1. Técnicas para a detecção, classificação e localização no tempo das variações de tensão de curta e longa duração / Techniques for detection, classification and location in time of short and long-time voltage variations
Os objetivos deste trabalho vão da apresentação do andamento das pesquisas relacionadas à análise de distúrbios associados à qualidade da energia elétrica (QEE), até a proposta de um algoritmo baseado em diversas ferramentas para a detecção e localização no tempo, bem como a classificação automática destes distúrbios. Nesta pesquisa é propo

2. Spontaneous and noradrenaline-induced transient depolarizations in the smooth muscle of guinea-pig mesenteric vein.
1. Recordings of membrane current were made in the smooth muscle of short segments of mesenteric vein before or during stimulation with noradrenaline (NA). 2. Small veins (diameter less than 150 microns) when cut into short segments (of length less than 250 microns) had the passive electrical characteristics of short cables both before and during activation

3. Post-repolarization block of cardiac sodium channels by saxitoxin.
Phasic block of rat cardiac Na+ current by saxitoxin was assessed using pulse trains and two-pulse voltage clamp protocols, and the results were fit to several kinetic models. For brief depolarizations (5 to 50 ms) the depolarization duration did not affect the rate of development or the amplitude of phasic block for pulse trains. The pulse train data were w
