Many changes have been taking place in Oregon's agriculture.
Average size of farms has increased. The trend is toward fewer
but larger, highly mechanized farms, leading to changed demand
for farm machinery and consequently changes in farm machinery
firms to meet the changing demands of farmers. In general, the
research...
This research design was based upon the mutual relevance
between the fields of education and anthropology to cause cognitive
cultural awareness by the teachers of adults as well as visibility
within the Mexican American ethnic group.
Specifically the purpose of this study was twofold:. (1) to
determine whether the adult...
Straw has many uses, as feed, roughage, animal bedding, but
these requirements are not sufficient to utilize the available production.
In areas where grasskseed is produced, post-harvest straw is
burned in the field to help prevent crop disease the following year.
This treatment is very wasteful in terms of straw...
Investigations were conducted to determine whether the low molecular weight nitrogen compounds and the extra protein complex of bovine psoas major muscle were altered during a 12-day aging period.
Electrophoretic studies of soluble proteins either before or after gel filtration on Sephadex G-25 columns indicated that the soluble proteins were...
Of the common adult lanternfishes found off Oregon, two
species have fat-invested swimbladders (Stenobrachius
leucopsarus Eigenmann and Eigenmann 1890 and Stenobrachius
nannochir Gilbert 1891), two species have reduced swimbladders
(Lampanyctus ritteri Gilbert 1915 and Lampanyctus galis
Gilbert 1891), two species have gas-filled swimbladders
((Protomyctophum thomp soni (Chapman 1944)) and (Protomyctophum...
The purposes of this study were to determine the effects of
temperature, nutrients, growth regulators, and culm detachment
during seed development on ryegrass seed dormancy and weight.
The effects of storage temperature on seed dormancy were also
studied.
Seed dormancy of annual (Lolium multiflorum Lam.) and
perennial (Lolium perenne L.)...
Environmental swabs and meat samples from two of three seafood
processing plants sampled on the Oregon Coast were found to
contain Salmonella. Although these enteropathogens were not isolated
from the finished products, the danger of contamination is great
since the processing received by many seafoods is not designed to
yield...
The purpose of the research was to investigate the chemical
composition of five starches and the physical characteristics of their
respective starch pastes as these properties relate to the characteristics
of starch-structured breads. Starch-structured breads were prepared
with five starches, corn, wheat, potato, arrowroot and waxy
maize, used as granular...
Current observations were obtained at three locations forming
a cross section along 70°34'W longitude in Long Island Sound. Fifteen
days of data were selected from each series so that nearly
simultaneous observations were used in the analysis.
Elementary statistics were computed for the data prior to
performing a least squares...
Myelin formation in the chick embryo sciatic nerve was examined
during development by analysis of three myelin lipids (cholesterol,
phospholipids, and cerebrosides) and of a myelin related
enzyme (2', 3'-cyclic AMP 3'-phosphohydrolase). The role of the
Schwann cell in controlling the synthesis of these myelin components
was studied by in...
The properties of evaporated aluminum-oxide films were investigated. The characteristics of MOS devices
made with single-layer aluminum-oxide films and double-layer
films which were made by evaporating aluminum oxide
over thermally-grown silicon dioxide as gate insulation
have been investigated. Vacuum-evaporated aluminum oxide
has features which are suitable for fabricating MOS devices....
A double-beam photometer was designed and built employing photon counting to give a direct digital readout. It was evaluated as an analytical instrument with special emphasis on pulse recovery time, pulse interaction and instrument settings. An equation is developed to explain pulse interaction in event counting systems.
This thesis presents an introduction to Marketing Research concepts,
relates Operations Research to Marketing Research and discusses
the limitations of each. An Information Theory approach based
on Shannon's fundamental theorems and extended by Kunisawa is
applied to one-factor and two-factor marketing problems.
The objective of one-factor information channel models is...
The specific activity of ⁶⁵Zn (nanocuries ⁶⁵Zn/g total Zn)
was determined in various organs of the common coastal mussel,
Mytilus californianus Conrad, collected from six locations along
the Pacific Coast. These organs included the gills, mantle, foot,
reproductive organs, adductor muscle, and viscera. After ashing
and dissolving with nitric acid...
Diffusion coefficients for isopropyl alcohol-air, isopropyl
alcohol-argon, isopropyl alcohol-mixture of argon 1
: air 1, isopropyl
alcohol-mixture of argon 1
: air 2, and carbon tetrachloride-air system were determined, using an Arnold cell technique.
The measured
carbon tetrachloride-air system diffusion coefficient was compared
with previously measured values to verify the...
Experiments were conducted to determine identification methods
that could be used to differentiate annual and perennial plant types within
the species Poa annua L. Thereafter, Poa annua plants were collected
from numerous turfed areas in three Northern Pacific Coastal
regions and identified as annual or perennial biotypes.
It was found...
Natural convection heat transfer in air between two vertical
plates 38 by 24 inches was investigated in this work with spacings
between the plates of 0.625, 1.0 and 1.75 inches. One plate was isothermal
and the other adiabatic.
To measure the point velocities in the air layer a very thin...
