Copyrolysis of sewage sludge–coal blends at different ratios (0:100, 10:90, 50:50 and 100:0) was investigated using a simultaneous thermogravimetry–mass spectrometry analyser. During copyrolysis three thermal decomposition stages were identified between 180 and 800°C. From 180°C to 385°C,...

In this study, we measure jointly the labour and the residential accessibility of a basic spatial unit using a Bayesian Poisson gravity model with spatial effects. The accessibility measures are broken down into two components: the attractiveness component, which is related to its socio-economic...

In recent decades there has been an increasing interest in the use of low voltage small grid-connected photovoltaic (PV) systems, conditioned by new incentives from distinct countries. An essential element in those systems is the inverter, that is, the element which converts, in an efficient...
