    We investigate the masses (ground state energies) of neutral pseudoscalar and vector meson in SU(3)SU(3) lattice gauge theory in strong abelian magnetic field. The energy of ρ0\rho^0 meson with zero spin projection sz=0s_z=0 on the axis of the external magnetic field decreases, while the energies with non-zero spins sz=1s_z=-1 and +1+1 increase with the field. The energy of π0\pi^0 meson decrease as a function of the magnetic field. We calculated the magnetic polarizabilities of pseudoscalar and vector mesons for lattice volume 18418^4. For ρ0\rho^0 with spin sz=1|s_z|=1 and π0\pi^0 meson the extrapolations to zero lattice spacing have been done. We do not observe any evidence in favour of tachyonic mode existence.Comment: 9 pages, 13 figure

    The effectiveness of the development of individual countries within the conditions of accelerating scientific and technological progress, expanding the influence of globalisation and integration processes in the global socio-cultural space are very important during the exchange of international students. The purpose of the paper is to research the methodological foundations of the humanities education for international students as an alternative to transhumanist ideology. In the framework of general scientific research methods, a paradigmatic approach is used as a factor analysis of students' educational processes. Particular attention is paid to the substantiation of the methodological foundations of the education humanisation on the basis of modern ontologically anthropological and religious-anthropological achievements of the philosophical field of knowledge. In this regard, the thesis is accepted that the artificially imposed transhumanist ideology performs a key integrating function when considering the practice of education of international students. The novelty of the study is due to a discussion of the contradictions caused by all-round technocratisation and informatisation, the fall of moral standards, and the degradation of human behavior. The practical significance of the study is determined by the need to develop a different pedagogy and model of education for modern students

    Objectives. To conduct a comparative analysis of the features of a fermentation unit design for obtaining bioprotein from natural gas and determine the main technical and structural solutions used in the development of fermentation apparatus, which vary according to the method of organizing hydraulic and mass transfer processes.Results. An analysis of publications devoted to the problem of developing technological equipment for conducting the process of obtaining a bioprotein from natural gas is presented. Using the comparative analysis, the key features of bioreactors and their internal elements are indicated according to the method of organizing the hydrodynamic regime. The main approaches to the technological development of fermentation units for obtaining bioprotein from natural gas are described and technical solutions used in the implementation of these structures are identified.Conclusions. Fermenter designs for the cultivation of methane-oxidizing microorganisms vary according to the main approaches for implementing the hydraulic regime inside the apparatus. While one class of fermentation systems is based on the principle of volumetric mixing in the working space of the apparatus, with the possibility of including external circulation circuits, additional tanks, and auxiliary bioreactors in the system, the other main class relies on the principle of flow (displacement) in the tube space with subsequent release of the gas phase from the circulating culture liquid.Цели. Провести сравнительный анализ особенностей аппаратурного оформления ферментационного узла процесса получения биопротеина из природного газа. Определить основные технические и конструкционные решения, применяемые при разработке ферментационных аппаратов, различающиеся по способу организации гидравлических и массообменных процессов.Результаты. Проведен анализ литературы, посвященной проблеме разработки технологической аппаратуры для получения биопротеина из природного газа. С использованием метода сравнительного анализа были выявлены ключевые особенности конструкций биореакторов и их внутренних элементов, отличающихся способом организации гидродинамического режима в аппаратах. Описаны различные подходы к разработке оборудования для ферментационного узла процесса получения биопротеина, а также определены основные технические решения, используемые при создании данных конструкций.Выводы. Установлено, что большинство конструкций ферментационных аппаратов, предназначенных для культивирования метанокисляющих микроорганизмов, базируется на реализации гидравлического режима внутри аппарата. Часть ферментационных систем построена на принципе объемного перемешивания в рабочем пространстве аппарата с возможным включением в систему внешних циркуляционных контуров, дополнительных емкостей и вспомогательных биореакторов, другая часть использует принцип движения потока (вытеснения) в трубном пространстве, с последующим выделением газовой фазы из рециркулирующей культуральной жидкости
