Disponibilização de cursos à distância : uma reflexão

O ensino/aprendizagem à distância pode ser uma forma de ultrapassar alguns dos problemas causados pelo crescente número de candidatos a maiores níveis de qualificação, num contexto em que os recursos não evoluem na mesma proporção. Existem variadas abordagens ao problema da disponibilização de sistemas de suporte ao ensino/aprendizagem à distância, bem como dos cursos que nesse contexto podem ser oferecidos. A...

Site-condition map for Portugal based on Vs30 values and evaluation of the appl...

Maps providing information on site conditions are essential tools to accurately represent the spatial distribution of ground motions, both in seismic hazard maps and in instrumental intensity maps (ShakeMaps). Project SCENE, funded by the Portuguese Foundation for Science and Technology, aims at characterizing the site conditions for Portugal and to outline a first-order site effects map to be used in seismic h...

Leveraging knowledge from different communities using ontologies

The purpose of this paper is to provide research based understanding of leveraging knowledge and managing knowledge within and across several communities using the poverty domain as a case study. We hypothesize that leveraging knowledge with a good taxonomy and a good integration process are good approaches to organize and share knowledge. Problems appear when a group of people in different communities share da...

Semantic interrelation in distributed system through green computing ontology

Green computing refers to the system that provides minimal impact on the environment. When we are talking about green computing we discuss about how much energy is used by the system, such as energy used by the system, time used for the search process, and how effective the system is. Related to that issue, trough this paper we want to proposes a new effort to achieve Green Computing in heterogeneous data in di...

Solving problem of ambiguity terms using ontology

Humans as God's creatures were endowed with brain used to think and to process the received knowledge. Human brain links knowledge into a giant network of ideas, memories, predictions and beliefs. Everything is interconnected in the brain. Human can understand the meaning of the same variable even if that variable has an ambiguous meaning. In another scenario, humans can understand the same thing based on diffe...

Blood-brain-barriers in aging and in Alzheimer's disease

The aging process correlates with a progressive failure in the normal cellular and organ functioning; these alterations are aggravated in Alzheimer's disease (AD). In both aging and AD there is a general decrease in the capacity of the body to eliminate toxic compounds and, simultaneously, to supply the brain with relevant growth and nutritional factors. The barriers of the brain are targets of this age related...

Mestrado em Viticultura e Enologia - Instituto Superior de Agronomia / Faculdade de Ciências. Universidade do Porto ; This study was created with a purpose of searching for an effective method of promoting an higher concentration of colour compounds in the wine, on Merlot variety. We evaluated the effects of three different canopy management practices in the vineyard: early defoliation at pre-bloom (DF), parti...

Hoje em dia na literatura está disponível uma grande quantidade de informação sobre os aspetos químicos e biológicos dos produtos apícolas, no entanto a informação científica fundamentada sobre a sua utilização terapêutica é limitada. O objetivo deste estudo foi avaliar o perfil fenólico, a atividade antimicrobiana in vitro e o efeito sobre a enzima hialuronidase (amplamente relacionado com o processo de inflam...
