Preservation of student health at university class exercise: implementation technology

The article describes health preservation technology among students at the university class exercise, which includes five technological stages (motivational-stimulating, substantive-procedural, control-adjusting and reflexive). It is proved that the effectiveness of technology use is ensured by the observance of the pedagogical conditions: the saturation of educational process by health saving elements (techniques, means); taking into account the teacher's mental, physical performance and individual characteristics of students; methodological support of the educational process organization; teacher preparedness for health-saving activitie

Physical education department students: year-to-year physical progress tests and analysis

The studies showed the Physical Education Department students’ physical fitness level remaining virtually same throughout the academic period, moreover some progress was noted in some physical fitness components. Knowing that the practical Physical Education training hours in the curriculum tend to fall by the fourth year, we may assume that the main reason for the specific progress is the still high interest and commitment for Physical Education in the student

Benchmarking of the professional education system in postsecondary institutions of the Russian Federation

In this article, the concept "benchmarking of the professional education system" is addressed as the information and management system analysis concerning the activities of the best postsecondary professional institutions (PSPI), and the management methods in the development of professional education system. The research method is benchmarking that allows the authors to determine methods, forms, technologies of educational activities, and management method

Metal acetate based synthesis of small sized Cu2ZnSnS4 nanocrystals effect of injection temperature and synthesis time

We report the colloidal synthesis of small sized Cu2ZnSnS4 CZTS nanocrystals NCs via a hot injection method using zinc and tin acetates in combination with copper acetylacetonate as metal precursors. A systematic investigation of the in amp; 64258;uence of the injection temperature in the range from 190 o C to 300 o C on the size distribution, composition and phase purity of CZTS nanocrystals has been performed. It has been found that temperature plays the key role in changing of the metal sources reactivity and in amp; 64258;uences the amp; 64257;nal composition of the nanocrystals. The mechanism of nanocrystal formation has been investigated by Raman spectroscopy of aliquots of their solutions. It starts from the formation of a Cu2 xS phase as a core followed by the incorporation of Zn2 and Sn4 atoms into its structure regardless of injection temperature

This paper reveals the system of medical and pedagogical support of students' health in the educational process of the Belgorod State National Research University. It is argued that this system includes the target, substantial, operational, and productive components. A special place is given to disclosing the content of the activities of the University Center for a person's functional state correctio

Clinical and epidemiological features of acute intestinal infections in children in Arkhangelsk for 2015-2018

In recent years, there is increasing evidence of the significant role of the intestinal microbiome in the normal functioning of the whole body. The composition of the intestinal microflora affects the human immune system, and its metabolic processes, and even behavior. Therefore, maintaining an optimal balance in the structure of a normal gut microbiome is very important for human health. But the high prevalence of acute intestinal infections(AII) suggests that this balance is very fragile. The diversity of the causes of the All and the greater their specific gravity to determine the practical value of the clinical-epidemiological diagnosis, and was the basis for conducting our study. The aim of our work was to identify clinical and epidemiological features of acute intestinal infections in children of the Arkhangelsk region. We have evaluated the indicators of children's morbidity of acute intestinal infections in the Arkhangelsk region, as well as a retrospective clinical and epidemiological analysis in 143 children who underwent acute intestinal infections in 2015-2018 and hospitalized in the Center for infectious diseases of the Arkhangelsk regional clinical hospital. There is a high proportion of intestinal infections of unknown etiology (55.9%). Viral infections (mainly due to rotavirus gastroenteritis) prevail in the structure of All with established etiology. Among bacterial All met salmonellosis, shigellosis and campylobacteriosis.В последние годы появляется всё больше данных о существенной роли кишечного микробиома в нормальном функционировании всего организма. Состав кишечной микрофлоры влияет и на иммунную систему человека, и на его обменные процессы, и даже на поведение. Поэтому поддержание оптимального баланса в структуре нормального микробиома кишечника очень важно для здоровья человека. Но высокая распространённость острых кишечных инфекций (ОКИ) говорит о том, что баланс этот очень хрупок. Многообразие причин ОКИ и большой их удельный вес определяют практическое значение клинико-эпидемиологической диагностики, все это и явилось основанием для проведения нашего исследования. Целью нашей работы стало выявление клинико-эпидемиологических особенностей острых кишечных инфекций у детей Архангельской области. Нами была проведена оценка показателей детской заболеваемости острыми кишечными инфекциями в Архангельской области, а также ретроспективный клинико-эпидемиологический анализ у 143 детей, перенесших острые кишечные инфекции в 2015-2018 гг. и госпитализированных в Центр инфекционных болезней Архангельской областной клинической больницы. Отмечается высокий удельный вес кишечных инфекций неустановленной этиологии (55,9%). В структуре ОКИ с установленной этиологией превалируют вирусные инфекции (в основном, за счёт ротавирусного гастроэнтерита). Среди бактериальных ОКИ встречались сальмонеллёз, дизентерия и кампилобактериоз

Radiative emission from Cu2ZnSnS4/ZnSn core/shell nanocrystals

Kesterite Cu2ZnSnS4 (CZTS) nanocrystals so far have been found to luminesce neither at room temperature nor at low temperature. Here a core-shell architecture for kesterite CZTS nanocrystals is demonstrated by applying a ZnSn-alloy shell overcoating approach. These CZTS/ZnSn nanocrystals show luminescence emission at 1.05 eV, which is red-shifted by about 0.4 eV from the absorption onset and is attributed to a radiative transition involving a deep defect. Temperature-dependent photoluminescence measurements within a range of 20-200 K indicate the presence of a competing nonradiative channel with an activation energy of 50-60 meV
