Life cycle assessment of two diets for finishing Bísaro boars - a case study to...

Martin, L.; Santos, A.; Amaral, F.; Silva, D.; Ressurreição, S.; Ramos, A.; Charneca, R.; Costa, F.; Marmelo, C.; Martins, J.M.

Improving animal feed efficiency to reduce Greenhouse Gas Emissions (GGE) is part of the support to be granted under the new Common Agricultural Policy Strategic Plan for Portugal. Pig producers do not have many alternatives to reduce the carbon footprint impact of their pork as the Feed Industry (FI) that supplies them still buys low-cost ingredients from the world market without considering their environmenta...


Modelo de otimização para um alimento composto de acabamento de suínos autócton...

Martin, L.; Ressureição, S.; Amaral, F.; Silva, D.; Marmelo, C.; Costa, F.; Ramos, A.; Charneca, R.; Martins, J.M.

A alimentação de suínos tem um custo significativo, mas para garantir a sustentabilidade da produção, há também que diminuir o impacte ambiental e promover a saúde. A formulação de um alimento composto (AC) é complexa. Neste trabalho pretendemos não só adequar as necessidades à disponibilidade de nutrientes, como minimizar custos e impacto ambiental. Recorremos à programação linear para encontrar um AC otimizad...


Introdução: Segurança humana e desenvolvimento nas relações UE-África

Seabra, P.; Amaral, F.

Nesta introdução estabelecemos os principais contornos do debate sobre as relações UE-África, com destaque para os desenvolvimentos institucionais mais recentes e para as ramificações mais significativas daí decorrentes ao nível da segurança humana e do nexo segurança-desenvolvimento. Numa primeira parte, procedemos à definição da problemática subjacente a esta temática, seguido de uma apresentação dos artigos ...

Electric and dielectric Behavior of Purified Galactomannan Films

Amaral, F.; Neto, Silva; Cavalcante, Lincoln; Santos, Adenilson; Graça, Manuel; Mendes, Fernando; Macêdo, Ana

This work aimed to extract, purify, and to characterize galactomannan from Adenanthera pavonina L. by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and impedance spectroscopy (IS).

Laser processing of CaMnO3-based materials for thermoelectric applications

Ferreira, N. M.; Amaral, F.; Madre, M. A.; Sotelo, A.; Kovalevsky, A. V.; Costa, F. M.

Today, a particular interest is given to the oxide-based thermoelectric materials, due to enhanced thermal and redox stability, attractive properties at high temperature, the absence of toxicity, and natural abundance of the constituent compounds. The objective of this work is to assess the possibilities for processing oxide thermoelectrics through laser floating zone (LFZ) method, including identification of t...


Investigation of micro- and nanoscale barrier layer capacitance mechanisms of c...

Ivanov, M.S.; Amaral, F.; Khomchenko, V. A.; Paixão, J. A.; Costa, L. C.

In this work we disclose micro- and nanoscale origins of the unusually high dielectric constant characteristic of CaCu3Ti4O12 (CCTO) ceramic by using the Scanning Probe Microscopy (SPM) technique. Two main mechanisms responsible for the colossal dielectric constant specific to the CCTO compound have been revealed. There is a microscale barrier layer capacitance (MBLC) mechanism, attributed to the potential grai...


Effects of agricultural practices on soil and microbial biomass carbon, nitroge...

Amaral, F.; Abelho, M.

In this study we assessed the C V N V P ratios in soil and soil microbial biomass subject to conventional farming and three different organic farming practices. The results showed that microbial biomass was P-limited in soils subject to conventional farming and to organic farming with alfalfa green manure. Organic farming with compost amendment showed the best results in terms of microbial biomass carbon, nitro...


Hybrid microwave processing of Ca3Co4O9 thermoelectrics

Miyazawa, K.; Amaral, F.; Kovalevsky, A. V.; Graca, M. P. F.

In this study, hybrid microwave sintering of Ca3Co4O9 thermoelectric materials was implemented for the first time. Thermoelectric properties of samples sintered in different conditions and in conventional electrical furnace, using the same temperatures and dwell times, were assessed and compared. Microwave processing was found to promote densification and grain texturing in Ca3Co4O9 bulk ceramics, leading to a ...
