Social interaction as a factor of elderly and disabled peoples activity in receiving cardiovascular health services in Russia

The article presents the results of studying the peculiarities of the social interaction and its influence on the social activity of the elderly and disabled people in receiving cardiovascular health services in the Russian Federation. In order to study the level of knowledge about cardiovascular health and the prevention of cardiovascular diseases in February – June, 2018 the sociological research was conducted in Belgorod region (Russia) among elderly and disabled (n=240) by Laboratory of social projects of the Belgorod National Research University. The main research methods were qualitative (content analysis of individual social rehabilitation maps of the elderly and disabled) and quantitative methods (questionnaires

Mathematical model for determination of exhaust concentration dynamics in urban atmosphere under unknown turbulent air flow velocity

The paper proposes the 3-D nonlinear mathematical model for analytic determination of exhaust concentration dynamics in the city regions under the important stipulation that an airflow velocity is not a priory known. To determine an unknown airflow velocity the nonlinear mathematical model is proposed and this nonlinear model is solved by analytical method. In this model it is provided that the turbulent and molecular diffusion coefficient changes depending on the vertical remoteness above the ground surface. The proposed model can be used for solutions of operative problems on urban traffic organization, of long-term planning of urban agglomeration development and new highway building

Time-dependent problem for determination of exhaust concentration in urban transport system

The paper proposes the 3-D mathematical model for analytic determination of exhaust concentration dynamics in the city regions under a priori information on airflow velocity. In this model it is provided that the turbulent and molecular diffusion coefficient changes depending on the vertical remoteness above the ground surface. The numerical example of problem solving is presented. The created model can be used for solutions of operative problems on urban traffic organization, of long-term planning of urban agglomeration development and new highway building

Comparative Evaluation of Lacquer Film Stability Applied to a Surface Fluorination

The characteristics of lacquers for surface fluorination Biflyuorid-12, Ftorlak and Ftor-Lux were evaluated in preclinical conditions during this study. During the evaluation of lacquer film retention stability on the surface of artificially damaged enamel the best performance were shown during the study of Ftor-Lux propertie
