On November 15th 2007, in a ceremony that it took place at the Bolivian Academy of Sciences (ANCB), Dr. Alvaro Garitano (in Biology) and myself (in Physics) have received the Prize granted by the Third World Academy of Sciences (TWAS) and the ANCB to young scientists. This iniciative is very important in countries like Bolivia in order to encourage young scientists to doing research in their own countries despite of the technical problems that they should face. I am very grateful to both Academies and I will continue my researches hoping that they could attain an appropriate scientific level.
