Five-Dimensional Quasispin And The Spectra Of Odd-Parity Yrast Configurations In The Ba Region, K. J. Weeks, J. P. Draayer, K. T. Hecht
Five-Dimensional Quasispin And The Spectra Of Odd-Parity Yrast Configurations In The Ba Region, K. J. Weeks, J. P. Draayer, K. T. Hecht
Faculty Publications
The 5-dimensional quasispin formalism is used to evaluate the (n, T)-dependent factors of the matrix elements of abnormal parity operators of relevance for yrast-band spectroscopy. The formalism allows the leading pseudo-SU(3) representation of the normal (N) parity part of a shell-model configuration to be coupled to low-seniority states of the abnormal (A) parity high-j intruder part of the configuration. To illustrate the importance of the nA, TA dependence of the (A) to (N) space-coupling matrix elements this model is applied to the negative-parity yrast spectra of 127La and 127Ba, using hamiltonian parameters which give a reasonable fit for 126Ba.

A Time Series Model Of The Controller Functions Of The Human Temperature Regulating System., Mohsen Neghabat
A Time Series Model Of The Controller Functions Of The Human Temperature Regulating System., Mohsen Neghabat
LSU Historical Dissertations and Theses
The objective of this study is to develop time series models of the controller mechanisms of the human temperature regulating system. The controller responses are: changes in metabolic heat production, changes in evaporative heat loss and alterations in the surface blood flow. After evaluating the models developed for the controller mechanisms, the models are validated in the context of a complete simulation model of temperature regulation. Additionally, upper and lower limits are set for the controller responses. Because of the nature of the data available for surface blood flow, this controller response is not represented by time series models. Published …
Speciation Studies Of Biologically Active Compounds (Atomic Absorption, Ultrasonic Nebulization, Hplc, Organoleads, Aminoglycosides-Metal Complexes)., Edmund Douglas Boothe
Speciation Studies Of Biologically Active Compounds (Atomic Absorption, Ultrasonic Nebulization, Hplc, Organoleads, Aminoglycosides-Metal Complexes)., Edmund Douglas Boothe
LSU Historical Dissertations and Theses
Part I. Development of a new nebulizer-flame atomizer atomic absorption system designed for metal speciation. A new flame atomic absorption system has been designed and developed. A new, highly efficient ultrasonic nebulizer was used for sample introduction and aerosol generation. Extensive evaluations and modifications of commercially available atomic absorption spray chambers and burner heads were conducted. Observations made during these studies centered on some of the fundamental properties of aerosol transport within the atomic absorption nebulization system. The new flame atomic absorption system consisted of the ultrasonic nebulizer incorporated into a modified spray chamber. The aerodynamic properties of the chamber …
The Effects Of Oral And Oral-Visual Dictation Exercises On A Specific Writing Skill Of Selected College Developmental Students (Remedial, Television, Controlled Composition)., Ronald Maurice Simeral
The Effects Of Oral And Oral-Visual Dictation Exercises On A Specific Writing Skill Of Selected College Developmental Students (Remedial, Television, Controlled Composition)., Ronald Maurice Simeral
LSU Historical Dissertations and Theses
This research was designed to examine the effects of dictation exercises on the scores of developmental students on a test of a specific English writing skill. Additionally, the study examined the differences in these scores based on the preference type scales of the Myers-Briggs Type Indicator (MBTI) in order to test the hypothesis that certain MBTI types that handle the oral language well would learn writing skills faster when exposed to dictation exercises related to those skills. A pre-test and a post-test were administered to three groups of developmental writing students at Nicholls State University. All three groups were taught …

Herman Frasch (German Immigrant Chemist, Standard Oil, Petroleum; Ohio, Louisiana)., William Ralph Sutton
LSU Historical Dissertations and Theses
Herman Frasch (1851-1914) invented the hot-water process for mining sulphur that permitted the exploitation of the rich deposits beneath the coastal plain of the Gulf of Mexico. The Frasch process enabled the United States to become self-sufficient in the production of this important industrial mineral and the major supplier to the world. Frasch's new idea was to inject steam into the underground deposit to melt the sulphur and then pump the liquid to the surface. He patented the process in 1891 and first demonstrated its technical success at Sulphur, Louisiana in 1894. Initially plagued with problems due to the high …
Ordered Models For The Lambda Calculus., Frederick Joseph Sullivan
Ordered Models For The Lambda Calculus., Frederick Joseph Sullivan
LSU Historical Dissertations and Theses
Although the (lamda)-calculus has been studied for over fifty years, the first models for the lambda calculus were constructed by Dana Scott in 1972. Scott's models were constructed using inverse limits of continuous lattices. We investigate this inverse limit construction in the context of up-complete posets with zero. We show that the correspondence between an up-complete poset with zero P and its associated model for the (lamda)-calculus defines a monofunctor between appropriate categories. We calculate the values in the model corresponding to several combinators in the lambda calculus. Finally, we investigate certain submonoids of the monoid of combinators. We show …
Weierstrass Points On Gorenstein Curves., Carl Archer Widland
Weierstrass Points On Gorenstein Curves., Carl Archer Widland
LSU Historical Dissertations and Theses
This thesis generalizes the classical definition of a Weierstrass point to integral projective Gorenstein curves. For X an integral projective Gorenstein curve of arithmetic genus g at least two, pick P(epsilon)X, and call the sheaf of dualizing differentials (omega). For a proper closed subscheme Z of X with support P and ideal sheaf I, define the degree of Z to be dim(,(//C)) O(,P)/I(,P). Call Z 1-special if dim(,(//C))Hom(I,O(,X)) (GREATERTHEQ) 1. In a manner analogous to the classical construction, one defines the wronskian of X to be some element (alpha) of (H('0) (X,(omega)('(CRTIMES) 1/2(g('2)+g)))). One defines the Weierstrass weight W(P) to …
A Study Of The Texture Measurement Definition Problem (Image Analysis)., Ramon Emilio Vasquez-Espinosa
A Study Of The Texture Measurement Definition Problem (Image Analysis)., Ramon Emilio Vasquez-Espinosa
LSU Historical Dissertations and Theses
The problem of texture measurement definition is studied. A theory is presented in order to overcome the problem. This theory includes a conceptual framework for the general measurement definition problem. This framework is based on the concepts of a perceptual transform, a perceptual space, a measurement transform and a similarity transform. Using this conceptual framework and a particular choice for the similarity transform, a set of requirements are defined. These requirements can be used to create a formal method for defining measurements off the GLC matrices. The formal procedure is based on preserving perceptual relationships among textures. To apply this …

Interactive Three Dimensional Computer Graphics Simulation Of The Kinematics Of The Human Thumb (Biomechanics, Functional Anatomy, Skeletal Kinematics)., William Leslie Buford Jr
LSU Historical Dissertations and Theses
This dissertation describes the development of a computer graphical simulation of thumb kinematics as a clinical design tool. The simulation utilizes a realistic data structure of the thumb bones, an optimized model of joint kinematics, and a variety of experimental cadaver measurements. It was developed with a concurrent processing arrangement in which graphical transformations and interactive manipulations are handled on a distributed graphics system, and musculoskeletal dynamics calculations are carried out on a minicomputer. The thumb simulation includes interactive entry of patient related data, simulation of two types of tendon transfer operations, calculation and display of resultant muscle mechanics during …
The Design And Evaluation Of An Integrating Monitoring Device For Ozone Using 10,10'-Dimethyl-9,9'-Biacridylidene., Marion Rene Surgi
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 …

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

On The Order-Theoretical Foundation Of A Theory Of Quasicompactly Generated Spaces Without Separation Axiom, Karl H. Hofmann, Jimmie D. Lawson
Faculty Publications
A Hausdorff space X is said to be compactly generated (a /e-space) if and only if the open subsets V of X are precisely those subsets for which K n V is open in K for all compact subsets of K of X. We interpret this property as a duality property of the lattice 0{ X) of open sets of X, This view point allows the introduction of the concept of being quasicompactly generated for an arbitrary sober space X. The methods involve the duality theory of up-complete semilattices, and certain inverse limit constructions. In the process, we verify that …

A Harnack Estimate For Real Normal Surface Singularities, William A. Adkins
A Harnack Estimate For Real Normal Surface Singularities, William A. Adkins
Faculty Publications
According to Harnack’s theorem the number of topological components of the real part of a nonsingular projective curve X defined over R is at most g(X) + 1, where g(X) is the genus of X. The purpose of the present paper is to present two estimates which can be considered analogs of Harnack’s theorem for normal surface singularities defined over R. © 1984 by Pacific Journal of Mathematics.

Incompressible Planar Surfaces In 3-Manifolds, C. Mc A. Gordon, R. A. Litherland
Faculty Publications
Let M be an orientable 3-manifold and T a torus component of ∂M. We show that the boundary-slopes of incompressible, boundary-incompressible planar surfaces (P,∂P)⊂(M,T) are pairwise within distance 4; in particular, there are at most six such boundary-slopes. A corollary is that, for any knot K in S3, at most six Dehn surgeries on K can yield a reducible 3-manifold. © 1984.
On Minor-Minimally-Connected Matroids, James G. Oxley
On Minor-Minimally-Connected Matroids, James G. Oxley
Faculty Publications
By a well-known result of Tutte, if e is an element of a connected matroid M, then either the deletion or the contraction of e from M is connected. If, for every element of M, exactly one of these minors is connected, then we call M minor-minimally-connected. This paper characterizes such matroids and shows that they must contain a number of two-element circuits or cocircuits. In addition, a new bound is proved on the number of 2-cocircuits in a minimally connected matroid. © 1984.
