Citizenship and Fatherland in the New Testament
Authors: Simonov V. V.
Published: May 2024

Christianity, as a set of ideas and an institutional state, is formed in the practical vocabulary of its time — the early principate, the semantics of which is influenced by the meaning of some terms and their use, established and wellestablished in the era of Hellenism.The article examines the change in the category of citizenship, which lost its original meaning in the dominant era, with a change in political practice, and almost completely lost its meaning in the Middle Ages, with the radical transformation of the foundations of social organization in the European civilizational area.

Published: May 2024

Abstract This study presents findings from research conducted with indigenous and peasant students (n = 53) in their first year of the Rural Education Degree (Countryside Education) program at a public university in the Brazilian Midwest. We investigated previous knowledge and methods for developing entomological knowledge using structured questionnaires with open, closed, and multiple-choice questions. As a result, we discovered 24 distinct types of animals known as insects. Indigenous peoples conceptualized insects using ecological principles, whereas peasants approached the subject from health and emotional perspectives. Our findings revealed that indigenous students’ prior entomological knowledge was primarily developed within their families, while peasant students developed it at school. This study provides important insights into pre-existing knowledge and the development of entomological understanding in an intercultural setting. It encourages reflection on the interactions of traditions, folk knowledge, and scientific understanding.

Published: May 2024

This paper presents an analysis of the ultimate strength of a light-rail hybrid cable-stayed bridge (CSB) and discusses the influences of the concrete tension softening effect (CTSE), which is defined as the tensile strength of concrete being much less than its compressive strength. Both geometrical and material non-linearities are considered. A finite-element model of the bridge was established using Ansys software, with material non-linearity considered through the fibre beam element Beam189. An algorithm was written using Fortran language for the uniaxial concrete constitutive model to consider the CTSE (i.e. the concrete smeared crack model). The results showed that the CTSE significantly influenced the ultimate strength of the investigated bridge when the side-span concrete girder dominates the failure of the bridge as estimated by calculations. It is essential to consider the CTSE for the evaluation of the ultimate strength of a light-rail hybrid CSB.

Published: May 2024

Unintended subdural anesthesia accompanied by air bubbles compressing the cauda after attempting epidural anesthesia is rare. A 41-year-old pregnant woman was scheduled to undergo epidural anesthesia for cesarean section. After attempting epidural anesthesia, she experienced prolonged hypotension and recovery time, especially in the right extremity. Through magnetic resonance imaging (MRI) we found subdural air bubbles compressing the right side of the cauda equina in the L3 region. Thus, we considered unintended subdural anesthesia and performed conservative management with close observation. Her symptoms completely resolved within 24 h. Here, we report a case with various features of subdural anesthesia and subdural air bubbles compressing the cauda.
Use of vasopressors to manage spinal anesthesia-induced hypotension during cesarean delivery
Authors: Park Hee-Sun , Choi Woo-Jong
Published: May 2024

Cesarean sections are commonly performed under spinal anesthesia, which can lead to hypotension, adversely affecting maternal and fetal outcomes. Hypotension following spinal anesthesia is generally defined as a blood pressure of 80–90% below the baseline value. Various strategies have been implemented to reduce the incidence of spinal anesthesia-induced hypotension. The administration of vasopressors is a crucial method for preventing and treating hypotension. In the past decade, phenylephrine, a primarily alpha-adrenergic agonist, has been the preferred vasopressor for cesarean sections. Recently, norepinephrine, a potent alpha-agonist with modest beta-agonist activity, has gained popularity owing to its advantages over phenylephrine. Vasopressors can be administered via a bolus or continuous infusion. Although administering boluses alone is simpler in a clinical setting, continuous prophylactic infusion initiated immediately after spinal anesthesia is more effective in reducing the incidence of hypotension. Tailoring the infusion dose based on the patient’s body weight and adjusting the rate in response to blood pressure changes, in addition to using a prophylactic or rescue bolus, helps reduce blood pressure variability during cesarean sections under spinal anesthesia until neonatal delivery.
COMPARISON OF PLOT ANALYTICAL METHODS FOR DETERMINING EXCESSIVE WATER PRODUCTION MECHANISMS IN OIL WELLS
Authors: Chasovskikh O.A. , Prokhorov E.I. , Motorova K.A.
Published: May 2024

Watering of production wells is an important factor leading to a decrease in production profitability and an increase in costs. There are several main mechanisms of excess water inflow. These are a leak in the production casing; a violation of contact between the production casing and the rock; a formation of a bottom water cone; a raising the WOC surface to the perforation interval; a breakthrough through a layer with high permeability. Mechanisms can complement each other, forming a complex integrated system. To identify them, there are three groups of diagnostic methods — geophysical research, hydrodynamic well testing and plot analytical studies. Each of these fundamentally different groups can be supplemented by field research. Specifically in this work, we considered the latter. The analysis is carried out using the example of wells in one of the deposits of an oil field of the Arkhangelsk region. In which the causes of unwanted water production have already been studied by other methods and can be considered known. The studied reservoir is massive, with carbonate hydrophobic rocks and the reserves of the entire field are predominantly concentrated in it (97 %); the oil field (in terms of reserves) is small. There are no injection wells, operation is carried out in a natural elastic water drive mode. In the article, in total, three plot analytical methods are analyzed, which are among the main ones and have different application algorithms. Both the physical principles of their application and their effectiveness in relation to specific oil field are considered. These are the methods of K. Chan; L.I. Merkulova and A.A. Ginzburg; R. Novotny. The first studies the dependence of the water-oil ratio and its derivative on time (WOR and WOR’(t)), is the most widely known and has a large number of modifications (however, here they are not considered in detail). The second is based on the study of the so-called «water-cut characteristics» (representing the dependence of the accumulated oil production vs accumulated liquid production during the water period of operation). It has more restrictions, but is also more comprehensive. The third is based on a comparison of the permeability properties of reservoirs that change during operation.
INFLUENCE OF ELECTROMAGNETIC TREATMENT ON HYDRAULIC CHARACTERISTICS OF HOT PIPELINES DURING NEWTONIAN AND NON-NEWTONIAN PETROLEUM SYSTEMS TRANSPORTATION

Published: May 2024

This work examines the influence of radio-frequency (RF) electromagnetic (EM) influence on the hydraulic characteristics of hot pipelines for the transport of petroleum Newtonian and non-Newtonian systems.Newtonian and non-Newtonian petroleum and their rheological properties before and after RF EM exposure, as well as the hydraulic characteristics of hot petroleum pipelines for pumping selected petroleum, were selected as objects of study.As a result: a methodology for petroleum processing has been developed that corresponds to industrial practice in the operation of petroleum pipelines; empirical dependences of petroleum viscosity on temperature were obtained in the form of piecewise exponential functions. The influence of RF EM exposure on the thixotropic properties of petroleum and the values of ultimate shear stresses was assessed. A decrease or complete disappearance of hysteresis loops after RF EM exposure to petroleum and a decrease in the maximum shear stress for non-Newtonian petroleum were revealed.By using the software developed by the authors, «Hydraulic calculation of isothermal and non-isothermal petroleum pipelines (GRINT)», the processes of pipeline transport of petroleum treated with EM fields were modeled, taking into account the obtained empirical dependencies. An assessment of the influence of RF EM exposure on the hydraulic characteristics of «hot» pipelines was carried out. It has been established that after RF EM exposure to petroleum, the zone of stable operation of a «hot» petroleum pipeline increases and the required pressure for pumping the same volume of petroleum decreases.
STUDYING THE INFLUENCE OF NEW COMBINED INHIBITORS ON THE PROCESSES OF CORROSION AND SALT DEPOSITION IN OIL-FIELD EQUIPMENT
Authors: Mamedov K.A.
Published: May 2024

Aggressive salts contained in formation waters accelerate the processes of corrosion and salt deposition in oilfield equipment, which leads to unforeseen accidents, contamination of soil and groundwater with harmful substances, as a result of which the ecological balance of the environment is disrupted. Corrosion and scaling that occur during oil production create difficulties during the operation of wells, and, consequently, increase the cost of produced oil.This article covers the results of studies concerning two compositions developed from technical phosphatide - an emulsion obtained by hydration of vegetable oils, as well as sodium hexametaphosphate, ammophos and polypropylene glycol bottoms. When vegetable oils are treated with water and steam (hydration process), the phospholipids contained in the oils combine with water and are released in the form of precipitates called phosphatide emulsions. Such emulsions consist of 45–75 % water, and the rest is phospholipids in the vegetable oil sediment.Technical phosphatides are a group of esters that contain a phosphoric acid residue associated with an amino alcohol. They are natural surfactants and are non-toxic.Preliminary studies have shown that each of the chemical compounds included in the developed reagents has certain inhibitory properties, but when formulated, these compounds provide a synergistic effect.Based on the results of laboratory studies, it was found that at an optimal concentration of reagents of 200 mg/l, the developed compositions provide protection of equipment from corrosion destruction by 94–95 %, and from scaling by 87–88 %. The developed mixed-type inhibitors at optimal concentrations equally effectively inhibit both cathodic and anodic processes on the electrode.The use of these inhibitors leads to the prevention of steel corrosion in the two-phase oil-electrolyte system, as well as to a significant reduction in the rate of scaling.The proposed new compositions can be used in oil wells and in-field transport systems, as well as in reservoir pressure maintenance systems to protect against corrosion and scale deposits.Field tests of the corrosion inhibitor were carried out in deep pumping wells at the Bibieybatneft oil and gas production department. Tests have shown that as a result of using the inhibitor, the protective effect at a concentration of 200 mg/l was 89–90 %, and the effect of salt deposition was 70 %.
INFLUENCE OF THE TYPE OF MATERIAL OF DELAYED COKING REACTORS ON DAMAGE DURING OPERATION
Authors: Badin Yu.A.
Published: May 2024

The problem of increased damage to delayed coking reactors (DCRs) or coke drums in domestic and foreign oil refining practice is still relevant. To date, significant progress has been made abroad in understanding the mechanisms of damage to DCR; numerous measures have been formulated, tested for widespread use, and have been used for a considerable time to improve the resistance to operational damage of DCRs. There is an urgent need to adapt and use positive foreign experience in the domestic practice of designing and operating DCRs, which will allow for a significant reduction in their damageability. Among the measures to increase the resistance to operational damage of DCRs, the most important place is occupied by the determination of technical requirements for their material design. The article compares the technical requirements for the material design of the DCR in domestic and foreign design practice, and analyzes the operating experience of the DCR with different material designs. Data on recorded damage obtained during the operation of DCRs is presented, data on the chemical composition and mechanical properties of the materials used in the manufacture of DCRs, the results of technical diagnostics of DCRs are provided with illustrative materials of damage zones of DCRs. A comparison is made in the level of resistance to operational damage of DCRs with different material designs. The results of previously performed studies on mathematical modeling of the stress-strain state of the elements of DCRs are used, with verification of strength conditions. Recommendations for the material implementation of DCRs are provided. Proposals for changes in the technical requirements for the material design of the DCRs are formulated in terms of mechanical characteristics (yield strength) in the delivered state.
USE OF ETHOXYLATED ALCOHOLS WITH ANIONIC SURFACTANTS FOR ENHANCED RECOVERY
Authors: Gafarov Sh.A. , Chernov M.V. , Ivanov A.B. , Faizov R.A.
Published: May 2024

The article is devoted to the development of surfactant compositions, including a number of known anionic surfactants, in formulations with new types of nonionic surfactants - fatty alcohols with an increased degree of ethoxylation. The solubilizing properties of new types of fatty ethoxylated alcohols have been exploited during formulation development. A conductometric method was used to control the assembly of the formulations. After evaluating the stability of the resulting compositions, physicochemical properties were evaluated, including thermal stability and corrosiveness. The freezing point of the compositions was evaluated at temperatures down to minus 40 °C. The search for stable compositions was carried out for aggressive application conditions: at 90 ° C for models of mineralized formation waters having a total amount of dissolved salts in the range of 100-300 g/l. Ranges including critical concentrations of formulations at which colloidal structures are stable and exhibit maximum surface activity were evaluated. When determining the interfacial tension at the surfactant-hydrocarbon liquid solution boundary, a number of developed compositions showed ultra-low interfacial tension (less than 0.01 mN/m). Biodegradability was evaluated for compositions showing the best properties. According to the results of the assessment, biodegradability was more than 98 %, which reduces environmental risks. The results obtained by the authors show that a number of compositions collected by conductometric method are stable under aggressive conditions and can be used in the field of chemical methods for increasing oil recovery. The resulting compositions were adapted to reduce human factors in subsequent applications. The results reflect the potential of these approaches in adapting and selecting surfactant compositions for chemical waterflooding to enhance oil recovery. The development of technologies for the ethoxylation of higher fatty alcohols allows the manufacturability of processes for the production, collection and treatment of oil and gas. The development of practices for the use of new chemical technologies will expand the capabilities of subsoil users and reduce the risks associated with the use of large-scale chemical products.

Published: May 2024

A persistent negative situation in the sphere of corruption in Russia, as well as the enforcement of a new National Anti-corruption Plan for 2021-2024 approved by the Decree of the President of the Russian Federation of August 16, 2021 № 478, the search for new forms and methods of preventing this criminal social phenomenon and of counteracting it gain a special urgency. Experience shows that criminal law measures are not sufficient for counteracting corruption. Due to this, the role of criminology seems especially vital. A comprehensive study of the criminal’s personality will help to improve the effectiveness of preventive work for the category of people under consideration. The goal of the work is to research specific socio-demographic, moral-psychological, role and criminal law characteristics of the personality of a bribetaker in Russia today. The research is based on the analysis of Russian and foreign publications in journals of law and sociology. The empirical part consists in studying the decisions of the courts of general jurisdiction of different subjects of the Russian Federation (from 2018 to 2023) and official statistical information on criminal prosecution under Art. 290 of the Criminal Code of the Russian Federation. Besides, the author carried out a content analysis of electronic mass media on high-profile cases of bribery involving officials at different levels. It was found that, at the present time, a bribetaker in Russia is male (with a growing share of female bribetakers), aged 30-49, a Russian citizen with a higher education, married with underage children, employed by law enforcement or state and municipal bodies. He is described favorably as a responsible, sociable and competent person both at work and in personal life. Key individual psychological features include emotional stability, ability to control and manipulate people, ability to build necessary connections, denial of moral and criminal norms, avarice, tolerance to corruption, thirst for power and a desire to prove himself through illegal actions.

Authors: Qiu Xueping , Pecheritsa Vladimir , Lo Xuan
Published: May 2024

The relevance is due to the fact that the main rea¬sons and prerequisites for the expansion of military activity of the Arctic countries are caused by the aggravation of the international situation in the world, the emergence of a new architecture of international relations. It is emphasised that the increasing role of the Russian Federation in the global energy and food markets, as well as in the global maritime logistics, blocks the United States and its NATO allies, forcing them to pursue an aggressive course and militarize the Arctic. Russia is forced to retaliate by strengthening its defence in this region. The article is aimed at the author's assessment of the processes of militarisation of the Arctic, the authors use the following research methods: structural-functional logistic, historical-comparative. The task of the research is to study the strengthening of the role of the Arctic in modern conditions. The article uses elements of expertise. Strengthening the Arctic security of the Russian Federation hopes for a sensible approach and independent from the U.S. Arctic policy of small states members of the Arctic Council, such as Iceland, Denmark, Norway, Sweden, which Washington tries to “twist arms” and forces to strengthen military presence in the region. Moscow also counts on the support of such friendly countries as India and China to develop the Arctic and strengthen regional security in this emerging region. A good dialogue and joint practical activities in the Arctic have already been built with China. Its economy, economic power, and growing political weight as a nuclear power and as a permanent member of the UN Security Council are indisputable. China is increasingly becoming a global superpower capable of really confronting the United States.

Published: May 2024

The article presents multi-stage parametric programming models, the characteristics of which depend on time and seasonality. The first model took into account the impact on the yield of agricultural crops of predecessors. In the second model, related to the distribution of sales of products by seasons, at the first stage, a point and interval forecast of the task parameters is carried out, at the second stage, optimal coefficients are determined that characterize the volume of sales of crop products depending on the season. Then, based on the obtained forecasts and optimal coefficients, the parametric programming problem is solved. The described tasks are implemented on real objects of the Irkutsk region. Logistic and asymptotic dependences are used to predict crop yields, and the price trend is a seasonal model. It should be noted that the presented models can be refined with the help of expert assessments, which will improve the adequacy of planning the activities of agricultural producers.

The place of children’s literature in the literary system
Authors:   Universidad de Valencia, Mínguez-López Xavier
Published: May 2024

The status of children’s literature within the literary system has generated all kind of discussions. We can find those who considered there was no such a thing, and it should rather be integrated to literature in general. On the oppositeside, there were those who called for its own space even from a critical point of view. In this debate it is necessary to resort to wider theories in order to realize which relationship children’s literature has to the general literary system. Undoubtedly, the theories that better help define such a relationship are Pierre Bourdieu’s theory of literary field, and Itamar Even-Zohar’s theory of polysystems. Although generally named in children’s literature studies to legitimize their change of status from the 1970’s, they are usually not developed from this paradigm. The author’s intention is to see how these theories helpbetter understand the phenomenon of children’s literature and its relation to general literature. From this point of view, the most important contributions are the removal of formal patterns in the definition and introduction of social parameters, such as production, reception, consumption, etc., which definitely influence its configuration.

Introduction: cannabinoids have a wide range of biological effects and are currently used for therapeutic purposes in modern medicine. The objective was to determine the effects and clinical application of cannabinoids as a therapeutic alternative for periodontal disease. Methods: we conducted a systematic review following the Cochrane manual for systematic reviews' recommendations to address the following inquiries: 1) What is the impact of non-surgical therapy with cannabidiol compared to conventional non-surgical therapy on the level of insertion in patients with periodontal disease? 2) What are the potential biological and microbiological effects of cannabinoids in the treatment of periodontal disease? The primary outcome was changes in the periodontal attachment level (CAL) and secondary outcomes included changes in probing depth (PD), changes in bleeding on probing (BoP), report of adverse effects and microbiological and biological effects. Results: out of 59 potential studies, 26 were excluded in the initial screening, and 33 full-text studies underwent further review. Among these, 13 were excluded for not meeting the selection criteria, resulting in 20 studies included in the qualitative synthesis. Notably, only one highly biased human clinical study was identified. In vitro and animal studies demonstrated that cannabinoids possess bactericidal properties, anti-inflammatory potential, and modulating activity on periodontal bone resorption. Conclusions: the available scientific evidence is scarce to recommend the use of cannabis derivatives for the treatment of periodontal disease. Despite promising findings in preclinical studies indicating therapeutic potential, further investigation is required to assess its application in human subjects.

Sound Terminology in Sonification
Authors: Ziemer Tim
Published: May 2024

Sonification research is intrinsically interdisciplinary. Consequently, a proper documentation of and interdisciplinary discourse about a sonification is often hindered by terminology discrepancies between involved disciplines, i.e., the lack of a common sound terminology in sonification research. Without a common ground, a researcher from one discipline may have trouble understanding the implementation and imagining the resulting sound perception of a sonification, if the sonification is described by a researcher from another discipline. To find a common ground, the author consulted literature on interdisciplinary research and discourse, identified problems that occur in sonification, and applied the recommended solutions. As a result, the author recommends considering three aspects of sonification individually, namely 1) Sound Design Concept, 2) Objective, and 3) Evaluation, clarifying which discipline is involved in which aspect and sticking to this discipline’s terminology. As two requirements of sonifications are that they are a) reproducible and b) interpretable, the author recommends documenting and discussing every sonification design once using audio engineering terminology and once using psychoacoustic terminology. The appendixes provide comprehensive lists of sound terms from both disciplines, together with relevant literature and a clarification of often misunderstood and misused terms.
Speech, Nonspeech Audio, and Visual Interruptions of a Tracking Task: A Replication and Extension of Nees and Sampsell (2021)
Authors: Nees Michael A. , Liu Claire , Bogan Krista
Published: May 2024

Interruptions from technology—such as alerts from mobile communication devices—are a pervasive aspect of modern life. Interruptions can be detrimental to performance of the ongoing, interrupted task. Designers often can choose whether interruptions are delivered as visual or auditory alerts. Contradictory theories have emerged regarding whether auditory or visual alerts are more harmful to performance of ongoing visual tasks. Multiple Resources Theory predicts better overall performance with auditory alerts, but Auditory Preemption Theory predicts better overall performance with visual alerts. Nees and Sampsell previously found that multitasking was superior with nonspeech auditory alerts as compared to visual alerts. In the current experiment, their methods were replicated and extended to include a speech auditory alerts condition. Performance of the ongoing tracking task was worse with interruption from visual alerts, and perceived workload also was highest in this condition. Reaction time to alerts was fastest with visual alerts. There also was converging evidence to suggest that performance with speech alerts was superior to performance with nonspeech tonal alerts. The current experiment replicated the results of Nees and Sampsell and extended their findings to speech alert sounds. Like in their study, the pattern of findings here support Multiple Resources Theory over Auditory Preemption Theory.
The Features of the Organization and Perception of Teamwork by Students in Distance Learning
Authors: Atrushkevich E.B.
Published: May 2024

The article explores the features of organizing teamwork among students in the context of distance learning. The research involves an analysis of the challenges faced by both students and teachers when working in teams. An ascertaining experiment is presented, during which the experimental group received detailed instructions on organizing teamwork, which led to improved learning outcomes compared to the control group. Additionally, a study was conducted to examine students' perception of teamwork in the "Digital Forest Pedagogy" distance learning course. A total of 56 second-year students from the Higher School of Technology and Energy of SPbSUITD participated in the survey. The analysis revealed that students perceive teamwork as more complex compared to working in pairs, their assessment is influenced by prior experience. Issues related to responsibility and self-discipline, coordination and collaboration, as well as communication and feedback, were identified as the most problematic aspects.
The Use of Board Games and Digital Games Preschoolers: Results of a Survey of Russian Parents

Published: May 2024

The article presents the results of an empirical study conducted within “The Influence of Digital Activity on the Development of Cognitive Functions in Preschool Age” project. In order to compare the data on the use of board games and digital games, a special “Contemporary Children: Digital Games vs. Board Games” questionnaire was developed (O.V. Salomatova, Yu.A. Tokarchuk, 2023), intended for the parents of preschoolers. The survey was conducted from March to September 2023 and involved parents of children aged 3 to 7 years old (N=556). It was shown that parents consider board games to be a more preferable pastime for children than digital games. According to the survey, board games in most cases involve the presence of a gaming partner, while digital games are more often an individual activity. In comparison with board games, parents more frequently use digital applications as a means of monitoring their child's behavior or as a method of reward. At the same time, according to the survey, parents less often actively participate in the process of digital gaming, allowing children to play independently or under their supervision. Board games more frequently involve parents in the gaming process.
Patient’s Privacy and Relatives’ Rights in Genetic Research
Authors: Moskovkina E. K.
Published: May 2024

The article discusses the collision of patient's right to confidentiality and their relatives interests to know a risk to the health earlier and to increase chance to receive therapy promptly. The author makes an ethical and legal analysis of the existing provisions governing the issue, and attempts to find practical solutions to the question of the doctor-patient relationship.

The approach that privacy can be limited according to the decision of the patient is the most doubtless according to legislation of considered countries. Doctor’s role is to assist to share patients’ genetic risks with concerned relatives and explains how it effects the health and, several tools for this are offered (e.x. letter about genetic risks with recommendations, opportunity to invite relative for consultation).

So, privacy is not absolute right and can be limited, but in what cases it is ethical? Legislation orders doctor to save patients’ rights. At the same time professional duty of physician to help people in a broad sense.

As a result, and due to burden of knowledge doctors are have to overcome the serious moral dilemma and find the compromise – how to inform patients relatives about risks and even prevent diseases and not to undermine trust of the patient. The legislation of most of the countries does not answer this question, recognizing the right to confidentiality not as an absolute right, but as a prevailing right in comparison with the relatives’ interests. At the same time, the problem is more detailed in “soft law” acts and more progressive approaches are proposed – to consider confidentiality on the family level (not individual) in sphere of genetics. Moving such approaches from soft law acts into the field of legislation will remove part of the decision-making burden from doctors.
