instructions to authors

The Proceedings of the Estonian Academy of Sciences is an open access journal that publishes internationally peer reviewed primary research and review papers in the fields of sciences represented at the Estonian Academy of Sciences (mathematics, physics, chemistry, cosmology, industrial engineering etc.). The manuscripts submitted should be written in English and meet the following requirements.

Manuscript elements should be in the following order: Title, Abstract, Key words, Introduction, Materials and methods, Results, Discussion, Conclusions, Acknowledgements, Appendixes (if any), References.

Authors of the article should name the subject by which the field of the article can be determined.

The title should be concise but informative. The arrangement and selection of words is important for indexing purposes. A short running title should be provided.

The name(s), including one forename in full, affiliation(s), and full affiliation address(es) of the author(s) should follow the title of the paper. The corresponding author should be marked by an asterisk and his/her e-mail address should be given.

The abstract (not more than 250 words) should be a self-contained summary of the paper, presenting concisely the objectives of the work reported, methodology, results and conclusions. Mathematical expressions and citations in the abstract should be avoided. The abstract should be followed by key words (max seven) with the first key word indicating the discipline of the study.

The introduction should be a review of pertinent work, cite appropriate references, as well as include a clear statement of the object of investigation.

The length of an article should be maximally 12 pages (including figures, tables and references). Each page exceeding this volume shall be liable to a fee to the amount of €62 per page.

Conclusions should give a short summary of the achieved results followed by possible further steps and extensions.

Acknowledgements of people, grants, funds, etc. should be placed in a separate section before the reference list. The names of funding organizations should be written in full. The  institution(s) or person(s) covering the publication costs must be shown in this section.

The volume of the manuscript (incl. references, summaries, illustrations, and tables) is preferably no more than 26 double-spaced pages.

It is essential that the paper be written in clear, proper English (British or American usage is accepted, but not a mixture of these). Manuscripts requiring substantial improvement of English usage may be returned to the author(s) for revision before the review process. Authors for whom English is not their mother tongue should have their manuscripts checked by a competent linguist or native English speaker before submission. The editors reserve the right to adjust style to certain standards of uniformity.


Manuscripts for the Proceedings of the Estonian Academy of Sciences should be submitted online. The submitting author, who is generally the corresponding author, is responsible for the manuscript during the submission and peer-review process.

Word versions are preferable in case the manuscript does not include complicated formulas. The authors are asked not to use specially defined macros. If it has been necessary to define the commands, they should be added to the text file.

notations and abbreviations

Notations must be clear, compact, and consistent with standard usage. All notations and abbreviations should be defined in the text. Avoid abbreviations in the title and abstract. The full term for which an abbreviation stands should precede its first use in the text unless it is a standard unit of measurement.

Equations should be numbered consecutively with equation numbers enclosed in parentheses at the right margin of the page. In the text, reference to an equation should be in the form of an equation number enclosed in parentheses.

Illustrations should be prepared in their final format (i.e. no enlarging or reducing will be necessary) and fit into the print area of the journal. All illustrations should be sharp and readable. The maximum size of an illustration is that of one journal page (166 mm × 228 mm) or of one column (80 mm × 228 mm). All illustrations must be clearly numbered. Each illustration should be indicated at the appropriate place in the text. All illustrations must have self-explanatory legends. The text, tables, and illustrations should not repeat one another.

The lettering (upper- and lowercase letters, italic, bold) should follow the usage in the text. Different parts of a figure should be marked by lowercase letters in parentheses. The size of symbols and lettering should not be smaller than 1.5 mm.

Photographs (digital or scanned) should be saved as .tif or .eps files at a resolution of at least 300 dpi.

Colour illustrations should be in RGB and CMYK mode (resolution at least 300 dpi). Authors will be asked to cover the full cost for reproduction of colour artwork at a rate of €35 for one printed page. Colour figures online will be published free of charge.

References to the literature cited should be indicated at the appropriate place in the text. Either the author–year (Harvard) or numerical (Vancouver) style of citing may be used. All references included in the list of references should also appear in the text and vice versa. Use abbreviated titles of journals in the list of references.

References to papers by the same author are sorted according to the number of authors (one, two, three or more). Those of a single author, ordered chronologically, are followed by papers with two authors arranged in alphabetical order according to the name of the second author (and chronologically, if needed). Papers with three or more authors, e.g. cited in the text as Jones et al., should be given in chronological order after those with two authors.

If the author–year style is used, references to the literature should be indicated at the appropriate place in the text by using the name(s) of the author(s) and the year of publishing. A reference list in alphabetical order should appear at the end of the article.

All articles published in the Proceedings of the Estonian Academy of Sciences are freely available to read, download, re-use and share for non-commercial purposes.

When submitting an article to the Proceedings of the Estonian Academy of Sciences, the corresponding author agrees to pay the article processing charges (APC). Article processing charges (standard article publication fee or ‘fast track‘ fee, the excess page fee and cost of colour illustrations) are payable by the author, their institution or funder of the research.

Invoice with the banking data will be sent to the corresponding author. Prompt payment is advised, as the article will not be sent to the production cycle until payment is received. Payment should be made in Euro to the bank account of the Estonian Academy Publishers.

To partly cover publication costs of papers, the Estonian Academy Publishers charges a standard article publication fee of €500 per publication of papers up to 12 printed pages. For all papers longer than 12 printed pages, an additional page charge of €62 will be requested for each extra page. Authors will be asked to cover the full cost for reproduction of colour artwork at a rate of €35 for one printed page. Colour figures online will be published free of charge.

Standard article publication fee (max. 12 printed pages)500
Excess page fee (printed page)62
Colour illustrations (one printed page)35
‘Fast track‘ publication fee *1000

* ‘Fast track‘ publication fee includes colour figures.

No handling fee is applied to the manuscripts rejected by the publisher.

The publication fee of articles up to 12 printed pages will be waived by the Estonian Academy of Sciences to the authors whose work was supported by Estonian granting agencies or other Estonian funding bodies and the authors have explicitly stated this information in the Acknowledgements section. Requests for waivers of publication and/or excess page fees should be presented in the covering letter.

The authors of review papers are free of publication fees and additional charges for extra pages. Authors will be asked to cover the full cost for reproduction of colour artwork at a rate of €35 for one printed page. Colour figures online will be published free of charge.

fast track

After the final decision about manuscript acceptance the authors have a possibility of applying for ‘fast track‘ publication. If this application is accepted, the paper will be included in the next issue. Due to the extra publication costs, the authors will be asked to pay ‘fast track‘ publication fee. ‘Fast track‘ publication fee includes colour figures.


The author (or the corresponding author) will receive a PDF file for correcting printer’s errors. No changes may be made and no new material inserted in the text at the time of proofreading.


Payable offprints of an article (minimum 10 copies) can be ordered from the Editorial office at proof stage.
