Effects Of Selenium On The Freshwater Alga Chlamydomonas Reinhardtii With And Without The Proteasome Inhibitor Mg132, E. Patrick Vallentine

Honors Theses

Selenium is a required nutrient in animal life but has not been shown to be needed in plants. The model plant cell Chlamydomonas reinhardtii may be an exception as it appears to increase its growth rate in the presence of selenium. Because selenium has the same valence state as sulfur it may be incorporated into proteins as the modified amino acid selenocysteine. This incorporation of selenocysteine into protein may disrupt the disulfide bridges that give proteins the correct conformation. Misfolded proteins can wreak havoc on a cell. This stress can be measured through several parameters. Chlorophyll levels, glutathione levels, growth, …

One Art With Two Sides: Theatre And Performance Art, Jacob Watts

Honors Theses

Theatre is typically a scripted performance, performed by actors within a "Theatre space" and observed by an audience. When capitalized, "Theatre" refers to a field of art and study. It is produced to tell a story, or create meaning. Theatre contains elements of plot and characters, often using the characters to tell a story. Visual performance art is art that focuses on live human performance and defines itself in terms of "visual art" and not in terms of "Theatre performance." Performance art does not always occupy a specific place or use a specific kind of script. It often lacks character, …

Improving Commercial Broiler Attic Inlet Ventilation Through Data Acquisition Coupled With Cfd Analysis, Jonathan William Wiley Olsen

Theses and Dissertations

The use of solar heated attic air is an area of increasing interest in commercial poultry production. Attic inlets satisfy the demand for alternative heating while being simple to implement in an existing poultry house. However, little attention has been given to the configuration of the attic space and its influence on thermal energy extraction. This issue was approached in a threefold manner: i.) test case experimental data for the operation of attic inlets in an east-west oriented commercial broiler house was recorded, ii.) a two-dimensional computational fluid dynamics (CFD) attic inlet ventilation model (AIVM) was developed and verified using …

The Effects Of Gestalt Principles On Diagram Comprehension: An Empirical Approach, Krystle Dianne Wilson

Theses and Dissertations

In the software engineering process some tasks of software engineers are to design software documents, analyze the documents, and comprehend component relationships within software diagrams. Those diagrams represent the software architecture which models the structure, behavior, relationships, and constraints among system components while ignoring implementation detail. In the software lifecycle, the system is implemented from the software architecture and errors and mistakes caused from a lack of comprehension or incorrect comprehension could cause engineers to incorrectly design the system. These errors can be defined as lapses, slips, or lack of understanding and fall into three categories: skill, rule, and knowledge …

The purpose of this thesis was to examine what the Olympic glory of Owens represented for society. Owens as an Olympian in 1936 manufactured a brand of social capital that tied people together in commonality—as Americans. As well, in both myth and deed, …

Bacteria And Their Effects On Fertility In The Chicken, Melissa Dawn Haines

Theses and Dissertations

Pathogenic and non-pathogenic bacteria that are commonly associated with Poultry include: Salmonella, E. coli, Campylobacter, Clostridium, Lactobacillus, and Bifidobacterium. These bacteria are often transmitted to the bird from the environment and sometimes to the offspring which may affect bird performance and health. Therefore, the objective of our first experiment was to determine if rooster semen exposed to these bacteria had an effect on sperm motility. Our results indicated that all 6 bacteria lowered sperm motility but the 2 non-pathogenic bacteria, eliminated sperm motility immediately after exposure. These results led to the second experiment which was to determine if semen exposed …

“'They Was Things Past The Tellin’: A Reconsideration Of Sexuality And Memory In The Ex-Slave Narratives Of The Federal Writers’ Project", Lynn Cowles Wartberg

LSU New Orleans Theses and Dissertations

In 1936, Federal Writers’ Project (FWP) employees began interviewing formerly enslaved men and women, allowing them to speak publicly of their experiences under slavery. Defying racism and the repressions of Jim Crow, ex-slaves discussed intimate details of their lives. Many researchers considered these interviews unreliable, but if viewed through the lens of gender and analyzed using recent scholarship on slavery and sexuality, FWP interviews offer new insights into the lives of enslaved men and women. Using a small number of ex-slave interviews, most of them drawn from Louisiana, this thesis demonstrates the value of these oral histories for understanding the …

The Effects Of Intracerebroventricular Leptin On Milk Availability In Lactating Rats, Brittany Lynita Moore

Electronic Theses and Dissertations

Reports have linked energy balance along with adipocyte derived leptin action to improved fertility. Recent evidence indicates that leptin hormone is present in breast milk and leptin receptors are well expressed in mammary epithelial cells. The hypothesis that insufficiency of leptin restraint in the hypothalamus may underlie infertility in rodents and the failure of lactating breast to express adequate amount of milk was tested. Female Sprague-Dawley rats were injected leptin through intracerebroventricular cannulation (ICVC) of the third ventricle. Female rats were mated with stud males and observed throughout gestation. Compared to the control groups, leptin treatment increased prolactin levels in …

Bloodsport And The Michael Vick Dogfighting Case: A Critical Cultural Analysis, Wil Massey

Electronic Theses and Dissertations

After law enforcement officials in Virginia found evidence of a dogfighting operation, the owner, National Football League star Michael Vick, became one of the most vilified figures in America for supporting a bloodsport that inflicts debilitating bodily harm on dogs. This thesis examines that case in light of the long human history of breeding fighting dogs for war and competitive entertainment. A content analysis was performed on a sample of news reports and opinion pieces that were published in three media outlets. Reactions to the Vick case illuminated strong popular opposition to dogfighting. Findings explore how strong anti-dogfighting views appeared …

A Daoist Model For A Kantian Church, Stephen R. Palmquist

Comparative Philosophy

Although significant differences undoubtedly exist between Daoism and Kant’s philosophy, the two systems also have some noteworthy similarities. After calling attention to a few such parallels and sketching the outlines of Kant’s philosophy of religion, this article focuses on an often-neglected feature of the latter: the four guiding principles of what Kant calls an “invisible church” (universality, purity, freedom, and unchangeableness). Numerous passages from Lao Zi’s classic text, Dao-De-Jing, seem to uphold these same principles, thus suggesting that they can also be interpreted as core features of a Daoist philosophy of life. A crucial difference, however, is that members of …

Effects Of Preblending And Water Addition On Physical And Sensory Characteristics Of Seasoned Pork Patties, Molly Sheppard Field

Theses and Dissertations

The objective of this study was to establish the consumer acceptability of preblended and nonpreblended post rigor seasoned pork patties with added water levels of 0, 3, 6, and 9 percent for each formula. Other parameters measured were proximate analysis, texture, cooking loss, and consumer acceptability. Nonpreblended treatments had a higher (P<0.05) percentage of protein and a lower (P<0.05) percentage of fat as compared to preblended treatments. Texture analysis revealed a lower (P<0.05) amount of total energy required to shear through a single patty in preblended treatments than nonpreblended treatments. No differences (P>0.05) were detected among treatments at varying water levels. Consumer acceptability showed no differences (P>0.05) among selected treatments. Consumer acceptability scores indicated that consumers would consume both preblended and nonpreblended seasoned pork patties at varying water levels.

Ecology Of The Tick-Borne Pathogen, Rickettsia Parkeri, In Its Primary Vector, Amblyomma Maculatum, And Select Vertebrate Hosts, Gail Miriam Moraru

Theses and Dissertations

Rickettsia parkeri is a tick-borne microorganism, only recently recognized to cause disease in humans. The ecology of this disease is largely unknown, and was addressed through a series of laboratory and field investigations. Feeding behavior of immature stages of the primary vector, Amblyomma maculatum, on mammalian, avian, and reptilian host models was investigated. It was determined that this tick does not feed on anoles, and nymphs do display longer periods of attachment to and are significantly heavier having fed on cotton rats as compared with quail. Field surveys indicate evidence of exposure to spotted fever group rickettsiae in small mammals …

Effect Of Hand Pinching, Dikegulac-Sodium, And Gibberellic Acid On Chile Pepper (Capsicum Annuum), Abdulfatah Mousa

Theses and Dissertations

Hand Pinching increased branching and fruit yield. At first harvest dikegulac-sodium at 50 ppm increased fruit yield compared to the control. However, dikegulac sodium at 100 ppm reduced fruit yield initially but had no effect on fruit yield at 2-4th harvests. Digkegulac-sodium, Gibberellic acid, and hand pinching did not affect fruit length at third and fourth harvests. However, first and second harvests dikegulac sodium reduced fruit length whereas GA3 had no effect. None of the treatments affected fruit width. Dikegulac sodium and Hand pinching increased the number of branches after three weeks, but GA3 did not. At 8 weeks after …

Cryopreservation Of Equine Spermatozoa: Identification Of Good And Poor Freezer Stallions And Effect Of Sperm Density Per Straw, Abed Sharqy Fahad

Theses and Dissertations

This study was carried out primarily to evaluate the cryo-tolerance of equine semen from four stallions through assessing the spermatozoa motion characteristics with Computer-Assisted Sperm Analysis (CASA). Four stallions were collected during the breeding season (summer). For each ejaculate, fresh and cryopreserved samples were taken for sperm motility characteristics evaluation. Data analysis demonstrated that sperm cells of stallions were significantly affected by (P<0.05) cryodamage. Stallion (A) was cryotolerant, and was classified as a good freezer, whereas stallion (D) was not and classified as a poor freezer regardless of the concentration of sperm. In addition, a concentration of 0.4 x 109 sperm cells/ml had higher percentages of rapid sperm and velocity parameters (P<0.05) compared to 0.8 x 109 sperm/ml. Further research is necessary to identify potential biomarkers for good and poor freezer stallions.

Evaluation Of B-Mode And Color Doppler Ultrasound As Alternative Tools For The Study Of Reproduction, Temperament, And Milk Production- Related Variables In The Bovine, Hector Luis Sanchez-Rodriguez

Theses and Dissertations

An adequate vascular perfusion status is essential not only to maintain life, but to ensure the proper physiology of the different systems that form the animal’s body. Due to its role in the transport of oxygen and nutrients toward, and the removal of cellular waste products away from the body’s tissues, the circulatory system is responsible for the maintenance of body homeostasis. Production related functions in farm animals are not an exception, and directly depend on sufficient vascular physiology. In the past, the study of blood flow in large domestic species was restricted to highly invasive techniques. However, even when …

Evaluation Of Wildrye (Elymus Sp.) As A Potential Forage And Conservation Planting For The Southeastern United States, Jason Brett Rushing

Theses and Dissertations

In the southeastern United States, there is a need for a native, cool-season grass component for restoring and reclaiming grasslands and providing quality forage for livestock. Experiments were conducted on southeastern wildrye [Elymus glabriflorus (Vasey) Scribn. & C.R. Ball] to assess agronomic parameters, and establish a base of information for use in future research and breeding programs. Optimal germination requirements (temperature, light, pH, and physical dormancy) were evaluated. Our data suggests that for southeastern wildrye, the optimal temperature required for germination is between 15 and 20oC. Light treatments (constant dark, constant light, short day, and long day) did not influence …

L222w Of Hemagglutinin Affects The Receptor Binding Affinity Of Avian Origin H3n2 Canine Influenza Virus, Guohua Yang

Theses and Dissertations

Emergence of avian origin and equine origin canine influenza viruses (CIVs) in Asia and the United States brings important concerns. Humans are in closer and more frequent contact with dogs than other common hosts of influenza. Thus, CIV is a potential threat to human health. However, little is known about the determinants of CIV host tropism or the transmissibility of CIVs to humans. An amino acid change (W222L) was implicated in modifying hemagglutinin receptor binding by CIV. This was tested using reverse genetics, glycan microarray and virus histochemistry. Glycan microarray demonstrated that avian-origin CIV (H3N2-222W) bind predominantly to alpha-2, 3 …

Theses and Dissertations

Subterranean termites are ecologically and economically important insects that play major roles in organic matter decomposition and nutrient cycling. The Formosan subterranean termite, Coptotermes formosanus Shiraki, is an invasive species known to cause significant damage in urban areas through aggressive consumption of wooden structures and infestations of living trees. Little is known about the presence and impact of C. formosanus in forested ecosystems of the southeastern U.S. as the majority of studies have taken place in urban settings. This study investigates the prevalence of C. formosanus in localized forests, as well as the utilization of living trees by C. formosanus …

Hearth And Home: Life In And Around A "Kitchen" From Ancient Judah As Excavated At Tell Halif, Tim Frank

Theses and Dissertations

A room with many well-preserved artifacts was excavated at Tell Halif in a level associated with Ancient Judah. By using analogy the use of these artifacts can be compared with that of other similar objects. Analogy is at the heart of archaeological interpretation and allows a more explicit determination of the possible uses of artifacts and their patterning. The artifacts serve as evidence for reconstructing life in and around an archaeologically excavated space. By discerning the patterns of artifact distribution we can interpret how the space might have been used. The room excavated at Tell Halif has strong evidence for …
