A plasma polymerization investigation and low temperature cascade arc plasma for polymeric surface modification
(University of Missouri--Columbia, 2006)
The plasma polymerization behavior of fluorocarbon systems was investigated using the monomers C₃F₆, C₂H₂F₄, C₄F₁₀ and C₃F₆O, which were compared to methane and butane, Section III. In Sections V and VII, surface modification ...
Statistical thermodynamics for RNA structures with simple tertiary contacts and pseudoknots
(University of Missouri--Columbia, 2006)
In this thesis, we develop statistical mechanical models for the folding of simple RNA tertiary structures. The focus is on the calculation of the tertiary structure conformational entropy. The key idea of the method is ...
Mechanisms of call recognition in three sympatric species of Neoconocephalus (Orthoptera: Tettigoniidae) : asymmetrical interactions and evolutionary implications
(University of Missouri--Columbia, 2006)
Scientists have debated the hypothesis of reinforcement. Nevertheless, recent empirical and theoretical work have dispelled doubts about its existence. Reinforcement is most often studied by establishing one of its predicted ...
Sharp estimates of the transmission boundary value problem for dirac operators on non-smooth domains
(University of Missouri--Columbia, 2006)
This thesis derives the sharp estimates for the transmission boundary value problems (TBVP) for Dirac operators in Lipschitz domains in the three dimensional setting. Most of the transmission problems considered in the ...
The role of mental-modeling ability, content knowledge, and mental models in general chemistry students' understanding about molecular polarity
(University of Missouri--Columbia, 2007)
This study explored general chemistry students' thinking processes about molecular polarity and related concepts. The study employed a mixed-method design to reveal how general chemistry students use their conceptual ...
Autologous bone marrow-derived mesenchymal stem cell transplantation as a therapy for neuronal ceroid lipofuscinosis
(University of Missouri--Columbia, 2007)
The Neuronal Ceroid Lipofuscinoses (NCLs) are a group of rare genetic diseases characterized by neurodegeneration and accumulation of autofluorescent lysosomal storage bodies in numerous cell types. There are currently no ...
How and in what context do osteopathic medical students learn about interprofessional practice
(University of Missouri--Columbia, 2007)
The purpose of this study was to explore how and in what context osteopathic medical students learn about interprofessional practice. A mixed method design was used to gather data on attitudes of first- and second-year ...
The effect of big four office size on audit quality
(University of Missouri--Columbia, 2007)
Larger offices of Big Four accounting firms are argued to provide higher quality audits than smaller offices due to greater in-house experience and more expertise in ministering the audits of publicly listed clients. In ...
The effects of elevated temperature on preimplantation-stage porcine embryos
(University of Missouri--Columbia, 2006)
It was the objective of these experiments to more fully characterize the biochemical and developmental responses of in vitro-produced preimplantation stage porcine embryos to elevated temperatures. In vitro fertilized (IVF) ...
Impact of alternate host phenology amd alternate hose-transgenic corn interactions on the Western corn rootworm (Coleoptera: Chrysomelidae)
(University of Missouri--Columbia, 2006)
With the increasing adoption of transgenic maize with resistance to rootworms, combined with glyphosate tolerance, as a control tactic for western corn rootworm, Diabrotica virgifera virgifera LeConte, an understanding of ...
Penetration of innovation : taming the unexplored interactions between information, knowledge and persuasion in the innovation-decision model
(University of Missouri--Columbia, 2006)
Building upon Everett Roger's theory of Diffusion of Innovations, foraging into knowledge acquisition theories, and leaning heavily onto the new communication perspectives opened by New Media, the present study aims to ...
The assessment of HIV knowledge and attitudes towards caring for HIV/AIDS patients among senior nursing students in baccalaureate programs in the United States of America and Thailand
(University of Missouri--Columbia, 2006)
This study uses a descriptive, comparative design to examine, describe, and compare HIV knowledge and attitudes towards caring for HIV/AIDS patients among senior baccalaureate nursing students in the United States of America ...
Thick filament regulation of myocardial contraction
(University of Missouri--Columbia, 2006)
The ability of the heart to function as a pump is governed by mechanisms intrinsic to individual cardiac myocytes. The experiments in this dissertation were designed to examine the effects of sarcomere length and thick ...
Building a media agenda on health disparities : how issue perceptions and news values work to influence effectiveness
(University of Missouri--Columbia, 2006)
Building on prior literature conceptualizing the role of public relations in influencing the media agenda, this study proposes a model of agenda building that explores the determinants of the agenda building process and ...
Individual vs. systemic justice : using trust and moral outrage to predict reactions to vigilante murder
(University of Missouri--Columbia, 2006)
Jurors can approach their charge of meting out justice in different ways, two of which include focusing on the outcome of a specific trial and/or focusing on upholding justice more broadly by adhering to procedures and ...
