Exploring dynamic lighting, colour and form with smart textiles
This paper addresses an ongoing research, aiming at the development of smart
textiles that transform the incident light that passes through them – light transmittance – to
design dynamic light without acting upon the light source. A colour and shape change
prototype was developed with the objective of studying textile changes in time; to explore
temperature as a dynamic variable through electrical activation of the smart materials and
conductive threads integrated in the textile substrate; and to analyse the relation between textile
chromic and morphologic behaviour in interaction with light. Based on the experiments
conducted, results have highlighted some considerations of the dynamic parameters involved in
the behaviour of thermo-responsive textiles and demonstrated design possibilities to create
interactive lighting scenarios.This work is supported by FEDER funds through the Operational Programme for Competitiveness Factors – COMPETE and National Funds through FCT – Foundation for Science and Technology within the scope of the projects SFRH/BD/87196/2012, POCI-01-0145-FEDER-007136 and UID/CTM/00264.

Botulismo Infantil em Portugal – Um Lactente com Hipotonia
O Botulismo Infantil (BI) constitui uma síndrome neuroparalítica rara, potencialmente fatal, causada pela neurotoxina do Clostridium botulinum. Descreve-se o primeiro caso reportado
desde o início da notificação obrigatória em Portugal (1999). Lactente de dois meses, internado por prostração, dificuldade alimentar e obstipação. Constatou-se envolvimento inicial dos pares cranianos associado a fraqueza muscular progressiva, descendente e simétrica. Constituíam factores
de risco o consumo de mel caseiro e o banho com ervas de camomila. A confirmação diagnóstica foi efectuada pela pesquisa de esporos de Clostridium botulinum nas fezes e pela prova de inoculação em ratinhos. O tratamento implicou suporte respiratório e nutricional, e imunoglobulina humana
anti-toxina, com evolução favorável. A clínica e o contexto epidemiológico são importantes para o diagnóstico, permitindo
a instituição precoce do tratamento
Production of grape juice powder obtained by freeze-drying after concentration by reverse osmosis.
This study aimed to evaluate the freeze-drying process for obtaining grape juice powder by reverse osmosis using 50% grape juice pre-concentrated (28.5 °Brix) and 50% hydrocolloids (37.5% maltodextrin and 12.5% arabic gum)
