Necrotizing Faciitis after shoulder mobilization and intra-articular infiltrati...

Necrotizing Fasciitis is a rapidly progressive, potentially fatal infection of superficial fasciae and subcutaneous tissue, usually resulting from an inciting trauma to the skin. Medical literature refers few cases of necrotizing fasciitis related to intra-articular infiltrations, that often lead to patients death. This report describes the clinical events on a 55 year-old diabetic patient who developed upper e...

Estratégias Cirúrgicas em Fracturas do Osso Frágil

O problema principal no tratamento de fracturas em osso frágil é a fixação óssea dos diversos tipos de implantes. As placas com parafuso deslizante, as cavilhas endomedulares e o efeito em banda de tensão, encontram nestas situações traumáticas a sua melhor indicação, por a forma a maximizar a compressão óssea e diminuir a tensão na interface osso-implante. Para além disso, a vertebroplastia e a cifoplastia têm...

Study of Nα-benzoyl-L-argininate ethyl ester chloride, a model compound for pol...

Poly(ester amide)s (PEAs) are lacking in structural and spectroscopic information. This paper reports a structural and spectroscopic characterization of Nα-benzoyl-L-argininate ethyl ester chloride (BAEEH+·Cl−), an important amino acid derivative and an adequate PEAs’ model compound. Crystals of BAEEH+·Cl− obtained by slow evaporation in an ethanol/water mixture were studied by different complementary technique...

Viabilidade ambiental das hortas urbanas enquanto espaços para o desenvolviment...

As hortas urbanas constituem espaços de usos múltiplos, en- quanto espaços verdes, espaços de alimentação, espaços de econo- mia e espaços de recreio e lazer, fundamentais ao desenvolvimento de qualquer cidade que se pretenda sustentável. Como forma de avaliar a viabilidade ambiental das hortas urbanas da cidade de Braga foram realizadas análises a amostras de alfaces e de solos. Os resultados analít...

Zircon typologies and internal structures as petrogenetic indicators in contras...

The aim of the present morphological zircon study is to characterize the sources reservoirs involved in the generation of the different type of granites, testing the classic ‘Pupin method’ and zircon geochemistry against the petrogenetic indications given by geochemical and isotopic data. In northern Portugal large volumes of granitoids were emplaced during the last stage (D3) of the Variscan orogeny and displa...

Geocronologia e petrogénese do plutonismo tardi-varisco, NW de Portugal : sínte...

No NW de Portugal ocorre um importante volume de granitóides, que correspondem a sucessivos pulsos magmáticos principalmente instalados na etapa pós-colisional da orogenia varisca (290-321 Ma). Trata-se de plutonismo com assinaturas químicas e isotópicas diversas e forte variabilidade composicional. No presente trabalho, apresenta-se uma síntese dos dados geocronológicos e petrogenéticos disponíveis e discut...

Geochronology and petrogenesis of late-Variscan plutonism, NW Portugal : synthe...

Geochronology and petrogenesis of late-Variscan plutonism (NW Portugal) : synth...

In NW Portugal large volumes of granitoids were emplaced during the post-collisional stage of the Variscan orogeny. This was the main period of successive granite generation, which exhibit different chemical and isotopic signatures. Geochronological and petrogenetic results are presented and inferences on the geodynamic evolution of the Iberian Variscides are discussed.

Low-Temperature FTIR Spectroscopic and Theoretical Study on an Energetic Nitroi...

This paper presents an overview of recent progress in spectroscopic studies of the energetic nitroimine 4,6-bis(nitroimino)-1,3,5-triazinan-2-one (DNAM), based on experimental and theoretical data. The following topics are considered: variable temperature FTIR spectroscopy (4000−400 cm-1) applied to the study of natural and isotopically substituted (deuterated) samples aiming to obtain a successful vibrational...
