Question??rio de Percep????es Acad??micas-Expectativas : contributos para a sua...

Volume tem??tico da Revista e-psi "Adapta????o e sucesso acad??mico no ensino superior" ; O estudo das expectativas acad??micas de estudantes do primeiro ano tem mostrado a sua import??ncia na qualidade da adapta????o, persist??ncia e sucesso acad??mico no Ensino Superior. O Question??rio de Percep????es Acad??micas - Expectativas (QPA-E; Almeida, Dea??o, et al.,2012) constitui um instrumento de avalia????o de...

Investigating Population Structure of Sea Lamprey (Petromyzon marinus, L.) in W...

This study hypothesizes the existence of three groups of sea lamprey Petromyzon marinus L. in Portugal (North/Central group, Tagus group, and Guadiana group), possibly promoted by seabed topography isolation during the oceanic phase of the life cycle. Within this context, our purpose was to analyze the existence of a stock structure on sea lamprey populations sampled in the major Portuguese river basins using b...

Benefits of spine stabilization with biodegradable scaffolds in spinal cord inj...

Spine stabilization upon spinal cord injury (SCI) is a standard procedure in clinical practice, but rarely employed in experimental models. Moreover, the application of biodegradable biomaterials for this would come as an advantage as it would eliminate the presence of a nondegradable prosthesis within the vertebral bone. Therefore, in the present work, we propose the use of a new biodegradable device specifica...

Probing the surface chemistry of different oxidized MWCNT for the improved elec...

"This work reports the evaluation of a set of multi-walled carbon nanotubes (MWCNT) presenting different surface chemistries, as interfaces for the direct electrochemistry of the multihemic nitrite reductase (ccNiR) from Desulfovibrio desulfuricans ATCC27774 (Dd). The carbon nanotubes dispersions were prepared in aqueous media and deposited on pyrolytic graphite (PG) macroelectrodes, following a layer-by-layer ...

Sistemas de Transmissão/Recepção sem Fios por Raios Infravermelhos

This paper describes the results obtained in the characterisation, optimisation and test, of two wirelessinfrared communication systems. Although both systems arebased on the same technology they are used on differentapplications.On the first part of this paper an wireless optical indoorcommunication system, that uses angle diversity techniqueson the reception is presented. This optical receiver wasdevelop...

Clinical efficacy of biosimilar filgrastim in Fernando Fonseca Hospital, Portugal

Development and Characterization of a Novel Hybrid Tissue Engineering–Based Sca...

Spinal cord injury (SCI) represents a significant health and social problem, and therefore it is vital to develop novel strategies that can specifically target it. In this context, the objective of the present work was to develop a new range of three-dimensional (3D) tubular structures aimed at inducing the regeneration within SCI sites. Up to six different 3D tubular structures were initially developed by rapi...

Estudo da soldabilidade de aços de baixa liga C-Mo e Cr-Mo através do ensaio im...

Dissertação apresentada para obtenção do grau de Mestre em Materiais e Processos de Fabrico, na Faculdade de Engenharia da Universidade do Porto, sob a orientação do Prof. Doutor A. A. Fernandes

Antibacterial and antioxidant activities and acute toxicity of Bumelia sartorum...

In order to validate the Bumelia sartorum Mart., Sapotaceae, traditional use for infection diseases, this study evaluates the antibacterial activity of the stem bark fractions against methicillin-sensitive (MSSA) and methicillin-resistant (MRSA) Staphylococcus aureus strains by using the agar dilution method and reported as MIC (minimal inhibitory concentration). In addition, the DPPH scavenging activity of the...

Rotavirus infection in a tertiary hospital: laboratory diagnosis and impact of ...

BACKGROUND AND OBJECTIVES: Rotavirus (RV) is the main etiological agent of diarrhea in childhood; its laboratory diagnosis is crucial to guide the clinical management and prevention of its spread. RV immunization was introduced in Brazilian 6-month-old children in 2006. The present study was aimed to evaluate three methodologies used for human RV detection in stool samples obtained from patients hospitalized du...
