Background. Dysosmia is a group of various disorders of the olfactory analyzer, manifested by an increase or decrease in the ability to perceive odors, up to a complete loss of olfactory sensitivity. Until recently, the problem of olfactory impairment was not as urgent as it became in 2019 and 2020, when the whole world faced a pandemic caused by the SARS-CoV-2 virus. Such interest of doctors and researchers in olfactory dysfunction can be explained by the very high incidence of dysosmia associated with COVID-19 – 60-80% of the total number of cases among the European population and 30% among the population of East Asia. Most often olfactory function recovers spontaneously on the background of treatment of the underlying disease, usually within one month, and does not require additional therapeutic measures. As early as on day 8-9, up to 70% of patients notice an improvement in their sense of smell, and 80-90% of patients regain their sense of smell after two weeks. However, about 10-15% of patients have to turn to specialists for lack of sense of smell for 20 days or more. The presence of anosmia for more than 15-20 days is probably due to possible damage to olfactory receptor cells themselves, which can take up to 2 months to recover.Conclusion. Since the olfactory function plays a large role in the life of every person, its loss can lead to discomfort, stress and limitation of various kinds of pleasures associated with the perception of smells, etc. In addition, the inability to distinguish odors can lead to poisoning with expired products or other harmful substances. Also, dysosmia associated with COVID-19 is of particular interest, since it has a specific neurosensory mechanism of occurrence associated with damage to the cells of the olfactory neuroepithelium. Therefore, it is necessary to develop an effective treatment plan for this complication of COVID-19 infection and conduct preventive education of the entire population.

Abstract The paper presents the results of gas dynamic calculation and strength analysis required to optimize the mathematical model of the body of the catalytic collector of a passenger car. Based on the obtained results of numerical modeling, the optimization of the case was performed. As a result of the gas-dynamic calculation, the optimal variant of the catalytic collector housing with the required uniformity of the exhaust gas flow in the input section of the catalyst (coefficient of unevenness (UI > 0.8)) was selected. According to the results of the strength analysis, stainless steel was selected to withstand emerging mechanical stresses at maximum temperatures up to 600 °C.

Today, the export of education in Russia continues to be an important state strategy of the Russian government, despite sanctions measures by European states and a decrease in the intensity of international cooperation with European countries. In 2022, the President of the Russian Federation set new goals for the export of education, according to which by 2030 the number of foreign students on higher education programs in Russian universities and scientific organizations should reach a minimum of 500 thousand people. Russia’s current foreign policy for the development and expansion of militarypolitical and trade-economic ties and common geopolitical realities have put on the agenda the development of new tools for international scientific and educational cooperation. The study aims to propose an effective strategy for the current state of the Russian education export from the perspective of a new geography and forms of international cooperation for increased activity on the global education market. The methodological basis of the study was formed by methods of comparative analysis of the domestic and foreign experience of higher education export, as well as systematization, generalization and interpretation of statistical information, posted on the websites of the Ministry of Science and Higher Education of the Russian Federation, leading Russian and foreign universities, authorities, and analytical agencies. The main result of the study is an analysis of the tools and mechanisms for expansion of the geography of the Russian education export and the promotion of the competitive brand of the Russian universities in conditions of isolation. The article shows that these tools allow to solve multifaceted tasks including the creation of a positive basis for political and economic interaction and training specialists in Russia and abroad to implement joint plans for the development of various areas of cooperation. The article contains the proposals for expanding the export of Russian education in view of new geopolitical realities. The CIS, Asia, Africa and Latin America are considered as the key partners.

Abstract In this article, we investigate the development and use of thermal memory elements based on thin-film aluminum devices on silicon wafer. To stabilize their operation and reduce the number of errors during the read/write process of thermal information in such devices, we propose an algorithm (referred to as the floating zero algorithm) for adjusting the temperature conditions of thermal memory cells. This algorithm controls the thermal memory cells on silicon under varying ambient temperature conditions. We tested the algorithm performance using an experimental thermal memory sample at room temperature. Additionally, we conducted a study on the degradation process of the sample under high electrothermal loading conditions. The results showed that the degradation process in the sample starts when a single current pulse of duration τ i ≥ 100 µs and amplitude density j i ≥ 8.5 × 1010 A/m2) flows through the device. We propose a criterion for determining the safe operation area γ of the device under investigation and experimentally determine its value γ = 6.0(VA√s).

This paper presents the results of a computational experiment on the natural vibrations of a homogeneous rigidly fixed plate after a temperature shock. Unlike in many well-known studies, in this work, the plate is not stationary at the moment of thermal shock. This formulation has wide practical applications. For example, as a result of the unfolding of solar panels, free vibrations are excited. The purpose of this work was to analyze the effect of temperature shock on the characteristics of the plate’s own vibrations. Specifying the parameters of natural vibrations and considering temperature shock make it possible to model the vibration process more adequately. The simulation parameters simulate the conditions of the space environment. Therefore, the results of this study can be applied to the study of thermal vibrations in solar panels and other large elastic elements of spacecraft.
