The in vitro mechanical properties of small diameter Poly(vinyl) alcohol hydrog...
Alexandre, Nuno; Nunes, Natacha; Rodrigues, Miguel; Maurício, Ana Colette; Luís, Ana Lúcia; Lopes, Ascensão; Santos, José DomingosIntroduction The production of artificial vascular grafts of small diameter is a fluorescing line of investigation. PVA is a biomaterial that has been used for several biomedical applications and nowadays as a vascular graft. However the mechanical properties were never characterized in vitro. It was our objective to produce small diameter PVA grafts and characterize their physical and mechanical properties for...

Avaliação da heterogeneidade das propriedades mecânicas de um BACRFA em element...
Barros, Joaquim A. O.; Lourenço, Lúcio; Gonçalves, Delfina; Durães, Bárbara; Alves, Nuno; Nunes, ÂngelaO presente trabalho refere-se à avaliação da heterogeneidade das propriedades mecânicas de um Betão Auto-Compactável Reforçado com Fibras de Aço (BACRFA) ao longo de elementos estruturais. O programa experimental foi composto por séries de elementos com diferentes alturas e distintos comprimentos de modo a avaliar a influência da direcção preferencial de fluxo do BACRFA nas propriedades deste. O estudo acerca d...
ESTG Cargo 2 Team - 2009 AirCargo Challenge Report
Rodrigues, Nuno; Nunes, Tiago; Santos, Marco; Pires, António; Abreu, Dinarte; Farinha, Eduardo; Marques, Luís; Gomes, Nuno; Mouta, RodolfoThis document describes the main aspects of the design process, including some of the approaches that were chosen by the team to achieve the objectives of the ACC, namely to create a radio controlled (RC) aircraft that will lift the most weight, while meeting a set of specifications. Detailed drawings of the ESTG-IPL Cargo plane will be presented, together with the technical and experimental considerations that...
