The Visegrad Group: is common policy towards Russia possible and necessary?

The article is devoted to the Visegrad Group that includes such “new” EU member - states, as Poland, Hungary, the Czech and Slovak Republics. The authors try to reveal a possibility of their consolidated policy towards Russia within the European Union. They come to a conclusion that, despite differences of interests, the common approach is possible in regard to Eastern dimension of ENP and especially on energy security matters, though it will not have a clearly binding characterye

Horizon Formation in High-Energy Particles Collision

We investigate a classical formation of a trapped surface in 4-dimensional flat space-time in a process of a non-head-on collision of two high-energy particles which are treated as Aichelburg-Sexl shock waves. From the condition of the horizon volume local maximality an equation for the trapped surface is deduced. Using a known solution on the shocks we find a time-dependent solution describing the trapped surface between the shocks. We analyze the horizon appearance and evolution. Obtained results may describe qualitatively the horizon formation in higher dimensional space-time.Comment: Latex2e, 8 pages, 6 figures, references adde

Features of Muscle Tissue Microstructure of Cattle in Industrial Agglomerations under the Environmental Pressure Conditions

The intensive development of the industrial sector, intensification of the agro-industrial complex, associated with the use of various fertilizers, active use of modern household chemicals lead to the constant increase in xenobiotics in the environment in both rural and urban agglomerations. There are settlements and farms within the industrial areas, therefore, the issue of accumulation of ecotoxicants in the organs and tissues of an animal, as well as the impact on the state of its health, is of particular importance. In the regions with tough environmental situation associated with anthropogenic contamination, xenobiotics of anthropogenic origin can directly or indirectly modify the activity of various body systems. The integral characteristic that reflects adaptive modifications of biota is the morphological and functional status of organs and tissues of an animal, including the state of muscle tissue. An analysis of the regenerative plastic potential of muscle tissue allows finding innovative approaches to assessing the effects of environmental impacts on animals. Up to the present day, the morphological and functional characteristics of muscle tissue in young animals and adult cattle have not been sufficiently studied in the conditions of the tough environmental situation of the Central Federal District of the Russian Federation. The issue of ecological pathologies of organs in productive animals is quite urgent for the territory of the Central Federal District with its developed agro-industrial complex and industry. The study of animals from the agglomeration of the large chemical plant showed that cattle react differently to pollutants. The animals demonstrated changes not only in hematological and biochemical parameters, but also in the morphological and functional status of muscle tissue

Digitalization of public administration in Russia: risks, casuses, problems

The article is devoted to the deliberation of the processes of digitalization of the activities of the authorities in modern conditions. The purpose of this article is to open a discussion on the problems of introducing new information and telecommunication technologies and improving the efficiency of the public administration system. Based on the analysis of the experience of implementing digital technologies and platform solutions in the field of public administration, a substantial characteristic of the problems of digitalization of public administration has been given. The key issues that require attention when carrying out digitalization of public administration on the basis of SWOT-analysis in terms of identifying weak, problematic aspects of the activities of the authorities and threats arising from the modern state of the Russian society, have been defined. Highlighting the weaknesses of modern public administration, the authors drew attention to such aspects of this problem as: 1) realization of “digitalization for the purpose of digitalization”; 2) deficiency of the required legal regulatory framework; 3) inefficiency of electronic document workflow, including problems caused by imperfections of the interface of reporting interactive forms, frequent change of the composition of indicators in reporting forms, desire of higher authorities to solve the problem of input of volume primary data at the expense of lower hierarchical levels; 4) absence of data analysis infrastructure, including due to imperfections of organization of interaction between agencies and incompatibility of information resources; 5) lack of data analysts and deficiency of necessary digital competences among state and municipal employees. Considering the threats and risks to the public administration system, the authors highlighted such aspects generated by the state of Russian society as: 1) creating a system of digital bureaucracy, 2) maintaining information and digital inequality, 3) insufficient knowledge and skills of citizens in the field of digital technologies, 4) reducing the publicity of the system of state and municipal administration. In the conclusion of the article it has been emphasized that the given facts are not unambiguously negatively interpreted, but it would be inexcusable to ignore even a small amount of them. It has been proposed to conduct a large-scale study that combines self-analysis of the processes of digitalization by authorities, a sociological study based on expert and mass surveys, an Internet survey

Three-dimensional distribution of the magnetic field and the flux in locally magnetized two-layer ferromagnetic objects

Numerical simulation of the spatial distribution of the magnetic field and the flux in two-layer objects is executed. The possibility of measuring the depth of a highly coercive layer on a soft magnetic core by the magnetic field measured on the surface of the object in the interpolar space of a U-shaped electromagnet is theoretically and experimentally shown. © 2016 Author(s)

The Digitalization Influence on the Transformation of Public Administration Methodology

The article shows that the ongoing processes of networkization, digitalization and hybridization lead to the creation of such a sociotechnical phenomenon as information and analytical platforms, which actualize a new type of social network relations between authorities and citizens in the public space of communications. In these conditions, a new methodology of public administration is required, which would take into account the digital realities of the modern world. According to the authors, the new concept of public administration should be built taking into account the development of a methodology for the following mutually conditioned processes: 1) creation of information and analytical platforms of the digital society; 2) formation of social structures in the network space; 3) configuration of relational networks for solving socially significant problems. It should be based on the actor-network concept and the digitalization ethics, the social network analysis, the relational sociology, the concept of figuration, the fractal-evolutionary concept, the concept of configuring a relational network of stakeholders

Hardware-software system for magnetic analysis of structure

The relative values of the magnetic properties of a substance is shown to be determined locally by measuring the magnetic field induction in the transducer hole of a special form made in the magnetic circuit of the measuring transducer and the tangential component of the magnetic field in the interpolar transducer space near the surface of the magnetized object.The proposed method is shown to allow for the determination of the whole complex of hysteresis characteristics and significantly expand the ranges of measurement of magnetic properties.The difference in the structural sensitivity of the magnetic properties locally determined in the coordinates "flow-internal field" (properties of matter) and in the coordinates "flow in the product-current in the windings" (properties of the "body") is established.The possibility and expediency of simultaneous measurement and pooled analysis of the magnetic characteristics of the substance and the "body" is shown.Information about the mobile hardware-software system DIUS-1.15M, designed to implement one-and multi-parameter methods of monitoring the structural-phase and stress-strain state of ferromagnetic materials and objects based on the proposed measurement techniques is provided. © Published under licence by IOP Publishing Ltd.Ministry of Science and Higher Education of the Russian Federation: АААА-А18-118020690196-3Russian Academy of Sciences, RAS: 18-10-2-8The research was carried out within the state assignment of Ministry of Science and Higher Education of the Russian Federation (theme “Diagnostics” No. АААА-А18-118020690196-3), supported in part by complex program of Ural Branch of RAS (project No. 18-10-2-8

The formation of colostral immunity and its duration in calves during the first months of life

The paper presents the results of a study on the formation of colostral immunity and the determination of its duration during the first months of life of calves according to the indications of the level of total IgG and antigen-specific antibodies to pathogens of рarainfluenza 3, respiratory syncytial infection and viral diarrhea of cattle. It has been established that blood serum of newborn calves does not contain antigen-specific immunoglobulins of class G to pathogens of viral diarrhea, respiratory syncytial infection and parainfluenza-3, and the level of total IgG is 2.2 ± 0.61 g/dm3. The concentration of total IgG is increased to 50.50 ± 6.33 g/dm3, and decreases to 27.25 ± 5.82 g/dm3 for 28 days, which contributes to the formation of the immunosuppressive state at the 7th day of a calf life. Starting from 35th day, there is an increase in the concentration of total IgG due to seroconverting of its own antibodies by the body of calves. Immunization of cows-mothers against viral diarrhea, respiratory syncytial infection and parainfluenza-3 contributes to the formation of antigen-specific colostral immunity in calves in the first days of life, which is preserved in diagnostic titers during 63 days after birth
