Este trabalho teve como objetivo avaliar a adequação de dois métodos analíticos, o método de Olsen (Olsen-P) e o método de Egnér-Riehm (AL-P), na quantificação do fósforo(P) fitodisponível, após aplicação ao solo, num ensaio de campo, de resíduos orgânicos de pecuária como fertilizantes.
Comunicação oral da qual só está disponível o resumo. ; Phosphorus (P) is a non renewable resource which highlights the significance of developing and using alternative sources of P for a sustainable agriculture. Animal manure is an option but its application to soils to meet crop nitrogen needs requires careful management practices to minimize freshwater eutrophication. The aim of this work was to evaluate th...

Chemical-shift imaging (CSI) has been applied to the evaluation of patients with temporal lobe epilepsy (TLE), but few comparisons have been made between the data obtained from quantitative structural magnetic resonance imaging (MRI) and the accuracy of CSI to identify pathological changes within the hippocampus. Our goal was to determine the discriminative capability of CSI h...
Hippocampal sclerosis (HS) is a common lesion encountered in patients with temporal lobe epilepsy (TLE).Studies with quantitative magnetic resonance (MRI) and chemical-shift imaging (CSI) have found widespreadstructural and metabolic changes along the entire length of the hippocampus. The aim of this study was to investigate diffusion changes interictally in patients with chronic TLE ca...
This short communication provides a sporadic insight on the importance of a hard three-dimensional structure for deepwater fish near CWC. Fish size and behaviour inside the structure and in the surrounding area are described. Additionally, a list of biofouling macroorganisms found on the structure after one year of deployment is presented.
PTDC/AGR-PRO/112127/2009: Fitodisponibilidade e riscos ambientais do fósforo aplicado por via de chorumes de pecuária intensiva em solos portugueses. ; O conhecimento da partição do P no solo por diferentes formas com distinta labilidade, ajuda a perceber a dinâmica do P não só relativamente à sua fitodisponibilidade, como também a riscos de transferência para as águas com consequências negativas na eutrofizaç...

It was reported the occurrence of Spalangia endius Walker, 1839 (Hymenoptera, Pteromalidae) as a parasitoid of pupae of Musca domestica Linnaeus, 1758 (Diptera, Muscidae) and Stomoxys calcitrans Linnaeus, 1758 (Diptera, Muscidae) in the extreme Southern of Brazil. The collection of pupae was performed in January and February, 2008. The pupae of M. domestica and S. calcitrans were collected from bovine feces usi...
This study aimed to elucidate cortical mechanisms involved in anticipatory actions when 23 healthy right-handed subjects had to catch a free falling object through quantitative electroencephalogram (qEEG). For this reason, we used coherence that represents a measurement of linear covariation between two signals in the frequency domain. In addition, we investigated gamma-band (30-100 Hz) activity that is related...
