Relevance. The need in technical groundwater exploration to construct a groundwater well for water supply of the rotation village of the mining and processing plant "Svetlovsky" in the Bodaibo district of the Irkutsk region. The electrical resistivity tomography is a common method for studying the upper part of a cross section and is widely used in mineral prospecting, geological mapping, engineering surveys, hydrological and environmental studies. The application of electrical resistivity tomography in these conditions will allow substantiating the location of hydrogeological wells and boreholes. Aim. Assessment of the geological and hydrogeological conditions of the area of work for the prospect of extracting groundwater for technical water supply for the needs of the rotational camp. Objects. Bedrocks, which are characterized by high resistance values and are aquicludes; permeable low-resistance zones that are water-bearing rocks. Methods. Ground-based geophysical surveys using electrical resistivity tomography; two-dimensional inversion of ERT data and their interpretation taking into account engineering and geological data of drilling and the GIS complex. As a result of the engineering and hydrogeological surveys performed using ground-based geophysical surveys by electrical resistivity tomography, it was established that the aquifer system of fissured rocks of the Imnyakh suite of the Proterozoic sediment complex (PR2-3im) is represented by fissured limestones of various colours from grey to blueish, with bands of mica schist. Analysis of the study results showed that the thickness of the exposed sediments is up to 50 m, the groundwater level of the operating horizon is opened at depths from 21 to 28 m. They are covered with a complex of low-permeability sediments of thickness from 5 to 11 m that are presented by interbedding of dense grey limestones and black metasandstones.

Authors: Urazakov Kamil R. , Makarova Tatiana G. , Borisov Alexander O.
Published: June 2024

Relevance. Today oil production by installations of electric centrifugal pumps is one of the leading methods of mechanized oil production. The mechanized operation of hard-to-recover oil objects is complicated by the high viscosity of reservoir oil, the formation of wax-deposits in the wellbore. This leads to an increase in hydraulic resistances due to a decrease in the flow section of pipes and other pumping equipment components, a decrease in the productivity of wells and the efficiency of pumping production. In this regard, an urgent task is to develop and improve methods and devices for preventing deposits of wax-deposits in wells. Object. Downhole pumping unit for dosing reagent (inhibitor of wax-deposits) into the well, which is a combination of two technical devices – a pump dosing the reagent and a jet pump. Aim. To analyze the influence of the design parameters of the dosing unit on the efficiency of its operation (reagent consumption, liquid cavitation coefficient in the jet pump). Methods. Mathematical modeling of the operation of a downhole dosing unit for the supply of reagent, based on the application of the laws of conservation of mass and quantity of motion, as well as Bernoulli's law for a moving flow in a jet pump. Results. Based on the simulation results, the nature of the influence of the design parameters of the developed installation on the reagent consumption is established. It is established that the maximum flow rate of the reagent is achieved with a mixing chamber diameter of about 22 mm; an increase in diameter relative to the specified value leads to a decrease in the degree of local pressure reduction, a decrease in the diameter of the mixing chamber – a drop in flow due to an increase in the flow rate in the chamber and an increase in hydraulic resistance. It was found that an increase in the supply of electric centrifugal pumps in the considered range of 100–200 m3 per day has practically no effect on the reagent consumption when the mixing chamber diameter is more than 30 mm. It was found that at confuser length values exceeding 210 mm, the cavitation coefficient, regardless of the mixing chamber diameter, exceeds one, which indicates a smooth and uniform pressure reduction in the device body. In general, it is shown that by regulating the design parameters of a downhole metering unit, it is possible to ensure the required reagent consumption at a known electric centrifugal pump supply (well flow rate).
Arsenic accumulation in spolic technosols in the area of a large copper smelting plant in the Middle Urals
Authors: Shabanov Mikhail V. , Marichev Maksim S.
Published: June 2024

Relevance. The necessity to study arsenic behaviour in soils as one of the main pollutants of depositing environments in areas of mining and metallurgical industry. In recent decades, arsenic emissions into the environment have reached a huge scale, so this element attracts the attention of researchers around the world. But in spite of all the studies of this problem, there are still some aspects that need to be clarified to understand the geochemistry of arsenic. This paper deals with spolic technosols with critically high arsenic content in the soil profile with alternating water-logged and dry conditions. As one of the main soil-forming elements, orthosteins contain significant amounts of iron and manganese compounds and are capable of adsorption and involvement of the elements in nodule formation. Aim. To determine the influence of orthosteins on arsenic accumulation in soil subjected to intensive anthropogenic load. Object. Ortsteins spolic technosols in the zone of operation of copper smelting plant and background soils not exposed to pollution. Methods. Arsenic was determined by inversion voltammetry method. Morphological characterisation and patterning of the orthosteins were performed by scanning electron microscopy using a Thermo Fisher Phenom XL G2 Desktop SEM unit. Results. The study of morphological features of orthosteins revealed differences in soils subjected to greater anthropogenic load. Arsenic was not detected inside the orthosteins in all studied soils. Also arsenic concentrations in the total mass of ortstein is up to 40–50% of the soil mass. This fact indicates the accumulation of arsenic by surface adsorption and the appearance of orthosteins as a geochemical barrier. The data obtained in the course of this work can contribute to the search for ways to clean up soils contaminated with arsenic, as well as provide an understanding of the basic processes of the behaviour of this element in soil formation.
Impact of gas arising from gas hydrate decomposition on the effective permeability of bottom sediments of the Arctic shelf: a laboratory simulation
Authors: Baryshnikov Nikolay A. , Zenchenko Petr E. , Turuntaev Sergey B.
Published: June 2024

Relevance. The necessity to investigate the mechanism of gas (methane) flow occurring during decomposition of gas hydrate formations within the layers of bottom sediments. This process is evident through substantial releases of methane bubbles in extensive shallow regions of the Russian Arctic shelf and has the potential to alter the equilibrium of atmospheric methane, a critical greenhouse gas. Aim. To quantitatively investigate, within the context of gas transport in bottom sediments, the impact of free and bound gas within the pores on the nonlinearity of filtration flows. Methods. The model samples with filtration properties similar to those of the bottom rocks of the East Siberian Arctic shelf. During the experiments, a specific amount of gas was injected into the saturated model sample, followed by the measurement of its effective permeability during a slow decrease in pore pressure gradient. The obtained curve was interpreted within the framework of the threshold gradient model. Results. The experiments yielded curves showing the dependency of the threshold gradient magnitude on gas saturation for several samples. It was found that the threshold gradient linearly increases with the growth in gas fraction within the pore space. Already at a gas fraction of approximately 0.02, this value in the experiments reached 0.01 MPa/m, corresponding to the hydrostatic pressure gradient in water. This suggests that even areas with relatively low gas saturation may be impermeable to convective fluid flow. This possibility should be considered when creating models for bubble gas transporting through the rock layers of bottom sediments. Furthermore, the existence of gas-saturated zones with threshold gradients can significantly impact the vertical profile of pore pressure and lead to a reassessment of the depth of gas hydrate stability zones.
Improvement of technologies for recycling waste petroleum
Authors: Kulagina Tatiana A. , Dubrovskaya Olga G. , Zaytceva Elena N. , Krylyshkin Roman N.
Published: June 2024

Relevance. Currently, the rational and economical use of petroleum products is of particular importance. This applies, among other things, to all known types of oils. Waste oils entering the natural environment are only partially neutralized as a result of natural processes. Most of them are a source of pollution of soils, water bodies and atmospheric air, leading to disruption of the reproduction of birds, fish, mammals, and having a harmful effect on humans. Thus, the widespread problem of collecting and recycling waste petroleum products is a relevant, cost-effective and knowledge-intensive area; since with the correct organization of regeneration, the cost of recovered oils is 40–70% lower than the cost of fresh oils with almost the same quality. Aim. To improve the technology of recycling spent petroleum products in the conditions of the northern territories in order to achieve eco- and energy efficiency. After the regeneration stage, used oils can be used for their intended purpose – returned to equipment lubrication systems, this is up to 75–80% of the original amount of waste oil generated. The remaining, “unrecovered” amount of 20–25% is burned in the form of a water-fuel mixture at enterprises equipped with liquid fuel boilers. The information available in the literature is insufficient to create an effective system for the disposal of used oils and other petroleum products, especially in the circumpolar territories. A differentiated approach to the problem is required, taking into account the peculiarities of the climate, the remoteness of the Arctic territories from the transport infrastructure, with mandatory compliance with environmental standards. Methods. cavitation technology (i. e. cavitation effects) and the LSTM (Long Short-Term Memory) deep learning method for processing hydrocarbon waste using the example of industrial oil W30 and, accordingly, modeling the migration of pollutants from industrial objects in open natural water sources. Results and conclusions. The results obtained indicate that the integrated use of raw materials is the result of the most complete, economically and environmentally justified application of all advantageous components contained in raw materials, as well as in production waste. Any hydrocarbon waste can be considered as secondary material resources that can be used for economic purposes, partially or completely replacing traditional types of material, raw materials and fuel and energy resources, the main value of which is their constant reproducibility in the production sector.

Published: June 2024

Abstract. The study of pre-Jurassic deposits in the southwestern part of Western Siberia is highly relevant due to their potential of increasing hydrocarbon resources. These deposits are considered prospective targets for the discovery of hydrocarbon accumulations. Weathering crusts developed on the upper part of the Paleozoic rocks in the Tomsk region exhibit a complex composition and structure, reflecting the interplay of various factors, including primary sedimentary processes and later alteration processes, including fracture-controlled fluid flow and metasomatism.
Aim. To establish the characteristics of the mineralogical composition and structure of the Paleozoic weathering crust formations developed at the Kalinovoe oil-gas-condensate field. Methods. Optical microscopy, X-ray diffraction, scanning electron microscopy. Results and conclusions. The composition and structure of the deposits at the boundary zone between the Paleozoic and Mesozoic successions have been studied in detail in the section of one of the wells at the Kalinovoe oil-gas-condensate field. The factual material is represented by core and thin sections of weathering crust deposits. The primary rock-forming minerals are silica minerals (quartz, chalcedony and opal) and clay minerals, with a lesser amount of carbonate minerals (siderite). Different lithological units were identified based on the content of minerals and bioclast (radiolarians and sponge spicules), indicating their formation under marine conditions. The protoliths of the altered rocks were carbonate-siliceous rocks, argillaceous limestones, and radiolarian cherts, which as a result of multiple stages of hydrothermal alteration and metasomatic processes were transformed into argillaceous-silicified rocks. In these rocks, with intense post-alteration overprinting, good reservoir quality porosity can develop. This porosity includes biogenic voids, microcavities, micropores, and open fractures.
Estrechamiento bilateral peruano-británico en el sector infraestructura en el Perú entre 2017 y 2021
Authors: Herrada Ruiz Alvaro Alejandro
Published: June 2024

Este artículo explica las razones por las Perú y Reino Unido estrecharon su relación bilateral en el sector de infraestructura entre 2017 y 2021. Por ello, se plantea que la relación bilateral se estrechó desde la firma del primer contrato G2G para Lima 2019 a partir de factores a nivel del Estado peruano y británico. Por un lado, la votación del Brexit, proceso de salida del Reino Unido de la Unión Europea, significó la necesidad de promover la exportación de los bienes y servicios británicos a nivel internacional. En este sentido, en el Perú los británicos identificaron una oportunidad para atraer la importación de su experticia en el sector infraestructura. Por otro lado, respecto al lado peruano, se propone que la brecha de infraestructura en el país ha sido un asunto pendiente en la agenda pública. Se concluye que la relación bilateral se estrechó en el sector infraestructura, porque existió una necesidad de los británicos de mejorar su posicionamiento en el Perú a partir del Brexit y que coincidió con la visibilización de los problemas de infraestructura que enfrentó el Perú que generaron las condiciones para el estrechamiento.

Tajdîd al-Nahwi 'Inda Tammâm Hassân wa Atsaruhu bi Mâddati Ta'lîmi al-Nahwi li Ghairi al-Nâthiqîna bi al-Lughah al-'Arabiyyah
Authors: Bani Muhtarom Muslihudin , Bani Hafidah Hafidah
Published: June 2024

Nahwu science now contains philosophy so it is difficult to learn. In addition, the science of nahwu compiled by classical scholars reduces it to one qorinah or guidance, namely I'rob. In fact, most words in Arabic end with the letter 'Ilat which cannot be identified with I'rob. The aims of this research are twofold, namely (1) to explain the new theory in nahwu science which was carried out by Tammam Hassan. (2) explain its effect on nahwu learning materials for non-Arabic speakers. This research is the qualitative research, the type of research is library research. The result of this research is to offer Tammam Hassan's renewal of nahwu (tajdid al-nahwi), namely Qarain al-Lafdziyah. Its influence makes al-kalimat divided into seven, including: al-ism, al-washfi, al-fi'li, al-dhomir, al-dzorof, al-kholifat, and al-'adat. The era is divided into two, namely the al-Nahwi era and the al-Shorfi era. With these qarain (instructions), it greatly influences the broader and more understanding nahwu learning material . Therefore, it is very necessary for researchers, educators, and students to explore the renewal of nahwu knowledge in depth.
Tantangan Penerjemahan Arab-Indonesia Video Animasi Qisshah Al-Athfâl dalam Pendidikan Moral Anak
Authors: Mauidlotun Nisa  , Ulya Afifa
Published: June 2024

This article reveals the challenges of translating the Qisshah Al-Athfal animated video which was uploaded by Zad Al-Horof through his YouTube account as a moral education for children. Translating animated videos that adapt voiceovers is an option in presenting moral education to children because hearing is the first active sense, so it is stronger than reading skills. This article examines the process of translating the animated video Qisshah Al-Athfal uploaded by Zad Al-Horof and refers to the adaptation of dubbing with a cultural approach and sosiolinguistic. There were four translated videos, all of which were chosen because of the precarious and tense situation in the setting of the story. Secondary sources are taken from the literature of books relevant to the translation process, ranging from several Arabic-Indonesian dictionaries to authoritative articles to be associated with this study. From the research results, it was found that in the translation process, politeness in language as Indonesian culture is highlighted, especially in translating my pronouns into "mother", you become "sis" and so on as a form of Indonesian kinship culture. The communicative strategy in the form of removing (Hazf) and adding (Ziyadah) considers lip movements and the duration of the character's articulation. So, the conclusion is the challenge of translating the animated video of Qisshah Al-Athfal is an effort to present an Arabic cultural spectacle for Indonesian children who are able to provide moral education and politeness in children's language

В работе представлены результаты исследований прооксидантного действия ультрадисперсных частиц (УДЧ) титана при высоких дозировках (0,06–6 мг/дм3). В качестве тест-объекта использовали рыб Danio rerio. На 14-е сутки эксперимента наблюдалось снижение содержания малонового диальдегида (МДА). Увеличение сроков экспозиции привело к усилению продукции МДА, а также к снижению активности супероксиддисмутазы (СОД) во всех группах по сравнению с началом эксперимента, но при этом в опытных группах показатель СОД был выше контроля в 2,5 раза. Анализ активности каталазы показал существенное ее увеличение в течение всего срока экспозиции во всех опытных группах по сравнению с контролем. В конце эксперимента зафиксирована максимальная активность каталазы. Этот результат можно рассматривать как адаптационно-приспособительную реакцию организма на развитие оксидативного стресса, что подтверждает токсический эффект УДЧ титана при высоких дозировках.

This article succinctly summarizes key theories regarding labor migration in the context of innovation, providing an overview of high-skilled labor exchange through the attraction of scientific and technological personnel across nations. Additionally, the article reflects on how migration influences the development of Science and Technology, as well as its economic implications. To conduct this research, the authors employed two primary research methods, including qualitative research through in-depth interviews with experts and quantitative research by analyzing composite indices from reputable organizations specializing in migration and innovation. The article emphasizes three Asian countries: South Korea, China, and Japan, all of which have excelled in advancing and enhancing their levels of scientific and technological expertise, along with their strategies for attracting skilled personnel. Policies focusing on recruiting high-quality labor with advanced knowledge are identified as pivotal factors determining their progress in this field. Consequently, in collaboration with expert consultations, the authors propose insights into policies for attracting quality human resources in the field of Science and Technology in Vietnam. This is intended to provide essential information for the government, businesses, educational institutions, and civil society.
The problem of assessing the religious composition and level of religiosity of the population of countries and regions
Authors: Balabeikina Olga
Published: June 2024

The article identifies the main problems of the theory and practice of collecting empirical data, on the basis of which one can build objective judgments about the level of religiosity of the population and its religious composition. The advantages and disadvantages of a sociological survey, population census data, and official data provided by religious organisations as sources of this type of information are considered.
The Evangelical Lutheran Church of Denmark (ELCD) is chosen as an example. It is considered by the author as a constructive example of a majoritarian religious organisation, reflecting over the dynamics of several decades quantitative data on the number of adherents and the degree of activity of their religiously determined behaviour. In the regional aspect quantitative data on the absolute and relative number of participants in religious ceremonies, on the registration of births, marriages and deaths, etc. are reflected. Information on the number of baptisms, confirmations, weddings, funeral services is provided at the level of individual dioceses of church-administrative units at the regional level. Based on the obtained results, territorial differences in the level of religiosity of Danish residents are recorded. The minimum indicators characterise the capital region with a high share of migrants – representatives of non-traditional cultures in the population structure. At the same time, the high degree of religious activity of ELCD adherents distinguishes the territories of mainland Denmark remote from the administrative center (Viborg, Aalborg, Ribe).
The results of the analysis of initial data concerning the total number and share of baptisms, confirmations, church marriages and funeral rites performed in the ELCD in recent years confirm the general secular trends characteristic of the population of Western and Northern European, primarily traditionally Protestant countries. Official statistical databases of religious organisations, recording both membership in them and participation in religious sacraments and rituals, are positioned as the most representative source of initial information for solving the problem of identifying the religious structure of the population and determining the level of its religiosity. The considered example of collecting and processing information is effective, but at the national and regional levels it is implemented only in cases where the model of religious-state relations provides the appropriate tools.
The sociovital nature of religiosity in the everyday life of the Don Cossacks
Authors: Skorik Alexander , Shadrina Alla
Published: June 2024

The Cossacks are traditionally associated with the social stronghold of the Russian Orthodox Church, with a group of the most righteous champions of the Orthodox faith. However, the Don Cossacks went through a long historical path before they found themselves in the bosom of the Mother Church and became its modern defenders from unrighteous attacks. Faith for the Don Cossacks initially represented a broader concept of life than just a religious feeling, extending into mental models of behaviour, often being fixed exclusively in material objects, expressed in a rather situational pilgrimage. In the historical everyday life of the Cossacks, a rationalistic attitude towards religious faith, which is not typical for other social groups, can be traced. Such pragmatism stemmed from a special military type of religiosity, initially formed on the frontier territory of the Wild Field, where the origins of the Russian Cossacks were laid, from where through the centuries the Cossacks carried their noble attitude towards God and the Christian faith.
They had their own historical road towards the Orthodox church, much longer and more controversial than that of other groups of the Russian population, but this makes its final results no less significant. “The Second Sun of the Don” - the Ascension Military Cathedral in Novocherkassk - is historically the second of the three Patriarchal Cathedrals in modern Russia. But it was rivaled in architectural splendour and interior decoration by the St. Nicholas Old Believer Cathedral, which reflected by its very existence at the beginning of the twentieth century the strongest positions of the Old Believers on the Don, and in the church the service was led by the Old Believer Archbishop John Kartushin. Among the Don Cossacks, heterodoxy also became widespread, and among its historical examples, spirit bearers stand out, and today Kalmyk Cossacks remain committed to the Buddhist (Lamaite) religion. However, despite the existence of various variants of religious faith among the Don Cossacks, the positions of the Russian Orthodox Church today are dominant and unshakable on the Don.
Russia in the modern world: the potential of soft power
Authors: Andreev Andrey , Andreev Ivan
Published: June 2024

The article is devoted to a comprehensive description of the conceptual, institutional and technological aspects of the Russian strategy for building up and using so-called soft power. The authors proceed from the fact that the future of Russia as a world power depends significantly on its ability to generate and increase impulses of soft power. The article describes the dynamics of the process of reformatting Russia's soft power potential, starting from the collapse of the USSR in 1991 to the present day. The authors point out that the current state of the Russian Federation, being a successor state of the USSR, inherited the main components of the latter’s soft power, including its authority in the field of science and culture, the status of one of the founders of the UN, an extensive network of connections in the intellectual and political elites of various countries etc. However, the changes that took place in the country in the 1990s significantly influenced the image of Russia in the perception of the population of other countries, as well as the Russians themselves.
The article demonstrates that, contrary to the provisions and conclusions arising from the concept of soft power developed by the American political theorist J. Nay, the policy of rapprochement with the “civilised world” carried out in the 1990s did not lead to an increase in Russia’s influence, but rather had the opposite effect. In fact, this influence has dropped to historic lows. And only from the beginning of the 2000s, in parallel with the strengthening of the political foundations of Russian statehood, the situation began to change for the better, and the process of restoring those factors of “soft” influence that Russia could use began. The article provides a detailed overview of the main components of this process; based on empirical data, it characterises the relationship between positive and negative opinions about Russia in different countries and on different continents. The authors also provide recommendations for improving the strategy for the formation and use of soft power in modern Russia. In particular, in this regard, the authors of the article draw attention to the key importance of a comprehensive elaboration of images of the future and the conceptual foundations of the theory of socio-historical development, corresponding to the multifaceted challenges of the 21st century.
Professional and educational orientations of students as an indicator of subjectivity in the field of higher education (on the example of universities in Nizhny Novgorod)
Authors: Fatenkov Aleksey , Sitnikova Irina
Published: June 2024

The subject of research in this article is at the intersection of problem areas of subjectivity and the state of higher education in modern Russia. The authors strive to solve a twofold problem. Contextually, in a philosophical and sociological perspective, using the concept of “subjectivity indicator” and outlining its semantic boundaries, instrumentally link it with certain empirical methods and the factual data obtained from them related to the study of students’ professional and educational orientations. The area of subjectivity considered in this article borders on the lower level with the area of mediation, and on the upper level – on the personal area. The authors provide arguments in favour of the fact that sociological tools can be correctly applied to the study of subjective, but not personal qualities. The nature of the error when measuring the level of subjectivity in individuals and in social groups is also clarified. In the field of higher education, the level of subjectivity is determined by a combination of indicators from two components: faculty and student. The professional and educational orientations of students, according to the authors, can be considered as a reliable indicator of subjectivity in a given social group. For the empirical basis of the article a field study conducted at universities in Nizhny Novgorod has been used.
Using a questionnaire survey, we studied the motivations of students at leading universities in the city regarding obtaining higher education, choosing a university and the direction of training, as well as preferences regarding their future field of activity. As a result of the analysis, five groups of students with different motivational guidelines were identified. Three groups with a clear, fully realised vocational and educational strategy: with a focus on the demand for the profession in the labour market, on the advantages of higher education as such, on the realisation of their own abilities and inclinations (the latter is defined by the authors as an “authentically subjective group”). And two groups - with a vague, not quite consciously built professional and educational trajectory (with a drift from the pole of subjectivity to the pole of mediation). As a result of the study, a conclusion was made that the level of subjectivity among modern students is not high enough, and the social reason for this insufficiency is indicated.
