Hydrodynamic effects of particle chaining in liquid-solid magnetofluidized beds : theory, experiment, and simulation

Creator:: Cruz-Fierro, Carlos Francisco
Abstract:: In a fluidized bed of magnetically susceptible particles, the presence of a magnetic field induce the formation of particle chains due to interparticle magnetic forces. The resulting effect is a change in the overall spatial distribution of the particles, transitioning from a random, isotropic distribution to an ordered, anisotropic distribution....

Factors influencing halogenated monoterpene production in microplantlets derived from the red macroalga Ochtodes secundiramea

Creator:: Polzin, Jason
Abstract:: Halogenated monoterpene production by the red macroalga Octhodes secundiramea was studied-under different levels of nutrient, bromide, vanadium and light delivery. The key products formed were identified as myrcene, betaelemene, the Z and E isomers of l0-bromomyrcene, 3-chloro-10E-bromomyrcene, Apakaocthodene A, and isomers of chloromyrcene and dibromomyrcene. The proposed pathway begins with...

Social capital in engineering education

Creator:: Brown, Shane
Abstract:: A theoretical argument is presented to suggest that engineering curriculum be designed to develop social capital. Additionally, the value of social capital in the retention of students in the College of Engineering, and the development, role, and value of social capital in an electrical engineering laboratory is evaluated. Data collected...

Variation in female reproductive success in amphibians

Creator:: Dyal, Leslie A.
Abstract:: My dissertation focuses on the factors that influence variation in female reproductive success in plethodontid salamanders and in toads. Variation in reproductive success fuels evolutionary change. Although, females often have been overlooked in studies of reproductive success due to perceived lower levels of variation when compared to variation in male...

Integrating fleets, markets and ocean dynamics : a bioeconomic analysis of the Oregon ocean shrimp fishery

Creator:: Gallagher, Charmaine Marie
Abstract:: Questions relating to economic performance, biological conservation and variation in resource abundance and harvest of ocean shrimp have led to increasing pressure for management action. Developing effective management policies for this highly variable resource requires a comprehensive understanding of the fishery and marine processes. Important factors in understanding the fishery...

Precursors for mitochondrial DNA replication : metabolic sources and relations to mutagenesis and human diseases

Creator:: Song, Shiwei
Abstract:: It is well known that the mitochondrial genome has a much higher spontaneous mutation rate than the nuclear genome. mtDNA mutations have been identified in association with many diseases and aging. mtDNA replication continues throughout the cell cycle, even in post-mitotic cells. Therefore, a constant supply of nucleotides is required...

Quantifying in situ β-glucosidase and phosphatase activity in groundwater

Creator:: Radakovich, Karen M
Abstract:: Enzymes play an important role in the environment, they breakdown natural-occurring and anthropogenic molecules so that they can be transported into cells and utilized. Enzyme assays are routinely used in soil science and oceanography to measure the activities of specific processes and to serve as general indicators of microbial activity....

State legislators' knowledge and perceptions of medical savings accounts and the U.S. health care system : identifying future compromises to health care reform

Creator:: Bonetto, Michael J.
Abstract:: As researchers, policymakers and employers begin focusing on consumer driven health plan models and medical savings accounts (MSAs), a better understanding of the political viability of such reform initiatives is necessary. The purpose of this study was to survey state legislators' knowledge and perceptions of medical savings accounts (MSAs) and...

Jointed goatgrass (Aegilops cylindrica Host) genetic diversity and hybridization with wheat (Triticum aestivum L.)

Creator:: Gandhi, Harish Tulshiramji
Abstract:: Jointed goatgrass (Aegilops cylindrica Host; 2n=4x=28; CCDD) is an agriculturally important species both as a weed and as a genetic resource for wheat (Triticum aestivum L.; 2n=6x=42; AABBDD) improvement. In order to better understand the evolution of this species, the diversity of Ae. cylindrica was evaluated along with its progenitors,...

Toward the development of analysis of students' cognitive processes in an online course

Creator:: Shieh, Ruey S.
Abstract:: This study examined a web-based undergraduate course structured around social learning theories through the lens of social construction as a theoretical framework and a case study research method. The purpose of the study was to investigate students' learning experiences from a cognitively guided research framework. Instructional strategies practiced in the...

Monte Carlo random walk simulation as a complement to experimental and theoretical approaches : application to mass transfer in fish muscle tissue

Creator:: Almonacid-Merino, Sergio Felipe
Abstract:: Mass transfer processes in food systems, such as solute infusion, are poorly understood because of their complex nature. Food systems contain porous matrices and a variety of continuous phases within cellular tissues. Mass transfer processes are generally not pure diffusion: often convection, binding and obstructing diffusion will occur. Monte Carlo...

Finite sample performance of nonparametric regression estimators : the case of additive and parametric covariance models

Creator:: Yang, Ke
Abstract:: This dissertation is composed of three essays regarding the finite sample properties of estimators for nonparametric models. In the first essay we investigate the finite sample performances of four estimators for additive nonparametric regression models - the backfitting B-estimator, the marginal integration M-estimator and two versions of a two stage...

Enhancement of cold tolerance in tomato plants by genetic engineering of glycinebetaine biosynthesis

Creator:: Park, Eung-Jun
Abstract:: Tomato [Lycopersicon esculentum Mill.] plants are chilling sensitive and do not naturally accumulate glycinebetaine (GB), a metabolite that functions as a stress protectant in plants. While GB can increase tolerance of tomato plants to salt and drought stresses, its effect on chilling tolerance has not been examined. To evaluate whether...

The effects of three knowledge interventions on novice volunteer tutors' teaching performance with children with developmental disabilities in a motor development lab setting

Creator:: Tindall, Daniel William Sanchez
Abstract:: According to Block (1999), the greatest problem with inclusion in physical education is the lack of personnel support. Most help comes in the form of teacher assistants such as peer-tutors and paraprofessional who receive very little, if any, direction from the general physical education teacher. However, what remains unknown are...

Creator:: Lins, Ryan D.
Abstract:: Small broomrape (Orobanche minor) is a parasitic weed that attaches to the roots of red clover (Trifolium pratense). Small broomrape invasion presents a significant threat to the future of red clover seed production in Oregon. This study was conducted to investigate and develop small broomrape management options for red clover...

Observational studies of stable nocturnal boundary layers: intermittent turbulence, sensible heat budgets and observational errors

Creator:: Nakamura, Reina
Abstract:: Atmospheric boundary layers become stably stratified at night over land when the surface becomes colder than the air layer above. In stable nocturnal boundary layers (SNBL), turbulence becomes weak and intermittent, terrain-induced phenomena such as drainage currents or gravity-waves emerge and the surface heterogeneity is enhanced. Because of their complexity...
