It offers a comprehensive urbandisaster simulator, forums for technical discussions andcompetitive evaluation for researchers and practitioners. Thispaper explains ...
Neste momento vivemos numa era de crescimento tecnológico onde todos os dias são lançados novos produtos inovadores para o mercado que passado alguns meses podem já ser considerados ultrapassados. A acompanhar este crescimento e ao mesmo tempo sendo o seu próprio impulsionador, temos as tecnologias de comunicação sem fios a aparecer com cada vez mais largura de banda, consumos reduzidos e disseminações em massa...
O presente relatório apresenta a análise optoelectrónica de uma heteroestrutura semicondutora empilhada de fotodíodos PIN, baseada numa liga de silício amorfo hidrogenado (a-Si:H – Hyrogenated Amorphous Silicon) e siliceto de carbono amorfo hidrogenado (a-SiC:H – Hydrogenated Amorphous Silicon Carbide), cujos fotodíodos foram otimizados para deteção de sinais óticos no domínio do vis...

Understanding the environmental responses of an invasive species is critical in predicting how ecosystem composition may be transformed in the future, especially under climate change. In this study, Crassostrea gigas, a species well adapted to the highly variable intertidal environment, was exposed to the chronic environmental challenges of temperature (19 and 24°C) and pH (ambient seawater and a reduction of 0...
Tree water uptake is often estimated based in a crop coefficient kc, a ratio of the tree water uptake and a reference evapotranspiration, ET0. The concept behind estimating tree crop coefficient implies that data should be representative of the population of trees analyzed. Ideally it would require the monitoring of a large number of trees in each treatment population. This paper reports on a scaling method to ...
Thromboembolic phenomena are the most commonly reported complications during endovascular treatment of intracranial aneurysms with coils. Frequency of this complication varies in the literature, but authors reported rates ranging from 2.5 to 28%. Several mechanisms may be involved in the formation and migration of thrombus: it may be already existing inside the aneurysm and be dislocated and then migrate distal...
Endoluminal reconstruction with flow diverter devices represents an innovative technique in the treatment of intracranial aneurysms. These new stents, self-expandable and of low porosity, are released through the microcatherization of the parent artery. The main goal of these systems is thereby rebuilding the vessel wall and excluding the aneurysmal formation of the arterial circulation. We show the preliminary...
Este artigo discute o papel das artes, e do circo em particular, na construção de meios socialmente criativos que impulsionam, através da inovação social, o desenvolvimento dos lugares. Estes meios – bairros, cidades ou regiões – conjugam normalmente diversidade, tolerância, participação e memória colectiva e o circo, enquanto meio artístico, associa bem essas quatro características. Para compreender mais detal...
