PRESENTATIONS -- Every paper printed in the Proceedings must be presented by one of the authors either in an oral session or in a poster session. Whether the paper is to be presented in an oral session or in a poster session will be decided by the International Scientific Committee in view of the author's selection at the submission of the abstract and also the topic dealt with in the paper, not necessarily considering the scientific quality of the paper. The number of papers assigned for oral presentations will be limited in order to leave enough time for discussions from the floor and to provide more time for poster sessions. The majority of contributed papers will be presented by posters.
