RESUMO
The fusion excitation functions for radioactive (132)Sn + (58)Ni and stable (130)Te + (58,64)Ni were measured at energies near the Coulomb barrier. The coupling of transfer channels in heavy-ion fusion was examined through a comparison of Sn + Ni and Te + Ni systems, which have large variations in the number of positive Q-value nucleon transfer channels. In contrast with previous experimental comparisons, where increased sub-barrier fusion cross sections were observed in systems with positive Q-value neutron transfer channels, the reduced excitation functions were equivalent for the different Sn + Ni and Te + Ni systems. The present results suggest a dramatically different influence of positive Q-value transfer channels on the fusion process for the Sn + Ni and Te + Ni systems.

The aim of ELCANO, an EU-funded project, is to build a virtual multilingual multimedia library of unusual clinical cases related to gastroenterology. Based on a standardisation of the format to report and the representation of clinical information on WWW, the multilingual multimedia case has been developed and till now 350 cases have been included. User satisfaction and user acceptance of ELCANO are under evaluation.

The purpose of this study was to compare adolescents' response pattern on specific visual tasks during acute and recovered states of depression. Twenty-three inpatient adolescents with unipolar depression were tested before and four weeks after treatment. Twenty control subjects matched in age, sex, handedness, and intelligence were tested at similar intervals. Measures included four visual spatial tasks: the Gestalt Street Completion Test, the Judgment of Line Orientation, the Hooper Visual Organization Test and the Rey-Osterrieth Complex Figure. Overall, the results indicated that depressed adolescents performed significantly more poorly than controls in all four measures during both pre-and posttest conditions. They demonstrated greatest difficulty in measures of Gestalt Closure and Judgment of Line Orientation. However, the Gestalt Closure task was the only one to be correlated to severity of depression. These findings are discussed in the light of previous research suggesting a right hemisphere dysfunction and the existence of a cognitive marker in affective disorders.
