Before sending a paper, authors should check the compliance of their material with all the following clauses. The materials can be returned to authors in the case the materials do not meet these requirements.

The Editorial Board accepts only original works. The standard is no less than 12 pages in length, excluding the title, keywords, the abstract, references, figures, tables, and formatting according to the requirements.

Manuscripts should be uploaded as Microsoft Word for Windows (Word document).

All margins – 2 cm, paragraph indentions – 0.5 cm. Font – Times New Roman in size – 14 with 1.5 line spacing.

When typing avoid the following:

• using macros in manuscripts files;
• text alignment using space bar (including non-breaking space);
• paragraphing using tab keys or space bar;
• inserting section breaks;
• figures appearing in tables with unmarked borders;
• using abbreviations and contractions without spelling them out at first mention.

1. The title of the scientific manuscript (The recommended length is no more than 13 words. It should reflect its content and the major problem as accurately as possible, be short but precise).
2. Copyright sign and year.
3. Information about the authors: first and last name, academic degree, academic status, occupation; affiliation with specifying the city and country; ORCID; contact (corporate) e-mail of the corresponding author.

Providing his/her e-mail in the article the author agrees to provide an open access to the article.

4. Abstract (200–250 words) should contain the brief summary of the concept of the article (read Abstract Guidelines).
5. Keywords. Minimum 5 words and/or word combinations, they should be separated by semicolon (read Keywords Guidelines).
6. Acknowledgements. Acknowledgements to individuals, granting organizations, grants numbers, etc. The granting organizations names should be written out.
7. The text of the manuscript should be structured in accordance with the rules (read Manuscript Structure).
8. REFERENCES (at least 20 sources) conformed to the formatting requirements (read References and Citations Formatting).

The abstract is one paragraph of 200–250 words. It is not permitted to divide the abstract into sections and use headings.

The abstract should be structured in the following way:

• a brief (not more than 40–60 words) justification of the relevance of the work;
• a brief (not more than 30–50 words) description of the matter the article touches upon (if it is not clear from the title);
• a brief summary of main results or conclusions. Herewith the abstract should not contain copied results or their literal repetition and conclusions, which should be given in the separate section of the article.  

When writing the abstract, the author should bear in mind that:

• The abstract is written to submit the article to abstract journals and databases;
• The abstract is read prior to the article and the conclusion about the need to address the article is made on the basis of the abstract. 

The main criterion the author should bear in mind when choosing key words is their potential value to summarize the content of the document or to help the readers to find the document. The key words may contain terms, phrases, abbreviations, numerical data, chronological data, proper names, symbols. The preferable length of the phrase is 2–3 words. Set expressions, set terms, technical terms serving as key words should not be changed as their changing leads to the loss of the term meaning. The preferable number of keywords is 5–9 words/phrases.

INTRODUCTION

The section should contain:

• Formulation of the problem to be solved by the study;
• Substantiation of the relevance of the problem under consideration;
• Research methodology (description of research stages, methods used). It is recommended to summarize it into a separate section, but it is allowed to include it in the introduction.
• Review of scientific papers on the problem under consideration;
• Goals and objectives of the study

The Introduction section should be ended with a clear statement of the purpose of the work.

Additional recommendations for writing an Introduction.

RESULTS AND DISCUSSION

This section should contain the research results and their discussion.  The results are the author’s vision of the problem under discussion, and not a description of the current situation or a listing of the opinions of other authors. Discussion of the results is a comparison of the author’s vision of solving the problem with the opinions of other authors. The text of the section should be structured in accordance with the objectives. All author’s conclusions must be based on a sufficient set of scientific arguments.

CONCLUSIONS

In this section, the main results are presented and conclusions are formulated based on the results of the study, containing scientific novelty and representing a contribution to science. The formulation of new scientific problems arising from the results obtained is encouraged.

A reference list of a scientific article is judged by the quality of the sources cited. The main requirements that are specified for sources cited in the work are their compliance with the topic under study and their trustworthiness. For scientific articles the most preferred sources are the newest articles and monographies (including the foreign ones), published over the last 3–5 years in the acknowledged journals by the authors with high scientific skills. 

References are listed in the order of citation in the article. Reference list should not include the sources not cited in the article. Each citation in the reference list should correspond with only one article. Complex citations (grouping the sources under one number) are strictly prohibited.

In the journal it is not common to cite textbooks and study guides, except the flagship in their respective field, thesis papers and synopsis of a thesis. Not less than a quarter of the sources listed in the reference list should be published in the last 3–5 years. References to print publications only are acceptable (excluding e-journals). References to internet sites are not accepted. Not more than 20 % of the sources can be references on the own author's publications.

The numbers of pages in the bibliographical entry of the source are required. If the citation refers to the independent publication (for example, a monograph), the total number of pages is given (for example, 345 p.). If the citation refers the journal article, the head and the last pages of the article are given (for example, pp. 17–19). 

If a cited source has a DOI, the DOI should be indicated at the end of bibliographic description of this source. All DOIs should be valid links.

A bibliographical entry is a set of bibliographical notes about the document cited, considered or mentioned in the text, needed and sufficient for general characteristics, identification and searching for the document. 

Bibliographical entries are used when:

• citing;
• borrowing concepts, formulas, tables, illustrations from other sources;
• paraphrasing, rewriting the text fragment in your own words;
• the reference to the other publication, where the question is discussed in a more detailed way, is needed;
• analyzing the works published.

In the text the index number of the source from the reference list is given in square brackets.
The pages number is given in square brackets only when the direct quote is used. All direct quotes should be quoted.

The simultaneous use of more than three references is not allowed. If several sources are mentioned they are separated by a semicolon (for example, [1; 2] or [3; 7; 12]) or a hyphen, if the sequence of sources is given (for example, [1–3] instead of [1; 2; 3]).

In case figures, schemas, tables in the text are taken from other publications it is necessary to refer to their sources. Herewith after mentioning the title of the figure, scheme, table “Retrieved from” is mentioned in square brackets. Then the number of the source in the reference list where the figure, scheme or table was taken from and separated by comma the number of the page, the figure, scheme or table is on in this source.
