Thermal Rearrangement Of 4-Aryl-4-Hydroxy-2-Cyclobuten-1-Ones And Application Of The Methodology In The Formation Of Benzofuronaphthoquinones And Benzocarbazolequinones, Kimberly Denise Fisher
Graduate Theses, Dissertations, and Problem Reports (ETD)
Cyclobutenediones have proven useful as starting materials for synthesis of highly functionalized biologically relevant molecules. The rearrangement of cyclobutendiones has a wide synthetic scope and can be utilized as a key step in the construction of quinones, benzo[o]isoxazoles, and 3-methylenoxoindoles having a variety of substitution patterns. Construction of these molecules involves thermolysis of 4-hydroxy-2,4-di-aryl-2-cyclobutenones derived from squaric acid ester. In each of the cases the mechanism proceeds through an initial ring opening of the cyclobutene to afford a ketene intermediate that subsequently undergoes a ring closure with various intermolecular nucleophiles. This methodology has been utilized in the construction of an …

Production Of Docosahexaenoic Acid By Crypthecodinium Cohnii Using Continuous-Mode Process, Deniz Inan
Graduate Theses, Dissertations, and Problem Reports (ETD)
Docosahexaenoic acid (DHA), an omega-3 fatty acid found in cold-water fish, has positive health benefits. While the suggested amount of 220 mg/day for adults may be attained by consuming fish, this may increase exposure to environmental pollutants. The heterotrophic marine alga Crypthecodinium cohnii is an important source of DHA because C. cohnii can accumulate lipid greater than 20% of their biomass with a large fraction of DHA (30-50%). Commercially, DHA production by C. cohnii is conducted in large bioreactors (∼100 m3 capacity) using a batch-mode process.

Three Essays On Credit Constraints And Capital Structure, Christine M. Harrington
Three Essays On Credit Constraints And Capital Structure, Christine M. Harrington
Graduate Theses, Dissertations, and Problem Reports (ETD)
The first essay, "Debt Capacity Constraints, Information, and the Pecking Order Model of Capital Structure", investigates why the pecking order model does not appear to describe the financing choices of small and growth firms. The pecking order model predicts debt issues only when a firm has the capacity to absorb new debt and when firm value is relatively predictable. By explicitly controlling for asymmetric information about firm risk, empirical tests support the predictions of the pecking order model for small and growth firms.;The second essay, "The Sensitivity of Investment to Internal Funds When the Costs of External Funds Differ", asks …

Adaptive Frame Selection For Enhanced Face Recognition In Low-Resolution Videos, Raghavender Reddy Jillela
Adaptive Frame Selection For Enhanced Face Recognition In Low-Resolution Videos, Raghavender Reddy Jillela
Graduate Theses, Dissertations, and Problem Reports (ETD)
Performing face detection and recognition in low-resolution videos (e.g., surveillance videos) is a challenging task. To enhance the biometric content in these videos, image-level and score-level fusion techniques can be used to consolidate the information available in successive low-resolution frames. In particular, super-resolution can be used to perform image-level fusion while the simple sum-rule can be used to perform score-level fusion. In this thesis we propose a technique which adaptively selects low-resolution frames for fusion based on optical flow information. The proposed technique automatically disregards frames that may cause severe artifacts in the super-resolved output by examining the optical flow …

Development Of A Micro-Depth Sensing Indentation Technique With Constant Load Control, Ailing Lin
Development Of A Micro-Depth Sensing Indentation Technique With Constant Load Control, Ailing Lin
Graduate Theses, Dissertations, and Problem Reports (ETD)
In material nano- and micro-indentation research, Young's modulus can be obtained based on the initial unloading stiffness of the load-depth curve. The accurate load and displacement measurement as well as high precision position control of the indenter are needed to achieve the required measurement resolution. The application of PZT actuator is often used to perform the indentation experiment. However, conventional PZT controllers can only provide displacement control. Furthermore, each PZT actuator only serves a specific PZT controller using its unique calibration factor. Thus, it is beneficial to develop a controller, which can carry out both load and displacement control algorithm, …
Comparing Virulence Of Cryphonectria Parasitica Isolates Recovered From Portions Of Cultures Or Cankers Established Before Versus Those After Hypovirus Innoculations, William E. Jones
Graduate Theses, Dissertations, and Problem Reports (ETD)
Variable recovery of hypovirulent (HV) and virulent (V) isolates from repeatedly sampled, identical chestnut blight cankers, caused by Cryphonectria parasitica, prompted this study to monitor more closely the isolate recovery over time to determine hypovirulent or virulent status. To meet the objective, laboratory and field experiments were conducted between 1998 and 2000 to recover isolates from cultures and cankers challenged with HV inoculum. Cultural studies demonstrated (1) hypovirus transfer readily occurred to actively growing colony margins, and (2) that established, virulent mycelium one-to-six weeks-old at time was unable to acquire hypovirus. Results from field studies demonstrated a significant difference in …

Effect Of Circulation Control Blowing Slots On Stall Angles Of A 10:1 Elliptical Airfoil, Jonathan Kweder
Graduate Theses, Dissertations, and Problem Reports (ETD)
Circulation control is a high-lift methodology that can be used on the wing of an aircraft. This technology has been in the research and development phase for over sixty years primarily for fixed wing aircraft when the early models were referred to as "blown flaps." Circulation control works by increasing the near surface velocity of the airflow over the leading edge and/or trailing edge of a specially designed aircraft wing using a series of blowing slots that eject high velocity jets of air. The wing has a rounded trailing edge, and ejects the air tangentially, through these slots inducing the …

Bioinformatic Study Of Gamma-Secretase And Its Substrates, Fei Nan
Bioinformatic Study Of Gamma-Secretase And Its Substrates, Fei Nan
Graduate Theses, Dissertations, and Problem Reports (ETD)
gamma-Secretase is an enzymatic complex critical to amyloid formation and other important pathophysiological processes. Non-specific gamma-secretase inhibitors are not ideal for intervention of familial Alzheimer's disease. The four essential include Presenilin (PS1 or PS-2), APH-1, Pen-2, nicastrin (Nct). Also gamma-secretase cleaves a variety of substrates (over 30). But different sites are cleaved even in a single substrate and no consensus sequence for cleavage by gamma-secretase is identified. We hypothesize that consensus compositional sequence (or functional domain) in components of gamma-secretase and/or its substrates should exist during gamma-secretase regulation and specific gamma-secretase inhibitor based on such consensus sequence (or functional domain) …

Slow-To-Warm-Up Temperament In Infancy As A Predictor Of Concurrent And Later Child And Maternal Behaviors, Jessica B. Stoltzfus
Graduate Theses, Dissertations, and Problem Reports (ETD)
Little is known about the slow-to-warm-up infant temperament. The present study evaluated the usefulness of this temperament as conceptualized by Thomas and Chess in predicting child and maternal parenting behaviors, with a particular focus on its conceptual link to child inhibition. Participants were 1,072 mothers and their children in the NICHD Study of Early Child Care. Slow-to-warm-up temperament in infancy did predict later inhibition, p = .000, but not as well as the difficult temperament or the individual temperament subscales of mood and approach. Including maternal sensitivity and stimulation and support increased the prediction of inhibition from the slow-to-warm-up temperament …

Recharge Processes Within The Cacapon Mountain Aquifer, Ridge And Valley Province, West Virginia, Cristine M. Vinciguerra
Graduate Theses, Dissertations, and Problem Reports (ETD)
During the 2006-2007 water year, apparent recharge rates for three streams draining the Cacapon Mountain Aquifer, in the Valley and Ridge Province of northern West Virginia, were estimated using hydrograph separation techniques. The techniques use stream baseflow, dominated by groundwater discharge, as a surrogate for groundwater recharge. Two of the streams draining the aquifer were strike-normal (Rock Gap Run and Breakneck Run) and one was strike-parallel (Sir Johns Run). The strike-normal streams had significantly lower apparent recharge rates (Rock Gap Run: 2.52 in/yr; Breakneck Run: 6.57 in/yr) than the strike-parallel stream (Sir Johns Run: 13.31 in/yr). The large variations in …
