Foram estudados restrospectivamente 39 casos de Coartação da Aorta isolada ou associada a outras anomalias cardíacas, diagnosticadas no primeiro ano de vida e internados na Unidade de Cardiologia Pediátrica do Hospital de Santa Maria e Hospital de Santa Cruz entre 1981 e 1990.Os parâmetros analisados foram: idade de diagnóstico, distribuição por sexos, forma clínica de apresentação, tipo anatómico, presença ou ...
Introdução: A empatia é um conceito multi- dimensional que engloba a capacidade de in- ferir um estado emocional e responder a emo- ções vivenciadas pelo outro, podendo ser assim categorizada em empatia cognitiva e emocional. É uma capacidade que se desenvolve pre- cocemente através, sobretudo, da interação com as figuras parentais. Não é exclusiva dos seres humanos e tem sido conservada evolutivamente, c...
O estigma da doença mental tem sido alvo de crescente atenção nos últimos anos, com um aumento exponencial de publicações sobre o tema. Este fenómeno constitui para os doen- tes uma fonte de sofrimento, representando um obstáculo à concretização de projectos pessoais e à integração social plena, objectivo principal da prática psiquiátrica actual. Neste artigo, os autores fazem uma revisão selec...
A new water soluble fluorene-based polyelectrolyte containing on-chain porphyrin units has been synthesized via Suzuki coupling, for use in optoelectronic devices. The material consist of a random copolymer of poly{1,4-phenylene-[9,9-bis(4-phenoxy butylsulfonate)]fluorene-2,7-diyl} (PBS-PFP) and a 5,15-diphenylporphyrin (DPP). The energy transfer process between the PBS-PFP units and the porphyrin has been inve...
Cyclic load reversals (like those induced by earthquakes) result in accelerated bond degradation, leading to significant bar slippage. The bond-slip mechanism is reported to be one of the most common causes of damage and even collapse of existing RC structures subjected to earthquake loading. RC structures with plain reinforcing bars, designed and built prior to the enforcement of the modern seismic-oriented de...
Existing reinforced concrete (RC) buildings constructed until the mid-70’s, with plain reinforcing bars, are expected to behave poorly when subjected to earthquake actions. This paper describes an experimental program designed to investigate the influence of poor detailing on the cyclic behaviour of RC beam-column joint elements. Cyclic tests were performed on five interior and five exterior full-scale beam-col...
A large number of existing reinforced concrete (RC) buildings structures were designed and built before mid-70’s, when the reinforcing bars had plain surface and prior to the enforcement of the modern seismic-oriented design philosophies. This paper describes a series of unidirectional cyclic tests performed on seven full-scale columns built with plain reinforcing bars, without adequate reinforcement detailing ...
The information available in the literature about the cyclic behaviour of reinforced concrete elements with plain reinforcing bars is scarce. As a consequence, the influence of bar slippage in elements with plain bars is not yet comprehensively understood. In this paper are presented and discussed the main results of the cyclic tests carried out on five full-scale reinforced concrete beam-column joints with pla...
An experimental program was carried out to analyse the potentialities of a technique based on the use of multidirectional CFRP laminates (MDL-CFRP) for the seismic repair and strengthening of reinforced concrete (RC) beam-column joints. This experimental program comprises cyclic tests on three full-scale RC joints, representative of interior beam-column connections in buildings. The joints were initially submit...
Coriandrum sativum L. (Umbelliferae), conhecido popularmente por coentro, é uma planta doméstica cultivada nas diversas partes do mundo, inclusive no Brasil. As folhas e frutos do coentro são utilizados como condimento em culinária e na medicina popular como analgésica, antirreumática, carminativa e colagoga. O objetivo deste estudo foi avaliar o efeito do tratamento com o óleo essencial (OEC) e o extrato hidro...
