Opisthorchiasis-related topical issues

The article analyzes statistical data on the 2020 vs 2019 opisthorchiasis incidence rate on the territory of the Russian Federation and in foreign countries, provides absolute and intensive morbidity indicators across entire the Russian Federation and specifically in its subjects — republics and regions, general prevalence of helminthiasis, and opisthorchiasis particularly overall pattern of parasitic diseases, as well as contribution of opisthorchiasis to general pattern of biohelminthiasis, its dynamics, and prevalence of relevant causative agent. A comparative analysis for incidence rates in the regions where opisthorchiasis was recorded and mean country-wide statistical parameters was carried out. As a result, it was concluded that despite a decline in the Russia-wide overall parasitic morbidity, an excess of mean indicators, sometimes significant, was noted in some regions. Thus, compared to Russia-wide magnitude of intensive indicator, it was higher by 4-fold in the Komi Republic, whereas in the Kurgan, Vologda, Arkhangelsk Regions and the Nenets Autonomous Okrug — by 3-fold. The article provides an analysis of the population age groups as well as percentage of opisthorchis-affected urban and rural populations. In addition, the special clinical and epidemiological significance of opisthorchiasis remains urgent due to severity of its course, affected various body systems and organs, emergence of serious complications leading to disability, and in some cases to fatal outcomes, the presence of natural foci, most of which are located in the Russian Federation. Almost all territories adjacent to the basins of the Ob, Irtysh, Tom rivers and their tributaries pose special concern regarding opisthorchiasis. The data related to prevalence of helminthiasis larvae detected in fish in 2020 and 2019 since 2010 are presented. Based on the data shown above, strict adherence to preventive measures plays an important role in reducing opisthorchiasis incidence rate and preventing its spread.

Assessment of the influence of climatic factors on the state of terrestrial ecosystems in the Northwestern region of Russia

The article analyzes the change of climatic conditions in the Northwest of Russia, including the characteristics of dangerous hydrometeorological events (cold and heat waves, strong winds, extreme rainfall, snowfall, ice-frost deposits, hail) and slow climatic changes (increase in the number of days with the transition of air temperature through 0°С, coastal abrasion) in connection with their negative impact on terrestrial ecosystems. It was found that the influence of meteorological and climatic factors on terrestrial ecosystems is most pronounced in the northern part of the studied region, especially on the coast of the Barents Sea. Towards the south, the values of all indicators gradually decrease, and their structure changes. In the northern part of the study area (Murmansk and Arkhangelsk oblasts, the Nenets Autonomous Okrug), phenomena associated with strong winds and intensive ice-frost deposition, which contribute to the formation of an ice crust on the Earth’s surface, prevail. As one moves away from the coast, severe frost is observed more often (Komi Republic). In the center and south of the region, heavy rainfall, severe frost, and intense heat are the most frequent, resulting in a high fire hazard. The study carried out the ranking of the subjects of the Northwestern Federal District according to the degree of intensity of this process. Comprehensive assessments of the negative impact of changing climatic conditions on terrestrial ecosystems can be used to make decisions on the development of a strategy for environmental security of the regions of the Russian Federation.

Identifi cation of Adhesives for Repairing Ancient Ceramics: The Case of the Neolithic and Chalcolithic of Far Northeast Europe

This study focuses on the composition of the adhesives used to repair clay vessels, and on the technique of their preparation in the Late Neolithic and Chalcolithic (late 4th to early 3rd millennia BC) sites of Far Northeast Europe (the Republic of Komi and the Nenets Autonomous Okrug). Remains of adhesives were detected on 70 of 171 repaired pots. To date, five samples of ceramics from dwellings of the Chuzhyael culture have been analyzed. Gas chromatography-mass spectrometry revealed no markers of coniferous trees or bitumen; but did reveal markers of birch, suggesting that fractures and cracks on broken pots were plastered with birch tar. The composition of organic compounds in samples indicates the use of two vessels in the technological process: in one of them, birch bark was subjected to pyrolysis, while the other was a receptacle for tar. This comparatively complex technology reveals one more specialization in the domestic manufacture of the taiga hunter-gatherers, including the use of special furnaces. Analytic procedures employed by us open up new prospects for the study of the material culture of Far Northeast Europe, extend our knowledge of domestic manufacture, and offer new material for AMS dating.

Classification of vegetation of the Barents Sea coast at the mouth of the Indiga River

Classification of coastal vegetation from the standpoint of the ecological-phytocoenotic approach at the estuary of the Indiga River, flowing into the southeastern part of the Barents Sea, is presented. On the base of 131 relevés of coastal vegetation, 23 associations in 18 formations were identified. The coastal vegetation in different biotopes differs in the structure and features of the phytocoenoses floristic composition. Based on the signs of vegetation cover, mesorelief, and hydrological features of the shores, the following biotopes were identified: saline and brackish marshes, beaches and dunes, tidal flats at the mouths of estuaries, saline and brackish lagoon lakes on marshes. The marches with 14 described associations have the highest phytocoenotic diversity. A phytocoenotic diversity of the beaches is noticeably less, 4 associations are described there. The vegetation background of the beaches is formed by the communities of the Leymeta arenarii formation, the vegetation background of the salty marshes is formed by the communities of the Cariceta subspathaceae, Cariceta glareosae, and Cariceta mackenziei formations. In saline lakes, large areas are occupied by communities of the Hippurideta tetraphyllae formation, and the communities of the Triglochineta maritimi and Plantagineta subpolaris formations are rare, the northern limit of their range runs approximately along the Indiga mouth. The vegetation of brackish marshes is mainly formed by the Cariceta salinae herbosum, Junceta gerardii, and Cariceta rariflorae communities. At the mouth of Indiga estuary, large areas are occupied by communities of the Magnocariceta formation. In the mouth of the Indiga, a little north of the range limit, communities of Eleocharis uniglumis, a rare species in the Nenets Autonomous Okrug, are described for the first time at the rank of association Eleocharitetum uniglumis. The aquatic vegetation of desalinated lagoon lakes is represented by the Myriophylleta sibirici formation. The halophyte vegetation of the Indiga River estuary is compared with the estuaries of the rivers of the Kanin Peninsula and the Pechora Bay. The ordination of geobotanical relevés shows a greater similarity of the coastal vegetation of the Indiga estuary with the estuaries of the rivers flowing on the Kanin Peninsula of the White and Barents Seas basins and with the vegetation of the rivers estuaries of the Pechora Bay coast. The article has an electronic appendix (https://journals.rcsi.science/0006-8136/issue/archive).

Оценка жизнестойкости сельских сообществ Ненецкого автономного округа

The concept of resilience is applied to complex social systems to describe the ability of a territory (or settlement) or local community to recover from external shocks. In this context, resilience complements the concept of sustainable development by revealing the mechanisms that enable systems to regenerate during crises. In recent decades, various approaches for assessing urban resilience, including that of Arctic cities in high-risk zones, have been developed in scientific literature. However, a comprehensive methodology for assessing the resilience of Arctic rural communities has not yet been fully developed or tested. The goal of this article is to assess the resilience of several rural communities in the Nenets Autonomous Okrug (NAO), followed by their comparison and classification. Drawing on Russian researchers' experience in measuring the resilience of Arctic cities, the authors propose their own methodology for assessing the resilience of Arctic rural communities. This methodology involves measuring 11 resilience indicators, which are aggregated into a comprehensive resilience index (R-index). The R-index enables the ranking of Arctic rural communities by their resilience levels. In the course of the study, all surveyed rural communities were classified into four groups based on R-index values: 1) isolated communities with low resilience; 2) vulnerable communities prone to external shocks; 3) administrative centers of rural municipalities with moderate resilience; 4) large and stable rural communities. The primary differentiating factors among these communities include geographical location, transport links and logistics, the structure of local economies, and demographic resources. Overall, Arctic rural communities exhibit a high level of social capital. The novelty of this study lies in its application of the community resilience concept to Arctic rural areas, contributing to a deeper understanding of the factors that shape their development potential. Future research should expand the geographical scope of the study and conduct larger surveys to improve the accuracy and reliability of rural community resilience assessments.

Analysis of the influence of living conditions, as a collection of social factors within the environment, on mortality rates among the rural and urban populations of the Nenets autonomous okrug from 2000 to 2019

BACKGROUND: Currently, in the Arctic zone of the Russian Federation (AZRF), there are evident indications of a deterioration in the medical and demographic situation amidst a lack of adequate social infrastructure development. For the first time, we attempted to analyze the impact of living conditions, which encompass various social factors within the habitat, shaped by the social infrastructure, on the mortality rates of the population of one of the regions within AZRF. AIM: To assess the impact of living conditions, as a set of social factors within the environment, on the mortality rates among the rural and urban populations of the Nenets autonomous okrug (NAO) in the period from 2000 to 2019. MATERIALS AND METHODS: The databases “Housing and communal services and social infrastructure in NAO in 2000-2019” and “Death cases in NAO in 2000–2019” including information on the population number and age and gender structure of the NAO population across individual settlements have been collected. Using the scoring system for assessing living conditions, a ranking with subsequent division into tertiles of all rural NAO settlements was carried out according to the value of the integral index of living conditions (IILC). A comparative analysis (tertiles with the city, and tertiles with each other) of average annual age-standardized rates of overall mortality, mortality from the main causes and structural components of external causes (EC) of mortality was performed. Relative risks were calculated as the ratio of mortality rates in each tertile to the corresponding indicator for the urban population. RESULTS: Average annual standardized rates and relative risks of mortality (total, EC, drowning, freezing, alcohol poisoning and transport accidents) of the NAO population demonstrated a “step by step” increase in the sequence “city — highest tertile — middle tertile — lowest tertile”, i.e. as living conditions worsen and as the IILC decreases. Statistically significant differences were identified between the city and tertiles, as well as between the highest (“favorable” living conditions) and lowest (“unfavorable” living conditions) tertiles in terms of total mortality, mortality from EC, drowning and freezing. Mortality rates from alcohol poisoning and transport accidents also increased as living conditions worsened, although the associations did reach the level of statistical significance. With the exception of suicides, the relative risks of mortality for individual EC reached maximum values in the lowest tertile of living conditions. CONCLUSION: Statistically significant inverse associations between total mortality, mortality from external causes and its main structural components, and the values of the integral index of living conditions have been identified among the rural population of NAO. A decrease in living conditions was significantly associated with an increase in mortality rates and relative risks.

THE STATE OF THE ARCTIC PROBLEMS OF THE NENETS AUTONOMOUS OKRUG AND PROSPECTS OF THEIR SOLUTION

The article analyses the first stage of the Nenets Autonomous Okrug’s (NAO) implementation of the 7 tasks set out in the Strategy for Developing the Russian Arctic Zone and Ensuring National Security until 2035. Particular attention is paid to the study of the development of the project for the construction of the deep-water seaport of Indiga and the Sosnogorsk – Indiga railway, transport infrastructure development, including the reconstruction of the seaport and airports. The article analyses the activities on dredging on the Pechora River, construction of a highway, the development of oil and gas condensate mineral resource centers, based on the NAO fields, including the development of new ones. The problem of geological study and development of mineral resource base of solid minerals is considered. The article examines the population dynamics, the experience of Arctic residents, and their tax benefits. The author separately considers the construction of an agroindustrial park and the implementation of export-oriented projects involving deep processing of venison, as well as the issues of developing a tourism cluster in the region. It is concluded that, with the exception of the completion of the Naryan-Mar – Usinsk highway and the intensive development of tourism, the rest of the Arctic projects are at the initial stage, their development hampered by the lack or complete absence of funding.

Distribution of 137Cs specific activity in river sediments of the Barents Sea basin (Nenets Autonomous Okrug, Russian Arctic).

This article focuses on the study of the distribution of 137Cs in the bottom sediments of Arctic rivers of the Barents Sea basin (using the example of the Nenets Autonomous Okrug, Russian Arctic). This research is relevant due to the poorly studied region and the significant number of radiation-hazardous facilities in the Arctic zone of Russia, both those currently in operation and those that are "nuclear heritage sites". The study of 137Cs specific activity in bottom sediments was carried out in the period from 2020 to 2023 in the rivers Chizha, Nes, Vizhas, Oma, Pechora (river delta), as well as the rivers Kolva and Usa (first and second order tributaries, respectively, of the Pechora River). A total of 199 samples were collected. In addition to 137Cs specific activity, the samples were analysed for sediment particle size distribution, organic matter content, carbonate content and ash content. The 137Cs specific activity mainly ranged from the minimum detectable specific activity to 5.4 ± 0.8Bq·kg-1. In the Nes River basin (Kaninskaya tundra), the 137Cs content in bottom sediments reached 36.0 ± 3.2Bq·kg-1 (in the case of lake sediments) and 22.9 ± 3.7Bq·kg-1 (in the case of river sediments), values that are higher than those of the North-West of Russia. Considering the large area of the study area (Kaninskaya tundra, Pechora river delta, southern part of Bolshezemelskaya tundra) and the similarity of physical and chemical parameters of the studied rivers, it is possible to assume the existence of a zone of increased radionuclide content in the Nes river basin. This may be due to the runoff from the Nes River catchment area, its hydrological features, and the accumulation of 137Cs in the small fractions of bottom sediments. The results confirm the conclusions of previous soil studies in the Nes river basin. The main sources of elevated 137Cs content are global atmospheric deposition and the Chernobyl Nuclear Power Plant accident.

Associations between caries experience and oral fluid mineral content among patients in Arctic Russia: a study in the Nenets Autonomous Area

The relationship between the intensity of caries and mineral composition of oral fluid in adolescents in the Arctic zone of Russia was investigated using the example of the Nenets Autonomous Okrug. This study included 171 healthy boys and girls aged 15–17 years. The intensity of caries was assessed using the index caries + fillings + extracted permanent teeth and its components. Unstimulated oral fluid was collected into sterile tubes. Sodium, potassium, magnesium, phosphorus, and total and ionized calcium content and pH were examined in the oral fluid. Considering the pronounced right-sided asymmetry of the components of the index caries + fillings + extracted permanent teeth, calculations were performed using Poisson regression models. Results were presented as relative risks with 95% confidence intervals and as tests for trend. The prevalence of caries in the sample population did not differ by sex and was 87.8% for boys and 93.3% for girls (p = 0.221). On average, 1.8 carious teeth per person were detected in boys and 1.4 in girls (p = 0.021). No differences were found in the number of filled (p = 0.167) and extracted (p = 0.981) teeth. Additionally, the total sodium content in oral fluid was directly proportional to the index of caries + fillings + extracted permanent teeth (p = 0.040) and number of carious teeth (p 0.001). The total oral fluid calcium was significantly associated with both the caries + fillings + extracted permanent teeth index (p = 0.019) and number of filled teeth (p = 0.001). Inverse relationships were found between the number of filled teeth and magnesium (p = 0.028) and phosphorus (p = 0.037) content. The study showed the presence of statistically significant relationships between the mineral composition of oral fluid and index of caries + fillings + extracted permanent teeth and its components. Thus, unfavorable living conditions in the Arctic zone provide additional risk factors for the occurrence of dental diseases. The results of the study, if confirmed in other populations, can be used to develop models for predicting the development and progression of caries in adolescents of the Far North. Further studies of the mineral composition of oral fluid are required to obtain more complete clinical and laboratory data, considering confounding factors such as nutrition and type of filling material.

Особенности правового статуса территорий Арктической зоны, Крайнего Севера, ЗАТО в материалах судебной практики

The article uses the example of the practice of the courts of the Arkhangelsk Region and the Nenets Autonomous Okrug to consider the specifics of judicial disputes involving municipalities in the territories of the Arctic Zone and the Far North, closed administrative-territorial entities.

Fur and leather products in the system of cultural values of the North peoples

Fur and leather products are regarded as the most significant type of household and artistic crafts in the traditional culture of Nenets and Khants, reflecting the relationship between the natural and cultural environment. The article is based on materials from the author's expeditions to the Nenets Autonomous Okrug and the Yamalo-Nenets Autonomous Okrug.

Implementation of the biomonitoring system in large scientific expeditions on the example of the scientific and educational project "Arctic Floating University"

Currently, biomonitoring research is actively developing in the Arctic region, despite this, groups of people who temporarily come to the Arctic remain outside the national monitoring system, unlike the local population. Participation in expeditions on ships implies special living conditions, such as limited space, sensory deprivation. The study aims to analyse the biochemical parameters of blood, the content of essential, toxic elements, persistent organic pollutants (POPs) and vitamin D in samples of the expedition group temporarily coming to work in extreme Arctic conditions. Scientists carried out a study on board the Mikhail Somov scientific expedition vessel as part of the Arctic Floating University project. The participants were 50 people: 26 men and 24 women aged 20 to 72 years. As a result of the analysis, the authors have determined: 8 biochemical blood parameters, vitamin D levels by high-performance liquid chromatography with tandem mass spectrometric detection, the content of essential (Co, Mn, Se, Cu, Zn), toxic elements (As, Cd, Hg, Pb) using an inductively coupled plasma mass spectrometer and POPs by gas chromatography-mass spectrometry. Almost 90% of the expedition participants had vitamin D concentrations below 20 ng/ml, which indicates a deficiency of this vitamin in the body. After conducting a comparative analysis between the expedition group and the permanent population of the Nenets Autonomous Okrug (NAO), it was found that the expedition group significantly reduced the content of not only toxic compounds (As, Cd, Hg, Pb, POPs), but also essential elements (Co, Mn, Se, Cu, Zn), according to compared to the local population. It is worth noting that the concentration of arsenic in the expedition group is 65 times lower (0.12 µg/L) than in permanent residents of the Arctic zone of the Russian Federation (7.29 µg/L), and the concentration of lead in the group of expedition workers was 42 times lower (0.30 µg/L) than in the local population (15.21 µg/L). The data obtained provide information about the elementary and toxic status of the urban population of the Russian Federation. One of the reasons for such differences may be the predominantly traditional lifestyle of the local NAO population and the biomagnification of toxic substances in food chains. If biomonitoring studies are carried out by specialists on an ongoing basis and the data obtained is accumulated, then a basis may appear for predicting risks of both a short-term and long-term nature. The conducted research contributes to the expansion of the biomonitoring system at the national level.

Comparative Analysis of Regional Socioeconomic Heterogeneous Indicators in the Subjects of the Arctic Zone of the Russian Federation and Their Integral Assessment

The Arctic Zone of Russian Federation (AZRF) is a unique geography with diverse socioeconomic factors playing significant roles in its stability and progress. In order to accurately assess and evaluate the overall socioeconomic progress of AZRF, the heterogeneous factors should be considered in an integrated manner, which will give a holistic view of the socioeconomic stability and development of the region. The available literature on socioeconomic development of Russian Arctic region however suffers from lack of integrated analysis of heterogeneous indicators. In this article, the authors have selected five heterogeneous indicators which best describe the socioeconomic condition of a given region, which in this case is AZRF and performed integral analysis for the time period 2014–2019. The indicators refer to socioeconomic aspects such as gross regional product and amount of investments received by the region, which in turn leads to changes in employment opportunities and income level of the population along with social benefits available to them. The mathematical instrument used for the analysis is the theory of fuzzy logic in the framework of determination of the subdirect image of a fuzzy set. This method is scalable and can be extended to any number of indicators of diverse nature since the final score will be in the range of [0, 1] making comparison of regions and ranking possible. Using this method, the subjects were ranked at individual indicator level and at holistic level as a result of which the advantages and disadvantages of each subject and the AZRF as a whole were determined. At holistic level, the subjects were ranked as Krasnayarsky Krai, Arkhangelsk Oblast, Republic of Komi, Murmansk Oblast, Yamalo-Nenets Autonomous Okrug, Karelia Republic, Sakha Republic (Yakutia), Nenets Autonomous Okrug and Chukotka Autonomous Okrug based on the integral scores obtained.

Российская Арктика-2035: полимасштабный прогноз

The subject of the study is the forecast of the development of the Arctic territories of Russia at the zonal, regional and municipal levels based on the concept of technical and economic (structural) dynamics of N. Kondratiev – S. Glazyev – С. Peres. The object of study is the Arctic zone of the Russian Federation. The purpose of the study is to describe the technical and economic dynamics of the Arctic territories until 2035. This goal determined the solution of three tasks: 1) identifying the features of new resource development of the Russian Arctic based on the mineral resources and fuel and energy potential of the Arctic territories of Russia; 2) justification of the current situation in the regions of the Russian Arctic, such as the dynamics of technological structures and calculated positions on the volume of GRP in 2035; 3) compiling a list of Arctic municipalities (49) with limited delivery times for cargo and their typology based on the speed of technical and economic dynamics. Results of the study: I. The resource potential of the Russian Arctic from the point of view of technological structures can be strengthened through the commissioning of deposits of graphite, antimony, and bauxite, the global demand for which is characterized by favorable conditions in the forecast period; II. The regions of the Russian Arctic are differentiated based on the analysis of greenfield projects carried out during the forecast period into three groups of technological renewal: a) maximum; b) partial; c) minimal. The forecast of the GRP of the Arctic territories based on resource production indicators in 2035 determined their rank: 1) Yamal-Nenets Autonomous Okrug; 2) Murmansk region; 3-4) Nenets Autonomous Okrug and the Arctic of the Krasnoyarsk Territory; 5) Arctic of the Republic of Sakha (Yakutia); 6) Arctic of the Komi Republic; 7) Chukotka Autonomous Okrug; 8) Arctic of the Arkhangelsk region; 9) Arctic of the Republic of Karelia. III. Arctic municipalities with limited delivery times are separated into four groups from the point of view of the prospects for the formation of a new technological structure based on new projects: 1) maximum potential (12); 2) average potential (9); 3) without new mining projects, but with prospects for completing the development of previously started ones and technological modernization of old projects (12); 4) without prospects for the deployment of new projects for the development of non-renewable resources, but with prospects for the development of biological resources (16). Possible application of the results can be documents of strategic planning of the Russian Arctic at the zonal, regional and municipal levels.

Staffing of the hematology service of the Russian Federation

Introduction. As part of the implementation of the federal project Development of a network of national medical research centers and the introduction of innovative medical technologies, one of the activities of the National Medical Research Center for Hematology (Center) is the analysis of the staffi ng of medical organizations (MO) of the constituent entities of the Russian Federation (RF) by hematologists.Aim — to analyze the dynamics of staffi ng by hematologists of MO in the RF.Materials and methods. Data from the Federal State Statistics Service (Rosstat) — Federal Statistical Observation Form No. 30 “Information about a medical organization” of the constituent entities of the Russian Federation for 2012–2020, reference books of the Central Research Institute of Organization and Informatization Health of the Russian Ministry of Health in the Russian Federation, information obtained from the results of on-site events of the National Medical Research Center for Hematology, including expert assessments were used.Results. The hematological service is organized in all subjects of the RF, with the exception of the Chukotka and Nenets Autonomous Okrug, Republic of Kalmykia and Altai, as well as the Jewish Autonomous Region. As of December 31, 2021, 1,594 hematologists work in the constituent entities of the RF, of which 460 specialists are in outpatient care and 1133 specialists in hospital settings. Analysis of the availability of full-time positions of hematologists per 10,000 populations in the Russian Federation in dynamics for 2012–2020 revealed fl uctuations in the values of this indicator from 0.06 to 0.17. The largest “failure” in the provision of hematologists occurred in 2014 in almost all federal districts (FD) of the Russian Federation. Only the Urals FD maintains the stability of the indicator of availability of these specialists. Over the past 3 years, there has been an increase in the number of full-time positions of hematologists, while the staffi ng of individuals reduced due to the lack (increase) of new employees and slightly offset by an increase in the coeffi cient of internal part-time work. Thus, the highest combination coeffi cient was noted in 2020 in the Ural (1.49) and Siberian (1.45) FD, the lowest in the North-Western FD (1.09). In accordance with the legal act regulating the activities of the hematology service, the standard for calculating the positions of outpatient hematologists is 1 doctor per 200 thousand of the population, however, the provision of full-time positions for the outpatient stage of care remains not achieved (2021 — 0.92 per 200 thousand); at least 731 doctors are needed against the existing 456 specialists. The staffi ng standard of the department of hematology corresponds to one medical position per 10 beds. Compliance with regulations regarding the formation of the staffi ng table of the inpatient unit was noted in 95% of the constituent entities of the Russian Federation.Conclusion. The issues of personnel shortage of hematologists are relevant. The shortage of hematologists in the Russian Federation indicates the lack of attractiveness of remuneration and indicates the need for management decisions to be made by the Government of the Russian Federation and executive authorities of the constituent entities of the Russian Federation aimed at developing mechanisms for maintaining the human resource of hematologists in the healthcare system.

Трансформация модели развития северного оленеводства в Ненецком автономном округе

The era of accelerating globalization and urbanization has necessitated adaptations in Arctic economic systems. Among the key factors are the active industrial development of Arctic regions, social and cultural shifts among the indigenous peoples of the North, and changes in the modern market. The reindeer husbandry sector developed against the backdrop of collectivization in the 1930s and market reforms in the 1990s. This study aims to analyze shifts in the economic model of contemporary reindeer husbandry in the Nenets Autonomous Okrug (NAO) within the context of global transformations. The research novelty lies in examining the evolutionary transition of reindeer herding farms to a new management system during the Soviet period and investigating the factors influencing its effectiveness. While management improvements resulted in a profound restructuring of the mindset of reindeer herders, the onset of political reforms resulted in the shift to market relations and the upheaval of the industry during the crisis-ridden years of perestroika. The ensuing decline stemmed from the disintegration of the economic system and the government's not being ready to search for the right economic reforms. By employing the principal component method, the study identified two primary factors impacting the unstable nature of meat production: the number of reindeer per herder and the proportion of adult female reindeer in the herd. In farms facing challenges such as understaffing, low morale, or a high percentage of inexperienced workers, caution should be exercised in adopting advanced techniques. This involves adjusting the reindeer load per herder, managing larger herds, and increasing the number of adult female reindeer in the herd. An individual approach and an analysis of previous years' work are crucial to prevent negative trends in production indicators such as the number of calves, adult livestock preservation, and unforeseen loss prevention. Promising directions for future research include an analysis of the effectiveness of support programs for reindeer herding farms, encompassing both subsidies and trainings for young professionals in the industry.

Prevalence of vector-borne diseases among reindeer (<i>Rangifer tarandus</i>) Bolshezemelskaya and Malozemelskaya tundr

The purpose of the research is to establish the prevalence of vector-borne diseases in reindeer (Rangifer tarandus) Bolshezemelskaya and Malozemelskaya tundra.Materials and methods. The research was carried out in 2022–2023 on domesticated reindeer living in the Bolshezemelskaya and Malozemelskaya tundra of the Nenets Autonomous Okrug and the Komi Republic. Stabilized blood was obtained from animals by random sampling and PCR studies were performed for the presence of genetic material of pathogens of the genera Anaplasma, Babesia and Theileria.Results and discussion. The DNA of the causative agent of anaplasmosis was isolated from 14.3% of reindeer from Malozemelskaya (family-tribal community «Vy Tu» (VTU) and «Opseda» (OPS)) and 30.6% of Bolshezemelskaya tundra (Аgricultural production cooperative «Harp» (HARP) and Collective Farm «Izhemsky olenevod and Co» (IZHM)). To a greater extent, vazhenki and calves were infected with anaplasmosis, to a lesser extent – choirs. Genetic material of Babesia pathogens was found in 53.1% of VTU and OPS deer and 36.7% of HARP and IZHM, while babesiosis was most often observed in the chorus group. Teileriosis was found in 10.2% and 4.1% of animal samples among the herds of the Malozemelskaya and Bolshezemelskaya tundra, respectively. The genetic material of the causative agent of teileriosis was isolated mainly from the blood obtained from calves. The causative agent of theileriosis was not found in the biological material of the choirs. The presence of DNA Anaplasma spp. and Babesia spp. in one sample, the proportion of deer from Malozemelskaya tundra herds was 2.4%, from Bolshezemelskaya – 26.5%. The combined course of babesiosis and teileriosis was found to be 8.2% only in VTU and OPS deer. Thus, studies have shown that vector-borne diseases is widespread among the reindeer of the studied farms of the Bolshezemelskaya and Malozemelskaya tundra.

Activity Concentrations of Cs-137, Sr-90, Am-241, Pu-238, and Pu-239+240 and an Assessment of Pollution Sources Based on Isotopic Ratio Calculations and the HYSPLIT Model in Tundra Landscapes (Subarctic Zone of Russia)

The paper is devoted to the assessment of the content of anthropogenic radionuclides in tundra landscapes of the subarctic zone of Russia. The authors of the article studied the features of accumulation and migration of anthropogenic radionuclides and identified probable sources of their entry into environmental objects. Peat samples were collected on the territory of the Kaninskaya Tundra of the Nenets Autonomous Okrug (Northwest Russia). A total of 46 samples were taken. The following parameters were determined in each peat sample: (1) activity and pollution density of anthropogenic radionuclides; (2) isotopic ratios of anthropogenic radionuclides; (3) activity ratios of each radionuclide for layers 10–20 cm and 0–10 cm. The results of the studies showed that the pollution density of the Nes River basin with the radionuclides Cs-137 and Sr-90 is up to 4.85 × 103 Bq×m−2 and 1.88 × 103 Bq×m−2, respectively, which is 2–5 times higher than the available data for the Kanin tundra, as well as for Russia and the world as a whole. The data obtained for Am-241, Pu-238, and Pu-239+240 showed insignificant activity of these radionuclides and generally correspond to the values for other tundra areas in Russia and the world. It was found that some tundra areas (“peat lowlands”) are characterized by increased radionuclide content due to the process of accumulation and migration along the vertical profile. Calculations of isotope ratios Sr-90/Cs-137, Pu-238/Pu-239+240, Pu-239+240/Cs-137, Am-241/Pu-239+240 and air mass trajectories based on the HYSPLIT model showed that the main sources of anthropogenic radionuclide contamination are global atmospheric fallout and the Chernobyl accident.

Personnel training for the forestry complex of the northwestern and Arctic regions of Russia

Introduction. Forestry industry development and management in the North-West and the Arctic zone of the Russian Federation is a national priority, focused on the global competitiveness of the Russian timber industry products. The study aimed to analyze personnel training for forestry, offered by the education system of the North-West and the Arctic zone of Russia, in order to bring the qualities of the graduates of higher and secondary vocational education in line with the needs of the forestry industry in this macro-region. Materials and Methods. The research materials were statistical data from 4 forms of state federal reporting for 2021-2022: on admissions and graduations from the higher education system; graduation from the secondary vocational education system; number of employees of organizations by type of economic activity; demand of organizations by type of economic activity. The methods of descriptive statistics, mathematical modeling and comparative data analysis were used. Research Results. The study determined a list of 20 areas and disciplines of higher and secondary vocational education organizations training qualified personnel for the forestry complex, and formed a group of 19 types of economic activities related to the five main areas of forestry complex work. The scope of annual additional personnel demand of enterprises and organizations of the forestry complex of the Arctic and North-West Russia was calculated with the help of macroeconomic methodology for assessing the economy's demand for qualified personnel. The annual demand for personnel with higher education was 3.54%, for mid-level specialists it reached 4.49%, and for skilled workers and employees – 5.41% of the total number of employees with the appropriate level of education working in the forestry industry. The comparative analysis identified entities where personnel demands could be met by graduates from their region and entities needing additional sources, including graduates from other regions. Discussion and Conclusion. Pronounced lack of own personnel with higher education for enterprises and organizations of the forestry complex was identified in Leningrad Oblast, Chukotka, Nenets and YamaloNenets Autonomous Okrugs. Mid-level specialists currently graduate in sufficient numbers, with the exception of the Nenets Autonomous Okrug. In the next two to three years, a significant shortage of qualified workers and employees (more than 90%) is expected in all subjects of the macroregion. A solution to this problem may be targeted training of specialists in other regions, as well as in regions that are well-known educational centers (for example, Tomsk, Yekaterinburg, Novosibirsk).

Где в Арктике лучшие условия для реализации мер региональной промышленной политики?

This article addresses the research question concerning the assessment of current prerequisites for implementing industrial policy within the Arctic territories of Russia through the efforts of local and regional authorities. The research goal required solving methodological problems, including how to evaluate these prerequisites, analytical problems encompassing individual and integrated scoring, and practical problems such as the differentiation of Arctic territories into responsive,neutral, or conservative regarding regional industrial policy measures. The study is based on regional and municipal statistical indicators, legal documents outlining industrial policy within Arctic regions, and data from the monthly monitoring of the Arctic conducted by the Institute of Regional Consulting. To perform an integrated assessment of the conditions, we employed 17 indicators grouped into five categories: 1) material factors (four indicators reflecting the volume and weight of the industrial sector in the regional economy); 2) spatial factors (four indicators assessing the degree of dispersion or concentration of regional industry locations); 3) technological factors (three indicators measuring the Arctic territory's readiness for the fifth Kondratieff wave); 4) institutional factors (three indicators evaluating the involvement of key actors in industrial activities, the effectiveness of industrial partnerships, and the presence of established regional industrial policy institutions); 5) natural resource factors (three indicators offering a qualitative assessment of the region's key resource assets). Upon integrating individual scores for five categories, which were derived as the arithmetic mean of normalized scores, four distinct groups of regions were identified. The first group, represented by the Yamalo-Nenets Autonomous Okrug (YNAO) and the Krasnoyarsk Arctic, has the most favorable conditions for the deployment of new industrial policy measures. The second group, consisting of the well-established industrial region of Murmansk and the Arctic territories of the Arkhangelsk region, has relatively favorable conditions. The third group, comprising the Nenets Autonomous Okrug, the Chukotka Autonomous Okrug, and the Arctic territories of the Komi Republic, is characterized by less favorable conditions. The fourth group, which includes the Arctic territories of the Republic of Sakha (Yakutia) and the Republic of Karelia, ranks as the least favorable in terms of implementing regional industrial policy measures.
