Coronal microleakage of restorations with or without cervical barrier in root-filled teeth Microinfiltração coronária de restaurações com ou sem barreira cervical em dentes endodonticamente tratados

Methods: Root-canal treatment was completed on 50-extracted human mandibular unirradicular. The teeth were divided into six groups: G1, positive control; G2, negative control; G3, glass ionomer (Vidrion R); G4, Coltosol + Vidrion R; G5, composite resin; and, G6, Coltosol + composite resin. For G1 and G2 five teeth each were used and for the other groups, ten teeth each. The teeth were thermocyc...

Patterns of seizure control in patients with mesial temporal lobe epilepsy with and without hippocampus sclerosis Padrões de controle de crises em pacientes com epilepsia de lobo temporal com ou sem esclerose hipocampal

Objective: Patients with mesial temporal lobe epilepsy (MTLE) may present unstable pattern of seizures. We aimed to evaluate the occurrence of relapse-remitting seizures in MTLE with (MTLE-HS) and without (MTLE-NL) hippocampal sclerosis. Method: We evaluated 172 patients with MTLE-HS (122) or MTLE-NL (50). Relapse-remitting pattern was defined as periods longer than two years of seizure-freedom...

Discipline ou spécialité: Microélectronique

Full integration of energy conversion devices for compact power supply circuits is still encountering strong technological locks, especially to integrate passive inductive and capacitive components. The increasing working frequency of those devices, which already reaches 1 Megahertz, would enable the size reduction of passive components and then their integration. Nevertheless, losses, which hi...
