Development of Manufacturing Process for High-Chromium Steel Large Welding Roll

Due to the operating conditions of weld and calibrating rolls used in the production processes of large electric-welded pipes, their material is subject to stringent wear and abrasion resistance requirements at high temperatures. The limited capabilities of conventional Cr-Mn-Ni tool steels and open die forging technologies with heat treatment processes do not provide the required performance properties for large welded rolls. Therefore, the material of the product was replaced with Cr12MoV high-chromium steel. This required identifying the formation patterns of the fine grain structure of high-chromium steel in order to adjust the production technology with adaptation to the unique conditions and equipment (12.5 MN hydraulic forging press, heating and thermal furnaces) of the forging shop. The technology was offered, which included the development of modes from heating to heat treatment with intermediate two-stage forging from Cr12MoV steel ingots in two sets of combined dies. At the first stage, deformation with a low reduction ratio ε = 5% and a relative feed rate of 0.4 per pass was provided to break and refine the carbide mesh, and at the second stage, intense deformation with a reduction ratio ε = 15% was performed. Further practical application has shown that the durability of weld rolls made from the new material increases by 20–30%.

Interaction of landslide spatial patterns and river canyon landforms: Insights into the Three Parallel Rivers Area, southeastern Tibetan Plateau

The interaction and mechanism of landslide spatial patterns and river canyon landforms are significant for understanding geomorphic evolution in intensive tectonic alpine environments. This study focuses on the Three Parallel Rivers Area (TPRA) in the southeastern Tibetan Plateau encompassing three parallel rivers (the Nujiang, Lancang, and Jinsha Rivers), to examine the synergistic evolution of geomorphic features and landslides. The analysis revealed a pattern of landslide aggregation in the river valley characterized by the sequence Nujiang > Lancang > Jinsha Rivers. This pattern aligns closely with the distribution of geomorphic indices (local relief, surface erosion index, and threshold slope gradient) in the valleys. As local relief, normalized surface erosion index and normalized threshold slope gradient increase, the mean values of normalized landslide area density (NLAD) rise from around 0.11 to 0.39, 0.16 to 0.48, and 0.10 to 0.21, respectively. Concurrently, the mean values of normalized frequency of landslide dams (NFLD) increase from around 0.05 to 0.24, 0.12 to 0.22, and 0.02 to 0.17, respectively. Additionally, knickpoints could induce upstream suppression and downstream promotion of landslides showcasing the feedback of landslides on the valley landscape. Our findings indicate that the landform formation process in the southeastern Tibetan Plateau orogen is intricately linked to a substantial landsliding response and the observed mass movements vividly mirror the landform formation pattern. These results hold potential implications for understanding the dynamic equilibrium between uplift and surface erosion in the region. This study enhances our understanding of the interaction and mechanisms of landslides and valley landforms.

The formation pattern, causes, and governance of network public opinion on university emergencies.

University emergencies, garnering significant public attention and shaping network opinions, pose a crucial challenge to universities' management and societal stability. Hence, network public opinion on university emergencies is a vital issue. Nevertheless, the underlying mechanism has not been fully explored and cannot be efficiently controlled. This study aimed to explore the formation pattern of network public opinion on university emergencies, analyze its causes, and provide scientific governance strategies for coping with this issue. Based on a sample set of 204 cases from the Zhiwei Data Sharing Platform, this study classifies network public opinion on university emergencies into six types and visually analyzes their characteristics: time distribution, subject, duration, and emotion. By integrating the theory of the network public opinion field, this study develops a network public opinion field model of university emergencies to reveal its formation pattern. Furthermore, it analyzes the causes of network public opinion on university emergencies from the perspective of the public opinion lifecycle and proposes corresponding governance strategies. The sample consisted of 304 cases of real-life public opinion, and the visualization results show that public opinion on mental health and teacher-student safety constitutes the predominant types, accounting for 83.3%. High-occurrence subjects are public universities (88.24%) and students (48%). The most frequent months are July and December. 90.20% of the public opinions have a lifespan of less than 19 days, with an impact index ranging from 40 to 80. The public's emotional response to different types of public opinion varies, with negative emotions dominating. This study provides novel insights for understanding their formation and dissemination. It also provides practical implications for relevant departments to govern network public opinion on university emergencies.

Семантика неполноты действия в русском, украинском и английском языках

Semantic categories can be studied effectively using a comparative approach, since it allows to determine the general and specific features of the object under study against the background of the languages under consideration, but also to see the peculiarities of native speakers’ perception of the surrounding world. This is also relevant for the category of aspectuality. The discoveries of Slavic aspectology of the 20th century were actively used to study aspectual semantics in other Indo-European languages, including Germanic ones, in which the category of aspectuality has a different character and structure. Some questions in this field still remain controversial, with certain aspectual meanings requiring further study. This research focuses on the semantics of incomplete action in verbs and verb combinations of the attenuative mode of action in the Russian, Ukrainian, and English languages. The type of aspectual meaning under consideration is related to the idea of a partially complete action, action lasting for a short period of time, or insufficient to obtain a full result. Prefixal verbs with diminutive and related meanings are numerous in Slavic languages, which is explained by a developed verbal prefixation in general and special features of speakers of Slavic languages. A comparison of “attenuative” verbs and verbal units in Russian, Ukrainian, and English makes it possible to identify the main meanings of incomplete action in these languages and assess the productivity of their formation patterns in the compared languages. The study has demonstrated the variety of means to express the incompleteness of an action (prefixes, suffixes, adverbial combinations, etc.) in the compared languages, as well as the synthetic way of expressing the specified semantics in Russian and Ukrainian and the analytical way in English. This is explained both by the predominantly analytical structure of English as a whole, and by the likely lesser significance of attenuative meanings for English speakers when actualizing the inner parameters of the action. The analysis has demonstrated the following meanings of the studied units in the languages under consideration: 1) incompleteness of an action and its lesser result; 2) limited action in terms of its duration; 3) simultaneous incompleteness of an action and its complementarity, an addition of something to it; 4) lesser degree of an action, its sporadic character. Individual aspects of the meanings of incompleteness in compared languages do not coincide and and are in the relations of intersection.

Organic aerosol formation from 222 nm germicidal light: ozone-initiated vs. non-ozone pathways.

Germicidal ultraviolet lamps outputting 222 nm light (GUV222) have the potential to reduce the airborne spread of disease through effective inactivation of pathogens, while remaining safe for direct human exposure. However, recent studies have identified these lamps as a source of ozone and other secondary pollutants such as secondary organic aerosol (SOA), and the health effects of these pollutants must be balanced against the benefits of pathogen inactivation. While ozone reactions are likely to account for much of this secondary indoor air pollution, 222 nm light may initiate additional non-ozone chemical processes, including the formation of other oxidants and direct photolytic reactions, which are not as well understood. This work examines the impacts of GUV222 on SOA formation and composition by comparing limonene oxidation under GUV222 and O3-only control conditions in a laboratory chamber. Differences between these experiments enable us to distinguish patterns in aerosol formation driven by ozone chemistry from those driven by other photolytic processes. These experiments also examine the influence of the addition of NO2 and nitrous acid (HONO), and investigate SOA formation in sampled outdoor air. SOA composition and yield vary only slightly with respect to GUV222vs. ozone-only conditions; NO2 and HONO photolysis do not appreciably affect the observed chemistry. In contrast, we observe consistent new particle formation under high-fluence 222 nm light (45 μW cm-2) that differs substantially from ozone-only experiments. This observed new particle formation represents an additional reason to keep GUV222 fluence rates to the lowest effective levels.

Patterns of bilateral military alliances formation and political regimes in Central Europe, 1962-2003

This study examines the dynamics of political regimes as pivotal factors shaping bilateral military alliances (BMAs) in Central and Eastern Europe (CEE) from the aftermath of the Cuban Missile Crisis (1962) to 2003. Using data from the Alliance Treaty Obligations and Provisions (ATOP) and the Polity IV databases, the research investigates statistical correlations between the formation of military alliances, their typologies, and political regime-type dynamics. Research questions include exploring the key characteristics of BMAs, the political regime nature of dyads, correlations between alliance durability and democracy levels, and the impact of regime changes on alliance phases. A sample of 88 BMAs is analysed, exploring hypotheses on relationships such as alliance duration, political regime congruity, member asymmetry, treaty provisions, and changes pre- and post-Cuban crisis. Key findings indicate that less democratic dyads tended to sustain longer alliances, while the hypothesis on political regime congruity in military alliances received partial support. The study contributes to understanding how political regime dynamics influence alliance formation and longevity in a region historically shaped by the Cold War geopolitical dynamics.

НОВЫЕ СОРТА КАРТОФЕЛЯ ДЛЯ ВОЗДЕЛЫВАНИЯ ПРИ ОРОШЕНИИ В НИЖНЕМ ПОВОЛЖЬЕ

Purpose: to conduct an environmental-geographical test of new highly productive potato varieties of domestic and foreign selection during sprinkling under conditions of hydrothermal tension in the Lower Volga region. Materials and methods. Ecological testing of new highly productive 19 potato varieties and hybrids of domestic and foreign breeding was carried out at the experimental site of the All-Russian Research Institute of Irrigated Agriculture in 2022–2023. The studies were conducted in accordance with the requirements of generally accepted methods. Results. The results of the study on the selection and testing of potato varieties showed that the maximum amount of above-ground mass of the studied potato varieties was formed in the first decade of August, the maximum growth of tops was noted in the Kupets variety and hybrid 16.18-2, 750 and 700 g respectively. The Vega, Luck, Healer, Elixir, Gourmet varieties and hybrid 45.82-12 formed the vegetative mass from 500 to 630 g. Other varieties were unable to form a powerful vegetative mass. The Gulliver variety is characterized by the highest productivity of the studied potato varieties – 4.3 t/ha. The minimum potato tubers yield was obtained in the Lubava variety, which amounted to 15.6 t/ha. The formed potato tubers yield of other varieties and hybrids ranged from 18.7 to 34.0 t/ha. Conclusions. As a result of the conducted research, results were obtained on the patterns of tubers yield formation of 17 varieties and 2 potato hybrids undergoing environmental testing. The yield of varieties and hybrids of domestic and foreign breeding ranged from 15.6 to 41.3 t/ha, however, such varieties as Gulliver, Luck and Darenka, Red Scarlett, Colombo, Queen Anna and hybrids with yields above 30 t/ha should be highlighted.

The Pattern of Granuloma Formation in the Liver of Rats as a Reflection of the Mechanism of Internalization of Submicron Silicon Particles.

A morphological analysis of the liver of Wistar rats was performed 2 months after a single intravenous injection of porous silicon particles of different sizes (60-80, 250-300, and 500-600 nm; 2 mg/ml, 1 ml). Histological, immunohistochemical, and electron microscopic methods showed the development of CD68+ granulomas in all experimental groups. Injection of 60-80-nm porous silicon particles led to the formation of single large granulomas (>2000 μm2), while 500-600-nm nanoparticles caused the formation of numerous smaller granulomas. The mechanism of involution of granulomas by apoptosis of Kupffer cells and the absence of subsequent connective tissue remodeling of the organ tissue is shown.

ОЦЕНКА ИЗМЕНЧИВОСТИ ПОКАЗАТЕЛЕЙ БИОХИМИИ КРОВИ ГИБРИДОВ СВИНЕЙ С ИСПОЛЬЗОВАНИЕМ МОДЕЛИ ЛИНЕЙНОГО УРАВНЕНИЯ

In modern pig farming, when producing meat products, special attention is paid to interbreeding and hybridization. Crossbreeds are characterized by a higher level of productivity, which is due to better vitality compared to purebred animals. Biochemical studies of animal blood have always occupied a prominent place among the methods for objective assessment of metabolic processes in the body and the patterns of formation of economically useful traits. The study of blood parameters makes it possible to observe an objective lifetime assessment of the intensity and direction of metabolism, the course of physiological processes in the body, the level of nutrition of animals, and their health status. Therefore, in accordance with the above, knowledge of the nature and patterns of variability in the biochemical parameters of pig hybrids is of particular interest. Our article reflects the results of a study of biochemical blood parameters of three-breed hybrid pigs.

Investigation of the purpose, functions and tasks of proceedings in cases of administrative offenses

The object of the study is the general purpose and function, as well as the tasks of the proceedings in cases of administrative offenses. The interdependence and relativity of the concepts of "purpose" and "task" of proceedings in cases of administrative offenses cause difficulties in establishing their distinctive features and mutual differentiation, and therefore the issue of defining these categories in the science of administrative law is currently debatable. For this reason, the works of prominent Russian jurists such as D. N. Bakhrah, V. V. Dorokhin, S. D. Mogilevsky, A. Y. Yakimovich, revealing the content and essence of these concepts from different sides, formed the subject of this study. The specificity of the research object was a decisive factor in determining the research methodology. In preparing the article, a set of general scientific and private scientific methods was used, including the method of system analysis, which ensured the validity of the author's judgments, suggestions and recommendations. Within the framework of a systematic analysis, directing the research process from a complex to a simpler manifestation of the object of research, the author, based on the patterns of formation of tree-like hierarchical structures, reveals the content of the above concepts in an original way, defines the general law-restoring nature of production, identifies the law enforcement stages in it, as well as the goals and special tasks of each stage. As a result of the research, the author's version of Article 24.1 of the Code of Administrative Offenses of the Russian Federation is proposed, which establishes a legal definition of the purpose of proceedings in cases of administrative offenses. Proposals for improving the current legislation indicate the applied significance of this study, while some conclusions and theoretical generalizations of the author can be used to conduct further research in this direction.

Some mechanisms of formation of intrapersonal and interpersonal conflicts related to the personality characteristics of the Dominant and Subordinate person in the parental family

The object of the study is the patterns of formation of intrapersonal and interpersonal conflicts, which are the result of the desire to rise above the Dominant family member and not live life as a subordinate family member. The conflicts arising in the process of realizing the following desires were analyzed: 1) to realize a dream that the Dominant could not realize; 2) to possess the skills and qualities of people in relation to whom the Dominant felt feelings of delight, respect, admiration, awe, envy; 3) to do what the Dominant was afraid of (or do something that could frighten the Dominant); 4) not to fall into the category of people that the Dominant considered "weaklings"; 5) to do something that could cause impotent rage (panic) in the Dominant; 6) to have such skills or qualities that the Dominant was proud of, took credit for; 7) to have those skills and qualities that the person possessed, who has managed to rise above the Dominant One in some way; 8) marry a person who will help realize the above desires, etc.n This work is a qualitative study of a structured interview, which was previously the subject of a quantitative study published earlier. The detailed answers of the subjects were classified according to the types of conflicts described in them. The novelty lies in the fact that on the basis of these basic aspirations, a number of private needs have been identified, the inability to satisfy which leads to intrapersonal and interpersonal conflicts. A cognitive distortion has been revealed regarding the "helplessness" and "inoffensiveness" of people of the same sex as the Subordinate. The following personality structure is proposed: 1) ideas about what is "strong" behavior (based on the child's observation of the Dominant behavior, which ensures success in the eyes of a Subordinate); 2) ideas about what is "weak" behavior (based on observation of the Subordinate's behavior, which, from the child's point of view, makes him a slave) 3) ideas about "strong" and "weak", "decent" and "unworthy" behavior that exist in society. It is assumed that the driving force of personality development is the resolution of contradictions found by the child between these three elements.

Experimental study of the development of centrifugal circulation in a liquid under various boundary conditions

In this work, an experimental study was carried out on the formation of the structure of a limited vortex flow of a liquid swirled by a flow of another liquid or a gas vortex. The results obtained were compared with the structures that arise in closed vortex reactors, where the movement in the working volume is formed by a rotating disk. During the work, patterns of formation of circulating vortex cells in liquid were revealed. A similarity of the flow structure in the working fluid is observed, regardless of the method of creating the swirl (solid disk, liquid vortex, air vortex).

ЗОНАЛЬНОСТЬ ПРОФИЛЯ ВЫВЕТРИВАНИЯ СРЕДНЕПЕРМСКИХ ПЕСЧАНИКОВ НА ТЕРРИТОРИИ ВОСТОЧНОГО ЗАКАМЬЯ

This work is about the study of the main patterns of formation of eluvium sandstones in the territory of the Eastern Zakamye. It is a large industrial region on southeastern part of the Republic of Tatarstan. For the thicknesses of the Middle Permian sandstones, the zonal character of their structure, physical and mechanical properties, chemical and mineral composition has been established in accordance with the degree of their hypergenic change. Information has been obtained on the elemental composition of sandstones and its changes during weathering. Based on the systematization and analysis of field studies, regional dependencies between the parameters of cone penetration test and the strength and deformation characteristics of soils are constructed. The results are of great practical importance and make it possible to optimize the design and construction of infrastructure in a given area

The parameters of flow-forming elements for controlling the behavior of fish in artificial channels.

The current level of anthropogenic impact on open water sources shows a decrease in the quality of surface runoff, a constantly growing volume of water withdrawal for economic purposes, exerting the greatest significant impact and damage on the hydrobiological resources of water sources. The processes of interaction between subjects of hydro-biocenosis force us to study the mechanisms of interaction between fish, water flow, and hydraulic structure (channel), including the optimization of elements of hydraulic structures that affect the environmental safety of a water source as a whole. We noted the main formation patterns of the structure of a turbulent flow and its interaction with a hydraulic structure (channel), such as the pulsating nature of the aquatic environment, heterogeneous structure, gradient nature, and vortex structure. We analyzed the advantages and features of the effect of three-dimensional flow-forming elements on the behavior of fish. We developed the design and method of designing a bottom flow-forming element for controlling the behavior of fish in a river flow, substantiated geometrical parameters, created an optimal layout of bottom flow-forming elements in artificial channels. We provided an assessment of the use of technical solutions for flow-forming elements of existing and reconstructed fish protection facilities.

Анатомическая лексика в якутской оронимии

The article focuses on orographic appellatives and oronyms derived from anatomical terms in the Yakut language through metaphorization. Given that the Yakut oronymy is endangered due to several sociolinguistic and socio-economic reasons, collecting, systematizing, studying, and preserving this specific layer of the Yakut toponymic lexicon in linguistic databases is relevant. We have identified more than 80 anatomical terms that contributed to the Yakut oronymy development. We divided the Yakut anatomical vocabulary used as orographic appellatives into two groups: 1) lexemes denoting the external parts of human and animal bodies and 2) lexemes denoting the internal organs of humans and animals. The comparative analysis covered the following anatomical terms: atax ‘leg’, bas ‘head’, sürex ‘heart’, tumus ‘nose; beak’, kulgaax ‘ear’, töbö ‘head’, meyii ‘brain’, emiy ‘udder’. The comparison has demonstrated a substantial similarity in the anatomical vocabulary used as orographic appellatives in the Turkic languages. However, some Turkic languages feature divergence in terms of content, possibly resulting from the influence of contact languages (related and unrelated). The abundance and variety of metaphorical anatomical terms in different Turkic languages may also be due to the physical and geographical features of the terrain on which they function. Given the above, the anatomical vocabulary can be considered an additional source for understanding the formation patterns and features of the Turkic-Mongolian geographical vocabulary of Siberia.

Сухой порт Северного морского пути в концепции формирования Урало-Арктического сектора России

Russia strives to develop its Arctic territories and projects for their integrated use, as well as the Northern Sea Route. These tasks can be solved by prioritising the connectivity of Russian regions. The article presents a strategic analysis and conceptual justification of the project “Dry port of Ekaterinburg”, which was created in 2022. The study proved that the project has been gaining importance during implementation as an element of the emerging Ural-Arctic sector of Russia, acting as an aqua-territorial system and a specific object of spatial development. The concept of a dry port on the Northern Sea Route (a system of complementary ports) was proposed. The uniqueness of the dry port on the Northern Sea Route (level I subsystem) in the middle megaregion due to its scale was assumed. Examination of the Greater Urals megaregion confirmed that Ekaterinburg should be at the top of the hierarchy of the dry port system considering Arctic factors and formation patterns of the supporting framework of intersecting transport corridors. Methods of spatial and economic analysis, synthesis of distributed systems, system modelling were utilised. The authors proposed a multi-criteria ranking of planned railway lines between Ural regions and ports on the Northern Sea Route under fundamentally incomplete and unreliable source data. The following criteria were used in the ranking: diversification, cargo formation, resource and technological capacity building, transport accessibility, and project investment financing. The ranking results revealed that a new railway line connecting the Northern Urals with the multifunctional Indiga port under construction on the Northern Sea Route is seen as preferable. The study offered a reasonable set of proposals for implementing the Ural-Arctic dry port in the Middle Urals.

Global Consensus-Based Formation Control of Nonholonomic Mobile Robots With Time-Varying Delays and Without Velocity Measurements

We propose a solution to the full consensus-based formation problem for torque-controlled nonholonomic mobile robots under time-varying communication delays and without velocity measurements. Under the assumptions of static and undirected communication topologies, and smooth and bounded delays, we propose a distributed smooth, time-varying control law which achieves the goal of acquiring a global formation pattern in a common consensus point for <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">both</i> position and orientation. The controller is a combination of a simple Proportional-Plus-Damping scheme and a simple globally exponentially convergent velocity observer. Consensus is reached independently of all initial conditions. Realistic simulations in the Gazebo-ROS environment illustrate the effectiveness of the proposed algorithm and the robustness with respect to measurement noise, non-smooth delays and uncertain dynamics.

The Phonological Process in the Plurality of Pashto Nouns

This research aims to provide a comprehensive representation of the intricate phonological processes involved in Pashto noun pluralization. The study focuses on identifying these phonological processes, examining the patterns of plural formation, and understanding their implications for Pashto's phonological structure. To obtain the objectives of the study, the researchers collected the data from the native speakers of Pashto especially joined the elders. Along with this, the data were collected from Pashto books, magazines and dictionaries followed by the discussion of experts. The finding of the study showed that Pashto carries complicated pluralization of noun phonologically. It revealed that there are nouns having single pattern, two patterns, three patterns, four patterns and some nouns even don’t carry plural form. This complexity underscores Pashto's versatility conveying precise meanings and contextual differences through diverse pluralization forms, distinguishing it from other languages.

Features of the Geological Structure and Polymetallic Mineralization of the Uspensky (Central Kazakhstan) and Dalnegorsky (Far East) Ore Districts

Polymetallic deposits of lead and zinc are of great importance in the economy of the developed countries of the world. Kazakhstan is among the world leading countries in terms of reserves and production of lead and zinc. There are large ore regions with polymetallic mineralization; these are the deposits of the Atasu and Uspensky ore regions in Central Kazakhstan. The former are genetically related to the final (taphrogenic) phase of the development of the large orogenic structure in the Central Kazakhstan (the Devonian volcano-plutonic belt), with the period of Late Frasnian-Famenian-Early Carboniferous formations of thick carbonate and carbonate-terrigenous sediments, including significant reserves of stratiform lead-zinc ores. Polymetallic mineralization of the Uspensky zone is singled out as an independent genetic Alaygyr type, and the tectonic nature of the ore-bearing Uspensky zone, as well as mineralization of this type, is still the subject of constant discussions. In this regard, the comparative characteristics of the Dalnegorsky and Uspensky ore regions, which have certain similarities in geodynamics, magmatism and metallogeny, are of great importance not only for solving the issues of the general patterns of formation, factors and criteria for controlling lead-zinc mineralization but also for an objective assessment of the ore potential of these and similar areas with polymetallic mineralization. Research methods: comparative analysis of the results of petrographic, chemical and mineralogical studies of ores enclosing near-ore metasomatically altered rocks and intrusions of different age and composition.

Analysis of the process of emergence and development trends of Ukrainian and Eastern national types of martial arts

Background and Study Aim. National types of martial arts have been created and are functioning in Ukraine, which are gaining more and more popularity in the world. Modern sports science investigates the history of the creation of national types of martial arts. The purpose of the article is to investigate the historical origins of the emergence and development of Ukrainian and Eastern national martial arts. Material and Methods. 217 sources of information on the history of traditional Ukrainian martial culture were analyzed. Bibliometric methods of processing the received information were used. After the initial analysis, 34 sources were selected, which fully correspond to the purpose of the study. Results. The stages of the formation of the Ukrainian nation are quite fully covered in scientific historical sources. The mutual connection between the development of society and its martial culture is shown. It is reliably known about the presence of military training in the era of the Trypil culture (approx. 5400 - 2750 BC). It is shown that the complication of social relations and the development of material production created conditions for the separation of the caste of professional warriors. Professional soldiers conducted specialized training for weapons and physical fitness. In combat units, young men were trained for combat operations. The military training of professional soldiers reached its maximum development during the period of existence of Kyivan Rus (IX-XIII centuries of the new era). Literary sources provide information that the national physical culture developed at the same time as the complex of military-applied youth training. The training included fencing with various types of weapons, archery and types of unarmed combat. On the banks of the Dnieper, on the island of Khortytsia, the Cossacks formed the military society of Zaporizhzhya Sich (16th - 18th centuries of the new era) and on a systematic basis conducted preparations for conducting military operations. Varieties of fencing, wrestling and fist fighting were developed at a high level. Data given in scientific sources indicate that the Cossack martial arts became the basis of modern Ukrainian national types of martial arts. In Japan, in the process of the foundation of the country (1603-1868 years of the new era), a national martial culture was formed based on the training of samurai warriors. Conclusions. The bibliometric analysis of publications on the history of Ukraine determined the correlation between the stages of the formation of the Ukrainian nation and the development of the military culture of Ukraine. The significant influence of religion on the consciousness of Ukrainians makes it possible to divide martial arts into pre-Christian (Trypylian and Indo-European cultures) and Christian (Kyiv Rus, Zaporizhzhya Sich). A comparison of the emergence and development of traditional national martial arts of Ukraine and Japan makes it possible to highlight the general patterns of formation of modern national types of martial arts.
