Pectic substances in the cell wall have long thought to
be responsible for the textural changes in fruit during
ripening and senescence. Compositional variation within
the pectic macromolecules could affect the external
characteristics of the fruit. Strawberries undergo adverse
quality changes such as softening and juice loss after
freezing and...
A decreasing rate of flow was observed (after sufficient air and particulate matter were removed from the wood and water) under steady-state conditions for green western hemlock sapwood. The decrease is theorized to be due to viscoelastic behavior of pit membranes. An unsteady-state procedure for determining longitudinal liquid permeability of...
Modulation assistance is widely employed to improve chip management in turning. This process is also known as modulated turning. Modulated turning transforms continuous cutting into intermittent cutting by periodically disengaging the tool tip from the workpiece, resulting in the generation of short, easily managed chips. This novel method improves the...
The characteristics of Northern squawfish
(Ptychocheilus oregonensis) and the feasibility of utilization
of this species for human consumption were investigated. In
the first experimental phase, the iced storage characteristics
of squawfish were determined. Quality changes were monitored
over 24 days of storage by chemical, physical, microbiological
and sensorial methods of...
A small eddy viscosity or mass diffusivity that varies with height has been found to have unexpected effects on the Kelvin-Helmholtz (KH) instability of a stably stratified shear layer near the neutral stability boundary. In particular, varying viscosity can increase the growth rate of the instability in contrast to the...
SH 714 (1, 2-alpha-methylene-6-chloro-delta-4, 6-17-alphahydroxyprogesterone
acetate) synthesized by Schering AG is an highly
antiandrogenic, nonestrogenic compound. The present investigation
was undertaken to determine the compound's effect upon the cell
associations of the germinal epithelium in the mature rat. From germinal epithelium for this dosage level of SH 714 was exhibited...
