general significance and contain relevant references. All the
abstracts will be included in an Abstract volume that will be
distributed at the beginning of the workshop. Please, follow
carefully the instructions for preparation of abstracts, in order to
ensure standardized formats. The abstract must contain the full
name, full address and e-mails of author/s. In the case of joint
