Authors: Soha Alena , Ņesterenko Renata , Āziņa Inga , Rozentāle Baiba , Eglīte Jeļena 
Published: March 2024

Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has led to a global pandemic with serious implications and open questions for all areas of medicine, including immunocompromised patients. In Latvia, as of the end of 2022, 229 new cases of HIV were registered, reflecting an incidence rate of 12.2 per 100,000 people. Despite the fact that immunocompromised patients are at risk of poor outcomes of COVID-19, there is currently no evidence that clinical manifestations of COVID-19 in people living with HIV (PLWH) differ from those in the general population, provided these patients have well-controlled immune status (CD4+ count > 200 and undetectable viral load). We report two cases of COVID-19, specifically the Delta variant, in male patients with well-controlled HIV infection who had received three vaccine doses against COVID 19. Both patients fully recovered within one week without complications, requiring no specific treatment. Considering the current published data and our observations, it can be assumed that the course of COVID-19 in vaccinated well-controlled HIV patients does not differ from the typical clinical manifestations of COVID-19 in the general population. It is necessary to decrease vaccine hesitancy among PLWH, as COVID-19 vaccination is a crucial measure to safeguard this segment of the population against poor outcomes of COVID-19 such as hospitalisation, the risk of long-term health problems, severe disease, and death).

Abstract
Future Algerian agricultural projects are oriented to the Sahara. Knowing that generally electrical energy is supplied largely by Generator Diesel (DGs). Due to the difficulty and lack of land roads for these desert areas, which creates fluctuations in the fuel supply process for farmers. In order to find a solution to mitigate this fluctuation requires the use of modern technology such as the hybridization of local renewable energy such as solar energy. Our system consists of the integration of a photogenerator (PVG) with a DG to feed a synchronous motor coupled to a central water pump controlled by means of transformers. This work presents an intelligent approach for improving and optimizing the control performance of a system using the Fuzzy Logic Control (FLC) based maximum power point tracking (MPPT) method. In this article, we will analyze a contribution to the use of a hybrid energy system (PVG-DG) according to a management strategy whose purpose is to reduce energy costs and reduce the emission of greenhouse gases (CO2). Our simulation results presented at the end of the article have demonstrated the efficiency and flexibility of the Matlab simulated techniques system based on the actual geographic information of the study area to validate the performance of the proposed system. Which can be used in other practical studies in the future.

Рurpose of the research: to evaluate an effectiveness of use of two different construction types of tourniquets (belt type/elastic band/bandage and tourniquet) for extremities arterial haemostasis on volunteers. Research problem: to complete comparative research of the tourniquets and elastic bandages in the research on volunteers; to evaluate the effectiveness of tourniquets for arterial haemorrhage on extremities; to compare an effect of use of tourniquets and elastic bandages; to evaluate the possibility of the treatment of prolonged external haemorrhage by an ambulance. Materials and methods: the research has been held on 20 volunteers. The following items were the research objects: tourniquet ЖК‑01; ЖК‑02 designed by Medplant and haemostatic elastic bandage with the loop fastening “Alfa”. The research included 2 stages: use of the items on summertime and wintertime military uniform of participating volunteers. The items were used on upper and lower extremities as a self‑help and as mutual assistance. Studied parameters: time of application, effectiveness of haemostasis, ergonomic characteristics, the level of discomfort in the place of application of the researched items. Results: the research results demonstrate that both items‑elastic bandage and the tourniquets effectively stop external arterial haemorrhage. Tourniquets ЖК‑01 and ЖК‑02 and elastic bandage Alfa have been found to decrease their effectiveness when applied to the wintertime military uniform, which is explained by the presence of extra layers of fabric. Tourniquets ЖК‑01 and 02 allow to level down the discomfort in the place of application in comparison with the bandage Alfa. The benefit of usage of tourniquet type of bandage is that controlled compression may be applied that enables to control the haemorrhage during evacuation and in the hospital. Conclusion: tourniquets ЖК‑01 and ЖК‑02 by Medplant are promising tools to be used in injured and wounded patients by ambulance services.
Study of Two-Fluid Effects in Weakly Ionized Plasma Under Electromagnetic Fields
Authors: Hou Yuhang , Feng Yongliang , Zheng Xiaojing 
Published: March 2024

The multifluid effects caused by the relative motion and interaction between plasma components have a significant effect on electromagnetohydrodynamic wave propagation and the related mass and energy transport of flows. In this work, the charged particle (ion and electron)–neutral two-fluid model is analyzed and employed to study the two-fluid effects (e.g., velocity drift and thermodynamic nonequilibrium between plasma components) of the weakly ionized plasma flows under the electromagnetic fields. In a hypersonic [Formula: see text] crossed-field configuration acceleration problem, the increased electromagnetic field strength significantly enhances the two-fluid effects. When the load factor equals 3, which measures the strength of the electrode voltage and induced electromotive force, the relative velocity difference between the charged particles and neutrals can reach 28%. The influences of two-fluid effects appreciably increase with the Mach number and Knudsen number but decrease with the degree of ionization. This suggests that, as the vehicle speed and altitude increase, the two-fluid effects become more significant.

Published: March 2024

В современной нефтегазовой индустрии актуализируется необходимость подготовки кадров с комплексным набором профессиональных и трансдисциплинарных компетенций. Проблематика оценки эффективности образовательных программ в вузах, ориентированных на подготовку специалистов для нефтегазовой отрасли, приобретает особую релевантность. Настоящая статья фокусируется на разработке и анализе многокритериальных методов оценки компетенций студентов в нефтегазовых вузах Российской Федерации. Рассматривается применение комбинированных методологических подходов, включая машинное обучение, методы многомерной статистики и экономико-математическое моделирование. Осуществлен критический обзор существующих практик, выделены их недостатки и предложены новаторские решения. Эмпирическая база исследования представлена данными из 37 нефтегазовых вузов России, собранными в период с 2018 по 2021 годы. Используя методологию многокритериального анализа, авторы предлагают модель, которая учитывает 12 ключевых компетенций и 7 контекстуальных переменных. Одним из важных аспектов, требующих аналитического осмысления, является выбор метрик для оценки компетенций. В различных вузах применяются инструменты, сосредоточенные на измерении одного или нескольких аспектов (например, знаний, навыков, способностей). Напротив, в данном исследовании предложена интегрированная методология, базирующаяся на комбинировании методов многомерной статистики и алгоритмов машинного обучения.
In the modern oil and gas industry, the need for training personnel with a comprehensive set of professional and transdisciplinary competencies is being actualized. The problems of evaluating the effectiveness of educational programs at universities focused on training specialists for the oil and gas industry are becoming particularly relevant. This article focuses on the development and analysis of multi-criteria methods for assessing students' competencies in oil and gas universities of the Russian Federation. The application of combined methodological approaches, including machine learning, methods of multidimensional statistics and economic and mathematical modeling, is considered. A critical review of existing practices was carried out, their shortcomings were highlighted and innovative solutions were proposed. The empirical base of the study is represented by data from 37 oil and gas universities in Russia, collected in the period from 2018 to 2021. Using the methodology of multi-criteria analysis, the authors propose a model that takes into account 12 key competencies and 7 contextual variables. One of the important aspects that require analytical thinking is the choice of metrics for assessing competencies. Various universities use tools focused on measuring one or more aspects (for example, knowledge, skills, abilities). On the contrary, this study proposes an integrated methodology based on a combination of methods of multidimensional statistics and machine learning algorithms.

Published: March 2024

В статье рассматриваются языковая ситуация в современной Индии, после обретения независимости. Один из вопросов заключается в том, приведет ли дальнейшее сохранение английского языка в качестве официального в стране, особенно в государственном администрировании, в бизнесе, в сфере образования и науки к ослаблению положения хинди и других индийских языков, создает ли это угрозу национальной идентичности Индии или наоборот способствует еще большему сплочению индийцев в единую нацию на базе единого и нейтрального для всех языка в стране претендующей на статус одной из мировых держав. Автором проанализирован целый ряд аспектов, оказывающих влияние на статус и функционирование языка в современных условиях. На основе представленных здесь фактов автор обосновывает возможность, неизбежность и целесообразность сохранения за английским языком своих позиций и даже их укреплений с учетом статуса английского в мировых масштабах. Поскольку английский является основным языком в международных отношениях, науке, образовании, в национальном администрировании и в национальных компаниях, количество так называемых индо-англичан будет продолжать увеличиваться. Но, с другой стороны, у Индии увеличиваются шансы стать единой страной, при множестве языков и своих национальных героях и кумирах в каждом штатов настоящий момент трудно говорить о по-настоящему единой стране.
The article examines the linguistic situation in modern India after independence. One of the questions is whether the continued preservation of English as the official language in the country, especially in public administration, business, education and science, will weaken the position of Hindi and other Indian languages, whether this poses a threat to India's national identity or, conversely, contributes to even greater cohesion of Indians into a single nation based on a single and neutral language for all in a country claiming the status of one of the world powers. The author analyzes a number of aspects that influence the status and functioning of the language in modern conditions. Based on the facts presented here, the author substantiates the possibility, inevitability and expediency of preserving the English language's positions and even strengthening them, taking into account the status of English on a global scale. Since English is the main language in international relations, science, education, national administration and national companies, the number of so-called Indo-English will continue to increase. But, on the other hand, India's chances of becoming a single country are increasing, with many languages and its national heroes and idols in each state, it is currently difficult to talk about a truly united country.
One unconditionally stable CABARET class scheme for shallow water equations
Authors: Соловьев А.В. , Асфандияров Д.Г. 
Published: March 2024

В работе рассматривается новый подход к построению неявных безусловно устойчивых схем в рамках балансно-характеристической методики КАБАРЕ применительно к системе уравнений мелкой воды. Метод основан на идее инверсии координатных осей в явной схеме КАБАРЕ для преодоления ограничения на шаг по времени. Система уравнений является нелинейной, так как в уравнения включены минмаксные операции лимитирования на основе принципа максимума для локальных инвариантов Римана. Такое лимитирование существенно улучшает дисперсионные свойства схемы. Нелинейная система уравнений решается методом бегущего счета. В работе представлен вывод схемы для числа Куранта–Фридрихса–Леви CFL ≤ 1 и CFL > 1. Приведены тестовые расчеты на примерах простейшего уравнения переноса и одномерных задачах мелкой воды для дозвукового случая. Сделаны выводы о влиянии нелинейной коррекции потоков на решение для данной схемы.
The paper considers a new approach to the construction of implicit unconditionally stable schemes within the framework of the CABARET balance-characteristic technique in relation to the system of shallow water equations. The method is based on the idea of inverting coordinate axes in the CABARET scheme to overcome the time step limitation. The system of equations is nonlinear, since the equations include minmax limiting operations based on the maximum principle for local Riemann invariants. This limitation significantly improves the dispersion properties of the numerical scheme. The nonlinear system of equations is solved using the marching order method. The paper presents the derivation of the numerical scheme for the Courant–Friedrichs–Lewy number CFL ≤ 1 and CFL > 1. Test calculations are presented on the simplest transport equation and one-dimensional shallow water problems for the subsonic case. Conclusions are drawn about the influence of nonlinear flux correction on the solution.
