Im Zuge der Verstaatlichung des Bodens nach der Revolution wurden die privaten Eigentumsverhältnisse an Grund und Boden aufgehoben. Die Zwangskollektivierung, Konzentration und Großproduktion sind nicht allein auf theoretische Fehler zurückzuführen, die Gründung von Kollektiv- und Sowjetgroßwirtschaften entsprach den Bedürfnissen der zentralisierten Befehlswirtschaft: je größer die Wirtschaften, desto einfacher die Leitung. Der Autor zeigt die Uneffektivität solcher Organisationsformen der Agrarproduktion auf. Beim Übergang zum Markt ist es unumgänglich, das Monopol des Staatseigentums abzubauen. Hierzu bieten sich folgende Möglichkeiten: Durchsetzung der Pacht, Umgestaltung der Kolchose und Sowchose in Aktiengesellschaften, agroindustrielle Diversifikation der Produktion, Entwicklung von Farmwirtschaften.

The aim of the study is to propose and substantiate recommendations for development of the export potential of the Russian agro-industrial complex (AIC) in the Eurasian Economic Union (EAEU). The paper assesses the benefits of the Russian agro-industrial complex within the EAEU and measures to extract them for exporters. It develops recommended measures of state support that promote development of the Russian agro-industrial complex under EAEU membership conditions. The author considers state regulation measures for the following sectors of the Russian agro-industrial complex: agriculture, food industry, agricultural machinery, and fertilizer production. The author makes the following conclusions in the work. Russia exports to the EAEU products that are less in demand on other external markets. Overall, Russia's trade relations with the EAEU countries are as follows: 1) companies in the agrochemical and food industries are in a winning position; 2) a relatively positive effect is observed in the agricultural machine building industry; 3) a relatively negative impact is observed in the dairy industry and production of meat products (due to competitive pressure from Belarusian producers). To improve the competitiveness of Russian products, as well as to identify their niche in the EAEU market, enterprises should be assisted in finding new markets and developing cooperation. The diversification of export-oriented production, which has already established itself in the external market, can be used to consolidate markets on the territory of the EAEU to sell goods. Here, the capacities created to assist subjects of industrial-innovation activity and production of innovative goods (for example, in agricultural robotics) should be attracted.

Abstract. This paper presents the algorithms and results of the numerical simulation of the solution of a 2-D inverse problem on the restoration of seismic parameters and electrical conductivity of local inhomogeneities by the diffraction tomography method based upon the first order Born approximation. The direct problems for the Lame and Maxwell equations are solved by the finite difference method. Restoration of inhomogeneities which are not very weak is implemented with the use of a small number of receivers (source-receiver pairs).

Climate change and anthropogenic pollution have put limited water resources under pressure. Lack of basic sanitation services as well as the discharge of improperly treated effluent from wastewater treatment plants (WWTP) result in the deposition of large amounts of organic matter and nutrients, which have major detrimental effects on health. Wastewater treatment (WWT) can reduce water pollution but at the cost of increasing energy consumption and the corresponding atmosphere and climate problems. Sustainable WWT management is a global challenge to preserve fresh water and decrease energy consumption. Nowadays it becomes obvious that existing WWTP operation model, based on the linear "take-make-dispose" pattern, is no longer sustainable. Furthermore, disposal of a product in landfill means that all residual energy is lost. The adoption of circular economy (CE) practices with its 3R principles of reducing, reusing and recycling material appears as a timely, relevant and practical option to meet the goals of sustainable development. WWTP is a critical element in CE implementation policy and to measure the degree of "circularity" there is a need for indicators. This study considers the holistic overview of measuring the progress of CE implementation at WWTP under 3R principles using life cycle analysis (LCA) and material flow analysis (MFA) frameworks. The paper presents the principles of CE indicators set construction using managerial approach. The proposed set of indicators and integral circularity index are studied under three scenarios, based on real performance of northern and southern WWTP in Ekaterinburg, Russia. This study provides an efficient assessment tool of CE progress, which is rather simple for calculation and interpretation and suitable for the use of wide range of stakeholders. © 2019 WIT Press. ; № 02.A03.21.0006 ; This research was supported by Act 211 Government of the Russian Federation, contract № 02.A03.21.0006.

The article is devoted to the investigation of the nature of the increment in surface concentration of toxic gas sulfur dioxide (SO2) in Northern Finland. The study is carried out for June 2011 when the increased near-surface SO2 concentration was registered at Finnish observation station Inari Raja-Jooseppi together with the surface wind blowing from the territory of the Kola Peninsula. The hypothesis of natural increment of near-surface SO2 concentration as a result of Grímsvötn volcano eruption (Iceland) is verified using satellite SO2 observations by OMI, numerical weather prediction and atmospheric chemistry model Enviro-HIRLAM and particle dispersion model HYSPLIT. The results show that not only local man-made sources, but also the remote transfer of pollutants from volcanic eruptions can cause an increased near-surface SO2 concentration. To verify this hypothesis, a large set of statistics is required in Northern Finland during periods of volcanic activity in Iceland.
