1. Volumes e Curvaturas Médias na Geometria de Finsler: Superfícies Mínimas / Volumes and Means Curvatures in Finsler Geometry: Minimal Surfaces
In Finsler geometry, we have several volume forms, hence various of mean curvature forms. The two best known volumes forms are the Busemann-Hausdorff and Holmes- Thompson volume form. The minimal surface with respect to these volume forms are called BH-minimal and HT-minimal surface, respectively. Let (R3; eFb) be a Minkowski space of Randers type with eFb =

2. Determinação da falha de um sistema de fixação da roda dianteira do Celta / Failure analisis of the celta’s front wheel fixture system
Devido ao crescimento do mercado automobilístico no país, evitar retrabalhos e reduzir custos torna-se extremamente importante para uma empresa ser cada vez mais competitiva no mercado. Este trabalho trata dois destes problemas: o alto índice de rejeições durante o aperto da porca autotravante no semi-eixo e o espanamento da rosca do parafuso da junta h

3. Implant supported prosthesis : influence of abutment and porcelain firing cycles on misfit and stress around implants / Proteses fixas implanto-retidas : influencia do pilar intermediario e dos ciclos de cocção da ceramica nos desajustes e nas tensões induzidas as fixações
It is speculated that porcelain firing cycles cause an increase on marginal misfit. This effect is imagined to origin an increase on strains around implants, when screwing the metallic frameworks, and it is supposed to be decreased by the use of an abutment between the framework and the implant. Thus, the aim of this study was to evaluate the influence of th

4. Transcatheter closure of secundum atrial septal defects with the atrial septal defect occlusion system (ASDOS): initial experience in children.
OBJECTIVE--To report initial experiences with transcatheter occlusion of atrial septal defects using a new occlusion device. SUBJECTS--10 children aged 1.1 to 14.9 years. INCLUSION CRITERIA--Patients with a body weight above 10 kg, normal pulmonary resistance and an indication for surgical closure of a secundum atrial septal defect, a residual tissue rim of
