Determination Of The Range In Binding-Site Densities Of Rat Skin Heparin Chains With High Binding Affinities For Antithrombin., A. A. Horner, M. Kusche, U. Lindahl, C. B. Peterson Jan 1988

Determination Of The Range In Binding-Site Densities Of Rat Skin Heparin Chains With High Binding Affinities For Antithrombin., A. A. Horner, M. Kusche, U. Lindahl, C. B. Peterson

Faculty Publications

Rat skin heparin proteoglycans vary markedly in the proportions of their constituent polysaccharide chains that have high binding affinity for antithrombin. As the proportion of such chains in a proteoglycan rises, their degree of affinity for antithrombin also increases [Horner (1987) Biochem. J. 244, 693-698]. The antithrombin-binding-site densities of such chains have now been determined, by measuring heparin-induced enhancement of the intrinsic fluorescence of antithrombin and by chemical analysis for the disaccharide sequence glucuronosyl-N-sulphoglucosaminyl (3,6-di-O-sulphate), which is unique to this site in heparin [Lindahl, Bäckström, Thunberg & Leder (1980) Proc. Natl. Acad. Sci. U.S.A. 77, 6551-6555]. Antithrombin-binding-site density ranged from …


Landau-Level Width: Magnetic-Field And Temperature Dependences, Lipo Wang, R. F. Oconnell Jan 1988

Landau-Level Width: Magnetic-Field And Temperature Dependences, Lipo Wang, R. F. Oconnell

Faculty Publications

We calculate the effect of level broadening on the steady part of the magnetic moment and specific heat by deriving an analytic expression for the free energy of a two-dimensional electron gas in a uniform magnetic field, with an arbitrary Landau-level broadening and at a finite temperature. Measurements of these effects may provide a new way for gaining more information about the magnetic-field and temperature dependences of the Landau-level width. This in turn may lead to information about the density of states. In the particular case of Gaussian broadening, the broadening correction to the steady magnetic moment is as large …


Protein Solubility, In Vitro Ammonia Concentration, And In Situ Disappearance Of Extruded Whole Cottonseed And Other Protein Sources, J. A. Stutts, W. A. Nipper, R. W. Adkinson, J. E. Chandler, A. S. Achacoso Jan 1988

Protein Solubility, In Vitro Ammonia Concentration, And In Situ Disappearance Of Extruded Whole Cottonseed And Other Protein Sources, J. A. Stutts, W. A. Nipper, R. W. Adkinson, J. E. Chandler, A. S. Achacoso

Faculty Publications

Whole cottonseed extruded at temperatures (°C) and rates (kg/h) of 131, 314; 135, 182; 146, 195; and 156, 286 was evaluated by protein solubility, in vitro ammonia concentration, and in situ disappearance techniques. These techniques were used to estimate potential of extruded whole cottonseed for protein escape from the rumen. In addition, raw whole cottonseed, soybean meal, corn gluten meal, and whole cottonseed and soybean meal heated for 4 h at 127, 138, and 149°C were used for comparison. Solubility was by three methods: cold water mixed for 30 min, cold water homogenized for 5 s, and hot water refluxed …


Comprehension And Memory Of A Sexual Script: A Test Of Schema/Scripting Theory., Janis Ruth Kirsch Jan 1988

Comprehension And Memory Of A Sexual Script: A Test Of Schema/Scripting Theory., Janis Ruth Kirsch

LSU Historical Dissertations and Theses

Cognitive scientists have studied how individuals process non-sexual text, and schema/scripting theory appears to be a useful way of conceptualizing their findings. This study applied schema/scripting theory findings to sexual text and predicted that Atypical or unnecessary script actions would initially be remembered better than Typical script actions, but that over time Typical script actions would be remembered better as the generic script becomes increasingly important. The present study also incorporated findings from another line of research relevant to schema/scripting theory and predicted that the perspective taken by the reader while reading a story about a sexual encounter would affect …


The Relationship Between Learned Sexual Values And Adjustment In A Prison Setting., James William Robinson Jan 1988

The Relationship Between Learned Sexual Values And Adjustment In A Prison Setting., James William Robinson

LSU Historical Dissertations and Theses

The degree of environmental control exerted by female inmates was examined as a function of gender role identity. The sample was obtained at the Louisiana Correctional Institute for Women, the only female prison in the state. The prison environment was assumed to offer very few control options. The options studied were those under the direct authorization of the social services division of the prison, and from individuals external to the prison. It was assumed that the flexibility found in androgynous individuals would allow for a greater level of perceived control than with either the masculine or feminine gender role identity …


Global Zones Of Particle Precipitation., Muhammad Adel Miah Jan 1988

Global Zones Of Particle Precipitation., Muhammad Adel Miah

LSU Historical Dissertations and Theses

Magnetospheric particles are precipitated at low altitude all over the globe. The study of the physics of the equatorial global zone is important for geospace environment modeling, for knowing the loss processes of radiation belt particles and for the Space Station Project. The equatorial global zone was investigated by the Phoenix-1 experiment on board the S81-1 mission in May through November, 1982. The global profile of the peak flux of quasi-trapped protons follows the line of minimum magnetic field strength, with a FWHM of $\sim$13$\sp\circ$ in latitude. The pitch angle distribution anisotropy index is found to be 19 $\pm$ 2, …


Lessons Of The Masters: Social Tension As A Creative Necessity In The Fiction Of Hawthorne, James, And Joyce., Craig Arthur Milliman Jan 1988

Lessons Of The Masters: Social Tension As A Creative Necessity In The Fiction Of Hawthorne, James, And Joyce., Craig Arthur Milliman

LSU Historical Dissertations and Theses

A study of talented characters reveals that three of the most influential novelists in English dealt with the often disabling image of the artist they had inherited from their Romantic forebears by insisting on dialectical tension between the artist and society as essential to the creation of literary art. The various talented characters in Hawthorne's short fiction, such as Aylmer, Rappaccini, Oberon, the Canterbury poet, the portrait painter of "The Prophetic Pictures," the woodcarver Drowne, and Owen Warland, fail to create art unless they retain certain links with their societies of origin. This tension between artist and society appears as …


Statistical Mechanical And Experimental Studies Of Thermodynamic Behaviour Of Aromatic Hydrocarbons., Wahyudi Budi Sediawan Jan 1988

Statistical Mechanical And Experimental Studies Of Thermodynamic Behaviour Of Aromatic Hydrocarbons., Wahyudi Budi Sediawan

LSU Historical Dissertations and Theses

Statistical mechanical studies of aromatic hydrocarbon liquids have been conducted. Aromatic rings are modeled as oblate ellipsoids interacting with a modified gaussian overlap potential. This approach has been tested by molecular dynamics simulations and shown to work well for benzene and naphthalene. Addition of quadrupolar interactions further improves the results. More molecular dynamics simulation data for the gaussian overlap potential, the modified gaussian overlap potential, and a dumbell of the modified gaussian overlap potential have also been generated, to test an existing non-spherical based perturbation theory (Fischer's theory) and a newly introduced sphericalized potential method. Both approximations work qualitatively well …


The Systematics Of The Genus Thyanta Stal (Hemiptera:Heteroptera:Pentatomidae)., David Allen Rider Jan 1988

The Systematics Of The Genus Thyanta Stal (Hemiptera:Heteroptera:Pentatomidae)., David Allen Rider

LSU Historical Dissertations and Theses

The pentatomid genus Thyanta Stal is one of several large genera in the nominate subfamily and tribe. Thyanta belongs among those genera of Pentatomini lacking a spine or tubercle at the base of the third (second visible) abdominal sternite. The genus is divided into two subgenera: Phacidium Breddin, containing a single species, T. aeruginosa Berg; and the nominate subgenus, containing 36 species and one subspecies. The subgenus Thyanta is further divided into four species groups based primarily on differences and similarities in male and female genitalia. The perditor species group contains nine species and one subspecies, the maculata species group …


A Community Sample's Knowledge Of, Judgment Of, And Attitudes Toward Childrearing And Child Abuse., Harriet Schoenberg Williams Jan 1988

A Community Sample's Knowledge Of, Judgment Of, And Attitudes Toward Childrearing And Child Abuse., Harriet Schoenberg Williams

LSU Historical Dissertations and Theses

The present study addressed an important void in the literature of child abuse prevention. The challenge in empirical development of preventive education in child abuse to the public lies in the identification of specific target behaviors which are (1) related to potential child abuse, and (2) amenable to education. This investigation examined individual's expectations, attitudes and beliefs toward childrearing, as well as individual's knowledge of childrearing and behavioral child management techniques. Data generated in this study also evaluated the presence of differential judgments of child abuse in a community sample. Two hundred and eighty-two community volunteers participated in this study. …


"The Trouble I'Ve Seen": Visions And Revisions Of Bondage, Flight, And Freedom In Black American Autobiography., David Lewis Dudley Jan 1988

"The Trouble I'Ve Seen": Visions And Revisions Of Bondage, Flight, And Freedom In Black American Autobiography., David Lewis Dudley

LSU Historical Dissertations and Theses

This dissertation, an historical overview of black American autobiography from Frederick Douglass to Malcolm X, examines a recurring pattern and two related themes in the genre. Ever since the escaped slave narratives established bondage, flight, and freedom as the three-part pattern of their organization, black autobiographers have employed these same elements to tell their life stories. The creation of the free "I" is the pervasive theme of black American autobiography, freedom being won and the autobiographical self established through a symbolic struggle against and victory over a powerful father figure. This figure may be the paternalistic white culture in which …


Prediction Of Methane Solubility In Geopressured Brine Solutions By Application Of Perturbation Theory., Yangtzu Chao Jan 1988

Prediction Of Methane Solubility In Geopressured Brine Solutions By Application Of Perturbation Theory., Yangtzu Chao

LSU Historical Dissertations and Theses

The ability to predict methane solubility in underground reservoirs is essential to eventual exploitation of geothermal-geopressured reservoirs as an alternate energy source. In this study, second-order Leonard-Barker-Henderson perturbation theory was applied to brine solutions containing H$\sb2$O, CH$\sb4$, C$\sb2$H$\sb6$, CO$\sb2$, and NaCl to develop a fundamentally-based thermodynamic approach to handle more effectively the broad temperature and pressure ranges encountered in underground reservoirs, and to include the effect of the presence of various salts and other gases on methane solubility. The apparent ideal solution fugacity, f$\sbsp{i}{o\sp\prime}$, for each solute gas is proposed and developed through perturbation theory as a direct measure of …


Self-Referential Play Gone Wild: A Case For The "Roman Bourgeois" As Metafiction., Dianne Paula Guenin-Lelle Jan 1988

Self-Referential Play Gone Wild: A Case For The "Roman Bourgeois" As Metafiction., Dianne Paula Guenin-Lelle

LSU Historical Dissertations and Theses

The Roman bourgeois is a text which has resisted traditional modes of criticism, and thus it has confounded critics who simply did not know what to make of this hybrid work. It has been generally considered to be a novel which lacks coherence and literary merit, and spells the end of the cycle of seventeenth-century comic novels. This study proposes that the Roman bourgeois be considered as a metafictional text, where textual "anomalies" could be considered as "positive" attributes since they draw attention to the fictional framework and the fiction-making process of the novel. The novel operates according to the …


The Effects Of Linguistic And Non-Linguistic Context On The Deictic Interpretation Of Noun Phrases., Daniel George Foster Jan 1988

The Effects Of Linguistic And Non-Linguistic Context On The Deictic Interpretation Of Noun Phrases., Daniel George Foster

LSU Historical Dissertations and Theses

Definite noun phrases (NP's), proper names, and third person pronouns are not consistently interpreted deictically. Furthermore, these three types and first and second person pronouns, or potentially deictic NP's, whether deictic or not, may be interpreted as pertaining to the universe of discourse that each text creates, the situation of writing in which the text is created, or the attitudes of the writer towards the referent of a particular NP. Universe of discourse NP's include generic and descriptive NP's and those deictic in the most basic sense (i.e. those that point within the spatio-temporal field of the world external to …


Wade Hampton And The Rhetoric Of Race: A Study Of The Speaking Of Wade Hampton On The Race Issue In South Carolina, 1865-1878., Dewitt Grant Jones Jan 1988

Wade Hampton And The Rhetoric Of Race: A Study Of The Speaking Of Wade Hampton On The Race Issue In South Carolina, 1865-1878., Dewitt Grant Jones

LSU Historical Dissertations and Theses

This study examined the racial rhetoric of Wade Hampton with particular attention to claims that he was a moderate and sought to solve the racial problems of the period through rhetorical means. The study investigated: (1) the extent to which his speeches addressed the racial issue, (2) the consistency of his position, and (3) the nature and appropriateness of his appeals. State newspapers were examined to locate his speeches, which were categorized by period and subject. Examination of the data revealed four specific racial exigencies to which Hampton responded: (1) the loss of black labor (1865-66), (2) black suffrage (1867-68), …


Minimum Time Motion Of A Robotic Manipulator., Heon Hwang Jan 1988

Minimum Time Motion Of A Robotic Manipulator., Heon Hwang

LSU Historical Dissertations and Theses

This dissertation treats the modeling, analysis, and trajectory control of a robotic manipulator to execute specified point-to-point tasks. The relative coordinate representation of kinematic and dynamic variables is defined using vectors and matrices based on coordinate transformations. A kinematic modeling of a manipulator is performed using Denavit-Hartenberg link parameters. For given end-effector information (location and orientation), a stable and efficient iterative numerical algorithm for a joint solution is developed. A modified general Gauss elimination and a direct minimum search are combined with other refinements to yield fast convergency and stable results. This algorithm can be used as a routine solution …


A Study On The Toxicity Of Sesbania Drummondii In Chickens And Rats., Marie-Lorraine Marceau-Day Jan 1988

A Study On The Toxicity Of Sesbania Drummondii In Chickens And Rats., Marie-Lorraine Marceau-Day

LSU Historical Dissertations and Theses

A comparative study of two susceptible species, the chicken and the rat, to crude and partially purified extracts of the plant Sesbania drummondii was undertaken. Partial physical and chemical characterization of crude sesbania extracts has been accomplished including temperature and pH stability, molecular weight fractionation and high pressure liquid chromatography and thin layer chromatography retention times. The toxicity of these different fractions could be differentiated with respect to weight loss, mortality, morbidity, serum protein changes and effect on PChE (Pseudocholinesterase) activities. The results indicated that more than one toxin exists in crude extracts of this plant. The pathophysiological findings could …


Phase Space Formulation Of Quantum Mechanics And The Two Dimensional Electron Gas In A Magnetic Field., Lipo Wang Jan 1988

Phase Space Formulation Of Quantum Mechanics And The Two Dimensional Electron Gas In A Magnetic Field., Lipo Wang

LSU Historical Dissertations and Theses

In this dissertation, the theory of the phase-space formulation of quantum mechanics (PSFQM) is discussed and applied to investigations of various low-temperature properties of both two- and three-dimensional electron systems. The origin of an apparent discrepancy recently reported by others between results obtained by the PSFQM and conventional (Schrodinger) quantum mechanics is discussed. A complete agreement is arrived at here by demonstrating the correct way to use the PSFQM. A general formulation is developed, through use of the PSFQM, for determining the free energy of a Fermi gas contained in an arbitrary smooth external potential and in a weak magnetic …


The Relevance Of Visual Models In Linguistic Theory And Discourse Analysis., Alan Dee Manning Jan 1988

The Relevance Of Visual Models In Linguistic Theory And Discourse Analysis., Alan Dee Manning

LSU Historical Dissertations and Theses

Five articles explain distinct types of linguistic phenomena with visual perception analogies. Together they give indications of similar cognitive systems underlying language and vision. First, relative numbers of languages with different basic-sentence orders for Subject, Verb, and Object fall in a hierarchy: #SOV $>$ #SVO $>$ #VSO $>$ #VOS $>$ #OVS $>$ #OSV. If syntactic interpretation parallels figure/ground interpretation and semantic form parallels enclosed visual forms then that hierarchy falls out more elegantly than in generative or functionalist explanations. Second, semantic interpretation of English syntactic form (subject NP-tense Aux-predicate VP), is modeled with the Penrose …


Coulomb States In Atoms And Solids., Darren Mark Ortalano Jan 1988

Coulomb States In Atoms And Solids., Darren Mark Ortalano

LSU Historical Dissertations and Theses

In this dissertation, an empirical quantum defect approach to describe the valence excitons of the rare gas solids is developed. These Coulomb states are of s-symmetry and form a hydrogen-like series which converges to the bottom of the lowest conduction band. A non-zero quantum defect is found for all of the excitons of neon, argon and xenon. For these systems, then, there exists, in addition to the screened Coulombic component, a non-Coulombic component to the total exciton binding energy. The Wannier formalism is, therefore, inappropriate for the excitons of Ne, Ar and Xe. From the sign of the quantum defect, …


The Role Of Dietary Compliance In Survival Of Hemodialysis Patients., Laurie Ruggiero Jan 1988

The Role Of Dietary Compliance In Survival Of Hemodialysis Patients., Laurie Ruggiero

LSU Historical Dissertations and Theses

The goal of the current study was to gain knowledge of the role that dietary compliance plays in the survival of end-stage renal failure 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 survival. This knowledge would also be helpful in the identification and intervention of dietary noncompliance in hemodialysis patients. The present study investigated the relation of three commonly employed physiological parameters of dietary compliance to survival on hemodialysis and how well these dietary variables independently …


The Murder Of The Father: Readings In Sade, Balzac And Proust., Douglas Brian Saylor Jan 1988

The Murder Of The Father: Readings In Sade, Balzac And Proust., Douglas Brian Saylor

LSU Historical Dissertations and Theses

The "sadomasochistic homotext" is a text in which sadomasochism, homosexuality, the place of the father, and the perversion of language intersect. In the sadomasochistic homotext, a rebellious group seeks to usurp the authority of the father, through the perversion of language. Perversion, however, is constituted in language, and etymologies reveals that terms for homosexuality were created in the late Middle Ages and mid-nineteenth centuries. Medieval thought links homosexuality with heresy; the nineteenth century labels it "illness.". Plato's Aristophanes states that original humans were cut in half, and each half seeks the other. This division caused a disruption of language as …


Relative Isometric And Dynamic Endurance Curves For Different Muscle Groups Of The Upper Extremities., Seung Ho Yoon Jan 1988

Relative Isometric And Dynamic Endurance Curves For Different Muscle Groups Of The Upper Extremities., Seung Ho Yoon

LSU Historical Dissertations and Theses

This study analyzed the characteristics of both dynamic and isometric relative endurance curves for four different muscle groups of the upper extremities. College males (N = 56) were tested on the Cybex Isokinetic Dynamometer both isometrically and dynamically on four exercises: bench press, arm curls, shoulder internal rotation and wrist flexion. In all, eight separate exercises were examined. Each dynamic and isometric exercise bout was for 80 and 60 s, respectively and data were recorded ever 4 s. Parameters examined were Maximal Strength, Total Force Output, Relative Total (RT, TFO, divided by 80s or 60s x peak force), and Relative …


Effects Of Sex And Social Influence On Perception Of Physical Effort During Light To Heavy Work By Elite Athletes., Michael Francis Sylva Jan 1988

Effects Of Sex And Social Influence On Perception Of Physical Effort During Light To Heavy Work By Elite Athletes., Michael Francis Sylva

LSU Historical Dissertations and Theses

This study was designed to investigate the effect of sex and social influence on perception of physical effort during light or heavy work by male and female athletes. Subjects performed three submaximal trials of 27 minutes each on a cycle ergometer at 25, 50 and 70% of maximum oxygen consumption in the presence of a male coactor, a female coactor, and just riding alone. The results indicated that subjects' ratings of perceived exertion (RPE) were similar when performing at all three coactor/alone conditions. No significant sex difference in RPE was found. Thus, highly trained male and female atheletes did not …


Development Of A Computer-Integrated Manufacturing Simulation Model: A Hybrid Systems Approach., Vinay Kumar Vasudev Jan 1988

Development Of A Computer-Integrated Manufacturing Simulation Model: A Hybrid Systems Approach., Vinay Kumar Vasudev

LSU Historical Dissertations and Theses

The key to the successful "factory of the future" will be the effective coordination of managerial functions and production operations. The research presented in this dissertation addresses this "coordination" issue, especially in terms of understanding the impact and possibilities which exist in an information-rich environment. Such an environment is often referred to in the literature as being a computer-integrated manufacturing (CIM) environment. An interactive simulation modeling program, MOSES (Manufacturing Organization Simulation and Evaluation System), was developed for the purpose of describing, analyzing, and understanding such manufacturing. MOSES is a copyrighted computer program, a menu-driven, interactive, simulation modeling tool. MOSES users …


Construct Validity Of Depression And Anxiety In Pre-Adolescents And Adolescents: A Taxometric Approach., Michael P. Carey Jan 1988

Construct Validity Of Depression And Anxiety In Pre-Adolescents And Adolescents: A Taxometric Approach., Michael P. Carey

LSU Historical Dissertations and Theses

The similarities and differences of the response classes of depression and anxiety were investigated with a sample of pre-adolescents and adolescents. The subjects were 412 pre-adolescents and adolescents from a local public school and a local psychiatric hospital. All of the participants were administered a battery of self-rating on two consecutive days. Two self-ratings of depression and two anxiety measures were utilized in order to adequately sample the content domains. Additionally, self-ratings were used to assess nine related response classes (i.e, fears, social skills, major life events, activity, hopelessness, depressed mood, anxious mood, parent-adolescent conflict, and dysfunctional thoughts). All assessment …

For At-Risk Students: A Theory Based Alternative Structured School Model, Its Implementation And Evaluation., Suzan Naquin Gaston

LSU Historical Dissertations and Theses

The purpose of this study has been to design, implement, and evaluate an alternative structure to traditional schools, operationalized as the Louisiana State Youth Opportunities Unlimited School. The alternative structure of the school was based on a number of theoretical concepts. The implementation of this structure intended to increase the level of coping skills in student participants who were at risk for dropping out of high school. There were two theoretical models that influenced the design of the LSYOU school. The first model suggests that the socialization of clients is most effective in organizations that are high in scope and …


Cerebral Dominance, Language, And Emotion: A Divided Visual Field Study Of Lateral Asymmetries In The Processing Of Verbal Stimuli., Margaret Helene Launius Jan 1988

Cerebral Dominance, Language, And Emotion: A Divided Visual Field Study Of Lateral Asymmetries In The Processing Of Verbal Stimuli., Margaret Helene Launius

LSU Historical Dissertations and Theses

Thirty male and thirty female undergraduate students participated in a divided visual field study designed to examine the effects of emotional content on cerebral lateral asymmetries in the processing of verbal stimuli. The study utilized a randomized block design with a three-factor factorial arrangement of treatments. Each of the three within-subjects factors has two levels, resulting in a Task (lexical, affect-salient) x Word Type (happy, sad) x Visual Field (left, right) design. A bilateral presentation/manual response paradigm was utilized. In the lexical task, emotional words were paired with nonsense words and subjects were asked to respond to the "real English …


Semantic Encoding In Alzheimer's Disease And Multi-Infarct Dementia., Bryan Alan Bernard Jan 1988

Semantic Encoding In Alzheimer's Disease And Multi-Infarct Dementia., Bryan Alan Bernard

LSU Historical Dissertations and Theses

Episodic and semantic memory tasks were administered to patients with Alzheimer's disease (AD) and patients with multi-infarct dementia (MID). The MID group had multi-focal lesions predominantly in the subcortical regions. Episodic memory is recall of events in a particular temporal-spatial context, whereas semantic memory is "knowledge" memory regarding words and their associations. The AD and MID groups were comparable in terms of level of dementia. A control group of healthy elderly subjects was comparable to the dementia groups in regard to age and years of education. The experimental measure of semantic encoding involved presentation of six 14-word lists composed of …


An Investigation Of Legal Reasoning In Decisions To Raise The Competency To Stand Trial Motion., Lisa Myra Berman Jan 1988

An Investigation Of Legal Reasoning In Decisions To Raise The Competency To Stand Trial Motion., Lisa Myra Berman

LSU Historical Dissertations and Theses

Competency to stand trial evaluations lack an operational criterion for evaluation by mental health professionals. This dissertation investigated the legal reasoning behind the decision to raise the competency motion, to highlight variables which might contribute to such a definition. In the first study, 224 defendants in the Baton Rouge Public Defender's Office were described by the legal investigators using endorsements on the Pre Trial Behavior Checklist, a list of descriptors adapted from competency research conducted by Roesch and Golding (1980). A discriminant analysis using all the PTBC subscales predicted the raising of the motion at a rate greater than chance. …
