Dates and venue

The MaThCryst Satellite Conference of the 23rd European Crystallographic Meeting ECM-23 took place from Friday 4 August to Sunday 6 August 2006, at the Katholieke Universiteit Leuven, the oldest Catholic university in the world still in existence and founded in 1425.
The meeting site in and around the Falcon college is situated in the middle of the historical city center of Leuven and at walking distance of most accomodation.

The Conference was held in the René Magritte room, at the ground floor of the Oude Valk ("Old Falcon") building, Tiensestraat 41.

Program

The satellite conference was organised as a workshop-school consisting of thematic session by invited speakers, and poster presentations by the participants, and was addressed to young scientists, as well as to all those who wish to deepen their formation in the topics treated here. Each session consisted of a 1-hour lecture and 45 minutes exercises / examples.

The collected abstracts are available for download (PDF file, 771 Kb). We are gradually uploading didactic material from the invited lectures.

The schedule of the satellite was as follows:

• 8:30 - 10:15 First morning session
• 10:30 - 10:45 Coffee break and poster session
• 10:45 - 12:30 Second morning session
• 12:30 - 14:00 Lunch time and poster session
• 14:00 - 15:45 First afternoon session
• 15:45 - 16:15 Coffee break and poster session
• 16:15 - 18:00 Second afternoon session

The last day, August 6th, the afternoon sessions ended 30 minutes earlier to allow ECM-23 participants moving to the Opening Ceremony, that started at 18:00

The Organizers of the Leuven 2006 Satellite Conference on Mathematical and Theoretical Crystallography observed the basic policy of non-discrimination and affirms the right and freedom of scientists to associate in international scientific activity without regard to such factors as citizenship, religion, creed, political stance, ethnic origin, race, colour, language, age or sex, in accordance with the Statutes of the International Council for Science. At this conference no barriers existed which would have prevented the participation of bona fide scientists.
