Carbon Monoxide Production Is Not Enhanced By Nitrogenase Activity, P. Milligan, G. M. King Dec 2000

Carbon Monoxide Production Is Not Enhanced By Nitrogenase Activity, P. Milligan, G. M. King

Faculty Publications

A diverse group of nitrogen-fixing bacteria and two heme degraders were grown with and without fixed nitrogen sources under oxic and suboxic conditions, with and without addition of heme-containing compounds. Several of the strains produced carbon monoxide (CO) under one or more of these conditions, but nitrogenase activity did not stimulate rates of production relative to controls. Although nitrogenase can reduce CO2 to CO in vitro in the absence of N2, this process likely contributes minimally to CO production in soils under in situ conditions. In contrast, myoglobin or hematin addition under oxic conditions significantly stimulated CO production by the …

A Spatial Inquiry Of Infant Low Birthweight And Cancer Mortality In East Baton Rouge Parish, Louisiana, Esra Qzdenerol Dec 2000

A Spatial Inquiry Of Infant Low Birthweight And Cancer Mortality In East Baton Rouge Parish, Louisiana, Esra Qzdenerol

LSU Historical Dissertations and Theses

Infant low birthweight rate in East Baton Rouge Parish is higher compared to the nation. Cancer is one of the most serious health problems in Louisiana. A few studies have indicated a relationship between the two health outcomes and their environment, but conclusions from these studies have not always been consistent. The spatial and temporal scales of the data and the methods used in these studies contribute to the inconsistent and uncertain results. The spatial patterns of infant low birthweight and cancer mortality in East Baton Rouge Parish from 1993 to 1996 and their relationships with environmental factors at three …

Luciano Berio's Music Theatre: Az/One Musicale, Claudine Canzonire Simonson Dec 2000

Luciano Berio's Music Theatre: Az/One Musicale, Claudine Canzonire Simonson

LSU Historical Dissertations and Theses

Luciano Berio refers to his large-scale works for music theatre not as operas, but as azioni musicali, or musical actions. Berio was able to develop the idea that a large-scale work for music theatre should follow an episodic narrative and allow the music to direct the action of the dramaturgy because of the following influences: his collaborations with Cathy Berberian, Edoardo Sanguineti, Umberto Eco, and Italo Calvino; Brecht's epic theatre; Wagner's music drama; and electronic music. Berio was able to successfully realize his musical action concept with Un re in ascolto, or The King Listens (1984), his first …

Kinetic Characterization Of His-Tagged Cp47 Photosystem Ii In Synechocystis Sp. Pcc6803, Zhao Liang Li, Terry M. Bricker, Robert Burnap

Faculty Publications

Recently, construction of strains of Synechocystis sp. PCC6803 having a His6 extension (His-tag) of the carboxyl terminus of the CP47 protein has been reported (T.M. Bricker et al, Biochim. Biophys. Acta 1409 (1998) 50; M.J. Reifler et al., in: Garab, Pusztai (Eds.) Proc. XIth International Congress on Photosynthesis, 1998). While these initial reports suggest a minimal impact of the His-tag upon Photosystem (PS) II function, a more thorough analysis of the kinetic properties of the modified complex is essential. This communication reports on a more detailed kinetic analysis to assess possible perturbations of PS II due to the genetic addition …

High Phosphorylation Efficiency And Depression Of Uncoupled Respiration In Mitochondria Under Hypoxia, Erich Gnaiger, Gabriela Méndez, Steven C. Hand Sep 2000

High Phosphorylation Efficiency And Depression Of Uncoupled Respiration In Mitochondria Under Hypoxia, Erich Gnaiger, Gabriela Méndez, Steven C. Hand

Faculty Publications

Mitochondria are confronted with low oxygen levels in the microenvironment within tissues; yet, isolated mitochondria are routinely studied under air-saturated conditions that are effectively hyperoxic, increase oxidative stress, and may impair mitochondrial function. Under hypoxia, on the other hand, respiration and ATP supply are restricted. Under these conditions of oxygen limitation, any compromise in the coupling of oxidative phosphorylation to oxygen consumption could accentuate ATP depletion, leading to metabolic failure. To address this issue, we have developed the approach of oxygen-injection microcalorimetry and ADP-injection respirometry for evaluating mitochondrial function at limiting oxygen supply. Whereas phosphorylation efficiency drops during ADP limitation …

Mutational Analysis Of The Tra Locus Of The Broad-Host-Range Streptomyces Plasmid Pij101, Gregg S. Pettis, Stanley N. Cohen Aug 2000

Mutational Analysis Of The Tra Locus Of The Broad-Host-Range Streptomyces Plasmid Pij101, Gregg S. Pettis, Stanley N. Cohen

Faculty Publications

The tra gene of Streptomyces lividans plasmid pIJ101 encodes a 621- amino-acid protein that can mediate both plasmid transfer and the interbacterial transfer of chromosomal genes (i.e., chromosome-mobilizing ability [Cma]) during mating. Here we report the results of in-frame insertional mutagenesis studies aimed at defining regions of Tra required for these functions. While hexameric linker insertions throughout the tra gene affected plasmid and chromosomal gene transfer, insertions in a 200-amino- acid region of the Tra protein that contains presumed nucleotide-binding motifs and that is widely conserved among a functionally diverse family of bacterial and plasmid proteins (K. J. Begg, S. …

Effects Of Prolonged Soil Drought On Ch4 Oxidation In A Temperate Spruce Forest, W. Borken, R. Brumme, Y. J. Xu

Faculty Publications

Our objective was to determine potential impacts of changes in rainfall amount and distribution on soil CH4 oxidation in a temperate forest ecosystem. We constructed a roof below the canopy of a 65-year-old Norway spruce forest (Picea abies (L.) Karst.) and simulated two climate change scenarios: (1) an extensively prolonged summer drought of 172 days followed by a rewetting period of 19 days in 1993 and (2) a less intensive summer drought of 108 days followed by a rewetting period of 33 days in 1994. CH4 oxidation, soil matric potential, and soil temperature were measured hourly to daily over a …

Can Light Echoes Account For The Slow Decay Of Type Iin Supernovae?, Bruce Roscherr, Bradley E. Schaefer Mar 2000

Can Light Echoes Account For The Slow Decay Of Type Iin Supernovae?, Bruce Roscherr, Bradley E. Schaefer

Faculty Publications

The spectra of Type Un supernovae indicate the presence of a preexisting slow, dense circumstellar wind (CSW). If the CSW extends sufficiently far from the progenitor star, then dust formation should occur in the wind. The light from the supernova explosion will scatter off this dust and produce a light echo. Continuum emission seen after the peak will have contributions from both this echo as well as from the shock of the ejecta colliding with the CSW, with a fundamental question of which source dominates the continuum. We calculate the brightness of the light echo as a function of time …

Some Generalizations Of The Kadomtsev-Petviashvili Equations, Michael M. Tom Mar 2000

Some Generalizations Of The Kadomtsev-Petviashvili Equations, Michael M. Tom

Faculty Publications

The question of globalization of solutions of the Cauchy problem for some generalizations of Kadomtsev-Petviashvili equations of the form (ut + upux -Dαxux)x + εuyy = 0, where Dx = (- ∂2x)1/2 and ε = ± 1 is examined. It is shown that for ε = -1 and α ≥ 2, a global estimate on solutions can be derived for large initial data provided that p < 4α/4 + α. A consequence of this is that if a is large enough, the local solution in Hs(ℝ2) can be globally continued. © 2000 Academic Press.

Composition And Method For Chiral Separations, William H. Daly, Drew S. Poche, Stefan J. Thibodeaux, Isiah M. Warner

College of Science Patents

Polymers are disclosed that are useful in performing chiral separations. A synthetic scheme for producing the novel polymers is also disclosed. The alkyl side chains of poly(γ-alkyl-α,L-glutamates) have been altered, allowing the facile substitution of the side chains with pendent functional groups. The compounds may be used as a stationary-phase or pseudo-stationary phase in separation techniques such as high performance liquid chromatography, or electrokinetic capillary chromatography. The novel compounds are water-soluble or water-swellable, and are particularly useful in separations of stereoisomers.

Linking Postsecondary Sub -Baccalaureate Institutional Experience To The Career Planning Needs Of Future Workforce., Joycelyn Harrison Brunswick

LSU Historical Dissertations and Theses

Recent changes in the labor market and predictions by the Bureau of Labor Statistics indicate that many of the jobs available in the 21st century will not require a four-year college degree, in contrast to what many high school students perceive will provide their entree to a successful career. Jobs which will be in demand necessitate highly specialized skills which can be developed at post-secondary sub-baccalaureate (PSSB) institutions. High school graduates who do not have the ability, time, money or inclination to earn a bachelor's degree may well obtain economic security by acquiring those skills in great demand, enabling them …

Studies On The Adsorption Of Di- And Mono-Isocyanides Onto Gold And Plantinum Surfaces., Song Lin Jan 2000

Studies On The Adsorption Of Di- And Mono-Isocyanides Onto Gold And Plantinum Surfaces., Song Lin

LSU Historical Dissertations and Theses

The successful formation and characterization of 1,6-diisocyanohexane (DICH) molecules self assembled onto Au and Pt is realized in this dissertation. Exposure of Au substrates to methanolic solutions of DICH can result in the formation of either a monolayer or polymeric multilayer of DICH. Cyclic voltammograms of solution-phase redox probes at poly(DICH)-coated electrode surfaces (both Au and Pt) exhibit behavior that demonstrates that the poly(DICH) layers are effective transport barriers. Cross-linking of the poly(DICH) films can be increased by treating the poly(DICH) films with aqueous Ni2+ solutions; in addition, the free isocyanide functionalities in the poly(DICH) films can be electrochemically converted …

Synthesis And Characterization Of Alkoxyaniline-Terminated Monomer Monolayers On Gold Surfaces., Keith Cory Schomburg Jan 2000

Synthesis And Characterization Of Alkoxyaniline-Terminated Monomer Monolayers On Gold Surfaces., Keith Cory Schomburg

LSU Historical Dissertations and Theses

Monolayers of 2-(6-mercaptohexan-1-oxy)aniline (AnC6SH) and 2-(7-mercaptoheptan-1-oxy)aniline (AnC7SH) on Au were synthesized and investigated by reflection-absorption infrared (RAIR) spectroscopy and electrochemistry. Electrochemical oxidation of AnC6SH/Au and AnC7SH/Au in 1 M H2SO4 to form ox-AnC6SH/Au and ox-AnC7SH/Au resulted in voltammetry indicative of oligomerization and degradation reactions of the aniline functionality. Scanning of the voltammetric potential between 0.0 and +0.9 V and then back to 0.0 V vs. SSCE twice leads to four surface-confined redox waves occurring at +0.25, +0.45, +0.5, and +0.6 V vs. SSCE. The oxidized monolayers were found to exhibit voltammetry similar to that observed for poly(o-phenetidine), which exhibits redox …

Consumers' Reasoned Behavior Toward American Alligator Leather Products., Yingjiao Xu Jan 2000

Consumers' Reasoned Behavior Toward American Alligator Leather Products., Yingjiao Xu

LSU Historical Dissertations and Theses

This study determined consumers' perception of and attitude toward American alligator leather products and evaluated factors affecting consumers' purchase intention of the products. The Fishbein and Ajzen (1975, 1980) theory of reasoned behavior served as the theoretical framework for the study. The influence of six variables on purchase intention was measured: attitude toward purchase based on product attributes, subjective norm with respect to purchase, traditional attitude toward fashion products (fashion involvement), personality traits (self-confidence and self-consciousness), price perception (price-quality schema and prestige sensitivity), and demographics. The correlation between consumers' usage of media for fashion information and purchase intention was also …

Component Reliability Estimation From Partially Masked And Censored System Life Data Under Competing Risks., Rudi Hendricus Petrus Martinus Arts Jan 2000

Component Reliability Estimation From Partially Masked And Censored System Life Data Under Competing Risks., Rudi Hendricus Petrus Martinus Arts

LSU Historical Dissertations and Theses

This research presents new approaches to the estimation of component reliability distribution parameters from partially masked and/or censored system life data. Such data are common in continuous production environments. The methods were tested on Monte Carlo simulated data and compared to the only alternative suggested in literature. This alternative did not converge on many masked datasets. The new methods produce accurate parameter estimates, particularly at low masking levels. They show little bias. One method ignores masked data and treats them as censored observations. It works well if at least 2 known-cause failures of each component type have been observed and …

Removal Of Manganese In Reservoir Tailwaters As A Function Of Reservoir Operations And River Substrate., Steven Lane Ashby Jan 2000

Removal Of Manganese In Reservoir Tailwaters As A Function Of Reservoir Operations And River Substrate., Steven Lane Ashby

LSU Historical Dissertations and Theses

Removal of reduced manganese in aqueous systems has been described as a two-step process that incorporates a chemical or abiotic step followed by or continued with microbially mediated processes. Field and laboratory studies were conducted to describe the removal of manganese from reservoir tailwaters and partition the abiotic and microbial removal processes. Manganese removal was measured in controlled raceways and in microcosms with four sizes of substrate (cobble, 2.00 to 0.50 mm, 0.50 mm to 0.063 mm, and less than 0.063 mm). Sodium azide was used to inhibit biological uptake. An exponential decay model and a hyperbolic decay model were …

The Rhetoric Of The Benign Scapegoat: President Reagan And The Federal Government., Stephen Wayne Braden Jan 2000

The Rhetoric Of The Benign Scapegoat: President Reagan And The Federal Government., Stephen Wayne Braden

LSU Historical Dissertations and Theses

Ronald Reagan deservedly attained the moniker "The Great Communicator" due to his rhetorical prowess. This dissertation addresses an aspect, governmental scapegoating, of Reagan's rhetorical strategy. Traditional scapegoating theory claims that the scapegoat is either killed or driven from the community. However, I claim that Reagan profited by making a unique use of the scapegoat, one that was benign, the government remained essentially unscathed. The means to analyze Reagan's discourse is Kenneth Burke's cycle of guilt, victimage, redemption and rebirth. Ten speeches of President Reagan are analyzed: both of his Inaugural Addresses, his Economic Recovery Speech, and his seven State of …

The Effect Of Negative Events And Firm Responses On Brand Associations, Organizational Associations, And Brand Evaluations., Chris Patrick Pullig Jan 2000

The Effect Of Negative Events And Firm Responses On Brand Associations, Organizational Associations, And Brand Evaluations., Chris Patrick Pullig

LSU Historical Dissertations and Theses

This dissertation examines the impact of negative events and firm responses to such events on an associative network of brand knowledge; key consumer brand and organizational associations, risk perceptions, and brand response variables. To accomplish this objective the issue of how negative event information is integrated with an existing brand/organizational image was assessed within the framework of a consumer-brand relationship. Two between-subjects experiments were conducted using adult consumers as subjects. In Study One, negative events were found to affect associations linked to the brand and limit the brand's ability to fulfill the consumer-brand relationship. Two types of events were identified, …
