Computation Of Hypersonic Flows With Lateral Jets Using K-Ω Turbulence Model, Spatika Dasharati Iyengar

Doctoral Dissertations and Master's Theses

Thermal Protection systems (TPS) are used as shields in space vehicles which encounter high heat and temperatures at the reentry altitudes. Among them, the cooling techniques and the ablative coatings are most popular. However, they have their own weight limitations. In the recent decade, another classification of TPS called the Non-Ablative Thermal Protection systems (NaTPS) have gained significance. The spike-lateral jet method is an NaTPS concept proposed for drag and heat flux reduction in hypersonic nose cones. Numerical simulations are conducted to analyze the effectiveness of spike-lateral jet concept at re-entry altitudes. The spike attached to the hemispherical nose has …

Situating Care In Mainstream Health Economics: An Ethical Dilemma?, John B. Davis, Robert Mcmaster

Economics Faculty Research and Publications

Standard health economics concentrates on the provision of care by medical professionals. Yet ‘care’ receives scant analysis; it is portrayed as a spillover effect or externality in the form of interdependent utility functions. In this context care can only be conceived as either acts of altruism or as social capital. Both conceptions are subject to considerable problems stemming from mainstream health economics’ reliance on a reductionist social model built around instrumental rationality and consequentialism. Subsequently, this implies a disregard for moral rules and duties and the compassionate aspects of behaviour. Care as an externality is a second-order concern relative to …

Bilateral Tax Treaties And Us Foreign Direct Investment Financing Modes, Joseph P. Daniels, Patrick O'Brien, Marc Von Der Ruhr

Economics Faculty Research and Publications

Though it is often claimed that bilateral tax treaties promote foreign direct investment (FDI), previous empirical studies do not support this view. Indeed, the literature provides mixed results where bilateral tax treaties have a positive impact on FDI flows in some studies and a negative impact in other studies. Using US FDI outflows disaggregated into financing modes, equity capital, reinvested earnings, and inter-company debt, we estimate fixed-effects quantile regression models that include controls for new tax treaties, existing treaties (in place prior to the start of the sample period), and the total number of tax treaties a host country has …

Characterization Of Sbip68: A Putative Tobacco Glucosyltransferase Protein And Its Role In Plant Defense Mechanisms, Abdulkareem O. Odesina

Electronic Theses and Dissertations

Plant secondary metabolites are essential for normal growth and development in plants ultimately affecting crop yield. They play roles ranging from appearance of the plants to defending against pathogen attack and herbivory. They have been used by humans for medicinal and recreational purposes amongst others. Glycosyltransferases catalyze the transfer of sugars from donor substrates to acceptors. Glucosyltransferases are a specific type of glycosyltransferases known to transfer glucose molecules from a glucose donor to a glucose acceptor (aglycone) producing the corresponding glucose secondary metabolite or glycone, in this case glucosides. It was hypothesized that SBIP68, a tobacco putative glucosyltransferase-like protein glucosylated …

Navigating Gender Inequality In Musical Subgenres, Adria Ryan Mclaughlin

Electronic Theses and Dissertations

This study looks at female musicians performing in subcultural rock genres commonly considered non-gender-conforming, such as punk rock, heavy metal, noise, and experimental. Twenty-four interviews were conducted with female musicians who reflected on their experiences as musicians. Themes emerged on women’s patterns of entry into music, barriers they negotiated while playing, and forces that may push them out of the music scene. Once women gained a musician identity, their gender functioned as a master status. They negotiated sexism when people questioned their abilities, assumed men played better, expected them to fail, held them to conventional gender roles, and sexually objectified …

Effects Of Complex Formation Of Dna With Positively Charged Polyamines And Polypeptides On The Products Of Oxidative Damage To Dna 2-Deoxyribose By Hydroxyl Radicals, Modeste N. Tegomoh

Electronic Theses and Dissertations

It is known that histones and other DNA-binding polycations protect DNA from radiation damage mediated by hydroxyl radicals. Until recently, this protection of DNA has mainly been attributed to compaction and aggregation. It was hypothesized that chemical repair of DNA sugar radicals by donation of hydrogen atom from polycations also significantly contributes to DNA protection. To test this hypothesis, the relative yields of low-molecular weight characteristic products of oxidation of DNA sugar were compared in X-irradiated samples of naked DNA and DNA complexes with a number of polycations by using an HPLC-based method of DNA damage product quantification. The variation …

If I Had A Hammer: American Folk Music And The Radical Left, Sarah C. Kerley

Electronic Theses and Dissertations

Folk music is one of the most popular forms of music today; artists such as Mumford and Sons and the Carolina Chocolate Drops are giving new life to an age-old music. It was not until the 1950s that new popular interest in folk music began. Earlier, folk music was used by leftist organizations as a means to reach the masses. It assumed because of this history that many folk artists are sympathetic to the Left. By looking at the years from 1905-1975 with the end of the Vietnam War, this study hopes to present the notion that even though these …

A Physiologically-Based Pharmacokinetic Model For Vancomycin, Rebekah White

Undergraduate Honors Theses

Vancomycin is an antibiotic used for the treatment of systemic infections. It is given

intravenously usually every twelve or twenty-four hours. This particular drug has a

medium level of boundedness, with approximately fty percent of the drug being free

and thus physiologically eective. A physiologically-based pharmacokinetic (PBPK)

model was used to better understand the absorption, distribution, and elimination of

the drug. Using optimal parameters, the model could be used in the future to test

how various factors, such as BMI or excretion levels, might aect the concentration

of the antibiotic.

Innocent Until Proven Guilty: Shakespeare's Use Of Source Material In Three Plays, Alexandria C. Mcqueen

Undergraduate Honors Theses

In my thesis, I discuss and analyze William Shakespeare’s utilization and adaptation of source texts within three of his dramas: Henry IV, Part I, a history; Twelfth Night, a comedy; and Julius Caesar, a tragedy. By comparing Shakespeare’s adaption of sources to the contemporary United Kingdom intellectual property policies, it becomes possible for me to determine whether Shakespeare’s extensive and popular dramas would violate modern copyright law.

The first chapter, “Printing and Writing in the Early Modern Period,” discusses the development of proprietary interests among the Elizabethan people. I break down the individual components of the printing process in …
