The effect of lifting Douglas-fir seedlings from the nursery bed
and replanting them, either immediately or after storage at 2 C for
periods up to six weeks, was investigated through a series of experiments
conducted in controlled-environment chambers and under field
conditions. Seedlings lifted prior to December, or after buds...

This thesis discusses the design and evaluation of an instrument
that can detect known signals in noise. This detector uses
two integrators to sense a difference in the received signal between
half-cycles of the known signal.
The detector is useful for sensing signals in the approximate
frequency range of 100...
This study involved an investigation of lactic streptococci which
had irreversibly lost ability to produce the high levels of acid in milk
necessary during the manufacture of certain fermented dairy products.
The slow acid producing mutants studied were obtained from
a normal acid producing strain by natural selection following induction...
The relative conductance at room temperature of a solution in
kaolin membranes was studied as a function of the volume fraction of
the membrane. The resistances of the membrane and of the solution
were measured for various volume fractions, and the conductance of
the membrane relative to the solution was...
Ion exchange chromatography methods which have been
developed in recent years appear to offer a sensitive technique that
can be utilized very advantageously in studies on various proteins
and their properties. The application of such a procedure for the
successful fractionation of bovine sarcoplasmic proteins should stimulate
interest and research...
Thermal expansion is one of the most frequently measured
physical properties of materials. One of the important methods
of detecting and measuring these changes is dilatometry, which
is measuring the thermal expansion of the specimen and relating
the specimen's expansion to its temperature.
Four major types of dilatometers are commonly...
Dihalocarbenes have been generated by thermal decomposition
of sodium trichloroacetate and tribromomethylphenylmercury, and
give mono dihalocyclopropyl adducts with steroid dienes. Such
compounds offer an easy starting point for the synthesis of unusual
derivatives of potential biological interest. Under the same conditions,
however, addition to non-conjugated double bonds does not
take...
The purpose of this study was to determine what insect species
occurred in waste water facilities at Corvallis, Oregon, and to
correlate these species with the chemical, physical, and biological
features common to these facilities. Data collected on a routine
basis included dissolved oxygen, temperature, algal density, and
insect population...
As indicated by the title, this thesis generalizes the Main Inertia
Theorem of Ostrowski and Schneider [8]. The first three results
concern the formation of a polynomial function f(A, A*, H) so that
the existence of an hermitian H for which f(A, A*, H) is positive
definite is a necessary...
The comparative values of impedance and resistance to reactance
ratios are important parameters in determining the load
capacity of an interconnection of power transformer, called a bank.
The full design capabilities of parallel or three-phase connected
transformers cannot be utilized unless the following constraints are
applied.
1. All transformer voltage...
In 1959 Kitagawa discovered and isolated the amino acid,
canavanine. Since its discovery much interest has been centered on
this amino acid because of its biological aspects; e.g. canavanine has
been shown to inhibit the growth of bacteria, viruses, protozoa, and
cancer cells.
The occurrence of canavanine is widespread in...
The purpose of this study was to study in some detail
host factors which influence the population dynamics of
bark beetle. The dissertation objectives were to ascertain
the applicability of utilizing osmotic pressure
values and relative turgidity values of phloem tissue as
indicators which reflect upon the physiological profile
of...
A mechanism is a constrained kinematic chain composed of
gears, links, cams, or the like. Mechanisms are the building blocks
of all machines, and, as such, their evaluation is of considerable
importance to the mechanical designer. Because the mathematical
analyses of systems with four or more moving members has been...
The purpose of this investigation was to modify the procedure
of Bills, Khatri and Day for use in the development of a suitable
method for determining the quantitative distribution of the free fatty
acids (FFA) in normal, heated, and rancid milk and milk fractions
The method consists of extracting the...
A series of four animal experiments utilizing 129 pigs
and associated laboratory studies was conducted to study the causes
of the lowered performance on high barley rations fed to swine. Previous
work at this Station has shown barley to have a value of 80-85
percent of corn for swine, and...

Correlation was sought between abundance of mycorrhizae on
Douglas-fir seedlings and their survival in field plantations.
One possible indication of dormancy desirable for lifting from
nursery beds could be the varying seasonal abundance of ectotrophic
mycorrhizae on roots of seedlings. No direct correlation between percentage
of mycorrhizae and survival in...
Oregon State University operates a World-Wide Standard Seismograph
Station at Corvallis (COR) and a seismic station at Klamath Falls (KFO),
Oregon.
The Corvallis station includes three short-period Benioff seismographs
(To = 1 sec, Tg = 0.75 sec), three long-period Sprengnether
seismographs (To = 30 sec, Tg = 100 sec), and...

Convenience in meal preparation is one of the chief advantages of homemade ready-mixes. Usually there is a saving of total time and labor in measuring and mixing. Some types of mixes save more time than others.
You can make the mixes when you have the time.
You can select a...
Three realms of deposition, Marine, Fluviatile, and Marine-
Fluviatile, are recognized in Yaquina Bay, Oregon, on the basis of
sediment texture and mineralogy. The Marine Realm extends 1.5
miles into the entrance of the estuary and is typified by normal
marine salinity and vigorous tidal action. Sediments of this realm...
Incipient boiling and burnout heat fluxes were studied for sub-cooled forced convection annular flow. Small wires varying from 0.010
to 0.020 inch in diameter were used as the inner core of the annulus
and a one inch ID glass tube 24 inches long was used as the outer tube.
This...
The influence of pH (titration method) and of salt concentration
and drying (drying method) upon the formation of synthetic AI, Fe,
and Mg interlayers in montmorillonite and vermiculite was investigated.
Interlayer formation was evaluated by X-ray diffraction
measurements of basal spacings using a natural chlorite for comparison.
The titration method...
This study was designed to answer six basic questions
in order to find some selected beliefs and practices of
home economics teachers concerning enrollment in home economics.
These questions were:
1. What are the beliefs of home economics teachers
concerning:
a. the students who can profit from home
economics?

Although much information is available on lipids in serum and
red cells, only limited data have been reported for white cells and
platelets. In a recent investigation in this laboratory, the concentrations
of cholesterol in the several blood fractions were compared.
The high amounts of cholesterol found in white cell-platelet...
Solar radiation intensities, incident to the sea surface off the Oregon
coast, are measured and compared. Simplification of some physical
and biological problems can be anticipated if the average radiation
received over a broad segment of ocean can be accurately indicated
by the amount recorded at the land station.

Eight experiments, two with poults and six with chicks, were
undertaken to determine the requirement for supplemental folic acid
as related to protein level and major protein source. Protein levels
for chicks and poults were 21, and 28 or 28 and 32%, respectively.
Major protein sources were soybean meal, fish...
Preparation of a cytochrome c-cytochrome oxidase complex
was achieved, using crystalline beef cytochrome c and purified
cytochrome oxidase from beef heart muscle, or from the
Keilin-Hartree preparation. Succinate oxidase was reconstituted
with the complex.
A mixture of cytochrome oxidase, solubilized with nonionic
detergent, and excess cytochrome c was exposed to...
The purpose of this study was to compare the performance of
