    The article describes the prospects for creating an informational adaptive automated learning system (based on the English Language) using advanced artificial intelligence technologies. In particular, the work shows that the quality of education largely depends on the form of educational content and the parameters of the learning object (a student) associated with its perception of informatio

    Objective: to evaluate the effectiveness of psychocorrection based on the methods of self­regulation in athletes.Materials and methods: the effectiveness was evaluated on 104 male athletes who had an optimal level of psychoemotional state of the body during a background examination by electroencephalography (EEG). The subjects were randomly assigned to three groups of psychocorrection: control, EEGtraining, and VR­therapy. Mathematical and statistical processing was carried out in Statistica 7.Results: the average values of the wave intensity index (WII) after psychological correction using the following methods: EEG­training and VRtherapy showed positive EEG dynamics in athletes of the second group (EEG­training) 65,6 % (21) and the third group (Vr­therapy) 73,8 % (31) of the subjects, respectively. Whereas in the control group, self­healing was recorded in 9 (30 %) athletes without psychocorrection procedures.Conclusion: the quantitative criterion of WII is a universal informative indicator of the functional activity of the brain for evaluating the effectiveness of psychocorrection aimed at optimizing the psychoemotional state. Psychocorrection of athletes using EEG­training and VR­therapy provides efficiency in 73.8 and 65.6 % of cases, which significantly softens pre­start tension as a result of reducing anxiety and restoring the psychoemotional state of the body to an optimal level by involving the psychological reserve

    In this study, methods for intensifying micro- and ultrafiltration processes by controlling the concentration-polarization effect are considered and studied. The negative effect of concentration polarization on the process of separation of the filtered liquid and on the membrane surface is described (due to the increase in concentration, the selectivity and specific productivity of the membrane surface decrease). The physical picture of the flowing phenomena in a flat membrane channel with known geometric dimensions is considered, four sections with different effects on the filtration process are identified. The equation of material balance is analyzed by introducing boundary conditions into the criterion equation of material balance, with the aim of finding opportunities for mass transfer. It is revealed that the mass transfer coefficient km decreases, due to the growth of the thickness of the boundary layer. The main parameters significantly influencing the process of microfiltration are the flow rates G of the initial solution, the mass transfer coefficient km, and with decreasing km decreases and G. The analysis of theoretical and experimental data is carried out showing that the decisive role in the course of the microfiltration process is played by the motion regime of the initial solution, Physical-chemical properties, geometry of the membrane channel. The prospects for using the pulsating field in bioreactors and the need for a conceptual approach for the development of promising membrane devices are grounded. The need to create membranes of complex geometric shapes with the possibility of placing turbulent devices in them and the possibility of moving them relative to each other is considered, creating channels of variable cross-section, which will lead to the appearance of a sufficient number of possibilities for creating hydrodynamic instabilities of various intensities. The article touches upon the application of pulsation regimes of destruction or loosening of the polarization layer by means of reciprocating motion of the concentrate, periodic membrane regeneration by tangential pulsating flow or by using reverse pumping

    It is common knowledge that from the cellular level upwards all vital functions of the body represent a continuous chain of adaptive reactions based on the use of energy. The leading element in non-specific mechanisms of adaptation is stress reaction [1]. In the early stages of stress development, the electrical activity of limbic-reticular structures of the brain changes first, followed by the activation of somatovegetative reactions [2]
