Supranational transfer of digital innovation in agribusiness through payment market mechanisms
Authors: Korobeynikova Olga , Korobeynikov Dmitry , Popova Larisa , Gorbacheva Anna , Likholetov Evgeniy
Published: May 2020

The task of creating a single supranational payment market is to ensure its maximum independence, which correlates with the tasks of the competitive leading economic development of countries - the transition to a digital technological structure. To increase the efficiency of the generation of payment innovations with their subsequent diffusion into the agricultural sector, to strengthen the economy’s resistance to risks, a transfer of innovative institutional, organizational and informational forms of activity is necessary. The strategy of integration of payment markets of interstate economic associations in time and space should be based on the consolidation and symbiosis of innovative technology platforms of sovereign payment systems of the participating countries. For this, a conceptual model of a supranational transfer of digital innovations to the agricultural sector through the transmission mechanisms of payment systems is proposed. The model characterizes the mega-economic system, which provides for the heterarchical and hierarchical interaction of payment systems of donor countries and recipient countries in the framework of economic associations, in which the transfer of forms of innovative development to the agricultural sector is carried out. Digital innovations are transferred to the subjects of the agricultural market horizontally and vertically. The transfer of digital innovation occurs through institutional, organizational and informational communications with the parallel creation of structures for the subsequent evolution of the model.

Published: May 2020

Management accounting of an economic entity in the agricultural sector is a complex multidimensional system. Sustainable development of the subject of business in the agro-industrial complex depends on many heterogeneous factors and conditions, which are understood as the reasons (driving forces) of any process determining its character or its separate features. The order of making decisions depends on the functioning of management accounting. In the context of diversity and heterogeneity of factors, a high degree of their uncertainty, complexity of interactions, study of these factors is a serious problem. Therefore, management personnel should carry out a constant analysis of all factors affecting the enterprise and assess their interaction, which reflects the cause-and-effect relations that characterize the sustainable development of the agro-industrial complex. The aim of the article is the justification of theoretical provisions and the development of practical recommendations for the development of analytical support of management accounting in the management of sustainable development of agricultural organizations. Objectives of the research: to study theoretical aspects and methodological tools, to determine the set of factors of sustainable development of a business entity, to develop absolute and relative indicators, which should be applied in management accounting for assessment and analysis of economic, social and environmental sustainability.

Authors: Beliakov Sergei , Shabanov Shakhin
Published: May 2020

The article is devoted to the consideration of theoretical issues and methodology for building an effective investment policy of an enterprise, taking into account that for enterprises operating in most fundamental sectors of the economy, including construction, oil and gas, transport, industrial production, etc., an important aspect that requires consideration in the development of investment policy is the impact on the environment. Environmental aspects impose restrictions on the choice of investment directions, applied methods and technical and economic indicators of projects and determine the potential competitive advantages of projects, including through the use of forms of state support. Environmental aspects of investment activity should be considered not only as basic constraints in the development of project solutions, but also as one of the factors of the enterprise’s competitiveness, which significantly affects its investment potential in the medium and long term. The authors also present a system of key principles for the formation of an enterprise’s investment policy taking into account environmental aspects and form a schematic diagram for the development of an enterprise’s investment policy taking into account environmental aspects. The use of the proposed methodological tools will help to increase the stability and efficiency of both the internal environment of the enterprise and its external environment, that is, the socio-economic system in which it operates.

Authors: Vasilyeva Elena , Krupnov Yuri
Published: May 2020

Industries are able to have the considerable impact on the environment. In this regard in modern conditions, when environmental friendliness is so relevant, the considerable attention is paid to the innovative development of the industrial enterprises. But investments into innovations in turn demand the careful analysis of the innovative projects. According to the authors, the methods, widespread in practice of the investment projects assessment can be used for the assessment of innovative projects in industries, but they need some adaptation. Besides, the majority of techniques of assessment consider only separate criteria of the selection of projects for realization. But the specifics of innovative projects demand another approach; they demand a complex research of appeal of the innovative project, including not only financial performance, but also technical quality, environmental safety, economic and budgetary effectiveness, social effect, risk analysis and also the analysis of reliability and appeal of the enterprise, initiating the project. Thus, the purpose of this article was to present the algorithm of the complex analysis of the innovative project. The received results and the made recommendations can be used by potential investors as a technique of assessment of the investment attractiveness of the innovation projects in the industry.

Authors: Pham Minh Tuyen , Bui Nguyen Khanh , Puzirevsky Roman
Published: May 2020

After 30 years of economic reforms since the launch of Đổi Mới in 1986, Vietnam has recorded significant and historic achievements. From a poor, war-ravaged, centrally planned economy, which was closed off from much of the outside world, Vietnam has become a middle-income country with a dynamic market economy that is deeply integrated into the global economy. But growth has to a large extent come at the cost of the environment. Vietnam’s greenhouse gas emissions have grown the fastest in the region, while the environmental quality of its air, land, and water has deteriorated considerably. Water and air pollution have reached serious levels, especially near Hanoi and Ho Chi Minh City, posing major health risks. As the most important environmental management tool, Environmental Impact Assessment (EIA) is recognized by Vietnamese Government and international organizations in the management of the impacts of future development on the country’s natural resource base. EIA is the important Chapter of Law on environmental protection 2014 of Vietnam (which was passed by the 13 National Assembly at the 7th session on June 23, 2014). This article argue that while significant improvements have been achieved in the EIA legal framework, the challenges remains between the EIA regulations and practice. This article contend that the current EIA legal framework is poor and facing with challenges and that future developments of the EIA regulations in Vietnam should focus not only on legislative documents but also on improving capacity of EIA practitioners with strictly sanctions.

Authors: Bui Nguyen Khanh , Nguyen Thanh Ly , Phan Khanh Duong , Nguyen Anh Thu
Published: May 2020

In recent years, the environmental pollution caused by a large amount of domestic solid waste generated in localities across the country is a challenge that governments of all levels, sectors and localities need to focus on solving. In order to make a substantial change in the domestic solid waste management, improve environmental quality and contribute to improving the quality of people’s lives, the Vietnamese Goverment is actively implementing specific activities to strengthen the management and recycle of domestic solid waste throughout the country. Besides, in the current legal documents, there is still a lack of guidance on appropriate technology selection and technical guidance on domestic solid waste collection, storage, treatment and recycle. Solid waste recycling activities are still scattered, spontaneous and lack the management and control of the competent authorities on environmental protection in the locality. The majority of recycling facilities are small in scale, the level of technology investment is not high, the majority of technologies are outdated and the machinery and equipment are obsolete, which causes environmental pollution. This article focuses on the challenges of recycling domestic solid waste in Vietnam. It also provides causes and recommendation to amend and supplement regulations related to recycling domestic solid waste in Vietnam

Authors: Zamorev Anton , Fedyukovsky Alexander
Published: May 2020

The paper is devoted to two ancient legal cases which, to date, have had no uniform solution: The Euathlus paradox and The Crocodile paradox. The aim of this work is not only searching logically faultless solution of both problems, but also developing the general approach to solving any similar cases without involving principles other than formal logic and the primary contract between litigants. The central problem of the research is that of incompleteness of this problem provisions, resulting in a set of various treatments the same questions. In the paper the following problems are solved: four exhaustive approaches to the problem of legal cases, which are called formal, authoritative, liberal and dialectic, are specified; the solution of the Euathlus paradox, which is inevitable with all the four approaches in the condition of their consistent application, is obtained; the solution of the Crocodile paradox, which is true with the dialectic approach, but impossible with three others, is obtained; it is proved that the dialectic approach not only combines the advantages of the first three approaches, but it is without their disadvantages that makes it a unique worthy applicant for the role of the universal approach.

Published: May 2020

The article discusses features of legal regulation of these legal relations, analyzes judicial practice. The leading research approach includes such scientific methods as dialectics, analysis, synthesis, and deduction, comparative legal and formal legal methods. The authors conclude that termination of severance pay stipulated by the agreement on termination of the employment contract does not indicate its illegality. The employee must be guaranteed the right to receive financial support for the period of job search, as well as the fulfillment of a voluntary obligation by the employer. The absence of acts providing for compensation payments in the organization is not a reason for refusing to pay severance pay. The conclusion of an agreement on termination of an employment contract has several advantages, provided that the obligations undertaken by the parties are met in good faith.

Using multi-criteria analysis to select an energy source
Authors: Koltun Oleg , Malykha Galina , Pavlov Alexander
Published: May 2020

Multi-criteria analysis is widely used to solve various technical and economic problems. There are a large number of applications of multi-criteria analysis. Methods for evaluating the total set of criteria have been investigated. However, the selection of criteria for various specific tasks remains the prerogative of specialists in the relevant branches. The goal of this study was to implement a multi-criteria analysis for assessing the potential of renewable energy sources' competitiveness. Renewable energy sources also include a closed nuclear fuel cycle based on fast-neutron reactors. The advantage of such cycle is the reproduction of nuclear fuel in the same or even greater quantity than it was used. At the same time, uranium isotopes are involved in the cycle, which are waste in conventional nuclear generation. The disadvantage of a nuclear fuel cycle is an output of hazardous waste and a complex technology for its processing. This task is a strategic one, and economic reason is not sufficient in this case. A structure of criteria for strategic decision making was compiled, and eight groups of main criteria were created. An expert analysis of the criteria was carried out and their relative significance was determined. Results. The significance of economic, environmental, technological and safety criteria is revealed. The formulae for criteria normalizing to apply the integration were proposed. Preliminary multi-criteria analysis has shown that a closed nuclear fuel cycle can compete with renewable energy sources such as wind and solar power plants.

Authors: Zhukov Vladislav , Zhukova Lyubov , Ponomareva Ksenia
Published: May 2020

The study is devoted to the development of technology to enhance the aesthetic characteristics of design objects made of chalcedony. These techniques can be applied to stone figurines and jewelry. An algorithm for designing products based on the properties and processing technologies of stone material is proposed. The surface decoration of a product made of chalcedony consists in the possibility of changing color, drawing a pattern and adding a texture. Two methods for changing the color of chalcedony have been studied - heat treatment and impregnation. The essence of the method of impregnation is the holding of the stone in a coloring solution at a temperature of 90 °C for 170 hours. The heat treatment method consists in processing chalcedony at a temperature of 350 °C, the duration of the temperature exposure is in the range of 5 to 20 hours. When dyeing samples of gray chalcedony, a color spectrum is obtained in the range of wavelengths from 582 to 590 nm. The formation of a smooth texture with various tools and materials of different grain sizes made it possible to obtain surface quality in the range of 1.1 - 0.02 microns. The technologies of drawing a pattern on the surface of chalcedony are revealed: etching, laser processing and local dye impregnation. When applying laser processing and etching, a white rough pattern is formed. Using local impregnation allows creating a color pattern on the surface of chalcedony. Results. The use and combination of the described technologies for decorating chalcedony allows creating the desired aesthetic characteristics of lapidary works of art.

Authors: Mirsaidov Mirziyod , Safarov Ismoil , Teshaev Mukhsin
Published: May 2020

In this paper the results of a study of the dynamic characteristics of thin-walled composite curved viscoelastic pipes under the influence of internal pulsating pressures is presented. The relationship between stress and strain is described by the Aviary equations. Based on the principle of calculus of variations, the equations of the dynamics of curvilinear shells are obtained. The obtained integral and integro-differential equations are solved using the finite element method, the Mueller and Gauss methods. The results of calculations of the natural frequencies of the shell and the curved rod are compared. As a result of the calculation, it was found that, shell vibrations occur at higher frequencies than rod vibrations (manifestation of a boundary effect). With this difference, the natural frequency, which has no analogue in the rod model decreases. This is due to the fact that, in this case the transverse vibrations of the section itself become significant, the rod. Some mechanical effects were discovered when taking into account the rheological properties of the pipe material.

Authors: Bessonov Igor , Zhukov Aleksey , Shokodko Ekaterina , Chernov Aleksandr
Published: May 2020

The article presents the results of a study of the state of production of a foam glass and the nomencla-ture of its products. It is shown that it is expedient to use the recycled glass obtained from the bottle battle, the defective glass and the double-glazed windows as a raw material for the production of the foam-glass. The re-quirements are formulated for glasses, which should have low viscosity values in the range of foaming tempera-tures. The features of the technology for the production of the foam glass aggregate at the specialized lines are outlined. The technology features are the composition of the charge and temperature conditions of burning. The mixture for the production of the foam glass aggregate consists of glass flour, organomineral blowing agent con-taining water and food glycerin, as distinct from the slab foam glass, where soot or coke is used as a blowing agent. The results confirm the effectiveness of the use of the foam glass aggregate as a soundproofing backfill for floors. Currently, about 70% of the foam glass aggregate is used for roofs and stylobates; the rest is used in landscape design, road construction, foundations and major repair. In the future, the areas of application of the foam glass aggregate can be significantly expanded in the direction of building systems, lightweight aggregates, etc., which involves in-depth studies of the properties of this material.

This paper reviews the issue of selecting the compositions of ceramic masses for the production of ceramic blocks made out of technogenic raw materials of a coal series using the methods of mathematical planning. The possibility of replacing classic clay raw materials with non-traditional coal technogenic raw materials (screenings of heaps), which are formed during the processing of heaps with the aim of extracting coal, is considered. The reasons for the growing interest in this technogenic raw material were the reduction of the base of high-quality clay raw materials, the large number of accumulated heaps, as well as the need to reduce the cost of production of ceramic blocks.

The Fukushima-Daiichi accidents in 2011 underlined the importance of severe accident management (SAM), including external events, in nuclear power plants (NPP) and the need of implementing efficient mitigation strategies. To this end, the Euratom work programmes for 2012 and 2013 was focused on nuclear safety, in particular on the management of a possible severe accident at the European level. Relying upon the outcomes of the successful Euratom SARNET and SARNET2 projects, new projects were launched addressing the highest priority issues, aimed at reducing the uncertainties still affecting the main phenomena. Among them, PASSAM and IVMR project led by IRSN, ALISA and SAFEST projects led by KIT, CESAM led by GRS and sCO2-HeRO lead by the University of Duisburg-Essen. The aim of the present paper is to give an overview on the main outcomes of these projects.

The 7th EU Framework programme project Advanced Safety Assessment Methodologies: “Extended PSA” (ASAMPSA_E, 2013–2016) was aimed at promoting good practices to extend the scope of existing Probabilistic Safety Assessments (PSAs) and the application of such “extended PSA” in decision-making in the European context. This project led to a collection of guidance reports that describe existing practices and identify their limits. Moreover, it allowed identifying some idea for further research in the framework of collaborative activities. The H2020 project “New Approach to Reactor Safety ImprovementS” (NARSIS, 2017–2021) aims at proposing some improvements to be integrated in existing PSA procedures for NPPs, considering single, cascade and combined external natural hazards (earthquakes, flooding, extreme weather, tsunamis). The project will lead to the release of various tools together with recommendations and guidelines for use in nuclear safety assessment, including a Bayesian-based multi-risk framework able to account for causes and consequences of technical, social/organizational and human aspects and a supporting Severe Accident Management decision-making tool for demonstration purposes, as well.

The European Atomic Energy Community (Euratom) Research and Training framework programmes are benefitting from a consistent success in pursuing excellence in research and facilitating Pan European collaborative efforts across a broad range of nuclear science and technologies, nuclear fission and radiation protection. To fulfil Euratom R&D programmes key objectives of maintaining high levels of nuclear knowledge and building a more dynamic and competitive European industry, promotion of Pan-European mobility of researchers are implemented by co-financing transnational access to research infrastructures and joint research activities through Research and Innovation and Coordination and Support Actions' funding schemes. Establishment by the research community of European technology platforms are being capitalised. Mapping of research infrastructures and E&T capabilities is allowing a closer cooperation within the European Union and beyond, benefiting from multilateral international agreements and from closer cooperation between Euratom, OECD/NEA, IAEA and international fora. ‘Euratom success stories' in facilitating Pan-European E&T collaborative efforts through Research and Training framework programmes show the benefits of research efforts in key fields, of building an effective ‘critical mass’ and implementing European MSc curricula, of promoting the creation of ‘Centre of Excellence’ with an increased support for ‘Open access to key research infrastructures’, exploitation of research results, management of knowledge, dissemination and sharing of learning outcomes.

We present a cross-cutting review of three on-going Horizon 2020 projects (ADVISE, NOMAD, TEAM CABLES) and one already finished FP7 project (HARMONICS), which address the reliability of safety-relevant components and systems in nuclear power plants, with a scope ranging from the pressure vessel and primary loop to safety-critical software systems and electrical cables. The paper discusses scientific challenges faced in the beginning and achievements made throughout the projects, including the industrial impact and lessons learned. Two particular aspects highlighted concern the way the projects sought contact with end users, and the balance between industrial and academic partners. The paper concludes with an outlook on follow-up issues related to the long term operation of nuclear power plants.
