Data from the southern Cascade Mountains of
Oregon has been collected for application in computer
analysis of snowfields. Vegetation type, canopy
cover, slope, aspect, insolation, and snowfield
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...
Commercial thinning young growth forests is an increasingly
important silvicultural technique for improving second growth
management of Douglas-fir stands. Research aimed at advancing the
efficiency of skyline logging operations in small wood timber stands
is essential in order to make thinning these young stands economical.
The purpose of this study...
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.
Flow...
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...
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...
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...
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
expression...
In this research a model is developed to predict population for relatively
rural areas experiencing rapid economic development. Of the many
ways to predict population size, in this research a "demographic-economic"
model is chosen for use. The economic variables which aid in projecting
population are total employment, and net changes...
In an attempt to provide a practical means to measure the information
processing capacity of a real-time digital processing system a
theoretical framework, the Real-Time Schemata, whose basis is a
schematic description and a measure of "useful information," is presented.
The description applies to processes that would typically be
implemented...
The sensitivity of Bacteroides nodosus, causative agent of sheep foot rot, to 24 selected antimicrobial agents was tested. Many contaminants ordinarily associated with foot rot lesions were sensitive to lincomycin while B nodosus demonstrated resistance to this antibiotic. A concentration of 1.08 μg of lincomycin/ml of basal medium optimally inhibited...
A method of calculating decay heat is presented which is a simplification of existing calculational methods, the summation method in particular. The method involves the assumption that one physical process, neutron capture, is negligible in order to simplify the governing physical equations. A Greens function is derived and the decay...
Nine Ca-Al-rich inclusions and one olivine inclusion
from Allende meteorite were studied for Ti, Al, Fe, Mg, Ca,
Na, Cl, K, Sc, V, Cr, Mn, Co, Ni, Zn,Hf, W, Ir, Au, Ta,
and Re -via INAA (instrumental neutron activation analysis)
and REE, Ba, Sr via RNAA (radiochemical NAA). The inclusions...
