A fixação esquelética externa, é um método de reparação de fracturas versátil, que pode conferir tanto suporte primário como auxiliar. Este sistema de fixação consiste em múltiplos pinos percutâneos transcorticais colocados proximal e distalmente à fractura, que são incorporados numa estrutura externa. É um sistema que pode ser usado após redução fechada ou aberta da fractura. Neste estudo avaliaram-se 60 anima...

With greenhouses it is possible to increase crop production and reduce significantly the water use. Additionally advancements in electronics and shortage of water have led to the development of “smart” or adaptive irrigation controllers that adjust the water application depth to plant needs, and thus increase water savings. The two most common types are soil moisture based and evapotranspiration based systems. ...
A new generation of composite pressure vessels for large scale market applications has been studied in this work. The vessels consist on a plastic liner wrapped with a filament winding glass fibre reinforced polymer matrix structure. A polyethylene (PE) was selected as liner for water at room temperatures applications and a thermosetting resin was used as matrices in the glass reinforced filament wound laminate...

While the real and historic invasions of Portugal by Napoleon were taking place, between the years 1807 and 1810, we can also note two other evasions: a real and historical one – the royal family’s escape to Brazil – and an imaginary, but equally real, one: the birth of Portuguese Pre-Romanticism, clearly dependent on an Enlightenment and revolutionary image of the Revolutionary France, which will then be lost ...
The winter of 2009/2010 was particularly severe in Northern Portugal resulting in higher river flow levels. A study was undertaken to assess the impact of this situation on several populations of freshwater bivalves (e.g., Anodonta anatina, Corbicula fluminea, Margaritifera margaritifera, Potomida littoralis and Unio delphinus) in the catchments of the Rivers Minho, Douro, Taˆ mega, Tua and Sabor. Massive die-o...
