Повышение точности получаемых данных, стабильности результатов исследования скважин, улучшение прочностных свойств радиопрозрачного корпуса, и как следствие, повышение ресурса геофизического прибора невозможно без диагностики свойств материала корпуса и оценки уровней нагрузок, способных привести материал к потере несущей способности. Исследовано влияние разных схем циклического нагружения на форму и размеры петли неупругости при испытаниях кольцевых образцов из стеклопластика (0 º‒90 º), изготовленных методом косослойно-продольно-поперечной намотки стеклянного волокна на основе алюмоборосиликатного и магнийалюмоборосиликатного стекла. В результате исследования влияния схем нагружения было показано изменение формы и петли неупругости и переход от релаксационного типа неупругости к неупругости гистерезисного типа из-за накопления остаточных деформаций при изменении угла нагружения с 30 º на 45 º и увеличении амплитуды нагрузки. Результаты разрушения образцов при схемах нагружения аналогичны условиям нагружения в эксплуатации и могут быть использованы для оценки процесса разрушения.
Burnable absorber element (Gd and Er) use in the WWER-type reactor to increase the refueling time
Authors: Rahman A. S.K. , Uvakin M. A. , Hossen M. M. 
Published: April 2024

In a WWER-type pressurized water reactor, high-neutron-absorbing materials can compensate for the excess reactivity. Theoretical and computational analyses were conducted in this article to use burnable absorbers placed in a fuel rod to reduce the reactivity margin for extending refueling time for WWER-type reactors. To investigate the reduction of the reactivity margin, the fuel burnup calculation was performed without a burnable absorber and with a combination of a variety of burnable absorbers, namely natural Gadolinium (Gd) and Erbium (Er), applying a simplified GETERA program. The calculation found that the variation of the quantity of the burnable absorber (Gd, Er) inside the fuel assemblies governs the reactivity margin for the fuel burnup and increases the efficiency of Uranium fuel (UO2). The combined use of Gd and Er leads to a smoother decrease in reactor reactivity due to a smaller Er absorption cross section, which makes it possible to reduce the total mass of Gd in the fuel element and reduce the blocking effect. In the calculation, Gd concentrations employed in the computation at 1.5% and 3%, while Er concentrations were used within the range of 0.1%–0.6%.

The process of integrating foreign musical religious culture into the practice of Russian neo-Pentecostal churches is analyzed, an overview of the creativity and styles of Russian artists and musical groups is given.
The aesthetic component of the revolution in the context of the aesthetics of history
Authors: Savelyeva A. B. 
Published: April 2024

The author of the article raises the question of the aesthetic content of the real historical process. The article examines history as a dramatic space of human development, as a locus and topos of the manifestation of his creative abilities, as a process that can be studied and described in the categories of classical aesthetics. According to the author, the objective course of history itself has aesthetic characteristics, which makes it possible to use the concepts and categories of aesthetics in the study of historical events. The source of the aesthetic fullness of a historical event is the creative nature of human activity in general, the revolutionary impulse, heroic enthusiasm and creative potential of mass popular movements. The phenomenon of social revolution is presented as an event in which the aesthetic component of historical action is concentrated. The global revolutionary social shifts of our time are largely achieved through the selfless steps and inspired social creativity of popular movements, whose participants, whether they realize it or not, are engaged in practical, often heroic, transformation of an imperfect world and the creation of a new, more perfect one, the harmony of which is revealed as constructive solvability contradictions.
Image of the Future: An Optimistic Tragedy
Authors: Tereshchenko N. A. 
Published: April 2024

The article raises the question of possible variations of attitude to the future, both in theoretical discourses and in the worldview of the contemporary. The problem of the future (humanity) is put in the context of the problem of crisis of the modern state of society, including the context of the crisis of modern capitalism. The author shows that modern capitalism, which has spread to the whole world, no longer has opportunities for extensive development and for taking its crisis phenomena outside its own system. In this regard, there is a way to solve the internal problems of this system on the principle of bringing them into the future. The article demonstrates two versions of understanding the future: the first one – a return to the past – represents either a retreat backwards in order to free up space/time for a subsequent intensive move forward, or a version of barbarization/archaization/primitivization of the present, conscious or not. The second version of the future’ image, with all its possible tragicism, is the image of the future as a future, another, different, something that has not yet happened. This version requires a new social theory that explains the process and allows to develop an action strategy.
The "Great Game" of World Powers and the social base of antagonisms
Authors: Belyaev V. A. , Sibaeva G. R. 
Published: April 2024

The article substantiates the separation of the concepts of the unity of purpose of the strategy (including the strategy of responsibility of the "circular review") and the variability of the main and main enemy. The authors believe that the main opponent of the West at the moment is Russia, and the main opponent for a long strategic period is China. The inconsistency of the West's simultaneous opposition to these antagonists is argued. The authors analyze the reasons for the variability of the "Big Game" of the world powers. The "globalist" layers are identified and systematized. The groups of antagonists within Russia itself are also highlighted. The variants of conflicts that can provoke these groups and the possibilities of their union and political advancement are considered. The main types of Westernism are also revealed.
Differentiation of the indices of collaboration and resistance of tritagonists and deuteragonists as limitrophes
Authors: Belyaev V. A. , Sibaeva G. R. 
Published: April 2024

The article reveals the possibilities of labile intermediate actors coming to the fore. An unstable vector of limitrophs in the intercivilization zone is determined. The authors separate deuteragonists as those who have accepted the values of the protagonist and therefore are his strong ally, and tritagonists as limitrophes who have mixed values and therefore are able to move away from the protagonist to his antagonist at any moment. It is proved that the level and stability of the loyalty of limitrophs correlate with the indices of collaboration and resistance. The authors identify the causes and negative aspects of collaboration for the life of individual countries, the role of historical, social and mental prerequisites that prevent the realization of basic national interests, as well as the causes and motives of resistance.
Gender imbalance in the labor market: causes and features
Authors: Eflova M. Yu. , Viugina М. A. 
Published: April 2024

The article examines current research on labor mobility and gender inequality in the labor market: occupational segregation, unequal pay and the «maternity penalty». The study of the impact of gender stereotypes, social foundations, choice of educational path and professional environment on wage disparities between women and men was conducted. Wage imbalances are widespread around the world and affect the majority of economic sectors and employment types. In Russia data on the gender pay gap varies widely by region, economic sector and occupational group, and where male employment prevails, the rate of disparity is often higher. The recommendations from international organizations on equalizing women and men in labor rights are given.

The features of phase and structural transformations in composite materials based on systems of immiscible components Al – Be, Al – Be – Mg, Fe – Cu, Fe – Cu – Pb under the influence of concentrated heat sources — electric arc, electron and laser beams — are considered. It is shown that when materials of the Al – Be, Al – Be – Mg systems are exposed to an electric arc plasma and an electron flow, they are melted and subsequently cooled by grain grinding, formation of a zone of thermal influence and crystallization of the resulting new structures and phases. In zone of thermal influence, the enrichment of the aluminum matrix with Be particles is observed due to the thermal diffusion processes of their movement. When plasma is exposed to an arc discharge, pulsed and continuous laser radiation, as well as the flow of electrons on the composition Fe – Cu, Fe – Cu – Pb, a change in the morphology of the near-surface layer is observed: the irradiated material in the melt zone is exfoliated and in the process of crystallization the stratified phases are fixed in a solid state. The mechanism of stratification formation is associated with the limited solubility of the elements that make up the composition in the liquid and solid states.

The article presents the results of a study of the effect of strontium additives (0.01 – 1.0 wt. %) as a structure modifier on the anodic behavior of lead babbit (PbSb15Sn10Sr) in the NaCl electrolyte medium. The studies were carried out by the potentiostatic method in the potentiodynamic mode with a potential sweep rate of 2 mV/s. Studies have shown that over time, the free corrosion potential of alloys shifts to the positive side and with an increase in the concentration of the modifier (strontium) in lead babbit, it acquires a positive value. The addition of strontium to lead babbitt (PbSb15Sn10Sr) increases its corrosion resistance by 10 – 15 %. An increase in the corrosion rate of alloys was noted, regardless of their composition from the NaCl concentration in the solution. Studies have shown that an increase in the concentration of the chloride ion in the NaCl electrolyte leads to a decrease in the potentials of free corrosion, repassivation, and pitting of alloys.
Indifference in Recent Russian Films: The Gulag Face of Cruelty Returns
Authors: Dzero Irina 
Published: April 2024

Abstract
Several recent Russian films show victimizers become victims, and victims— victimizers. This random division into victimizers and victims was forced on society by Stalin, who enjoyed sending his intimate friends-victims (and their wives, children, and relatives) to torture and death. Millions of innocent Russians were captured, killed, or sent to the Gulag, but in an unprecedented way, they were also made to implicate their own intimate friends and family members and become victimizers in their turn. Alternatively, the NKVD torturers were also turned into victims, periodically killed off and replaced by new recruits. Testimonies of Shalamov, Ginsburg, and Dovlatov show that when intimate relationships shrink to command-compliance, both victimizers and victims shed emotions, including shame and guilt, and aggression becomes the only socially meaningful action and the last available entertainment. I identify the visual metaphor of this dynamic, the always identical indifferent face of cruelty, in the films Burnt by the Sun, The Return, Elena, Loveless, and Captain Volkonogov Escaped.
Samrat Upadhyay’s “During the Festival”: A Psychoanalytic-Feminist Exploration of Desire
Authors: Poudel Shyam Prasad 
Published: April 2024

This research delves into Samrat Upadhyay’s short story “During the Festival,” collected in Arresting God in Kathmandu, examines the innate impulses shared by humans and animals within the modern Nepali society. Through a psychoanalytic-feminist theoretical framework, the study critically uncovers the subconscious projections of characters like Ganesh, revealing the complex dynamics of jealousy, sexuality, and familial relationships. Ganesh’s jealousy towards his wife’s emotional relationship with a young man in the neighbourhood reflects deeper insecurities about sexuality and societal norms and values in Nepal, while the neighbour’s displacement of his wife with his mother exposes the unresolved and conflicting issues stemming from the childhood experiences. Drawing on psychoanalytic principles, the analysis explores the themes of infantile fears and psychical metamorphosis, shedding light on the intricate interplay between individual psyche and societal constructs. By dissecting the text’s intrinsic characters and unconscious desires, this research contributes to a deeper understanding of human nature and societal complexities in Nepali literature.

Published: April 2024

The accelerated urbanization in the last decade and population growth in developing countries in the Middle East and North Africa (MENA) region have increased the count of humans exposed to air pollution. This work aims to provide an insight into air quality in the Greater Cairo (GC) area which is one of the largest megacities in the MENA region and is classified as its most polluted city according to the reports of the World Health Organization (WHO). Exploratory data analysis and cluster analysis were used to assess the pollutants data and meteorological data to understand the impacts of weather factors on air quality in GC. According to the results, GC suffers from particle matter of 10 micrometres or less (PM10) pollutants. The annual averages ranged from 97 ± 10 to 203 ± 42 μg/m3. Though short-term exposure to gaseous pollutants did not exceed the limits, the long-term exposures exceeded those in some congested traffic areas. The annual averages ranged from 20 ± 5 to 63 ± 24 μg/m3 for Nitrogen dioxide (NO2) and from 9 ± 3 to 21 ± 5 μg/m3 for sulphur dioxide (SO2). Also, the terrain affects the spatial variation of pollutants observation. There is a negative correlation between the monitoring site elevation and the pollutant concentration.

Published: April 2024

Urea is widely used as nitrogen (N) source for rice fertilization in Costa Rica, despite its low efficiency linked to ammonia losses. To assess urea management alternatives, two field experiments were conducted in the Central Pacific region of Costa Rica to study the effect of N-(n-butyl) thiophosphoric triamide (NBPT) on rice yield and N use efficiency (NUE). In Experiment 1 (Exp1) three tillage treatments (commercial-CT-, reduced-RT-, and reduced tillage with previous subsoiler-RTS-) were evaluated with three N managements: control (without N), urea at 124 kg N ha-1 with and without NBPT. In Experiment 2 (Exp2), a 100 kg N ha-1 rate (with and without NPBT) was evaluated along with a control (without N). NUE was estimated using 15N urea isotopic labeling technique for both trials. In Exp1, a significant difference of 4.8% in NUE for grain was observed among urea with and without NBPT, but no tillage effect was observed. No statistically significant differences were observed in yield among the fertilization treatments (Exp1: 3.56 ± 0.98 t ha-1 for urea and 3.85 ± 0.85 t ha-1 for urea with NBPT; Exp2: 3.38 ± 0.39 t ha-1 for urea and 3.40 ± 0.58 t ha-1 for urea with NBPT) or due to different tillage practices (CT: 3.33 ± 0.79 t ha-1, RT: 3.56 ± 0.74 t ha-1, and RTS: 4.23 ± 0.98 t ha-1). Although the NBPT is a viable option to reduce ammonia losses, its adoption in tropical conditions might be restricted by the small impact on yield.

Objective: The article aims to provide genetic counseling to a family with two children who were experiencing growth and developmental delays.Methods: Clinical information of the proband was collected. Peripheral blood was collected from core family members to identify the initial reason for growth and developmental delays by whole exome sequencing (WES) and Sanger sequencing. To ascertain the consequences of the newly discovered variants, details of the variants detected were analyzed by bioinformatic tools. Furthermore, we performed in vitro experimentation targeting SNX14 gene expression to confirm whether the variants could alter the expression of SNX14.Results: The proband had prenatal ultrasound findings that included flattened frontal bones, increased interocular distance, widened bilateral cerebral sulci, and shortened long bones, which resulted in subsequent postnatal developmental delays. The older sister also displayed growth developmental delays and poor muscle tone. WES identified compound heterozygous variants of c.712A&gt;T (p.Arg238Ter) and .2744A&gt;T (p.Gln915Leu) in the SNX14 gene in these two children. Both are novel missense variant that originates from the father and mother, respectively. Sanger sequencing confirmed this result. Following the guideline of the American College of Medical Genetics and Genomics (ACMG), the SNX14 c.712A&gt;T (p.Arg238Ter) variant was predicted to be pathogenic (P), while the SNX14 c.2744A&gt;T (p.Gln915Leu) variant was predicted to be a variant of uncertain significance (VUS). The structural analysis revealed that the c.2744A&gt;T (p.Gln915Leu) variant may impact the stability of the SNX14 protein. In vitro experiments demonstrated that both variants reduced SNX14 expression.Conclusion: The SNX14 gene c.712A&gt;T (p.Arg238Ter) and c.2744A&gt;T (p.Gln915Leu) were identified as the genetic causes of growth and developmental delay in two affected children. This conclusion was based on the clinical presentations of the children, structural analysis of the mutant protein, and in vitro experimental validation. This discovery expands the range of SNX14 gene variants and provides a foundation for genetic counseling and guidance for future pregnancies in the affected children’s families.
