РОЗРАХУНОК ГАЗОРОЗПОДІЛЬНИХ МЕРЕЖ З УРАХУВАННЯМ ПРОФІЛЮ ТРАСИ
Authors: Середюк М. Д. , Мотрук Н. В.
Published: February 2025

На сьогодні питання будівництва нових та реконструкції існуючих газорозподільних мереж України безпосередньо пов’язані з удосконаленням методів їх проєктування та експлуатації. Частина газорозподі-льних мереж України прокладена або планується до проєктування та будівництва на територіях зі складними топографічними умовами. Це стосується, насамперед, систем газопостачання населених пунктів західних областей України. До сьогодні газодинамічні розрахунки зовнішніх газових мереж проводять без урахування впливу профілю траси через відсутність розуміння важливості цього чинника та неврахування його в нормативних методиках. Метою роботи є встановлення впливу профілю траси на газодинамічну енерговитратність газорозподільних мереж високого, середнього та низького тисків. Базуючись на рівнянні Бернуллі для усталеного режиму руху реального газу у трубопроводі, за результатами теоретичних дослі-джень одержано розрахункові формули для встановлення зміни тиску в газорозподільних  мережах високого, середнього на низького тисків з урахуванням впливу профілю траси, особливостей їх геометричної структури та режимних параметрів. Для газових мереж низького тиску передбачено додаткове урахування гідростатичного напору. Встановлено, що для газових мереж всіх категорій тиску при фіксованій витраті газу величина уточнення газодинамічних втрат тиску врахуванням профілю траси лінійно залежить від геометричного нахилу ділянки. Коефіцієнт пропорційності в лінійній залежності з достовірністю апроксимації понад 99 % описується степеневою функцією від числа Рейнольдса. Одержано, що для газопроводу діаметром 108х3 мм із відносно невеликим геометричним нахилом 0,1 та середнім завантаженням уточнення газодинамічної енерговитратності становить: за високого тиску - 60 %; за середнього тиску - 48 %; за низького тиску при додатковому врахуванні гідростатичного напору - 101 %. Результати досліджень довели необхідність врахування профілю траси при проєктних та експлуатаційних розрахунках газорозподільних мереж всіх категорій тиску.

У зв’язку із науково-технічним прогресом буріння похило-скерованих свердловини набуло значного поширення. Визначальним фактором, який забезпечує безаварійне та ефективне спорудження таких свердловин, є вибір орієнтованої компоновки низу бурильної колони, яка повинна забезпечувати необхідну точність управління траєкторією свердловини та високі техніко-економічні показники їх буріння. Вибір конструкції низу бурильної колони залежить від наявного технологічного обладнання, а також техніко-технологічних та гірничо-геологічних умов буріння та повинен бути достатньо обґрунтованим. Одним із поширених методів обґрунтування вибору компоновки низу бурильної колони є моделювання процесу буріння свердловини. Дана робота присвячена розробленню математичної моделі взаємодії орієнтованої двоопорної компоновки низу бурильної колони, що споряджена генератором осьових коливань, зі стінками скерованої свердловини. Для цього проведено аналіз компоновок низу бурильної колони, що використовуються при бурінні скерованих ділянок свердловин, а на їх основі розроблена механічна та математична моделі досліджуваного об’єкту. При моделюванні приймалось, що між стінками свердловини та бурильною колоною виникає тертя, опису-ване моделлю Кулона, а впливом протікання промивальної рідини нехтувалось. Математична модель отримана на основі рівняння Лагранжа ІІ роду із застосуванням підходу із наданням колоні фіктивних степенів вільності, що дає змогу визначити реакції в’язей із застосуванням принципу можливих переміщень. В результаті отримано систему диференціальних рівнянь, з якої визначено сили контактної взаємодії опор компоновки низу бурильної колони із стінками свердловини. Запропонована модель дає змогу визначити зусилля, з якими бурильна колона діє на стінки свердловини, в залежності від кінематичних характеристик руху бурильної колони, геометричних параметрів компоновки, осьового навантаження на долото та параметрів тертя.

Food security is an effort to fulfill basic food needs. Therefore, local food production, specifically sorghum, needs to be increased to enhance national food diversification. Sorghum is one of the agricultural commodities with potential for cultivation as an alternative food source besides rice and corn. The purpose of this study is to determine the level of local food security for sorghum and the welfare level of sorghum farmers in Jerowaru District, East Lombok Regency. The research was conducted in Pemongkong Village, Jerowaru District, East Lombok Regency. The tool used in the research was a questionnaire with a sample size of 30 respondents. The research area was determined deliberately (Purposive Method) with sampling techniques using random sampling. To measure the welfare level of sorghum farmers, a 5-point Likert scale was used, which was then scored using the composite method. The IKP (Food Security Index) per hectare was 1.28, indicating that sorghum production per hectare is more than sufficient to meet the family's food needs. An IKP greater than 1 suggests that the family's food security can be met or even exceed their basic needs. However, while the IKP indicates food sufficiency for the family, the Food Security Ratio (RKP), calculated from the ratio between KP and the total food needs across all food types (rice, maize, sorghum), shows a lower value. For per hectare, the RKP is only 0.25, which means that sorghum production can only fulfill about 25% of the total food needs that include rice, maize, and sorghum. Overall, the average composite score for all indicators of sorghum farmers' welfare level is 0.61, which falls into the High category. This indicates that in general, the performance of the various indicators is quite good, although some aspects, such as business security and farmer skills, require more attention for improvement.

Presupuesto participativo rural: virtual vs presencial
Authors: Caceres Cabana Yezelia
Published: February 2025

Introducción: El artículo analiza dos procesos de presupuesto participativo, uno virtual y otro presencial, en dos zonas rurales peruanas similares, reflexionando sobre las características prevalentes tras 20 años de la ley de elaboración obligatoria del presupuesto participativo en condiciones de crisis, y el impacto de la virtualidad versus la presencialidad en la realización de talleres. Metodología: Se realizaron 25 entrevistas en profundidad con participantes y autoridades, procesadas con el software Nvivo. Resultados: Indican que, independientemente del formato, la participación se ve limitada por la falta de credibilidad, confianza y legitimidad, ya que los acuerdos no son legalmente obligatorios. Discusión: Sugiere que la presencialidad es preferible incluso en contextos de lejanía territorial, debido a las limitaciones de acceso y uso de internet. Conclusiones: Destacan que la falta de credibilidad en el cumplimiento de los acuerdos y la legitimidad de las autoridades afecta los procesos tanto presenciales como virtuales. Además, la implementación de un modelo generalizado, sin considerar las disparidades territoriales y la virtualidad, ha dificultado la adaptación en zonas rurales, concentrando decisiones y limitando la participación efectiva.

THEORETICAL ANALYSIS OF THE ISSUE OF DEVELOPING MUSICAL ABILITIES OF INDIVIDUALS
Authors: Panasiuk Anton
Published: February 2025

The article discusses various aspects and provides a theoretical analysis of research on the development of musical abilities and their impact on personality psychology. Several studies point to potential mechanisms underlying the development of musical skills and the influence of music on brain activity. The interest of scientists in the problem of developing musical abilities in personality is highlighted within the context of neuroscience, the influence of the emotional sphere on music perception, and the formation of musical preferences in both children and adults. The article examines the issue of musical ability development and its age-specific characteristics, their structure, and the role of general abilities in musical development. The article aims to examine and systematize the theoretical aspects related to the development of musical abilities in individuals, to study contemporary theories, to consolidate scientific approaches, and to deepen research in this field. The research provides definitions of the concept of "musical abilities" by representatives of various fields of knowledge: psychology, musicology, music pedagogy, as well as their classification. A characterization of musicality as a special mental function and the concept of the synesthetic nature of musicality are provided. It has been proven that musicality influences personality development, making it more integrated and balanced, fostering the development of various aspects: intellectual, emotional, social, and creative. It is noted that a person's musical giftedness is based on sensory musical abilities, the main ones being musical ear, sense of rhythm, and musical memory. The article examines the issue of developing musical ear - the most important sensory musical ability, the development of which is associated with a high level of human mental evolution. A number of scientific studies on the perception of musical rhythm are analyzed, and the development of a sense of musical rhythm in children is discussed. The definition of the concept of musical memory as a separate musical ability is provided, describing its classification, functioning, and interrelated types. Emphasis is placed on the necessity of continual training for its development and improvement. The concept of musical thinking and musical imagination is separately examined, reflecting aspects of cognitive and creative activity in music. Conclusions are drawn regarding the development of musical abilities as a universal tool for personal growth.
GENDER ASPECTS OF SOCIAL AND PSYCHOLOGICAL ADAPTATION STRATEGIES AMONG INTERNALLY DISPLACED PERSONS (IDPS)
Authors: Maksymeniuk Volodymyr , Popova Olena
Published: February 2025

Due to the military aggression by a neighboring hostile state, many Ukrainians have been forced to leave their permanent residences and relocate to safer regions of Ukraine and abroad, receiving the status of internally displaced persons (IDPs). The social and psychological adaptation of IDPs in their new environments is one of Ukraine’s pressing social issues. Forced relocation to a new and unfamiliar social environment significantly impacts their physical and psychological well-being, affecting their adaptive capacities, socialization, and quality of life.
The article argues that one of the most important aspects of socio-psychological adaptation is gender behavior. Gender characteristics of adaptation differ depending on the dominance of the expression of masculine or feminine character traits. Psychological masculinity is largely associated with the individualization of the personality, the gradual development of its independence from the environment to autonomy, from conformism to free self-determination. Psychological femininity is associated with the decentration of the personality, that is, the shift of the motivational and value dominant from egocentric and group-centric aspirations to universally compassionate and altruistic ones. Moreover, such decentration is based on unconscious processes, is manifested directly in feelings and desires and is not subject to direct volitional regulation.
Gender-based attitudes and stereotypes play a crucial role in forming social actions and behavioral strategies that affect individuals' adaptive abilities. This article presents a study of gender aspects in the social and psychological adaptation of IDPs from the Kherson region who have relocated to Vinnytsia. The findings indicate that gender differences in adaptation significantly influence psychological and social adaptation to new living conditions. The study identifies two key adaptation strategies among IDPs: “acceptance of responsibility” and “positive reappraisal,” with selection influenced by gender-based stereotypes among male and female IDPs.
Illness and Enlightenment
Authors: Deane Susannah
Published: February 2025

Tibetan understandings of nyoné — ‘madness’— encompass a broad range of concepts. Perspectives on the causation and treatment of madness as an illness are informed by Tantric and medical understandings of mind-body structure and (dys)functioning, as well as people’s relationships with non-human entities. In addition, ‘madness’ may be seen as a sign of enlightenment in the case of some Tantric practitioners. Based on ethnographic fieldwork in the Tibetan region of Amdo in northwest China, as well as examination of Tibetan medical and religious texts, Illness and Enlightenment explores the multi-faceted concept of nyoné through key Tibetan concepts of wind, heart, and mind, as well as human-spirit relationships.
Market and Monastery
Authors: Ratanapruck Prista
Published: February 2025

In the established historiography of trade in Asia, the emergence of Western trading empires invariably triggered the decline and dispersal of old trading networks. In this transregional ethnographic history of the Manangi, a Buddhist trading community from northern Nepal, Prista Ratanapruck provides counter evidence, elucidating how kinship, social, and religious institutions have facilitated the expansion of Manangi trade across South and Southeast Asia. Expounding on how social and moral values shape capital production, accumulation, and redistribution, Market and Monastery examines the entwining relationship between trade and the Manangi’s pursuit of social and spiritual aspirations, ultimately illuminating an intriguing form of capitalism.
Towards a British Natyam
Authors: Gorringe Magdalen
Published: February 2025

The story of the emerging professionalization of classical Indian dance forms in Britain is wrought with contradictions. Though becoming increasingly popular within mainstream culture, the forms lack the clear routes to vocational training so essential for creating a dance career in the traditional sense. Towards a British Natyam uses this lens to analyze the cultural, social, and political frameworks that make a profession possible within the arts. Innovatively drawing on the work of decolonial theorists and the sociologist Pierre Bourdieu, Gorringe illuminates the transformative potential of a classical Indian dance profession to decenter white supremacist modes of knowledge formation and recenter pluriversality.
Representations of “Japanese Nature”
Authors: Ohnuki-Tierney Emiko
Published: February 2025

“Nature” as a concept and word is extremely elusive, yet it is commonly taken for granted that “the pristine nature” is “out there.” This book explores the factors that have naturalized the idea of nature as “pristine” into our psyche, and as something that has a spatial, visual, and temporal dimension for “seasons”. Much emphasis is given to the inhabitants demonstrating the dynamic characteristic of nature. As a study done over a long period of history, Representations of “Japanese Nature” shows the mutual support between conceptual principles of nature and the daily activities of the people.
The Island of the Pope
Authors: Kousouris Dimitris
Published: February 2025

For the Aegean island of Syros, the Greek Revolution (1821-1832) marked a significant turning point. Known as “the island of the Pope”, due to its Catholic majority, Syros transformed into a major commercial hub, seemingly triggering the withdrawal of its indigenous Latin community. Juxtaposing the view from the Archipelago with that from Istanbul, the Peloponnese, Rome, Paris and Vienna, this volume revisits the island’s history. From early encounters between native inhabitants and groups from across the Ottoman Levant, to how the Latin community navigated conflict and change during the Greek War of Independence, this book offers new insights into the political, cultural and social history of the region.

The article is dedicated to the issues of forming the investment-innovation strategy for food industry enterprises in the context of digitalization and a risky environment. The aim of the article is to substantiate the investment-innovation strategy for food industry enterprises, considering the current risks and the digital transformation of the country’s economy.The article examines the investment-innovation activity of food industry enterprises and its role in ensuring their competitiveness in the face of modern economic challenges. The study analyzes existing approaches to the formation and implementation of investment-innovation strategies in enterprises and substantiates the importance of integrating investments in the development of innovative technologies to achieve sustainable economic growth. It is revealed that the investment-innovation strategy is a key tool for improving the efficiency of enterprises and adapting to changes in the global economic environment.The research identifies that the investment-innovation activity of food industry enterprises is accompanied by numerous risks that directly affect their financial stability, production efficiency, and market prospects. The main risk groups include financial (high capital intensity, limited access to financing, instability of exchange rates, low investment profitability), technological (significant costs for research and development, rapid technological obsolescence, integration difficulties), market (demand uncertainty, competition, production seasonality, raw material price fluctuations), regulatory (changes in environmental requirements and tax policy), organizational and personnel (insufficient staff qualifications, resistance to change, risk of ineffective management), and environmental (climate changes, growing waste disposal requirements).The study substantiates the investment-innovation strategy for food industry enterprises, aimed at improving production efficiency, creating value-added products, reducing costs, improving product quality, and minimizing environmental impact. It is determined that to achieve the goal, the enterprise should follow a set of principles: sustainable development, digital transformation, flexibility, adaptability, cooperation, partnership, and risk management. The proposed strategy includes a comprehensive set of measures in the following directions: technological modernization, innovative product development, environmental sustainability, financial support, staff development, and digital marketing. The implementation of the investment-innovation strategy for food industry enterprises will ensure a range of positive changes aimed at increasing the effectiveness of their operations and strengthening market positions: increasing the profitability of food enterprises, entering new markets, optimizing production processes, enhancing customer loyalty, and improving the level of innovation culture and digital literacy of staff.

Beaufsichtigen. Über die Herausforderung, Unschädlichkeit zu organisieren (online first)
Authors: Kette Sven , Kühl Stefan
Published: February 2025

Der Beitrag untersucht die spezifischen Herausforderungen, die mit der Einführung agiler Prinzipien in Aufsichtsbehörden verbunden sind. Während eine prinzipienbasierte Regulierung zunehmend flexible und zukunftsorientierte Entscheidungsfindungen fordert, bleibt der Druck zur genauen Einhaltung rechtlicher Rahmenbedingungen bestehen. Gezeigt wird, wie hieraus eine Spannung zwischen Genauigkeit und Geschwindigkeit des Entscheidens resultiert. Diese Spannungen reichen Aufsichtsorganisationen an ihr Personal weiter, wodurch sich neue Zumutungen ergeben, verstärkt Verantwortung zu übernehmen und Unsicherheiten zu handhaben. Abschließend skizziert der Beitrag Ansatzpunkte, die Zumutungen an das Personal organisationsstrukturell abzufedern und damit die Spannung von Genauigkeit und Geschwindigkeit handhabbar zu gestalten.

BACKGROUND:

Lorry drivers work tirelessly behind the wheels, commuting from one place to another without regular and adequate food, rest and sleep. These people often have odd working hours, long work shifts with frequent changes to their work schedule. In addition, they work in unfavorable climate conditions and face variety of problems like traffic congestions, vehicle fumes, vibrations and poor conditions of roads. Due to this hectic schedule they commonly fall prey to unhealthy lifestyle habits in the form of alcohol consumption, smoking, tobacco chewing etc. mainly to relieve stress. Considering all these factors, lorry drivers form a potential high risk group for oral problems.

OBJECTIVE:

The present study aimed to assess the oral health status among lorry drivers in Hyderabad city.

METHODS:

A total of 611 subjects constituted the study population. Data collection included demographic details and assessment of dentition status, periodontal status and presence of oro-mucosal lesions using modified World Health Organization (WHO) Oral Health Assessment form, 2013. The data was analyzed using Statistical Package for Social Sciences (SPSS) package version 21.0. Descriptive statistics were carried out for the demographic variables. Chi square test, Mann Whitney U test, Analysis of Variance and regression analysis determined the association and compared the mean scores based on variables. p < 0.05 was considered statistically significant.

RESULTS:

The mean dental caries experience was significantly higher among subjects above 40 years (3.11±2.49; p < 0.01*), and those with high school education (3.91±2.75; p < 0.005*). Likewise, a significant difference in the mean number of teeth with bleeding and pockets was observed based on age ( p < 0.01*) and education ( p < 0.01*). Subjects above 40 years and those with primary school education had significantly higher mean scores for loss of attachment ( p < 0.001*). Oral submucous fibrosis on the buccal mucosa was the most commonly seen oral lesion. Regression analysis revealed subjects above 40 years, with high school education and a history of tobacco and alcohol consumption to have higher odds for DMFT, poor periodontal health and oral mucosal lesions.

CONCLUSIONS:

The study revealed that lorry drivers had a high prevalence of dental caries, poor periodontal status and oro-mucosal lesions. Therefore, it creates an alarming need to focus on these high risk groups with special emphasis on primary oral health care programs to prevent accumulation of health care demands among them.

The way of definition of optimum angles of the inclination of flat solar collector of the southern orientation to the horizon plane on condition of monthly (12 months) changes of slope angle is developed, considering sunshine probability around construction.
For every month of year curve dependences of the energy falling on 1 sq.m of the plane of the collector of the southern orientation for Sarny town on slope angle of the collector to the horizon plane in degrees are shown, considering probability solar shine. All curves are also shown together in one drawing that allows to compare conveniently them.
The statistical duration of sunshine in hours undertook according to the observations of the actinometric station in Sarny town presented in the form of the polynom of the fourth degree depending on number of day of year, and the maximum (astronomical) duration of sunshine was calculated in the program developed by authors as solar time from rising to the decline in this day of year.
The relation of statistical duration of sunshine to maximum (astronomical) was treated as sunshine probability in this day of year. Of course, such treatment is rather approximate as actually it is advisable to accept the relation of statistical duration of sunshine over the collector's plane to the maximum (astronomical) duration of sunshine over the collector's plane too. But there are no necessary data on such statistical duration yet.
All curve dependences of the energy getting on 1 sq.m of the plane of the collector of the southern orientation have one well expressed maximum that allowed to define it for every month, previously interpolating values parabolic splines, and, thus, to define the optimum angle of the inclination of the collector for this month.
The way can be used (in the presence of statistical data for the area of construction on sunshine duration) and for other periods of year, for example spring-summer-fall, considering that snow on the planes of collectors can long lie in certain areas of construction. Other periods of year can be used also for the reasons which do not have relations to climatic conditions, and connected, for example, with the schedule of electric power consumption.
NUMERICAL STUDY OF THE STABILITY OF A SHELL OF MINIMAL SURFACE ON A SQUARE CONTOUR UNDER THERMAL AND POWER LOADING WITH CONSIDERATION OF GEOMETRIC NONLINEARITY
Authors: Kosheviy Aleksandr
Published: February 2025

Design is a crucial stage in the creation of building structures, during which the technical characteristics of the product are determined and the feasibility of the task is checked. The design solutions laid down at this stage determine the efficiency of the structure as a whole, its strength and performance characteristics.
The necessary set of requirements is the main design problem, which in turn is solved by structural and applied mechanics. The process of creating the best design is called optimization, or optimal design. The method of optimal design is of great importance, which affects the result of the efficiency of the building structure as a whole.
Of great importance is the calculation of strength, which allows us to assess the viability of power schemes, comparing the estimated weight characteristics of the layout of different materials, and find the main dimensions at which the weight of the structure will be minimal.
The design of a structure for stability is based on destructive loads and is reduced to determining the critical load of loss of stability, which should be no less than the operational load. Safety factors, as well as for structures that work for strength, are assumed to have different values depending on the class of construction consequences CC1, CC2, CC3.
When designing, the issue of weight optimization usually arises. In this case, it is necessary to quickly determine the weight of structures for given dimensions and external loads, and find its main geometric parameters. In order to find the right design solution that ensures the minimum weight of the structure, it is necessary to understand how certain parameters affect stability and to what extent.
The study of stability taking into account geometric nonlinearity, namely iterative loading, makes it possible to use the material efficiently. The maximum stresses are 240 MPa and the maximum displacements are 73 mm. The eigenvalues of the safety factor are equal to 1.005756, which means that there is no safety margin in the shell, and we can further use these results for multi-criteria parametric optimization, and the results of the study are confirmed by the authors' methodology for objects where optimization of the shell geometry is taken into account.
