The effects of selected commercial detergents used at various temperatures on wool : soil removal as evaluated by radioactive tracer methods and dimensional changes

Creator:: Hodam, Barbara Lenore
Abstract:: One purpose of this study was to evaluate three commercial detergents by comparing their removals at 70 and 120°F. of palmitic acid and clay components of a simulated natural soil which had been applied to wool yarns by immersion and abrasion methods. These detergents were a built soap and two...

Glyphosate Resistance and Tolerance in Italian Ryegrass (Lolium perenne spp multiflorum) : Termination Treatments, Cultivar, and Resistance Evaluation

Creator:: MacPherran, Robert Chase
Abstract:: Annual ryegrass, or Italian ryegrass (Lolium perenne spp. multiflorum), has been the most stable, in terms of acres, grass produced for the past 25 years in Oregon. Increased interest in Italian ryegrass as a cover crop has increased demand for quality seed. Ideal Italian ryegrass cover crop cultivars are named...

Preparation and comparative solubility of poly-L-tyrosyl lysozyme and poly-O-methyl-L-tyrosyl lysozyme

Creator:: Venier, Lynn Corrine
Abstract:: In order to examine some possible tyrosyl interactions, poly-tyrosyl lysozyme and poly-O-methyltyrosyl lysozyme were prepared and their solubilities were compared. Both derivatives exhibited similar pH dependent solubilities, showing a minimum solubility at about pH 8. Their solubilities varied with temperature, having a positive enthalpy of solution. The effect of a...

Scientists' perspectives on the importance of scientific communication in natural resource decision-making

Creator:: Shaw, Christine Michelle
Abstract:: Natural resource decisions require consideration at many levels, ranging from how one invertebrate will be affected by a nearby road, to how an entire watershed will be transformed by a massive clearcut. Considerations reach farther than just the local ecological community-human communities, economies, and future impacts on the communities and...

Mitigating cyanobacterial harmful algae blooms : the role of plant humics

Creator:: Theis, Susan A. F.
Abstract:: Cyanobacterial harmful algae blooms (cyanoHABs) are a growing concern worldwide due to damage of ecosystems and threats to human health. Previous research indicates that plant humics from aquatic and wetland vascular plants are effective inhibitors of cyanobacterial metabolism and growth and may be useful as control agents for mitigating cyanoHABs....

Poly(vinyl alcohol) / cellulose nanocomposite barrier films

Creator:: Paralikar, Shweta
Abstract:: There is a continual interest in developing robust, flexible, durable, lightweight, waterborne polymer barrier coatings which are increasingly resistant towards both chemical warfare agents as well as an ever growing number of toxic industrial chemicals. In this study, barrier films were prepared with poly(vinyl alcohol) (PVOH) and varying amounts of...

Geographic factors as retardants to the development of Alaska's mineral industries

Creator:: Francis, Karl Earvil
Abstract:: The various elements of physical geography are commonly entertained as factors retarding the mineral industries of Alaska. It has been shown by numerous writers that the mineral industries of Alaska are, indeed, in a difficult situation. Only the petroleum industry and sand and gravel for construction are of much significance...

Some factors affecting absorption and translocation of phenoxyalkylcarboxylic acids in plants

Creator:: Norris, Logan A. (Logan Allen)
Abstract:: Studies were conducted to determine the influence of formulation and molecular configuration of some chlorinated-phenoxyalkylcarboxylic acid herbicides on their absorption, translocation and metabolism in bigleaf maple, Acer macrophyllum, Pursh. Five to eight year old bigleaf maple seedlings were treated with one percent solutions of carbon 14-labeled herbicids. After three days...

Tracer experiments in a non-uniform porous medium : implications of diffusive mass transfer on the late-time breakthrough behavior

Creator:: Freiherr von Schwerin, Claudius
Abstract:: Mass transfer processes were evaluated in an artificial, non-uniform porous medium with a power law distribution of diffusion rate coefficients obtained from physical characterization of solute and porous medium. Breakthrough curves of several pulse experiments conducted at different velocities were compared (1) to analytical expressions for concentrations at mass transfer...
