Simulation model for assessing the risks of accidental oil spills based on cluster

The paper proposes a new risk-oriented approach to the implementation of control and supervision activities in the field of regional environmental control. The issues of building a simulation model of oil spill risks assessment, implemented in the form of a digital mapof the region based on a combination of clustering methods and spatial data analysis are considered. The analysis is based on data on accidents at field oil pipelines in the license areas of Khanty-Mansi Autonomous Okrug for the period from 2014 to 2020. The result of the analysis is a digital mappublished on the Internet with authorized access and reflecting 5 levels of risk for the districts of the study area.

he specifics of posture formation among schoolchildren living in the city of Khanty-Mansiysk against the background of undifferentiated connective tissue dysplasia

Undifferentiated forms of DST are widespread among children living in Khanty-Mansiysk, in connection with which it is relevant to assess the influence of this pathology on the formation of posture in schoolchildren of the North. Determination of the type of posture and the identification of stigmas of dysembryogenesis was carried out in 208 schoolchildren of the city of Khanty-Mansiysk. Posture types were divided into: normal, round, flat and stooped. Participants with the number of stigmas from 0 to 5 were allocated to the comparison group (n = 66), the rest (6 or more) made up the study group (n = 143). A card was entered, including 43 hair dryers. The study found that the incidence of UCTD among children in the Khanty-Mansi Autonomous Okrug-Yugra is noticeably higher than among those living in temperate latitudes and has a negative effect on the formation of posture. Key words: North, posture, physical development, undifferentiated connective tissue dysplasia.

ОСОБЕННОСТИ ЕСТЕСТВЕННОГО ЛЕСОВОЗОБНОВЛЕНИЯ ГАРИ УРАЙСКОГО ЛЕСНИЧЕСТВА ХМАО

Приведены данные исследований естественного лесовозобновления гари в условиях Западно-Сибирского среднетаежного равнинного лесного района таежной лесорастительной зоны (на примере Урайского лесничества, расположенного в юго-западной части Ханты-Мансийского автоном- ного округа – Югры на территории кондинского административного района). Оценка лесовозобновле- ния проведена по методу учетных лент, заложенных на расстоянии 50 и 100 м от стены леса. Данные исследований показали непрерывность лесовосстановительного процесса на гари. Отмечается наличие всходов, самосева и подроста высотных категорий «мелкий», «средний» и «крупный». лесовозобновле- ние гари происходит двумя древесными породами – сосной и березой. По существующим нормативам возобновление сосны оценивается как хорошее. По количеству всходов и подроста преобладает сосна. При удалении от стены леса на 100 м происходит уменьшение количества всходов и подроста всех кате- горий крупности в 2–3 раза в сравнении с аналогичными показателями на расстоянии 50 м от стены леса независимо от вида древесной породы. Во всех высотных категориях отмечается преобладание жизне- способного подроста сосны – до 90–100 %, что является основным показателем успешности лесовос- становления исследуемой гари на данном этапе развития. береза в большинстве случаев представлена сомнительными по жизнеспособности экземплярами. В качестве лесохозяйственных мероприятий мож- но предложить проведение мониторинга за состоянием подроста и уходные мероприятия за подростом. The results of features formations of post-fire pine undergrowth on burnt area of the middle taiga zone of Western Siberia (for example, Uraisk forestry department) in location of the Khanty-Mansi Autonomous Area. Undergrowth was studied on tapes laid out parallel to the forest edges at a distance of 50 and 100. According to studies it is observed of reafforestation continuity of burned areas. The presence of sprouting and undergrowth of the high- elevation categories «small», «medium» and «large» is noted. The burned areas reforestation with two tree species – pine and birch proceed. According to current specification, the pine natural regeneration is assessed as «normal». The amount of pine undergrowth is greater than the amount of birch undergrowth. To be at 100 m from forest edges the number of seedlings and undergrowth decreases by 2–3 times in comparison with the same indicators at 50 m from the forest edges. There is a predominance of vital pine undergrowth – up to 90–100 %. This is evidence of the successful reforestation of burned areas at this stage of development.

Increase in recoverable oil reserves based on system treatments of injection wells

Background. The article considers and justifies the need to take into account the indicators that characterize the amount of balance reserves involved in the development, as well as the increase in recoverable oil reserves due to EOR, when evaluating the technological efficiency of the treatment of the alignment of the pick-up profile (RUNWAY). Aim. If the increase in recoverable reserves is significantly less than production, this will lead to a loss of oil production potential. This fact is of particular importance in the conditions of the arrangement of the old squares and the presence of a developed infrastructure on them. Materials and methods. Materials were used to assess the dynamics and degree of development of oil reserves, calculations of the increase in recoverable reserves. Results. The article presents the results of the accumulated technological efficiency of work to improve oil recovery using various technologies for leveling the intake profile (runway) and non-stationary flooding at the facilities of Subsurface user in Khanty-Mansi Autonomous Area – Yugra on the basis of system-targeted impact on the reservoir. The article also presents materials on the assessment of the dynamics and degree of development of oil reserves, as well as calculations of the increase in recoverable reserves. Conclusions. Calculations based on the assessment of the increase in initial and residual recoverable oil reserves from the implementation of annual EOR programs carried out in accordance with the methodology of PJSC Gazpromneft indicate that the implementation of these programs contributes to additional involvement in the active development of previously poorly drained or non-drained oil reserves.

Genetic Approach to Assessing the Infrastructure Coherence of an Industrial Region

In the context of external shocks, socio-economic coherence of an industrial region reflects its ability to function successfully. Many researchers examine economic space, focusing on interaction between entities (including infrastructure) while ignoring territorial boundaries. However, it is necessary to consider a region’s endogenous core, whose historically connected elements generate evolutionary changes under the influence of external factors. This study develops tools to assess regional infrastructure coherence, taking into account the endogenous determinants of its socio-economic development. The research methodology includes: a comparison of absolute and relative territorial characteristics and infrastructure development parameters; statistical, economic and mathematical methods for determining and evaluating the resulting indicators; an expert assessment of the infrastructure potential; a matrix method for identifying the depth of infrastructure gaps. An analysis of Sverdlovsk oblast and neighbouring regions revealed infrastructure gaps of the first level of depth (insignificant, significant, stably significant), violating the integrity of the regional core, as well as gaps of the second level of depth (forming, potentially forming), requiring serious transformations of the core elements. The con ducted research determined the infrastructure coherence characteristics of the regional core. Thus, the most favourable situation is in Sverdlovsk oblast, whose core has strong integrity. The most unfavourable situation is observed in Perm Krai and Khanty- Mansi Autonomous Okrug. Perm Krai’s core is characterised by minor gaps of the first level of depth and potential second level gaps. In Khanty-Mansi Autonomous Okrug, significant first level gaps are already established, while second level gaps are still forming. This situation occurred due to the industrial specificity of these regions, as well as the discrepancy between high economic activity (increasing the demand for transport services) and infrastructure development. Further research will focus on the ways to improve the regional connectivity at the intra- and inter-regional levels.

Analysis of the episootic situation of cattle leukemia in the Siberian Federal District

The analysis of the epizootic situation of cattle leukemia in the Siberian Federal District as a whole and in individual regions of the district is given. The study was carried out in the Republics of Altai, Tuva and Khakassia, in the Altai and Krasnoyarsk Territories and in five regions: Irkutsk, Kemerovo, Novosibirsk, Omsk and Tomsk. The materials of diagnostic studies obtained by veterinary specialists of the Siberian Federal District for 2017-2019 are presented. This information has been analyzed and summarized both for the Siberian Federal District as a whole and for its individual constituent entities. Studies show the spread of bovine leukemia virus infection in the whole district. A tense epizootic situation with cattle leukemia was noted, since the Siberian Federal District ranks second in Russia in terms of the number of adverse locations (322). However, compared to 2017, the number of adverse locations in 2019 decreased by 57, sick animals - by 977 heads, infected animals - by 70836 heads. The number of adverse locations has decreased slightly, while the number of infected animals in some regions has increased. As of January 1, 2020, no hematologically sick animals were found in the Republics of Altai, Khakassia, Buryatia and Tuva, but the number of animals infected with BLV increased. The experience of individual regions of the country that are free from BLV infection (Sverdlovsk, Vologda, Leningrad, Murmansk, Arkhangelsk, Kostroma, Kirov regions, Khanty-Mansi Autonomous District, etc.) shows that bovine leukemia is an infection that can be controlled. It is possible to eliminate the disease in herds of cattle with any level of BLV infection as a result of carrying out complex health-improving measures, as well as organizational and veterinary-sanitary measures with the obligatory removal of sick and BLV infected animals from the herd.

The political metaphor “Tyumen Matryoshka”: external linguistic image

This article explores the functionality of political metaphor “Tyumen Matryoshka”. The research material contains the mass communication texts of the daily analytical newspaper, which a subsidiary of the “RosBusinessConsulting” media group (https://www.rbc.ru).
