Education, Faith And The Critique Of Reason., Mary Ellington Quinn Jan 1997

Education, Faith And The Critique Of Reason., Mary Ellington Quinn

LSU Historical Dissertations and Theses

The world situation, and life, in the contemporary West, since the rise of modernity, has been described most frequently as one of crisis, marked by a breakdown of life's intelligibility. It is the aftermath of the "death of God," the disappearance of humanity's relationship to a transcendent reality which historically has served as the center of meaning, effecting what has been called the world's disenchantment or the life-world's despiritualization, marked by a loss of soul. This process has involved a reduction of what constitutes the cosmos and human existence in it. In addition, reason, believed in as humanity's guiding principle, …

The Radioresistance Of Deinococcus Radiodurans., Valerie Mattimore Jan 1997

The Radioresistance Of Deinococcus Radiodurans., Valerie Mattimore

LSU Historical Dissertations and Theses

Deinococcus radiodurans is a remarkably ionizing radiation resistant bacterium. As a vegetative cell it is capable of withstanding 5,000 Gy ionizing radiation without evidence of death or mutation. D. radiodurans survives irradiation by repairing DNA damage via an extremely efficient DNA repair system. However, this DNA repair system has not been completely defined. In addition, the selective process allowing the evolution of high level radioresistance has remained a question. This dissertation bolsters the understanding of the DNA repair system of D. radiodurans by characterizing a collection of ionizing radiation sensitive (IRS) mutants. The level of radioresistance is quantified and transformation …

Activation Of Δ-Globin Gene Expression By Erythroid Krupple-Like Factor: A Potential Approach For Gene Therapy Of Sickle Cell Disease, David Donze, Paxson H. Jeancake, Tim M. Townes Nov 1996

Activation Of Δ-Globin Gene Expression By Erythroid Krupple-Like Factor: A Potential Approach For Gene Therapy Of Sickle Cell Disease, David Donze, Paxson H. Jeancake, Tim M. Townes

Faculty Publications

Hemoglobin A2 (HbA2; α2δ2) is a powerful inhibitor of HbS (α2β2/(S) polymerization. However, HbA2 levels are normally low in sickle cell patients. We show that a major reason for low δ-globin gene expression is the defective CACCC box at -90 in the δ-globin promoter. When the CACCC box defect in δ is corrected, expression of an HS2 δ/Luciferase reporter is equivalent to HS2 β/Luciferase. Erythroid Krupple-like factor (EKLF), which binds to the CACCC box of the β-globin gene and activates high-level expression, does not bind to the normal δ-globin promoter. Our goal is to design a modified EKLF that binds …

Effects Of Climate Change On Hypoxia In Coastal Waters: A Doubled Co2 Scenario For The Northern Gulf Of Mexico, Dubravko Justic, Nancy N. Rabalais, R. Eugene Turner Jul 1996

Effects Of Climate Change On Hypoxia In Coastal Waters: A Doubled Co2 Scenario For The Northern Gulf Of Mexico, Dubravko Justic, Nancy N. Rabalais, R. Eugene Turner

Faculty Publications

Projections of general circulation models suggest that freshwater discharge from the Mississippi River to the coastal ocean will increase 20% if atmospheric CO2 concentration doubles. This result is likely to affect water column stability, surface productivity, and global oxygen cycling in the northern Gulf of Mexico, which is the site of the largest (up to 16,500 km2) and most severe hypoxic zone (liter‒1) in the western Atlantic Ocean. We use a coupled physical-biological two-box model to investigate potential effects of climate change on seasonal oxygen cycling and hypoxia in river-dominated coastal waters. The model was developed and calibrated using comprehensive …

Effects Of Predator Reduction On The Survival And Movements Of Northern Shoveler Broods, John M. Zimmer May 1996

Effects Of Predator Reduction On The Survival And Movements Of Northern Shoveler Broods, John M. Zimmer

LSU Historical Dissertations and Theses

I studied the effects of predator removal on survival and movements of Northern Shoveler (Anas clypeata) broods in the prairie pothole region of North Dakota. The study was conducted from April through August 1995. No treatment effects were found on brood survival as both 14 and 30 day survival estimates were statistically equivalent. Experimental sites had higher brood and duckling survival and produced twice as many fledglings per successful nest than control sites. Cumulative movement distance had no effect on duckling survival. While survival rates of Northern Shoveler broods and ducklings were higher than most species of prairie nesting ducks, …

Impact Of The Soft-Shell Clam Mya Arenaria On Sulfate Reduction In An Intertidal Sediment, Kim Hansen, Gary M. King, Erik Kristensen May 1996

Impact Of The Soft-Shell Clam Mya Arenaria On Sulfate Reduction In An Intertidal Sediment, Kim Hansen, Gary M. King, Erik Kristensen

Faculty Publications

Sulfate reduction and various parameters related to the sulfur cycle were examined at mm to cm scales around burrows of the soft-shell clam Mya arenaria in an intertidal sediment (Lowes Cove, Maine, USA). Sulfate reduction rates were 1.5 to 2 times higher in the inner 1 to 5 mm region surrounding the burrow than in ambient sediment In contrast, pools of reduced sulfur increased with the distance from the burrow wall to values ≈1.5 times higher in ambient sediment. The highest numbers of sulfate-reducing bacteria (estimated using a most-probable-number technique) and microbial biomass (estimated from phospholipid phosphorous content) relative to …

Urea Production And Turnover Following The Addition Of Amp, Cmp, Rna And A Protein Mixture To A Marine Sediment, Mette S. Therkildsen, Gary M. King, Bente Aa Lomstein May 1996

Urea Production And Turnover Following The Addition Of Amp, Cmp, Rna And A Protein Mixture To A Marine Sediment, Mette S. Therkildsen, Gary M. King, Bente Aa Lomstein

Faculty Publications

The potential of adenosine 5′-monophosphate (AMP), cytidine 5′-monophosphate (CMP), 16S ribosomal RNA, and a protein (bovine serum albumin) to serve as substrates for bacterial urea production was evaluated in a defaunated, anoxic marine sediment. AMP, CMP and RNA stimulated urea production and urea turnover, but CMP to a lesser degree than AMP and RNA. The increase in urea production and turnover rates took place immediately after AMP, CMP, and RNA were added to the sediment. The rapid response in urea production and turnover rates suggests that the necessary uptake mechanisms and enzymes to utilize the substrates were present constitutively. Addition …

A Palynological Study Of Swamp Sediments At The Poverty Point Archaeological Site, Northeastern Louisiana, Karen Thomas May 1996

A Palynological Study Of Swamp Sediments At The Poverty Point Archaeological Site, Northeastern Louisiana, Karen Thomas

LSU Historical Dissertations and Theses

The Poverty Point site, characterized by elaborate earthworks, was occupied from about 1500 B.C. to 500 B.C. (Webb 1982). The site was the central node for a large manufacturing network at the end of the late Archaic Period. Questions of subsistence and the demise of the culture remain unanswered. This thesis employs a palynological study of a swamp in the Poverty Point archaeological site (16WC5), northeastern Louisiana. Eight cores were taken from a swamp immediately adjacent to the mounds at the site. Loss-on-ignition was done for four cores. Two cores, cores PP5 and PP7 were used for pollen analysis; core …

Genetics Of Oviposition Success Of A Thelytokous Fairyfly Parasitoid, Anagrus Delicatus, James T. Cronin, Donald R. Strong Jan 1996

Genetics Of Oviposition Success Of A Thelytokous Fairyfly Parasitoid, Anagrus Delicatus, James T. Cronin, Donald R. Strong

Faculty Publications

The foraging behaviour of the salt-marsh parasitoid, Anagrus delicatus (Hymenoptera: Mymaridae), is distinguished by few eggs laid per patch of hosts and frequent dispersal among patches. We investigated the within-population genetic variability in six quantitative traits associated with this unusual behaviour: fecundity (lifetime number of eggs), time on a patch, number of ovipositions per patch, oviposition rate, ovipositor length and tibia length (a measure of body size). Forty-one wasp isolines were initiated from single parthenogenetic females from three isolated salt marshes, and were maintained for up to eight generations in the greenhouse. We estimated the genetic variance and broad-sense heritability …

The Ecological Origins And Consequences Of Cattle Ranching In Sixteenth-Century New Spain, Andrew Sluyter Jan 1996

The Ecological Origins And Consequences Of Cattle Ranching In Sixteenth-Century New Spain, Andrew Sluyter

Faculty Publications

Despite the dramatic landscape changes Mexico has undergone due to the introduction of cattle ranching by the Spaniards in the early sixteenth century, the ecological origins of that pastroecosystem have remained obscure. About 1521, Gregorio de Villalobos implanted an Andalusian-derived herding ecology in the Gulf Coast lowlands that involved seasonal movement of cattle between wetlands and hill lands. Land-grant records demonstrate that as the colonial economy expanded, the transhumant model proliferated and came into conflict with those native settlements that had survived the pandemics of the early sixteenth century. In circumventing viceregal laws meant to protect native cultures and ecologies, …

The Htra Stress Response Protease Contributes To Resistance Of Brucella Abortus To Killing By Murine Phagocytes, Philip H. Elzer, Robert W. Phillips, Gregory T. Robertson, R. Martin Roop Jan 1996

The Htra Stress Response Protease Contributes To Resistance Of Brucella Abortus To Killing By Murine Phagocytes, Philip H. Elzer, Robert W. Phillips, Gregory T. Robertson, R. Martin Roop

Faculty Publications

Compared with virulent Brucella abortus 2308, the isogenic htrA mutant PHE1 shows decreased resistance to killing by cultured murine neutrophils and macrophages and significant attenuation during the early stages of infection in the BALB/c mouse model. These findings further define the contributions of the htrA gene product to the pathogenesis of B. abortus infections.

Gastrointestinal Motility And Disease In Large Animals, Christine B. Navarre, Allen J. Roussel Jan 1996

Gastrointestinal Motility And Disease In Large Animals, Christine B. Navarre, Allen J. Roussel

Faculty Publications

An understanding of the relationship between gastrointestinal (GI) motility and disease is imperative for the proper treatment of large animal patients, especially as new therapeutic agents become available. However, the abundance of information that has become available in the last 2 decades makes gaining this understanding a formidable task. This article summarizes the changes in GI motility caused by some common diseases and conditions encountered in large animal practice, such as GI obstruction, postoperative ileus, resection and anastomosis, diarrhea, endotoxemia, GI parasitism, hypocalcemia, and pregnancy.

A Low-Co2-Inducible Gene Encoding An Alanine:Α-Ketoglutarate Aminotransferase In Chlamydomonas Reinhardtii, Zhi Yuan Chen, Mark D. Burow, Catherine B. Mason, James V. Moroney

Faculty Publications

At low-CO2 (air) conditions, the unicellular green alga Chlamydomonas reinhardtii acquires the ability to raise its internal inorganic carbon concentration. To study this adaptation to low CO2, cDNA clones induced under low-CO2 growth conditions were selected through differential screening. One full-length clone is 2552 bp, with an open reading frame encoding 521 amino acids. The deduced amino acid sequence shows about 50% identity with alanine:α-ketoglutarate aminotransferase (Ala AT, EC 2.6.1.2) from plants and animals, and the mRNA of this clone increased 4- to 5-fold 4 h after cells were switched from high-CO2 to low-CO2 growth conditions. The expression of the …

Metabolism Of Gemmules From The Freshwater Sponge Eunapius Fragilis During Diapause And Post-Diapause States, Stephen H. Loomis, Steven C. Hand, Paul E. Fell Jan 1996

Metabolism Of Gemmules From The Freshwater Sponge Eunapius Fragilis During Diapause And Post-Diapause States, Stephen H. Loomis, Steven C. Hand, Paul E. Fell

Faculty Publications

Post-diapause gemmules of the freshwater sponge Eunapius fragilis remained quiescent when maintained at 5°C. Germination occurred within 48 to 72 h following warming to 20°-23°C, culminating with the emergence of a new sponge from the collagenous capsule. Both heat dissipation and oxygen consumption climbed steadily during germination and eventually reached 600% of the starting values. By comparison, energy flow was much lower over the same period of time in diapausing gemmules, clearly demonstrating metabolic depression during diapause. The calorimetric:respirometric (CR) ratio increased significantly from -354 kJ/mol O2 to -541 kJ/mol O2 between hours 3.5 and 56.5 of germination, with an …
