Background: Malocclusion can affect an individual's quality of life. Unfortunately, access to orthodontic treatment is limited for many children. Access is improved when orthodontists select practice locations where their services are most needed....
Accelerated life testing; Reliability (Engineering); Service life (Engineering)
This dissertation is focused on finding lower confidence limits for the reliability of systems consisting of Wei bull components when the reliability demonstration testing (RDT) is conducted with zero failures. The usual methods for the parameter...
Conducting polymers; Polymers in medicine; Myocardium
Hydrophilic and conductive characteristics in polymers are mutually exclusive of each other. Hydrophilic polymer properties allow absorption of water up to several magnitudes above their dry weight. However, due to their molecular structure, they...
For more than a hundred million years, male plethodontid salamanders have
utilized non-volatile, proteinaceous courtship pheromones to regulate female mating
receptivity and promote mating success. These pheromones - which are delivered...

Drug resistance in microorganisms; Salmonella typhimurium
Salmonella enterica serovar Typhimurium is an enteric pathogen capable of infecting
a wide range of hosts. The manner in which this pathogen is able to interact with its
host is difficult to define, as is the case with most microbes. Through the...
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...
Dropout behavior, Prediction of; Nontraditional college students; College dropouts; Academic achievement
For more than 100 years, nearly half of all undergraduate students have failed to persist to degree completion (ACT, 2010; Tinto, 1993; U.S. Department of Education, 2008). To make matters worse, adult students have consistently been victims of...
