One approach to the development of a simple Geographic Information System for management of natural resource areas

Creator:: Gaston, Greg G.
Abstract:: This project explored one set of tools and procedures that appeared to have the potential to make the handling of the spatial data necessary for resource management more efficient and effective. This project used data from the Nature Conservancy's Lawrence Memorial Grassland Preserve and was designed to explore a low...

Importance of timber-related revenues to local governments in Oregon and the effects of forests in Oregon on property tax rates

Creator:: Hackworth, Kevin
Abstract:: Local governments in Oregon receive money from the forestry sector in a number of ways. This paper briefly describes public and private forestry sector sources and the relative importance of their payments to five forms of local governments by county for fiscal year 1982-83 to 1985-86. An analysis of the...

Federal forest revenue-sharing in coastal Oregon : an assessment of historical and future tax equivalence

Creator:: Powell, Leslie A. (Leslie Ann)
Abstract:: Public land ownership withdraws property from the tax base of local property tax districts. Publicly-managed lands occupy approximately 17.5 million acres of forested lands in Oregon (inclusive of federal, state, and county ownership). To compensate local taxing districts for foregone property tax collections, Congress enacted a series of federal revenue-sharing...

The Development of a Hybrid Particle-in-Cell Simulation Code in C++ for the Modeling of the SPT-70 Hall Thruster

Creator:: Myers, Conner J.
Abstract:: In order to support the growing satellite propulsion industry, a hybrid Particle-In-Cell (PIC) simulation with fluid treatment of electrons and neutral particles was developed to model the SPT-70 Hall thruster. The 2D, C++ code assumes azimuthal symmetry and a uniform magnetic field in the radial direction with the simulation domain...

Jerking behavior among phytoseiid mite species (Acari: Phytoseiidae)

Creator:: Blackwood, J. Scott
Abstract:: Jerking, which we defined as a pronounced and often repeated lunging of the entire body, was studied in larvae among seven species of phytoseiid mites, and in the nymphal stages of Neoseiulus fallacis (Garman). This behavior was observed in all active immature stages of N. fallacis, and in larvae of...

Functional imaging reveals modest strain concentrations associated with implant micromotion using modified BAK interbody cages

Creator:: Berry, Daniel J.
Abstract:: Interbody fusion cages are increasingly used in the treatment of spinal disease and injury in order to stabilize movement and promote arthrodesis of the vertebral bodies, but the micro-mechanics of the interaction between the cage and the adjacent host bone is not fully understood. This information has bearing on post-surgical...

Removal of E. coli with alternative media Biosand filters

Creator:: Fulton, Nathan J.
Abstract:: When Biosand filters cannot be constructed with crushed quarry rock due to resource limitations, a suitable alternative filter media is needed. In this research, two crushed quarry rock alternatives were examined. Three bench-scale Biosand filters with crushed rock, beach sand, and heat-treated beach sand media were simultaneously dosed with Willamette...

A microchannel-based thermal management system for hydrogen storage adsorbent beds

Creator:: Steigleder, Leif J.
Abstract:: Hydrogen has been shown to be a promising replacement for fossil fuels for use in light duty vehicles because it is a clean, renewable and plentiful resource with a high gravimetric energy density. However, in order to obtain an acceptable volumetric energy density, densification of the hydrogen is required. Adsorptive...

U(VI) transport in subsurface materials: is two-site, one-species modeling sufficient?

Creator:: Harrington, Stephanie J.
Abstract:: Uranium adsorption to Hanford sediment was studied for various pH, total inorganic carbon concentrations, and total U(VI) concentrations. Both batch and transport studies were done in an attempt to understand the adsorptive trend of U(VI) on Hanford sediment, and the changes in adsorption as both pH and total inorganic carbon...

Scaling study of the depressurized conduction cooldown event in the high temperature test facility using RELAP5-3D/ATHENA

Creator:: Aldridge, Robert J.
Abstract:: In 2008, the Department of Energy (DOE) and Nuclear Regulatory Commission (NCR) decided that the Next Generation Nuclear Plant (NGNP) would be the Very High Temperature Reactor (VHTR). In support of the licensing and validation effort of the VHTR, Oregon State University was tasked with designing, building, and operating a...
