Smoking and vaping are common bad habits, especially among young people. Studying this phenomenon among students is important for developing programs to prevent smoking initiation and help in quitting it. These programs can help improve youth health and reduce the risk of serious illnesses. Purpose: to study the prevalence of smoking traditional cigarettes and electronic cigarettes (including vaping) among 1st-year students of the Ammosov North-Eastern Federal University. The study covered 152 1st-year students of one of the educational departments of the North-Eastern Federal University aged 17 to 30 years (average age 20.62±2.97). A data analysis was performed using the IBM SPSS Statistics software package. A comparison of two groups according to a quantitative indicator with a normal distribution, provided that variances were equal, was performed using Student’s t-test. The share of non-smoking respondents slightly prevailed - 61.8 % (94). The proportion of smokers was 39.2 % (58), of which 35 women (60.34 %), 23 men (39.65 %), the average age of women and men was 20.6 ± 3.03 and 20.65 years, respectively. The smoking experience in men was significantly higher: the average smoking experience in men was 6.48±5.18 years, in women -3.17±2.53 (p=0.002). Thus, men started smoking on average at 14.17±3.96 years, women - at 17.43±3.62 (p=0.002). The smoking index ranged from values close to zero to 7.2 pack/years (mean value - 1.23±1.62 pack/years). The results showed that the majority of respondents noted an increased desire to smoke in a state of stress - 40 (69 %), shortness of breath - 30 (51.7 %), skin problems - 26 (44.8 %), fatigue - 25 (43.1 %), gastrointestinal disorders - 16 (27.6 %), “lump” in the throat - 15 (25.9 %), cough - 22 (37.9 %), frequent headaches 20 (34.5 %), blurred vision - 14 (24.1 %), and attacks of suffocation - 5 (8.6 %). None of the symptoms were noticed in 6 out of 58 (10 %) respondents. The majority of students who combine smoking with vaping do not plan to give up the bad habit (73.07 %), students smoking traditional cigarettes also showed a high percentage of adherence to the bad habit, with 50 % not planning to give up smoking. Thus, this study highlights the need to develop programs to prevent smoking initiation and help to quit among students, which can help improve the health of young people and reduce the risk of serious diseases.

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.

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.

This work is carried out in the laboratory of the Laboratory of mineral processing Institute of Mining of the North and is a continuation of research conducted on a steep-slope concentrator protected by a patent of the Russian Federation. Earlier, on the basis of experimental work carried out on a steeply inclined concentrator, unsatisfactory extraction of the useful component, clogging of the concentrate in the storage chambers, uneven dynamic processes over the entire area of the working surface of the concentrator were revealed. In order to further improve the concentrator, a shut-off valve was installed at the nozzle for water supply throughout the entire volume of the concentrator. Experimental studies have been carried out to improve the efficiency of mineral separation, where special attention is paid to the stability of the dynamic processes occurring throughout the working chamber of the concentrator, the exclusion of the formation of stagnant zones due to flow control and improving the quality of the concentrate as a whole. Thanks to the adjustment of the operating modes of the concentrator by the shut-off valve, it is generally possible to get rid of these negative phenomena and significantly increase the area of the effective working area. The most rational results are determined when the deck of the concentrator 700 is tilted, where the extraction of heavy fraction (magnetite) reaches 91.16 % at a speed of 0.35 l/s. The use of a shut-off valve makes it possible to regulate the flow of water inside the concentrator, at which conditions for effective separation of mineral particles are found. 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 "Yakut Scientific Center of the Siberian Branch of the Russian Academy of Sciences", grant No. 13.
