Measuring Dispersion In Laser Cavity Mirrors Using White-Light Interferometry, Allison S. Goodspeed
Theses and Dissertations
Terahertz radiation is an emerging field that has far reaching applications. There is a need for portable and affordable terahertz sources that may be used for detection of structural weaknesses in aerospace composites. One possibility for terahertz generation is a femtosecond Cr:LiSAF laser. However, controlling intracavity dispersion is necessary in order to get the ultrashort pulses needed to generate terahertz radiation. This research measures dispersion of the chirped femtosecond intracavity mirrors by employing white-light interferometry and explains the theory behind the curve-fitting process used to calculate dispersion. To compensate for the narrow reflectivity band of the mirrors, a CaF2 …

Oxygenation Of The Root Zone And Tce Remediation: A Plant Model Of Rhizosphere Dynamics, Ian F. Thompson
Theses and Dissertations
This study analyzes rhizosphere conditions that enhance the effective aerobic degradation of TCE in wetland bioremediation systems. A plant model was built using Stella 9.0 modeling software and uses numerical integration evaluation; it addresses movement of oxygen through plant vascular and aerenchymal systems, and into the rhizosphere where oxygen and other substrates influence bacteria. Methanotrophs and heterotrophs are assumed to be influential bacteria groups. Variations of humidity-induced-convection, methane, soil carbon, and copper concentrations are evaluated. Varying concentrations and hydraulic loadings of TCE are assessed with respect to TCE consumption rate and TCE treatment efficiency. Soil conditions most directly affected TCE …
Dairy Culture: Industry, Nature And Liminality In The Eighteenth-Century English Ornamental Dairy, Ashlee Whitaker
Dairy Culture: Industry, Nature And Liminality In The Eighteenth-Century English Ornamental Dairy, Ashlee Whitaker
Theses and Dissertations
The vogue for installing dairies, often termed "fancy" or "polite" dairies, within the gardens of wealthy English estates arose during the latter half of the eighteenth century. These polite dairies were functional spaces in which aristocratic women engaged, to varying degrees, in bucolic tasks of skimming milk, churning and molding butter, and preparing creams. As dairy work became a mode of genteel activity, dairies were constructed and renovated in the stylish architectural modes of the day and expanded to serve as spaces of leisure and recreation. Dairies were often lavishly outfitted to create a delicate and clean atmosphere, a fancy …
Sedimentological And Biological Analyses On Hobble Creek Prior To Restoration, Jaron Michael Brown
Sedimentological And Biological Analyses On Hobble Creek Prior To Restoration, Jaron Michael Brown
Theses and Dissertations
Hobble Creek is one of several inflowing streams and rivers into Utah Lake, Utah, USA. Historically, June sucker (Chasmistes liorus), a federally listed endemic fish, spawned up all the major inflowing streams and rivers but is now limited to just the Provo River. The State of Utah has recently proposed restoring the lower reaches of Hobble Creek for additional spawning and rearing needs. This restoration effort will likely involve removal of migration barriers, re-aligning the stream, and removing existing levees that prevent floodplain access. These changes have raised several questions that this study aims to answer. First, what are the …

Differences Between Male Perpetrators Of Child Homicide, Isabel Perez-Morina
Theses and Dissertations
The scientific study of child abuse and infanticide is a relatively young practice in the field of medicine, psychiatry and psychology, and although the role of parents in child homicide has been studied, minimal research has focused on the role of the male paramour, or the child's mother's boyfriend, as the perpetrator of child homicides. This study aimed to examine the differences between male paramours and biological fathers who kill children and hypothesized that biological fathers or step-fathers are significantly more likely than the child's mother's male paramour to kill their children due to relationship factors between the perpetrator and …
Gliotoxin Production In Aspergillus Fumigatus, Susan Musyimi
Gliotoxin Production In Aspergillus Fumigatus, Susan Musyimi
Theses and Dissertations
Aspergillus fumigalus is a ubiquitous fungus that causes an infection called aspergillosis in immune-compromised surgery patients (Latge, 2001, 384; Bok et al. 2006). Aspergillosis cases have increased in the past decade due to the increasing number of patients undergoing immunosuppressive therapy and receiving organ transplants (Bok et al. 2006). Although there is still disagreement as to the causative agent of the symptoms accompanying aspergillosis, many scientists suspect that the compound, gliotoxin, plays a major role, hi this study, we compared the amounts of gliotoxin produced from clinical and environmental isolates of A. fumigatus. We hypothesized that the amount of gliotoxin …
