A translation of the full title into English and 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. If this language is not English, an English translation of the abstract should also be submitted. Each paper should therefore be summarized in each of the two languages not used in the paper. When essential, they are numbered consecutively and typed at the foot of the appropriate page.
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. Color illustrations are reproduced at the author's expense. The list of references should include only those publications which are cited in the text. The surnames of the authors followed by initials should be given.
