Obstructing Authenticity: The Church And Sexuality In Randall Kenan’S A Visitation Of Spirits And Jeanette Winterson’S Oranges Are Not The Only Fruit, Kyesha L. Jennings
Theses
The dominant beliefs of a society determine what it finds acceptable and socially constructed theories generally valorize only heterosexism. Thus, global society has viewed homosexuality as a repudiation of the norm—an aberration, a disease, or a “lifestyle”—all of which carry negative social connotations. While this particularly characterizes churches within the African American community, identical issues occur within other denominations of Christianity. This study will explore literary texts that display how the Christian church, more specifically the Baptist and Pentecostal denominations, obstruct homosexuals’ identity by implementing a limited, rigid morality that rejects all who do not fit within its code, a …

State And Parameter Estimation With A Sequential Monte Carlo Method In A Three Dimensional Transport Model, Tushar Chowhan
Theses
Due to the inherent randomness and heterogeneity of the transport process, macrodispersion, non-fickian motion, and ergodicity, general assumptions of linearity and Gaussian distribution do not hold for the real field. Therefore, a state-space transport model for the non-linear and non-Gaussian system is proposed in this study. In this study, the state variable (concentration vector) and parameter (first-order decay) are updated with the available measurements. The probabilistic state-space formulation and updating of information on receipt of new measurements is formulated in the Bayesian framework. particle filter, a sequential Monte Carlo method, provides a rigorous general framework for dynamic state estimation problems …

Fabrication Of Pd-Cu Membranes By Surfactant Induced Electroless Plating (Siep), Md. Saiful Islam
Fabrication Of Pd-Cu Membranes By Surfactant Induced Electroless Plating (Siep), Md. Saiful Islam
Theses
Pd-Cu composite membranes on microporous stainless steel substrate (MPSS) were fabricated by novel electroless plating (EP process. In conventional Pd-EP process, the oxidation-reduction reactions between Pd-complex and hydrazine result in evolution of NH3 and N2 gas bubbles. When adhering to a substrate surface and in the pores, these gas bubbles can hinder uniform Pd-film deposition, which results in dendrite growth leading to poor film formation. We addressed this problem by introducing cationic surfactant in the electroless plating process known as surfactant induced electroless plating (SIEP). The unique features of this innovation provide control of (1) Pd- and Cudeposition rate, and …

Evaluation Of Rice Extract As A Potential Stabilizer In Plain Yogurt, Sangeetha Nurani Viswanathan
Theses
Quality and consumer acceptability are essential parameters in dairy products The objectives of the present study were to examine the microbiological (viability of L. bulgaricus, S. thermophilus, and bifidobacteria), chemical (pH, titratable acidity, and total solids), and physical(syneresis) qualities of yogurt enriched with rice extract as a stabilizer during 28 days of storage at 4°C. Additionally, viscosity measurements and consumer acceptability were determined for yogurt enriched with rice extract. Results showed that the viability of L. bulgaricus was maintained with the addition of rice extract. Population of Streptococcus thermophilus and bifidobacteria decreased significantly (p<0.05) in the control sample but the addition of rice extract at 15% concentration supported the viability of bifidobacteria in yogurt over storage. The addition of rice extract did not alter the pH or titratable acidity of yogurt. Viscosity, total solids and syneresis values slightly changed with the addition of rice extract. Yogurt prepared with rice extract ranked higher in terms of texture and appearance by the panelists. Our results indicated that the addition of rice extract could improve the quality characteristics and consumer acceptability of plain yogurt. Hence, rice extract has a promising potential to be used as an alternative stabilizer in dairy products.

Probabilistic Analysis Of Property Uncertainties Using Resin Infusion Flow Modeling And Simulations - Resin Viscosity And Preform Permeability, Henok Shiferaw
Theses
Physics based flow modeling provides an effective way to simulate the resin infusion process in liquid composite molding processes for polymer composite structures. These are effective to provide optimal injection time and locations for given process parameters of resin viscosity and preform permeability prior to resin gelation. However, there could be significant variations in these two parameters during actual manufacturing due to differences in the resin batches, mixes, temperature, ambient conditions for viscosity; in the preform rolls, compaction, etc., for permeability. The influence of uncertainties in these parameters on the resin infusion time is investigated via a probabilistic modeling methodology …
