Using a novel method that couples genetic algorithm (GA) with numerical simulation, the geometric configuration for a two-dimensional slotted fin has been optimized in this paper. The objective of optimization is to maximize the heat transfer capacity of slotted fin, and minimize the pressure...

During anaerobic fermentation of waste activated sludge (WAS), the production of short-chain fatty acids (SCFAs), especially propionic acid which is considered as the most preferred carbon source for enhanced biological phosphorus removal, can be improved by controlling the suitable mass ratio...

Biodiesel, an ideal alternative to fossil fuels, is very imperative for the sustainable development of mankind. Among its preparation technologies, biotechnological preparation is the most promising one. This study critically reviews the current progresses in biocatalysts (lipases),...
