A Estética da hibridação e a literatura gerada por computadores: um estudo do software Alexandrins au greffoir
Authors: Carvalho Pereira Vinícius
Published: August 2024

No universo da cybercultura, a imbricação entre tecnologia e arte é cada vez mais intensa, de modo que a técnica deixa de ser instrumento para concepção da obra e se torna, ela também parte da obra. Tal hibridação é o mote estético do software gerador de poemas Alexandrins au greffoir. O presente artigo analisa como a lógica da hibridação e do fluxo constituem uma poética desse software e dos poemas por ele produzidos. Nesse sentido, são colocados em discussão também os processos de escrita e leitura no universo da literatura gerada por computadores, o que, em última instância, questiona como ler parte significativa da literaura na pós-modernidade.
Escenarios en miniatura: los artefactos fotonarrativos de Óscar Esquivias y Asís G. Ayerbe
Authors: Venzon Ruben
Published: August 2024

En la actualidad son cada vez más frecuentes las formas de expresión literaria que combinan palabra y fotografía sobre un mismo soporte. Se supera de este modo la concepción obsoleta de la imagen como simple ilustración de un texto previo. Dentro del panorama editorial español, destaca la colaboración entre el escritor Óscar Esquivias y el fotógrafo Asís G. Ayerbe, coautores de una serie de obras miniaturizadas. Para ejemplificar los mecanismos subyacentes en dicha práctica intermedial y valorar su alcance estético, el presente artículo analiza sus artefactos fotonarrativos más sobresalientes: En el secreto Alcázar (2008), secretos xxs (2008) y Calle Vitoria (2015). En estos microdispositivos, la confluencia de dos sistemas semióticos amplía sensorialmente la experiencia lectora y enriquece las posibilidades de la minificción.
GRADIENTS IN THE EVOLUTION OF RUSSIA’S MULTIREGIONAL SYSTEM
Authors: СУСПИЦЫН С.А.
Published: August 2024

Проанализированы особенности пространственного развития экономики РФ в 2000-2020 гг. В целом территориальная структура экономики страны мало изменилась, а удельный вес ее азиатской части даже сократился. Показано, что сводные характеристики экономики обладают признаками макроструктурного равновесия в некоторых метриках, что во многом обусловлено особенностями макроэкономической политики в стране. Развитие регионов и их локальных объединений такими признаками не обладает. Рассмотрены перспективные изменения пространственной структуры РФ в рамках трех возможных направлений: концепции социального государства, предложенной А.Г. Аганбегяном; комплекса мер новой экономической политики (НЭП-2); селективной эволюции многорегиональной системы страны на базе обобщения лучших региональных практик. С использованием когнитивной модели проанализированы роль, место и функции каждого участника системы «регионы - федеральный центр - бизнес-структуры» как по отдельности, так и в локальных связках: «федеральный центр - бизнес-структуры», «бизнес-структуры - регионы», «регионы - федеральный центр». Особое внимание уделено анализу возможностей равновесного распределения компетенций и ресурсов развития между регионами и федеральным центром и сформулированы условия обеспечения таких возможностей.

This study examines the spatial development of the Russian economy from 2000 to 2020. Besides minor changes, the territorial structure of the economy remained stable, with a decrease observed in the Asian region’s share. Our analysis reveals indicators suggesting macrostructural equilibrium in certain metrics, largely influenced by macroeconomic policies. However, regional development and local associations do not exhibit similar equilibrium traits. We explore potential shifts in the spatial structure of the Russian Federation across three avenues: the concept of a social state by A.G. Aganbegyan, initiatives under the New Economic Policy (NEP-2), and the selective evolution of the multiregional system based on the best regional practices. Using a cognitive model, we scrutinize the roles, positions, and functions of each participant in the “regions - federal center - business structures " system, both independently and within local alliances: “federal center - business structures," “business structures - regions," and “regions - federal center. " We pay particular attention to analyzing the possibilities of distributing competencies and development resources equitably between regions and the federal center, along with outlining the conditions necessary to achieve such balance.
MULTILEVEL POSITIONING OF AGRARIAN-TERRITORIAL SYSTEMS
Authors: БАЙДАКОВ А.Н. , ЗВЯГИНЦЕВА О.С.
Published: August 2024

В статье исследуются природно-социально-экономические объекты - АПК и сельские территории в составе единой системы. Практическая реализация системного подхода позволила представить указанные объекты как системообразующие компоненты аграрно-территориальных систем (АТС) с тремя ключевыми подсистемами: природной, социальной, экономической. Целью работы выступило многоуровневое стратифицированное позиционирование АТС регионов России. Гипотеза исследования состоит в установлении возможности определения общих паттернов развития для групп разнородных аграрно-территориальных образований на основе их многоуровневого позиционирования. В основе полученных результатов лежит использование методов системного анализа и многомерной статистики, что позволило подтвердить справедливость выдвинутой гипотезы. Основным результатом является реализованная методика многоуровневого позиционирования региональных АТС с учетом внутрикластерного и межкластерного соотношений их ключевых подсистем (экономической, социальной, природной). Данный подход позволил выделить общие паттерны развития АТС регионов России. Результаты могут быть использованы при разработке и актуализации предметно и объектно дифференцированных программ развития аграрно-территориальных систем.

This article delves into the examination of natural, social and economic objects, specifically focusing on the agro-industrial complex and rural areas as parts of a single framework. Through the practical application of a systemic approach, we argue for considering these objects as integral components shaping agrarian-territorial systems (ATS), comprising three primary subsystems: natural, social, and economic. The objective is to stratify and position the ATS of Russian regions across multiple levels. The study hypothesizes that determining common developmental patterns among groups of heterogeneous agrarian-territorial formations is feasible through multilevel positioning. Results, derived from system analysis and multidimensional statistics, validate this hypothesis. The main outcome is an implemented method for multilevel positioning of regional ATS, accounting for intra-cluster and inter-cluster ratios of their key subsystems (economic, social, natural). This methodology makes it possible to identify general developmental patterns within Russia’s agrarian-territorial systems, offering insights applicable to the formulation and revision of subject- and object-differentiated ATS development programs.
The orphic poem about stones ("Lithica")
Authors: Alexandrova Tatiana
Published: August 2024

The paper represents a literary translation of the late ancient poem “Lithica” (“On stones”). Scholars date the poem by the period from 2nd to 4th centuries. Along with the “Orphic Argonautica” the “Litica” is a part of the Orphic corpus. From the point of view of the genre it is a lapidary in verse (a literary work about stones, mostly precious and unusual). Lapidaries were very popular in the epoch of late antiquity and Middle age. The author of the “Litica” borrows his knowledge from different sources; his work has intersections with the works of Theophrastus, Pliny the Elder, Galenus, Dioscorides and with the prosaic lapidaries of different times. Stories about the stones are located into the double narrative frame: these is a bucolic plot, in which the narrator on the way to the temple meets the “divine man” Theodamas who tells him about some stones. In the middle of the narration Theodamas inserts in his own story the one of the diviner Helenus (this fact should be evidence of the deep antiquity of the information given in the poem). The main content of the poem is information about approximately 30 different minerals, their useful proprieties as therapeutic, so magic; in the commentaries are given the modern hypotheses of their identification. The information about the stones in the poem is given unevenly; from the simple mention up to the detailed story including medical or magic recipes and mythological digressions connected with the origin of each stone. As well as the “Orphic Argonautica” the ”Litica” reflects the decline of ancient rationalism and the domination of the religious interests over the “scientific” ones which is typical for the late ancient mentality.
The first books in Kaunas
Authors: Lūžys Sigitas
Published: August 2024

The article centers on sets of books from Kaunas of the 17th-18th centuries.
The first contacts with books in Kaunas were recorded in the 16th century when the studies of Lithuanian youth in foreign universities began. In the beginning, the inhabitants of Kaunas mainly went to the University of Cracow, so the first book which belonged to Andreae de Cawno, "Questiones de anima," was listed at Cracow University.
From the middle of the 16th century, there is some knowledge about private sets of books in Kaunas. The biggest and most interesting sets of books belonged to Jonas Olandras, Jonas Savecevičius, Tomas Frezas, and Fridrikas Vongerenas. In the library of the latter, there were even works of classical authors (Virgilius, Ovidius, Martialis). The very first known text in Lithuanian in a private library is "Ewangelie polskie i litewskie" by Jonas Jaknavičius, which D. and K. Velt had in 1785.
Monasteries and churches also had their libraries. Four incunabula known in Lithuania at present had belonged to monasteries or monks in Kaunas. It should be noted that at the beginning of the 18th century, among 32 books in St. Cross Church, there were works of famous Lithuanians - Mikalojus Kristupas Radvila, Žygimantas Liauksminas, Kazimieras Vijūkas-Kojalavičius.
The most abundant educational library in Kaunas belonged to the Jesuits. Up to now, in the collection of KAVB, there are 78 books from the Jesuits' library, mainly in Latin, Polish, 2 books in German, and 1 book in French.
After the abolition of the Order of the Jesuits in 1773, the most valuable books were transferred to Vilnius University Library.
In the middle of the 19th century, the remaining books from the Jesuits' library in Kaunas were supplemented by the remainder of the Jesuits' library from Kražiai.

Management of Post-cardiotomy Shock
Authors: Hall Eric J , Papolos Alexander I , Miller P Elliott , Barnett Christopher F , Kenigsberg Benjamin B
Published: August 2024

Patients undergoing cardiac surgery experience significant physiologic derangements that place them at risk for multiple shock phenotypes. Any combination of cardiogenic, obstructive, hemorrhagic, or vasoplegic shock occurs commonly in post-cardiotomy patients. The approach to the diagnosis and management of these shock states has many facets that are distinct compared to non-surgical cardiac intensive care unit patients. Additionally, the approach to and associated outcomes of cardiac arrest in the post-cardiotomy population are uniquely characterized by emergent bedside resternotomy if the circulation is not immediately restored. This review focuses on the unique aspects of the diagnosis and management of post-cardiotomy shock.
PHILOSOPHICAL FOUNDATIONS OF DIETRICH VON HILDEBRAND’S VIEWS ON FAMILY AND MARRIAGE: VALUES AS SUPERACTUAL KNOWLEDGE
Authors: ZAKHARCHUK Oleksandr
Published: August 2024

The philosophical basis of Dietrich von Hildebrand’s views on conjugal love, family and marriage is considered. In particular, his key epistemological and axiological ideas are analyzed. Dietrich von Hildebrand was a leading philosopher of the realist phenomenological and personalist directions, who worked in all major branches of philosophy, including ethics, metaphysics, epistemology, philosophical anthropology, social philosophy, and aesthetics. Hildebrand’s concept of family and marriage stems from his religious beliefs and philosophical views. To understand the concept of family and marriage, it is necessary to consider it in the context of the epistemological, axiological, phenomenological and personalistic foundations of Hildebrand’s philosophical views. Philosophical searches of Hildebrand are carried out in a certain connection with Catholic theology. It is latently present in his logic, views and beliefs. Hildebrand’s teaching is a constructive attempt to overcome existential pessimism and tragedy, when the awareness of the fragility of life gives rise to the understanding of being as a value. Philosophical searches of Hildebrand are directly related to his religious worldview and act as his rational justification. Epistemology and axiology play a special role in this justification. He paid special attention to superactual knowledge. Hildebrand’s superactual knowledge is directly related to the concept of value. Hildebrand assigns the problem of values ​​and moral values, in particular, a central place in philosophical consciousness. Hildebrand’s epistemological and axiological views, along with his religious beliefs, underlie his views on sexual love, family and marriage. Hildebrand points to the superactual character of such personal attitudes as faith or love and emphasizes the importance of their superactual existence for the meaningfulness and integrity of an individual’s life.
PERSPECTIVES ON VIDEO GAME RESEARCH THROUGH THE CONCEPT OF MEDIA ARCHAEOLOGY
Authors: SKUBINA Nataliia
Published: August 2024

This article delves into various approaches to the cultural and philosophical study of video games. It primarily examines the potential of employing methodological foundations of media archaeology to enhance the understanding of the history of video game technical media. Additionally, it offers a brief review of existing publications on the proposed topic.To justify the applicability of the media-archaeological approach, the article provides a concise analysis of key research directions in game studies, highlighting their advantages and main shortcomings. The paper includes a succinct history of video game research, elucidates the philosophical concepts underpinning early works on the essence of video games, and explores the principal directions within game studies. Special attention is given to several approaches: Espen Aarseth’s narratological perspective, which interprets the cyberspace of games as a text that can be decoded and read; Gonzalo Frasca’s ludological approach, where the primary characteristic of a game is its interactivity; and Ian Bogost’s multi-level theory of video game study, which integrates the use of media anthropology.Subsequently, the article outlines the core principles of media anthropology as an interdisciplinary field that not only investigates the past of media and attempts to forecast the future of technologies by identifying patterns in their development but also addresses the relationship between humans and technologies. The primary representatives of this field, such as Friedrich Kittler, Jussi Parikka, and Erkki Huhtamo, are also mentioned.In the final section of the article, the necessity of employing media anthropology for understanding video games is discussed, particularly emphasizing the hegemony of technical media over the content of video games. Furthermore, examples of the application of the archaeological approach in game studies are provided, illustrating the potential of this direction.This comprehensive exploration aims to advance the discourse on video game studies by integrating insights from media archaeology and media anthropology, thereby fostering a deeper and more nuanced understanding of video games as cultural and technological artifacts.
THE CONTEMPORARY POLITICAL SECURITY ANALYTICS: «ORDINARY» APPROACHES TO THE FORMATION OF PUBLIC EXPERT CONTENT
Authors: TRETYAK Oleksii
Published: August 2024

The article is devoted to the basics of public perception of the political security of the state in the conditions of a full-scale invasion of modern Russia into Ukraine. The purpose of the study is to establish the specifics of the analysis of communication threats to modern political security in the public sphere. The significance of “ordinary” or “everyday” approaches to political-security analysis and production of political-security content is characterized. It was emphasized that the “retrospective approach” or “method of historical analogies” in the situational dimension involves comparing the security message or the security crisis situation as a whole with certain historical events of the past. The behavior of the subjects (actors) of the retrospective analysis, who risk drawing the wrong conclusion and incorrectly reflecting the real world, is analyzed. The principles of commenting on the political and security situation based on taking into account a relatively narrow range of facts and circumstances are revealed. The factors of preparation for various outcomes of the development of events and increased preparedness for unexpected situations have been clarified. The guidelines for fostering a culture of “experimentation” and continuous improvement, which is especially important in the context of expert protection of business processes from potential political threats, are revealed. Security analytics ecosystems and the integration of open data observations have been proven to improve the effectiveness of security analysis. Networked horizontal communication and data sharing “ecosystems” between related non-governmental expert-analytical structures have been found to focus on understanding and using social and organizational networks to identify potential threats and opportunities for cooperation. It is substantiated that in the production of secure analytical content it is important to apply the principles of flexible project management. It was established that the possibilities of increasing the effectiveness of retrospective analytics appear on the basis of the selection of historical analogies according to the parameters of the functional conditions. It was found that analysts try to assess security events from the side of a “distant observer” based on a “backward” approach. It was concluded that an important means of discrediting informational “throws” of the enemy is an asymmetric communication action (action) based on the formation of the agenda.
POLITICAL INTERESTS AND POLITICAL DECISIONS: THE POSSIBILITIES OF FORMING A DEMOCRATIC AGENDA
Authors: KHMELNIKOV Yehor
Published: August 2024

The article is devoted to the study of political interest as a hidden determinant of the activity of associated and non-associated pressure groups (informal lobbying) within the bureaucratic power vertical. Applying modern interdisciplinary methodological tools, the author offers a rationale for the expediency of public articulation of political interests, elimination of hidden lobbying, as well as non-public agreements between the main political players, which slow down the modernization of the institutional environment of the democratic political system. The article reveals and describes the optimal efforts of the Ukrainian political class, which will be aimed at implementing the specified strategic changes. The author reveals an explanation of the functioning of the mechanisms by which interest groups operate and their influence on the formation of the agenda. The crucial importance of interest groups for understanding the dynamics of political decision-making is noted. It is emphasized that group actors are working to bring their issues to the top of the political agenda. The text examines the functionality of providing well-grounded and reasoned information by interested groups that reinforces the importance of their demands. The paper addresses demonstrations, petitions, and social media campaigns as common tactics used to mobilize public opinion and pressure political institutions into action. The article analyzes the pooling of resources and efforts by associated interest groups that purposefully increase the likelihood that their issues will be high on the political agenda. It is noted that publicizing demands and problems can lead to a change in the course and strategy of the current leadership or power team. It has been established that by consistently advocating their cause in public, group actors can ensure consideration of agenda items by politicians and attract media attention. Attention is paid to the cooperation of political forces and interested groups to obtain detailed information and recommendations during the development of draft laws or regulatory acts. Emphasis is placed on the priorities of elected officials who seek to conform to the “mainstream” of public opinion and public sentiment. In the final part of the article, the author emphasizes that the full representation of political interests and the interests of minority groups that are not in the mainstream of public attention. It was concluded that the institutional structure of European democracy is more open to the development of public interests. Therefore, for modern Ukraine, an important element is the formation of structures of political arbitration regarding the conflict of political interests or the provision of this functionality to already existing institutions
THE CORRELATION OF THE INTERPRETATIONS OF THE DEFINITIONS “REGION” AND “REGIONALIZATION” IN THE MODERN SCIENTIFIC DISCOURSE
Authors: HOLOVKO Ivan
Published: August 2024

In the course of the research, the relationship between the definitions of “region” and “regionalization” in modern scientific discourse was established. The conducted research proved that the specified definitions are in a systemic condition, and the relationship between them balances, reflecting the realities, between the change in the tendencies to the formation of regions under the influence of globalization and the reverse impact of glocalization on regionalism as a phenomenon and regionalization as a process, which in turn triggers mechanism of paradiplomacy. The categories “region” and “regionalization” are closely interrelated and condition each other, are complex and ambiguous. The direct relationship between these concepts is due to the fact that regionalization is based on the division of the world into regions and the process of their international cooperation, at a time when regions realize their own ambitions to enter the international arena through the use of paradiplomacy tools. Despite the fact that paradiplomacy creates certain difficulties for central governments, it generally does not lead to an increase in conflicts between the region and the state. Of course, states can look for ways to integrate paradiplomacy into their state diplomatic apparatus and strengthen their role in addressing foreign policy goals. However, if the region is focused on finding ways to separate from its state, this integration may turn out to be practically impossible. The category “region” in modern political science is defined. The paper examines approaches to the interpretation of the definition of “regionalization” in modern scientific discourse.
MODERN COMMUNICATIVE PRACTICES IN INTERNATIONAL RELATIONS: THE CIVILIZATION DIMENSION
Authors: ISHCHENKO Ihor , BASHKEIEVA Olena
Published: August 2024

The article examines the effectiveness of communication practices in modern international relations against the background of civilizational features of the interacting parties. The authors found out the actual state and nature of communications at the international level between the East and the West, they discovered the causes of conflict, and formed a conclusion on this basis. The researchers answered the question - how to reach a new level of effectiveness of communication practices in international relations and how to achieve congruent communications in the intra-societal system? The purpose of the article is to clarify modern effective communication practices taking into account the inter-civilization factor in international relations. The relevance of the article lies in the need to search for new approaches in international communications based on the synergy of communications to solve global problems of our time, create safe living conditions for the world community. As a result of the study, the authors revealed the ineffectiveness of modern communication practices. This statement is true for both international communications and communications in the internal environment of political, intra-societal systems. The subjects of international relations often simply do not take into account the civilizational differences of their partners, therefore they cannot come to an agreement with them on important issues of life, first of all. Among these differences, we should highlight: cultural, ethnic and religious characteristics of communicants - representatives of the East and the West. Modern international conflicts arising on the basis of civilizational and cultural confrontations between the East and the West push us to develop a new paradigm of communication practices. These practices should be based on congruent interaction of communicants, on the elimination of their civilizational and cultural differences as the cause of unsuccessful communications. Politicians are now forced to take into account not only the political, economic and power resources of the interacting parties, but also cultural, religious and ethnic characteristics. The focus of researchers should be on issues that include not only minimizing disagreements and balancing interests between states, but also searching for the broadest possible agenda and identifying common interests at the global and regional levels.
CONCEPTUALIZING THE SUBJECTIVITY OF GLOBAL LEADERSHIP IN CONTEMPORARY INTERNATIONAL RELATIONS THEORY
Authors: CHERKASOV Stanislav , OMELCHENKO Andrii
Published: August 2024

This article, based on an interdisciplinary approach and structural-functional analysis tools, examines the transformation of classical forms of conceptualizing the subjectivity of global leadership in contemporary international relations theory under the influence of new global political realities. It emphasizes that the initial classical positioning of international leadership as the primacy or hegemony of a single state on the international stage is yielding to other political practices that have not yet gained normative consolidation and theoretical conceptualization. It has been identified that modern international processes demonstrate a trend towards the institutionalization of international leadership in the form of a collective subject of international relations, endowed with exceptional powers and special status. New theoretical approaches increasingly note a shift in focus from classical factors ensuring leadership in international relations by enhancing the status and leadership potential of individual actors to the formation of collegial global leadership, including the concept of global governance, which is increasingly seen as the most probable and conventionally interpreted prognostic model for the transformation of the modern world order. Contemporary international relations theory identifies several subjects of international relations, with the nation-state traditionally occupying a leading position. In recent decades, other actors have been added to the list, including international governmental and non-governmental organizations, transnational corporations, civil associations, and private individuals. The emergence of new types of international relations subjects on the international stage, combined with the increasing importance of integration associations and the growing technological potential of digital networks, alongside the practical impossibility of establishing control over them, and the transfer of certain sovereign powers from national states to international institutions, indicates that traditional methods of governance and regulation in world politics are becoming outdated, losing their relevance and effectiveness in contemporary conditions. This necessitates the formation of an institutional foundation appropriate to the modern international system. Increasingly, this foundation of world order is associated with the phenomenon of global leadership. However, attempts to conceptualize it based on classical subjects of international relations are demonstrating increasing methodological inefficiency, leading to the search for new forms of the subjectivity of global leadership on the international stage.
GONAD MATURITY LEVELS OF LEMPUK FISH (Gobiopterus sp) IN RANU GRATI, PASURUAN, EAST JAVA
Authors: Anitasari Septi , Yanuhar Uun , Faqih Abd Rahem , Sanoesi Ellana , Susilowati Surya Rachman , Sansi Delfina Husniya
Published: August 2024

Pasuruan Regency in East Java Province boasts a natural lake, Ranu Grati, formed by volcanic activity, covering about 50 hectares and home to endemic species like the Lempuk fish (Gobiopterus sp.). These fish play a crucial role in Ranu Grati's trophic structure, serving as primary consumers and key planktonic organisms supporting higher trophic levels. The Lempuk fish population faces sustainability challenges due to high demand for this traditional food, leading to overexploitation and decreased reproductive capabilities. Understanding the reproductive biology, particularly gonad maturity levels, is vital for effective resource management. This study, conducted from June to August 2023, aimed to investigate the reproductive biology and gonad maturity levels of Lempuk fish in Ranu Grati. Analysis revealed a male-biased sex ratio, with significant fluctuations in gonad maturity levels across months. In June, the sex ratio was 1.05, in July 1.17, and in August 1.39, indicating a higher population of males. Histological observations showed asynchronous egg development, likely influenced by environmental factors and the fish's reproductive strategy
Microalgae as a potential feedstock for biodiesel production in the Philippines: A review
Authors: Nortez Kendrick Bantillan , Arguelles Eldrin De Los Reyes
Published: August 2024

Organic sources of biodiesel, such as microalgae are considered nowadays as potential renewable energy resource. In contrast to higher plants, microalgae have fast growth rate, high photosynthetic efficiency, high biomass productivities, as well as high O2 production and CO2 fixation rate. These organisms can be cultivated using accelerated technologies like open pond and photobioreactors. Extraction of oil and its conversion to methyl esters is of primary importance in biofuel industry. Three well known methods of oil extraction for algal lipids are expellers/press, solvent extraction method and supercritical fluid extraction. These methods are influenced by several operational factors that may have considerable impact on the extraction rate and efficiency. In the Philippines, the current scenario for biodiesel consumption is still expected to increase in the future due to the proposed increase of biodiesel blending as mandated by the Philippine Biofuels Law. Massive research efforts were conducted in search for alternative feedstocks in the Philippines. This led to several studies using third generation feedstock (such as microalgae) for biodiesel production. Based on previous studies, microalgae can be cultivated to engineered systems and is more sustainable (as compared to plants and other microorganisms) since it occupies less land area compared to other feedstocks and it is not consumed as food. Hence, microalgae have the potential as alternative biomass feedstock for a sustainable production of biodiesel in the Philippines with superior quality fuel characteristics.

Published: August 2024

Collagen is a type of protein that is plentiful and has a wide variety of applications. Collagen is often derived from porcine and bovine, however, both sources are considered to transmit disease, particularly porcine sources, which haram to Moslem. There are some methods for collagen extraction, on of them using acid method.  The purpose of this study was to obtain the best method of extraction and analyze collagen from alternative sources, specifically salmon skin, which is abundant. This study included two stages, i.e. pretreatment with sodium hydroxide for eliminating non-collagen proteins prior from salmon skin and extraction with acetic acid for collagen extraction. Pretreatment was carried out utilizing a split-plot design with parameters for determining the levels of non-collagen protein. The extraction step used a factorial completely randomized design to observe yields, amino acids, functional groups, and molecular weights. The results indicated that the extract was collagen. It was indicated by high glycine, alanine, and proline amino acid content. The result of SDS-PAGE showed the extracted was type I collagen was characterized by two identical 1 chains and one similar, but 2 different chains. The propeptides of type I procollagen have a similar composition. The most effective method for eliminating non-collagen proteins prior to extracting collagen from salmon skin was pretreatment with a 0.05 M NaOH solution for 10 hours.  Collagen extraction using acetic acid at concentration of 0.5 M for 48 hours resulted in a yield of 12.79%.

Construction of block diagrams of a simulation model of the customer service process
Authors: Ganenko Olga , Gorozhanina Evgeniya
Published: August 2024

The article, which is part of the author’s dissertation research, is devoted to the construction of a simulation model, namely a discrete-event model of the customer service process «as is» and «as will be».
The introduction substantiates the relevance of the research topic, highlighting the object and subject of the study. A hierarchical structure of the system of quality indicators for infocommunication services has been constructed. There are 4 levels of indicators, at each level quality indicators are highlighted, namely: service speed indicators (average service time for a technical fault, average response time for reference services); satisfaction indicators (percentage of calls regarding technical aspects of service, percentage of calls regarding organizational aspects of service) and others. A hypothesis has been put forward about a change in the state of the service process after the introduction of a functional dialog agent into the process, which involves a reduction in customer service time.
To test the hypothesis about reducing customer service time, discrete-event simulation models of the process «as is» and «as will be» were built, since modeling in terms of queuing theory not only improves the understanding of existing processes in the company, but also helps to identify bottlenecks and identify areas for further optimization, which ultimately leads to increased customer satisfaction and the efficiency of the company as a whole.
Within the framework of the developed discrete-event model, the main attention is paid to two main stages: modeling the receipt of requests and modeling the processing of requests. Process optimization includes the introduction of an automated diagnostic system, namely a functional conversational agent to reduce wait time and increase request processing throughput.
Block diagrams of discrete-event simulation models of the service process were also constructed in terms of the AnyLogic environment, and the advantages of its use were highlighted.

Authors: Elatife Khalid , El Marjani Abdellatif
Published: August 2024

This study presents a numerical investigation into the influence of rotor blade geometry on the performance
of oscillating water column (OWC) impulse turbines for wave energy conversion. A numerical model was developed and validated using experimental data for both circular and elliptical rotor profiles. Simulations were conducted for inhalation and exhalation modes of turbine operation, focusing on flow angles, flow coefficients, and losses coefficients in various turbine components. Results reveal
significant differences in performance and flow behavior between turbines with circular and elliptical blade profiles, particularly in the inhalation mode. Circular blade profiles demonstrated superior performance and favorable flow characteristics, whereas elliptical profiles exhibited more pronounced flow separation attributed to higher curvature variation. The findings underscore the critical role of blade profile in determining turbine performance, highlighting the importance of optimizing blade
design for enhanced efficiency. Building upon these results, an integration of an intelligent control system for guide vane geometric angles is proposed to ensure optimal alignment with downstream flow angles throughout the cycle. This study contributes to the understanding of turbine performance in OWC systems and provides insights for future design optimization efforts aimed at maximizing energy conversion efficiency.

İskitler, Sakalar, Sarmatlar ve Massagetler, adları tarihî kaynaklarda geçen en erken Avrasya bozkır halklarındandır. Bu halklar hakkındaki bilgilerin çoğu, Antik Yunan ve Romalı yazarlar tarafından oluşturulan kaynaklarda bulunmaktadır. Hērodotos, Strabōn, Hippokratēs, Thoukydidēs, Platōn, Hēsiodos, Khoirilos, Aiskhylos, Loukianos, Yaşlı Plinius ile Ammianus Marcellinus gibi Yunan-Roma yazarları, söz konusu halkların konargöçer ve hayvancı yaşam tarzı hakkında ayrıntılı betimlemeler vermişlerdir. Ancak bu kaynaklarda bozkır konargöçerliğiyle ilgili önyargılı ifadelerin ve abartmaların olduğu da görülmektedir. Bu makalede söz konusu kaynaklarda erken bozkır konargöçerliğiyle ilgili kayıtlar incelenmiştir.
Educational Attitudes of Parents and Their Ideas about Conflicts with Children of Younger Adolescence

Published: August 2024

The purpose of the study was to identify the relationship between the educational attitudes of parents and their perception of the conflict of relationships with younger adolescents. The study involved 72 parents of younger adolescents, in an equal ratio of fathers and mothers. For the study of educational attitudes, the questionnaire “Parental Attitude Research Instrument” (PARI) by E.S. Schaefer & R.Q. Bell (adapted by T.V. Neshcheret) was used. The peculiarities of parents’ ideas about conflicts with adolescent children were revealed using a developed questionnaire concerning certain private issues of the course of conflicts in the families of respondents with their children. It was found that the emotional distance of parents with simultaneous concentration on the child is combined with the frequent occurrence of conflicts with younger adolescents. Parents who are the first to contact a child after a conflict, unlike parents who expect initiative from a teenager, suppress the child less and have better emotional contact with him. Most parents focus on the destructive impact of conflicts on their relationships with their children. Those parents who analyze conflict situations with children and find more constructive impact of the conflict on their relationships, maintain a balance of suppressing the child and giving him freedom, concern for his safety and trust in the child, and also try to exercise rigor in a dosed manner, control irritability and maintain emotional involvement in relationships with children. These data confirm the assumption that there is a connection between the attitude of parents to the child and the frequency of conflicts with him, an assessment of the impact of conflicts on the nature of child-parent relations.

The 2022 Ms 6.9 Qinghai Menyuan, China, earthquake is the most destructive earthquake to have occurred near the Lenglongling fault at the western segment of the Qilian–Haiyuan fault since 2016 Ms 6.4 Menyuan earthquake. The 2022 earthquake generated surface rupture measuring about 30 km with an unexpected maximum offset larger than 2.6 m in the epicentral area, and severely damaged the local infrastructure and transportation. To analyze the possible causes of the large surface slip and to reveal the rupture process, we modeled the dynamic rupture and strong ground motion of the 2022 Menyuan earthquake using the curved-grid finite-difference method. In the simulation, the geometry of the fault is constructed based on the observed trace of the surface ruptures. The background tectonic stress field is assumed to be uniform, and the slip-weakening law with the constant friction coefficients is adopted. Our modeling results showed that the rupture model with a focal depth of 6 km and a rupture width of 10 km provides a good fit to the observed surface slips and the field records. We also investigated the effects of the focal depth and the rupture size on the surface slips. It is found that under the same conditions, the dynamic rupture models with a larger rupture size generated greater coseismic slips at the surface. However, only the model with a relatively smaller rupture width produced an Mw∼6.7 event similar to the Menyuan earthquake. In contrast, the influence of the focal depth is less significant. The decrease of the focal depth only leads to a slight increase in surface slip. Our results illustrated that a surface-breaking rupture with a relatively narrow width may physically control the general characteristics of the earthquake. This study provides a new insight into the rupture dynamics of the 2022 Menyuan earthquake.
Between Utopia and Civil Disobedience. The Question of Violence in Edward Abramowski’s Social and Political Thought
Authors: Gniadek Michał
Published: August 2024

The article attempts to examine the problem of violence in Edward Abramowski’s socio-political thought from the perspective of two concepts: utopian thinking, which, according to Karl Popper, inevitably leads to violence, and civil disobedience or an act of resistance to authority that rejects violence in principle. The first part of the article shows how Abramowski’s critique of utopianism shapes his vision of a world devoid of violence, realised step by step through grassroots institutions. The second part, then, is devoted to ‘collective conspiracy against the government’, which, as one of the ways of practising his utopia, allows the struggle for national liberation. Ultimately, it seems that the rejection of violence puts Abramowski closer to piecemeal engineering than to a utopian one, while his social vision fits into Popper’s concept of open society.
