[ICTP info point]

Dr. Crispino Luis Carlos who is a Junior Associate at ictp has left his 
personal belongings , lecture notes and other items in his personal 
mailbox (MB) on Friday 22nd around 6 p.m. He found his mail box this 
morning completely empty. Has anyone taken by mistake Dr. Crispino's 
documents? They should be returned urgently as they are of interest 
only to him. Thank you.
