The effects of laser processing of Ni₃Al, TiAl,
Fe₃Al, and Ni₃Si on microstructure and phase
composition were characterized using optical and
scanning electron microscopy and X-ray diffraction
analysis. It was found that laser processing
resulted in melt zones of ordered phases with fine
grains and microstructures. The effects of heat...
Gastric retention time of single unit dosage forms in swine was found
to be much longer than in humans. It was concluded that swine are not a
good animal model to study GI transit time of nonerodable or slowly eroded
dosage forms. Noneradable and slowly eroded dosage forms used to...
A mathematical model was developed using
finite difference numerical techniques to examine the
effects of kinetic parameters on the fate of
hydrophobic organic compounds in soil systems. The
model included advection; dispersion; bacterial
metabolism; and sorption and desorption to soil solids
and bacteria, and degradation by bacteria. The most
important...
