Development of oven and Karl Fischer techniques for moisture testing of grass seeds

Creator:: Benjamin, Ethan
Abstract:: Seed moisture is a primary factor influencing seed quality during harvesting, storage, and marketing of grass seed. However, the Association of Official Seed Analysts' Rules for Testing Seeds do not contain methods for moisture testing. The oven methods in use by seed testing laboratories in the U.S. are diverse and...

Structure, abundance, and distribution of pelagic zooplankton in a deep, oligotrophic Caldera Lake

Creator:: Karnaugh, Elena N.
Abstract:: From July 1985 to April 1987 the pelagic zooplankton community of Crater Lake, Oregon was studied to determine taxonomic structure, absolute and relative densities, and spatial and temporal distributional patterns. Samples were collected using vertically-towed zooplankton nets. The community structure consisted of two cladoceran and nine rotifer species, which were...

Trinexapac-ethyl and open-field burning in creeping red fescue (Festuca rubra L.) seed production in the Willamette Valley

Creator:: Zapiola, Maria Luz
Abstract:: Open-field burning has been an effective, economical, and widespread method of post-harvest residue management in creeping red fescue seed production in the Willamette Valley since the late 1940s. However, the use of field burning has been legislatively restricted due to air quality and safety issues. The foliar-applied plant growth regulator...

Possible association between dwarfing genes Rht₁ and Rht₂ and the reaction to Septoria tritici blotch in winter wheat (Triticum aestivum L. em Thell)

Creator:: Baltazar, Baltazar
Abstract:: Four isogenic lines possessing different combinations of height reducing genes Rht₁ and Rht₂ from 'Norin 10' were crossed to a short stature, early maturing, septoria susceptible cultivar identified as the 'Tibet Dwarf'. The isogenic lines originated from the backcross population of 'Itana'/3/'Norin 10'/'Brevor 14'//6*'Itana'. Parents, F₁ and F₂ generations provided...

β-lactoglubin adsorption equilibrium and kinetics at silanized silica surfaces

Creator:: Krisdhasima, Viwat
Abstract:: The adsorption equilibrium and kinetic behavior exhibited by β-lactoglobulin at silanized silicon surfaces of varying hydrophobicity were examined using ellipsometry. Adsorption equilibrium results were used to construct adsorption isotherms; the adsorbed mass of β-lactoglobulin was observed to increase with increasing surface hydrophobicity, within a defined range of hydrophobicity. Adsorption kinetics...

Pharmacokinetic modeling and simulations of gastrointestinal transit effects on drug pharmacokinetics from enteric-coated pellet formulations and their applications

Creator:: Watanalumlerd, Prapoch
Abstract:: Effects of gastrointestinal transit on plasma concentrations of drugs from enteric-coated pellet formulations were demonstrated using pharmacokinetic models describing plasma concentrations of drugs from various enteric-coated pellet formulations. Gastric emptying time, lag time of emptying, and drug release rate from pellets in the small intestine, along with other pharmacokinetic parameters...

New configurations of bandpass filters in single and multilayer environment

Creator:: Gururajan, Kala
Abstract:: Mobile and telecommunication industry has experienced tremendous growth in the recent past. Miniaturization and increased functionality have become necessary for all passive components in the system. Bandpass filters are critical passive components in any communication system and the existing designs in the crucial 1-10 GHz bandwidth suffer many drawbacks. For...

Variation in adaptive traits of coastal Douglas-fir : genetic and environmental components

Creator:: Balduman, Lisa M.
Abstract:: Cold hardiness and phenology are important adaptive traits for perennial plant species in temperate climates. Timing of growth, dormancy, and associated cold acclimation and deacclimation represents a delicate balance between maximizing growth under favorable conditions and minimizing frost damage under unfavorable conditions. Geographic patterns of genetic variation in adaptive traits,...
