Factors affecting establishment, survival, and production of birdsfoot trefoil (Lotus corniculatus L.) and alfalfa (Medicago sativa L.)

Creator:: Cooper, Clee Scott
Abstract:: Field, greenhouse, growth chamber and laboratory experiments evaluated factors affecting establishment, survival and production of birdsfoot trefoil (Lotus corniculatus L.) and alfalfa (Medicago sativa L.) Field studies investigated the effects of a barley companion crop, seedling year harvest management and nitrogen and phosphorus fertilization upon stands, survival and subsequent production...

Surfactant Effects on Adsorption of Recombinant Factor VIII (rFVIII) at the Air-Water Interface

Creator:: Gray, Warren D.
Abstract:: The primary goal was to characterize the adsorption of a recombinant therapeutic protein in the presence of selected surfactant species at the air-water interface. For this purpose, dynamic interfacial tensiometry was used to determine the surface tension kinetics exhibited by protein solutions containing either Tween 80 or the poly[ethylene oxide]-...

Characterization and application of PEO-containing triblock copolymer surfactants

Creator:: Snider, Joshua L.
Abstract:: The action of pendant, polyethylene oxide (PEO) brush layers as nonfouling coatings for biomedical materials is well understood. However progress toward clinical application of stable, high density PEO coatings has historically been impeded by the lack of cost effective, noninvasive methods for their preparation. Triblock polymers featuring a hydrophobic, polypropylene...

Management factors affecting establishment of birdsfoot trefoil (Lotus corniculatus L.)

Creator:: Azocar C., Patricio
Abstract:: A field experiment under irrigation was conducted at the Hyslop Agronomy Farm, near Corvallis, Oregon, during the 1967 growing season to evaluate the effect of barley row spacing, nitrogen rate and placement, and weed competition in the year of seeding upon birdsfoot trefoil (Lotus corniculatus L.) seedling establishment. The effect...

The survival of rhizobia on seeds of Trifolium subterraneum L

Creator:: Radcliffe, John Clive
Abstract:: Field and laboratory tests were carried out to investigate the survival of the root-nodule bacterium, Rhizobium trifolii, when inoculated onto seeds of the pasture legume subterranean clover, (Trifolium subterraneum L.), in order to improve the nodulation and establishment of this plant in acid soils. Field experiments were carried out in...

Influence of supplement composition on utilization of low-quality, cool-season forages by beef cattle

Creator:: McGuire, Dustin L.
Abstract:: Two studies were conducted to evaluate the influence of supplement composition on intake and digestibility of a low-quality (< 6% CP), cool-season forage, as well as cow performance. Treatments included a non-supplemented control (CON), corn (approximately 8% CP), corn and urea (LU = corn + 0.09 mg/kg BW urea, approximately...

The influence of cutting treatments on yield and quality of two alfalfa (Medicago sativa L.) varieties

Creator:: Contreras, David
Abstract:: A field experiment was conducted to study the influence of cutting treatments on the yield and quality of non-irrigated alfalfa in western Oregon. Spring clipping treatments included (1) not clipped, (2) clipped when 6 inches high and (3) clipped when 12 inches high. The hay harvest criteria were (1) near...

Entrapment of Micro-Algae in Modified Alginate Beads for Oxygen and Nutrient Source

Creator:: Hughson, Jason D.
Abstract:: Presented here is an investigation and comparison of two entrapment methods of algae. Conventional calcium alginate bead entrapment is compared to a recently described modified bead entrapment method, utilizing poly(ethylene glycol) and calcium alginate, which results in void or capillary formation within the beads. It is shown that algal growth...

Synthesis of gold nanoparticle surfactants and their self-assembly at oil-water interfaces

Creator:: Truong, Mitchell
Abstract:: Amphiphilic gold nanoparticle surfactants can self-assemble at oil-water interfaces to form stable Pickering emulsions. These nanoparticle surfactants have previously been synthesized by functionalizing gold nanoparticles with thiol terminated polyethylene glycol (PEG-thiol), and subsequently with an alkane-thiol. It is necessary to improve the bio-compatibility of the nanoparticles if they are to...

The influence of seeding rate on plant population, yield and quality of two alfalfa (Medicago Sativa L.) varieties

Creator:: Al-Hassani, Madhat M.
Abstract:: A field study was conducted in the Willamette Valley near Corvallis, Oregon, to determine the influence of seedling rate, drill row spacing, grass association, and variety on the yield of dry matter and quality (crude protein content and leafiness) of alfalfa. Treatments included seeding rates of 7.5, 10, 15 and...
