The bleaching response of kraft pulps from fresh and aged commercial Douglas-fir chips

Creator:: Lai, Jinn-Hsing
Resource Type:: Masters Thesis

Combustion mechanisms in wood fired boilers

Creator:: Tuttle, Kenneth Lewis
Abstract:: A program of research has been established at Oregon State University to study wood residue combustion using an experimental spreader-stoker combustor. This research was conducted to increase the understanding of combustion occurring in wood fired boilers. Using Douglas Fir screened to 3/8-3/4 inches, two 4x4 factorial experiments were conducted varying...

Influence of processing and storage on the phenolic composition of apple, pear and white grape juice

Creator:: Spanos, George A.
Abstract:: Methodology for characterization of the phenolic profile of apple, pear and grape juice was developed. It utilized High Performance Liquid Chromatography (HPLC) for separation of individual phenolic compounds and Diode Array Detection for recording the Ultra-violet (UV) spectrum of chromatographic peaks. The high resolution achieved and the ability of recording...

Mechanisms of resistance in broccoli, Brassica oleracea italica to the garden symphylan, Scutigerella immaculata (Newport)

Creator:: Simagrai, Montri
Abstract:: Studies were conducted on the mechanisms contributing to resistance in broccoli, Brassica oleracea italica, to the garden symphylan, Scutigerella immaculata (Newport). Differences in resistance to symphylan injury were shown between five selected broccoli cultivars. The hybrid cultivars, Crusader, Green Duke and Bravo, showed a higher level of resistance to symphylans...

The concentration of nutrients in the tissue of ten white spruce provenances grown on an acid and a basic soil

Creator:: Gilbert, Roy C. A.
Abstract:: The experiment described in this paper was designed and carried out to study the ability of five provenances of white spruce of acid soil origin and five provenances of basic soil origin grown on an did and a basic soil to utilize and respond to the five macro-nutrient elements N,...

A computer simulation model of seasonal transpiration in Douglas-fir based on a model of stomatal resistance

Creator:: Reed, Kenneth Lee, 1942-
Abstract:: Four study sites were selected along an altitudinal gradient on Mt. Ashland in the Siskiyou Mountains of southern Oregon. The altitudinal gradient roughly corresponded to a gradient in temperature and water availability ranging from very hot and dry to cool and moist. Air and soil temperatures were continuously measured on...

Pacific Coast Groundfish Fishery Assessment and Management: Incorporating Nearshore Surveys into the Fishery Management Framework

Creator:: Haven, Katlyn M. M.
Abstract:: The Pacific coast groundfish fishery is a diverse, important and lucrative commercial and recreational fishery. Part of this fishery’s monitoring process includes regular fishery-independent surveys for stock assessment. Although these fishery-independent surveys are cost-effective, they are susceptible to scientific uncertainty, and they do not currently sample in nearshore (water depth...

Development of a Smartphone App to Easily Measure Extensional Viscosity

Creator:: Swift, Aleesha M.
Abstract:: The measurement of extensional viscosity is important in many chemical, biomedical, agricultural, and engineering applications. The determination of extensional viscosity is generally difficult, expensive, and inaccessible outside of research labs. The development of a smartphone application (app) that could use a phone’s high-speed camera to measure this parameter could open...

Nitrogen 15 studies with nonleguminous nitrogen-fixing plants

Creator:: Webster, Stephen Russell
Abstract:: Snowbrush (Ceanothus velutinus), red alder (Alnus rubra), and bitterbrush (Purshia tridentata) are three important nitrogen- fixing nonleguminous species. They commonly grow in association with commercially important conifers in western United States and conceivably could be utilized to add nitrogen to forest ecosystems. Nitrogen 15 gas was used to study nitrogen...
