Specific features of state regulation of operations with cryptocurrencies in the conditions of digitalization

Purpose: The article investigates specific features of state regulation of operations with cryptocurrencies in the conditions of the world economy digitalization. Design/Methodology/Approach: In order to form the state regulation of operations with cryptocurrencies, which create additional risks for the national currencies functioning in international financial and credit relations, it is necessary to consider this phenomenon first, from the position of a complete ban on the use of cryptocurrencies as a means of payment, second, in combination of a ban on the use of cryptocurrencies as means of payment, third, from the possibility of expanding the range of cryptocurrency users by including legal entities into it and fourth, the full legalization of the cryptocurrency. Findings: The authors developed and proposed a set of measures aimed at the formation of common standards and norms of state regulation of operations with cryptocurrencies in international financial relations. Practical Implications: The results of the study can be applied in the development of legal regulation of virtual currencies not only at the national level, but also at the international level. Originality/Value: The main contribution of the study is to identify possible risks in the sphere of state regulation of cryptocurrencies based on the experience of some countries: from formal permission (including recommendations on possible risks) or the application of general principles of regulation in the field of payments to the complete ban of such activities.peer-reviewe

The role of crypto-currencies in the development of the global currency system

The world monetary system is in the process of transition to a new level of development under the influence of the process of financial globalization, economic integration, as well as the activation of electronic currencies turnover. In these conditions, it is necessary to understand the causes of the changes and their possible consequences. One of the possible options for the development of the world monetary system can be the use of crypto-currency as international money.peer-reviewe

Applying Principles of Multi-Factor Genetic Analysis of Infectious Disease Agents in the Work of the Rospotrebnadzor SAET during Mass Events

Objective of the study – to develop and test in operation of the Rospotrebnadzor Spesialized Anti-Epidemic Teams (SAET), deployed during the major mass events, the procedure for application of molecular-genetic methods for detection and identification of pathogenic biological agents. Materials and methods. Utilized are the reporting documentation drawn up by the results of work of the specialized anti-epidemic teams of the Rospotrebnadzor on the provision of sanitary epidemiological welfare during Olympic Games 2014 and other important mass events in Sochi in 2015–2017. Results and conclusions. Developed and tested in practice of the Rospotrebnadzor SAET during the major mass events has been procedure for application of molecular-genetic methods, based on structured approach (algorithm) of indication and genetic characterization of PBA. Equipping of the SAET with diagnostic preparations is carried out in accordance with the provision of preparedness for performing investigations by three-level algorithm of molecular-genetic characteristics of pathogens: level I – detection (indication) of a pathogen using PCR, level II – identification of the pathogen genome fragments using PCR, level III – genotyping. Developed procedure was used successfully by the SAET during the Olympic Games 2014 and other important mass events in Sochi in 2015–2017, which allows for recommending it for future use

Search for Free Decay of Negative Pions in Water and Light Materials

We report on a search for the free decay component of pi- stopped in water and light materials. A non-zero value of this would be an indication of anomalous nu_e contamination to the nu_e and nu_mu_bar production at stopped-pion neutrino facilities. No free decay component of pi- was observed in water, Beryllium, and Aluminum, for which upper limits were established at 8.2E-4, 3.2E-3, and 7.7E-3, respectively

Studies of Genetic Diversity of Yersinia pestis Strains Isolated in Central-Caucasian High-Mountain Natural Plague Focus

Studied have been Yersinia pestis strains isolated in Central-Caucasian high-mountain natural plague focus within the period of 1971–2012 using MLVA typing on 25 VNTR-loci. Analysis of dendrogram cluster association with certain areas, objects, and periods of the strain isolation has been carried out by means of Arc GIS 10.1 software. Established has been the connection between 25 MLVA Y. pestis types and spatial and temporal characteristics of strains isolation in the Central-Caucasian high-mountain natural plague focus, and proline requirement too. Clusters, groups and subgroups of the strains are confined to particular territories as it follows: groups are attributed to landscape-epizootiological regions, subgroups – to mountain souslik settlements. Occasionally groups of the strains disseminate onto the other landscape-epizootiological regions of the focus. Genetic variations of plague agent strains within the limits of mountain souslik settlements evolve over time which can be viewed as indirect evidence of microevolution mechanism effect
