Oral sessions

The programme will feature two types of oral presentation sessions: one-hour (five speakers; 12 minutes per speaker including discussion) and two-hour (ten speakers; 12 minutes per speaker including discussion). These sessions are put together by the programme committee from the top rated abstracts. This is the highest category of an abstract presentation. These sessions are chaired by two experts on the topic.

Paper poster sessions

All of the accepted abstracts are scheduled for paper poster session. The paper posters are displayed in the poster area of the congress and the presentations are split in about six sessions with a poster change each day.  Each poster session will feature various topics and has a duration of one hour. The poster presenter is requested to be at her/his poster during the presentation time. Please note: strict adherence to mounting and removal times is required. Posters that are not displayed during the requested time will be marked as no shows and presenters will not receive a certificate. Also, the technical requirements for size and layout of the poster must be fulfilled.

Authors are asked to enter three keywords to better define the abstract content.
