Inhomogeneous Relativistic Electron Systems: A Density Functional Formalism., Munagala Venkata Ramana Jan 1981

Inhomogeneous Relativistic Electron Systems: A Density Functional Formalism., Munagala Venkata Ramana

LSU Historical Dissertations and Theses

The correlation energy of an unpolarized relativistic electron gas is numerically calculated by summing ring diagrams due to both the longitudinal and transverse photon contributions. From this a local relativistic correlation potential is deduced which appears in the density functional theory of inhomogeneous systems where relativistic effects make important contributions. The non-relativistic gas results are found to be significant underestimates. A fitted form of the correlation energy and potential were used in a self-consistent calculation of energies of atoms of large Z. Trends of the correlation contribution across the periodic table are evaluated and discussed. Correlation contributions to the K(alpha)(,1) …

Electron-Phonon Scattering Rates In Antimony: Radio-Frequency Size Effect., Thomas Clifton O'Hara Jan 1981

Electron-Phonon Scattering Rates In Antimony: Radio-Frequency Size Effect., Thomas Clifton O'Hara

LSU Historical Dissertations and Theses

Temperature dependent radio-frequency size effect measurements have been performed on high-purity, single crystal antimony plates at thicknesses of 0.592 mm, 0.347 mm, and 0.238 mm. The natural logs of the amplitudes of the data are found experimentally proportional to T('2) in agreement with previous measurements. However, the data are analyzed according to a model in which the electron-phonon scattering frequencies are proportional to T('3), with the explanation that the T('2) behavior is due to the small pieces of Fermi surface in antimony. The electron-phonon scattering frequencies are determined for both holes and electrons and are found to be highly anisotropic …

The Austrian Problem Of Language And Peter Handke: A Documentation., Donald Russell Bailey Jan 1981

The Austrian Problem Of Language And Peter Handke: A Documentation., Donald Russell Bailey

LSU Historical Dissertations and Theses

Linguistic skepticism and the resultant awareness of the limits of language can be traced back to Hamann, Herder, and Humboldt, through Romanticism and French Symbolism, up to modern times. What has come to be called the crisis of language (Sprachkrise) can be viewed as one segment of a broader, multi-media phenomenon. The intensity of this crisis is concentrated in Austro-Hungary in the waning days of the Habsburg Monarchy. From this time forward supersensitivity to language remains a strongly Austrian phenomenon and can be followed through the European, German-language, and Austrian movements of this century, up to the founding of the …

Control Algorithms, Tuning, And Adaptive Gain Tuning In Process Control., Alberto Arner Rovira Jan 1981

Control Algorithms, Tuning, And Adaptive Gain Tuning In Process Control., Alberto Arner Rovira

LSU Historical Dissertations and Theses

Controller tuning relationships based on optimizing the response of a first order lag plus dead time process are developed for proportional-plus-integral (PI) and proportional-plus-integral-plus-derivative (PID) control algorithms. Minimum error integrals were used as criteria of performance for the feedback control loop. The relationships presented are shown to provide excellent response characteristics in particular for processes where little or no overshoot is desired. The effect of applying the proportional action to the feedback variable in a PI control algorithm is analyzed and found to provide a more consistent response to set point changes and load changes than the conventional PI algorithm, …

Ethyl Methanesulfonate (Ems) And Diethylnitrosamine (Den) Effect On Germ Cells Of Drosophila Melanogaster., Haimei Huang Jan 1981

Ethyl Methanesulfonate (Ems) And Diethylnitrosamine (Den) Effect On Germ Cells Of Drosophila Melanogaster., Haimei Huang

LSU Historical Dissertations and Theses

With autoradiography and fluorescent stain techniques, the degree of ethylation of Drosophila melanogaster sperm following treatment with (1-('3)H)-ethyl-methanesulfonate (EMS) or (2-('3)H)-diethylnitrosamine (DEN) was shown by different levels of silver grains on sperm. The degree of ethylation of sperm cells treated with the mutagen in different germ cell stages of development (sperm, spermatids, spermatocytes, or spermatogonia) was determined by varying the time of sampling. The average grains per sperm head from different samples were computed and analyzed with SAS program by the IBM 3033 computer at System Network Computer Center on the LSU campus in Baton Rouge. The sperm which originated …

Catalytic Generation Of Hydrogen From The Hydrolysis Of Sodium-Borohydride. Application In A Hydrogen/Oxygen Fuel Cell., Clifford Mark Kaufman Jan 1981

Catalytic Generation Of Hydrogen From The Hydrolysis Of Sodium-Borohydride. Application In A Hydrogen/Oxygen Fuel Cell., Clifford Mark Kaufman

LSU Historical Dissertations and Theses

Hydrogen has been promoted as the energy alternative of the future. Fuel cell utilization of hydrogen minimizes pollution while optimizing energy conversion efficiencies. Sodium borohydride has been investigated as a possible hydrogen storage and transport medium. Within the proper catalytic environment, one gram of sodium borohydride liberates almost 2.4 liters of hydrogen at a controllable rate. The effects of acids, transition metal salts, and transition metals on the hydrolysis of sodium borohydride have been mathematically quantified. Least squares analyses have reduced the data to simple combinations of algebraic expressions. Specifically, acid acceleration is subject to pseudo-first-order kinetics; equivalent acid concentrations …

Selective Antagonism Of The Error‐Increasing Effect Of Morphine By Naloxone In A Repeated‐Acquisition Task, Donald M. Thompson, Joseph M. Moerschbaecher Jan 1981

Selective Antagonism Of The Error‐Increasing Effect Of Morphine By Naloxone In A Repeated‐Acquisition Task, Donald M. Thompson, Joseph M. Moerschbaecher

Faculty Publications

Pigeons acquired a different four‐response chain each session by responding sequentially on three keys in the presence of four colors. The response chain was maintained by food presentation under a fixed‐ratio schedule. Errors produced a brief timeout but did not reset the chain. When either morphine or naloxone was administered alone, the overall response rate decreased with increasing doses. The rate‐decreasing effect was accompanied by an increase in percent errors with morphine but not with naloxone. Both effects of morphine were antagonized by doses of naloxone that were ineffective when given alone. The antagonism was selective in that naloxone (3 …

Part I. Photoelectron Spectroscopic Studies Of Amines, Alkenes, And Substituted Benzenes. Part Ii. Theoretical Studies Of Quinones., Melvin Dale Rozeboom Jan 1981

Part I. Photoelectron Spectroscopic Studies Of Amines, Alkenes, And Substituted Benzenes. Part Ii. Theoretical Studies Of Quinones., Melvin Dale Rozeboom

LSU Historical Dissertations and Theses

Methyl-substituted piperidines, oxanes, 1,3-dioxanes, and cyclohexanones were studied by photoelectron spectroscopy (pes) to determine the mechanism by which alkyl groups stabilize radical cations. Hyperconjugation was found to be the dominant mechanism, while inductive effects and charge-induced polarization were indicated to be less effective. N-Arylazacycloalkanes were studied by pes to correlate solution basicities with ionization potentials (IPs). Conformational analysis of these compounds indicated that aryl-substituted aziridines are coplanar (conjugating) in all cases studied, while ortho substituent(s) may cause rotation and loss of conjugation between the lone pair and the phenyl ring as the amine ring size is increased. N-Phenylpiperidine was indicated …

Theoretical Studies Of Nucleophilic Additions To Alkynes And Stabilities Of Anions., Robert William Strozier Jan 1981

Theoretical Studies Of Nucleophilic Additions To Alkynes And Stabilities Of Anions., Robert William Strozier

LSU Historical Dissertations and Theses

Nucleophilic additions to alkynes were investigated using ab initio molecular orbital theory. Analyses of the energetic consequences of certain molecule distortions showed that the anti selectivity of nucleophilic additions to simple alkyl, aryl, and halogenated alkynes was consistent with trans bending of acetylene. This premise was verified by considering the addition of the hydride ion to acetylene which gave a single transition state resulting from anti addition. Comparing the activation energies for hydride addition to ethylene and acetylene showed that addition to acetylene improves relative to addition to ethylene with increasing basis set sophistication. Nucleophilic addition of ammonia to cyanoacetylene …

Improved Mortality Among U.S. Blacks, 1968-1978: The Role Of Antiracist Struggle, R. Cooper, M. Steinhauer, A. Schatzkin, W. Miller Jan 1981

Improved Mortality Among U.S. Blacks, 1968-1978: The Role Of Antiracist Struggle, R. Cooper, M. Steinhauer, A. Schatzkin, W. Miller

Faculty Publications

A marked improvement in health status for black adults took place over the last decade in the United States. Life expectancy for black men increased 4.6 years between 1968 and 1978, while for black women the increase was 5.7 years. Death rates for the age group 35-74 decreased approximately 25 percent for blacks over the same period. The largest contribution to this improvement was made by cardiovascular diseases (coronary heart disease and stroke). Although similar improvement was observed in the white population, on both a percentage and absolute basis the change was greater for blacks. For the first time in …

The Origins And Development Of The Gentlemanly Ideal In The South: 1607-1865., Robert Lynn Rainard Jan 1981

The Origins And Development Of The Gentlemanly Ideal In The South: 1607-1865., Robert Lynn Rainard

LSU Historical Dissertations and Theses

The purpose of this study is to examine the origins and development of the gentleman in the South. It begins with an examination of Castiglione's The Courtier. Castiglione provided a discussion of the ideal man of Renaissance Italy. His ideal man, the courtier, possessed cultivation, character, and class. Together, these attributes made up the complete, or universal man. The Renaissance idea of the complete man profoundly influenced all later thought concerning the nature of the gentleman. The English embraced Castiglione's idea of a complete man, but they immediately adapted it to suit their own needs. The English placed much greater …

A Study Of The Relationship Of Certain Variables To Sex Characteristic Identification From The Speech Of Heterosexual And Homosexual Individuals., Norma Jean Cospelich Travis Jan 1981

A Study Of The Relationship Of Certain Variables To Sex Characteristic Identification From The Speech Of Heterosexual And Homosexual Individuals., Norma Jean Cospelich Travis

LSU Historical Dissertations and Theses

This study explored relationships of speaker sex and masculinity-femininity judgments and 12 measures of rate, fundamental frequency, and intensity from taped reading and spontaneous speech samples of female and male heterosexual and homosexual individuals. Phase One was designed to determine judgment reliability and any procedural variables that might influence judgments. Sex judgments were more accurate on the speakers' second performances. Both sex and masculine-feminine judgments were more accurate on reading than on spontaneous speech. Analysis of judgments from type-scripts of spontaneous speech yielded a significant judge sex-by-training interaction. In Phase Two, 20 listeners judged sex and masculinity-femininity from taped reading …

The Biology Of Beggiatoa., William Roy Strohl Jan 1980

The Biology Of Beggiatoa., William Roy Strohl

LSU Historical Dissertations and Theses

Part I. An accurate most-probable-number enumeration method was developed for counting the number of Beggiatoa trichomes from various freshwater sediments. The medium consisted of extracted hay, diluted soil extract, 0.05% sodium acetate, and 15-35 units per ml of catalase. The same enrichment medium, but without the acetate, was the best enrichment medium from which to obtain pure cultures. A total of thirty-two strains of Beggiatoa were isolated from seven different freshwater habitats and were separated into five groups based on several preliminary characteristics. Four of the groups contained cells with trichomes of approximately the same diameter (1.5-2.7 (mu)m) and may …

The Effect Of Attribution Training And Visual Response Cues On Persistence Following Failure., Renee Favret Jan 1980

The Effect Of Attribution Training And Visual Response Cues On Persistence Following Failure., Renee Favret

LSU Historical Dissertations and Theses

Achievement motivation and locus of control in black children attending a public school in an economically-depressed area of New Orleans, Louisiana were studied. Past research had found contradictory results regarding locus of control in students who are lacking in achievement motivation. Dweck (1975) suggested that these students were "learned helpless," i.e. they perceived their achievement outcomes to be due to external causes; that these same students could be trained to attribute outcomes to internal causes; and that this attribution training would lead to persistence following failure on achievement tasks. The present study investigated the locus of control of 130 fifth- …

A Validity Study Of The Construct "Most Highly Valued Representational System" In Human Auditory And Visual Perceptions., David E. Lange Jan 1980

A Validity Study Of The Construct "Most Highly Valued Representational System" In Human Auditory And Visual Perceptions., David E. Lange

LSU Historical Dissertations and Theses

Bandler and Grinder (1975) proposed the construct "most highly valued representational systems" to describe auditory, visual, and kinesthetic perceptual orientations among individuals. They set forth a predicate method for determining an individual's primary representational system. Contrary to Bandler and Grinder's construct, experimental evidence consistently supports the principle of visual dominance among humans. In order to test the effectiveness of Bandler and Grinder's constructs, 221 volunteers were screened by an alternate predicate method. 22 subjects were selected as "highly auditory" and 19 subjects were selected as "highly visual." These 41 subjects were asked to give their first impressions to 75 simultaneous, …

The "Southern Review": An Episode In Southern Intellectual History, 1935-1942., Ronda Cabot Tentarelli Jan 1980

The "Southern Review": An Episode In Southern Intellectual History, 1935-1942., Ronda Cabot Tentarelli

LSU Historical Dissertations and Theses

This is a study of the Southern Review, a cultural quarterly published at Louisiana State University from 1935 to 1942, and edited by Charles Pipkin, Cleanth Brooks, and Robert Penn Warren. The Review is shown to be an important part of American intellectual history in the thirties and forties, of the Southern Renascence in literature, the history of LSU, and the careers of its editors and contributors. That the Review was more than a literary quarterly (thus the label "cultural quarterly") is evident in its contents. Besides fiction, poetry, and literary criticism, the magazine published Southern, political, and philosophical articles. …

Effect Of Capillary Diameter On The Rate Of Radiation Induced Polymerization Of Acrylamide In Saline Solutions Containing Dissolved Phosphorus-32., Satyajit Verma Jan 1980

Effect Of Capillary Diameter On The Rate Of Radiation Induced Polymerization Of Acrylamide In Saline Solutions Containing Dissolved Phosphorus-32., Satyajit Verma

LSU Historical Dissertations and Theses

Radiation induced solution polymerization of acrylamide was studied at 80(DEGREES)C in tubes with diameters of 6, 2.29, 0.89 and 0.38 mm. The tubes were filled with aqueous solutions of 3% acrylamide, 10% NaCl and sufficient neutralized orthophosphoric acid to produce a specific radioactivity of 1 mCi/ml. of dissolved ('32)P. Distinctly higher initial rates of increase of solution viscosity were observed with increasing tube diameter. Kinetic studies were done also with 3% acrylamide in 0, 5 and 10% salt solutions at 81.5(DEGREES)C and 28(DEGREES)C; the reaction induced by external irradiation from ('60)Co. Other systems studied were 1 and 1.5% acrylamide in …

Sir Thomas More, Humanist And Hero: A Man For All Ages., Noel Joseph Toups Jan 1980

Sir Thomas More, Humanist And Hero: A Man For All Ages., Noel Joseph Toups

LSU Historical Dissertations and Theses

Thomas More has appeared in diverse works from the sixteenth to twentieth century; these works have usually treated him as a model of integrity and conscience whose love of truth made him a touchstone for judging a panoply of others. More's own century viewed him in conflicting ways. Tudor apologists--Hall, Holinshed, and Foxe--were critical of More's wit and treatment of heretics and deemed him prideful, whereas the recusants like Roper and Harpsfield pictured More loyal Londoner, devoted father, humanist, and man of conscience. Sixteenth century treatments culminate in those of Ro. Ba. and Munday. Munday's Thomas More, an essentially Protestant …

The Relationship Of Biorhythms To Academic Performance In Reading., Natalia Lavonne Brackin Peveto Jan 1980

The Relationship Of Biorhythms To Academic Performance In Reading., Natalia Lavonne Brackin Peveto

LSU Historical Dissertations and Theses

This study was an investigation to determine if a relationship existed between the twenty-three day physical, twenty-eight day emotional and the thirty-three day intellectual biorhythm cycles and academic achievement in reading. If a relationship existed between the learning potential of a student and the low, critical and high levels of the biorhythm cycles, instructional techniques could be designed to capitalize on the internal fluctuations of each learner. It was hypothesized that there would be a significant relationship between the academic performance of a student in reading and the high, low and critical positions of the twenty-three day physical, twenty-eight day …

Transport Properties Of Antimony In A Rod And Corbino Geometries At Low Temperatures., Mahmood Baratikhajooie Jan 1980

Transport Properties Of Antimony In A Rod And Corbino Geometries At Low Temperatures., Mahmood Baratikhajooie

LSU Historical Dissertations and Theses

An investigation of the roles of carrier diffusion and carrier-phonon drag in the thermoelectric power, the Ettingshuasen and Nernst-Ettingshausen effects was carried out on single crystals of antimony at low temperatures. Previous investigations have shown that the ideal resistivity and the high field resistivity are characterized by strong mutual drag. Here the Ettingshausen and Nernst-Ettingshausen effects were characterized by a strong simple drag. In contrast to these two extreme cases the thermoelectric power exhibited a clear admixture of the two drag conditions. Interpretation of Ettingshausen and Nernst-Ettingshausen data indicates that these two measurements are less reliable for the determination of …

Agrarian Political Economy: The Order Of Ends And Means., Andrew Warnie Foshee Jan 1980

Agrarian Political Economy: The Order Of Ends And Means., Andrew Warnie Foshee

LSU Historical Dissertations and Theses

From the earliest economic thought there has existed the notion that agriculture is the most preferred of all forms of economic activity. This preference is grounded in the belief that when agriculture is the dominant form of economic activity a set of ends will be attained which are consistent with human nature and conducive to human happiness. These are the ends of limited wealth, internal and external freedom, and piety. Writers expressing this belief were engaged in a study of political economy which was not bounded by the methodological strictures of logical positivism. For these agrarian political economists there existed …
