The article considers the problem of reducing the oxygen content in oxidation gases during the oxidation process in petroleum bitumen production. The increased oxygen content in the exhaust gases is a consequence of deficiencies in the oxidation apparatus. In bitumen production processes, a hollow oxidation column is used, its main disadvantage is the incomplete use of atmospheric oxygen during the oxidation process due to the small specific surface area of the phase contact. This factor, in turn, causes the possibility of coking of oxidation column walls, metal corrosion and explosion in the gas phase. The need to reduce the oxygen content in oxidation gases is determined by environmental standards, technological regulations and safety precautions of oil refineries. To ensure safety and prevent fires in the column during the oxidation process, it is necessary to control the oxygen content in the oxidation gases. This parameter is limited by technological regulations to 7–8 % vol.The study of the existence of a relationship between the parameters of the process and the construction of a mathematical model of the process is based on data from operator’s logs of a bitumen production plant, which, in turn, allows us to build the most accurate mathematical model for a specific refinery.Analysis of operator’s logs using statistical methods of data processing made it possible to bring existing data into the required system, to identify patterns and dependences of the oxygen content in oxidation gases on process parameters. During the study, both descriptive statistics and data analysis were carried out based on correlation and regression analysis. During the analysis, significant excesses of the oxygen content in the oxidation gases from the established safety standards were revealed.Based on the research and literature data on the process of petroleum bitumen production using correlation and regression analysis, a mathematical model describing the dependence of the oxygen content in oxidation gases on the process parameters has been developed. This model makes it possible to most accurately select the parameters of the oxidation process to maintain the oxygen content in the oxidation gases within acceptable limits.

Published: September 2024

The Fischer – Tropsch synthesis makes it possible to obtain various types of products depending on the catalyst used (linear long-chain alkanes, components of motor fuels, gases, heavy products). The article provides an analysis of the development of industrial Fischer – Tropsch synthesis technologies. The authors investigated the Fischer – Tropsch process on a model mixture consisting of carbon monoxide and hydrogen on a bifunctional zeolite-free catalyst consisting of a carrier – montmorillonite treated with sulfuric acid, intercalated with a polyvalent zirconium cation, promoted with a solution of cobalt nitrate and organometallosiloxane (ruthenium carbonophenylsiloxane), which allows to obtain components of motor fuels in one stage. The studies were conducted at temperature 210 °C (previously conducted experiments indicate that at this temperature the maximum yield of iso-paraffins is achieved) and pressures 4, 6, 8 MPa. It has been found that the highest yield of iso-paraffins is achieved at pressure 6 MPa. The analysis of the obtained gasoline fraction for compliance with State Standard 32513-2013 for motor gasoline has been carried out. It has been established that the product complies with environmental class K5 and can be used as a component of commercial motor fuel.

Published: September 2024

Research on the separation of emulsions based on «I20-A» grade industrial oil and oil from the Tumutuk field using polysulfonamide (PSA) membranes has been carried out. In order to intensify the process and increase resistance to oiling, polymer filters were treated with corona discharge plasma. It was found that as a result of the modification, the separation efficiency increased to ≈ 90 %, and productivity increased up to 10 times. The results of the study allow us to recommend the use of a proven membrane ultrafiltration method for treating wastewater from emulsified oils, for example, in the composition of used cutting fluids or cleaning solutions. Corona plasma treatment improves the efficiency and productivity of water-oil emulsion separation. It was revealed that when separating an oil-water emulsion, productivity as a result of membrane modification in most cases, contrary to what was expected, decreases. This circumstance is explained by the more complex qualitative and, accordingly, dispersion composition of oil, which contributes to clogging of filter pores. Thus, to purify water from emulsified oil with polymer membranes, it is necessary to provide an additional technological solution for pre-treatment of the mixture being separated in order to increase the service life of the filters.
Not Just the Soviet: Alexander Zinoviev’s Yawning Heights From the Perspective of Governmentality Studies
Authors:   Institute of Philosophy, Russian Academy of Science (RAS), Moscow, Russia, Pisarev Alexander
Published: September 2024

Article is devoted to the interpretation of Alexander Zinoviev’s early novel Yawning Heights in the post-foucauldian optics of governmentality studies. In the center of Zinoviev’s social ontology, which is preliminarily reconstructed, there is confrontation between non-moral egoistic social laws (sociality) and antisociality based on the moral effort of individuals to constrain sociality with the help of law, science, religion, art, and other forms. This is a universal explanatory scheme used by Zinoviev to explain the specifics of power and society in the city of Ibansk, where the events of the novel take place. Ibanskian society is a cynical society of the victorious sociality, and Ibanskian regime is its continuation. Hereafter the features of Zinoviev’s vision of power are outlined. The essence of Ibanskian regime is in the structure of everyday life, and not in repression as its extreme manifestation. It uses the internal processes of society associated with the action of sociality. This leads to an appeal to the optics of governmentality studies to analyze the functioning of power in the novel. The main features of the approach of governmentality studies and government as the conduct of conducts are revealed. Arguments are given in favor of the thesis that the Iban governmentality is related not only to the Soviet regime, but also to other, past and present societies. In this sense, its study can become a contribution to the historical ontology of ourselves. Next, Ibanskian governmentality is reconstructed with the help of Jon Elster’s study of logical traps at the base of the Ibanskian regime, in particular, the confusion of passive and active negations. The basic dispositions and principles of power, specific governmental techniques, such as delation, meeting and delegated silencing, are written out. The model of the subject produced by Ibanskian governmentality and possible ways to counter-conduct are revealed. Lastly this governmentality is discussed as a reaction to the introduction of cybernetics into government.
On the Inside of Maps: Critical Cartography

The article is devoted to the discussion of the key problems of critical cartography, to which the materials presented in this issue of Logos are devoted. At the beginning the main points of this problematics are outlined by analyzing Buchra Khalili’s art project The Mapping Journey Project (2008–2011). Then the idea of critical cartography is introduced. Firstly, the critique is aimed at the ideas of modern Western common sense and official scientific ideology, first of all professional cartographers themselves, about the map as a neutral and objective representation. Secondly, it is aimed at the ways, contexts and consequences of the production and use of the map in socio-political practices from colonization, wars and the reshaping of social communities to the management of territories, nation-building and routing. According to critics of cartography, maps record not the landscape as a concrete material reality, but a strictly defined set of relations to this reality, conditioned by social, political, cultural and economic realities. The map is an important part of broader communications and practices. Despite the relative conceptual autonomy of mathematical and technical constructions and actions necessary for the production of the map, it can in no way be considered as something autonomous. It is essentially instrumental, situational and has significance only to the extent that it is part of the broader systems in which it is functionally included. In this sense, the map can be represented as an object in the process of constant formation, it is never ready and always needs to be finalized. The map is the result of the work of many institutions, a large chain of collective actions from data collection and systematization to mathematical processing, layout and circulation. In conclusion, the semiological aspect of maps is discussed: it is defined by the syntagma of the route and the syntagma of the border. Therefore, if the map expresses itself, this statement has two modes — “travel” and “delimitation.”

Published: September 2024

Live-cell microscopy imaging typically involves the use of high-quality glass-bottom chambers that allow cell culture, gaseous buffer exchange and optical properties suitable for microscopy applications. However, commercial sources of these chambers can add significant annual costs to cell biology laboratories. Consumer products in three-dimensional printing technology, for both Filament Deposition Modeling (FDM) and Masked Stereo Lithography (MSLA), have resulted in more biomedical research labs adopting the use of these devices for prototyping and manufacturing of lab plastic-based items, but rarely consumables. Here we describe a modular, live-cell chamber with multiple design options that can be mixed per experiment. Single reusable carriers and the use of biodegradable plastics, in a hybrid of FDM and MSLA manufacturing methods, reduce plastic waste. The system is easy to adapt to bespoke designs, with concept-to-prototype in a single day, offers significant cost savings to the users over commercial sources, and no loss in dimensional quality or reliability. (The last step in this version contains a supplemental video with extra context and tips, as part of the protocols.io Spotlight series, featuring conversations with protocol authors.)
La cargotectura doméstica como tendencia. Entre moda, creatividad y sostenibilidad
Authors: Muñoz Pérez Laura
Published: September 2024

This article delves into the recent concept of cargotecture or container architecture, that is the architecture carried out in recent decades using disused industrial containers as tectonic exoskeleton. In particular and in this case, a generic review of different examples of domestic cargo is carried out, categorizing it according to its uses: individual or collective, permanent or temporary, urban or rural, etc. The study of the different cases also serves to analyze the specific characteristics of this type of architecture and discern between its qualities (low environmental and energy impact, speed of realization, mobility and dynamism, adjusted economic cost...) and its potential difficulties of use (feeling of temporality, aesthetic questioning…). However, the article tries to offer a broad approach to an architectural phenomenon that only gains prominence over the years and that, saving fashions and trends, seems destined to remain and persevere.
Leaving the Crow’s Nest: How Creative Co‐Creation Transcends “Us‐Versus‐Them” Experiences of Dutch Refugee Students
Authors: Drop Hanke , Hendriks Peter , Barry Oumar , Abdulsattar Rania
Published: September 2024

This article is based on five years of longitudinal participatory action research on how former pre‐bachelor programme students with a refugee background experience finding their way into Dutch higher education and society. The four‐member research team and authors (two of which were former refugees), found that refugee students face a significant barrier of “us‐versus‐them,” especially in an educational context. We explored how creative co‐creation contributed to rethinking difference and sameness in higher education by breaking through or transcending this divide. Creative co‐creation through play, storytelling, or constructing artefacts enables “alterity,” approaching the other from the other’s position. Movement and action help to shape the world around us: Connecting and shifting positions creates sameness while leaving space for difference. Creative co‐creation during our research process included making co‐creation artefacts and activities, thus involving outreach to broader audiences for engagement. In the research process, it became clear that successful participation matters to all students and provides more opportunities for all, not just refugee students. A new notion of “we” in Dutch higher education and society that does not perpetuate the divide between “us” and “them” requires a shared responsibility. Higher education needs the university authorities and the teachers to make room for student stories and should provide spaces for dialogue and community development.

Determination of the amount of damage caused to the land and soils of Ukraine by military actions: calculation methods and current issues
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, Pidkova Oksana M.
Published: September 2024

The purpose of the publication is to review the documents of the regulatory framework of Ukraine that address the issues of determining the damage caused to soils and land as a result of the armed aggression of the russian federation, and to highlight the topical issues of theoretical, methodological and practical nature related to the determination of such damage. The article considers military soil degradation as a set of degradation processes that develop in soils as a result of military actions. Together with other types of degradation, military degradation worsens the current ecological state of soils and soil cover of the state. The article discusses in detail the methods of determining the amount of damage caused to soils and lands (Order No. 197) and the land fund (Order No. 295) as a result of the armed aggression of the russian federation. Order No. 197 assesses the damage caused to soils and land plots as a result of soil contamination with substances that adversely affect their fertility and other useful properties, and contamination of land plots with foreign objects, materials, waste and other substances. Order No. 295 assesses the costs of reclamation of disturbed land, damages incurred by owners (land users) of agricultural land plots, and the costs of restoring reclamation systems. Determining the damage caused to the soils and lands of Ukraine as a result of military actions is a complex issue that goes beyond the developed methods of calculating the amount of damage. The article considers topical issues of large-scale soil surveys, soil grading, soil monitoring, training of specialists in the field of soil science, land management, and nature management in the context of modern challenges caused by the impact of military operations on the soil and land fund of the state, the importance of resolving above mentioned issues for establishing and determining the amount of damage caused to soils and lands as a result of military operations, and developing recommendations for their reclamation and post-war restoration.
To Turn Psychology “into a Science of the Living Human Beeing...”: On the Psychotechnical Character of Research of the A.N. Leontiev school of the 1940s.
Authors: Sokolova E.E.
Published: September 2024

This paper analyzes select 1940s works of A.N. Leontiev’s school of psychological thought in light of the methodological principles of psychotechnical cognition which F.Ye. Vasilyuk formulated on the basis of L.S. Vygotsky’s ideas about practice as a constructive principle of psychological science. The paper refutes the assertion that Soviet-era cultural and activity psychology had no psychological practice in its own right, and demonstrates that such practice did really exist, had a distinctly activity-oriented nature, and contributed to the advancement of the activity theory. It was the practice of movement recovery which the team of psychologists, put together by A.N. Leontiev, practiced at the military hospital in Kourovka, fusing “psychotherapy”, research, and education into an inseparable whole. We observe that unity in Z.M. Istomina’s 1948 research, discussed in this paper in light of the eight general principles of psychotechnical cognition identified by F.Ye. Vasilyuk. Revisiting the Leontiev school’s heritage is relevant in the context of the ongoing conceptual revolution in psychology, for many methodological principles and provisions of activity psychology were ahead of their time.
Telocytes and pathological histogenesis
Authors: Odintsova Irina A. , Berezovskaya Tatyana I. , Slutskaya Dina R.
Published: September 2024

The ultramicroscopic structure of telocytes and their role in various pathologies were considered based on the analysis of scientific materials contained in eLibrary.Ru, The Russian National Library, and PubMed. Telocytes are cells of mesodermal, origin which are part of polydifferon loose connective tissue. Characteristically, they have long processes called telopods, which form a network by connecting them to the surrounding tissue elements. They are also found in the composition of musculoskeletal regenerates and near some tissue stem and progenitor cells. Such an arrangement may be associated with their participation in local metabolic processes. Telocytes are mainly detected on histological preparations by electron microscopy, as well as immunohistochemical staining, light microscopy of semifine sections. Telocytes are assumed to be an active regulator of metabolic processes and a participant in pathological histogenesis in circulatory, respiratory, excretory organs, etc. Examples of diseases and pathological conditions associated with telocytes were presented. Most scientific publications are devoted to the study of the role of telocytes in circulatory system disorders. These cells are mainly localized in the connective tissue of the myocardium, located between the blood capillaries near nerve endings. Cell telopodia are often directed to the vasculature and nerve trunks. Researchers considered telocytes in the myocardium as key regulators of intercellular signaling, which has a significant effect on the functioning of the heart and reactive changes in its tissue structures. Further investigations and refinement of the localization and morphofunctional characteristics of this cellular differon under normal physiological conditions and in the presence of a pathological process were performed. Further clarification and refinement of telocyte functions will optimize the development of methods for correcting pathological processes, including using cell therapy.

The bacteriostatic effects of human umbilical cord-derived matrices and hydrogels were examined. The use of biomimetics based on the extracellular matrix of extraembryonic organs, including the human umbilical cord, is promising for regenerative medicine and tissue engineering. Cell-free products from the extracellular matrix of various human organs and tissues are resistant to intentional bacterial contamination. Two acellular scaffolds prepared using different human umbilical cord decellularization protocols and two derived hydrogels were evaluated for their bacteriostatic properties. Two clinical cases of the use of lyophilisates of umbilical cord-derived hydrogels were described. The compositions of human umbilical cord-derived acellular matrices and hydrogels were studied using biochemical analysis techniques. The sensitivities of Staphylococcus aureus and Escherichia coli to umbilical cord-derived matrices and hydrogels were assessed using culture techniques, and metabolic activities of bacteria were also examined. Human umbilical cord-derived acellular matrices and hydrogels consist of collagens and contain proteins and glycosaminoglycans. A significant bacteriostatic effect of hydrogels against Escherichia coli was detected during the first 16 h of incubation, regardless of the type of detergents used for their preparation. The matrices did not show a bacteriostatic effect, which indicates that the hydrolysis of structural components contributes to the release of substances with bacteriostatic activities. The effect was presumed to be due to the influence on the level of metabolic activity of microorganisms. The use of powdered lyophilized hydrogels derived from human umbilical cord as an adjunct to autodermal graft in the treatment of infected deep wounds in two volunteer patients promoted healing without infections. In general, the use of hydrogel lyophilisates from acellular human umbilical cord as an additional treatment allows for the engraftment of skin autografts and promotes the healing of extensive deep wounds at risk of infection.

Mechanisms of conversion, somatoform and psychosomatic disorders in adulthood and childhood-adolescence
Authors: Shaydukova Lejla K.
Published: September 2024

Conversion, somatoform and psychosomatic disorders have been the subject of study for many years. If severe conversion disorders were common among patients in the 19th century, somatoform and psychosomatic disorders were more common in the 20th century. They have not lost their importance at present time. The combination of theoretical and clinical aspects gives the problematic a stable relevance, therefore these disorders lead to the need for interdisciplinary interaction, psychological and psychiatric counseling. The article briefly reviews fragments of the history of studying conversion and somatoform disorders, modern concepts of somatoform and psychosomatic disorders and their features in childhood and adolescence in comparison with the mechanisms of neurotic disorders, as well as the pathodynamics of somatoform disorders. The concepts of the emergence of somatoform and psychosomatic disorders are presented — macrosocial and microsocial, individual and family, psychoanalytic and psychodynamic, allowing to assess the breadth of the range of the raised problems. From the standpoint of the systemic approach, a parallel with neurotic disorders is drawn, the similarity of the mechanisms of their formation is emphasized, and the community of models of family relationships through “neurotic” and “somatic” symptoms is indicated. Identification of the features of somatoform disorders’ mechanisms in childhood and adolescence also brings a certain novelty and explains the increase in the group of “frequently ill children”. The combination of theoretical (psychological) and clinical (psychiatric) aspects is an important factor in the unification of the raised topic, which is initially interdisciplinary. The practical value lies in the analytical and didactic presentation of the material, which can be used by various specialists.

Published: September 2024

BACKGROUND: Currently, researchers describe challenges in developing new treatments for fibrosis and cirrhosis: poor quality of preclinical models, insufficient trial duration, and lack of markers of therapeutic response. A separate task is to standardize the process of liver cirrhosis formation in preclinical trials, which is necessary to obtain accurate quantitative estimates in a short timeframe.
AIM: This study aimed to develop a mathematical model for the formation of liver cirrhosis during preclinical trials.
MATERIALS AND METHODS: Liver fibrosis and cirrhosis were induced in male Wistar rats using freshly prepared thioacetamide solution for 17 weeks. The area of connective tissue was determined as a percentage of the image area. The area of interlobular veins was measured in µm2. The numbers of cells expressing the FAP marker and the α-SMA marker were counted. The level of mRNA expression of the Vegfa and Yap1 genes was assessed by real-time polymerase chain reaction. A mathematical model for classifying observations into stages was constructed using multiple logistic regression with stepwise selection of predictors, followed by calculation of sensitivity, specificity, and area under the curve with a 95% confidence interval based on ROC analysis.
RESULTS: As a result of the analysis, a mathematical model of liver cirrhosis formation was developed. The model is based on the values of two indicators: FAP+ cells and Yap1 mRNA and demonstrated good quality. The resulting value of the area under the ROC curve of 0.883 suggests good results for classifying cases.
CONCLUSIONS: The mathematical model makes it possible to differentiate the stage of liver cirrhosis from the stage of fibrosis during preclinical studies. It provides a foundation for studying the pathogenesis of liver fibrosis and cirrhosis, identifying new potential molecular targets for antifibrotic therapy, and reducing the number of expensive, labor-intensive laboratory tests.

Authors:   The Korean Logistics Research Association, Park Jin-Hee , Hwang In-A
Published: September 2024

The aftermath of COVID-19 for more than two years and the rapid application of 4th Industrial Revolution technology led to an increase in online shopping and non-face-to-face environments, leading to a rapid increase in last-mile delivery. As a result, the labor intensity of courier workers increases, the loss and damage of couriers, and crimes against the weak occur, etc. As one of the ways to solve this problem, the installation and expansion of unmanned courier boxes is attracting attention. However, efficient use is low due to the inconvenience of unmanned delivery boxes rather than the convenience of doorstep delivery, and in many facilities operated by public institutions, various location factors are not properly considered, so the existing unmanned delivery boxes are not effective. It shows a minor problem. Against this background, the purpose of this study is to examine the extent to which existing unmanned delivery boxes meet various cognitive factors and present guidelines for location selection. The target area is an unmanned delivery box operated by public institutions in Busan. The location selection criteria were analyzed by selecting six factors, namely, the proportion of single-person households/female population/rows and multi-generational housing, and accessibility to security facilities/bus stops/subway stations, taking into account population characteristics, housing characteristics, and accessibility. Hot spots analysis was selected as the analysis method, and spatial analysis and mapping were performed through QGIS. As a result of the analysis, it was found that a certain portion of the unmanned deliveray boxes in operation were installed in locations with good location conditions, but the rest were installed in different locations, which halved their effectiveness. So far, the department in charge has been installing it at branches requested by the jurisdiction or at branches where space is available. However, based on the results of this study, it is necessary to consider installation at a more appropriate branch in the future, and in this respect, the value of this study is I guess there is.
An Analysis of the Operation Efficiency and Environmental Impact of Cargo at Incheon International Airport
Authors:   The Korean Logistics Research Association, Chen Jia-Rong , Lee Hyang-Sook
Published: September 2024

Airports have traditionally been studied for their operational efficiency, but few studies have considered their environmental impact. This study analyzed the operational efficiency and environmental impact of the world’s major international airports, evaluated the operational status of each airport by year, and suggested improvement measures and strategies from the perspective of Incheon International Airport. To this end, this study analyzed the yearly efficiency changes of 20 international airports from 2018 to 2022, and explored various factors affecting airport operations. The result found that Hong Kong International Airport, Memphis International Airport, Ted Stevens Anchorage, and Louisville Muhammad Ali International Airport have consistently maintained optimal scale efficiency. When looking at the changes in efficiency during the COVID-19 pandemic, this study found an overall decline in airport efficiency, followed by a gradual recovery in 2021. Incheon International Airport’s scale efficiency ranged from 0.635 to 0.762, which is relatively low and needs improvement. Meanwhile, the technical efficiency of 10 airports, including Incheon International Airport, achieved the optimal level. In order to consider the environmental impact, this study analyzed the landing and take-off of each airport as an undesirable output factor. Hong Kong International Airport, Ted Stevens Anchorage International Airport, and Louisville Muhammad Ali International Airport consistently achieved high efficiency, while Incheon International Airport, Miami International Airport, and Los Angeles International Airport showed a decrease in efficiency due to negative factors. This research suggested that efficient scheduling is more important than simply increasing the number of flights to reduce environmental pollution. The results of this study are expected to serve as an important basis for improving the efficiency of airports in the future.

Innovations in Electronic Control Units: Enhancing Performance and Reliability with AI (Revision-1)
Authors: Ravi Aravind , Shah Chirag Vinalbhai
Published: September 2024

As the automobile industry moves toward greater efficiency, safety, and autonomous operation, the demand for Electronic Control Units (ECUs) - the microprocessors controlling everything from engine functions to infotainment systems - has exploded globally. Currently, there are more than 200 million ECUs in the world, and that number is expected to rise to 700 million by 2030, necessitating enhanced ECU performance, reliability, and safety. However, the growing complexity of ECUs has ironically led to increased false alarms and failures, which in some cases have endangered user safety and privacy, causing heavy penalties for manufacturers. Although artificial intelligence (AI) and machine learning (ML) are showing promise in addressing ECU-related issues, existing methods remain insufficient. Manufacturers need to employ AI-driven, end-to-end, standardized solutions that help design, train, test, and deploy models without deep AI expertise and allow real-time runtime monitoring and retraining of the ECUs.Drawing on decades of experience in the electronics and automotive industries, as well as a track record of successfully deploying AI-based solutions in safety-critical systems like avionics and diesel engine control, a comprehensive method is proposed. It includes an array of novel functionalities that increase transparency, reliability, and safety while keeping development times low. Central to the method is a feature that creates an environment-sensitive digital twin of the ECU by assimilating data from ECUs and the vehicle, thus improving model fidelity and monitoring for unforeseen edge cases. The proposal is based on co-design and training of AI-based perception and prediction models, which can monitor the relevant environmental parameters both on-board and in the cloud. The on-board model is lightweight yet deterministic and can trigger warnings in case of model uncertainty and prediction errors, while the corrective action is taken by the re-licensed cloud-based model. A dataset of more than 33 million kilometers of driving from passenger vehicles in Northern Europe with SaaStronic and Focus models has been provided, using compute-efficient methods for interpretation and simplification of AI-based models.
