Tomé, M. F.; Castelo, A.; Nóbrega, J. M.; Carneiro, O. S.; Paulo, G. S.; Pereira, F. T.This work employs numerical and experimental approaches to investigate three-dimensional container filling with Newtonian viscous fluids. For this purpose, a computer code developed for simulating three-dimensional free surface flows has been used. The CFD Freeflow3D code was specifically designed to deal with unsteady three-dimensional flows possessing multiple moving free surfaces. An experimental apparatus t...
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...
Comparing small-footprint lidar and forest inventory data for single strata bio...
Ferraz, A.; Gonçalves, G.; Soares, P; Tomé, M.; Mallet, C.; Jacquemoud, S.; Bretar, F.; Pereira, L.Current methods for accurately estimating vegetation biomass with remote sensing data require extensive, representative and time consuming field measurements to calibrate the sensor signal. In addition, such techniques focus on the topmost vegetation canopy and thus they are of little use over multi-layered forest ecosystems where the underneath strata hold considerable amounts of biomass. This work is the firs...
Sustained relief of obstructive symptoms for the remaining life of patients fol...
Canena, J; Liberato, M; Marques, I; Rodrigues, C; Lagos, A; Patrocínio, S; Tomé, M; Pires, E; Romão, C; Coutinho, A; Veiga, P; Neves, B; Deus, JRBACKGROUND: self-expanding metal stents are currently being used as a definitive palliative treatment for malignant colorectal obstruction in patients with incurable disease. Few studies have followed large numbers of patients from stent placement until death, and those few have reported conflicting results in the long-term clinical outcome data. AIMS: this study evaluated the clinical effectiveness of stent p...
Bio-Hydrogen production from glycerol by a strain of Enrerobacter aerogenes
Marques, Paula Alexandra; Bartolomeu, M. Lourdes; Tomé, M. Manuela; Neves, L. M.In this work, H2 production by a strain of Enterobacter aerogenes using as substrate pure glycerol and glycerol-containing biodiesel wastes was compared. The effect of physico-chemical parameters such as temperature, initial substrate and biomass concentrations on the bio-hydrogen production efficiency was investigated. The influence of the simultaneous removal of gases produced was also evaluated The results o...
Efeitos da lavoura profunda e da gradagem nas características do solo e na prod...
Madeira, M.; Azevedo, António; Soares, P.; Tomé, M.; Araújo, M. C.Instalou-se um sistema experimental, na região centro de Portugal (Rio Maior), para comparar o efeito de mobilização superficial (gradagem) e da mobilização profunda e contínua (lavoura) do solo no crescimento de Eucalyptus globulus e em características físico-químicas do solo, durante um período de onze anos, o qual é usual para a primeira rotação das plantações daquela espécie. A gradagem originou um decrésci...
