Article structure

Divide your article into clearly defined sections. Any subsection may be given a brief heading. Each heading should appear on its own separate line.

IntroductionState the objectives of the work and provide an adequate background, avoiding a detailed literature survey 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. Statistical methods should be included in the Material and Methods section.

Results: Results should be clear and concise.

Discussion: This should explore the significance of the results of the work, not repeat them. Avoid extensive citations and discussion of published literature.

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


Title page information

Title: Concise and informative. Titles are often used in information-retrieval systems. 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 the e-mail address of each author.

Corresponding author: Clearly indicate who will handle correspondence at all stages of refereeing and publication. Ensure that phone numbers (with country and area code) are provided in addition to the e-mail address and the complete postal address. Contact details must be kept up to date by the corresponding author.

Abstract: A concise and factual abstract is required. An abstract is often presented separately from the article, so it must be able to stand alone. For this reason, references should be avoided. Also, non-standard or uncommon abbreviations should be avoided, but if essential they must be defined at their first mention in the abstract itself. Abstracts should be structured to include items of Introduction, Material and Methods, Results and Conclusions.

Keywords: Immediately after the abstract, provide a maximum of 6 keywords, using American spelling and avoiding general and plural terms and multiple concepts (avoid, for example, 'and', 'of'). Be spa-ring with abbreviations: only abbreviations firmly established in the field may be eligible. These keywords will be used for indexing purposes.



In the main text, abbreviation should be detailed at their first mention. Ensure consistency of abbreviations throughout the article.



Collate acknowledgements in a separate section at the end of the article before the references. List here those individuals who provided assistance during the research.


Math formulae

Present simple formulae in the line of normal text where possible and use the solidus (/) instead of a horizontal line for small fractional terms, e.g., X/Y. In principle, variables are to be presented in italics. Number consecutively any equations that have to be displayed separately from the text (if referred to explicitly in the text).



Footnotes should be used sparingly. Number them consecutively throughout the article, using superscript Arabic numbers. Many word processors 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.

Table footnotes indicate each footnote in a table with a superscript lowercase letter.


Image manipulation

Whilst it is accepted that authors sometimes need to manipulate images for clarity, manipulation for purposes of deception or fraud will be seen as scientific ethical abuse and will be dealt with accordingly. For graphical images, this journal is applying the following policy: no specific feature within an image may be enhanced, obscured, moved, removed, or introduced. Adjustments of brightness, contrast, or color balance are acceptable if and as long as they do not obscure or eliminate any information present in the original.


Electronic artwork

General points

Make sure you use uniform lettering and sizing of your original artwork.

Embed the used fonts if the application provides that option.

Aim to use the following fonts in your illustrations: Times New Roman, 12.

Number the illustrations according to their sequence in the text.

Use a logical naming convention for your artwork files.

Provide captions to illustrations separately. Size the illustrations close to the desired dimensions of the printed version.

Submit each illustration as a separate file.



If your electronic artwork is created in a Microsoft Office application (Word, PowerPoint, Excel) then please supply 'as is' in the native document format.

Regardless of the application used other than Microsoft Office, when your electronic artwork is finalized, please 'Save as' or convert the images to one of the following formats (note the resolution requirements for line drawings, halftones, and line/halftone combinations given below): PDF or JPEG. Keep to a minimum of 300 dpi Vector drawings, embed all used fonts.


Please do not:

Supply files that are optimized for screen use (e.g., GIF, BMP, PICT, WPG); these typically have a low number of pixels and limited set of colors;

Supply files that are too low in resolution;

Submit graphics that are disproportionately large for the content.


Figure legends

Ensure that each illustration has a legend. Supply legends separately, not attached to the figure. A legend should comprise a brief title (not on the figure itself) and a description of the illustration. Keep text in the illustrations themselves to a minimum but explain all symbols and abbreviations used. Legends should be sent separately.



Number tables consecutively in accordance with their appearance in the text. Avoid vertical rules. Be sparing in the use of tables and ensure that the data presented in tables do not duplicate results described elsewhere in the article.



Citation in text

Please ensure that every reference cited in the text is also present in the reference list. Unpublished results and personal communications are not recommended in the reference list, but may be mentioned in the text. If these references are included in the reference list they should follow the standard reference style of the journal and should include a substitution of the publication date with either 'Unpublished results' or 'Personal communication'. Citation of a reference as 'in press' implies that the item has been accepted for publication


Web references

As a minimum, the full URL should be given and the date when the reference was last accessed. Any further information, if known (DOI, author names, dates, reference to a source publication, etc.), should also be given. Web references will be included in the reference list.


Reference style

Text: Indicate references by number(s) in square brackets in line with the text. For up to six authors, all should be listed; for more than six authors, only the first three should be listed followed by "et al".

List: Number the references in the list in the order in which they appear in the text. Note shortened form for last page number, e.g., 151-9.
