Serologic survey of infectious disease agents in black bears (Ursus americanus) of California, Oregon, and Washington

Creator:: Mortenson, Jack A.
Abstract:: The causes of natural mortality and disease in free ranging black bears, Ursus americanus, in California, Oregon, and Washington are poorly known. Life history components, such as scavenging and overlapping habitat with many species of carnivores, potentially expose bears to a wide range of infectious disease agents. To date, no...

Landscape composition around northern spotted owl nests, central Cascade Mountains, Oregon

Creator:: Swindle, Keith A.
Abstract:: This study describes the composition of forest landscapes surrounding northern spotted owl (Strix occidentalis caurina) nests in the central Cascade Mountains of Oregon. I compared forest composition around 126 owl nests in 70 pair territories with forest composition around 119 points drawn randomly from all terrestrial cover-types, and around 104...

Constructed wetland treatment of fecal coliform in dairy pasture runoff

Creator:: Osborn, Erik C. J.
Abstract:: A constructed wetland receiving pasture runoff from a dairy in Tillamook, OR was monitored during the winter of 1997-98 in order to estimate coliform treatment efficiency during winter high flow periods. Monitoring occurred during four sampling periods, each lasting 2 to 4 days. Samples were taken every two hours from...

Effect of crop level on yield components, fruit and wine composition, and wood carbohydrate reserves of Pinot noir grapes

Creator:: Brasher, Erik W.
Abstract:: Crop thinning trials were studied during two seasons at two locations in the northern Willamette Valley of Oregon. At Willakenzie Estate (site #1), research vines were Pinot noir clone Dijon 113 on 3309 rootstocks trained to a double Guyot. Vines were established in 1996 at a spacing of 2.5 x...

Development of organocatalyzed, intramolecular heteroatom Michael addition and application towards alkaloid synthesis

Creator:: Carlson, Erik
Abstract:: Effective methods for the enantiopure formation of substituted piperidine rings are significantly important due to their presence in alkaloid products. A valuable method to form these ring systems would be via an intramolecular heteroatom Michael addition from the corresponding enone or enal. Described herein is a methodolgy that has been...

Cleaning and Sanitizing Surfaces on Produce Farms: Optimizing What, How, and When

Creator:: Ohman, Erik
Abstract:: Production of fresh produce takes place outdoors, and therefore, is exposed to many routes of contamination (e.g., soil, contaminated water, manure, etc.) by human pathogens. Although precautions are taken to reduce this risk, pathogens can be regularly introduced to produce handling facilities. To manage the risk of cross-contamination from potentially...

Electrochemical modeling of cathodic protection systems applied to reinforced concrete structures

Creator:: Muehlenkamp, Erik B.
Abstract:: A numerical model for the cathodic protection of steel in reinforced concrete is developed. Parameters are set to represent a three-dimensional section of a bridge beam exposed to the atmosphere and coated with a thermally sprayed zinc anode. Both diffusion of oxygen and conduction of charge within the concrete are...

Integrated dual cycle energy recovery using thermoelectric conversion and an organic Rankine bottoming cycle

Creator:: Miller, Erik W.
Abstract:: Hot engine exhaust and industrial process exhaust represents a resource that is often rejected to the environment without further utilization. This resource is prevalent in the transportation and industrial process sectors, but stationary engine-generator systems also typically do not utilize this resource. Engine exhaust is considered high grade heat and...

Characterization of a digital phase locked loop and a stochastic time to digital converter

Creator:: Geissenhainer, Erik D.
Abstract:: A digital phase locked loop (DPLL) and a statistical time-to-digital converter (STDC) were previously fabricated in a 0.35Âµm, 3.3V SOI CMOS process. This work summarizes these designs and characterizes the measured performance. Simulations supplement the measurements where applicable. The DPLL was found to reach a locked state under a limited...
