The influence of light, temperature and humidity on the herbicidal activity of bromoxynil (3,5-dibromo-4-hydroxybenzo-nitrile) on Amsinckia intermedia

Creator:: Zimmerman, Martin (Martin Joseph)
Abstract:: The use of bromoxynil (3,5-dibromo-4-hydroxybenzonitrile) to control broadleaf weeds in cereal crops has become widespread. This herbicide has not always performed satisfactorily for reasons which were not clearly evident. The effects of temperature, light and humidity on the herbicidal activity of bromoxynil on coast fiddleneck, Amsinckia intermedia, were studied. Fiddleneck...

Kinetic studies of the oxygen requirement of some amine oxidases

Creator:: Swindell, Robert Malcolm
Abstract:: Some kinetics of the oxygen requirement of amine oxidases have been investigated using bovine plasma monoamine oxidase (PAO) and pea seedling diamine oxidase (DAO). A system is described for studying enzyme reactions under controlled oxygen tension and in an O₂-free N₂ atmosphere. O₂ Km values were determined at two different...

Highlights in the changing resource perception and land use of the Willamette River flood plain, Albany-Corvallis area

Creator:: Lewis, Anthony J.
Abstract:: Taking advantage of a favorable physical system but also risking the hazards of flooding, man has long occupied flood plain land. He has attempted to adjust rivers to his needs in order to reduce flood loss, but the rising cost of flood protection accompanied by an increase in flood damage...

Some cytological aspects of streak mottle virus in Lilium speciosum Thunberg

Creator:: Elser, John Elmore
Abstract:: Cultivated lilies include many garden varieties in addition to the Easter lily, Lilium longiflorum Thunb. A popular member of the garden group is Lilium speciosum Thunb., whose leaves can be discolored by a virus symptom described as streak mottle. This disorder is characterized by dashes of chlorotic tissue interspersed with...

The effect of boundary geometry on internal density currents in a density stratified reservoir

Creator:: Spurkland, Torbjorn
Abstract:: The effects of boundary geometry on internal density currents in a density stratified reservoir were investigated in a laboratory model. When water was simultaneously withdrawn and admitted to the reservoir, a complex current regime was established. The general flow pattern is described, and the influence of physical variables on the...

The effect of entrance configuration on local heat transfer coefficients in subsonic diffusers

Creator:: Stoffel, Edward Oswald
Abstract:: The effects of round, square, and reentrant entrances on flow regimes and local heat transfer coefficients were determined using a symmetrical, plane-wall two-dimensional, subsonic air diffuser with one of the diverging walls heated and maintained isothermal. Flow and heat transfer studies were made at total divergence angles ranging from 0...

Dynamic measurement of Timoshenko beam shear coefficient

Creator:: Nelson, Daniel Loren
Abstract:: The Timoshenko beam theory, as an engineering alternative to the elementary and exact theories, introduces a factor, k', called the shear coefficient which has been given various interpretations and values. It is the objective of this study to experimentally evaluate k' for a brass bar of rectangular cross-section. Analytical results...

The present status of plastics as an engineering material

Creator:: Summersett, John Steve
Abstract:: The present status of plastics is one of constant change, but this thesis attempts to focus attention on the state of the industry as of 1967. Beginning with a brief title definition and history of plastics, the writer proceeds to a discussion on the structural characteristics of plastics. Under this...

A study of the deterioration of X-ray fluoroscopic screens

Creator:: Properzio, William Stuart, 1940-
Abstract:: From the time when fluoroscopic screens were first used there have been scattered references to reduction in their light output due to age, use, etc. References are scarce and usually devoid of quantitative data. A long-range program has been set up in an effort to arrive at some meaningful information....

Selected variables influencing vacant urban land in Corvallis, Oregon

Creator:: Meade, James Montgomery
Abstract:: 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...
