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)...

According to the World Health Organization, there are an estimated 1.4 million blind children in
the world, of whom approximately 300,000 live in Africa. About one-half of these cases of
childhood blindness could have been prevented. Each year, an estimated half a million children
become blind (nearly one per minute),...
A survey of a non-random sample of adults was conducted in Angers, France to
investigate possible cultural changes in dietary behaviors that may contribute to
increasing rates of obesity. Participants described contemporary habits regarding eating
habits and activity level, as well as attitudes and opinions about obesity. The results
largely...
The thesis presented here is a quantitative study of vacant
urban land in Corvallis, Oregon. In order to present this study the
writer first studied the available literature and found that little had
been published dealing with causal factors of vacant urban land.
Rather, it was found that several writers...
The physical characteristics and spatial location of
land are hypothesized to be significant inputs to its
valuation. This research evaluates the influence of
locational, economic, and physical site variables on the
assessed value of real property.
Evaluation of such influences is based on a stratified
systematic sample of land parcels...
The navigability of the Columbia river permits Portland, located more than 100 miles inland from the Pacific Ocean, to function as the major port of the state of Oregon. It could be expected that the waterfront spanning the greatest share of the distance between Portland and the ocean should reflect...
To quantify the relative activity contributions of beta emitters in mixed emission source spectra, the triple-layer phoswich detector was modeled to generate beta energy absorption spectra from mixed beta sources. These mixed sources include four pure beta emitters (C-14, Tc-99, Sr-90, and Y-90). Monte Carlo N-Particle (MCNP) computer code was...
