In Vitro Regeneration And Protein Changes Associated With Two Cultivars Of Agrostis Palustris Huds. Cultured Under High Sodium-Chloride Conditions., John Casper Hovanesian Jan 1987

In Vitro Regeneration And Protein Changes Associated With Two Cultivars Of Agrostis Palustris Huds. Cultured Under High Sodium-Chloride Conditions., John Casper Hovanesian

LSU Historical Dissertations and Theses

Calli from 'Penneagle' and 'Seaside' creeping bentgrass (Agrostis palustris Huds.) were selected for enhanced ability to proliferate on media supplemented with 514 mM NaCl. Based on dry matter production and vigor, growth of plants regenerated from NaCl-adapted calli of both cultivars in saline hydroponic nutrient medium, was superior to that of plants regenerated from non-adapted calli. At 257 mM NaCl, plants from NaCl-sensitive calli died or were unable to produce measurable dry matter whereas plants from NcCl-adapted calli grew well. Growth of plants from NaCl-adapted calli was inhibited at 340 mM NaCl. At 514 mM NaCl, resistant plants no longer …

The Effect Of Vocal Modeling On Pitch-Matching Accuracy Of Children In Grades One Through Six., Georgia A. Green Jan 1987

The Effect Of Vocal Modeling On Pitch-Matching Accuracy Of Children In Grades One Through Six., Georgia A. Green

LSU Historical Dissertations and Theses

The purpose of this study was to investigate the effect of adult female, adult male, and child vocal modeling on the pitch-matching accuracy of children in grades one through six. Because singing is a basic component of the elementary music curriculum and is a skill which a child will continue to use throughout his/her life, it is important to determine how a child can most successfully develop and use his/her singing voice. Existing literature indicates that those factors which most directly affect a child's singing ability are maturation, auditory discrimination, vocal range, and vocal modeling. Conflicting results exist as to …

The Louisiana Cooperative Extension Service: A Descriptive History Of Its Origin And Development. (Volumes I And Ii)., Edwin Clark Forrest Jr Jan 1987

The Louisiana Cooperative Extension Service: A Descriptive History Of Its Origin And Development. (Volumes I And Ii)., Edwin Clark Forrest Jr

LSU Historical Dissertations and Theses

This dissertation studies the conditions which brought the Louisiana Cooperative Extension Service (LCES) into existence in 1914 and which have sustained it for over 70 years. The U.S. Department of Agriculture estimates that 40 percent of Russia's population consists of farmers and that approximately 70 percent of China's population are farmers. The significance of these figures in relation to productivity is apparent when contrasted with the United States farm population of 2 percent. The current high level of production in American agriculture, sustained by such a small percentage of the population, is not an accident, as Professor Roy V. Scott, …

The Rational Overhauser: An Interpolating Rational Cubic Curve., Jeffrey Neil Jortner Jan 1987

The Rational Overhauser: An Interpolating Rational Cubic Curve., Jeffrey Neil Jortner

LSU Historical Dissertations and Theses

A rational interpolating cubic curve which implicitly maintains first order geometric continuity in splines has been developed. The curve is formed by blending two rational quadratic curves. Since the blending method used was originally introduced by Overhauser, this curve is referred to as the Rational Overhauser (Rover) curve. The curve formulation utilizes four shape factors to provide control of the curve. A geometrical and analytical interpretation of these shape factors and their relationship to each other is discussed. Procedures for representing conic sections using the rational Overhauser curve are presented. Also included are techniques for mapping between the Rover curve …

Parameters Of Peat Formation In The Mississippi Delta (Holocene)., Elisabeth Catharina Kosters Jan 1987

Parameters Of Peat Formation In The Mississippi Delta (Holocene)., Elisabeth Catharina Kosters

LSU Historical Dissertations and Theses

The Mississippi Delta consists of six major Holocene deltaic complexes, that each had a life-span of about 1500 years. Emphasis of this study is on autochthonous peats of Barataria Basin, a large-scale interdistributary basin, between levees of the LaFourche and St. Bernard/Plaquemine deltas. A 6 m. thick set of lithostratigraphic units constitutes the aggradational basin-fill. Organic-rich beds occur in three phases, each representing an accumulating period that was interrupted by subsidence and the influx of detrital clastics from renewed nearby fluvio-deltaic sedimentation. Peats accumulated in eutrophic, non-domed environments in fresh water swamps and (often floating) marshes and average 81.7% organic …

The Rabbit Phosphofructokinase Genes: Molecular Cloning, Sequencing And Characterization., Ming-Ching Kao Jan 1987

The Rabbit Phosphofructokinase Genes: Molecular Cloning, Sequencing And Characterization., Ming-Ching Kao

LSU Historical Dissertations and Theses

Two rabbit phosphofructokinase (PFK) genomic clones were isolated from a lambda Charon 4A rabbit liver DNA library. A 180-bp rabbit muscle PFK cDNA encoding 60 amino acids in the C-terminal region of RM-PFK was used as a probe. By using the shotgun subcloning approach, we cloned, sequenced and characterized two rabbit PFK genomic clones. The two clones overlapped and represented a total length of 17 kb which encoded the entire RM-PFK protein. The organization of this gene was elucidated by restriction mapping and DNA sequencing. It contains 22 exons, ranging in size from 45 to 190 bp, separated by 21 …

Management Of Rhizoctonia Aerial Blight Of Soybean And Biology Of Sclerotia Of Rhizoctonia Solani Kuhn (Louisiana)., Gary Fischer Joye Jan 1987

Management Of Rhizoctonia Aerial Blight Of Soybean And Biology Of Sclerotia Of Rhizoctonia Solani Kuhn (Louisiana)., Gary Fischer Joye

LSU Historical Dissertations and Theses

Rhizoctonia Aerial Blight (RAB) has caused severe damage on susceptible soybean cultivars throughout the southern soybean growing areas in Louisiana and the southeastern United States. During the 1983, 1984, and 1985 growing seasons, several greenhouse and field experiments were conducted to determine the influence of cultural practices (row spacings, plant populations, potassium fertilizer rates, and fungicide treatments) on RAB. A row spacing of 25 cm resulted in higher yields than row spacings of 50, 75, or 100 cm, regardless of disease rating. After the crop canopy had reached its maximum density, disease ratings were not significantly different between row spacings …

Spacing Of Repetitions And Contextual Interference Effects In Motor Skill Learning., Harry John Meeuwsen Jan 1987

Spacing Of Repetitions And Contextual Interference Effects In Motor Skill Learning., Harry John Meeuwsen

LSU Historical Dissertations and Theses

Three experiments are reported that examined the possibility that the contextual interference effect in motor skill learning is a variation of a multiple trial spacing of repetitions effect. Specifically, the question why a non-spaced condition in a spacing of multiple trials motor learning paradigm has not produced predicted retention deficits. Subjects in all experiments learned to perform a simple motor skill in a criterion movement time. Experiments 1 and 2 examined why spacing of multiple trials did not produce expected retention performance benefits in previous spacing experiments. The results of Experiment 1 and 2 showed that the randomness of the …

Metal Behavior In Acid Sulfate Soils Of Thailand., Philip Alderson Moore Jr Jan 1987

Metal Behavior In Acid Sulfate Soils Of Thailand., Philip Alderson Moore Jr

LSU Historical Dissertations and Theses

Metal availability and uptake by rice in flooded acid sulfate soils from the Central Plains region of Thailand were evaluated under field, growth chamber and greenhouse conditions. The results found in this study indicated that Fe$\sp{2+}$ activities are seldom in equilibrium with pure Fe solid phases in these soils. This was believed to be due to (1) transient redox conditions, (2) the presence of ill-defined ferric oxides, and/or (3) cation exchange reactions. Equilibria calculations also indicated that these soils were undersaturated with respect to most Ca, Mg, and Mn solid phases, and their activities were believed to be controlled by …

Managerial Reward Allocations: A Test Of Freedman And Montanari's Model., Jeanne Michele Russell Jan 1987

Managerial Reward Allocations: A Test Of Freedman And Montanari's Model., Jeanne Michele Russell

LSU Historical Dissertations and Theses

A part of Freedman and Montanari's (1980) managerial reward allocation model was examined in the present study. The hypotheses focused on two categories of antecedent variables, organizational and managerial, and on the dependent variable of choice of mode of reward allocation. They were tested utilizing questionnaire data collected from 155 managers in eleven financial institutions. The only hypothesis that was confirmed related managerial pay increase goals to the choice of reward allocation mode. In order to test the relative importance of different managerial and organizational variables in determining the mode of reward allocation mode, stepwise regression analyses were performed for …

Abstract Wiener Space Approach To Hida Calculus (Brownian Motion)., Youngsook Lee Shim Jan 1987

Abstract Wiener Space Approach To Hida Calculus (Brownian Motion)., Youngsook Lee Shim

LSU Historical Dissertations and Theses

Let $\cal S$ be the Schwartz space of rapidly decreasing real functions on ${\rm I\!R.}$ The dual space ${\cal S}\sp\ast$ of $\cal S$ consists of tempered distributions. The inclusion maps ${\cal S}\subset{\rm L\sp2(I\!R)}\subset{\cal S}\sp\ast$ are continuous. Hida's theory of Brownian and generalized Brownian functionals is the study of functionals defined on ${\cal S}\sp\ast.$ In this dissertation, the triple ${\cal S}\subset{\rm L\sp2(I\!R)}\subset{\cal S}\sp\ast$ is replaced by an abstract Wiener space ${\rm B}\sp\ast$ $\subset$ H $\subset$ B and an abstract version of Hida's theory is developed. The Gaussian measure on ${\cal S}\sp\ast$ in Hida's calculus is replaced by the standard Gaussian measure …

Applications Of Syntax And Pragmatics To Research In Writing., Kathryn Louise Riley Jan 1987

Applications Of Syntax And Pragmatics To Research In Writing., Kathryn Louise Riley

LSU Historical Dissertations and Theses

Researchers in writing have expressed disillusionment with transformational-generative syntax over the past decade. Such disillusionment is caused partly by the different research goals and assumptions about language held by researchers in syntax and those in writing, and partly by unrealistic expectations about the pedagogical usefulness of syntactic theory. However, rather than abandoning the study of linguistics, writing specialists may benefit by reexamining the relation between their field and that of linguistics. First, researchers in writing should distinguish more clearly between applied research and pedagogy. Syntactic theory can be used to explain and analyze certain structural phenomena in student writing, even …

An Investigation Of The Inference And Mapping Components Of The Componential Theory Of Analogical Reasoning., Catherine Sheard Jan 1987

An Investigation Of The Inference And Mapping Components Of The Componential Theory Of Analogical Reasoning., Catherine Sheard

LSU Historical Dissertations and Theses

Sternberg's componential theory of analogical reasoning (1977) provides a series of steps that may be followed in order to solve analogies. According to Sternberg, when given a simple analogy (in the form A:B::C: (D$\sb1$, D$\sb2$, D$\sb3$)) the reasoner: (a) encodes the terms of the analogy, (b) infers the relation between A and B, (c) maps the relation between A and C, (d) applies a relation analogous to the inferred one from C to each answer option, choosing the closer option, and (e) responds. The purpose of this research was to further investigate the inference and mapping processes of the componential …

Raison D'Etat And The American Philosophy Of Realism In World Affairs. (Volumes I And Ii)., Gregory T. Russell Jan 1987

Raison D'Etat And The American Philosophy Of Realism In World Affairs. (Volumes I And Ii)., Gregory T. Russell

LSU Historical Dissertations and Theses

The purpose of this study is to determine the extent to which the heritage of political thought shaping European raison d'etat is significant for the theory and practice of post-World War II realism in American foreign policy. Analysis is guided by the hypothesis that the response of postwar realists to the issues raised by an interdependent multistate system differs from the traditional rationale of raison d'etat intended for a Eurocentric international society characterized by common diplomatic objectives and values. Consideration is given to how the continental legacy has been modified and adapted by realist spokesmen to the exigencies of America's …

Classical And Statistical Thermodynamics Of Gas Solubility In Polar Fluids., Christopher Paul Williams Jan 1987

Classical And Statistical Thermodynamics Of Gas Solubility In Polar Fluids., Christopher Paul Williams

LSU Historical Dissertations and Theses

The solubilities of argon and of three binary gas mixtures of nitrogen and methane, 25%CH$\sb 4$ - 75%N$\sb 2$, 50%CH$\sb 4$ - 50%N$\sb 2$ and 75%CH$\sb 4$ - 25%N$\sb 2$, in water have been measured at a temperature of 323K for pressures up to 124.1 MPa. The data have been correlated using the established forms of the Krichevsky-Kasarnovsky and Krichevsky-Ilinskaya equations and are in agreement with previous studies. The performance of the Krichevsky-Ilinskaya equation has been improved by using Wilson's equation in place of the two-suffix Margules equation to predict the non-ideality associated with the solute gas in the solution. …

Insulin Receptors Of Erythrocytes And Liver Membranes In Dogs., Karen Johnson Wolfsheimer Jan 1987

Insulin Receptors Of Erythrocytes And Liver Membranes In Dogs., Karen Johnson Wolfsheimer

LSU Historical Dissertations and Theses

Insulin receptor assays using canine liver membranes and erythrocytes were validated for use in evaluating insulin receptor binding parameters within a healthy population of dogs. Association, dissociation, saturability and specificity were demonstrated for insulin receptors of canine liver membranes and erythrocytes. Assay precision was evaluated by measuring interassay coefficient of variation (liver membrane = 25.0%; erythrocytes = 9.3%). Because the number of high-affinity receptor sites and high-affinity K$\sb{\rm D}$ were determined using physiological concentrations of insulin, they were considered to be more physiologically important than the total number of receptor sites, low-affinity K$\sb{\rm D}$ and Ke, which were derived using …

Design And Evaluation Of Gas-Condensate Wells Using The Systems Analysis Approach., David Stephen Sutton Jan 1987

Design And Evaluation Of Gas-Condensate Wells Using The Systems Analysis Approach., David Stephen Sutton

LSU Historical Dissertations and Theses

The use of Systems Analysis for designing and evaluating wells flowing hydrocarbon mixtures seems to create no computational problems when considering the inflow components, i.e. reservoir and perforations. However, when a gas-condensate system is considered, the outflow component calculating the total pressure losses in the tubing creates a computational problem. This computational problem involves the estimation of the phase properties of the gas-condensate fluid. Thus, the fluid system undergoes phase changes as it moves up the tubing. Attempts by other authors have been made to overcome this by either using a single-phase or two-phase flow model. The single-phase flow model …

Feeding And Microspatial Relationships Of Meiobenthic Harpacticoid Copepods With Microbial Flora., Alan William Decho Jan 1987

Feeding And Microspatial Relationships Of Meiobenthic Harpacticoid Copepods With Microbial Flora., Alan William Decho

LSU Historical Dissertations and Theses

Feeding processes and their relationship to microspatial patterns were examined for several harpacticoid species. Field evidences and laboratory radiolabel experiments suggest that diatoms comprise a major portion of the food resources ingested by harpacticoids. Bacteria and mucus-exopolymer secretions (associated with the bacteria and diatoms) are also ingested, coincidently while ingesting diatoms. Also, significant ontogenetic shifts in food resource utilization occur from naupliar to adult stages. Field grazing rate studies were conducted on an intertidal mudflat over different portions of a tidal cycle using several harpacticoid species (Scottolana canadensis, Microarthridion littorale, Paronychocamptus huntsmani). Highest grazing rates for S. canadensis occurred just …

An Experimental Investigation Into Carbon-Dioxide-Induced Organic Deposition., Josh Chia-Hsine Fu Jan 1987

An Experimental Investigation Into Carbon-Dioxide-Induced Organic Deposition., Josh Chia-Hsine Fu

LSU Historical Dissertations and Theses

Wettability change (or a relative permeability effect) has long been considered a mechanism for enhanced oil recovery. Reports show that adsorption of petroleum heavy ends, mainly asphaltenes and resins, onto a rock surface can alter its wettability. Reports also show that high concentrations of CO$\sb2$ will induce the formation of a solid phase in CO$\sb2$/crude mixtures. However, the propensity of a reservoir system for CO$\sb2$-induced hydrocarbon precipitation and how this deposition affects the rock wettability has not been yet investigated. Once variables such as oil composition, pressure, temperature, brine chemistry, and surface mineralogy are adequately defined it becomes possible to …

Physiological Abnormalities Related To Bulimic Behaviors And Physical Symptoms: Toward A Biobehavioral Analysis., Lisa Dee Hinz Jan 1987

Physiological Abnormalities Related To Bulimic Behaviors And Physical Symptoms: Toward A Biobehavioral Analysis., Lisa Dee Hinz

LSU Historical Dissertations and Theses

Bulimia is an eating disorder characterized by secretive binge-eating and abnormal weight-control practices such as self-induced vomiting, and laxative abuse. To date, investigations of physiological abnormalities accompanying bulimia are recent, few in number, and descriptive in nature. Commonly reported physiological abnormalities have included: increased serum bicarbonate, usually in combination with decreased serum chloride; decreased serum potassium; and decreased hematocrit. Two correlations have provided preliminary evidence that bulimic behaviors are associated with physiological abnormalities. The present investigation attempted to describe more fully the relationships among bulimic behaviors, physiological abnormalities, and physical symptoms. Three separate models, representing different physiological systems: (1) potassium; …
