Acute Oral Toxicity and Histopathological Study of Combination of Endosulfan and Cypermethrin in Wistar Rats

Background: Endosulfan, a neurotoxic organochlorine insecticide and cypermethrin, a synthetic pyrethroid insecticide used to control pests in domestic, industrial, and agricultural situations. Materials and Methods: The present study was carried out to investigate the acute oral toxicity, behavioral and histopathological changes of combination of endosulfan and cypermethrin in albino rats. According to Miller and Tainter analysis method, at 48 h, LD50 value of combination of endosulfan and cypermethrin (ratio 1:1) in rats was found to be 691.83 mg/kg bw by oral gavage. Results: When combination of both these pesticides was administered orally at concentration of 103.72 mg/kg bw, 172.95 mg/kg bw and 207.50 mg/kg bw, respectively, as a single dose, no significant changes in behavior of rats was observed, neither in dosed nor in control group of rats. Combination of endosulfan- and cypermethrin-treated rats showed mild histopathological changes in liver and kidney in group IV (207.50 mg/kg BW) as compared to the control. However, no significant changes were observed in brain and small intestine at either dose of combination of endosulfan and cypermethrin with respect to control. Conclusion: Thus, the present study, first of its kind in India, demonstrated the oral toxicity, behavioral, and histo-architectual alterations after induction of combination of endosulfan and cypermethrin at acute doses in Wistar rats.
Analysis of Determinants of M-Commerce Adoption by Online Consumers

M-Commerce is the making of payments for products and services through the use of mobile devices. The proliferation of mobile devices has resulted to into substantial growth of M-commerce. This is as a result of anytime anywhere connectivity, low cost of business, increased new sales avenues and customer loyalty. But even with the high penetration rate of Mobile phones, a relatively low adoption rate of M-Commerce has been observed in the developing countries. This study provides the theoretical underpinning for various interventions to promote M-Commerce Adoption. The study uses the literature review to identify the factors which influence the adoption of M-Commerce by consumers. The results from this study will be useful to m-commerce companies in formulating appropriate marketing strategies, as well as developing appropriate applications that address the needs and resources of various stakeholders. The outcome of this study will guide companies that offer MCommerce related products in the selection of digital products and in pursuance of future commercial opportunities. The finding of this study recommends that the government should set up legislation that would ensure customer security in order to enhance trust and hence enhance M-Commerce adoption.
AFM images of undoped amorphous carbon thin films deposited by bias-assisted thermal-CVD

The undoped of amorphous carbon thin films were deposited by bias assisted thermal-CVD system at various deposition temperatures in the range 300°C to 500°C with fixed negative bias of -40V for 3 h deposition. The thin films were characterized by Atomic Force Microscopy (AFM), surface profiler, and I-V measurement. The results showed that the distributions of undoped thin films were more density when the temperature is increased at 400°C and 500°C for 3 h deposition times. The resistivity of undoped a-C thin film at 300°C, 350°C, 400°C and 500°C is 9.57×10<sup>6</sup> Ω/cm, 9.44×10<sup>6</sup> Ω/cm, 9.81×10<sup>5</sup> Ω/cm and 337738.124 Ω/cm respectively. The conductivity of thin films was increased by the increasing of temperature. The AFM images showed that, density and uniformity had correlated with the resistivity and conductivity of undoped amorphous carbon thin films for various temperatures.
Aggression Between Heterosexual Dating Partners

The authors used structural equation analyses of data obtained from a survey of 345 college undergraduates (232 women, 113 men) to test a predictive model of dating aggression based on the background-situational model proposed by Riggs and O'Leary (1989). Results offer initial support for the background-situational model. Among men and women, dating aggression was directly related to the individual's attitudes about dating aggression, history of aggressive behavior, and conflict within the relationship. However, the predicted association between family of origin violence and attitudes toward aggression and general aggressive behavior was found only among women. Among men, the predictors explained more than 60% of the variance in the latent variable of relationship aggression; among women, 32% of the variance was explained. Discussion focuses on the utility of the background-situational model for understanding etiological factors of dating aggression and indentifying targets for interventions aimed at reducing the problem.

Rethinking Social Work's Interpretation of ‘Environmental Justice’: From Local to Global

This article challenges social workers to expand their understanding of the ‘person-in-environment’ perspective and become more active in addressing current environmental crises. Although social work scholars have begun to explore the relationship between social work and the natural and built environment and professional organizations mandate the integration of this content into practice and education, these goals remain unrealized, particularly in the USA. To address these issues more effectively, social work educators will need to distinguish between understanding persons in their environment and environmentalism, and between environmentalism and environmental justice. This article analyzes the emergence of the environmental justice movement in the USA and other nations and its relationship to environmental racism. It presents a case study of a local environmental justice effort to demonstrate how social workers can use their knowledge and skills to make important contributions to environmental justice and sustainability. It also discusses the potential of ‘green social work’ and transformative learning theory as tools to help social work educators better equip students to make strategic alliances across professions, disciplines, and systems to address contemporary environmental crises.
On-line predicting diesel engine EGR rate based on Chaos-Neural Networks

To counter the influencing emission of the diesel engine by the EGR rate, the forecasting model of the diesel engine EGR rate was set up by combining Radial Basis Function neural network (RBFNN) with the Chaos-Neural Networks (CNN) theory. Based on the nonlinear and effective modeling capabilities of the chaos system, the emissions performance and the EGR rate of the diesel engine were on-line predicted by the evolution on approximating to phase points of the RBF neural network; the predicting results were compared with the gray prediction results. The tests on the EGR rate and the diesel engine emission were made on the whole vehicle by the chaos-neural networks synergetic strategy. The test result showed that the forecasting model of the diesel engine EGR rate was reasonable; the chaos-neural networks forecasting strategy had the good resolving power and could be much fitted for the on-line forecast of the EGR rate.
Effect of Nurses Living Fit™ Exercise and Nutrition Intervention on Body Mass Index in Nurses

Objective: The hospital-based Nurses Living Fit (NLF) intervention was implemented by nurses to determine its effect on decreasing body mass index (BMI) in nurse participants. Background: Although there are limited data on obesity rates of nurses working in the United States, more than half are estimated to be overweight or obese. Methods: The NLF intervention included exercise (12 weekly sessions), yoga and nutrition (4 monthly sessions), and diary completion (exercise/yoga, food/water consumption, and sleep), addressing healthy lifestyle principles. Results: NLF participants experienced a greater mean reduction in BMI and waist circumference inches. Ninety-three percent of NLF participants recommended the NLF program. Conclusions: Provision of an evidence-based program such as NLF facilitates nurse education on healthy lifestyle principles.
Vitamin D receptor agonists regulate ocular developmental angiogenesis and modulate expression of dre‐miR‐21 and VEGF

Pathological growth of ocular vasculature networks can underpin visual impairment in neovascular age‐related macular degeneration, proliferative diabetic retinopathy and retinopathy of prematurity. Our aim was to uncover novel pharmacological regulators of ocular angiogenesis by phenotype‐based screening in zebrafish.
Formal Ver ification of Workflow Schemas

Practical experience indicates that the definition of real-world workflow applications is a complex and error-prone process. Existing workflow management systems provide the means, in the best case, for very primitive syntactic verification, which is not enough to guarantee the overall correctness and robustness of workflow applications. The report introduces a method for formal verification of system behaviour which, in C3DS, is defined as workflow schemas. Workflows are modelled by means of an automata-based method, which facilitates exhaustive compositional reachability analysis. The workflow behaviour is checked against safety properties, which can be either generic (applicable to all workflow schemas) or domain specific (applicable to a given schema). The analysis is performed in an automated way using the LTSA toolkit, which is accessible by designers who are not experts in formal methods.
Bingo! Externally supported performance intervention for deficient visual search in normal aging, Parkinson's disease, and Alzheimer's disease

ABSTRACT External support may improve task performance regardless of an individual's ability to compensate for cognitive deficits through internally generated mechanisms. We investigated if performance of a complex, familiar visual search task (the game of bingo) could be enhanced in groups with suboptimal vision by providing external support through manipulation of task stimuli. Participants were 19 younger adults, 14 individuals with probable Alzheimer's disease (AD), 13 AD-matched healthy adults, 17 non-demented individuals with Parkinson's disease (PD), and 20 PD-matched healthy adults. We varied stimulus contrast, size, and visual complexity during game play. The externally supported performance interventions of increased stimulus size and decreased complexity resulted in improvements in performance by all groups. AD also obtained benefit from increasing contrast, presumably by compensating for their contrast sensitivity deficit. The general finding of improved performance across healthy and afflicted groups suggests the value of visual support as an easy-to-apply intervention to enhance cognitive performance.
Topic Tracking in a News Stream

In this paper we describe a Topic Tracking system based on unigram models, submitted by Dragon Systems in the December 1998 Topic Detection and Tracking (TDT) Evaluation. We focus on the most recent developments, including improvements in the smoothing of sparse unigram models, a better discriminator, and the implementation of unsupervised adaptation. We give results on the default test conditions, namely, tracking in newswire and automatically recognized broadcast given four story samples, as well as several variations: one story sample, automatically recognized broadcast only, and automatically recognized broadcast with automatically determined story boundaries. Finally, we show the effect of interpolating this system with Dragon’s other tracking system based on a BetaBinomial model.
Nicotine-induced impairments of spatial cognition and long-term potentiation in adolescent male rats

The aim of the present study was to investigate whether cognitive behavioral impairment, induced by nicotine in offspring rats, was associated with the alteration of hippocampal short-term potentiation (STP) and long-term potentiation (LTP) and to discuss the potential underlying mechanism. Young adult offspring rats were randomly divided into three groups. The groups include: control group (CC), nicotine group 1 (NC), in which their mothers received nicotine from gestational day 3 (GD3) to GD18, and nicotine group 2 (CN), in which young adult offspring rats received nicotine from postnatal day 42 (PD42) to PD56. Morris water maze (MWM) test was performed and then field excitatory postsynaptic potentials elicited by the stimulation of perforant pathway were recorded in the hippocampal dentate gyrus region. The results of the MWM test showed that learning and memory were impaired by either prenatal or postnatal nicotine exposure. In addition, it was found that there was no statistical difference of the MWM data between both nicotine treatments. In the electrophysiological test, LTP and STP were significantly inhibited in both NC and CN groups in comparison with the CC group. Notably, STP in CN group was also lower than that in the NC group. These findings suggested that both prenatal and postnatal exposure to nicotine induced learning and memory deficits, while the potential mechanism might be different from each other due to their dissimilar impairments of synaptic plasticity.
Hepatitis C virus genotypes in northern Italy: clinical and virological features

We analyzed the characteristics of subjects from the same area who were infected with hepatitis C virus genotypes 1 through 4 and subtypes 1a and 1b. Our data are consistent with a rapid evolution in the epidemiology of HCV genotypes and argue against different pathogenic potentials for genotypes 1b and 2.
Recognizing Exponential Inter-Contact Time in VANETs

Inter-contact time between moving vehicles is one of the key metrics in vehicular ad hoc networks (VANETs) and central to forwarding algorithms and the end-to-end delay. Due to prohibitive costs, little work has conducted experimental study on inter-contact time in urban vehicular environments. In this paper, we carry out an extensive experiment involving thousands of operational taxies in Shanghai city. Studying the taxi trace data on the frequency and duration of transfer opportunities between taxies, we observe that the tail distribution of the inter-contact time, that is the time gap separating two contacts of the same pair of taxies, exhibits a light tail such as one of an exponential distribution, over a large range of timescale. This observation is in sharp contrast to recent empirical data studies based on human mobility, in which the distribution of the inter-contact time obeys a power law. By performing a least squares fit, we establish an exponential model that can accurately depict the tail behavior of the inter-contact time in VANETs. Our results thus provide fundamental guidelines on design of new vehicular mobility models in urban scenarios, new data forwarding protocols and their performance analysis.
Attitudes Toward Gay Men and Lesbian Women Among Heterosexual Social Work Faculty

This study reports results from a national Internet-based survey administered anonymously to a cross-section of social work faculty in the United States. Drawn from a sampling frame of 700 accredited or in candidacy schools, data were collected between November 2010 and March 2011. We investigate the role of sex, sexual orientation, race, religious affiliation and beliefs, religiosity, political ideology, sexism, and interest in sexuality/LGBTQ issues. Race, religiosity, political ideology, and sexism are associated with sexual prejudice, which was endorsed among a small percentage (14%) of the sample (n = 303). Outcome scores were not statistically different based on the targets’ sex. Strategies are recommended to reduce sexual prejudice among social work faculty and to increase institutional support for acceptance in the academy.
Evaluation of PIMATM CD4 System for Decentralization of Immunological Monitoring of HIV-Infected Patients in Senegal

Background HIV infection is a concern in the army troupes because of the risk behaviour of the military population. In order to allow regular access to CD4+ T cell enumeration of military personnel as well as their dependents and civilians living with HIV, the Senegalese Army AIDS program is implementing PIMATM Alere technology in urban and semi-urban military medical centres. Validation such device is therefore required prior their wide implementation. The purpose of this study was to compare CD4+ T cell count measurements between the PIMATM Alere to the BD FACSCountTM. Methodology We selected a total of 200 subjects including 50 patients with CD4+ T-cells below 200/mm3, 50 between 200 and 350/mm3, 50 between 351 and 500/mm3, and 50 above 500/mm3. CD4+ T-cell count was performed on venous blood using the BD FASCountTM as reference method and the PIMATM Point of Care technology. The mean biases and limits of agreement between the PIMATM Alere and BD FACSCountTM were assessed with the Bland-Altman analysis, the linear regression performed using the Passing-Bablok regression analysis, and the percent similarity calculated using the Scott method. Results Our data have shown a mean difference of 22.3 cells/mm3 [95%CI:9.1–35.5] between the BD FACSCountTM and PIMATM Alere CD4 measurements. However, the mean differences of the two methods was not significantly different to zero when CD4+ T-cell count was below 350/mm3 (P = 0.76). The Passing-Bablok regression in categorized CD4 counts has also showed concordance correlation coefficient of 0.89 for CD4+ T cell counts below 350/mm3 whilst it was 0.5 when CD4 was above 350/mm3. Conclusion Overall, our data have shown that for low CD4 counts, the results from the PIMATM Alere provided accurate CD4+ T cell counts with a good agreement compared to the FACSCountTM.
Experimental evaluation of BBR congestion control

BBR is a recently proposed congestion control. Instead of using packet loss as congestion signal, like many currently used congestion controls, it uses an estimate of the available bottleneck link bandwidth to determine its sending rate. BBR tries to provide high link utilization while avoiding to create queues in bottleneck buffers. The original publication of BBR shows that it can deliver superior performance compared to Cubic TCP in some environments. This paper provides an independent and extensive experimental evaluation of BBR at higher speeds. The experimental setup uses BBR's Linux kernel 4.9 implementation and typical data rates of 10Gbit/s and 1 Gbit/s at the bottleneck link. The experiments vary the flows' round-trip times, the number of flows, and buffer sizes at the bottleneck. The evaluation considers throughput, queuing delay, packet loss, and fairness. On the one hand, the intended behavior of BBR could be observed with our experiments. On the other hand, some severe inherent issues such as increased queuing delays, unfairness, and massive packet loss were also detected. The paper provides an in-depth discussion of BBR's behavior in different experiment setups.
A scientific workflow supported environment over hybrid infrastructure for aerodynamics design

As computing technologies develop, various studies for e-Science have been actively developed for many years. The advent of Cloud computing, for example, enables scientists to expand their research environments over supercomputers to on-demand and scalable resources. However, several performance drawbacks on the cloud computing can cause considerable obstacles in scientific domains, despite its strong merits. A hybrid infrastructure which consists of the existing and cloud architecture thus can produce a synergy effect for utilizing resources efficiently. In this paper, we proposed hybrid infrastructure-supported a scientific workflow environment for Aerodynamics design and demonstrated its superiority. Hybrid infrastructure covers grid and private cloud computing in this paper. Especially, we focused on improving performance by supporting hybrid infrastructure and efficient usages of physical resources. Since it offers diverse types of computing infrastructures including cloud computing, it can serve elastic resources regardless of the number of tasks for experiments or limitations of space and can reduce costs of time as well as budget during simulations.
Space invaders at Wimbledon: televised sport and deterritorialization.

This analysis of the televising of the 2005 Wimbledon Tennis Championships in the United Kingdom and United States explores how the space of Wimbledon is communicated to different national cultures. The theoretical framing draws on the concepts of deterritorialization developed in Tomlinson’s (1999) work and space invaders as understood by Puwar (2004). A discourse analysis of newspaper reports and television broadcasts demonstrates ways in which the mediation of Wimbledon can be understood as subject to deterritorialization, which opens up the space of Wimbledon to bodies simultaneously marked as insiders and outsiders, revealing tensions around the visibility and invisibility of bodies. We conclude by pointing to the potential of these tensions for disrupting the power dynamics of sport.
THE STUDY OF GROWTH IN THALASSEMIC PATIENTS AND ITS CORRELATION WITH SERUM FERRITIN LEVEL

Background Beta-thalassemia is a common hereditary hemoglobinopathy, which is a reason of microcytic hypochromic anemia. Patients with major thalassemia require multiple blood transfusions. This study evaluated growth in thalassemic patient and relationship with ferritin level. Materials and Methods This is a cross sectional study on seventy patients (36 boys, 34girls) with transfusion dependent major thalassemia at the special diseases center of Yazd. Their age rang was 2 to 28 year. All of them received chelating therapy (Deferoxamine) every night. Weight, height, body mass index (BMI) and serum ferritin of patients were recorded. Results
Pdgfrb‐Cre targets lymphatic endothelial cells of both venous and non‐venous origins

The Pdgfrb‐Cre line has been used as a tool to specifically target pericytes and vascular smooth muscle cells. Recent studies showed additional targeting of cardiac and mesenteric lymphatic endothelial cells (LECs) by the Pdgfrb‐Cre transgene. In the heart, this was suggested to provide evidence for a previously unknown nonvenous source of LECs originating from yolk sac (YS) hemogenic endothelium (HemEC). Here we show that Pdgfrb‐Cre does not, however, target YS HemEC or YS‐derived erythro‐myeloid progenitors (EMPs). Instead, a high proportion of ECs in embryonic blood vessels of multiple organs, as well as venous‐derived LECs were targeted. Assessment of temporal Cre activity using the R26‐mTmG double reporter suggested recent occurrence of Pdgfrb‐Cre recombination in both blood and lymphatic ECs. It thus cannot be excluded that Pdgfrb‐Cre mediated targeting of LECs is due to de novo expression of the Pdgfrb‐Cre transgene or their previously established venous endothelial origin. Importantly, Pdgfrb‐Cre targeting of LECs does not provide evidence for YS HemEC origin of the lymphatic vasculature. Our results highlight the need for careful interpretation of lineage tracing using constitutive Cre lines that cannot discriminate active from historical expression. The early vascular targeting by the Pdgfrb‐Cre also warrants consideration for its use in studies of mural cells. genesis 54:350–358, 2016. © 2016 The Authors.
