Christine De Pizan's Metaphoric Womb, Tina-Marie Ranalli Dec 2011

Christine De Pizan's Metaphoric Womb, Tina-Marie Ranalli

Medieval Feminist Forum: A Journal of Gender and Sexuality

As a medieval woman writer, Christine de Pizan (ca. 1364-1430) was in an unusual position which necessitated not only that she establish her authority as a vernacular writer, like her male counterparts, but also that she find a way to reconcile her scholarly activity with her sex. In the Livre de la cité des dames, Christine finds a unique solution to her problem of authority and identity. It is my contention that in this work Christine presents an ingeniously crafted and multifaceted metaphor of the development of human life in the womb, what I term her “womb metaphor.” The Cité …


“The Reputation Of The Queen And Public Opinion: The Case Of Isabeau Of Bavaria”, Tracy Adams, Glenn Rechtschaffen Dec 2011

“The Reputation Of The Queen And Public Opinion: The Case Of Isabeau Of Bavaria”, Tracy Adams, Glenn Rechtschaffen

Medieval Feminist Forum: A Journal of Gender and Sexuality

This essay takes issue with a still common tendency to read contemporary criticisms of powerful women as straightforward evidence of their “unpopularity,” using as a cast study Isabeau of Bavaria (1371-1435), who was generally imagined to have suffered the scorn of her contemporaries. In part one of the essay we argue that the two sources that scholars have relied upon prove not that public opinion turned against Isabeau in 1405-1406, but only that her political enemy Jean of Burgundy was planting negative propaganda about her in hopes of damaging her reputation during those years. In part two we consider whether …

Modeling Carbon Fiber Reinforced Polymeric Composite Laminates For Piezoelectric Morphing Structures, Darryl Vincent Murray Dec 2011

Modeling Carbon Fiber Reinforced Polymeric Composite Laminates For Piezoelectric Morphing Structures, Darryl Vincent Murray

Theses and Dissertations

Thin unsymmetric carbon fiber reinforced polymeric(CFRP) composite laminates are examined for use of morphing structures using piezoelectric actuation. During fabrication, unsymmetric laminates are able to deform to more than one post-cure room temperature shape. Thin cross-ply laminates will deform to a cylindrical post-cure room temperature shape while thicker non-cross-ply laminates will deform to a saddle shape. Predictions of the deformed post-cure shape will be made by modeling the cure process using analytical and numerical. These models will then serve as expectations for experimental tests. Modeling the fabrication process allowed for characterizing important data such as residual stresses from the cure …


Static And Free Vibration Analyses Of Composite Shells Based On Different Shell Theories, Ebrahim Asadi Dec 2011

Static And Free Vibration Analyses Of Composite Shells Based On Different Shell Theories, Ebrahim Asadi

Theses and Dissertations

Equations of motion with required boundary conditions for doubly curved deep and thick composite shells are shown using two formulations. The first is based upon the formulation that was presented initially by Rath and Das (1973, J. Sound and Vib.) and followed by Reddy (1984, J. Engng. Mech. ASCE). In this formulation, plate stiffness parameters are used for thick shells, which reduced the equations to those applicable for shallow shells. This formulation is widely used but its accuracy has not been completely tested. The second formulation is based upon that of Qatu (1995, Compos. Press. Vessl. Indust.; 1999, Int. J. …


Static And Vibration Analysis Of Thick Generally Laminated Composite Deep Curved Beams, Mehdi Hajianmaleki Dec 2011

Static And Vibration Analysis Of Thick Generally Laminated Composite Deep Curved Beams, Mehdi Hajianmaleki

Theses and Dissertations

A rigorous first order shear deformation theory (FSDT) is employed along with modified ABD parameters to analyze static and free vibration behavior of generally laminated beams and shafts. Different approaches for calculating composite beam stiffness parameters have been considered and the most accurate one that accounts for material couplings have been used to analyze static and free vibration behaviors of straight beams with different laminates and boundary conditions. In order to analyze curved beams, the term (1+z/R) is exactly integrated into ABD parameters formulation and an equivalent modulus of elasticity is used instead of traditional stiffness terms to account for …


Activated Sludge As Renewable Fuels And Oleochemicals Feedstock, Emmanuel Durante Revellame Dec 2011

Activated Sludge As Renewable Fuels And Oleochemicals Feedstock, Emmanuel Durante Revellame

Theses and Dissertations

The utilization of activated sludge as feedstock for biofuel and oleochemical production was investigated. Initial studies included optimization of biodiesel production from this feedstock through in situ transesterification. Results of these studies indicated that activated sludge biodiesel is not economically viable. This was primarily due to relatively low yields and the high economics of feedstock dewatering. Strategies to increase biofuel yield from activated sludge were then evaluated. Bacterial species present in activated sludge are known to produce a wide variety of lipidic compounds as carbon and energy storage material and as components of their cellular structures. In addition to lipidic …


Industrial Timberland Transactions In The United States: Firm Financial Performance, Timber Supply, And Welfare Implications, Mohammad Mahfuzur Rahman Dec 2011

Industrial Timberland Transactions In The United States: Firm Financial Performance, Timber Supply, And Welfare Implications, Mohammad Mahfuzur Rahman

Theses and Dissertations

In the last two decades, many firms in the U.S. forest products industry have either divested their timberlands or converted their corporate structures from C corporations to real estate investment trusts (REITs). This study hypothesizes that this large-scale timberland ownership change affects the financial performance of firms involved in divestitures and on timber supply and, as a result, the economic surplus of producers and consumers in the U.S. timber markets. These issues have not been adequately addressed in existing literature. Event analysis and equilibrium displacement models were employed to address firm financial performance in the capital markets and welfare implications …


In-Situ Catalytic Upgrading Of Pyrolysis Vapor, Vamshi Krishna Guda Dec 2011

In-Situ Catalytic Upgrading Of Pyrolysis Vapor, Vamshi Krishna Guda

Theses and Dissertations

The rising fuel prices, environmental concerns over the emission of greenhouse gases, and the limited availability of fossil fuels led to the current focus on developing alternative fuel sources that are sustainable and environmentally benign. Lignocellulosic biomass, due to its high carbon value, abundance and for being greenhouse gas neutral, is a promising alternative energy resource. Fast pyrolysis of lignocellulosic biomass produces high energy density liquid fuel, called bio-oil, which has the potential as transportation fuel. But, crude bio-oils are chemically complex liquids with high oxygen contents (40 % oxygen content), high viscosity, low pH, low thermal stability, and poor …

Center for Translational Medicine Faculty Papers

RATIONALE: Recent work in animal models and humans has demonstrated the presence of organ-specific progenitor cells required for the regenerative capacity of the adult heart. In response to tissue injury, progenitor cells differentiate into specialized cells, while their numbers are maintained through mechanisms of self-renewal. The molecular cues that dictate the self-renewal of adult progenitor cells in the heart, however, remain unclear.

OBJECTIVE: We investigate the role of canonical Wnt signaling on adult cardiac side population (CSP) cells under physiological and disease conditions.

METHODS AND RESULTS: CSP cells isolated from C57BL/6J mice were used to study the effects of canonical …


Geochemical Analysis Of Ancient Activities At Two Plazas In Cobá, Mexico, Eric G. Coronel Dec 2011

Geochemical Analysis Of Ancient Activities At Two Plazas In Cobá, Mexico, Eric G. Coronel

Theses and Dissertations

Two plazas at Cobá, Mexico, may have been the place of market activity during the classic Maya period. The intense decomposition in the warm, moist soils of the Yucatan Peninsula precludes the identification of organic artifacts in archaeological contexts, but phosphorus and trace elements accumulation in soils may provide evidence of marketing activities. The spatial patterns of P and trace element concentrations were used to elucidate the types of ancient Maya activities that took place in those plazas. Phosphorus concentrations are highly correlated (p-value <0.01) with Fe, Mn, and Zn levels in both Plaza B and D. Although the soil geochemistry of Plaza B does not show a marketplace pattern in comparison with previous studies, the elemental concentrations and distributions within Plaza D join other lines of evidence to support the premise that marketplace activities took place at that location. Soil samples were analyzed using DTPA extraction, Mehlich II, Olsen, and Portable X-Ray Fluorescence (PXRF). Experiments were performed to study the suitability of PXRF for field studies. Aspects that were studied include granule size, soil moisture content, protective plastic films that could interfere with the X-Ray signal when placing the samples on top of the analyzer, and a comparison of certified soil standards to the PXRF elemental concentration readings. The results suggest that a field laboratory could be set up to air-dry and sieve soil samples to a minimum mesh size of #10 (> 2 mm).


Neuromechanical Alterations Due To Induced Knee Pain And Effusion During Functional Movements, Jihong Park Dec 2011

Neuromechanical Alterations Due To Induced Knee Pain And Effusion During Functional Movements, Jihong Park

Theses and Dissertations

Purpose: Examine neuromechanical alterations due to isolated and/or combined knee pain and effusion in functional movements. Methods: A 4X3 randomised controlled laboratory study with repeated measures was used. Nineteen, healthy volunteers (age: 22.4 ± 2.4 years) underwent four different treatments (control, effusion, pain, and pain/effusion) with a week wash out period. Ten near-infrared cameras with 43 reflective markers, 12 surface EMG electrodes, and two ground-embedded force platforms were used to record neuromechanical changes during functional movements (walking and drop landing). To induce pain, 5% sodium chloride (1 ml) was injected into the infrapatellar fat pad. To induce effusion, 0.9% sodium …


Functional Characterization Of The Ocfc Gene And Optimization Of Medium Components And Culture Condition For Occidiofungin Production By Burkholderia Contaminans Strain Ms14, Kuan-Chih Chen Dec 2011

Functional Characterization Of The Ocfc Gene And Optimization Of Medium Components And Culture Condition For Occidiofungin Production By Burkholderia Contaminans Strain Ms14, Kuan-Chih Chen

Theses and Dissertations

he 56-kb ocfC gene cluster is required for occidiofungin production by Burkholderia contaminans strain MS14. However, the function of the ocfC gene remains unknown. Sequence analysis showed the putative protein encoded by ocfC shares significant identities to glycosyltransferase. Plate bioassays showed that occidiofungin production by the ocfC mutant (ocfC::nptII) was significantly reduced as compared with strain MS14. The occidiofungin produced by the ocfC mutant is xyloseree, which suggests the ocfC gene encodes a xylosyltransferase to add a xylose to the peptide backbone. Single variant optimization of culture condition and medium compositions was also performed in this study. The results indicated …


Studies On Hexahapto-Dibenzo[A,E]Cyclooctatetraene Complexes Of Chromiumtricarbonyl And Cationic Manganesetricarbonyl, Nilantha Bandara Dec 2011

Studies On Hexahapto-Dibenzo[A,E]Cyclooctatetraene Complexes Of Chromiumtricarbonyl And Cationic Manganesetricarbonyl, Nilantha Bandara

Theses and Dissertations

Mono- and dinuclear chromiumtricarbonyl and manganesetricarbonyl complexes of dibenzo[a,e]cyclooctatetraene (DBCOT) were synthesized and characterized. In the bis(chromiumtricarbonyl)DBCOT synthesis, the main product was the syn,anti isomer where the two Cr(CO)3 moieties coordinate to opposite faces of the DBCOT backbone. This complex exhibits three dynamic processes in solution. A ring inversion of the organic skeleton occurs while the two chromiumtricarbonyl moieties undergo tripod rotation. This is the first study where eight-membered ring inversion is studied for a pi-coordinated metallic system. The rate of inversion at various temperatures was determined by 1H NMR line shape analysis at two different field strengths (300 and …

Investigating How Equating Guidelines For Screening And Selecting Common Items Apply When Creating Vertically Scaled Elementary Mathematics Tests, Maria Assunta Hardy Dec 2011

Investigating How Equating Guidelines For Screening And Selecting Common Items Apply When Creating Vertically Scaled Elementary Mathematics Tests, Maria Assunta Hardy

Theses and Dissertations

Guidelines to screen and select common items for vertical scaling have been adopted from equating. Differences between vertical scaling and equating suggest that these guidelines may not apply to vertical scaling in the same way that they apply to equating. For example, in equating the examinee groups are assumed to be randomly equivalent, but in vertical scaling the examinee groups are assumed to possess different levels of proficiency. Equating studies that examined the characteristics of the common-item set stress the importance of careful item selection, particularly when groups differ in ability level. Since in vertical scaling cross-level ability differences are …


The Legacy Of Cotton: A Geographical Perspective On The Influence Of Traditionalist Politics In Mississippi, William Edward Stephen Cottrell Dec 2011

The Legacy Of Cotton: A Geographical Perspective On The Influence Of Traditionalist Politics In Mississippi, William Edward Stephen Cottrell

Theses and Dissertations

It was hypothesized that the socialspatial dialectic (location, education, politics and race) contributes to Mississippi’s low livability ranking. Regression models were employed using race, student funding rates, high school graduation rates, property tax, and voter turnout in the 82 counties as variables. The research found evidence that Blacks have lower graduation rates than Whites and property tax has a significant effect on voter participation at the gamma = .001 level. Social capital disadvantage seems to reside within both races with voter participation, property tax rates, and school funding being more pronounced with Whites. Results suggest that political capital should not …

A Conceptual Framework For Student Understanding Of Logarithms, Heather Rebecca Ambler Williams Dec 2011

A Conceptual Framework For Student Understanding Of Logarithms, Heather Rebecca Ambler Williams

Theses and Dissertations

In the past, frameworks for what it means for students to understand elementary mathematical concepts like addition have been well-researched. These frameworks are useful for identifying what students must understand to have a good grasp of the concept. Few such research-based frameworks exist for secondary mathematical topics. The intent of this study was to create such a framework for what it means for students to understand logarithms, a topic that has been under-researched up to this point. Four task-based interviews were conducted with each of four different preservice secondary mathematics teachers in order to test a preliminary framework I had …


Seasonal Habitat Selection By Greater Sage Grouse In Strawberry Valley Utah, Riley D. Peck Dec 2011

Seasonal Habitat Selection By Greater Sage Grouse In Strawberry Valley Utah, Riley D. Peck

Theses and Dissertations

This study examined winter habitat use and nesting ecology of greater sage grouse (Centrocercus urophasianus) in Strawberry Valley (SV), Utah located in the north-central part of the state. We monitored sage grouse with the aid of radio telemetry throughout the year, but specifically used information from the winter and nesting periods for this study. Our study provided evidence that sage grouse show fidelity to nesting areas in subsequent years regardless of nest success. We found only 57% of our nests located within the 3 km distance from an active lek typically used to delineate critical nesting habitat. We …

Biophotonic Imaging As A Novel Approach To Study Infectious Diseases In The Bovine, Jaime E. Curbelo Rodríguez Dec 2011

Biophotonic Imaging As A Novel Approach To Study Infectious Diseases In The Bovine, Jaime E. Curbelo Rodríguez

Theses and Dissertations

Conventional bacteriological methods to establish bacterial burden and distribution in infected tissues in vivo animal models typically require extensive bacteriological procedures and therefore are time consuming. An alternative approach has been suggested to use optical markers, such as luciferases, to labeled pathogens and monitor their progress and distribution in real time. The objective of the work presented in this document was to validate the use of Biophotonic Imaging (BI) through in vitro studies as a first step toward the development of in vivo models to study infectious disease in the bovine. For example, the feasibility of detecting bioluminescent Escherichia coli …
