Author Guidelines

• Paper is evaluated on such items as relevant, originality, practical value and technical correctness.
• Reviewers examine abstracts clarity and readability, and keyword matching to comment.
• Reviewers also check out the paper relevancy to Journal topics and predecessors works quoting.
• The important question is the scientific material organization and clarity of presentation.
• A typical length of submitted papers should be at least 6 - 8 pages. Authors with substantial work to publish can do so without a page limit.

Authors are encouraged to upload high quality, original work in English only that has not appeared in, nor is under consideration by, other journals. Extended versions of papers that have previously published in conference proceedings may also be considered (this must be indicated at the time of submission). Authors must submit their two copies of manuscript: in MS Word file (as a .doc, .docx, .rtf) and Adobe Acrobat file (as .pdf).

Please upload .pdf file as supplementary file. It is highly appreciated instead of the hard copy.

Article Formatting

• Title.
Paper title has to be informative within a reasonable number of words, but it may not include more than 90 characters. Please avoid abbreviations and formulae where possible.

• Author names and affiliations.
Where the family name may be ambiguous (e.g., a double name), please indicate this clearly. Present the authors' affiliation addresses (where the actual work was done) below the names. Indicate all affiliations with a lower-case superscript letter immediately after the author's name and in front of the appropriate address. Provide the full postal address of each affiliation, including the country name and, if available, the e-mail address of each author. Please mark an corresponding author.

• Abstract
A concise and factual abstract is required. The abstract should state briefly the purpose of the research, the principal results and major conclusions. An abstract is often presented separately from the article, so it must be able to stand alone. For this reason, References should be avoided, but if essential, then cite the author(s) and year(s). Also, non-standard or uncommon abbreviations should be avoided, but if essential they must be defined at their first mention in the abstract itself. The abstract must summarize the paper content and should have a reasonable number of words – 150-175 is an optimum number.

• Keywords
Immediately after the abstract, provide a maximum of 10 keywords, using American spelling and avoiding general and plural terms and multiple concepts (avoid, for example, 'and', 'of'). Be sparing with abbreviations: only abbreviations firmly established in the field may be eligible. These keywords will be used for indexing purposes.

• Introduction
There needs to be an adequate summary of references to describe the current state-of-the-art or a summary of the results.

• Material and methods
Provide sufficient detail to allow the work to be reproduced. Methods already published should be indicated by a reference: only relevant modifications should be described.

• Results
Results should be clear and concise.

• Conclusions
The main conclusions of the study may be presented in a short Conclusions section, which may stand alone or form a subsection of a Discussion or Results and Discussion section.

• Acknowledgements
Collate acknowledgements in a separate section at the end of the article before the references and do not, therefore, include them on the title page, as a footnote to the title or otherwise. List here those individuals who provided help during the research (e.g., providing language help, writing assistance or proof reading the article, etc.).

• Subdivision
Divide your paper into clearly defined and numbered sections. Subsections should be numbered 1.1, 1.2, etc. (the abstract is not included in section numbering). Use this numbering also for internal cross-referencing: do not just refer to 'the text'. Any subsection may be given a brief heading. Each heading should appear on its own separate line.

• Formulae
Mathematical expressions and Greek or other symbols must be written clearly with ample spacing.

• Units
Follow internationally accepted rules and conventions: use the international system of units (SI). If other units are mentioned, please give their equivalent in SI.

• Footnotes
Footnotes should be used sparingly. Number them consecutively throughout the article, using superscript Arabic numbers. Many wordprocessors build footnotes into the text, and this feature may be used. Should this not be the case, indicate the position of footnotes in the text and present the footnotes themselves separately at the end of the article. Do not include footnotes in the Reference list.

• References

At least 25 quality references should be cited.

References must appear as a separate bibliography at the end of the paper, numbered by numerals in square brackets.
References to papers published in languages other than English must be translated into English indicating the original language given in brackets in the end of the reference e.g. (in German).
References in the text are indicated in square brackets. Journal titles must not be abbreviated. Please give journal volumes, issues (numbers) and page numbers.

• Figures
Electronic version in EPS (Encapsulated Postscript) is preferred. The illustrations must be sharp, noise free and of good contrast.

Please do not:
- Supply files that are optimised for screen use (e.g., GIF, BMP, PICT, WPG); the resolution is too low;
- Supply files that are too low in resolution;
- Submit graphics that are disproportionately large for the content.
