Evaluation of efficiency of repulsion in speed-and-strength types of athletics
Efficiency of repulsion in speed-and-strength types of athletics is an integral measure of skill, since the performance of repulsive movements involves interaction of almost all organs and body systems. Dynamic repulsion lays the foundation for high sports results and the conditions of effective interaction of internal and external forces. With the special test exercises, one can determine the level of functioning of individual systems, on which the result of an exercise depends, which during training sessions provides focused opportunity to influence the stimulation of individual systems, increasing their level of activity. The article presents an electromyographic evaluation of the effectiveness of repulsion during the high jump at a run. The implementation of this method will make it possible to objectively evaluate the level of technical skills of athletes and purposefully influence the improvement of basic biomechanical characteristics of sports exercises
Management of technical skills of highly qualified female athletes specializing in athletic jumps
Significant improvement of efficiency in managing technical mastery of female athletes-jumpers depend on the operational response to the emerging new technologies, their approbation and implementation in practice. The article introduces new opportunities for the use of simulators in the process of technical training of highly qualified female jumpers. The authors demonstrate the principal possibility of the applied use of the "facilitating-the-leadership" simulator for improvement of motor actions of female athletes. Obtained results show evident prospects of further expanding of the use of technology and simulators in the system of present-day preparation of highly skilled female athletes
Frontiers, challenges, and solutions in modeling of swift heavy ion effects in materials
Since a few breakthroughs in the fundamental understanding of the effects of
swift heavy ions (SHI) decelerating in the electronic stopping regime in the
matter have been achieved in the last decade, it motivated us to review the
state-of-the-art approaches in the modeling of SHI effects. The SHI track
kinetics occurs via several well-separated stages: from attoseconds in
ion-impact ionization depositing energy in a target, to femtoseconds of
electron transport and hole cascades, to picoseconds of lattice excitation and
response, to nanoseconds of atomic relaxation, and even longer macroscopic
reaction. Each stage requires its own approaches for quantitative description.
We discuss that understanding the links between the stages makes it possible to
describe the entire track kinetics within a multiscale model without fitting
procedures. The review focuses on the underlying physical mechanisms of each
process, the dominant effects they produce, and the limitations of the existing
approaches as well as various numerical techniques implementing these models.
It provides an overview of ab-initio-based modeling of the evolution of the
electronic properties; Monte Carlo simulations of nonequilibrium electronic
transport; molecular dynamics modeling of atomic reaction on the surface and in
the bulk; kinetic Mote Carlo of atomic defect kinetics; finite-difference
methods of tracks interaction with chemical solvents describing etching
kinetics. We outline the modern methods that couple these approaches into
multiscale multidisciplinary models and point to their bottlenecks, strengths,
and weaknesses. The analysis is accompanied by examples of important results
improving the understanding of track formation in various materials.
Summarizing the most recent advances in the field of the track formation
process, the review delivers a comprehensive picture and detailed understanding
of the phenomena.Comment: to be submitte

Innovative entrepreneurship in education: A new look in the students training content and existing problems
Β© 2016, Econjournals. All rights reserved.This article is aimed at scientific and methodological justification of studentsβ training content to innovative entrepreneurship. The leading method in the study of this problem is the analysis of studentsβ innovative entrepreneurship learning experience in Russian universities, which reveals the predominance of the traditional approach in the content of studentsβ training, as well as unwillingness of the teaching staff and students to innovate. The article identified the necessary competences in the field of innovative entrepreneurship (professional, business, functional, social and communicative), as well as entrepreneurial qualities (integrity, credibility, intelligence, presence of imagination, ability to make decision, ability to organize control, to provide justification of decisions); the methodology of studentsβ gradual of entrepreneurial competences is developed; factors blocking the effectiveness of the studentsβ entrepreneurial competencesβ formation are revealed
Physical Health of Males Residents from the Lowland Districts of Ukrainian Transcarpathia During the Post-Pubertal Period Depending on the Component Body Composition
Objective of the research was to determine the aerobic and anaerobic productivity of males
from the lowland districts of Ukrainian Transcarpathia during the post-pubertal period, depending on
the component composition of body weight.
Physical health status of 112 subjects was assessed by indicators of aerobic and anaerobic
productivity depending on the component composition of the body, which was determined by
impedance measurements. Physical health status was assessed by indicators of the aerobic
productivity of the body, namely, the maximum oxygen consumption was measured (VΠ2 max)
using the bicycle ergometry method. To evaluate the level of aerobic productivity, the Pyarnatβs
rating scale was used. Indicators of anaerobic productivity of the body were studied by: the power
of anaerobic alactic energy supply processes by the Peak Power Output in 10 s (WAnT10); the
power of anaerobic lactic energy supply processes by the Peak Power Output in 30 s (WAnT30),
using the Wingate anaerobic test described by Yu.M. Furman et al.
The highest level of aerobic productivity in terms of the relative value of maximal oxygen
consumption was found in young males who have normal body weight with a very high relative
content of skeletal muscle, a low relative content of fat, and a normal level of visceral fat. An
increase in the fat component has a negative effect on the body's aerobic energy supply among
young males from lowland districts of Ukrainian Transcarpathian region. On the contrary, the
growth of the muscle component of the body weight helps to increase the aerobic capacity of the
body. Among all examined males, no individuals with Β«excellentΒ» or Β«goodΒ» level of aerobic
productivity of the body were found
Optimization of routine immunohistochemical diagnostics of Hodgkinβs lymphoma in a large oncomorphology department
Π’ΠΎ determine the panel of immunohistochemical (IHC) markers, suitable for morphological confirmation of Hodgkin's lymphoma (HL). Materials and Methods: Verification of the 300 cases was based on histological and IHC analysis using antibodies to CD30, CD15, PAX-5, CD45, CD20, CD3, fascin, BLA-36. Results: 'Molecular portrait* of Reed-Stemberg cells in cases of 'classic' HL varied: the frequency of positivity to CD30 was 98%, C015 - 74%, PAX5 - 96%, CD45 - 3%, the CD20 -13%, fascin - 96%, BLA-36 - 78%. The most common histological types of HL was nodular sclerosis (NS). Less commonly diagnosed mixed-ceilularity HL - 90 (30%), the classic lymphocyte predominant -10 (3.3%) and lymphocyte depleted - 5 (1.7%). Nodular lymphocyte predominant variant was diagnosed in 5 (1.7%) cases. Conclusion: IHC method allows reliable verification of Hodgkin's lymphoma and its variant. We can recommend assessment of CD30, PAX5, CD15, fascin as first-line diagnostic markers of HL, and antibodies BLA36, CD20, CD45 as auxiliary markers.Π¦Π΅Π»Ρ: ΠΠΏΡΠ΅Π΄Π΅Π»ΠΈΡΡ ΠΏΠ°Π½Π΅Π»Ρ ΠΈΠΌΠΌΡΠ½ΠΎΠ³ΠΈΡΡΠΎΡ
