Research on the application of soluble, metal chelates for
water tracing using thermal neutron activation analysis for tracer
determination has led to the development of several tracers with
promising solution stabilities (conservative behavior) and determination sensitivities. The solution stabilities of the ethylenediamine
tetraacetic acid (EDTA) and the diethylenetriamine pentaacetic acid...
In this paper a direct, constructive proof of the equivalence of the Normal Algorithm and Turing machine using the Turing machines NAS (Normal Algorithm Simulator) and NAC (Normal Algorithm Converter) is presented. The Turing machine NAS can simulate any particular Normal Algorithm, and NAG can convert the quintuples of a...
The purpose of this thesis is (1) to study two Oregon communities
and to report data related to their concepts of community
education and (2) from this data, to develop guidelines for the planning,
organization, and implementation of comprehensive community-wide
educational programs. In accomplishing these purposes, it is
hoped a...
A study was conducted at the Pacific Cooperative Water Pollution
and Fisheries Research Laboratories, Oregon State University,
to determine the effects of pentachlorophenol (PCP) on the early developmental
stages of the steelhead trout (Salmo gairdneri). Experiments
were performed from May, 1965, through May, 1968, on the
survival, growth, and bioenergetics...
This study investigated several physiological aspects of the
water economy of the Sage Sparrow, Amphispiza belli nevadensis,as
they relate to the ability of this species to inhabit xeric desert environments.
When maintained in captivity on a dry diet without
drinking water, Sage Sparrows gradually lost weight and died. During the...
The uptake, retention, and distribution of ⁶⁰Co, ⁶⁵Zn, ⁸⁵ Sr, and ¹³¹I was examined in the Rough-Skinned Newt (Taricha granulosa). Each of these radionuclides is a possible contaminant of the freshwater environment and, thus, is of importance in radioecology. The newts were maintained singly at 10° C in an unfed...
The theory and ways of applying a new electroanalytical detectior
method were developed. The method, called galvanovoltammetry,
consists of the measurement of current from the bipolar electrode of
a three electrode cell which consists of a working electrode and a
counter electrode, between which a constant current is applied, and...
Internship and field experience programs have been used to
prepare educators for roles in public school teaching and administration;
junior college and university teaching, and adult education.
Based on a survey of the literature it is apparent that little attention
has been given to the role that these internship and...
This investigation was designed to study articulation between
Oregon secondary mathematics programs and college mathematics at
Oregon State University. Three main facets of the problem were
studied:
1. The relationship of several factors to the CEEB Level I
Mathematics Achievement Test score.
2. The feasibility of a discriminant function as...
The electromagnetic field in a cone of arbitrary slant
height with a symmetrically placed time harmonic ring source is
studied. Through the use of the modified Helmholtz equation as
an intermediate, we obtain the solution of the semi-infinite
cone directly from the finite cone. To demonstrate the need
for the...
The pathogenicity of A. flavus on alkali bee larvae was studied
using sample materials from three nesting sites of these soil
inhabiting bees along the Oregon-Washington state line. Soil
saprophytes of the biosphere of the alkali bee were also studied.
Field observations and direction of soil cores from bee beds...
The presence in rat liver microsomes of an enzyme system
which demethylates N-methylhydrazines and azo compounds to formaldehyde
has been reported. Some of the compounds found to be
substrates were monomethylhydrazine, N-isopropyl-α-(2-methylhydrazino)-
p-toluamide and the azo derivative of the latter hydrazine. This
enzyme can be classified as a mixed function...
Flower bud influence on rootability of Rhododendron shoots was
assayed by rooting leaf-petiole cuttings. Monthly samples of an easy-and
an intermediate-to-root cultivar showed periods of poor rooting
in the latter during flower development, although both rooted similarly
during bud dormancy. The decrease in rooting-potential following
flower initiation and development was...
The individual stocks of sockeye salmon that make up the
annual spawning migration to the Bristol Bay region of Western
Alaska are produced in the lakes and streams of ten major river
systems, which discharge into the bay over a shoreline distance of
120 miles. The hypothesis adopted in this...
