A motor-generator and supercapacitor based system for microgrid frequency stabilization

Creator:: Crispo, Richard F.
Abstract:: This research introduces an energy storage system to deliver microgrid frequency response. A doubly-fed induction generator (DFIG) and a squirrel cage induction machine (SCIM) are coupled together as a motor/generator set to deliver an immediate inertial response to a change of frequency, and an inverter and supercapacitors deliver short term...

Exploration of Simultaneous Anammox and Denitrification (SAD) Biofilm Processes for Nitrogen Removal

Creator:: Hilliard, Richard F.
Abstract:: Anammox (anaerobic ammonium oxidation) bacteria are capable of providing low-cost nitrogen removal for numerous types of wastewaters. However, low growth rates cause long startup-times and inhibition by oxygen and metabolic substrates necessitate close process control to maintain performance. Incorporation of Simultaneous Anammox and Denitrification (SAD) into constructed wetlands could provide...

Spring, summer and fall use by cattle and big game on foothill rangelands

Creator:: Miller, Richard F.
Abstract:: The objectives of this study were to evaluate environmental factors influencing use of several plant communities by cattle, elk and deer; determine under story production by plant species and the amount utilized by cattle, elk and deer in certain plant communities; evaluate the interactions of range use between cattle, elk...

An investigation of the effects of nutritional status on the action of insulin in rainbow trout (Salmo gairdneri)

Creator:: Ablett, Richard F.
Abstract:: Three studies were conducted to evaluate the relationship between insulin and nutritional parameters in rainbow trout. In the first study effects on growth parameters and tissue composition of rainbow trout were investigated following injection of bovine insulin at two dose levels every 48 hr for 56 days. In addition, [¹⁴C]-leucine...

Geology of the Bagby Hot Springs area, Clackamas and Marion Counties, Oregon

Creator:: Dyhrman, Richard F.
Abstract:: The thesis area is located southwest of Portland, Oregon, in the Western Cascades. In the area are volcaniclastic rocks and lava flows that range in composition from basaltic andesite to dacite. The dominant volcaniclastic rock type is thin intracanyon ash-flow tuff. The dominant lava flows are a thick sequence of...

Attenuation of rainfall intensity by forest canopies

Creator:: Keim, Richard F.
Abstract:: Interception of precipitation by forest canopies has been found previously to reduce rainfall intensity, but this effect is poorly understood. The goal of this research is to quantify the attenuation of rainfall intensity by forest canopy interception, with the specific objective of estimating the contribution of this attenuation to hillslope...

Coping With an Increasing Import Base: A Case Study of the Southeast U.S. Shrimp Processing Industry

Creator:: Keithly, Walter, Diop, Hamady, and Kazmierczak, Richard F.
Abstract:: It is well known that world production of shrimp, particularly farm-raised product, has increased significantly since the early-to-mid 1980's and that much of the product is directed to the U.S. market. Less well known is the fact that the product composition of the U.S. imported product (e.g., headless shell-on, peeled)...

Medusahead (Taeniatherum asperum Nevski) : a review and annotated bibliography

Creator:: Hilken, Thomas O. and Miller, Richard F.
Abstract:: Medusahead (Taeniatherum asperum Nevski), a winter annual native to the Mediterranean region of Eurasia, has infested several million acres of rangeland in the northwestern United States. It has been estimated carrying capacity for domestic livestock on infested ranges has been reduced 75 percent. The review is a condensed summarization of...

On the origins of the variability of the Malvinas Current in a global, eddy - permitting numerical simulations

Creator:: Fetter, Antonio F. and Mantano, Richard P.
Abstract:: This article investigates the origins of the variability of the Malvinas Current (MC) transport using the results of an eddy-permitting ocean general circulation model. First, the dynamical links between the variabilities of the MC and the Antarctic Circumpolar Current (ACC) transports at the Drake Passage are established. Time series analyses...
