Puritan hypocrisy and conservative Catholicity : how Roman Catholic clergy in the border states interpreted the U.S. Civil War.

This thesis analyzes how Roman Catholic clergy in the Border States—Missouri, Kentucky, and Maryland—interpreted the United States Civil War. Overall, it argues that prelates and priests from the region viewed the war through a religious lens informed by their Catholic worldview. Influenced by their experiences with anti-Catholicism and nativism as well as the arguments of the Catholic apologist movement, the clergy interpreted the war as a product of the ill-effects of Protestantism in the country. In response, the clergy argued that if more Americans had practiced Catholicism then the war could and would have been avoided. Furthermore, this thesis illustrates how the interconnectedness of the anti-Catholic and antislavery movements shaped the clergy’s interpretations of the war and the political parties of the era. By analyzing how the clergy responded to the election of 1860, the secession crisis, the debate over slavery, and civil liberties disputes during the war, this thesis underscores the clergy’s belief that Protestantism created fanatical leaders, sectional division, and national instability, while Catholicism preserved law, order, and morality in society

The Amazon Kindle: Uses in Higher Education

The Environmental Impacts of Trade Liberalization: A Quantitative Analysis for the United States Using TEAM

A highly disaggregated emissions factor model is presented. The model generates changes in emissions and resource use by state and 6-digit NAICS sector. Removal of all U.S. import restrictions is examined. Results for agriculture show that composition effects explain highly varied regional patterns of emission changes. Scale effects are also important for expanding sectors. Quantitative assessments such as this may prove useful in conducting full environmental reviews of U.S. trade agreements consistent with Executive Order 13141 and the Free Trade Act of 2002.trade, emissions, input-output, residuals, International Relations/Trade,

Development of Novel Material Design Strategies for High-Efficiency and Tunable Photoluminescence Properties

New developments in the understanding of structural-optical property relationships of optoelectronic materials have led to rapid growth in energy-efficient solid-state lighting technologies. These improvements in the field of inorganic materials chemistry have led to new products, such as light-emitting diodes (LEDs) for residential lighting, scintillators for radiation detection, and luminescent inks for anti-counterfeiting applications. The emergence of lead halide perovskites has led to a paradigm shift in this area, with many groups around the globe working on both fundamental properties and practical applications of this diverse family. An unexplored alternative to the toxic nature of lead halides is the recently discovered families of earth-abundant and non-toxic copper(I) and silver halides. The structural-optical property relationships and physical properties of these new materials must be elucidated to continue development. This work focuses on understanding the optoelectronic properties of copper(I) and silver halides. The work also explores the strategy of utilizing organic cations as the source of emission, as opposed to more popular reliance on the metal halide polyhedra. To better understand the history and fundamental science, the work begins with an introduction to down-converting metal halides in chapter 1. The information presented in the first chapter directly applies to the following chapter, as chapter 2 continues by investigating A2CuX3 (A= K, Rb and X= Cl, Br), a family of bright blue photoluminescent compounds with up to unity absolute photoluminescent quantum yield. A series of optical measurements were completed in order to thoroughly examine the effects of elemental substitution. The optical measurements were also supported with additional chemical purity and environmental stability test. The emission mechanism in these materials is established through a combination of spectroscopic and computational studies. While the all-inorganic copper(I) halides answered some questions, many more were asked upon completion of the work. To further explore the impact of substituting the metal center, chapter 3 dives into the analogous silver halides in hopes of better understanding the varying emission mechanisms that can exist in these systems. These compounds display tunable, white emission, in stark contrast to their copper(I) counterparts. A broader elemental substitution study was conducted to understand the role of vacancies in the system. The work progressed beyond fundamental material design and continued into preliminary application research. While extensive investigations of crystal and electronic structures and optical properties of all-inorganic group 11 metal halides have been conducted, a vast family of hybrid Cu(I) and Ag(I) materials remains unexplored. The last research component, chapter 4, changes directions away from metal-derived emission and explores the area of organic-derived emission. Although many organic compounds are known to be efficient light emitters, they are often unstable for practical application considerations. This work evaluates a novel method to stabilize and improve the photoluminescent emission while maintaining the same emission profile. The work opens the door to more hybrid organic-inorganic emitters. To tie everything together, chapter 5 concludes the work and discusses future directions

The hydrodynamic design and analysis of an RP-1 pump for a liquid rocket engine.

Master of Science in Mechanical Engineering. University of KwaZulu-Natal. Durban, 2018.South Africa has a fledgling satellite industry but lacks the ability to launch spacecraft into low Earth orbit. As a result, the University of KwaZulu-Natal’s (UKZN’s) Aerospace Systems Research Group (ASReG) began the development of the South African First Integrated Rocket Engine (SAFFIRE). SAFFIRE aims to be a versatile, small scale, liquid rocket engine capable of being clustered for use on small-satellite (‘small-sat’) launch vehicles. The propellants for the proposed engine are Rocket Propellant-1 (RP-1) and liquid oxygen (LOX), which are fed into the combustion chamber via the injector. The uniqueness of SAFFIRE lies in the use of electrically driven pumps (‘electropumps’) as opposed to the conventional turbopump design. The electropump system has the fuel and oxidiser pumps independently housed and driven by brushless DC motors, which draw power from a lithium-polymer battery pack. A hypothetical launch vehicle was proposed to validate design specifications for the SAFFIRE engine, from which the hydrodynamic requirements of the electropump system were obtained. A meanline design algorithm was developed, using conventional design methods for centrifugal pumps. The algorithm was constructed to simultaneously meet the hydrodynamic system requirements of the engine, minimize the potential of cavitation at the fuel pump inlet and maximize the operational speed to minimize the overall pump weight. The hydrodynamic requirements of the system result in a low specific speed design, thus placing the pump in the region between full emission centrifugal pumps and positive displacement pumps. The low specific speed presented unique problems, not commonly encountered via the conventional pump design method, such as excessively small blade exit widths that are sensitive to dimensional variations. The Barske pump was investigated as a potential solution; it is a partial emission pump with the meanline design being governed by vortex theory. A comparative analysis between the conventional and Barske design was done using computational fluid dynamic techniques. The final hydrodynamic design is a hybrid between a Barske impeller and a scroll collection volute, which is typically found on a full emission pump. An investigation was done to determine an appropriate solution for mitigating the cavitation. It was found that the initial 3 bar tank pressure, suggested by literature, is applicable for an equivalent engine utilizing a turbopump system. The optimal tank pressure for the electropump system was found to be 9 bar. This increased available pressure head at the inlet of the pump eliminated any form of cavitation. The hybrid pump delivers 62.12 bar of pressure at a mass flow rate of 2.75 kg/s with a 62.12 % efficiency
