Deposition and Assembly of Magnesium Hydroxide Nanostructures on Zeolite 4A Surfaces Pei Yoong Koh 156 pages Directed by Dr. Amyn S. Teja A deposition precipitation method was developed to produce magnesium hydroxide / zeolite 4A (Mg(OH)2 Z4A) nanocomposites at mild conditions and the effect of processing variables such as precursor concentration, type of base added, an....

Wireless relay can be utilized to extend signal coverage, achieve spatial diversity by user cooperation, or shield mobile terminals from adverse channel conditions over the direct link. In a two-hop multi-input-multi-output (MIMO) amplify-and-forward (AF) relay system, the overall noise at the destination station (DS) consists of the colored noise forwarded from the rel....

Surface-enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI)is one of several proteomics technologies that can be used in biomarker discovery studies. Such studies often have the goal of finding protein markers that predict early onset of cancers such as cervical cancer. The reproducibility of SELDI has been shown to be an issue in the literatur....

Lean premixed combustors are highly susceptible to combustion instabilities, caused by the coupling between heat release fluctuations and combustor acoustics. In order to predict the conditions under which these instabilities occur and their limit cycle amplitudes, understanding of the amplitude dependent response of the flame to acoustic excitation is required. Extensi....

The objective of this research is to understand the design and performance of state-of-the-art silicon-germanium (SiGe) BiCMOS high-frequency circuits for phased- array radar and wireless communication systems operating in extreme environment conditions. This work investigates the performance of RF circuits over a wide- temperature and exposure to a radiation intensive ....

Commercial organic dyes are widely used for cellular staining due to their small size, high brightness, and chemical functionality. However, their blinking and photobleaching are not ideal for studying dynamics inside live cells. An improvement over organics and much larger quantum dots, silver nanodots (Ag NDs) exhibit low cytotoxicity and excellent brightness and pho....

Although widely used, little is known about the nature of expertise involved in functional task analysis, methods used to discover and represent a task structure in terms of goals and subgoals. Training studies indicated that learning task analysis is not trivial. To counter the task analysis is an art explanation, this dissertation approached task analysis as a skill a....

Solid oxide fuel cells (SOFC) in a flat-plate configuration require a hermetic seal between the fuel and air sides of the electrodes, and this seal must withstand a variety of thermally-induced stresses over the lifetime of the cell. In this study, quantitative microstructure-property relationships are developed to predict optimum seal structures for mechanical properti....

Atherothrombosis can induce acute myocardial infarction and stroke by progressive stenosis of a blood vessel lumen to full occlusion. The goal of this research is to determine what shear rates are pertinent to an occluding blood vessel, the rate of thrombus growth relative to wall shear rates, and to develop a predictive model for estimating length of time to thrombus o....

A series of accident simulations were performed using INLs thermal hydraulics code RELAP5-3D to analyze steady-state and transient behavior of a sodium cooled fast reactor. The reactor chosen for this study was General Electrics S-PRISM, which is a 1,000 MWt pool-type sodium-cooled fast reactor, designed for either an Oxide or Metal fueled core. Once key core characteri....

Identification and Characterization of Diatom Kinases Catalyzing the Phosphorylation of Biomineral Forming Proteins Vonda Chantal Sheppard 151 Pages Directed by Dr. Nils Kröger Diatoms are unicellular photosynthetic algae that display intricately patterned cell walls made of amorphous silicon dioxide (silica). Long-chain polyamines and highly phosphorylated proteins, s....

This dissertation focuses on two distinct relationships: 1) classroom peer ability and student end-of-course test outcomes and 2) school tracking policy and student end-of-course test outcomes. Utilizing the education production function and hierarchical linear models, this dissertation contributes to the literature in the field of public policy by extending the work of....
