A Conductor's Guide To Ariel Ramirez's Misa Por La Paz Y La Justicia, Andrew David Alegria

LSU Doctoral Dissertations

The purpose of this monograph is to establish that Ariel Ramírez Misa Por La Paz y La Justicia is a significant choral work of the twentieth century that expresses the idea of peace during a time of disorder. My study will focus mostly on an analysis of the work, but will also provide additional information on the life of the composer. This will afford future conductors a resource on the Mass. My hope is that with this in-depth study of the work, conductors and/or ensembles will be more willing to perform this Mass. The parallels between the historical period in …

Data-Driven Computational Approach To Study Bio-Molecular Interactions, Misagh Naderi

LSU Doctoral Dissertations

Proteins commonly convey their functions in coordination with other proteins, small molecules and/or other biological assemblies such as sugars, lipids, DNA or RNA. Understanding the nature of these interactions is therefore central to improving our knowledge of biological systems. This body of work is a consolidation of three different computational approaches to study bio-molecular interactions: large-scale protein-ligand modeling, fragment-based cheminformatics, and computational analysis of interactions in single proteins.

The first issue that is addressed in this study is the scarcity of atomic crystal structures of protein-drug complexes. In general, a drug molecule’s affinity for multiple protein targets may causes unsolicited …

Paul Hindemith's Cello Concerto (1940): A Short History And An Ongoing Personal Quest Toward Its Comprehension, Mastery, And Performance, Eunbi Kim

LSU Doctoral Dissertations

ABSTRACT

I was introduced Paul Hindemith’s Cello Concerto (1940) in 2015, my first year as a Doctoral Student. Admittedly, this piece was not very attractive to me. However, I tried to embrace this work, and experience it as a new adventure in ear training, technical challenge and style. Several weeks later, after many frustrating hours of practice, I closed this music because so many elements of this composer’s sound were unfamiliar and foreign to me, to which I could not easily relate. Even though I had listened and examined this work for these initial weeks, I felt horribly under-prepared, musically …

© 2018 The Author(s). Background: Since the completion of the human genome project, the diversity of genome sequencing data produced for non-human primates has increased exponentially. Papio baboons are well-established biological models for studying human biology and evolution. Despite substantial interest in the evolution of Papio, the systematics of these species has been widely debated, and the evolutionary history of Papio diversity is not fully understood. Alu elements are primate-specific transposable elements with a well-documented mutation/insertion mechanism and the capacity for resolving controversial phylogenetic relationships. In this study, we conducted a whole genome analysis of Alu insertion polymorphisms unique to …

The objective is to evaluate biomechanical and pathophysiologic events regarding laminitis and synovitis.

MATERIALS AND METHODS-The first study evaluated biomechanical effects of insulin on lamellar strength. For this experiment, lamellar explants were harvested, incubated in media only (serving as a control) or media with a high concentration of insulin for 8 hours. After incubation, structural integrity was evaluated with a mechanical testing device. Data included load to failure (N), stress to failure (MPa), elongation …

Press To Stop, Garrett Duncan Hazelwood

LSU Master's Theses

In the wake of a performance art piece in which the audience kills one of the performers and maims the other, the surviving artist is put on display in art galleries by his family. The public clamors to see him, protests against his exploitation rock the city, and intrigue surrounds his sudden rise to fame. In the end, a religion is founded in his honor and his best friend must make a terrible choice about whether or not to save him.

Resampling Methods And Visualization Tools For Computer Performance Comparisons In The Presence Of Performance Variation, Samuel Oridge Irving

LSU Master's Theses

Performance variability, stemming from non-deterministic hardware and software behaviors or deterministic behaviors such as measurement bias, is a well-known phenomenon of computer systems which increases the difficulty of comparing computer performance metrics and is slated to become even more of a concern as interest in Big Data Analytics increases. Conventional methods use various measures (such as geometric mean) to quantify the performance of different benchmarks to compare computers without considering this variability which may lead to wrong conclusions. In this paper, we propose three resampling methods for performance evaluation and comparison: a randomization test for a general performance comparison between …

Wonder Women: How Race And Gender Influenced News Coverage In The 2017 New Orleans And Atlanta Mayoral Elections, Sirdaria I. Williams

LSU Master's Theses

The few research studies that explore the media’s coverage of female and or minority candidates have primarily been limited to mix gender elections. Not much attention has been given to what coverage of elections featuring all female candidates looks like. Do atypical candidates lead to atypical coverage? To expand this area of research, this study examines local newspaper’s coverage in mayoral runoff elections. This study’s exploration of how the media portrays candidates running in all female races relies on a content analysis of the two cities examined primary newspapers. The findings from this study are varied and complex. The findings …

Entropic Bounds On Two-Way Assisted Secret-Key Agreement Capacities Of Quantum Channels, Noah Anthony Davis

LSU Doctoral Dissertations

In order to efficiently put quantum technologies into action, we must know the characteristics of the underlying quantum systems and effects. An interesting example is the use of the secret-key-agreement capacity of a quantum channel as a guide and measure for the implementation of quantum key distribution (QKD) and distributed quantum computation. We define the communication task of establishing a secret key over a quantum channel subject to an energy constraint on the input state and while allowing for unlimited local operations and classical communication (LOCC) between a sender and receiver. We then use the energy-constrained squashed entanglement to bound …

Characterization Of The Interaction Between R. Conorii And Human Host Vitronectin In Rickettsial Pathogenesis, Abigail Inez Fish

LSU Doctoral Dissertations

Spotted Fever Group Rickettsia are inoculated into the mammalian host during hematophagous arthropod feeding. Once in the bloodstream and during dissemination, the survival of these pathogens is dependent upon their ability to evade innate host defenses until a proper cellular target is reached. The establishment of a successful infection also relies on the ability of the bacteria to attach and invade target cells, as failure to do so results in destruction of the bacterium. Rickettsia conorii expresses an outer membrane protein, Adr1, which binds the multifunctional human glycoprotein, vitronectin, to promote resistance to complement mediated killing. Homologs of Adr1 are …

Feminism And The Black Church: A Qualitative Analysis Of Feminism Among Black Women In A Southern Baptist Church, Brianne Alexandra Painia

LSU Doctoral Dissertations

Black women’s religious faith has been found to be integral to their survival (Harris-Perry 2011) in a world that many times chooses to marginalize them due to a host of factors, including their race, gender, and expressions of sexuality (Collins 1996; Morgan 2000) meaning that for black women religion is more than a simple denominational label (such as Lutheran, Catholic, or Baptist). Black women’s involvement in the Black Church has been covered from a variety of angles with researchers noting the importance of African American women to the success of many black churches (Evans 2001), the benefits such faith practice …

Nutrition Misconceptions And Awareness Among College Students In A University Community, Shervia Singleton Taylor

LSU Doctoral Dissertations

Identification of misconceptions of macronutrients (carbohydrate, protein, and fat ) and awareness of ailments linked to micronutrients (potassium, fiber, Vitamin D. and food label use) based on certain demographics are vital to improving and developing long term health benefits, increasing consumption of fruits and vegetables, and decreasing healthcare cost associated with poor dietary lifestyles among non-major general biology college students at a historically black college and university located in the southern part of the United States. Misconception Identification (all groups) was determined using the pretest and posttest Nutrition Knowledge Test via Qualtrics that included two and three tiered question format …

On Structures Of Large Rooted Graphs, Shilin Wang

LSU Doctoral Dissertations

A rooted graph is a pair (G,R), where G is a graph and R⊆V(G). There are two research topics in this thesis. One is about unavoidable substructures in sufficiently large rooted graphs. The other is about characterizations of rooted graphs excluding specific large graphs.

The first topic of this thesis is motivated by Ramsey Theorem, which states that K_n and ¯(K_n ) are unavoidable induced subgraphs in every sufficiently large graph. It is also motivated by a classical result of Oporowski, Oxley, and Thomas, which determines unavoidable large 3-connected minors. We first determine unavoidable induced subgraphs, and unavoidable subgraphs in …

Development Of A Literary Dispositif: Convening Diasporan, Blues, And Cosmopolitan Lines Of Inquiry To Reveal The Cultural Dialogue Among Giuseppe Ungaretti, Langston Hughes, And Antonio D’Alfonso, Anna Ciamparella

LSU Doctoral Dissertations

This dissertation seeks to create a literary dialogue among the Italian poet Giuseppe Ungaretti, the African American author Langston Hughes, and the Quebecois writer Antonio D’Alfonso. Giuseppe Ungaretti and Langston Hughes were more or less contemporaries. Ungaretti was born in 1888 and Hughes in 1902, and both were active in modernist movements that shaped the literary history of their own countries. D’Alfonso was born in Canada about half a center after Ungaretti and Hughes. Besides significant generational differences, these three authors also underwent personal and intellectual experiences that shaped their writing in seemingly incomparable ways. While a traditional comparative approach …

Considerations On Direct Balancing Of Ultra-High Power Ac Arc Furnaces In Uneasy State, Ikenna Louis Ezeonwumelu

LSU Master's Theses

During the operation of ultra-high-power ac arc furnace the negative effects of unbalance mostly occur in the secondary terminals of the transformer connected to the load. Hence balancing and compensating the furnace at this terminal will not only improve the transformer efficiency but also reduce energy losses that do occur. In this thesis a computer modeling of a reference ac arc furnace in both balanced and unbalanced states were simulated, and the effects of a reactive balancing compensator installed on the secondary side of the furnace transformer was evaluated to see how much delivered energy improvement can be obtained. The …

Cloning, Purification, And Preliminary Dna-Binding And Unfolding Results For The Dna Polymerase I From The Psychrophile Psychromonas Ingrahamii, John Tod Baker

LSU Master's Theses

Psychromonas ingrahamii is a psychrophilic bacterium that lives in Arctic polar sea ice and grows at a temperature range of -12 to 10º C. This bacterium resides within veins inside the ice where the salinity is high, resulting in a freezing point depression and liquid water. The large fragment of DNA polymerase I from Psychromonas ingrahamii, called Klenpin, has been cloned, expressed, and purified in our laboratory. Although enzyme kinetic studies have been performed on a few psychrophilic enzymes, the thermodynamics of ligand binding and of protein stability have not been well studied for this class of extremophilic proteins. …

Analysis Of Submerged Aquatic Vegetation Resources Across The Northern Gulf Of Mexico: Communities And Biomass, Eva R. Hillmann

LSU Doctoral Dissertations

Submerged aquatic vegetation (SAV) provides many critical ecosystem services, yet we lack basic information on SAV assemblages, biomass and diversity across expansive coasts such as the northern Gulf of Mexico (nGoM). This research investigated SAV along the nGoM from 2013-2015 examining (1) inter-annual variation in SAV assemblages and biomass across salinity zones and gulf coast eco-regions (Texas Mid-Coast, Texas/LA Chenier Plain, Louisiana Delta, MS/AL), (2) intra-annual variation in SAV assemblages and biomass across salinity zones, (3) response of two species, Ruppia maritima and Myriophyllum spicatum, to salinity and light regimes, and (4) estimated organic carbon stock and storage of …

LSU Master's Theses

In The Ghost You Deserve, a young entrepreneur has developed the ability to artificially replicate deceased family members using the memories of their living loved ones. Spectral resurrections, as they’re called, have become status symbols among the upper middle class. These chapters follow Raj, the brilliant but flawed creator of BioSpec, juxtaposing the story of his college relationship with a young woman named Amada in 2005 with glimpses of him in the present, where he keeps a carefully constructed representation of his ex-girlfriend in a glass mansion by the sea. The novel examines campus relationship abuse and the unintended …

Scattered Feathers, Dason Sebastian Pettit

LSU Master's Theses

Scattered Feathers is the story of a ghost that lives in the imagination now: the ivory-billed woodpecker. Those that know this bird call it the God Bird or Grail Bird because of its mythic stature. This thesis is also a story about the loss and obsession that can fuel human pursuits. It is a study in observation and subsequent mythmaking, an examination of extinction and preservation. Perhaps most of all it is a chronicle of entropy and the cyclical nature of our existence. The visual work herein examines the mythos of the ivory-billed woodpecker, its once pristine environment and the …

Whole Tart Cherry Improves Disease Activity Index In Rat Model Of Dextran Sulfate Solution – Induced Ulcerative Colitis By Downregulating The Janus 1 And Janus 3 Kinases And Tnf - Alpha, Johana Alexandra Coronel

LSU Master's Theses

Ulcerative colitis (UC) is a disabling inflammatory bowel disease. UC is characterized by chronic, relapsing inflammation of the colon and rectum. Current treatments such as monoclonal antibodies against TNF-α, IL-6, IL-12/p40, adhesion molecules, Janus kinases (JAK) inhibitors have side effects or lose their effects over time. Alternative approaches with fewer side effects for patients are needed. Montmorency tart cherries (Prunus cerasus) are a good source of anti-inflammatory flavonoids. We hypothesized that regular consumption whole tart cherry (TC) standardized to its major anthocyanin content, namely cyanidin-3-glucosyl-rutinoside, would be effective in reducing inflammation in UC. The aim of this research was to …

Advanced Modeling, Design, And Control Of Ac-Dc Microgrids, Hossein Saberi Khorzoughi

LSU Doctoral Dissertations

An interconnected dc grid that comprises resistive and constant-power loads (CPLs) that is fed by Photovoltaic (PV) units is studied first. All the sources and CPLs are connected to the grid via dc-dc buck converters. Nonlinear behavior of PV units in addition to the effect of the negative-resistance CPLs can destabilize the dc grid. A decentralized nonlinear model and control are proposed where an adaptive output-feedback controller is employed to stabilize the dc grid with assured stability through Lyapunov stability method while each converter employs only local measurements. Adaptive Neural Networks (NNs) are utilized to overcome the unknown dynamics of …

The Effects Of Metal Speciation, Content And Cluster Size In Fly Ash On Pcdd/F Formation, Xia Guan

LSU Doctoral Dissertations

Transition metal oxides present in waste incineration systems have the ability to catalyze the formation of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) through surface mediated condensation of organic dioxin precursors. Current studies have concentrated on the catalytic effects of individual transition metal oxides, while the complex composition of fly ash introduces the possibility of synergistic or antagonistic effects between multiple, catalytically active components. In addition, there is at present hardly a quantitative link between fly ash physical properties/chemical reactivity and PCDD/Fs yield.

We have tested fly ash surrogates containing different ratios of iron (III) oxide and copper (II) oxide …

A Rhythmic Transcription And Spectral Analysis Of Luciano Berio's Thema (Omaggio A Joyce), Christopher C. Mccardle

LSU Doctoral Dissertations

Thema (Omaggio A Joyce), composed by Luciano Berio resides within a tempo of 80 beats per minute. The discovery of a constant tempo allowed for a precise rhythmic transcription to be created which found musical structures including large formal sections, subsections, phrases, rhythmic and melodic motives, layers, and dialogue. Analysis of the rhythmic phrases shows that electroacoustic music can have a controlled structure and that these structures earned Thema an enduring legacy of masterpiece. The transcription provides a road-map to compare and contrast different elements that reoccur throughout Thema. The work was composed with a well thought-out and …

LSU Doctoral Dissertations

The slave ship’s hold is the only place Black people put in chains can appropriate. There is no other place they can claim as their own since they know nothing of the New World to which they are being deported by force. A space where the memory of the native land quickly deteriorates, the hold becomes the main “home” with which the uprooted captives can identify. Therefore, it becomes a “lieu de mémoire”, a place that keeps traumatizing the descendants of people enslaved, to the point that it poisons the most intimate space of all: the bedroom. This dissertation is …
