Authors: Baldano Marina N. , Dyatlov Victor I. , Kirichenko Svetlana V.
Published: June 2020

The article focuses on diasporas and migration in the Mongolian world (both inside and outside its borders). There is a wealth of ethno-diasporal forms and mechanisms, unexpected and peculiar adaptation processes of migrants and host societies on this research field. The novelty lies in the attempt to compare the Buryat migrations to Mongolia, China and South Korea. The rich “line” of migration types from traditional migrations to modern educational and labour migration in a globalizing world makes the problem extremely urgent. The goal is the analysis of diasporal strategies (from the transplantation version of Shenekhen Buryats to modern cross-border Buryat migrants consolidating via the Internet) and a preliminary assessment of the characteristics of crossborder Buryat migration to South Korea. The study of ethnomigration processes makes it possible to consider the practices of adaptation of migrants to the host society, strategies for constructing migrant communities, the institutionalization processes of the Buryat diasporas associated with the creation of interaction mechanisms in host countries. The study takes into account the latest achievements of various sciences, at the junction of which it was carried out. Along with general historical approaches, methods of qualitative sociology were used: interviews, polls, discursive analysis of the media, and research on a set of official documents, statistics. The article consists of three case-studies and is based on an analysis of Russian, Mongolian, Korean official documents, media materials, a series of conversations and interviews obtained during field studies of the authors in Mongolia, China and South Korea

Published: June 2020

The article reflects the main features of the new Strategy for Socioeconomic Development of the Northern and Arctic Regions of the Krasnoyarsk Territory of Russia. The work employs standard methodological tools for the development of the regional strategic documents, such as assessment of the situation, general principles of the socioeconomic development of the Northern and Arctic regions, characteristics of the main tools and expected results of the strategy, and spatial planning issues. The new policy is aimed to soften development contrasts between the Northern and Arctic municipalities of Krasnoyarsk krai. Big expectations are associated with the introduction of innovations in the delivery of the critical services and products to the remote towns and settlements of the area. The main methodological innovation applied in the Strategy is the establishment of three project offices working on the problem on three large-scale levels. These are the “Person”, “Settlement” and “Territory” project offices. Their tasks involve ensuring synergy between the government, large and small businesses, and social bodies. It is assumed that in the year 2030 the implementation of the proposed measures will enable the Krasnoyarsk Territory to regain its leading position in the development of the Russian Arctic it used to hold during the first decades of the Soviet period
Overvoltage protection for grid-connected picohydro generation using photovoltaic inverters
Authors: Scotta Isabella Cristina , Silva Wellington Maidana , Leite Américo Vicente
Published: June 2020

Very small-scale hydropower plants are environmentally friendly and renewable resource-based innovative solutions. The interest in pico-hydro systems (up to 5 kW) has increased significantly from the first stand-alone applications, at remote sites, to the distributed generation, with the injection of generated energy into the grid. Recently, there have been advances in the grid connection of these systems using off-the-shelf components, namely photovoltaic inverters. Therefore, pico-hydro systems have gained an enormous potential in distributed generation, particularly in the context of microgrids. However, in situations of over-power, or whenever the generator is under no load, e.g. when the grid fails, there is a need for effective over-voltage protection, as in small wind turbines. This paper proposes two over-voltage protection circuits, designed to ensure the integration of pico-hydro turbines connected to the grid using conventional photovoltaic microinverters and string inverters, for power ranges of 300 W and some kW, respectively. Extensive tests were performed on an emulation platform and a workbench using these two different over-voltage protection circuits. One is designed to connect the generators of water wheels to the grid and the other to connect 1,500 W generators of water turbines. The experimental results demonstrated the performance of theproposed over-voltage protection circuits in four different situations. Both avoid irreversible damages of generators, photovoltaic microinverters and string inverters in the context of the above-described grid connection approach.

Published: June 2020

The current study was planned to evaluate the supplementation of Polyvinylpyrrolidone in extender on cryopreservation of Nili-Ravi buffalo bull semen. The semen samples were collected from Nili-Ravi buffalo (Bubalus bubalis) bull kept at SPU Qadirabad, District Sahiwal, Pakistan. Qualifying semen ejaculates having motility >60%, volume >5-6ml and concentration >0.5 billion/ ml were diluted 50 × 106 motile sperm ml approximately at 37°C in Tris-citric acid extender supplemented with different concentrations of PVP (0.01, 0.05, 0.1mM). The extender without PVP was kept as control. Semen was stored at 4°C for a period of 2 h and kept at 4°C for 4h. Semen was filled in 0.5 ml French straws using suction pump at 4°C, plunged and stored in liquid nitrogen (-196°C). Semen straws were rewarmed at 37°C for 30 seconds and assessed for sperm motility, plasma membrane integrity (PMI), dead sperm percentage and the live sperm percentage. The data on the role of PVP on different parameters of semen quality were analyzed by using ANOVA and RCBD. Higher percentage (P< 0.05) of sperm motility (66.1±7.51 and 59.4±10.72) and PMI (72.9±5.39 and 75.7±6.5) was observed in extenders having 0.05 mM and 0.1mM PVP compared to extenders having 1.5mM PVP and control. The percentage acrosomal integrity was observed greater (P< 0.05) in extended semen containing 0.1mM (68.2±0.50) PVP compared to extenders having 0.01 and control.
IDEOLOGICAL FUNDAMENTALS OF CONFLICT REGULATION IN EASTERN UKRAINE
Authors: Abyzova Larysa
Published: June 2020

The article researches ideological principles of conflict regulation, in particular, the conflict in Eastern Ukraine in the context of forming of national-state ideology. This indicates theoretical and practical interest to a certain topic, which gets new sense and sound at each stage of national and state existence. It has been found out that political strategies should enable planning and forecasting political processes, minimize political bias, and meet reform projects. It is noted that the main vector of socio-cultural transformations had been proclaimed to be the posttotalitarian, post-colonial vector that a priori should permanently protect the state from the disadvantages and tragedies of the previous political era. Philosophical reflection is aimed at understanding of one of the most important components of national-state ideologies – a national idea. At present, there is no single national-state ideology in Ukraine, since new forms of understanding of social reality are in the process of formation. Obviously, it will be formed in the context of political forces’ struggle and compromising. The crisis of unity in Ukrainian society is interpreted as a factor that does not contribute to the formation and implementation of a rational political strategy of the state. It is concluded that European spirit of Ukraine and national self-esteem should be formed on state level in internal and foreign politics, on theoretical level in the programs of state reforms, in the concepts and programs of education and upbringing, on daily life level in ideological regulations of interpersonal communication rules. It is concluded that there are the following steps towards peace, first, the cessation of hostilities and pressure, second, the establishment of dialogue, and third, the search for a solution to the contradictions through negotiations.
Objective classification of atmospheric processes for the East European region
Authors: Khokhlov V. , Umanska О. , Deriabina I.
Published: June 2020

The article describes the objective classification, involving the automated systems application to section the atmospheric processes by types. The objective of typing is to split a collection of objects of a certain sample according to the maximum-distance-separable groups. The basis for objective classification includes several methods: correlation, cluster analysis, nonlinear methods, neural network method, etc. One of the analysis methods for the characteristics of synoptic processes is typing, or the classification of synoptic processes by types, which allows finding common features of development of atmospheric processes in a large variety of synoptic situations. The objective of typing is to split a collection of objects of a certain sample by maximum-distance-separable groups. Since the beginning of the XIX century, when the classification of synoptic processes was introduced to the practice of weather forecasting, there were published a large number of works that differ in specific methodological approaches, in a number of selected types of weather, etc. Currently, only on the territory of Europe, according to various estimates, researchers allocate from 4 to 40 types of atmospheric processes and account for up to 209 subtypes, 84 % of which is obtained by analyzing the data of surface atmospheric pressure, geopotential heights and wind characteristics. On-scale data from 6 to 12 hours (9 %), daily (84 %) and monthly data(7 %) are used as an output information. The spatial range varies from mesoscale (5% of classifications), regional (3 %), on an individual nationwide scale (20 %), as part of the continent (22 %) and the continent as a whole (50 %) The second half of the XX century and the beginning of XXI century are characterized by high rates of changes in climatic and circulation conditions. An occurrence of rare weather extremums is a manifestation of the transition state of the atmosphere and its instability. Often regional changes have more significant variations than global. Therefore, progress, in the understanding of current trends of climate change, is impossible without taking into account spatiotemporal dynamics of atmospheric processes. The author considers the main principles of GWL classification and investigates regional characteristics of synoptic processes in the territory of Europe based on the characteristics of the surface baric field and displacement trajectories of the main baric systems. The purpose of this paper is to explore one of the most popular classifications for the European region and to establish the possibility of its further application to the territory of Ukraine. Research methods: a statistical description of the synoptic types for Europe for the period from September 1957 up to August 2002. Results of the study confirm the fact, that the addressed classification is aimed at creation of seasonal and interannual forecasts of synoptic processes and works better in the central, western and southern directions of Europe.
Navigating the “Bureaucratic Beast” in North Carolina Hurricane Recovery
Authors: Reinke Amanda J. , Eldridge Erin R.
Published: June 2020

Hurricane Florence swept up the eastern United States coast and slowly moved through North Carolina as a tropical storm in September 2018. Producing twenty to thirty inches of rain, Florence caused dangerous flooding, displacement, and widespread wind damage and power outages. While coastal areas were hard hit by the storm, many impoverished in-land areas spanning multiple river basins were also heavily flooded. Although the winds have ceased and the waters receded, the disaster continues to unfold in bureaucratic contexts with uneven effects temporally and spatially for affected locals. Local organizations and the Federal Emergency Management Agency assess damages, process funding applications, and work to rebuild. Drawing on ten months of ethnographic research in Cumberland County, NC, we illuminate the ways in which the temporality of bureaucratic processes is a form of bureaucratic violence that exacerbates suffering in the context of crisis and how local organizations attempt to recover and rebuild in the face of pervasive top-down bureaucratic obstacles.
The Emergence of the Village and the Transformation of Traditional Institutions: A Case Study from Northern Tanzania
Authors: McCabe J. Terrence , Leslie Paul W. , Davis Alicia
Published: June 2020

In this paper, we examine how the 2008–2009 drought in northern Tanzania contributed to and catalyzed the transformation of governance concerning the management of natural resources from traditional informal institutions among the Maasai to formal village-based institutions. Our central argument is that village governance in northern Tanzania represents a new, formal institution that is supplementing and in some important ways obviating traditional, informal institutions. Further, this replacement is central to what appears to be a transformation of the social-ecological system embracing the rangelands and pastoral/agro-pastoral people in northern Tanzania. In this paper, we document the basis for our claims concerning the institutional shift and discuss its implications for livelihoods and social relationships.

Authors: Kostenko Nikolai
Published: June 2020

The aim of the study is to develop the main approaches to providing states with international information security. The role of the Russian Federation and other states in advances in information and telecommunications within the framework of international security is being investigated. Attention is drawn to the rapid formation and use of information and communication technologies, which have made up a large and lasting dependence of adverse government mechanisms on real cyber technologies and has been the reason new threats.

The role of the Russian Federation in the purposeful work of shaping the United Nations doctrine on world information international security is being investigated. The UN General Assemblys Resolution A/RES/56/19, Advances in Information and Telecommunications in the Context of International Security adopted on 7 January 2002, endorsed the idea of researching current and possible threats to information security and drawing attention to the likely collective measures to eliminate them.

The Russian Federations proposal for education, the composition of government experts, which could concentrate and discuss the most important stages that aim the subjects of international law to participate in the UN General Assembly Resolution of December 8, 2003 No. 58/32 Achievements in the field of information and telecommunications in the context of international security are analyzed.

The article draws particular attention to the document of the UN General Assembly A/55/140 which outlined five principles on international information security. The article examines in detail the resolutions of the United Nations General Assembly Advances in Information and Telecommunications in the context of International Security from December 4, 1998 to October 22, 2018 to ensure international information security.

The novelty of the study is the conclusions and proposals on problematic issues in the field of international information security, which would contribute to the adoption of a single international UN Convention, which would contain a conceptual apparatus, objectives, objectives, types of threats, priorities and mechanisms for their implementation, as well as provisions on the responsibility of States in the international information space.
Ideological myths of European union on the example of Laeken declaration
Authors: Novoseltsev Alexey
Published: June 2020

The European Council adopted Laeken Declaration in which it was first stated about EU aspiration to take the lead on world globalization together with USA. The subject of this study is the analysis of myths and ideological cliches of Laeken Declaration by which EU and USA legitimize their foreign policy.

The author concludes that the future of EU was not as optimistic as stated in the text of the declaration. Until recently, the EU was a state in the process of formation, and its legal area acquired the features of a domestic order. These processes have slowed down now. An external challenge was the change in the format of relations with Russia, which openly declared its national interests and cooperation only as a equal partner. Previously unthinkable social problems appeared in the space of well-being.

The history of Russia teaches that going to Europe can be done in different ways. The path of european integration put the Russian state on the brink of complete disintegration of the late XXth century. The consequences of this choice are currently being overcome in the framework of Eurasian integration and integration with states outside the post-Soviet space that have common interests with Russia.
“Deal” in German criminal procedure
Authors: Rönnau Thomas
Published: June 2020

This article is a translation from German of the original and crucial material published by the doctor of law, professor Thomas Rnnau in the journal JuS in 2018 (Thomas Rnnau. Grundwissen Strafprozessrecht: Verstndigung im Strafverfahren // JuS. 2018. № 2. S. 114-118). The article written by prof. T. Rnnau is devoted to the analysis of the institution of agreement in German criminal procedure (admission of guilt). On the one hand, the criminal justice system at the present stage faces a real need to use a simplified form of criminal proceedings, which allows us to solve the problem of procedural economy. On the other hand, the number of cases resolved in a special (simplified) order in the past few years has become so large so such the cases instead to be "special" passes into the category of ordinary (not special). Today, "Deal" justice in criminal cases is characteristic of the criminal process of many foreign countries, including Germany. Translation of the article by Prof. T. Rnnau will allow the readers to see theoretical and practical problems faced by the German legal doctrine and a practitioner in connection with the institution of agreement (admission of guilt) in criminal procedure. Prof. T. Rnnau offers a solution to the problems he outlined.
Problems of understanding the sale of narcotic drugs in doctrine and judicial practice
Authors: Shevchenko Evgeniy
Published: June 2020

In the article the problems of judicial and academic interpretation of the concept of sale of narcotic means and psychotropic substances. Currently, essential questions of understanding of marketing in order to distinguishing this transaction from other types of physical transfer of the drug to others, do not accept the sale, usually due attention in the literature is not given.

However, the establishment of accessory drugs precedes the criminal legal evaluation of actions of the owner, associated with its use and disposal. The correct definition of the subject, which has a real opportunity to determine the fate of drugs, similar to the powers of the owner, it is important not only for differentiation of the objective side of acquisition, storage, marketing and other activities, but also for differentiating between types of partners, and in some cases forms of complicity.

At the theoretical level, the resolution of the issues of identity of drugs and legal assessment of persons involved in their trafficking is carried out by applying to the relations arising between subjects of the illegal market of drugs, analogues civil constructions proprietary and contractual relations, which are based on the idea of the owner of the drug as the owner possessing a thing from itself and for itself, in contrast to its passive holder with no right of ownership and acting in the interests of the beneficiary. Illegal relations, the subject of which is the drug transferred well-known civil law model of legal relations, the main participants of which is the owner of a thing, while other persons are carriers derived from the owner of the rights.

The author provides a critical analysis of the current doctrine of criminal law position on the possibility of applying to illegal drug deals in civil constructions proprietary and contractual relations. Substantiates the inconsistency of approaches to the separation of marketing from other activities associated with the transfer of narcotic drugs, on the basis of civil-law categories. In order to solve the qualification tasks proposed to proceed from the actual content of illicit trafficking in narcotic drugs, expressed in their assignment and alienation.

Karakterisasi yang dilakukan adalah uji ketebalan, uji kuat tarik, uji FT-IR, uji WVP, dan uji UV-Vis Spectrophotometer. Hasil dari penelitian menunjukkan bahwa penambahan nanoselulosa berpengaruh terhadap karakteristik film PVA. The Effects of Adding Nanocellulose From Oil Palm Empty Fruit Bunch (Elaeis guinensis Jacq) For Characterization of Polyvinil Alcohol (PVA) Abstract: Oil palm empty fruit bunches (OPEFB) are the largest solid waste produced by oil palm plantations. The main content of oil palm empty fruit bunches is cellulose. High cellulose content in oil palm empty fruit bunches can be used for making nanocellulose. Nanocellulose is cellulose that produced in nanoscale and it has better characteristic properties compared to cellulose. In this study, cellulose from oil palm empty fruit bunches was isolated to produce nanocellulose that can be used as filler for characterization of polyvinil alcohol (PVA). The purpose of this study is to examined the isolation of cellulose into nanocellulose from oil palm empty fruit bunches and to investiage the characteristics of PVA with the addition of nanocellulose. This study was conducted using a descriptive research design consisting of 2 (two) factors. The first factor was the total addition of nanocellulose (N) and the second factor was the amount of polyvinyl alcohol (P). The characterization that carried out were a thickness test, tensile strength, Fourier Transform Infra-Red (FT-IR), Water Vapor Permeability (WVP), and UV-Vis Spectrophotometer. The results of the study showed that the addition of nanocellulose can effect the characteristics of PVA films.

Abstrak. Indonesia negara yang mayoritas penduduknya mengkonsumsi beras sebagai makanan pokok. Usaha untuk memenuhi kebutuhan beras di masadepan akan terus dihadapkan oleh berbagai kendala seperti berkurangnya luasan pertanian, keterbatasan lahan pertanian produktif dan adanya perubahan iklim (kekeringan) serta kendala-kendala lainnya. Namun memanfaatkan lahan suboptimal Ultisol, pemberian pupuk dan melakukan perakitan varietas unggul baru diharapkan dapat mendukung usaha tersebut. Ada sebanyak 84 pot percobaan diberikan perlakuan stress air selama 21 hari. Parameter percobaan terdiri dari pertumbuhan tanaman, hasil tanaman dan kekeringan. Hasil pengujian diperoleh bahwa galur Sanbei M8-1 memiliki tingkat toleransi kekeringan yang lebih baik dibandingkan dengan galur Sanbei lainnya dan varietas Inpari 42. Jenis pupuk berpengaruh terhadap tinggi tanaman, galur/varietas dan jenis pupuk berpengaruh terhadap panjang akar saat panen. Pada percobaan ini tidak terdapat interaksi yang nyata antara perlakuan galur/varietas dan jenis pupuk terhadap pertumbuhan, hasil tanaman padi dan kekeringan. Performance of Local Rice Mutants M8 and Fertilization of Water stress in Suboptimal LandsAbstract. Indonesia is a country where the majority of the population consume rice as the staple food. In the future, the efforts to fill the need of rice will be facing by various obstacles, such as the lack of agriculture area, the limitedness in agriculture productive land, climate change (drought), other obstacle. However, the efforts will be supported by utilizing the Ultisol suboptimal land, spreading the fertilizer, and assembling the new superior variety. There are 84 pots of subject test have  treated for 21 days with water stress. The parameters consist of plant growth, productivity and water stress. The results found that galur Sanbei M8-1 has a better drought tolerance than other galur and Inpari 42 variety. Moreover, the fertilizers types not only affect the plant and galur/variety height but also affect the roots lenght. In the experiment, there is not interaction between galur/variety treatment and the fertilizer type toward the growth, productivity of paddy and water stress.
