Talks and posters: technical informations


Talks


Review talks are 40 minutes long (30'+10') and contributed talks are 25 minutes long (20'+5'). Synthesis talks are 30 minutes long (20' presentation + 10' discussion).

Remember that the deadline for abstracts is April 30.

There will be 2 computers (Mac + PC) with PowerPoint, Acrobat Reader, Open Office and Keynote installed. The speakers are requested to upload their talks on one of the conference's computer and not use their private laptop.

Poster session


Posters may be displayed for the whole duration of the symposium in the vicinity of the conference room. The posters' format is at most A0 (841 x 1189 cm), in the portrait orientation.

Remember that the deadline for abstracts is April 30. However, posters on last minute results may be considered until May 20.

We propose to print your poster locally if you wish. The deadline to receive the pdf file is June 5. The cost is CHF 17.00 per poster, to be payed at the registration desk at the beginning of the conference.
