The following paper is an objective view on the viability of growing the truffle Tuber melanosporum in the Willamette Valley. Included in this study are the history of the truffle, biological cycle, habitat description, method of cultivation and an enterprise budget for commercial production in the Willamette Valley. The truffle,...
The perception of a long-term cost advantage of synthetic infill turf systems relative to natural grass systems has contributed to a rise in their popularity in the USA. However, few comprehensive cost assessments of natural grass and synthetic infill systems exist. There are also no studies looking at interactions between...
Agricultural water supplies are becoming increasingly uncertain in the western United States due to rising demand from competing water users, environmental restrictions on surface water withdrawals due to water quality and endangered species concerns, and, potentially, climate-induced hydrological changes. Since many rural areas in the West depend economically upon irrigated...
Purebred Jersey steers are often overlooked for beef production due to the perceived poor growth and production. Currently dairy persons marketing their steer offspring are receiving minimal compensation due to lack of demand by beef feeders and a saturated veal market. Twenty purebred Jersey steers were used to evaluate lifetime...
The photoneutron production from three Varian linear accelerators ranging in energies from 6 MV to 23 MV has been investigated. Photoneutrons are produced during (γ, n) interactions with materials located within the treatment head. These unwanted neutrons not only increase patient dose, but may also lead to the requirement of...
Wheat (Triticum aestivum L.) is one of the major crops produced in the U.S. Pacific Northwest, a region known for its wheat production for international export. Wheat production in the region is threatened by diseases such as Cephalosporium stripe and stripe rust. Cephalosporium stripe is a vascular wilt disease of...
This research was conducted on three study areas on elk winter
ranges in Northeast Oregon. One was on the Starkey Experimental
Forest and Range and the others were in the same vicinity. Plant
appendages, spring and fall defoliation and fall growth of bluebunch
wheatgrass were evaluated in terms of quality...
Italian ryegrass populations have been identified with evolved resistance to glyphosate in orchards with a history of glyphosate use. Two of these populations were selected to investigate the inheritance of glyphosate resistance. The mechanisms involved in the herbicide resistance were an altered target site for the population SF and reduced...
In this work a prompt gamma neutron activation analysis (PGNAA) facility has been designed, built, and characterized at the Oregon State University TRIGA® reactor. PGNAA is a technique used to determine the presence and quantity of trace elements such as boron, hydrogen and carbon which are more difficult to detect...
Designing spectral efficient, high-speed wireless links that offer high quality-
of-service and range capability has been a critical research and engineering challenge. In this thesis, we mainly address the complexity and performance issues of
channel estimation and data detection in multiple-input multiple-output (MIMO)
orthogonal frequency division multiplexing (OFDM) systems over...
