Recommendations for oral presentations
Please meet your chairman in the preparation room at least 15 min prior your s
ession.
Use the preparation room to prepare your carousels of slides at least 30 min p
rior your session.
10 min are allotted for each presentation. A green and red light will be used
to advise the speaker to
end his presentation.
4 min of discussion is allotted at the end of each presentation.
Audio-video material available:
- Preparation room with two 35 mm slide projectors and carousels
- Amphitheatre with a very large screen. Slides should be of high quality.
- Double slide projection (35 mm).
- Video Barco projector which can display the following video format: VHS (Pal
or Secam)
and Umatic Pal. NTC is not available.
- VGA input for displaying a microcomputer screen.
- A microcomputer for assited presentation using Harvard Graphics windows.
- An overhead projector (Elmo visual presenter) using normal pages.
- A laser pointer.

Recommendations for poster presentations
All the posters presentations for the day should go up in the poster area befo
re the beginning of the
first session at 9.00 am. There will be sufficient poster boards for the posters
to remain up the whole
day that your poster is scheduled. We will have drawing pins to allow the poster
s to be attached to
the wooden boards (1,20 high x1,50 m wide). All the posters should be removed af
ter the end of the last session of the day.
A 3 min oral presentation and 2 min discussion of each poster in amphitheatre is
scheduled.
Use no more than 2 slides for presenting your summary. You can also use a video
film of 3 min if
you prefer (see format above). Because of the very tight scheduling, it is essen
tial that you do not try
to present all your data in the two slides. Please focus on the main results and
conclusions in order to
encourage questions and discussion.

REMINDER : Deadline for manuscript submission April 30, 1996

I look forward to seeing you in Saumur.

Yours Sincerely,

Dr E. Barrey,
Conference chairman
