George Price Boyce And The Consolation Of Landscape, Julia Chandler L'Enfant

LSU Historical Dissertations and Theses

George Price Boyce (1826-1897) is little known today except by his diaries, which chronicle his association with the Pre-Raphaelite circle in London from 1851 to 1875. Yet in his own day Boyce was widely admired for his watercolor landscapes, and after 1864 was a leading member of the select Royal Water-Colour Society. His landscapes were thought to have a special, even eccentric quality, particularly his work from about 1859 to 1870, generally acknowledged to be his best.

Critics and art historians who take note of Boyce today almost always link him with the Pre-Raphaelite movement. This thesis, however, seeks to …

Arcadia Disjointed: Confrontations With Texts, Polemical, Utopian, And Picaresque., Deborah Ann Jacobs

LSU Historical Dissertations and Theses

Beginning with the historical example provided by the extended text of the Popish Plot, that is, by the polemical press battle which raged during this major threat to Charles II's Restoration government, I identify what I term a narrator/narrative disjunction. The narrator/narrative disjunction occurs when the narrator or teller relates one story, while the narrative he or she relates suggests or strongly intimates that the narrator should be adjudged less than reliable. In the course of this exploration, I read several Tory polemical texts on the Popish Plot, including Dryden's Absalom and Achitophel, not as literary works, but rather as …

Some Results On Minors For Graphs And Matroids., Lawrence Alan Wargo

LSU Historical Dissertations and Theses

This dissertation solves some problems relating to the theory of graphs. The first type of problem considered concerns the structure of various classes of graphs which arise naturally from outerplanar graphs. These problems are motivated by Chartrand and Harary's well-known characterization of outerplanar graphs. This theorem states that K$\sb4$ and K$\sb{2,3}$ are the only non-outerplanar graphs for which both G$\\$e, the deletion of the edge e from the graph G, and G/e, the contraction of the edge e, are outerplanar for all edges e of G. Following Gubser's characterization of almost-planar graphs, we begin our study of graphs related to …

Structure Of Synthetic Oligosaccharides By Tandem Mass Spectrometry., Eunsun Yoo Yoon

LSU Historical Dissertations and Theses

Certain linkage positions in oligosaccharides can be discerned by collision-activated dissociation mass spectrometry (MS-CID-MS), rationalized by molecular modeling. The first part of this dissertation shows that linkage-specific daughter ion spectra of synthetic amino-sugar containing oligosaccharides can be obtained from several alkylated derivatives such as sodiated, potassiated, ammoniated and lithiated derivatives. Methylated derivatives of the synthetic oligosaccharides give more useful linkage discernment product-ions, including a 3-linkage specific ion. A novel approach of relating daughter ion to parent ion ratios and collision energy is described and is predictive of linkage position in the first set of six oligosaccharides used. In the second …

Ultrafast Measurement Of Chemical Dynamics In The Condensed Phase Using Transient Vibrational Spectroscopy., Xiaobing Xu

LSU Historical Dissertations and Theses

Geminate recombination and vibrational energy relaxation of iodine in the condensed phase are investigated using picosecond transient Raman spectroscopy. The advantages of transient Raman in measuring vibrational energy relaxation and separating different reaction dynamics are demonstrated in this dissertation. Using transient Raman spectroscopy we have for the first time directly observed geminate recombination and vibrational energy relaxation of I$\sb2$ on both X and $A\sp\prime$ $\sp3\Pi\sb{2u}$ states. For the X state, energy relaxation from vibrational levels ranging from $\upsilon$ = 52 to $\upsilon$ = 1 have been observed. These levels correspond to absolute energies of 9,300 to 210 cm$\sp{-1}$ above the …

Voices Of The Self In Daniel Defoe's Fiction: An Alternative Marxist Approach., Zaixin Zhang

LSU Historical Dissertations and Theses

The alternative Marxist approach to literary criticism in the present study consists of three "vocal" modes of interpretation: the public voice, the private voice, and the homeless voice of the self. The public voice represents authorial visions of the ideological real projected by dominant ideology that covers up the "objective" real, while the private voice corresponds to the authorial conscious or unconscious insertion into radical ideology that turns the "objective" real into the ideological real. However, the homeless voice of the self obliterates any ties with history and authorial ideology. A personification of the Marxist "particular interest" of the self, …

Biological Treatment Of Hazardous Waste Sludges In Suspended Growth Systems For Removal Of Benzo(A)Pyrene And Other Polynuclear Aromatics., Robert E. Marks

LSU Historical Dissertations and Theses

The scope of this research project was to develop a bioremediation process for accelerated oxidation of bioresistant hazardous waste sludges in continuous flow sludge reactors. Benzo(a)pyrene (BaP) was selected as the target compound due its strong bioresistance, highly carcinogenic nature, extremely low aqueous solubility, and extremely low allowable release limits for land disposal. BaP is often a major hazardous organic component in many hazardous waste impoundments when source wastes have originated from either petroleum refining or associated petrochemical facilities. There is evidence that the biodegradation rate of high molecular weight polynuclear aromatic hydrocarbons (PNA's) is the rate limiting step in …

The Form And Function Of Constructed Dialogue In Reported Discourse., Terrie Dawn Mathis

LSU Historical Dissertations and Theses

In this study of constructed dialogue in natural conversations involving four American women, attention is drawn to how reporting speakers make use of different quotative forms to introduce utterances represented with direct speech forms. There is an attempt to account for the functions of such quotative forms in terms of discourse structure and the interpersonal relationships of the participants. In one closely-examined narrative, the present tense forms of several quotatives (is, says, goes, and be like) are used to introduce constructed dialogue which seems to be that part of the narrative that the speaker intends to foreground, while the past …

"Spades Players" And "Senators": An Ethnography Of Black Subcultures In A Community College., Anthony Louis Molina Sr

LSU Historical Dissertations and Theses

This ethnographic study of Black community college students, in a predominantly white community college, took place over a three-year period and focused on two groups. One group, the spades players, neglected their studies in favor of the card game spades, which they made the central activity of their family-like collective in the student commons. The other group, Black senators in the Student Government Association, were academic achievers who performed service to the college. By immersion into both cultures, the researcher gained the confidence of individual students in both groups, interviewed them in various settings, and looked for reasons behind the …

Genotype X Environment Interaction For Growth And Reproductive Traits In Beef Cattle., Louis Munyakazi

LSU Historical Dissertations and Theses

Data on eight different two breed combinations of calves produced in two locations (Louisiana and Nebraska) were analyzed to determine the magnitude of genotype x location interactions for gestation length (GESTLEN), birth weight (BWT), pre-weaning average daily gain (ADG) and weaning weight (WWT). Sire breed (SB), sire/SB and cow breed (CB) interactions with location (LOC) were the primary sources of variation of interest in the analysis of variance. The SB x LOC interaction was significant for all traits whereas the CB x LOC interaction was important only for ADG. The sire/SB x LOC interaction accounted for a significant amount of …

Efficient Data Structures And Algorithms For Scientific Computations., Soon Cheol Park

LSU Historical Dissertations and Theses

Large-scale numerically intensive scientific applications can require tremendous amounts of computer time and space. Two general methods are presented for reducing the computer resources required in scientific computing. The first is a numerical database system which is built on a space and time optimal data structure called a weighted search tree and that allows for the storage and retrieval of valuable intermediate information so costly redundant calculations can be avoided. The second is a matrix algorithm based on a new space optimal representation of sparse matrices that for typical scientific applications can be expected to dramatically decrease the cost of …

Organic Matter Variation Within Depositional Sequences: Stratigraphic Significance And Implication To Petroleum Source Rock Prediction., Mark Alan Pasley

LSU Historical Dissertations and Theses

Study of Eocene-Oligocene sediments in Alabama and Upper Cretaceous strata in New Mexico shows that organic facies deposited on the shelf change noticeably at surfaces associated with transgression of the shoreline. Organic matter in sediments below transgressive surfaces is dominated by well preserved terrestrial organic matter (phytoclasts) whereas sediments deposited on the shelf during transgression contain sparse, highly degraded phytoclasts. Shelf deposits associated with transgressions generally contain more hydrogen-rich organic matter than those deposited during regression. Sediments associated with starvation surfaces contain abundant amorphous nonstructured protistoclasts and rare, highly degraded phytoclasts. Well preserved phytoclasts increase in abundance in sediments overlying …

Factors Controlling The Distribution Of The Black Mangrove, Avicennia Germinans L., In A Louisiana Mangal/Salt Marsh Community., Charles Stuart Patterson

LSU Historical Dissertations and Theses

Mangroves are intertidal, halophytic trees limited to the tropics and subtropics because they are not cold-tolerant. In coastal Louisiana (29$\sp\circ$ N latitude), the black mangrove, Avicennia germinans, is the only mangrove found because Avicennia is the most cold-tolerant of mangrove genera. Avicennia intergrades with salt marsh cordgrass, Spartina alterniflora, with 3 observed zones: an Avicennia zone, a transition zone, containing both Avicennia and Spartina, and a Spartina zone. The purpose of this dissertation was to determine why A. germinans does not occur in the Spartina zone within a mangal/salt marsh ecotone. Three studies investigated the following zone differences in: (1) …

The Alkaloids Of Erythrina: Clonal Evaluation And Metabolic Fate., Lori Denise Payne

LSU Historical Dissertations and Theses

The foliage of thirteen genetic clones of the nitrogen-fixing trees Erythrina berteroana, E. poeppigiana and E. costarricensis growing under similar environmental conditions in the Latin American Nitrogen Fixing Tree Arboretum, CATIE, Turrialba, Costa Rica, was evaluated by gas chromatography/mass spectrometry for toxic alkaloid content. The major alkaloid identified was $\beta$-erythroidine, a naturally derived drug used in the 1950s and 1960s as a neuromuscular blocking agent in surgery and electroshock treatments. Other alkaloids identified were $\alpha$-erythroidine, erybidine, erythraline, erysodine, oxo-$\beta$-erythroidine and several previously undescribed compounds. There was a difference of more than two orders of magnitude in the $\beta$-erythroidine concentration between …

Modeling The Effect Of Shale Heterogeneities On Hazardous Waste Transport In Deep Well Disposal Systems., Seung-Whee Rhee

LSU Historical Dissertations and Theses

The transport of hazardous wastes in heterogeneous confining layers was evaluated using numerical simulations. The expected configuration of the confining layers was defined by Monte Carlo techniques assuming a binary random structure composed of pure sand and pure shale zones. Flow and solute transport in the generated configuration was determined via a finite element model. The effective permeability under saturated steady-state flow was dominated by shale permeability for higher shale fractions ($>$0.65) and by sand permeability for lower shale fraction ($<$0.4). The results agreed well with the numerical result of Desbarats (1987) and the analytical results of Dagan (1979). The effective vertical permeabilities were found to be dependent on shale size and anisotropy. Application of the techniques to a well in Jefferson Parish, Louisiana suggested that a mean advective penetration into confining layer using the injection pressure as an upper bound to the driving pressure was only 3m over 10,000 years. Transport calculations assuming a constant pressure driving force over 10,000 years suggested solute transport was controlled by hydrodynamic dispersion (dispersion + diffusion) rather than advection for higher shale fractions. Transport calculations assuming active injection for only the first 100 years suggested solute transport was controlled by diffusion for higher shale fraction. Buoyancy effects associated with salinity and temperature variations were negligible for solute transport through confining layers with a shale permeability less than 0.01 md. The results of solute transport of hazardous wastes in heterogeneous confining layers suggested that confining layers greater than 300 ft in thickness with shale fractions of greater than 0.65 and shale permeabilities of less than 0.01 md would be expected to contain injected wastes for 10,000 years.

Examination Of Potato Virus X Subgenomic Rnas: Their Number, Their Coding Properties, And Their Possible Encapsidation., Mary A. Price

LSU Historical Dissertations and Theses

Potato Virus X is the type member of the Potexvirus group. It is a flexuous rod containing a single-stranded, positive-sense RNA. Previous studies have shown that during infection Potato Virus X synthesizes subgenomic RNAs to express internal cistrons. These studies demonstrated that six subgenomic RNAs could be detected in total RNA extracts from PVX-infected tissue; however, only four internal ORFs are predicted within the genomic RNA. Furthermore, two particle size populations were detected, one containing genomic RNA and one containing the coat protein mRNA. In the present investigation experiments were designed to examine PVX-encoded subgenomic RNAs with regard to their …

Atoms And Di-Atoms In Intense Laser Fields., Muhammad Raza Saeed

LSU Historical Dissertations and Theses

A series of experimental studies was carried out on diatomic molecules to understand how they interact with intense laser fields. These studies have mainly consisted of multiple photon excitation, ionization and dissociation of hydrogen, oxygen, and chlorine molecules using time of flight electron and ion spectroscopy. I took advantage of the similarities and differences in the molecular structure of these molecules in order to investigate whether different molecules interact differently with the applied fields. Clear experimental evidence of molecular Bond Softening as an intensity dependent variation in the vibrational distribution of molecular ions is being reported for the first time …

Factors Responsible For The Differential Growth Of Brucella Abortus In Bovine Trophoblasts., Luis Ernesto Samartino

LSU Historical Dissertations and Theses

The interactions of bovine chorionic membrane explants (CAMs) as well as three different bovine trophoblastic cell lines with Brucella abortus were evaluated. The ability of B. abortus to infect and grow within the cells of these CAMs and within these cell lines was measured. In addition, prostanoid and hormone production by the trophoblastic cells after infection with B. abortus was measured. Internalization of B. abortus within the cells of CAMs derived from placentas from both 3-month-gravid cows and 7-month-gravid cows was similar. By 24 hours post-inoculation B. abortus replication in 7-months-derived CAMs was significantly greater than the replication occurring in …

The purpose of this ethnographically informed, autobiographic case study is to examine the relational and contradictory dynamics of an urban southern school district's systemic process of educational reform from multicultural perspectives. The case study examines the rules, roles and relationships of key change agents and stakeholders as they define education from multicultural perspectives in the process of change. The research further examines the developmental processes necessary to transform the existing curriculum …

Forged Ties: The 'Comitatus' And Anglo -Saxon Poetry., Leslie Ann Stratyner

LSU Historical Dissertations and Theses

The focus of this study is the illumination of the most unchanging and consistent aspect of Anglo-Saxon poetry: the poetic representation of the ethos of the warrior band. The ideals of the comitatus offer a contributing, if not controlling, structure to nearly the entire corpus of Anglo-Saxon poetry. That warband could attain no finer poetic representation than Beowulf and "The Battle of Maldon," which, in presenting not only positive but negative models of behavior, best exemplify the ideals of the comitatus as embodied in Anglo-Saxon verse. Chapter 1 examines the institutions and practices of that masculine circle as illustrated in …

The Clan Of Toil: Piney Woods Labor Relations In The Trans-Mississippi South, 1880-1920. (Volumes I-Iii)., John Reed Tarver

LSU Historical Dissertations and Theses

Lumber boomed in the Reconstructed South, an industrial binge that, by 1920, changed the landscape, first removing the forest then replacing its subsistence economy with consumerism. Men with money made fortunes in lumber. West of the Mississippi and south of the Missouri, it became a bonanza by 1880. Within these boundaries, black and white farmers and field hands sought "public work" in sawmills and log fronts. Most were unskilled. Steam power changed their lives, although all did not respond alike. They kept their folk ways, consistent with the new industry, despite their bondage to machines. Although most workers voluntarily entered …

In Vitro Culture Of Bovine Uterine And Oviduct Epithelial Cells., John Kevin Thibodeaux

LSU Historical Dissertations and Theses

A reliable procedure was developed to harvest purified populations of bovine uterine epithelial cells from the luminal endometrium that allowed cells to be maintained in vitro for multiple subpassages. This method allowed adequate numbers of cells for in vitro culture studies to evaluate uterine secretion rates, uterine-embryo interactions and a new embryo co-culture system. In a second study, cells were isolated from the uterus and oviducts collected from cattle on day of estrus, on d 4 to 6, d 8 to 10 and d 14 to 16 of the cycle to monitor growth and development following incubation in vitro. The …

Problem Behaviors Associated With Sociometric Status In An Adolescent Population., Glenda C. Thorne

LSU Historical Dissertations and Theses

The purpose of the present study was to investigate the usefulness of the classification system developed by Coie and his colleagues (1982) with an adolescent population by examining the relationship between sociometric status and psychopathology. Five hundred thirty-one seventh- through ninth-grade students participated in the study. Following the Coie et al. (1982) procedure, children were identified as either popular, rejected, neglected, controversial, or average. The basis for status group membership was scores adolescents received on positive and negative peer nominations. Four social status variables were derived from these measures: (a) liked most peer nomination scores, (b) liked least peer nomination …

Systematics Of Rudbeckia Subgenera Macrocline And Laciniata (Asteraceae: Heliantheae: Rudbeckiinae)., Patricia Blackwell Cox

LSU Historical Dissertations and Theses

Rudbeckia, a North American genus, consists of approximately 21 species of annual and perennial herbs. Rudbeckia is separated into three subgenera (i.e. Laciniata (n = 19 (18)), Macrocline (n = 18) and Rudbeckia (n = 19)) based on morphological, cytological, chemical, and phylogenetic data. The present research includes a systematic study of subgenera Laciniata and Macrocline. Also included is a phylogenetic analysis of the coneflower genera (Dracopis, Echinacea, Ratibida, and Rudbeckia).

Genetics Of Resistance To Preharvest Aflatoxin Accumulation In Maize Containing The Lfy Gene., Daniel Preston Gorman

LSU Historical Dissertations and Theses

Preharvest infection of maize (Zea mays L.) grain by Aspergillus flavus Link ex Fries and subsequent aflatoxin contamination is a serious problem, especially in the southeastern USA. Studies on the genetics of resistance to aflatoxin contamination in maize are quite limited, but a better understanding of this aspect is needed for developing resistant germplasm. The objective of the first field study was to determine the genetics of resistance to aflatoxin contamination in maize possessing the leafy (Lfy) gene. Seven Lfy synthetic genotypes were crossed in a diallel fashion, and the resulting 21 single crosses were evaluated for aflatoxin contamination in …

Quantitation Of Phenolic Acids And Effect Of Controlled Atmosphere Storage On Peach Fruit Quality., Ahmed Fathallah El-Shiekh

LSU Historical Dissertations and Theses

Total and individual phenolic acids in firm-ripe fruit of ten different peach (Prunus persica Batsch.) genotypes were analyzed by spectrophotometry and high performance liquid schrmoatography (HPLC) and related to internal browning potential. A comparison of phenolic acid separation was made between five different column types. A Lichrosorb RP-18 column provided the best separation of the major phenolic acids in peach fruit mesocarp tissue. Quinic was the predominant phenolic acid, followed in concentration by gentisic, catechin, chlorogenic, and syringic acids. Quantities differed between genotypes. The genotypes with the highest internal browning potential contained the highest concentration of chlorogenic acid, gentisic acid, …

Stereoelectronics Of Carboxylate-Imidazolium Hydrogen Bonds In Models Of The Aspartate-Histidine Couple In Serine Proteases., Nabeel Abdel Raouf Nabulsi

LSU Historical Dissertations and Theses

The geometry of the carboxylate-imidazolium hydrogen bond in the crystalline state and the effect of microenvironment are investigated in models of the aspartate-histidine (Asp-His) couple. Synthetic methods leading to the preparation of intramolecular models, possessing syn and anti-oriented hydrogen bonds, also are described. A single-pot procedure has been developed for converting phenoxyacetonitriles into their respective benzimidazole derivative in higher yields than the traditional two step procedure. An efficient single-pot procedure also has been developed for converting benzofuran to its acetylene derivative, 2-acetoxyphenylacetylene. This method involves in situ acetylation of the unstable phenol intermediate. Nine intermolecular imidazolium-benzoate couples have been prepared …

J. S. Bach's Chaconne In D Minor: An Examination Of Three Arrangements For Piano Solo., Jeffery Mark Pruett

LSU Historical Dissertations and Theses

The chaconne from the Second Partita for Solo Violin by Johann Sebastian Bach is one of the most often arranged compositions in the history of music. In the century following the first publication in 1802 of Bach's six sonatas and partitas for solo violin, the chaconne was performed in arrangements and transcriptions almost as diverse as the composers whom it inspired. From the years 1879 and 1893, respectively, came the most famous arrangements--those by Johannes Brahms and Ferruccio Busoni (both for solo piano). Larry Sitsky, writing of works based on the chaconne apart from those for solo instruments, has referred …

Three Essays On Sampling Techniques: Small Sample Performances Of Estimators And Predictors., Parisun Chantanahom

LSU Historical Dissertations and Theses

The dissertation addresses the issues of small sample properties of estimators and predictors. Economic analysis usually relies on the asymptotic properties of estimators and predictors which may not be the same as their asymptotic counterparts. Furthermore, some biased estimators and predictors used in economic studies have certain asymptotic properties which are not fully understood. Consequently, sampling techniques are used to explore the small sample properties and construct confidence intervals for predictors and estimators. In the dissertation, first, Monte Carlo experiments are used to find an appropriate estimation procedure for a system of simultaneous equations which involves a latent endogenous variable. …
