Extended Loops: A New Arena For Nonperturbative Quantum Gravity, Cayetano Di Bartolo, Rodolfo Gambini, Jorge Griego, Jorge Pullin Jan 1994

Extended Loops: A New Arena For Nonperturbative Quantum Gravity, Cayetano Di Bartolo, Rodolfo Gambini, Jorge Griego, Jorge Pullin

Faculty Publications

We propose a new representation for gauge theories and quantum gravity. Alternatively, it can be viewed as a new framework for doing computations in the loop representation. It is based on the use of a novel mathematical structure that extends the group of loops into a Lie group. This extension allows the use of functional methods to solve the diffeomorphism and Hamiltonian constraint equations. It puts in a precise framework some of the regularization problems of the loop representation. It has practical advantages in the search for quantum states. Making use of it we are able to find a new …

Late-Time Behavior Of Stellar Collapse And Explosions. Ii. Nonlinear Evolution, Carsten Gundlach, Richard H. Price, Jorge Pullin Jan 1994

Late-Time Behavior Of Stellar Collapse And Explosions. Ii. Nonlinear Evolution, Carsten Gundlach, Richard H. Price, Jorge Pullin

Faculty Publications

We compare the predictions of linearized theory for the radiation produced in the collapse of a spherically symmetric scalar field with a full numerical integration of the Einstein equations. We find power-law tails and quasinormal ringing remarkably similar to predictions of linearized theory even in cases where nonlinearities are crucial. We also show that power-law tails develop even when the collapsing scalar field fails to produce a black hole. © 1994 The American Physical Society.

Colliding Black Holes: The Close Limit, Richard H. Price, Jorge Pullin Jan 1994

Colliding Black Holes: The Close Limit, Richard H. Price, Jorge Pullin

Faculty Publications

The problem of the mutual attraction and joining of two black holes is of importance as both a source of gravitational waves and as a testbed of numerical relativity. If the holes start out close enough that they are initially surrounded by a common horizon, the problem can be viewed as a perturbation of a single black hole. We take initial data due to Misner for close black holes, apply perturbation theory, and evolve the data with the Zerilli equation. The computed gravitational radiation agrees with and extends the results of full numerical computations. © 1994 The American Physical Society.

Chromosome And Sperm Size Of Holsteins With And Without Bovine Leukocyte Adhesion Deficiency, H. C. Steinholt, J. E. Chandler, R. A. Baron, R. W. Adkinson

Faculty Publications

The objective was to evaluate bull differences in chromosomal and spermatozoal areas related to the occurrence of the bovine leukocyte adhesion deficiency syndrome. Lymphocyte chromosomes from 30 Holstein bulls and 2 Holstein heifers were measured using image analysis and computer-enhanced video-microscopy. Spermatozoal head areas from 29 of the 30 bulls were measured. Autosomal rank was based on decreasing area. Average total autosomal areas were not the same across bulls. One group of bulls had significantly smaller average chromosomal areas than the others; this group carried bovine leukocyte adhesion deficiency syndrome. Area measures of spermatozoal heads showed that bulls with bovine …

A 6200-Year Environmental History Of The Pearl River Marsh, Louisiana., Xu Li Jan 1994

A 6200-Year Environmental History Of The Pearl River Marsh, Louisiana., Xu Li

LSU Historical Dissertations and Theses

An 8.81 m sediment core from the fresh marsh area of the Pearl River delta was examined for pollen, diatom, and organic content, to reconstruct the history of the late-Holocene environmental changes. The data show that prior to 5900 years B.P., the coring site was occupied by a swamp forest. Afterwards, the swamp was replaced by a marsh vegetation as a result of postglacial transgression. Since 5900 years B.P. the marsh has remained brackish for most of the time, characterized by abundant marine diatoms and brackish marsh pollen. However, the brackish water environment was interrupted at least two times when …

File Allocation And Join Site Selection Problem In Distributed Database Systems., Pil Kyo Seo Jan 1994

File Allocation And Join Site Selection Problem In Distributed Database Systems., Pil Kyo Seo

LSU Historical Dissertations and Theses

There are two important problems associated with the design of distributed database systems. One is the file allocation problem, and the other is the query optimization problem. In this research a methodology that considers both these aspects is developed that determines the optimal location of files and join sites for given queries simultaneously. Using this methodology, three different mixed integer programming models that describe three cases of the file allocation and join site selection problem are developed. Dual-based procedures are developed for each of the three mixed integer programming models. Extensive computational testing is performed which shows that the dual-based …

Eric Voegelin's Mystical Epistemology And Its Influence On Ethics And Politics., Charles Warren Burchfield Jan 1994

Eric Voegelin's Mystical Epistemology And Its Influence On Ethics And Politics., Charles Warren Burchfield

LSU Historical Dissertations and Theses

The primary purpose of this dissertation is to examine and analyze Eric Voegelin's theory of knowledge, and to see what implications it has on his theories of ethics and politics. The profundity of Voegelin's epistemological search and recovery is apparent when placed in the context of his disillusionment with and resistance to the dominant epistemology of his day, namely, positivism. Through a recovery and restoration of the symbolizations of classical and Christian philosophy, Voegelin searches for and finds experiential knowledge which is gained through faith in search of understanding (fides quaerens intellectum), which brings about a vision of the whole …

The Dimensionality Of Factors Underlying Satisfaction With Continuing Care Retirement Communities., Aimee Desobry Prawitz Jan 1994

The Dimensionality Of Factors Underlying Satisfaction With Continuing Care Retirement Communities., Aimee Desobry Prawitz

LSU Historical Dissertations and Theses

The purpose was to develop and test a model to predict satisfaction with consumer selection of continuing care retirement communities (CCRCs). The family resource management conceptual framework of Deacon and Firebaugh (1988) provided the theoretical base for development of the proposed model. Another area of study, consumer behavior, was drawn upon to find pertinent indicators for the decision-making component of the model. Constructs of the Engel, Blackwell and Miniard (1990) consumer behavior model were incorporated to represent the managerial aspect of the family resource management model. The model was tested by applying it to the CCRC selection process of consumers. …

Pairing And Quadrupole Interactions In The Pseudo-Su(3) Shell Model., Chairul Bahri Jan 1994

Pairing And Quadrupole Interactions In The Pseudo-Su(3) Shell Model., Chairul Bahri

LSU Historical Dissertations and Theses

Pseudo-SU(3) symmetry along with its simple symmetry-preserving and symmetry-breaking interactions is presented. This symmetry is a direct consequence of pseudo-spin symmetry which can be clearly seen in a single-particle shell model picture of heavy (A $\sbsp{\sim}{>}$ 100) atomic nuclei. Good pseudo-spin symmetry is shown to have its origin at a more fundamental level by considering relativistic mean field results for the strength parameters of the spin-orbit and the orbit-orbit interactions. As long as the residual interaction is a pseudo-spin scalar interaction, the many-particle extension of the single-particle picture is also expected to have,good total pseudo-spin symmetry. The quadrupole-quadrupole interaction …

Effects Of Dietary Boron In Rats Fed A Vitamin D-Deficient Diet, J. N. Dupre, M. J. Keenan, M. Hegsted, A. M. Brudevold Jan 1994

Effects Of Dietary Boron In Rats Fed A Vitamin D-Deficient Diet, J. N. Dupre, M. J. Keenan, M. Hegsted, A. M. Brudevold

Faculty Publications

Although boron has long been known to be a required nutrient for plants, it was not until recently that there was any suggestion of a nutritional requirement for animals and humans. Addition of boron to the diet of vitamin D-deficient chicks indicated that boron may play a role in animal nutrition. Studies with rats have demonstrated that supplemental dietary boron has most marked effects when the diet is deficient in known nutrients. We observed higher apparent-balance values of calcium, magnesium, and phosphorus for rats fed a vitamin D-deprived diet with dietary supplemental boron (2.72 ppm), than for rats fed the …

Modeling Transport Of Non Aqueous Wastes In Unsaturated Soils., Dharmesh Vinaychandra Doshi Jan 1994

Modeling Transport Of Non Aqueous Wastes In Unsaturated Soils., Dharmesh Vinaychandra Doshi

LSU Historical Dissertations and Theses

In evaluating risks associated with chemical spills on the ground surface or leaks from underground storage tanks, it is required to know the extent and degree of contamination in the subsurface. In many cases pure organics are spilled and due to their low miscibility with water they remain pure or concentrated for some distance or time from the source. This dissertation is aimed at developing a model of the multiphase (air, water, organic) migration processes. The particular focus is on modeling organic infiltration in the unsaturated zone where the transport is largely vertical. Sand-column experiments using a variety of immiscible …

Murderous Historian: Henry Adams, Modernity, And The Problem Of Subjectivity. (Volumes I And Ii)., Martha Moseley Regalis Jan 1994

Murderous Historian: Henry Adams, Modernity, And The Problem Of Subjectivity. (Volumes I And Ii)., Martha Moseley Regalis

LSU Historical Dissertations and Theses

This study traces Henry Adams's evolution from an enlightenment historian to a prescient postmodern theorist, and explores how he came to regard his own intellectual history as paradigmatic of the arc of subjectivity in the West from the Middle Ages to Nietzsche and Bergson. Adams was a self-conscious philosophical nominalist, and he believed that his radical doubts about the capacity of language for embodying meaning had their origin in medieval nominalism. Adams found the seeds of modernity and the problem of subjectivity which were the focus of his own musings on the nature of the self and history in Abelard …

Narrative And Representation In French Colonial Literature Of Indochina., Jean Marie Turcotte Walls Jan 1994

Narrative And Representation In French Colonial Literature Of Indochina., Jean Marie Turcotte Walls

LSU Historical Dissertations and Theses

This study focuses on the establishment and critical legitimation of colonial literature as a genre during the period of intense colonial development in France from approximately 1871-1930. Fictional accounts of the French involvement in Indochina are used to examine the paradoxes of colonial representation. Les Civilises by Claude Farrere, Le Kilometre 83 by Henri Daguerches, and Sur la Route Mandarine by Roland Dorgeles are examined in terms of the inconsistencies and contradictions which emerge from the efforts of the narrator/colonizer to inscribe and represent the other in a composite colonial system. These texts are examined in terms of three textual …

Use Of Uncertainty Methodology In Identification And Classification Of Soils Based Upon Cpt., Zhongjie Zhang Jan 1994

Use Of Uncertainty Methodology In Identification And Classification Of Soils Based Upon Cpt., Zhongjie Zhang

LSU Historical Dissertations and Theses

The current Cone Penetration Test (CPT) soil engineering classifications have two kinds of uncertainties: randomness and fuzziness. Research indicates that possible solutions to these uncertainties can only be worked out through modeling them. Therefore, a systematic investigation is performed and some preparative tasks are done in advance. First, an efficient soil classification index, U, is defined and several CPT soil classification charts are simplified accordingly. Second, a moving window approach based upon an Intraclass Correlation Coefficient (ICC) to determine normal soil behavior units is adopted so that a correlation between soil types and soil behavior units can be established. Based …

Gaseous Exchange And Wetland Plant Response To Soil Redox Conditions., Hillarius Kodzo Kludze Jan 1994

Gaseous Exchange And Wetland Plant Response To Soil Redox Conditions., Hillarius Kodzo Kludze

LSU Historical Dissertations and Theses

Laboratory studies pertaining to effects of soil redox conditions on gas exchange and plant responses were undertaken. A colorimetric method for assaying O$\sb2$ concentration in the root rhizosphere was used to quantify radial O$\sb2$ loss from plant roots. The oxidizing power of seven rice cultivars, grown under aerobic and hypoxic conditions, was measured colorimetrically with titanium-citrate solution. Oxygen release rate was calculated by extrapolation of measured absorbance to standard curves after placing plant roots in the solution for 6 h. Since Ti$\sp{3+}$ ions readily react with O$\sb2$ as it is released from roots, the technique provides a sensitive measurement of …

Enzymatic Hydrolysis Of Crawfish Processing By-Products For Bioflavor Production., Hyung-Hee Baek

LSU Historical Dissertations and Theses

Crawfish processing by-products (CPBs) were hydrolyzed using protease to evaluate the potential for bioflavor production. Ten commercial proteases (neutral and alkaline) were tested at both 37$\sp\circ$C and their optimum temperatures using CPBs as substrate. Of these, APL-440 was selected for enzymatic hydrolysis of CPBs on the basis of activity per cost. Response surface methodology (RSM) was used to optimize the hydrolysis of CPBs using APL-440. Optimum hydrolysis conditions for enzymatic hydrolysis of CPBs with APL-440 were determined to be pH 8-9, 65$\sp\circ$C, 2.5 hr reaction time, 75% substrate concentration, and 0.3% APL-440. Two types of CPBs (composite and claw) were …

May I Speak? A Hermeneutic Conversation Of Secondary Students' Experiences Of Curriculum., Kathryn M. Benson

LSU Historical Dissertations and Theses

The purpose of this study is to allow for a phenomenological, hermeneutic treatment of students' experiences of curriculum. The foci of this study are to stake a claim for the students' situated positions within educational research and to provide spaces within academic research where students' voices might be heard concerning their experiences of curriculum. After posing the problem of a lack of students' perspectives in educational research, I present the study's methodology: a blending of Gadamer's philosophical hermeneutics and van Manen's hermeneutic phenomenology. Terms which seem salient to the study are as follows: silence, voice, conversation, and experience. Categorical thematic …

"Rag-Tag And Bob-Ends Of Old Stories": Biblical Intertextuality In Faulkner, Hurston, Wright, And O'Connor., Timothy Paul Caron Jan 1994

"Rag-Tag And Bob-Ends Of Old Stories": Biblical Intertextuality In Faulkner, Hurston, Wright, And O'Connor., Timothy Paul Caron

LSU Historical Dissertations and Theses

Liqht in August, Moses, Man of the Mountain, Uncle Tom's Children, and Wise Blood all borrow from the South's religious traditions. Recognizing the authority given to the Book, Faulkner, Hurston, Wright, and O'Connor invoke and re-read its central stories, characters, and tropes in order to voice their individual contributions to the South's intra-cultural conversation on race. In various ways, each work claims the necessity of the South to revitalize its practice of biblical interpretation. All of these texts comment upon the South's racial struggles over exactly how the Bible was to be interpreted: is it a book to aid in …

Neogene Extension And Regional Rotation Of The Central Mojave Desert, California., Timothy Michael Ross Jan 1994

Neogene Extension And Regional Rotation Of The Central Mojave Desert, California., Timothy Michael Ross

LSU Historical Dissertations and Theses

The southwest Cady Mountains of San Bernardino County, California, contain key relationships which allow separation of the timing of early Miocene detachment-style extension and vertical-axis clockwise rotation in the Mojave Desert. The rock succession consists of a pre-Tertiary granitic basement overlain by three successive volcanic and volcaniclastic units of early to middle Miocene age referred to informally as the formation of Poe, the formation of Troy Peak and the "Barstow Formation". Deposition of the volcanic upper Oligocene/lower Miocene formation of Poe was accompanied by extension and tilting, facilitated by faults which do not cut the unconformably overlying formation of Troy …

Literature Of Protest: The Franco Years., Margaret Carmell Gonzalez Jan 1994

Literature Of Protest: The Franco Years., Margaret Carmell Gonzalez

LSU Historical Dissertations and Theses

This study examines the relationship between Spanish literature and political opposition under the Franco regime. Chapter 1 introduces the concept of a political discourse that characterizes a historical era, specifically addressing that of the Franco era in Spain. Directly linked to the idea of a political discourse is the theory of a literary generation, united by the common experiences or characteristics of a specific time period, such as those of the Franco regime. Together, these two concepts helped establish a foundation for the transition to democracy in Spain. Chapter 2 discusses the mythic foundations of Spanish culture in general, and …

Instrumental And Sensory Characterization Of The Flavor Of Blue Crab (Callinectes Sapidus) Meat And Processing By-Product., Hau Yin Chung Jan 1994

Instrumental And Sensory Characterization Of The Flavor Of Blue Crab (Callinectes Sapidus) Meat And Processing By-Product., Hau Yin Chung

LSU Historical Dissertations and Theses

Blue crab (Callinectes sapidus) meat and its processing by-product (CPB) were characterized by instrumental, olfactometric, and sensory techniques to determine the usefulness of CPB as a feed stock for flavor recovery. Instrumental analysis with gas chromatography/mass spectrometry (GC/MS) and gas chromatography/Fourier transformed infrared spectroscopy (GC/FTIR) allowed for the identification of 77 and 80 compounds in claw meat and CPB, respectively. Fifty-five compounds were found common to both samples, suggesting that CPB could be a good source for flavor recovery. Quantitatively, trimethylamine (TMA), alkanes (C15-C17, C19), and indole were high ($>$50ng/g) in claw meat while TMA, carbon disulfide, dimethyltrisulfide, alkanes …

A Rhetorical Analysis Of Selected Pro-Slavery Sermons By Presbyterian Clergy In The Antebellum South., Russell Pepper Dill Jan 1994

A Rhetorical Analysis Of Selected Pro-Slavery Sermons By Presbyterian Clergy In The Antebellum South., Russell Pepper Dill

LSU Historical Dissertations and Theses

This study investigated the pro-slavery rhetoric of selected Presbyterian ministers in the antebellum South from 1843 to 1861. The first half of the Nineteenth Century was marked by significant social, political, and religious events to which Southern Evangelical Protestantism (i.e., Baptists, Methodists, and Presbyterians) was forced to respond. Representative of Southern Evangelical Protestantism, Presbyterian clergy had a reputation for education, influence, and pulpit eloquence. As evidence of their puissance and persuasion, the sermons in this study were circulated in print, most of them at the request of the local communities and newspapers of the day. A synthesis of two methodologies …

Elevation Of The Hatching Envelope In Penaeidea Shrimp: Morphology And Assembly., Patricia Stoops Glas Jan 1994

Elevation Of The Hatching Envelope In Penaeidea Shrimp: Morphology And Assembly., Patricia Stoops Glas

LSU Historical Dissertations and Theses

The appearance of extracellular coats around "eggs" are associated with activation of the oocytes. This coat, termed fertilization envelope (sea urchins), chorion (fish), zona pellucida (mammals), capsule (crab) or hatching envelope (HE) (shrimp) serves as a polyspermy block (Wasserman, 1982) or microenvironment protecting the egg from bacteria or other hostile elements (Kudo and Inoue, 1989; Kudo and Teshima, 1991; Kudo, 1992; Epel, 1993). HE assembly is described for penaeoid shrimp (Lynn, et al., 1991) and is, in contrast to many systems, a fertilization independent event. However, the mechanisms of assembly appear similar to extracellular coat formation in other animal systems …

Temporal And Synoptic Analyses Of Heavy Rainfall In The Southeastern United States., Barry David Keim Jan 1994

Temporal And Synoptic Analyses Of Heavy Rainfall In The Southeastern United States., Barry David Keim

LSU Historical Dissertations and Theses

The abundance of recent heavy rainstorms in the southeastern United States has raised concerns that excessive rainstorms may be increasing in frequency and magnitude across the region. For this reason, the heavy rainfall climatology was examined to determine whether long-term trends exist within the historic climate record. In addition, the synoptic conditions leading to these events were examined. The synoptic weather patterns that generated storm events over a 75 mm (3 inches) threshold were classified using an all-inclusive manual weather typing system. Heavy rainfall events in the region were generated primarily by frontal weather systems (79 percent) followed by tropical …
