    The influence of surface oxide layers on the kinetics of hydrogen emission at the high vacuum of 10 to the minus 8th power torr was investigated at temperatures from 20 to 450 C using samples of pure AB00 aluminum and the cast alloy AMg. Cast and deformed samples of AMts alloy were used to study the effect of oxide film thickness on the rate of hydrogen emission. Thermodynamic calculations of the reactions of the generation and dissociation of aluminum oxide show that degasification at elevated temperatures (up to 600 C) and high vacuum will not reduce the thickness of artificially-generated surface oxide layers on aluminum and its alloys

    Regional population expenditure for foodstuffs in the Russian Federation: componential and cluster analyses

    Full text link
    The article describes the solving of the problem of conducting the component and cluster analyses of population expenditure on food as one of the most important components of the standard of living. The purpose of the analysis is to develop the regional clusters of the Russian Federation, which vary in the structure of household expenditure for foodstuffs. The foodstuffs are presented in absolute units taking into integral account the standard of living index. The methods of intellectual analysis such as component and cluster analyses are applied as the research methods. The procedure for the data intellectual analysis based on the interconnected performance of component and cluster analyses is proposed. The procedure of the data intellectual analysis considers the interrelation between the results received by different methods, and also the possibility to return to the previous method for the purpose of repeating the analysis to specify consistently the clusters composition. Few clusters of the wealthy regions characterized by the high and average levels of expenditure for foodstuffs are revealed as well as the quite many clusters of not enough wealthy and not wealthy regions characterized by the low level of expenditure for foodstuffs. It is shown that the growth of standard of living characterized by the size of a gross regional product per capita is followed by the growth of the Gini coefficient, which indicates both the inequality of income distribution and reduction in expenditure for low-value foodstuffs. The results of the analysis can be applied to the development of the decision-making support system intended for the analysis of the scenarios of macroeconomic regulation in the eld of income policy for the purpose of increasing the standard of living of population. The analysis of the population expenditure for foodstuffs has allowed to reveal the cluster structure of the regions of the Russian Federation, to show it according to the generalized indications, to formulate the specific characteristics of the clusters of the regions and important management decisions

    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”

    Spin-transfer mechanism of ferromagnetism in polymerized fullerenes: AbinitioAb initio calculations

    Full text link
    A mechanism of the high temperature ferromagnetism in polymerized fullerenes is suggested. It is assumed that some of the C60_{60} molecules in the crystal become magnetically active due to spin and charge transfer from the paramagnetic impurities (atoms or groups), such as hydrogen, fluorine, hydroxyl group OH, amino group NH2_2, or methyl group CH3_3, dispersed in the fullerene matrix. The exchange interaction between the spins localized on the magnetically active fullerenes is evaluated using \textit{ab initio} calculations. The nearest neighbour and next nearest neighbour exchange interaction is found to be in the range 0.1÷0.30.1\div 0.3 eV, that is, high enough to account for the room temperature ferromagnetism.Comment: typos corrected, 8 pages, 3 figures, LaTe

    Development of professional tolerance in medical students through professionally-oriented foreign language training

    Get PDF
    Global sociocultural transformations in the modern world are associated with expansive digitalisation and its impact on human life. Given the advantages of digital technology development, a number of significant problems arise, in particular, social differentiation, commercialisation of socionomic professions, information consumerism, emotional estrangement due to the virtualisation of communication, a shift in value orientations, replacement of traditional moral norms with their destructive simulacra. There is a clear need for intensification of educational activities in higher education focused on the humanisation of public consciousness, the promotion of social cohesion and the development of the moral backbone of an individual. Hence, it is necessary to refer to the theoretical and methodological foundations of tolerance development in students. The aim of this article is to clarify the concept of professional tolerance of a doctor and describe the strategy of its development in students in the process of foreign language training. Considering the issue of professional education of future doctors, the authors note that the vector of students’ spiritual and moral development is determined by the values, attitudes, and norms of medical ethics and deontology. Herewith, the principle of tolerance is of the basic ones since professional medical practice is based on regular interpersonal interaction. The authors define the concept of a doctor’s professional tolerance as the willingness to provide patients with high-quality medical care regardless of the heterogeneity of socio-cultural factors and subjective personal aspects. This concept assumes the doctor’s tact, empathy, psychological flexibility and poise. The proposed strategy for the development of professional medical tolerance in students via professionally-oriented foreign language training involves the holistic formation of its cognitive, affective and conative components through the educational content and the parity in subject-subject interaction. In the development of the cognitive component, considerable importance is ascribed to supplementing the basic educational materials by authentic content of social and professional orientation. The connecting link of the development of cognitive and affective components is the identification and levelling of stereotypes and prejudices regarding socially significant diseases. The basis for the development of the affective component is pedagogical tolerance, a favourable educational environment, interactive activities at classes, and the facilitation of students’ reflection. The development of the conative component of tolerance is directly tied to the development of professional communicative competence of future doctors: the study and development of various speech clichés in the format of interaction with patients; revision of politeness formulas; practicing non-verbal communication means in playing out quasi-professional situations; mastering the speech norms “plain language” and “people-first language”
