1. Reaction Mechanisms on the 16,18O + 63,65Cu Systems / Mecanismos de Reação nos Sistemas 16,18O + 63,65Cu
The quasi-elastic excitation functions for the systems 16,18O + 63,65Cu have been measured, at the angle 161º and at energies between 30 and 48MeV, in the laboratory reference system. The quasi-elastic term refers to the sum of the elastic scattering, the inelastic scattering and the transfer reactions. Care has been taken in order to obtain high precision

2. Analysis of the nuclear fusion process based on potential barriers modified by coupling effects
Partial wave analysis and the decoupling of the wave equations based on potential barriers modifi ed by coupling effects are applied in the study of the fusion process in medium heavy nuclei. Several relevant physical quantities are calculated in order to provide evidence of underline reaction mechanisms that determine characteristics of fusion excitation fu

3. Study of the effect of the breakup on the fusion cross section of the systems 6,7Li+59Co
Fusion cross section excitation functions were measured for the 6;7Li+59Co systems (12 < Elab < 26 MeV)aiming the investigation of the effect of the breakup process on the fusion cross section. The experimental method consisted on the detection of gamma-rays from the evaporation residues. Coupled channels calculations have been performed for both systems. Th

4. Is the inhibition/enhancement of fusion due to breakup still a puzzle?
The effect of breakup in the fusion cross section in terms of suppression versus enhancement, discussed in a conflicting way in the literature, is addressed. Data and theoretical predictions available in the literature are compared. Excitation functions of the sub- and near-barrier fusion cross-sections for a wide variety of light and heavy systems are prese

5. Medidas de secções de choque de fusão dos sistemas 16o + 46,50ti / Measures sections of shock melting systems 16th ti + 46.50
Foram medidas funções de excitação para a fusão completa dos sistemas 16O+46,50Ti em energias abaixo e em torno da barreira Coulombiana. A seção de choque de fusão foi obtida utilizando-se os métodos da espectroscopia em linha e fora da linha através da soma das seções de choque dos canais de decaimento do núcleo composto formado, observados exp

6. Absence of synaptotagmin disrupts excitation-secretion coupling during synaptic transmission.
Synaptotagmin is an integral synaptic vesicle protein proposed to be involved in Ca(2+)-dependent exocytosis during synaptic transmission. Null mutations in synaptotagmin have been made in Drosophila, and the protein's in vivo function has been assayed at the neuromuscular synapse. In the absence of synaptotagmin, synaptic transmission is dramatically impair
