A mathematical model for non-catalytic liquid-solid reversible reactions
Pais, F. I. C. C.; Portugal, A. A. T. G.A sharp interface model has been developed for non-catalytic liquid-solid reversible reactions. It is shown that a sharp reaction interface can occur, in certain circumstances, even if the reaction is reversible. Because the pseudosteady state approximation may not be valid for liquid-solid reactions, this assumption was not made in the model. This led to the need for numerical resolution and the model was solv...
The transesophageal echocardiogram in the evaluation of cerebrovascular diseases.
Pinto, A N; Serviço de Neurologia, UTIC-Arsénio Cordeiro, Hospital de Santa Maria, Lisboa.; Ferro, J M; Sá, A B; Pais, FWe evaluated the diagnostic sensitivity and clinical value of transesophageal echocardiogram in 72 patients with a potential cardiogenic embolic stroke or transient ischemic attacks at the Neurological Department/Cerebrovascular disorders out-patient clinic of Santa Maria Hospital between February 1991 - February 1993. The transesophageal echocardiogram was performed in UTIC-Arsénio Cordeiro after current diagn...
