Lecture on the endocrine system in the course of histology introduces students to new insights on the morphological and functional features of the endocrine glands and their hormonal activity and the effect on the body. The endocrine system, along with the nervous and immune system, is among the regulatory and integrating systems of the body. It controls the regulation of the body's most important functions: growth, reproduction, proliferation and differentiation of cells, metabolism and energy, secretion, excretion, absorption, and other behavioral reactions. In general, the function of the endocrine system is defined as the maintenance of homeostasis

Psychometrically and qualitatively validating a cross-national cumulative measure of fear-based xenophobia

.40. The result, a cross-national 5-item scale measuring fear-based xenophobia, was tested by means of the Three-step Test-Interview (Hak, Van der Veer and Jansen 2008) with 10 students in The Netherlands and 10 students in Norway. The analysis of these qualitative interviews shows that individual respondents’ criteria for the ranking of the scale items strongly depend on the way immigrants are framed. Ranking according to different levels of fear turned out to be only one criterion out of several possible ones used by individual respondents. Keywords Xenophobia . Measurement .

МЕТАЛЛОУГЛЕРОДНЫЕ НАНОКОМПОЗИТЫ НА ОСНОВЕ ПИРОЛИЗОВАННОГО ПОЛИАКРИЛОНИТРИЛА

The electronic structure and geometry of metal−carbon nanocomposites based on the pyrolyzed poliacrylonitril (PPAN) with Cu, Si, Fe, Co, Ni atoms using the DFT method have been theoretically studied. The effect of nitrogen on the stability of PPAN and its conductivity has been determined. The electrophysical properties and structure of metal nanocomposites have been studied using the XFA method. The composites have been produced by IR heating. We suggest that metal−carbon nanocomposites form due to the special processing of the (PAN−MeR) samples. Metal nanoparticles are regularly dispersed in the nanocristalline matrix of PPAN. The conductivity of this metal−carbon nanocomposites has an activation character and varies from10−1 to 103 Om/sm depending on synthesis temperature (T = 600—900 °С). The results of theoretical and experimental research are in good agreement. Теоретически изучена структура и электронно−энергетическое строение металлоуглеродных нанокомпозитов на основе пиролизованного полиакрилонитрила (ППАН), легированного атомами меди, кремния, железа, кобальта, никеля, с использованием неэмпирического метода функционала плотности. Определено влияние азота, входящего в состав ППАН, на стабильность нанокомпозитов и их проводящее состояние. Методом РФА экспериментально изучена структура, а также исследованы электрофизические свойства нанокомпозитов, полученных под действием ИК−нагрева на основе ПАН и соединений соответствующих металлов. Установлено, что в результате обработки прекурсоров, представляющих собой системы ПАН− МеR (где Ме — Cu, Co, Ni, Fe; R — хлорид ион, ацетат−ион), формируются металлоуглеродные нанокомпозиты, в которых наночастицы металлов равномерно распределены в нанокристаллической углеродной матрице на основе ППАН. Показано, что электропроводность металлоуглеродных нанокомпозитов носит активационный характер, определяется температурой синтеза нанокомпозитов и изменяется от 10−1 до 103 См/см в интервале температур получения Т = 600÷900 °С. Энергия активации проводимости также определяется температурой синтеза, что объясняется изменениями в структуре и химическом составе получаемых материалов. Установлено, что результаты расчета энергетических характеристик нанокомпозита согласуются с экспериментом.

Гидроэнергетика - национальный ресурс Беларуси

The main reason of return to so called «small hydraulic power engineering», involvement of local hydraulic power resources in power balance of the Republic is significant changes of social and economical conditions of management, acute deficit and high price of local and in^orted resources of fuel, oil, gas, electric power, respectively.The paper analyses hydraulic power engineering potential of the Republic of Belarus. History of the development of hydraulic power engineering in the Republic, program of restoration and construction of hydraulic power stations, some prospective projects that ate planned for realization are presented in the paper.Основной причиной возврата к «малой гидроэнергетике», вовлечения собственных гидроэнергоресурсов в энергобаланс республики явились существенное изменение социально- экономических условий хозяйствования, резкий дефицит собственных и удорожание импортируемых нефти, газа, электроэнергии.Проведен анализ гидроэнергетического потенциала Республики Беларусь, представлены история развития гидроэнергетики в стране, программа восстановления и строительства ГЭС, ряд перспективных проектов, которые намечены к реализации

Ambivalence toward men: comparing sexism among Polish, South African and British university students

This study extends the literature on attitudes toward gender roles by exploring whether the nature of sexism (i.e., benevolence and hostility directed at men) differs among university students from two under-researched countries, Poland (n = 190) and South Africa (n = 188), in a comparison with students in the United Kingdom (n = 166). Based on empirical literature applying Ambivalent Sexism Theory, and in the light of the socio-political context, it was hypothesized that: (1) both hostile and benevolent attitudes toward men in Poland would be more liberal than in South Africa and more conservative than in the United Kingdom, and (2), women would exhibit more hostile but less benevolent attitudes than men in relatively more conservative South Africa. The Ambivalence to Men Inventory was used to measure the two types of sexist attitudes about men. Findings supported the first hypothesis for hostile attitudes and partially for benevolent attitudes. South African and Polish students were more benevolent and hostile to men than British students, and students from South Africa were more hostile than those from Poland. Moreover, as predicted, a significant country-by-gender interaction revealed that South African women had more hostile and less benevolent attitudes to men than South African men. No such gender gap was present in the case of hostile attitudes in Poland and benevolent attitudes in the United Kingdom. Findings are discussed in terms of Ambivalent Sexism Theory and the countries’ socio-cultural context

Coupled transcriptome and proteome analysis of human lymphotropic tumor viruses: insights on the detection and discovery of viral genes

<p>Abstract</p> <p>Background</p> <p>Kaposi's sarcoma-associated herpesvirus (KSHV) and Epstein-Barr virus (EBV) are related human tumor viruses that cause primary effusion lymphomas (PEL) and Burkitt's lymphomas (BL), respectively. Viral genes expressed in naturally-infected cancer cells contribute to disease pathogenesis; knowing which viral genes are expressed is critical in understanding how these viruses cause cancer. To evaluate the expression of viral genes, we used high-resolution separation and mass spectrometry coupled with custom tiling arrays to align the viral proteomes and transcriptomes of three PEL and two BL cell lines under latent and lytic culture conditions.</p> <p>Results</p> <p>The majority of viral genes were efficiently detected at the transcript and/or protein level on manipulating the viral life cycle. Overall the correlation of expressed viral proteins and transcripts was highly complementary in both validating and providing orthogonal data with latent/lytic viral gene expression. Our approach also identified novel viral genes in both KSHV and EBV, and extends viral genome annotation. Several previously uncharacterized genes were validated at both transcript and protein levels.</p> <p>Conclusions</p> <p>This systems biology approach coupling proteome and transcriptome measurements provides a comprehensive view of viral gene expression that could not have been attained using each methodology independently. Detection of viral proteins in combination with viral transcripts is a potentially powerful method for establishing virus-disease relationships.</p

Gendered Stories of Adaptation and Resistance: A Feminist Multiple Case Study of Immigrant Women

This multiple qualitative case study with eight immigrant women examined women's stories of migration and post-relocation adjustment to the U.S. The results showed that women described their lived experiences in distinctly gendered terms. The four superordinate themes that were present in their stories were Gendered Adaptation, Gendered Resilience, Gendered Violence, and Gendered Discrimination. Implications of these results for counseling practice, research, and advocacy are discussed. © 2013 Springer Science+Business Media New York
