    The search and study of extended emission-line regions (EELRs) related to AGN in early-type galaxies is interesting to probe the history of nuclear ionization activity and also to understand the process of external gas accretion. In this work, we present observations of the EELR in Mrk 78 obtained at the 6-m Russian telescope using the long-slit and 3D spectroscopy methods. We show that ionized-gas clouds at 12-16 kpc projected distances from the nucleus are ionized by the AGN radiation. Also we have checked if the galaxy appearing in the optical images in the immediate neighbourhood of Mrk 78 near the external clouds is a dwarf companion or a part of a tidal structure. However, the spectrum of this galaxy, SDSS J074240.37+651021.4, obtained at the 6-m telescope corresponds to a distant background galaxy with z = 0.38. © 2020, Astronomical Institute, Slovak Academy of Sciences.Russian Science Foundation, RSF: 17-12-01335Ministry of Science and Higher Education of the Russian FederationAcknowledgements.

    Methodological Approach to Measure the Quality of Life of the Region’s Population

    Full text link
    The article is devoted to the urgent problem of the regional development, i.e. to the development of methodological tools to evaluate the quality of life of the population in the region. The article considers the concept of “quality of life”, and the terms related thereto; and substantiate the author’s position with respect to the concept. The existing domestic and foreign approaches to evaluate the quality of life of the population were analyzed, and the application of the comprehensive approach was reasoned within this study. The criteria for evaluation of the quality of life of the population were distinguished. The authors proposed the methodological approach that considers not only objective indicators of the quality of life presented in the statistical reports of the Russian Federal State Statistics Service, but also employs subjective evaluations of the local population enabling more appropriate evaluation of the quality of life in the region. The methodological tools of the research include mathematical methods of statistical data processing and online survey of the population about the level of satisfaction with various aspects of their life. The methodological tools were tested using the example of the Sverdlovsk Region that is characterized both by the steady improvement of statistical indicators of the quality of life and by low satisfaction of population with certain aspects of the quality of life, which generally decreases the integrated indicator of the quality of life despite positive dynamics of social and economic development of the region and vigorous social policy of the regional authorities. The proposed methodology was used in the evaluation of the quality of life of the Sverdlovsk Region population as part of the development of the Concept of comprehensive regional program “New quality of life of Ural residents” (Decree of the Governor of the Sverdlovsk Region No. 45-UG dated January 29, 2014 “On the Concept of the life quality improvement for the Sverdlovsk Region population before 2030 year — “New quality of life of Ural residents”).The article has been prepared with the support of the grant of the Russian Foundation for Basic Research (RFBR) No. 15-06-09169 “Development of methodical measurement tools and evaluation of the impact of social, economic, medical and demographic factors on mortality rates of working-age population”

    Atherosclerosis (the main cause of a wide range of cardiovascular diseases) and other multifactorial diseases depend on several nutrition factors, defined in general by lifestyle that directly and constantly affects the human body. The modern level of science and technology development is able to form a diet, taking into account all personal characteristics in such a way that makes nutrition an effective preventive measure against diseases in order to keep a person healthy. The purpose of this article is to define and study all the limitations (the scope of its coverage in the scientific literature) that arose in the process of research aimed to formation of an integrated personal approach to designing of nutrition to prevent atherosclerosis. The object of the study was scientific literature, which is available in open source and free access databases: PubMed, ScienceDirect, eLIBRARY.RU, www.fips.ru, Patentscope. The language of search is Russian and English, search depth is 12 years. In the course of the research two food design concepts were found that affect process of digitalization in the food sector: the concept “FoodTech” (food technology) and digital nutritiology. It was established that in Russia only one company — LLC “City Supermarket” (Moscow), that works with the brand “Azbuka Vkusa” — acts in the sphere of “FoodTech” on the Russian market. This company selects personalized food, taking into account the results of personal nutrigenetic tests, in cooperation with LLC “Genotech” (Moscow). There is a need to use biological information, statistical information processing (nutrigenetic studies, nutrigenomic research) and machine-aided data processing (machine learning) for further generation of automatic algorithm that compiles personal recommendations. The relevance of generation of a national domestic database on chemical composition of food products (presented in the market) to simplify the preparation of individual personal diets is observed. We underline the necessity to use the test-organisms, i. e. dorio fish / zebrafish (Danio rerio) and nematodes (Caenorhabditis elegans)), which were used to determine the activity of candidate substances — the biologically active substances that feature antiatherosclerotic properties. In the future the authors plan to conduct a nutrigenomic and nutrigenetic study, using digital achievements. To collect information about consumers, it is necessary to apply digital devices, and use biological informatics to process the results; after that it is necessary to generate the algorithm for automatic selection of personalized dietary recommendations

    The small-angle X-ray scattering (SAXS) technique allows to determine size distributions of inhomogeneities in materials and to predict their properties in Xray optics devices. A number of beryllium materials for the manufacturing of X-ray optics (refractive lenses and speckle suppressors) have been studied by the SAXS.Various composite materials based on porous beryllium have been studied. The effect of adding detonation nanodiamonds to the beryllium matrix on the scattering ability of the material is discussed. Keywords: porous beryllium, SAXS, detonation nanodiamonds, speckle-suppresso

    AbstractThis paper addresses the problem of creating effective educational technologies aimed at developing university students’ professionally-oriented EFL communicative competence in research-oriented higher educational settings. Two techniques (mini-research and individual educational trajectory), being actional components of the educational technology developed, were analyzed from the acmeological potential perspective based on the study undertaken. The study participants were undergraduates and master's students majoring in non-language-related fields

    Studying effects of external conditions of electrochemical measurements on the photoelectrochemical properties of semiconductors: cyclic voltammetry, impedance spectroscopy, and Mott – Schottky method

    Get PDF
    In this paper, the dependences of the semiconductors’ photoelectrochemical properties on the experimental conditions were studied for the solid solution of CdS and ZnS, graphitic carbon nitride, and the platinized carbon nitride. The cyclic voltammograms were obtained under different scan rates. The sample investigations were carried out by two ways, at the constant external voltage and varied amplitudes and at different external voltages and the fixed amplitude. The Mott – Schottky dependences were studied at different frequencies. The basic dependences of the changes in the photoelectrode target characteristics on the experimental condition were found. Some recommendations for the correct comparison of qualitative and quantitative photoelectrochemical data were formulated.https://doi.org/10.15826/elmattech.2023.2.01
