Steric Hindrance As A Mechanistic Probe For Olefin Reactivity:  Variability Of The Hydrogenic Canopy Over The Isomeric Adamantylideneadamantane/Sesquihomoadamantene Pair (A Combined Experimental And Theoretical Study), Rajendra Rathore, Sergey V. Lindeman, C.-J. Zhu, T. Mori, R. Schleyer, Jay K. Kochi Jan 2002

Steric Hindrance As A Mechanistic Probe For Olefin Reactivity:  Variability Of The Hydrogenic Canopy Over The Isomeric Adamantylideneadamantane/Sesquihomoadamantene Pair (A Combined Experimental And Theoretical Study), Rajendra Rathore, Sergey V. Lindeman, C.-J. Zhu, T. Mori, R. Schleyer, Jay K. Kochi

Chemistry Faculty Research and Publications

Access to each CC face of adamantylideneadamantane (AA) and sesquihomoadamantene (SA) is hindered by the hydrogenic canopy consisting of four β-hydrogens; otherwise, these olefins have quite normal environments. X-ray crystallography and density functional (DFT) calculations show a 0.5 Å larger annular opening in the protective cover of AA than that in SA. This contributes to the remarkable differences in reactivity toward various reagents, not only by limiting access to the olefin site in SA but also by inhibiting reactions which force these hydrogens closer together. Thus, AA is subject to typical olefin-addition reactions with bromine, …

Molecular Structures Of The Metastable Charge-Transfer Complexes Of Benzene (And Toluene) With Bromine As The Pre-Reactive Intermediates In Electrophilic Aromatic Bromination, Alexandr V. Vasilyev, Sergey V. Lindeman, Jay K. Kochi Jan 2002

Molecular Structures Of The Metastable Charge-Transfer Complexes Of Benzene (And Toluene) With Bromine As The Pre-Reactive Intermediates In Electrophilic Aromatic Bromination, Alexandr V. Vasilyev, Sergey V. Lindeman, Jay K. Kochi

Chemistry Faculty Research and Publications

Successful crystallization and X-ray crystallographic analyses of the highly metastable (1∶1) complexes of bromine with benzene and toluene establish the unique (localized) structure B that differs in notable ways from the long-accepted (delocalized) structure A. Furthermore, we demonstrate the (highly structured) charge-transfer complexes [C6H6,Br2] and [CH3C6H5,Br2] to be the pre-reactive intermediates that are converted (via an overall Br+ transfer) to the Wheland intermediates in electrophilic aromatic bromination. The role of the dative ion pairs [C6H6˙+ Br2˙ …

Numerical Studies Of Reactive Polymer Flows In Porous Materials, Honggao Liu Jan 2002

Numerical Studies Of Reactive Polymer Flows In Porous Materials, Honggao Liu

LSU Doctoral Dissertations

This dissertation presents a new numerical model of reactive polymer flow in heterogeneous porous media. A moment representation of the log-normal polymer molecular weight distribution is used to model polymer as a multi-component species. Three leading moments are used to simulate the polymer transport and reaction processes in a two-dimensional porous medium. A new operator splitting technique that allows the moment equations for polymerization to be incorporated into a finite-difference transport model is developed. The novelty of this approach is the use of two different dependent variables (for the transport versus reaction parts of the problem). It is significant from …

Solute Transport In Layered And Heterogeneous Soils, Liuzong Zhou Jan 2002

Solute Transport In Layered And Heterogeneous Soils, Liuzong Zhou

LSU Doctoral Dissertations

Better understanding of transport of dissolved chemicals in soils and aquifers is important to evaluate and remediate contaminated soils and aquifers. Because of the nature of heterogeneity of field porous media, studies on transport processes in non-homogeneous media are necessary. In this study, transport of solutes in layered and heterogeneous media was investigated using numerical approximations. For layered soils, transport properties were assumed homogeneous within individual layers but different between layers. For heterogeneous systems, either a time-dependent or distance-dependent dispersivity was considered to represent the effects of heterogeneity. In a series of simulations of transport in two-layered soils, we found …

Subversive Aspects Of American Musical Theatre, Donald Elgan Whittaker Iii Jan 2002

Subversive Aspects Of American Musical Theatre, Donald Elgan Whittaker Iii

LSU Doctoral Dissertations

Critical discourse regarding musical theatre takes, for the most part, the form of a profound silence, due presumably to a dismissal of the genre as simplistic and insubstantial. Not only have the elements of musical theatre been present in the majority of theatrical history, but many of the greatest theories regarding theatre have included these elements, including Brecht and Wagner. Musicals have also often concerned themselves with the Other, centering and sympathizing him/her in a manner unavailable to non-musical works. The Others that have thus been positioned are often delineated from hegemonic groups which are concretely those in power, but …

Superfetation In Beef Cattle, Joel Andrew Carter Jan 2002

Superfetation In Beef Cattle, Joel Andrew Carter

LSU Doctoral Dissertations

Although superfetation has been reported in cattle and other species, there is considerable skepticism as to its existence due to the lack of clear evidence in these reports. Other explanations such as embryonic diapause or differential growth of twins have been suggested as more accurate descriptions of the cases reported as superfetation. The hypothesis of this study is that if a viable pregnancy can ensure maternal recognition in cattle, an asynchronous embryo can develop in a more chronologically advanced uterine environment. The objective was to produce superfetation by (1) ovulation induction and artificial insemination (AI) of pregnant cows and (2) …

Extraction Of Physically-Realistic Pore Network Properties From Three-Dimensional Synchrotron Microtomography Images Of Unconsolidated Porous Media, Riyadh Ibrahim Al-Raoush Jan 2002

Extraction Of Physically-Realistic Pore Network Properties From Three-Dimensional Synchrotron Microtomography Images Of Unconsolidated Porous Media, Riyadh Ibrahim Al-Raoush

LSU Doctoral Dissertations

Algorithms were implemented to obtain high resolution three-dimensional images using synchrotron microtomography. Morphological algorithms were developed to extract physically-realistic pore-network structure from unconsolidated porous media systems imaged using synchrotron microtomography. The structure can be used to correlate pore-scale phenomena with the pore structure and can also be incorporated into a pore-network model to verify existing models, understand, or predict transport and flow processes and phenomena in complex porous media systems. The algorithms are based on the three-dimensional skeletonization of the pore space in the form of nodes connected to paths. Dilation algorithms were developed to generate inscribed spheres on the …

American Transcendental Vision: Emerson To Chaplin, Bill R. Scalia Jan 2002

American Transcendental Vision: Emerson To Chaplin, Bill R. Scalia

LSU Doctoral Dissertations

Ralph Waldo Emerson's publication of Nature in 1836 began a process of creating a new condition of American thinking, severed from European cultural and intellectual influences. The subsequent lectures The American Scholar and The Divinity School Address furthered this process, calling for an original American literature. Emerson's writing called consistently for poets with the ability to "see" past the material, apparent world to the world of eternal forms, which shaped nature in accordance with a divine moral imperative. Through this connection, man-as-poet would discover God in himself. In short, Emerson effectively transferred divinity from Unitarian doctrine to the individual, thereby …

Numerical Reservoir Characterization Using Dimensionless Scale Numbers With Application In Upscaling, Djuro Novakovic Jan 2002

Numerical Reservoir Characterization Using Dimensionless Scale Numbers With Application In Upscaling, Djuro Novakovic

LSU Doctoral Dissertations

Dimensionless space provides a tool for analyzing the behavior of complex systems described by mathematical relationships. The limited application of dimensionless variables in numerical reservoir simulation and experimental design motivated the development of a complete set of dimensionless scaling groups. Inspectional analysis yielded 8 dimensionless groups completely describing the flow system. Further analysis of fluid interaction reduced the number of dimensionless groups to 7. The newly developed dimensionless equations and groups were used for analytical and numerical reservoir characterization, quantifying the behavior of differential and difference equations employed in fluid flow in three-dimensional porous media. The behavior of the dimensionless …

A Potential Nutraceutical From Leuconostoc Mesenteroides B-742 (Atcc 13146); Production And Properties, Chang-Ho Chung Jan 2002

A Potential Nutraceutical From Leuconostoc Mesenteroides B-742 (Atcc 13146); Production And Properties, Chang-Ho Chung

LSU Doctoral Dissertations

There is an emerging market for functional oligosaccharides for use in foods. Currently, technology for the production of oligosaccharides is limited to extraction from plant sources, acid or enzymatic hydrolysis of polysaccharides or synthesis by transglycosylation reactions. Oligosaccharides also can be produced using a Leuconostoc fermentation and restricting the polymer size by the addition of maltose. Maltose limits the dextransucrase reaction, yielding high concentrations of a-glucooligosaccharides. Branched oligomers produced by this process were found to be readily catabolized by bifidobacteria and lactobacillus but were not readily utilized by either Salmonella sp., or E. coli, pointing toward their use in intestinal …

Reconceiving Curriculum: An Historical Approach, Stephen Shepard Triche Jan 2002

Reconceiving Curriculum: An Historical Approach, Stephen Shepard Triche

LSU Doctoral Dissertations

This dissertation reconceives curriculum through an historical approach that employs Ludwig Wittgenstein’s later philosophy. Curriculum is more than the knowledge taught in school. Curriculum, as I a theorist conceives it, is concerned with the broader intellectual and ideological ways a society thinks about education. Hence, the current school curriculum’s focus on specific learning outcomes offers a limited view of the knowledge fashioned by a society, thereby offering an intellectual and social history that is highly selective. Wittgenstein’s concept of “language-games” offers curricularists a way to re-include some of these stories. The concept of curriculum emerges at the end of the …

Spatial Models Of Hawaiian Streams And Hawaiian Stream Fish Habital, James Elliott Parham Jan 2002

Spatial Models Of Hawaiian Streams And Hawaiian Stream Fish Habital, James Elliott Parham

LSU Doctoral Dissertations

A series of spatially based models of Hawaiian streams and stream fish habitats were developed to aid in the conservation of native fishes. The spatial models focused on the quantification of habitat for native fishes at three levels within a spatial hierarchy. First, at the reach level, the models classified the major geomorphological features of a stream and its watershed to determine the distribution of fish habitat within the different sections of the stream. The distribution of habitat was combined with habitat suitability criteria and the migratory abilities of the native fishes to quantify available habitat and predict expected community …

The Impact Of Gruesome Evidence On Mock Juror Decision Making : The Role Of Evidence Characteristics And Emotional Response, Robert J. Nemeth Jan 2002

The Impact Of Gruesome Evidence On Mock Juror Decision Making : The Role Of Evidence Characteristics And Emotional Response, Robert J. Nemeth

LSU Doctoral Dissertations

Two experiments were conducted to investigate the effects of gruesome evidence on mock jurors? decisions in a simulated capital trial. The first experiment was designed as a replication and extension of Douglas, Lyon, and Ogloff (1997), who found that mock jurors who were presented with gruesome photographic evidence were nearly twice as likely to convict the defendant than participants who did not see the gruesome evidence. In Experiment 1, gruesome evidence was manipulated in two ways: photographic evidence (low gruesome, highly gruesome, or control photographs) and verbal testimony (low gruesome vs. highly gruesome). Neither photographic evidence nor testimony had an …

Analysis Of Diagnostic Testing Of Sustained Casing Pressure In Wells, Rong Xu Jan 2002

Analysis Of Diagnostic Testing Of Sustained Casing Pressure In Wells, Rong Xu

LSU Doctoral Dissertations

Over 8,000 wells in the Gulf of Mexico exhibit sustained casing pressure (SCP). SCP is defined as “any measurable casing pressure that rebuilds after being bled down, attributable to cause(s) other than artificially applied pressures or temperature fluctuations in the well”. The Minerals Management Service (MMS) regulations consider SCP hazardous and, in principle, require its elimination. In some cases the agency may allow continuing production at a well with SCP by granting a temporary “departure” permit. The departure permits are based on diagnostic tests involving pressure bleed-down through a 0.5-inch needle valve followed by closing the valve and recording pressure …

Synthesis And Properties Of Novel Macrocycles And Related Chromophoric Benzenoid Compounds, Jorge O. Escobedo Cordova Jan 2002

Synthesis And Properties Of Novel Macrocycles And Related Chromophoric Benzenoid Compounds, Jorge O. Escobedo Cordova

LSU Doctoral Dissertations

The synthesis and properties of some macrocyclic compounds of interest are presented. Resorcinarenes with functionalized conjugated rigid rods made of oligo-p-phenylenes would lead to an entirely new class of functional, soluble, well-defined architectures impacting a variety of multidisciplinary research efforts. The general synthetic design described in this document could be readly extrapolated to include other electronic systems such as heteroaromatics and polyenes. An extensive collaborative study of chromophore formation in resorcinarene solutions is also described here. The study reveals that upon oxidation, the reversible conversion to acyclic precursors occur first, and then these precursors undergo oxidation to quinoid-type compounds (xanthenes). …

Thermal Rheological Analysis Of Cure Process Of Epoxy Prepreg, Liangfeng Sun

LSU Doctoral Dissertations

The cure process of epoxy prepreg used as composite pipe joints was studied by means of differential scanning calorimetry (DSC), Bohlin Rheometer and other techniques. Isothermal DSC measurements were conducted between 110 and 220 oC, at 10 oC intervals. The results show that the complete cure reaction could be achieved at oC. The isothermal cure process was simulated with the four-parameter autocatalytic model. Except in the late stage of cure reaction, the model agrees well with the experimental data, especially at high temperatures. To account for the effect of diffusion on the cure rate, a diffusion factor was introduced into …

Hydrodynamics And Freshwater Diversion Within Barataria Basin, Dongho Park Jan 2002

Hydrodynamics And Freshwater Diversion Within Barataria Basin, Dongho Park

LSU Doctoral Dissertations

In order to understand the physical processes in the Barataria estuary, a previously developed two-dimensional, depth-integrated hydrodynamic model is applied to simulate estuarine processes. The equations for conservation of mass and momentum predict specific physical processes when forced by tidal and salinity variations at the open boundaries, wind forcing patterns, precipitation and evaporation over the model domain, and freshwater runoff as point sources. This study is focused on examining the impact of freshwater dispersion from the freshwater sources. Thus, a hydrologic model was developed to estimate runoff. Furthermore grid size was reduced, a new advective code added, and baroclinic effects …

Spirit Matter(S): Post-Dualistic Representations Of Spirituality In Fiction By Walker Percy, Toni Morrison And Gloria Naylor, Likourgos James Vassiliou

LSU Doctoral Dissertations

Spirit Matter(s): Post-Dualism Representations of Spirituality in Fiction by Walker Percy, Toni Morrison and Gloria Naylor, examines the ways in which these authors have presented spirituality in The Moviegoer, Song of Solomon, and Mama Day respectively. In these works, spirituality is a need for connection among humans in this world, rather than a notion that points to dualistic views of the spiritual and the material as two different realms. Through this perspective on spirituality as a reality of the physical world, the political and socio-economic problems of the world are not—nor can they be—set aside in favor of the spiritual …

Peroxynitrite-Mediated Oxidations: Nitration And Nitrosation, Rachel Bolzan Jan 2002

Peroxynitrite-Mediated Oxidations: Nitration And Nitrosation, Rachel Bolzan

LSU Doctoral Dissertations

Using a direct ultraviolet second-derivative spectroscopy method, three peroxynitrite preparative methods were investigated for the nitrite and nitrate present either as impurities or produced during peroxynitrite decomposition: (I) ozonation of azide, reaction of hydrogen peroxide with (II) isoamyl nitrite and (III) nitrous acid. The oxidation of morpholine by peroxynitrite in the presence and absence of added carbonate gives N-nitromorpholine and N-nitrosomorpholine. Nitration and nitrosation of morpholine are catalyzed by low levels of CO2; however, excess CO2 dramatically reduces the yields of nitrosation but not nitration, and the combined yields of the products are about the same under …

The Combined Effects Of Salinity And Sulfide On The Growth And Physiology Of The Freshwater Marsh Plant Pancium Hemitomon J.A. Schultes, James Wesley Pahl Jan 2002

The Combined Effects Of Salinity And Sulfide On The Growth And Physiology Of The Freshwater Marsh Plant Pancium Hemitomon J.A. Schultes, James Wesley Pahl

LSU Doctoral Dissertations

Vegetative response to saltwater intrusion into coastal freshwater wetlands is governed by the combined effects of increased salinity and porewater sulfide concentrations. I conducted a series of experiments to address the primary hypothesis that growth of Panicum hemitomon is adversely affected by an interaction between salinity and sulfide stresses associated with saltwater intrusion, and the mechanisms for decreased growth are alterations in the metabolic and morphological adaptations needed for a plant to survive in a flooded environment. I exposed marsh sods to a factorial treatment arrangement of three salinities (0, 2, and 4 ppt) and three porewater sulfide concentrations (0, …
