Transition phenomena commonly occur in nature. These arise
either due to structural or behavioral changes in the medium. Examples
for these abound in all applied sciences and to mention a few
of these, we have, boundary layer, elastic-plastic deformation, and
shocks. The present work is devoted to the study of...
Research was conducted to determine the distance and amount
of outcrossing between varieties of highly fluorescent annual ryegrass
(Lolium multiflorum Lam.) and low-fluorescing perennial
ryegrass (Lolium perenne L.). Studies were conducted under both
spaced-plant and seed production field conditions.
Fluorescence tests on seed collected from low-fluorescing
perennial ryegrass at successive...
Food lipid systems are very complex and so is oxidative
degradation that render them unpalatable for human consumption.
The significance of lipid degradation and the key reactions involved
have been thoroughly studied and are well understood today. This
is not true, however, of the secondary products of the autoxidation
reactions....
4-Pyridoxic acid is the major metabolite of all forms of
vitamin B₆ in mammalian species. The determination of 4-pyridoxic
acid, therefore, is important in the investigation of vitamin B₆
metabolism and for the establishment of human requirements for the
vitamin.
Although 4-pyridoxic acid is itself fluorescent, Huff and
Perlzweig (1944)...
The author shows that a necessary and sufficient condition
for a convex polyhedron to be representable as a finite vector sum
of line segments is that each of its faces possesses central symmetry.

Malonaldehyde, a very reactive member of the homologous
series of dialdehydes, is associated with the autoxidative deterioration
of lipids. Its measurement, in autoxidized lipid systems is an
expression of the extent of oxidation, in lipids. Malonaldehyde lends
itself well to such determinations because of the sensitivity and
specificity of its...
An experimental study has been made of the local natural convective
heat transfer coefficient around the circumference of a heated
horizontal cylinder oscillating vertically in water. The heat transfer
surface consisted of a 1 3/8-inch diameter cylinder with a small test
section imbedded in its surface. This enabled data to...
