In this work we explored PEGylation as an efficient strategy to improve esterases catalytic performance. For this, we PEGylated three esterases, namely lipase from Candida antarctica B (CALB), lipase from Thermomyces lanuginosus (TL) and cutinase from Fusarium solani pisi (CUT) and evaluated their catalytic performance by using the biosynthesis of poly(ethylene glutarate) as model reaction. After PEGylat...
This paper describes the development and implementation of an electronic platform for energy management in public buildings. The developed platform prototype is based on the installation of a network of wireless sensors using the emerging Long Range (LoRa) low power long-range wireless network technology. This network is used to collect sensor data, which is stored online and manipulated to extract knowl...
From the end of the 3rd millennium and the beginning of the 2nd millennium BCE, new motifs appear in Northwest Portugal. This corresponds to what one of the authors has called Figurative Art. The engravings of human feet—barefoot or with shoes—fall within this new “style”. This motif is not well known in Northern Portugal, although it has recently been the subject of a synthesis study on the Atlantic faç...
Conforme afirmam Deepak & Harneet (2010), os clientes estão mais atentos do que nunca. Segundo estes, o acesso à internet e às redes sociais, consideradas como agentes de inteligência, são fatores que afetam profundamente o comportamento dos consumidores. Através destes agentes, a identificação e localização do melhor preço ou do melhor produto/serviço é, hoje em dia, uma tarefa de espontânea concret...
During ageing, wood adsorbs volatile compounds from beverages. However, chemical interactions involved in sorption still remain unclear, as well as wood capacity to transfer such compounds to subsequent matrices when reused. Therefore, extractions were conducted from used wood manipulating variables such as ethanol concentration, contact temperature and pH, in order to determine their effect in the inter...
