Sensory Characteristics Of Salt Substitute Containing L-Arginine, Pamarin Waimaleongora-Ek

LSU Master's Theses

Dietary salt restriction is a common approach recommended by physicians in the treatment and prevention of hypertension. Salt substitute is a potential alternative. The most popular salt substitute is KCl, having similar physical properties to NaCl. Because of the higher molecular weight of cations (K+), KCl imparts undesired bitterness and metallic aftertaste. L-arginine has been found to have the bitterness-suppression property. Therefore, it may be used in the mixture of salt substitutes. In the first study, NaCl and four salt substitute solutions consisting of KCl, NaCl, and L-arginine, were developed at 0.5%, 1%, and 1.5% w/v. A discriminative test was …

Retrotransposon Mediated Genomic Fluidity In The Human And Chimpanzee Lineages, Kyudong Han

LSU Doctoral Dissertations

LINE-1s (Long interspersed elements or L1s) and Alus are highly successful non-long terminal repeat retrotransposons with copy numbers of ~520,000 and >1 million within the human genome, respectively. They are associated with human genetic variation and genomic rearrangement. Although they are abundant throughout primate genomes, their propagation strategy remains poorly understood. The recently released human and chimpanzee draft genome sequences provide the opportunity to compare the human genome with the chimpanzee genome. Thus, we were able to assess how these elements expanded in primate genomes and how they create genomic instability during their integration into the host genome as well …

Effect Of Vaccination Of Goats With H-Gal-Gp And H11 Antigens From Intestinal Membrane Cells Of Haemonchus Contortus, Donya Dupree Olcott

LSU Master's Theses

Extracts of adult Haemonchus contortus were purified and used as a vaccine against the blood feeding parasite in goats as previously studied in sheep. The proteins used were H11 and H-gal-GP, hidden gut antigens from the microvillar membrane of the gut of the worm and combined with Quil A as adjuvant, then administered to a group of goats kept on concrete then artificially infected with H. contortus. The control group received Quil A injections and also infected. This study was performed to analyze the effects of the H11/H-gal-GP vaccine when given to goats as compared to sheep. The trial showed …

Verb Aquisition In Students Of English As A Second Language: Language Learning Background And Attitudes, Erin Kyles Rogers

LSU Master's Theses

In order to determine how learner background and learner attitudes affected English as a Second Language students’ verb production, eleven ESL learners participated in both oral and written tasks. They were given written surveys to determine what was emphasized more in learning English in their home countries: speaking or writing. Another survey was administered to determine which of these activities that they liked best. Next, the subjects watched a movie clip, wrote about it, and then spoke about it. Their written and spoken total amount of verbs produced and total amount of verbs used correctly were compared and analyzed to …

Animation In Artificial Grammar Learning: Can Animation Facilitate Learning?, Bill Sallas

LSU Master's Theses

Domangue, Mathews, Sun, Roussel, and Guidry (2004) trained participants to generate valid exemplars from an artificial grammar using either memory-based or model-based processing. Their results showed that learning by memory-based processing resulted in fast but inaccurate performance, while model-based learning resulted in slow but accurate performance. Attempts to integrate both types of training did not result in fast and accurate string generation. Fast and accurate performance was achieved by Sun and Mathews (2004) using a computer animated display to train participants. The current study used a 2x2x2 factorial design to determine why participants who view an animated display of a …

The Antikythera Youth In Its Context, Elisabeth Myers

LSU Master's Theses

The bronze statue known as the Antikythera Youth was discovered in numerous fragments by sponge divers in 1900 with the remains of an ancient shipwreck near the small island of Antikythera, south of the Peloponnesus of Greece. The divers, together with the Greek government, recovered the statue and the rest of the ship’s cargo. The statue was then taken to the National Archaeological Museum, where it was assembled and restored. In the 1950s, the statue underwent a second restoration. This thesis examines the condition of the statue after the restorations and the technique by which it was made. It also …

Mass Media Usage During A Natural Disaster: Lsu College Students And Hurricane Katrina, Pavica Juric

LSU Master's Theses

A survey with 293 American and 68 international LSU students and two focus groups with American students and one with international students were conducted between November 2005 and February 2006 to determine the difference in media use between American and international LSU students in the aftermath of Hurricane Katrina: What were students’ main sources of information after the storm? What were their sources when electricity was out? Which source of information helped students feel less lonely? Which source of information helped students fell less stressful? Finally, which medium did the students believe, when compared to others, did the best job …

Domesticating The Exotic Species: International Biodiversity Law In Canada, Natasha Affolder

All Faculty Publications

While a significant body of international and regional agreements now addresses habitat preservation, wildlife protection, and biological diversity, these advances on the international level often fail to be effectively translated into domestic law. In this article, the author argues that international biodiversity law is being treated in Canada as "exotic". It is peppered into parties' submissions without a principled explanation of its role in Canadian law, receives little consideration from the courts, and must ultimately rely on non-legal means of enforcement. The author examines the jurisprudence dealing with four major biodiversity treaties. She notes that the judicial treatment of these …

Red And Black Tides: Quantitative Analysis Of Water-Leaving Radiance And Perceived Color For Phytoplankton, Colored Dissolved Organic Matter, And Suspended Sediments, Heidi M. Dierssen, Raphael M. Kudela, John P. Ryan, Richard C. Zimmerman

OES Faculty Publications

Using field measurements and quantitative modeling, we demonstrate that red coloration of the sea surface is not associated with any particular group of phytoplankton and is strongly dependent on the physiology of the human visual system. Red or brown surface waters can be produced by high concentrations of most types of algae, colored dissolved organic matter, or suspended sediment. Even though light reflected by red tides commonly peaks in the yellow spectral region (570–580 nm), human color perception requires consideration of the entire spectrum of light relative to receptors within the human eye. The color shift from green to red …

The Convergence Of V-Cycle Multigrid Algorithms For Axisymmetric Laplace And Maxwell Equations, Jay Gopalakrishnan, Joseph E. Pasciak

Mathematics and Statistics Faculty Publications and Presentations

We investigate some simple finite element discretizations for the axisymmetric Laplace equation and the azimuthal component of the axisymmetric Maxwell equations as well as multigrid algorithms for these discretizations. Our analysis is targeted at simple model problems and our main result is that the standard V-cycle with point smoothing converges at a rate independent of the number of unknowns. This is contrary to suggestions in the existing literature that line relaxations and semicoarsening are needed in multigrid algorithms to overcome difficulties caused by the singularities in the axisymmetric Maxwell problems. Our multigrid analysis proceeds by applying the well known regularity …

Evaluation Of The Effectiveness Of A Body Mass Index-For-Age Percentile Health Report In Raising Parent Awareness Of Their Child's Weight Status, Anantha Padmaja Lakkakula

LSU Master's Theses

Overweight in children has become a major health concern. Research suggests that many parents may not be aware of their child’s actual weight status. The objectives of this study were to test the effectiveness of a body mass index (BMI)-for–age percentile report in raising parent awareness of their child’s weight status. Eighteen public elementary schools in southeast Louisiana were pair matched and divided into nine intervention and nine control schools. Children in the intervention and the control schools were divided into two groups 1) healthy weight (BMI ≥ 5th to <85th percentile) and 2) at risk and overweight (BMI ≥ 85th percentile). Forty children were randomly selected from each of the two weight groups from the intervention and the control schools. Parents of children in the intervention group received a BMI-for-age percentile health report along with a short questionnaire. Parents of children in control schools received the questionnaire only. Parents in the intervention group have 4.7 times more accurate perception about their child’s weight compared to the control group (OR: 4.7, 95% of CI: 0.89-24.86, p=0.00 ). After receiving the report, more parents of at risk or overweight children were concerned and only fewer parents of healthy weight children were anxious about their child’ weight. When parents were compared based on their child’s weight regardless whether they got the report, parents of at risk or overweight children were more than five times less likely to perceive the correct weight classification of their child (OR: 1.8, 95% of CI: 0.05-0.62, p=0.00) and less concerned about their child’s weight (OR: 0.98, 95% of CI: 0.32-2.93, p=0.00) when compared to parents of healthy weight children. All parents were willing to help their child follow healthy behaviors regard less of the report and their child’s weight status. A BMI-for-age percentile report appears to be an effective way to increase parent awareness and concern regarding their child’s weight status. With increased awareness, parents may be more likely to encourage their children to achieve a healthy weight.

A New Method To Determine Radiative Properties Of Rough Solid Surfaces, Raghu Nandan Mutukulla

LSU Master's Theses

The radiative properties of the rough surfaces are important both from fundamental and practical standpoint. Thus, there is a need to determine the effect of roughness on radiative properties of materials accurately, as these properties effect the performance of electronic devices, communication devices, optical sensors, and furnaces, amongst others. The effects of roughness are assessed by measuring the reflection coefficients from the carbon rod surfaces and steel 1086 samples over the range of angles 25 to 75 in the visible range and near infrared region. Different levels of roughness are induced on the surfaces by utilizing different grid size sand-paper …

Calibration Of Flexural Design Of Concrete Members Reinforced With Frp Bars, Sujata Nandkumar Kulkarni

LSU Master's Theses

Fiber Reinforced Polymer (FRP) composites have been increasingly accepted in the construction industry as a promising substitute for steel. Bridge deck deterioration is one of the most common deficiencies in a bridge system. The use of FRP bars as reinforcement for concrete bridge decks provides a potential for increased service life, economic, and environmental benefits. This research presents the development of resistance models for concrete members (beams and slabs) reinforced with FRP bars (FRP-RC), for carrying out reliability analysis. The scope of this model is limited to the flexural behavior only; i.e. the failures are not shear failure and debonding. …

Verification Of Direct Brachytherapy Dosimetry For A Single Seed Implant, Jabari Robinson

LSU Master's Theses

A new technique using direct post-implant dosimetry, which does not depend explicitly on brachytherapy seed orientation or position, was explored for a prostate and a breast case. This technique, proposed by E Sajo and ML Williams (SW), uses trace amounts of positron emitters placed in the seed capsule and uses the positron emission tomography image in conjunction with a computed tomography image (PET-CT) to compute the therapeutic dose distribution in the patient. The SW technique could reduce errors in the post-implant dose computations associated with seed localization, seed shadowing and medium heterogeneity. Dose point kernels were obtained using Monte Carlo …

Investigation Of The Structure In Electrodeposited Nanostructured Co/Cu Alloys, Multilayers, And Cofe/Cu Multilayered Nanowires, Erick Jamal Lawson

LSU Master's Theses

Since the discovery of giant magnetoresistance (GMR) in electrodeposited nanostructured magnetic multilayers and multilayered nanowires, there has been interest throughout the scientific world in the fabrication and characterization of these materials. Magnetic multilayers in the form of thin films can be used as magnetoresistive sensors in the magnetic data storage industry. Arrays of nanowires have the potential for applications in perpendicular ultra-high density data storage and biosensors. Wire-shaped magnetic multilayered nanowires have been shown to exhibit GMR in the so called “current perpendicular-to plane” configuration (CPP-GMR). GMR of multilayers and multilayered nanowires have been investigated in several systems that include …

Effects Of Smoking Cessation And Female Sex Hormones On Food Intake In Postmenopausal Women, Megan Ranae Apperson

LSU Master's Theses

Following smoking cessation, individuals increase their food intake. Women experience greater postcessation hyperphagia than men, and older women may increase their food intake more than younger women. Some research has suggested that postcessation increases in food intake may be macronutrient specific. However, previous investigations of macronutrient specific changes in food intake following smoking cessation have had significant methodological problems. The current study assessed changes in total food intake and macronutrient selection using the Macronutrient Self-Selection Paradigm (MSSP), a direct, laboratory based measure of food intake that is valid and reliable with respect to macronutrient intake. Fifty-five postmenopausal females completed the …

Mapping A Weak Hypercube On An Optical Slab Waveguide, Divya Rengan

LSU Master's Theses

The communication fabric of a parallel processing system is represented as a directed graph. In a weak topology a processor uses at most one incoming edge or one outgoing edge for communication at any given point in time. Currently, the data rate that can be supported on electronic interconnects is reaching its limits. Optical interconnects have been identified as one of the most promising approaches to the growing demands for today's systems. The “medium bandwidth” of an optical waveguide is huge (order of petabits per second for a 1mm2 cross-section optical slab). The challenge lies in utilizing as much of …

Tomotherapy For Post-Mastectomy Radiotherapy (Pmrt): Comparison With Conventional Electron Beam Technique, Michael Sissay Ashenafi

LSU Master's Theses

Purpose: TomoTherapy, capable of delivering intensity-modulated, image-guided radiotherapy with a helical fan-beam, multileaf-collimated beam and detector array mounted on a CT ring, is challenging the treatment techniques commonly used in today's radiotherapy clinic. The present works investigates the potential of using TomoTherapy in lieu of electron beams for treatment of the chest wall in post-mastectomy radiotherapy (PMRT). It is hypothesized that TomoTherapy can plan dose distributions for PMRT patients, that a pre-selected radiation oncologist judges to be equal to or better than that of a conventional plan treated with electron beams. Methods: A patient database of retrospective conventional PMRT treatment …

An Analysis Of The Relationship Between City Typology, Interactivity And Advertising Message Strategies Of American Municipal Web Sites, Jeremy John Starr

LSU Master's Theses

This study became to first to scientifically explore the relationship between city typology and the use of advertising message strategy and interactivity within municipal web sites. The study used Taylor’s six-segment strategy wheel to analyze message strategies and previous scales of interactivity to analyze structural interactivity. Medium-size cities and cities within the South and West geographic regions more likely used sensory strategies within their web sites. Cities with racially diverse populations more likely used sensory strategies within their web sites as well. Large cities and central cities, both with large populations, used the most interactive strategies within their sites compared …

"Reasonably Predictable:" The Reluctance To Embrace Judicial Discretion For Substantial Assistance Procedures, India Geronimo Thusi

Articles by Maurer Faculty

This Comment focuses on the nuances of post-Booker cooperation departures and sentence variances. Section 5K1.1 of the Guidelines governs the provision of cooperation, or substantial assistance, departures. This provision was the primary method for defendants to receive cooperation departures prior to Booker. The section 5K1.1 provision allowed substantial assistance departures where the prosecution actually benefited from the defendant’s cooperation.

First, Part I.A of this Comment will provide an overview of the original goals of the Sentencing Commission and the section 5K1.1 substantial assistance provision. Part I.B of the Comment summarizes United States v. Booker and its impact on cooperation departures. …

Bringing Sense To Incentives: An Examination Of Incentive Payments To Named Plaintiffs In Employment Discrimination Class Actions, Nantiya Ruan

Scholarly Works

Employment discrimination class actions (EDCA) are complex creatures for many reasons. One complexity involves the resolution of EDCAs, which typically includes a provision for an incentive award or "bonus" for named plaintiffs. This Article describes five models under which courts struggle with awarding incentive awards to named plaintiffs in EDCAs. It examines how (under which model) and why (upon what justification) courts award or refuse to award incentive payments. This examination illustrates that courts have failed to differentiate between incentive payments that further Title VII's statutory goal of workplace fairness and other litigation matters, such as securities litigation or consumer …

Classical And Quantum Algorithms For Finding Cycles, Jill Cirasella

Publications and Research

Quantum computing—so weird, so wonderful—inspires much speculation about the line between the possible and the impossible. (Of course, there is still unclarity about how “impossible” intractable problems are and about how “possible” quantum computers are.) This thesis takes a slightly different tack: instead of focusing on how to make the impossible possible, it focuses on how to make the possible easier.

More specifically, this paper discusses quantum algorithms for finding cycles in graphs, a problem for which polynomial-time classical algorithms already exist. It explains and compares the classical and quantum algorithms, and it introduces a few new algorithms and observations. …

An Economic Assessment Of Genetic Information: Leptin Genotyping Of Breeding Cattle, Jay Douglas Mitchell

Agribusiness and Applied Economics

Recent studies show polymorphisms in the leptin gene significantly impact milk production in dairy cattle. If the leptin gene were to have a similar impact on beef cattle, calf weaning weights would be expected to increase from the increased milk production in the cows. Since weaning weight is a key component of profitability in a cow-calf operation, leptin genotyping may prove to have an economic impact in breeding cattle. However, no research has been done to link the economic impact of increased milk production to breeding cattle. Using 595 observations from genotyped cows spanning 11 years (1995-2005), calf weaning weight …
