In many areas of engineering and applied mathematics, spectral methods provide very powerful tools for solving and analyzing problems. For instance, large to extremely large sizes of numbers can efficiently be multiplied by using discrete Fourier transform and convolution property. Such computations are needed when computing π to millions of...
Self-interactions (effects of reinoculation with the same nematode)
in Meloidogyne hapla and Heterodera schachtii on Beta vulpris at
different levels of inocula with various population combinations were
studied. In M. hapla, the only significant increase of galls was
noted in treatments when 250+250 larvae were inoculated at 10-day
intervals. Longevity...
In recent years, many studies have focused on the molecular and biochemical mechanisms regulating the development of wine grapes. The course of grape berry development is directed by genetic design and is mediated by phytohormones, which regulate grape berry growth and development by orchestrating a complex network of interacting genes,...
The project herein described, presents the results of an investigation
in the relatively new and expanding field of computer stimulated
learning machines for use in pattern recognition.
A learning machine, one that benefits from its past experience
was devised in computer program form. It may be described as a
Piecewise-Linear,...
Biliary excretion has been of considerable interest in mammals
but has not been extensively studied in fish. To understand the
significance of biliary excretion in rainbow trout (Salmo gairdneri),
two studies were conducted.
The objective of the initial study was to evaluate the ability of
rainbow trout to excrete a...
Oil is notorious for its volatility. Often as an indicator for economic wellbeing, the commodity employs millions across the country. Entire communities in the western United States are centered around oil extraction, with employment, livelihoods, and revenues dependent on oil’s success. This combination of factors begs the question, how do...
Several experiments were undertaken to investigate the mechanism of
photodechlorination of pentachlorobenzene. The thermal methoxydechlorination
reaction of pentachlorobenzene was studied. In DMSO at 50 °C sodium
methoxide reacts smoothly with pentachlorobenzene to give three
tetrachloroanisole isomers. A second-order kinetic plot for this reaction is linear to
high precision, indicating that...
This study examines the impact of the recently constructed
limited- access highway, Interstate 5, on agricultural land in Linn
County, Oregon. More specifically it scrutinizes the quality and
quantity of the land relinquished to the highway right -of -way; the
effects on field boundaries, connectivity, mobility, drainage, land
use, miscellaneous...
