DEVELOPMENT OF THE EXPERIMENTAL METHOD FOR THE ANALYSIS OF QUANTITATIVE CHARACTERISTICS OF THE TEXTURE AND ANISOTROPY OF PROPERTES OF GPU ALLOYS BY THE METHOD OF REVERSE POLE FIGURES

Разработка новых высокотехнологичных материалов для ракетно-космической и авиационной отраслей промышленности, атомной энергетики связана с созданием технологий, обеспечивающих получение требуемого комплекса технологических и эксплуатационных свойств изделий и конструкций. Широкое применение в этих отраслях промышленности нашли сплавы титана и циркония. Характерной особенностью этих сплавов является кристаллографическая текстура, которая практически полностью определяет анизотропию физико-механических свойств полуфабрикатов и изделий из них. Необходимость управления текстурообразованием обусловливает развитие методик, позволяющих проводить количественный анализ кристаллографических ориентировок.The development of new high-tech materials for the rocket and space and aviation industries, nuclear power is associated with the creation of technologies that ensure the required set of technological and operational properties of products. Alloys of titanium and zirconium were widely used in these industries. A characteristic feature of these alloys is the crystallographic texture. The need to control texture formation determines the development of techniques that allow for the quantitative analysis of crystallographic orientations

COMPARATIVE STUDIES OF VR SIMULATOR EFFECTIVENESS AND ALTERNATIVE PRESENTATION SKILLS TRAINING METHODS

The paper analyzes the results of the experiment (conducted at the School of Advanced Studies (SAS), the University of Tyumen in collaboration with the Saint Petersburg State University “Digital Technologies in Education” Science and education center from 23.05.2022 to 28.05.2022) comparing teaching English language public presentation skills using a VR simulator in comparison with self-study and exercises with the instructor. The researched teaching methods are compared for effectiveness in teaching various skills of the set (emotional control, speech structuration and contact with the audience).Анализируются результаты эксперимента обучения навыкам публичных выступлений на английском языке с использованием VR-тренажера в сравнении с самообучением и взаимодействием с тренером, проведенного в Школе перспективных исследований Тюменского государственного университета совместно с сотрудниками Научнообразовательного центра «Цифровые технологии в образовании» Санкт-Петербургского государственного университета в период с 23.05.2022 по 28.05.2022. Рассматривается сравнительная эффективность сравниваемых методов обучения для улучшения различных навыков (эмоционального контроля, структурирования речи, контакта с аудиторией)

Construction, assembly and testing of the ATLAS hadronic end-cap calorimeter

The construction and assembly of the four wheels of the ATLAS hadronic end-cap calorimeter and their insertion into the two end-cap cryostats are described. The results of the qualification tests prior to installation of the two cryostats in the ATLAS experimental cavern are reviewed

Poststreptococcal arthritis in teenagers

During 1995-1999 autumn-winter periods 300 teenagers with signs of acute respiratory disease (ARD) were examined. 38% from them had group A p-hemolytic streptococcus (GABS) and elevation of anti- streptolysine-O antibodies titers what comply with definite streptococcal infection criteria. Arthritis was revealed and immunologically characterized in 35 teenagers with streptococcal pharyngitis. Pts with non streptococcal pharingitis did not have arthritis. These results allowed to describe clinical and immunological signs of poststreptococcal arthritis for the first time in our land. These signs included asymmetrical non migrating arthritis lasting from 8 to 156 days with primary involvement of large (knee) and less frequently - small joints. Synovitis manifested with joint pain and swelling. It was confirmed by US examination and differed from migrating arthritis in acute rheumatic fever (ARF). According to WHO recommendations teenagers with definite streptococcal infection received combined treatment - single injection of bicillin-5 with subsequent treatment with fenoximethylpenicilline. Cultures and blood immunologic examination in a month and later after treatment gave negative results in 90,5% of pts. Described disease or syndrome associated with acute upper respiratory infection in teenagers differ from ARF
