Poly(vinyl alcohol) with sulfonic acid groups as catalyst for the alpha-pinene alkoxylation

The alkoxylation of a-pinene was carried out over poly(vinyl alcohol) containing sulfonic acid groups, as catalyst. The main product of a-pinene alkoxylation was a-terpinyl methyl ether being also formed bornyl methyl ether, fenchyl methyl ether, limonene and terpinolene as by-products. The absorption band at 1037 cm-1 in the FTIR spectrum of PVA_SSA40 (PVA membrane containing 40% of –OH groups esterified with SSA) which does not appear in the spectrum of PVA, indicates the presence of the sulfonic acid groups. The catalytic activity of PVA with sulfonic acid groups increases when the amount of sulfosuccinic acid used in the polymer crosslinking is increased from 5% to 40%. However, when the crosslinking degree increases from 20% to 40%, the conversion of a-pinene increases only slightly. Good values of selectivity to a-terpinyl methyl ether were obtained over poly(vinyl alcohol) with sulfonic acid groups. A simple kinetic model, which fits experimental concentration data quite well, was developed.

Turismo, turistas e eventos: o caso da Ilha da Madeira

A presente investigação, conducente à obtenção do grau de Doutor em Turismo na Universidade de Évora, aborda a temática dos eventos culturais no âmbito da actividade turística na Ilha da Madeira. Nesse sentido, e definido o objecto, o objectivo geral da pesquisa consistiu em analisar o contributo dos principais eventos turísticos - Festa da Flor, Festa do Vinho e Festa do Fim-de-Ano - na valorização das tradições culturais da Ilha e na promoção do destino Madeira. Para atingir os objectivos definidos, foi utilizada uma metodologia dual que consistiu num abordagem quantitativa e qualitativa, através da administração de um inquérito por questionário, um inquérito por entrevista e da utilização da observação directa e/ou participante, em triangulação que considerou o lado da procura e o lado da oferta. Foi possível concluir que os eventos analisados dão um contributo importante para a valorização das tradições, para a pertença e coesão social, e que enfatizam a interacção social entre turistas e anfitriões, ao mesmo tempo que consistem numa oferta singular e única; ABSTRACT: This dissertation was conceived to obtain the doctor degree in Tourism at the University of Évora. It approaches the theme of cultural events in the frame work of tourism activity in the island of Madeira. The main objective of the study was to analyze the contribution of the major tourist events (Flower Festival, Wine Festival and the Feast of the End-of-Year) on the value of cultural traditions of the island and the promotion of Madeira. The defined objectives were accomplished by the use of a dual methodology, through an approach of quantitative and qualitative orientation – by means of questionnaire to the tourists, interviews to the organisers and direct and participant observation by the researcher. We can conclude about the cultural importance of the three selected feasts (Flower Festival, Wine Festival and the Feast of the End-of-Year) as a major contribute to value the tradition, to emphasize the social cohesion, to identify the tourist experience and to evaluate social interaction between hosts and guests as an unique and singular offer.

Logic Programming and Artificial Neural Networks in Pharmacological Screening of Schinus Essential Oils

Some plants of genus Schinus have been used in the folk medicine as topical antiseptic, digestive, purgative, diuretic, analgesic or antidepressant, and also for respiratory and urinary infections. Chemical composition of essential oils of S. molle and S. terebinthifolius had been evaluated and presented high variability according with the part of the plant studied and with the geographic and climatic regions. The pharmacological properties, namely antimicrobial, anti-tumoural and anti-inflammatory activities are conditioned by chemical composition of essential oils. Taking into account the difficulty to infer the pharmacological properties of Schinus essential oils without hard experimental approach, this work will focus on the development of a decision support system, in terms of its knowledge representation and reasoning procedures, under a formal framework based on Logic Programming, complemented with an approach to computing centered on Artificial Neural Networks and the respective Degree-of-Confidence that one has on such an occurrence.

Clínica de ruminantes

O presente relatório surge na sequência da realização do estágio curricular na coo-perativa Fomento Extremeño Ovino Sociedad Agraria de Transformación no âmbito do Mestrado Integrado em Medicina Veterinária na Universidade de Évora. Este relatório apresenta-se dividido em duas partes. Na primeira são descritas as atividades desenvolvi-das no controlo reprodutivo, profilaxia médica e clínica médica. A segunda parte é cons-tituída por uma revisão bibliográfica sobre o tétano em ovinos, patologia que tem especial importância nesta espécie devido aos procedimentos realizados no maneio ainda muito tradicionais, e no final são apresentados dois casos clínicos e a sua respetiva discussão à luz do estado de arte; Ruminants clinics Abstract: This report follows up on the completion of the internship at the Fomento Extre-meño Ovino Sociedad Agraria de Transformación as part of the Master Degree in Vete-rinary Medicine at the University of Évora. Thereby the present repor is divided into two parts. The first part describes the activities performed in reproductive control, medical prophylaxis and medical clinic. The second part is composed by a bibliographical review about tetanus in sheeps, a pathology that has special importance in this species due to animal management procedures performed wich are still very tradicional. Lastly, this re-port presents two clínical cases and its respective discussion according to presente knowledge.

Patologia e clínica de equinos

O presente relatório de conclusão do curso de Mestrado Integrado em Medicina Veterinária da Universidade de Évora, refere-se ao período de estágio curricular obrigatório que decorreu na Clínica Equifort, em Fortaleza, Brasil, na área Patologia e Clínica de Equinos. Numa primeira fase é feita uma descrição das atividades desenvolvidas onde se apresenta a casuística acompanhada durante o estágio, que inclui atividades em diversas áreas como medicina desportiva, clínica médica, clínica reprodutiva, clínica cirúrgica e clínica hospitalar.
