Investigation Of Flow Patterns In Various Wastewater Treatment Facilities, Thomas Joseph Martin Jr
Investigation Of Flow Patterns In Various Wastewater Treatment Facilities, Thomas Joseph Martin Jr
LSU Historical Dissertations and Theses
The theoretical hydraulic retention time of wastewater treatment plants is often used to predict the efficiency of treatment and to calculate operational parameters. However, these values are related to the actual hydraulic retention time. When there is a large discrepancy between the actual and predicted values, the actual hydraulic retention time can be determined by marking a parcel of wastewater and recording its passage through the system. This investigation utilized rhodamine WT, a fluorescent dye, to track the movement of wastewater through a stabilization lagoon and a rock-reed filter. The loss of rhodamine WT to sorption, biodegradation and photodegradation was …

Musical Theory And Practice In The Stage, Film, And Non-Theatre Collaborative Works Of Bertolt Brecht And Hanns Eisler, 1930-1956, Philip Lee Craik
Musical Theory And Practice In The Stage, Film, And Non-Theatre Collaborative Works Of Bertolt Brecht And Hanns Eisler, 1930-1956, Philip Lee Craik
LSU Historical Dissertations and Theses
The collaborative works of Bertolt Brecht and Hanns Eisler are based on a conscious aesthetic rising out of the application of the principles of dialectical materialism to all aspects of dramatic writing, musical composition, and theatre production. Although Brecht had definite opinions about the use of music in his own epic theatre productions, it was not until he met Eisler that he discovered a philosophical basis for those opinions in the writings of Hegel and Marx. The early collaborative work of these two was shaped by their association with the German Workers' Music Movement which took an active part in …

The Relation Of Compliance To Quality Of Life In Dialysis Patients., Linda S. Dietz
LSU Historical Dissertations and Theses
The goal of the current study was to gain knowledge of the impact that dietary compliance has on quality of life for end-stage renal disease patients receiving chronic in-center hemodialysis. As a result of this type of research, health care professionals may better understand the individual and collective influence that various aspects of dietary compliance have on quality of life. This knowledge may be helpful in making future recommendations about the necessity of the dietary regimen. This study investigated the relation between three commonly employed physiological parameters of dietary compliance (blood urea nitrogen, potassium, and intersession weight gain) and four …
An Empirical Analysis Of The Effects Of Quality Factors On The Price Of Rough Rice In Louisiana., John Frederick Denison
An Empirical Analysis Of The Effects Of Quality Factors On The Price Of Rough Rice In Louisiana., John Frederick Denison
LSU Historical Dissertations and Theses
This dissertation analyzes the effects of quality factors on prices paid producers for long and medium grain rough rice in Louisiana. Rough rice prices, and other information surrounding quality, were collected for the study for the 1986/87 and 1987/88 marketing years from the Louisiana Farm Bureau Marketing Association in Crowley, Louisiana. The relationship between the price of rough rice, and its quality attributes or characteristics, was analyzed in a hedonic price framework. A conceptual model for the Louisiana rough rice market was constructed, and estimated premiums and discounts reported for a set of quality factors believed to influence producer prices. …

Effects Of Cocaine Use And Withdrawal On Clinical Memory And New Learning., Madeline Uddo-Crane
LSU Historical Dissertations and Theses
This project was conceptualized as an exploratory examination of the neuropsychological sequelae of cocaine abuse, specifically the drug's effect on new learning and memory. The experimental groups were composed of 30 veterans enrolled in a drug treatment program for cocaine abuse. This group was divided equally by route of administration, i.e., group one included 15 individuals whose preferred route of administration was intravenous injection; group two included 15 individuals whose preferred route of administration was smoking. The comparison group consisted of 15 individuals enlisted in the National Guard. The groups were essentially homogeneous, with a mean age of 34.6 ($SD$ …
Dispersion And Physiological Ecology Of Mosquito Adults In Louisiana Ricelands., Alan Richard Holck
Dispersion And Physiological Ecology Of Mosquito Adults In Louisiana Ricelands., Alan Richard Holck
LSU Historical Dissertations and Theses
A sampling technique for estimating the size of adult mosquito populations in vegetation was developed. Regression analysis was used to obtain absolute density estimates from sweep net. Diurnal population size estimates of Louisiana riceland mosquitoes were made on a 35.6-square km site 5 km south of Kaplan, LA. Four mosquito species were present: Psorophora columbiae, Anopheles quadrimaculatus, An. crucians and Culex salinarius. Mosquito species were highly stratified in their distribution. Psorophora columbiae was primarily observed in pastures with livestock and in rice fields. Both Anophelines were found only in structures. Culex salinarius did not exhibit habitat preference. Anopheles quadrimaculatus exhibited …
Nonresonant Multiphoton Ionization Of Alkaline Earth Atoms In Intense Laser Fields., Dal-Woo Kim
Nonresonant Multiphoton Ionization Of Alkaline Earth Atoms In Intense Laser Fields., Dal-Woo Kim
LSU Historical Dissertations and Theses
When an atomic beam interacts with a high intensity laser beam, ionization occurs even if the photon energy is less than the threshold level for ionization of the atom. In this thesis, nonresonant multiphoton ionization of alkaline-earth atoms is examined experimentally. Since alkaline-earth atoms have doubly excited states just above and sometimes below the first ionization threshold level and are easily ionized with relatively low intensity, they are ideally suited for studying the role of electron correlations in multiphoton ionization. This motivated a careful and detailed investigation of the correlation of electrons and the multiphoton ionization mechanism. A spectroscopic study …
Agrobacterium Tumefaciens - Mediated Transfer Of Plant Dna For Gene Expression Analysis., Woo Sung Lee
Agrobacterium Tumefaciens - Mediated Transfer Of Plant Dna For Gene Expression Analysis., Woo Sung Lee
LSU Historical Dissertations and Theses
Agrobacterium tumefaciens causes crown gall tumor primarily in dicotyledonous plants. The infection mechanism reveals that a portion of bacterial DNA (T-DNA) is transferred into the plant nuclear genome. This transformation system is widely utilized in plant genetic engineering and plant molecular biology. In this dissertation, two experiments were carried out. First, the copy number, physical structure and F1 segregations of T-DNA copies were analyzed, attempting to understand the mode of T-DNA integration into the plant genome. While the mechanism of Agrobacterium response to plant signals and generation and transfer of T-DNA intermediates through actions of virulence genes is generally understood, …
The Impact Of Options Listing On The Information Content Of Annual Earnings Announcement., Tinwah Richard Lau
The Impact Of Options Listing On The Information Content Of Annual Earnings Announcement., Tinwah Richard Lau
LSU Historical Dissertations and Theses
The purpose of this study is to determine whether options listing induces additional information acquisition and processing and hence causes a commensurate reduction in the information content of annual earnings announcements. The U-statistic is used to measure the information content of annual earnings announcements. The dissertation tests the options listing effects on four different designs: (i) all exchange (NYSE/AMEX) firms, (ii) large exchange firms versus small exchange firms, (iii) positive unexpected earnings firms versus negative unexpected earnings firms, and (iv) all over-the-counter firms. The research found that, after options listing, the U-statistic of the exchange firms decreases significantly during the …
Re-Inventing The Public Sphere: Critical Theory, Social Responsibility, Schools, And The Press., John Pace Konopak
Re-Inventing The Public Sphere: Critical Theory, Social Responsibility, Schools, And The Press., John Pace Konopak
LSU Historical Dissertations and Theses
This study examines the contemporary discourses of journalism and pedagogy from the standpoint of critical theory to assess the impact of technocratic rationality and instrumental logic on the practices of communication and education. It is premised on the observation that, spurred by the imperatives of trans-national capital accumulation, privatization inimical to democratic interests has begun to colonize public education. The study represents an effort to reactivate a concept and rhetoric of "social responsibility" that would animate a project of reclaiming cultural space to be occupied by a "public sphere," in a struggle analagous to that waged against feudalism and monarchical …
Modeling Flat Flames Burning Chlorinated Methanes In A Methane/Air Environment., Gary Peyton Miller
Modeling Flat Flames Burning Chlorinated Methanes In A Methane/Air Environment., Gary Peyton Miller
LSU Historical Dissertations and Theses
A numerical model was developed to simulate flat flames burning chlorinated methanes in a methane/air environment. The model uses a reaction mechanism containing 341 reactions and 58 species. A time-stepping solution with linearized source terms and a strict convergence criteria had to be developed to allow for convergence of the conservation equations. Simulations of ten flames were made, five simulations of dichloromethane/methane/air flames, and five simulations of carbon tetrachloride/methane/air flames. For each fuel type, simulations were performed at a constant molar Cl/H ratio of 0.3 for a stoichiometric flame, a fuel-rich flame, and a fuel-lean flame. The other simulations were …
Gongora's "Soledades" As A Problem Of Language And Meaning In Seventeenth Century Spain., Ted Eustace Mcvay Jr
Gongora's "Soledades" As A Problem Of Language And Meaning In Seventeenth Century Spain., Ted Eustace Mcvay Jr
LSU Historical Dissertations and Theses
The exploration of the epistemological assumptions necessary for the interpretation of Luis de Gongora's "Soledades" is an area of critical attention that has gone virtually neglected since his 1927 "rehabilitation." This study offers an approach to understanding the long, difficult poem and the bitter critical reaction against it in the context of the seventeenth-century shift of predominant epistemologies discussed by Michel Foucault in The Order of Things. An approach that focuses on how the world is known is most appropriate to a study of the "Soledades" for several reasons, one being that those writers who attacked the poem did so …
An Examination Of The Effect Of Financial Risk On The Manager's Choice Of Accounting Methods., Linda Marie Nichols
An Examination Of The Effect Of Financial Risk On The Manager's Choice Of Accounting Methods., Linda Marie Nichols
LSU Historical Dissertations and Theses
This study examines the effect of the firm's level of financial risk on management's preference for full-cost or successful-efforts accounting in the oil and gas industry. Agency theory predicts that firms with increasing levels of financial risk have an incentive to switch to an accounting method which tends to increase net tangible assets and which creates more stable earnings in order to avoid technical default on loan covenants. Therefore, it is expected that successful-efforts firms with increasing levels of financial risk will tend to switch to use the full-cost accounting method. Past studies have used leverage as a surrogate for …
Theories Of Economic Regulation And The Development Of The Doctrine Of "Conspiracies In Restraint Of Trade" In The Labor Market., Edd Sidney Noell
Theories Of Economic Regulation And The Development Of The Doctrine Of "Conspiracies In Restraint Of Trade" In The Labor Market., Edd Sidney Noell
LSU Historical Dissertations and Theses
The purpose of this dissertation is to analyze the development of the doctrine of "conspiracies in restraint of trade" in the labor market by means of an application of two models of economic regulation. As heuristic devices, these models are utilized to explain the formation of English and American labor law in three different eras. The market failure model posits that labor market regulators seek to remedy unequal bargaining power and asymmetric information so as to achieve economic efficiency. This model's 'liberty and virtue' component emphasizes the normative end of character formation. According to the interest group model, organized labor …
A Catalyst For Change: The Libretti Of Jean -Philippe Rameau's 'Tragedies En Musique', (1733-1764)., Jonathan Philip Joseph Radvan
A Catalyst For Change: The Libretti Of Jean -Philippe Rameau's 'Tragedies En Musique', (1733-1764)., Jonathan Philip Joseph Radvan
LSU Historical Dissertations and Theses
Jean-Philippe Rameau was the most celebrated composer of opera and the foremost music theorist in eighteenth century France and great attention has justly been given to his musical and theoretical works, but there has been no corresponding study, such as this one, of the libretti of his operas, which depart from the precepts of neo-classical drama and reflect a new sentimental age. The librettists of the tragic operas of Rameau introduced many innovations to the tragic genre, hitherto forbidden by the rigid canons of neo-classicism. They were free to do so because opera was a relatively new genre which could …
Cognitive And Affective Outcomes Of Varying Levels Of Structured Collaboration In A Computer-Based Learning Environment., Judith Lavine Repman
Cognitive And Affective Outcomes Of Varying Levels Of Structured Collaboration In A Computer-Based Learning Environment., Judith Lavine Repman
LSU Historical Dissertations and Theses
This study investigated cognitive and affective outcomes resulting from the use of varying levels of structured peer collaboration (unstructured, structured, and structured with training) in a computer-based learning environment. The study was designed to apply research findings showing a positive relationship between giving explanations and achievement into classroom practice. The sample consisted of 190 students enrolled in nine sections of seventh grade social studies at two middle schools in East Baton Rouge Parish, LA. The schools were selected because they contained large percentages of students at-risk of school failure. Intact classes were randomly assigned to receive one of the three …

The Macroeconomic Effects Of Fiscal And Monetary Impulses And Of Financial Crisis In The United States During The Interwar Period., Prosper Raynold
LSU Historical Dissertations and Theses
This dissertation employs vector autoregressive techniques to improve our empirical understanding of fiscal and monetary policy and the effects of financial crisis in the interwar period. The issues investigated include: (a) the validity of the Ricardian equivalence and debt monetization hypotheses; (b) the effect of changes in the money supply on output, prices, and interest rates; (c) the impact of changes in average marginal tax rates and government expenditures on the macroeconomy; and (d) the effects of disruptions in financial intermediation and deterioration in the quality of private balance sheets on the macroeconomy. Two vector autoregressive models are estimated and …
Floral Ontogeny Of Mimosoid Legumes., Jose Israel Ramirez-Domenech
Floral Ontogeny Of Mimosoid Legumes., Jose Israel Ramirez-Domenech
LSU Historical Dissertations and Theses
Comparative floral ontogeny in mimosoid legumes was analyzed among representative genera in three major tribes Mimoseae, Acacieae and Ingeae. Details on floral and inflorescence ontogeny in one mimosoid species is described and illustrated for Mimosa strigillosa Torr. & Gray. Three features studied developmentally include: variation in number of parts, patterns of arrangement and inflorescence architecture. Suppression occurs along inflorescences that develop synchronously, when basal flowers are retarded. Tetramerous flowers are considered a reduction or suppression from basic pentamerous flower. Divergent patterns in order of sepal initiation and stamen initiation and proliferation are found during early ontogeny. Four patterns found in …
Rice Bran Stabilization By Improved Internal And External Heating Methods., Jiaxun Tao
Rice Bran Stabilization By Improved Internal And External Heating Methods., Jiaxun Tao
LSU Historical Dissertations and Theses
Rice bran stabilization was conducted by internal (microwave), external (oven drying and steam retorting) heating and non-heating ($\sp{60}$Co irradiation) treatments to improve currently used methods. Two commercial rice varieties cultivated in Louisiana, one long grain (Lemont) and a medium grain (Nato), were milled to collect bran samples. The bran was analyzed for its proximate composition and various physical and thermal characteristics. The proximate composition for long and medium grain bran, respectively, was: moisture, 11.2% and 10.8%; protein, 16.07% and 16.20%; fat, 19.20% and 21.97%; crude fiber, 8.49% and 8.41%; ash, 9.23% and 9.46%; and nitrogen-free extract, 47.01% and 44.07%. Physical …
Effect Of Knowledge On Teachers' Interactive Thinking And Children's Overhand Throwing Performance., Edward Walkwitz
Effect Of Knowledge On Teachers' Interactive Thinking And Children's Overhand Throwing Performance., Edward Walkwitz
LSU Historical Dissertations and Theses
This study examined the effects of knowledge of subject matter (overhand throwing) and of throwing-specific instructional strategies on teacher's interactive thinking. The impact of these two categories of teacher knowledge on lesson objectives, the quality of skill practice, and kindergartners' overhand throwing development over a unit of instruction were also explored. Eight kindergarten classroom teachers who possessed high generic teaching skill competence taught a six-week overhand throwing unit to the children (N = 150) in their intact classes. Prior to the unit, four of the teachers were exposed to a training program that increased their knowledge of overhand throwing. Four …
The Impact Of Vertebrate Herbivores On Primary Production Of Sagittaria Marshes In The Wax Lake Delta, Atchafalaya Bay, Louisiana., Jenneke Maria Visser
The Impact Of Vertebrate Herbivores On Primary Production Of Sagittaria Marshes In The Wax Lake Delta, Atchafalaya Bay, Louisiana., Jenneke Maria Visser
LSU Historical Dissertations and Theses
Aboveground production of tidal freshwater marshes dominated by Sagittaria latifolia or Sagittaria platyphylla is best estimated with nondestructive techniques. A nondestructive method for estimation of Sagittaria aboveground biomass and production was developed using multiple regression. This technique yielded estimates of aboveground biomass of Sagittaria ranging from 0 to 1875 g/m$\sp2$; harvested aboveground biomass of Sagittaria ranged from 85 to 1356 g/m$\sp2$. Aboveground production was estimated nondestructively on the basis of permanent plots (465-3809 g/m$\sp2$/yr) and destructively on the basis of end-of-season biomass (775-4056 g/m$\sp2$/yr). Destructively estimated belowground production ranged from 233 to 1199 g/m$\sp2$/yr. Aboveground production was positively correlated with …
Three Essays On The Determinants And Effects Of Public Sector Bargaining Laws., Melissa S. Waters
Three Essays On The Determinants And Effects Of Public Sector Bargaining Laws., Melissa S. Waters
LSU Historical Dissertations and Theses
The theoretical foundation of this model is the economic theory of regulation as developed by Stigler; in addition, modifications of the economic or special interest theory implied by the Public Choice school of thought are employed. A synthesis of these two theories of regulation, then, provides the framework upon which to develop a general model of the causes and consequences of laws regulating the bargaining rights of state employees. Topic One is devoted exclusively to the determinants of state-wide bargaining rights laws. The data are pooled over two years, and state laws are classified into one of three possible categories: …
Electrochemical And Spectroscopic Characterization Of Bis(Ethylenedithio)Tetrathiafulvalene, Tetramethyltetraselenafulvalene And Their Perchlorate Salts., Roberto Luzon Wong
Electrochemical And Spectroscopic Characterization Of Bis(Ethylenedithio)Tetrathiafulvalene, Tetramethyltetraselenafulvalene And Their Perchlorate Salts., Roberto Luzon Wong
LSU Historical Dissertations and Theses
Electroanalytical methods (cyclic voltammetry (CV), rotating disk electrode (RDE) and rotating ring disk electrode (RRDE) voltammetry) have been used to characterize the oxidation products of bis(ethylenedithio)-tetrathiafulvalene (BEDT-TTF or ET) and tetramethyltetraselenafulvalene (TMTSF) in two commonly used solvents, acetonitrile (CH$\sb3$CN) and 1,1,2-trichloroethane (1,1,2-TCE). Cyclic voltammetry has revealed that the electro-oxidations of ET and TMTSF each occur initially via two one-electron steps representing the formation of the monocation radical and dication species. The electrochemical behaviors of TMTSF and ET in both solvents are summarized. UV/VIS spectroscopy was used to characterize TMTSF, ET and their perchlorate salts in solution. Solution spectra of TMTSF, …

The development of an automated small sample (0.5 to 50mg) calorimeter is discussed and evaluated. With this calorimeter, measurements of the specific heat of Gd$\sb1$Ba$\sb{\rm 2-x}$Sr$\sb{\rm x}$Cu$\sb3$O$\sb7$ for x = 0, 0.25, and 0.5 in the temperature range 0.6 to 3 K are reported. Measurements on the x = 0 sample agree with data collected by other groups. In addition, measurements in magnetic fields from 0 to 3 T for the x = 0 sample are reported. In each case a peak in the specific heat at the antiferromagnetic ordering temperature (the Neel temperature) is recorded and analyzed. Strontium doping …
The Development Of A Fetal Uterine Cell In Vitro Coculture System For Mammalian Embryos., Klaus Enrique Wiemer
The Development Of A Fetal Uterine Cell In Vitro Coculture System For Mammalian Embryos., Klaus Enrique Wiemer
LSU Historical Dissertations and Theses
In Experiment I, 125 two-pronuclear murine ova were cultured in either Ham's F-10 plus l5% human serum (HF-10h), on a monolayer of human uterine fibroblasts (HUC) or fetal bovine uterine fibroblasts (FBUC). After 96 hours in culture, 2.4% embryos in HF-10h were viable compared with 45.2% and 61% for embryos on HUC and FBUC, respectively. Results suggest that monolayers were advantageous to medium alone for culturing murine embryos. Experiment II was conducted to assess the development of 117 bovine embryos in HF-10 (Treatment A), on a monolayer of FBUC (Treatment B) or hormone-pretreated FBUC (Treatment C). Embryo viability assessed at …
