This article presents the results of studying the course of tuberculosis infection in children and adolescents who have suffered COVID-19 according to a study of ELISA with the presence of Ig G in the blood. The follow-up included 54 patients aged 2 to 16 years with local forms of tuberculosis who were treated in the inpatient conditions of the children’s department of the E.N. Andreev Scientific and Practical Center of Phthisiology from 2020 to 2022. The patients were divided into two groups: the first group – children who had suffered from COVID-19 according to the results of IgG in the blood – 17 patients; the second group – those who had not had COVID-19 with negative results in IgG blood – 37 patients. A comparative medical and social analysis revealed that children who had had COVID-19 had both social and medical risk factors, as well as a burdened epidemiological history, contact with adult patients with acute progressive and destructive forms of pulmonary tuberculosis. Methods of detecting the tuberculosis process in the first group, 88 % of children were detected by contact, 6 % by treatment, 6 % by immunodiagnostics; in the second group, 51 % by contact, 8 % by treatment and 41 % by immunodiagnostics of the patients. In the study of the tuberculosis process in children of the first group, the infiltration phase was recorded in 80 % patients in the reverse development phase: resorption– 10 % and in the calcification phase – 10 %. In the second group, the infiltration phase was in 50 % of children, the resorption phase was in 14 %, and the calcification phase was in 36 % of patients. It should be noted that the effect of a previously transmitted new coronavirus infection on the course and outcomes of the tuberculosis process was not revealed, no correction of chemotherapy was required, and there was no need to increase the duration of treatment.

The evaluation of heat input through fences is an important part of the task of predicting the summer thermal regime of a building under a transparent dome, the interest in the construction of which in the northern regions has increased recently. The calculation of the summer thermal regime of a building under a dome is complicated by taking into account the greenhouse effect, which requires solving the problem of radiative heat transfer in the system: opaque wall - semitransparent screen - environment. It is also necessary to take into account the convection in the dome space. А relatively simple model for calculating the characteristics of heat transfer through the wall of a building with a dome, which takes into account the greenhouse effect, is considered in this paper. Comparison of calculations with experimental data allows us to speak about the adequacy of the proposed model. It is shown that the presence of semitransparent screen due to the greenhouse effect leads to a significant raise in temperature under the dome and an increase in heat input into the building. The influence of ventilation in the dome space on heat access through the enclosing structure for the selected values of external parameters: external temperature and solar radiation was evaluated. The proposed model of heat transfer through the enclosing structure with a semitransparent screen can become part of a more complete model for calculating the thermal regime of a building under a dome.

A spatial analysis of intra-regional transport accessibility of settlements in the Arctic districts of the Sakha Republic (Yakutia) by GIS is an urgent task and can become a necessary support for the processes of decision-making and planning of sustainable development of these territories. The purpose of the study is to perform a spatial analysis of intra- regional transport accessibility of settlements in remote Arctic regions of Yakutia on the example of Anabarsky and Nizhnekolymsky districts. On the basis of the GIS network analysis and calculated coe cients of density of the transport network, the assessment of transport accessibility of the study areas according to winter and summer scenarios was carried out. The automobile and river networks were built on the basis of data from open cartographic sources: OpenStreetMaps and Google Earth Engine, the atlas of highways of the Sakha Republic (Yakutia). On the basis of satellite images of Landsat 5, 8 and Sentinel 2, non- o cial (informal) roads that play an important role in communications between settlements were decrypted and digitized. QGIS and ArcGIS programs were used to perform network analysis and build a map of time availability of the settlements using isochronous method. The created maps clearly show the availability of settlements by time interval. The conducted research made it possible to determine that remote sensing and geoinformation systems are key tools for a spatial analysis of transport infrastructure. Using this tools, it is possible to conduct network analysis of various levels of complexity, as well as build graphs of the transport network, greatly simplifying the counting procedure. The paper tested a method that allows to identify uno cial roads in the Arctic, and the presented methods of GIS analysis and modeling that can be used for further deeper network analytics and graph theory to improve the methodology for studying the transport accessibility of the Republic of Sakha (Yakutia).

The results of generalization and GIS integration of the results of the study of all known indigenous deposits and manifestations of diamonds located in the distributed and undistributed fund of the subsoil of the Russian Federation are presented. The work takes into account the results of prospecting, exploration and exploitation works, minutes of meetings of regional (TKZ) and federal (RKZ and GKZ) commissions on mineral reserves and published data. As a result, a GIS-integrated database was created containing 1,319 objects, for each of which key parameters were determined: coordinates, shape, size, age, average diamond content, forecast resources, and diamond reserves. It was established that the indigenous diamond deposits are concentrated in the Central Siberian subprovincia and account for 2.3 % of all known kimberlite bodies, diamond-bearing kimberlite bodies in the Yakut diamond-bearing province - 282, the predominant body shape is a pipe (59 %). There is no correlation between the size of kimberlite bodies and their diamond content, small pipes, as well as large diatremes, can be industrially diamondiferous, the prevailing absolute age of industrially diamondiferous kimberlites is 329-382 million years.

The article presents the results of the study by various geologists of the geological structure and prospects of ore-bearing trog complexes performing structures such as throgs, which were identi ed at di erent stages of geological research in the western part of theAldan-Stanovy shield. The main types of traction complexes and their sections were determined. The nature of the occurrence of sedimentary (terrigenous), volcanogenic- sedimentary and metavolcanic rocks performing throgs and forming throg complexes was established. The nature of the ratio of these rocks in the context of the trog complex in the studied trogs was described. The results of the study of trog complexes showed that they are generally characterized by facies variability, heterogeneity of metamorphism and dynamothermal processing of rocks (especially in the sides of trogs) with the formation of mylonites and cataclasites. It was established that the throgs are con ned to three regional systems of discontinuous disturbances. Both consonantal and secant discontinuities were marked inside the throgs, de ning their block tectonics. The results of determining the geological age of the rocks of the trogovoi complex were presented. The trog structures are characterized by ore mineralization associated with the processes of sedimentation (ferruginous quartzites, copper sandstones) and volcanogenic ore formation (copper-crusted and polymetallic mineralization), as well as with the processes of metamorphogenic-hydrothermal redistribution of ore matter (stratiform scheelite mineralization, ore-bearing quartz veins). It was also found that the metallogeny of the trog structures has not been studied su ciently. Nevertheless, the majority of geologists who studied the trogovye complexes noted in their reports that Precambrian trogovye complexes can be considered as important and metallogenically promising geological objects in the western part of the Aldan-Stanovy Shield and deserve more in-depth study.

A complex comparative study of diamonds from commercially productive diatremes of Daldyn- Alakitsky eld (Udachnaya, Zarnitsa) determined mineral typomorphic features, which allows diagnosing dispersion haloes of kimberlite material in sedimentary thick layers. By the set of typomorphic features, diamonds from Udachnaya pipe have many common features with crystals of other deposits of Daldyn-Alakitsky diamondiferous region. Increased content of variety II and III cubes, close by their features to diamonds from deep inclusions of eclogites, may be referred as inherent only to the Udachnaya pipe features. Zarnitsa pipe demonstarted pronounced prevalence of rhombic dodecahedral habit crystals of variety 1 with large concentration (> 30 %) of typically rounded diamonds. On the whole, diamonds of Daldyn eld are characterized by a complex of typomorphic features, which allow distinguishing them from diatremes of other diamondiferous regions of the Siberian platform with con dence.

Tick-borne encephalitis (TBE) is a natural focal viral infection that occurs with high fever and intoxication. It is characterized by damage to the gray matter of the brain and/or the membranes of the brain and spinal cord, with the development of meningitis, meningoencephalitis or encephalomyelitis. The disease can result in persistent neurological and psychiatric conditions, and even death. The carriers of tick-borne encephalitis are ixodid taiga ticks. This type of tick is especially proactive in the spring and summer, endangering adults and children. Infectioning of a person occurs after a tick bite. The causative agent of tick-borne encephalitis is a neurotropic, RNA-containing virus. Tick-borne encephalitis is characterized by increasing neurological symptoms. The symptoms after an encephalitis tick attack are very varied. There are 5 main forms of tick-borne encephalitis: febrile, meningeal, meningoencephalitic (occurs in 15 % of the country as a whole, and twice as often in the Russian Far East). To diagnose with tick-borne encephalitis, it is necessary to take into account clinical manifestations (damage to the central nervous system), epidemiological data (time of the year, presence of vaccination, fact of a tick bite) and laboratory methods of specific diagnosis. The Republic of Sakha (Yakutia) is not an endemic region for the spread of TBE. However, in recent years due to climate change, the number of ticks and bites in this area has increased. This article describes a case of TBE in a 6-year-old child. The disease was extremely severe and resulted in death. Despite the fact that TBE is an extremely rare pathology in our republic, screening for this pathology must be carried out during the tick season.

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.

This article contains data on the nature and level of study of the territories in which the north-eastern part of the Sakha Republic is located, which are potentially oil and gas bearing. In 1979-1992, seismic exploration of oil and gas was carried out in the Tastakh trough, the Zyryanka depression by JSC Yakutskgeofizika. The section of the Tastakh trough includes strata of terrigenous rocks of lithological unconstrained composition. Its capacity is 2.5-4.5 kilometers. The paper describes reflecting horizons based on Neogene-Quaternary, Jurassic-Cretaceous deposits. In addition, during the research, it was found that the Lower Cretaceous sediments present in the Tompon depression are divided by the Tomporuk-Kitchan zone of thrust divisions of the Late Cretaceous stage of activation of the Verkhoyano-Kolyma region. Upper Jurassic volcanogenic sedimentary rocks, Lower Cretaceous coal-bearing deposits are contained in the Zyryanka depression at 6 and 5 thousand meters, respectively. This article contains an opportunity for the allocation of time intervals, interpretation of sedimentary synchronous complexes of deflections, depressions, shelf. Seismic materials in these territories have a quality that can be recycled. The evidence of the need for this procedure appears during discussions on the topic of geological development, the structure of the mountain-folded Verkhoyano-Kolyma region, as well as the shelf that adjoins it. These data are confirmation of the presence of oil and gas in these territories. The work was carried out with the scientific 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 under grant No. 13.TsKP.21.0016. Support was received in the form of funds under the State Assignment from the Ministry of Science and Higher Education of the Russian Federation No. 122011100158-1.

The northern slope of the Yakut uplift covers the North Aldan oil and gas bearing region and partially the Pre-Verkhoyansk and Vilyui oil and gas bearing regions. The potential oil and gas content of the Northern slope of the Yakut uplift is associated with a wide stratigraphic range of promising sediment complexes (Vendian-Cambrian, Permian-Triassic and Jurassic-Cretaceous). All these complexes have confirmed oil or gas occurrences of varying intensity. Terrigenous-carbonate formations of the Vendian-Cambrian complex are the most promising deposits in terms of oil and gas potential, confined to the lower part of the upper sub-suite of the Yudom formation of the Vendian. A relatively effective fluid seals for the Vendian hydrocarbons can be the variegated formation of the Lower Cambrian, composed of dense mudded-off carbonate rocks. The prospects of Permian-Triassic and Jurassic-Cretaceous sediment complexes will be determined by the absence or presence of zonal and local fluid seals, including non-traditional permafrost hydrate. Thus, several oil and gas complexes of different origin and with different types of fluid seals are identified in the section. A brief overview of the promising oil and gas complexes of the Northern slope of the Yakut uplift emphasizes the need for priority geological exploration for oil and gas. Clarification of geological structure of the studied area will make it possible to identify the most promising zones and sites for planning and organzing exploration work. The work was carried out with financial support within the framework of the State Assignment of the Ministry of Science and Higher Education of the Russian Federation No. 122011100158-1 using scientific 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" within the framework of grant No. 13.TsKP.21.0016.
