Oral presentations will be made in specific sessions, some of which will be introduced by a keynote. The total time allocated to each presentation is 12 minutes, but you should allow 2-3 minutes of these for discussion. For much of the time, there will be parallel sessions located in rooms in the same conference area, but it will be very easy to move between rooms. Therefore, it is essential that speakers keep to the time schedule and do not exceed the time allocated. Chairpersons will be under strict instruction to stop any presentation that is running over time. The use of video equipment is not allowed.
