Methodological Approach to Planning and Financing the Fixed Capital Reproduction for Sustainable Development of the Fishing Industry

The article presents the results of scientific and research work on the creation of a methodological approach to the analysis of fixed capital reproduction for fishing enterprises. This study is relevant due to the fact that the fishery complex of the Russian Federation is currently called upon to provide a solution to many political and economic problems, which, in particular, include transition to an innovative type of industrial production, provision of food security, as well as maintenance of a favorable state of aquatic biological resources. Due to this industry's high capital intensity, the issues of choosing a methodology that make it possible to rationally control the fixed capital reproduction of fishing enterprises become especially important, which is likely based on an analysis of existing methods that allow planning these processes. The advantages of the developed methodological approach include the establishment of uniform methodological principles used to determine the economic efficiency of investments, new equipment, inventions and rationalization proposals, more accurate consideration of the time factor concerning the determination of the integral economic effect (for the entire service life of labor means), as well as the factor time by bringing one-time and ongoing costs for the creation and implementation of new and necessary equipment and the results of their application to one point in time (the beginning of the accounting year). The article includes the main advantages and disadvantages of financing the reproduction processes possible ways

The article is devoted to the problem of individual customer service quality improvement in the field of provided deposit and credit services. This problem is a priority in determining any commercial bank strategy, since both deposit and credit policies determine the effectiveness of a credit institution development, which largely depends on the level of customer satisfaction. This study aims to determine the management aspects of the deposit and credit policy improvement in the field of commercial bank customer servicing. In the course of the work, they used the elements of system analysis, statistical research methods (summary and grouping, calculation of average values), and SWOT analysis. To assess customer satisfaction, the authors studied the Internet reviews of the largest regional bank of the Primorsky Territory of Russia - PJSC SKB of Primorye "Primsotsbank". The use of the indicated methods in the study made it possible to assess the quality of services provided to clients, identify the problems in their service sector, and develop the measures for their elimination. The results obtained are the basis for making managerial decisions to improve the deposit and credit policy of the studied bank and can be used in commercial banks' practice

Motivation in personnel management of a trading enterprise

Purpose: Investigating the problems of personnel motivation efficiency as one of the most significant factors of the success of an enterprise at the present stage of development of the Russian economy, the authors consider expedient to consider the theory and practice of the personnel motivation system in a commercial enterprise. Design: General scientific (analysis, synthesis, comparison), and special methods of research (economic and statistical, balance sheet, design-calculation and other), document analysis, questioning, and others were used during the study. Findings: The authors revealed that the trading company should focus on the development of a system of motivation in two directions: the improvement of material motivation of staff and the improvement of non-material motivation of staff. Improving the proposed system of staff motivation will allow the company to create a favorable atmosphere in the team, increasing turnover. Practical implications: The obtained results can be used by the head of the enterprise when developing plans to improve the management system and increase investment attractiveness. Originality: This article analyzes the theoretical foundations of motivation in personnel management. Given the organizational and economic characteristics of the trading enterprise, identified the existing system of motivation in the enterprise.peer-reviewe

Frequencies of wave packets of whistler-mode chorus inside its source region: a case study

Whistler-mode chorus is a structured wave emission observed in the Earth's magnetosphere in a frequency range from a few hundreds of Hz to several kHz. We investigate wave packets of chorus using high-resolution measurements recorded by the WBD instrument on board the four Cluster spacecraft. A night-side chorus event observed during geomagnetically disturbed conditions is analyzed. We identify lower and upper frequencies for a large number of individual chorus wave packets inside the chorus source region. We investigate how these observations are related to the central position of the chorus source which has been previously estimated from the Poynting flux measurements. We observe typical frequency bandwidths of chorus of approximately 10% of the local electron cyclotron frequency. Observed time scales are around 0.1 s for the individual wave packets. Our results indicate a lower occurrence probability for lower frequencies in the vicinity of the central position of the source compared to measurements recorded closer to the outer boundaries of the source. This is in agreement with recent research based on the backward wave oscillator theory

Structural and Functional Organization of the Vestibular Apparatus in Rats Subjected to Weightlessness for 19.5 Days Aboard the Kosmos-782 Satellite

The vestibular apparatus was investigated in rats subjected to weightlessness for 19.5 days. The vestibular apparatus was removed and its sections were fixed in a glutaraldehyde solution for investigation by light and electron microscopes. Structural and functional charges were noted in the otolith portions of the ear, with the otolith particles clinging to the utricular receptor surface and with the peripheral arrangement of the nucleolus in the nuclei of the receptor cells. It is possible that increased edema of the vestibular tissue resulted in the destruction of some receptor cells and in changes in the form and structure of the otolith. In the horizontal crista, the capula was separated

Anomalous and Spin Hall Effects in a Magnetic Tunnel Junction with Rashba Spin-Orbit Coupling

Anomalous and spin Hall effects are investigated theoretically for a magnetic tunnel junction where the applied voltage produces a Rashba spin-or bit coupling within the tunneling barrier layer. The ferromagnetic electrodes are the source of the spin-polarized current. The tunneling electrons experience a spin-orbit coupling inside the barrier due to the applied electrical field. Charge and spin Hall currents are calculated as functions of the position inside the barrier and the angle between the magnetizations of the electrodes. We find that both charge and spin Hall currents are located inside the barrier near the in terfaces. The dependence of the currents on magnetic configuration of the magnetic tunnel junction makes possible the manipulation by the Hall currents via rotation of the magnetization of the electrodes.Comment: 10 pages, 4 figure

Изучение закономерностей осаждения тонких сорбционно-активных пленок диоксида марганца на различных полимерных носителях

Manganese dioxide (MnO2) is used as a sorption material for the isolation of a wide range of substances from aqueous media. A number of composite materials containing MnO2 are known, while in the scientific literature there are no systematic data on the possibilities of obtaining flat thin-layer sorbents of manganese dioxide on other polymer carriers. In this study, a number of flat thin-layer sorbents, consisting of manganese dioxide deposited on the surface of various carriers, were synthesized. The most common flat materials were used as carriers - polyethylene (PE), polypropylene (PP), biaxially oriented polypropylene film (BOPF), polyethylene terephthalate (PET), cellulose triacetate (CTA). The films were kept in an acidic solution of potassium permanganate, washed, and the manganese content was determined. It was shown that according to the rate of deposition of manganese dioxide on the surface of the carrier, these materials are arranged in a row: CTA >> PE> BOPF> PET ≈ PP. It was found that the dependences of the specific content of manganese dioxide on the surface of polymer carriers were well approximated by straight lines (R2 = 0.964 - 0.997); the results of linear processing of the dependences were used to determine the deposition rates of manganese dioxide, ranging from 1.55 ± 0.26 μg/(cm2 day) for PP up to 166 ± 11 μg/(cm2 day) for CTA. It was shown that the high rate of deposition of manganese dioxide on the surface of the CTA in comparison with other polymer carriers was most likely due to the macroporous texture of the CTA surface. It was also shown that with a specific content of manganese dioxide of the order of 150-300 μg/cm2 achieved after 1-2 days of CTA treatment in a permanganate solution, a continuous uniform sorption-active layer was formed, and with a longer exposure time, an increase in the average layer thickness occurred due to the growth of individual crystallites already on the surface of a continuous layer of manganese dioxide, leading to a significant heterogeneity of the sorption-active surface, as well as to a stable deformation of the film. The sorption of 223Ra was studied on a series of obtained sorbents. It was shown that the amount of manganese dioxide phase in the composition of thin-layer sorbents had practically no effect on the sorption of radium from a salt-free solution, but strongly influenced sorption from 0.5 M NaCl. Also, for the MnO2-CTA sorbent the deterioration of the quality of the alpha spectrum due to the diffusion of radium deep into the sorbent was demonstrated. © 2021 Semenishchev V.S., Oglezneva V.Yu., Titova S.M.,Malyshev A.S., Filinkova V.K.Исследование выполнено при финансовой поддержке РФФИ в рамках научного проекта № 20-03-00931
