Este trabalho de investigação pretende estudar o efeito da incorporação de fibras de resíduos da indústria têxtil nas argamassas de reboco e auscultar o potencial deste material compósito. Neste caso, os resíduos da indústria têxtil considerados são fios ou pedaços de tecido ou malhas, e poderão ter uma grande variabilidade material (e.g. composição, espessura, densidade, entre outras). Aspectos relacionados co...

Apresentamos o caso de um homem de 21 anos, que foi submetido a apendicectomia sob anestesia geral e que imediatamente após a extubação desencadeou quadro de edema putmonar agudo. A propósito, faremos uma breve revisão da literatura, enfatizando os mecanismos fisiopatotógicos subjacentes e os aspectos mais importantes do diagnóstico e tratamento.
OBJECTIVE: To evaluate the frequency of non-alcoholic fatty liver disease (NAFLD) in patients with type 2 diabetes mellitus (DM2) and to describe its risk factors. SUBJECTS AND METHODS: Blood samples of 78 patients were collected for assessment of glycemic and lipid profile, liver enzymes, TNF-α and HOMA-IR. The diagnosis of NAFLD was established by ultrasound. RESULTS: NAFLD was observed in 42% of patient...
The aim of this work was to determine the dioctyl azelate (DOZ) plasticizer diffusion coefficient (D) for samples containing the interfaces of rubber, liner and solid composite propellant based on hydroxyl-terminated polybutadiene (HTPB). The samples used in the diffusion study were aged up to 31 days after the cure period at 80 °C. A computer program implementing a mathematical model of Fick's second Law of di...
The main objective of this study was to determine the geometry of the FIP, in the Castelo Branco granite massif. This study showed that in addition to FIP in Mode I, are also present Mode II, suggesting that the directions found NE-SW to NNE-SSW and E-W to ESE-WNW can be interpreted as related to a maximum stress (σ1) oriented NE-SW. The NNW-SSE orientation corresponds to a late system
Avaliaram-se os efeitos da geleia real sobre os parâmetros morfofisiológicos testiculares de camundongos (Mus musculus). Utilizaram-se 57 machos Swiss, com quatro meses de idade, distribuídos aleatoriamente em seis tratamentos: T1: solução fisiológica, via intraperitoneal; T2: 0,1mg de geleia real, via intraperitoneal; T3: 0,2mg de geleia real, via intraperitoneal; T4: água destilada, via oral; T5: 0,1mg de gel...
An electronic tongue with 36 cross-sensibility polymeric membranes was built and used for semi-quantitative analysis of beverages. The objective was to differentiate 4 non-alcoholic beverage groups with different added fruit juice contents: higher than 30%, between 14%-30%, 5%-10% and 0.1%-2%. A set of 16 Portuguese beverages (4 for each group), purchased in commercial supermarkets, was analyzed and the respect...
An electronic tongue with 36 cross-sensibility polymeric membranes was built and applied for qualitative beverage analysis. ; An electronic tongue with 36 cross-sensibility polymeric membranes was built and applied for qualitative beverage analysis. The objective was to distinguish non-a1coholic beverages with different leveis of added fruit juice. The different signal profiles recorded by the electronic tongu...
