European landscapes are under enormous pressures related to the major challenges facing our society. In our research we intend to analyze recent landscape change in the Alqueva dam watershed and predict future scenarios in terms of land use/cover and landscape configuration. The multi-agent systems modeling of land use/cover change (MAS/LUCC) are tools that combine methods like multi-criteria evaluation (MCE) and cellular automata (CA), being able to go beyond the mere analysis of land ...

The main goal of this work is to present a numerical model to assess the fire safety of wooden slabs with rectangular perforations at the ceiling. These typical constructions have good sound absorption, heat insulation and relevant architectonic characteristics. They are used in many civil applications: concert and conference halls, classrooms, nurseries, airports, hotels, shopping, universities, and many other public buildings. These panels are normally installed at lower level in building c...

Honey is natural sweet substance produced by Apis mellifera, which is consumed as a high nutritive value food. The physicochemical quality criteria of honey are well specified by the European Legislation (EC Directive 2001/110) [1]. The quality properties of honey can be diminished by the influence of heating in the thermal pasteurization of honey [2]. As an alternative to conventional thermal pasteurization, the non-thermal high pressure processing has potential to produce safety...

No nosso País o ensino experimental das ciências tem algumas dificuldades tendo em conta fraca formação nesta área e também os escassos recursos laboratoriais nas escolas. Estudos recentes no âmbito do ensino-aprendizagem das Ciências, reconhecem que é fundamental a construção da literacia científica dos cidadãos e o desenvolvimento de atitudes e competências de carácter transversal. As atividades experimentais facilitam a interação entre os alunos, promovem o desenvolviment...

The antioxidant properties of almond green husks (Cvs. Duro Italiano, Ferraduel, Ferranhês, Ferrastar and Orelha de Mula), chestnut skins and chestnut leaves (Cvs. Aveleira, Boa Ventura, Judia and Longal) were evaluated through several chemical and biochemical assays in order to provide a novel strategy to stimulate the application of waste products as new suppliers of useful bioactive compounds, namely antioxidants. All the assayed by-products revealed good antioxidant properties, with very ...
