Purpose of the study. Assess the knowledge of medical professionals providing assistance to victims with traumatic injuries to the facial skull, obtained in the context of road accidents. Materials and methods. For the study, a special questionnaire was developed, including 11 questions. The annotation involved 100 medical professionals working in emergency medical teams. Of these, 50 (50%) people with higher education, the corresponding certificate and holding the positions of doctors providing medical care in the city, another 50 (50%) people who had secondary medical education and worked as a paramedic providing medical care in rural conditions. Results. As a result of the study, the following results were obtained: most specialists working in emergency medical teams have sufficient knowledge of medical care for injuries to the facial skull, at the same time, most specialists do not have a specialized education in dentistry, which does not in all cases help to provide correct and competent care for such sufficiently specific injuries. This can lead to the choice of wrong tactics, which ultimately affects the treatment results of such victims. In this regard, pretexts to develop and introduce into practice specialized courses on the improvement of specialists working in emergency medical teams, which would be conducted by specialists in maxillofacial surgery, as well as disaster medicine. In our opinion, this will reduce the number of errors arising in the provision of medical care to such victims.
Fundamental Experiment and Numerical Simulation of Ne/Xe Plasma Magnetohydrodynamic Electrical Power Generation
Authors: Ork Kimsor , Masuda Ryu , Okuno Yoshihiro 
Published: March 2024

We conducted experiments in a shock-tube facility to test magnetohydrodynamic (MHD) electrical power generation with Xe-seeded Ne plasma. The performance and plasma behavior of the experimental generator were examined using time-dependent [Formula: see text] two-dimensional numerical simulations. In the experiment, an enthalpy extraction ratio of about 5.0% was obtained using a disk-shaped MHD generator with radio frequency pre-ionization. The numerical simulations show that the enthalpy extraction ratio is improved by adding small amounts of Xe to Ne, but also that adding excessive amounts of Xe deteriorates the generator performance. When an appropriate inlet electron temperature is assumed in the simulations, 5900–6450 K (inlet ionization degree of [Formula: see text]) for a seed fraction (mole % of Xe) of 0.1%, 6050–6280 K [Formula: see text] for a seed fraction of 1.0%, and 5750–5950 K [Formula: see text] for a seed fraction of 5.0%, the plasma structure almost becomes similar to the nonuniform plasma structure observed in the experiment, as too does the enthalpy extraction ratio. The simulations suggest that achieving an inlet ionization degree above [Formula: see text] when using Ne/Xe with a seed fraction of 0.1–1.0% as the working gas should enable an enthalpy extraction ratio above 20%, which is expected to surpass that for pure Ar.

Abstract
SR gas field is located the North Oman Salt Basin. The BK and MQ are the two main formations targeted for gas production. In most cases, these formations are clastic deep tight gas reservoirs that contain considerable hydrocarbon reserves but exhibit ultralow permeability. The poor connectivity between the pores may significantly reduce the recovery for economic gas production. The formations were initially developed with fractured vertical wells targeting up to 10 different hydrocarbon units. A similar approach was carried forward in highly deviated to horizontal wells targeting the tighter zones. However, the intrinsic geomechanical, petrophysical, and lithological heterogeneities of these tight units impact not only the fracture geometry and conductivity distribution but also the drainage efficiency of the fractured zones. This phenomenon manifests as variations in the units, thereby influencing their contributions to the commingled production, with the areas of higher mobility dominating the total gas production in the current well architectures.
A horizontal well designed to obtain the production from the tight zone experienced some challenges on the drilling and completion. To address the operational challenges drilling, logging, and completing horizontal wells in this field, the acquisition of cased-hole logging data to characterize the mechanical anisotropy with a through-the-bit sonic dipole sonic tool deployed via a tractor has emerged as a compelling logging solution. The logging-while-drilling sonic tool has limitations in measuring shear anisotropy, and using the sonic through-the-bit tool in open hole poses for getting stuck. In this case study, sonic data were recorded through casing with the latest-generation slim dipole sonic tool via e-coil across the horizontal section, the first in the world for this type of deployment. The dipole shear sonic tool is capable of recording shear anisotropy, which is used to determine key elastic properties to assess the hydraulic requirements for optimizing the efficiency of fracturing BK units across the horizontal section.
We present fundamental considerations for acquiring and evaluating rock mechanical formation anisotropy using through-the-bit dipole shear sonic tool inside tubing by an e-coil. This work uses methods to assess the dynamic variations of in-situ stress by using shear anisotropy and to determine the key elastic properties to identify the hydraulic requirements for fracturing individual units or a combination of them along the horizontal section. Included in the study are considerations of logging requirements, conveyance method, and sonic data processing and results as well as petrophysical evaluation and other reservoir criteria.

В настоящее время неоспоримой актуальностью обладает вопрос оптимизации процессов преподавания иностранных языков в российских высших учебных заведениях. В рамках данного исследования предпринимается попытка анализа когнитивно-лингвистического подхода как возможного инструмента для совершенствования языкового образования. Целью является разработка методологического арсенала на основе когнитивной лингвистики, позволяющего повысить эффективность учебного процесса. Рассматривая статистические данные, взятые из 23 российских вузов с общим числом студентов 48,323, и проводя эксперименты на выборке из 821 студента, данная статья стремится выявить критерии оптимальности и перспективы применения когнитивно-лингвистических методик. В синтезе основных исследовательских выводов следует подчеркнуть, что когнитивно-лингвистическая парадигма в контексте оптимизации методик преподавания иностранных языков в российской высшей образовательной системе выступает как комплексно структурированный объект научного анализа. Согласно проведенным статистическим анализам, в которых применялись методы дисперсионного анализа и регрессионного моделирования, выявлено, что студенты, обучающиеся по когнитивно-лингвистической методике, в среднем показывают повышение уровня владения языком на 14,7% в сравнении со стандартными подходами. Следует отметить, что эти результаты статистически значимы (p <0.05).
Currently, the issue of optimizing the processes of teaching foreign languages in Russian higher educational institutions is of indisputable relevance. Within the framework of this study, an attempt is made to analyze the cognitive-linguistic approach as a possible tool for improving language education. The aim is to develop a methodological arsenal based on cognitive linguistics, which makes it possible to increase the effectiveness of the educational process. Considering statistical data taken from 23 Russian universities with a total number of 48,323 students, and conducting experiments on a sample of 821 students, this article seeks to identify optimality criteria and prospects for the use of cognitive-linguistic techniques. In the synthesis of the main research conclusions, it should be emphasized that the cognitive-linguistic paradigm in the context of optimizing the methods of teaching foreign languages in the Russian higher education system acts as a complex structured object of scientific analysis. According to the conducted statistical analyses, in which the methods of variance analysis and regression modeling were used, it was revealed that students studying cognitive-linguistic methods, on average, show an increase in the level of language proficiency by 14.7% compared with standard approaches. It should be noted that these results are statistically significant (p <0.05).

Published: March 2024

В статье предпринята попытка теоретического обоснования и экспериментальной верификации системы обратного наставничества как важного фактора формирования и раскрытия личностного потенциала субъектов образования. Обратное наставничество рассмотрено как инструмент формирования и развития человеческого капитала, который, в свою очередь, выступает базовым системным явлением метапредметного характера и становится все более актуальным в современной педагогической системе. Доказывается, что наставничество не зависит от возраста, привычное наставничество от педагога к ученику не всегда остаётся эффективным и, следовательно, возможен совершенно иной путь разработки и реализации системы наставничества. Предлагается модель организации обратного наставничества по финансовой грамотности в вузе. Обоснованы этапы наставнической деятельности в практике преподавания финансовой грамотности. Подробно описаны этапы и результаты педагогического эксперимента. Проведенное исследование и эксперимент показали, что основные цели были достигнуты, участники эксперимента (наставники) не просто сформировали предметные, метапредметные компетенции, но и задумались серьезно о ближайшей педагогической деятельности в данной системе. У большого количества слушателей-участников референтной группы появился высокий мотивационный уровень к освоению дисциплины; навыки разновозрастного взаимодействия по вопросам финансовой грамотности; осознание себя в качестве будущего педагога, которому предстоит общаться в новой реальности.
The article attempts to theoretically substantiate and experimentally verify the system of reverse mentoring as an important factor in the formation and disclosure of the personal potential of the subjects of education. Reverse mentoring is considered as a tool for the formation and development of human capital, which, in turn, acts as a basic systemic phenomenon of a meta-subject nature and is becoming increasingly relevant in the modern pedagogical system. It is proved that mentoring does not depend on age, the usual mentoring from teacher to student does not always remain effective and, therefore, a completely different way of developing and implementing a mentoring system is possible. The model of organization of reverse mentoring on financial literacy at the university is proposed. The stages of mentoring activity in the practice of teaching financial literacy are substantiated. The stages and results of the pedagogical experiment are described in detail. The conducted research and experiment showed that the main goals were achieved, the participants of the experiment (mentors) not only formed subject, meta-subject competencies, but also thought seriously about the nearest pedagogical activity in this system. A large number of students-participants of the reference group had a high motivational level to master the discipline; skills of multi-age interaction on financial literacy; self-awareness as a future teacher who will have to communicate in a new reality.
Features of using iterative successive substitutions methods for calculating phase equilibrium with a capillary jump
Authors: Райковский М.И. 
Published: March 2024

В статье представлены модификации методов последовательных приближений, которые используются для расчета фазового равновесия многокомпонентной термодинамической системы. В качестве примера рассмотрены два метода: метод последовательных приближений и метод квазиньютоновских последовательных приближений. Эти методы можно использовать для расчета равновесия между газовой и жидкой фазами со скачком капиллярного давления. Для проверки корректности методов результаты расчетов как фазового равновесия при заданных температуре и давлениях в фазах, так и фазовых диаграмм для различных температур сравнивались между собой. Получено малое расхождение в результатах при расчете фазового равновесия многокомпонентной смеси с учетом скачка капиллярного давления для летучей нефти.
This article presents modifications of Successive Substitution methods that are used to calculate the phase equilibrium of a multicomponent thermodynamic system. As an example, two methods are considered: the Successive Substitution method and the Quasi-Newton Successive Substitution method. These methods can be used to calculate the equilibrium between gas and liquid phases with a capillary pressure jump. To check the correctness of these methods, the results of calculations of both phase equilibrium at set temperature and pressures in the phases and phase diagrams for different temperatures were compared with each other. A low error in the results was obtained when calculating the phase equilibrium of a multicomponent mixture taking into account the capillary pressure jump for volatile oil.

Authors: Omodero C. O. 
Published: March 2024

The purpose of the study is to identify the impact of the tax system on investment in equity capital by analyzing the six types of taxes that affect the activities of firms. The data for the independent variables (tax classes in Nigeria) are obtained from the Federal Internal Revenue Service, while the data for the dependent variable (equity investment) are obtained from the Statistical Bulletin of the Central Bank of Nigeria. The necessary statistical methodologies are used to examine the impact of various tax classes on equity investment from 2011 to 2020. According to the research, capital gains tax and gas income tax have little effect on equity investment. The petroleum profit tax and corporate income tax have a considerable detrimental impact on equity investment. On the plus side, value added tax and education tax have a significant favorable impact on equity investment. These results are one-of-akind and precisely depict the genuine nature of the country’s tax system and its impact on investment. As a result, the research proposes a tax shift to lessen the tax burden on enterprises in order to stimulate equity investment, which will increase firms’ capital base for the purpose of business expansion and growth of the nation’s economic structure.
