Alkali metal coactivators in SrS: Cu,F thin-film electroluminescent devices

Creator:: Keir, P. D., Wager, J. F., Clark, B. L., Li, D., and Keszler, Douglas A.
Abstract:: A unique approach for obtaining bright and efficient saturated green phosphors for alternating-current thin-film electroluminescent (ACTFEL) device applications is presented. The approach involves color-shifting blue SrS:Cu,F ACTFEL phosphors into the green region of the spectrum via the incorporation of alkali metal ions into the SrS lattice. Alkali metals are incorporated...

Two-scale convergence of a model for flow in a partially fissured medium

Creator:: Clark, G. W. and Showalter, R. E.
Abstract:: The distributed-microstructure model for the flow of single phase fluid in a partially fissured composite medium due to Douglas-Peszyńska-Showalter [12] is extended to a quasi-linear version. This model contains the geometry of the local cells distributed throughout the medium, the flux exchange across their intricate interface with the imbedded fissure...

Current and Potential Tagging and Tracking Systems for Logs Harvested from Pacific Northwest Forests

Creator:: Murphy, Glen, Clark, Joshua A., and Pilkerton, Stephen
Abstract:: The forest industry is constantly changing, and technology is constantly shifting the bar for efficiency and profitability. To maintain competitiveness and control costs in a global market, an efficient log tracking method must be used by regional stakeholders in the log supply chain from stump to mill to end consumer....

Red electroluminescence from ZnGaS:Mn thin films

Creator:: Dimitrova, V., Draeseke, A., Tate, J., Yokoyama, T., Clark, B. L., Keszler, Douglas A., and Tate, Janet
Abstract:: We demonstrate color shifting from the yellow to the red in the electroluminescence from (ZnGa)S:Mn films. We observe threshold voltages down to about 35 V, extremely low for such devices. We discuss the materials characteristics of the phosphor films, and the potential for improvement of the luminous intensity of the...

Stocking Rate and Fuels Reduction Effects on Beef Cattle Diet Composition and Quality

Creator:: Clark, Abe, DelCurto, Tim, Vavra, Martin, and Dick, Brian L.
Abstract:: An experiment was conducted to evaluate the influence of forest fuels reduction on diet quality, botanical composition, relative preference, and foraging efficiency of beef cattle grazing at different stocking rates. A split plot factorial design was used, with whole plots (3 ha) being fuel reduced or no treatment (control), and...

Effect of mid-rotation fertilization on stiffness and strength of loblolly pine wood

Creator:: Antony, Finto, Schimleck, Laurence R., Daniels, Richard F., and Clark, Alexander, III
Abstract:: Trees sampled from a loblolly pine mid-rotation fertilization trial were used in this study. The study was laid out in a randomized complete block design with four levels of nitrogen fertilizer as treatments: control (000N), 112 (112N), 224 (224N), and 336 (336N) kg/ha of nitrogen, with each treatment replicated in...

Relationship Between Wildfire, Salvage Logging, and Occupancy of Nesting Territories by Northern Spotted Owls

Creator:: Clark, Darren A., Anthony, Robert G., and Andrews, Lawrence S.
Abstract:: The northern spotted owl (Strix occidentalis caurina) is one of the most intensively studied raptors in the world; however, little is known about the impacts of wildfire on the subspecies and how they use recently burned areas. Three large-scale wildfires in southwest Oregon provided an opportunity to investigate the short-term...

Survival Rates of Northern Spotted Owls in Post-fire Landscapes of Southwest Oregon

Creator:: Clark, Darren A., Anthony, Robert G., and Andrews, Lawrence S.
Abstract:: We estimated annual survival rates (S) of 23 radio-marked Northern Spotted Owls (Strix occidentalis caurina) at the Quartz and Timbered Rock burns and adjacent areas in southwest Oregon. We used known-fate models in program MARK to test for differences in survival among three groups (owls dwelling inside of burned areas,...

Prescribed fire effects on resource selection by cattle in mesic sagebrush steppe. Part 2: Mid-summer grazing

Creator:: Clark, Patrick E., Lee, Jaechou, Ko, Kyungduk, Nielson, Ryan M., Johnson, Douglas E., Ganskopp, David C., Pierson, Fredrick B., and Hardegree, Stuart P.
Abstract:: Prescribed fire can release herbaceous forages from woody plant competition thus promoting increased forage plant production, vigor, and accessibility. Prescribe fire also consumes standing litter thereby improving forage quality and palatability. Consequently, prescribed fire is commonly considered an effective tool for manipulating livestock distribution on rangelands. Efficacy of this tool...

Prescribed fire effects on resource selection by cattle in mesic sagebrush steppe. Part 1: Spring grazing

Creator:: Clark, Patrick E., Lee, Jaechoul, Ko, Kyungduk, Nielson, Ryan M., Johnson, Douglas E., Ganskopp, David C., Chigbrow, Joe, Pierson, Fredrick B., and Hardegree, Stuart P.
Abstract:: Prescribed fire is commonly applied world-wide as a tool for enhancing habitats and altering resource-selection patterns of grazing animals. A scientific basis for this practice has been established in some ecosystems but its efficacy has not been rigorously evaluated on mesic sagebrush steppe. Beginning in 2003, resource-selection patterns of beef...
