The convex sets strict separation is very useful to obtain mathematical optimization results. The minimax theorem, a key result in Game Theory is an example. It will be outlined in this work.
Transglutaminases are a family of enzymes (EC 2.3.2.13), widely distributed in various organs, tissues, and body fluids, that catalyze the formation of a covalent bond between a free amine group and the γ-carboxamide group of protein or peptide-bound glutamine. Besides forming these bonds, that exhibit high resistance to proteolytic degradation, transglutaminases also form extensively cross-linked, generally in...
In this work the dispersion characteristics of random spans in a installed private fiber-optic network are discussed, and some field testing measurements techniques are evaluated. ; Neste trabalho discute-se a caracterização da dispersão numa rede óptica em operação e avalia-se a técnica de campo mais usada na medição da dispersão (desvio de...
RESUMO Introdução: A má evolução ponderal encontra-se entre um dos motivos mais frequentes de referenciação à consulta de Pediatria. As dificuldades encontradas na definição desta entidade e as diferentes abordagens desta situação tornam difícil uma homogeneização de critérios e atitudes. Objetivo: Orientar a abordagem e seguimento das crianças com má evolução ponderal. Métodos: Revisão de artigos pertinentes p...

Nowadays a great interest is devoted to the production and use of biobased products. The main scope of the oxypropylation process is to obtain polyols, in the form of viscous liquids, which can be interesting co-monomers to produce polyurethanes and polyesters. Due to the high hydroxyl content of natural polymers (suitable substrates to be oxypropylated), the generated polyols are multifunctional, hence most ad...
Civil Protection Local Means are a very important issue for Municipality Civil Protection Emergency Plans. So, it is crucial to have a detailed Geodatabase of the Civil Protection Local Means in order to produce a better and quick response in case of natural or technological hazard. In this work, we discuss the importance and the utility of a dynamic Geodatabase of Civil Protection Local Means, presenting the c...
Background Circulating endothelial cells (CEC) may be a biomarker of vascular injury and pro-thrombotic tendency, while circulating endothelial progenitor cells (CEP) may be an indicator for angiogenesis and vascular remodelling. However, there is not a universally accepted standardized protocol to identify and quantify these cells and its clinical relevancy remains to be established. Objectives To quantify ...
A composição do leite de cabra, assim como a quantidade produzida é influenciada por diversos factores entre eles a raça, a fase da lactação, alimentação e selecção dos animais, variando entre limites bastantes extensos em função dos factores em causa. As metodologias clássicas de programas de selecção de espécies produtoras de leite, são estabelecidas com base essencialmente nos registos da quantidade de leite...
