The formation of cytosine hydroperoxide was detected in
aqueous cytosine solutions irradiated with Co-60 γ-rays at pH 2.
The nucleotide of cytosine, cytidylic acid, forms a hydroperoxide
which was detected in neutral solution. The stability of the...

Acidity distribution within any given soil profile is dependent on
mineralogical make-up of the parent material as well as environmental conditions prevalent during the weathering history of the soil.
An experiment was designed to study the...

In previous research, bromacil gave good performance when
it was applied in early fall with fairly dry soil conditions and before
the fall germinating weeds had started growth. On the other hand,
if bromacil was applied in late November, December,...

A design for an x-ray machine to be used as a visual aid for the
instruction of x-ray theory and x-ray machine operation has been
presented. From this design an x-ray machine was constructed and
tested.
Components used in an x-ray machine have...

The derivation of coefficients for the transfer functions of maximally flat time-delay networks generally begins from an infinite
series approximation of the ideal transfer function. This thesis presents two alternative methods that are...

A study of stress transfer near the ends of the whisker in a simulated whisker reinforced composite material was conducted by using
photoelastic techniques. The composite material studied was
αAl₂O₃ whiskers in an aluminum matrix. The photoelastic...

Levels of activity of glucose-6-phosphate- , 6-phosphogluconate- , and isocitric- dehydrogenase were measured in the
soluble and particulate fractions of heart, brain and liver at
several ages throughout the development of the chick embryo....

This study was designed to reveal the outcomes of participation
in science project activities such as Science Fair projects among
ninth grade science students in Multnomah County, Oregon, during
the second half of the 1963-1964 school year.

The "Teepee" type wood residue incinerator, similar to
many other sources, requires sampling at the point where the emissions enter the atmosphere. Because the location of the emission
point is hazardous and unpleasant for the operation of a...

This work shows how a new design in a load cell can be built
using the principles of photoelasticity. From photoelasticity one
knows that fringes denoting the stress pattern can be observed in a
plastic model viewed in a polariscope. Through...

A brief history of X-ray control methods is presented, and
the instrumentation requirements and physiological considerations
pertaining to an automatic X-ray control system are discussed.
The latter half of the thesis describes the design and...

Three inbred and relatively unrelated lines of Hereford cattle
(1. Lionheart, 2. Prince, and 3. David) developed at the Corvallis
branch of the Oregon Agricultural Experiment Station as part of the
W-1 project of the Western States were crossed...

By salt depleting the animals or by injecting them with
aldosterone, I was able to increase the active transport of sodium
across the isolated skin. The potential difference was increased
by 37% and 43% respectively and the net sodium flux by 69%...

In order to understand more about insulin behavior in solution,
Zn-free insulin was modified by adding polyglycyl chains to the
molecule and then observing the effect of the peptide on the behavior
of insulin under various conditions.
NCA-glycine...

The problem that is attacked in this paper is that of analyzing
and predicting the response of a balanced detector when it is driven
by short, periodic bursts of RF energy. There is, however, sufficient information provided to extend the analysis...

It has been reported that cyanide inactivates the succinate dehydrogenase activity of HMP toward cytochrome c, oxygen, methylene blue and DCIP. In the present study, it was found that cyanide
also solubilizes the SDH from HMP, this is reflected by...

In this paper we present a model of Non-Euclidean geometry
in three dimensions. This will show that the axioms of Non-Euclidean
geometry are consistent if Euclidean geometry and, hence, arithmetic
is consistent. However, the model is incomplete...

The successful agriculture of the United States is in part the
result of the productive effort of the agricultural experiment stations.
Students from different countries, throughout the world, have visited
the United States to learn and observe...

The purpose of this study is to determine if the problem of
scheduling instructors to classes can be formulated as a linear
program involving integer variables limited to values of zero and
one. Once such a formulation is accomplished, attempts at...

Although short-tailed weasels (Mustela erminea) are important predators of small
mammals, little is known about their space use, habitat selection, or vulnerability to predation in
North America. To evaluate the effects of forest management and...
