Nitrogen is a contaminant of niobium and tantalum adversely
affecting the workability of the metal. With recent interest in the
refractory metals, one problem the chemical analyst must solve
is the accurate determination of nitrogen in niobium and...

Partial purification of diamine oxidase from pea seedlings,
Pisum sativum, was accomplished by homogenization of 8-10 day
etiolated epicotyl tissue, followed by ammonium sulfate fractionation
and DEAE Sephadex column chromatography. The...

The study was conducted on the Ochoco National Forest in
central Oregon. Vegetation-soil relationships were evaluated for the
following objectives: 1. Develop a sound ecological foundation on
which total land management decisions may be based. 2....

Primary monolayer cultures of chick renal epithelial cells
grown on plastic coverslips were reversibly dissociated with the
chelating agent ethylenediaminetetraacetic acid (EDTA). The cellular
responses during dissociation and reaggregation in...

In the field of herpetology, most studies of homing have been
carried out with anurans and, to a lesser degree, reptiles. Studies
of orientation and navigation in urodeles have been limited to a few
brief notes and the extensive investigation of...

The capabilities of the coagulation-filtration process for virus
removal were evaluated by constructing and operating a one step,
2 gpm coagulation-filtration pilot plant. Multi-media filters were
used without pre-coagulation and sedimentation. A...

Consider a transformation group G operating on a space X
and a G- invariant function f defined on a G- invariant subset of
X. By imposing suitable conditions on X, G, f and A, the
author derives sufficient conditions for extending f invariantly...

Assay conditions and analytical methods established for the
study of epoxidation of the insecticides aldrin and heptachlor, by
rat liver microsomes have been employed to study the same reaction
catalyzed by trout liver microsomes. At 37° C and pH...

Creep in wood has been observed since 1833 but only recently
has it been studied quantitatively. The aim of this paper is to study
the time-dependent deflections of Douglas fir, Coast Region beams
in bending and shear modes. The general method of...

There are essentially no publications dealing with the skin toxin
of Taricha granulosa. This study has undertaken investigations with
this toxin in an attempt to determine its potency and its effect on the
newt's potential predators.

Phoma menthae Strasser causes black lesions and cankers on
stems and rhizomes of Mentha piperita L. The fungus was isolated
from infected rhizomes and stems.
The optimum temperature for growth of the fungus in culture
was between 20-25°C; little...

This thesis studies the question of unique factorization in
quadratic integral domains. In the first chapter many general
theorems and definitions from algebraic number theory are introduced.
The second chapter considers an integral domain in...

The objectives of this study were: a) to obtain and evaluate
equipment for bio-acoustical analysis for this work and for future
work in the analysis of insect sounds, b) to study the acoustical and
sexual behavior of Acheta domesticus L., and c)...

We analyze the convergence to equilibrium of solutions to the nonlinear Berger plate evolution
equation in the presence of localized interior damping (also referred to as geometrically constrained
damping). Utilizing the results in [24], we have...

A report in the literature suggesting that the use of cottage
cheese dressing cultured with S. diacetilactis would afford enhanced
flavor and shelf life in the finished product prompted this study to
examine reasons for its effectiveness. The...

Iodoacetic acid and diphenylamine were used in this study to
elucidate the mechanisms of resistance of Micrococcus radiodurans
to radiation. This organism, a gram positive, non-spore forming,
salmon-pink, tetracoccus has a LD₅₀ of 213,000 R when...

Various properties of the integers in two quadratic number
fields will be examined. Among these will be the property of unique
prime factorization. When unique prime factorization breaks down,
as will be the case in one of the quadratic number...
