Liquor to liquor differences and the effects of liquor feed rate on the distribution of condensed phase combustion products of kraft black liquor solids burned in a laminar entrained-flow reactor

Creator:: Train, Ron
Abstract:: Combustion properties of kraft black liquor solids were studied using a laminar entrained flow reactor. The tendency of black liquors to release fume (compounds containing Na⁺, K⁺, Cl⁻, SO₄²⁻, SO₃²⁻, S₂0₃²⁻ and C0₃²⁻) during combustion were observed at 1000°C. Black liquor solids with a size fraction of 63 to 100...

Modeling slope stability uncertainty : a case study at the Andrews Experimental Forest

Creator:: Murillo, Michelle L.
Abstract:: A simple debris-slide model, employing a digital elevation model (DEM) and geological data, was used in a geographic information system (GIS) to map slope stability in the Andrews Experimental Forest, located in the western Cascade Range in Oregon, USA. To evaluate the contribution of error in elevation to the uncertainty...

Patterns of nitrogen fluxes in watersheds of the H.J. Andrews Experimental Forest, OR

Creator:: Vanderbilt, Kristin Lynn, 1967-
Abstract:: Seasonal and annual patterns of N fluxes and concentrations in streamwater in six conifer-dominated watersheds at the H.J. Andrews Experimental Forest, OR, were studied to gain insight into the factors that influence N retention in this ecosystem. Processes affecting N flux in streamwater differed between organic (DON) and inorganic (DIN;...

Debris flows and flood disturbance in small, mountain watersheds

Creator:: Snyder, Kai U.
Abstract:: This study examined debris flows occurring in a 125 km² study area in the Blue River watershed in the western Cascade Mountains of Oregon over a 50-year period. Debris flow occurrence was found to be concentrated in a distinct zone of high activity occupying approximately half of the study area,...

Effects of input and redistribution processes on in-stream wood abundance and arrangement in Lookout Creek, western Cascades Range, Oregon

Creator:: Dreher, David Marshall
Abstract:: This study explored how selected input and redistribution processes affect the amount and arrangement of in-stream wood within the 64 km2 Lookout Creek watershed in the Andrews Forest, western Cascade Range, Oregon. A longitudinal inventory of in-stream wood was conducted over approximately 20 km of stream length in 2nd to...

Solubility of aluminosilicates in kraft green and white liquors

Creator:: Wannenmacher, P. Nick
Abstract:: The increasing occurrence of aluminosilicate caused complications in krafi pulp mills can be attributed to the closing of purge points and the expanded use of contaminated feedstocks and recycled fiber sources. An active purge of aluminum and silicon from the chemical recovery cycle must be undertaken in order to maintain...

Copper compounds for durable composites : effects on material properties

Creator:: Vidrine, Cheney L.
Abstract:: The effects of incorporation of selected biocides on physical and mechanical properties of aspen strandboard were assessed using five copper-based preservatives or zinc borate at three retention levels. Tebuconazole or 4,5-dichloro-2-N-octyl-4-isothiazolin-3-one (DCOI) were added as co-biocides to selective copper-based treatments. Mold box tests showed that only panels treated with DCOI...

Spawning chinook salmon (Oncorhynchus tshawytscha) two years in a row : reconditioning for repeated gamete collection

Creator:: Mayer, Kent Corey
Abstract:: Spring chinook salmon, Oncorhynchus tshawytscha, in the Snake River Basin are listed as endangered under the Endangered Species Act. The typical life history of spring chinook salmon is semelparous. An experiment was performed to see if mature male spring chinook salmon parr could be reconditioned after hand-spawning and spawned in...

Development of novel spray coated soft elastic gelatin capsule sustained release formulations of nifedipine, bioavailability and bioequivalence of verapamil HCL controlled release formulations, pharmacokinetics of terbinafine after single oral doses in raptors

Creator:: Fahmy, Sahar Abd El-Sattar
Abstract:: This dissertation describes the development of a new sustained release formulation of nifedipine. The new formulation was developed by coating commercially available immediate release soft elastic gelatin capsules using a spray coating technique with two different polymeric combinations. Dissolution studies were conducted and showed that controlled release of nifedipine was...

Preparing sustained release dosage forms of nifedipine by hot-melt coating method

Creator:: Le, Hang Thi
Abstract:: A nifedipine sustained release dosage form was prepared by using hot-melt batch coating. Substrates are sugar beads, mesh size 30-35. Stearic acid, Acid Triglyceride, and carnauba wax were coating agents used to make single layer coated beads and multiple layer coated beads containing nifedipine. Dissolution of nifedipine from the beads...
