The objective was to carry out a systematic review of randomized trials on the magnitude of post exercise hypotension (PEH) in adults. 1336 studies were retrieved from PubMed, Scielo and Lilacs, after searching "exercise" and "hypotension". 1268 papers were excluded by titles, 37 by abstracts, 10 were nonrandomized, 1 by repeating data, leaving 20. These studies were evaluated according to the randomization, bl...
Tese de mestrado em Matemática, apresentada à Universidade de Lisboa, através da Faculdade de Ciências, 2013 ; O estudo das classes de grupos finitos teve a sua origem com o trabalho de Gaschütz. No entanto, o tema central desta tese serão os conceitos desenvolvidos por Fischer , numa tentativa de dualizar a teoria construída por Gaschütz. Com estas ferramentas, provaremos um teorema importante de Fischer et a...
The development of intelligent environments requires handling of data perceived from users, received from environments and gathered from objects. Such data is often used to implement machine learning tasks in order to predict actions or to anticipate needs and wills, as well as to provide additional context in applications. Thus, it is often needed to perform operations upon collected data, such as pre-processi...
Intelligent environments and ambient intelligence enabled systems provide means to gather rich information from both environments and its users. With the help of such systems, it is possible to foster communities of ambient intelligence systems with community driven knowledge, which is created by individual actions and setups in each of the environments. Such arrangements provides the potential to build systems...
No contexto da energia é de notar que Portugal tem poucos recursos fósseis daí o crescente interesse da comunidade científica em soluções energéticas mais amigas do ambiente, as energias renováveis, das quais eu sou adepto, e acredito que venham a vincar futuramente na produção de energia necessária à vida humana. Dada a minha ideologia inscrevi-me no decurso da minha vida académica no Mestrado em Controlo e El...

The aim of this study was to evaluate the in vitro antioxidant effects of 12-[(2R,5R,6R)-5-hydroxy-6-methylpiperidin-2-yl]dodecan-2-one (iso-6-cassine; ISO) and the anticonvulsant effects of ISO on pilocarpine-induced seizures in rats. Wistar rats were treated with 0.9% saline (i.p., control group), pilocarpine (400 mg/kg, i.p., pilocarpine group), and the association of ISO (1.0 mg/kg, i.p.) plus pilocarpine (...
The São Francisco Submedium Valley is located at the Brazilian semiarid region and is an important center for irrigated fruit growing. This region is responsible for 97% of the national exportation of table grapes, including seedless grapes. Based on the fact that organic fertilization can improve soil quality, we compared the effects of conventional and organic soil management on microbial activity and mycorrh...
É na Grécia, no século VII a.C., que surge uma mulher-escritora pioneira, Safo (a “mãe” da poesia feminina), inscrevendo o seu discurso poético-amoroso dirigido a outras mulheres. Passados muitos séculos, é só no começo do século XX que surgirá em Portugal outra escritora, Judith Teixeira, que tentará ultrapassar o conservadorismo nacional, cultivando uma linguagem “sáfica” e rompendo assim os paradigmas impost...
