Bindweed And Fire, Joshua Lee Davis Jan 2012

Bindweed And Fire, Joshua Lee Davis

Electronic Theses and Dissertations

Bindweed and Fire is a collection of poems in three sections. The first two sections, Drought and Watermarks, contain short metrical lyrics built around images of fire and water. Sabbath, the third section is a long free-verse poetic sequence in three voices. In ekphrastic poems rich with private symbolism, the first voice attempts to refract through the prism of visual art the relationship between a father and son. Providing a counterpoint to the first, the second voice seeks to qualify, correct, and comment on the private symbolism. The third voice tries to give a wider view of the everyday lives …

Room Temperature Ionic Liquid (Rtil) Membranes For Bio-Methane Dehumidification, Ryan Amos Jan 2012

Room Temperature Ionic Liquid (Rtil) Membranes For Bio-Methane Dehumidification, Ryan Amos

Electronic Theses and Dissertations

Renewable fuels are heavily researched due to the increasing price of and resulting pollution from fossil fuels. The production of useable energy from waste—animal, sewage, discarded food, landfill matter would be a valuable renewable fuel production method. Biogas is a renewable fuel that is produced by anaerobic digestion, composed mainly of methane, carbon dioxide and small percentages of hydrogen sulfide and water vapor. Before this biogas—predominately bio-methane—can be converted to fuel, it must be dehumidified to become useable. Typically membrane-based gas dehumidification uses hydrophilic polymer membrane materials, such as polydimethylsiloxane (PDMS) and cellulose acetate (CA). The main problems with polymer …

Synthesis And Characterization Of Nickel Complexes With Relevance To Nickel Acireductone Dioxygenase And Nickel Superoxide Dismutase, Margo Nicole Montgomery

Electronic Theses and Dissertations

This research presents an investigation of synthetic model complexes with relevance to the active site of Ni(II) acireductone dioxygenase (Ni-ARD) and Ni(II) superoxide dismutase (Ni-SOD). Acireductone dioxygenases (ARDs) are a unique set of enzymes found in the methionine salvage pathway that catalyze the oxidation reaction of acireductone (1, 2-dihydroxy-3-oxo-5-(methylthio)pent-1-ene). These enzymes share a compolypeptide sequence but bind different metal ions, Ni2+ or Fe2+, at the active site. The Ni-ARD enzyme is responsible for the off pathway shunt in the pathway. Using the tridentate nitrogen donor ligands hydrotris(3,5-dimethyl-1-pyrazolyl)borate (Tp*) and the newly developed tris(1, 2-dimethyl-4-imadozyl)carbinol, (4-TICMe, Me) several reactions involving the …

Masculinity In Comparative Black Literatures, Latoya Renee Jefferson Jan 2012

Masculinity In Comparative Black Literatures, Latoya Renee Jefferson

Electronic Theses and Dissertations

This project examines the ways in which Black men in Africa and throughout the African Diaspora define themselves as gendered beings in their fiction and drama beginning with Richard Wright's publication of Native Son in 1940 to Mariama Ba's So Long a Letter published 1980. Black men created a transnational dialectic concerning their masculinity which involved the creation and criticism of several types of masculinity. In Chapters 1 and 2, I discuss the theoretical and the historical framework for this project. In Chapter 3, I discuss the first type of Black masculinity which was based in opposition to Euro-American stereotypes …

Functional Studies Of Novel Bioactives From Complex Host-Microbiomes As Drug Leads For Cancer, Infectious Disease, Depression And Pain, John Jason Bowling Jan 2012

Functional Studies Of Novel Bioactives From Complex Host-Microbiomes As Drug Leads For Cancer, Infectious Disease, Depression And Pain, John Jason Bowling

Electronic Theses and Dissertations

The drug discovery process has become increasingly complex in comparison to early efforts particularly those involving diseases or conditions that affect large numbers of the human population. It is difficult to point directly to one factor leading evolution of the process but the definition of a mechanism of pharmacological action for a drug lead has noticeably become a higher priority. This evolution has helped diminish the stigma of natural products and compound supply issues. The issue of compound supply has also been addressed to some extent with the emergence of recombinant technologies and new synthetic methodology. With approximately 60 years …

Inspection Of Earthen Embankment Dams Using Time Lapse Electrical Resistivity Tomography, Jared Stewart Case Jan 2012

Inspection Of Earthen Embankment Dams Using Time Lapse Electrical Resistivity Tomography, Jared Stewart Case

Electronic Theses and Dissertations

According to the National Inventory of Dams (NID), the number of dams across the United States is approximately 85,000. Many of these dams are more than 50 years old and need vast attention to ensure their safety. It is difficult to obtain a full assessment of the dam just by visual inspections alone. This is because many problems associated with dam failure occur internally, which makes it difficult to be observed by the dam inspectors. Examples of these flaws are piping and seepage (flow of water through or around dam walls). It is in this area where geophysical methods can …

Between God And Man: Community's Place In Virtue, Practical Reason, And Transcendent Good, Jordan Herz Davis Jan 2012

Between God And Man: Community's Place In Virtue, Practical Reason, And Transcendent Good, Jordan Herz Davis

Electronic Theses and Dissertations

Talbot Brewer's Retrieval of Ethics and Robert Adams's Finite and Infinite Goods present distinct theories in ethics and metaethics. Brewer begins with the fundamental ethical perspective of the practical deliberator who experiences his practical deliberations as a continuous, unified, and constantly revised activity which begins with inchoate intimations of goodness and proceeds better or worse to understand and pursue the goodness which pervades his evaluative outlook. From this Brewer aims to account for how we achieve excellence in practical deliberation and arrive at a more tenable and self-consistent evaluative outlook which informs our ethical deliberations. Alternately, Adams begins in the …

Problems With Truth: Scope, Mixing, And Truth Pluralism, Christopher Dyer Jan 2012

Problems With Truth: Scope, Mixing, And Truth Pluralism, Christopher Dyer

Electronic Theses and Dissertations

In this paper, I will be taking up the debate between monistic and pluralistic inflationary theories of truth. Truth monism claims that there is one explanatory story which accounts for the truth of all and only true propositions. There seem to be, however, certain domains of discourse wherein monistic theories fail. If monistic theories cannot provide an explanation for how all true propositions are true, then they would not be adequate theories of truth. Truth pluralism is motivated to avoid the scope problem. The pluralist sees that there are as many truth properties as there are domains of discourse. A …

The Art Of Going Beyond In Hossana, Ethiopia, Megan Elizabeth Flowers Jan 2012

The Art Of Going Beyond In Hossana, Ethiopia, Megan Elizabeth Flowers

Electronic Theses and Dissertations

In this study, I examine what education as development means for the men and women who live in Hossana town, Ethiopia. The ethnographic focus of this study is on understanding how education as development evokes different meanings for socio-political participation by rural students at a teacher training college and townspeople respectively. I discuss these conceptual differentiations in relation to the changes in beliefs and strategies that have occurred in Hossana and greater Ethiopia elsewhere over the course of several decades of local and global changes in the social order. I use the emic category of yilhunnta, as the social recognition …

Synthesis And Evaluation Of Naturally Occuring Halogenated Bipyrroles In A Relevant Marine Species, Fundulus Heteroclitus, Kimberly Sheree Foster Jan 2012

Synthesis And Evaluation Of Naturally Occuring Halogenated Bipyrroles In A Relevant Marine Species, Fundulus Heteroclitus, Kimberly Sheree Foster

Electronic Theses and Dissertations

Halogenated dimethyl-2-2'-bipyrroles (HDBPs) have recently been discovered in seabird eggs and have been shown to bioaccumulate in trophic organisms. HDBPs are suspected to be biogenic in nature, derived from evidence of marine natural products that are persistent in the environment and widespread in the Pacific and Atlantic Ocean. The HDBPs exhibit chlorinated and brominated substitution patterns that closely resemble anthropogenic pollutants like the polychlorinated biphenyls (PCBs), polybrominated biphenyls (PBBs), and polybrominated diphenyl ethers (PBDEs). Environmental health concerns exists regarding these naturally occurring HDBPs because several of these analogs were shown to induce the cytochrome P4501A (CYP1A) gene through activation of …

Two Trains Running: Capture And Escape In The Racialized Train Cars Of The Jim Crow South, 1893-1930, Raleigh Mixon Robinson

Electronic Theses and Dissertations

The role of the railroad in the modern American experience—and its role in making that experience modern—cannot be overstated. This thesis proposes to tell one of many possible railroad stories. By focusing on the historical and cultural relevance of a series of bodies in transit, I examine the implementation of railroad segregation law and the response by African-American performers. The thesis begins at the end of the nineteenth century with the Homer Plessy test case and continues across three decades, meeting along the way novelists Charles Chesnutt and James Weldon Johnson and musicians W. C. Handy, Henry "Ragtime Texas" Thomas, …

Finite Element Modeling Of Seismic Wave Propagation In Earthen Embankments, Binyam Tadese Jan 2012

Finite Element Modeling Of Seismic Wave Propagation In Earthen Embankments, Binyam Tadese

Electronic Theses and Dissertations

The detection of internal seepage zones in embankments (dams and levees) by geophysical seismic techniques such as seismic refraction is limited by a number of factors. Some factors are associated with inversion and smoothing problems during processing, while others are associated with the natural characteristics of embankments and seepage anomalies. In this research, changes in the seismic response associated with: embankment soil compositions and moisture, characteristics of the seepage zone, presence of water in the reservoir, and shape of embankment was studied via 2D and 3D finite element (FE) embankment models. Artificial reflections from external boundaries and numerical dispersion were …

The Effect Of Exercise On Mechanical Pressure Pain Threshold In The Presence And Absence Of Delayed-Onset Muscle Soreness, Brandon Tynes Jan 2012

The Effect Of Exercise On Mechanical Pressure Pain Threshold In The Presence And Absence Of Delayed-Onset Muscle Soreness, Brandon Tynes

Electronic Theses and Dissertations

Research has shown decreased pain sensitivity (hypoalgesia) during and following maximal and sub-maximal isometric exercise (Koltyn, 2002). Research on fibromyalgia patients however has shown the same exercises increase pain sensitivity (hyperalgesia) (Staud, Robinson, & Price, 2005; Kosek, Ekholm, & Hansson, 1996). The purpose of the present study was to examine the effects of exercise on pressure pain thresholds (PPT) in the presence and absence of delayed-onset muscle soreness (DOMS) within the ipsilateral (contracting) and contralateral quadriceps muscle and plurisegmental finger. Data were collected using twenty-five male participants (aged 18-29) over five testing days: two days of familiarization, one day of …

Nothing Less Than An Activist: Marge Baroni, Catholicism, And The Natchez, Mississippi Civil Rights Movement, Eva Elizabeth Walton Jan 2012

Nothing Less Than An Activist: Marge Baroni, Catholicism, And The Natchez, Mississippi Civil Rights Movement, Eva Elizabeth Walton

Electronic Theses and Dissertations

This thesis is a religious and social history of the life of Natchez, Mississippi Catholic activist Marjorie R. Baroni (1924-1986). The study examines Baroni's Catholic faith-driven activism as a counter-narrative to the dominant Protestant narratives of religious motivations in the greater civil rights movement. In analyzing Baroni's story as a lived theological drama, I offer Baroni as a vessel for studying often overlooked Catholic influences in the movement: (1) The activist Catholic faith promoted by Dorothy Day and the Catholic Worker Movement (2) The effects of the more inclusive decrees of the Second Vatican Council (1962-1965) on the Catholic Church …

Isolation, Structure Elucidation And Biological Evaluation Of Natural Products From Plants And Fungi, Xiaoning Wang Jan 2012

Isolation, Structure Elucidation And Biological Evaluation Of Natural Products From Plants And Fungi, Xiaoning Wang

Electronic Theses and Dissertations

Natural products have provided considerable value for drug discovery over the past half-century. Nearly four fifth of drugs were natural products or inspired by natural compounds. Bioactive secondary metabolites isolated from natural source, either fungal or terrestrial, are relatively safer for human health and the environment and can serve as drug or as drug leads for the development of synthetic or semi-synthetic analogs. Natural products have also been successfully used in agriculture as plant growth regulators, signal transductions, fungicides, herbicides and tranquilizers. In our continued efforts to identify bioactive compounds, seventy-seven plant and fungal extracts were evaluated using a direct-bioautography …

Antileishmania Compounds From An Unidentified Endophytic Fungus And Biotransformation Of 5,7,2`,4`,5`-Pentahydroxyflavonol, Ahmed Idris

Electronic Theses and Dissertations

Leishmaniasis is a parasitic disease remaining a major public health problem. It causes illness and death especially in developing countries. Comchemotherapeutic agents currently used are often inadequate, requiring long courses of parenteral administration, having toxic side effects or becoming less effective due to the emergence of resistant strains. Thus, there is an urgent need for new, effective, and inexpensive drugs. In the fight against leishmaniasis, natural products are important sources of novel therapeutic agents. The goal of our research is to study secondary metabolites from endophytic fungi as a source of effective antileishmanial agents. Many crude extracts from endophytic fungi …

Bacterial And Sediment Transport In An Artificial Sand Bed Stream During Unsteady Flow, Mary Alexandra Mccaskill Jan 2012

Bacterial And Sediment Transport In An Artificial Sand Bed Stream During Unsteady Flow, Mary Alexandra Mccaskill

Electronic Theses and Dissertations

Storms cause a substantial increase in the fecal indicator bacteria (FIB) concentrations in stream water. Causes for this concentration increase include FIB-laden stormwater runoff and the release of bacteria from stream-bottom sediments. Studies were carried out to quantify this second cause of water quality impairment. Coliform bacteria are a group of FIB, indicate the presence of pathogenic microorganisms, and have been shown to be transported in streams far from their source areas, especially during storms. FIB transport is dependent on several factors including water velocity, size and transport rates of bed sediments, and the FIB concentration in bed sediment. The …

Virtual Worlds And Conservational Channel Evolution And Pollutant Transport Systems (Concepts), Chenchutta Denaye Jackson Jan 2012

Virtual Worlds And Conservational Channel Evolution And Pollutant Transport Systems (Concepts), Chenchutta Denaye Jackson

Electronic Theses and Dissertations

Many models exist that predict channel morphology. Channel morphology is defined as the change in geometric parameters of a river. Channel morphology is affected by many factors. Some of these factors are caused either by man or by nature. To combat the adverse effects that man and nature may cause to a water system, scientists and engineers develop stream rehabilitation plans. Stream rehabilitation as defined by Shields et al., states that "restoration is the return from a degraded ecosystem back to a close approximation of its remaining natural potential" [Shields et al., 2003]. Engineers construct plans that will restore streams …

Temporal And Spatial Assessment Of Pahs In Water, Sediment, And Oysters As A Result Of The Deepwater Horizon Oil Spill, Meghan Christina Dailey Jan 2012

Temporal And Spatial Assessment Of Pahs In Water, Sediment, And Oysters As A Result Of The Deepwater Horizon Oil Spill, Meghan Christina Dailey

Electronic Theses and Dissertations

On April 20, 2010, BP's Deepwater Horizon oil rig exploded leaking over 200 million gallons of crude oil into the Gulf of Mexico for 84 days. Exposure to oil-associated polycyclic aromatic hydrocarbons (PAHs) in the water and sediment could severely impact the aquatic organisms inhabiting the Gulf of Mexico (i.e. developmental defects, reproductive effects, death, etc.). Therefore, water, sediment and oyster, Crassostrea virginica, samples were collected approximately bimonthly between May 26 and November 30, 2010 from multiple sites along the Gulf Coast, namely, two sites in Mobile Bay (Denton and Sand Reefs at 1 or 0.1 m above the bay …

Reconfigurable Wideband Circularly Polarized Microstrip Patch Antenna For Wireless Applications, Ahmed Khidre Jan 2012

Reconfigurable Wideband Circularly Polarized Microstrip Patch Antenna For Wireless Applications, Ahmed Khidre

Electronic Theses and Dissertations

In this thesis, developments of rectangular microstrip patch antenna to have circular polarization agility with wideband performance, for wireless applications are presented. First, a new technique to achieve circularly polarized (CP) probe feed single-layer microstrip patch antenna with wideband characteristics is proposed. The antenna is a modified form of the popular E-shaped patch, used to broaden the impedance bandwidth of a basic rectangular patch antenna. This is established by letting the two parallel slots of the E-patch unequal. Thus, by introducing asymmetry two orthogonal currents on the patch are excited and circularly polarized fields are realized. The proposed technique exhibits …

Picking Up The Pieces, Michael Presley Satterfield

Electronic Theses and Dissertations

Over time wooden and metal objects, such as utility poles, construction lumber, parts from cars, trucks, farm equipment, and heavy machinery, and even an old abandoned car, have become unserviceable and discarded. Lying useless until discovered by the creative explorer, they are reclaimed and become precious raw materials in an artistic project. This body of work is about our ability to pick up the pieces after a time of being at a low point in life. It is about being uplifted by a companion, memory, or idea to a better state of mind or place. The materials I choose for …

There Is No Dishonor In Desertion: Army Racial Intolerance And African-American Soldiers' Desertion, Steve Wallace Jan 2012

There Is No Dishonor In Desertion: Army Racial Intolerance And African-American Soldiers' Desertion, Steve Wallace

Electronic Theses and Dissertations

The thesis focuses on a study concerning the desertion of African-American soldiers from the United States Army. The data were collected from the period covering the War of Independence to the mid-1960s of the Cold War. The study proposes that there are limits to which these soldiers cannot bear the burden of combat and the simultaneous fight against institutionalized racism. Some men endured their circumstances in spite of pervasive intolerance, but others simply could not make sense of the inconsistencies of their government's requirement for them to fight yet deny them basic human rights. The men believed they had the …

Your Body Is A Temple: Type-2 Diabetes In Mississippi And The Potential Role Of The Black Church In Diabetes Education And Intervention, Jonathon Troy Jackson Jan 2012

Your Body Is A Temple: Type-2 Diabetes In Mississippi And The Potential Role Of The Black Church In Diabetes Education And Intervention, Jonathon Troy Jackson

Honors Theses

Type-2 diabetes and obesity are two major health complications that are affecting many Mississippians, namely the African American population. A substantial amount of research has been conducted that explains the high prevalence rate of type-2 diabetes and obesity in the African American community as partially due to many secondary factors, including the Southern cuisine, food scarcity, physical inactivity, and poverty. Recently, efforts to reach the African American population about diabetes education and prevention in other Southern states have been directed to faith-based organizations. Researchers have hoped that faith-based intervention might be better suited at helping a wider audience in a …

Into The Magic Mirror: The Narratives That Reflect Our Lives And Dictate How We Should Live, Chany Fehr Buchanan Jan 2012

Into The Magic Mirror: The Narratives That Reflect Our Lives And Dictate How We Should Live, Chany Fehr Buchanan

Honors Theses

This thesis investigates the influence fairytales have on society, how they dichotomously reflect cultural worldviews yet set standards for appropriate behavior and prescribe hegemonic ideologies. It specifically explores the fairytales told in America over the last couple of centuries, examining how those stories have evolved in correlation with the shifting values of the country. Each chapter lays a foundation for how certain characters are normally portrayed in fairytale tradition - the hero, the beauty, and the villain - and then evaluates how our culture has Americanized those figures, consequently making each of them less idealistic or archetypal and evolution of …
