Growth and development of spring grain species as affected by planting date

Creator:: Armah-Agyeman, Grace
Abstract:: Changes in the federal farm program, in rainfall pattern and quantity, and increased incidence of herbicide resistant weeds and diseases have generated increased interest in spring grains in the Pacific Northwest. However, spring grains have traditionally been treated as minor crops in this region, thus little research has been done...

Population dynamics, extraction, and response to nematicide of three plant parasitic nematodes on peppermint (mentha piperita L.)

Creator:: Merrifield, Kathryn J.
Abstract:: The efficiencies of wet sieving/sucrose centrifugation (WS/SC) recovery of Pratylenchus penetrans (59 %), Paratylenchus sp., (80 %), and Criconemella xenoplax (66 %) were established. Baermann funnels (BF) recovered significantly more P. penetrans (p = 0.01) and significantly less (p = 0.01) C. xenoplax than did WS/SC. While densities of P....

An attitudinal assessment of proposed services for the Oregon State University Federal Credit Union

Creator:: Russell, Amber Simmons
Abstract:: Oregon State Federal Credit Union (OSU FCU) members' attitudes toward proposed services, and the association between the importance rating of a "common bond" (loyalty) and use of selected services of the OSU FCU were examined. The study utilized data from the member survey commissioned in 1982 by the OSU FCU...

Multiple excitation fluorometer for in situ oceanographic applications

Creator:: Desiderio, Russell A., Moore, Casey, Lantz, Carl, and Cowles, Timothy J.
Abstract:: A new in situ fluorometer for the detection of oceanic photosynthetic pigment fluorescence is described. Emission spectra from 546 to 733 nm are recorded for each of three different visible excitation bands ten times a second. A Spectralon cell is used to improve the excitation coupling to and the collection...

In situ monitoring of ocean chlorophyll via laser-induced fluorescence backscattering through an optical fiber

Creator:: Cowles, Timothy J., Moum, James N., Desiderio, Russell A., and Angel, Stanley M.
Abstract:: The first seagoing test of a prototype laser/fiber-optic system for in situ detection of ocean chlorophyll fluorescence is described. Radiation at 488 nm originating from a shipboard argon laser was transmitted through 20 of 200-µm core optical fiber to the distal tip mounted on the microstructure profiler, the Rapid Sampling...

Using lasers to probe the transient light absorption by proteorhodopsin in marine bacterioplankton

Creator:: Desiderio, Russell A., Laney, Samuel R., Letelier, Ricardo M., and Giovannoni, Stephen J.
Abstract:: We constructed an experimental apparatus that used lasers to provide the probe beams for measuring the transient absorption kinetics of bacterioplankton that contain proteorhodopsin, a microbial protein that binds retinal and is analogous to animal rhodopsin. With this approach we were able to observe photocycles characteristic of functioning retinylidene ion...

Microstructure Profiles of Laser-induced Chlorophyll Fluorescence Spectra: Evaluation of Backscatter and Forward-Scatter Fiber-Optic Sensors

Creator:: Desiderio, Russell A., Cowles, Timothy J., Moum, James N., and Myrick, Michael
Abstract:: The implementation and characterization of backscatter and forward-scatter fiber-optic fluorescence sensors attached to a microstructure profiling instrument are described. By using an optical multichannel array detector to record emission spectra, eight profiles per hour of chlorophyll fluorescence spectra at 2-cm intervals can be obtained throughout the upper 100 m of...

Replica-plating and computer analysis for rapid identification of microorganisms in seafoods

Creator:: Corlett, Donald A.
Abstract:: A method was devised and tested for rapid and quantitative identification of microbial flora in fresh seafoods. The rapid identification of large numbers of isolates was made possible by (1) a simplified identification scheme established by reference culture studies and from the known reactions of microorganisms reported in the literature,...
