Congress presentation formats individuals

By providing a flexible way of submitting abstracts, we are inviting you to help compose the overall congress scientific programme. Papers may be submitted as individual presentations or as a part of a symposium:

Oral Presentations: 15-minute time slot
Papers submitted to the thematic areas will be grouped together by the thematic area chairperson into paper sessions allotted of 15 minutes including discussion.

Posters: size of the poster 200 cm (height) x 90 cm (width)
Poster sessions allow presenters and attendees to engage in extended personal discussions regarding presentations that is in paper/cloth or electronical format.

NOTE: Participants who wish to submit an individual paper may choose between an oral presentation and poster. Both oral presentations and posters submitted and accepted by the Scientific Committee will be handled within the grouped by thematic sessions category topics and the best effort will be exercised to create groups of presentations related by their themes in order to promote networking among the presenters and their audience and in order to facilitate meaningful discussion. As the distinction between oral presentations and posters is only a matter of the presentation mode, submissions in both categories will be assessed by the same scientific criteria. The Scientific Committee will determine the final mode of presentation, also taking into account the quality of the proposals, their relationships, temporal and technical possibilities.
