We report measurements of the mass density, ΩM, and cosmological-constant energy density, ΩΛ of the universe based on the analysis of 42 type Ia supernovae discovered by the Supernova Cosmology Project. The magnitude-redshift data for these supernovae, at redshifts between 0.18 and 0.83, are fitted jointly with a set of supernovae from the Calán/Tololo Supernova Survey, at redshifts below 0.1, to yield values for the cosmological parameters. All supernova peak magnitudes are standardized using a SN Ia light-curve width-luminosity relation. The measurement yields a joint probability distribution of the cosmological parameters that is approximated by the relation 0.8ΩM - 0.6ΩΛ …

The Long Isoform Uncoupling Protein-3 (Ucp3l) In Human Energy Homeostasis, W. K. Chung, A. Luke, R. S. Cooper, C. Rotini, A. Vidal-Puig, M. Rosenbaum, D. Gordon, S. M. Leal, S. Caprio, R. Goldsmith, A. L. Andreu, C. Bruno, S. Dimauro, M. Heo, W. L. Lowe, B. B. Lowell, D. B. Allison, R. L. Leibel

Faculty Publications

The biological role(s) proposed for UCP3 in energy homeostasis have been based primarily upon amino acid sequence homology to UCP1. Spontaneous mutations of UCP3 have been described in humans, but not in rodents. The functional consequences—or lack thereof—of these mutations in humans will be of great importance in elucidating the biology of this protein. The results of two such studies are summarized here. © 1999 Stockton Press. All rights reserved.

Archaeological Investigation Of Unit Two At The Sharp Site (16lv13), Livingston Parish, Louisiana, Laura Cathleen Tanley

LSU Historical Dissertations and Theses

This thesis is an examination of southeastern Louisiana archaeology focusing on Unit Two at the Sharp site (16LV13) on the Lower Amite River. The artifact analysis, and more specifically the pottery analysis, demonstrated a significant early occupation at the site. The analyzed pottery represents cultural components at the Sharp site which span from the Tchula through Coles Creek periods.

Within Unit Two there was an obvious subsistence change evident. The upper strata of the midden contained a great deal of Rangia clam shell, while the earlier cultural occupations below it did not. This change in exploitation of local food sources …

The Life History Of Southern Flounder (Paralichthys Lethostigma) In Louisiana Waters, Andrew James Fischer

LSU Historical Dissertations and Theses

The objectives of this study were to describe the life history patterns of the southern flounder (Paralichthys lethostigma) in Louisiana waters through determination of age, growth, and reproductive biology. A variety of sample sources were included to demonstrate how the southern flounder life cycle is dependent on both the estuary and offshore waters throughout the various stages of its life cycle. Females exhibited greater lengths then males reaching a maximum of 764mm total length and males a maximum of 414mm. Ages were estimated through examination of transverse sections of sagittal otoliths. Annuli were validated to form yearly in the winter …

Dark Phoenix: The Representation Of Black Woman In Je Suis Martiniquais By Mayotte Capecia And Mon Examen De Blanc By Jacqueline Manicom, Sybil Shevron Jackson

LSU Historical Dissertations and Theses

Black women writers in the French West Indies were conspicuously absent from the literary canon during the negritude movement in the 1940's. Mayotte Capecia was one of the few who managed to write during this time. Capecia was criticized severely for her novel Je suis Martiniquais by Frantz Fanon and accused of betraying her race because of the inter-racial love affair between her heroine and a French soldier. Jacqueline Manicom, her literary descendant who wrote Mon Examen de Blanc in 1972, was ostracized from the medical profession for her political beliefs concerning women's rights.

This dissertation examines images and representation …

First Observations Of An R Coronae Borealis Star With The Space Telescope Imaging Spectrograph: Ry Sagittarii Near Maximum Light, Geoffrey C. Clayton, T. R. Ayres, Warrick A. Lawson, John S. Drilling, P. Woitke, Martin Asplund

Faculty Publications

We describe the far-UV (1140-1740 Å) spectrum of the hydrogen-deficient R Coronae Borealis (RCB) star RY Sgr, obtained near maximum light (pulsational phase ≯0.1) by the Space Telescope Imaging Spectrograph (STIS) on Hubble Space Telescope. The far-UV spectrum shows a photospheric continuum rising steeply toward longer wavelengths and two prominent emission features at the shorter wavelengths: C II λ1335 and Cl I λ1351 (the latter is radiatively fluoresced by the 10 times stronger C II multiplet). We also find evidence for CO A-X 4th-positive system absorption band heads and possible weak CO fluorescent emissions pumped by C II λ1335, but …

Diets Of White-Tailed Deer At Avery Island, Louisiana, Nathan D. Rains

LSU Historical Dissertations and Theses

I conducted a food habits study of white-tailed deer (Odocoileus virginianus) at Avery Island, Louisiana, to determine if deer diets differed among seasons. In 1997, I randomly collected 25 seasonal fecal pellet groups in January. April, August and October respectively I also collected reference forage plant samples in conjunction with fecal pellet collections I estimated botanical composition of deer diets based on a microscopic analysis of fecal pellets I compared diets using a chi- squared contingency table to assess significant seasonal variation I also used Kulczynski's similarity index to determine degree of similarity among seasonal diets

I found significant differences …

Hubble Space Telescope Observations Of The Black Hole X-Ray Transient Gro J0422+32 Near Quiescence, R. I. Hynes, C. A. Haswell

Faculty Publications

We present HST/FOS ultraviolet and optical spectroscopy of the black hole X-ray transient GRO J0422+32 shortly before the system reached quiescence. We find that the accretion spectrum from 2500 to 9000 Å can be very well fitted by a self-absorbed synchrotron model, with superposed H I and Mg II emission lines. The explanations that we suggest for this spectrum are either that it is due to active coronal regions above a geometrically thin accretion disc, or that the disc is evaporated into an advective flow.

Iconic Animation Of Construction Simulation, Jonathan Jingsheng Shi, H. Zhang

Faculty Publications

This paper presents a continuous research effort the animation function in the development of the Activity-Based Construction (ABC) modeling and simulation system. ABC animation uses the constructed ABC simulation model as the animation background; and pre-created images of simulation entities move around along individual execution paths on the ABC model. A library of icons consisting of common construction entities has been created in the ABC system. To perform animation function in ABC only involves one simple additional task for the user to select an appropriate icon for a simulation entity.

An Examination Of The Spaced-Retrieval Technique: A Method To Improve Memory In Older Adults With Probable Alzheimer's Disease., Shannon S. Simmons-D'Gerolamo

LSU Historical Dissertations and Theses

In this study, we used the spaced-retrieval technique as a mnemonic device for those persons with cognitive deficits such as probable Alzheimer's Disease. Three main goals of this research were to gain insight into the long-term effectiveness of the spaced-retrieval technique, examine ways to enhance the overall effectiveness of the spaced-retrieval technique, and adapt spaced-retrieval for applied use in real-world settings. Results indicated that participants did not show savings-in-relearning over a two year follow-up span, but did show it over a one year and six month span. Results provided modest evidence of the effects of exposure to the target-item orientation …

Quantitative Modeling And Information System Support For Just -In -Time Partnership., Faisal Badi Al-Khateeb

LSU Historical Dissertations and Theses

Just-in-Time (JIT) supply calls for frequent, small deliveries, which arrive on time, with the quantity and quality required. For JIT to be effective there should be a cooperative relationship between the buyer and the supplier. They should work together to enhance their competitive positions in the market place. This study extends the quantitative models published in the literature to provide more realistic models for JIT operations and evaluates the costs and benefits of JIT partnerships to help in the negotiation process between the partners. We provide a new model for the optimization of the joint total relevant cost of the …

On The Numerical Solution Of The Cylindrical Poisson Equation For Isolated Self -Gravitating Systems., Howard Saul Cohl

LSU Historical Dissertations and Theses

This dissertation addresses the need for an accurate and efficient technique which solves the Poisson equation for arbitrarily complex, isolated, self-gravitating fluid systems. Generally speaking, a potential solver is composed of two distinct pieces: a boundary solver and an interior solver. The boundary solver computes the potential, phi(xB) on a surface which bounds some finite volume of space, V, and contains an isolated mass-density distribution, rho(x). Given rho(x) and phi(xB), the interior solver computes the potential phi(x) everywhere within V. Herein, we describe the development of a numerical technique which efficiently solves Poisson's equation in cylindrical coordinates on massively parallel …

Clarinet Concertos By Post World War Ii Generation Norwegian Composers: Bjorn Kruse, Olav Berg, And Rolf Wallin., Beverly Ann Gibson

LSU Historical Dissertations and Theses

A substantial body of Norwegian clarinet literature exists that is infrequently performed outside of the Scandinavian countries and Europe. A new generation of composers emerged in the 1980s who have made visible their own individual approaches to composition. This monograph focuses on a selection of clarinet concertos composed by Bjorn Kruse (b. 1946), Olav Berg (b. 1949), and Rolf Wallin (b. 1957) which represent the most extensive pieces for clarinet in the respective composers' outputs to date and have been awarded prizes in composition contests. The composers have distinguished themselves as leading figures in the contemporary music scene in Norway, …

The Effect Of *Modeling And Tempo Gradations As Practice Techniques On The Performance Of High School Instrumentalists., Paul Thomas Henley

LSU Historical Dissertations and Theses

The purpose of this study was to examine the effect of modeling conditions and tempo gradations as practice techniques on the performance of high school instrumentalists. Specifically, the independent variables of this study were model versus no model; and steady increase of tempo versus performance speed tempo versus alternating (slower and faster) tempos. Subjects (N = 60) were high school wind instrumentalists from the Midwest and the South. Subjects sight-read an etude, practiced the same etude six times using one of six distinct practice conditions, which were combinations of the two independent variables, and performed a posttest on the same …

Holding Back The Waters: Land Development And The Origins Of Levees On The Mississippi, 1720-1845., Jeffrey Alan Owens

LSU Historical Dissertations and Theses

Man's efforts to control flooding on the Mississippi began about 280 years ago, but the first 130 years has been neglected in scholarly literature. In spite of abundant primary sources, most histories of flood control on the Mississippi revolve around hydraulic engineering and the contributions of state and federal levee bureaucracies---factors which had almost no impact on the creation of the levee system. Engineers did install the first levee at New Orleans and levees on their own plantations in the 1720s, but the extension of the levee line thereafter was almost entirely the work of private land developers supervised at …

Interactions On Minerals And Organic Materials Along The Salinity Gradient In Barataria Basin, Louisiana., Jessica Anne Kastler

LSU Historical Dissertations and Theses

Changes in the associations among mineral and organic materials in estuaries may control the nature and quantity of organic material (OM) preserved in sediment deposits or cycled in the water column. Estuarine sediment-OM attachments were examined using descriptive analyses and experiments to assess their response to salinity changes and the bioavailability of sedimentary OM. Desorption experiments compared the amount of organic carbon extracted from sediment in rinses of different salinity. Uptake experiments monitored changes in carbon and bacteria concentrations to compare the bioavailability of dissolved and sedimentary OM. Clay mineralogy, surface area and elemental analysis of suspended and deposited sediment …

Precursors For Chemical And Photochemical Vapor Deposition Of Copper Metal., Alicia Marie James

LSU Historical Dissertations and Theses

The colorless square-planar cluster [CuN(SiMe3)2] 4, which contains four Cu(I) ions with four bridging amide groups, was studied as a precursor for chemical and photochemical vapor deposition of Cu metal. The cluster phosphoresces in CH2Cl2 solution and in the solid state at room temperature. Its electronic spectrum in CH 2Cl2 consists of two intense bands which are assigned to symmetry-allowed 3d → 4p transitions; the phosphorescence is also likely to be metal-centered. Solid [CuN(SiMe3)2]4 luminesces with approximately the same spectrum as that of the CH2Cl2 solutions. At 77 K, the solid-state luminescence red-shifts slightly. The emission lifetime in glassy Et2O …

Effectiveness Of Web-Based Virtual Learning Environments In Business Education: Focusing On Basic Skills Training For Information Technology., Rami Mahmoud Ahmad

LSU Historical Dissertations and Theses

Calls for transforming the learning industries and revolutionizing business education are being answered by a proliferation of virtual learning environments, capitalizing on ever-growing and universal Internet-related technologies. This dissertation describes research investigating the effectiveness of web-based virtual environments by comparing traditional and information technology enhanced learning environments. A conceptual framework is proposed contrasting the effectiveness of these two environments across two learning models---the objectivist and the constructivist. Although technology may serve as a moderator that enhances the implementation of certain features of a learning model, there is a consensus that the learning model---not the technology---is the primary cause of learning. …

An Analysis And Performer's Guide To The Sonatine For Flute And Piano By Pierre Boulez., Diana M. Tiffany

LSU Historical Dissertations and Theses

In spite of the preeminence of its composer, the Sonatine for Flute and Piano by Pierre Boulez is not a well known work. The piece poses truly formidable technical and aesthetic challenges for players and audiences. The purpose of this study is to present an analysis and some practical suggestions for flutists preparing the piece for performance. This serial-based work is divided into four continuous main stanzas, each demonstrating a different style and varying compositional techniques while using the same row. The repetition of specific pitch-class sets, rhythm motives, and pitch classes within each stanza lends each one aurally identifiable …
