Construction of rational regimes in motor activity of children aged 3-4 years in pre-school educational institutions of various types
Purpose: to develop rational regimes of physical activity and to determine their influence on the physical condition of children aged 3-4 years attending pre-school institutions of various types. Material: the research was carried out in pre-school educational institutions of various types in the city of Dnepr (Ukraine) (№ 282, combined type, № 192, sanatorium type, № 28, compensatory type, № 244 and № 404, general development). One hundred and eighty-five children took part in the research, 103 of them were 3-year-olds and 82 - preschoolers of 4-year-old age. Control and experimental groups were formed in each age group in kindergartens of a certain type. The control group consisted of 91 children, the experimental group - 94. In the study we used measurements of anthropometry, pulsometry, spirometry, functional tests. The obtained results were processed by independent t-test to evaluate differences between groups. Results: the functional conditions of the children’s study of the experimental groups (boys and girls) have positive changes in the spirometry indices, respiration rates, pulsometry, Ruffier index with a significant difference with the control groups (p<0,05). In addition, in the course of our research, the parameters of the motor activity of children 3-4 years were determined on the base of pacing, while carrying out various organizational forms of physical education. These indicators can be oriented towards the development of a rational motor regimen for younger preschool children. Conclusions: the proposed regimes and forms of motor activity can be used in the organization of physical education of children in pre-school educational institutions of different types for the improvement of morphofunctional indices and physical activity

Экологические аспекты реабилитации переданных в лесной фонд деградированных мелиорированных торфяников
The draining of wetlands, which began in the 1950s, had a significant impact on the ecological situation in Belarus. The result of the intensive use of drained peat lands was the transformation of reclaimed territories into anthropogenically disturbed ones, which led to a deterioration of the ecological and fire hazard situation in these regions. Drained peat lands are systematically transferred to the forestry after agro-industrial use. Thus, in the period from 2008 to 2018 inclusive, 5,995.2 ha of degraded peat lands were transferred to forestry. These territories are abandoned areas overgrown with trees and shrubs, which is one of the causes of fires on the peat lands of the forest stock and leads to large economic losses associated with fire fighting and the death of adjacent tree stands. For the period from 2010 to 2017, peat fires occurred on the area of forest stock on an area of 113.1 hectares. The implementation of a set of environmental measures at the developed peat deposits and degraded peat lands removed from agricultural use helps to reduce the fire hazard of these lands, their restoration and normalization of the ecological situation in the areas of their location.Наиболее существенное влияние на экологическую обстановку Беларуси оказала осушительная мелиорация болот, начавшаяся в 50-х годах ХХ века. В результате интенсивного использования торфяников, мелиорированные территории преобразовались в антропогенно нарушенные земли, что привело к ухудшению экологической и пожароопасной обстановки в данных регионах. После сельскохозяйственного использования и промышленной выработки лесхозам систематически передаются мелиорированные торфяники. Так, в период с 2008 года по 2018 год включительно, лесхозам было передано 5995,2 га деградированных торфяников. Данные территории представляют собой заброшенные участки, заросшие древесно-кустарниковой растительностью, что является одной из причин возникновения пожаров на торфяниках лесного фонда и приводит к большим экономическим потерям, связанным с пожаротушением и гибелью прилегающих древостоев. На территории лесного фонда за период с 2010 по 2017 годы произошло торфяных пожаров на площади 113,1 га. Проведение комплекса экологических мероприятий на выработанных торфяных месторождениях и выбывших из сельскохозяйственного оборота деградировавших торфяных землях способствует снижению пожароопасности этих земель, их реабилитации и нормализации экологической обстановки в районах их расположения

Multi-wavelength observations of blazar AO 0235+164 in the 2008-2009 flaring state
The blazar AO 0235+164 (z = 0.94) has been one of the most active objects observed by Fermi Large Area Telescope (LAT) since its launch in Summer 2008. In addition to the continuous coverage by Fermi, contemporaneous observations were carried out from the radio to γ-ray bands between 2008 September and 2009 February. In this paper, we summarize the rich multi-wavelength data collected during the campaign (including F-GAMMA, GASP-WEBT, Kanata, OVRO, RXTE, SMARTS, Swift, and other instruments), examine the cross-correlation between the light curves measured in the different energy bands, and interpret the resulting spectral energy distributions in the context of well-known blazar emission models. We find that the γ-ray activity is well correlated with a series of near-IR/optical flares, accompanied by an increase in the optical polarization degree. On the other hand, the X-ray light curve shows a distinct 20 day high state of unusually soft spectrum, which does not match the extrapolation of the optical/UV synchrotron spectrum. We tentatively interpret this feature as the bulk Compton emission by cold electrons contained in the jet, which requires an accretion disk corona with an effective covering factor of 19% at a distance of 100 R g. We model the broadband spectra with a leptonic model with external radiation dominated by the infrared emission from the dusty torus. © 2012. The American Astronomical Society. All rights reserved
Insights into the high-energy γ-ray emission of Markarian 501 from extensive multifrequency observations in the Fermi era
We report on the γ-ray activity of the blazar Mrk 501 during the first 480 days of Fermi operation. We find that the average Large Area Telescope (LAT) γ-ray spectrum of Mrk 501 can be well described by a single power-law function with a photon index of 1.78 ± 0.03. While we observe relatively mild flux variations with the Fermi-LAT (within less than a factor of two), we detect remarkable spectral variability where the hardest observed spectral index within the LAT energy range is 1.52 ± 0.14, and the softest one is 2.51 ± 0.20. These unexpected spectral changes do not correlate with the measured flux variations above 0.3 GeV. In this paper, we also present the first results from the 4.5 month long multifrequency campaign (2009 March 15-August 1) on Mrk 501, which included the Very Long Baseline Array (VLBA), Swift, RXTE, MAGIC, and VERITAS, the F-GAMMA, GASP-WEBT, and other collaborations and instruments which provided excellent temporal and energy coverage of the source throughout the entire campaign. The extensive radio to TeV data set from this campaign provides us with the most detailed spectral energy distribution yet collected for this source during its relatively low activity. The average spectral energy distribution of Mrk 501 is well described by the standard one-zone synchrotron self-Compton (SSC) model. In the framework of this model, we find that the dominant emission region is characterized by a size ≲0.1 pc (comparable within a factor of few to the size of the partially resolved VLBA core at 15-43 GHz), and that the total jet power (≃1044 erg s-1) constitutes only a small fraction (∼10-3) of the Eddington luminosity. The energy distribution of the freshly accelerated radiating electrons required to fit the time-averaged data has a broken power-law form in the energy range 0.3 GeV-10 TeV, with spectral indices 2.2 and 2.7 below and above the break energy of 20 GeV. We argue that such a form is consistent with a scenario in which the bulk of the energy dissipation within the dominant emission zone of Mrk 501 is due to relativistic, proton-mediated shocks. We find that the ultrarelativistic electrons and mildly relativistic protons within the blazar zone, if comparable in number, are in approximate energy equipartition, with their energy dominating the jet magnetic field energy by about two orders of magnitude. © 2011.

Analysis of the accumulation the sedimentary mass in coal-water slurries
The problem of assessing the sedimentation stability of water-coal suspensions, which are a promising type of fuel, possessing the advantages of both liquid fuels and coal, which can be effectively used as a substitute for liquid petroleum fuel (fuel oil), is considered. However, coal-water suspensions have not found wide application at present, which is promoted, in particular, by unresolved issues related to their sedimentation stability: in the production, storage, and transport of suspension, an important qualitative characteristic is its stability over time: the higher it is, the more qualitative is the suspension. The paper proposes a method of solving the problem of predicting the value of particle sedimentation during the sedimentation process, which allows us to calculate the dynamics of sediment accumulation over a certain period of time from the beginning of sedimentation at a given depth of dispersion. The implementation of the calculation method as a systematic approach to determining the dynamics of sediment accumulation is shown on the example of sedimentation analysis data of 50 % water-coal suspension from coal from the Neryungri deposit. It is shown that the proposed method of solving the problem of predicting the size of sedimentation of particles during the sedimentation process allows to calculate the dynamics of sediment accumulation for a certain period of time at a given depth, as well as to determine the minimum sedimentation time, at which the particles of maximum size sediment completely
The peculiarities of medical discourse in medical practice of doctor-pathologist
The paper is devoted to the peculiarities of medical pathoanatomical discourseas coherent speech and as linguistic correlate of medical practice taking intoaccount the analysis of its strategies and tactics. The purpose of the paper is to provide a multifaceted analysis of the speech strategies and tactics of pathoanatomical discourse and ways of their implementation. The main strategies of the pathoanatomical variant of medical discourse are anticipating strategy, diagnosing strategy and explaining one. The supporting strategiesare pragmatic, interactive and rhetorical one. The pragmatic strategy is imple-mented through contact establishing tactics, the interactive one – with the help of control tactics, the rhetoric one – with the help of attention correction tactics. The above mentioned tactics and strategies are used in the distinguishing of major, closely interrelated strategies: "contact strategy" (to establish contact with patient’s relatives - phatic replicas of greeting and addressing) and the "strategy of explanation"(used in the practice of pathologist for a detailed explanation of the reasons of patient's death). The ethic aspect of speech conduct of doctor-pathologist is analyzed
