Microwaves, a form of electromagnetic radiation with high frequencies and short wavelengths, are often used for de-emulsification because various emulsion phases are susceptible to separation owing to the intense twisting of polar molecules and abrupt temperature increases caused by microwave vibration. This study was the first to prepare three-phase emulsions of biodiesel-in-nitromethane-in-diesel...
Most existing 3D image quality metrics use 2D image quality assessment (IQA) models to predict the 3D subjective quality. But in a free viewpoint television (FTV) system, the depth map errors often produce object shifting or ghost artifacts on the synthesized pictures due to the use of Depth Image Based Rendering (DIBR) technique. These artifacts are very different from the ordinary 2D distortions...
The xylanase gene from the rumen fungus Neocallimastix frontalis was expressed in Pichia pastoris and Pichia methanolica. Using a complex medium with medium replacement before induction and the maintenance of the methanol induction level at 0.5%, P. pastoris was able to produce about 5400U/ml of xylanase after 10 days of induction. With P. methanolica, on the other hand, about 6200U/ml of xylanase...
