A comparative study of GitHub-hosted, self-hosted, and Kubernetes-based GitHub Runners for web applications GitHub Actions workflows

The purpose of this thesis was to determine which approach to hosting GitHub Actions software is more suitable for different requirements and use case scenarios. The focus was on examining the average time spent to execute CI/CD workflow, how much and how properly computing resources were utilised, as well as the cost to execute such workflow. The GitHub Actions tool was chosen as the CI/CD solution, as well as GitHub runners as compute instances running GitHub Actions software. In particular, GitHub-hosted, self-hosted, and Kubernetes-based runner performances in regard to time consumption, resource utilization, and cost were compared. The results indicate that every GitHub runner solution possesses some advantages and limitations. GitHub-hosted runners are convenient and simple to use but can be costly for large and frequent workflows. Self-hosted runners offer greater control over the environment and cost savings but require a high maintenance level. Kubernetes-based runners tend to be more complex to set up, offer greater scalability, and cost-effectiveness in the long run by optimizing the utilization of resources and reducing the need for manual intervention. Kubernetes-based runners are most effective in the long run for large projects, whereas GitHub-hosted and self-hosted runners remain suitable options for small projects with low infrastructure overhead

Preparing Students of the Institute of Physical Education and Sport to Use Distant Learning Technologies in the Course of Pandemic

This study reveals the importance of distance learning for professional students’ training in this innovative activity in regional institute of physical education. The urgency of research is based on the problem of insufficient readiness of physical education teachers and sports coaches in the Republic of Sakha (Yakutia) to implement distance learning. It is also based on the lack of widely used educational programs that are scientifically grounded, well tested in practice and that promote targeted training of physical education teachers to use DL technologies in the course of pandemic. The experiment involved bachelors’ and masters’ degree students in various specialties from the M.K. Ammosov North-Eastern Federal University (NEFU) and the Churapchinsky State Institute of Physical Education and Sport. All the students were majoring in Pedagogical Education and Physical Education. The leading method of research into the problem is the use of mathematical statistics to monitor the dynamics of the process development of training future physical education teachers and sports coaches to use DL technology. Main findings: The research results show that the use of new types of educational activities in the course of pandemic contributes to the effective contemporary professional training of Physical Education teachers and sports coaches.The practical implications of the research may be found in the analysis of future Physical Education teachers’ training to use DL in conditions of remote excess to the educative process of the discipline “Information Technologies in Physical Education and Sports” study. The content of the article will be useful for faculty members of institutions of higher education, institutions of additional education, and physical education teachers. The originality of this study is in providing the facts that the high proficiency and professional capacity of graduates of physical culture institutes, their ability and competence to adjust the accumulated knowledge and skills to new goals and objectives of education, regularly changing conditions of professional activity can be formed and developed through the effective use of DL technologies. adapted to the solution of occupational tasks

The Australian Vector of Mongolian Migration: Basic Parameters and Trends

Goals. The article aims to characterize some key aspects of present-day migration from Mongolia to Australia. Materials and methods. The study employs a comprehensive methodology to analyze international and national statistics data from the United Nations, UNESCO, Governments of Australia and Mongolia, etc. It also involves discourse analyses of Russian-, Mongolian- and English-language print and online publications dealing with the migration of Mongolian citizens to Australia. Survey methods have proved as instrumental, e. g., expert surveys, informal interviews, and questionnaires. Field research was conducted in the summer of 2022. Results. The study reveals key characteristic features of Mongolian migration to Australia. Firstly, Mongolian migrants in Australia are a fastest growing group of foreign migrants. Currently, Australia is becoming an increasingly popular labor (third place after the Republic of Korea and the USA) and educational (fourth place after China, Korea and Japan) destination for Mongolian citizens. Secondly, the main driving force of labor migration from Mongolia to Australia is the economic motive; however, non-financial factors play an equally important role — low population density, similar to landscapes, high living standards and quality of life, favorable migration situation in the host society. Thirdly, educational migration from Mongolia to Australia, as well as labor migration, has a high potential, is associated with further employment prospects and professional self-realization for Mongolian citizens both at home and in the destination country. Labor and educational migration is stimulated by active special government programs within operating Australia-Mongolia agreements both in industrial/economic (primarily in mining) and humanitarian spheres (various scholarships, academic mobility). The countries anticipate an expansion of economic, cultural and educational cooperation, which shall make it possible to implement mutually beneficial projects

Fractionating the Plant Extract in Mini Volumes to Purify the Potential Antivirals from Terminalia Chebula

Background: The preliminary experiments indicated that a 30% aqueous extract of seeds of the Terminalia chebula has a significant neutralizing activity against tick-borne encephalitis virus (TBEV). In this study, we developed the most gentle approach to purify the antiviral substance. Methods and Results: The extract of T. chebula seeds was fractionated using gel filtration in Sephadex G-200 and G-50. The fractions were tested in vitro for the presence of a direct antiviral action against TBEV and profiled using liquid chromatography-mass spectrometry (LC-MS). Antiviral activity was detected in eight fractions from Sephadex G-200 and in three fractions from Sephadex G-50 gel filtration. The chromatogram of the most active Sephadex G-50 fraction exhibited three base peaks with a retention time of 3, 5 and 25.5 minutes. The MS of individual peaks revealed seven compounds with mass-to-charge ratios 114.03; 279.16; 290.91; 301.15; 579.3; 354.03, and 414.09 that were present at relatively high concentrations. Conclusion: In spite of a small sample, it was possible to detect antiviral activity in the fractionated plant extract using convenient virological methods, as well as to separate the components of the single virus-neutralizing fraction using the LC-MS approach. The purity of resulting preparation needs to be improved

Comparative Chromosome Mapping of Musk Ox and the X Chromosome among Some Bovidae Species

Bovidae, the largest family in Pecora infraorder, are characterized by a striking variability in diploid number of chromosomes between species and among individuals within a species. The bovid X chromosome is also remarkably variable, with several morphological types in the family. Here we built a detailed chromosome map of musk ox (Ovibos moschatus), a relic species originating from Pleistocene megafauna, with dromedary and human probes using chromosome painting. We trace chromosomal rearrangements during Bovidae evolution by comparing species already studied by chromosome painting. The musk ox karyotype differs from the ancestral pecoran karyotype by six fusions, one fission, and three inversions. We discuss changes in pecoran ancestral karyotype in the light of new painting data. Variations in the X chromosome structure of four bovid species nilgai bull (Boselaphus tragocamelus), saola (Pseudoryx nghetinhensis), gaur (Bos gaurus), and Kirk’s Dikdik (Madoqua kirkii) were further analyzed using 26 cattle BAC-clones. We found the duplication on the X in saola. We show main rearrangements leading to the formation of four types of bovid X: Bovinae type with derived cattle subtype formed by centromere reposition and Antilopinae type with Caprini subtype formed by inversion in XSB1
