The purpose of this study was to determine the phenolic
constituents of Bartlett pears and to evaluate the processed
samples for extent of discoloration and to relate the two.
Pears were obtained from three orchards in the Medford area
and from three orchards at each of the three elevations, 500,...
Rat liver microsomes are shown to contain an enzyme system
which converts the cyclodiene insecticides, aldrin, heptachlor and
isodrin to their corresponding epoxides, dieldrin, heptachlor epoxide,
and endrin. The microsomal fraction of 450 milligrams of liver from
male rats epoxidates 80 percent of a 20 to 50 microgram aldrin substrate...
This paper is a theoretical approach to solve
problems of horizontally curved beams Castiglione's
theorem is applied to solve for the fixed end bending
moments, maximum span moments and fixed end torsional
moments. To calculate the vertical deflection at the midspan
of the curved beam the moment-area method is used....
The paper concerns itself with the problem of heat transport
in a homogeneous, incompressible, isotropic, semi-infinite solid
whose boundary is nonstationary. The methods of solution in the one
dimensional case are discussed. Numerical examples and a method
for arriving at the solutions published by Bailey and Lakin in their
paper...
The abundance of copper was determined in four to six one-gram
specimens separated by a distance of several inches from each
of 23 large chondritic fragments (greater than 1 kg) via instrumental
neutron activation analysis and counting of the annihilation N-rays of
⁶⁴Cu. It is believed that an accuracy of...
The lipid composition of swine is characteristic of the species
and is also a reflection of their dietary history. Other investigators
have established that the physical properties and composition of
swine depot fat may be altered by variation of the dietary lipid.
Dietary regimens employing vegetable oil-bearing materials and
their...
This investigation is concerned with the determination of the temperature-effective period (T.E.P.) for crossvein development at physiological temperatures using three isogenic crossveinlesslike (cvl) lines of Drosophila melanogaster.
The method used to determine T.E.P. relies on temperature differences in phenotypes and on a program of transfers from one temperature to another...
In the present study, processed soymilks prepared by various
manufacturing methods were examined for quality by physical and
chemical methods. Viscosity, pH, soluble solids, total solids, fat
and protein content were used as indicators of quality. The principal
factor investigated was the protein content as measured by the
dye-binding procedure....
In the present study, the textural changes induced in Chinese
waterchestnuts by physical and chemical means were of prime concern.
After being subjected to chemical and heat treatments, the
corms were analyzed to relate the chemical changes with the physical
changes in the corms.
Chinese waterchestnuts were peeled, filled in...
