Background: This work studied how the exposure to an unusual substrate forced a change in microbial populations during anaerobic fermentation of crude glycerol, by-product biodiesel production, with freshwater sediment used as inoculum. Results: The associations almost completely (99.9%) utilized glycerol contained 6 g L-1 within four days, releasing gases, organic acids (acetic, butyric) and a...

In this paper, the short-term creep behavior of the Inconel-713C superalloy after different pre-treatments including the ageing and forging processes has been studied at 850 °C. The ageing heat treatment was heating at 930 °C for 16 hours without solutioning process. The optical microscopy (OM) and the scanning electron microscopy (SEM) techniques were applied for microstructural evaluations. T...

In this paper, a decentralized integrated control structure ...
