Carbon balance estimation for agroforestry land use alternatives in Portugal
Crous-Duran, J.; Paulo, J.A.; Palma, J.H.N.Poster ; In 2005, 11% of the anthropogenic greenhouse gases emissions (GHG) were originated from agricultural activities and this value is expected to increase in the future. Besides the contribution for the restoration of soil productivity and for the improvement of conditions in degraded land, Agroforestry is also proposed as one of the main solutions for the mitigation of the GHG emissions and their effect ...
Innovating tree plantation design: spiralographing agroforestry
Palma, J.H.N.; Crous-Duran, J.; Merouani, H.; Paulo, J.A.; Tomé, M.Poster ; Most of forestry or agroforestry artificial plantations either have an orthogonal design, or curvilinear under contour lines to prevent soil erosion. These designs are known to maximize machinery workflow or erosion control respectively. As in many occasions in land use management, what optimizes machinery operation is not what optimizes prevention of soil loss and vice versa. An alternative and int...

Holistic agroforestry system in practice. Just an idea or is there a living mod...
Palma, J.H.N.; Paulo, J.A.; Sendim, A.Presentation ; In the last decades there has been a tendency to classify agroforestry systems to help focus on particular aspects of different practices with specific objectives. However, in practice, the management of land use at farm scale has a wide range of options and decisions to be made at operational level following a certain strategy. Farmers can adopt certain agroforestry practices to suit and enhan...
VIBRATIONAL SPECTROSCOPY (FTIR-ATR AND FT-RAMAN) - A Rapid and Useful Tool for ...
Pereira, Leonel; Amado, Ana M.; Ribeiro-Claro, Paulo J. A.; van de Velde, FredThe wide industrial application of phycocolloids (e.g. alginates, agar and carrageenans) is based on their particular properties to form gels in aqueous solution. Recently, new spectroscopic techniques have provided more accurate identification of the natural composition of the polysaccharides produced by these seaweeds. With the combination of two spectroscopic techniques (FTIR-ATR and FT-Raman) it is possible...

Hubinger,Míriam D.; Vivanco-Pezantes,David; Kurozawa,Louise E.; Sobral,Paulo J. A.O presente trabalho teve como objetivo a obtenção de isotermas de dessorção de filés de bonito (Sarda sarda), previamente salgados a vácuo e defumados com fumaça líquida. As isotermas foram obtidas a quatro temperaturas (5, 25, 40 e 60 ºC) em condições de dessorção, através do método gravimétrico estático, com soluções salinas saturadas. Os dados experimentais foram ajustados a quatro modelos da literatura (BET...
