Abstract

Dear colleagues, welcome for registration (without fee payments) and abstract submission! If you cannot plan now your participations in 2020 conferences as yet, in view of the COVID19 epidemics and its consequences, please keep in mind that we intend to prolong the submission period until the time when the situation has become more predictable. Hopefully this problem will be over by the summer period and the symposium will take place within the planned time. In the worst case, if we have to shift the symposium for another period, we give you a guarantee of the full reimbursement of the registration fees if they are paid.
