Published: February 2025

The article highlights the relevance of psychological support for volunteers working in difficult conditions associated with social, humanitarian and crisis challenges. The main psychological problems faced by volunteers are considered, including emotional burnout, high stress levels, secondary traumatization and overload, which lead to a decrease in their productivity and the threat of emotional exhaustion. Special attention is paid to the impact of these factors on the mental health of volunteers, as well as on their ability to maintain resilience in emergency conditions. Modern methods of psychological support are analyzed, which allow to prevent emotional burnout and contribute to maintaining mental balance. It is noted that group interventions, such as therapeutic or support groups, contribute to creating a sense of belonging and mutual support among volunteers; coaching approaches help to identify personal resources and set achievable goals, and art therapy allows to express emotions through creativity. Special attention is paid to self-help techniques, such as relaxation exercises, mindfulness and emotional regulation methods, which can be used directly by volunteers in their daily activities.

In this study, we enforced a sustainable and efficient approach to synthesizing zinc oxide nanoparticles (ZnO-NPs) by employing the Dalbergia sissoo leaf extract. Biosynthesized ZnO-NPs have been characterized by various techniques (XRD, TEM, FT-IR, UV-VIS, FESEM and EDX). The ZnO-NPs exhibited a prominent absorption peak at 288 nm in the UV-Vis spectrum, indicating their optical characteristics. X-ray diffraction (XRD) pattern confirmed that these nanoparticles were crystalline, specifically displaying a hexagonal wurtzite phase. The FESM images showed a range of surface morphologies for the ZnO-NPs, from irregular shapes to nearly spherical forms. XRD and TEM analysis obtained that the ZnO-NPs have average crystallite sizes of 15.86 nm and 18.68 nm, respectively. ZnO-NPs demonstrated antimicrobial effectiveness against gram-positive (S. aureus, B. subtilis) and gram-negative (E. coli, P. aeruginosa) bacteria strains. B. subtilis exhibited the most significant inhibition zone, measuring 22.5 ± 0.18 mm at a 100 μg/mL concentration. In vivo studies conducted with mice have demonstrated that synthesized ZnO-NPs exhibit significant potential for promoting wound healing. These investigations reveal that applying ZnO-NPs leads to enhanced tissue regeneration and accelerated healing processes, suggesting their promising role in wound treatments.

В статье поставлена задача выявить особенности церковно-агиографических сочинений П. А. Смирнова и дать обзор первых рецензий на его труды. Для реализации поставленной задачи был проведён источниковедческий анализ сочинений с применением методов сравнительного анализа, систематизации и критической интерпретации источников. Первое жизнеописание «Жизнь и учение преосвященного Феофана Вышенского Затворника» было подготовлено к десятилетию со дня кончины святителя при поддержке настоятеля Вышенской пустыни и сотаинника святителя архимандрита Аркадия (Честонова, 1821–1907). Книга, написанная современником святителя, жившем рядом с обителью и имевшим возможность часто посещать её, получилась живой и фактологичной и получила одобрение со стороны рецензентов. Особенностью церковно-агиографических трудов П. А. Смирнова является включение в канву повествования не только сведений о жизни, но и больших подробных тематических разделов из духовного наследия свт. Феофана Затворника. Таким образом, проделанная составителем работа позволяет читателям в значительной мере познакомиться не только с жизнью, но и с творениями святителя. До сих пор труды П. А. Смирнова являются основополагающими для всех, кто начинает изучение жизни и трудов свт. Феофана.

The article aims to identify the features of the church hagiographic writings of P. A. Smirnov and give an overview of the first reviews of his works. To achieve this task, a source analysis of the works was carried out using methods of comparative analysis, sys­­tematization and critical interpretation of sources. The first book, The Life and Teachings of His Grace Theophan the Recluse of Vyshensk, was prepared for the tenth anniversary of the death of the saint with the support of the abbot of the Vyshenskaya Desert and co-priest of St. Archimandrite Arkady (Chestonov, 1821–1907). The book, written by a contemporary of the saint who lived near the monastery and had the opportunity to visit it often, turned out to be lively and factual and received approval from reviewers. The peculiarity of P. A. Smirnov’s church hagiographic works is the inclusion in the outline of the narrative not only information about life, but also large detailed thematic sections from the spiritual heritage of Theophan the Recluse. Thus, the work done by the compiler allows readers to get acquainted to a large extent not only with the life, but also with the works of the saint. To this day, the works of P. A. Smirnov are fundamental for everyone who begins to study the life and works of St. Theophan.

Authors: Толмачёв Леонид
Published: February 2025

В статье рассматривается начало жизненного пути известного иерарха и церковного деятеля архиепископа Никона (Рождественского). Целью исследования является выявления духовных наставников, повлиявших на формирование мировоззрения будущего владыки. Основными источниками выступают дневники, письма и воспоминания архиепископа Никона, которые сохранились в его архивном фонде. Используя метод сравнительного анализа малоизученных архивных данных и опуб­ликованных воспоминаний, предпринимается попытка реконструировать процесс общения будущего владыки с духовниками в период его обучения в Московской духовной семинарии. В результате автор приходит к выводу, что после окончания семинарии именно влияние настоятеля Ново-Иерусалимского монастыря архимандрита Леонида (Кавелина) определило для владыки Никона выбор монашеского пути.

The article examines the beginning of the life of the famous hierarch and church figure Archbishop Nikon (Rozhdestvensky). The purpose of the study is to identify spiritual mentors who influenced the formation of the worldview of the future bishop. The main sources are the diaries, letters and memoirs of Archbishop Nikon, which have been preserved in his archive fund. Using the method of comparative analysis of little-studied archival data and published memoirs, an attempt is made to reconstruct the process of communication between the future bishop and his confessors during his studies at the Moscow Theological Seminary. As a result of the conducted research, the author comes to the conclusion that after graduating from the seminary, it was the influence of the rector of the New Jerusalem Monastery, Archimandrite Leonid (Kavelin), who determined the choice of the monastic path in life for bishop Nikon.

Published: February 2025

The kissing gourami (Helostoma temminckii) is a freshwater species increasingly cultivated in controlled aquaculture systems. However, its production is hindered by the limited availability of broodstock and fry, which still heavily depend on natural catches that fluctuate seasonally. To address this challenge, controlled environment aquaculture offers a sustainable solution to boost the kissing gourami population. One effective method is semi-natural spawning through gonadotropin hormone induction using Ovaprim®, which promotes year-round reproductive readiness in broodstock. This study aims to apply and evaluate the semi-natural spawning technique of kissing gourami using Ovaprim® at UPR Doa Mandeh, Ogan Ilir. Conducted between August and September 2024, the research compared two treatments: natural spawning (P0) and semi-natural spawning (P1). The findings demonstrated promising results, with a fecundity of 9,619 eggs, a fertilization rate of 90.4%, a hatching rate of 94%, and a survival rate of 95%. Water quality parameters remained within optimal ranges, with broodstock pond temperatures between 30–30.6°C and pH levels of 7.27–7.53, while the rearing aquarium maintained a temperature of 31°C and a pH of 7.62–7.66. These results highlight the potential of semi-natural spawning using Ovaprim® as a viable approach for enhancing kissing gourami reproduction, reducing dependency on wild populations, and supporting sustainable aquaculture practices.

Terrorism is now a global threat that involves various aspects of life, transcends national borders, and has become a serious international crime. Indonesia, as a developing country, faces significant threats, especially through bomb terror acts in various regions. The terrorism movement is considered a major threat to humanity that needs to be addressed immediately. This study uses a qualitative method with informants including the village government, community leaders, security forces, and residents of Penatoi Village. Data collection techniques include observation, interviews, and documentation studies. The results of the study show that the strategic role of the village government in preventing terrorism is realized through the pentahelix approach, involving various elements such as Babinsa, Bhabinkamtibmas, religious leaders, and youth leaders. Efforts such as socialization, education on the dangers of terrorism, and provision of basic necessities have succeeded in changing the pattern of community interaction from exclusive to more open, even 80% of residents exposed to radicalism have re-pledged their loyalty to the Republic of Indonesia. Inhibiting factors for the pentahelix approach include budget constraints, dissatisfaction with government assistance, and the existence of underground movements. However, the support of former terrorist convicts as partners and cooperation between the government and various parties, including BNPT and the police, are significant supporting factors in preventing terrorism.

tional process for applicants of engineering and technical specialties in the distance form of education. The main problems that arise in the system of the teacher-apprentice during training are highlighted. The most common situations that cause students the greatest concern and contribute to a decrease in the effectiveness of learning material during the educational process in a distance format, covered by the martial law regime in our country, have been considered and analyzed. This situation, in which all the participants of the educational process found themselves, certainly has an impact on the mental and emotional state and the quality and readiness of learning the relevant competencies according to the direction of the educational program corresponding to the specialty of the applicant.
In turn, scientific and pedagogical workers, who found themselves in the same difficult life and professional conditions due to the military aggression of the Russian Federation, were able to discover and successfully apply their best organizational, human and pedagogical abilities for the sake of maintaining the quality and further development of the educational process in Ukraine.
Thus, on the basis of the MOODLE distance learning platform, Kharkiv National Automobile and Road University developed and implemented a distance course in the discipline "Draft geometry, engineering and computer graphics" for students of the following majors: 121 "Software engineering", 122 "Computer sciences and information technologies", 131 "Applied mechanics", 132 "Materials science", 133 "Industrial mechanical engineering", 151 "Automation and computer-integrated technologies", 152 "Metrology and information- measuring technology", 274 "Motor vehicle transport". When developing distance courses-resources, teachers focused their efforts on adapting and modernizing the collective, individual and independent work of applicants in order to ensure the greatest efficiency in the assimilation of relevant program learning outcomes.
GEOMETRIC APPROACH TO STABILITY ANALYSIS OF DYNAMIC SYSTEMS WITH TIME DELAY

Published: February 2025

In the paper we consider the linear systems of differential equations with a time delay, which are mathematical models of dynamic systems arising in various fields of mechanics. Delays can occur in systems with variable stiffness or deformation, in systems with complex dynamic interactions, for example, in hydrodynamics or in moving mechanisms. The presence of time delays in dynamic systems is responsible for the rather complex solution behavior and affects the stability of such systems. A geometric approach to studying the stability of linear systems of differential equations with two delay parameters, which is called the -decomposition method of Lee and Hsu, is considered. This method allows studying the influence of time delay deviations on the stability of dynamic systems with a delay. The idea of this method is to construct a stability curve in the space of delay parameters, which divides the parameter space into regions of stability. A non-trivial case is when the characteristic quasipolynomial of a linear system with a delay has a complex root  on the imaginary axis of multiplicity two. The roots of the characteristic quasi-polynomial, as an implicit function of two variable  parameters  and  are not differentiable at a point . In this case, the stability curve has a cuspt at the point corresponding to the complex root on the imaginary axis of multiple of two and divides the parameter space into the G-sector and the S-sector. It is known that there is a mutually unequivocal correspondence between the neighborhood of the point of cusp in the space of parameters and the neighborhood of the complex root of the multiplicity of two of the characteristic quasipolynomial lying on the imaginary axis. This makes it possible to study the behavior of the movement of complex roots on the complex plane when delay parameters are deviated, and therefore to analyze the change in stability of the system with a delay.
A geometric approach to the study of the displacement of complex roots on the complex plane of the characteristic quasi-polynomial of the system with a delay when the parameters of the delay are deviated is applied to a system of two differential equations with two time delays. The characteristic quasipolynomial of the considered system has a complex root  on the imaginary axis of multiplicity two at certain parameter values. The local stability curve of such a system is constructed, the S-sector and G-sector in the parameter space are determined. It is shown that when the values of the delay parameters are moved to the S-sector, the roots around the point  are moved to the left half-plane of the complex plane. Thus, it is established at what deviations of the delay parameters from the point  corresponding to the root, the given system will be stable.
ELASTIC BENDING OF A CURVILINEAR STRIP WITH A GIVEN INITIAL CURVATURE OF ITS ELASTIC AXIS
Authors: Hropost Vyacheslav , Demchuk Iryna
Published: February 2025

The elastic bending of a rod or strip is characterized by the fact that after the deforming load is removed, they fully restore their shape. The deforming load can be a moment, a concentrated force, or a distributed force applied to the strip. If the cantilevered strip is subjected to any of the above loads or their combination, its straight axis will turn into a curved axis. The calculation of the shape of this axis is based on the relationship between the curvature of the elastic axis depending on its length, the applied moment, and the stiffness of the strip, which is known from the resistance of materials. If the stiffness is constant and a concentrated force is applied at the end of the cantilevered strip, the curvature of the axis will be linear, i.e., the curvature of the axis will increase in proportion to its length as it moves away from the point of clamping. Such a curve is known in differential geometry as a clotoid. It has no parametric or implicit equations, so it is constructed using numerical methods.
In general, the curvature of an elastic axis is described by nonlinear differential equations. In the resistance of materials, the linear bending theory is used to calculate the deflections of beams, which provides a simplified solution. For practice, this calculation is acceptable, since beams are characterized by a small deflection of the elastic axis and this approach greatly simplifies calculations. To calculate significant deflections, the linear theory does not provide an accurate result, so it is necessary to look for the curvature of the elastic axis depending on the arc length using a nonlinear theory.
This paper considers the case when the strip is not straight but curved, i.e., it already has an initial curvature of its axis. When forces are applied to a curved strip, this axis deforms, changing its curvature. When the applied forces are released, the strip acquires its original curvilinear shape. An example of such a band deformation is the riser (stand) of a cultivator tine, which can change the curvature of the elastic axis as a result of a variable force applied to the tine. In this article, the elastic axis of such a riser is taken as a curve as a function of the arc length and its possible deflections during operation are calculated.

This work continues previous research on expanding the capabilities of computer modeling and adapting the tools of relevant software packages for the development of design documentation in accordance with standards. The aim of this paper is to develop and use modules that simplify the work of the user of 3D modeling packages. This simplification is achieved using an application programming interface (API) as a special protocol for the interaction of computer software, in particular, in the environment of the Autodesk Inventor package. The main goal is to study object models based on API programs and develop/improve algorithms and methods for creating digital object models. This includes the use of programming languages and features that have appeared in the latest versions of Autodesk Inventor, Fusion 360, AutoCAD, etc. Previously, modules for building the correct conical chamfer for prismatic bodies and for holes that extend onto cylindrical surfaces were proposed.
The paper considers and solves the issues of displaying threaded connections and stiffeners (rib) in cross-sections in accordance with the standards, as well as simplified display of transition lines in places where casting radii are used.
To address the above issues, attention was focused on a deeper study of the API capabilities for managing objects, methods, and properties of their elements belonging to the respective environment. In principle, all operations performed in dialog mode can be programmed using appropriate macros. The application of the proposed algorithms and tools will significantly speed up the process of designing special elements of various parts.

An urgent issue for Ukraine is maintaining the state economy at an appropriate level in the current difficult situation. One of the ways to successfully achieve this goal is to further improve agricultural production. This industry currently plays a leading role in stabilizing the outlined processes.
Important in the above plan is the improvement of the applied technical tools, in particular, tillage tools. A significant number of them are provided with arrow-shaped paws of various purposes. Their working surfaces are somewhat similar, but differ in some way in their shape. The latter significantly affects various parameters and characteristics of land cultivation, in particular, energy indicators.
Modern combined working bodies, along with cultivation, are also used for sowing, for example, using new No-till or Strip-till technologies, require additional theoretical and experimental research. Since, unlike traditional farming, direct sowing is carried out directly into the mulch layer, when stubble and other plant residues create additional resistance to the movement of the working bodies of the seeder. Therefore, it is relevant to study the traction resistance of the combined cultivator-harrow, especially in connection with the geometric parameters of the arrow-shaped paw as the main element of this design.
The main purpose of arrow-shaped paws from the beginning of their appearance was the destruction of weeds by cutting the root system and loosening the soil during continuous main and surface cultivation. Row cultivators with feeding paws which loosen the soil and provide fertilizer at the same time began to be used for inter-row cultivation later. Further improvements in the geometry of the arrow-shaped paws of row cultivators are connected with the formation of agrotechnical methods of inter-row cultivation of crops, in which the soil is moved from the inter-row to the protective zone of the row with the help of shelf-shaped hiller surfaces. It should be noted that since this millennium, both foreign and domestic farmers have widely introduced direct sowing technology into production, where anchor and combined coulters made in the form of arrow-shaped cultivators are also used.
The questions outlined above, using the means of modern computer information technologies, are the subject of research in this publication.
