Articles may be submitted online to this journal. Editable files (e.g., Word, LaTeX) are required to typeset your article for final publication. All correspondence, including notification of the Editor's decision and requests for revision, is sent by e-mail. Contributions to this journal may be submitted either online or outside the system.

Text should be typed double-spaced, in a double  column using 12-point type



Use of word processing software

It is important that the file be saved in the native format of the word processor used. The text should be in double-column format. Keep the layout of the text as simple as possible. Most formatting codes will be removed and replaced on processing the article. In particular, do not use the word processor's options to justify text or to hyphenate words. However, do use bold face, italics, subscripts, superscripts etc. When preparing tables, if you are using a table grid, use only one grid for each individual table and not a grid for each row. If no grid is used, use tabs, not spaces, to align columns. The electronic text should be prepared in a way very similar to that of conventional manuscripts


Article structure


If there is more than one appendix, they should be identified as A, B, etc. Formulae and equations in appendices should be given separate numbering: Eq. (A.1), Eq. (A.2), etc.; in a subsequent appendix, Eq. (B.1) and so on. Similarly, for tables and figures: Table A.1; Fig. A.1, etc.


     Essential 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. Please clearly indicate the given name(s) and family name(s) of each author and check that all names are accurately spelled. You can add your name between parentheses in your own script behind the English transliteration. Present the authors' affiliation addresses (where the actual work was done) below the names. Indicate all affiliations with a lower­case 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.

Corresponding author. Clearly indicate who will handle correspondence at all stages of refereeing and publication, also post-publication. This responsibility includes answering any future queries about Methodology and Materials. Ensure that the e-mail address is given and that contact details are kept up to date by the corresponding author.

affiliation address. Superscript Arabic numerals are used for such footnotes.


Abstract (250 words maximum) should be a summary of the paper and not an introduction. Because the abstract may be used in abstracting journals, it should be self-contained (i.e., no numerical references) and substantive in nature, presenting concisely the objectives, methodology used, results obtained, and their significance.


Subject terms or keywords are required, maximum of eight. Key words referring to the special contents of the publication, and not to its methods. The editor retains the right to change the Key words.


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.).


Math formulae

Please submit math equations as editable text and not as images.


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: Arial, Courier, Times New Roman, Symbol, or use fonts that look similar.
  • 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 published version.
  • Submit each illustration as a separate file.


  • TIFF (or JPEG): Color or grayscale photographs (halftones), keep to a minimum of 300 dpi.
  • TIFF (or JPEG): Bitmapped (pure black & white pixels) line drawings, keep to a minimum of 1000 dpi. TIFF (or JPEG): Combinations bitmapped line/half-tone (color or grayscale), keep to a minimum of 500 dpi.
  • Please do not:
  • Supply files (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 captions

  • Ensure that each illustration has a caption. Supply captions separately, not attached to the figure. A caption 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.



Size your illustrations according to the journal’s specifications for column widths. Figures are generally reduced to either one-column width (8.8 cm) or smaller. Submit each illustration at the final size in which you would like it to appear in the journal. Each illustration should be prepared for 100% reproduction. •Avoid submitting illustrations containing small axes with oversized labels. •Ensure that line weights will be 0.5 points or greater in the final published size. Line weights below 0.5 points will reproduce poorly.


Tables should bear consecutive numbers. Please add headings immediately above the tables


Reference management software

 Using citation plugins from products styles, such as Mendeley or Endnote plugin.
