Mandible anomalies—how can two-dimensional ultrasound help?

Mandible anomalies are congenital facial defects commonly referred in several syndromes, chromosomal and genetic conditions. This anomalies can be associated with profile defects, feeding and breathing disabilities after birth. Prenatal diagnosis of mandible anomalies by two-dimensional ultrasound is possible and relevant for an early posterior management. Different approaches for biometric measurement of fetal...

Diagnóstico Prénatal de Hemocromatose Neonatal: Será possível?

Introdução: A Hemocromatose Neonatal é uma doença hepática rara de início intrauterino, definida por insuficiência hepática neonatal associada a siderose extra-hepática. A doença hepática gestacional aloimune foi estabelecida como causa da lesão hepática fetal. Atualmente, não existe uma abordagem eficaz para o diagnóstico prénatal. Caso Clínico: Grávida de 23 anos apresentou às 32 semanas de gestação oligohidr...

Macroscopic and histopathological study of the placenta: an essential resource ...

The pathological study of the placenta is of upmost importance in cases of unexplained fetal/perinatal loss and often these carry litigation implications. Integrating pathological findings and the underlying pathophysiological processes, leading to placental lesions, is fundamental for the evaluation of poor fetal and perinatal outcomes and to distinguish from cases of true negligence.

Water-use strategies in two co-occurring Mediterranean evergreen oaks: survivin...

In the Mediterranean evergreen oakwoodlands of southern Portugal, the main tree species are Quercus ilex ssp. rotundifolia Lam. (holm oak) and Quercus suber L. (cork oak). We studied a savannah-type woodland where these species coexist, with the aim of better understanding the mechanisms of tree adaptation to seasonal drought. In both species, seasonal variations in transpiration and predawn leaf water potentia...

Modelling interception loss from evergreen oak Mediterranean savannas: applicat...

In a previous study, it was shown that an isolated, fully saturated tree-crown behaves like a wet bulb, allowing evaporation of intercepted rainfall to be estimated by a simple diffusion equation for water vapour. This observation was taken as the basis for a new approach in modelling interception loss fromsavanna-type woodland, whereby the ecosystem evaporation is derived by scaling up the evaporation from ind...

Evaporation of intercepted rainfall from isolated evergreen oak trees: do the c...

A new approach is suggested for estimating evaporation of intercepted rainfall from single trees in sparse forests. It is shown that, theoretically, the surface temperature of a wet tree crown will depend on the available energy and windspeed. But for a fully saturated canopy under rainy conditions, surface temperature will approach the wet bulb temperature when available energy tends to zero. This was confirme...

Evapotranspiration from a Mediterranean evergreen oak savannah: The role of tre...

Mediterranean evergreen oak woodlands of southern Portugal (montados) are savannah-type ecosystems with a widely sparse tree cover, over extensive grassland. Therefore, ecosystem water fluxes derive from two quite differentiated sources: the trees and the pasture. Partitioning of fluxes according to these different sources is necessary to quantify overall ecosystem water losses as well as to improve knowledge o...

A review of rainfall interception modelling

This paper is a review of physically-based rainfall interception modelling. Fifteen models were selected, representing distinct concepts of the interception process. Applications of these models to field data sets published before March 2008 are also analysed. We review the theoretical basis of the different models, and give an overview of the models’ characteristics. The review is designed to help with the dec...
