I wish to thank my collaborators and usual “problem solvers” for their professionalism, friendship and patience:

M. Àngels Lladó, Oriol Rigat, Sandra Salvador, Aurelio Sánchez, Laura Cantarella, Isabel Hortal, Mercè Amat, Reinhard Steger, Joan Fusté, Clara Gràcia, Ynès Montràs, Estela Robles, Dolors Soriano, Maite Ilundain, Brigitte Hübner and David Lorente.

Thanks to Ramon Prat and the "ACTAR family" for many years of work, trips, experience and friendship.

Thanks to everybody who has entrusted me with their projects, to my “die-hard fans” for making me believe I am somebody special and to my friends and family for putting up with my “ups and downs”, times of doubt and freak-outs.

Thanks to everybody,
