Taxonomy and distribution of the leaf-hopper genus Aphrodes Curtis (Homoptera:Cicadellidae) in North America

Creator:: Klein, Terry Allen
Abstract:: The subfamily Aphrodinae is represented in the Nearctic Region by eight species contained in a single tribe, Aphrodini, and genus Aphrodes. The external and internal morphology, biology and ecology of the Nearctic members of the genus Aphrodes were investigated. Distributional evidence indicates that six of the eight species, belonging to...

Analysis of fourteen trace elements in Saudi Arabian layered gabbros by radiochemical neutron activation analysis

Creator:: Palmer, Curtis Allyn
Abstract:: Eight layered gabbro samples from two layered complexes, two xenoliths, one basalt from a hot brine area and a standard basalt rock (BCR-1) were analyzed by RNAA (radiochemical neutron activation analysis) for 14 trace elements, Au, Ni, Co, Ag, Sb, Se, Zn, In, T1, Rb, Cs, U, Ba and Sr....

Genetic factors that provide adult plant resistance against Puccinia striiformis f. sp. tritici to wheat cultivar 'Stephens' in a multilocation analysis.

Creator:: Vazquez, Maria Dolores
Abstract:: Stripe rust (Puccinia striiformis f. sp. tritici) has been receiving increased attention in the USA since the appearance of more virulent races detected in the past decade. These races caused yield losses even in areas where the disease previously was rarely detected. Host plant resistance is the most cost effective...

Evaluating the Effects of a Parasitic Copepod (Salmincola californiensis) on the Performance of Juvenile Chinook Salmon (Oncorhynchus tshawytscha)

Creator:: Neal, William T.
Abstract:: Pacific salmon (Oncorhynchus spp.) rearing in lakes and reservoirs have been known to become heavily infected with an ectoparasitic copepod (Salmincola californiensis). Little is known about the factors that affect the parasite infection prevalence and intensity. However, previous research suggests that the parasite may negatively affect the fitness and survival...

Quantitative trait loci mapping of yield, its related traits, and spike morphology factors in winter wheat (Triticum aestivum L.)

Creator:: Gaynor, Robert C.
Abstract:: Increasing grain yield in wheat (Triticum aestivum L.) is a challenging task, because yield is a complex trait controlled by many genes and highly influenced by environmental factors. The genetic control of yield components and other traits associated with yield may be less complex and thus more manageable for breeding....

The computer, the computer user group, and the civil engineer

Creator:: Cunningham, Gerald Robert
Abstract:: An attempt to determine the relationship between the computer, the computer program exchange organization and today's practicing civil engineer has just been completed. A questionnaire was used to obtain information and opinions from 850 selected practicing civil engineers. Based on those questionnaires reaching their addresses, a return rate of 81.7...

Design considerations for a miniature atmospheric engine with a magnet-actuated autonomously-reciprocating in-cylinder regenerator for portable power production

Creator:: Yarger, David J.
Abstract:: Driven by the need for high energy-density power sources, demand has stimulated the development of small-scale engines. A small-scale engine with a fuel supply could replace batteries and utilize higher energy-density liquid hydrocarbon fuels; such an advance could deliver a new age of portable devices. Currently, operable small-scale engines exist;...

An Evaluation of the Effects of the Parasite Salmincola californiensis on At-Risk Chinook Salmon Populations

Creator:: Gardner, Ethan N.
Abstract:: Once abundant in their native range, Pacific salmon species (Oncorhynchus spp.) were widely distributed across the northern Pacific Rim from South Korea and Japan to the Sacramento River in California. Remaining populations are subject to population-level threats, including pathogens. The freshwater parasitic copepod Salmincola californiensis is associated with the reduced...

Influence of cover crop residue management on soil moisture, vine growth, and productivity in a pre-production vineyard in the Willamette Valley

Creator:: Curtis, Morgan A.
Abstract:: The use of cover crops in young vineyards is not widely accepted in the Pacific Northwest due to concerns of water and nutrient competition between the cover crop and vines. The last 2 years of a 4-year study started in 2009 are reported here. The study evaluated the use of...

An analytical model for predicting truck performance on interstate highways

Creator:: Cantwell, William Curtis
Abstract:: This thesis describes a Truck Performance Simulation Model developed for use in a United States Department of Transportation university research project entitled "The Energy, Economic and Environmental Consequences of Increased Vehicle Size and Weight." The performance of the truck is found by specifying its engine, driveline and tire characteristics and...
