Vulnerability assessment of urban building stock: a hierarchic approach

In the last decades the evaluation of the seismic risk are of rising concern, considered essential in the activity and definition of strategy planning and urban management. The evaluation of the seismic vulnerability of the existent building stock in the perspective of the seismic risk mitigation should not be placed only in relation to the isolated buildings of relevant historical and cultural importance, but ...

Seismic vulnerability assessment of the old city centre of Seixal, Portugal

The seismic vulnerability assessment of old traditional masonry building stocks, in a seismic risk mitigation perspective, is truly essential not only for buildings with recognized historical and patrimonial value, but also, in relation to regular buildings. In this sense, this paper approaches the issue of the seismic vulnerability assessment of masonry buildings through the application of a simplified methodo...

Tipos habitacionais e estratégias de reabilitação do núcleo urbano antigo do Se...

Os núcleos urbanos antigos são portadores de um património histórico e arquitectónico a proteger e a potenciar. Para tal, é necessário compreender a sua génese, tanto no plano do edifício como no plano do conjunto urbano. Deste modo, considera-se importante o estudo do edificado como apoio a intervenções de reabilitação qualificadas, conscientes e sustentáveis. Este artigo aborda o assunto dos núcleos urbanos a...

Evaluation of strengthening techniques of traditional masonry buildings: case s...

Increasing appraisal of the durability, conservation state, and changeable use and function of old buildings in urban centers relies a great deal on the structural safety evaluation of vertical load capacity and the ability to resist horizontal forces. The need to assess seismic vulnerability, particularly of traditional masonry buildings, is a key issue. Evaluation of the seismic vulnerability of old buildings...

Electrospun nanofibrous mats: outstanding materials for biotechnology applications

Avaliação da vulnerabilidade de edifícios antigos e do risco sísmico à escala d...

Nas últimas décadas, a avaliação do risco sísmico é de preocupação crescente, considerada essencial na actividade e definição de estratégias de planeamento e gestão urbana. A avaliação da vulnerabilidade sísmica dos edifícios existentes na perspectiva da mitigação do risco sísmico deve colocar-se não só em relação aos edifícios isolados de relevante importância histórica, mas também em relação aos aglomerados d...

BioRePortAP, an electronic clinical record coupled with a database : an example...

Aims: To evaluate the efficacy and safety of the treatment of psoriatic arthritis (PsA) patients with tumor necrosis factor (TNF) antagonists in the Rheumatology Department of Hospital de Santa Maria using the BioRePortAP. Methods: The Portuguese Society of Rheumatology (SPR) developed an electronic medical chart coupled with a database for the follow up of PsA patients, the BioRePortAP, which was launched in ...

Estimation of RF PA Non-Linearities After Cross-Correlating Current and Output ...

The estimation of 1 dB compression and third-order intercept points can be obtained after the cross-correlation between dynamic current and output voltage of radio frequency power amplifiers. This estimation is performed using actual power measures and not power inferred from voltage measurements. The underlining theory and a correlator that allows implementing this measurement on-chip are presented. The trade-...

High pressure treatments as an alternative to conventional thermal blanching - ...

The effect of pressure treatments of 100 and 200MPa (10 and 20min) and thermal blanching at 70°C, 80°C and 98°C (1 and 2.5min), on green and red sweet bell peppers was compared. Pressure treated peppers showed a lower reduction on soluble protein and ascorbic acid contents (red peppers presented even an increased content of ascorbic acid of about 15-20%). Peroxidase (POD) and pectin methylesterase (PME) (whose ...

Desenvolvimento de tecnologias para a redução do teor de sulfuroso em vinhos

A adição de sulfuroso nas diferentes etapas de vinificação tem por objectivo impedir o crescimento microbiológico de espécies nocivas ao vinho, assim como actuar como antioxidante, mantendo as características sensoriais do vinho. Contudo, os produtores têm procurado reduzir a utilização de sulfuroso dada a sensibilidade alérgica a este composto por cerca de um terço dos consumidores. Neste trabalho, testaram-se...
