The COVID -19 pandemic dramatically affected people's lives. In this study, we explored the role of social and personal factors underlying individuals' adaptive responses during the critical onset period of the outbreak. In particular, we tested two models on the mediating role of health-protective behaviors in the relationship between social support, resilience, and helping behavior. A sample of 1085 participa...
Background: An outbreak of Legionella pneumophila serogroup 1, with 403 cases was identified on the 7th November 2014 in Vila Franca de Xira, Portugal. Outbreak source was the wet cooling system of a local factory. Hospital Pulido Valente was one of the hospitals receiving patients with Legionnaires’ disease (LD). Methods: We describe the clinical findings and diagnostic methods used among the 43 confirmed or p...

Background - For dose reduction actions, the principle of “image quality as good as possible” to “image quality as good as needed” requires to know whether the physical measures and visual image quality relate. Visual evaluation and objective physical measures of image quality can appear to be different. If there is no noticeable effect on the visual image quality with a low dose but there is a objective physic...
Purpose: To evaluate if physical measures of noise predict image quality at high and low noise levels. Method: Twenty-four images were acquired on a DR system using a Pehamed DIGRAD phantom at three kVp settings (60, 70 and 81) across a range of mAs values. The image acquisition setup consisted of 14 cm of PMMA slabs with the phantom placed in the middle at 120 cm SID. Signal-to-noise ratio (SNR) and Contrast-t...
A avaliação do estado redox plasmático, que consiste na determinação simultânea das concentrações plasmáticas de lactato, piruvato, acetoacetato e P-hidroxibutirato, é útil no rastreio das doenças hereditárias do metabolismo por défice energético. O seu doseamento exige rigorosas condições de colheita e processamento das amostras. Fez-se o estudo de 70 crianças sem doença metabólica com idades compreendidas ent...
Carcinus maenas, the common shore crab of European coastal waters, has recently gained notoriety due to its globally invasive nature associated with drastic ecological and economic effects. The native ubiquity and worldwide importance of C. maenas has resulted in it becoming one of the best-studied estuarine crustacean species globally. Accordingly, there is significant interest in investigating the population ...

No âmbito do projecto “Construção com Formação”, no qual se pretende construir uma nova escola na missão de Camabatela, na província do Kwanza Norte, em Angola, fazendo uso dos materiais e técnicas de construção correntes no local, foram realizados ensaios de caracterização dos adobes produzidos localmente, e dos solos utilizados na sua produção e na própria construção, em argamassas e rebocos. Devido aos limit...
