In the course of management training of specialists in the field of physical education and sport, it is necessary to consider the aspects of tolerant attitude in social interactions and dealing with people through sports and physical activities. The aim of the paper is to develop a modern and coherent concept of tolerance in the managerial activity of PE instructors and sports coaches. The leading method in studying this problem is an exploratory approach, which includes evaluating the interrelation of physical, mental, personal, tolerant and administrative qualities of a future specialist and developing a shorter set of efficient current control criteria. The paper may be of use to the teachers engaged in the professional training of specialists in the field of physical education and sport. © JPES.

It has been found that a sinusoidal electric field is enhanced by a factor of more than 103 in two plane-parallel layers of different dielectrics placed between plates of a parallel-plate capacitor. The implementation of the enhancement of the electric field requires that the following two conditions should be satisfied: (1) one of the two layers should consist of finely dispersed dielectric particles with ionized donor centers formed on their surface and free electrons in their bulk, and (2) the dielectric permittivity of the powder should have a negative value. It has also been found that, in the powder layer, the enhancement of the electric field occurs simultaneously with its inversion. © 2017, Pleiades Publishing, Ltd.

Manufacturing stepped rods with segments of sizes proportional to stresses induced in operation is often used to reduce the material consumption in various fields of technology, for example, in the aircraft industry, where the requirements for the weight of structural elements are high. The vibration problems of continuous systems, i.e. systems which masses are considered distributed, are close to the resistance of materials and elasticity theory problems. They are described by partial differential equations. In this case, we consider a homogeneous isotropic material, obeying Hookes law. Of all the vibration problems of continuous systems, the transverse vibration problems of shafts and beams is of greatest practical importance. The simplest examples of vibrations of prismatic rods were studied in the 18th century in works on acoustics. But before solving problems of practical importance, the problems of stepped beams, it had taken another two hundred years and the development of approximate methods of solving differential equations. The paper presents a solution to the problem of determining the fundamental frequencies of bending vibrations of two-stepped rods with various boundary conditions, using the approximate Lagrange-Ritz method. The calculation error does not exceed 2.6 %. The fundamental frequency of vibration is defined considering different lengths and stiffness ratios of stepped rod segments. The obtained results can be used in solving practical problems in various fields of technology. © JVE INTERNATIONAL LTD.

International Journal of Bifurcation and Chaos | Year: 2016
The paper continues the application of the bifurcation analysis in the research on local climate dynamics based on processing the historically observed data on the daily average land surface air temperature. Since the analyzed data are from instrumental measurements, we are doing the experimental bifurcation analysis. In particular, we focus on the discussion where is the joint between the normal dynamics of local climate systems (norms) and situations with the potential to create damages (hazards)? We illustrate that, perhaps, the criteria for hazards (or violent and unfavorable weather factors) relate mainly to empirical considerations from human opinion, but not to the natural qualitative changes of climate dynamics. To build the bifurcation diagrams, we base on the unconventional conceptual model (HDS-model) which originates from the hysteresis regulator with double synchronization. The HDS-model is characterized by a variable structure with the competition between the amplitude quantization and the time quantization. Then the intermittency between three periodical processes is considered as the typical behavior of local climate systems instead of both chaos and quasi-periodicity in order to excuse the variety of local climate dynamics. From the known specific regularities of the HDS-model dynamics, we try to find a way to decompose the local behaviors into homogeneous units within the time sections with homogeneous dynamics. Here, we present the first results of such decomposition, where the quasi-homogeneous sections (QHS) are determined on the basis of the modified bifurcation diagrams, and the units are reconstructed within the limits connected with the problem of shape defects. Nevertheless, the proposed analysis of the local climate dynamics (QHS-analysis) allows to exhibit how the comparatively modest temperature differences between the mentioned units in an annual scale can step-by-step expand into the great temperature differences of the daily variability at a centennial scale. Then the norms and the hazards relate to the fundamentally different viewpoints, where the time sections of months and, especially, seasons distort the causal effects of natural dynamical processes. The specific circumstances to realize the qualitative changes of the local climate dynamics are summarized by the notion of a likely periodicity. That, in particular, allows to explain why 30-year averaging remains the most common rule so far, but the decadal averaging begins to substitute that rule. We believe that the QHS-analysis can be considered as the joint between the norms and the hazards from a bifurcation analysis viewpoint, where the causal effects of the local climate dynamics are projected into the customary timescale only at the last step. We believe that the results could be interesting to develop the fields connected with climatic change and risk assessment. © 2016 World Scientific Publishing Company.

Adaptive strategies of sporophytes of epilithic ferns are identified on the basis of research studies and literature data. A complex analysis of the photosynthetic apparatus of plants is carried out on different levels of its organization: frond, mesophyll cells, and plastids. The adaptation of sporophytes to the environment is also characterized on different levels of organization. Two morphofunctional (MFTs) and two physiological-functional types (PFTs) of ferns are isolated on the basis of their adaptability to epilithic living. This division reflects the adaptive peculiarities of ferns in certain biomes. © 2015, Pleiades Publishing, Ltd.

For the first time, the monocrystals of the bismuth-antimony alloys with impurity of gadolinium are received. Clusters, which are created, lead to a selective dispersion of holes. Therefore, the parity of contributions of different groups of current carriers in the phenomena of transfer changes. One of consequences of it is the increase in the thermoelectric properties of the bismuth-antimony alloys.

Based on a study of helophytic and hydrophytic ferns, as well as literature data, adaptive strategies of their sporophytes are identified. A complex analysis of the photosynthetic apparatus of the plants is carried out at different levels of its organization: (a) fronds, (b) mesophyll cells, and (c) plastid apparatus. Among these species, there is a selection of plants characterized by various biomorphs, active vegetative reproduction, and accelerated passing of ontogenetic phases. As a result, structures promoting aeration, the maintenance of an optimum water balance, and effective photosynthesis appear. © 2015, Pleiades Publishing, Ltd.
