Effects of fall lifting and long-term freezer storage on ponderosa pine seedling physiology and quality

Creator:: Omi, Steven Katsu
Abstract:: Two-year-old ponderosa pine (Pinus ponderosa Dougl. ex Laws.) seedlings from two Oregon seed sources were lifted three times in the fall, stored below freezing (-1.5°C), and compared to seedlings that were handled conventionally (spring lifting followed by short-term cold storage, 2-4°C). Based on patterns of budbreak in a greenhouse and...

Seed set and the proportion of progeny due to self-fertilization in a Douglas-fir seed orchard

Creator:: Omi, Steven Katsu
Abstract:: The effects of clonal variability, crown position of cones, and top-pruning of ramets to reduce height growth, on 1) the proportion of viable self-fertilized progeny (s) and 2) the proportion of filled seeds (PF), were investigated in a 20 year-old Douglas-fir (Pseudotsuga menziesii [Mirb.1 Franco) seed orchard. Cones were collected...

Digital Fourier Holographic Microscopy and Potential Applications Towards the Design of Photodynamic Therapy of Osteosarcoma

Creator:: Rossi, Vincent Michele
Abstract:: This work entails both imaging and therapeutic applications of biomedical optics. In both contexts, an understanding of light transport in tissues is necessary. An overview of optical transport in tissues is given, including scattering theory. Digital Fourier holographic microscopy is introduced and applied as a means of metrology via optical...

Nutritional and managerial considerations for wintering beef cattle in the northern Great Basin

Creator:: Brandyberry, Steven D.
Abstract:: A study was conducted to determine effects of year and season on diet quality of beef cattle grazing northern Great Basin rangelands from 1990 to 1993. Forage quality was high early in the growing season, then declined as seasons progressed (P<.05). Plant chemical composition was higher early in the growing...

Rockfish assessment studies on Heceta Bank, Oregon, 1980-81. Sub-project annual report: October 1, 1980 to March 1, 1982

Creator:: Johnson, Steven L., Barss, William H., and Demory, Robert L.
Abstract:: From January 1980 to January 1981 approximate monthly sampling of a unique rockfish (Scorpaenidae) fishing area on Heceta Bank, Oregon was undertaken using acoustic techniques and trawling aboard chartered commercial fishing vessels. Rankings of density of fish sign observed on acoustic transects were regressed against selected environmental variables. Acoustic abundance...

Prompt gamma neutron activation analysis of niobium for characterization of light interstitials

Creator:: Love, Ian J.
Abstract:: High purity niobium metal is used in the construction of superconducting radio frequency (SRF) cavities in superconducting particle accelerators, such as the Large Hadron Collider (LHC) at CERN or the Spallation Neutron Source (SNS) at Oak Ridge National Laboratory. The usual method for characterizing the impurities in this niobium, the...

Measurement of 239Pu, 237Np, and 238U Fission Product γ Rays

Creator:: Tamashiro, Aaron S.
Abstract:: Fission product yields (FPYs) are used for a wide range of applications including nuclear fission theory, nuclear reactor design, reactor antineutrino anomaly, stellar nucleosynthesis, and nuclear forensics. These applications rely on FPYs that were last evaluated in 1993, which included measurements from all over the world up until 1993. In...

Bridging Ways of Knowing to Model the Dynamics of Fire as an Ecocultural Process on Frequent Fire Landscapes of the Pacific Northwest

Creator:: Greenler, Skye M.
Abstract:: Wildfire impacts have intensified in many ecosystems across the western United States due to the combined impact of fire exclusion, climate change, and land management practices. However, on many of these landscapes, fire is a fundamental ecological process that has shaped vegetation structural and compositional diversity, ecosystem function, landscape pattern,...

Social science in fuel management : an annotated bibliography on prescribed fire

Creator:: Kumagai, Yoshitaka, Daniels, Steven E., Oregon State University. College of Forestry, and Oregon State University. Forest Research Laboratory
Abstract:: This annotated bibliography is collected from professional journals in natural resource management and sociology, conference proceedings, and technical reports. It is categorized into thirteen sections: acceptability, fire in wilderness, general, history, institutions, media, policy, public attitude toward wildfire, public involvement, public perception of prescribed burning, risk perception, social psychology, and...

Dynamics and control of continuous crystallizers

Creator:: Leu, Lii-ping
Abstract:: The theoretical analysis of an unseeded, isothermal mixed-suspension mixed-product-removal (MSMPR) crystallizer with a fines trap is developed. The lumped parameter system equations are presented for a homogeneous nucleation and a number-dependent secondary-nucleation model. Linear stability analysis and system simulations are used to investigate the system's dynamic behavior. Modal control algorithms...
