Published: September 2024

Le roman Un prêtre marié montre les problèmes de relations interindividuelles entre Jean Sombreval qui est un ex-prêtre athée  et les gens conservateur. Lui et sa fille ont dû faire face à la discrimination de la société à cause de son apostasie. Le but de cette étude est de décrire les formes de conscience individuelle et d'interaction sociale des personnages, ainsi que de décrire la forme de structure sociale de la société et de la culture objective telle que dépeinte dans le roman Un Prêtre Marié. La méthode de recherche utilisée est l'analyse descriptive. L'objet matériel de cette étude est le roman Un prêtre marié, utilisant l'approche de la micro sociologie de Georg Simmel. Les résultats de cette étude sont les manifestations de la conscience individuelle des personnages à partir des activités de sensibilisation qu'ils mènent, les formes des interactions sociales des personnages basées sur la forme, le type et l'interaction des groupes dyade-triade, la structure sociale et la culture objective qui sont dépeintes dans le roman Un prêtre marié. À partir de l'analyse des quatre principaux concepts de sociologie-micro sur le roman d'Un prêtre marié, on peut conclure qu'une différence dans une société homogène entraîne des problèmes d'interaction sociale. Cela peut arriver parce que la conscience de chaque individu qui ne reconnaît pas une différence due à la vie sociale et culturelle qui les domine ne reflète pas la diversité individuelle.

The BRICS+ Expansion, Global Trade Dynamics, and the Dedollarization Phenomenon
Authors: Lee Brice Tseen Fu , Sims Juan Pablo
Published: September 2024

This paper delves into the transformative role of the expanded BRICS bloc, referred to as BRICS+, in the evolving global economic landscape and its implications for dedollarization. The inclusion of nations such as Ethiopia, Saudi Arabia, Iran, Egypt, and the UAE diversifies the bloc's economic and geopolitical reach, extending its influence into new regions like Africa and the Middle East. The study underscores the potential of BRICS+ as a catalyst in the dedollarization narrative, driven by the desire for economic autonomy, geopolitical strategies, and hedging against U.S. dollar volatility. The analysis further explores the intricate relationship between the BRICS+ expansion, global trade dynamics, and dedollarization. The paper concludes by emphasizing the potential of the BRICS+ bloc to reshape global trade dynamics, influence trade policies, establish new trade routes, and foster regional connectivity, all while advancing the agenda of a more diversified and multipolar economic world order.

Authors: КАРАГЕДОВ Г.Р.
Published: September 2024

Проведена инфильтрация спрессованной матрицы из карбида бора расплавленным алюминием. Показано, что при внешнем механическом воздействии на алюминий, предположительно облегчающем разрушение оксидной пленки на расплавленном металле, температура начала смачивания карбида бора снижается с 1100–1200 до 830–850 С, что позволяет избежать образования карбида алюминия, ухудшающего механические свойства композитного материала. Получены плотные керамокомпозиты с плотностью в диапазоне 2.45–2.58 г/см3, твердостью по Виккерсу до 21 ГПа и трещиностойкостью на уровне 3.5–4.5 МПа•м1/2. Установлено, что, хотя углеродные нанотрубки и взаимодействуют с расплавленным алюминием, при температурах ниже 950 С заметное их количество за время инфильтрации сохраняется, что позволяет получить армированный нанотрубками композитный материал.

A compacted matrix of boron carbide has been infiltrated by molten aluminum. It is shown that under the external mechanical action on aluminium, presumably simplifying the destruction of oxide film on molten metal, the temperature of boron carbide wetting decreases from 1100–1200 to 830–850 °C, and this prevents the formation of unfavourable aluminium carbide that could worsen the mechanical properties of composite material. Dense ceramic composites with the density within the range of 2.45–2.58 g/cm3, Vickers hardness up to 21 GPa and fracture toughness at a level of 3.5–4.5 MPa · m1/2 have been obtained. It has also been determined that, although carbon nanotubes react with molten aluminium, a considerable amount of them is preserved during infiltration at temperatures below 950°С, which allows one to synthesise the соmposite material reinforced with nanotubes.

Современные тенденции развития структурной биологии делают актуальными исследования строения биомолекул в условиях, приближенных к естественным, т. е. непосредственно в живой клетке и при температурах, близких к физиологическим. Одна из перспективных технологий, позволяющих приблизиться к этому идеалу, – адресное введение спиновых меток (например, нитроксильных радикалов) с последующим исследованием методами импульсного электронного парамагнитного резонанса (ЭПР). На сегодняшний день наибольшую устойчивость в живых системах демонстрируют пространственно затрудненные нитроксильные радикалы пирролидинового ряда с четырьмя этильными группами при парамагнитном центре, но их релаксационные характеристики не позволяют проводить измерения методами импульсного ЭПР при температурах выше 80 К. Нитроксильные радикалы со спироциклоалкановыми фрагментами в окружении нитроксильной группы пригодны для измерений при более высоких температурах, но они быстро восстанавливаются компонентами живых систем. Пирролидиновые нитроксильные радикалы с двумя спиро-(2-гидроксиметил)циклопентановыми фрагментами сочетают высокую устойчивость к восстановлению с высокими временами спиновой релаксации при температуре 120 К и выше. В этой работе нами впервые получен и охарактеризован гидрофильный хиральный радикал этого ряда – (1R,5S,7S,8R,12S,13S)-12,13-дигидрокси-1,8-бис(гидроксиметил)-6-азадиспиро[4.1.4.2]тридекан-6-оксил.

Modern trends in the development of structural biology make it relevant to study the structure of biomolecules under the conditions close to natural, i.e., directly in a living cell and at temperatures close to physiological ones. One of the promising technologies that allows approaching this ideal is the targeted introduction of spin labels (for example, nitroxides), followed by investigation using pulsed electron paramagnetic resonance (EPR). Today, the greatest stability in living systems is demonstrated by sterically hindered nitroxyl radicals of the pyrrolidine series with four ethyl groups at a paramagnetic centre, but their relaxation characteristics do not allow measurements by pulsed ESR methods at a temperature above 80 K. Nitroxides with spirocycloalkane fragments surrounding the nitroxyl group are suitable for measurements at higher temperatures, but they are rapidly reduced by the components of living systems. Pyrrolidine nitroxides with two spiro-(2-hydroxymethyl)cyclopentane moieties combine high resistance to reduction with high spin relaxation times at a temperature of 120 K and above. In this work, a hydrophilic chiral radical of this series – (1R,5S,7S,8R,12S,13S)-12,13-dihydroxy-1,8-bis(hydroxymethyl)-6-azadispiro[4.1.4.2]tridecane-6-oxyl was obtained and characterised by us for the first time.

Вопрос применения композитных материалов на основе льда для строительства инженерных сооружений в сложных метеоусловиях в настоящее время остается малоизученным. При этом использование льда как строительного материала обусловлено простотой и низкой стоимостью изготовления. В свою очередь, лед может быть усилен различными дополнительными элементами, позволяющими изменить его физико-механические свойства в составе композитного материала. В работе представлены результаты экспериментального исследования поведения ледяных балок, усиленных армирующими элементами, при чистом изгибе. Для усиления использованы продольные стержни с разными физико-механическими характеристиками из стеклопластика и полипропилена. Выполнено сравнение полученных результатов с ранее проведенными экспериментами по нагружению ледяных балок, усиленных стальной арматурой. Сделан вывод об эффективности использования предложенных материалов для улучшения механических характеристик ледяного покрова и изучено их влияние на поведение образцов. Отмечено положительное влияние полипропилена на деформируемость образцов и их несущую способность. Предложена схематизация диаграмм деформирования ледяных балок при усилении стальной и стеклопластиковой арматурой, полипропиленовыми стержнями. Анализируется перспективность применения стеклопластиковых и полипропиленовых стержней в составе композита на основе льда.

To date, the issue of using ice-based composite materials for engineering constructions under harsh weather conditions remains poorly understood. Application of ice as construction material is favored by its ease of use and low manufacturing cost. In turn, ice can be reinforced with various additional materials that change its physical and mechanical properties as part of an ice-based composite material. The results of an experimental study of the behavior of reinforced ice beams under pure bending are discussed. As a reinforcement, longitudinal rods with different physical and mechanical characteristics made of fiberglass and polypropylene were used. The results of the study were compared with previous experiments on loading ice beams reinforced with steel armature. It is concluded that the proposed materials can be efficiently used to improve the mechanical characteristics of the ice. There is a positive effect of polypropylene on the deformability of the samples, as well as their bearing capacity. Schematic diagrams of deformation of ice beams reinforced with steel and fiberglass reinforcement and with polypropylene rods are presented. Prospects for the use of fiberglass and polypropylene rods in the ice-based composite materials are discussed.

Исследуется изменение инсоляции Земли по широтам и сезонам в отдельные геохронологические периоды голоцена. Проводится сравнительный анализ облучения в граничные годы геохронологических периодов голоцена с современной инсоляцией (2022 г.). Отдельно анализируется изменение летней инсоляции в полушариях в пределах голоцена. Получены количественные оценки изменения интенсивности облучения для геохронологических периодов голоцена и сравнительная оценка относительно современного облучения. Определены экстремумы летней инсоляции в Северном полушарии, с которыми синхронизируются глобальные палеогеографические события голоцена: переход от холодной плейстоценовой эпохи к теплой голоценовой и Малый ледниковый период. Показано, что изменение летнего облучения Северного полушария, определяемое характеристиками орбитального движения Земли, является фактором отмеченных глобальных палеогеографических событий, а ареной их возникновения и преимущественного развития является Северное полушарие Земли.

Changes in the Earth’s insolation by latitudes and seasons in certain periods of the Holocene are considered. A comparative analysis of insolation in boundary years of Holocene geochronological periods with modern insolation (2022) is carried out. The change in summer insolation in the hemispheres is analyzed separately. Quantitative estimates in the intensity of insolation’s changes in the Holocene are assessed with respect to the modern insolation. The extremes of summer insolation in the Northern hemisphere are synchronized with the global paleogeographic events of the Holocene: the transition from the cold Pleistocene epoch to the warm Holocene and the Little Ice Age. Characteristics of the Earth’s orbital motion have also been shown to control the Northern hemisphere summer insolation’s change, which is a factor of the noted global paleogeographic events.
LONG-TERM MONITORING OF THE ACTIVE LAYER THICKNESS IN TYPICAL TUNDRAS OF THE WESTERN YAMAL
Authors: ВАСИЛЬЕВ А.А. , ОБЛОГОВ Г.Е. , ШИРОКОВ Р.С.
Published: September 2024

Приведены результаты наблюдений за межгодовой динамикой глубины сезонного протаивания в доминантных ландшафтах типичной тундры на территории геокриологического стационара Марре-Сале (западное побережье п-ова Ямал). Показано, что максимальной реакцией на изменения климатических условий обладают дренированные ландшафты, а увлажненные и заболоченные ландшафты характеризуются сниженными темпами прироста глубины сезонного протаивания. Медленный рост глубины сезонного протаивания при наблюдаемом потеплении климата объясняется наличием высокольдистого горизонта в верхней части многолетнемерзлых пород, осадкой дневной поверхности, а также увеличением высоты мохового покрова. Неравномерный прирост растительности, в первую очередь мхов, формирует большую контрастность в пространственном распределении глубины сезонного протаивания. Для региональной оценки глубины протаивания предложено использовать средневзвешенную величину, учитывающую долю каждого ландшафта в общей ландшафтной структуре региона.

Data on the interannual dynamics of the seasonal thawing depth in the dominant landscapes of typical tundra at the Marre-Sale geocryological station (western coast of the Yamal Peninsula) are presented. It is shown that drained landscapes have the maximum response to changes in climatic conditions, while wet and boggy landscapes are characterized by the reduced rates of increase in the active layer depth. The slow increase in the depth of seasonal thaw during the current climate warming is explained by the presence of an ice-rich horizon in the upper part of permafrost, thaw subsidence, and an increase in the height of the moss cover. The uneven growth of vegetation, primarily mosses, creates considerable contrasts in the spatial distribution of the active layer depth. For a regional assessment of the thawing depth, the use of its mean weighted value with due account for the share of each landscape in the entire landscape structure of the region is recommended.

Изучены мерзлотно-гидрогеологические условия тукулана Махатта в Республике Саха (Якутия), где распространены мощные таликовые водоносные горизонты. В первой половине июля 2021 г. дебит источников ручья Мугур-Тарын составлял 690 л/с, что меньше по сравнению с данными 1973-1974 гг. (770-930 л/с). Современные данные подтверждают стабильность химического состава надмерзлотных и межмерзлотных вод обследованных песчаных массивов за последние десятилетия. По химическому составу воды источников гидрокарбонатные кальциево-магниевые с минерализацией 13-50 мг/дм3. По данным маршрутных наблюдений и материалов дистанционного зондирования выявлено, что за последние 40-50 лет площадь песчаного массива, закрепленная растительным покровом, увеличилась примерно на 18 %. Это привело к понижению температуры пород, изменению водно-теплового баланса массива и снижению водных ресурсов таликовых водоносных горизонтов.

A study of permafrost and groundwater conditions of the Mahatta Tukulan, Sakha Republic (Yakutia), where thick aquifer talik horizons are common, was carried out. During the first half of July 2021, the water discharge of the Mugur-Taryn Spring was 690 L/s, which is less compared to data from 1973-1974 (770-930 L/s). Current data confirm that the chemical composition of suprapermafrost and interpermafrost groundwater has been stable over the past several decades in the studied sand massifs. The chemical composition of these spring waters is calcium-magnesium bicarbonate, with mineralization of 13-50 mg/dm3. Using field observation data and results of remote sensing data processing, it was determined that the area of the sand massif with a vegetation cover has increased by approximately 18 % during the past 40-50 years. This has led to a decrease in soil temperature, a change in the water heat balance of the massif, and a reduction of water reserves of talik aquifers.

Представлены результаты исследований, проведенных на границе тундры и притундрового леса в Анабарском районе Республика Саха (Якутия) с целью изучения динамики мерзлотных ландшафтов и выявления влияния растительного покрова на температурный режим и глубину сезонного протаивания пород. Установлено зарастание Анабарской тундры лесом, рост которого совпадает по времени со вторым периодом длительного потепления Арктики (1979-2011 гг.). Вытеснение тундры лесом подразумевает также изменение мерзлотных условий района. По результатам исследования было установлено, что сезонноталый слой имеет наибольшую мощность на тундровом участке, с увеличением лесистости он уменьшается. Температура пород, напротив, имеет низкие значения в тундре, а в притундровых лесах температура мерзлых пород выше. В работе представлены результаты первого этапа исследования. На рассматриваемой территории планируются дальнейшие мониторинговые исследования.

The results of studies carried out at the tundra-woodland interface in the Anabar region of the Republic of Sakha (Yakutia) in order to trace the dynamics of permafrost landscapes and identify the influence of vegetation on the soil temperature regime and seasonal thawing depth are presented. The overgrowing of tundra with larch trees took place during the second period of long-term warming in the Arctic (1979-2011). The displacement of tundra communities by woodland communities has changed permafrost conditions in the region. Thus, according to our data, the maximum depth of seasonal thawing is reached in the tundra area; the depth of seasonal thawing decreases with an increase in the woodland density. On the contrary, permafrost temperature has minimum values in the tundra area and increases under woodland. In this paper, the results of the first - stage of the study are presented. Further monitoring studies are planned in the area under consideration.

Subject and Purpose. The effects considered concern phase synchronization of electrons in an ideal plasma subjected to the action of an external uniform, d. c. magnetic field. Two modes of the synchronization are discussed, specifically one by an external electromagnetic field and the other by the cyclotron radiation emitted by the electrons. The purpose is to compare these forms of synchronization and their effects on plasma stability. Methods and Methodology. The plasma is represented as a set of coupled oscillators whose dynamics is described via coupled differential equations. Assuming the coupling between the oscillators to be weak we find analytical solutions to the equation, further performing a stability analysis which exploits standard approaches of the dynamical systems theory. The solutions found are validated through corresponding numerical simulations. Results. As has been found, an external electromagnetic wave may be capable of guiding the particles toward phase synchronization, which can lead to formation of phased bunches. This mechanism of particle grouping may prove to be more efficient, in terms of scale times of synchronization, if compared with known mechanisms exploiting relativistic effects. Additionally, we show that the cyclotron radiation emitted by the charged particles (which is often disregarded because of its smallness) can lead to self-phase synchronization of the electrons. Moreover, should the density of charged particles in the ensemble be sufficiently high, an instability can arise, potentially disrupting the ensemble. Estimates have been provided of the level of random fluctuations capable of undermining the synchronization process and plasma dynamics stabilization. Conclusions. The most significant finding of this analysis is the emergence of low-frequency oscillations in the charged oscillators set, followed by an onset of the plasma instability when the plasma density exceeds a certain critical value. Within that scenario, the ensemble of oscillators sitting in the external magnetic field is no longer held together by the field. The effect should be taken into account in applications related to plasmas of a relatively high density.
The Need for Separate Testing with Acetylcholine for the Assessment of Endothelial Dysfunction and Coronary Artery Spasm
Authors: Sueda Shozo , Sakaue Tomoki
Published: September 2024

Intracoronary acetylcholine (ACH) testing is clinically useful to diagnose the presence of the coronary vasomotor disorders coronary endothelial dysfunction and coronary epicardial/microvascular spasm. In Western countries, continuous intracoronary injection of ACH for 2–3 minutes without a pacemaker is the usual method, while rapid injection of ACH for 20–30 seconds with a pacemaker is the traditional procedure in Japan. Coronary microvascular spasm is often observed in Western populations, whereas coronary epicardial spasm is frequently seen in Japanese subjects. Methodological differences between Western and Japanese protocols may lead to the opposite prevalence of coronary vasomotor disorders. This article discusses the optimal method for diagnosing endothelial dysfunction and epicardial/microvascular spasm based on previous reports, and compares intracoronary ACH testing performed by Western cardiologists with that by Japanese physicians.

In the steppe region an increase in the level of environmental pollution inevitably leads to a deterioration in the ecological condition of all components of ecosystems and leads to growth in the incidence of diseases among the population of the territory. It is possible to strengthen the natural immunity of the human body due to the introduction into the diet of products that contain biologically active compounds obtained from fruits, leaves, roots, etc. of representatives of the flora. Such plants include, first of all, representatives of the genus Rosa L. The high prophylactic and therapeutic effect of rose hips is confirmed by modern research by scientists. Among the vitamins that are part of the fruit, the highest content of vitamin C (ascorbic acid). Physiological and ecological studies of plants of the genus Rosa, in particular, indicators of success of introduction and vitamin C content, were carried out on the territory of the Botanical Garden of Oles Honchar Dnipro National University (DNU). It was found that due to their decorative properties and high-vitamin fruits, these plants are indispensable in the conditions of the steppe Dnieper region. Representatives of the genus Rosa are characterized by a variety of life forms and the specifics of the architectonics of the crown, the shape and color of the leaves and abundant flowering. It is shown that the climatic conditions of the new place of growth directly affect the growth and formation of shoots, and the annual cycle of plant development has its own characteristics, which are manifested during the growth of shoots, differentiation, the phase of physiological rest or forced dormancy depending on the geographical origin of species. Rose hips also differ in the size of fruits and seeds. Large fruit sizes and a significant number of seeds were observed both in the local species R. canina and in some introduced species of R. micrantha, R. iberica, R. hugoni. In the species R. multiflora and R. borboniana, small fruits and a small number of seeds were found. In this group of plants significant interest is associated with the high content of vitamin C in their fruits, which should not be destroyed during storage. As a result of our many years of research, it has been found that during fruit drying, there is a certain loss of ascorbic acid depending on the species characteristics of plants. The vitamin is best preserved in the fruits of R. rugosa (up to 58%) and R. hugonis (up to 55%). Other types are recommended to be used fresh. In addition, rose hips are highly decorative plants with long flowering and brightly colored fruits, which allows you to use this group of plants when creating compositions in modern landscape design.

The article presents a comprehensive characterization of the flora the valley-terrace landscapes of the Ukrainian steppe zone based on the results of systematic, geographical, biological and ecomorphic analyses. It has been established that the flora of valley-terrace landscapes is represented by 1315 species of vascular plants belonging to 508 genera, 120 families, 6 classes and 5 divisions. The spectrum of the leading families of valley-terrace landscapes of the steppe zone of Ukraine basically coincides with a similar spectrum leading families of vascular plants of southeastern Ukraine, the flora of the Right Bank steppe and of the Dniester-Tiligul interfluve. The only difference is in the Cyperaceae family, which ranks fifth in the spectrum of leading families, while in the above floras this family is on the 9th–10th places. The flora is dominated by hemicryptophytes among climamorphs, perennials among biomorphs, heliophytes among heliomorphs, mesotrophs among trophomorphs, mesophytes among hygromorphs, and pratants among cenomorphs. According to the cenomorphic analysis of the flora, it was found that 30.2% (397 species) have a ruderal component (found in ruderal, semi-natural habitats). The adventitious flora is represented by 223 species of vascular plants (16.96%), including 6 invasive species. From the flora of valley-terrace landscapes of the Ukrainian steppe zone, 8 species of vascular plants are included in the World Red List (WRL), and 14 species are included in the European Red List. The Red Data Book of Ukraine in different categories: (1) – 1 species, (2) – 25 species, (3) – 9 species, (4) – 7 species. The Red List of Dnipropetrovska oblast includes 42 species of the studied flora. The analysis of species occurrence categories revealed that 88 species are very rare, 495 species are rare, 286 species are sporadic, 368 species are frequent, and 78 species are very frequent. The analysis of landscape transformation according to the hemerobia system shows that mesohemorrhizal species predominate in the flora, which indicates an average level of transformation of valley-terrace landscapes of the Ukrainian steppe zone.
