The purpose of the study is to identify the priorities of physical activity, previous experience of classes and motives for attending physical education and health classes in men aged 40-60 who lead a sedentary lifestyle. The objectives of the study are conduct a survey in order to identify the priorities of physical activity, previous experience of classes and motives for attending physical education and health classes in men aged 40-60 who lead a sedentary lifestyle. The hypothesis of the study is as follows: identification of the priorities of physical activity, previous experience of classes and motives for attending sports and recreation classes will determine the starting positions for developing a program of sports and recreation classes with elements of martial arts for men aged 40-60 years who lead a sedentary lifestyle. The research methods are analysis of scientific and methodological literature, questioning, survey, conversations. The results are as follows: the answers received to the proposed seven questions made it possible to identify the initial positions for the development of a program of physical culture and recreation classes with elements of martial arts for men aged 40-60 years who lead a sedentary lifestyle.

This article deals with the rehabilitation of students of the preparatory medical group of the university in physical education classes using folk games and exercises of the indigenous peoples of Yakutia. The aim of this study was to identify the role of games and exercises of the indigenous peoples of Yakutia in promoting the health of students in modern pandemic conditions. The following research methods were used: analysis of literary sources on the topic of scientific work, analysis of specialists in the field of medicine on the studied topic, analysis of the results of the study. To achieve this goal, the following research objectives were set: to study scientific and methodological literature on the topic of research; to investigate the impact of folk games and exercises of the indigenous peoples of Yakutia on the health promotion of students in isolation. The research hypothesis is as follows: the process of raising a healthy lifestyle of students will be effective if national games and exercises are introduced into the educational and educational process. The results of the pedagogical experiment confirmed the effectiveness of the developed technique of physical education of students. Traditional exercises and games of the indigenous peoples of Yakutia contribute to the preservation and improvement of the health and physical fitness of students.

The large amount of peaty soils on the territory of the Russian Federation, especially in the Arctic zone, necessitates the study of their temperature regime and thermophysical properties. The paper presents the results of an experimental study of the thermal conductivity and amount of unfrozen water in sandy soils with varying degrees of peat content. Experiments were carried out on samples with a damaged structure, which were represented by slightly decomposed peat, medium-grained river sand and their various mixtures. It has been established that the degree of peat content affects such physical values as porosity, thermal conductivity and the amount of unfrozen water. For thawed peaty sandy soils, as the degree of peat content increases, the porosity value increases. For both thawed and frozen peaty sand soils, thermal conductivity decreases with increasing degree of peat content. Moreover, the thermal conductivity for frozen soils are higher than for thawed soils. The amount of unfrozen water also depends on the degree of peat in the soil and decreases as it increases. The measured thermophysical properties of peaty sand soil can be used to model the temperature regime in the area of frozen and thawed peat soils.

The article is devoted to the study of the effects of cryogenic treatment on the hydrophobic and hydrophilic properties of clay sands in order to increase the efficiency of their disintegration and enrichment processes. Experiments have shown that cryogenic treatment leads to selective destruction of dispersed formations, where processes occur that precede the process of disintegration, in which the weakest mechanical bonds are broken, and at the same time passivation of surface energy occurs, which is proved by experimental studies to establish the phenomenon of hydrophobization of the surface of finely dispersed mineral particles. The mechanism of this process is due to complex cyclic phenomena of cryogenic treatment, such as crystallization and recrystallization of water in microcracks and pores of dispersed particles. As a result of the cumulative effect, new pores and spaces are formed inside the conglomerates, which, upon subsequent freezing, forms a new ice structure that contributes to the rupture of the conglomerate. An important factor in the efficiency of cryoprocessing is the pre-saturation of samples with water, which gives the disintegration a volumetric character. The research methodology included the use of a new method of direct flotation without collectors, which makes it possible to assess the hydrophobicity of particles. The experiments were carried out on a laboratory flotation machine using a foaming agent to intensify the flotation process. Samples with a certain initial humidity were cryogenically processed using freeze-thaw cycles. The yield of the foam product was studied depending on the number of cycles and the use of the foaming agent. Studies have revealed stable dynamics of the hydrophobization process, with an increase in the disintegration effect from cycle to cycle. Cryogenic treatment, by breaking the bonds between the particles and opening the pores, allows air bubbles to fix on the surface of the particles, enhancing the process of disintegration in the water-air environment. The phenomenon of hydrophobization during cryogenic treatment explains the high disintegration effect of high-clay sands in the water-air environment. The work was carried out within the framework of the state assignment of the Ministry of Science and Higher Education of the Russian Federation (topic No. 0297-2021-0022, Unified state information system for recording the results of research and development work No. 122011800089-2) using the equipment of the Center for Collective Use of the Federal research center ҺYakut Scientific Center of the Siberian Branch of the Russian Academy of Sciencesһ (grant No. 13.TSKP.21.0016).
