Dual stimuli responsive poly(N-isopropylacrylamide) coated chitosan scaffolds f...

biomaterials for delivery of bioactive substances that can be controlled by external stimuli. Herein we report the production of smart partially biodegradable scaffolds that exhibit pH- and temperatureresponsive behavior and their effects on the release of a model protein and a drug of low molecular weight. Chitosan (CHT) scaffolds (pH sensitive) were coated/impregnated with a thermoresponsive polymer, poly(N-i...

O consumo sustentável como um vector de mitigação das alterações climáticas

Solar climate of Azores: results of monitoring at Faial and Terceira islands

The North Atlantic archipelago of Azores (Portugal) consists of nine islands, located about 1,500 km from mainland Europe. Currently the Azores has about 243,000 inhabitants, which depend heavily on imported fossil fuel for their energy supply. This is a concern for the regional Government and its Agency for Energy and Environment, ARENA, which naturally support energy efficiency and use of renewable energies. ...

Arquitetura do sistema radicular do porta-enxerto de videira 'IAC 766' na época...

Na propagação de porta-enxertos de videira por estaquia em recipientes para posterior transplante ao campo, é importante evitar danos ao sistema radicular. O objetivo do trabalho foi determinar, por meio da avaliação da arquitetura do sistema radicular, a melhor fase de desenvolvimento da muda para o transplante, ao campo, do porta-enxerto de videira 'IAC 766' Campinas, em Marialva - PR. As plantas foram avalia...

The development and application of a model for power output in a wind park

Uma abordagem espectral à geração de séries correlacionadas de vento

On the effect of the utility grid characteristics in a wind park power output f...

The influence of transmission system disturbances on the dynamic behaviour of a...

In this paper an integrated non-linear model of both the wind park and the interconnecction network is presented. The model is an integartion of model previously developed for each componenet of the system, namely wind turbines, induction generators, reactive power compensation system, transformers, feeder and possible local loads connected to the feeder. In order to draw some conclusions regarding the interact...
