Modelling Of Passive Contaminant Transport In River Sediments., Susan Anne Savant-Malhiet

LSU Historical Dissertations and Theses

Contaminant transport from riverine sediments was investigated via physical and mathematical models. Due to its remote nature, there exists a lack of understanding of transport mechanisms and rates at the sediment-water interface of rivers. This dissertation is focused on evaluation of potential abiotic transport processes which affect the movement of contaminants across this sediment-water interface. Only non-dispersive transport of passive contaminants was considered allowing the research to focus on the movement of the sediment pore water which carries the contaminants. The abiotic processes studied include the advection by flow of sediment pore water and the movement and turnover of sediment …

A Field Method For Assessing Borehole Friction For Directional Well Casing, Eric E. Maidla, Andrew K. Wojtanowicz

Faculty Publications

A field procedure to evaluate the borehole friction factor between a pipe string and a borehole was developed. The primary concern of this research was to investigate and mathematically describe the drag associated with casing runs in directional wells through the use of the two-dimensional approach. The borehole friction factor was found, through an iterative procedure, by matching the calculated hook load to the measured one at the surface. The borehole friction factor was calculated as the unique value for the match. This study shows the necessary precision requirements for the hook load measurement instrumentation and presents three different types …

Response Of Soybean Growth And Dinitrogen-Fixing Ability To Insect-Induced Defoliation., Maurice Blake Layton Jr

LSU Historical Dissertations and Theses

A series of greenhouse experiments was conducted to investigate the effects of insect-induced defoliation on growth and N$\sb2$-fixing ability of soybean. This research had three major objectives: (1) to examine the effects of different levels of defoliation, (2) to determine the impact of progressive defoliation, and (3) to study the ability of soybeans to recover following defoliation. All experiments were conducted in a similar manner. Larvae of the soybean looper, Pseudoplusia includens (Walker), were used to defoliate soybeans in the vegetative stage of development and the acetylene-ethylene reduction assay was used to provide an indirect measure of N$\sb2$-fixing ability of …

A History And Daybook Of The English Language Theatre In New Orleans During The Civil War. (Volumes I And Ii)., Paula June Thompson

LSU Historical Dissertations and Theses

This study investigates the theatrical activity in New Orleans between 1860 and 1865 and provides a daybook including all recorded performances in the city during this period. Many active theatres existed in New Orleans prior to 1860. Three theatres, the St. Charles, the Varieties, and the Academy of Music dominated professional English-language dramatic offerings. They brought in the most renowned performers of the period and presented lavish dramatic productions, minstrel shows, circuses and concerts. This study explores the impact of the war on the theatrical activity of these three theatres and attempts to chronicle the adjustments necessary to continue operation. …

Three Essays On The Welfare Effects Of Factor Immobility And Price Uncertainty For A Country Experiencing Growth, Entering A Customs Union And Giving Or Receiving A Unilateral Transfer., Carolyn Margaret Landry

LSU Historical Dissertations and Theses

This dissertation presents an intertemporal model with two degrees of endogenously determined labor mobility: complete immobility in the short run and partial mobility in the long run. It examines the impact on welfare when, in response to a change in an exogenous variable, the nation adjusts its output ratio. The movement of factors between sectors is necessary but in the case of labor, that does not take place at first because of labor's slowness in responding to a developing wage differential. The consequent contraction of the product transformation curve is welfare reducing. Uncertainty about the future terms of trade is …

Following the history of the development of the curricula, influences of major music education trends upon the curricula are discussed. The history of the development of the curricula is organized by periods: the organizational years of the Southern …

Ultrastructural Studies Of Cell Membrane-Associated Events In Early And Late Stages Of Bovine Coronavirus Replication., Harold Ross Payne

LSU Historical Dissertations and Theses

The early events in the infection of human rectal tumor cells by bovine coronavirus were investigated by immunoelectron microscopy and by studies with lysosomotropic weak bases. Virus particles labeled with colloidal gold were endocytosed by synchronously infected cells and accumulated in vacuoles that resembled secondary lysosomes. Sites of fusion between the virus envelope and the plasmalemma were observed but fusion events along intracellular membranes were not found. Exposure of cells to ammonium chloride or to mythylamine during the first hour of infection had little inhibitory effect on the production of infectious virus. Chloroquine treatments were inhibitory but this effect was …

A Judicial Decision Under Pressure: A Dramaturgical Analysis Of The Rosenberg Case., Kenneth C. Petress

LSU Historical Dissertations and Theses

This study examines the 1951 death sentences imposed upon Ethel and Julius Rosenberg by Judge Irving R. Kaufman. This study's focus is discovering how these sentences came to be, rhetorically. The study employs the dramatistic pentad suggested by Kenneth Burke. The scene is seen as the dominant, driving force behind the judge's sentences. The scene is labeled as "betrayal"; the name betrayal resulting from: (1) the Cold War; (2) McCarthyism; (3) the Korean War; and (4) other domestic post-World War II problems. The analysis pictures the American government using the Rosenbergs as scapegoats to symbolically cleanse away betrayal images. Thus, …

A Molecular Characterization Of An Escherichia Coli Restriction System Specific For 5-Methylcytosine-Containing Dna., Troy Kevin Ross

LSU Historical Dissertations and Theses

The McrB restriction system in Escherichia coli K-12 is responsible for sequence-specific recognition and inactivation of DNA containing 5-methylcytosine. A derivative of plasmid pUC8 with a 5.5-kilobase pair BglII-EcoRI restriction fragment from the E. coli K-12 chromosome, imparted the wild-type phenotype to the McrB$\sp-$ strain K802. The limits of the McrB region within this DNA fragment were defined by deleting portions of the 5.5-kb insert and assaying for McrB restriction of M.AluI-methylated DNA. Analyses of polypeptides encoded by the McrB region using a maxicell strain revealed that at least three proteins, having molecular weights of approximately 51,000, 39,000, and 33,000, …

On The Thermodynamics Of Quantum-Electrodynamic Frequency Shifts, G. W. Ford, J. T. Lewis, R. F. O'Connell

Faculty Publications

A paper by Barton (ibid., vol.20, p.879, 1987) comments on some of Ford et al.'s recent work in this general area and takes issue with some of their conclusions. Ford et al. point out that Barton's reinterpretation of his own previous work actually serves to support their conclusions. In particular, he is making extensive use of thermodynamic concepts (free energy, thermodynamic perturbation theory, . . .) which were introduced for the first time into this area in the papers by Ford et al.

Backfilling Canals To Mitigate Wetland Dredging In Louisiana Coastal Marshes, Christopher Neill, R. Eugene Turner

Faculty Publications

Returning canal spoil banks into canals, or backfilling, is used in Louisiana marshes to mitigate damage caused by dredging for oil and gas extraction. We evaluated 33 canals backfilled through July 1984 to assess the success of habitat restoration. We determined restoration success by examining canal depth, vegetation recolonization, and regraded spoil bank soils after backfilling. Restoration success depended on: marsh type, canal location, canal age, marsh soil characteristics, the presence or absence of a plug at the canal mouth, whether mitigation was on- or off-site, and dredge operator performance.

Backfilling reduced median canal depth from 2.4 to 1.1 m, …

Free Energy For Harmonically Bound Fermions In A Magnetic Field, Lipo Wang, R. F. O'Connell

Faculty Publications

An analytic expression is obtained for the free energy of fermions bound in an anisotropic harmonic potential in the presence of an arbitrary magnetic field, at a finite temperature. The specific heat and the magnetic moment are readily calculated. The results consist of two parts, a steady part and an oscillatory one. The latter is similar to the well known de Haas-van Alphen oscillation, but persists in the absence of a magnetic field. Application of the results to the nuclear shell model and surface effects of solids are briefly discussed. © 1987, IOP Publishing Ltd.

Liquid Crystals From Poly(4,4'-Methoxybiphenylyl Methacrylate)., R. Duran, D. Guillon, Ph Gramain, A. Skoulios

Faculty Publications

Side-chain liquid crystalline poly(4,4'-biphenylyl methacrylate) was studied by x-ray diffraction. Three smectic phases were described using a ribbon-like structural model for the polymer chain. In the smectic S//P phase, ribbons lie flat on their sides to form layers with a spacing equal to the thickness of the ribbons. In the smectic S//A phase, the ribbons stand upright giving layers with a thickness corresponding to the length of one extended monomeric unit. In the ordered smectic S//O phase, the layer thickness also corresponds to one extended repeat unit, and the pendant groups are arranged according to a two-dimensional oblique lattice. The …

Effect Of Seasonal Changes In Leydig Cell Number On The Volume Of Smooth Endoplasmic Reticulum In Leydig Cells And Intratesticular Testosterone Content In Stallions, L. Johnson, D. L. Thompson

Faculty Publications

Testes from 47 adult (4-20 years) stallions obtained in November-January (non-breeding season) and 41 adult stallions obtained in May-July (breeding season) were perfused with glutaraldehyde, placed in osmium and embedded in Epon 812. Percentage Leydig cell cytoplasm or nuclei in the testis was determined by point counting of 0.5 μm sections under bright-field microscopy. Testes from 6 randomly selected horses per season were processed for electron microscopy. The volume (ml) of SER/testis was calculated from the % SER in the cytoplasm % Leydig cell cytoplasm, and parenchymal volume. Number of Leydig cells was calculated from the % nuclei, parenchymal volume, …

Production And Evaluation Of Antisera And Monoclonal Antibodies Directed Against The Serovar-Specific Lipopolysaccharide Antigens Of Vibrio Cholerae., Linda Benton Adams

LSU Historical Dissertations and Theses

Vibrio cholerae is typed serologically on the basis of somatic O-antigens. The serovar-specific antigens A, B, and C of V. cholerae O1 are located in the polysaccharide (PS) moiety of the lipopolysaccharide (LPS) in the cell wall, but the exact structure and composition of these antigens are unknown. Presently, V. cholerae non-O1 serovars are differentiated serologically by two independent typing systems. Each system utilizes whole cell vaccines which result in typing sera containing serovar-specific, anti-PS activity and non-specific, cross-reacting activities. Serovar-specific anti-PS sera were produced in rabbits immunized with PS extracted from selected vaccine strains of V. cholerae O1 and …

Determinants Of Joint Venture Performance: A Study Of International Joint Ventures In The United States (Japan, Europe)., Winston Kwashie Awadzi

LSU Historical Dissertations and Theses

This study focuses on: (1) the motivations for international joint venture (IJV) formation in the United States; (2) the bases and outcomes of bargaining between partners; and (3) the relationship between the outcomes of bargaining and joint venture performance. Forty U.S.-based joint ventures formed by U.S. firms with Japanese (22) and European (18) partners were studied. These IJVs operated in the manufacturing sector of the economy. The results of the study show that both U.S. government regulations and/or attitudes (GRA) and business-related factors were significant motivators for IJV formation. However, business-related factors were much stronger motivators than GRA for the …

A Radical Republican In The United States Senate: The Antislavery Speaking Of Benjamin Franklin Wade (Ohio)., Daniel Stewart Brown Jr

The study …

Crime And Punishment In The Royal Navy: Discipline On The Leeward Islands Station, 1784-1812 (England)., John D. Byrn Jr

LSU Historical Dissertations and Theses

This dissertation is based primarily on the manuscript sources pertaining to the Leeward Islands station between 1784 and 1812 found in the Public Record Office. Its thesis is quite simple: Discipline in the Royal Navy in the age of sail was maintained in much the same fashion that law and order was enforced in the localities of eighteenth-century England. In short, justice afloat was administered according to the principles and practices used in the system of criminal law ashore.

An Assessment Of Africanized Honey Bees (Apis Mellifera L.) As Crop Pollinators., Robert George Danka

LSU Historical Dissertations and Theses

Neotropical Africanized honey bees are predicted to replace European bees and become the primary agricultural pollinators in the southern and coastal regions of the United States. This research used direct comparative studies to assess foraging activities and beekeeping-management responses which are expected to govern the performance of Africanized bees as crop pollinators. European colonies fielded on average $3\times$ as many foragers as did Africanized colonies and had percentages of colony members foraging that were nearly $3\times$ as high. European colonies also had much greater variability in foraging activity (ranges: 42-1679 foragers for European bees; 119-352 foragers for Africanized bees); European …

Rebirth Through Narrative: John Bunyan's Autobiographies ("Grace Abounding To The Chief Of Sinners")., Constance A. Douglas

LSU Historical Dissertations and Theses

John Bunyan, while in Bedford gaol, composed two autobiographical narratives, one published in 1666, titled Grace Abounding to the Chief of Sinners, and a second, published posthumously in 1765, titled A Relation of the Imprisonment of Mr. John Bunyan. Since its recovery, the Relation has been published as the concluding section of Grace Abounding, seemingly suggesting that the doubting sinner of Grace Abounding demonstrates his assurance of salvation by becoming the confident spokesman for dissent in the Relation. In this study, however, I argue that the Relation is Bunyan's first self-construction from prison and Grace Abounding the second; thus the …

The Louisiana Cooperative Extension Service: A Descriptive History Of Its Origin And Development. (Volumes I And Ii)., Edwin Clark Forrest Jr

LSU Historical Dissertations and Theses

This dissertation studies the conditions which brought the Louisiana Cooperative Extension Service (LCES) into existence in 1914 and which have sustained it for over 70 years. The U.S. Department of Agriculture estimates that 40 percent of Russia's population consists of farmers and that approximately 70 percent of China's population are farmers. The significance of these figures in relation to productivity is apparent when contrasted with the United States farm population of 2 percent. The current high level of production in American agriculture, sustained by such a small percentage of the population, is not an accident, as Professor Roy V. Scott, …

Rice Stink Bug, Oebalus Pugnax (F.), On Rice: Evaluation For Plant Resistance, Interaction Of Field Fungi With Feeding Damage, And Evaluation Of Insecticides For Control., Marieanne Eva Hollay

LSU Historical Dissertations and Theses

Feeding punctures of the rice stink bug (RSB), Oebalus pugnax (F.), provide fungi entry sites into rice, Oryza sativa (L.), grains and kernels (hulled grains). Feeding sheaths also serve as a source of nutrients for fungi. Grain spotting fungi did not affect the percentage of spotted kernels (pecky rice) and significantly reduced full grain weight only at low infestation rates of one and two RSB per panicle. Panicles had been treated with a single application of propriconazol (1000 ppm) soon after flowering and later infested in the early milk stage with RSB adult pairs for 9 days. Propriconazol was not …

'Tifton 292' was the most preferred grass by neonate larvae, while 'OSU 74 X 11-2' was the least preferred grass. 'Tifton 78' was the most susceptible host, while 'OSU 71 X 6-7' was the least suitable host to FAW …

Management Of Rhizoctonia Aerial Blight Of Soybean And Biology Of Sclerotia Of Rhizoctonia Solani Kuhn (Louisiana)., Gary Fischer Joye

LSU Historical Dissertations and Theses

Rhizoctonia Aerial Blight (RAB) has caused severe damage on susceptible soybean cultivars throughout the southern soybean growing areas in Louisiana and the southeastern United States. During the 1983, 1984, and 1985 growing seasons, several greenhouse and field experiments were conducted to determine the influence of cultural practices (row spacings, plant populations, potassium fertilizer rates, and fungicide treatments) on RAB. A row spacing of 25 cm resulted in higher yields than row spacings of 50, 75, or 100 cm, regardless of disease rating. After the crop canopy had reached its maximum density, disease ratings were not significantly different between row spacings …

Spacing Of Repetitions And Contextual Interference Effects In Motor Skill Learning., Harry John Meeuwsen

LSU Historical Dissertations and Theses

Three experiments are reported that examined the possibility that the contextual interference effect in motor skill learning is a variation of a multiple trial spacing of repetitions effect. Specifically, the question why a non-spaced condition in a spacing of multiple trials motor learning paradigm has not produced predicted retention deficits. Subjects in all experiments learned to perform a simple motor skill in a criterion movement time. Experiments 1 and 2 examined why spacing of multiple trials did not produce expected retention performance benefits in previous spacing experiments. The results of Experiment 1 and 2 showed that the randomness of the …

An Investigation Of The Inference And Mapping Components Of The Componential Theory Of Analogical Reasoning., Catherine Sheard

LSU Historical Dissertations and Theses

Sternberg's componential theory of analogical reasoning (1977) provides a series of steps that may be followed in order to solve analogies. According to Sternberg, when given a simple analogy (in the form A:B::C: (D$\sb1$, D$\sb2$, D$\sb3$)) the reasoner: (a) encodes the terms of the analogy, (b) infers the relation between A and B, (c) maps the relation between A and C, (d) applies a relation analogous to the inferred one from C to each answer option, choosing the closer option, and (e) responds. The purpose of this research was to further investigate the inference and mapping processes of the componential …

Classical And Statistical Thermodynamics Of Gas Solubility In Polar Fluids., Christopher Paul Williams

LSU Historical Dissertations and Theses

The solubilities of argon and of three binary gas mixtures of nitrogen and methane, 25%CH$\sb 4$ - 75%N$\sb 2$, 50%CH$\sb 4$ - 50%N$\sb 2$ and 75%CH$\sb 4$ - 25%N$\sb 2$, in water have been measured at a temperature of 323K for pressures up to 124.1 MPa. The data have been correlated using the established forms of the Krichevsky-Kasarnovsky and Krichevsky-Ilinskaya equations and are in agreement with previous studies. The performance of the Krichevsky-Ilinskaya equation has been improved by using Wilson's equation in place of the two-suffix Margules equation to predict the non-ideality associated with the solute gas in the solution. …

Feeding And Microspatial Relationships Of Meiobenthic Harpacticoid Copepods With Microbial Flora., Alan William Decho

LSU Historical Dissertations and Theses

Feeding processes and their relationship to microspatial patterns were examined for several harpacticoid species. Field evidences and laboratory radiolabel experiments suggest that diatoms comprise a major portion of the food resources ingested by harpacticoids. Bacteria and mucus-exopolymer secretions (associated with the bacteria and diatoms) are also ingested, coincidently while ingesting diatoms. Also, significant ontogenetic shifts in food resource utilization occur from naupliar to adult stages. Field grazing rate studies were conducted on an intertidal mudflat over different portions of a tidal cycle using several harpacticoid species (Scottolana canadensis, Microarthridion littorale, Paronychocamptus huntsmani). Highest grazing rates for S. canadensis occurred just …
