Cosmic-ray induced diffusion in interstellar ices

Cosmic rays are able to heat interstellar dust grains. This may enhance molecule mobility in icy mantles that have accumulated on the grains in dark cloud cores. A three-phase astrochemical model was used to investigate the molecule mobility in interstellar ices. Specifically, diffusion through pores in ice between the subsurface mantle and outer surface, assisted by whole-grain heating, was considered. It was found that the pores can serve as an efficient transport route for light species. The diffusion of chemical radicals from the mantle to the outer surface are most effective. These species accumulate in the mantle because of photodissociation by the cosmic-ray induced photons. The faster diffusion of hydrogen within the warm ice enhances the hydrogenation of radicals on pore surfaces. The overall result of the whole grain heating-induced radial diffusion in ice are higher abundances of the ice species whose synthesis involve light radicals. Examples of stable species synthesized this way include the complex organic molecules, OCS, H2O2 and cyanoplyynes

EMPIRICAL RESEARCH OF PSYCHOLOGICAL WELL – BEING OF YOUNG PEOPLE STUDYING AT REZEKNE ACADEMY OF TECHNOLOGY

This scientific article reflects the results of research on the psychological well-being of students at the Rezekne Academy of Technologies. The need for such research is justified by recent research in various countries, which shows that the prevalence and severity of mental problems among students is increasing. Overall, these studies indicate that students are increasingly experiencing symptoms of increased anxiety and stress, as well as depression. Thus, the deterioration of students' psychological well-being is a major challenge in today's higher education institutions.The aim of the empirical research: to study the content and peculiarities of the psychological well-being of students in relation to certain demographic and social factors.The analysis of scientific literature and empirical results were used as basic methods in the development of the article

STRESSORS OF THE STUDY PROCESS, THEIR EMPIRICAL RESEARCH AT RĒZEKNE ACADEMY OF TECHNOLOGIES

This scientific article presents a theoretical review of stress factors of young students and the results of empirical research of these factors at the Rezekne Academy of Technologies. The need for such research is justified by International studies (n=540 000), in which was found that the study process causes high level of stress in 37% of students. The results of other studies in different countries also show that the prevalence and severity of mental problems among students is increasing. Overall, these studies indicate that students are increasingly experiencing symptoms of increased anxiety and stress, as well as depression. Thus, increase in student stress levels and related deterioration of students' psychological well-being is a major challenge in today's higher education institutions. Taking into account the mentioned findings, the aim of this article is to identify the most common stress factors in the study process at the Rezekne Academy of Technologies. The analysis of scientific literature and empirical results were used as basic methods in the development of the article.

THE LEVEL OF SUBJECTIVE WELL-BEING (FEELING OF HAPPINESS) OF RTA STUDENTS AND ITS INFLUENCING FACTORS

This scientific article analyzes the level of subjective well-being of students of Rēzekne Academy of Technology (RTA) and the main factors affecting this phenomenon. The need for such studies is justified by the latest studies in various countries, which show that nowadays the prevalence and severity of mental problems among young people and early adulthood is increasing. Taken together, these studies show that students are increasingly experiencing symptoms of increased anxiety and stress, as well as depression. Thus, the deterioration of the subjective well-being of young students is a big challenge in modern universities. The purpose of the empirical study: to investigate the level of subjective well-being of students in relation to certain demographics, as well as to determine the factors that significantly influence this phenomenon in the student environment. The analysis of scientific literature and empirical results is used as a basic method in the development of the article

PECULIARITIES OF PSYCHOLOGICAL WELL – BEING YOUNG PEOPLE OF REZEKNE COMPREHENSIVE SCHOOLS

The problem of psychological well-being is particularly acute in the age group of young people, because during this time a person's identity is formed and the next profession is chosen. High psychological well-being implies the sense of purpose of life, optimism, the ability to establish positive attitudes with others, which creates preconditions for positive personality development. For this reason, young people from comprehensive schools were selected for the study.The significance of the research is justified by the fact that similar studies on psychological well-being in the youth age were not carried out in Latgale region.The aim of the study was to investigate the peculiarities of psychological well-being of young people in Rezekne comprehensive schools
