A computational investigation using a unique model and a solution algorithm was conducted, changing only the saturation pressure of one material artificially during nanopowder formation in thermal plasma fabrication, to highlight the effects of the saturation pressure difference between a metal and silicon. The model can not only express any profile of particle size-composition distribution for...

Particle transport in magnetized plasmas is investigated with a fluid model of drift wave turbulence. An analytical calculation shows that magnetic field curvature and thermodiffusion drive an anomalous pinch. The curvature driven pinch velocity is consistent with the prediction of turbulence equipartition theory. The thermodiffusion flux is found to be directed inward for a small ratio of elec...

A numerical model was used to examine experimental data in which a gas chromatograph measured the composition of gas sampled through a 70-pn orifice in the growth substrate during atmospheric-pressure RF plasma diamond CVD. Substantial discrepancies were found between the measurements and the predicted species mole fractions at the surface, but the data were in much better accord with predicted...

Non-thermal plasma is increasingly being recognized for a wide range of medical and biological applications. However, the effect of non-thermal plasma on physiological functions is not well characterized in in vivo model systems. Here we use a genetically amenable, widely used model system, Drosophila melanogaster, to develop an in vivo system, and investigate the role of non-thermal plasma in ...

Since the 1980s applications of thermal plasmas experienced an important increase. In the 1990s fundamental research led to great progress in the understanding of the basic phenomena involved, and to a renewed interest in applying thermal plasmas to material processing and waste treatment. The application of plasma torches for environmental purposes is a relatively new process. Thermal plasma o...

Plasma cortisol concentration as estimated by CPB radioassay increased significantly in cattle during 4 hr of acute thermal exposure while plasma progestins did not. Changes in plasma cortisol were gradual with the onset of heat exposure and correlated significantly with rectal and environmental temperatures although the correlation was greater with rectal temperature. However, the rise and dec...

High impact polystyrene (HIPS)/corn starch blends were prepared in presence of glycerol as a plasticizer via melt extrusion process by a twin-screw extruder. The novelty of this work is first, because of the use of pre-gelatinized corn starch as modified one and second, the procedure of making blends by extruder which makes it ease of access and also industrially possible. The blends were then ...
