A meningite neonatal é uma situação preocupante para o neonatologista, pois pode condicionar o desenvolvimento de importantes sequelas neurológicas e elevada mortalidade.O objectivo deste trabalho foi o de avaliar a incidência, morbilidade e mortalidade desta patologia na Unidade de Cuidados Intensivos Neonatais do Hospital de S. João.Os autores realizaram uma revisão dos processos clínicos dos recém-nascidos c...
Introdução: O pólen da família das Poaceae (gramíneas) é uma das principais fontes de aeroalergénios no mundo, particularmente na Europa Mediterrânica. Representa, por isso, um importante factor de risco de asma, rinite e/ou conjuntivite alérgica e constitui a principal causa de polinose em Portugal. Objectivo: Analisar a variação intradiária das concentrações de pólen de gramíneas na atmosfera das 5 estações d...
The main goal of this work is the characterization of the hyper-elastic mechanical behaviour of PDMS. The special specimens of PDMS (Sylgard® 184) were tested in a bi-axial tensile machine. The displacement and strain fields were measured using a commercial digital image correlation system (ARAMIS of GOM) during the tensile test. The experimental measurements are compared with numerical simulations, which use t...
The main goal of this work is to characterize the hyper-elastic mechanical behaviour of PDMS. For that, were made-up special specimens of PDMS (Sylgard® 184) for test them in bi-axial tensile machine. During the tensile test was used a commercial digital image correlation system (ARAMIS of GOM) to obtain de displacement and strain fields. These measurements are compared with numerical simulations which uses the...
This work presents the analysis of the displacement and strain fields at open hole carbon epoxy composite specimen using the optical of Digital Image Correlation (DIC). An uniaxial tensile test with Hexcel IM7/8552 composite specimen that was previous drilled and created a random intensity pattern on its surface. During the test was captured a sequence of images using an equipment of commercial DIC system, the ...

Diabetes is a widespread disease representing an enormous part of the total health costs. An early diagnostic could be of extremely importance both for the understanding and prevention of this pathology. Saliva is a fluid with increasing interest as a source of biomarkers for disease diagnostic and saliva protein composition changes have already been reported for diabetic individuals. However, the studies were ...
lhese resuíts show that Phl p 5 is prelerenlially associated with pollen grains, allhough a small percentage may also be lound in smaller partiele sizes. lt was recorded a yearly varialion in airlJorne pollen and Phl p 5. The highest polency pollen was recorded in 2009 bul the highesl load ln aeroallergen was registered in 2011. ln conclusion, aeroallergen quantification together wilh airborne pollen counts, ma...
These resulls show thal Ole e 1 is preferenlially associaled wilh pollen grains, allhough a small percenlage may also be found in submicronic particies. It was recorded a yeariy variation in airborne pollen and Ole e1. The highesl polency pollen and the highesl allergen index were recorded in 2010, a season wllh lhe lowesl pollen index. ln conclusion, aeroallergen quanlification may contribute togelher with air...
Wood is commonly used in residential combustion for heating purposes; however, it can be a major source of air pollutants, namely fine particles, volatile organic compounds and carbon monoxide. Since 2004, the PM10 daily limit value has been surpassed in Portugal, and the European Commission has stated that plans and programs must be designed in order to reduce these levels. In Portugal, 18% of PM10 emissions a...
