This thesis introduces a technique for approximating to a desired
degree of accuracy a linear parabolic equation of two spatial
dimensions with given initial data and prescribed boundary conditions.
The technique is generalized to non-linear...

This study was designed (1) to identify and describe young
homemakers' problems through expressed difficulties in homemaking
activities, (2) to investigate the relationship between the expressed
problem areas and the homemakers' length of...

Changes in educational programs should be implemented only
after a careful evaluation of the product. Information about the product
in education is often not available to planners of vocational education
programs. A follow-up study of former...

The object of this investigation was to determine a number of
physical constants for the crystals of two commonly used insecticide
compounds. The compounds chosen were Aldrin and Dieldrin,
which are chlorinated cyclodiene compounds. These...

Reproductive characteristics of introduced eastern cottontail
rabbits, Sylvilagus floridanus (J. A. Allen), were determined from
486 rabbits collected between January 1, 1968 and June 30, 1969,
near Corvallis, Oregon.
Sex ratios were 1:1 for all...

A study of the relative rates of benzylic hydrogen abstractions
from a series of meta and para substituted neopentylbenzenes by the
bromine radical and trichloromethyl radical at 70°C has been carried
out. Application of the Hammett equation...

Predetermining the ultimate capacity of piles driven into purely
cohesive soils and purely cohesionless soils involves, respectively,
the consideration of soil shear strength in a completely undrained and
a completely drained condition. For the...

The experiment was conducted at the Soap Creek farm ponds
near Corvallis, Oregon. Oregon Moist Pellet and Purina Trout
Chow at three different rates of feeding for each diet were used
to feed fingerling channel catfish stocked at the rate of 1,000...

There is an increasing body of evidence that the pineal gland acts
as a neuroendocrine transducer, translating neural information about
environmental lighting condition into hormonal information. In the
rat, light controls the production of...

The photolysis of the aqueous thymine system has been investigated
at 214 nm, 229 nm and 254 nm at room temperature. Products
of photolysis have been identified as hydrogen peroxide, 6-hydroxy-5-
hydroperoxy thymine and tentatively...

A need has existed for an in-depth structural analysis of penstock
bifurcations because they form an integral part of hydroelectric
power plants. Their geometrical complexity has prevented classical
structural analysis from providing an accurate...

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...

The spectrophotometric titration of the tyrosine residues,
their reaction with N-acetylimidazole, and the effect of pH on the
thermally induced conformational transition of ribonuclease T₁ have
been investigated. The results of spectrophotometric...

The concentrations of iodophor necessary to reduce the activity
of several metabolic enzyme systems 50 percent was used as the
basic approach in attempts to elucidate the mechanism of germicidal
action of iodine. For comparisons, a...

This thesis deals with the output statistics of nonlinear devices.
It develops the classical output autocorrelation function in two dimensions
and extends the theory to three and four dimensions. Closed
form solutions for the output correlation...

Verticillium dahliae Kleb. causes a wilt disease of peppermint.
Attempts to control the disease by soil fumigation, crop rotation,
flaming of stubble, and deep plowing have met with only limited success.
Development of resistant varieties through...

The wildland urban interface (WUI) delineates the areas where wildland fire hazard most directly impacts
human communities and threatens lives and property, and where houses exert the strongest influence
on the natural environment. Housing data...

Inhaled and intranasal corticosteroids (ICS and INS) are among the mainstays of the treatment for asthma and allergic
rhinitis, respectively, and also carry the potential to suppress the hypothalamic–pituitary–adrenal (HPA) axis. Several important...

The surgery technique of Gromov and Lawson may be used to
construct families of positive scalar curvature metrics which are parameterised
by Morse functions. This has played an important role in the study of the
space of metrics of positive scalar...

The most damaging foliar disease of pyrethrum in Australia is ray
blight caused by Stagonosporopsis tanaceti. The probability of growers
incurring economic losses caused by this disease has been substantially
reduced by the implementation of a...

Invasions have increased the size of regional species pools, but are typically assumed to reduce native diversity.
However, global-scale tests of this assumption have been elusive because of the focus on exotic species richness,
rather than...

We demonstrate remarkably strong nonlinear terahertz (THz) effects in an intrinsic GaAs wafer patterned with a nanometer-width slot antenna array. The antenna near-field reaches 20 MV/cm due to the huge field enhancement in the plasmonic...

Pants have become a seemingly necessary part of the average
American woman's wardrobe and may be worn for nearly every occasion.
However, many women have indicated that when conventional
methods of construction were used for pants-making, the...
