Blood flow visualization and measurements in microfluidic devices fabricated by...

The most common and used technique to produce microfluidic devices for biomedical applications is the soft-lithography. However, this is a high cost and time-consuming technique. Recently, manufacturers were able to produce milling tools smaller than 100 μm and consequently have promoted the ability of the micromilling machines to fabricate microfluidic devices capable of performing cell separation. In this wor...

Mitogenomic phylogeny and fossil-calibrated mutation rates for all F- And M-typ...

The Unionidae represent an excellent model taxon for unravelling the drivers of freshwater diversity, but, phylogeographic studies on Southeast Asian taxa are hampered by lack of a comprehensive phylogeny and mutation rates for this fauna. We present complete female- (F) and male-type (M) mitogenomes of four genera of the Southeast Asian clade Contradentini+Rectidentini. We calculate substitution rates for the ...

Associação longitudinal do rendimento na corrida da milha com parâmetros antrop...

A finalidade deste estudo foi a de analisar a modificação do rendimento na corrida da milha, a par de alterações no consumo máximo de oxigénio (VO2max), velocidade a que ocorre o VO2max (VelVo2max), velocidade a que ocorre uma concentração de lactato sanguíneo de 4 mmol/L (V4), índice de massa corporal (IMC), volume semanal e intensidade no treino intervalado, ao longo de uma época desportiva num corredor de me...

Trust and risk management towards resilient large-scale cyber-physical systems

Empowering distributed entities with decisional and adaptation capabilities is the current trend in control systems operating in highly changing environments. Cyber-Physical Systems (CPS) is a paradigm addressing this challenge as it allows the integration of both physical and decisional parts. By acting in highly changing environments, these complex control systems must be resilient. This paper proposes a trus...

Formação de Professores e Educadores: desafios éticos da ação e da investigação

A profissão docente, como é entendida atualmente, pressupõe um conjunto de saberes que estão relacionados: (i) com a ação envolvida nos processos complexos de promover ambientes de aprendizagem ricos e diversificados que potenciem o desenvolvimento das crianças, e, simultaneamente, (ii) com a construção de um saber profissional sustentado cientificamente. A formação inicial de professores e educadores de infânc...

Projecto estrela: expressão artística e TIC no ensino básico

Este documento pretende sistematizar de uma forma breve o trabalho que foi desenvolvido por um grupo de docentes e alunas da ESTGM na Escola Básica Nuno Canavez, de Mirandela, no 2º semestre do ano lectivo de 2005-2006, com a turma do 3º ano. Este trabalho caracterizou-se por uma preocupação em estabelecer uma prática educativa baseada num conjunto de áreas do saber relacionadas com as expressões artísticas, ma...

The concept of separation volume for the design of SMB processes

Optimization of the cyclic In-plane response of reinforced concrete frames with...

A typical option in building construction is the use of reinforced concrete frame structures with infill masonry walls . The presence of infill walls in frame structures greatly influences the dynamic behavior of frame structures during seismic events. This wall usually does not have a structural role, being neglected in the design phase of building structures. Innumerous negative effects may arise from the neg...

Incorporating fire-smartness into agricultural policies reduces suppression cos...

In southern Europe, land abandonment and an unbalanced investment toward fire suppression instead of pre-vention has gradually increased wildfire risk, which calls for a paradigm change in fire management policies. Here we combined scenario analysis, fire landscape modelling, and economic tools to identify which land-use policies would reduce the expected wildfire-related losses in the Transboundary Biosphere R...

Magnetic carbon xerogels for the catalytic wet peroxide oxidation of sulfametho...

Novel magnetic carbon xerogels consisting of interconnected carbon microspheres with iron and/or cobalt microparticles embedded in their structure were developed by a simple route. As inferred from the characterization data, materials with distinctive properties may be directly obtained upon inclusion of iron and/or cobalt precursors during the sol-gel polymerization of resorcinol and formaldehyde, followed by ...
