Long-term monitoring of a mercury contaminated estuary (Ria de Aveiro, Portugal...

The main aim of this research was to assess the mercury transport from an estuarine basin with a background of anthropogenic contamination during a spring tidal cycle (year 2009) and compare it with two previous tidal cycles (years 1994 and 1999), as part of a long-term monitoring program. Results showed that effective mercury transport occurs both in the dissolved and particulate fractions (0.18 and 0.20 kg pe...

Peripheral nerve ultrasound – anatomy and technique for diagnosis and procedures

Relação entre o valor preditivo obtido através da avaliação da Escala de Morse ...

O presente artigo discute e reflecte os resultados obtidos através da análise de situações de queda, em contexto de internamento hospitalar, especificamente no serviço de internamento de cardiologia, relacionando as mesmas com a avaliação obtida na aplicação da escala de Quedas de Morse (EQM). A partir deste estudo, identificou-se que as características do serviço, e concretamente dos doentes que aí são interna...

Stability of LaNiO3 gas diffusion oxygen electrodes

In this work LaNiO3 perovskite-type oxide, prepared by a self-combustion method, was optimized for activity and stability as an anode material for water electrolysis. A full electrochemical study was conducted in order to kinetically characterize electrodes prepared using carbon paper as a base for porous gas-diffusion electrodes in alkaline media, regarding water oxidation and oxygen reduction reactions at roo...

Secondary traumatic stress disorder in war veterans’ adult offspring

The present study focuses on the impact of veteran’s traumatic stress and PTSD diagnosis on their offspring’s mental and physical health. Results revealed a positive relationship between PTSD in veterans and secondary traumatic stress disorder (STSD) in their offspring. STSD symptoms, psychopathology, physical symptoms and adverse childhood experiences were also positively related, especially, in those with STS...

Carbon based materials as novel redox mediators for dye wastewater biodegradation

Due to their large-scale production and extensive application, dyes have turned serious pollutants when improperly handled and disposed, creating grave public health and environmental problems. One of the problems that textile industry is facing is related with the incomplete exhaustion of dyes onto textile fibres from an aqueous dyeing process, and the need to implement innovative and sustainable effluent trea...

Immunoglobulin genes implicated in glioma risk

Both genetic and environmental factors are thought to be causal in gliomagenesis. Several genes have been implicated in glioma development, but the putative role of a major immunity-related gene complex member, immunoglobulin heavy chain γ (IGHG) has not been evaluated. Prior observations that IGHG-encoded γ marker (GM) allotypes exhibit differential sensitivity to an immunoevasion strategy of cytomegalovirus...

Imigração galega na cidade do Porto : 2ª metade do século XIX

Characterization and electrochemical behaviour of nanostructured calcium samari...

Ca1-xSmxMnO3(0 . x . 0.4) films were successfully fabricated on Indium Tin Oxide (ITO) coated quartzglass substrates by radio frequency magnetron sputtering technique (RF- magnetron sputtering) fromcompacted nanosized powder targets, and subsequent annealing at 800.C in air, for 6 h. X-ray diffrac-tion shows a pure typical perovskite phase for x . 0.1. Scanning electron microscopy and atomic forcemicroscopy r...

The role of strain localization in magma injection into a transtensional shear ...

This study deals with the interaction between deformation and magmatism in mid- to deep-crustal domains. The relation is analysed between migmatites and shear zones and the spatial distribution of leucogranitoid veins and dykes running through a footwall migmatite system, and reaching a transtensional shear zone operated under amphibolite- to greenschist-facies metamorphic conditions (Boa Fé shear zone, Varisca...
