Issues discussed in the article related to determining the influence of mechanical activation in a rotary high-speed mixer of cement-water compositions and solutions based on them. Relevant for this study is the activation of cement in combination with the consumption of ground quartz sand (S = 250 m2/kg), the amount of which was adjusted in the range from 0 to 40 % of the cement mass. The use of this technology, along with reducing cement consumption, ensures acceleration of the processes of cement hydration and intensification of exothermic heating of the hardening composition. Mechanical activation is also reflected in the acceleration of the loss of mobility of cement-water compositions filled with ground sand. The presented experimental data made it possible to evaluate the influence of the activation times (90 and 180 sec) of the binder on the diameter of the spread of the aqueous cement-containing composition. It has been established that the main contribution (up to 90 % of the total value) to the decrease in the water-binder ratio (provided that equal-viscosity compositions are obtained) is achieved when the cement-containing composition is activated for 90 seconds. Subsequent activation of the binder (up to 180 sec) has a slight effect on the growth of the diameter of the composition spread and does not exceed 5-10 %. The exothermia of the hardening cement-water composition determined by the thermos method indicates a significant influence of mechanical activation both on the kinetics and on the achievement of the maximum temperature of its heating. The introduction of ground sand does not change the overall picture of the effect of mechanical activation on exothermic heating, changing only the decrease in intensity and the decrease in maximum heating of the cement-water composition. The influence of mechanical-chemical activation of Portland cement with the addition of quartz sand on the strength of a 1:1 mortar at 3 and 7 days of age was revealed. Experimental studies indicate a positive effect of binder activation on the compressive strength of the mortar. The increase in strength of samples using mechanically activated cement reached 15-25 % compared to the control.

The article is devoted to the study of the impact of artificial intelligence (AI) on modern education, the analysis of the prospects for the use of artificial intelligence in institutions of higher education (HEIs) and the resulting problems. It was emphasized that the future of education is inextricably linked with the development of information and communication technologies and intelligent machines. The prospects of artificial intelligence open up new opportunities in teaching and learning in higher education institutions with a strong potential to change even the management system of higher education institutions. The history of the emergence of artificial intelligence is briefly given, starting from the 13th century, when Raimund Lullius proposed the idea of implementing reasoning and mental processes in an intellectual machine. The article uses methods of complex theoretical and descriptive analysis. The scientific novelty of the work: the established effectiveness of using artificial intelligence in education can be presented in the form of the following functions: automation, integration, acclimatization, differentiation, identification. The increasingly widespread use of artificial intelligence in higher education institutions and schools also raises ethical questions. Educational institutions must now consider what type of data is collected, how that information is used, and what controls are in place to protect the privacy of learners. Practical significance of the work: in addition to functions that reflect the effectiveness of using artificial intelligence in the educational process, because the authors identified the positive aspects of introducing artificial intelligence into education. The results of the study: the authors of the article come to the conclusion that now it is necessary to rethink the function and pedagogical models of learning in connection with artificial intelligence in higher education institutions, because significant opportunities are opening up for higher education institutions thanks to the use of artificial intelligence in the educational process.

The article reveals the concept of the pedagogical culture of higher education institution teachers. It is emphasized that effective pedagogical activity depends on the personal, psychological, and professional characteristics of the teacher. In this regard, the requirements for higher education institution teachers have been determined. The article describes pedagogical practice as a highly important element in the system of scientific and pedagogical personnel training. As a result of the analysis of scientific sources, a definition of professional and pedagogical culture was given. Pedagogical culture is a harmony of highly developed pedagogical thinking, knowledge, feelings and professional creative activity, which contributes to the effective organization of the pedagogical process. The main components of the pedagogical culture of higher education institutions teachers are characterized: culture of pedagogical thinking, spiritual and moral culture, culture of communication. Pedagogical thinking means a special style of professional thinking of a teacher, which is realized in intellectual and practical activity and leads to effective work of the educational process. The spiritual and moral culture of a teacher is an integral system of personal and professional qualities of an individual, such as spirituality, moral awareness, professional ethics, which contribute to the active professional activity of a teacher with the aim of forming moral qualities in students. As for the third component, there is no doubt that the main task of pedagogical communication is establishing, establishing and maintaining relationships with colleagues and students. And the nature of the teacher's relationship with those with whom he is forced to come into contact during the performance of his professional activity directly affects its success and effectiveness. It was concluded that all the considered aspects of pedagogical activity are equally important and the underestimation of any of them can lead to undesirable results.

Published: July 2024

Interest in lanthanum-strontium ferrite ceramics having mixed electron and oxygen-ion conductivity as well as good stability is due to the great potential for use as electrode materials for solid oxide fuel cells. The article presents the results of an assessment of alterations in the morphology and phase composition of ceramics based on lanthanum-strontium ferrite compounds obtained by solid-phase synthesis. This was done during simulation of conditions as close as possible to their operating conditions in the mode of elevated temperatures. The primary objective of the research is to alter theratio of the phase composition of ceramics under prolonged thermal exposure, simulating thermal ageing processes, and thus, oxidation processes that occur during long-term cyclic tests. The studies revealed that the presence of the Sr2Fe2O5 phase in the composition of ceramics results in enhanced resistance to corrosive oxidation processes during high-temperature corrosion. The data obtained on the change in the electrochemical characteristics of ceramics depending on the exposure time during the simulation of high-temperature degradation revealed that the most significant decreases were observed after 400-500 hours of consecutive tests at a temperature of 500-600 °C and after 250-300 hours at temperatures above 700 °C. Moreover, the reduction in the specific power is due to the formation of oxide inclusions in ceramics, resulting from the decomposition of the (La0.3Sr0.7)FeO4 phase in the composition of the ceramics. In turn, the presence of the Sr2Fe2O5 phase results in the formation of an oxidation-resistant structure, leading to less pronounced changes in specific power during measurement of parameters of electrochemical characteristics.

Published: July 2024

The correct operation of heat exchange equipment has a direct impact on the quality of the products produced. The study of critical factors impeding the stable operation of equipment at petrochemical enterprises and the elimination of the main ones are of paramount importance. The primary challenge in the operation of heat exchange equipment is the quality of circulating water, which serves as the primary coolant. The analysis of circulating water and scale from an industrial site by the method of atomic emission spectrometry with inductively coupled plasma was performed, which made it possible to identify bottlenecks that impede the operation of the equipment. Scaling and the corrosive effects of water are the most detrimental. Furthermore, a methodology was devised to ascertain the elemental composition of solid deposits derived from heat exchange equipment. The malfunction of heat exchange equipment can give rise to significant issues in production. To prevent emergency production shutdowns, the authors of the article consider a method for improving the quality of circulating water by using the latest reagent, which can reduce the corrosive effect and reduce salt deposition inside heat exchangers. The proposed inhibitor offers a number of advantages, including a reduction in the environmental impact and high work efficiency.
Simulating the reservoir pressure maintenance strategy by injecting HC and non-HC gases into the Achimov reservoirs

Published: July 2024

Prerequisites for the study are selection of the optimal agent to maintain reservoir pressure and setting the optimal conditions under which the maximum condensate recovery factor is achieved.

   The aim of the article is to assess the technological efficiency of methods for increasing condensate recovery while maintaining reservoir pressure by injecting hydrocarbon (methane) and non-hydrocarbon (nitrogen, carbon dioxide) gases.

   The subject of this study is the Ach3-4 reservoir within the Novo-Urengoyskoye license area of the Urengoy field. The most effective methodology for identifying the stated issue is the outcome of hydrodynamic calculations conducted on a composite hydrodynamic model implemented in ECLIPSE 300 format. In order to model one of the sections of the Ach3-4 reservoir, a development element was selected in which the average parameters corresponded to those of the full-scale model. The efficiency of the selected methods was evaluated by comparing them with the baseline scenario, which represents the conventional approach to the development of the Ach3-4 reservoir on depletion. The injection start was set in a dynamic model after removal of 30, 50 and 85 % of gas initially in-place and at a steady pressure of 18, 37 and 40 MPa, provided that gas recovery factor was achieved on depletion. The technological efficiency of the development options was evaluated by examining the dynamics of the condensate recovery factor in relation to the dynamics of the gas recovery factor. The optimal option was identified based on the maximum value of the condensate recovery factor. The results of the studies conducted to increase condensate recovery from reservoirs indicate the effectiveness of using carbon dioxide as an agent. The condensate recovery factor depends on the ratio of injection and production wells, the time of the start of reservoir pressure maintenance and the number of pore volumes pumped. The efficiency of carbon dioxide injection at late stages of development increases dramatically when the minimum mixing pressure is reached.
Polymorphisms of the myostatin gene in animals (overreview)
Authors: Klimanova E. A. , Alexandrova D. A. , Kochnev N. N.
Published: July 2024

A review of publications is presented on the diversity of myostatin gene polymorphisms in farm animals. The quality indicators of animal carcasses largely depend on many factors, of which the genotype of the individual plays an important role. Myostatin (MSTN), or growth/differentiation factor 8 (GDF-8), is a protein member of the transforming growth factor (TGF-β) superfamily. The MSTN protein sequence includes a secretion signal sequence, a proteolytic processing site, and a carboxy-terminal region with a conserved pattern of nine cysteine residues. The main function of myostatin is to inhibit the growth of muscle fibers. Myostatin regulates muscle development at key moments in the intrauterine development process: proliferation of muscle precursors, proliferation and differentiation of myoblasts. Myostatin expression is most intense in skeletal muscle tissue. Many farm animals have mutations associated with decreased myostatin activity, of which the most pronounced example is double muscle in some beef cattle breeds. In general, mutations in the myostatin gene lead to a qualitative and quantitative increase in muscle mass in meat breeds of farm animals, as well as changes in other characteristics that depend on muscle mass, such as running speed in dogs and horses. The negative consequences of mutations in the myostatin gene include cancer, premature aging, dystrophy, etc., to prevent which heterozygotes are usually given preference in selection.

In selection and breeding work with cattle for dairy productivity, it is important to select the best individuals and their effective use in populations. The purpose of the study was to study the origin, genealogical affiliation, genotype and breeding value of sires from which cows with record productivity were obtained. The study was carried out on 15 sires fathers of 20 record-breaking cows of the black and white breed of breeding farms in the Vologda region. Based on the results of studying the origin of bulls from which cows with record productivity were obtained, it was found that out of 15 sires, 9 bulls were imported and 6 were obtained from breeding farms of the Russian Federation. Four bulls born in Russian breeding farms have one or both parents of foreign origin.

The majority (14) of the record-breaking fathers have from 94% to 100% Holstein blood in their genotype and belong to the genealogical lines of the Holstein selection. The genetic potential of the sires was realized by recordbreaking daughters by 101.9% 176.7%. Based on the results of calculating the selection differential, it was established that all bulls had a positive effect on the milk productivity of the studied offspring. Their daughters are superior in milk yield for the highest lactation of their mothers from 1052 kg to 9222 kg of milk. The study of the breeding value of bulls obtained from the results of a centralized assessment using the BLUP method showed that 12 out of 15 studied bulls fathers of record cows are improvers in terms of milk productivity. The study showed the significant contribution of foreign genetics to the production of highly productive animals in domestic herds. As a result of many years of breeding work, animals with high productivity potential have been created, which must be used to obtain competitive domestic breeding material.

Published: July 2024

Paraffin deposition is a serious flow assurance issue faced by the Petroleum industry which can be mitigated by different techniques among which chemical treatment is the most practical solution to reduce the pour point and improve the cold flow properties of crude oil. However, the utilization of environmentally hazardous chemicals for mitigation of this severe issue also causes additional threats. Thus, motivated by such a problem, current research endeavor to synthesize and application of ecofriendly products for the mitigation of paraffin deposition. Cashew nut shell liquid (CNSL) collected from cashew nut shells was esterified with ethanol amine. The CNSL derivative (CD) was tested as a pour point depressant and cold flow improver for paraffinic crude oils. The pour point of doped crude oil was significantly reduced reaching a maximum of 120C and viscosity was tremendously dropped up to 90%. CD demonstrated remarkable paraffin inhibition efficacy of up to 56%. Photomicrographs of treated crude oil were inspected, revealing changes to the wax shape and microstructure. Thus, CNSL can be utilized as a flow improver for waxy crude oil and it has potential as a renewable chemical feedstock for the manufacturing of pour point depressants and other oilfield chemicals.
Recognition of Religious Qualification in the Russian Federation: Legal Aspect
Authors: Гусев Андрей
Published: July 2024

В статье предлагается анализ развития проблематики признания квалификаций, связанных с выполнением функций служителей и религиозного персонала, в российском праве. Эта проблематика была введена в юридическое поле в начале 1990-х годов, когда образовательной деятельности религиозных организаций был усвоен статус образовательной деятельности, подлежащей государственному лицензированию. Следующим шагом стало предоставление в 2008 году духовным учебным заведениям права реализовывать образовательные программы высшего образования и получать по ним государственную аккредитацию. Это сделало возможным осуществление подготовки служителей и религиозного персонала в рамках программ высшего образования. Завершающий на сегодня этап включал признание теологии в качестве научной специальности в 2015 году и последующее выстраивание связи данной специальности с конфессиями. Сложившаяся в Российской Федерации модель, однако, имеет ограничения и не обеспечивает признания религиозных квалификаций лиц, обучавшихся в духовных учебных заведениях до получения ими права проходить государственную аккредитацию либо получивших богословские степени до создания научной специальности «теология». В заключении статьи даётся оценка значимости проекта федерального закона N 323220-8, который в случае его принятия позволит обеспечить признание религиозных квалификаций в тех случаях, в которых сегодня такое признание невозможно.

The article analyzes how the problem of recognition of qualifications related to the performance of the functions of clergy and religious personnel evolved in Russian law. This problematic was first introduced into the legal field in the early 1990s, when the educational activity of religious organizations were given the status of educational activity subject to state licensing. The next step was the granting in 2008 to religious educational institutions of the right to carry out educational programs of higher education and receive state accreditation for them. This made it possible to prepare clergy and religious personnel through higher educational programs. The final stage to date included the recognition of theology as a scientific discipline in 2015 and the subsequent linking of this discipline with confessions. However, the existing model in the Russian Federation has limitations and does not provide recognition of religious qualifications of those who studied in theological educational institutions before they received the right to receive state accreditation or who obtained theological degrees within the system of religious education before the creation of the scientific discipline "Theology". The article concludes by assessing the significance of the draft federal law N 323220-8, which, if passed, would allow for the recognition of religious qualifications in cases where such recognition is not possible today.

Behavioral functions of octopamine in adult insects under stressful conditions
Authors: Mezheritskiy M. I. , Vorontsov D. D. , Dyakonova V. E. , Zakharov I. S.
Published: July 2024

Octopamine (OA) functions as a neurotransmitter, neuromodulator, and neurohormone in the insect body. Octopaminergic neurons were found in the nervous system of all studied insect species. OA acts on nerve, muscle, glandular and fat cells through receptors associated with G-proteins, preparing and providing intense physical activity. The concentration of octopamine in the hemolymph increases in response to a wide range of stressful factors, from infection to physical activity, which is consistent with the well-known idea of OA as a “stress hormone” in insects. However, for more than 10 years there has been no analysis of publications on the modulating role of octopamine in connection with various types of complex behavior in insects, including stressful conditions. The current data suggest that the activity of the octopaminergic system is associated with adaptation to physical activity, modulation of aggressive behavior in a situation of intraspecific conflict, avoidance behavior when meeting a predator, feeding and search behavior in conditions of hunger. It is concluded that octopamine at different levels (from modulation of neural ensembles and receptors to energy metabolism) is involved in providing adaptive responses of insects to a wide range of stressful situations.
Peculiarities of use of generative artificial intelligence in codes of academic integrity in higher education institutions of Singapore
Authors: Shchedrina Mariia
Published: July 2024

As of 2024, there are six institutions of higher education in Singapore. The article presents the results of an analysis of the academic integrity policies of all six Singapore universities in the context of using artificial intelligence (AI) in education. The trend towards updating institutional policies of higher educational institutions in Singapore is driven by high academic standards and strict requirements for ensuring the quality of higher education in the country, as evidenced by international rankings of the best higher educational establishments. In addition, educational institutions in Singapore actively invest in scientific research and technological innovations, leading to the dynamic implementation of AI technologies in teaching and learning processes, which requires an update of institutional policies. Therefore, the articleaimed to highlight the features of academic integrity norms and recommendations for usinggenerative AI in Singapore's higher education context. The analysis highlighted various approaches to academic integrity and plagiarism issues, as well as showed a trend towards adaptation to modern technologies, including AI, in their policies. It is worth noting that the institutional policies of Singapore universities regarding the use of generative AI set a trend not only topenalize unauthorized use but also toserve as a source of support and assistance to students and teachers in effectivelyusing these technologies. These features reflect the general trend towards increased regulation and control in using new technologies in the academic environment, emphasizing the importance of academic integrity in moderneducation. Along with this, there is a need to prepare scientific and pedagogical personnel for the ethical use of AI technologies to understand the needs of the modern generation of students and adapt to the pedagogical challenges associated with the rapid development of digital technologies and AI tools. The highlighted features may be useful for Ukrainian universities in the process of developing institutional policies for regulating the use of generative AI in education.

Authors: Porkuian Olha , Halhash Ruslan , Chankotadze Yana
Published: July 2024

Universities displaced by the war in Ukraine are addressing both the immediate challenges of resuming their full-fledged educational and research activities and laying the foundation for their own development models. The experience of relocation and recovery gained by displaced universities is important for understanding their sustainability potential and for developing public policy and further strategies for the development of higher education in Ukraine. Researchers pay much attention to the impact of the war on higher education in Ukraine, the problems of organizing the activities of displaced universities, their restoration and strategic development. Today, displaced universities continue to build their own new model of development. Modern challenges have necessitated the search for new opportunities to overcome the crisis in society, to study the role and place of universities in regional development and the post-war economic recovery of Ukraine. Today, there are scientific and practical publications that summarise the current issues of the functioning and development of higher education in general and displaced HEIs in particular. However, the existing cases and practices require more thorough research and generalisation, which would be useful for both theorists and practitioners of higher education management. Such research should focus on the formation of signs of sustainability, adaptability, self-organisation and development of the higher education system in times of crisis. The purpose of the publication is to highlight the problems and challenges faced by the displaced universities, to assess the experience and achievements in responding to these challenges, and to describe the approaches taken to update and implement the university development strategy and anti-crisis measures during the relocation. The publication also attempts to outline the main solutions that are already being implemented, tasks and activities for the future, which are being developed by the community of displaced universities to restore the university's activities and its transition to a qualitatively new level already during the relocation and in the postwar period. In addition, the publication aims to highlight the experience of organizing cooperation between displaced universities in implementing international projects to restore their activities.

Microplastics are a new pollutant that has become a global problem and requires treatment as soon as possible. Microplastics are plastic waste that degrades into small particles measuring <5 mm. Until now, microplastics have not only been found in the environment but also in drinking water. Based on the results of field studies, it is known that drinking water refills at drinking water depots (DAM) are an alternative option used by the people of the Sumbersari sub-district to meet their drinking water needs. This paper examines the presence of microplastics in refillable drinking water, including the characteristics, concentration, and exposure to microplastics in consumers of refillable drinking water. This observational study uses descriptive methods to systematically examine and present facts regarding microplastics and exposure to microplastics in DAM in the Sumbersari sub-district. The research showed that microplastics had contaminated 12 DAM with an average microplastic concentration of 7.1 particles/liter. The forms or types of microplastics found were fibers and fragments with sizes ranging from 0.01 mm to <5 mm and the colors most commonly found were blue, black, red, gray, and transparent. The measurement results also explain that consumers of refillable drinking water will be exposed to microplastics of at least 5.61 particles/liter/day and a maximum of 15.98 particles/liter/day, depending on the amount of drinking water consumed daily.

The history of family law reform in Islamic World can’t be separated from contributions of the thoughts of the Islamic scholars from time to time.  One of them is Nawal el Saadawi's contribution through her criticism of family law in Egypt. This article aims to discuss some of Nawal's criticisms based on two questions. First, what is Nawal el Saadawi's criticism of family law in Egypt? Second, what solution does Nawal offer to realize a family law that - she calls - is just? By answering both of the questions, it is hoped that this study will provide inspiration for academics and legal practitioners in their efforts to find a gender-just family law format. The method used in this research is qualitative with library research, namely by examining library sources that are relevant to the research theme. The results of this research are, first, material in Egyptian family law relating to divorce procedures, polygamy, bait at tho'ah, living and hadhanah, which Nawal considers is still discriminatory towards women. This discrimination occurs because the state ignores patriarchal culture in society. Second, in Nawal's view, efforts to realize just family law must be started from strengthening the principle of freedom of thought among Islamic scholars and legal practitioners.
