Tools for estimating the effectiveness of import-substituting modernization : sase in the agriculture of Russia

The paper explores the approaches to estimate the effectiveness of import substitution, justifies the need to develop a new tool that allows conducting a comprehensive analysis of the impact of import substitution policies on economic modernization. The authors‘ methodology for estimating import-substituting modernization based on an integral indicator is proposed and its practical approval is carried out using agriculture in Russia as an example. The analysis of the results allows the authors to conclude that the import-substituting modernization process is uneven and slow. To activate and accelerate the processes, it is necessary to stimulate domestic demand. The developed tools react quite sensitively to changes in the industry and make it possible to identify cause-effect relationships in a structured factorial analysis of processes.peer-reviewe

Adaptation of market strategies of TNCs in Russia in the context of import substitution policy

The policy of import substitution carried out in Russia objectively affected the interests of leading transnational corporations (TNCs) operating in the Russian markets. The restriction of imports of intermediate goods and the fall in the purchasing power of Russian consumers have formed for TNCs both new problems and new opportunities. The analysis of the integration of TNCs in the Russian policy of import substitution is carried out in the article; their role in the development of industries and agriculture is revealed. It is revealed that the strategies of TNCs are characterized by great flexibility, which allowed them to reduce the negative impact of sanctions and geopolitical tensions. TNCs widely use the strategy of acquisition of popular Russian brands. The weakening ruble and the cheapening of labor costs became additional decision-making factors for the localization of production and selection of local suppliers of intermediate goods, investing in modernization of production facilities, the establishment of added value chains with the involvement of national producers that contributed to the successful embedding of TNCs in the policy of import substitution.peer-reviewe

Electrochemical Reducing of Terbium and Holmium Ions in the Sodium and Potassium Chlorides Melt with Equimolar Composition

Interest to rare-earth metals (REM) and their alloys is due to the possibility of using them for the creation of new materials need for modern technology. For instance, REM as alloying components allows for preparation of material with special magnetic properties. A promising method for forming such coating is the surface treatment of metals. This process has an electrochemical character as such for the organization of technology the knowledge of kinetics and mechanism of these processes is important. Despite significant interest in rare-earth metals, these issues are not well described in the literature. In order to choose an adequate mathematical model for calculation of kinetic primers, preliminary experiments that allow evaluating the reversibility of the electrode process have been conducted. Based on that, it was concluded that cathodic reduction of terbium and holmium ions in equimolar NaCl-KCl melt is irreversible. By means of voltammetric analysis, kinetic parameters (transfer coefficients, heterogeneous constants of charge transfer rate) of terbium and holmium electroreduction in equimolar NaCl-KCl melt were determined. The experiment was conducted in a three-electrode cell under a purified argon atmosphere. A dependency of kinetic parameters on the concentration of terbium and holmium chlorides wt (%): 1, 3, 5, 7, 10, was determined. The experiment was conducted in 1073–1173K temperature range. Values of kinetic parameters increase with temperature but decrease with the increase of REM chloride. Based on obtained data, it was found that electroreduction of chloride complexes LnCl63– (Ln–Tb, Ho) in equimolar NaCl-KCl melt is irreversible in the studied range of temperatures and REM concentrations. In summary of experimental data, in range of temperature and rare-earth chloride concentration, and assumption was made that reduction of terbium and holmium ions occurs in two stages. The process includes the preceding stage of complex dissociation. A mechanism of LnCl63– complex reduction in the mentioned melt is proposed. The obtained results are in agreement with literate data for analogues systems

Determination Of Formation Regimes For Bilayer Cobalt Dysprosium Intermetalic Surface Alloy

High tech industrial fields on modern development stage are in need of construction materials with an optimal ratio of volume and surface properties, along with low cost of material itself. As evidenced by studies, in order to give a set complex of properties to a workpiece that operates under specific conditions, it is often sufficient to only modify its surface area. Over the course of studies, by means of gravimetric, influence of technological parameters (temperature and time samples are kept in the melt) on specific mass change of cobalt samples, that act as substrate, during electroless diffusive saturation with dysprosium in eutectic melt of lithium and potassium chlorides have been studied. A mathematical dependency was established for specific mass change of cobalt samples on time spent in melt for temperature range of 873–973 K. Composition of intermetallic coats obtained on surface of cobalt samples was studied means of EDX and SEM analyses. It was discovered, that for chosen temperature range, diffusion layers formed on surface of cobalt samples consists of two structural zones that correspond to Co-Dy and Cp2Dy phases

INTERACTIVE PROMOTION INSTRUMENTS AS A TREND IN RETAIL COMMUNICATIONS SOLUTIONS

This article reviews the usage of interactive instruments that become a developing trend in modern retail sector. In the last few years more retail companies start to integrate interactive format of communications in real business practice. Interactive marketing communications allow narrow targeting for the audience which helps to attract attention to the specific retail segment, improve customer loyalty and economic wealth of the company. That type of communications has all sorts of expected advantages that are focused to: attract customer attention, stimulate call to action, generate positive brand image, inform and educate the customer

Определение расходных характеристик в технологических процессах с контролируемым давлением

Assessment of the environmental and economic performance of a safety valve requires information about the flow of the substance through the valve when it is actuated. The goal of this paper was to determine the flow rate of the discharged substance and the mass flow rate of the substance entering the safety valve when it is actuated. Proposed a mathematical model to describe the processes occurring in the valve. The model includes a system of differential equations describing the physical laws of conservation in the internal volume of the valve and differential equations, which link the value of gas flow through the valve with the pressure and the amount of movement of the shut-off disk. Used a modified method by S.K. Godunov to solve gasdynamic equations. Established that the determination of the flow and power characteristics of the valve requires the preliminary construction of a mathematical model of the safety valve operation. Based on this, proposed a method for determining the flow rate of the discharged substance and the mass rate of the substance entering the safety valve when it is actuated. Obtained the flow characteristics of the valves under review and the dynamics of movement of the shutoff disc of the valve, as well as the dependence of the pressure change on the opening time of the valve. Comparison of the calculated values with available experimental data gives good agreement of results (no more than 5.6 % for a gas flow rate, under 10 % for the movement of the valve and change the arrival of gas in time using the standard deviation function of the flow characteristics of 0.6 %), confirms the correctness of the defined mathematical model, used numerical schemes and algorithms, as well as the proposed method and recoverability of the arrival of gas in a pressure–time curve
