Economic and environmental evaluation of alternative farming systems for row crop and dairy farms in Northern Malheur County

Creator:: Vermilyea, Kathy Jo
Abstract:: Malheur County is located in the southeast corner of Oregon and consists of about 64 million acres of which 260,000 acres is irrigated. Groundwater contamination has been found in a 115,000 acre area in Northeastern Malheur County. The main source of the groundwater contamination is agricultural practices. The overall objective...

Using advanced spreadsheet features for agricultural GIS applications

Creator:: Halbleib, Michael D.
Abstract:: A GIS analysis procedure was developed to explore relationships between imagery, yield data, soil information, and other assessments of a field or orchard. A set of conversion utilities, a spreadsheet, and an inexpensive shape file viewer were used to manipulate, plot, and display data. Specific features described include procedures used...

Implementing best management practices in small commercial and non-commercial animal enterprises

Creator:: Godwin, Derek C.
Abstract:: Small commercial and non-commercial animal enterprises (SCAEs) raise a few beef cows, horses, pigs, sheep, poultry, and other animals on a few acres. These enterprises are often located in suburban areas of watersheds and show potential for degrading water quality through to increased bacterial, nitrogen, and phosphorus concentrations. SCAEs implement...

Land use and nonpoint source phosphorus pollution in the Dairy-McKay hydrologic unit area of the Tualatin River Basin, Oregon

Creator:: Wolf, Donald W.
Abstract:: Human activities may contribute to the eutrophication of surface waters by providing nutrients to aquatic ecosystems. Phosphorus is frequently identified as a nutrient that is limiting to most aquatic ecosystems under natural conditions. Sources of phosphorus contributing to eutrophic conditions often include nonpoint sources that are dispersed across the landscape....

Seismic performance of reinforced concrete bridge columns constructed with grade 80 reinforcement

Creator:: Link, Tim B.
Abstract:: The research presented in this thesis assessed the use of high strength steel (HSS) reinforcement for use in reinforced concrete (RC) bridge columns. HSS is not currently allowed in reinforced concrete bridge columns due to a lack of information on the material characteristics and performance information when used in RC...

Low power, high performance pseudo-static D flip-flop

Creator:: Low, Tim D.
Abstract:: Digital systems, in particular microprocessor, have recently experienced phenomena growth in performance. Both technology advancement and clever design have sustained this performance growth. As clock frequency heads into the Ghz range, new circuit design, for both logic and storage, are needed. Such new circuit technology must provide needed performance with...

Effect of an Idealized Mangrove Forest of Moderate Cross-shore Width on Loads Measured on a Sheltered Structure and Comparison with Predicted Forces

Creator:: Mitchell, William T.
Abstract:: As coastal communities face increasing chronic and acute hazards, nature-based coastal engineering solutions have experienced a rapid growth in popularity and interest. Recent works on this topic have shown that “Green Infrastructure” may be effective at mitigating coastal hazards and therefore provide sustainable adaptation alternatives to traditional engineering solutions such...
