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.

The article presents the results of many years of research in the field of air (dry) method of separation (enrichment) of minerals. The results of a manufactured pneumatic separator of the POS-2000 type, which passed pilot tests in a number of gold ore deposits in Yakutia and the Amur region, are presented. The work presents developments to improve the design and production parameters of the installation, where reduction of weight and size parameters is relevant and in demand at this time, especially for mobile mobile versions of enrichment plants. The article shows laboratory experimental work aimed at a detailed study of the dynamics of the behavior of multiphase media in complex chambers, both in simplified laminar and turbulent cases. For a more detailed study of the influence of different air flow on the process of separating various minerals by density and size, an experimental laboratory installation with three toroidal zones was assembled, consisting of a flexible transparent plastic reinforced pipe, bent in the form of a screw (screw helicoid). The maximum angles of rise of particles along the internal boundary of the laboratory stand, the speed of soaring of particles depending on density and size, the maximum angles of hovering and soaring at different air speeds are considered. Studies have been carried out on the distribution of particles in the radial section in different sections of the pipe (S1-S3), in which angular differences in distribution were obtained due to different levels of the ratio of centrifugal and gravitational forces, at tested speeds and turning radii. Further research aimed at the possibility of modifying the existing pneumatic separator to reduce weight and size and the development of a new type of centrifugal pneumatic separator are shown. 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.

The article provides brief information on the current state of healthcare in the Oymyakonsky ulus of the Republic of Sakha (Yakutia). Based on a survey of 440 respondents, the social conditions of local residents and those who have moved from this district to other settlements of the Russian Federation have been analyzed. The reasons for the migration outflow of the population from Oymyakonskii ulus of Yakutia to other settlements of the Russian Federation were reviewed. It was revealed that 42,8 % of the respondents are planning to move to another district or city, and 32,8 % periodically have a similar intention. The study showed that only 4.1 % of ulus residents are satisfied by the performance of local physicians, whereas among those who have previously left the region this indicator was 47.6 %. This fact is mainly due to the lack of specialized doctors and the high turnover rate due to the lack of housing for visiting specialists, difficult living conditions and harsh climate. According to the respondents, unsatisfaction with the quality of medical care and the desire to give a good education to children are the strongest predictors of the emigration of the local population outside the ulus. It is important to note that the vast majority of those who have left the district do not plan to return. All of the above shows that this problem requires comprehensive government assistance, especially in the field of health care.

The article discusses the skidding concept, types and methods. In addition to specialized skidding tractors (cable skidder, grapple skidder, with a pack grip, and forwarders), modern single-machine complexes for harvesting wood according to Canadian and Scandinavian cutting technologies are presented. A theoretical analysis of tractor skidding performance is carried out, namely: the influence of the average skidding distance and soil conditions is estimated; an assessment of the impact of the type of logging and the taxation characteristics of the stand is given; the influence of soil and terrain conditions is estimated; the impact of the operator's qualifications and working conditions is evaluated. Based on the analysis of literature sources and production experience in the field of logging operations, the expediency of changing the operating mode of operators, as well as the use of special application software packages that allow real-time evaluation of the efficiency of the skidding tractor and its technical condition is justified. The influence of the category of soil conditions and the presence of non-operational areas in the cutting area on the average skidding distance, other conditions being equal, is shown. The work was carried out within the framework of the scientific school "Innovative developments in the field of logging industry and forestry" of the Arctic State Agrotechnological University.
