Electrodeless Electro Hydrodynamic Printing Of Personalized Drug Dosages, Ezinwa Okeoma Elele

Dissertations

There is compelling evidence that variability in drug efficacy in individuals depends on their genetic fingerprints. These observations have given rise to the concept of personalized therapy whose ultimate goal is to develop medicinal agents designed for each niche of the population and individual patients according to their genetic background. The drawback in current pharmaceutical technologies is that most processes are designed to target large population and are unable to meet the demand of small-scale manufacturing of tailored therapeutics with diverse range of physical properties. One of the major challenges lie in developing efficient and cost effective methods of manufacturing …

Magnetic Seeding Aggregation To Enhance The Removal Efficiency Of Tio2 Nanoparticles From Water, Ashish Dhananjay Borgaonkar

Dissertations

Engineered nanoparticles, such as titanium dioxide (TiO₂), are important building blocks for the evolution of nanotechnology in industries and commercial products. Ever so increasing use of the engineered nanoparticles is bound to result in a substantial fraction of these nanoparticles ending up in wastewater; or surface water and groundwater, which are sources of intake for drinking water treatment. Removal of these engineered nanoparticles in wastewater and drinking water treatment processes is a very important step towards the protection of environmental and public health as well as protecting water treatment units from fouling and other issues.

Analysis Of Mueller Matrices Of Metamaterials And Multiferroics, Paul D. Rogers

Dissertations

The optical spectra of complex materials such as magnetic-dielectric media, magnetoelectric and multiferroic crystals, materials with intrinsic chirality, and metamaterials are studied. These media are important both for: (i) their interesting optical effects, such as Negative Index of Refraction (NIR) and impedance matching; and (ii) possible device applications such as switching devices and anti-reflection coatings. Proper characterization of complex materials requires advanced spectroscopic approaches and the development of theoretical models for data analysis. Berreman’s 4´4 matrix formalism is used to derive forward models for the optical spectra of Reflectivity, Transmission, Rotating Analyzer Ellipsometry (RAE), and Mueller Matrices (MM). The forward …

Asymptotic And Numerical Analysis Of Time-Dependent Wave Propagation In Dispersive Dielectric Media That Exhibit Fractional Relaxation, Matthew Frank Causley

Dissertations

This dissertation addresses electromagnetic pulse propagation through anomalously dispersive dielectric media. The Havriliak-Negami (H-N) and Cole-Cole (C-C) models capture the non-exponential nature of such dielectric relaxation phenomena, which is manifest in a variety of dispersive dielectric media. In the C-C model, the dielectric polarization is coupled to the time-dependent Maxwell's equations by a fractional differential equation involving the electric field. In the H-N case, a more general pseudo-fractional differential operator describes the polarization.

The development and analysis of a robust method for implementing such models is presented, with an emphasis on algorithmic efficiency. Separate numerical schemes are presented for C-C …

Numerical And Asymptotic Modeling Of Evolving Nonlinear Ocean Surface Wave Fields, Matt Malej

Dissertations

The main focus of this dissertation is the asymptotic and numerical modeling of nonlinear ocean surface wave fields. In particular, a development of an accurate numerical model for the evolution of nonlinear ocean waves, including extreme waves known as Rogue/Freak waves. Due to their elusive and destructive nature, the media often portrays Rogue waves as unimaginatively huge and unpredictable monsters of the sea. To address these concerns, derivations of asymptotically reduced models, based on the small wave steepness assumption, are presented and their corresponding numerical simulations via a Fourier pseudo-spectral method are discussed. The simulations are initialized with a well-known …

Transcriptional Regulation Of Nitrogenase And Identification Of A Fructose Transport System In Anabaena Variabilis, Justin Lynn Ungerer

Dissertations

Little is known about the regulation of nitrogenase genes in cyanobacteria. Transcription of the nifH1 and vnfH genes, encoding dinitrogenase reductases for the heterocyst-specific Mo-nitrogenase and the alternative V-nitrogenase, respectively, was studied using a lacZ reporter. Two promoters were found to be responsible for expression of nifHDK; a weak promoter within nifU1 and a strong promoter upstream of nifB (the nifB1 promoter). The region immediately upstream of vnfH did not drive expression of lacZ, however the region that included the promoter for the upstream gene, ava4055 did. Characterization of the previously reported nifH1 and vnfH transcriptional start sites by 5' …

Race And Justice In Mississippi's Central Piney Woods, 1940-2010, Patricia Michelle Buzard-Boyett

Dissertations

“Race and Justice in Mississippi’s Central Piney Woods, 1940-2010,” examines the black freedom struggle in Jones and Forrest counties. The writer concludes that more than any other region of Mississippi, the Central Piney Woods became the pivotal theater in the war for racial justice because the intensity of its racial oppression combined with its unparalleled suffrage campaign, and watershed street protests forced a federal alliance, instigated landmark court rulings, and generated black political victories that lay the foundations for a more equitable racial order. To obtain a broader perspective on the forces that transformed racial justice over time, this community …

"Reading" The Apprentice: Commerce, Culture, And The Manufacturing Of Reality, Sharon Simpson Terrell

Dissertations

This study examines the six original seasons of the reality television series The Apprentice as a postmodern, cultural artifact. Grounded in Burke’s (1967) “literature as equipment for living,” and Brummett’s (1984) consideration that televised content constitutes literature, the theory of “televised discourse as equipment for living” provided the guide to examine the series. Hall’s (1980) “reading against the grain” oppositional reading technique was utilized to interrogate both the manifest and latent content. The content of the series may indeed provide the audience with a guide to ideological beliefs of both commerce and culture, thereby creating a manufactured reality for its …

Full Court Press: How Mississippi Newspapers Helped Keep State College Basketball Segregated, 1955-1973, Jason Ashley Peterson

Dissertations

During the civil rights era, Mississippi was cloaked in the hateful embrace of the Closed Society, historian James Silver’s description of the white caste systems that used State’s Rights to enforce segregation and promote the subservient treatment of blacks. Surprisingly, challenges from Mississippi’s college basketball courts brought into question the validity of the Closed Society and its unwritten law, a gentleman’s agreement that prevented college teams in the Magnolia State from playing against integrated foes. Led by Mississippi State University’s (MSU) basketball team, which won four Southeastern Conference championships in a five-year span, the newspapers in Mississippi often debated the …
