Emissão de compostos orgânicos voláteis (COV) em produtos da construção

Os revestimentos de parede, as tintas, os adesivos ou os materiais à base de madeira, podem emitir formaldeído e outros compostos orgânicos voláteis (COV), que estão muitas vezes associados a problemas de saúde e de bem-estar no interior dos edifícios. Segundo o requisito básico número três, Higiene, Saúde e Ambiente, do Regulamento dos Produtos de Construção (CPR, 305/2011), “as obras de construção devem ser c...

Isolation of clinical strains of Staphylococcus epidermidis from a Portuguese h...

Staphylococcus epidermidis has been documented as an emergent pathogen responsible for many healthcareassociated infections (HAIs). These infections are an increasing cause of major concern not only due to the high distribution of methicillin resistance, but also due to their ability to form biofilm, which increases their persistence, impairs patient’s quality of life and leads to failed treatment and extra cos...

Rapid detection of urinary tract infections caused by Proteus spp. using PNA-FISH

We developed a fluorescence in situ hybridization (FISH) method for the rapid detection of Proteus spp. in urine, using a novel peptide nucleic acid (PNA) probe. Testing on 137 urine samples from patients with urinary tract infections has shown specificity and sensitivity values of 98 % (95 % CI, 93.2–99.7) and 100 % (95 % CI, 80,8–100), respectively, when compared with CHROMagar Orientation medium. Results ind...

Genotypic and phenotypic differences between nosocomial and commensal Staphyloc...

Staphylococcus epidermidis is a common causative agent of relapsing and persistent hospital-acquired infections, not only because this bacterium belongs to the patients’ microbiota(causing autoinfection) but also because it is easily transmitted by healthcare workers (causing cross-infections). The goal of the present study was to characterize, for the first time, the biofilm-forming ability and virulence assoc...

Accessibility disruptions in urban areas caused by extreme rainfall events

Due to the increased frequency of extreme events caused by climate change, flooding in urban areas are becoming increasingly frequent. The village of Agualva, located in Terceira Island (Azores, Portugal), suffered a severe flood on the early morning of 15th of December 2009 caused by a short-duration and extreme intensity rainfall event. This village lies on the downstream part of the basin of the Ribeira da A...

Analisador paramétrico de transístores com controlo de temperatura

Neste documento é descrito um analisador de características estáticas de transístores de junção bipolar cuja temperatura da cápsula do transístor em teste pode ser controlada, constituindo assim um dos parâmetros de análise. O analisador foi desenvolvido para suprir a necessidade de demonstração em aulas laboratoriais da dependência com a temperatura de algumas características estáticas dos transístores bipolar...
