    Liquid-gas phase transition at and below the critical point

    Full text link
    This article is a continuation of our previous works (see Yukhnovskii I.R. et al., J. Stat. Phys, 1995, 80, 405 and references therein), where we have described the behavior of a simple system of interacting particles in the region of temperatures at and about the critical point, T \geqslant T_{c}. Now we present a description of the behavior of the system at the critical point (T_{c}, \eta_{c}) and in the region below the critical point. The calculation is carried out from the first principles. The expression for the grand canonical partition function is brought to the functional integrals defined on the set of collective variables. The Ising-like form is singled out. Below T_{c}, when a gas-liquid system undergoes a phase transition of the first order, i.e., boiling, a "jump" occurs from the "extreme" high probability gas state to the "extreme" high probability liquid state, releasing or absorbing the latent heat of the transition. The phase equilibria conditions are also derived.Comment: 23 pages, 9 figure

    Aim. The synthesis of two degree of freedom robust two circuit system of active shielding of magnetic field with circular spacetime characteristic, generated by overhead power lines with "triangle" type of phase conductors arrangements for reducing the magnetic flux density to the sanitary standards level and to reducing the sensitivity of the system to plant parameters uncertainty. Methodology. The synthesis is based on the multi-criteria game decision, in which the payoff vector is calculated on the basis of the Maxwell equations quasi-stationary approximation solutions. The game decision is based on the stochastic particles multiswarm optimization algorithms. The initial parameters for the synthesis by system of active shielding are the location of the overhead power lines with respect to the shielding space, geometry and number of shielding coils, operating currents, as well as the size of the shielding space and magnetic flux density normative value, which should be achieved as a result of shielding. The objective of the synthesis is to determine their number, configuration, spatial arrangementand and shielding coils currents, setting algorithm of the control systems as well as the resulting of the magnetic flux density value at the shielding space. Results. Computer simulation and field experimental research results of two degree of freedom robust two circuit system of active shielding of magnetic field, generated by overhead power lines with Β«triangleΒ» type of phase conductors arrangements are given. The possibility of initial magnetic flux density level reducing and system sensitivity reducing to the plant parameters uncertainty is shown. Originality. For the first time the synthesis, theoretical and experimental research of two degree of freedom robust two -circuit t system of active shielding of magnetic field generated by single-circuit overhead power line with phase conductors triangular arrangements carried out. Practical value. Practical recommendations from the point of view of the practical implementation on reasonable choice of the spatial arrangement of two shielding coils of robust two -circuit system of active shielding of the magnetic field with circular space-time characteristic generated by single-circuit overhead power line with phase conductors triangular arrangements are given.ЦСль.

    Aim. Reducing of magnetic flux density of magnetic field in multi-storey building, generated by overhead power lines to the sanitary standards level by active shielding means. The tasks of the work are the synthesis, computer simulation and experimental research of three-circuits system of active shielding, which includes three shielding coils. Methodology. When synthesizing the system of active shielding of magnetic field, are determined their number, configuration, spatial arrangement and of shielding coils as well as the shielding coils currents and resulting magnetic flux density value in the shielding space. The synthesis is based on the multi-criteria game decision, in which the payoff vector is calculated on the basis on quasi-stationary approximation solutions of the Maxwell equations. The game decision is based on the stochastic particles multiswarm optimization algorithms. Results. Computer simulation and experimental research of three-circuit system of active shielding of magnetic field, generated by overhead power lines with phase conductors triangle arrangements in multi-storey building are given. The possibility of initial magnetic flux density level reducing in multi-storey building to the sanitary standards level is shown. Originality. For the first time to reducing of magnetic flux density of magnetic field in multi-storey building the synthesis, computer simulation and experimental research of three-circuit system of active shielding of magnetic field generated by single-circuit overhead power line with phase conductors triangular arrangements carried out. Practical value. Practical recommendations from the point of view of the practical implementation on reasonable choice of the spatial arrangement of three shielding coils of three-circuit system of active shielding of the magnetic field generated by single-circuit overhead power line with phase conductors triangular arrangements in multi-storey building are given.ЦСль.

    Sociocultural Situation in Villages of Providensky Urban Okrug (Chukotka) through the Eyes of Their Residents: Analyzing Field Materials of 2021. Part Two

    Get PDF
    Introduction. Due to remoteness, limited accessibility and ethnocultural uniqueness, Chukotka used to be β€” and still is β€” a particular region of Russia. In Chukotka Autonomous Okrug, the nationwide and specifically β€˜northern’ political, economic, social and cultural processes are paralleled by vivid local specifics manifested in all life spheres. The work introduces accounts of the current sociocultural situation articulated by rural residents of Providensky Urban Okrug. Goals. The paper aims to deliver native inhabitants’ opinions on village life, including which realms of social agenda they tend to view as promising, their actual challenges, controversies, and threats. Materials and methods. The study focuses on field materials collected in the town of Provideniya, villages of Enmelen, Nunligran, Sireniki, Novoye Chaplino, and Yanrakynnot in 2021. Special attention is paid to publications characterizing the socioeconomic situation of Chukotka’s indigenous peoples. The problems identified in the article have been approached by a number of ethnographers, sociologists and anthropologists of different generations from a variety of angles. So, the latter serve a β€˜starting point’ for understanding and analyzing the current sociocultural situation in Providensky Urban Okrug of (Chukotka Autonomous Okrug). Part One of the article reviewed publications, summarized results of expeditions to Providensky District, briefly described traditional occupations of rural dwellers, and characterized the sociocultural situation in the villages of Enmelen, Sireniki and Nunligran. Part Two deals with the sociocultural situation in the villages of Novoye Chaplino and Yanrakynnot. Conclusions. According to the Russian Census of 2020, the population of Providensky Urban Okrug is 3,707 people, of which 2,140 live in urban areas and 1,567 β€” in rural ones. About half of the residents are ethnic Chukchis (36.7%) and Eskimos (Siberian Yupiks; 19,1 %). The last ten years have witnessed a minor population growth only in two settlements β€” town of Provideniya and village of Novoye Chaplino. The main reasons of rural depopulation are low living standards, deterioration of housing facilities, underdevelopment of rural infrastructure, poor educational and medical services, under- and unemployment, low wages, isolation and limited leisure time opportunities. All the interviewed residents stress the importance of sea-hunting industry as a basis of present-day life in the villages. Elders still hope for further development of reindeer breeding and related sectors. The language situation is characterized by a virtually complete displacement of native languages in family and everyday communicative practices
