Metodologia de Suporte à Utilização de Sistemas Interativos

Interactive systems users still face several challenge. Besides current improvements in usability and intuitiveness users have to adapt to the systems proposed to satisfy their needs. For instance, they must learn how to achieve tasks, how to interact with the system, etc. This paper proposes a methodology to improve this situation supporting the use of interactive systems by users. To achieve this goal the app...

Collagen type IV-related nephropathies in Portugal: pathogenic COL4A5 mutations...

Pathogenic mutations in genes COL4A3/COL4A4 are responsible for autosomal Alport syndrome (AS) and thin basement membrane nephropathy (TBMN). We used Sanger sequencing to analyze all exons and splice site regions of COL4A3/COL4A4, in 40 unrelated Portuguese probands with clinical suspicion of AS/TBMN. To assess genotype-phenotype correlations, we compared clinically relevant phenotypes/outcomes between homozygo...

Enhanced lipidic algae biomass production using gas transfer from a fermentativ...

In order to produce single-cell oil for biodiesel, a yeast and a microalga were, for the first time, grown in two separate reactors connected by their gas-phases, taking advantage of their complementary nutritional metabolisms, i.e., respiration and photosynthesis. The yeast Rhodosporidium toruloides was used for lipid production, originating a carbon dioxideenriched outlet gas stream which in turn was used to ...

Biomass quality in a thermoelectric plant along one year

ABSTRACT: The biomass quality is an important issue for the operation of a thermoelectric plant. Independently of the combustion technology, the biomass fuels and its characteristics are responsible for some operating problems during the thermochemical conversion of the biomass in thermal energy. These operation problems are related to the boiler and heat exchangers, dedusting technologies (e.g., electrostatic ...

A biorefinery from Nannochloropsis sp. microalga – Energy and CO2 emission and ...

Are microalgae a potential energy source for biofuel production? This paper presents the laboratory results from a Nannochloropsis sp. microalga biorefinery for the production of oil, high-value pigments, and biohydrogen (bioH2). The energy consumption and CO2 emissions involved in the whole process (microalgae cultivation, harvest, dewater, mill, extraction and leftover biomass fermentation) were evaluated. An...

Nuclear microscopy as a tool in TiO2 nanoparticles bioaccumulation studies in a...

Engineered Titanium nanoparticles are used for a wide range of applications from coatings, sunscreen cosmetic additives to solar cells or water treatment agents. Inevitably environmental exposure can be expected and data on the ecotoxicological evaluation of nanoparticles are still scarce.The potential effects of nanoparticles of titanium dioxide (TiO2) on two model organisms, the water flea, Daphnia magna and ...

Síndrome do bebé abanado – experiência de 10 anos de um Serviço de Cuidados Int...

Introdução: O Síndrome do Bebé Abanado é uma das causas de lesão não acidental mais difíceis de diagnosticar. Objetivos: Caracterizar os doentes internados no Serviço de Cuidados Intensivos Pediátricos (SCIP) com Síndrome do Bebé Abanado. Material e Métodos: Estudo retrospetivo dos doentes internados no SCIP do Centro Hospitalar de São João com o diagnóstico de Síndrome de Bebé Abanado de 1 de Janeiro de 1999 a...
