Manuscript Preparation:General: Editors reserve the right to adjust style to certain standards of uniformity. Original manuscripts are discarded one month after publication unless the Publisher is asked to return original material after use. Please use Word, Word Perfect or LaTeX files for the text of your manuscript. (For further information about LaTeX submission, please go to http://www.elsevier.com/locate/latex.) For initial submission please convert to a pdf.Back to contents list

Structure: Follow this order when typing manuscripts: Title, Authors, Affiliations, Abstract, Keywords, Main text, Acknowledgements, Appendix, References, Figure Captions and then Tables. Embedded images in text pdf for initial email submission. The author must supply the final accepted paper text in word, word perfect or latex, and images in original graphics files, see illustrations and winzipped, to the editor by email. Collate acknowledgements in a separate section at the end of the article and do not include them on the title page, as a footnote to the title or otherwise.Back to the contents list

Text Layout: Use single column, double spacing and wide (3 cm) margins. (Avoid full justification, i.e., do not use a constant right-hand margin.) Ensure that each new paragraph is clearly indicated. Add line numbers in the margin alongside each line of the document. (This can be automated using the page layout/line numbering facility in WORD.) Present tables and figure legends on separate pages at the end of the manuscript. If possible, consult a recent issue of the journal to become familiar with layout and conventions. Number all pages consecutively, use 12 pt font size and standard fonts.Back to the contents list

Corresponding author: Clearly indicate who is responsible for correspondence at all stages of refereeing and publication, including post-publication. Ensure that telephone and fax numbers (with country and area code) are provided in addition to the e-mail address and the complete postal address. Full postal addresses must be given for all co-authors. Please consult a recent journal paper for style if possible. Back to the contents list

Abstract: A self-contained abstract outlining in a single paragraph the aims, scope and conclusions of the paper must be supplied. Back to the contents list

Keywords: Immediately after the abstract, provide a maximum of six keywords (avoid, for example, 'and', 'of'). Be sparing with abbreviations: only abbreviations firmly established in the field may be eligible. Back to the contents list

Units: Follow internationally accepted rules and conventions: use the international system of units (SI). If other quantities are mentioned, give their equivalent in SI in parentheses. Temperatures should be given in degrees Celsius. The unit 'billion' is ambiguous and should not be used.Back to the contents list
