The pro-oxidant-antioxidant ratio in the cells of plant seedlings from various ecological and geographical growth locations
Authors: Shashurin M. M. , Zhuravskaya A. N.
Published: October 2024

The balance of pro-antioxidants within the cells of common fir (Abies alba) and mugwort (Artemisia vulgaris) seedlings cultivated across eight distinct climatogeographical regions of Russia and Kharkov (Ukraine) was investigated. The intensity of lipid peroxidation processes was recorded as a pro-oxidant response, and the antioxidant response was measured by assessing the total content of low-molecular-weight antioxidants and the activity of superoxide dismutase. An assessment of the pro-antioxidant balance within the cellular structures of seedlings, originating from seeds of plants grown in diverse climatogeographical environments, was performed. This evaluation included the analysis of seedling survival rates, the degree of lipid peroxidation, and the activity of the antioxidant system, utilizing the coefficient method for measurement. The results suggest that the regions from which plant seeds were collected can be classified into three distinct zones according to the values of the extremity coefficient. A significant positive correlation was identified between the activity of superoxide dismutase in the cells of the examined seedlings and the levels of solar insolation in the regions where the seeds were collected. Adaptation changes in wild plants to temperature, humidity, and light conditions lead to the activation of antioxidant systems. The seedlings of plants whose seeds were formed in environments characterized by high insolation and low precipitation (such as Yakutsk, Ulan-Ude, and Srednekolymsk) exhibited a low total antioxidant content, accompanied by a compensatory increase in superoxide dismutase activity. Our research indicates that the survival rates of seedlings of common fir and mugwort are contingent upon the pro-antioxidant balance that has developed in response to the climatic conditions experienced by the plants. This relationship is characterized by species specificity, nonlinear dynamics, and is predominantly affected by the volume of precipitation received during the active growing season of the maternal plants.

This study investigates the genetic predisposition to anxiety and its impact on adaptation to the extreme conditions of the North-East region of Russia, particularly concerning the Yakut population. Special attention was given to the polymorphism of the serotonin receptor gene HTR2A (rs6311) and its association with levels of situational anxiety (SA) and personal anxiety (PA). The study involved 261 Yakuts (n = 261) who are permanently residing in Yakutia, do not exhibit any psychoneurological symptoms, and provided voluntary informed consent. Anxiety level was assessed using the Spielberger-Khanin scale. Genotyping was performed using PCR and RFLP, followed by detection through electrophoresis in an agarose gel. The findings indicate that the sample was characterized by a predominance of individuals with moderate levels of SA (60.9 %) and PA (57.5 %). However, in the group of women, individuals exhibited a high level of PA (53.8 %). The highest percentage of agreement in anxiety levels (69.7 %) was observed among individuals with moderate SA and PA. Given that the serotonergic system is involved in regulating behavior, emotions, and various physiological functions, and plays a crucial role in mitigating the negative behavioral consequences of stressors, a study on the polymorphism of the serotonin receptor gene HTR2A (rs6311) was conducted. The analysis of the distribution characteristics of the genotypes and alleles associated with the polymorphism of the serotonin receptor gene HTR2A (rs6311) in the Yakut population revealed a significant predominance of carriers with the homozygous genotype GG (60.2 %), and the G allele (0.782). Futhermore, when examining the distribution of allelic variants of the studied polymorphism based on the level and type of anxiety, it was observed that the AG and GG genotypes were more prevalent among individuals with high PA and low SA. These results confirm the significance of genetic factors in adaptation to the extreme conditions of the North.
Thermal cycles, structure and properties of welded joints in structural steels during welding in extreme cold conditions
Authors: Golikov N. I. , Sannikov I. I. , Semenov S. V. , Ivanov M. A.
Published: October 2024

The article summarizes research on the thermal cycles, structure, and properties of welded joints made from low-alloy and low-carbon steels during arc welding in sub-zero temperatures. This review aims to analyze previous research to create solid recommendations for welding steel bridge structures during winter conditions. The results of a comparison of experimental measurements of thermal cycles of welding samples with different sizes made at room and subzero ambient air temperatures (down to minus 50 °C) are considered. It is shown that in small plates with dimensions of 200 × 250 × 10 mm, due to more intense heat reflection from the edges of the specimen, the thermal cycles of welding at different temperatures do not differ significantly. In more massive samples (sized 450 × 250 × 10 mm), an increase in the cooling rate of the overheated welded joint area is observed compared to room temperature welding. The impact of hydrogen on the development of cold cracks in low-alloy steels during welding at temperatures below freezing is examined. Metallographic analysis has revealed that the structural changes that occur during the welding of various steel grades are notably different and are influenced by the steel’s chemical composition as well as the thermal cycle parameters of the welding process. Dilatometric studies indicate that variations in the levels of alloying elements within different grades significantly influence the kinetics of austenite transformation. Therefore, to identify the best welding techniques for subzero temperatures, it is essential to consider not just how heat disperses in these conditions, but also the kinetics of phase changes and their effects on the structure and properties of the products resulting from austenite decomposition.
Possible Contours of Developing International Trade in the Perimeter of Global Value Chains under the Conditions of New Reality
Authors: Maltsev A. A.
Published: October 2024

The transition from hyperglobalization to slowgbalization that began after the 2008 global financial crisis has increased skepticism about the future of globalization and motivation to adjust the architecture of international trade. The subsequent series of global shocks – the aggravation of the US-Chinese trade relations, the COVID-19 pandemic, the events in Ukraine in 2022-2023 – aggravated the situation, exacerbating the problem of stopping the negative consequences of the disruption of supply chains of goods and services. The purpose of the article is to clarify the contours of restructuring and outlooks for the development of cross-border trade in the context of new reality: the imposition of global shocks, increasing geopolitical uncertainty and increasing fragmentation of the world economy. The object of the study is the international trade in the perimeter of global value chains (GVCs), whose share in world trade increased from 34.93% in 1995 to 45.24% in 2007 and, after falling to 43.49% in 2020, quickly recovered and increased to 49.38% in 2022. The analysis of quantitative and structural shifts in GVC-trade was based on the methodology of structuring exports in the categories of value added by A. Borin and M. Mancini. The prospects for GVC-trade were assessed using the methods of identifying the “risk iness” of goods in the export-import turnover of S. Majune and V. Stolzenburg, the frequency of cross-border bilateral interactions of S. Liang, the agglomeration to global trade of K. Baris. The characteristics of the four main options for strengthening the resistance of GVCs in modern conditions are given – reshoring, diversification, regionalization and replication. The working hypothesis has been confirmed: all 4 considered trajectories are not mutually exclusive and none of them presupposes complete autarky of the country. The main conclusion is made, according to which the negative events in the global economy of the last decade reconfigured trade flows, accelerated the processes of regionalization of the global economy, but did not become a trigger for deglobalization.
The Transformation of International Relations in East Asia at the End of the XX – Early XXI Centuries
Authors: Verkholomov S. A.
Published: October 2024

The author examines the role of various institutions and countries in the transformation of the world order in East Asia during the period of the late XX – early XXI centuries. The work notes that at the end of the XX century, the American model of the regionalization process, carried out within the framework of Asia-Pacific Economic Cooperation (APEC), dominated. However, due to the changes in the US foreign policy doctrine and the Asian economic crisis of 1997–1998, APEC, in the early 2000s, began to give way to ASEAN+, where Japan occupied the leading position. Since the mid-2000s, China has been strengthening due to successfully carried out economic reforms and the use of various integration platforms. As a result, China began to promote its own model of globalization and regionalization in the region, which challenged the American order not only in East Asia, but also in the Asia-Pacific region. In the late 2000s, Washington sought to regain lost positions in the region by promoting the Trans-Pacific Partnership integration project, which intensified the struggle between the leading powers for dominance in the region. As a result, in the 2010s. ASEAN+ and Japan are developing the Regional Comprehensive Economic Partnership (RCEP) project, China is beginning to promote the Belt and Road international cooperation organization. As a result of the transformation of international relations caused by the movement of the world from unipolar to multipolar, there is a change in the transformation of the geopolitical situation in East Asia. The United States returned to the «traditional» methods of confrontation, increasing tension in the region and the world
Risks of Institutionalization of the Central Asia-China Format for Solidarity and Political Trust in the Shanghai Cooperation Organization
Authors: Vakhrushin I. V. , Nikolaev N. A.
Published: October 2024

The article considers the risks of institutionalizing the format of the Central Asia-China dialogue («C+C5») for solidarity and mutual political trust within the Shanghai Cooperation Organization (SCO). According to the documents, institutionalization is aimed at transforming the «C+C5» format into a full-fledged international intergovernmental organization with functions that duplicate the existing ones within the SCO. In the current official documents, Russia declares the importance of SCO development and assigns it a special role in the implementation of the «Turn to the East» Policy, the development of the «Greater Eurasian Partnership », and the deployment of the project of «the North-South International Transport Corridor». In this regard, further institutionalization of the «C+C5» format may create restrictions for the realization of these Russian plans and even for the protection of interests in the Central Asian region (CAR). This circumstance, coupled with the active attempts of the West and the United States to force a number of CAR countries to refuse Russia’s assistance in circumventing the sanctions regime is unlikely to be understood in Moscow. This means that it is necessary to think about the ways to overcome the likely limitations by deepening the dialogue with China on the issues of further development of the SCO and increasing its effectiveness. The plans to institutionalize the «C+C5» format may also cause increased opposition from other major global «players» such as the United States, India, the EU and Japan, which have been actively involved in Central Asian Affairs in recent years, developing formats for dialogue between «1 + C5» (CAR countries).

Published: October 2024

Under the pressure of the unprecedented economic sanctions, the Russian Federation faces the tasks of reformatting its foreign economic strategy, transforming its trade policy, changing supply chains, and expanding cooperation with the partners that maintain economic neutrality, particularly with the countries in Latin America, the Asia-Pacific region, and the Middle East. The purpose of this research is to determine to what extent economic sanctions can serve as a factor for activating trade and economic relations between Russia and the countries of MERCOSUR as the most significant potential partners from the Latin American region. The research question of the article is to what extent it is possible to sooth the impact of sanctions on the Russian economy by stimulating trade links with MERCOSUR countries. The article attempts to compare the relative significance of Brazil, Argentina, Uruguay, and Paraguay as trade and economic partners for Russia at the time of sanctions. The article identifies factors contributing to the growth of potential of mutual trade and economic cooperation and those constraining it; provides an assessment of the current development of trade and investment relations between the parties; calculates indicators to determine the possibility of substituting the lost markets for export-import operations by the new ones.

Published: October 2024

We collated (n=36) records of orca (Orcinus orca Linnaeus, 1758, also known as the killer whale (Cetacea Delphinidae) in the waters of the Republic of Fiji, South Pacific Ocean. Using standardised criteria, we classified these records into Confirmed, Presumed and Unconfirmed. We then conflated replicated records to create (n=12) unique meta-records between 1994-2024. We confirm, for the first time with photographs/video, the species as present in Fijian waters with evidence (photos/video) for (n=6) records between 2006–2024 which illustrate species-specific characteristics. From within that dataset, we report on a group of five orca which had either extremely faint ‘belt’ shaped saddle patches, or no saddle patches. Based on this pigmentation anomaly we consider that they may be an aberrant group or belong to a previously undescribed tropical ecotype.

INVESTMENT AND URBAN TOURISM INDUSTRY IN THE CITY OF CONSTANTINE
Authors: Haouari Souad
Published: October 2024

Global experiences have proven that tourism is one of the crucial economic sectors contributing significantly to the development process, owing to both material and non-material benefits it offers to host regions. Urban tourism, a contemporary type gaining momentum and support, has become increasingly popular in cities worldwide possessing essential tourism resources and attributes. This trend persists because urban tourism operates year-round, unaffected by seasonal or occasional variations.
Tourism has evolved into a cornerstone of urban economies, leveraging local potentials to generate sustainable profits and bolstering economic growth. This strategic approach enables cities to assume multifaceted roles supporting development through the utilization of these capabilities.
In this context, the concept of stimulating investment in Constantine's tourism sector, which encompasses all the elements necessary for urban tourism—including religious, heritage, and natural attractions—is pivotal. However, the oversight, lack of foresight, and absence of strategic development plans from local authorities have prevented this sector from fulfilling Constantine's esteemed position and potential. Consequently, this neglect has led to the squandering of a valuable economic asset that could otherwise bolster other sectors and drive the city's development.
To what extent and through what means can a sustainable tourism industry be cultivated in Constantine by capitalizing on its tourism potential?

FORMATION OF PROFESSIONAL AND ENVIRONMENTAL RESPONSIBILITY IN FUTURE ENVIRONMENTALS AS A SUBJECT OF COMMUNICATIVE INTERACTION WITH BUSINESS SUBJECTS
Authors: Kochubei Mykola
Published: October 2024

The article reveals the problem of the formation of professional environmental responsibility in future ecologists as a subject of communicative interaction with business entities. The categories “social environmental responsibility”, “professional environmental responsibility”, “positive individual professional environmental responsibility” were considered. It has been established that positive individual professional environmental responsibility differs from the above-mentioned qualities by a higher level of generalization, as it contains, in addition to legal and social aspects, an ethical aspect, which is the main motivated and natural regulator of individual behavior, striving for an ecologically appropriate, ecologically safe and healthy lifestyle for themselves, other members of society and nature. The structural and functional characterization of professional and environmental responsibility as a unity of three components: value, information-cognitive and behavioral. The definition of the concept of “professional and environmental responsibility of future ecologists” is presented as an integral, interactive, ethical and professionally significant quality of the individual, which manifests itself in the free choice of positive (useful for man, society and nature), ecologically appropriate, safe and competent activities in the system of “man-society-nature”, aimed both at its self-preservation and self-realization, as well as at achieving the strategic setting of the transition of humanity and the Earthʼs biosphere to sustainable co-evolution. It is inserted that the problem of formation of professional and environmental responsibility among future ecologists is fundamentally different from the problem of the functioning of the model of formation of professional and environmental responsibility in them as an expectation of the desired future. The structural and functional characteristics of the main construct of the developed model of the formation of professional environmental responsibility of future ecologists as a unity of three components are presented.

Authors: Tumanov V. A. , Proshin Yu. N.
Published: October 2024

A method for solving a self-consistent boundary value problem for the linearized Usadel equation is proposed. The method makes it possible to find the sample-normalized distribution of the superconducting order parameter and the critical temperature as functions of the problem parameters and to solve relatively complex spatially inhomogeneous problems, e.g., superconducting heterostructures containing inhomogeneous magnetic layers. Within this approach, layered structures containing superconducting and domain-split ferromagnetic layers are considered. The theory is compared with experiment for the Fe 20 Å/V 340 Å/Fe 8 Å/Cr/Fe 8 Å system.

Authors: Skripov A. V. , Babanova O. A. , Skoryunov R. V. , Soloninin A. V.
Published: October 2024

The dynamical properties of sodium closo-borate NaCB11H12 embedded into SiO2-based nanoporous scaffolds have been studied by nuclear magnetic resonance (NMR) and quasielastic neutron scattering (QENS) over wide temperature ranges. It has been found that a confinement of the closo-borate in nanopores suppresses the order-disorder phase transition, retaining the orientationally disordered phase with high reorientational mobility of the anions and high diffusive mobility of the cations down to low temperatures. This paper is based on the presentation at the RNIKS-2023 conference.
Oral microbiome in the development of oral cancer
Authors: Kolegova E. S. , Schegoleva A. A. , Kononova L. A. , Denisov E. V.
Published: October 2024

Oral cancer is an aggressive and rapidly progressive disease. The oral cavity is home to over 700 species of microorganisms which regulate metabolism, immune function and health. There are 3 types of mechanisms by which bacteria may participate in carcinogenesis. First, bacteria cause chronic inflammation, which stimulates the production of cytokines, including interleukins, interferons, and tumor necrosis factor. Second, bacteria can interact directly with host cells by secreting toxins or by binding to membrane receptors. Finally, the production of metabolites by bacteria may also contribute to carcinogenesis. The importance of bacteria level and composition in the transition of oral precancerous lesions to cancer has been demonstrated. The relationship of changes in microbiome composition with smoking, inflammation in healthy individuals, as well as with the development of oral cancer in patients has been studied.

Multiple exogenous or endogenous factors alter gene expression patterns by different mechanisms that yet are poorly understood. We used RNA-Seq analysis in order to study changes in gene expression in melanoma cells capable to vasculogenic mimicry upon action of inhibitor of vasculogenic mimicry. Here, we describe that the drug induces a strong upregulation of 50 genes controlling cell cycle and microtubule cytoskeleton coupled with a strong downregulation of 50 genes controlling different cellular metabolic processes. We found that both groups of genes are simultaneously regulated by multiple sets of transcription factors. We conclude, that one way for coordinated regulation of big groups of genes is the regulation simultaneously by multiple transcription factors.

Titin is a multidomain protein of striated and smooth muscles of vertebrates. The protein consists of repeating immunoglobulin-like (Ig) and fibronectin-like (FnIII) domains, which are β-sandwiches with a predominant β-structure, and also contains disordered regions. In this work, the methods of atomic force microscopy (AFM), X-ray diffraction and Fourier transform infrared spectroscopy were used to study the morphology and structure of aggregates of rabbit skeletal muscle titin obtained in two different solutions: 0.15 M glycine-KOH, pH 7.0 and 200 mM KCl, 10 mM imidazole, pH 7.0. According to AFM data, skeletal muscle titin formed amorphous aggregates of different morphology in the above two solutions. Amorphous aggregates of titin formed in a solution containing glycine consisted of much larger particles than aggregates of this protein formed in a solution containing KCl. The “KCl-aggregates” according to AFM data had the form of a “sponge”-like structure, while amorphous “glycine-aggregates” of titin formed “branching” structures. Spectrofluorometry revealed the ability of titin “glycine aggregates” to bind to the dye thioflavin T (TT), and X-ray diffraction revealed the presence of one of the elements of the amyloid cross β-structure, a reflection of ~4.6 Å, in these aggregates. These data indicate that the “glycine-aggregates” of titin are amyloid or amyloid-like. No similar structural features were found in titin “KCl-aggregates”; they also did not show the ability to bind to thioflavin T, indicating the non-amyloid nature of these titin aggregates. Fourier transform infrared spectroscopy revealed differences in the secondary structure of the two types of titin aggregates. The data obtained demonstrate the features of structural changes during the formation of intermolecular bonds between molecules of the giant titin protein during its aggregation. The data expand the understanding of the process of amyloid protein aggregation.

The study attempts to investigate created within the framework of other denominations sources of Simeon’s Polotskij two sermons: «Slova o perenesenii Ubrusa iz Edessy» (Sermon to a feast of the Mandylion’s translation from Edessa) from sermon’s collection «Vecherya Dushevnaya», 1683 and interpretation of the evangelical parable of the Good Samaritan from collections of homilies «Obed dushevnyj», 1681. The study confirms existed in the literature disparate observations about the significant commonality of the sources of inspiration and factual material of Simeon’s collections and his poetic encyclopaedia «Vertograd mnogotsvetnyj» (A Garden of Many Flowers; Latin poetry sources identified by Anthony Hippisley); in particular, that in both cases Simeon used Latin collections of annual sermons by Bavarian Jesuit Matthias Faber (1586/87–1653). The techniques of translation of Latin sermons were also investigated: these techniques give the reader (researcher) the impression that in one case the biblical fragment of Song of Songs (5:10–16) acts as the structuring text for Simeon’s «Slovo», and in the other case – interpretation of the evangelical parable of the Good Samaritan by John Chrysostom, while Simeon both compositionally and textually reproduces homilies written by Faber and his elder fellow of the Jesuit Order, Spanish exegete Alfonso Salmerón (1515–1585).
Functional and Stylistic Equivalence by Translating the Facts of Code-Switching (on the Material of Russian Verbs in the Polish «Version R» of A. Burgess’ Novel «A Clockwork Orange»)
Authors: Ostapchuk Oxana A.
Published: October 2024

The article is devoted to the analysis of Russian verb inclusions in one of the Polish versions of the translation of A. Burgess’s novel «A Clockwork Orange» under the title «Mechaniczna pomarańcza. Wersja R» (1999) by R. Stiller. The Russian language is deliberately used by the translator to construct a special «slang» Nadsat in its Polish version in order to give the text an appropriate expressiveness within the language play. 117 verbs selected from the 1,000-item Dictionary of «Unintelligible Words» accompanying the translation represent Russian-Polish code-switchings and other hybrid contact phenomena. The analysis is intended to reveal the functional and stylistic equivalence of the translator’s strategies of introducing Russian verbal borrowings in the Polish text on the formal, semantic and communicative levels. Verbal borrowings of Russian origin are classified depending on the strategy of their incorporating into the text, as well as the degree and level of its adaptation.
Childhood Memory of Adult History. Holocaust Trauma and Migration in Z. Oryszyn’s novel «Saving Atlantis»
Authors: Adelgeim Irina E.
Published: October 2024

Zyta Oryszyn’s (b. 1940) novel «Saving Atlantis» (2012), like almost all of her work, is born of a sense of guilt – a desire to «cover with words» the pain caused by childhood memories of the trauma of participation (unwitting complicity in the expulsion of Germans from the Regainde Lands), the trauma of witnessing (the Holocaust) and the trauma of inheritance (family memory of forced migration). Children’s consciousness, adapting to adult reality, accommodates the experience of power and powerlessness, of invader, victim and witness. From this position, the novel explores – in all its fragmentation – the autobiographical memory of the former German space functioning in the paradigm of violence, a space traumatising and generating a sense of unrootedness. The dramatic stories of several families, told from different perspectives, intersect and intertwine, forming a sorrowful labyrinth of fear, resentment, orphanhood, humiliation, and insurmountable alienness.
The Trauma of Emigration: Language Change (B. Stanišić, V. Čolić, A. Mahmutović, A. Božičević, N. Kulidžan)
Authors: Shatko Evgenia V.
Published: October 2024

The article is devoted to the problem of choosing a language among modern writers – immigrants from the countries of the former Yugoslavia and it presents four options for «life in another language». A number of authors continue to write in their native language, their works, however, are published, more often in translation into the language of the country of residence, the second category of authors are those who have completely changed their native language to the language of the country of residence, and still others begin their literary career in a non-native, acquired language – the language of the country residence, the last group, the smallest, are authors who began their literary career in a non-native language and, at the same time, not in the language of the country of residence. Loss of home, severance of ties with the homeland, isolation from «one’s own» culture and language are perhaps the most common motives in the texts of migrant authors. Creativity becomes for them a way to reflect on the events of the past (the trauma of war, loss of home) and the present (attempts to adapt to new conditions), which can be interpreted in terms of the therapeutic function of writing as an attempt to overcome trauma. The new space and time gap create a distance that allows one to turn to the inexpressible experience and try to narrativize it. Choosing a non-native language can also create (additional) distance, a mask.
ЗАСТОСУВАННЯ НЕЙРОМЕРЕЖ YOLO В СИСТЕМАХ АВТОМАТИЗОВАНОГО КОНТРОЛЮ ЯКОСТІ ПРИ ВИЯВЛЕННІ ДЕФЕКТІВ ВИРОБІВ ОРГАНІЧНОГО ПОХОДЖЕННЯ

Візуальна інспекція є невід’ємною складовою контролю якості продукції виробництва. Системи машинного зору широко використовуються в різних промислових галузях, займаючи важливе місце в сучасних системах контролю та перевірки якості. Це пов’язано, перш за все, з високим рівнем конкуренції на ринку і зростаючими стандартами до якості продукції. Справжнім викликом став процес контролю якості виробів органічного походження засобами машинного зору, зокрема з використанням нейронних мереж, адже такі вироби містять багато різноманітних дефектів і кожен виріб є унікальним, не схожим на інший. Для вирішення цих задач пропонуються застосування комплексного підходу, а саме технології локалізації та класифікації дефектів виробів засобами нейронних мереж.
Self-quotation in Personal Creation. The Journey from Musical Self-Portrait to #Selfie
Authors: Ulubeanu Sabina
Published: October 2024

Music composition is an art that allows the creator to encapsulate her/his personality and conceptions in an abstract manner, as well as to mirror his whole being into the music, like in a self-portrait. A single musical theme may be both the key to the evolution of the compositional techniques and a witness to the inner self transformations that occur during one’s life. This study follows a theme and some of its iterations in other personal works over the last 25 years in order to capture the relation between life, creation and compositional traits, using the concepts of time and memory to explain the evolution of my own musical language.
