This article presents the information on the valorization of waste generated during the production of tissue paper. The possibility of bioconversion of the polysaccharide part of paper sludge into simple sugars has been evaluated. The options for processing the paper sludge before enzymic hydrolysis to achieve the maximum yield of monosaccharides have been considered. Pretreatment with acids has been found to be a key step before the biocatalytic cleavage of waste polysaccharides. An additional yield of enzymic hydrolysis products after pretreatment with acids has been obtained by pre-extraction of the paper sludge with spirit or acetone. It has been established that the most intense enzymic hydrolysis of readily available fractions of the paper sludge takes place in the first 10–12 hours. Further, the process slows down, probably due to the action of the remaining components of the fillers, as well as an increase in the proportion of the difficult-to-hydrolyze polysaccharide part. In all cases, the proportion of absolutely dry non-hydrolyzed residue has been about 43±2 % of the dry matter of the paper sludge. The main products of enzymic hydrolysis have been glucose and xylose. The resulting sugars have been used for mixotrophic cultivation of the Tetradesmus obliquus and Chlorella vulgaris algae. Yeast strains have been selected for the conversion of monosaccharides from the paper sludge. In a series of experiments on non-sterile yeast cultivation, the Candida utilis PAL D and Debaryomyces hansenii SWING R cultures have turned out to be the most productive (within 2.10±0.14 g of air-dry yeast weight/dm3 per 24 hours). The degree of conversion of hydrolysate sugars has been 70±2 %. Most of the remaining sugars (about 80 %) have been represented by xylose. Complete utilization of the sugars has taken place on the 2nd day when having added an extra nitrogen source to the medium. On the other hand, the spent nutrient medium after yeast separation has been suitable for mixotrophic cultivation of microalgae. It has been revealed that the economic costs of pre-treatment of the paper sludge with nitric acid can be leveled by using the resulting salts as a nitrogen source for cultivating yeast. In doing so, the yield of yeast biomass increases by almost 2 times.

The article introduces attraction marketing methods employed by Russian monthly popular science magazine Diletant. The authors compared the printed version and the website. The paper magazine attracts the reader mainly by the topic name printed on its cover as a unique creolized text. The further semantics of the front media text includes various aspects of the main topic. Color highlights both topical issue and regular features. The comparative analysis with the online version revealed some significant differences. The website has a muted color scheme and minimal animation; it contains neither video nor audio materials. Like in the printed version, the function of attraction belongs mainly to illustrations and subtitles. Online Diletant is interactive in navigation, tests, and surveys, which are, however, the only form of interactivity: the site does not provide comments, forums, “likes”, etc. Such limited use of attention-seeking tools makes the digital version of Diletant uncompetitive and inferior to its paper issue.

The paper considers the question that has gained relevance in the last decade: whether the cryptocurrency bitcoin is money. The economic literature provides different opinions on this issue. The analysis shows that disagreements arise because of the different understanding of the category of ‘money’ rather than because of the nature of bitcoin. The author analyzes popular interpretations of money in terms of their applicability to the definition of the role and place of cryptocurrencies in the financial system. The purpose of this study is to define money as a financial instrument that linksthe creation of gross social product with its distribution. The author believes that money emerged and exists as a tool that ensures a connection between the contribution of each economic entity to the total product of society and the right to receive an equivalent amount of goods from this gross product. At the same time, the author defines money as an ‘ideal right’ to receive a share of the gross social product. In this regard, the analysis of bitcoin shows that this cryptocurrency allows obtaining goods from the gross social product in many countries, while bitcoin owners do not contribute to the gross social product. Based on this, bitcoin cannot be considered money; it is a money substitute, or surrogate money. At the same time, bitcoin was created as money and performs the functions of money, but to a limited extent. Bitcoin can only perform the functions of money as a supplement to an existing official currency. It is not capable of functioning as the only currency in a society. The interpretation proposed in this paper can be used for the purposes of developing the Russian law on cryptocurrencies is currently being worked on by the Government and the Central Bank of Russia.

This paper examines the Talyshi people, an Iranian ethnic group divided by the Araxes River between Azerbaijan and Iran. The division, a result of the Russo-Persian War (1804-1813), placed the Talyshis within two distinct political and cultural paradigms. The northern Talyshis, under the successive rule of the Russian Empire, the Soviet Union and Azerbaijan, were confronted with a Turkish political and cultural orientation that contrasted with their Iranian linguistic and cultural heritage. This orientation led to significant shifts in identity, with the Talyshis becoming minorities within a Turkic-speaking, Turkish-oriented Azerbaijan. Southern Talyshis who remained in Iran experienced a more consistent cultural development within the Iranian paradigm, despite political changes. This study examines the impact of these divisions on Talyshi identity, language preservation and socio-cultural adaptation. It discusses the challenges of assimilation and cultural preservation faced by the Talyshis, their linguistic characteristics, and the revival of Talysh self-awareness and nationalism in the face of external pressures. The paper uses a comprehensive analysis of historical, linguistic and ethnographic data to provide insights into the resilience of Talysh identity amidst political and cultural change.

This paper examines the practice of female genital mutilation (FGM) among the Dawoodi Bohra community in Pakistan. FGM, a non-therapeutic alteration of the female genitalia, is examined through the lenses of religion, culture and health. The Dawoodi Bohra, predominantly based in Karachi, practice FGM as a religious and cultural rite, linking it to notions of purity and social acceptance. Despite global efforts to outlaw and eradicate FGM, it persists, underpinned by deeply held beliefs and the insular nature of the community. The physical and psychological effects of FGM are profound, leading to immediate and long-term complications such as severe pain, infection and psychological trauma. This paper discusses the impact of these practices on women’s health and rights, while critiquing the lack of an effective legal framework in Pakistan to combat FGM. In addressing this issue, the paper contributes to the broader discourse on gender-based violence and the rights of women and children in patriarchal societies.

Modern energy systems are often used as a medium for information transmission, including confidential information, which makes relevant the task of ensuring its security, which today is solved using not only cryptographic but also steganographic means that ensure concealment of the very fact of confidential information transmission. The steganographic method with code control of the additional information embedding possesses practical important qualities, but in its original form requires the presence of a container for successful information extraction, which is not always desirable in practice, while the known modification of this steganographic method allows blind decoding is characterized by an insufficient level of resistance to attacks against the embedded message. The purpose of this paper is to improve the efficiency of the steganographic method with code control of the additional information embedding and blind decoding. This purpose was achieved by identifying two factors that determine the occurrence of errors during blind decoding of additional information in the steganographic method with code control: variation of sub-blocks, and errors caused by attacks against the embedded message. We pro-pose the theoretical and practical rationale for codewords that provide the best level of re-sistance to both factors. The most significant result of the paper is a reduction in the number of decoding errors of the steganographic method with code control of the additional information embedding and blind decoding by 12.01% compared to the result known in the literature through a reasonable choice of codewords used to embed the additional information.

This article expands upon the author's previous work regarding the Vostok Oil project, initially discussed in the Gubkin University journal. It focuses on the establishment and development of the Zvezda Shipyard project, arguing its critical role in the potential development of the Vostok Oil and Gas province. The paper posits that without the Zvezda Shipyard, it would not be feasible to exploit the Vostok Oil and Gas province or significantly enhance the transportation and logistics capabilities of the Northern Sea Route (NSR). The development of Zvezda's new production facilities is presented as essential for the advancement of the Russian Arctic, facilitating a pivotal eastward shift in the Russian economy. The significance of the Zvezda project and the strategic decisions leading up to it are discussed in detail, demonstrating how they integrate the development of the NSR, the exploitation of Vostok Oil fields, and the establishment of investment and technological foundations for Russia's long-term strategy. This strategy addresses both socio-economic goals and defense and security challenges. Additionally, the paper provides quantitative analyses of the multiplicative effects generated by the Zvezda Shipyard project's realization.

Personalization is one of the keyways to improve the performance of conversational agents. It improves the quality of user interaction with a conversational agent and increases user satisfaction by increasing the consistency and specificity of responses. The dialogue with the agent becomes more consistent, the inconsistency of responses is reduced, and the responses become more specific and interesting. Training and testing personalized conversational agents requires specific datasets containing facts about a persona and texts of persona’s dialogues where replicas use those facts. There are several datasets in English and Chinese containing an average of five facts about a persona where the dialogues are composed by crowdsourcing users who repeatedly imitate different personas. This paper proposes a methodology for collecting an original dataset containing an extended set of facts about a persona and natural dialogues between personas. The new RuPersonaChat dataset is based on three different recording scenarios: an interview, a short conversation, and a long conversation. This is the first dataset for dialogue agent personalization collected which includes both natural dialogues and extended persona’s descriptions. Additionally, in the dataset, the persona’s replicas are annotated with the facts about the persona from which they are generated. The methodology for collecting an original corpus of test data proposed in this paper allows for testing language models for various tasks within the framework of personalized dialogue agent development. The collected dataset includes 139 dialogues and 2608 replicas. This dataset was used to test answer and question generation models and the best results were obtained using the Gpt3-large model (perplexity is equal to 15.7). The dataset can be used to test the personalized dialogue agents’ ability to talk about themselves to the interlocutor, to communicate with the interlocutor utilizing phatic speech and taking into account the extended context when communicating with the user.

The subject of the research in the paper is academic ethics in the professional relationships of university teachers. The final results are presented on the basis of in-depth interviews with representatives of the academic staff of Russian universities (N=35). The purpose of the paper is to show how academic ethics as a value-normative phenomenon supports the professional relationships of academic staff at the university and forms certain values that ensure the effectiveness of the scientific and educational process. In this interpretation, the emphasis is placed on identifying the creative potential of academic ethics, its impact on the scientific and educational process at the university in terms of professional interaction of its main subjects. An assessment of the structure and content of academic ethics is given. It is established that academic ethics, being an element of academism in the higher education system, influences the formation of value-normative attitudes of respect and recognition. In addition, the importance of this phenomenon for the strategic development of the university and at the same time the preservation of academic traditions is revealed. The article also summarizes the assessments of the state of academic ethics at universities formulated by informants. In such assessments, value-semantic reflection prevails, which makes it possible to identify academic ethics as a factor of effective professional interaction between subjects of the educational process in order to achieve joint goals for the formation of their value world and professional knowledge and skills.

The theory of academic exchanges emphasises the importance of international cooperation to improve the quality of education, stimulate innovation and promote cultural diversity. China and Russia are two major world powers with rich history and culture. The exchange of international students between the countries is an important aspect of the friendly format of cooperation in higher education. During such exchange, students can improve their foreign language skills, enrich their personal life experience, ensure high competitiveness in employment, and expand their knowledge and skills in the field of their profession. This paper analyses the current situation and predicts future directions of educational exchange through various prisms, including the experience of academic student exchange between universities in the two countries. It analyses the attitudes of Chinese students studying at SPbSU towards higher education in Russia. The author notes that academic exchanges and foreign learning experiences provide opportunities for international students to broaden their horizons and fulfil their emotional needs in study and life. Students from both countries have the opportunity to immerse themselves in a different cultural and academic environment, improve their intercultural communication skills and broaden their global perspectives. It also focuses on the opinion of Chinese students about the quality of higher education in Russia. Academic exchanges of students are of great importance for the state, as they act as instruments of forming «soft power» in another country, strengthen diplomatic relations between countries, form a positive image of the state, attract investments, etc. Thus, academic exchanges are a way for countries to develop cooperation at various levels - from educational to economic. Thus, academic exchanges are a way for countries to develop co-operation at various levels - from educational to economic. Purpose. To investigate the current state of the concept of academic student exchange between China and Russia, to study the significance of this international co-operation for the development of the higher education system. Methodology. The paper uses collection and analysis of information sources, historical method, comparison and generalisation, survey with the help of the author's questionnaire. SPSS Statistics 23 software is used to analyse empirical data. Results. The result of the work is the identification of the peculiarities of the sphere of academic exchange of students between China and Russia, the determination of the importance of this cooperation for the development of the higher education system at the international level. The author concludes that cooperation in the development of innovations in key areas of education contributes to the smoothing of cultural differences between the countries, and expands opportunities for students of both countries in higher education. Practical implications. The results of the study can be used in the educational sphere of international cooperation. Teachers and specialists involved in planning the educational process in the university sphere have the opportunity to create an innovative approach to improve the academic exchange programme for students, taking into account the socio-cultural criteria analysed in the article.

Accounting and finance are intricately intertwined with the global quest for environmental sustainability by applying accounting and finance tools for carbon reduction initiatives. Clean energy financial investment is one of the many alternative tools through which accounting contributes to carbon reduction. Accordingly, this paper analysed the impact of separate and integrated clean energy investment alternatives on carbon reduction. Data on clean energy financial investment and carbon emission per capita were collected from the International Energy Agency (IEA) and Our World in Data archives, respectively. Data was analysed by using multiple pooled OLS to evaluate the impact of individual clean energy financial investments on carbon reduction and the impact of integrating the various clean energy financial investment alternatives on carbon reduction separately. Findings show that individual clean energy financial investments may not separately offer desired carbon reduction, hence, albeit some negative coefficients, individual clean investments showed no significant impact on carbon reduction. However, furthering the test by pooling all the clean energy financial investment alternatives shows a significant negative effect of clean energy financial investment on carbon reduction at a P-value of 0.05. This shows that an integration of different alternatives of clean energy financial investment may offer an enhanced reduction of carbon emission, which outweighs the effect of relying on a single clean energy investment alternative. The findings offer significant insight for policy makers’ future strategies towards a combination of multiple clean energy financial investments. Furthermore, the findings from this paper are a further testament that accounting and finance are connected with the global quest for environmental sustainability through the application of accounting and financial investment tools in conducting clean energy financial investment.

The search for alternative sources of useful minerals is a pressing issue. One such possible source is the processing of lean gold-bearing ores, which previously did not seem feasible to exploit for subsoil users, leading to their disposal in off-balance ore dumps. Processing these resources becomes economically viable as gold prices rise and processing technologies improve over time. This paper presents the elemental and mineralogical composition of lean gold-bearing ore dumps from the Golden Pride Project (GPP) mining operation in Tanzania’s Lihendo district. This area contains an old dump of lean gold-bearing ores, weighing approximately 1.4 million tons. Extracting valuable components from lean mineral raw materials is a current priority. Sampling was conducted to study the dumps. Boreholes were drilled to a depth of 1 m, covering a total sampling area of 20 ha; 18 samples, each averaging 3 kg in weight, were collected. The results of X-ray fluorescence analysis (XRF) indicated the presence of Fe, S, Si, Ca, Ca, Mn, Cu, Al, Cr, Ti, As, and Ag in the collected samples. X-ray diffraction (XRD) analysis revealed that the main minerals in the dumps are muscovite, kaolinite, quartz, montimorillonite, and goethite. The average gold grade in the selected samples is 0.72 g/t. Studies of the grain-size distribution and gold distribution by grain-size classes after ore grinding demonstrated that the majority of gold (74%) is in the −75 μm class. In the initial mineral material of the dumps, the share of the +30-50 mm grain-size class is 81%. The paper proposes potential methods for processing lean dumps of gold-bearing ores. One such methods involves crushing the dump material, separating the −75 μm class, and subjecting it to direct leaching or leaching using “carbon-in-pulp” technique. Heap leaching appears to be the most promising method for extracting gold from such dumps in terms of technical and economic feasibility. Positive experience has been reported in applying this process to ores of similar mineralogical type.

Introduction. The paper discusses the advantages and features of the main existing methods of connecting wooden columns and crossbars.Materials and methods. It was proposed to increase the load-bearing capacity and reduce the deformability of joints by modifying the joints with the introduction of epoxy resin between the screw and the wood and between the overlay and the end of the wooden element to which it is attached and modifying the design of the overlays.Results. As a result, a constructive solution for connecting wooden columns and crossbars was developed, which has increased reliability compared to the studied connections and is free of their disadvantages. This result was achieved due to the presence of an adhesive layer between the screw and the wood, as well as between the overlay and the wooden element, the making of notches on the sides of the overlays attached to the wooden elements, the increased length of the screws screwed into the overlay with a groove, compared to the length of the screws screwed into an overlay with a tenon, placement of holes for screws at an angle of 90° to the surface of the overlay into which the screws are screwed.Conclusions. An urgent issue is the development of constructive solutions for connections of wooden elements, in particular the interfaces of columns and crossbars. The paper discusses the advantages and features of the main existing methods of connecting wooden columns and crossbars.

Objectives This paper focuses on recognising and addressing the challenges of ADHD in early childhood girls. The paper aims to fill a gap in the scientific literature by focusing on the specificity of ADHD in girls, which differs from symptoms in boys. It also aims to raise awareness of the issue of ADHD among parents and teachers and to provide practical therapeutic guidance and educational support that is tailored to the needs of girls with ADHD. Material and methods The source materials for this publication will be various monographs and articles by special educators. The collected material will allow the analytical-critical method to synthetically realise the indicated aim of the work. Results Parents should learn to anticipate potential conflict situations, to exclude them or to plan in such a way that the child can cope with them. It is the parents' task to plan the day in such a way as to introduce a ritual and a daily routine of repetitive activities. Children with Attention Deficit Hyperactivity Disorder need to acquire skills to deal with conflict, emotional labile, anxiety and stress. Conclusions Often undiagnosed girls suffer alone together with their disorder. Close cooperation between parents and teachers is an indispensable element in the treatment of ADHD. A child with ADHD should be allowed to participate in the educational and educational process. It is important to get to know the peer group so that girls with ADHD can learn to recognise themselves and their own reactions and abilities.

This paper indicates significance of generational diversity management in modern business. Due to certain social, political and economic circumstances each generation is specific, with its own skills, interactions and expectations. What is common for all of them is the willingness to find the right employer. The one open to human needs and aware of their work commitment; the one to offer appropriate work surroundings, self- development and adequate gratification. The paper is aimed at presenting those generational disparities, for awareness of them is crucial in efficient human resources management. Worksite is the natural environment, where such age-related experiences and opinions clash, enabling to gain the right perspective and choose the most effective and innovative directing solution. Generationally diverse team brings multilevel benefits for both sites and aids enterprise development.

The withdrawal of US troops and the rapid takeover of Kabul by the Taliban (recognized as a terrorist organization and banned in the Russian Federation) in Afghanistan in 2021 shocked the world community. Even though the PRC actively opposes international terrorism, which the Taliban movement (recognized as a terrorist organization and banned in the Russian Federation) is accused of supporting, it has become one of the few countries that have begun to cooperate with the new Afghan regime. In the light of these events, China’s view of the situation in Afghanistan is puzzling, in particular, we are interested in how these events are reported in Chinese press. In this paper, first, we trace the evolution of the PRC’s official position on Afghanistan, and then, using frame analysis, analyze the coverage of the events of 2021 in the PRC by focusing on three authoritative newspapers, Chinese language versions of “People’s Daily”, “Global Times”, and “The Paper”. Our study demonstrates that the Chinese press supports China’s foreign policy in general and its policy in Afghanistan in particular. Stability in Afghanistan and cooperation with the Taliban (recognized as a terrorist organization and banned in the Russian Federation) on issues of Uighur separatism are important for China’s national security. In the Chinese media, the Taliban (recognized as a terrorist organization and banned in the Russian Federation) are not presented as accomplices of terrorism, which China is fighting within the framework of the Shanghai Cooperation Organization but are described as representatives of the Afghan people who aim to restore the security and stability in the country. When discussing the Taliban (recognized as a terrorist organization and banned in the Russian Federation) takeover in the Chinese media, the focus is often not on the crimes of the new regime - repression, abuse of power, restriction of rights, but on shortcoming of the US policy. The latter reflects an important discursive practice in the Chinese media, “othering” the United States.

Dispersion-strengthened composite materials belong to the group of promising structural materials characterised by a diverse combination of properties. The paper considers examples of the creation and heat treatment of composite materials based on aluminium alloys strengthened by the titanium carbide dispersed phase characterised by high hardness, elastic modulus, and good melt wettability. At present, self-propagating high-temperature synthesis (SHS) is the most accessible, inexpensive and effective way to obtain them. The authors substantiate the expediency and show their successful experience of the formation in the composition of the AMg2 and AMg6 industrial alloys of a titanium carbide dispersed phase with a particle size of 130 nm in an amount of up to 10 wt. % using the SHS method, which makes it possible to increase the hardness of the alloys. Additional heating of the AMg2–10%TiC and AMg6–10%TiC samples after synthesis also contributes to the further increase in hardness. The complex of studies of physical, mechanical and operational characteristics presented in the paper was carried out to compare the properties of the work-hardened matrix alloys and the samples of composite materials before and after heating. The test results showed that heat treatment reduces the porosity of the composites and significantly increases their hardness and microhardness. A slight decrease in compressive strength at a significant increase in wear resistance is observed. It was found that composite materials are characterised by high corrosion resistance to carbon dioxide and hydrogen sulfide corrosion corresponding to the level of matrix alloys. The results obtained allow recommending the developed materials for the production of parts of the connecting rod and piston group, bearings and other wear-resistant parts of friction units.

The main goal of this paper is to contribute to an overall understanding of the phenomenon of globalisation of higher education. Given that in our country the globalisation of higher education has been approached without attempting to provide a more comprehensive definition of the phenomenon, in the first part of the paper, the basic elements and domains that provide the basis for a more complete definition of the globalisation of higher education will be listed and a difference will be made in relation to similar phenomena, such as internationalisation and Europeanisation. Apart from a more comprehensive understanding of globalisation by pointing out its epistemological foundations in the papers from the end of the 20th century, which the domestic scientific public did not pay enough attention to, the paper also provides an overview of approaches to the study of the impact of globalisation on higher education, both the initial ones, which were developed by international organisations, and the academic ones, which enabled a deeper and more comprehensive understanding of the phenomenon of globalisation of higher education. By contributing to a more comprehensive definition of the observed phenomenon, in this paper we intend to contribute to a broader understanding of the phenomenon of globalisation relative to the current view in which globalisation is understood as a modern phenomenon and its impact on higher education is observed after a certain period in which it supposedly arises. The paper affirms the claim that globalisation is just a new name for a phenomenon that has existed in modern civilisation for much longer than the end of the 20th century, and the expansion of higher education contributed to its genesis.

The aim of this paper is to analyze the concept and model of parental involvement in the research on students’ educational achievement. The concept of parental involvement arose in the field of educational policies of the English-speaking countries and market-oriented education systems. Research has shown that different forms of parental involvement have significant effects on school learning outcomes. The Coleman Report in the US and the policy of “educational parentocracy” in the UK significantly stimulated research in this area. The review of the relevant literature confirms the multidimensionalityof the concept of parental involvement which includes parental support for school learning at home and at school, as well as structural and relational aspects. The paper presents two most prominent models of parental involvement in children’s education – the model of overlapping spheres of influence and the so-called DNA or dual navigation model. In the concluding section of the paper, the authors state that the existing conceptualizations and models of parental involvement include different types of parental activities, which is important for the creation and evaluation of school programs of parental involvement. As a consequence of the dominance of the Anglo-American conceptual and research framework, on the one hand, an interdisciplinary approach in the field of research on parental involvement in children’s education is highlighted. On the other hand, an authentic pedagogical view of the goals and effects of parental involvement in education as a subject of study of autonomous science in the tradition of continental Europe has been neglected. It is expected that future research will reaffirm those aspects of education that make it precisely “educational”. Relying on pedagogical principles and goals of education in building family-school relationships is a missing link in the existing agenda of global education policy.

The goal of this paper is to determine the degree and direction of the correlation between the self-evaluation of the fifth-grade elementary school students and their success in the classroom. The paper presents the results of the research on students’ self-evaluation and their success in the classroom obtained on a sample of 208 fifth-grade elementary school students from the territory of the city of Banja Luka. An assessment scale was used for the purposes of the research and knowledge tests for the school subjects Serbian Language and Science and Social Studies were prepared. In line with the character of the research, the method of theoretical analysis and synthesis, the survey research method, and the analytical-descriptive method were applied. The results obtained using the Pearson Correlation Coefficient confirmed that students’ self-evaluation is significantly related to their general success at the end of the first term of the fifth grade of elementary school, their success at the end of the first semester in the subjects Serbian Language and Science and Social Studies, and achievements on the knowledge tests for the same school subjects. The obtained results indicate the importance of introducing student self-evaluation in the educational process in the field of achieving better results at school. However, the fact that self-evaluation is not sufficiently represented in our schools is a downside of this research, indicating a need for additional study and research of student self-evaluation, followed by its systematic introduction into educational practice.

This paper is focused on the means of transforming Trinity Sunday and attempts to “reinvent” this festival into the Russian Birch festival. In late 50s of the 20th century in a burst of the anticlerical campaign, the Soviet festival committees were concerned with creating new secular rituals, and anti-religious analogues of festivals, which would be able to get rid of ingrained “popular Orthodoxy”. The modes of performing the meaningful core of Trinity Sunday are a subject of this research, and theatrical and methodological scenario-based experience in holding the Russian Birch festival is an object. This research is based on numerous methodological guidelines, scenarios, reviews, and transcripts of relevant committees, which made it possible to shed light on complicated processes of generating a new festival. This paper represents the way, in which heroic and plot and compositional framework of original Trinity Sunday was being substituted. This research results in the following: in spite of the anticlerical position being declared, which had constituted the basis for the substitution of Trinity Sunday for the Russian Birch festival, in fact, the newly “invented” festival duplicated the basic functions and elements of the trinitarian concept and was within the framework of Trinity Sunday in terms of archetype. Moreover, the association with commemoration of the dead appropriate to Trinity was reflected in a cult of a heroic death of a soldier of the Soviet Army and updating of other cultural agendas.

Hydrocephalus is a central nervous system disorder which most commonly affects infants and toddlers. It starts as an abnormal build-up of cerebrospinal fluid in the ventricular system of the brain. Hence, early diagnosis becomes vital, which may be performed by Computed Tomography (CT), one of the most effective diagnostic methods for diagnosing Hydrocephalus (CT), where the enlarged ventricular system becomes apparent. However, most disease progression assessments rely on the radiologist's evaluation and physical measures, which are subjective, time-consuming, and inaccurate. This paper develops an automatic prediction utilizing the H-detect framework for enhanced accurate hydrocephalus prediction. This paper uses a pre-processing step to normalize the input image and remove unwanted noises, which can help extract valuable features easily. The feature extraction is done by segmenting the image based on edge detection using triangular fuzzy rules. Thereby, the exact information on the nature of CSF inside the brain is highlighted. These segmented images are saved and again given to the CatBoost algorithm. The Categorical feature processing allows for quicker training. When necessary, the overfitting detector will stop model training and thus efficiently predicts Hydrocephalus. The outcomes demonstrate that the new H-detect strategy outperforms the traditional approaches.

The paper deals with the history of academic commentary in the Soviet era, particularly the formation of standards for a description of the sources of the text, its creative history, and clarification of the encountered realities incomprehensible to the reader. A separate part of the paper is devoted to the critical editions of Russian “classics” designed for high school institutions, among them, e. g., the five-volume collection of works by A.S. Pushkin, issued by Lev I. Polivanov. The main specificity of these comments is that they precede the literary text and answer questions that students may have in advance. The next object of our analysis is N.L. Brodsky’s commentary on Pushkin’s novel “Eugene Onegin,” intended for secondary school teachers. It became a subject of sharp criticism by V.V. Nabokov, like a commentary on the same novel released by Yu.M. Lotman. A new stage in the genre of commentary has become the Russian version of Nabokov’s “A Novel in Verse by Alexandr Pushkin,” growing into an autobiography and a self-discovery tool for the editor (Nabokov). We are also considering the question of how fair was Nabokov’s criticism of the commentaries of Brodsky and Chizhevsky. Another type of commentary should be that of Odessa researcher S.Z. Lushchik, published as an appendix to Kataev’s novel “Werther has already been written” (1980) and entitled “A real commentary on the novel.” This type of commentary grows into a full-fledged study that discovers unknown and carefully hidden details of the famous Soviet writer’s biography.

Law as a special kind of ideal being, generates its own system of ideas and meanings, the verbal representation of which involves not only directly nominative linguistic units, but also semantic tropes, namely, metaphor. Metaphor is a little-studied linguistic phenomenon in legal science, whose functioning in the language of law is denied by many researchers. However, metaphor is an integral component of the nature of law, realized in its various sources. Stemmed from the deep structures of language, metaphor allows appealing to a priori ideas of law of metaphysical level, not subject to rational argumentation, which becomes an integral part of the legal system, making the legal text understandable and accessible to the recipient. The relevance of the chosen topic is conditioned by the necessity to study the metaphorical meanings of legal language at the stage of creating law and interpreting legal realities. For this end the author uses the methods of semantic analysis, and, in general, raises interest in metaphor and metaphorical model in modern science, as well as functioning of metaphor in the legal space. The novelty of the idea underlying the paper lies in applying metaphorical models for legal texts interpretation. Therefore, the aim of this paper is to prove that metaphorical mechanisms are not alien to the language of law; metaphorical model is one of the most productive in the process of semantization of ideas of law. In the light of the above, application of linguistic tools, primarily, the methods of semantic analysis, to the study of legal language and the language of law, in particular, is relevant. Modern methodological tools of linguistics are able to supplement the traditional methods of legal argumentation and interpretation, actualizing their form and content. The main methods of the research are the linguistic-legal method, logical-linguistic method, methods of historical, contextual and motivational analysis. Frequency and universality of the mechanism of metaphorical modelling for the language of law, actualize new functions of metaphor.

The paper examines the issues of bringing controlling persons to subsidiary liability for the obligations of a company excluded from the Unified State Register of Legal Entities. The article determines the judicial procedure for holding controlling persons accountable for claims of creditors. It analyzes the provisions of Russian legislation and judicial practice regarding the grounds for prosecution under paragraph 3.1 Article 3 of the Law on Limited Liability Companies.The research reveals the effect of this rule of law over time and it essence, which excludes the use of the construction of limited liability of participants in a business company. An overview of the legal positions of the Constitutional Court of the Russian Federation on the issues under consideration including the circle of responsible persons, distribution of burden and circumstances of evidence is provided. The paper distinguishes characteristics of good faith and reasonable behavior of creditors and controlling persons as well as legal presumptions corresponding to the circumstance of the case. The conclusion is formulated on the recognition of subsidiary liability by inheritance of debts of a corporate organization. The paper investigates the competence of the court considering disputes on bringing to subsidiary liability of persons controlling a corporation and distinguishes between the corporate (under the general rules of litigation) and bankruptcy (under the rules of class action) proceedings. The characteristics of the powers of creditors acting in the interests of their civil law community are given. The research allows to ensure uniformity of judicial practice at interpreting the applicable rules of law.

This paper provides data on cases of atypical nesting by the Oriental Turtle Dove Streptopelia orientalis in niches of abandoned stone and brick buildings in Primorsky Krai. This phenomenon was only recorded first in 2019, and during a survey of abandoned military bases in the southwestern part of Primorye, it was found out that nesting in the niches of the walls of abandoned barracks is not an isolated case but is quite widespread here. We found nine similar nests, including incubation of eggs and fledging of nestlings. Apparently, the Oriental Turtle Dove is currently at the next stage of synanthropization. The paper also discusses the modes of synanthropization of other representatives of the Columbidae family.

This paper discusses some observations and conclusions made by Astolphe de Custine, a French traveler and writer, during the summer months he spent in Russia in 1839. He traveled a lot around Russia and visited not only the largest cities of the empire but also the provinces. There are quite a few works about de Custine and his book Russia in 1839 in Russian historiography. However, it is important to pay attention not only to his generalized judgments about Russia but also to the specific details that are included in his famous book. The book contains few sketches of Russian provincial life, but a lot of road impressions of Custine’s travels in the Russian provinces. The road tradition encompasses the conditions, circumstances and situations that accompanied the long-distance overland movement. This topic is located at the intersection of historical knowledge, anthropology, and ethnography. It is connected with the social dimension of daily life. The road tradition of Russia attracted close attention of foreign travelers, who voluntarily or involuntarily compared it with their native road circumstances and situations to which they were more accustomed. Custine noticed the peculiarities of traffic and carriages, road improvement, scenes on suburban highways, and much more. The material reviewed and commented on in this paper makes it possible to clarify Custine’s attitude to the road tradition of Russia. It would be wrong to assume that he did nothing more than criticized the Russian provincial road infrastructure. Some of his observations are quite accurate, which is confirmed by other historical sources, and therefore are of interest to us now. However, in the case of a parallel road between St Petersburg and Moscow, which allegedly existed for the convenience of the Russian tsar, he turned out to be mistaken. In that instance, Custine’s habit of moralizing, shining with his thoughts and formulations on various occasions, played a mean trick on him.

This paper aims to highlight the prevalent challenges faced by Hong Kong Chinese students in utilizing connectives and ensuring coherence in their English academic writing. Research indicates that constructing fluent, effective, and cohesive English written texts that maintain logical flow poses a significant challenge for Chinese learners studying English as a foreign language (EFL). This difficulty is likely attributed to the substantial cultural differences between the English and Chinese languages, regardless of the learners’ grasp of English grammar and vocabulary usage. In order to raise awareness among EFL teachers regarding the struggles Chinese students encounter in mastering connectives and cohesion in English writing, this qualitative study analyses five sample English term papers written by Hong Kong university students majoring in English in 2023. The findings reveal that the Hong Kong EFL participants tend to present their arguments in an indirect and circular manner within their English essay assignments. Additionally, due to cultural norms and politeness, the true intent of their writing is often withheld, and the thesis statement is implicitly inferred towards the end of the essay rather than being explicitly stated at the beginning in the introduction. Furthermore, a focus group interview with the student participants conducted after the written analysis demonstrated that their English academic essays reflect the influence of Chinese social interaction norms on rhetorical patterns. The relevance of this study lies in its potential to inform EFL instruction, enabling educators to better support Hong Kong Chinese students in navigating the complexities of English academic writing and to adapt pedagogical approaches that bridge cultural and linguistic gaps.

The information about main results on geometry of developable surfaces with an edge of regression which have a directrix ellipse in the base is gathered. These surfaces constitute a group called “Ruled surfaces of conical type on elliptical base”. This group includes elliptical cones, torses with two ellipses defined in the parallel planes, equal slope surfaces, and ruled surfaces with the main frame of three superellipses that are ellipses in one coordinate plane and broken straight lines in the other two coordinate planes. The paper presents a method for developing torses onto a plane, approximation of torses by folded surfaces, and parabolic ending of a thin sheet from elastic material into a torse shell. A brief review of the methods of stress-strain and buckling analysis of the considered ruled shells is given, including the displacement-based finite element method and variational energy method. It is shown that analytical methods can be used only in the case of applying the momentless shell theory for ruled thin shells of conical type. The analytical formulae for determining the normal and tangent internal forces in any momentless conic shell with a superellipse in the base are derived. References to forty four scientific articles of other authors, working or having worked on the subject of the paper are given. These references confirm the conclusions of the author and the perspectives of investigations of the considered ruled surfaces and shells.

The research deals with linguistic and extralinguistic features of the internationalization process of multimedia products text materials. The term internationalization is considered in the paper within the framework of the translation activity “GILT processes” (processes of globalization, internationalization, localization and translation). The article describes the current state of linguistic and translatological studies of the internationalization process. The paper presents the definition of the internationalization concept. The range of procedures carried out in the process of internationalization is defined. The paper describes the most significant technical procedures performed on the product during internationalization. The paper provides some characteristic linguistic transformations caused by the tasks of internationalization. The research paper offers several examples of using internationalization in the video game industry, the film industry and in creating multilingual and global versions of websites. As a result of the conducted research, two directions of internationalization were identified: pre-localization and global ones. The pre-localization direction of internationalization is to create an intermediate version of the product (mainly in English), which serves to simplify localization (following internationalization) into other languages. This approach significantly reduces the cost of creating a multilingual version of the product. The global direction of internationalization is to create a global version of this product in English. It is assumed that users of the global version can be not only native English speakers, but also those who speak it as a foreign language. Due to the wide spread of English as a foreign language in the world, the creation of an internationalized English version of the product allows companies to enter the global market with significantly lower financial costs and in a shorter timeframe than in the case of creating a multilingual version of the same product.

The article examines the notion of drama as a genre category in European and ancient Indian theatrical theory. The analysis of ancient texts, foremost the treatise of the Nāṭyaśāstra, which can be considered the most authoritative primary source for the study of classical Indian poetics, forms the basis of the research. This paper identifies Sanskrit analogues of such fundamental concepts of Western literary theory as “drama,” “genre,” “performance,” “scenicism,” “literariness,” etc. The closest analogical to European definitions of drama and genre Sanskrit notions are investigated in depth. They are primarely nāṭya and prayoga — two terms used to define various performative aspects of the play. Another notion studied in the paper is rūpa, which originally stood for “scenario” and, later on, for textual and literary format of the staged play. Due to its universality, the same term functioned as the general definition of ten “exemplary” spectacular forms. Finally, the category of vṛtti is discussed, employed in the Nāṭyaśāstra for the characterization of stylistic features of early mysterial performances and, later on, of classical Sanskrit plays. The scope of the paper does not limit itself to bringing to light and discussing these various notions. The ultimate goal is to highlight the differences between Eastern and Western poetological systems and to point out fundamental issues arising from the non-critical use of European terminology when interpreting and investigating ancient Indian aesthetics.

In this paper, the problems with the reconstruction of an affricate phoneme *Ä and its reflexes in Hungarian are discussed. Proto-Ugric *Ä is often reconstructed, but its alleged reflexes in Hungarian show unexplained variation (s, z, cs), and many of the etymologies involve other phonological irregularities. It is troubling that although in some cases Hungarian shows s and Khanty and Mansi *Ä, often the reflexes of the affricate show discrepancy, with part of the languages showing regular reflexes of Proto-Uralic *Å. In this paper, the Ugric etymologies suggested in earlier etymological sources are analyzed and new solutions to the problem of Proto-Ugric *Ä and its reflexes in Hungarian are suggested. The problems is also related to the study of the reflexes of Proto-Uralic *Ä in Hungarian.

This paper analyze the nuanced relationship between corporate income tax (CIT ) rate reductions as a tax incentive and foreign direct investments (FDI) across the Western Balkan countries. Additionally, it examines the extent to which they have progressed with their achievements during two decades (2000-2022). The transition of the Western Balkans from a closed and controlled economy to an open market economy has been challenging, but despite this, they have implemented certain policies to compete in the global market. For instance, they have reduced tax rates and offered tax incentives to attract foreign investors. This has had the effect of lowering the average tax rate, specifically in the year 2000, the average tax rate in corporate income tax was around 17%, while in 2023 the average tax rate in corporate income tax is 11%, or 6% lower. However, despite taking measures, the expected results have not been achieved. Privatization of public enterprises has been one of the main investments that these countries have attracted. The paper addresses the problems that have led to poor results and the inability of countries to convince investors for larger investments. In Kosovo, the issue of progress in this area is being overlooked by the government. It is important for Kosovo to recognize that neighboring countries are making significant progress, and therefore, it is critical to conduct research that not only highlights the current situation but also identifies potential solutions for the future.

Metaphor has been established and extensively examined as one of the tools experts deploy to explain, simplify and transform complex scientific discourse into the knowledge suitable for the audience of non-experts. However, relatively little research has been conducted on metaphor scenario (Musolff 2006, 2016a) and its role in this process. Therefore, in this paper we explore how metaphor scenario is used to explain Covid-19 vaccines’ safety and effectiveness to the population in an understandable manner in order to speed up the immunization process in Serbia. By analysing a data set gathered from various Serbian electronic news media sources ( NovaS , N1 , Danas , Vreme , Večernje novosti , Mondo , Politika , Telegraf , Krug ) published from January to December 2021, we aim to explore (1) how the three metaphor scenarios, combat, container and movement, may help simplify complex scientific concepts in the pro-vaccine discourse; and (2) how the conceptual elements of these scenarios and their interconnected relations are used for this purpose. The findings showed that these conventional scenarios manifest their explanatory potential by means of several sub-scenarios, whose conceptual elements establish useful mappings relying on rarely used components of source domains. The results confirm that metaphor scenarios may be used strategically by medical experts as an apt explanatory tool to simplify challengingly complex scientific concepts to the general public. The paper contributes to current research on the role that metaphor and other cognitive instruments play in science popularization.

As the geopolitical situation changes, it is necessary to discuss how politics is structured by metaphor in the context of recent social phenomena, such as the European migrant crisis. This paper analyses the conceptual metaphors politics as war, politics as a game, politics as a trade, and politics as a theater in British and Bosnian-Herzegovinian newspapers. The goal of this study is to establish to what extent and in which situations journalists resort to figurative language to persuade the recipients to view politics in a desired way. The paper aims to reflect on the use of deliberate metaphor as a perspective-changing device by journalists striving to achieve their rhetorical goals and influence recipients’ perception of the political situation. The corpus comprises 174 British and 307 Bosnian-Herzegovinian articles collected from August 2015 to March 2016 (247,912 words). Relying on Steen et al.’s (2010) model of metaphor analysis, the paper investigates the types of metaphor in the corpus, the deliberate use of politics metaphors and their communicative function in migration discourse - discussing both the rhetorical goals of journalists and the rhetorical effects on recipients. It has been established that the analyzed set of metaphors has a divertive and persuasive function in migration discourse. Similar studies are encouraged to shed light on how deliberate metaphors related to politics may have diverging communicative functions in other types of discourse.

Cognitive linguistic investigations into the metaphorical conceptualization of anger suggest that languages are remarkably similar on a schematic level, with intensity and control as two, possibly universal dimensions underlying the metaphorical conceptualization of anger. These dimensions, however, can manifest themselves in language-specific metaphors. Yet arriving at a definitive answer to the question of universality versus variation is hindered by (a) a relatively limited number of systematic, contrastive analyses; and (b) varied methodologies, with some papers adopting a type-based account, while others following a token-based analysis. We take up both challenges in the present paper with the aim of offering a more definitive answer to the question of the universality and variation of anger metaphors. We investigate the anger metaphors of a type-based analysis, focusing on dictionary data of anger-related idioms, and a token-based analysis, focusing on data collected from online corpora, in three languages: (American) English (2,000 random instances of the lemma anger from the Corpus of Contemporary American English), Hungarian (1,000 instances of the lemma düh from the Hungarian National Corpus) and Russian (1,000 instances of the lemma gnev from the Russian National Corpus). The lexical data were analyzed with the well-established Metaphor Identification Procedure (MIP). Our results indicate that there is a great deal of congruence relative to shared metaphors in both approaches, but this derives from specific-level metaphors in the lexical approach, whereas it derives from more schematic, generic-level metaphors in the corpus-based approach. The study shows that the full picture of the metaphorical conceptualization of a complex emotion concept such as anger can only emerge with the combination of the type- and token-based approach.

Most papers written on polysemy focus on sense overlaps and lexical ambiguity, yet studies that explore the possibility of establishing a polysemic complex and explaining how the new interpretations arise through metaphor are almost non-existent in Arabic. This paper aims to explore how metaphor serves to create new concepts as part of polysemic complexes through adopting Dynamic Conceptual Semantics. The target words are bidʒannin [make mad][1] in Jordanian Arabic (JA) and mad in American English (AE). An online questionnaire containing 15 items was sent to forty participants (20 JA speakers and 20 AE speakers) where they were asked to provide the interpretations of the words bidʒannin and mad in contextualized sentences. The AE contextualized instances of mad were collected from Corpus of Contemporary American English (COCA) which generated 5,168 tokens of mad (in the years 2015/2019). The questionnaire results were discussed in a semi-structured focus-group discussion involving 10 participants. We have demonstrated that when an expression is deemed suitable for all situations categorized under both the primary perspective of madness and a related perspective involving exaggerated descriptions of entities, a concept (P) emerges that bears similarity or relevance to the polysemic complex ( bidʒannin\mad ) to which the expression belongs. In such cases, we can consider the related perspective (P') as a member of the polysemic complex ( bidʒannin\mad ). Thus, this study explains how the same metaphor can lead to a complex of multiple meanings in two different languages that are not necessarily related to each other.

The perestroika-time public discussion about the “white spots” of history in the Kaliningrad region focused on the history of East Prussia, which had previously been under a tacit ban. This article analyzes publications about the pre-war past of the region in the popular youth newspaper “Kaliningradskiy komsomolets” from 1985-1991. It examines the process of changing the regional historical narrative and characterizes the transformation of the historical memory of Kaliningrad residents during the years of perestroika. The paper aims to trace how the “discovery” of East Prussian themes occurred, who promoted the new historical narrative and by what means, and the stages through which the process of “appropriation” of the cultural heritage inherited after the war by the inhabitants of the region went. The study utilized a qualitative-quantitative content analysis method of newspaper texts, conducted with the help of the MAX QDA 2020 program. The results were interpreted using the categories of “Our Own” and “the Other” from B. Wandelfels’ philosophical concept and P. Nora’s “place of memory” one. The paper concludes that by the early 1990s, Kaliningrad society had varied approaches to the “pre-Soviet” period ranging from denial of the significance of the “foreign” and “the Other” heritage to its full acceptance as “one’s own”. The analysis of the content of the publications, including the commemorative practices reflected in the newspaper, shows that the regional historical narrative changed during the years of perestroika. The course of “exorcising the Prussian spirit”, approved immediately after the war, although not completely eradicated, became a marginal phenomenon, while the study, preservation, and utilization of the experience and historical and cultural heritage of the predecessors became the dominant trend in which the press of the glasnost’ era played a significant role.

The Multi-skilled Resource Constrained Project Scheduling Problem (MS-RCPSP) is a complex and multi-faceted problem that involves scheduling activities whilst considering various resource constraints. These constraints include limited availability of workers, equipment, and materials, with each activity requiring a minimal set of skills to be executed. Furthermore, for a better resemblance to reality, workers/machines are assumed to be multi-skilled/multi-purpose posing another dimension of complexity to the problem. The objective is to minimize project duration, cost, or other relevant criteria while accounting for the inherent resources flexibility. This paper provides a systematic review of the literature pertaining to MS-RCPSP, and an in-depth analysis of 171 papers published between 2000 and 2021 inclusive. The conducted bibliometric analysis identifies the top contributing authors, most influential papers, existing research tendencies, and thematic research topics within the field. In addition, this review highlights different aspects of the MS-RCPSP, spanning the significance of performance measures, solution approaches, application areas, and the incorporation of time constraints. While project completion time, cost, and tardiness are common performance indicators, other measures such as multi-skilled staff assignment and schedule robustness are also deemed important. Although various methods have been employed to solve the MS-RCPSP including exact and approximate approaches, the selection of the most-suited approach depends on the problem’s scale, complexity, and constraints, necessitating careful consideration of each method’s strengths and weaknesses. Interestingly, several studies have jointly addressed resource and time constraints in the context of MS-RCPSP, often considering tardiness, and have proposed different algorithms, models, and metaheuristics to tackle these challenges. This paper clearly highlights research gaps and promising avenues for future research. This work provides valuable insights for project managers to effectively schedule tasks in the presence of multiple flexible resources.

Study of RNA-protein interactions and identification of RNA targets are among the key aspects of under-standing RNA biology. Currently, various methods are available to investigate these interactions with, RNA immunoprecipitation (RIP) being the most common. The search for RNA targets has largely been conducted using antibodies to an endogenous protein or to GFP-tag directly. Having to be dependent on the expression level of the target protein and having to spend time selecting highly specific antibodies make immunoprecipitation complicated. Expression of the GFP-fused protein can lead to cytotoxicity and, consequently, to improper recognition or degradation of the chimeric protein. Over the past few years, multifunctional tags have been developed. SNAP-tag and HaloTag allow the target protein to be studied from different perspectives. Labeling of the fusion protein with custom-made fluorescent dyes makes it possible to study protein expression and to localize it in the cell or the whole organism. A high-affinity substrate has been created to allow covalent binding by chimeric proteins, minimizing protein loss during protein isolation. In this paper, a HaloTag-based method, which we called Halo-RPD (HaloTag RNA PullDown), is presented. The proposed protocol uses plants with stable fusion protein expression and Magne® HaloTag® magnetic beads to capture RNA-protein complexes directly from the cytoplasmic lysate of transgenic Arabidopsis thaliana plants. The key stages described in the paper are as follows: (1) preparation of the magnetic beads; (2) tissue homogenization and collection of control samples; (3) precipitation and wash of RNA-protein complexes; (4) evaluation of protein binding efficiency; (5) RNA isolation; (6) analysis of the RNA obtained. Recommendations for better NGS assay designs are provided.

The paper considers the problems of macroparameter control in a linear dynamic system. In the authors’ previous paper, such problems in controlling nonlinear systems were investigated. Variations of the considered functionals and necessary optimality conditions were obtained. This paper focuses on the trajectory beam control in the linear case. In this case, the problem of beam control can be reduced to the problem of the individual trajectory control. The developed approach may be of interest in the study of charged particle dynamics in accelerating and focusing structures, as well as in the construction of the velocity field in automatic image processing.

In this paper, we derive sharp asymptotics for the spectral data (eigenvalues and weight numbers) of the fourth-order linear differential equation with a distribution coefficient and three types of separated boundary conditions. Our methods rely on the recent results concerning regularization and asymptotic analysis for higher-order differential operators with distribution coefficients. The results of this paper have applications to the theory of inverse spectral problems as well as a separate significance.

Let $N\Phi(K)$ be the nil-triangular subalgebra of the Chevalley algebra over an associative commutative ring $K$ with the identity associated with a root system $\Phi$. This paper studies the well-known problem of describing automorphisms of Lie algebras and rings $N\Phi(K)$. Automorphisms of the Lie algebra $N\Phi(K)$ under restrictions $K=2K=3K$ on ring $K$ are described by Y. Cao, D. Jiang, J. Wang (2007). When passing from algebras to Lie rings, the group of automorphisms expands. Thus, the subgroup of central automorphisms is extended, i.e. acting modulo the center, ring automorphisms induced by automorphisms of the main ring are added. For the type $A_{n}$, a description of automorphisms of Lie rings $N\Phi(K)$ over $K$ was obtained by V.M. Levchuk (1983). Automorphisms of the Lie ring $N\Phi(K)$ are described by V.M. Levchuk (1990) for type $D_4$ over $K$, and for other types by A.V. Litavrin (2017), excluding types $G_2$ and $F_4$. In this paper we describe automorphisms of a nil-triangular Lie ring of type $G_2$ over an integrity domain $K$ under the following restrictions on $K$: either $K=2K=3K$, or $3K = 0$. To study automorphisms, the upper and lower central series described in this paper, are essentially used.

There is some evidence that in certain cases a contact of rough elastic solids is multiply connected, i.e. have regions in it where contact surfaces are apart from each other and the contact pressure is zero. The issue of the connectivity in rough elastic contacts has both theoretical and practical interest, especially for seals. In this paper, we extend the earlier conducted analysis of rough contacts without coatings in plane and axially symmetric formulations on the cases of plane and axially symmetric rough elastic contacts with special coatings and compare our findings. The main goal of the paper is to obtain the exact analytical solutions of plane and axially symmetric rough elastic contacts with a special coating and analyze their properties such as contact connectivity and contact pressure smoothness compared to the smoothness of the surface roughness profile. This goal is achieved by using solution expansions in Chebyshev and Legendre orthogonal polynomials. A range of contact parameters has been determined for which the contacts are connected individually.

Introduction. The sustainability of territories of urban settlements (USs) and rural settlements (RSs) is one of the priority tasks of urban planning and socio-economic planning, and is also determined by the goal of integrated development of the territory. This issue is widely discussed in the scientific and technical literature, where the focus is on socio-economic, environmental and anthropogenic factors that characterize the urban system, which are used to obtain a quantitative indicator of the level of sustainability using entropy-weighted, (TOPSIS-Technique of Preference Similarity to the Ideal Solution) and other methods. At the same time, the importance of cultural heritage in sustainable development has not received enough attention. This paper presents the results of sustainability assessment of the impact of immovable tangible cultural heritage of eight Syrian cities based on a multi-criteria model.Materials and methods. The paper uses materials from open sources and statistical data of municipal organizations, the selection of which is based on the Sustainable Development Goals (SDGs) and the system approach. The data include characteristics of social, historical-cultural, economic, environmental, engineering, transport subsystems of the city. The aim of the study is to determine a generalized index characterizing the sustainability of the city and the impact of its factors on its importance of cultural heritage in promoting socio-economic development and urban reconstruction after the military conflict.Results. Based on the presented model, calculations of the urban sustainability index (IS) of 8 Syrian cities — Damascus, Homs, Aleppo, Latakia, Palmyra, Daraa, Deir ez-Zor and Idlib for the period of 2010 (before the military conflict) and 2023 were performed, which showed a decrease in the sustainability index up to two times. This is due to the destruction of residential areas of engineering and transport systems, destruction of cultural heritage objects. It is also found that tangible cultural heritage has a great impact on the sustainability of the city system.Conclusions. The proposed model for determining the index of urban sustainability (IS) allows us to obtain a quantitative assessment and analyze the impact of each factor. It is shown that along with the restoration of residential areas and objects of engineering and transport infrastructure, it is necessary to carry out works to preserve objects of cultural heritage, the loss of which leads to a decrease in the sustainability of the city, the loss of its urban identity.

Hybrid power supply systems (HPSSs) are considered as a good option for electric power supply of remotely located from the grid consumers due to significant fuel savings compared to diesel sets. Quick development and improvement of HPSSs may be achieved using specialized methodologies and programs. In the paper a schematic diagram is proposed and operation principles of a 400 V / 50 Hz HPSS were developed. The system’s main component is the master generating unit of the hydropower plant using a 250 kW induction generator (IG). The voltage of the system is controlled by the controller of the AC/DC power converter. The electrical frequency of the system is controlled by the speed controller of the hydropower turbine. A wind turbine, an energy storage system and a regulated dump load are connected to the IG through the AC/DC converter. Goal. The paper aims to develop a methodology for steady state performance analysis of the hydraulic turbine driven isolated IG operating in parallel through an AC/DC power converter with additional sources and consumers of active power. Methodology. The methodology for evaluation of performance characteristics of the IG operating in the proposed system has been developed. The methodology is based on the equivalent circuit of the system, equations of active and reactive power balance in the system and the superposition method. Results. The equations of frequency, voltage and power regulators of the system are given. The performance characteristics of the IG operating in the system supplying resistive and RL load in «constant voltage – constant frequency» mode are obtained. Novelty. The developed methodology is innovative in taking into account the control algorithms of the system. The comparative analysis of the IG’s performance operating in the stand-alone generating unit and in the generating unit connected to the proposed system is performed. Practical value. The developed methodology can be used for development and performance improvement of hybrid AC power systems.

The paper reviews Suzanne Kord's 2023 book dedicated to the film “The Cabin in the Woods.” It analyzes the film's meta-nature through allusions and references. The review explores philosophical themes addressed in the movie, including the clash between faith and nihilism, the ethical implications of self-sacrifice, humanity's place in the world, the individual versus humanity, and the issue of free will. It highlights the film's extradiegetic elements, emphasizing how “The Cabin in the Woods,” as a philosophical text, elicits a philosophical response from viewers. The paper presents Suzanne Kord's horror theory, which posits that the essence of the genre lies not in fear but in guilt. It offers an assessment and brief critique of this theory.
