Arquipélago urbano. Qualificação de áreas urbanas críticas; o caso do bairro S....

Dissertação para obtenção do grau de Mestre em Arquitetura com Especialização em Urbanismo. ; O tema incide na qualificação de áreas urbanas críticas, originadas pela inadequação da oferta habitacional às camadas desprivilegiadas da sociedade, obrigadas a ocupar zonas periféricas e isoladas da cidade, resultando na sua inevitável marginalização. Como base para a intervenção, desenvolveu-se uma pesquisa sobre o...

Oncocytic Tumors of The Adrenal Gland

The oncocytic tumors of the adrenal gland are rare. To date there’s only 147 cases published. The authors present a case of a 34 year-old man admitted to the hospital with lumbar pain and fever. At medical examination a mass was found in the left upper quadrant of the abdomen. The hormonal measurements of the adrenal gland were normal and the abdominal angio CT showed a left retroperitoneal lesion measuring 145...

Multi-scale modeling of the mechanical behavior of polymer-based materials

Polymers have become the reference material for high reliability and performance applications. In this work, a multi-scale approach is proposed to investigate the mechanical properties of polymeric based material under strain. To achieve a better understanding of phenomena occurring at the smaller scales, a coupling of a Finite Element Method (FEM) and Molecular Dynamics (MD) modeling in an iterative procedure ...

Modelling the Mechanical Behavior of Polymer-Based Nanocomposites

Molecular dynamics simulations were employed to analyze the mechanical properties of polymer-based nanocomposites with varying nanofiber network parameters. The study was focused on nanofiber aspect ratio, concentration and initial orientation. The reinforcing phase affects the behavior of the polymeric nanocomposite. Simulations have shown that the fiber concentration has a significant effect on the properties...

Knee overuse injuries in cyclists

In cyclists, overuse injuries are quite common; the knee is one of the most frequently affected anatomical sites. Knee overuse injuries can be caused by several factors and are sometimes associated with changes in mode, intensity or duration of training. Knee pain is the main clinical manifestation. In decreasing order of frequency and according to its location, knee pain can be classified as anterior, latera...
