The system of partial differential equations which governs the
motion of a Newtonian fluid has been known for over a century. Yet,
due to the complexity of the equations, an analytical solution is known
only for a few simple geometries or a few...

A sensitive ion chamber-electrometer system was used to determine
the Oregon State University TRIGA III reactor's ⁴¹Ar production
rate as a function of steady state reactor power and production of ⁴¹Ar
due to reactivity pulses up to $3.00. The...

Petroleum mulch applied on the soil surface over a row of
planted seeds promotes a more rapid and a more uniform germination
of seeds, enhances elongation of seedlings and in some cases increases
the yield of the crop. The beneficial effects of...

The purpose of this study was to test in practice the perceptual
field approach learning theory with students identified as slow
learners. The essential aim was to achieve significant improvement
in the self adjustment of the students while not...

The investigations were based on a complete diallel cross
among three inbred lines of Suffolk sheep. Line of sire effects were
assumed to be an estimate of general combining ability effects while
sire x dam interaction was assumed to be an...

The frequency of aphid transmission of cucumber mosaic virus
from diseased plants at different times after inoculation was determined.
A cycle of infectious virus was found. Primary leaves
of lima bean plants were inoculated mechanically when the...

New syntheses for 2-bicyclo(3.3.1)nonanone and 7-bicyclo-(3.3.1)nonen-2-one were developed. The saturated ketone was prepared
from phenol and acrylonitrile via a novel intramolecular
S[subscript N]2 cyclization process. A Friedel-Crafts...

An automatic, continuous analyzer has been developed which
is suitable for estimating the level of spent sulfite liquors (SSL) in
laboratory samples. The analyzer makes use of a version of the
Pearl-Benson, or nitroso method, and, in its present...

The primary purpose of this investigation was to characterize
the lipids of the spores and vegetative cells of Cl. botulinum. A
second purpose was to explore the possibility that lipids might serve
as a means of differentiating the chiefly...

An investigation of Mn uptake by five-day-old excised barley
roots revealed that a metabolically-mediated process was involved.
In short-term experiments, the rate of Mn absorption was comparable
to that of the macronutrient cations. Like other...

Selected nonionic surface active agents, incorporated in various
ointment bases, were applied to normal rabbit skin daily in an attempt
to determine their chronic toxicity. The dermatitic effects of these
surfactant preparations were evaluated by...

The enzymes and pathways involved in the catabolism of
glucose by several strains of Streptococcus diacetilactis, Streptococcus
cremoris, and Streptococcus lactis, commonly called the
lactic streptococci, were studied. The presence of aldolase,...

The fatty acids of coho salmon were identified and then a study
was conducted to determine the effects of exercise on the fatty acids
of salmon forced to swim against water velocities of 52, 54, 56, and
59 cm/sec, The shorter and lighter salmon...

Estimates of heritability and associations of tiller number,
seed number, seed weight, and seed yield were determined in two
groups of tall fescue. Group E was early maturing and had eight
parental clones, while group I was intermediate in...

Development of the posterior crossvein in crossveinless-like
strains of Drosophila melanogaster can be influenced by high temperature
shocks at specific times in pupal development.
Three sensitive periods were detected in age response studies

A facile route to bicyclo(2.1.1)hexanes was developed involving
the intramolecular photocyclization of 1, 5-hexadien-3-one to
bicyclo(2.1.1)hexan-2-one. A study of the chemistry of bicyclo-(2.1.1)hexan-2-one was undertaken. Deuterium exchange and...
