This histochemical study deals with the changing patterns of
glycogen in the uterus of the immature virgin, cycling virgin, and
post partum (non-lactating) golden hamster (Mesocricetus auratus
Waterhouse). The periodic acid-Schiff technique was...

This paper defines and discusses some of the separation
axioms of topological spaces. In the cases considered,
a search is made for sets of conditions which
would be equivalent in a space satisfying a given separation
axiom to the existence of a...

Two lots of six White Leghorn male chickens were fed diets containing
7.3% linoleic acid and either .075% ethoxyquin (lot 1) or 32.4
mg/kg of added vitamin E (lot II) for 47 weeks both of which were
designated as positive controls. A third group...

The purpose of this paper was to study the relationship of a
high school family life course to post high school problems and
marriage role expectations. The specific objective of the study was
to determine whether or not there is a relationship...

Three Oregon soil types (Chehalis silt loam (CSL), an alluvial
soil from the Willamette Valley; Ayre sandy loam (ASL), a volcanic
pumice soil from the Central high desert; and Klamath fine sandy
loam (KFSL), a basaltic mineral soil from the...

The western Plethodon include vandykei vandykei, v. idahoensis,
larselli, dunni,vehiculum, stormi, elongatus, and an undescribed
form referred to as the "unstriped" Plethodon. These
salamanders have been placed into three species groups: the...

Earthworms are capable of osmotic and ionic regulation while
living in a dilute balanced salt solution. When transferred from soil
to pond-water (PW) their body weight increases by 15 percent due to
a net uptake of water.
This results in an...

This paper is a study of various linear Metal-Oxide-
Semiconductor integrated circuit configurations with the
goal of improving their operation. The operation of MOS
devices is covered including their use as load devices
to replace diffused...

A focused Q-switched neodymium-doped glass laser with power
levels ranging from 1-6 MW and with a 50-nsec halfwidth, was used
to vaporize copper metal. Experimental measurements showed that
the amount of material vaporized away from the target was...

The use of the exponential-transfer-characteristics of a transistor
junction as a means of giving a logarithmic sweep calibration to a
sampling oscilloscope is presented. The prior work in logarithmic
converters leading up to the use of the...

The critical buckling load for round tapered columns with variable
end fixity is presented. The theory used is presented together
with the general solution for the resulting differential equation. This
general solution is solved by use of a...

Density measurements of molten solutions of thallium
and tellurium have been made over the temperature range
220 to 650°C and the composition range 31 to 69 atomic
per cent thallium. The Archimedian method was employed
since it is readily...

Twelve chemicals (Busan 72, Chloropicrin, Dacthal, Dexon,
Duter, EP 161, Lanstan, Methyl bromide, Phaltan, Vapam, Vidden D,
Vorlex) were tested to determine their effect on populations of certain
important soil-borne microorganisms including the...
