Guide for Authors

Formatting Requirements

  • Articles with text uniqueness of at least 70% are accepted for publication (anti-plagiarism)
  • The size of the article is at least 4 pages (but not more than 20 pages), including figures and tables placed in the text by reference (the ratio of figures and tables to text is 30 to 50%).
  • Do not include a title page or abstract. (Begin the document with the introduction; a title page, including the abstract, will be added to your paper by the editors.)
  • Do not include page numbers, headers, or footers. These will be added by the editors.
  • Write your article in English (unless the journal expressly permits non-English submissions).
  • Submit your manuscript, including tables, figures, appendices, etc., as a single file (Word, RTF, or PDF files are accepted).
  • All margins (left, right, top and bottom) should be 2.5 cm, including your tables and figures.
  • Font:
    1. Main Body—12 pt. Times New Roman
    2. Footnotes—10 pt. Times New Roman
  • The abbreviation used in the text is deciphered at the first use.

The article must contain:

  • UDC (placement in the left corner of the document);
  • Title of the article (in capital letters) in English language; bold font, size 12, placement in the center of the document;
  • Information about the authors in English language (see an example of article design):
  • Full name of the authors;
  • Academic degree, position;
  • Place of work and unit (institute, department, etc.)
  • Postal address of the place of work;
  • Authors email.
  • An annotation (English language) of at least 100 words, which should reflect the relevance and purpose of the study, methods, results, conclusions;
  • Keywords (at least 7 words or phrases in English language).

The design of figures, tables and formulas in the text of the article:

  • Image files (preferably color) in jpg, tif, cdr, vsd or other formats of vector editors Corel Draw, Microsoft Visio, etc., as well as special graphic editors, such as Adobe Photoshop, with a resolution of at least 300 dpi are attached to the article.
  • Signature of figures and tables (English language): Fig. 1. Name; Title, Table 1. Name; Title
  • Draw fractions and intervals as 1.2 ... 1.8 mm; 5-7 pcs.
  • If the length of the formula exceeds half the width of the page, it is necessary to break the formula into fragments due to the fact that the texts of articles in the journal are arranged in two columns.
  • Only those formulas referred to in the text are numbered in italics — letters of the Latin alphabet, except for the proper names, designations of standard mathematical functions and chemical elements (Ф, µ, но Аl2О3, cosα, max, lg, «BASF»). Vectors are in bold italics.
  • The text of the article uses quotation marks of the form "...".
  • Mandatory presence of conclusions at the end of the article.
  • Bibliography:
  • Drawn up in accordance with the rules of the journal (see. example of the design of the article);
  • Formed in accordance with the mention of sources in the text of the article, for example: [1, 2] or [3–7];
  • A cited list of literature must be transliterated using the Roman alphabet (Latin; see an example of article design).

Additional Recommendations

Indenting, Line Spacing, and Justification

Indent all paragraphs except those following a section heading. An indent should be at least 2 em-spaces.

Do not insert extra space between paragraphs of text with the exception of long quotations, theorems, propositions, special remarks, etc. These should be set off from the surrounding text by additional space above and below.

Don't "widow" or "orphan" text (i.e., ending a page with the first line of a paragraph or beginning a page with the last line of a paragraph).

All text should be left-justified (i.e., flush with the left margin—except where indented). Where possible, it should also be right-justified (i.e., flush with the right margin). "Where possible" refers to the quality of the justification. For example, LaTeX and TeX do an excellent job of justifying text. Word does a reasonable job. But some word processors do a lousy job (e.g., they achieve right justification by inserting too much white space within and between words). We prefer flush right margins. However, it is better to have jagged right margins than to have flush right margins with awkward intra- and inter-word spacing. Make your decision on whichever looks best.

Language & Grammar

All submissions must be in English. Except for common foreign words and phrases, the use of foreign words and phrases should be avoided.

Authors should use proper, standard English grammar. The Elements of Style by William Strunk, Jr. and E. B. White (now in its fourth edition) is the "standard" guide, but other excellent guides (e.g., The Chicago Manual of Style, University of Chicago Press) exist as well.

Article Length

Because this journal publishes electronically, page limits are not as relevant as they are in the world of print publications. We are happy, therefore, to let authors take advantage of this greater "bandwidth" to include material that they might otherwise have to cut to get into a print journal. This said, authors should exercise some discretion with respect to length.

Colored text

Set the font color to black for the majority of the text. We encourage authors to take advantage of the ability to use color in the production of figures, maps, etc., however, you need to appreciate that this will cause some of your readers problems when they print the document on a black & white printer. For this reason, you are advised to avoid the use of colors in situations where their translation to black and white would render the material illegible or incomprehensible.

Please ensure that there are no colored mark-ups or comments in the final version, unless they are meant to be part of the final text. (You may need to "accept all changes" in track changes or set your document to "normal" in final markup.)

Emphasized text

Whenever possible use italics to indicate text you wish to emphasize rather than underlining it. The use of color to emphasize text is discouraged.

Font faces

Except, possibly, where special symbols are needed, use Times New Roman or the closest comparable font available. If you desire a second font, for instance for headings, use a sans serif font (e.g., Arial or Computer Modern Sans Serif).

Font size

The main body of text should be set in 12pt. Avoid the use of fonts smaller than 6pt.

Foreign terms

Whenever possible, foreign terms should be set in italics rather than underlined.


Headings (e.g., start of sections) should be distinguished from the main body text by their fonts or by using small caps. Use the same font face for all headings and indicate the hierarchy by reducing the font size. There should be space above and below headings.

Main text

The font for the main body of text must be black and, if at all possible, in Times New Roman or closest comparable font available.


Whenever possible, titles of books, movies, etc., should be set in italics rather than underlined.


Footnotes should appear at the bottom of the page on which they are referenced rather than at the end of the paper. Footnotes should be in 10 pt. Times New Roman or closest comparable font available, they should be single spaced, and there should be a footnote separator rule (line). Footnote numbers or symbols in the text must follow, rather than precede, punctuation. Excessively long footnotes are probably better handled in an appendix. All footnotes should be left and right-justified (i.e., flush with the right margin), unless this creates awkward spacing.

Tables and Figures

To the extent possible, tables and figures should appear in the document near where they are referenced in the text. Large tables or figures should be put on pages by themselves. Avoid the use of overly small type in tables. In no case should tables or figures be in a separate document or file. All tables and figures must fit within 1.5" margins on all sides (top, bottom, left and right) in both portrait and landscape view.


Roman letters used in mathematical expressions as variables should be italicized. Roman letters used as part of multi-letter function names should not be italicized. Whenever possible, subscripts and superscripts should be a smaller font size than the main text.

Short mathematical expressions should be typed inline. Longer expressions should appear as display math. Also expressions using many different levels (e.g., such as the fractions) should be set as display math. Important definitions or concepts can also be set off as display math.

Equations should be numbered sequentially. Whether equation numbers are on the right or left is the choice of the author(s). However, you are expected to be consistent in this.

Symbols and notation in unusual fonts should be avoided. This will not only enhance the clarity of the manuscript, but it will also help insure that it displays correctly on the reader's screen and prints correctly on her printer. When proofing your document under PDF pay particular attention to the rendering of the mathematics, especially symbols and notation drawn from other than standard fonts.


  • References should include 15 or more sources; reference to own works - no more than 20% of the total number of sources; the list of references must contain references to modern sources (not older than three years at the time of publication of the article, 20%) and foreign sources (40% of the total).
  • It is the author's obligation to provide complete references with the necessary information. After the last sentence of your submission, please insert a line break—not a page break—and begin your references on the same page, if possible. References should appear right after the end of the document, beginning on the last page if possible. References should have margins that are both left and right- justified. You may choose not to right-justify the margin of one or more references if the spacing looks too awkward. Each reference should give the last names of all the authors, their first names or first initials, and, optionally, their middle initials. The hierarchy for ordering the references is:

    1. Last name of first author
    2. First name of first author
    3. Last name of second author (if any). Co-authored work is listed after solo-authored work by the same first author (e.g., Edlin, Aaron S. would precede Edlin, Aaron S. and Stefan Reichelstein).
    4. First name of second author
    5. Publication date
    6. Order cited in text

    The information to be given with each citation in the references is as follows:

    Articles in traditional journals:

    Required: Author's (authors') name(s), title of article, name of journal, year of publication (or "n.d." if no date), volume number, page numbers.

    Optional (but desirable): issue number and month/season of publication. For forthcoming (in press) articles, put expected year of publication and substitute "forthcoming" for the volume and page numbers.

    Optional(but desirable): A hyperlink to the article.

    The editors do not accept articles for publication if an identical article has already been published in other media. Authors of the material in English accept the obligation not to transmit such materials for publication in other media. The editors reserve the right to terminate further work with authors who violate this requirement.

    The fact that the article was submitted to the editorial office for publication confirms the author’s consent to all the requirements presented.

    The high-tech text of the manuscript is submitted to the editor in two copies; both copies of the article must be signed by all authors. The article is submitted in electronic form.
