Development of the Educational Process in Physical Education in University: Integrated Approach

В статье применен комплексный подход к анализу реализации рабочих учебных программ в образовательном процессе по физической культуре в Уральском архитектурно-художественном университете. Применены следующие методы исследования: анализ рабочих учебных программ дисциплины «Физическая культура», метод классификации в виде таблиц и включенное наблюдение. Выявлено, что рабочие учебные программы для практических занятий и теоретического курса эффективно дополняют друг друга и способствуют развитию учебного процесса по дисциплине «Физическая культура» в университете.The article applies an integrated approach to the analysis of the implementation of working curricula in the educational process in physical culture at the Ural University of Architecture and Art. The following research methods were applied: analysis of the working curricula of the discipline of physical culture, the method of classification in the form of tables and included observation. As a result of the study, it was revealed that working curricula for practical classes and a theoretical course effectively complement each other and contribute to the development of the educational process in the discipline of physical culture at the university

Влияние транспортно-дорожного комплекса на загрязнение почв и растений тяжелыми металлами

This work aims to analyze heavy metals (HM) in soils and plants of the Balashikha, Moscow region. The authors studied HM content in soil and plant organs of Caragana arborescens and Taraxacum officinale depending on the distance of a motorway. The article shows the relationship between the concentration of HM in the soil and its content in plants. The authors also revealed the peculiarities of accumulation of some heavy metals - cadmium, lead, zinc and copper - in vegetative and generative organs of the studied plants. The authors noted the highest concentration of all heavy metals in dandelion growing near a motorway. According to the share in the total content of the determining elements, the metals can be arranged in the following order: Zn> Pb> Cu> Cd. The authors also observe a different pattern: Zn> Cu> Pb> Cd in soils with less pollution, i.e. in plants located at a 3000 m from the motorway. It has been observed that with a length of 3000 m from the highway compared to the 5 m zone of the road. There is a 1.13 times reduction in lead, 1.74 times reduction in cadmium, 1.89 times reduction in zinc and 1.66 times reduction in copper content in the soil and plants. The analysis shows that the studied plants can be used as bio-indicators of pollution of the biota of large cities. The most hazardous elements are cadmium and lead, which belong to the first hazard class, found in the atmosphere and ecosystems of cities, which is connected with intensive vehicular traffic. On working days, the traffic intensity in the morning hours (08.00-09.00) was 2500 cars and in the evening hours (18.00-19.00) 3000 cars (federal road M7 “Volga”).Целью данной работы явилось проведение сравнительного анализа тяжелых металлов (ТМ) в почвах и растениях г. Балашиха Московской области. Изучено содержание ТМ в почве и органах растений караганы древовидной (Caragana arborescens) и одуванчика лекарственного (Taraxacum officinale) в зависимости от удаленности автомагистрали. Показана связь между концентрацией ТМ в почве и их содержанием в растениях. Выявлены особенности накопления отдельных ТМ – кадмия, свинца, цинка и меди – в вегетативных и генеративных органах исследуемых растений. Наибольшая концентрация всех исследуемых тяжелых металлов отмечена у одуванчика, произрастающего вблизи автомагистрали. По доле в суммарном содержании определяемых элементов металлы можно расположить в следующем порядке: Zn>Pb>Cu>Cd. В растениях, расположенных на расстоянии 3000 м от автомагистрали, т.е. на почвах с меньшей загрязненностью, отмечена уже другая закономерность: Zn>Cu>Pb>Cd. Показано, что с удалением от автомагистрали на 3000 м по сравнению с 5-метровой зоной автодороги в почве и растениях происходит снижение содержания свинца в 1,13 раза, кадмия – в 1,74, цинка – в 1,89 и меди – в 1,66 раза. Проведенный анализ показал, что изучаемые растения можно использовать как биоиндикаторы загрязнения биоты крупных городов. Наиболее опасными элементами являются кадмий и свинец, относящиеся к первому классу опасности, нахождение которых в атмосфере и экосистемах городов связано с интенсивным движением автотранспорта. В рабочие дни интенсивность движения автотранспорта составляла в утренние часы (08.00–09.00) 2500 автомобилей, в вечернее время (18.00–19.00) – 3000 автомобилей (федеральная трасса М 7 «Волга»)

Search for electron antineutrino interactions with the Borexino Counting Test Facility at Gran Sasso

Electron antineutrino interactions above the inverse beta decay energy of protons (E_\bar{\nu}_e>1.8) where looked for with the Borexino Counting Test Facility (CTF). One candidate event survived after rejection of background, which included muon-induced neutrons and random coincidences. An upper limit on the solar $\bar{\nu}_{e}$ flux, assumed having the $^8$B solar neutrino energy spectrum, of 1.1$\times10^{5}$ cm$^{-2}$~s$^{-1}$ (90% C.L.) was set with a 7.8 ton $\times$ year exposure. This upper limit corresponds to a solar neutrino transition probability, $\nu_{e} \to \bar{\nu}_{e}$, of 0.02 (90% C.L.). Predictions for antineutrino detection with Borexino, including geoneutrinos, are discussed on the basis of background measurements performed with the CTF.Comment: 10 pages, 9 figures, 5 table

The Borexino detector at the Laboratori Nazionali del Gran Sasso

Borexino, a large volume detector for low energy neutrino spectroscopy, is currently running underground at the Laboratori Nazionali del Gran Sasso, Italy. The main goal of the experiment is the real-time measurement of sub MeV solar neutrinos, and particularly of the mono energetic (862 keV) Be7 electron capture neutrinos, via neutrino-electron scattering in an ultra-pure liquid scintillator. This paper is mostly devoted to the description of the detector structure, the photomultipliers, the electronics, and the trigger and calibration systems. The real performance of the detector, which always meets, and sometimes exceeds, design expectations, is also shown. Some important aspects of the Borexino project, i.e. the fluid handling plants, the purification techniques and the filling procedures, are not covered in this paper and are, or will be, published elsewhere (see Introduction and Bibliography).Comment: 37 pages, 43 figures, to be submitted to NI
