	IUTAM SYMPOSIUM Bristol, 9-11 August 2004

Programme

There will be two lengths of talks: 45 and 30 minutes for invited and submitted presentations respectively. In both cases, speakers are encouraged to allow 5-10 minutes at the end for questions and discussion within their time slot (i.e. talks should ideally be 35-40 and 20-25 minutes respectively). There will be an overhead projector and a data projector available in the lecture room. Speakers interested in electronic presentations are kindly asked to bring their own laptops.
