SEXUAL AND REPRODUCTIVE HEALTH NEEDS AND PRACTICES: A COMPARATIVE STUDY OF HIV DISCORDANT AND CONCORDANT COUPLES ACCESSING CARE AT COMPREHENSIVE HEALTH CENTERS IN A SOUTHEASTERN STATE IN NIGERIA

Background: A comprehensive picture of the sexual and reproductive health needs and practices of HIVdiscordant couples is key in improving the efficacy of interventions for them. Objective: To compare the sexual and reproductive health needs and practices of HIV discordant and concordant couples in comprehensive health centers in Anambra state, Nigeria. Materials and methods: This was a cross-sectional comparative study of 289 (148 HIV-concordant and 141 HIV-discordant) couples, selected using multistage sampling technique. Quantitative data were collected by interview using semi-structured questionnaire and analysed with statistical package for social sciences version 22.0. Chi-square and fishers exact tests were used to determine statistically significant associations between variables. A p value < 0.05 was significant. Qualitative data were elicited by focus group discussions. Results: More concordant couples 142(49.3%), compared to 122(42.4%) discordant counterparts were sexually active (p = 0.001); more discordant couples had sexual concerns to share (p = 0.05); 74(26.3%) concordant couples compared to 68(23.5%) discordant ones, had children post HIV diagnosis (p= 0.255); while. 77(26.6%) concordant couples desire to have children compared to 70(24.2%) discordant ones (p = 0.731). Eight (2.8%) concordant and none of the discordant couples, practiced artificial conception methods, (p=0.007), the primary reason for not practicing artificial methods, among concordant couples was the feeling it was unnecessary, while for discordant couples, was poor knowledge (p = 0.01). Conclusion: This study found variations in use of condoms; knowledge and or practice of family planning methods, emergency contraception, artificial contraception as well as sexual concerns to share among discordant and concordant couples. We recommend that these findings be factored in designing novel couple-level intervention strategies.

A Robust Scheme for Keyword Based Search over Relational Databases

— Keyword - based search is the most popular paradigm opted by traditional search engines where a user can specify a string of keywords and expect to retrieve relevant documents, possibly ranked by their relevance to the query. While searching within relational database systems, user needs to learn SQL and to know the schema of the underlying data to pose simple searches. This is a substantial barrier for casual users, such as users of Web-based information systems. Therefore, there is a need of a system that can eliminate this requirement is needed. To accomplish this task, this paper proposes a novel technique that is based on conventional keyword-based search and this technique is applied over relational databases. User has to give his/her query in the form of keywords like Google to get the desired results from database. The implementation of this query processing scheme gives efficient result.
Executable Specifications with Scrum: A Practical Guide to Agile Requirements Discovery

Most books about specifications still assume that requirements can be known up front and wont change much during your project. In todays real world, however, you must specify and build software in the face of high and continuing uncertainty. Scrum and other agile methods have evolved to reflect this reality. Now, theres a complete guide to specifying software in agile environments when prerequisites are unclear, requirements are difficult to grasp, and anything about your project could change. Long-time agile coach and enterprise architect Mario Cardinal shows how to create executable specifications and use them to test software behavior against requirements. Cardinal shows how to trawl requirements incrementally, step-by-step, using a vision-centric and emergent iterative practice that is designed for agility. Writing for analysts, architects, developers, and managers, Cardinal makes a strong case for the iterative discovery of requirements. Then, he moves from theory to practice, fully explaining the technical mechanisms and empirical techniques you need to gain full value from executable specifications. Youll learn to connect specifications with software under construction, link requirements to architecture, and automate requirements verification within the Scrum framework. Above all, Cardinal will help you solve the paramount challenge of software development: not only to solve the problem right, but also to solve the right problem. You will learn how to Establish more effective agile roles for analysts and architects Integrate and simplify the best techniques from FIT, ATDD, and BDD Identify core certainties on which your project team should rely to ensure requirements discovery Manage uncertainty by discovering stakeholder desires through short feedback loops Specify as you go while writing small chunks of requirements Use storyboarding and paper prototyping to improve conversations with stakeholders Express stakeholder desires that are requirements with user stories Refine your user stories, and plan more effective Scrum sprints Confirm user stories by scripting behaviors with scenarios Transform scenarios into automated tests that easily confirm your softwares expected behavior as designs emerge and specifications evolve Ensure higher-quality software by specifying nonfunctional requirements
IRMOR: A Method for Image Segmentation and Retrieval Using Mean shift Segmentation and Flood Fill Algorithm

— Nowadays image retrieval plays an important role in an extraordinary number of multimedia applications which serve human society. Since a generic graph based retrieval scheme working in every situation can be quite difficult to implement due to the presence of complex scene. In this paper we investigate to deal with such problems and focuses on how to extract the object from an image using topological models. It begins with the innovative concept of initial low level segmentation of input image, which are used to construct topological model on the basis of connected regions. Using this topological model we have design a new prototype known as Iterative Region Merging and Object Retrieval (IRMOR). Using this prototype IRMOR we can extract contour based descriptors on an object from an image which contain the high level features. In addition we focus on how to apply a region labeling and flood fill method to extract object after formation of object contour, IRMOR have special application such an image matching, object recognition, content based image retrieval, object tracking etc.
Incidence of unexpected red blood cell antibodies in the north of China

This study aimed to investigate the frequency of unexpected antibodies and evaluate the cumulative incidence of additional unexpected antibodies in Beijing. From January 1, 2011 to December 31, 2014, blood samples from 2,095 patients from 98 medical institutes in Beijing were sent to the Beijing Red Cross Blood Center for antibody identification. Of the unexpected antibodies, 29.5% were autoantibodies and 70.5% were alloantibodies. Anti-E was the most prevalent form of allo-antibodies ( n = 445), accounting for 52.9% of the Rh system, followed by anti-M (76.6% of the MNS system) and then 142 cases of anti-C,e, 128 cases of anti-E,c, and 113 cases of anti-Le a . The cumulative incidences of additional antibodies were 0.55% (after the first transfusion), 1.82% (second time), 2.33% (fourth time), 3.07% (firth time), and 4.24% (seventh time). Antibody against the Rh system was the most prevalent, followed by antibodies against MNS, Lewis, Kidd, P1, and Duffy.
MODELING AND CONTROL OF HYBRID PV-WIND ENERGY GENERATION SYSTEM FOR EFFICIENCY IMPROVEMENT

Renewable energy sources have attracted wide attention due to their advantages of being abundant in nature and nearly non-polluting. The most feasible and reliable Grid connected renewable energy systems are the hybrid wind-solar sources. This paper proposes a high performance power generation of hybrid solar photovoltaic (PV) with a large capacity doubly fed induction generator (DFIG) based wind energy system. The proposed scheme uses both the grid side converter (GSC) and rotor-side converter (RSC) of DFIG to inject PV power to the grid. This proposed scheme provides an elegant and economic integration of PV source and DFIG-based wind energy source. A Maximum Power Point Tracking (MPPT) extracted from the wind based rotor speed control is proposed in conjunction with pitch control to avoid overloading in case of high wind velocity over the rated value. The integrated GSC and RSC control is designed to implement the dc-link voltage control, active and reactive power, and grid voltage support control functions. The PV solar is connected directly to the dc-link. A nonlinear control is applied to extract Maximum Power from the PV under variable operating conditions. The proposed scheme does not hamper MPPT of PV and wind sources except during very rarely occurring environmental glitches, which the PV power control algorithm is suitably geared to handle using an artificial neural network (ANN). The developed model is validated through a comprehensive set of simulation studies in the Matlab/Simulink environments. A series of results are obtained in order to analysis the system performance under variable operating conditions. DFIG of individual and This paper shows how the integrated GSC and RSC control is designed to implement the maximum power extraction, the dc-link control, active and reactive power, and grid voltage support control functions. The hybrid system with MPPT has been implemented and simulated using MATLAB/ Simulink environment. The system has been tested for different wind speed and PV irradiations conditions. The simulation results have been analyzed, it is shown that the generation system will supply constant voltages with varying wind speed and irradiation. The PV and the wind systems operate at MPP during most of the time. Also results illustrate that the rotor active power varies under variable wind speed. In sub synchronous mode of operation, the rotor absorbed the active power from the grid or it absorbs a portion from the PV generated power. That in turn lowers the KVA rating of the GSC and also its cost. In super synchronous mode of operation, the gives its power to the grid. This mode of operation happens at of irradiance. This in turn insures the overloading of GSC is At the worst cases of operation during a and conditions occurring simultaneously, GSC by the generated power. The of GSC.

in Mice Strongyloides stercoralis Immunity to Larval Role of IL-5 in Innate and Adaptive

Protective immunity to Strongyloides stercoralis infective larvae in mice has been shown to be dependent on IL-5 based on mAb depletion studies. The goal of this study was to determine the functional role of IL-5 during the innate and adaptive immune response to larval S. stercoralis in mice. In these studies, three strains of mice were used: wild-type C57BL/6J (WT), IL-5 knockout (KO), and IL-5 transgenic (TG). Innate responses to the larvae indicated that there was enhanced survival in the KO animals and decreased survival in the TG animals compared with WT. Furthermore, killing of larvae in TG mice was associated with eosinophil inﬁltration and degranulation. In studying the adaptive immune response, it was observed that immunization of KO mice did not lead to the development of protective immunity. Experiments were then performed to determine whether KO mice reconstituted with Abs or cells could then develop protective immunity. KO mice displayed protective immunity via a granulocyte-dependent mechanism following injection of puriﬁed IgM from immune wild-type animals. Immunity in KO mice could also be reconstituted by the injection of eosinophils at the time of immunization. These eosinophils did not participate in actively killing the challenge infection, but rather were responsible for the induction of a protective Ab response. We conclude that IL-5 is required in the protective immune response for the production of eosinophils, and that eosinophils were involved in larval killing during innate immunity and in the induction of protective Abs in the adaptive immune response. The Journal of Immunology, 2000, 165: 4544–4551. induction of adaptive immunity that they are nonessential as end stage effector cells for larval killing.
Critical Analysis of Anomaly Intrusion Detection Techniques in MANET

- As mobile ad hoc network (MANET) has become very important technology, research concerning its security problem, especially, in intrusion detection has attracted many researchers. Various approaches have been proposed for intrusion detection in mobile network. However, little research work has been done in actually implementing them, especially for anomaly detection in mobile networks. Due to vulnerabilities introduced by mobility, anomaly based detection techniques are more crucial in MANET than misuse based detection technique. This paper focuses on various anomaly detection techniques for MANET and perform critical analysis in various methods of anomaly intrusion detection.
Physics of electrical treeing in Silicon Gel

Silicone gel is commonly employed in electrical insulation, especially in power module encapsulation. In the recent years, the increase of the operation voltage of this application led to a higher electrical stress on the silicone gel, thus, electrical treeing has become a serious issue to the reliability of power modules. In this research, the degradation produced by the electrical treeing has been evaluated dividing it into two main parts: the tree inception and the tree growth, which have been assessed for different waveforms of the applied voltage. The tree inception, the preliminary stage of this phenomenon, has been tested and an innovative model has been proposed explaining this stage. The tree growth has been evaluated in function of the waveform voltage obtaining useful comparisons between the possible electrical stresses. This thesis highlights the peculiar behavior of silicone gel under high electric field and furnishes useful guidelines for designing and testing the electrical insulation made by silicone gel.
Effect of Loneliness on Self Esteem of High School Boys and Girls

The present study attempts to examine the effect of loneliness on self esteem of high school boys and girls, and to see if there is any gender difference existing in the feeling of loneliness and level of self esteem among high school boys and girls. The sample for the study comprised of 120 high school students, out of which 60 were boys and 60 were girls between the age range of 11 to 14 years. Test materials used to assess loneliness and self esteem among high school boys and girls are Daniel W.Russell’s UCLA Loneliness Scale (Version 3) and Self Esteem Inventory, the school short form developed by Coopersmith, 1967. Obtained data is analyzed by using Pearson’s correlation coefficient and T-test. Results revealed that that there is a significant relationship between feeling of loneliness and level of self esteem among high school boys. Where as for the high school girls there is found to be no significant relationship between feeling of loneliness and level of self esteem. With respect to finding the gender difference in feeling of loneliness it is seen that there is no significant difference among high school boys and girls. Similarly the findings for gender difference in the level of self esteem it is seen that there is no significant difference among high school boys and girls.
Diagnosing Obstructive Sleep Apnea – Reaching the Body of the Iceberg

resistant HT which is defined as untreated HT due to at least three anti hypertensive drugs [2,18]. Pulmonary HT is another important issue that may be more prevalent in patient with hypoventilation accompanying OSA or obstructive/restrictive lung pulmonary disease may be determined by echo. Diabetic patients may exhibit uncontrolled diabetes due to underlying sleep apnea. Presence of metabolic syndrome itself may also be a clue for clinician especially in a patient with complaints of OSA [3]. Similarly; patient may suffer from recurrent or untreatable rhythm problems [19]. All of these difficult to treat clinical circumferences should remind the clinician OSA.
ENDOSULFAN INDUCED OXIDATIVE STRESS AND BIOCHEMICAL CHANGES IN TESTES OF MICE

Endosulfan is potent toxicogen and carcinogen. It is widely used in agriculture and detected in soil, surface water, and underground water, fruits, vegetables and milk. A number of studies have been performed to investigate the effect of endosulfan on reproductive system. Exposure to endosulfan leads to degeneration of spermatogenesis, lower testosterone level and induce oxidative stress. Swisss albino male mice were grouped as control and endosulfan treated for 4, 8, 12 weeks at animal house of S S Hospital and Research Institute, Patna. Sperm count was performed by routine process, testosterone level was determined by ELISA kit method, and lipid peroxidation was done by measuring MDA level in blood serum. Decrease in testicular weight, sperm count, testosterone level and increase in MDA level were observed when compared with control upon administration of endosulfan at the rate of 3 mg/kg/body weight with significance of (p-value<0.0001). The effect of endosufan on reproductive system is deleterious and insidious. Endosulfan has been used in agriculture widely and enters human body system through food chain to cause toxicity. Hence more studies and investigations are warranted in this field the mechanism by which endosulfan impairs the reproductive system.
Effect of mutation of the TPR and DP2 domains of Sti1 on Hsp90 signaling and interaction in Saccharomyces cerevisiae

Through simultaneous interactions with Hsp70 and Hsp90 via separate tetratricopeptide repeat (TPR) domains, the co-chaperone protein Hop/Sti1 has been proposed to play a critical role in the transfer of client proteins from Hsp70 to Hsp90. However, no prior mutational analysis demonstrating a critical in vivo role for the TPR domains of Sti1 has been reported. We used site-directed mutagenesis of the TPR domains combined with a genetic screen to isolate mutations that disrupt Sti1 function. A single amino acid alteration in TPR2A disrupted Hsp90 interaction in vivo but did not significantly affect function. However, deletion of a conserved residue in TPR2A or mutations in the carboxy-terminal DP2 domain completely disrupted Sti1 function. Surprisingly, mutations in TPR1, previously shown to interact with Hsp70, were not sufficient to disrupt in vivo functions unless combined with mutations in TPR2B, suggesting that TPR1 and TPR2B have redundant or overlapping in vivo functions. We further examined the genetic and physical interaction of Sti1 with a mutant form of Hsp90, providing insight into the importance of the TPR2A domain of Sti1 in regulating Hsp90 function. In this report we examine the effect of STI1 mutation on in vivo functions. We used the YDJ1-STI1 synthetic lethality to determine the effects of site-directed mutations of the TPR domains and also conducted a genetic screen to isolate mutations in STI1 that failed to support viability of a sti1ydj1 strain. We describe the effect of mutation of TPR1, TPR2A and TPR2B, alone and in combination, on growth, assays of Hsp90 client protein activity and Hsp90 interaction. We also describe the effect of mutation or deletion of the DP2 region of Sti1. Our results indicate that TPR2A and the DP2 region have a critical role in Sti1 function and suggest that TPR1 and TPR2B have overlapping or redundant functions. These results raise interesting questions about the structure of Hop/Sti1 and how Hop/Sti1 physically interacts with Hsp70.
Artificial Systems and Models for Risk Covering Operations

Mainly, this paper focuses on the roles of artificial intelligence based systems and especially on risk-covering operations. In this context, the paper comes with theoretical explanations on real-life based examples and applications. From a general perspective, the paper enriches its value with a wide discussion on the related subject. The paper aims to revise the volatilities’ estimation models and the correlations between the various time series and also by presenting the Risk Metrics methodology, as explained is a case study. The advantages that the VaR estimation offers, consist of its ability to quantitatively and numerically express the risk level of a portfolio, at a certain moment in time and also the risk of on open position (in titles, in FX, commodities or granted loans), belonging to an economic agent or even individual; hence, its role in a more efficient capital allocation, in the assumed risk delimitation, and also as a performance measurement instrument. In this paper and the study case that completes our work, we aim to prove how we can prevent considerable losses and even bankruptcies if VaR is known and applied accordingly. For this reason, the universities inRomaniashould include or increase their curricula with the study of the VaR model as an artificial intelligence tool. The simplicity of the presented case study, most probably, is the strongest argument of the current work because it can be understood also by the readers that are not necessarily very experienced in the risk management field.
A robust test for serial correlation in panel data models

Abstract We consider a new nonparametric test for serial correlation of unknown form in the estimated residuals of a panel regression model, where individual and time effects can be fixed or random, and the panel data can be balanced or unbalanced. Our test is robust against potential weak error cross-sectional dependence and error serial dependence in higher-order moments. This is in contrast to existing tests for serial correlation in panel data models, which assume error components to be cross-sectionally and serially independent. Our test has an asymptotic N(0, 1) distribution under the null hypothesis and is consistent against serial correlation of unknown form. No common alternative is assumed and hence our test allows for substantial inhomogeneity in serial correlation across individuals. A simulation study highlights the merits of the proposed test relative to a variety of existing tests in the literature. We apply the new test to the empirical study of Wolfers on the relationship between unilateral divorce laws and divorce rates and find strong evidence against serial uncorrelatedness even controlling for the fixed effect.
Divergent evolutionary pathways for aggression and territoriality in Astyanax cavefish

The surface morph of the Mexican tetra fish (Astyanax mexicanus) exhibits strong territoriality behavior and high levels of aggression. In contrast, the eyeless cave-adapted morph from Sierra de El Abra, México, rarely are aggressive and have totally lost the territorial behavior. These behaviors are part of what has been called the cavefish behavioral syndrome. Here, we report that several Astyanax cave populations of Sierra de Guatemala, unlike those reported for the Sierra de El Abra cave populations, display significant territoriality and aggression when confined into a reduced space. We discuss divergent evolutionary trajectories in terms of agonistic behavior for cavefish populations inhabiting different mountain ranges.
