A short course (school) has been planned suitable for students, plant engineers, operators
and researchers in the field, prior to the start of the conference. The organizing committee encourages delegates to seize this opportunity.
Short Course Provisional Programme
Tuesday, 18th November 2008
Please note: The short course is prior to IFSA 2008 Conference. Please register separately.
