The algorithm of practical realization of technology of correcting disturbances of students' posture during the process of physical education taking into account the level of biogeometric profile

Actuality. One of the consequences of scientific and technological progress is the increase of amount of knowledge and increase of the number of people engaged in mental activity. To the category of people of mental activity also belong students who must work it out in the shortest possible time due to a significant increase in the amount of scientific information. As a consequence, a decrease in the volume of motor activity and appearance of various diseases arise. Of all the diversity of the range of detected diseases among modern students, disturbances of posture is one the most prevailing. Objectives of research: to theoretically substantiate and develop the technology of correction of students' posture with taking into account the state of its biogeometric profile for increasing the efficiency of the process of physical education. Results of research. The substantive components of the algorithm for practical realization of the technology of correction of students' posture disturbances during the process of physical education with taking into account the level of biogeometric profile became: three stages of practical realization during which the corresponding tasks of gradual integration of author technology were solved; - means and methods of practical realization, selection and realizationn of which was carried out according to scientific grounds of effectiveness of their application in the direction of correction of disturbances of posture; - structure and system of organization of conducting practical classes during which practical realization and experimental testing of the developed corrective measures was carried out; - criteria of effectiveness of practical realization which included a list of indicators, according to which both current control and general assessment of testing the technology in practice of physical education of students of higher education establishment was carried out. Conclusions. Based on the results of the confirmatory experiment, we have developed and practically tested the technology of correction of the fixed biogeometric profile of students' posture during the process of physical education. To the content of the author technology the following components were included: purpose, objectives, principles, stages and conditions of its practical realization, tools and methods, current pedagogical control and performance criteria. The results of the confirmatory experiment and the data of the current pedagogical control allowed us to develop 15 complexes of physical exercises of different target orientation. The perspective of further researches lies in development of technology disturbances of musculoskeletal system of students of special medical groups during the process of physical education with taking into account the state of its biogeometric profile

Towards to Extraction of Nanodispersed Noble Metals From Natural Black Graphite Shales

A theoretical approach based on the density functional theory and the pseudopotential method was applied to consider diffusion and accumulation of Au, Pt, and Pd in graphite. It is shown that Pt atoms migrate easily inside graphite. They can stop at structure defects and accumulate there, attracting each other and forming plate clusters. Atoms of gold do not penetrate into graphite but link with edge atoms of broken graphite crystallites, forming three-dimensional metallic particles. Palladium behavior is intermediate between platinum and gold. Addition of silicon into graphite can promote the extraction of noble metals because Si atoms force out Pt, Pd, and Au atoms from their bonded states. Last effect can be used as a mechanism of striking off metals from graphite and their extraction from shale

Disseminated Tumor Cells in Bone Marrow of Gastric Cancer Patients: Correlation with Tumor Hypoxia and Clinical Relevance

Aim. The evaluation of the clinical relevance of disseminated tumor cells (DTCs) in bone marrow (BM) of patients with gastric cancer (GC) and their association with primary tumor hypoxia. Patients and Methods. 89 resected specimens were used. DTCs were detected using immunocytochemistry, the level of tumor hypoxia using NMR spectroscopy, CD68, CD34, VEGF, and VEGFR-1 (Flt-1) expression using immunohistochemistry, and MMP-2 and MMP-9 activity using zymography. Results. DTCs were detected in 51.4% of GC patients with M0. There was significant correlation between frequency of DTCs in BM and level of tumor hypoxia (P<0.024). DTCs presence was accompanied with Flt-1 positivity of BM. The correlation between DTCs and tumor VEGF expression in patients with M0 was shown (P<0.0248). Activity of MMP-2 and MMP-9 in BM was linked with DTCs in patients with M0 (P<0.05). Overall survival (OS) of patients with M0 and DTCs was shorter than that of patients without DTCs (patients in both groups were operated only) (P=0.0497). Conclusion. Appearance of DTCs correlates with hypoxia level in primary tumors. Detection of DTCs in GC patients may be relevant indicator for adjuvant chemotherapy using

Метод прогнозирования числа публикаций на основе интегрального показателя по данным Web of Science и Scopus

The study is completed within the framework of the state order of the Minstryof Education and Science of the Russian Federation “Monitoring and analysis of publication and patent activities in Russian and global science to support the national policy in science and technology” (Project No. 28.12616.2018/12.1). The authors aim at building relevant instruments for assessing and forecasting the total amount of Russian science publication based on the data of two global science citation systems, i. e. Web of Science and Scopus, with de-duplicating by digital object identifier used in both systems. The related tasks are defined: selection of the method to forecast the number of Web of Science indexed articles within the “back forecast” method; development of integral index to calculate the number of publication based on Web of Science and Scopus data; calculation and forecast of the number of articles and publications by G7 and BRICS states up to the year 2021 with scientometric methods based on Web of Science and Scopus data. The authors suggest a conceptually new method to calculate the integral index of publications based on Web of Science and Scopus data to exclude duplication. The total number of academic articles and publications (based on Web of Science and Scopus data) is calculated for the period 2007-2016, and the forecast is provided up to the year 2021.Цель представленного в статье исследования - формирование релевантного инструментария расчёта и прогноза совокупного числа публикаций российских исследователей на основе данных двух глобальных систем научного цитирования - Web of Science и Scopus - с дедубликацией по Цифровым идентификаторам объекта, используемым в обеих системах.

The last Pleistocene glaciations phylogeography episode of Phaneroptera falcata (Poda, 1761) (Orthoptera: Tettigoniidae) in the Volga River basin based on the mtDNA Cytochrome C Oxidase subunit 1 (COI) gene fragment

This study is to research the phylogeography of Phaneroptera falcata (Poda, 1761) in the Volga river basin based on the mtDNA Cytochrome C Oxidase subunit 1 (COI) gene fragment at the last Pleistocene glaciation episode. The studied location is the Volga river basin, a territory within the central and partially southern parts of European Russia; it includes the rivers Volga, Oka, Khoper and Don basins. We used the traditional molecular phylogeography methods: mtDNA COI gene fragment from the key locations within the studied area was sequenced and then analyzed (cladogram topology, haplotype diversity, cladogram calibration etc.). The phylogenetic tree shows the dispersion of our samples over the following regions: Lower Volga, Middle Volga, Lower Oka, Middle Oka, Upper Oka, Don basin, Khoper basin. Nine haplotypes determined from our samples; they are grouped into 7 haplogroups. Six of them are in the basins of the main rivers of the Volga region: three haplogroups - on the Oka (Upper, Middle and Lower Oka respectively), haplogroups of the Khoper and Don basins, and the haplogroup of the Middle Volga combining two subgroups – Lower and Middle Volga basins. The distribution of found haplogroups correlates with big river basins in the Volga area (Volga, Oka, Khoper, Don)

The 2003 edition of the GEISA/IASI spectroscopic database

The content of the current (2003) version, GEISA/IASI-03, of the computer-accessible spectroscopic database, GEISA/IASI, is described. This "system" or database is comprised of three independent spectroscopic archives, which are (a) a database of individual spectral line parameters on 14 molecules, H2O, CO2, O3, N2O, CO, CH4, O2, NO, SO2, NO2, HNO3, OCS, C2H2, N2, and the related 51 isotopomers and isotopologues, representing 702,550 entries, in the spectral range 599-3001 cm-1, (b) a database of spectral absorption cross-sections (6,572,329 entries related to six molecules, CFC-11, CFC-12, CFC-14, HCFC-22, N2O5, CCl4), and a catalogue of microphysical and optical properties (mainly, the refractive indices) of atmospheric aerosols. The modifications and improvements, which have been implemented since the earlier editions of this database, in terms of content and management, have been explained in detail. GEISA/IASI has been created with the specific purpose of assessing the capability of measurement by the IASI instrument within the designated goals of ISSWG in the frame of the CNES/EUMETSAT European Polar System preparation.
