The purpose of this work was to design a system for measuring
the velocity of a powder actuated fastener or drivepin during penetration.
This system would provide a tool for further investigation
into drivepin penetration characteristics. The main characteristic
of interest is the instantaneous acceleration from which the forces
on...
This study focused on the relationship between parental attitudes
and the conscience orientation of children, testing the hypotheses that
(1) parents who had children with an external conscience orientation
would show significantly greater disparity between their independence
granting and achievement inducement attitudes than parents whose
children had conventional or humanistic...
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...
The herbicides Diquat (1, 1'-ethylene-2, 2'-dipyridylium
dibromide), Paraquat (1, 1'-dimethyl-4, 4'-dipyridylium dichloride),
and Gramoxone (1, 1'-dimethyl-4, 4'-dipyridylium dimethyl sulphate), and the spreader X-77, a mixture of alkylaryl-polyethylene
glycol, free fatty acids and isopropanol, were tested by
several soil microbial methods in an attempt to find out if concentrations of these...
Samples of Russet Burbank and Kennebec seed potatoes
used by Oregon growers were grown in replicated plots at
Klamath Falls, Prineville and Corvallis. Observations
were made of total yield, yield of U.S. No. 1 tubers and
number of stems produced per plot.
Total yields of the Russet Burbank variety were...
Forest associations, secondary succession, and relationships
of plant communities to Roosevelt elk were investigated. Stratification
of vegetation into ecological units and an understanding of secondary
succession by habitat-type were a necessary first step in investigations
into browsing of conifers by elk. The study was jointly conducted
by the Oregon State...
Description of anuran larvae with the use of staging tables is
a common practice in the study of frog life-histories, but there has
been no previous description or table of Ascaphus larvae. In comparing
Ascaphus larvae to a simplified staging table for anurans it
was found that these larvae vary...
Samarium

were
studied
by
chronopotentiometry
in
a

eutectic.
Tungsten

were
used
to
avoid

were
observed
which
prevented

A knowledge of the time rates for intermediate reactions
during the photolysis of nitrogen dioxide enables one to deduce the
possible intermediate reactions which are responsible. An experiment has been devised and constructed which will measure the time
rates for photochemical reactions occurring in ranges of one micro
second to...
The effects of coumestrol on the uterine weight, uterine fluid
imbibition, uterine nucleic acid content, adrenal weight and body
weight of female rats were studied. Daily doses of 20 micrograms
of coumestrol per 0.1cc propylene glycol were administered subcutaneously
to spayed rats following a seven day recovery period,
for durations...
