The abstract can be inserted only within the registration. After selecting the option of an active oral presentation or a poster the part of the registration form where an abstract can be inserted will appear. It could be uploaded as a text or as a file directly from the computer. The abstract is sent along with the registration data and cannot be uploaded later. In this case of an active participation when an abstract is nod uploaded during the registration, the registration cannot be completed. For further information you can contact the conference organisers.
