Deep geological processes, such as the removal of the thermal boundary layer or detachment of the lithospheric mantle, were crucial to sustain a large-scale high thermal regime during the Variscan orogeny. The genesis and emplacement of voluminous granitoid rocks represent the main effect of an HT-event related to that thermal regime, peaking at ca. 340-325 Ma but remaining high enough for several Ma; as a resu...
In order to build up a forensic database with the characteristics of the sediments and soils of the Portuguese mainland hundreds of beach and dune sediment samples were collected. The samples have been analyzed by several analytical techniques and several studies were undertaken to assess which are the properties best suited to the discrimination between areas and samples
Sistemas de irrigação localizada são conhecidos pela economia no consumo de água. No entanto, por ser um sistema de rede fixa, os custos de instalação e de operação tendem a ser elevados e sua utilização inibida. O presente trabalho teve como objetivo principal otimizar redes de distribuição de água para irrigação localizada, frente a diferentes configurações de declividade do terreno (0% a 5%) e tarifação de e...
Information on nutrient demand during each growth stage is essential for efficient application of nutrients. A pot experiment was carried out with a Typic Hapludox under greenhouse conditions in Botucatu, SP, Brazil, aiming was to determine nutrient uptake and partition of sweet pepper plants, cultivar Elisa in randomized block design with four replications. The fertigation was simulated through 2-L PET bottles...
