Quasi Elastic Electron Scattering In Uranium-238 (Longitudinal, Sum-Rule, Pion, Nuclear, Structure)., Charles Carroll Blatchley Jan 1984

Quasi Elastic Electron Scattering In Uranium-238 (Longitudinal, Sum-Rule, Pion, Nuclear, Structure)., Charles Carroll Blatchley

LSU Historical Dissertations and Theses

Electron scattering data from the MIT-Bates linear accelerator were used to derive longitudinal and transverse response functions (S(,L), S(,T)) for the quasi-elastic (QE) kinematic region from uranium targets. Incident energies ranged from 100 to 690 MeV at five laboratory scattering angles: 60, 90, 134.5, 140, and 160 degrees. The Rosenbluth separations using all five angles were obtained at three momentum transfers (q) from 250 to 500 meV/c. Both response functions compared well to relativistic Fermi Gas Model (FGM) predictions at higher values of q, but the S(,L) peak was progressively lower and broader than the FGM at lower q. This …

A Comparison Of Two Developmental Models Of Concept Learning., Roberta Naomi Chinn Jan 1984

A Comparison Of Two Developmental Models Of Concept Learning., Roberta Naomi Chinn

LSU Historical Dissertations and Theses

Recent research has identified changes in the strategies used and the shape of learning curves of children learning concepts as a function of developmental level. Two recent models have been proposed to explain these changes. One model views these changes as an improvement of hypothesis-testing strategies. The other model views these changes as a switchover from reliance on one type of learning process to a second type of learning process. The present study compared the two models with respect to the strategies used and the shape of the learning curves of four grade levels of subjects. One hundred twenty-nine children …

"They Fought Splendidly!": The Struggle For Port Hudson (Civil War, Louisiana, Military)., Lawrence Lee Hewitt Jan 1984

"They Fought Splendidly!": The Struggle For Port Hudson (Civil War, Louisiana, Military)., Lawrence Lee Hewitt

LSU Historical Dissertations and Theses

This dissertation examines the Confederate occupation of Port Hudson, Louisiana, and the Union efforts to capture the bastion during the period August 1862-July 1863. Though it recounts the garrison life of the soldiers, it emphasizes governments. Throughout the period under consideration, the Confederate government's objective in garrisoning Port Hudson and Vicksburg was to maintain the vital Red River supply-line. That waterway facilitated the east-west flow of manpower, munitions and foodstuffs between the heart of the Confederacy and the Trans-Mississippi. The United States government recognized the importance of this supply-line and made control of the Mississippi River one of its primary …

A Study Of The Inheritance Of Resistance To Leaf Smut Of Rice In An Undefined Diallel Cross., Haroun Kabadi Jan 1984

A Study Of The Inheritance Of Resistance To Leaf Smut Of Rice In An Undefined Diallel Cross., Haroun Kabadi

LSU Historical Dissertations and Theses

The inheritance of resistance to leaf disease of rice (Oryza sativa L.), caused by the fungus Entyloma oryzae H. & P. Sydow & Sydow, was studied in an undefined diallel set of crosses involving five rice lines previously rated for leaf smut resistance. The five lines consisted of two very resistant lines, two very susceptible lines, and one intermediate line. The diallel set of crosses consisted of the five parental lines considered to be non-random, 20 F(,1) hybrids obtained from the single crosses of the five lines in all combinations, and 20 F(,2) families derived from self-pollination of the F(,1) …

Evaluation Of Reduced Washing And Hot Packing As Shelf-Life Extenders Of Creamed Cottage Cheese., Edward E. Oamen Jan 1984

Evaluation Of Reduced Washing And Hot Packing As Shelf-Life Extenders Of Creamed Cottage Cheese., Edward E. Oamen

LSU Historical Dissertations and Theses

Cottage cheese coagulum, formed by direct acidification of 189 liters of 12.00% reconstituted nonfat dry milk (NFDM), was cut, cooked and drained. Without washing, curd was creamed with hot dressing, held for various times to allow cream absorption, packaged, cooled and stored at 5(DEGREES)C. Dressing temperatures of 60, 71 or 82(DEGREES)C and holding times of 0, 30 or 60 min were investigated in order to determine the best combination for unwashed curd. Such parameters as yield, curd-to-cream ratio, amount of free cream, total solids, fat, microbiology, organoleptic properties and shelf-life were used to evaluate creamed unwashed cottage cheese quality. No-washing …

Typicality And Familiarity Effects In Children's Memory: The Interaction Of Processing And The Knowledge Base., Gary Todd Rosenthal

LSU Historical Dissertations and Theses

Third- and sixth-graders and adults participated in an experiment based upon Hunt and Einstein's (1981) theory which relates study activities or processing task to subsequent memory performance. Participants performed a processing task designed to emphasize either relational or item-specific information. In addition, the information about the words available in each subject's knowledge base was measured in two ways: relational information was assessed with a typicality rating task and item-specific information was assessed with an attribute listing task. The experiment consisted of three phases. In the first phase subjects performed one of two processing tasks on a list containing typical, atypical …

Women And Class: A Theoretical And Empirical Analysis (Stratification)., Pamela Jean Jenkins Jan 1984

Women And Class: A Theoretical And Empirical Analysis (Stratification)., Pamela Jean Jenkins

LSU Historical Dissertations and Theses

This study was an attempt to conceptually and empirically expand Marx's class analytic scheme to include the unique position of women. The goals in this study were to: (1) discuss and resolve certain issues surrounding the definition of the working class; and (2) to test an empirical measure of class that would reflect women's roles in the home and the workplace. The first goal was met basically by a theoretical model that allowed the conceptualization of women and their place in production (both in home and work) into an already existing class structure. This study concentrated on the differences in …

The Design And Evaluation Of An Integrating Monitoring Device For Ozone Using 10,10'-Dimethyl-9,9'-Biacridylidene., Marion Rene Surgi Jan 1984

The Design And Evaluation Of An Integrating Monitoring Device For Ozone Using 10,10'-Dimethyl-9,9'-Biacridylidene., Marion Rene Surgi

LSU Historical Dissertations and Theses

A unique film badge design in which a reagent 10,10'-dimethyl-9,9'-biacridylidene (DBA) is dissolved homogeneously in a gas-permeable, silicone-polycarbonate copolymer film, was evaluated. The ambient concentration of ozone can be determined from its reaction with DBA. The disappearance of DBA upon ozonolysis can be monitored at 4300 (ANGSTROM) without extraction or desorption from the polymer membrane. Unlike other reagents for ozone determination, DBA is specific for ozone. Interferences from nitrogen dioxide and sulfur dioxide are less than 1%. Prior to this experimental work, a mathematical diffusion model was developed to predict the response of such a device to a given pollutant …

Studies In The Relationship Between Distinctive Features And Acoustic Cues (Phonetics, Phonology)., Thomas F. Walsh Jan 1984

Studies In The Relationship Between Distinctive Features And Acoustic Cues (Phonetics, Phonology)., Thomas F. Walsh

LSU Historical Dissertations and Theses

The relationship between the Distinctive Feature (DF) (+OR-)Voice and its acoustic manifestation has generated a great deal of discussion in recent years. Although it is well known that the phonological voicing contrast is often not manifested in terms of actual glottal pulsation, the exact acoustic manifestation has been debated. The collection of papers presented herein considers perceptual evidence for the acoustic manifestation of (+OR-)Voice in English stops in utterance-final position, produced without release and with no glottal pulsation during closure. It is concluded that in such cases, the primary acoustic cue to (+OR-)Voice is the preceding vocalic transition. That is …

High Temperature Combustion Of Selected Chlorinated Hydrocarbons., David Leslie Miller Jan 1984

High Temperature Combustion Of Selected Chlorinated Hydrocarbons., David Leslie Miller

LSU Historical Dissertations and Theses

A study combining ignition delay measurements and quenched product distributions from shock-tube experiments with chlorinated hydrocarbons has been conducted to develop a better understanding of the combustion characteristics of these compounds which are candidates for incineration. The ignition delay times of selected C(,1), C(,2) and C(,6) chlorinated hydrocarbon- stoichiometric oxygen mixtures have been measured behind reflected shock waves at a pressure of 1.8 atm over the temperature range 1200-1700K. Studies were also conducted with mixtures of chlorinated and nonchlorinated hydrocarbons to examine the effect of chlorine atom/hydrogen atom ratio on ignition delay behavior. The results indicate that contrary to conventional …

Fundamental Photoemission Studies On Semiconductor Electrolyte Junctions (Solvated Electrons)., Ricardo Enrique Borjas Jan 1984

Fundamental Photoemission Studies On Semiconductor Electrolyte Junctions (Solvated Electrons)., Ricardo Enrique Borjas

LSU Historical Dissertations and Theses

Photoelectron emission currents from P-GaAs and p-InP into aqueous and non-aqueous electrolytes have been measured and current theories examined critically. The linearized optimal current/potential relation for p-GaAs followed the 3/2 power law and gave the reciprocal power results 0.66 (+OR-) 0.17 and 0.61 (+OR-) 0.09 at pH 7.0 and 11.4, respectively. The threshold potential was -1.00 V (+OR-) 0.09 V(SCE) at both pH's. Corresponding experiments at p-InP gave 0.70 (+OR-) 0.07 for reciprocal power at these pH's and a threshold potential of -0.65 V (+OR-) 0.02 (SCE). Both crystals followed the 3/2 power law for the photocurrent/wavelength relation with work …

The Habitat And Cost Of Production Of Domestic Petroleum Resources., John Daniel Grace Jan 1984

The Habitat And Cost Of Production Of Domestic Petroleum Resources., John Daniel Grace

LSU Historical Dissertations and Theses

The geologic characteristics of an oil field, most importantly its depth and surface area, have significant impacts on the average cost of extracting petroleum. These characteristics of petroleum habitat constitute a measure of "deposit quality," as ore grade does in the production of metals. This measure can be used to separately evaluate the effects on cost, over time, of changing depost quality and technological advance. A sample of 156 U.S. fields, with average estimated ultimate recovery of 50 million barrels, was analyzed to quantify the cross-sectional differences in average production cost on the basis of depth, area, productive capacity, reservoir …

Alpha-Methyl Functionalization Of Electron-Poor Heterocycles And Synthesis Of Novel Dipyridine And Phenanthroline Metallocyclic Palladium Complexes., Garry Edward Kiefer Jan 1984

Alpha-Methyl Functionalization Of Electron-Poor Heterocycles And Synthesis Of Novel Dipyridine And Phenanthroline Metallocyclic Palladium Complexes., Garry Edward Kiefer

LSU Historical Dissertations and Theses

The (alpha)-methyl functionalization of 2,9-dimethyl-1,10-phenanthroline was conducted via a four step procedure to give 2,9-bis(chloromethyl)-1,10-phenanthroline in high yield. Attempts to prepare this compound via a one-step free radical halogenation using NCS were unsuccessful, however, a comparative evaluation of this approach in other heterocycles demonstrated the potential for direct mono-chlorination. Additional functionalization procedures were investigated via the olefination of 2,2'-dipyridine and 1,10-phenanthroline. Following the oxidation of 6,6'-dimethyl-2,2'-dipyridine to the dialdehyele, standard Wittig reaction conditions were employed to obtain 6,6'-divinyl-2,2'-dipyridine, however, yields were low because of aldehyde insolubility. This method was replaced by the Wittig-Horner reaction utilizing heterocyclic phosphonates as precursors to …

The Velocity And Shape Of Gas Slugs Rising In Vertical Tubes And Rectangular Slots., Henry Valma Nickens Jan 1984

The Velocity And Shape Of Gas Slugs Rising In Vertical Tubes And Rectangular Slots., Henry Valma Nickens

LSU Historical Dissertations and Theses

The rise of a large gas bubble, or slug, through a closed, vertical, liquid-filled channel of infinite length has been investigated by means of potential flow theory. Three channel geometries are considered: (1) the circular tube, (2) the two-dimensional rectangular channel and (3) the three-dimensional rectangular slot. The effect of inter- facial surface tension is explicitly accounted for by application of the Kelvin-LaPlace equation, thus making the bubble shape an integral part of the solution. For the circular tube of radius R and diameter D, the solution is expressed in terms of the Stokes Stream Function which consists of an …

Molecular Analysis Of Induced Mutations At The Adh Locus (Alcohol Dehydrogenase, Restriction, Cloning, Southern, Blotting)., Mark Richard Kelley

LSU Historical Dissertations and Theses

Presented here are three distinct, but interwoven areas of mutation research and molecular genetics using Drosophila melanogaster as the test organism. The first section describes the characterization of the DNA replication process and DNA repair in the oocyte. This involved sex-linked recessive lethal tests on ethyl methanesulfonate (EMS) treated females and unscheduled DNA synthesis (UDS) studies involving EMS, methyl methanesulfonate (MMS) and N-ethyl-N-nitrosourea (ENU). Oocytes were positive for UDS with EMS and MMS in a DNA repair competent strain and negative in excision repair deficient strains. ENU was negative in a DNA repair competent strain. Since UDS is not quantitative …

George Vandenhoff, Nineteenth Century Elocutionist In America (Public Reader, Actor, "Art Of Elocution"; England; New York)., Bill Jaye Schooley Jan 1984

George Vandenhoff, Nineteenth Century Elocutionist In America (Public Reader, Actor, "Art Of Elocution"; England; New York)., Bill Jaye Schooley

LSU Historical Dissertations and Theses

Three generations of Vandenhoffs were among featured players in theatres of both America and England for over a century, 1808 through 1913. George Vandenhoff, the subject of this study, was the eldest son of the accomplished British tragedian, John Vandenhoff. Lauded in England, George accepted a theatrical booking in New York in 1842 and later became a resident of that city. Dissatisfied with changing trends in the theatre and perceiving a growing interest in public readings of literature, Vandenhoff ultimately turned his attention from the actor's stage to the reader's platform. One of the first to introduce Shakespearean readings, he …

Stewardship Of Creation: Some Implications For Economic Theory And Policy., John Harlan Mcdonald Jan 1984

Stewardship Of Creation: Some Implications For Economic Theory And Policy., John Harlan Mcdonald

LSU Historical Dissertations and Theses

Neoclassical economic theory defines an optimal or efficient allocation of natural resources as one which secures the maximum output of preferred goods and services, or as an allocation in which the resources are used in their highest valued uses. The theory is based on two important normative assumptions: the welfare of the community is an increasing function of the individual's welfare, and an individual is better off in a freely chosen position. These assumptions form a subjective theory of value which locates the source of intrinsic value in the individual's tastes and preferences; value or wealth is whatever satisfies the …

Stereoelectronic Effects In General Base Catalysis By Carboxylate. Theoretical Calculations And Studies In The Synthesis Of New Intramolecular Models Of Enzymatic Catalysis., Julian Tirado-Rives

LSU Historical Dissertations and Theses

The hypothesis of the existence of stereoelectronic effects in the reactions in which carboxylate acts as a general base catalyst is further studied through the use of theoretical methods. Ab initio calculations on the structures and relative energies of the syn and anti conformations of formic acid at different degrees of solvation are described. These calculations indicate that the syn conformation is more stable in aqueous phase than the anti by 11.9 (at the STO-3G//STO-3G level), 6.9 (4-31G//4-31G), and 2.5 kcal/mol (6-31G(,**)//4-31G). This last number, though, comes from single point calculations at the 6-31G(,**) level on the 4-31G optimized structure …

The Ethno-Archaeology Of The Houma Indians, Bryan L. Guevin Dec 1983

The Ethno-Archaeology Of The Houma Indians, Bryan L. Guevin

LSU Historical Dissertations and Theses

The focus of this research is comprised of two objectives. The first attempts to ethno-historically reconstruct the early historic culture of the Houma Indians of Louisiana based upon seventeenth and eighteenth century archival and documentary sources with attention being paid to such ethnographic aspects as Houma subsistence, social organization, and ceremonialism. The second objective, by way of utilizing additional historical documentation such as early cartographic evidence, predicts and locates historic Houma village sites. An archaeological examination and discussion of these sites is presented in terms of an attempt to diagnostically identify broad ethnic markers within the historic Houma material culture.

Coastal Louisiana Recent Land Loss And Canal Impacts, William W. Scaife, R. Eugune Turner, Robert Constanza Sep 1983

Coastal Louisiana Recent Land Loss And Canal Impacts, William W. Scaife, R. Eugune Turner, Robert Constanza

Faculty Publications

Annual coastal land loss in the sedimentary deltaic plain of southern Louisiana is 102 km2, which is correlated with man-made canal surface area. The relationships between land loss and canals are both direct and indirect and are modified by the deltaic substrate, distance to the coast, and availability of new sediments. Loss rates are highest in the youngest of the former deltas nearest the coast; they are lowest in the more consolidated sediments far from the coast. The average estimate for land loss at zero canal density in the six regression equations developed was 0.09%±0.13% annually, the present land loss …

Systematics Of The Water Snakes Of The Nerodia Cyclopion Complex, William Edward Sanderson Aug 1983

Systematics Of The Water Snakes Of The Nerodia Cyclopion Complex, William Edward Sanderson

LSU Historical Dissertations and Theses

The taxonomic status of the green water snake, Nerodia cyclopion, is re-evaluated. The two recognized subspecies are compared by using a variety of standard morphological characters, and significant differences are noted. Discriminant analysis of head-scale measurements provides highly significant separation of the two taxa. Examination of specimens from the zone of parapatry reveals no evidence of recent gene flow between the taxa. Based on these morphological data, plus the biochemical and ecological data of other workers, I suggest that the subspecies be recognized as full species, Nerodia eyelopion and Nerodia floridana.

A Study Of Polynuclear Aromatic Hydrocarbons On An Amino Bonded Phase Liquid Chromatographic Column In The Normal And Reversed Phase, Dori Karlesky, Dennis C. Shelly, Isiah M. Warner Mar 1983

A Study Of Polynuclear Aromatic Hydrocarbons On An Amino Bonded Phase Liquid Chromatographic Column In The Normal And Reversed Phase, Dori Karlesky, Dennis C. Shelly, Isiah M. Warner

Faculty Publications

Experiments were run using an n-propyl amine polar bonded phase (Chromosorb LC-9) liquid chromatographic column in both the normal and reversed phase mode. Results confirm that the mechanism of separation in the normal phase is due mainly to a charge transfer interaction between the lone pair electrons on the stationary phase nitrogen and the π electron cloud of the solute PNAs. Elution order seems to depend upon a combination of π energy, and type of ring condensation of the solute. Plots of log I versus number of aromatic carbons for catacondensed PNAs suggest that while the specific interaction is different …

The Distribution Of Macrobenthos In Barataria Basin, Louisiana, Antonio Liborio Philomena Feb 1983

The Distribution Of Macrobenthos In Barataria Basin, Louisiana, Antonio Liborio Philomena

LSU Historical Dissertations and Theses

Macrobenthos and environmental variables were measured in the Barataria basin, Louisiana, at 32 stations in November 1978. Three of the stations (Lake Salvador, Little Lake and St. Denis Bayou) were sampled bimonthly from November 1977 through November 1978. Abundance, diversity, and biomass results indicated two different areas: fresh, low-salinity habitats in the upper and middle basin with high biomass, abundance, and diversity, and high-salinity habitats in the lower basin with low biomass, abundance, and diversity. Over the whole basin, crustaceans were the most abundant organisms, while the mollusks dominated the biomass. Insects, nematodes, and oligochaetes were characteristic of freshwater habitats, …
