This paper is devoted to modeling the propagation of seismic waves in a chemically inert elastically deformable rock. Only changes in stress and pore pressure are considered, and the chemistry of the saturating pore fluid does not directly affect the deformation of the rock. Chemical effects are taken into account by changing pore pressure and rock deformation in the transport equations. In the numerical solution of the problem under consideration, an algorithm is used to combine a Laguerre integral transform method and a finite difference method. The results of modeling the transport of a dissolved substance through a semi-permeable clay shale are presented.
The study aims to provide a comprehensive bibliometric analysis of the academic literature on artificial intelligence (AI) ethics and social dynamics. Publications between 2020 and 2025 from Web of Science and Scopus databases were examined. The study aims to reveal expose the evolution, patterns, geographic distribution, and multidisciplinary structure of the subject of AI ethics. With an increase of over 100% in both databases, particularly between 2023 and 2024, the results show that the field has displayed fast expansion recently. Though there are variations in production and influence, the USA, the UK, and China dominate the field. Journal analysis shows that the journal “AI & Society” is the most influential publication in both databases. Keyword and thematic analyses show that while “AI”, “ethics” and “machine learning” remain central, new themes such as “ChatGPT” and “generative AI” are on the rise. Author collaboration networks reveal the multidisciplinary nature of the field and the existence of diverse research groups. Differences in coverage between databases suggest that Scopus better represents health sciences and current technological developments, while WoS better represents ethics. This study emphasizes that the research agenda in the field of AI ethics should be more inclusive and based on interdisciplinary collaboration and provides recommendations for future research directions.
В статье рассматривается влияние физической активности на здоровье человека с акцентом на ее роли в улучшении репродуктивной функции и решении современных демографических проблем. На основе анализа отечественных и зарубежных исследований выявлены ключевые механизмы в преодолении демографических проблем общества. Кроме того, представлено исследование, проведенное среди студентов высшего учебного заведения, в рамках которого осуществлено анкетирование по вопросам физической активности, осведомленности о ее влиянии на здоровье и репродуктивные функции. Результаты анкетирования позволяют оценить уровень вовлеченности молодежи в занятия спортом и их отношение к здоровому образу жизни. Выводы подчеркивают необходимость внедрения программ популяризации физической активности как средства повышения репродуктивного здоровья населения и решения вопросов рождаемости. Статья ориентирована на ученых, практиков и специалистов в области социальной политики, развития спорта и медицины, а также широкий круг читателей, интересующихся вопросами здоровья и демографии.
The article investigates the effectiveness of sulfur-asphalt concrete in road construction, with particular emphasis on the advantages of using technical sulfur as a modifier for asphalt concrete pavements. The study reviews and analyses the sources of sulfur supply and consumption. A classification of technical sulfur is provided, and the types of sulfur suitable for use in road construction are identified. The results demonstrate that incorporating sulfur into asphalt concrete mixtures significantly improves pavement resistance to rutting, as well as its strength and elasticity. It was also established that using sulfur as a bitumen modifier can reduce material production costs. In terms of strength characteristics, sulfur-asphalt concrete exhibits greater resistance to temperature variations. The conclusion provides recommendations for the application of sulfur-asphalt concrete in road construction and related industrial sectors.
This study aims to prove that Donald Trump’s internet posts implement the rhetorical strategy of the “Spielbrecher”, which sets a precedent for changing the norms of political communication in mediatized discourse. Drawing on the theories of J. Huizinga and L. Wittgenstein, the author views political communication as a language game whose rules and boundaries are violated by the “Spielbrecher” in order to establish a new game with different rules. The author identifies lexical, stylistic, and syntactic markers of systematic violations of institutional political communication norms in Trump’s posts. These violations constitute a process that gradually blurs the boundaries of what is acceptable in political communication. The study’s scientific novelty lies in identifying, for the first time, the structural elements of the rhetorical strategy “Spielbrecher”. The study identifies three stable elements of the narrative scenario (polarization, ultimatum, avoidance of responsibility); three groups of lexical repetitions (positive evaluation, negative evaluation, threat markers); three categories of speech tactics (construction of alternative reality, annihilation of the opponent, coercion combined with avoidance of responsibility); and four binary oppositions that organize the semantic space of the posts.
