The preparation of 4-(3-hydroxypropyl) cyclohexanone and
of 4-(3-hydroxypropyl) cyclohexene and a number of their derivatives
as potential precursors of asymmetrically substituted bicyclo [3, 3, 1]
nonanes is described.
The ketone, 4-(3-hydroxypropyl) cyclohexanone, was prepared
from p-allylanisole by three different routes. Common to each
route was an initial hydroboration-oxidation followed by...
The purpose of this study was to statistically evaluate one kind
of new elementary science curriculum materials. The materials;
(1) are written at five reading levels to partially meet the reading
ability spread found in the intermediate grades, (2) provide ways to
stimulate class discussion, and (3) provide three levels...
The central purpose of this comparison was to determine the
congruence or difference between two teaching techniques, the television
method and the conventional lecture method as used in teaching
General Hygiene on the freshman college level at Oregon State University.
Sub-problems associated with this study were, (a) the development
of...
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 cyclization of 3-(3-cyclohexenyl)propanoyl chloride permitted synthesis of the unsaturated
ketone from 4-cyclohexene carboxaldehyde. The formation of
the bicyclo(3.3.1)nonane rather than a bicyclo(3.2.2)nonane skeleton...
A heat stable derivative of bovine serum albumin containing
300 residues of glycine added to 30 sites on the surface of the protein

This study is focused primarily on the development and evaluation
of the SUTOE (Self Understanding Through Occupational Exploration)
program in the State of Oregon. It cites the need for a relevant
curriculum for junior high school age youth, and reviews the philosophical

We investigate in this thesis, the problem of stability
of thermo-viscoelastic fluid flow between rotating
coaxial cylinders. By using the thermo-viscoelastic
constitutive equations given by Eringen, we reduce the
equations of motion into a form suitable for stability
analysis. The course of reduction which we follow yields
some interesting intermediate...
Annual ryegrass (Lolium multiflorum) a major grass seed crop

unfostered; second generation, unfostered; and second...
Oregon Biography Index is intended to serve primarily as a starting point in locating biographies of Oregonians. We have indexed 47 historical volumes which are either entirely devoted to biographies or have large self-contained biographical sections. The profiles in the books vary widely in accuracy and detail. Birth dates of...
Purpose of the Study:
The purpose of this study was to analyze, in the mathematics
classrooms, career-oriented verbal mathematics problems on the
achievement and attitude of the vocational mathematics student.
These career-oriented mathematics problems, used as advanced
organizers, were contrasted with mathematics word problems of a
more abstract and generalized...
The effect of the mutual inductances between the rotor coils of a synchronous machine on its defined reactances and predicted transients are investigated. Two linearized models of the machine are considered. One uses the Laplace-Transform approach, with minimum number of assumptions on the inter-coil couplings, in developing a model for...
In recent years the conversion of agricultural lands to more

Senecio jacobaea (tansy ragwort) is a poisonous plant responsible
for livestock deaths in the Pacific Northwest. Horses and cattle are
susceptible, while sheep are resistant to the toxic action of the
pyrrolizidine alkaloids which the plant contains. Hepatic enzymes
are responsible for the biotransformation of pyrrolizidine alkaloids
into tissue damaging...

An investigation of the correlation between a number of behavioral,
morphological and physiological parameters and dominance status of male
Ring-necked Pheasants (Phasianus colchicus) was undertaken. Dominant
males performed significantly more aggressive behaviors than
subordinates and a higher proportion of these behaviors was directed
toward distantly ranked subordinates. Animals could also...

Concerns about the possible reciprocal differences resulting from
systematic crossings of winter and spring wheat gene pools prompted
this investigation. If traits can be improved by simply reversing the
direction of a cross, then identification of the best female parent in
a cross would be helpful for breeding programs.

The behavior of six herbicides in soil was studied under controlled laboratory conditions. Sorption of bromacil, chiorotoluron and diuron was assessed by the batch equilibration procedure over a broad range of aqueous phase sorbate concentration. Linear equilibrium sorption constants (K[subscript p]) were slightly higher at 4° C than at 25°...
Recently several minimal perfect hashing functions far small static word sets have been developed. However, they are limited to sets of 50 words or less. In this paper, a Two Level Minimal Perfect Hash Function for large data sets is given. It partitions a large static set into small sets...
A study was conducted to compare snow accumulation and melt during rainfall in adjacent forest and clearcut plots in the
transient snow zone of the western Cascade Range in Oregon. Snow accumulation differences were determined by comparing the water equivalents of forest and clearcut snowpacks. During rain-on-snow periods, energy balances...
Potash rate and source effects on tuber yield and quality
(hollow heart, size, and processing quality), and nutrient (K, Ca,
Mg, and C1) concentrations in petioles and tubers were evaluated in
three experiments, two in the Columbia Basin in Oregon (McDevitt and

Lodging in cereals can cause significant decreases in yield. It
is both a problem in susceptible cereal cultivars with a tall-stemmed,
weak-strawed growing habit and in lodging-resistant
cereal cultivars when they are grown under high-nitrogen, high-moisture
regimes. Plant growth regulators (PGR's) are chemical
growth retardants that offer a method of...
A variety of laser spectroscopic methods are employed in this

Six serotypes of calicivirus (San Miguel Sea Lion Virus types 4,6,7
and 13, Mink Calicivirus and Reptile Calicivirus) were plaque purified,
and two-dimensional gel electrophoresis fingerprints, of the ³²P-labeled
Ribonuclease T1 digested viral RNA, were performed for each serotype.
Fingerprints revealed several oligonucleotides with similar mobilities,
and therefore, possibly similar...
The cocondensation reactions of molybdenum trioxide vapor with
tetraalkoxysilanes, trimethylalkoxysilanes, and hexamethyldisiloxane
at -196°C were investigated. The products from the metal vapor
reactions of tetramethoxysilane, tetraethoxysilane, and tetrapropoxysilane
were characterized as molybdenum(VI)dioxodialkoxy compounds. The isolated compounds were found to be polymeric in the
solid state by bridging through alkoxide groups....
Freeze/thaw cycles are numerous in agricultural soils of the Pacific Northwest. Potential loss of soil by erosion is high whenever a soil thaws from the surface creating a saturated soil overlying an impermeable frozen layer. Field studies were conducted to investigate the effect of surface residue on soil freezing. Residue...
In the Northwest, two tree fruit production problems may be

Dietary intake data of 15 treated patients with
phenylketonuria (PKU) (7-17 years) and six control siblings
(6-14 years) were used to evaluate the effectiveness of
medical foods to balance energy, protein, vitamin B-6, and

A time-domain model was developed to predict the fluid/structure
interaction of a three-dimensional deformable body in a fluid domain subject to
long-crested finite amplitude waves. These nonlinear waves induce transient
motion in the body. In turn, the interaction of the body with the waves modifies
the wave field, causing additional...
Ribosomes are multicomponent macromolecular particles and
are essential for the survival of cells in all organisms. The ribosome's
universal function is to catalyze polypeptide synthesis through
translation of mRNA transcripts. Ribosomes from Escherichia coli,
eubacterial organisms, have a sedimentation coefficient of 70S and are
composed of 30S and 50S ribonucleoprotein...
The parallelization and vectorization of Monte Carlo algorithms for modelling
