To the Problem of Protection of Medium Voltage Instrument Transformers with Fuses: Analytical Research

Introduction. In the medium voltage power grid of 6–35 kV, there is a problem of protecting voltage instrument transformers. This is due to the insufficiently effective level of their protection with fuses. Recently, there have been more and more reports of accidents associated with the failure of voltage instrument transformers not only in Ukraine, but also abroad. The issue of conducting an analytical study of the problem of protection of medium voltage instrument transformers by fuses is relevant. Goal. Investigation of designs and characteristics of fuses for medium voltage instrument transformers to improve the efficiency of their protection. Results. The article shows that protection of medium voltage instrument transformers with epoxy insulation is often provided by fuses, in which the nominal current of the fuse-link is significantly higher than the maximum permissible long-term current of the primary winding of the instrument transformer. A comparative analysis of the current values of the primary winding of medium voltage instrument transformers with the values of the rated currents of the fuse-links of fuses of various manufacturers presented on the Ukrainian market is carried out. The design features and technical characteristics of fuses for medium voltage instrument transformers have been investigated in order to increase the efficiency of their protection. The advantages and disadvantages of the designs of fuses from various manufacturers have been investigated and it has been established that the design of fuses requires further improvement in order to increase the efficiency of protection of medium voltage instrument transformers. Discussion and prospects for further development. Since in Ukraine, the need for fuses to protect medium voltage instrument transformers is provided mainly by supplies abroad, a promising direction for further development in this direction is the creation of a domestic competitive design of a fuse and its introduction into production.

Building FAIR Functionality: Annotating Events in Time Series Data Using Hierarchical Event Descriptors (HED)

Human electrophysiological and related time series data are often acquired in complex, event-rich environments. However, the resulting recorded brain or other dynamics are often interpreted in relation to more sparsely recorded or subsequently-noted events. Currently a substantial gap exists between the level of event description required by current digital data archiving standards and the level of annotation required for successful analysis of event-related data across studies, environments, and laboratories. Manifold challenges must be addressed, most prominently ontological clarity, vocabulary extensibility, annotation tool availability, and overall usability, to allow and promote sharing of data with an effective level of descriptive detail for labeled events. Motivating data authors to perform the work needed to adequately annotate their data is a key challenge. This paper describes new developments in the Hierarchical Event Descriptor (HED) system for addressing these issues. We recap the evolution of HED and its acceptance by the Brain Imaging Data Structure (BIDS) movement, describe the recent release of HED-3G, a third generation HED tools and design framework, and discuss directions for future development. Given consistent, sufficiently detailed, tool-enabled, field-relevant annotation of the nature of recorded events, prospects are bright for large-scale analysis and modeling of aggregated time series data, both in behavioral and brain imaging sciences and beyond.

SOCIO-POLITICAL ACTIVISM OF OF RUSSIAN YOUTH IN THE CONDITIONS OF THE INFORMATION SOCIETY

The rapid development of digital technologies and their mass application in all areas has a significant impact on the forms of the socio-political activism of young people, as well as on the formation of young people's civic and political stances. Currently, the classical institutions of civic participation are being transformed under the influence of the digital environment, which leads to the emergence of new formations, which cover increasingly broad cohorts, have specific functioning features and tools. In the study, the author considers various approaches to work and forms of socio-political activism in the modern digital environment, identifies signs of the classification of the digital institutions of civic participation, as well as the subjects of the socio-political activism of youth in information society. The very notion of the digital institution of civic participation as a form of interaction between individuals through the digital environment is defined, which is used to implement joint goals and objectives that are relevant to all community participants. The author concludes that the interaction of traditional and digital tools, their mutual supplementation will allow to realize the socio-political needs of young people at a much more effective level, which are due to both objective age and psychophysical factors and the conditions of the external environment and current political reality.

INTERNATIONAL BUSINESS IN UKRAINE: TAX COMPONENT

In the system of regulation of international business, the tax component is of exceptional importance. The development of business is largely dependent on tax policy tools, the actual task of which is to create an optimal tax field in Ukraine, for the development of an open national economic system. The article is devoted to the study of theoretical and practical tax aspects in the international business of Ukraine. Effective level and taxation regime helps to attract foreign capital, develop international business, increase state revenues and increase gross domestic product of the country. The factors hindering the process of investing in our country are considered. The problems, as well as ways of their solution, concerning the tax component of Ukrainian business are analyzed. Detailed attention is focused on some tax aspects, which primarily include: transfer pricing rules, the rule of "thin capitalization", the rules of reporting of international groups of companies by country. Essential characteristics, features and rules of transfer pricing and "thin capitalization" are highlighted. The actions on the BEPS Action Plan are considered, which propose to eliminate the shortcomings of international tax regulation and differences in the national tax legislation of different countries, which promote "concealment" of corporate profits and its artificial transfer to low tax jurisdictions, where companies are no longer engaged in economic activity. The proposals on the improvement of bills that will recognize Ukraine as a cooperating country on taxation issues have been formed. These bills will make it possible to strengthen the economic link between Ukraine and the countries of the CIS and Eastern Europe. Recovering and strengthening these ties is the easiest to date, as each party feels that need. Right now Ukraine is taking measures for their restoration on the basis of an effective market mechanism of economic interaction.

Promising Directions in Strategic Planning of Sustainable Development of Agricultural Territories

Ensuring a stable improvement in the quality and standard of living of the rural population allows preserving the social and economic potential of rural areas. Effective management can ensure the implementation of social control and development of rural areas, the preservation of ecology, which ultimately contributes to the preservation of sustainable development of agricultural territories. The purpose of the study: To determine the directions and effective level of increasing the production of agricultural and livestock products aimed at preserving the sustainable development of agricultural territories. A correlation and regression analysis was carried out in the study to determine the promising directions of the northern districts of the Omsk region (Russia) to increase the effectiveness of strategic planning for the sustainable development of agricultural territories. Sustainable development of the regions, according to the authors, is impossible without increasing the level of well-being, therefore, the authors identified such areas for development as the cultivation of fodder crops, the cultivation of livestock and poultry (for slaughter), the cultivation of poultry for meat and the production of honey. The authors concluded that it is necessary to increase the production volumes of the selected promising areas for the development of agriculture by at least 5% to 13% per year, depending on the direction. There will be an increase in profit only at these values, which is one of the important factors contributing to the sustainable development of the areas allocated for research.

The Effectiveness of Integrated Agribusiness Cooperatives on The Income of Local Farmers

The primary problem is the limited capital owned by the farmers. This study determine agribusiness activities and analyze the effectiveness of the Integrated Agribusiness Cooperative on the income level of farmers in Subak Guama, Tabanan Regency, Bali Province. The research subject is the Subak Guama farmers who receive capital assistance, and the object is the income of farmers. This study used quantitative data with descriptive statistical analysis, namely paired sample t-test. The results showed that: (1) The Subak Guama carries out: integrated rice management activities, rice-livestock integration activities; and task to strengthen household business capital, namely independent business loans; (2) There is a difference in the level of farming income of Subak Guama farmers before and after receiving capital assistance for agribusiness cooperatives of 7.24% with an effective level of 86.69% with effective criteria.

Sincere Cooperation between EU and Member States in the Field of Readmission: The More the Merrier?

Cooperation with third countries on readmission has occupied an increasingly prominent place in the EU's migration management strategy. The EU and its Member States have progressively concluded an extensive set of bilateral and multilateral, binding and non-binding, cooperation instruments on readmission. This proliferation questions the field's coherence with the principle of sincere cooperation, governing the interplay between the Union's and Member States’ action. By taking this principle as a benchmark, the article highlights the ineffective nature of the current ‘unprincipled’ pursuit of readmission goals. It also demonstrates that sincere cooperation—if read together with subsidiarity—does not necessarily favour the Union's international action, to the detriment of the Member States’. Rather, it requires a good faith effort to identify, and stand by, the most effective level of action.

The price we pay for a specialised society: Do tax disputes require greater judicial specialisation in New Zealand?

<p>In recent years, a review of the Judicature Act and the introduction of the Judicature Modernisation Bill have enlivened the debate over the structure and character of the New Zealand court system. A key issue that the recent review and reforms have brought to the fore is whether greater judicial specialisation is advantageous at the High Court level. This paper considers whether tax cases, in particular, warrant greater judicial specialisation. The paper draws from experiences of specialised tax adjudication in foreign jurisdictions and evaluates the efficacy of existing specialisation in the New Zealand system, as well as considering whether the nature of tax law lends itself to specialisation. The conclusion is that greater judicial specialisation in respect of tax cases is undesirable. Admittedly, specialisation has been effective in many foreign jurisdictions and many characteristics of tax law favour specialisation. Yet, specialisation would come at a price in terms of the independence of tax judges and the development of idiosyncratic law. Moreover, New Zealand’s size would decimate the benefits that it could gain from further specialisation, particularly when the disputes process and the Taxation Review Authority already incorporate an effective level of specialisation to the resolution of tax disputes in New Zealand.</p>

Experience of Dexmedetomidine using for intraoperative analgosedation during ophthalmic operations

Background. The aim of the study is to evaluate the quality and safety of the sedative effect of anesthesia in ambulant ophthalmic surgery by using continuous intravenous infu­sion of Dexmedetomidine. Materials and Methods. Patients were randomized into groups by age (people from 65 to 75 years old, old age 76 years, middle age, young people, children), by gender (men, women). The physical status of patients was assessed using the ASA scale and the dynamics of vegetatic activity by the Kerdo index. Sedation was assessed using the Richmond Sedation Scale RASS.Results. It was found that the difference in the frequency of adverse effects of the appointment of Dexmedetomidine clearly confirms the need to adjust the dose of Dexmede­tomidine, depending on the state of the autonomic nervous system. The use of Dexmedetomidine according to the rec­ommendations made it possible to achieve a safe level of sedation and eliminate side effects in ambulant ophthalmic surgery.Conclusions: Parenteral continuous infusion of Dexmedetomidine pro­vides an effective level of sedation for ambulant ophthalmic surgery and maintaining patient­surgeon contact. Safety is confirmed by a low level of critical incidents, no respiratory depression at the target sedation level. The patency of the upper airways was better compared to previous experience with propofol.
