Free-radical hydrogen abstraction from polycyclic aliphatic hydrocarbons

Creator:: Koch, Victor Raymond
Abstract:: Six polycyclic aliphatic hydrocarbons were reacted with the trichloromethyl radical photolytically generated from bromotrichloromethane at 40°. Relative rates of reaction were correlated with a computer analysis of the change in strain energy in going from the ground state to the intermediate. A good correlation between the log of the relative...

Characterization studies and industrial control development for the brushless doubly-fed machine

Creator:: Koch, Brian
Abstract:: This thesis presents the development of a supervisory controller for a pre-commercial Brushless Doubly-Fed Machine (BDFM) drive system. In addition, characterizations of new diecast rotors for the BDFM are presented. Using the characterization results from the new rotors, a control scheme was developed to allow a BDFM to be packaged...

Reconnecting aquatic habitats : validating historical habitat use by anadromous fishes using telemetry and stable isotope analysis above barriers

Creator:: Lewis, Sierra Koch
Abstract:: I conducted a study to identify potential spawning habitat for anadromous salmonids above a 60-year-old hydropower dam in the headwaters of the North Umpqua River in Oregon. Like many other historical salmonid-bearing rivers, little documentation exists for anadromous fish presence above potential natural obstacles upstream of Soda Springs Dam. My...

Utilizing emergent web-based software tools as an effective method for increasing collaboration and knowledge sharing in collocated student design teams

Creator:: Koch, Michael D.
Abstract:: Over the last few decades, the methods and tools through which humans collaborate, share knowledge and generally communicate have been advancing at a rapid pace. Thanks mostly to advances in broadband internet, cheap data storage and fast microprocessors, humans now have the ability to work together in ways that even...

Varietal resisitance of hops, Humulus lupulus (Linn.), to the two-spotted spider mite, Tetranychus urticae (Koch)

Creator:: Mayberry, Terrel Wilson
Abstract:: The purpose of this study was to determine the relative resistance of genetic lines of hops, Humulus lupulus (Linn.) to the two-spotted spider mite, Tetranychus urticae (Koch) in western Oregon. Approximately three-hundred genetic lines of hops were screened under insectory conditions during the 1965 growing season at Corvallis, Oregon. Reduction...

Mechanisms of hop resistance to the twospotted spider mite (Tetranychus urticae Koch)

Creator:: Peters, Kay Myra
Abstract:: Hop varieties were compared under field and greenhouse conditions to determine their relative susceptibility to the twospotted spider mite, Tetranychus urticac Koch. A fertility schedule was prepared for mites on resistant and susceptible varieties, and tests were conducted to compare sex ratio, oviposition rate, survival rate, and developmental rate of...

Effects of early season immigration on acaricide resistance of Tetranychus urticae Koch on strawberry in the California Pajaro and Salinas valleys

Creator:: Miller, Richard W. (Richard William), 1958-
Abstract:: In the Pajaro Valley near Watsonville, California, twospotted spider mite (Tetranychus urticae Koch) populations were surveyed in 1983 and '84 to detect the influence of immigrants from nursery plants or surrounding vegetation on subsequent resistance development to cyhexatin and formetanate in strawberry fields. Susceptible mites (cyhexatin LC50 = 0.0039 %...

Vegetation and Small Mammal Responses to Western Juniper (Juniperus occidentalis) Control in Eastern Oregon

Creator:: Morozumi, Corinne N.
Abstract:: Shrub-steppe ecosystems of western North America provide habitat for many wildlife species, are important components of public and private rangelands, and offer recreational opportunities for millions of people. They are some of the most vulnerable ecosystems in the United States and have been altered by human activities such as livestock...
