ground truth delineation are given consideration.
In addition, a procedure for transferral of data
onto Landsat imagery was derived.
Corn oil (CO) and Sterculic foetida oil (SFO) fed rats were
injected with [9, 10-methylene-¹⁴C]sterculic acid. Less than 1%
of the label was expired as carbon dioxide. The majority of the
label was excreted in the urine as short-chain dicarboxylic acids with
an intact cyclopropane ring. The major metabolites for...

The response of three hardwoods from Ghana and a hardwood and
three softwoods from the United States to liquid and gas-phase impregnation
was investigated. Impregnation with liquids included a sink-float
test in a water-glycerine solution and pressure treatment with a copper
sulphate solution and creosote under identical treating conditions.
The objectives of this study include: (1) analysis of Chamaecyparis
lawsoniana, C. taiwanensis, and C. formosensis forests including
the structure, composition, and dynamics of plant communities and
their environmental relationships; and (2) comparison of the temperate
Chamaecyparis forests of Taiwan and the Pacific Northwest with emphasis
on structural and successional...
A study was conducted to determine the heat transfer characteristics
of pin finned heat sinks in natural convection. Three pin
diameters were studied: 0.238 cm, 0.318 cm and 0.396 cm. The pins
were attached to the base in two arrangements, triangular and
rectangular, forming a horizontal array. Pin spacing was...
Esophageal fistulation, stomach content analysis, fecal analysis,
and ocular-estimate-by-plot are four of the most publicized methods
of determining the diets of large herbivores. The principal objective
of this study was to compare the relative values of each of these
methods based upon information collected from bi-fistulated (esophageal
and rumen) sheep...
The purpose of the study was to compare perceptions by faculty,
students and administrators of the campus environments of eight small,
independent liberal arts colleges in Oregon and to determine if similar
or like perceptions of the environment lead to greater vitality in each
of the colleges studied. In the...
The study measured and compared the philosophies of education of OSU graduates who are experienced teachers of vocational education and undergraduate vocational teacher trainees on an essentialist-progressive scale at OSU. The objectives of this study were to (1) determine if experienced teachers of vocational education and undergraduate vocational teacher trainees...
Between 1967 and 1973, California, Oregon,
and Washington all established state-wide systems for
the preservation of land in its natural state. These
set aside parcels of land may be termed as Natural
Area Preserves. The history of each state's public
systems, different establishment procedures, and
management policies are discussed.
The experimental measurements of the decay heat from
the products of the thermal fission of U-235 have been compared
with the OSU-proposed decay heat standard. These experiments
are intended to verify the decay heat calculational
methods and nuclear data files. The comparisons have
included the previous experiments reviewed by Perry...
Self-recording instruments were installed in the Drake Passage in February 1975. Approximately one-half were part of a short-term array (3 + weeks) and were all successfully recovered in March 1975. The remainder are part of the long-term array which was recovered in January 1976.
The short-term array consisted of 2...
The development of the energy crisis has caused the
use of depletable energy resources to be monitored quite
closely in the United States. Within the agricultural
sector, irrigation is a large user of energy, with the
potential of using many times more energy than all other
agricultural field operations. A...
A continuous amperometric monitor for aqueous sulfite solutions
has been developed employing the electro-oxidation of sulfur (IV)
in 0. 1 M sulfuric acid at a glassy carbon test electrode. The monitor
employs a hydrodynamic flow cell, in which the solution stream
enters the cell through an orifice impinging on the...
Baseline data for the first year of a two-year study to assess
the current status of ponderosa pine stands in southeastern
Montana relative to coal-fired electric power development are
presented. Sixteen permanent plots in pine stands were established
in eastern Montana, South Dakota, and Wyoming. Several characteristics
believed to be...
The purpose of this work was to develop a dynamic partial order model of II electrolyte solutions which avoids inconsistencies present in the Debye-1-Iuckel and 1n related theories. It is shown that our results are consistent with activity coefficient data in aqueous electrolyte solutions. The main features of our work...
The study had four objectives, the major one being the identification
of the common professional competencies for adequate performance
as a Baptist clergyman. A second objective was to determine
the common professional competencies needed by Baptist pastors and
ministers of education. The determination if significantly different
competencies were required for...

The genotype frequencies of one-year-old oyster spat
(Crassostrea gigas) from parents of known genotype, are compared
to the frequencies expected with Mendelian inheritance. The genotypes
are characterized at three enzyme loci, Aspartate amino-transferase
(AAT), Phosphohexose isomerase (PHI) and Leucine
aminopeptidase (LAP), and a general protein locus. In this study
PURPOSE OF THE STUDY
This study developed a model which identified mathematical needs
in various vocational technical programs. This model provides a
