“Paio do Alentejo” is a Portuguese dry-cured sausage, made with meat from the Alentejano pig breed. The main aim of this study is to evaluate the benefits of the use of starter cultures on the quality of the sausage, mainly with regard to its sensory properties, rheological characteristics and PAH profile. Three batches of the product were examined: S1-inoculated with a commercial starter comprising Lactobacill...
Pseudoaneurysms of the ascending aorta are a rare complication of cardiac surgery. However, the poor prognosis associated with this condition if untreated makes early diagnosis and treatment important. We present the case of a 66-year-old woman who had undergone mitral valvuloplasty 12 days previously, who was admitted with a diagnosis of new-onset atrial fibrillation. The transthoracic echocardiogram showed a ...
O síndrome da morte súbita, inesperada e inexplicada do lactente (MSIL) ocorre normalmente entre 1M e 1 A de vida, com um máximo entre os 2 e os 4M, constituindo a principal causa de morte pós-neonatal nos países desenvolvidos.A MSIL ocorre quase sempre no domicílio e constitui em geral um achado isolado numa família, embora ocasionalmente se repita em irmãos. Em Portugal foi já observada uma família com 6 caso...
Só está disponível resumo. ; Morphological, mechanical, and optical properties of cypress papers.
A total of 120 Acacia melanoxylon R. Br. (Australian blackwood) stem discs, belonging to 20 trees from four sites in Portugal, were used in this study. The samples were kraft pulped under standard identical conditions targeted to a Kappa number of 15. A Near Infrared (NIR) partial least squares regression (PLSR) model was developed for the Kappa number prediction using 75 pulp samples with a narrow Kappa number...
Wood samples of Cupressus arizonica, C. lusitanica, and C. sempervirens were evaluated for chemical, anatomical, and pulp characteristics as raw material for pulp production. Two 17-year-old trees per species were harvested, and wood samples were taken at a height of 2 m. Wood chips from Pinus pinaster (Portugal) and P. sylvestris (Finland) were used as references. C. arizonica differed from C. lusitanica and C...
Os autores fazem a análise dos doentes submetidos a ventilação mecânica na Unidade de Cuidados Intensivos Pediátricos do Hospital de Dona Estefânia, num período de 33 meses, desde a sua abertura em Abril de 1991 até ao final de Dezembro de 1993.Neste período foram internadas na Unidade 1513 crianças, das quais 264 (17.4%) foram ventiladas.A idade dos doentes ventilados variou entre os 28 dias e os 15 anos (médi...
The Pinhal do Souto mine exploited a quartz vein containing uranium minerals, mainly autunite and torbernite. This vein intersects a two-mica granite containing 10 ppm U and uraninite. The mine was exploited underground and produced 93,091 kg U3O8 between 1978 and 1989 and was then closed down. Two dumps were left in the mine area and these are partially covered by natural vegetation. Groundwater and surface wa...
The Metabolic Syndrome increases the risk for atherosclerotic cardiovascular disease and type 2 Diabetes Mellitus. Increased fructose consumption and/or mineral deficiency have been associated with Metabolic Syndrome development. This study aimed to investigate the effects of 8 weeks consumption of a hypersaline sodium-rich naturally sparkling mineral water on 10% fructose-fed Sprague-Dawley rats (Metabolic Syn...
A comutação das propriedades ópticas não-lineares (NLO) é de grande interesse na área da optoelectrónica e fotónica. O conceito de comutação molecular com base nas propriedades de NLO baseia-se na possibilidade de conseguir uma mudança na resposta óptica não linear entre duas formas ('on' e 'off'), desde que essas duas formas moleculares possuam uma grande diferença na magnitude das respectivas hiperpolarizabil...
