    The uses of the elements of respiratory exercises as prevention of morbidity in preschool age children

    The technique with the use of elements of rhythmic gymnastics and respiratory exercises was introduced in preschool educational institutions of Adyghea Republic in the conditions of realization of health improving technologies. In order to study its efficiency a selection of children’s information was made and the morbidity analysis was carried out within a year. Observations show that children of experimental group get sick less often and are ill less long in comparison with contemporaries of control group.

    B&#228;cklund transformation and integrable potentials

    This paper discusses the Bäcklund transformation for the Korteweg-de Vries equation. We introduce the concept of a multiplicative integral and establish a connection between the Bäcklund transformation and integrable potentials. The meaning of Bäcklund transformation for differential equations is that there are substitutions that allow us to build more complex solutions from the more simple ones.

    On necessary stabilizability condition of unstable equilibria of linear systems by extended Pyragas’ delayed feedback

    In this paper a necessary effective stabilizability condition of unstable equilibria of linear controllable systems by extended Pyragas’ time-delayed feedback is obtained. It follows from this condition that if the number of positive eigenvalues of original matrix is odd, then the system can never be stabilized by generalized Pyragas’ delayed feedback. The condition obtained can be used in solving stabilization problem of unstable linear controllable systems by Pyragas’ delayed feedback and its extended form, as well as for local analysis of nonlinear control systems with chaotic behavior in the neighborhood of unstable equilibria.

    The kinematic Saint-Venant equation. The solution method

    The paper examines one-dimensional differential Saint-Venant model represented with diffusion and kinematic approximation, describing free water dynamic in open bed. For the kinematic approximation, which is a quasi-linear equation of the first order, there is a general analytical solution in stationary case. For the non-stationary case we developed a numerical algorithm. In the paper, the solution results are presented.

    Adequacy of Newton’s laws for problems of the dynamics of systems with holonomic constraints

    U. Stadler's proof about insufficiency of Newton’s laws for examination of a rigid double pendulum movement is analyzed. The authors suggest that a conclusion about violation of centrality of internal forces is incorrect. Completeness of axiomatics of classical mechanics for the solution of problems of the dynamics of material point systems with holonomic constraints is confirmed.

    The paper discusses the techniques of synthesis of mathematical criteria for an assessment of competence-based levels of learning a curriculum material. Analytical expressions of private and general criteria have been obtained in the form of Boolean functions on the basis of indicator binary logical variables. Realization of the obtained expressions by program or hardware way will allow us to expand the interface of data output devices about levels of learning a curriculum material to make the relevant administrative decisions on formation of professionally focused competences of trainees.
