R., Costa; P., Ferreira; M., Ferreira; R,, Castro; F., AraújoA prática da pleurodese com substâncias biológicas de características adesivas, tem sido utilizada correntemente em adultos com Fistula Broncopleural (FBP), no entanto, as referências relativas ao seu uso na idade pediátrica são muito escassas.Os autores apresentam um caso de encerramento, com sucesso, de FBP mediante pleurodese com cola de fibrina num recémnascido internado por pneumonia e pneumotórax, submeti...
Luiz Bandeira bridge : assessment of a historical rc bridge
Sena-Cruz, José; Ferreira, Rui Miguel; Ramos, Luís F.; Fernandes, Francisco; Miranda, F.; Castro, F.The Luiz Bandeira Bridge is located along the Portuguese national road EN333-3, breaching the valley of the Vouga River, just northeast of the small village Sejães, in the district of Oliveira de Frades. It is considered to be the oldest concrete bridge in use in Portugal, and one of the oldest in Europe. Since this bridge is at risk of disappearing due to a construction of a dam, the Department of Civil Engine...
Recuperação de compostos clorados e energia a partir de resíduos contendo PVC
Castro, Alexandra; Vilarinho, Cândida; Soares, Delfim; Castro, F.Os resíduos são considerados uma fonte atrativa para a produção de energia, principalmente os de base polimérica. Várias são as técnicas de valorização térmica e energética, como a pirólise, que constituem alternativas com elevado potencial no que concerne à produção de combustíveis alternativos e energia. Estas técnicas, quando aplicadas a resíduos, favorecem a formação de produtos com valor acrescentado. A ut...

Assessment of the bôco historical RC bridge
Sena-Cruz, José; Araújo, José Carlos; Castro, F.; Jorge, MarcoThe Bôco Bridge is located along the portuguese road EM595-1, breaching the valley of the Cávado river and dividing the regions of Amares and Vieira do Minho, in the district of Braga. This bridge was designed by the architect Sebastião Lopes and built in between the years of 1909 and 1910 by the company Moreira de Sá & Malevez, dealers of the patented Hennebique system in Portugal. It is considered the fourth ...
Development of a process for waste eggshell valorisation
Ribeiro, André; Graça, Jessica; Castro, F.; Vilarinho, Cândida; Carvalho, JoanaIn this work it was evaluated the adsorption efficiency of calcined eggshell from the egg-breaking operations in the treatment of wastewaters from different industrial units. It was evaluated the removal of organic material, expressed as chemically oxygen demand (COD), in leachate wastewaters from sanitary landfill (LLWW) and the municipal residual wastewaters (NWW). It was also assessed the efficiency of alkal...
Recovery of copper and nickel hydroxide from galvanic sludge : pilot scale expe...
Vilarinho, Cândida; Ribeiro, André; Carneiro, Carlos; Castro, F.The present work has been developed under the scope of the project VALMETAIS and proposes a hydrometallurgical process for copper and nickel hydroxide recovery from galvanic sludges produced by Ni/Cr plating plants. In this project. the procedure has been developed at a laboratory scale and validated at a small sized pilot plant. The developed procedure includes a first stage of a counter-current sulphuric leac...
OILCA : enhancing the competitiveness and reducing the carbon footprint of the ...
Carvalho, Joana; Ribeiro, André; Araújo, Jorge; Batista, Márcia; Castro, F.; Vilarinho, CândidaOiLCA is an international project by the INTERREG IVB SUDOE communitarian initiative. It aims to improve the competitiveness of the olive sector in the south-western Europe region, which includes Spain, Portugal and the South of France. The OiLCA methodology is based on life cycle assessment (LCA) and life cycle cost (LCC) to identify opportunities for the optimization of olive oil production. Olive oil product...
Value - exchange and technological transfer on the recovery of wastes from vege...
Carvalho, Joana; Ribeiro, André; Araújo, Jorge; Batista, Márcia; Vilarinho, Cândida; Castro, F.One of the problems associated with the vegetable processing industry on SUDOE space (South-western Europe region, which includes Spain, Portugal and the South of France), relates the management and recovery of waste and currently for many, still an unsolved problem. Among the weakness listed in the SWOT analysis of SUDOE program, the low level of waste treatment with respect to other European countries appears...
Energetic valorisation of PVC-containing waste
Castro, Alexandra; Carneiro, Carlos; Vilarinho, Cândida; Soares, Delfim; Maçães, César; Sousa, Célia; Castro, F.Wastes are increasingly regarded as important sources of energy, particularly their polymeric component. However, most of these wastes contain polyvinyl chloride (PVC) in their composition, constraining the use of a thermal valorization process in their treatment [1]. This work aims the development of a process for the material and energetic valorization of the PVC-containing wastes. A two-step process was firs...
