Arachnoid Cyst Spontaneous Rupture
Marques, Inês Brás; Serviço de Neurologia. Centro Hospitalar e Universitário de Coimbra. Coimbra. Portugal.Arachnoid cysts are benign congenital cerebrospinal fluid collections, usually asymptomatic and diagnosed incidentally in children or adolescents. They may become symptomatic after enlargement or complications, frequently presenting with symptoms of intracranial hypertension. We report an unusual case of progressive refractory headache in an adult patient due to an arachnoid cyst spontaneous rupture. Although c...
How to address sustainability at the city level
Barbosa, José Amarilio; Bragança, L.; Mateus, RicardoA brief analysis of the environmental, social and economic paradigm of nowadays cities, allows reaching a conclusion: current cities are not sustainable. Considering this, it is very important to study the causes of such unsustainability and to develop models for sustainable cities. There are a limited number of studies in this area, but the scientific community lacks even more studies related to the implementa...
Solving flexible job shop scheduling using genetic algorithm
Pereira, Ana I.; Curralo, Ana; Barbosa, José; Leitão, PauloThis work addresses a real assembly cell: the AIP-PRIMECA cell at the Université e de Valenciennes et du Hainaut-Cambrésis, in France. This system can be viewed as a Flexible Job Shop, leading to the formulation of a Flexible Job Shop Scheduling Problem (FJSSP). This FJSSP offers the possibility to create the products "AIP", "LATE" and "BELT" using by five workstations, each one being able to perform a set of...
Soil nitrogen availability in olive orchards after mulching legume cover crop r...
Rodrigues, M.A.; Correia, C.M.; Claro, Ana Marília; Ferreira, I.Q.; Barbosa, José Carlos; Moutinho-Pereira, J.M.; Bacelar, E.A.; Fernandes-Silva, A.A.A natural source of nitrogen (N) is needed to increase soil fertility in traditional olive orchards and to maintain the N nutritional status of olive trees. With this aim, we studied the introduction of legume cover crops in two olive orchards, which were converted into mulches and left on the ground as phytomass after they had been cut. The experiments were carried out in Suçães and Qta do Carrascal, NE Portug...

Rodrigues, M.A.; Pires, Jaime; Claro, Ana Marília; Ferreira, I.Q.; Barbosa, José Carlos; Arrobas, MargaridaA introdução de cobertos vegetais à base de leguminosas anuais de ressementeira natural em olival de sequeiro apresenta-se como uma forma aparentemente sustentável de gerir o solo, reduzindo o risco de erosão e promovendo a sua fertilidade. Contudo, como na grande maioria dos olivais tradicionais não existem presentemente animais em pastoreio, a persistência dos cobertos, nestes casos, tem de ser conseguida exc...
Flexible job shop scheduling problem in manufacturing
Curralo, Ana; Pereira, Ana I.; Barbosa, José; Leitão, PauloThis paper addresses a real assembly cell: the AIP-PRIMECA cell at the Université de Valenciennes et du Hainaut-Cambrésis, in France.

Flexible job shop scheduling problem in manufacturing
Curralo, Ana; Pereira, Ana I.; Barbosa, José; Leitão, PauloThis paper addresses a real flexible job shop problem, namely the AIP-PRIMECA Flexible Manufacturing System (FMS) located at the Université de Valenciennes et du Hainaut-Cambrésis.
Analisador de energia elétrica
Barbosa, José Manuel da SilvaNos dias que correm a energia elétrica tem uma importância crescente. Dispositivos com capacidade para caraterizar a energia elétrica que está a ser consumida no momento já começam a ser algo frequentes, tornando-os uma boa solução para caraterizar gastos energéticos. Os sinais adquiridos neste tipo de dispositivos, com capacidade de análise da energia da rede elétrica, têm características analógicas o que torn...
Contabilizando a reabilitação na avaliação de sustentabilidade de edifícios de ...
Barbosa, José Amarilio; Bragança, L.Este trabalho teve como objectivo o desenvolvimento de uma metodologia de avaliação de sustentabilidade direccionada para os edifícios de serviços. A metodologia será desenvolvida através da experiência adquirida na adaptação do sistema SBtool ao contexto português, que culminou no desenvolvimento da metodologia SBTool PT-H. Desta forma, a metodologia de avaliação de sustentabilidade de edifícios de serviços se...
Development of a sustainability assessment tool for office buildings
Barbosa, José Amarilio; Bragança, L.; Mateus, RicardoThe few available sustainability assessment tools applicable in Portugal are oriented for residential buildings. Nevertheless, the impacts of office buildings have been rising mainly due to an increase in the energy consumption for cooling and heating. This way, due to the growing environmental impact of office buildings, the development of Build-ing Sustainability Assessment (BSA) tools to assess the sustainab...
