Distributional Analysis For Discontinuous Fields, R. Estrada, R. P. Kanwal Feb 1985

Distributional Analysis For Discontinuous Fields, R. Estrada, R. P. Kanwal

Faculty Publications

The jump conditions that hold across singular surfaces for the fields having step function discontinuities do not, in general, apply if these surfaces themselves carry concentrated fields. In this note, the general situation when the surfaces of discontinuity carry multilayers and deform as they propagate is discussed. Formulas are presented for the first and second derivatives for these multilayers. © 1985.

Anatomy Of The Herpes Simplex Virus 1 Strain F Glycoprotein B Gene: Primary Sequence And Predicted Protein Structure Of The Wild Type And Of Monoclonal Antibody-Resistant Mutants, P. E. Pellett, K. G. Kousoulas, L. Pereira, B. Roizman Jan 1985

Anatomy Of The Herpes Simplex Virus 1 Strain F Glycoprotein B Gene: Primary Sequence And Predicted Protein Structure Of The Wild Type And Of Monoclonal Antibody-Resistant Mutants, P. E. Pellett, K. G. Kousoulas, L. Pereira, B. Roizman

Faculty Publications

In this paper we report the nucleotide sequence and predicted amino acid sequence of glycoprotein B of herpes simplex virus 1 strain F and the amino acid substitution in the domains of the glycoprotein B gene of three mutants selected for resistance to monoclonal antibody H126-5 or H233 but not to both. Analyses of the amino acid sequence with respect to hydropathicity and secondary structure yielded a two-dimensional model of the protein. The model predicts an N-terminal, 29-amino-acid cleavable signal sequence, a 696-amino-acid hydrophilic surface domain containing six potential sites for N-linked glycosylation, a 69-amino-acid hydrophobic domain containing three segments …

Comparison Of Drug Effects On Fixed‐Ratio Performance And Chain Performance Maintained Under A Second‐Order Fixed‐Ratio Schedule, Peter J. Winsauer, Donald M. Thompson, Joseph M. Moerschbaecher

Faculty Publications

In one component of a multiple schedule, pigeons were required to complete the same four‐response chain each session by responding sequentially on three identically lighted keys in the presence of four successively presented colors (chain performance). Food presentation occurred after five completions of the chain (i.e., after 20 correct responses). Errors, such as responding on the center or right key when the left was designated correct, produced a brief timeout but did not reset the chain. In the other component, responding on a single key (lighted white) was maintained by food presentation under a fixed‐ratio 20 schedule. In general, phencyclidine …

Loan And Deposit Rate Setting, Risk Aversion, Uncertainty And The Theory Of Depository Financial Intermediaries., Emilio Ramon Zarruk Jan 1985

Loan And Deposit Rate Setting, Risk Aversion, Uncertainty And The Theory Of Depository Financial Intermediaries., Emilio Ramon Zarruk

LSU Historical Dissertations and Theses

This dissertation examines the effects of loan and deposit quantity uncertainty and risk aversion on: (1) the spread between the risk averse loan and deposit rates, and (2) the behavior of the intermediary in the Federal funds market. The intermediary's major function is to provide transaction and liquidity services to its customers. Theoretical results indicate that quantity uncertainty from either loans or deposits reduces the spread to a level below that of a profit maximizing intermediary. The pure effects of quantity uncertainty on the intermediary's spread are consistent and mutually reinforcing regardless of whether uncertainty comes from loans or deposits. …

Poetry In Process: Elizabeth Barrett Browning And The Sonnets Notebook., Phillip David Sharp

LSU Historical Dissertations and Theses

To date, the examination of Elizabeth Barrett Brownings' composition and publication history has been hampered by the inaccessibility of the manuscripts and corrected proofs that were sold at public auction following the death of the Brownings' son in 1913. This examination of the "Sonnets" manuscript notebook at the Armstrong Browning Library at Baylor University, then, sheds new light on Elizabeth Barrett Browning's literary interests and activities in the early 1840's as well as on her methods of composition and revision. Each of the twenty-three poems and fragments in the "Sonnets" notebook was written between 1842-1844, years which mark a turning …

Characterization Of The Modified Phagocytic Vacuole Occupied By Intracellular Toxoplasma Gondii (Macrophage, Protozoa)., L. David Sibley Jan 1985

Characterization Of The Modified Phagocytic Vacuole Occupied By Intracellular Toxoplasma Gondii (Macrophage, Protozoa)., L. David Sibley

LSU Historical Dissertations and Theses

Toxoplasma gondii is a protozoan parasite which resides in modified endocytic compartments of host cells. Extensive intracellular replication and host cell lysis leads to acute toxoplasmosis which is eventually limited by the host immune response to a chronic state of infection. The features of this unique intracellular compartment, which enables Toxoplasma to survive in macrophages, are reported here. Although Toxoplasma survives in normal macrophages, activated macrophages from immune animals rapidly killed Toxoplasma by production of oxygen radicals and intermediates generated during parasite invasion. In addition, activated macrophages inhibited Toxoplasma growth by an oxygen-independent mechanism. Qualitative and quantitative features of oxygen …

Aqueous Phase Oxidation Of Organics (Wet-Air, Vapor-Liquid Equilibrium, Synergism, Free Radical, Xylene, Phenol)., Richard Scott Willms

LSU Historical Dissertations and Theses

Fundamental disappearance kinetics parameters have been obtained for four compounds individually subjected to aqueous phase oxidation. These four compounds are m-xylene, phenol, tetrachloroethylene, and malathion. Concentration histories were obtained using a one liter "sampled-batch" reactor. Reaction conditions ranged from 114-290 (DEGREES)C and 1000-2500 psi air. A kinetics model incorporating vapor-liquid equilibrium effects was developed and used to determine reaction rate constants. The reactions were found to be first order in organic and 1/2 order in oxygen. Induction periods were observed for m-xylene and phenol. The durations of these periods were found to be inversely proportional to oxygen concentration. Activation energies …

Metal Ion, Protein, Phytic Acid Interactions., Elaine Thompson Champagne Jan 1985

Metal Ion, Protein, Phytic Acid Interactions., Elaine Thompson Champagne

LSU Historical Dissertations and Theses

Insight into the mineral, protein, phytate relationships in rice bran was gained by examining the solubility behavior of these components. Solubility profiles of the phosphorus and nitrogen components as a function of pH did not correspond, except in the pH 1.0-2.0 range. This is evidence that association between protein and phytate only occurred in this low pH range. Potassium, magnesium, and calcium solubilities as a function of pH corresponded to those of the phytic acid salts of these minerals. Soluble magnesium and potassium phytates were isolated on Sephadex G-25-50 and identified by ICP, confirming their presence in rice bran. The …

The Population Ecology And Nutrient Transport Of Gulf Menhaden In Fourleague Bay, Louisiana (Mortality, Growth, Feeding, Production, Migration)., Linda Ann Deegan

LSU Historical Dissertations and Theses

An ecological study of the young-of-the-year of three year-classes of gulf menhaden (Brevoortia patronus) was conducted from July 1981 to December 1983 in Fourleague Bay, Louisiana. This study documented gulf menhaden population ecology and the importance of gulf menhaden in the nutrient and energy balance of estuaries. Young-of-the-year gulf menhaden immigrated in winter and moved to tidal creeks and ponds, where they remained until midsummer. They then moved into open bays, where they remained until the fall. This migration pattern coincides with sequentially available, but spatially separate, productivity peaks in marsh and open bays. In the fall, they emigrated to …

Evaluation Of Romanomermis Culicivorax As A Biocontrol Agent Of Larval Mosquitoes In Louisiana Ricelands (Mermithidae, Nematode, Psorophora Columbiae, Parasitism)., Todd Warner Walker Jan 1985

Evaluation Of Romanomermis Culicivorax As A Biocontrol Agent Of Larval Mosquitoes In Louisiana Ricelands (Mermithidae, Nematode, Psorophora Columbiae, Parasitism)., Todd Warner Walker

LSU Historical Dissertations and Theses

Bionomic data were collected to evaluate Romanomermis culicivorax as a biocontrol agent of larval mosquitoes in Louisiana ricelands. In laboratory studies, the ability of R. culicivorax preparasites to infect Psorophora columbiae larvae substantially decreased after hosts were approximately 28 hr old. Parasitism at typical Louisiana rice field temperatures of 26, 29, and 32 (+OR-) 0.5(DEGREES)C showed a significant linear decrease (P < 0.01) as the percentage of older larval instars increased at the times of exposure. These data emphasized the need for a synchronous field application of preparasites to challenge the rapidly developing early instars of Ps. columbiae. Based on those data, applications of postparasites to potential mosquito breeding habitats offer greater flexibility in larval mosquito control programs. A floating bioassay container, constructed of plastic pipe, 50 mesh screening, and 8 oz (0.24 liter) sample bottles, was developed to evaluate R. culicivorax postparasites in irrigated agricultural land. Applications of postparasites applied at dosage rates of 0.025 and 0.05 g/m('2) resulted in the establishment, recycling, and overwintering of R. culicivorax in a riceland habitat in southern Louisiana. Infection rates ranged from 0 to 54.1% during the 22 month study. There was no significant differences (P > 0.05) between dosage rates among the plots and parasitism of Ps. columbiae larvae held in the bioassay containers. Depth of oviposition by R. culicivorax was determined by using soil cores previously inoculated with postparasites. Romanomermis culicivorax was found to …

Essential Reflections Versus Minimal Embeddings, Anthony W. Hager, James J. Madden Jan 1985

Essential Reflections Versus Minimal Embeddings, Anthony W. Hager, James J. Madden

Faculty Publications

This note addresses the following question. In a category C, with a full subcategory X which is reflective with each reflection morphism an embedding, and a C-object A: when does each X-object containing A contain the X-reflection of A? We prove, under mild hypotheses on C, the equivalence of (1) The reflection morphism for A is an essential embedding, (2) Any 'minimal' embedding of A in an X-object is the X-reflection of A, (3) 'Always' is the answer to the question above, (4) The reflection functor C → X carries embeddings of A to embeddings. We note that these conditions …

Environmental And Genetic Sources Of Variation For Seminal Quality In Mature Holstein Bulls, J. E. Chandler, R. W. Adkinson, G. M. Hay, R. L. Crain

Faculty Publications

Various environmental and genetic factors that influence seminal quality were evaluated for 149 Holstein bulls used extensively in nine artificial insemination organizations (studs). These bulls were sons of 16 sires. Seminal quality was measured by percent progressive motility immediately postthaw and after incubation at 3 h, 37°C, percent intact acrosomal membrane after incubation at 3 h 37°C, and percent primary and secondary abnormalities. Semen was thawed at 37 and 24°C. Spermatozoal concentration was counted with a hemocytometer. Bull age and season of collection were determined. Interaction of stud × thaw existed for both motility assessments and intact acrosomes, but 37°C …

Chromatofocusing In The Purification And Separation Of Apo- And Holo-(Vitamin D-Binding Protein), M. J. Keenan, R. P. Holmes Jan 1985

Chromatofocusing In The Purification And Separation Of Apo- And Holo-(Vitamin D-Binding Protein), M. J. Keenan, R. P. Holmes

Faculty Publications

Chromatofocusing was used to purify the vitamin D-binding protein (DBP) from pig plasma in a procedure that consisted of an initial DEAE-cellulose chromatography followed by DEAE-Sephadex chromatography, with final purification by chromatofocusing. The protein was purified 184-fold over its concentration in plasma. When the plasma was labelled with a tracer concentration of [3H]calcidiol, it was apparent that holo- and apo-DBP did not co-chromatograph on chromatofocusing. The separation of these two forms of DBP on chromatofocusing was verified by using purified apo-DBP mixed with either a tracer or a saturating concentration of calcidiol. This separation was consistent with differences observed in …

Raman Microprobe Determination Of Local Crystal Orientation In Laser Annealed Silicon, J. B. Hopkins, L. A. Farrow, G. J. Fisanick Dec 1984

Raman Microprobe Determination Of Local Crystal Orientation In Laser Annealed Silicon, J. B. Hopkins, L. A. Farrow, G. J. Fisanick

Faculty Publications

In this letter we discuss the application of polarization selective Raman microprobe spectroscopy to the detailed, nondestructive analysis of the local crystal orientation of a polycrystalline silicon sample grown over SiO 2 pads and laser annealed. Intensity measurements taken as a function of input polarization angle are fit to an expression derived from the Raman scattering selection rules to calculate the angles by which the crystal structure is twisted within the original substrate plane, as well as the degree of tipping of the crystal plane away from the plane of the Si substrate.
