Regular practice of breathing exercises helps to improve the quality of breathing, increase pulmonary ventilation, improve tissue oxygenation and accelerate the removal of carbon dioxide. This contributes to a more efficient supply of oxygen to organs and tissues, which is especially important during physical training. Hypoxic training, which is carried out in conditions of reduced oxygen content, also has a positive effect on the body. As a result, the body's endurance increases, the aerobic power index and overall physical fitness improve. Thus, the use of various methods of influencing the body through the respiratory system allows you to increase the effectiveness of training loads and achieve higher sports results. The purpose of this article is to evaluate the effect of breathing exercises on the level of lactic acid in the body. The objectives are to identify the effectiveness of breathing exercises aimed at restoring the body after physical activity by measuring the level of lactic acid in capillary blood. Methods of analysis of breathing exercises, medical and biological methods were used. The result of the study showed that the level of lactate is associated with the effect of breathing exercises on blood circulation and oxygen saturation of body cells.

The article aims to study the influence of the Olympiad activities on the quality of acquiring general professional competencies in students of the department "Pediatrics" of the Medical Institute of North-Eastern Federal University. The objectives are to compose tasks, analyze the results of the Olympiad, and make recommendations on how to improve the conduct of the Olympiad. To achieve the objectives, an analysis of the compiled tasks and the results of the Olympiad for three years was carried out. The authors used the method of comparative analysis. The hypothesis was confirmed that the Olympiad activity significantly increases the motivation for acquiring general professional competencies, which will be the basis for the future professional activity of a doctor. In the conditions of higher professional education, the integration relationship between the humanities and natural disciplines is of particular attention; this is the relevance of this study. The analysis of the results of the Olympiad and the results of academic performance in the disciplines "Latin with the basics of medical terminology" and "Pathophysiology" showed that every year the Olympiad is gaining popularity: the number of participants is growing, the methods of organizing and conducting are being improved, and the tasks of the Olympiad are being revised. The organizers of the Olympiad noted the improvement in the results of the Olympiad. Despite the decrease in the number of winners of the Olympiad, there is an increase in the average score from 37.8 to 43 (out of the maximum 50 points). This is due to the increase in the average score of the participants in the second round from 20 to 26 points. Every year the increase in the number of participants leads to increased competition for prizes. Taking into account the results of the study, measures were recommended to improve the quality of the Olympiad.

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).

For the effective enrichment of gold-containing concentrates and heavy concentrate with a high content of magnetic minerals, a beneficiation method in a jigging machine with a magnetic system has been proposed in the laboratory of the Laboratory mineral processing of the Institute of Mining of the North SB RAS. In the proposed method, a combination of gravitational enrichment and magnetic separation is carried out in a jigging machine. The most important factor in the process of effective extraction of gold from concentrate enrichment products containing iron scrap and minerals with high magnetic susceptibility in a jigging machine is the constant loosening of the forming natural bed. Subsequently, the method was improved and an electric pulse source was developed to create a pole-alternating magnetic field, which makes it possible to ensure a loosened state of the bed. A physical and mathematical model has been developed based on a Fokker - Planck type equation to determine the probability of particles passing through the thickness of a bed under the condition of the required state of loosening. Approbation of the model shows that the obtained calculations correlate with the results of experiments on a jigger with an electromagnetic installation under the conditions of the jiggering process: jigger cycle frequency 210 min-1, bed height 80 mm, amplitude 6 mm and pulse duration of the pole-alternating magnetic field from 0,1 sec. 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).

The study is aimed at solving the urgent problem of stabilizing the temperature regime of construction sites and operation of engineering structures in the permafrost zone of the Republic of Sakha (Yakutia) and a changing climate. The currently used method of soil cooling using seasonally operating cooling devices, despite its effectiveness, requires a long exposure time and significantly delays construction time, which in some cases is unacceptable. In order to evaluate the effectiveness and prospects of the technology of rapid soil freezing using solid carbon dioxide (dry ice) for cooling permafrost soils, a full-scale experiment was carried out. To conduct the experiment, a test site was equipped at one of the construction sites in Yakutsk with the installation of cooling and thermometric wells. During the experiment, the temperature field of the soil and the temperature inside the cooling well were recorded. As a result of the experiments, actual data were obtained on the distribution of temperature in the soil depending on the temperature and distance from the cooling well during the cooling effect and after it. The results obtained provide grounds for assessing the tested technology as promising in the conditions of permafrost soils in Yakutia.

The results of experimental studies to identify changes in the aerodynamic properties of particles of a malleable useful component (gold) during the disintegration process on a fundamentally new laboratory two-stage cone impact mill are presented. Lead markers of various configurations, as well as random particles of ore gold, act as gold simulators. This mill is designed specifically for the chain of dry concentration devices. The mill includes two zones of destruction of geomaterials. The upper elongated cone-shaped zone formed between the working rotor and the inner surface of the installation housing. Due to the narrowing of the space between the working surfaces, close contact of ore particles is created with each other and with the working bodies. In the lower sequential zone, in the zone of free movement of particles by rolling along the surface of the external working rotor, intensive forging of lamellar particles of the useful component of the ore occurs by the flow of pelitic ore material formed during the destruction process in the upper zone of the mill. In the process of conducting laboratory research on the particles of the useful component, a close analogy was discovered in the properties of their behavior in an aerodynamic and liquid environment. The soaring speed (SV) of gold particles less than 2 mm, with the same physical parameters, as well as their hydraulic size (HF), depends only on the thickness. At the same time, in the mill during the grinding process, the particles of ore gold undergo thickening of the edges. Processed particles of lead markers and gold retain their physical weight, and their degree of extraction by dry enrichment increases by 1.5-2 times due to isometrization of forms. 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 of the unified state information system for recording research, development and technological work for civil purposes 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.
