This paper focuses on the problem of choosing the appropriate configuration of the chassis of the planetary rover to work in an environment similar to the moon. The space exploration of new planets will inevitably pose many new scientific and technical challenges to humanity. One of which will be a detailed study of the terrain and data analysis. For this purpose, we need such workstations and laboratories that can autonomously explore the area, moving through it and mastering new boundaries of future habitats. Therefore, in the future we will need reliable and mobile transport for different purposes. Planetary rovers will be in demand on celestial bodies as transport for various tasks, for example, research projects, for resource extraction. And as colonization continues, other applications will emerge.

In this paper, we describe the results of modeling rotation and studying the dynamics of the orbital motion of the SamSpace-1 nanosatellite. It is shown how the character of the angular motion of the apparatus changes depending on the selected orbit and external forces. As a mathematical model of the satellite’s rotation, the Euler dynamic equations are used, which are integrated using the fourth-order Runge - Kutta method. The results of solving the problem of determining the angular position of a nanosatellite are presented, which are used to construct the algorithm of the spacecraft’s motion control system and determine the mass-dimensional parameters of the executive means of the motion control system.

In th t a quantitative analysi evolution of a binary system e given paper we presen s of the WASP 1 WASP 1b with using a Non Minimal Model of Tidal Interaction. It is a logical continuation of the research of the system, the beginning of which was presented in [1]. Within the framework of the energy approach the potential corresponding to the tidal force acting on the element of a celestial body with mass dm and the magnitude of the static deformations of the spherical body surface were calculated here. The potential energy of the tidal interaction of a homogeneous weakly elongated ellipsoid of rotation and a massive point body was constructed. The Non Minimal model of tidal interaction of the two massive gravitating bodies was formulated. In the framework of the Lagrangian approach, using the results obtained above, the formulas for radial tidal force and it’s moment acting on the weakly elongated ellipsoid were built and closed system of differential equations describing evolution of the binary system were constructed. The initial conditions were seted and the procedures for the dimensioning and algebraic reduction of the equations system were realised for a unique solution of the equations system. A numerical analysis of the WASP 1 system evolution has been confirmed the conclusion of [1] - the exoplanet will inevitably fall on the surface of the star and will be terminated. The rest of the exoplanet lifetime is 887 million years, which is 14 million years more then estimation of the work [1] and is a more accurate result. The dependences of the radius of the orbit, stellar period of the star and exoplanet and its orbital period from time are demonstrated graphically. It is shown that orbital period will decrease from 2,52 days to 9,22 hours as a result of the exoplanet fall. The stellar period of the star will decrease on 5,6 days. After the fall, the period of rotation of the star will decrease to 18,25 37 days, and dissipation of the mechanical energy will be 4, 58 · 10 J! The latter value is comparable to energy explosion of nova star.

The article discusses the results of studying the complex of species of chalcidoid insects on the territory of the Samara region. The species diversity, abundance and stationary distribution data of insects of the family Eurytomidae are presented. We have analyse the trophic preferences of the study group and define their systematic diversity. Defined systematic diversity. New data which supplements information on the biodiversity of invertebrate animals in the region, are presented, that allows for biota monitoring studies within the framework of the «Study of Russian Biodiversity» program. New distribution data of harmful euritomid and promising entomophage species are received.

In our work, we obtained data on the number of ixodic ticks on the territory of such regions of the Samara region as Volzhsky and Neftegorsky. In the territory of these areas live many species of ticks, the main ones are Ixodes persulcatus and Ixodes ricinus. The frequency of occurrence in the Volzhsky region of the Ixodes persulcatus - 87 %, Ixodes ricinus - 13 %. The frequency of occurrence in the Neftegorsky region of the Ixodes persulcatus - 83,3 %, Ixodes ricinus - 16,7 %. We was studied the degree of infection of these individuals in the Volzhsky region, on the subject of encephalitis virus, which is - 15,3 %, in the Neftegorsky region - 12,1 %. According to research data for 2017 and 2018, we found that the total number of ticks in the 2017 year is more than 2018, this is due to climatic conditions, as well as the fact that during 2017-2018 no large-scale treatments with acaricides were carried out in the territory of the Volzhsky municipal district of the Samara region.

This article shows the effect of the precursor of the studied compound glycine on such parameters as heart rate, stroke volume of the heart, minute volume of the heart and the effect on compliance with Frank-Starling law. The study of glycine revealed similar, but more pronounced increase in the minute volume of the heart and heart rate. Effective concentrations for both substances were 10-6 M and 10-4 M. The article discusses the possibility of using N-acetylglycine as a safer diagnostic fluid for endoscopic heart operations.

This article presents the results of our experiments, by means of which the effect of potassium taurine on the preparation of a frog-isolated heart was studied. Studies conducted in model experiments allowed to determine the effect of potassium taurine on the main parameters of cardiac activity. A pronounced negative chronotropic and positive inotropic effect was found. The effective concentration of potassium taurine, at which there was a significant change in the studied parameters of cardiac activity, namely heart rate, stroke volume and the minute volume of the heart, was 10-4 M. The paper discusses the prospects for further research on taurine derivatives.

In this article talk about revelation period beginnings and fixing basic behavioral reaction at puma baby (Puma concolor, Linnaeus, 1771) in Samara zoo. We used passive watch. In a study chose basic behavior: sleep, comfortable behavior, eating behavior, play behavior. We founded distinct timetable beginnings and fixing basic behavioral reaction at puma baby in 16-47 days ago. In first time, training comfortable behavior and sleep, next training eating behavior, play behavior, territorial behavior, and defensive behavior.

The object of research is the Eisenhower matrix. This article uses of higher mathematics methods and techniques to reveal the conformities in matrix functional and their further development. Theory block generated on the basis of the output data of performed operations has been developed. The article provides the reader with an essential theorem and equations, and general matrix characteristics of its classical model. It is reported about some points, a consequence, and an important supposition. The determined dependences between considered magnitudes have been ascertained; these dependences form the theoretical basis, too. Also, some examples to check the mentioned theory are given, and summary has been made. In conclusion, it is repeated research results are given, and the key to further deeper exploration is provided.
