The paper discusses the concept and features of life quality as a socio-economic category. The main signs of quality of life of the population are shown. The analysis of different methodologies to measure indicators of life quality is given. It is shown that the most authoritative measure of the quality of life in the world is the “Human Development Index” (HDI). The main task of authorities at different levels to improve the quality of life of the population is described

Competitiveness indicators of catering business entities : the case of Russia

Purpose: The article analyzes the existing marketing strategies in catering and define their influence on the competitiveness level of catering business entities in Russia. Design/Methodology/Approach: This article is dedicated to generalizing papers on the problems of catering marketing strategy formation. The object of the research is marketing strategies in catering and their influence on the competitiveness level of the entities. Findings: The novelty of the research is an algorithm of evaluation of the competitiveness level and marketing strategy adjustment of operating catering business entities based on the analysis of their major performance indicators. The algorithm with its system of certain indicators allows defining the competitiveness level, selecting and adjusting marketing strategies and sub-strategies, and, thus, enhancing the effectiveness of catering business entity performance. Practical implications: Flexibility and adaptiveness of this system entails that any catering business entity can select priority indicators from it and then calculate them to adjust marketing strategies and sub-strategies based on data obtained in the meantime. Originality/Value: The value lies in the disclosure of industry specifics of strategic marketing management in a definite economic activity considering essential strategic and operational factors which determine ultimate economic effectiveness of target marketing exposures.peer-reviewe

Extraction processing of concentrated solutions of uranyl nitrate with high impurities content

Process flowsheet of recycling uranium concentrated solutions with its purification from insoluble impurities of iron, silicon, molybdenum, calcium oxides and hydroxides and soluble impurities with application of centrifugal extractors cascade has been developed and suggested for commercial introduction. The process was carried out at extractant saturation (30 % tributyl phosphate in hydrocarbon diluent) in extraction assembly lower than a limiting level (85...95 g/l) and in wash assembly - at limiting saturation (up to 120 g/l). As a result the waste uranium content in water-tail solutions 0,01...0,04 g/l and minimal content of impurities in re-extractors is provide

Magnetic phase diagram and possible Kitaev-like behavior of honeycomb-lattice antimonate Na3Co2SbO6

Recent theoretical studies have suggested that Kitaev physics and such effects as formation of a mysterious spin-liquid state can be expected not only in RuCl3 and iridates, but also in conventional $3d$ transition metal compounds. Using DC and AC magnetometry, thermodynamic and $^{23}$Na nuclear magnetic resonance measurements (NMR) we studied such a candidate material Na3Co2SbO6 . A full phase diagram of Na3Co2SbO6 in a wide range of magnetic fields and temperatures is presented. The results demonstrate transformation of the magnetic structure realized at low-temperature and suppression of the AFM order under the external field, the gradual development of the saturation phase, as well as evidence of gapped spin-liquid-like behavior in certain parts of the phase diagram

Asymmetric Faraday Effect in a Magnetophotonic Crystal

It is widely known that the magneto-optical Faraday effect is linear in magnetization and therefore the Faraday angles for the states with opposite magnetizations are of opposite sign but equal in modulus. Here we experimentally study propagation of light through a one-dimensional all-garnet magnetophotonic crystal to demonstrate an asymmetric Faraday effect (AFE) for which Faraday angles for opposite magnetic states differ not only in sign but in the absolute value as well. AFE appears in the vicinity of the cavity resonance for an oblique incidence of light which plane of polarization is inclined to the incidence plane. Under proper incidence and polarization angles the magnitude of AFE could be very large reaching 30% of the absolute value of the Faraday effect. The effect originates from the difference in Q-factors for p- and s- polarized cavity modes that breaks the symmetry between the two opposite directions of polarization rotation. The discovered AFE is of prime importance for nanoscale magnonics and optomagnetism.Comment: Supplementary information provided after the main tex

Identification of weeds from the cabbage family (Brassicaceae) found in the agrocenoses of the Russian Federation

Members of the Brassicaceae family are of great significance as weeds and invasive plants; they are one of the leading families of the alien fraction in the segetal floras of various regions of Russia. Among the cruciferous weeds growing over Russia, there are many species that are wild relatives to cultivated plants. Some cultivated species grow outside of their cultivation areas as ruderal and segetal plants. Among the cruciferous plants growing in Russia, 28 species out of 19 genera are regulated as harmful organisms in 33 different countries. Most of the species from this list are widespread weeds in Russia.To establish the presence of Brassicaceae species in Russian agrocenoses, we analyzed published sources, herbarium materials stored in the Russian leading herbaria, and materials collected by the authors during field explorations in 2017–2022 in 19 subject entities of the Russian Federation.  Identification of cruciferous plants is often a rather difficult task, so the goal of this work was to develop a convenient identification key that would make in possible to identify weeds of this family found in Russian agrocenoses.  Most of the available keys are designed for fruit-bearing specimens of cruciferous plants. For phytosanitary purposes, it is important to identify plants prior to their fruiting period. Therefore, we additionally used the characters of flowering plants (including their vegetative organs) enabling us to identify cruciferous plants at the flowering stage. Based on such features, a table was made, which included all weedy species of Brassicaceae found in agrocenoses within Russia (83 species in total). On the basis of this table, an identification key was produced for the identification of genera and some species of weedy cruciferous plants. Afterwards, fractional species-specific keys were made for the genera containing species controllable in importing countries

Effect of additions of zinc stearate on the properties of sintered Nd-Fe-B magnets

Zinc stearate additions have been used to increase the remanence of sintered Nd-Fe-B magnets produced by the powder metallurgy without powder pressing. Zinc stearate acts as an internal lubricant, i.e., it decreases the friction forces between the particles and favors an increase in the degree of texture of the powders, which is induced by the magnetic field. It is shown that the density and the magnetic hysteresis characteristics of sintered magnets produced using additions of 0.15 wt % zinc stearate exceeds the corresponding values obtained for magnets produced without this addition at a filling density of powders in containers of more than 2.9 and 3.0 g/cm3 in dry and wet states, respectively. Using additions of zinc stearate in the amount of 0.15% with respect to the weight of the powder, magnets with a density of 7.55 g/cm3, B r = 14.02 kG, H c = 7.91 kOe, and (BH)max = 46.1 MG Oe have been produced. © 2013 Pleiades Publishing, Ltd
