10 pages including figures, tables and references. A short title for use as running head as well as the full address of the author to whom correspondence should be sent are also required. Please also supply phone and fax numbers, as well as your e-mail address. The abstract is of utmost importance.

Tables require a heading and figures a legend, also prepared on a separate sheet.
Due to technical reasons, figures with a screen background should not be submitted. On the back of each illustration, indicate its number, the author's name, and 'top' with a soft pencil. During the review process, the decision will be made as to which color illustrations of a manuscript can be reproduced free of charge. Authors will be informed of this at the time of acceptance of their paper. Otherwise, these illustrations will be reproduced at the author's expense.
