Water content and electrical conductivity profile measurements for dispersive media using enhanced time domain and frequency domain models

Creator:: Flugstad, Benjamin A.
Abstract:: Water conservation and water quality are rapidly increasing in importance in all areas of the world. The ability to accurately measure soil water content and salinity, over a wide variety of conditions, is key to meeting this need. A set of forward prediction models and waveform interpretation algorithms to extract...

Pyrethroid insecticide interaction with the GABAA receptor and the peripheral-type benzodiazepine receptor of rainbow trout brain

Creator:: Eshleman, Amy J.
Abstract:: The peripheral-type benzodiazepine receptor (PTBR) of trout brain was pharmacologically characterized and pyrethroid interaction with this site investigated. High-affinity binding sites for [³H]PK 11195 were detected in brain membranes of rainbow trout; these shared some of the characteristics of the PTBR of rodent brain (i.e., high affinity for PK 11195...

New bounds and constructions for error control codes

Creator:: Al-Darwish, Nasir Ali
Abstract:: The bulk of the theory on error control codes has been developed under the fault assumption of random (symmetric) errors, where 1 → 0 and 0 → 1 errors are equally likely. In the past few years, several applications have emerged in which the observed errors are highly asymmetric. This...

Evaluation of bacterial community indicators of stream sanitary and ecological condition

Creator:: Bracken, Caragwen L.
Abstract:: The focus of this research was to develop bacterial community indicators of stream sanitary and ecological condition. The first study compared substrate utilization patterns between centrifuged and uncentrifuged split samples. We found a shift in the relative proportion of each group of bacteria following centrifugation, with a marked increased in...

Modeling and characterization of hemt devices

Creator:: Chang, Chujyh
Abstract:: Different gate length (0.5 μm 16 μm) Al GaAs/GaAs and AIGaAs /InGaAs High Electron Mobility Transistors were electrically characterized in order to compare the room temperature DC device performance with one-dimensional device models. Model parameters such as the channel mobility and source/drain series resistances are extracted from independent measurement of...

Development, characterization, and piezoelectric fatigue behavior of lead-free perovskite piezoelectric ceramics

Creator:: Patterson, Eric Andrew
Abstract:: Much recent research has focused on the development lead-free perovskite piezoelectrics as environmentally compatible alternatives to lead zirconate titanate (PZT). Two main categories of lead free perovskite piezoelectric ceramic systems were investigated as potential replacements to lead zirconate titanate (PZT) for actuator devices. First, solid solutions based on Li, Ta,...

Optical, electronic, and thermodynamic properties of layered mixed anion compounds

Creator:: Vielma, Jason Michael
Abstract:: Mixed anion compounds that form ZrCuSiAs-type crystal structures exhibit remarkable properties such as superconductivity at low temperatures, hole conduction with optical transparency in the visible region, and exciton absorption at room temperature. In this thesis, properties of a selected group of materials out of the very large set of mixed...

Effect of pharmaceuticals and natural products on multidrug resistance mediatedtransport in Caco-2 and MDCKII-MDR1 drug transport models

Creator:: Fan, Ying
Abstract:: This thesis details my investigation of some pharmaceuticals and natural products on the transport of drugs which are substrates of P-glycoprotein (P-gp), such as cyclosporin A (CSA) and digoxin by using Caco-2 and MDCKII-MDR1 drug transport models. Three objectives were performed to address this goal. The first objective was to...

Preliminary investigation of microbial indicators in the assessment of Oregon streams

Creator:: Campbell, Heidi M. K.
Abstract:: The Environmental Monitoring and Assessment Program (EMAP) site selection protocol was used to generate a random sample of streams throughout the state of Oregon. One hundred and forty-six selected streams were sampled during the summer, low-flow period of 1997. Traditional microbial public health indicators, including heterotrophic plate counts (HPC), total...
