Évaluation de l'intérêt de la supplémentation en zinc dans la prévention des complications chez les patients en dialyse péritonéale : état de l’art

Chez les sujets en insuffisance renale chronique au stade terminal, la dialyse peritoneale (DP) est une methode d’epuration extra-renale utilisant le peritoine comme membrane d’echange. Cependant, la presence du catheter au niveau abdominal expose le patient au risque de peritonite, principale complication de la technique. Ainsi, les episodes de peritonite et le phenomene de fibrose, epaississement de la membrane peritoneale, raccourcissent la duree de vie de la methode. De plus, ces patients presentent une forme d’immunodepression et sont sujets a la denutrition proteino-energetique. Par ailleurs, le zinc est un oligo-element indispensable a l’organisme qui possede notamment des proprietes immonumodulatrices. Chez les patients en DP, la denutrition et d'autres facteurs peuvent causer une carence en zinc. Une supplementation en zinc pourrait corriger un deficit preexistant, normaliser les dysfonctions immunitaires et aider ces patients a se defendre contre les infections bacteriennes. Cette these constitue une justification quant a la realisation d’une etude de supplementation en zinc chez les patients en DP dans la prevention de la peritonite et de la fibrose.
REDUCTION OF DIMENSIONALITY OF AN OPTIMAL DECISION TABLE CONVERSION ALGORITHM

A dynamic programming algorithm for converting decision tables to optimal decision trees is analyzed. The complexity of the algorithm may be defined as the dimension of the domain of the minimal-cost functional. Upper bounds for this complexity are derived under various assumptions. Methods of reducing the dimensionality of the problem utilizing lower bounds for decision costs are also discussed.
A p-ADIC HERMITIAN MAASS LIFT

Abstract For K, an imaginary quadratic field with discriminant −DK, and associated quadratic Galois character χK, Kojima, Gritsenko and Krieg studied a Hermitian Maass lift of elliptic modular cusp forms of level DK and nebentypus χK via Hermitian Jacobi forms to Hermitian modular forms of level one for the unitary group U(2, 2) split over K. We generalize this (under certain conditions on K and p) to the case of p-oldforms of level pDK and character χK. To do this, we define an appropriate Hermitian Maass space for general level and prove that it is isomorphic to the space of special Hermitian Jacobi forms. We then show how to adapt this construction to lift a Hida family of modular forms to a p-adic analytic family of automorphic forms in the Maass space of level p.
Addressing Counselor Stigma in Working With Female Intimate Partner Violence Survivors

ABSTRACT Though millions of women are affected by intimate partner violence (IPV) every year, research shows that counselors may have biases against women who survive IPV and may shame them for their experiences. There is a lack of proper counselor training about IPV issues, and this may increase the risk that counselors are not providing clients with the necessary help to move past IPV. This article reviews the literature on counselor bias regarding IPV and offers practical strategies to enhance counselor competence in working with female IPV survivors. Recommendations include exploring and bias stigma, increased training in IPV, and education on state laws and policies.
Feature Selection Using Gram-Schmidt Orthogonalization For Support Vector Regression – A Case Study Of Mortality Rate Prediction Caused By Pneumonia

Feature selection is a technique for finding optimal features among original features by eliminating irrelevant features. Besides improving the learning accuracy and facilitate a better understanding of the model, feature selection may reduce the cost of building, storing and processing models. Recently, a Gram-Schmidt Orthogonalization-based feature selection is proposed for unstructured data. In this paper, we extend this Gram-Schmidt Orthogonalization-based feature selection for structured data. Our simulation shows that this Gram-Schmidt Orthogonalization-based feature selection improves the accuracy of Support Vector Regression in the average of 1.384925% for the case study of the prediction of mortality rates caused by pneumonia.
Study on Issue Price Performance of IPO’s In India: 2010-2014

tock market is most promising sector in an Indian economy for raising the level of Indian financial system. After liberalization phase stock market has proven as a weapon of fighting with the foreign economies. After its inception in 1875 stock market has been played a challenging role for savers as well as for investors. Directions of an economy can be measured by movement of volatility index . Stock Index has been a barometer for measuring the performance of Indian economy with its development. Micro and macro economic factors have continuously affected the industrial growth. Our financial industry has been affected by financial crisis frequently that has proven the stock market full of risk and uncertainty. That was already an unsolved problem for the investors. But CAPM, APT, Portfolio diversification has proven a very effective risk management tools. Nifty and Sensex always have been in the mind of active investors which have changed the life as miracle. Indian stock market has gained new milestones and its volatility has surprised our economy with the expansion in equity, debentures, bonds, real estate, Options, Futures, and Derivatives. Our Indian economy will be the third largest economy after 2035 according to a survey. After getting freedom from Britishers, Indian economy has survived with rebuilding their stand through monetary policies, fiscal policies, five year plans etc. Efficient and effective stock market is that place where prices of the security are showing all related information about that with its true worth.

This paper is an attempt to analyze stock market conditions with all related measure to check on risk management tools with their respective return. With the help of Secondary sources like current research studies, Reports of BSE, NSE this study has been taken further to exploring some new highlights
THE TASMANIAN LEGACY OF MAN AND FIRE

The vegetation of Tasmania is complex and much of it is in a state of disclimax. At the time of European settlement, the proportion of non-forest open vegetation was 370/0, about 5% ofthis at high altitudes. In the present interglacial climate, in regions ofhigh rainfall, where rainforest dominance might be expected, approximately 45% carries sedgeland, grassland, shrub communities and wet sclerophyll forest. Similarly, drier areas carry extensive grassland, sedgeland and heath, instead of dry eucalypt forest. This complexity of distribution and disclimax can be attributed to fire disturbance. Fire not only produces a successional mosaic but, through Ecological Drift, causes extinction ofcommunities. This level ofdisplacement appears to demand a timespan ofhuman-induced fire sufficiently long to affect soil fertility. A palaeontological record of the last five glacial cycles has been analysed from the Darwin Crater in western Tasmania and compared with that from the Chatham Rise, New Zealand. These show parallel behaviour in the proportions of forest and non-forest communities in the earlier cycles. However, the Tasmanian record shows a marked divergence during the Last Glacial cycle, with a twofold increase in open vegetation relative to closed forest. Eucalypt forest increases relative to rainforest, and charcoal increases relative to woody vegetation. These changes occur through a variety ofclimates, including full glacial and optimum interglacial, but are not apparent in the New Zealand core, making it difficult to attribute them to a climatic cause. In the Tasmanian vegetation, they can be explained by an increase in fire frequency, due to human activity. Since their onset occurs in isotopic oxygen stage 4 and continues in the differing climates thereafter, it may be inferred that the 14C dates of the earliest evidence ofoccupation by the Aborigines are gross underestimates. A date ofabout 70 000 yrs BP is more likely. It appears that, when using 14C methodology, such underestimation for dates beyond30 000 yrs BP is to be expected in palaeosamples from western Tasmania.
Your New Paradigm for Understanding and Applying Sonographic Principles

A new paradigm for understanding and applying sonographic principles is needed because two alternative fundamental principles of operation are now present in the array of commercially available sonographic equipment. The first, which is termed conventional sonography, has been the operating principle for more than 50 years. Recently, a second principle has appeared, termed virtual-beam sonography. These two operating principles are fundamentally different, and there are implications for the resulting anatomic images and motion information presented. Virtual-beam sonography improves nearly every aspect of sonographic, anatomic imaging and motion presentation.

LiPLike: towards gene regulatory network predictions of high certainty

Motivation Reverse engineering of gene regulatory networks has for years struggled with high correlation in expression between regulatory elements. If two regulators have matching expression patterns it is impossible to differentiate between the two, and thus false positive identifications are abundant. Results To allow for gene regulation predictions of high confidence, we propose a novel method, LiPLike, that assumes a regression model and iteratively searches for interactions that cannot be replaced by a linear combination of other predictors. To compare the performance of LiPLike with other available inference methods, we benchmarked LiPLike using three independent datasets from the previous DREAM5 challenge. We found that LiPLike could be used to stratify predictions of other inference tools, and when applied to the predictions of DREAM5 participants we observed the accuracy to on average be improved >140% compared to individual methods. Furthermore, we observed that LiPLike independently predicted networks better than all DREAM5 participants when applied to biological data. When predicting the Escherichia coli network, LiPLike had an accuracy of 0.38 for the top-ranked 100 interactions, whereas the corresponding DREAM5 consensus model yielded an accuracy of 0.11. Availability We made LiPLike available to the community as a Python toolbox, available at https://gitlab.com/Gustafsson-lab/liplike. We believe that LiPLike will be used for high confidence predictions in studies where individual model interactions are of high importance, and that LiPLike will be used to remove false positive predictions made by other state-of-the-art gene-gene regulation prediction tools.

Farmer perception and valuation of seed quality: Evidence from bean and cowpea seed auctions in Tanzania and Ghana

Double blind field experiments and experimental auctions were conducted with bean and cowpea farmers in Tanzania and Ghana to gauge the relative demand for three types of seed products that differ in price and quality: certified, quality declared, and recycled. Whether the cost differential makes these seeds qualitatively different products as reflected in their perceived performance, and whether that translates into farmers’ willingness to pay price premiums, are the research questions addressed by this study. Results indicate that, all else equal, there were significant differences in the perceived quality of the seed products evaluated. Farmers were willing to pay significantly more for their higher rated seed relative to their lower rated seeds. However, for a majority of farmers the magnitude of the premium they are willing to pay for a higher quality seed is less than the current price differential between certified seed and grain. Research and policy implications of these results for legume seed system are discussed.
Produção, caracterização e avaliação das atividades antioxidante e antitumoral de oligossacarídeos de quitosana obtidos a partir dos resíduos do processamento do camarão marinho Litopenaeus vannamei

Chitosan is a pseudonatural non-toxic biodegradable polysaccharide, with cationic nature which has several biotechnological applications. However, its high molecular weight results in low solubility at neutral pH and its high viscosity limits its uses in human cosmetic products, food, pharmaceuticals and agriculture industries. The production of chitosan oligosaccharides is an effective way to improve the chitosan solubility and decrease its viscosity, thereby enhancing its application. Accordingly, this work aimed to produce and characterize chitosan oligosaccharides (COS) obtained from the residues of the marine shrimp Litopenaeus vannamei process and evaluate their antioxidant, cytotoxic, agude toxicity, analgesic and antitumor activity. Chitosan was produced from shrimp heads by enzymatic autolysis, followed by enzymatic hydrolysis for 20 hours at 40 ° C using pepsin resulting in chitoligosaccharides and low molecular weight chitosan. The characterization was performed by infrared spectroscopy (FT-IR), nuclear magnetic resonance (NMR) C and mass spectrometry (MALDI-TOF). To determine the antioxidant potential of COS experiments using ABTS, reducing power and chelating potential of Fe2+ were evaluated, and to understand the protection of DNA biomolecule, the Fenton reaction was performed. The cytotoxicity was evaluated using NCI-H292, HT-29, MCF-7 and Hep-2 human tumor cell lines. We evaluated the acute toxicity of these compounds in mice, as well as the analgesic and antitumor activity in vivo. The oligosaccharides produced showed complete solubility and low viscosity in aqueous media. The FT-IR and NMR charts showed a profile close to that of chitosan. When analyzed by MALDI-TOF, oligosaccharides showed a molecular weight between 0.8-2.6 kDa. The antioxidant activity for ABTS was of 37.94%, chelating abilities on ferrous ions was of 22.38 % at 1 mg/mL and exhibited DNA protection for 100 μM. COS obtained did not show cytotoxicity in 25μM. The compounds showed analgesic activity dose dependent and interesting ability to tumor inhibition in vivo. For Ehrlich carcinoma tumors COS inhibited 61.8% while for sarcoma 180, COS inhibited 63.1%, of the growth of tumor in mice These results show the efficiency of these oligomers obtained from shrimp waste heads, which have similar structures to those of chitosan, allowing the improvement of its properties. Future studies are important to determine clearly the biological activities of these compounds.
The carbohydrates of Agave vera cruz Mill.

In a preliminary communication from this Laboratory, Srinivasan, Bhalerao & Subramanian (1952) reported the presence of polyfructosans in the stem of Agave vera cruz (hereinafter referred to as the agave; for description of this species, see Firminger, 1905; Duthie, 1915; Bailey, 1919). This material has since been shown by chromatographic methods to contain a number of other water-soluble carbohydrates (Bhatia, Satyanarayana & Srinivasan, 1953). The carbohydrate make-up in the stem of the agave appears, in general, to be similar to that reported by Dedonder (1950) and by Bacon & Edelman (1951) in Jerusalem artichoke. However, neither of the two polyfructosans isolated from the agave seems to be identical with inulin.
Analysis of the urban heat island in representative points of the city of Bayeux / PB

Abstrat Urban growth has generated several socio-environmental problems and has altered the quality of life of people living in these environments. Due to the disorderly growth of cities and the various forms of urban land use and occupation, changes in the thermal field of these areas have occurred and caused the formation of urban heat islands and thermal discomfort in urban environments. Thus, the need to understand the formation of heat islands in these areas and the study of their causes and consequences grows. Given this context, the present work intends to study the urban climate of the city of Bayeux / PB, specifically the urban thermal field, and the formation of heat islands. For the accomplishment of the research, initially a bibliographical survey of the subject in question was made. Subsequently experimental points of meteorological data collection (temperature and relative air humidity) were defined in the metropolitan area of the city of Joao Pessoa, specifically in the municipality of Bayeux / PB. These points were defined based on the different types of land use and cover in the study area. The following experimental points were defined: a point in the center of the city of Bayeux / PB, another point on the banks of the BR230 direction Bayeux, and a reference point in a remnant of Atlantic forest. To obtain the urban heat island the reference point was used as a parameter of the climatic conditions of a natural environment. The data of temperature and relative humidity were collected through thermometers (HOBO U-10), which were placed on steel tripods (1.5 meters high) and monitored at uninterrupted intervals of 1 and 1 hour during the dry period and rainy region. The analysis of the data points to the formation of urban heat islands in the two periods evaluated in the city of Bayeux / PB, being the center of the city, the most critical area with the most intense heat islands. The vegetative cover played a predominant role in the climatic mitigation of the experimental samples as well as the presence of precipitation. The areas with impermeable soil cover presented the largest heat islands and contributed to the thermal discomfort of the study area. Keywords: Urban Climate, Thermodynamic Field, Urban Heat Island.

Design and fabrication of touch-sensitive polymeric optical fibre (POF) fabric

Abstract Polymeric optical fibres (POFs) can be integrated into a textile structure for illuminative fashion and interior fabric applications. In this study, the development of a touch-sensitive POF fabric system through the integration of conductive yarns and an electronic controlling system was explored. Distinct from conventional sensor applications, the capacitive sensor used in this study was embedded into the textile structure using conductive yarns via experimentations with different weave structures. With the embedded controlling system and RGB light-emitting diodes, the POF fabrics were able to transfer sensory signals into illumination. This study combined novel weaving techniques, different materials and electronic system development to develop a multi-touch interface based on textile capacitive sensors that can sense both touch contact and non-contact/proximity. The final prototype can be washed up to 10 laundry cycles. The results demonstrated that multiple functionalities can be integrated into the structure to produce an interactive textile based product.
Investigating Attrition Among Special Educators in Relation to Bronfenbrenner's Ecological Theory

Investigating Attrition Among Special Educators in Relation to Bronfenbrenner’s Ecological Theory by Meta Jane Turner MAT, Walden University, 2011 BGS, University of Connecticut, 2008 Doctoral Study Submitted in Partial Fulfillment of the Requirements for the Degree of Doctor of Education Walden University April 2019 Abstract Special education teacher attrition has been an ongoing problem for at least 3 decades. This study specifically focused on the attrition of special education teachers in South Carolina. Attrition can have a negative impact on student learning, making it important to identify the causes of attrition among special education teachers to lower attrition in the state and lessen the negative impact on student learning outcomes. The purpose of thisSpecial education teacher attrition has been an ongoing problem for at least 3 decades. This study specifically focused on the attrition of special education teachers in South Carolina. Attrition can have a negative impact on student learning, making it important to identify the causes of attrition among special education teachers to lower attrition in the state and lessen the negative impact on student learning outcomes. The purpose of this quantitative correlational study was to examine attrition whether career satisfaction, perceived administrative support, coping with job-related stress, and attitudes toward students are related to attrition in special education teachers in South Carolina. Bronfenbrenner’s ecological theory served as the theoretical framework. In accordance with the study purpose, the research questions for this study assessed the relationship between career satisfaction, perceived administrative support, coping with job-related stress, attitudes toward students, and special education teachers’ intent to remain in the field of special education. Data were collected via self-report survey responses from special education teachers from South Carolina and were analyzed thorough use of multinomial logistic regressions. The findings of the multinomial logistic regressions showed that career satisfaction and coping with job-related stress were significant predictors of intent to remain in special education. Perceived administrative support and attitude toward students were not significant predictors of intent to remain in special education. Implications include finding ways to reduce job-related stress for special education teachers. This study contributed to positive social change through the discovery of the reasons why special educators are leaving the field, which could lead to possible ways to alleviate attrition.
