Detailed programme

Detailed programme

The scientific program will run from 9 am to 5 pm both days. Session #1 is divided in smaller sub-sessions named in the program below. The conference will be streamed online, but there will not be an option for remote participation. All presenting authors are expected to participate in person, and non-presenting participants are of course also welcome! Please remember to register, see registration. The program is also in pdf-version and all abstracts can be found in the abstract booklet.
