Effects of sewage pollution on the structure of rocky shore macroinvertebrate a...

Cabral-Oliveira, J.; Mendes, S.; Maranhão, P.; Pardal, M. A.

The urgency to find efficient indices and indicators to prevent further deterioration of coastal areas is one of the hot topics in today’s scientific publication. However, a detailed knowledge of community responses to anthropogenic impacts is essential to sustain those indices. The studies on the response of benthic community to sewage pollution on intertidal rocky shores are generally based on visual census a...

NOD2 gene mutations in ulcerative colitis: useless or misunderstood?

Freire, P; Cardoso, R; Figueiredo, P; Donato, MM; Ferreira, M; Mendes, S; Ferreira, AM; Vasconcelos, H; Portela, F; Sofia, C

PURPOSE: NOD2 mutations have been linked to an increased risk of Crohn's disease and to some of its phenotypes. The association between NOD2 mutations and susceptibility to ulcerative colitis (UC) remains somewhat controversial and potential correlations between these mutations and UC phenotype have not been studied. AIM: To assess whether NOD2 mutations are a risk factor for UC in Portugal and if there are any...

Sorption of lead (Pb2+) from aqueous solutions using chars obtained in the pyro...

Bernardo, Maria S.; Mendes, S.; Lapa, N.; Gonçalves, Margarida; Mendes, Benilde; Pinto, Filomena; Fonseca, I.

Carbonaceous solid products resulting from thermochemical processes (pyrolysis, gasification), commonly known as chars, are emerging as low-cost sorbents of metallic contaminants, being their effectiveness already demonstrated in several studies (Inyang et al., 2012; Fuente-Cuesta et al., 2012; Ko³odyñska et al., 2012; Quek and Balasubramanian, 2009; Devecia and Kar, 2013). Given the fact that the commercial v...

Monte Carlo Simulation of a Gamma Camera and Experimental Validation

M. C. Abreu; B. Tomé; N. Santos; P. Rato Mendes; S. Rodrigues

The purpose of this work was the Monte Carlo simulation of the Siemens E.Cam Dual Head Gamma Camera and consequent experimental validation, with the aim to further study and to improve the current understandingconcerning the operation of these systems, this way contributing to the development of detectors with betterenergy resolution, sensitivity, spatial resolution and linearity. The geometry and characteristi...
