Modeling of sulfate reduction in an entrained-flow black liquor gasifier

Creator:: Jivakanun, Narongsak
Abstract:: Black liquor gasification is one of the promising alternatives to eliminate the drawbacks of the conventional recovery unit of the kraft process. A numerical model has been developed to simulate an industrial pilot scale entrained-flow gasifier currently operating at Tampere, Finland. The objective of the model is to investigate the...

Determinants of federal land grazing permit values and dependent livestock ranch values in eastern Oregon and Nevada

Creator:: Iqbal, Muzaffar
Abstract:: The source and nature of permit value and the federal grazing fee debate motivated this dissertation research. There is little doubt that federal grazing permits have value throughout the western United States, but the source of permit value is unclear. A traditional explanation focuses on the capitalized differential between the...

Controls on movement of selected landslides in the Coast Range and western Cascades, Oregon

Creator:: Wong, Bernard Bong-Lap
Abstract:: The movement characteristics of five landslides are compared and interpreted based on records of approximately 10-years duration. Condon landslide in the Oregon Coast Range has consistently exhibited brief (1 - 8 days) movement episodes in wet winter months, separated by long periods of no movement. The translatory movement is probably...

A microcomputer software package for simulation of non-ideal aqueous electrolyte systems at equilibrium

Creator:: Sinquefield, Scott A.
Abstract:: The non-ideal aqueous electrolyte simulator (NAELS) is composed of three major parts: a Newton-Raphson non-linear optimization program written by Weare, et al (1987); an activity coefficient subroutine for non-ideal electrolyte systems based on Pitzer's model; and an extensive, user expandable database. It is robust, stable, and requires neither thermodynamic data...

Fire history, fire regimes, and development of forest structure in the central western Oregon Cascades

Creator:: Weisberg, Peter J.
Abstract:: Fire history and fire regimes were reconstructed for a 450 km² area in the central western Oregon Cascades, using tree-ring analysis of fire scars and tree origin years at 137 sampled clearcuts. I described temporal patterns of fire frequency, severity, and size, and interpreted topographic influences on fire frequency and...

Flux of ground water and nitrogen through the floodplain of a fourth-order stream

Creator:: Wondzell, Steve
Abstract:: Changes in the concentrations of dissolved ammonia (NH4+1), nitrate (NO3-1), organic nitrogen (DON) were monitored along ground water flow paths to determine the importance of the ground water system to the stream nitrogen budget. The study site was located on a wide floodplain along a fourth-order stream in the Oregon...

Historical fire regime in the Little River watershed, southwestern Oregon

Creator:: Van Norman, Kelli J.
Abstract:: Disturbances are a prevalent and important part of ecosystems. Many landscape patterns that we find today were created, maintained, and changed by natural disturbance regimes. This is especially true for fire, which has historically been a common, natural disturbance in the western U.S forests and grasslands and many other parts...
