If an abstract or a question is not acknowledged within 2 working days, please assume that it was not received. Do not send the abstract more than once. If you e-mail it, do not send a copy in the postal mail. If you send it via postal mail, do not e-mail it. Special characters, tables, mathematical formulae and figures are allowed in the word processor file, but please try to keep to a minimum.
Mathematical formulae are to be written on a single line with sub and superscripts only.
No big fractions. Special symbols and Greek characters should be confined to the set of fonts that come with the standard distribution of Microsoft Word or WordPerfect. Add-on fonts, such as those for mathematical formulae, must be avoided as these may not be available at the abstract processing office. Send one hardcopy of the abstract with the diskette to the following address. Instructions for e-mail.
