N) while the fungi are provided with carbon (Hodge et al., 2001; Smith & Read, 2008; Keymer & Gutjahr, 2018). The contribution of AM fungi to ecosystems goes beyond nutrient delivery to plants.


This study investigates the circulation driven by a severe bora wind event in the Gulf of Trieste during the stratification season. A preliminary numerical analysis of the wind driven transport in the surface boundary layer is carried out for an idealized, laterally unbounded, shallow domain. Then, the simulations are focused on the Gulf of Trieste, using a realistic bathymetry and assuming stably stratified initial conditions. First, the model is driven by constant wind forcing, then qualitative and quantitative estimations of the dynamics of the basin are made reproducing the strong Bora event of the 25 June 2002. Numerical results show good agreement with in situ measurements and remotely sensed images. The relevance of coastal upwelling and its persistence are also assessed. The results prove that mixing and coastal upwelling (both wind-driven) govern the circulation of the basin. When bora starts blowing, buoyant surface water is moved by EKMAN transport offshore inducing a bottom onshore current. Simultaneously, wind driven stirring breaks the initial stable stratification. The surface offshore current generates a sea surface level setup on the northern boundary. When bora decreases, this surface tilt is no longer sustained, and a reversal of the circulation is observed in the upper layer. The sensitivity to the wind forcing is also discussed. All of these issues are crucial to environmental problems such as pollutant dispersion or anoxia phenomena in the bottom layers of the Gulf.

Objective: To introduce a case report of a patient developing guttate psoriasis following a COVID-19 infection. The case report reviews the patient presentation, diagnosis, treatment plan, and reviews current literature. The overall goal of this case report is to inform medical providers that COVID-19 may cause guttate psoriasis. This is important because guttate psoriasis can be induced by streptococcus bacterial infections and less commonly viral infections. A comprehensive literature search using the key words "guttate psoriasis and COVID-19 infection," "guttate psoriasis post viral infection," and "guttate psoriasis and COVID-19 vaccination," was conducted using databases including Google Scholar, PubMed, and ScienceDirect.


A frictional geostrophic model is used to examine how the stability of the thermohaline circulation is affected by idealized topographic variations and the presence or absence of wind stress. If the flow exhibits collapses, the authors consider how topography and wind stress affect the ensuing oscillations. Large-scale slope up toward the north or the west can significantly destabilize the circulation by modifying the barotropic flow and reducing the depth of convection. Wind stress stabilizes the circulation by deepening the thermocline in the subtropical gyre. Wind driving can also radically reduce the period of oscillations by destabilizing the northern halocline in the collapsed phase. The overall period of the oscillation is usually governed by the time taken for diffusive warming to destabilize the deep ocean.


Abstract Tungsten and nitrogen co-doped carbon dots (W, N-CDs) with a high quantum yield of 51.08% were synthesized by a facile hydrothermal process. Doping of tungsten effectively enhanced luminescent properties of the carbon dots, and the quantum yield was increased by 10.3%. The surface composition and morphology of the synthesized W, N-CDs were characterized. W, N-CDs were employed as nanoprobes to develop a sensor for the selective and sensitive determination of Hg2+ and captopril. Under the optimal conditions, the linear response range for Hg2+ and captopril were 0.125 to 9.0 μM and 0.5 to 10 μM with detection limits of 40 nM and 300 nM, respectively. The developed sensor was successfully applied for the determination of Hg2+ in water and captopril in urine with recoveries from 95.50 to 105.50% and 96.33 to 105.13%, which demonstrates suitable accuracy and reliability. The fluorescence mechanisms of W, N-CDs toward Hg2+ and captopril were also evaluated.


The traditional methods for facilitating complex thinking in the Information Technology (IT) learning area, fail to concentrate on an appropriate integration of various modes of learning within the stages of the technological process. The nature of facilitating complex thinking during Information System Design (ISD) is not clearly described in literature. The aim of this paper is to explore the facilitation of complex thinking through the Instructional Web Design Model (IWDM). This paper provides a description of the IWDM, highlighting its criteria, assumptions, the purpose, the structure and planning for the implementation. The IWDM is based on the implementation of the Instructional Web Design Programme (IWDP) and corresponding findings in terms of learners' and the teacher's experience of the IWDP. The IWDM offers learners a constructivist vision of multimethod learning in the ISD environment, enlarging and strengthening the insight into the design process and a climate for enhancing intellectual processes and skills. This research was embedded in a qualitative, action-research approach where interviewing, focus group interviewing, observation and document sources were used to gather data. Although the IWDM is based on a case study (located in the computer laboratory at RAU) reflecting conditions in the project-based classroom, the model can be applied to similar project-based classrooms specifically within the ISD context.

In PNAS, Sylvester et al. (1) assess the functional connectivity of the human amygdala with well-established brain networks using functional magnetic resonance imaging (fMRI). This focus on the amygdala was chosen because this region has been often implicated in psychiatric conditions. Better understanding of its connectivity and functions may therefore be helpful as the field moves in the direction of individualized treatments for psychiatric problems.

The amygdala was first identified in the early 19th century when the German anatomist, Karl Friedrich Burdach, came across an almond-shaped structure in the human brain and named it using a word derived from the Greek word for almond (2). A century later, the term amygdala had come to designate a larger area in which the almond-shaped region was only a component. Today, the amygdala is recognized to have more than 12 anatomical areas, or nuclei, each with several subdivisions and unique patterns of connectivity in the brain (3, 4). These are sometimes grouped into three partitions: basolateral, centromedial, and cortical (5).

Despite the singular designation, the amygdala, like all brain areas, is a twin structure, with one amygdala in each cerebral hemisphere. From a comparative perspective, the amygdala is a common feature of the vertebrate brain, although it is considerably more developed in mammals than in other vertebrates (6).

When discussing brain areas, it is important to recognize that the criteria used in their initial characterization, often in the 19th century, were relatively crude. Consequently, with modern methods the boundaries of areas often shift, and sometimes what seemed like two areas may turn out to be a continuous one, leading to debates about what to call the area. Some, for example, question the existence of the amygdala as an independent region, arguing it is a subregion of the striatum (2). …

Complements to a theorem of Bourbaki on the disintegration of measures on separated topological spaces. If X and T are separated topological spaces, v is a measure on X, andp is a mapping of X into T, then, under suitable hypotheses, there exist a measure I = p(p) on T and a family (Xt)tI T of measures on X indexed by T, such that (a) for every t E T, XA is carried byp -I({t}), and (b) v = f At dtt(t) in an appropriate sense; moreover, (c) IIXAII = 1 for locally It-almost every t in T, and (d) the family (X)I T is determined by properties (a) and (b) up to a locally I-negligible set [2, ?2, No. 7, Proposition 13]. The purpose of this note is to repair a gap in the proofs of (c) and (d) given in [2]. {To pinpoint the problem: in the proof of (c) on p. 42 of [2], the application of (12) is unjustified since the function f4A need not be universally measurable.) For greater clarity, we shall operate under somewhat weaker hypotheses than [2] (to which we refer for notations and terminology). For the rest of the paper, X and T denote separated topological spaces, v is a measure on X (all measures under discussion are positive), IL is a measure on T, and t X is a mapping of T into the set of measures on X. If f E IF+ (X) (that is, f is a positive numerical function on X), we define positive numerical functions hf and hf* on T by the formulas hf(t) = hf7(t) = X,*(f) (thus 0 AC(hf*) > !(hf). PROOF. Formally the same as in [1, ?3, No. 2, Proposition 3]. [1 LEMMA 2. If f E + (X) is v-negligible, then f is X,-negligible for locally I-almost every t in T. Received by the editors July 15, 1977.

MaskedFusion is a framework to estimate 6D pose of objects using RGB-D data, with an architecture that leverages multiple stages in a pipeline to achieve accurate 6D poses. 6D pose estimation is an open challenge due to complex world objects and many possible problems when capturing data from the real world, e.g., occlusions, truncations, and noise in the data. Achieving accurate 6D poses will improve results in other open problems like robot grasping or positioning objects in augmented reality. MaskedFusion improves upon DenseFusion where the key differences are in pre-processing data before it enters the Neural Network (NN), eliminating non-relevant data, and adding additional features extracted from the mask of the objects to the NN to improve its estimation. It achieved $5.9mm$ average error on the widely used LineMOD dataset, which is an improvement, of more than 20\%, compared to the state-of-the-art method, DenseFusion.

The mechanisms involved in N2O production, consumption and air-sea interactions in fluvial systems are modulated and affected by several factors, including hydrological, chemical and anthropogenic impacts. In recent decades, the basin of the Biobío River (central Chile) has been impacted by an enhanced precipitation deficit and anthropogenic pressure, so the aim of the present work is to understand the spatial and seasonal dynamics of N2O during a megadrought that has been affecting the river since 2010. We also aim to determine the annual contribution of N2O to the atmosphere and the possible response of the Biobío River to projected climatic changes. Seasonal sampling of the water physical-chemical properties was carried out at 15 stations along 280 km of the river and its five tributaries; the stations were distributed between the pristine headwaters (700 m asl) and the outlet of the river at the Pacific Ocean. The longitudinal distribution of oxygen, nutrients, and nitrous oxide evidenced agricultural, urban and industrial impacts on the river water. Headwater areas presented the highest oxygen concentration and the lowest nutrient and N2O concentrations, all of which fluctuated with the variability in water discharge with the different seasons. In the middle river section, where agricultural, industrial and urban activities A cc ep te d A rti cl e
