On the spectra of Schrödinger and Jacobi operators with complex-valued quasi-periodic algebro-geometric coefficients
(University of Missouri--Columbia, 2005)
In this thesis we characterize the spectrum of one-dimensional Schrödinger operators. H = -d2/dx2+V in L2(R; dx) with quasi-periodic complex-valued algebro geometric, potentials V (i.e., potentials V which satisfy one ...
Structural studies of PMM/PGM from Pseudomonas aeruginosa
(University of Missouri--Columbia, 2005)
The human pathogen Pseudomonas aeruginosa expresses a variety of cell surface polysaccharides, including alginate, lipopolysaccharide (LPS), and rhamnolipid. P. aeruginosa is the primary cause of chronic lung infections ...
Religious involvement, attitudes toward seeking professional psychological help, and preferences for alternative mental health settings
(University of Missouri--Columbia, 2005)
Religion is an important diversity variable; however, it is an understudied area in psychology. The purpose of this study was to explore ways that religious factors interact with help-seeking attitudes as well as preferences ...
Energy metabolism and uranium (VI) reduction by Desulfovibrio
(University of Missouri--Columbia, 2005)
Sulfate reducing bacteria (SRB) of the genus Desulfovibrio can breathe uranium in a manner similar to the way in which we (human beings) breathe oxygen. In respiration, we transfer electrons from food to oxygen, producing ...
Distributional estimates for multilinear operators
(University of Missouri--Columbia, 2005)
We prove that if a multilinear operator and all its adjoints map L1 x x L1 to L1/m,oo, then the distribution function of the operator applied to characteristic functions of sets of finite measure has exponential decay at ...
Eye-tracking investigations of lexical ambiguity
(University of Missouri--Columbia, 2005)
The visual world paradigm was used to investigate the time course of ambiguity resolution. Typically, the visual stimuli consisted of one picture that was semantically related to the dominant meaning of an ambiguous word, ...
Source localization using TDOA with erroneous receiver positions
(University of Missouri--Columbia, 2005)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Source localization has been an active research for several years. It has applications in many areas such as geolocation and mobile user location. ...
Automating database curation with workflow technology
(University of Missouri--Columbia, 2005)
Building scientific databases is extremely difficult and expensive. Costs could be reduced if the experts who curate the deposited data, are provided with data that are reviewed by other experts at lower levels for accuracy ...
Flammability characterization of fat and oil derived phase change materials
(University of Missouri--Columbia, 2005)
Phase change materials are a quickly growing commodity in a world which now places a premium on energy conservation, and renewable energy sources. The implementation of PCMs into several world markets can lead to reduced ...
Transport, network, and data link layer protocol designs to improve geo-stationary Earth orbit satellite data set transmission performance
(University of Missouri--Columbia, 2005)
Geo-stationary earth orbit (CEO) satellites are wireless transmission media that provide near-earth Internet and Intranet data communication, but are limited to low Megabits per second transmission rates and small messages. ...
Bioinformatics of protein bound water
(University of Missouri--Columbia, 2005)
Protein-bound water molecules are important components of protein structure, and therefore, protein function and energetics. Here we present a semi-automated computational approach for identifying conserved (i.e. structurally ...
Teacher perceived impact of technology on elementary classrooms and teaching
(University of Missouri--Columbia, 2005)
Issues surrounding technology integration are varied. Over the last decade, the presence of technology in elementary classrooms has increased; however, research indicates that many teachers are not utilizing these resources ...
Mechanical properties of complex biological systems using AFM-based force spectroscopy
(University of Missouri--Columbia, 2005)
An atomic force microscope (AFM) was designed and built to study the mechanical properties of small collagen fibrils and the plasma membrane of living cells. Collagen is a major component of bone, skin and connective ...
P2Y[subscript 2] nucleotide receptor up-regulation and function in submandibular gland epithelium
(University of Missouri--Columbia, 2005)
Sjögren's syndrome (SS) is an autoimmune disease that specifically targets exocrine glands, including salivary glands, and results in an impairment of secretory function. P2Y₂ nucleotide receptors for extracellular ATP ...
Anion and solvent influences on the self-assembly of copper(I) coordination solids
(University of Missouri--Columbia, 2005)
The investigation of solvent and anion influences on the self-assembly of copper(I) coordination solids are presented. As these extended solids vary in structural design as reactions conditions are varied, both those ...
Teacher collaboration and school reform: distributing leadership through the use of professional learning teams
(University of Missouri--Columbia, 2005)
This dissertation reports a study of two professional learning teams of teachers at one Midwestern secondary school implementing a hybrid school improvement process incorporating elements of several reform models. A ...
A defense of Alvin Plantinga's evolutionary argument against naturalism
(University of Missouri--Columbia, 2005)
Alvin Plantinga argues that naturalism it is irrational for a reflective person to hold to the doctrine of naturalism. If naturalism is true, some evolutionary doctrine must also be true and our evolutionary history must ...
Influences of anxiety on golf performance: a field test of catastrophe theory
(University of Missouri--Columbia, 2005)
The purpose of this study was to test the basic tenets of Fazey and Hardy's (1988) catastrophe model. Specifically, the purpose was to examine the interaction effects of cognitive anxiety (worry) and physiological arousal ...
