Tese de mestrado. Biologia (Biologia da Conservação). Universidade de Lisboa, Faculdade de Ciências, 2013 ; O Nemátode da Madeira do Pinheiro (NMP) representa a maior ameaça para as florestas de pinheiro em Portugal e na Europa. O NMP tem devastado extensas áreas de Pinus pinaster com consequências socioeconómicas significativas para o país. Por estas razões é fulcral atuar na gestão deste ecossistema, para ev...
Contrary to what usually occurs with other crops, grapevine varieties are mostly landraces that were domesticated by humans centuries or millennia ago from populations of wild grapevines (Vitis vinifera ssp. sylvestris). It is logical to assume that domestication was not been a single, instantaneous act by any of the first farmers but was rather a long succession of negative mass selections of wild plants, foll...
Objetivo: Contribuir para a clarificação do conceito de vigilância parental Método: Clarificação de conceito. Pesquisa nas bases de dados CINAHL e MEDLINE (palavras-chave parent, vigilance, child e hospitalized). Análise: No cuidado humano, a vigilância pode ser vista como, a capacidade de reação a uma situação crítica. (Benner e Whrubel, 1989) A vigilância familiar, teoria desenvolvida por Carr e Clark (1997),...
O presente relatório descreve um estudo de caso centrado na explicitação de algumas das propriedades centrais dos marcadores discursivos (MDs) em português europeu, com especial incidência nos marcadores contra-argumentativos, e na relevância do seu ensino-aprendizagem para o desenvolvimento da competência comunicativa de um grupo de estudantes de português como língua estrangeira, a frequentar o nível C, no 2º...
Tese de doutoramento, Química (Química Física), Universidade de Lisboa, Faculdade de Ciências, 2011 ; The work presented in this thesis was carried out at the Molecular Energetics group from “Centro de Química e Bioquímica” of “Faculdade de Ciências da Universidade de Lisboa”. The general research goal of the group is the study of the relationship between the energetics of molecules or groups of molecules and ...
Studies were undertaken on colour CIE L*a*b* values, vitamin C (ascorbic acid) and drip loss alterations of frozen broccoli (Brassica oleracea L. ssp. Italica) stored at isothermal ( 7, 15, and 25 C) and non-isothermal (accelerated life testing with step-stress methodology; temperature range from 30 to 5 C) conditions. The storage temperatures were selected according to conditions that occur in the cold c...
Proceedings of the International Conference “Environmentally friendly and safe technologies for quality of fruit and vegetables”, held in Universidade do Algarve, Faro, Portugal, on January 14-16, 2009. This Conference was a join activity with COST Action 924. ; Quality and safety attributes, like colour (CIELab parameters), texture (Maximum force – MF), total phenolics content (TPC), peroxidase activity (POD)...
From the massal and clonal selection of grapevine developed in Portugal for the last 30 years, clones of several varieties with high genetic potential were obtained, which are currently used for multiplication to produce base and certified materials. In order to allow the rapid multiplication of selected clones of grapevine, this work evaluate the effect of the variety (Arinto, Malvasia Fina, Aragonez, and Trin...
An experimental population containing 149 genotypes of the ‘Bravo’ apple randomly sampled all over it growing regions, as submitted to mass genotypic selection through the methods previously developed or other species such as grapevine. This study led to determining the coefficient of genotypic variation of some characteristics, as a quantifier of intra-varietal genetic diversity. The global values reveal the e...
