An improved procedure for the preparation of β-(3-cyclohexenyl) propionic acid from 4-vinylcyclohexene was developed. The
Friedel-Crafts cyclization of β-(3-(3-cyclohexenyl) propionyl chloride
with aluminum chloride was shown to give one bicyclic...

The purpose of this paper is to show that arithmetic
is consistent if Euclidean geometry is. Specifically, a
model of Peano's axioms [2] is defined in the space of
Euclidean geometry, where Hilberts axioms [3] are taken
to be the axioms of...

Members of the family Simuliidae were studied in a single,
confined drainage system. In addition to determining the occurrence
and distribution of the species present, biological and ecological
observations were made. Specific measurements and...

Eleven small Mesozoic plutons crop out within a 76-squaremile
area of the southern Seven Devils Mountains in west-central
Idaho. The plutons are divided into a mafic suite, an older granitic
suite, and a younger granitic suite on the basis of age,...

Verticillium wilt of hops in Oregon, caused by Verticillium
dahliae Kleb., was first reported in 1956. Later, V. albo-atrum
Reinke & Berth. was also isolated from infected hop plants, and thus
both species of the fungus were shown to be the causal...

Glucose metabolism of phage-infected Streptomyces griseus
was examined by using the specific radioactivities of the amino
acids from the extracted protein of the host and phage as an index
of the catabolic pathways of glucose metabolism....

Considerable evidence exists to suggest the notion that selected
personality traits may be related to specific aspects of academic
achievement. This study was directed toward the investigation of this
relationship in the case of non-science majors...

The F₂ progeny from a diallel cross involving seven winter
wheat parents along with the parents were grown at the Hyslop
Agronomy Farm near Corvallis, Oregon to determine the influence
of three plant densities on gene action estimates for yield...

From a population of cells of Pseudomonas aeruginosa sensitive 33 parts per million (ppm) and 0.1 mg per ml of quaternary
ammonium (QAC) and chloramphenicol respectively, pure strains
resistant to 750 ppm and 50 mg per ml of these antibiotics were...

This paper investigates a particular bridge construction technique
which could result in a significant torsional moment. The
structural member under consideration is a prestressed concrete
girder for which no torsional consideration is made....

The cabbage flea beetle, Phyllotreta cruciferae (Coleoptera:
Chrysomelidae) was introduced into the United States from Europe
during the 1920's and 1930's. It was described as a new species,
P. columbiana, native to North America by F. H....

A study of the effect of mixing on the oxygen uptake rate of
estuarine bottom deposits is presented. The method of study involved
the mixing of samples of bottom deposits with the overlying water to
result in concentrations of suspended matter in...

Herbicides were tested for the selective control of bentgrass in
Kentucky bluegrass turf under three levels of competition. Best control
in zero competition was obtained with a winter treatment of
bromacil at two pounds per acre. Under...

The purpose of this study was to investigate the relationship between
physiological maturation and the intrapersonal relations of adolescent
girls. The Interpersonal Check List provided the measure of
self concept and ideal self concept for each...

A two-dimensional perturbation theory computer code,
PERT-IV, has been developed that will calculate reactivity
coefficients, the delayed neutron fraction, and the neutron
generation time.
The program uses the output flux and adjoint
flux from...

Four to six one-gram specimens separated by a distance of
several inches were obtained from each of 23 large chondritic
meteorites (approximately 1 kg each) representing the olivine bronzite
(H5), olivine hypersthene (L6) and enstatite (E5)...

The presence of diacetyl in sufficient concentrations to cause
off-flavor in beer is a serious economic problem affecting the brewing
industry. Research was carried out in an attempt to provide an
industrially acceptable method for reducing...

In this paper the characteristics of multi-conductor transmission
lines have been investigated for a variety of termination conditions
by using the differential equations and matrix methods.

By various experiments, it has been found that the response
of real materials to external forces is, in general,
nonlinear in character. In classical continuum mechanics,
the use of ordinary measures of strain have forced the
constitutive...

This dissertation deals with end and side launching of marine
vessels. Its object is three-fold: first, to review several successful
techniques of launching and to describe the problems involved;
second, to derive and explain the calculations...

Several biochemical tests were studied to determine their
correlation with coagulase activity. The lysozyme test was in perfect
agreement with the coagulase test for the strains studied.
Mannitol fermentation and egg yolk lipase tests were in...
