CO2 Concentration in Day Care Centres is Related to Wheezing in Attending Children

Poor ventilation at day care centres (DCCs) was already reported, although its effects on attending children are not clear. This study aimed to evaluate the association between wheezing in children and indoor CO2 (a ventilation surrogate marker) in DCC and to identify behaviours and building characteristics potentially related to CO2. In phase I, 45 DCCs from Lisbon and Oporto (Portugal) were selected through a...

Alergia a Medicamentos Reportada em Crianças que Frequentam Infantários

Introdução: A prevalência de alergia a fármacos na população geral não se encontra devidamente caraterizada, existindo poucos estudos publicados que tenham abordado esta situação em crianças com idades inferior a seis anos de idade. Este estudo tem como objetivo principal estimar a prevalência de alergia a medicamentos reportada pelos pais de crianças de infantários de Lisboa e do Porto. Material e Métodos: No ...

PSCoP: A Planning Scheduler Coprocessor

The use of a centralised planning scheduler in fieldbus-based systems requiring real-time operation has proved to be a good compromise between operational flexibility and timeliness guarantees.In this paper a preliminary implementation of a hardware scheduling coprocessor based in the planning paradigm is presented. The coprocessor is installed in a special node of the fieldbus, the bus arbiter, and generates s...

Cianose no pequeno lactente – desafio diagnóstico

Osteoblast, fibroblast and in vivo biological response to poly(vinylidene fluorid...

Electroactivematerials can be taken to advantage for the development of sensors and actuators as well as for novel tissue engineering strategies. Composites based on poly(vinylidenefluoride),PVDF,have been evaluated with respect to their biological response. Cell viability and proliferation were performed in vitro both with Mesenchymal Stem Cells differentiated to osteoblasts and Human Fibroblast Foreskin 1. In ...

Displacement and strain field assessment of PDMS using digital image correlation

The main goal of this work is the characterization of the hyper-elastic mechanical behaviour of PDMS. The special specimens of PDMS (Sylgard® 184) were tested in a bi-axial tensile machine. The displacement and strain fields were measured using a commercial digital image correlation system (ARAMIS of GOM) during the tensile test. The experimental measurements are compared with numerical simulations, which use t...

Displacement and strain field assessment of PDMS using digital image correlation

The main goal of this work is to characterize the hyper-elastic mechanical behaviour of PDMS. For that, were made-up special specimens of PDMS (Sylgard® 184) for test them in bi-axial tensile machine. During the tensile test was used a commercial digital image correlation system (ARAMIS of GOM) to obtain de displacement and strain fields. These measurements are compared with numerical simulations which uses the...
