The repeated presentation of the same information in text, illustrations or tables is to be avoided. The text must be ready for press, so that corrections will be limited to errors in typesetting. Only those contributions will be considered for publication which have been prepared under careful observation of these instructions. The papers accepted for printing will, as far as technically possible, be published according to the sequence of their arrival at the editors. Authors who have written their manuscript using a PC word processor are asked to provide the file on diskette in addition to the printout after the manuscript has been accepted for publication.
Subtitles have to be numbered according to the decimal classification.
Each paper must be accompanied by an abstract in English and German not more than 70 words in length and by a German respectively English version of the title. Equations are usually printed in italics. The symbols in the text and in the figures have to coincide. Please do not use colours for mark-up. Letters which require an underline when typeset should be highlighted and denoted in the margin by u.l.
