Background: Helicobacter pylori (Hp) establishes life-long gastric infection in billions of humans, and is often responsible for diseases such as peptic ulcer and gastric cancer. Cumulative actions of genetic drift and natural selection over...
This study is a historical analysis of reasons and dynamics behind the emergence of fundamentalist religious movements. Its purpose is to develop a new conceptual apparatus to the approach toward religious fundamentalist movements that would...
Falls (Accidents); Children's accidents; Children--Wounds and injuries; Child abuse--Investigation
Pediatric short-distance falls, especially from beds or other furniture, are common
false histories given by caretakers to cover up abusive trauma. However, short-distance
falls are also a common occurrence in young children. Knowledge of the types...
In blood coagulation, the serine protease thrombin is a multifaceted enzyme that interacts with multiple proteins. Thrombin utilizes two anion binding exosites (ABE-I and II) to supplement binding to fibrinogen and to the platelet receptor GpIbα,...
Drug resistance in microorganisms--Mathematical models; Intensive care units
Antibiotic resistance is a problem causing growing concern in the medical community, leading some to speculate that a return to the preantibiotic era is imminent. The problem of antibiotic resistance is particularly significant in the intensive...
Metastasis is a complex process requiring directed migration of metastatic cells to favorable microenvironments. Increased CXCR4 expression has been implicated in more invasive, aggressive and metastatic tumor phenotypes and poor patient survival...
This dissertation explores the physical and biological factors that control zooplankton population growth rates in the Ohio River (USA). I employed both observational studies and a mesocosm experiment to ascertain zooplankton population and...
Representing the complex data in a concise and accurate way is a special stage in data mining methodology. Redundant and noisy data affects generalization power of any classification algorithm, undermines the results of any clustering algorithm and...
This work presents a novel comprehensive effort to understand the fluid dynamics within orbiting dishes and the effects of the resulting oscillating fluid flow on shear and endothelial cellular responses within the dishes. It is well documented...
Business logistics; Production management; Manufacturing processes; Industrial efficiency
In today's competitive business environment, companies face enormous pressure and must continuously search for ways to design new products, manufacture and distribute them in an efficient and effective fashion. After years of focusing on reduction...
Wind power has the potential to provide access to electricity to areas lacking the resources to create industrial power plants, as well as supplement residential energy supplies. The low resource investment and ease of installation make it ideal...
Orbital shakers are commonly used in the cell culture industry due to their ease of use, but the fluid dynamics of this system have not been extensively modeled as the system is difficult to quantify analytically. It is desirable to understand how...
Vertical axis wind turbines (VAWTs) are devices to convert wind energy into electricity. Unlike horizontal axis wind turbines (HAWT) where the main rotor shaft is set horizontally, VAWTs use vertical rotor shaft. Unlike HAWTs, VAWTs can be...
Parasites; Medical parasitology; Parasitic diseases
This thesis investigated infection dynamics of parasitic nematodes at both the population
and individual levels by exploring evolutionary and historical aspects of infection as well
as how host-parasite interactions influence virulence. In...
Technical writing; English language--Study and teaching--Foreign speakers; Academic writing--Study and teaching
This dissertation examines how nonnative English speaking (NNES) faculty and
students in engineering respond to language variation and how that response influences
their teaching and learning of academic writing. Using grounded theory approach...
This dissertation is a participatory action research project with adults with mental retardation who reside in Louisville, Kentucky. It explores some of the history and ideologies that frequently have hindered persons with mental retardation from...
Stringed instruments--Instruction and study; Music teachers--Kentucky
The purpose of this study was to identify the teaching techniques of current string
teachers within the Kentucky Music Education Association. Participants (N=31)
completed a 17-question survey that focused on teaching techniques they use...
This thesis looks at the optimization of fluid flow and mass transfer using computational fluid dynamics (CFD) in a micro fluidic coulter counter. CFD will be used to solve equations of fluid flow and mass transfer to see how molecules within the...
Wind energy provides an attractive power source as an alternative to fossil fuels because it is abundant, clean, and produces no harmful emissions. To extract more energy from the wind we need to increase the wind turbine size. However, the...
Previous experimental studies on static, bio-inspired corrugated wings have shown that they produce favorable aerodynamic properties such as delayed stall compared to streamlined wings and flat plates at high Reynolds numbers (Re ≥ 4x104). The...
