Foundations And Interpretations Of Quantum Mechanics, Cory Johnson

Honors Theses

The first famous thought experiment of Einstein gives rise to his theories of relativity, the bedrock of modern astrophysics and cosmology. His second famous thought experiment begins the investigation into the foundations of quantum mechanics. It leads to a paradox, inspiring various 'no-go' theorems proven by Bell, Kochen, and Specker. Physicists and philosophers worldwide become increasingly dissatisfied with the probabilistic complementarity interpretation (Born-Bohr) and eventually offer their own accounts of the theory. By the end of the 20th century two alternative approaches stand out as the best candidates: Both the hidden variables interpretation (de Broglie-Bohm) and the many worlds interpretation …

Effects Of Context Of Natural And Artifactual Objects On Categorization, Linsey Walker

Honors Theses

Categorization of animals and vehicles in different contexts was investigated in three experiments using event related potentials (ERPs). The presence of a background and congruency of the background in relation to the object were both manipulated in order to determine the effects of context on visual processing. In Experiment 1, adults were presented with images of animals and vehicles in two conditions: situated in a congruent context (e.g. an animal in a field) and in the absence of a context (an animal in a white homogeneous background). In experiment 2, adults were presented with images of animals and vehicles in …

The primary objective of this study is to conduct a review of emergency department (ED) poisonings to characterize its demographics and assess associated co-morbidities. The second objective is to explore correlation between personal history of diseases and poisonings. Predictors for poisonings and its outcomes were investigated and risk factors for suicidal poisoning and how it relates to mental illnesses were explored. Six hundred and forty nine cases admitted to ED between 2004 and 2007 were studied. Results indicate …

Effect Of Hemoglobin-Based Oxygen Carriers On Arterial Pressure And Vasoactivity In The Rat Mesentery, Michael Kim

Theses and Dissertations

Hemoglobin-based oxygen carriers provide a promising future as an alternative to human blood transfusions. Hemoglobin-based oxygen carriers, HBOCs, provide a lowcost, easy to maintain, and safe solution. They require no refrigeration and are universally compatible, and the required transfusion volume is less than that of a normal transfusion. HBOCs have been known to have adverse side effects such as renal toxicity, gastrointestinal dismotility, and hypertension. Many of these problems stem from the lack of a membrane, which protects the hemoglobin from dissociating and extravasating into the blood vessel wall. Extracellular hemoglobin, like that found in HBOCs, has a greater affinity …

Unamunian Microcosms: Four Short Stories In A New Translation Into English, Emily A. Davis

Theses and Dissertations

Spanish writer Miguel de Unamuno's short fiction is neglected in both the academic and nonacademic communities, and it is especially underrepresented in English-language translation. This thesis constitutes a comprehensive approach to four short stories: "El que se enterró," "La manchita de la uña," "Mecanópolis," and "Batracófilos y batracófobos." A detailed exploration of thematic resonances among them, and between these and other works by Unamuno, precedes side-by-side translations of all four texts, of which only "Mecanópolis" has been previously published in English translation.

Data collected for this study were derived from the official transcripts of students enrolled in spring 2007 College Algebra classes of a Mississippi …

Effect Of Phosphorous Poisoning On Catalytic Cracking Of Lipids For Green Diesel Production, Stephen Thomas Dufreche

Theses and Dissertations

Biodiesel is one of the most widely used biofuels in the world, due in part to its simplicity of production, compatibility with existing engines, and reduction of green house gas emissions. However, technical difficulties with biodiesel include: (1) the need of highly refined oil for ASTM compliance, (2) incompatibility with the petroleum-diesel pipeline distribution system, and (3) a relatively small inventory of expensive feedstocks. Issues (1) and (2) could be overcome by the production of biofuels using chemical processes associated with petroleum refining. Catalytic lipid cracking could result in green diesel, a fuel chemically similar to conventional diesel but derived …

Causes Of Whitening Of Ivy Geraniums (Pelargonium Peltatum), Ritu Dhir

Theses and Dissertations

The development of whitening of the youngest leaves of actively growing ivy geranium (Pelargonium peltatum L.) has been observed as the season changes from late spring to summer. This study was conducted to determine the specific environmental causes of whitening, if micronutrients deficiencies cause similar whitening, whether low night temperatures can reverse whitening, and whether salicylic acid affects growth and whitening in ivy geraniums. Two cultivars, ‘Beach’ and ‘Butterfly’, with different susceptibility to whitening were chosen for this study. Elevated air temperature, but not elevated root-zone temperature, was found to be the environmental cause of whitening in ivy geranium. Elevated …

Oxidation Of Lipids In A Supercriticalluid Medium, Darrell Lynn Sparks

Theses and Dissertations

Efficient use of renewable feedstocks for production of chemicals and intermediates is necessary to reduce dependence upon petroleum. A large portion of these chemicals could be produced using lipids from renewable feedstocks such as vegetable oils, animal fats, and bacterial lipids. For example, many lipid sources contain unsaturated fatty acids, which can be oxidized to form a variety of products such as diacids and epoxides. These chemicals are used to formulate herbicides, detergents, plasticizers, lubricants, paints, and other useful products. One of the most common unsaturated fatty acids is oleic acid, and it can be oxidized with an ozone/oxygen mixture …

Toward The Synthesis Of Nuclease Models., Enni Nina Fomumbod

Electronic Theses and Dissertations

Nucleases are enzymes that can specifically recognize nucleic acids and hydrolyze their phosphodiester bonds effectively. As is the case with many hydrolases, nucleases often carry one or more metal centers. Cooperation between such metal centers and other interactions involving general acid-base activities are believed to be essential in multifunctional catalyses. Combination of such interactions in model compounds often resulted in larger than additive effects.

This work is aimed at synthesizing nuclease models that combine the ability to recognize phosphate groups and/or nitrogen bases of DNA together with the ability to catalyze phosphodiester hydrolysis. These models were designed to achieve optimum …

Gender-Specific Differences In Spatial Behavior Of The Flesh Fly, Sarcophaga Crassipalpis., Caleb Joseph Paquette

Electronic Theses and Dissertations

Territoriality in the flesh fly, Sarcophaga crassipalpis (Diptera: Sarcophagidae) was studied in the laboratory. In rectangular enclosures, male flies exhibited a lower tolerance (occupation of the same physical space) of same-sex conspecifics than did female flies. In circular arenas, male flies showed significantly higher levels of spatial separation among themselves (as determined from nearest neighbor analyses) than did females: males were distributed uniformly whereas females were nearly random. The male spatial behavior occurred during the photophase but not the scotophase of light-dark cycles, suggesting that visual cues are required for maintenance of inter-individual spacing. No significant differences in male spacing …

The Study Of The Life Cycle Of Bolbophorus Damnificus And Its Pathology In The Channel Catfish (Ictalurus Punctatus), Marlena Catherine Yost

Theses and Dissertations

In channel catfish (Ictalurus punctatus), the digenetic trematode B. damnificus, causes morality and reduced growth. Previous research has documented the hosts for B. damnificus are: the American white pelican (Pelecanus erythrorhynchos), the snail (Planorbella trivolvis) and the channel catfish. The goals of this research were to confirm the life cycle of B. damnificus in a single life cycle study fulfilling Koch’s postulates; determine if the snail, Biomphalaria havanensis-obstructa, could serve a host for B. damnificus, and examine the pathology of B. damnificus in channel catfish. American white pelicans (AWP) were artificially infected with B. damnificus metacercariae which matured to the …

An Investigation Of Paraoxonase-1 Activities In The Serum Of Southerners As Related To Gender And Race, Kimberly Ann Davis

Theses and Dissertations

Paraoxonase-1 (PON1) has an anti-oxidative function in preventing the formation of oxidized lipoproteins (LDL and HDL) and hydrolyzing the active metabolites of some organophosphate insecticides (e.g., paraoxon and diazoxon) and other non-physiological substrates. PON1Q192R affects PON1 hydrolytic activity and its protective role against oxidative stress, thereby influencing susceptibility to cardiovascular disease among individuals. The objectives of this study were to determine the effect of race, gender, and age on PON1 activities and PON1192 genotypes in Caucasian and African American Southerners. Serum samples from 200 individuals (equally distributed race and gender classes, ages 25-55) were assayed spectrophotometrically for paraoxon and diazoxon …

Axial Pull-Out Strength Of 3.5 Cortical And 4.0 Cancellous Bone Screws Placed In Canine Proximal Tibias Using Manual And Power Tapping, Jennifer Lynn Demko

Theses and Dissertations

Many orthopedic conditions in dogs require the placement of bone screws in the proximal tibial metaphysis. Currently, both cortical and cancellous screws are used clinically depending on the surgeon’s preference; however, the ideal screw for use in the proximal tibia has not been determined. Currently, both the manual and power tapping techniques are used during surgical procedures of the proximal tibia in dogs. However, it is unknown if the use of power tapping when placing screws in the canine proximal tibial metaphysis affects screw purchase. Measurement of axial pull-out strength is traditionally used to evaluate and compare the holding power …

Effects Of Five Different Intensities Of Stand Establishment On Wildlife Habitat Quality And Tree Growth In Loblolly Pine (Pinus Taeda) Plantations In Southern Mississippi, Phillip Daniel Jones

Theses and Dissertations

I evaluated effects of 5 intensive pine plantation establishment regimes during years 1 – 5 post-establishment on vegetation communities, loblolly pine (Pinus taeda) growth, nutritional carrying capacity for white-tailed deer (Odocoileus virginianus), habitat values for northern bobwhite (Colinus virginianus), and projected financial viability in the Lower Coastal Plain of Mississippi. Treatments were combinations of mechanical site preparation (MSP), chemical site preparation (CSP), and herbaceous weed control (HWC) designed to reflect the range of operational intensities on industrial forest lands in the southeastern U.S. Results should inform plantation management decisions throughout the region. Pine growth increased with greater treatment intensity. At …

Productivity Of Raised Seedbeds For Soybean [Glycine Max. (L.) Merr.] Production On Clayey Soils Of The Mississippi Delta, James Brewer Blessitt

Theses and Dissertations

Early planting of indeterminate soybean varieties has increased yield potential in Mississippi. Narrow row patterns have effectively alleviated canopy closure problems and maximized light interception. Stresses related to inadequate drainage persist. Field experiments were conducted in 2006 and 2007 to evaluate productivity and profitability of bedding systems to minimize stresses related to poor drainage. Soybean planted on a conventional 100 cm bedding system provided a higher degree of growth and development and higher seed yields than flat plantings when border irrigated both years. Raised 100 cm-wide beds offered 23 to 45% greater net returns above input costs relative to flat …

The American Expeditionary Forces In World War I: The Rock Of The Marne., Stephen L. Coode

Electronic Theses and Dissertations

American participation in the First World War developed slowly throughout 1917 to a mighty torrent during the last six months of the war. United States participation undoubtedly helped not only repel but to stop all German assaults on the Western Front: it had substantially aided in defeating Imperial Germany.

Through primary and secondary sources a timeline, as well as a few of the more significant events, has been established following the United States' involvement in the war. Special attention has been focused on the United States Third Infantry Division and its part in the July 15- 17, 1918 Second Battle …

Deception In Super Bowl Advertisements: An Analysis Of Deceptive Story Lines, Christopher R. Near

Theses and Dissertations

Many ethical studies have focused on advertising; however, they have yet to focus specifically on Super Bowl advertisements. This thesis examines the ethical issue of portraying deceptive acts within the storylines of Super Bowl advertisements from 1988-2008. Results indicate that 196 of the 2,172 advertisements studied, contain deceptive storylines. Most often the advertisements depicted white males, ages 30-64, using deception. Also, deception was usually done out of self interest at the expense of others. The deception often led to negative social, material, and emotional consequences for the person being deceived, with mostly positive outcomes being shown for the person doing …

Bacterial Source Tracking In The Sinking Creek Watershed Using Antibiotic Resistance Analysis And Ribotyping., Lisa Kathleen Gallagher

Electronic Theses and Dissertations

Fecal pollution of surface water is a significant environmental health issue. Indicator organisms are used to monitor microbial water quality, but often their presence does not coincide with the presence of pathogens. Bacterial source tracking is a term describing methods to determine the origin of fecal pollution based on bacterial traits. The objective of this research is to evaluate the use of 2 bacterial source tracking techniques, antibiotic resistance analysis (ARA) and ribotyping, to determine the sources of bacteria isolated from Sinking Creek. Based on the results of this study, ARA and ribotyping are not useful techniques for identifying sources …

Antigen Trafficking Within Chlamydia Trachomatis-Infected Polarized Human Endometrial Epithelial Cells., David Kelley Giles

Electronic Theses and Dissertations

Chlamydia trachomatis serovars D-K are the leading cause of bacterially-acquired sexually transmitted infections in the United States. As an obligate intracellular pathogen, C. trachomatis infects columnar epithelial cells of the genital mucosae and can cause deleterious sequelae such as pelvic inflammatory disease, infertility, and ectopic pregnancy. Several chlamydial antigens reach the host cell cytosol prior to the natural release of chlamydiae at the end of the developmental cycle. While some of these extra-inclusion antigens traffic to the host cell surface, others remain intracellular where they are proposed to influence vital host cell functions and antigen trafficking and presentation. The research …

Analysis Of The Role Of Bhlh/Pas Proteins In Aryl Hydrocarbon Receptor Signaling, Edward J. Dougherty

USF Tampa Graduate Theses and Dissertations

The aryl hydrocarbon receptor (AHR) is a basic helix-loop-helix PER/ARNT/SIM (bHLH-PAS) transcription factor that binds ligands typified by 2,3,7,8-tetracholordibenzo-p-dioxin, translocates to the nucleus, dimerizes with the aryl hydrocarbon nuclear translocator (ARNT) and associates with specific cis xenobiotic response elements to activate transcription of genes involved with xenobiotic metabolism. AHR-mediated signal transduction has been evaluated thoroughly in the C57BL/6J mouse model system. This model system, however, may not be the most accurate model for human comparisons as the AHR^b-1 allele carried by C57BL/6J contains a point mutation that prematurely truncates the receptor at 805 amino acids, while the AHR^{b-2 …}

The Investigation Of Innate Immune System Memory In Rag1-/- Mutant Zebrafish, Claudia M. Hohn

Theses and Dissertations

The innate immune system in vertebrates is considered to lack specific memory. To investigate innate immune system based immunological protection mediated by cells that are not part of the acquired immune system the Tübingen recombination activation gene1 (rag1)t26683 mutant (MT) zebrafish was chosen. Molecular analysis demonstrated MT zebrafish kidney cells expressed Non-specific Cytotoxic cell receptor protein-1 (NCCRP-1) and Natural Killer cell (NK) lysin but lacked T cell receptor (TCR) and immunoglobulin (Ig) VH1, VH2, VH3 and VH4 expression. Differential counts of peripheral blood leukocytes indicated that MT fish had decreased lymphocyte populations (34.7%) compared to rag1+/+ wild-type (WT) fish (70.5%), …
