A displacement formulation for cylindrical shells subjected to radial loads is presented. Static loads are applied to straight thin pipes using a variational method and results are compared both to finite element analysis and a shell element from Ansys program. The formulation includes a combination of trigonometric functions in two variables, longitudinal and circumferential direction. Then a system of differe...
O estudo foi realizado no período de fevereiro de 2007 a maio de 2008, em vinte e uma comunidades rurais do município de Oeiras (07º00'54''S e 42º08'06''W), localizadas em área de transição vegetacional Caatinga/Cerrado, onde predomina a Caatinga. Objetivou-se conhecer as plantas tradicionalmente utilizadas pela população com fins terapêuticos. As coletas botânicas seguiram metodologia usual e os exemplares ide...
Schist constructions represent an important cultural, architectural and historical legacy in Europe, and particularly in Portugal, that urges to preserve. Included among the traditional Portuguese architectural heritage, there are many traditional buildings in schist masonry, distributed from North to South, varying the types of buildings, the constructive methodologies and even the material schist, which may v...
The present work describes part of the R&D on using a semi-active structural control technique in a civil engineering experimental model frame equipped with a MR damper, developed within COVICOCEPAD project approved in the framework of Eurocores program S3T. Some results are provided associated with the calibration of a MR damper at FEUP as well as on the experimental modal identification of the dynamic propert...
O presente trabalho pretende apresentar parte da investigação desenvolvida no âmbito do projeto COVICOCEPAD relativa ao controlo semi-activo de estruturas de engenharia civil através da utilização de amortecedores Magneto-Reológicos (MR). Para este efeito foi construído um modelo numérico que permite a inclusão do comportamento do martecedor MR no modelo estrutural através de uma formulação em espaço de estado....

The purpose of this study was to characterize the clinical and serological features of a large cohort of patients with antinuclear antibody (ANA) positive undifferentiated connective tissue disease (UCTD). Consecutive patients with UCTD, followed up at the Rheumatology Clinic of the participating centers, were included. Data from these patients were obtained by clinical evaluation and chart review. All patients...
As construções em xisto representam um legado cultural, arquitectónico e histórico muito importante em Portugal e na Europa, que urge preservar. Em Portugal, as construções tradicionais em xisto encontram-se dispersas por diversas regiões, de Norte a Sul, variando as tipologias das construções, as metodologias construtivas e até o próprio xisto. Os danos mais comuns neste tipo de construções são devidos ao defi...
Resumo indisponível.
The Podestà Palace, a historical masonry construction, is dated from the XII century and is situated in Foligno, central Italy. This building has a high heritage and artistic value associated to it, mainly due to existing paintings in both the internal and external parts of the façade. Its current deteriorated state, coupled with the high seismic hazard of the region, stresses the pronounced seismic risk associ...
