The purpose of the study was to determine the current status
of provisions being made to provide for appropriate utilization of
the increasing quantities of audiovisual equipment and materials
available in the public schools of Oregon. The ultimate objective of
the study was to identify activities and programs essential to...
Eight postemergence herbicides were evaluated to determine
their influence on the incidence and severity of take-all disease
caused by the fungus Gaeumannomyces graminis var. tritici in winter
wheat. Mecoprop ((+)-2-(4-chloro-2-methylphenoxy)propanoic acid),
difenzoquat (1,2- dimethyl- 3,5- diphenyl -1H- pyrazolium), dinoseb amine
(amine salt of 2-(1-methylpropy1)-4,6-dinitrophenol), and diclofopmethyl
(methyl ester of (+)-2-[4-(2,4-dichlorophenoxy)...
The two dimensional wavemaker problem on a finite domain is derived
for nonlinear waves. A numerical method based on the method of lines is
developed and applied to two test problems, the nonlinear surface pressure
distribution problem and the nonlinear full-flap wavemaker problem. The
solutions yield information about the fluid...
American meteorology was synonymous with subjective weather forecasting in the early twentieth century. Controlled by the Weather Bureau and with no academic programs of its own, the few hundred extant meteorologists had no standing in the scientific community. Until the American Meteorological Society was founded in 1919, meteorologists had no...
Following World War II, the United States enjoyed unprecedented power and prestige. The wartime alliance with the Soviet Union quickly collapsed amid mutual suspicion and fear, however, resulting in the Cold War. Science was a significant political component in that ideological conflict. In the United States, inspired by Franklin D....
Fresh ripe, cantaloupes were processed into juice and
juice concentrate. Processing trials were conducted on
fresh and frozen fruits with and without rind. The effects
of maceration enzymes and fining agents on yield and quality
were investigated. Compositional measurement included
°Brix, pH, titratable acidity, formol values, ascorbic acid
content, total...
In engineering, biology, ecology, medicine, economics and social
science, some processes are essentially bilinear, and some could be
approximated accurately by bilinear processes under certain conditions.
In this thesis the bilinear stochastic process and bilinear time series
are discussed.
Bilinear models essentially are nonlinear; the superposition rule
is not valid....
This study centered upon two objectives. First, to demonstrate and apply a statistical method, the transfer function, and to test its usefulness in regional economic modeling and regional impact ana1ysis; and second, to obtain a better understanding of the causal relationships among total employment, government employment, lumber and wood products...
