Introduction. ESG studies are relevant due to both the climate agenda, socio-economic and geopolitical aspects in the growth of modern economy, while the decomposition of national and regional tasks at the municipal level determines the goal setting for the study of ESG models for municipal development. Purpose. The paper aims at identifying and quantifying causal relationships to spot the triple helix in ESG models for municipal development. Materials and Methods. The constituent-functional approach, comparative and correlation analysis were used as the main research tools. The information was taken from the official statistical database of the Federal State Statistics Service, EMISS, as well as the results of the ESG rating of cities done by RA Expert Agency. Results. The study outlined the causal relationships which define the nature of inter-constituent interactions for sustainable development of municipalities. A triple helix was proven to exist in the ESG models of innovative municipal development. This helix reveals the relationships among business entities from the perspective of ESG development. Correlation analysis was applied to prove the differentiation of municipalities, and a typology of ESG models of development is proposed by the key type of interactions in terms of the triple helix. Conclusions. The conducted research actually attributed the analyzed municipalities to one of the selected types, which is confirmed by a comparative analysis with the ratings and expert opinions. The results obtained are of interest for further studies of approaches to the ESG agenda at the municipal level as a part of an interdisciplinary research. The practical value of the proposed tools for identifying the type of ESG development model refers to the opportunities to identify not only weaknesses, but also systemic interactions for higher investment attractiveness and strategizing the ESG development of municipalities.

Published: December 2023

Introduction. Combating tax evasion, the shadow economy and unofficial (illegal) employment are important policy goals in every region. Achieving those goals requires various resources; therefore, it is important to determine the size of the shadow economy to use the resources efficiently. Purpose. The paper aims at developing and testing a methodology for neural simulation estimates to find the size of the shadow economy in an industrial region taken as an example, i.e. the Donetsk People’s Republic. Materials and Methods. The study refers to the data from the World Bank Group’s Ease of Doing Business Index and data about the size of the shadow economy calculated with L. Medina and F. Schneider’s methodology. The neural network learns from the generated data array of 17,160 values for the economies of the world for 2006–2015 with the Statistica software package. The result was then used to estimate the value of the shadow economy in the industrial region. Results. The hypothesis that the Ease of Doing Business Index and the size of the shadow economy are correlated has been proposed and tested. The indicators of the Ease of Doing Business Index and the size of the shadow economy by country were sampled. The neural network was taught to assess the size of the shadow economy with the Statistica software package. The values of the Ease of Doing Business Index have been determined for the Donetsk People’s Republic. The taught neural network calculates the size of the shadow economy in the Donetsk People’s Republic and establishes that its size ranges between 30 and 40 %. The debatable issues of applying the suggested algorithm for calculating the size of the shadow economy in an industrial region are outlined. Conclusion. It is often not the irresponsibility of the entrepreneurs themselves that leads to the shadowing of the economy, but the difficulties with the business legalization and exorbitant taxes. The measures of minimizing the level of the shadow economy in the Donetsk People’s Republic are described. The suggested information will be useful for those who determine the economic policy of the region.

Introduction. The demand for hydrogen in the energy market is annually increasing, which is due to the need to reduce greenhouse gas emissions with the subsequent increase in the share of energy from renewable energy sources. The leading countries in the hydrogen energy market, which include China, the USA, Russia, Japan and the European Union, are extensively developing technologies for the production, storage, and transportation of hydrogen, expanding the areas of its use and sales. At the same time, a competent development strategy for the country’s hydrogen industry is the determining factor in the successful stimulation and selection of directions for hydrogen development and use. For Russia, the issue of designing a strategy for hydrogen energy is quite acute due to the lack of clear plans and applied mechanisms to stimulate the development of the hydrogen industry. Purpose. The paper aims at analyzing the directions and prospects for hydrogen energy development in the Russian Federation, taking into account international strategies for the development and stimulation of the hydrogen industry. Materials and Methods. The study analyzes and generalizes the results of domestic and foreign research, international reports and regulatory documentation in hydrogen energy development, as well as synthesizes the recommendations derived from the analysis for stimulating the development of hydrogen energy. Results. The key development strategies of leading countries for hydrogen energy mainly focus on the investments in new technologies, tax incentives to both hydrogen producers and those who use hydrogen as a fuel, as well as to the companies involved in the carbon capture, use and storage (CCUS) of CO2. Most of the strategies used abroad are currently absent in Russia. Conclusion. The prospects and directions for hydrogen energy development in Russia were determined, and the recommendations for further development of the hydrogen industry included: 1) compiling and updating a register of promising hydrogen projects; 2) participation in public-private partnerships and consortia for hydrogen development; 3) grants for scientific projects and tax benefits for hydrogen projects; 4) investments from legal entities; 5) working together with the Government of the Russian Federation to develop and update hydrogen strategy.

Published: December 2023

Рассмотрена проблема повышения точности настройки дугогасящего реактора за счёт улучшения помехоустойчивости устройства управления. Задача решена таким образом, что свободные колебания в контуре нулевой последовательности сети выделяются путём компенсации помехи с частотой сети, причём компенсационный сигнал формируется усреднением помехи в течение нескольких периодов до возбуждения свободных колебаний. Показано, что в результате среднеквадратичное отклонение случайной (шумовой) составляющей выделенного полезного сигнала уменьшается в 1,3 раза по сравнению с прототипом. Кроме того, в отличие от прототипа, обеспечивается возможность дальнейшего снижения уровня шума путём удлинения усредняемого фрагмента помехи.

Published: December 2023

Рассмотрена возможность использования адаптивных измерительных органов (ИО), контролирующих аварийные составляющие аргументов и модулей токов и сопротивлений, с позиции стабильности контролируемых параметров при различных влияющих факторах: режимах нагрузки, переходного сопротивления в месте повреждения. Метод исследования – математическое моделирование режимов электрических сетей с ответвительными подстанциями, алгоритмов функционирования измерительных органов тока и сопротивления. В результате исследования определены измерительные органы, имеющие наиболее стабильные характеристики, которые рекомендованы к применению в многопараметрических устройствах релейной защиты дальнего резервирования. В качестве критерия стабильности контролируемых параметров предложено использовать показатель стабильности (нестабильности). Коэффициенты нестабильности ИО, контролирующих параметры аварийных сигналов тока и сопротивления, находятся в диапазоне (2 – 12) % при изменении токов нагрузки до 130 % от тока КЗ трансформатора наименьшей мощности, что вполне приемлемо для резервных защит. Дополнительный эффект достижения стабильности контролируемых параметров измерительных органов может быть обеспечен за счет использования корректирующих сигналов, зависящих от параметров защищаемой электрической сети и ее предшествующего нагрузочного режима.

Рассмотрена задача линеаризации материального оператора, описывающего свойства электротехнической стали, в режимах однонаправленного периодического перемагничивания с учетом гистерезиса. Материальный и линеаризующий его операторы рассмотрены на множестве периодических по времени функций, определяющих состояние ферромагнетика, с основным периодом, соответствующим одному полному циклу перемагничивания. В соответствие этим функциям ставятся спектры, задаваемые наборами амплитуд гармоник, которые находятся в результате разложения определяющих функций в ряд Фурье. После перехода к спектрам решена задача линеаризации вектор-функции, описывающей материальный оператор. Ее аргументами служат гармоники одной из величин, определяющей магнитное состояние, значениями являются гармоники другой величины. Приведено решение задачи линеаризации функциональной зависимости, сопоставляющей описывающие состояния ферромагнетика спектры с использованием адаптированной модели материального оператора гистерезисного типа. Найдены допустимые изменения амплитуд гармоник спектров, при которых погрешность линеаризации не превышает заданной величины. Рассмотрены примеры применения разработанных численных процедур для линеаризации характеристик электротехнической стали, подтверждающие возможность их использования для анализа электромагнитного поля и нелинейных электрических цепей в периодических режимах.

Published: December 2023

Обосновано техническое решение, позволяющее повысить эффективность рекуперативного торможения электрического подвижного состава. Предложено для приема и последующего использования энергии рекуперации использовать инерционный накопитель энергии (ИНЭ), а в качестве электромеханического преобразователя энергии применить вентильно-индукторную электрическую машину (ВИМ). Конструктивные особенности ВИМ и принцип ее работы выгодно отличает ИНЭ от ближайших конкурентов с другими типами электромеханических преобразователей энергии. Раскрыты преимущества использования ВИМ в составе ИНЭ, представлены расчеты на прочность ротора ВИМ при высоких частотах вращения. При выборе ВИМ как объекта исследований использованы методы математического моделирования и теория электромеханического преобразования энергии. При расчетах на прочность использован метод конечных элементов, реализованный в программном пакете «COMSOL Multiphysics» для определения поля механических напряжений во вращающемся роторе за счет центробежных сил. Даны рекомендации по использованию ВИМ в составе ИНЭ, обосновано использование напряжения тяговой сети постоянного тока для питания обмотки статора ВИМ напрямую без понижающих преобразователей, приведено схемное решение силовой части. Выполнен анализ механической прочности ротора. Рассчитаны безопасные для работы ИНЭ частоты вращения по условиям механической прочности. Результаты анализа предложенного технического решения и выполненные расчеты на прочность дают основание для продолжения исследований и конструкторских проработок в целях обеспечения внедрения ИНЭ на электрифицированном железнодорожном транспорте РФ.
Экспериментальное исследование жёсткости выходной характеристики мостового преобразователя постоянного тока
Authors: Авдеев Борис Александрович , Вынгра Алексей Викторович
Published: December 2023

Мостовой преобразователь постоянного тока широко применяется в блоках питания, вторичных источниках электропитания, твердотельных трансформаторах. Обычно такие преобразователи имеют обратную связь по напряжению, которая поддерживает выходное напряжение в заданных пределах. Проведены экспериментальные исследования по определению жёсткости выходной характеристики мостового преобразователя. Выполнена экспериментальная установка по исследованию выходных параметров преобразователя. Разработана принципиальная схема установки, представлены её описание и паспортные данные всех элементов. На установке получены осциллограммы работы мостового преобразователя. Управление преобразователем осуществляется с помощью фазового смещения. Экспериментально сняты значения выходного напряжения и выходного тока при разных фазовых смещениях (90, 144 и 180°), разном входном напряжении (20, 40 и 60 В) и нагрузке (2 – 250 Ом). Полученные результаты представлены в виде таблицы и графических зависимостей. Рассчитана жесткость выходных характеристик. Показано, что частота коммутации в 5 кГц при напряжении 60 В и смещении в 180° является минимально допустимой, т.к. трансформатор будет работать в режиме, близком к насыщению магнитопровода. Применение напряжения 80 В приводит к резкому возрастанию входного тока. Увеличение частоты коммутации силовых транзисторов не сказывается на жёсткости выходной характеристики, если частота коммутации не превышает допустимую. Использование силовых выпрямительных диодов вместо высокоскоростных импульсных влечёт за собой проседание жёсткости, особенно на высоких частотах переключения. Исследования показали, что выходная характеристика мягкая и нелинейна при небольших значениях тока, когда преобразователь входит в режим прерывистого тока. В режиме непрерывного тока жёсткость сохраняется на уровне 2 – 3% вне зависимости от частоты коммутации, уровня напряжения и нагрузки. Жёсткость увеличивается с увеличением фазового смещения.
Pros and cons of corruption to income inequality: an extensive literature survey
Authors: BULUT Abdulkadir , ÇAVUŞOĞLU Tarkan
Published: December 2023

Corruption, a universal concept with deep historical roots, permeates societies and has varying implications on the economies. This study reviews the existing literature on corruption, with a particular focus on how corruption shapes income inequality, using an analogy of sand- versus grease-the-wheels hypotheses to explore the positive and negative aspects of corruption. Our aim is to contribute to the corruption literature by presenting theoretical and empirical insights in a clear and traceable manner. Previous studies on the relationship between corruption and income inequality have produced mixed results, which can be attributed to variations in data and methodologies. Some studies show positive associations between corruption and income inequality, while others show negative associations, echoing the controversy surrounding the sand- and grease-the-wheels hypotheses. However, there is also scant research suggesting a non-linear relationship between corruption and income inequality, characterized by an inverted U-shaped pattern. All of these diverse findings have important implications for policymakers, emphasizing the need for comprehensive reforms that address corruption and simultaneously tackle the immediate challenges faced by low-income individuals during the transitional period. In conclusion, this study systematically discusses the implications of these findings for policymakers and researchers, highlighting the relevance of this research for shaping effective policies and further investigations in this field.

Authors: Tenyi Ana , Milutinović Aleksandra , Nemeth Lidija
Published: December 2023

The dental pulp is a highly vascularized and innervated loose connective tissue surrounded by hard dental tissues – enamel and dentine. With the primary dentin formation and the closure of the root apex, the conditions in the dental pulp change and pulp tissue compliance are reduced. Endothelial cells of pulpal blood vessels are highly differentiated and are capable of adaptation to changes in the environment. We aimed to evaluate the phenotypic plasticity of endothelial cells of pulpal blood vessels in permanent premolars with open (N = 6) or closed root apex (N = 30). The pulp tissue was stained with hematoxylin-eosin (HE) for the histological analysis, and immunohistochemically for a cluster of differentiation 31 (CD31), a cluster of differentiation 34 (CD34), and for smooth muscle actin (SMA) to detect vessels with CD31, CD34, and SMA positive endothelial cells. We used the student’s t-test and Pearson correlation test for the statistical analysis. We found a significantly higher percentage of the vessels with CD31 (P = 0.005) and CD34 (P = 0.000) positive endothelial cells in the group of teeth with closed root apex compared to the group with open apex. A significant positive correlation between SMA positive and CD31 positive vessels (P = 0.003) and between CD31 positive and CD34 positive vessels (P = 0.031) was also found. We conclude that the endothelial cells of dental pulp vessels express a small amount of CD31, but have a pronounced expression of SMA and CD34, which indicates their progenitor potential and contractile ability.

Socio-psychological characteristics of the school environment are a significant factor in the formation of students’ values, behavioral patterns, ways of relationships constructing, as well as expectations from the future. The paper describes the process of developing and validating the Behavioral Norms and School Climate Questionnaire, which allows to assess the subjectively perceived quality of the school environment from the perspective of students’ psychological safety and well-being. The questionnaire differs from the other resembling tools primarily by its creating procedure: the expertise of practicing psychologists working with teenagers in Russian schools was the basis for its development. The questionnaire includes 22 items that make up three scales: “Deviant Behavior”, “School Well-being” and “Subjective Unsafety”. The sample included 4,776 respondents. The survey involved schoolchildren aged 9 to 18 from more than 35 regions of Russia. Confirmatory factor analysis and convergent validity analysis have shown that the questionnaire has a three-factor structure and is characterized by reliability and validity, allowing it to be used for research in the field of educational psychology. It can be used in screening studies to assess the school climate and the subjective well-being of schoolchildren. Also, this tool can be used in the designing of preventive programs and interventions aimed at reducing anxiety and aggressive behavior and improving the quality of relationships within the school community, and to assess the effectiveness of the impact. The questionnaire is characterized by conciseness and ease of use. It expands the possibilities of studying the contribution of the school climate to the effectiveness of the educational process and the students’ social adjustment in the educational environment.

At the current stage of socio-economic development, one of the key tasks is to ensure that education quality matches labour market expectations, and the industry of science and technology is no exception. Nowadays, there is no systemic evaluation and due regard of research staffing needs and competencies required in this field. Hence, the gap between the current level of human capital development and its necessary level is ever increasing. This study focuses on leading research teams working in the area of advanced manufacturing technologies. The main research methods are the following: publication activity analysis for organizations in the Ural Federal District (henceforth UFD) in the field of advanced manufacturing, bibliometric mapping for identifying research teams, a series of in-depth interviews with research team leaders, job postings analysis using HeadHunter website database. Key findings: 1) we developed a methodology to identify leading research teams in the UFD that possess unique research and technology competencies in the field of advances manufacturing technologies; such teams and their leaders were identified; 2) in-depth interviews with research team leaders allowed to determine the most sought-after competencies for young researchers; 3) we compared the results of qualitative analysis (the in-depth interviews) with the final list of required competencies obtained in the process of analyzing job postings in the area of advanced technology in the UFD using the HeadHunter website. Thus, we identified the pools of the most sought-after competencies for the research and manufacturing sectors in the field of advanced manufacturing technologies. Identifying the most sought-after and in-demand competencies in the  UFD leading research teams can inform decision-making on updating university study programmes to ensure that student training matches the needs of the industry of science and technology in the UFD.
Russian Youth Educational Choice Cultural Patterns: The Case of VET Choice
Authors: Павленко Екатерина
Published: December 2023

The aim of the study is to explore how adolescents make sense of various educational opportunities while making educational decision to go to college after grade 9. We seek to decipher which symbolic horizons adolescents derive from in order to shape their decision irrespective of grades or family SES. To do so, we draw on data from in-depth interviews collected in 2013 as part of the Trajectories in Education and Careers project. We find that, on the one hand, decisions about the choice of trajectory are not made randomly, solely because of grades, but at the same time they are not only rational. As a result, we identify 4 symbolic horizons of decision-making, which indicates the heterogeneity of cultural patterns of decision-making to leave school and go to college.
REAL LIFE DATA OF CHRONIC MYELOID LEUKEMIA PATIENTS IN ISPARTA
Authors: ARDOĞAN Murat , ÖZBALCI Demircan , ALANOĞLU Emine Güçhan
Published: December 2023

Objective

Chronic myeloid leukemia is a myeloproliferative

neoplasm with an incidence of 1–2 cases per 100

000 adults. Central to the pathogenesis of CML, is the

fusion of the Abelson murine leukemia (ABL1) gene

on chromosome 9 with the breakpoint cluster region

(BCR) gene on chromosome 22. The therapeutic

landscape changed dramatically with the development

of the tyrosine kinase inhibitors (TKIs). This “targeted”

approach altered the natural history of CML, improving

the 10-year survival rate to 80-90%. This study aims to

investigate the effective management of TKI treatment

and overall survival in “real-life” CML patients and to

discuss the results with current literature.

Material and Method

Fifty-eight patients who were diagnosed as CML

between 2000 and 2018 in Suleyman Demirel

University Hematology Department were evaluated.

Patients’ clinical and laboratory characteristics, clinical

and demographical features, treatment options, side

effects and responses were evaluated in this study.

Risk assessment and staging applied with World Health

Organization criteria and Sokal Hasford and Eutos

risk scoring system. We determined hematological,

cytogenetic and molecular response according to

European Leukemia Network criteria.

Results

The average age, male / female ratio and survival

rates were found similar to those in literature. The

age distribution (p = 0,001) and Charlson comorbidity

index (p = 0.005) and Charlson comorbidity-age index

(p = 0,000) had a statistically significant effect on

overall survival. Age distribution (p = 0,029), Charlson

comorbidity age index (p = 0,001) and major molecular

response at 12 months (p = 0,028) were found to have

a significant effect on disease-free survival. Major

molecular response at 12 months (p = 0,006) also

had a statistically significant effect on progression-free

survival. Reticular fiber grade did not significantly affect

overall survival, disease-free survival and progressionfree

survival of patients.

Conclusion

These results suggest that CML is generally well

managed with existing treatment options and that

death occur more frequently due to other medical

problems. In CML, Charlson indices have been shown

to be significantly associated with overall survival and

disease-free survival.

Published: December 2023

The manufacturing sector is presently in search of sustainable materials that are lighter in weight, readily available, biodegradable, and cost-friendly. Natural fibers are observed to bring unblemished advancement in composite materials. In this research, a novel hybrid composite material has been analyzed. The composite comprises two different natural fibers, kenaf and coir fiber, reinforced in epoxy matrix with nanofillers of calcium carbonate particles. The weight percent of kenaf and coir fibers is maintained at 5.7% and 10%, whereas nanofillers is varied as 0%, 2%, and 4%, respectively, in all three samples. The elastic characteristics like the Longitudinal Modulus, and Transverse Modulus, are evaluated for the proposed composite utilizing five different analytical models, and are also interpreted using Representative Volume Element (RVE) analysis. The analytical results of the proposed composite are correlated with the experimental work in the earlier research. The influence of nanofiller is investigated and it has been observed that the composite with a higher filler content of 4 percent attains enhanced strength than a sample with a lower filler content of 0 and 2 wt. percent. The transverse modulus is noticed to uplift by 16.88%, and the longitudinal modulus by 11.14% on the mixing of CaCO3 particles in coir kenaf composite. Also, the composite is analyzed for hybridization effect, which proves to be one of the most promising ways to improve the features of the hybrid composite.

Authors: Yüceer Deniz , Kılınç Güneş , Coşkun Keskin Sevgi
Published: December 2023

In this study, questions in 5th, 6th, and 7th grade social studies textbooks were evaluated using Gallagher and Aschner's question categorization to determine their level. A document analysis was conducted in this study. Descriptive analysis was used for data analysis. Depending on the Gallagher and Aschner question classification, four themes were identified: cognitive memory, convergent thinking, divergent thinking, and evaluative thinking. The ratio of questions to instructional time in the learning domains was evaluated to determine which level was most intensive. As a result, questions focus on cognitive memory and convergent thinking; divergent and evaluative thinking is undervalued; children's abilities in remembering, identifying, deciding, comparing, making connections, summarizing, offering examples, and interpreting are emphasized. In addition, the level of questions directed to children during and after instruction was found to vary and not be evenly distributed across learning areas.

In this study, the effect of bentonite (BT) and dolomite (DT) on the mechanical and microstructural properties of concrete was evaluated on nine mixes. Cement was replaced with bentonite and dolomite by weight with varying mix ratios. The mixes are divided as M1 (Control mix), M2 (2.5% BT), M3 (2.5% DT), M4 (5% BT), M5 (5% DT), M6 (10% BT), M7 (10% DT), M8 (2.5% BT and 2.5% DT), and M9 (5% BT and 5% DT). Concrete specimens were subjected to mechanical and microstructural analysis tests. Mechanical test results show that the addition of bentonite (2.5%, 5%, and 10% ) leads to an increase in compressive strength (6.31%, 8.94%, and 13.15%) respectively. Similarly, the addition of 2.5% and 5% dolomite enhanced compressive strength by 10.52%, and 8.94% respectively, however, the addition of 10% dolomite reduced compressive strength by 6.8%. Replacement of cement with dolomite and bentonite individually also showed a small contribution to flexural and split tensile strength. Microstructural analysis shows that the addition of bentonite and dolomite filled the microstructure and refined the internal pores contributing to compressive strength. In addition, the replacement of cement with bentonite and dolomite enhanced the formation of CSH gel.

The two most crucial factors that are constantly taken into account while developing or building any new infrastructure in this day and age are sustainability and resilience. In a similar manner, this project centers on the same idea of sustainability and resiliency in order to construct a 10-story structure that served the function of a multipurpose community center equipped with cutting edge technology and carefully selected construction materials in order to lessen the number of harmful emissions and to keep a balance in both the structural strength and the environment. The design process has involved choosing the primary building material, the type of construction used, the building plans, and the carbon footprints the selected building materials are generated. The building’s planned design also assessed for structural soundness, environmental sustainability, and resilience. The outcomes are compared to an existing structure in the same domain for the critical evaluation and effective decision-making. As a result, this compilation also includes a complete and in-depth analysis of how the suggested construction is more robust and sustainable. The preface also includes information on the building parts, such as the materials used to contrive the structural as well as the non-structural members. In the end, the suggested design is monitored based on its structural qualities to ensure its stability and resilience. In order to successfully propose a sustainable and resilient design for the building of a multipurpose 10-story community center, a comprehensive and optimal set of recommendations is provided.

Content management system NetCat 6 provides the development of adaptive websites with CSS3 layout for desktops and mobile devices. Websites are created in no-code mode based on ready-made components; a programming developer is provided with an API for creating components with new functionality. The possibilities provided by NetCat 6 are discussed on the example of a catalog of reconstructed houses with a geoinformation function. The development method consists in creating an interactive prototype of the site by a designer, with subsequent refinement of its automatically generated codes by a programmer. The site was created within the waterfall model of software development that turns project management to an unimprovable simplicity. The practical significance of the work lies in the application of the most predictable software development model in terms of time and cost to create a site with non-standard functionality and adaptive design. An improvement of the NetCat toolkit is proposed to increase the efficiency of the proposed approach.

В статье рассмотрены планиграфические элементы поселения Польце I польцевской культуры. В историографической части показано становление современного понимания географического и топографического расположения археологического памятника в окрестностях с. Кукелева, а также его сегодняшнего состояния. Сделан вывод о том, что, несмотря на разрушение пашней в 1968 г. этого памятника и находящегося рядом поселения Польце II, на них в перспективе можно будет продолжить исследования для получения новой информации. По опубликованным материалам, полевым планам из Архива и находкам из Фондохранилища Института археологии и этнографии СО РАН впервые сделан полный план раскопов на памятнике Польце I, где показано взаиморасположение исследованных жилищ. Рассмотрены некоторые их конструктивные особенности. Указано количество обнаруженных в каждом из 10 жилищ керамических сосудов. Последние располагались по периметру внутреннего пространства, оставляя свободными середину вокруг очага и проход к выходу. Основная масса сосудов была найдена в шести жилищах. В быту использовалась только малая их часть, большая же могла предназначаться для торговли и обмена. Обилие посуды (965 экз. без учета многочисленных отдельных фрагментов керамики) делает памятник основным источником по гончарству и хозяйственно-культурным отношениям. Пока однозначно не установлено, являются ли керамические сосуды продуктом собственного производства или привозным товаром.
Psychological Restoration and Nature Connectedness in terms of "Bottom-up" and "Top-down" Approaches to Understanding Interaction with Nature
Authors: Shatalova O.V.
Published: December 2023

Relevance. The article presents an overview of notions about the foreign environmental psychology constructs — psychological restoration and nature connectedness. The constructs represent the effects of person's relationship with nature and are thought of as a resource of health/well-being. Objective. To reveal general characteristics of the constructs and to analyze them from the point of view of the "bottom-up" (evolutionary-psychological) and "top-down" (constructivist) approaches to understanding the salutogenic effects of interaction with nature. Methods. Analysis and generalization of theoretical and empirical research within the framework of foreign and Russian environmental psychology. Results. The constructs are characterized using the following criteria: basic conceptual assumptions, specific constructs, measures, empirical support. The theoretical foundations of constructs and their role in empirical studies are considered from the point of view of "bottom-up" and "top-down" approaches. Based on the review, we identified a trend towards the integration of approaches, and highlighted points that should be taken into account when studying the salutogenic effects of interaction with nature. Among them are mediation and moderation schemes, which include variables of psychological restoration and nature connectedness, they are "predisposed" to support "bottom-up" and "top-down" assumptions, respectively. When studying restorative environments, it is worth predicting the likely influence of “top-down” variables: traits, values, attitudes. In Russian studies, mostly appears the construct of connection with nature
On Directed Length Ratios in the Lorentz-Minkowski Plane
Authors: Açıkgöz Abdulaziz
Published: December 2023

The linear structure of the Lorentz-Minkowski plane is almost the same as Euclidean plane. But, there is one different aspect. These planes have different distance functions. So, it can be interesting to study the Lorentz analogues of topics that include the distance concept in the Euclidean plane. Thus, in this study, we show that the relationship between Euclidean and Lorentz distances is given depending on the slope of the line segment. Following, we investigate Lorentz analogues of Thales’ theorem, Angle Bisector theorems, Menelaus’ theorem and Ceva’s theorem.

A number of new methoxy-substituted 4,6-diaryl-3,4-dihydropyrimidine-2(1H)-thiones (DH-Pyr-S, 17-28) were designed and synthesized by the reaction of methoxy-substituted chalcones (1–14) with thiourea using solid-phase microwave method (MW) in view of the structural requirements as suggested in the pharmacophore model for tyrosinase inhibition (TI). Synthesized compounds were assessed for their in vitro TI potential and compounds 16, 17, and 21 exhibited notable tyrosinase inhibitory properties at the concentrations of 31.86 ± 2.45 µM, 44.58 ± 0.46 µM, and 48.47 ± 0.66 µM, respectively. Compounds (16, 17, and 21) were exhibited experimentally more potent TI than the standard used in terms of the IC50 value (Kojic acid, 55.38 ± 2.30 µM; p<0.0001). Additionally, DPPH activity of 15-28 were evaluated and compound 17 showed the moderate DPPH activity (45.64 ± 0.34%). Binding affinities of synthesized molecules to the tyrosinase catalytic core were further investigated through in silico molecular docking studies using AutoDock Vina (version 1.2.5), discovery studio accelyrs (BIOVIA, Dassault Systèmes) and predicting small-molecule pharmacokinetic properties using graph-based signatures (pkCSM) programs were used for ADMET calculations. Among synthesized compounds 15, 21, and 24 revealed high binding affinity to tyrosinase active site with lowest binding free energy (ΔG) values of -7.9 kcal/mol, thereby outperformed kojic acid affinity. In conclusion most modeling results were in agreement with their experimental data, suggesting the TI potential of lead compounds.
