El estudio fue realizado mediante balances de energía y de masa, en cada componente de los sistemas de refrigeración y del sistema solar. La transferenc...
In this study, we analysed the structure and functioning of the Portuguese continental shelf ecosystem and investigated the role of sardine Sardina pilchardus using the Ecopath massbalance approach. An Ecopath model was configured to represent the continental shelf waters in the period 2006-2009. The model showed that biomass was concentrated in low and intermediate trophic levels as in other upwelling areas. S...

Os autores apresentam o caso clínico de uma criança de 5 anos, previamente saudável, que desde há 5 meses apresentava lesões cutâneas eritemato-vesiculo-bolhosas, recorrentes, interpretadas como impétigo bolhoso e medicada com antibioterapia geral, sem melhoria. A histologia demonstrou a existência de um descolamento dermo-epidérmico, contendo polimorfonucleares neutrófilos, eosinófilos e fibrina, e a imunofluo...
The exploitation of the common octopus Octopus vulgaris in Portugal increased 50% in the last 20 years, largely motivated by the depletion of many fish stocks. Recently, the biomass of this fishery resource sharply decreased in some areas causing serious concern among local fishermen and an effort is underway to advise on novel and sustainable management measures. In this context, the octopus pre-recruit aggreg...
