Relatório de estágio de mestrado em Ensino do Português no 3º Ciclo do Ensino Básico e Ensino Secundário e do Espanhol nos Ensinos Básico e Secundário ; O presente relatório tem a finalidade de registar o trabalho desenvolvido num projeto de intervenção pedagógica supervisionada, cujo principal objetivo foi o desenvolvimento da competência de escrita numa turma de Português do 11º ano, e da oralidade numa turm...
A presente investigação parte do pressuposto de que a existência de conciliação da vida privada com a vida profissional é de extrema importância para a vida dos indivíduos e para o seu desempenho profissional. Nesse sentido, procurou-se conhecer a realidade dos enfermeiros portugueses. Importou assim compreender qual o apoio das organizações de saúde, das chefias e dos colegas e qual a influência das carateríst...
This paper describes the robotic agent ESTraquinas which participated in the Ciber-Rato contest of the Festival Nacional de Robótica 2002. Following the Walls is the most used behaviour in this kind of contests. But, if a robot uses this strategy, the decisions of when to enter and when to leave this behaviour is not trivial. In this paper we present and discuss some solutio...
Optical coherence tomography (OCT) is becoming one of the most important imaging modalities in ophthalmology due to its non-invasiveness and by allowing the visualisation the human retina structure in detail. It was recently proposed that OCT data embeds functional information from the human retina. Specifically, it was proposed that blood–retinal barrier status information is present within OCT data from the h...
Glycerol is a byproduct of biodiesel production through transesterification of oils and fat. This article discusses the chemical transformation of glycerol in ethers, acetals and esters of high technological applications, especially in the fuel sector. Glycerol hydrogenolysis, dehydration to acrolein and oxidation are discussed as well, to show the potential use of glycerol for production of plastic monomers. F...
In this work we present the results of glycerol etherification with benzyl alcohol, catalyzed by different solid acids. The mono-benzyl-glycerol ether was the main product in the reactions catalyzed by β zeolite and Amberlyst-35 acid resin, whereas di-benzyl-ether was formed in higher yield with the use of p-toluene-sulfonic acid and K-10 montmorillonite as catalyst. Niobic acid was inactive in this reacti...
