Peer observation of teaching at U.Porto: a multidisciplinary approach to peer observation of teaching

The Peer Observation of Teaching at U. Porto ("De Par em Par na U.Porto") project is a peer observation of teaching (POT) program whose main goal was, since the beginning, to use peer observation for teachers' training purpose. It started as pilot program between the Faculty of Engineering and the Psychology and Education Science Faculty of the University of Porto, in 2009. Since 2010 it has been widespread to the most of the 14 Faculties and Schools of the University of Porto, involving over...

Gloeothece sp. as a Nutraceutical Source - An Improved Method of Extraction of Carotenoids and Fatty Acids

The nutraceutical potential of microalgae boomed with the exploitation of new species and sustainable extraction systems of bioactive compounds. Thus, a laboratory-made continuous pressurized solvent extraction system (CPSE) was built to optimize the extraction of antioxidant compounds, such as carotenoids and PUFA, from a scarcely studied prokaryotic microalga, Gloeothece sp. Following green chemical principles and using a GRAS solvent (ethanol), biomass amount, solvent flow-rate/pressure, t...
