The main goal of this paper was to assess the greenhouse gas (GHG) intensity of olive oil production in Portugal. A life-cycle model and inventory were implemented for the entire production process, including a comprehensive analysis of olive cultivation, olive oil extraction, packaging, and distribution. Data originates from five differently-sized Portuguese olive growers and from a total of six olive oil mill...

No presente trabalho estudaram-se três métodos de avaliação do estado de Maturação da azeitona, baseados na coloração dos frutos das cultivares ‘Cobrançosa’ e ‘Galega Vulgar’ em estados precoces de maturação, bem como a sua relação com a acumulação de gordura. Os métodos estudados foram: IM – índice de maturação de Jaén (com 8 grupos de cor); IMS – índice de maturação simplificado com apenas três classes de co...
Realizaram-se ensaios de modelação e otimização das condições operatórias de extração de azeite, utilizando a metodologia das superfícies de resposta, segundo uma matriz central compósita rotativa, em função da concentração adicionada de adjuvantes na termobatedura – preparação enzimática Endozym Olea AS (0,04-0,24%) e microtalco FC8 (0,12-0,68%) – a um lote de azeitona Cobrançosa com um índice de maturação de ...
Yttria stabilized zirconia single crystal fibers doped with europium ions were developed envisaging optical applications. The laser floating zone technique was used in order to grow millimetric high quality single crystal fibers. The as-grown fibers are completely transparent and inclusion free, exhibiting a cubic structure. Under ultraviolet (UV) excitation, a broad emission band appears at 551 nm. The europiu...
Self-assembled GaN quantum dots (QDs) stacked in superlattices (SL) with AlN spacer layers were implanted with Europium ions to fluences of 1013, 1014, and 1015 cm−2. The damage level introduced in the QDs by the implantation stays well below that of thick GaN epilayers. For the lowest fluence, the structural properties remain unchanged after implantation and annealing while for higher fluences the implantation...
AlN films grown on sapphire were implanted with 300 keV Eu ions to fluences from 3×1014 to 1.4×1017 atoms/cm2 in two different geometries: “channeled” along the c-axis and “random” with a 10° angle between the ion beam and the surface normal. A detailed study of implantation damage accumulation is presented. Strong ion channeling effects are observed leading to significantly decreased damage levels for the chan...
Beekeeping offers a great development potential, as a source of food, as a nutritional complement and also as raw material provider to several activities. Moreover, biodiversity improvement conservation, incentive for retention of natural habitats and an ideal activity for forest conservation programmes are important factors associated with this activity. Honey is a natural sweet product that is produced in alm...
