FORMATION OF RISK-BALANCED STYLE OF PROFESSIONAL ACTIVITY AMONG UNIVERSITY STUDENTS

The basis of the sustainable development of society with ever-growing scientific and technical progress is noxology as a science about the dangers of the world, since the risk of being in modern society is higher than ever. In this regard, a scientific noxospheric picture of the world is being formed as an integrative knowledge system, which should be the basis for the formation of a new, noxological worldview, in which security is the main value norm of risk-oriented thinking. The article is aimed at the theoretical substantiation of the necessity of developing a risk-balanced style of professional activity among university students on the basis of risk-thinking as an objective property of the personality. The article also reveals the authors’ concept of the noxological consciousness and explains the term of a risk-balanced style of professional activity. The definition, structure and main constituent elements of this personal phenomenon are given. It is determined that noxological style of professional activity includes such components as risk-thinking, self-regulation, intellectual features and capabilities, “labor model”, individual biological rhythms, will, as well as habits and special techniques of activity. Various characteristics of risks in the professional activity of a specialist are considered. Based on the analysis of scientific and pedagogical literature on the problem and the method of observation, the modeling of the pedagogical system of training a specialist with a risk-balanced style of professional activity is presented, the effectiveness of which is confirmed by the formative experiment

RESONANT ELECTROMAGNETIC PROCESSES AT UNSTABLE OPERATION OF SLIDING CURRENT COLLECTOR UNITS OF TURBOGENERATOR

The article is devoted to study of the resonance electromagnetic oscillations arising during unstable operation of the sliding current collection unit of turbo-generators. Mathematical modeling of these processes is carried out. It has been established that it is these processes that are the main cause of increased sparking and “ring fire” or “breakdown of commutation” on contact rings

INDICATORS OF FORMALIZED DESCRIPTION QUALITY AND ANALYSIS OF PRODUCTION TECHNOLOGIES

This paper discusses conceptual basis for assessment and analysis of model quality relating to formalized description of technologies. The authors give indicators used to assess formalized and textual descriptions of technologies. They raise some questions concerning the analysis of technologies that enable to make a list of indicators. The paper examines decomposition structures of specific technologies and provides the calculations of introduced coefficients.

Challenges in QCD matter physics - The Compressed Baryonic Matter experiment at FAIR

Substantial experimental and theoretical efforts worldwide are devoted to explore the phase diagram of strongly interacting matter. At LHC and top RHIC energies, QCD matter is studied at very high temperatures and nearly vanishing net-baryon densities. There is evidence that a Quark-Gluon-Plasma (QGP) was created at experiments at RHIC and LHC. The transition from the QGP back to the hadron gas is found to be a smooth cross over. For larger net-baryon densities and lower temperatures, it is expected that the QCD phase diagram exhibits a rich structure, such as a first-order phase transition between hadronic and partonic matter which terminates in a critical point, or exotic phases like quarkyonic matter. The discovery of these landmarks would be a breakthrough in our understanding of the strong interaction and is therefore in the focus of various high-energy heavy-ion research programs. The Compressed Baryonic Matter (CBM) experiment at FAIR will play a unique role in the exploration of the QCD phase diagram in the region of high net-baryon densities, because it is designed to run at unprecedented interaction rates. High-rate operation is the key prerequisite for high-precision measurements of multi-differential observables and of rare diagnostic probes which are sensitive to the dense phase of the nuclear fireball. The goal of the CBM experiment at SIS100 (sqrt(s_NN) = 2.7 - 4.9 GeV) is to discover fundamental properties of QCD matter: the phase structure at large baryon-chemical potentials (mu_B > 500 MeV), effects of chiral symmetry, and the equation-of-state at high density as it is expected to occur in the core of neutron stars. In this article, we review the motivation for and the physics programme of CBM, including activities before the start of data taking in 2022, in the context of the worldwide efforts to explore high-density QCD matter.Comment: 15 pages, 11 figures.

Transfortation of spacial-time structure of laser pulses during nonstationary induced scatterings and four-wave interactions

The investigation is concerned with solid-state lasers and optical glassamplifier, semiconductors, liquid and gas media. The asymmetry of intensity distribution relative to the diffraction tolerance, conditions of prevaling of nonlinearity mechanisms, narrowing of the radiation pattern and limiting possibilities of pulse compressors being polywave sources of pulse synchronization of various duration in the range from 10 ns to 1 ps have been created. The experimental pototypes of cascade IS-compressors with amplifiers of output peak-second monopulses have been usedAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
