Purification And Antioxidant Activities Of Soybean Isoflavones, Qiju Wu Jan 2003

Purification And Antioxidant Activities Of Soybean Isoflavones, Qiju Wu

LSU Master's Theses

An efficient procedure was developed and used to extract and purify isoflavones from defatted soy flour. The purity of the final product reached 94%. The antioxidant activities of soybean isoflavones (genistein and daidzein purchased from Sigma Chemical Co, and a mixture of isoflavone glycosides extracted from defatted soy flour) were investigated by a cholesterol oxidation model accelerated by 2,2’-azobis(2-methylpropionamidine) dihydrochloride (AAPH). All components exhibited very high antioxidant activities in the inhibition of cholesterol oxidation. Genistein had higher inhibition to the formation of 5,6beta-epoxycholesterol (5,6b-EP) and 7-ketocholesterol (7-keto), while no significant difference was found between the antioxidant activities of daidzein and …

Pcr Inhibition And Toxic Effects By Sediment Samples Exposed To Drilling Muds, Neal Gilpin Satterly Jan 2003

Pcr Inhibition And Toxic Effects By Sediment Samples Exposed To Drilling Muds, Neal Gilpin Satterly

LSU Master's Theses

This study evaluated the PCR inhibition and toxic effects by sediment samples exposed to drilling muds. This information was gathered in an attempt to identify what effect, if any, drilling muds had on the microbial community structure in sediments around four specific oil-drilling platforms in the Gulf of Mexico. Sediment samples were taken before and after drilling had taken place around two platforms (GB516 and VK916), and sediment samples were taken after drilling had taken place around two other platforms (MC292 and GB602). After using traditional, non-selective DNA extraction methods, successful amplification took place via PCR with all pre-drilling samples …

Effectiveness Of Copper-Oxide Wire Particles On The Control Of Haemonchus Contortus In Sheep, Ariane Diane Watkins Jan 2003

Effectiveness Of Copper-Oxide Wire Particles On The Control Of Haemonchus Contortus In Sheep, Ariane Diane Watkins

LSU Master's Theses

Among the gastrointestinal nematode parasites that cause the most problems to small ruminants, Haemonchus contortus is one of major concern. Currently, the control of H. contortus and others is almost entirely based on the use of anthelmintics. Consequently, anthelmintic resistance has developed worldwide and this has become a serious problem in small ruminant nematode parasite control programs. In view of this, there is a need for alternative control methods. The use of Copper-Oxide Wire Particles (COWP) to help reduce parasite burden is one such alternative. Three trials were conducted to determine the effect of COWP on the reduction of H. …

Truth's Veil: Language And Meaning In Merleau-Ponty And Derrida, Helen Troy Mellon Jan 2003

Truth's Veil: Language And Meaning In Merleau-Ponty And Derrida, Helen Troy Mellon

LSU Master's Theses

The linguistic structuralism of Ferdinand de Saussure (1857-1913) attracted the attention of Maurice Merleau-Ponty, prompting what is thought to be Merleau-Ponty’s “linguistic turn” of 1947. Saussure’s theory of the self-referential structure of linguistic signs as constitutive of value, was tied by Merleau-Ponty to his conception of the structure of intercommunication as constitutive of human value and meaning. Jacques Derrida, in the 1960s, also appealed to Saussure’s theory in formulating his thesis of a deferring and differing relationship between linguistic signs as constitutive of meaning, but rejected what he saw as the privileging of a metaphysics of presence-to-meaning in Saussure. One …

Feasibility Of Restoring The Louisiana Black Bear (Ursus Americanus Luteolus) To Portions Of Their Former Range, Kyle Ryan Van Why Jan 2003

Feasibility Of Restoring The Louisiana Black Bear (Ursus Americanus Luteolus) To Portions Of Their Former Range, Kyle Ryan Van Why

LSU Master's Theses

Black bears (Ursus americanus) historically occurred throughout much of North America’s forested landscapes, but loss of critical habitat and overharvest significantly reduced abundance and distribution. In the southeastern United States, black bear conservation has become a high priority and restoration has been suggested y to recolonize suitable habitat. My study focused on evaluating restoration of the Louisiana black bear (U. americanus luteolus) to the Red River Complex (RRC) in east-central Louisiana. This involved translocating female bears with new born cubs from source populations within Louisiana and monitoring their movements, habitat use, and social acceptance of the restoration program to determine …

Optimal Age At Fostering For The Derivation Of Helicobacter Hepaticus-Free Mice, Kem Boullion Singletary Jan 2003

Optimal Age At Fostering For The Derivation Of Helicobacter Hepaticus-Free Mice, Kem Boullion Singletary

LSU Master's Theses

Helicobacter hepaticus is well established as an unwanted variable in laboratory rodent colonies. Historically, caesarean section and embryo transfer have been used to derive Helicobacter-free mouse colonies. Neonatal transfer of newborn mice onto Helicobacter-free foster dams was recently reported as an alternative method of deriving Helicobacter-free mice, but until now, the age by which pups must be fostered to remain Helicobacter-free was unknown. The purpose of this study was to determine the age by which mouse pups must be fostered to remain H. hepaticus-free. Beginning on the day of birth, 20 C57BL/6 mice were fostered from H. hepaticus-positive parents onto …

Bathroom Issues, Craig Edward Clifford

LSU Master's Theses

"Obscenity is a human manifestation. The toilet has no central nervous system. No level of consciousness. It is not aware; it is a dumb toilet; it cannot be obscene; it's impossible." Lenny Bruce How to Talk Dirty and Influence People Things that make people uncomfortable intrigue me and I find that these same things are very ones that make us laugh the hardest. The fact that sex and bodily functions both make people laugh in addition to making them feel uncomfortable is no accident.

As The Ravens Watch: Exploring The Oracle, Kathryn Lavender Hunter Jan 2003

As The Ravens Watch: Exploring The Oracle, Kathryn Lavender Hunter

LSU Master's Theses

I believe in the process in which the artist never works alone but always in collaboration with the elements of chance. As an artist I live and work everyday collaborating with chance, from reading my cards to creating ethereal birds. As I sew pieces together, the thread becomes another element of the image by chance, stitches to lines, lines to pattern. Chance leads the birds to portraying their own personality as they are each created, one’s head tilts to the right while another sits tall with dignity. This work is about the connection to the subconscious, my connection to it …

Habitat Assessment And Subspecies Identification Of Sandhill Cranes Wintering In Louisiana, Joseph Michael Mcgowan Jan 2003

Habitat Assessment And Subspecies Identification Of Sandhill Cranes Wintering In Louisiana, Joseph Michael Mcgowan

LSU Master's Theses

The two biggest flocks of Sandhill Cranes (Grus canadensis) wintering in Louisiana are located in Cheneyville and Holmwood, LA. Resident Sandhill Cranes were once located in Louisiana, but because of habitat loss and over harvest these residents were extirpated from Louisiana in the early 1900’s. In the 1960’s, migrating Sandhill Cranes had returned to LA and were wintering in Cheneyville. Observations and habitat characteristics were conducted on these two flocks in the winter of 2002 and 2003 because of the lack data on these flocks. The two flocks contained about 1,300 individuals with four other known flocks throughout Louisiana ranging …

Temperature Dependent Kinetics Of Biotin Carboxylase, Brett K. Lord Jan 2003

Temperature Dependent Kinetics Of Biotin Carboxylase, Brett K. Lord

LSU Master's Theses

Acetyl-CoA carboxylase catalyzes the first committed step in long chain fatty acid biosynthesis. In Escherichia coli, the enzyme is composed of three distinct protein components: biotin carboxylase, biotin carboxyl carrier protein, and carboxytransferase. The biotin carboxylase component has served for many years as a model for mechanistic studies devoted toward understanding biotin-dependent carboxylases. Studies of the temperature dependence, temperature dependence of the kinetic solvent isotope effect and thermodynamics of biotin carboxylase are reported. Analysis of the van’t Hoff plot in H2O was biphasic showing an apparent transition temperature of 20°C, with corresponding DH° values of –4.55 ± 1.84 kcal/mol below …

Remembrances Of Things Past And Future: Memory And Its Significance For Politics In Nietzsche, Sophocles, And Isaiah, Michael Henderson Jan 2003

Remembrances Of Things Past And Future: Memory And Its Significance For Politics In Nietzsche, Sophocles, And Isaiah, Michael Henderson

LSU Master's Theses

This thesis is an inquiry into memory and its significance for politics as described in three sources. Part of its task is to grasp Nietzsche’s phenomenology of memory thought and to inquire into what understanding about politics emerges. Nietszche speaks about memory with respect to the self, yet he offers little elaboration about intersubjectivity or transcendence for linking memory to justice. To further investigate his approach, this essay examines two other texts, Philoctetes, by Sophocles, and Isaiah, which set this discussion on a political stage. What emerges is an approach to how memory can have an impact on self, community, …

Out The Loop, Matthew Christian Anderson Jan 2003

Out The Loop, Matthew Christian Anderson

LSU Master's Theses

Often referred to as resembling an architectural blueprint, the screenplay is known for its laconic style. Discarding the subjective abstractionism of a more flowery writing, the screenplay's brevity forces the writer to make use of the physical world of the text to display its underlying currents of thought. This trend in artistic representation, of which the influence has been heatedly discussed since the onset of the cinema, is not stagnant but evolving. The screenwriters of today produce their craft with an increased savoir faire not only in relation to plot and form but also in regards to the aesthetics of …

Equine Immunity To Cyathostome Infections, Marie Alexandra Baudena Jan 2003

Equine Immunity To Cyathostome Infections, Marie Alexandra Baudena

LSU Doctoral Dissertations

To study the protective responses of cyathostome-infected ponies, two challenges were performed employing animals with different histories of exposure to these parasites. The hypothesis developed and to be tested in these experiments was that ponies that had longer exposure to cyathostome contaminated pastures would express acquired resistance to infection. The assumption behind this hypothesis was that helminth-naïve ponies infected with cyathostomes would eliminate the infection using only innate immune responses. Whereas previously exposed ponies would eliminate the infection with acquired immune responses, and these would be more effective in ponies with longer exposure to cyathostomes. Thus, helminth-naïve animals would acquire …

"Science In Skirts": Representations Of Women In Science In The "B" Science Fiction Films Of The 1950s, Bonnie Noonan Jan 2003

"Science In Skirts": Representations Of Women In Science In The "B" Science Fiction Films Of The 1950s, Bonnie Noonan

LSU Doctoral Dissertations

This project shows how central representations of women in science were to the “B” science fiction films of the 1950s and uses these films as valuable indicators for cultural analysis. I argue that the emergence of the modern American science fiction film in 1950 combined with the situation of post-W.W.II women in science to create a genre explicitly amenable to exploring the tension between a woman’s place in the home and her place in the work force, particularly in the fields of science. Out of a context of 114 “B” science fiction films produced between 1950 and 1966, I offer …

Imagining Corporate Culture: The Industrial Paternalism Of William Hesketh Lever At Port Sunlight, 1888-1925, Jeremy David Rowan Jan 2003

Imagining Corporate Culture: The Industrial Paternalism Of William Hesketh Lever At Port Sunlight, 1888-1925, Jeremy David Rowan

LSU Doctoral Dissertations

At Lever Brothers soap company in Port Sunlight, U.K., William Lever, between 1888-1925, instituted employee benefits that preceded the welfare state. Yet, in addition to providing tangible benefits for the employees (including free medical care, pensions, an employee profit-sharing scheme), Lever also created a strong corporate identity for his employees by cultivating a strong company and personal image, one constructed in response to national discourses surrounding industrialization, empire, national identity, and economic decline. Lever offered his company as a solution to national concerns and thus posited his workers as participants in patriotic efforts and empire-building. He forged an effective company …

Effects Of Fire Intensity On Groundcover Shrubs In A Frequently Burned Longleaf Pine Savanna, Jarrod Matthew Thaxton Jan 2003

Effects Of Fire Intensity On Groundcover Shrubs In A Frequently Burned Longleaf Pine Savanna, Jarrod Matthew Thaxton

LSU Doctoral Dissertations

Variation in fire intensity may affect the structure and composition of frequently burned plant communities. I hypothesize that small-scale variation in fuel loads affects fire intensity within single fires in frequently burned savannas. Furthermore, I expect that local differences in fire intensity produce predictable patterns to the demography of groundcover shrubs. I tested these hypotheses by manipulating fuel loads in a longleaf pine savanna. Fuel load treatments consisted of fine fuel removal, pine needle addition, wood addition and unaltered control, mimicking naturally occurring fuel load variation. Treatments were repeated in 1m2 subplots over two sets of biennial burns and shrub …
