The article considers the features of study of the disciplines of the natural and mathematical cycle in pandemic conditions. The realities of today have led to a mass transition of participants of the educational process to distance learning which has certain positive features and shortcomings., {"references":["Наказ МОН України «Про затвердження Положення про дистанційне навчання».

The purpose of the article is to compare the place of biological physics in the curricula of higher medical institutions in Poland and Ukraine. Continuing our research, we focus on a more detailed analysis of the curricula of the Medical University of Lublin and the Medical Institute of Sumy State University. The article analyzes the curricula for the last five academic years, as well as work programs in biological physics. In Ukraine, curricula for the training of specialists in the qualification of physician in higher education are approved by the Minister of Health Protection. Study in Ukrainian universities of medical direction is determined by the industry standard of higher medical education, which is an industry normative document and defines the normative content of training, sets requirements for the content, volume and level of educational and professional training of a specialist of a particular educational and qualification level of a particular specialty. At the same time, the Standards of Education in Poland, approved by the Ministry of Science and Higher Education, determine general training issues, including hours of study and ECTS points, content of disciplines. In the higher educational establishments of Poland and Ukraine, we observe a different correlation between the theoretical and practical components of the discipline, that is, Polish medical universities pay more attention to the practical component. In recent academic years, classroom workload has been reduced for students in both Poland and Ukraine. Comparative analysis of work programs in biological physics also demonstrates the greater practical orientation of training in Polish higher educational establishments.

A nonlinear model of a viscoelastic medium is proposed, which describes softening of a thin layer of the ice surface during friction. The description of this transformation is based on the three following basic equations: the Kelvin-Voigt equation for a viscoelastic medium, the relaxation equations of Landau- Khalatnikov-type and for heat conductivity. It is revealed that mentioned equations coincide formally with the synergetic Lorenz system, where the order parameter is reduced to the shear strain, the stress acts as the conjugate field, and the temperature plays the role of the control parameter. The work further develops a nonlinear model of ice surface softening during friction, taking into account the spatial inhomogeneity of temperature in the equation of heat conductivity. In the framework of one-mode and adiabatic approximations an analytical soliton solution of a one-dimensional parabolic equation for the spatial normal distribution of shear strain to the ice surface is found. Due to the numerical solution of the one-dimensional Ginzburg- Landau differential equation, the distribution of friction force over the softened surface layer of ice is obtained and described. Two physical situations are considered: 1) the upper and lower surfaces move with equal velocities in opposite directions; 2) the upper surface is sheared along the fixed lower one. The coordinate dependencies of the friction force at different times are constructed and the evolution of the system to a stationary state is described. It is shown that the growth of time and background ice temperature leads to a sharper change of the friction force along the thickness of the premelted surface layer of ice, i.e. the relative shear velocity of the rubbing surfaces increases.
