A construção da profissionalidade de um professor generalista e o desenvolvimen...

Serve o presente relatório para explicitar o processo de formação profissionalizante realizado ao longo de dois períodos de estágio, Educação Pré-Escolar e de 1ºCiclo do Ensino Básico, sendo que se encontram evidenciadas as especificidades, transversalidade e continuidade existentes em ambos os contextos. Para o efeito, realizou-se um estudo de natureza qualitativa, que resultou numa intervenção educativa pauta...

Prevalência de consumo de suplementos alimentares nos profissionais do Institut...

Atualmente, o estilo de vida da sociedade, nem sempre permite a ingestão de refeições equilibradas, o que despoleta os indivíduos a recorrer a suplementos alimentares para compensar a deficiente ingestão de certas substâncias, assim como prevenir diversas patologias.(1) Os suplementos alimentares são definidos como géneros alimentícios que se destinam a complementar e ou suplementar o regime alimentar normal e ...

Food contact surfaces coated with nitrogen-doped titanium dioxide : effect on L...

Improvement of food safety is a very important issue, and is on the basis of production and application of new/modified food contact surfaces. Titanium dioxide (TiO2) and, more recently, nitrogen-doped titanium dioxide (N-TiO2) coatings are among the possible forms to enhance food contact surfaces performance in terms of higher hygiene and easier sanitation. In this context, the present work aimed at evaluating...

Control of bacterial cells growths by magnetic hyperthermia

In this work, we report the effectiveness of magnetic hyperthermia as a potential disinfection method against food spoilage microorganisms. High structural-magnetic quality magnetite nanoparticles have been found to be effective against bacterial microorganisms in solution under an oscillating magnetic field. Samples containing both magnetite nanoparticles and Pseudomonas fluorescens cells in aqueous solution h...

Effect of magnetic hyperthermia on the structure of biofilm and cellular viabil...

This work evaluated the effect of magnetic hyperthermia (MH) on planktonic cells and biofilms of a major food spoilage bacterium Pseudomonas fluorescens and its performance compared to a conventional direct heating (DH) technique. The results showed that MH had a greater and faster bactericidal effect, promoting a significant reduction in cell viability (≥3 Log CFU) in planktonic and biofilm cells, and leading ...

Effect of magnetic hyperthermia on Pseudomonas fluorescens planktonic cells and...

Infective endocarditis in intravenous drug abusers : an update

Infective endocarditis despite advances in diagnosis remains a common cause of hospitalization, with high morbidity and mortality rates. Through literature review it is possible to conclude that polymicrobial endocarditis occurs mainly in intravenous drug abusers with predominance in the right side of the heart, often with tricuspid valve involvement. This fact can be associated with the type of drug used by th...

Control of planktonic bacterial cells and biofilms through magnetic hyperthermia

Disinfection of surfaces is a challenging task aggravated by bacteria's capacity to form biofilms, which enables them to survive and resist a wide variety of antimicrobial agents and hostile conditions. Potential application of magnetic hyperthermia (MH) as a new disinfection method against biofilms has been recently proposed however, studies comparing its performance and effectiveness on planktonic and biofilm...

Superhydrophobic poly(L-lactic acid) surface as potential bacterial colonizatio...

Hydrophobicity is a very important surface property and there is a growing interest in the production and characterization of superhydrophobic surfaces. Accordingly, it was recently shown how to obtain a superhydrophobic surface using a simple and cost-effective method on a polymer named poly(L-lactic acid) (PLLA). To evaluate the ability of such material as a substrate for bacterial colonization, this work ass...

Estudo de públicos do Museu Municipal de Penafiel

O interesse principal deste projeto foi a realização de um estudo de públicos que reúna uma sistematização de informações relativo ao público fruidor. Com as informações recolhidas pretendeu-se obter uma visão ampla dos públicos que usufruem daquele equipamento cultural. Neste sentido todo este documento resultou de uma investigação realizada no Museu Municipal de Penafiel, em Penafiel no ano letivo de 2011/201...
