Influence of Cholesterol Import on Aspergillus fumigatus Growth and Antifungal Suscepibility

Description: Invasive pulmonary aspergillosis is a life-threatening fungal infection commonly observed in immunocompromised patients and has a mortality rate approaching 100% once the disease is disseminated. Aspergillus fumigatus is the most common pathogen. Early diagnosis improves the prognosis but is very difficult since most signs and symptoms are nonspecific. Antifungal therapy, usually based on sterol biosynthesis inhibitors, is also of limited efficacy. In my attempts to discover a diagnostic st… more

Integrating GIS with Benthic Metrics: Calibrating a Biotic Index to Effectively Discriminate Stream Impacts in Urban Areas of the Blackland Prairie Eco-Region

Description: Rapid Bioassessment Protocols integrate a suite of community, population, and functional metrics, determined from the collection of benthic macroinvertebrates or fish, into a single assessment. This study was conducted in Dallas County Texas, an area located in the blackland prairie eco-region that is semi-arid and densely populated. The objectives of this research were to identify reference streams and propose a set of metrics that are best able to discriminate between differences in community… more

Intelligent Memory Management Heuristics

Description: Automatic memory management is crucial in implementation of runtime systems even though it induces a significant computational overhead. In this thesis I explore the use of statistical properties of the directed graph describing the set of live data to decide between garbage collection and heap expansion in a memory management algorithm combining the dynamic array represented heaps with a mark and sweep garbage collector to enhance its performance. The sampling method predicting the density an… more

Interfacial Electrochemistry and Surface Characterization: Hydrogen Terminated Silicon, Electrolessly Deposited Palladium & Platinum on Pyrolyzed Photoresist Films and Electrodeposited Copper on Iridium

Description: Hydrogen terminated silicon surfaces play an important role in the integrated circuit (IC) industry. Ultra-pure water is extensively used for the cleaning and surface preparation of silicon surfaces. This work studies the effects of ultra-pure water on hydrogen passivated silicon surfaces in a short time frame of 120 minutes using fourier transform infrared spectroscopy – attenuated total reflection techniques. Varying conditions of ultra-pure water are used. This includes dissolved oxygen poor… more

Investigation of the Pressure Dependence of SO3 Formation

Description: The kinetics of the pressure dependent O + SO2 + Ar reaction have been investigated using laser photolysis resonance fluorescence at temperatures of 289 K, 399 K, 581 K, 699 K, 842 K and 1040 K and at pressures from 30-665 torr. Falloff was observed for the first time in the pressure dependence. Application of Lindemann theory yielded an Arrhenius expression of k(T) = 3.3 x 10-32exp(-992/T) cm6 molecule-1 s-1 for the low pressure limit and k(T) = 8.47 x 10-14exp(-468/T) cm3 molecule-1 s-1 for t… more

Description: Voluntary turnover has become a problem for many organizations in today's society. The cost of this turnover reaches beyond organizational impact, but also affects the employees themselves. For this reason, there has been a plethora of research conducted by both academicians and practitioners on the causes and consequences of voluntary turnover. The purpose of this study is to test the validity and generalizability of the job embeddedness model of voluntary turnover to the information technolog… more

Joy Harjo's Poetics of Transformation

Description: For Muscogee Creek poet Joy Harjo, poetry is a real world force that can empower the reader by utilizing mythic memory, recovery of history, and a spiral journey to regain communal identity. Her poetic career transforms from early lyric poems to a hybridized form of prosody, prose, and myth to accommodate and to reflect Harjo's concerns as they progress from personal, to tribal, and then to global. She often employs a witnessing strategy to combat the trauma caused by racism in order to create … more

Management Tools for Prescribed Burning for Tallgrass Prairie Restoration at the Lewisville Lake Environmental Learning Area

Description: The Lewisville Lake Environmental Learning Area (LLELA) is a wildlife management area with tallgrass prairie, an endangered ecosystem. Essential ecosystem processes, especially fire, are part of restoration. To support fire management efforts at LLELA and surrounding areas, this project evaluated and developed tools for fire restoration. The four primary prairie grasses respond favorably to burning. Fuel loads and fuel models vary by scale and survey method. One- and 10-hour fuel moisture can b… more

Modeling of Land Use Change Effects on Storm Water Quantity and Quality in the City of Carrollton and the North Texas Area

Description: Development and population are rapidly increasing in urbanizing areas of North Texas and so is the need to understand changes in storm water runoff flow and its contamination by nutrients, sediment, pesticides and other toxicants. This study contributes to this understanding and has two primary components: first, development of a graphical user interface for a geographic information system and storm water management database, and second, performing a two-scale hydrological modeling approach (th… more

Negotiating Environmental Relationships: Why Language Matters to Environmental Philosophy

Description: The medium of language is important to environmental philosophy, and more specifically, to the establishment and understanding of environmental relationships. The differences between animal and human language point to our unique semantic range, which results from our neuro-linguistic process of signification. An examination of the linguistic implications of the problem of nature and the tenets of semiotics challenges the idea of a clean word to world fit. Because signs are the medium in which m… more

Outer Reaches of the Palindrome

Description: This work is an exploration into the palindrome, both as a literary form and an expression of infinity. The first two chapters address the fascinating manner in which the mind contextualizes fragments of speech and ludicrous grammatical implications that are spawned by the poetic structure of the palindrome (third chapter). The thesis then departs from the literary aspect of the palindrome and focuses in the fourth chapter on structural likenesses in psychology and mythology. The fifth chapter … more

Perceiving Matter in Notes on Space, Undated (Log 3) by André du Bouchet, Fontfroide-le-Haut, Fata Morgana, 2000

Description: This study of the graphic field in notes on space, undated (log 3) focuses on how the white emptiness of a page plays a structural role in the articulation of dissociated fragments of notes. According to the criteria of three theorists (Genette, Lapacherie, Baetens), the distinction between non-linear and tabular proves to be non-exclusive in this particular work. Ostensibly, this non-figurative writing instigates interactive contemplation and lends itself to multiple entries, like an object on… more

Plays of Tennessee Williams as opera: An analysis of the elements of Williams's dramatic style in Lee Hoiby's Summer and Smoke and André Previn's A Streetcar Named Desire.

Description: There are two major, well-known operas based on plays of Tennessee Williams. He refused many times throughout his life to give permission for his play, A Streetcar Named Desire, to be set as an opera. It was not until the 1960s that he granted permission for Lee Hoiby to choose any of his plays as a basis for a new opera. Hoiby chose Summer and Smoke, a play which was written at approximately the same time as Streetcar. Lanford Wilson created the libretto for the opera which was given its pre… more

Police officers: Perception of self, occupational role, and occupational events.

Description: This study examined police officers' perceptions of self, occupational role and their relation to perceived stress and posttraumatic stress symptomology. Self-report measures for the study variables were completed by 101 police officers. Hypotheses predicted that perception of self and role would be associated with perception of stress and that perception of the stress would mediate PTSD symptomology. Neuroticism, job quality and general job satisfaction were the main predictors of stress. Stre… more
