“Every Good Man Is A Quaker, And That None But Good Men Are Quakers”: Transatlantic Quaker Humanitarians, Disability, And Marketing Enlightened Reform, 1730-1834, Nathaniel Smith Kogan

History Dissertations - Archive

This dissertation explores how Quaker humanitarians in the eighteenth and nineteenth centuries actively absorbed and employed emerging Enlightenment discourses about “disability” and human dependency as a means to build support for, fund, and market their reform activities. Beginning in the eighteenth century in their abolitionist advocacy, Quakers harnessed Enlightenment rhetoric about disability and public displays of aberrant bodies and minds in order to raise attention to the plight of various marginalized groups and also to raise funds to support these causes. This emerging concept of disability, which was very individualized, cohered nicely with Quakers’ central theological tenet of the “Inner …

An Invastigation Of Band-Limited Fluid Damper Configuration Using Lumped Parameter Modeling, Ye Hong Dec 2015

An Invastigation Of Band-Limited Fluid Damper Configuration Using Lumped Parameter Modeling, Ye Hong

Mechanical and Aerospace Engineering Theses - Archive

Vehicle suspension system is one of the key factors related to the vehicle dynamic characteristic. The fine tuning of suspension system between vehicle handling and ride comfort is not only a trade-off between these two aspects, but also, has its impact on vehicle safety and durability. For an optimal damper performance, the damper needs to generate sufficient damping force at maneuvering frequency (< 2 Hz); and it also needs to generate less damping force, which allow spring to filter the high frequency noise (> 2 Hz) generated by vehicle travels along rough road condition at speed. In order to achieve such performance, a lumped parameter model of Band-Limited Damper is proposed. Frequency response of both Conventional Damper and Band-Limited Damper are …

A Model Analysis Of Sand Insertion In Hydraulic Fractures, Ya Hao Dec 2015

A Model Analysis Of Sand Insertion In Hydraulic Fractures, Ya Hao

Mechanical and Aerospace Engineering Theses - Archive

Hydraulic fracturing (fracking) is a well-stimulation technology to create large volume of fracture formation in rocks for gas and/or oil extraction. This technology has been applied to commercially exploit natural gas in unconventional shale reservoirs that contain immense quantity but low density of hydrocarbon sources. The productivity can be largely dependent on the connectivity of fractures that must stay open. However, upon initial hydraulic fracturing, the fractures would be closed due to high hydrostatic pressure deep inside the crust. Sand must be pumped into the fractures to keep them open. An in-depth understanding of the sand distribution and its dependence …

Magnetic Field Enhanced Thermal Conductivity Analysis Of Magnetic Nanofluids, Christopher Allen Dec 2015

Magnetic Field Enhanced Thermal Conductivity Analysis Of Magnetic Nanofluids, Christopher Allen

Mechanical and Aerospace Engineering Theses - Archive

The magnetic properties of four water-based nanofluids consisting of Al2O3, CuO, Fe3O4, and SiO2 were exploited to analyze the effect of the application of an external magnetic field on the thermal conductivity of the nanofluid. When the magnetic field is applied, the magnetic dipole moments of the particles align and the particles come in contact with each other and form chains in the direction of the applied magnetic field. When parallel to the direction of heat flow, the magnetic field causes the effective thermal conductivity in the direction of the magnetic field to increase. A higher thermally conductive fluid can …

Influencing Donor Decision-Making: An Examination Of Situational Determinants That Impact Donation, Floyd Kristopher Dec 2015

Influencing Donor Decision-Making: An Examination Of Situational Determinants That Impact Donation, Floyd Kristopher

Marketing Dissertations - Archive

Research around donor decision-making has shown the importance of understanding why donors make decisions. However, much less research exists explaining how donors make decisions. Set against the backdrop of online websites and in the context of donation, this dissertation examines how web characteristics, as situational determinants, influence donor decisions. Situational determinants are influences that arise because of a specific situation where a consumer is using the product or brand; these are instances that extend beyond the basic tendencies or traits of the consumer (Belk 1974). This could be a behavioral setting, a space, or a time (Belk 1974); other situational …

Material Changes Of Bone Following Ishcemia Of The Immature Femoral Head, Olumide O. Aruwajoye

Material Science and Engineering Dissertations - Archive

Legg-Calvé-Perthes disease (LCPD) is a childhood hip disorder resulting from the loss of blood flow to the femoral head. In severe cases of the disease, the femoral head can develop a flattening deformity; additionally, if the disease is diagnosed at a later stage, it leaves most patients to develop early osteoarthritis of the hip. Due to a lack of pathological specimen from patients, an experimental piglet model of femoral head ischemia was developed. The model closely follows the radiographic changes seen in LCPD patients, where there is subchondral fracture, resorption, and a flattening deformity of the femoral head. After ischemia, …

Merging Radar-Only Qpe And Rain Gauge Data Via Conditional Bias-Penalized Optimal Estimation, Beomgeun Kim Dec 2015

Merging Radar-Only Qpe And Rain Gauge Data Via Conditional Bias-Penalized Optimal Estimation, Beomgeun Kim

Civil Engineering Theses - Archive

A new technique for merging radar precipitation estimates and rain gauge data is developed and evaluated to improve multisensor quantitative precipitation estimation (QPE). Various types of linear and nonlinear techniques have been used to combine rain gauge and radar data. Linear cokriging and its variants, for example, may be considered as the best linear unbiased estimators which minimize the error variance in the unconditional sense. They are, however, subject to conditional biases (CB) that may be unacceptably large for estimation of heavy-to-extreme precipitation. In this work, I develop, apply, and evaluate conditional bias-penalized cokriging (CBPCK) for spatial estimation of precipitation …

Becomes A Woman Best: Female Prophetic Figures In Shakespeare's Plays, Alan Morris Cochrum Dec 2015

Becomes A Woman Best: Female Prophetic Figures In Shakespeare's Plays, Alan Morris Cochrum

English Theses - Archive

This dissertation argues that female characters in Shakespeare’s The Winter’s Tale, Henry VIII, Richard III, Macbeth, and 1 Henry VI function as prophets in the style of the Old Testament. In a culture that venerates Holy Writ but also devalues women, a dramatic exemplar wrapped in the mantle of a biblical prophet becomes a potential model for playgoers as well as an embodied critique. Paulina, Katherine of Aragon, and Margaret of Anjou condemn injustice, uphold the cause of the vulnerable, challenge the abuse of royal and spiritual authority, and frequently echo aspects of biblical figures such as Moses, Isaiah, and …
