1. Tomographic analysis of the apical third of curved canals after endodontic treatment with different automated systems / Análise tomográfica do terço apical de canais curvos após preparo endodôntico com diferentes sistemas automatizados
This study aimed to evaluate through Beam Computed Tomography Volumetric cone (Cone-Beam), transport and the ability to centralize various automated systems. The mesiobuccal roots of maxillary first molars were divided into four groups (n=10) according to the automated systems used: GI - reciprocating with K-file Flexofile, GII - reciprocating with file NiTi

2. Estudo do desgaste e atrito de um par metálico sob deslizamento lubrificado. / Study on the wear and the friction of a metallic pair under lubricated sliding.
Este trabalho trata de um estudo experimental das respostas de desgaste e de atrito encontradas em um sistema deslizante lubrificado. Para tanto, foram realizados ensaios de deslizamento em um equipamento para ensaios de desgaste, adotando-se o dispositivo pino-contra-disco, para ensaios com movimento relativo rotativo contínuo entre as amostras, e o dispos

3. Estudo e desenvolvimento de um extrator de pratos perfurados pulsantes
Over recent years liquid-liquid extraction have become of increasing importance to chemical engineering, and the development of more efficient extractors has deserved increasing interest. Among the mechanical agitated extractors, pulsed columns have been shown to present better performance over other extractors, as the mixing occurs in the direction of de li

4. Finger tremor in Parkinson's disease.
Finger tremor was investigated in 20 patients (age range 54-88 yr) diagnosed as suffering from idiopathic Parkinson's disease and six controls of a similar age and no known neurological abnormality. In nine of the patients tremor was not clinically obvious. When the tremor of these patients was recorded immediately after voluntary movement and subjected to i
