Establishment Of Laboratory Methods To Assess The Application Of Blood Transfusions In Reptiles, Anke Cordula Stoehr

LSU Master's Theses

A broad knowledge base on veterinary transfusion medicine has been developed in common mammalian species, but little is known in reptiles. The goals of this thesis were to establish laboratory methods to assess the application of blood transfusions in reptiles. Morphological and physiological differences in reptiles, including their erythrocytes, hamper direct adaption of mammalian laboratory methods.

Quantification of percentage hemolysis is a crucial tool for quality assessment of stored red blood cell products. We evaluated measurement of the required analytes for this calculation (supernatant and total hemoglobin) with different methods in blood from American alligators and found that the use …

Water, Waste, And Race: Designing For Change On The Shelby County Landfill, Elizabeth Peterson

LSU Master's Theses

Historically, landfills have been viewed through an environmental lens as sites for technical remediation, employing scientific or engineering strategies for testing, mitigation and capping. They are more rarely viewed as cultural landscapes, places with histories of habitation and use, or as potential sites for design. This thesis investigation examines the Shelby County Landfill in Memphis, Tennessee from a cultural landscape perspective, opening up a dialog and opportunity to think about this site and other waste sites in a more layered and culturally rich way.

This research contributes to discussions within the field of landscape architecture that present waste landscapes as …

The Effects Watermelon Juice On Post Prandial Vascular Endothelial Function And Blood Flow During Hyperglycemia, Cullen M. Vincellette

LSU Master's Theses

Impaired endothelial function and microvascular dysfunction are frequently observed in individuals with cardiovascular risk factors such as obesity, insulin resistance, and type 2 diabetes. Reduced nitric oxide (NO) bioavailability is considered to be central to the development of these risk factors. NO can be generated via enzymatic reaction via NO synthase which requires the amino acid arginine. Evidence suggests that the amino acid citrulline is more effective at increasing circulating arginine levels than arginine supplementation alone. The purpose of this pilot study is to determine the potential for citrulline-rich watermelon juice (WMJ) to attenuate the reduction in postprandial endothelial function …

Water Lily (Nymphaea Thermarum) Genome Reveals Variable Genomic Signatures Of Ancient Vascular Cambium Losses, Rebecca A. Povilus, Jeffrey M. Dacosta, Christopher Grassa, Prasad R.V. Satyaki, Morgan Moeglein, Johan Jaenisch, Zhenxiang Xi, Sarah Mathews, Mary Gehring, Charles C. Davis, William E. Friedman

Faculty Publications

© 2020 National Academy of Sciences. All rights reserved. For more than 225 million y, all seed plants were woody trees, shrubs, or vines. Shortly after the origin of angiosperms ∼140 million y ago (MYA), the Nymphaeales (water lilies) became one of the first lineages to deviate from their ancestral, woody habit by losing the vascular cambium, the meristematic population of cells that produces secondary xylem (wood) and phloem. Many of the genes and gene families that regulate differentiation of secondary tissues also regulate the differentiation of primary xylem and phloem, which are produced by apical meristems and retained in …

Virtual Touch: Embodied Experiences Of (Dis)Embodied Intimacy In Mediatized Performance, Naomi Petrea Bennett

LSU Doctoral Dissertations

In this dissertation, I explore a phenomenon I call virtual touch, in which embodied sensations of touch are felt through non-tactile senses. In the digital age, online interactivity has expanded the ways in which individuals experience connection, intimacy, and touch. Digital media, which have traditionally been thought of as disembodied, nevertheless have the ability to elicit intense feelings of touch. Through analysis of digital and virtual installation art, I examine the ways that non-tactile touch remains rooted in the embodied experience. The works I include in this study create a feeling of virtual touch through a co-functioning of the …

Accurate Tracking Of Position And Dose During Vmat Based On Vmat-Ct, Xiaodong Zhao

LSU Doctoral Dissertations

Purpose: Local tomography reconstruction is achievable with EPID images acquired during VMAT and was named as VMAT-CT. However, it did not gain popularity due to multiple limitations and technical challenges. The goal of this study was to extend VMAT-CT concept, generate complete 3D or 4D CT images and dose, track and adapt VMAT plan based on updated images and dose.

Methods: We considered collimator angle and removed blurred areas in EPID images for VMAT-CT reconstruction to reduce artifacts and improve image quality. VMAT-CT+ images were generated by fusing VMAT-CT and planning CT using rigid or deformable registration. For 4D SBRT …

On Characterizing Quantum Processes And Detectors, Kevin Valson Jacob

LSU Doctoral Dissertations

In 2009, physicists at the National Institute of Standards and Technology in Colorado, Boulder developed what could arguable be called the first rudimentary quantum computer [1]. The past decade has seen unprecedented improvements in quantum information science culminating in the demonstration of quantum supremacy --- that quantum computers can solve problems that are impractical to be solved on the best supercomputers [2]. This remarkable progress necessitates the development of techniques to characterize the quantum devices that are being developed. In my thesis, I will focus on such devices that manipulate and detect light.

In Chapter 1, I will introduce the …

Analyzing Climate Risk To Maritime Cypress Swamps And Pine Savannas Of The Gulf Of Mexico Coastal Plain, Clay Stephens Tucker

LSU Doctoral Dissertations

As sea levels rise, coastal trees are increasingly stressed by saltwater inundation, and stressed trees are ideal for studying changes in the environment through time. Dendrochronology has been used for more than a century to explain changes in past environments using tree rings. Using ring widths and stable isotopes from coastal trees, the effects of tropical cyclones and freshwater moisture availability are shown in regard to tree growth and ultimately are discussed in terms of change to the environment as a whole. Changes in tree growth as they relate to various climate parameters are measured using superposed epoch analysis, moving-window …

Why Do You Take That Route?, Alimire Nabijiang

LSU Master's Theses

We conducted this study to investigate causal factors which affects the route-choice behavior of drivers. Due to the insufficiency of measured variables and the lack of high-fidelity properties obtained by conventional data, we carried out Stated Choice Experiment (SCE) using Immersive Virtual Environments (IVE) tool to collect data. IVE tool can provide realistic virtual experiences to participants, and give advantage of flexible environment for exploring causal factors of drivers’ decision on route choice. Based on reviewing literatures, we believe that there is limited studies that has tried to comprehend the route choice behavior of drivers using causal inference. The study …

Evaluating The Effectiveness Of Continuing Education At Emergency Medical Services, Tasmia Mustaquim

LSU Master's Theses

Emergency Medical Services (EMS) require staff to recertify periodically, which involves a significant amount of continuing education. Great effort is given to designing and delivering a continuing education program, but it is also important to know if the training had all of the intended impacts. Nationally, there is no evidence-based system in place for training evaluation at EMS. This research proposes a framework being used at East Baton Rouge Parish Emergency Medical Services (EBRP-EMS) to evaluate a course, generate reports to indicate the performance of staff, and identify areas of improvement.

The Kirkpatrick Model, which is a 4-level evaluation, is …

Automatic Features Extraction From Time Series Of Passive Microwave Images For Snowmelt Detection Using Deep-Learning – A Bidirectional Long-Short Term Memory Autoencoder (Bi-Lstm-Ae) Approach., Bienvenu Sedin Massamba

LSU Master's Theses

The Antarctic surface snowmelt is prone to the polar climate and is common in its coastal regions. With about 90 percent of the planet's glaciers, if all of the Antarctica glaciers melted, sea levels will rise about 58 meters around the planet. The development of an effective automated ice-sheet snowmelt monitoring system is therefore crucial.

Microwave remote sensing instruments, on the one hand, are very sensitive to snowmelt and can see day and night through clouds, allowing us to distinguish melting from dry snow and to better understand when, where, and for how long melting has taken place. On the …

Night Of The Witch: Alternative Spirituality, Identity And Media, Andreana Tarleton

LSU Master's Theses

This thesis works to understand the relationships witches and conjurors have with the film and television depictions of them. Employing the method of film critique, I argue that the witch stands as a cultural symbol in the US of women and femmes with power, and that their stories serve as lessons to these populations about what it means to be an acceptable woman or femme, while simultaneously creating and perpetuating stereotypes of magic practitioners. Then, using the combination of hashtag ethnography, in-person and video interviewing and internet surveys, I argue that #witchblr and #witchesofcolor, as well as the space of …

Feeding Ecology Of Red Snapper (Lutjanus Campechanus) And Vermilion Snapper (Rhomboplites Aurorubens) Coexisting At The Louisiana Shelf-Edge Banks, Katherine M. Ellis

LSU Master's Theses

Niche partitioning, the process by which competing species use different subsets of the available resources, is commonly used to explain the coexistence of closely related species. In the northwest Gulf of Mexico on the shelf-edge banks, red snapper (Lutjanus campechanus) and vermilion snapper (Rhomboplites aurorubens) are two coexisting closely related species. Yet, little is known about how these species partition resources. In this study, niche partitioning of red snapper and vermilion snapper was investigated using gut contents and stable isotopes. While dietary niche partitioning was apparent, the species relied upon similar prey and displayed isotopic niche overlap, …

The Voice Of Honor: Centering An Indigenous Ethic Of Protocol In U.S. Rhetorical Studies, Dakota Sandras

LSU Master's Theses

This project takes seriously the pressing rhetorical questions facing the field of communication studies which illuminate opportunity for radical disciplinary transformation and demand action beyond heightened racial and cultural awareness. In response, I seek to demonstrate that centering Indigenous epistemologies might inform and advance decolonial strategies for change. More specifically, I examine the theory and practice of First Nations customs of protocol and develop what I deem an ethic of protocol consisting of honor, humility, and action. After observing how these core tenets function synergistically in the protocol of elders, rites of passage, and entering another’s land, I argue that …

Give Us Back Our River's Edge: An Analysis Of Man Made Flood Controls Along The Mississippi River, Taylor Jacobsen

LSU Master's Theses

Settlement and engagement along a river’s edge can be seen throughout human history. The direct proximity to a water’s edge has both physical and mental benefits, as well as economic value. However, throughout the last century, cities and their citizens along the Mississippi River have become disconnected from their water’s edge; due to man-made interventions for increased flood control and advancements in the maritime industry. These interventions appeared to be prudent at the time and contributed to many cities' economies to growth, poor planning and placement of these interventions created barriers between citizens and their water’s edge. This thesis analyzes …

Physical And Biological Factors Controlling The Fate Of Nitrate In A Louisiana Coastal Deltaic Floodplain, Alexandra Christensen

LSU Doctoral Dissertations

The Mississippi River Delta is threatened by a growing pressure to support large human populations in the United States both with food production, navigation systems, and urban development in the Mississippi River Basin. Nitrate-nitrogen load in the Mississippi River, up to 100 Tg N yr^-1 from agricultural and urban runoff, leads to phytoplankton blooms and hypoxia across the Louisiana continental shelf, creating dead zones of low dissolved oxygen threatening a significant commercial fishery. Along the coast and river corridors, floodplain ecosystems have the capacity to retain and remove nitrate. This dissertation explores the role of productive, actively growing coastal …

Family Matters. Or Does It? Family Involvement In American Education, Isaiah Fink Avraham Cohen

LSU Doctoral Dissertations

“Family Matters. Or Does It?” uses select data and waves from the 1996-2016 Parents and Family Involvement in Education Surveys to investigate the following research questions in its efforts to probe the influence of familial involvement: (1) Does child behavior influence family involvement; (2) has the effect of family involvement on academic performance persisted over the past two decades; (3) does school selection influence family involvement; and (4) are homeschooling families monolithic in their involvement? Results indicate that behavior has unique associations with involvement, with no support being found for the reactive involvement hypothesis. Family involvement has a generally positive …

Understanding The Impact Of Psychological Empowerment, Workplace Motivation, And Social Capital On The Job Performance Of Farmers In Honduras: A Mixed Methods Study, Susan Lale Karimiha

LSU Doctoral Dissertations

A farmer’s job performance is critical to the production of raw materials such as food, fiber, and fuel and is therefore an important concern for individuals, businesses, and economies across the world. The literature on improving farmers’ job performance has focused more on introducing new technologies, and less on the psychosocial factors that improve job performance. The primary purpose of this study was to examine the impact of psychological empowerment, workplace motivation, and social capital on farmers’ job performance in Honduras.

A mixed methods approach was used to collect and analyze both quantitative and qualitative data. For quantitative data, a …

The Differences Between Political Islam And The Hizmet Movement In Turkey, Fevzi Sarac

LSU Doctoral Dissertations

This study analyzes the attitudes of two influential social movements in Turkey: the Hizmet movement and political Islam. Historical overview demonstrates that there are continuous and deep attitudinal differences between the movements. I aimed to see the effects of the different attitudes. First, I look how affiliation to a specific movement shape their solution-orientation. Qualitative and quantitative analysis in this research shows that the Hizmet movement follow culture-based solutions while political Islam follows institution-based solutions. Second, I delve into the relationship between affiliation and social capital. The outcomes imply that the Hizmet movement produces bridging social capital whereas political Islam …

An Atmospheric And Spatiotemporal Examination Of Lightning-Initiated Terrestrial Gamma-Ray Flashes Detected By The Fermi Satellite And Tetra Ii, Deirdre Colleen Smith

LSU Doctoral Dissertations

Terrestrial Gamma-ray Flashes (TGFs) are sub-millisecond bursts of the highest naturally occurring light-energy found within Earth’s atmosphere. TGFs are associated with the electric fields produced in thunderstorms and are geolocated by coincident sferics from lightning strokes. Though billions of lightning strokes occur globally each year, fewer than 1,000 TGFs are detected via satellite and ground-based sensors and only a small fraction are geolocated via sferics.

To date, few studies have focused on individual thunderstorms and climates that produce TGFs. This dissertation examines TGFs from two differing data samples: 1) NASA's Fermi Gamma-Ray Burst Monitor (2013-2018) and 2) The TGF and …

Gomcl: A T Gomcl: A Toolkit T Oolkit To Cluster O Cluster, Evaluate, And Extr Aluate, And Extract Non-R Act Non-Redundant Edundant Associations Of Gene Ontology-Based Functions, Guannan Wang, Dong-Ha Oh, Maheshi Dassanayake

Faculty Publications

Background Functional enrichment of genes and pathways based on Gene Ontology (GO) has been widely used to describe the results of various -omics analyses. GO terms statistically overrepresented within a set of a large number of genes are typically used to describe the main functional attributes of the gene set. However, these lists of overrepresented GO terms are often too large and contains redundant overlapping GO terms hindering informative functional interpretations. Results We developed GOMCL to reduce redundancy and summarize lists of GO terms effectively and informatively. This lightweight python toolkit efficiently identifies clusters within a list of GO terms …

Faculty Publications

We present the fourth in a series of catalogs of gamma-ray bursts (GRBs) observed with Fermi's Gamma-ray Burst Monitor (Fermi-GBM). It extends the six year catalog by four more years, now covering the 10 year time period from trigger enabling on 2008 July 12 to 2018 July 11. During this time period GBM triggered almost twice a day on transient events, 2356 of which we identified as cosmic GRBs. Additional trigger events were due to solar flare events, magnetar burst activities, and terrestrial gamma-ray flashes. The intention of the GBM GRB catalog series is to provide updated information to the …

The Impact Of Mindfulness Training On Post-Event Processing In Social Anxiety: A Multi-Method Investigation, Elizabeth Mara Lewis

LSU Master's Theses

Post-event processing (PEP) is theorized to maintain pathological social anxiety. However, little is known about the impact of interventions that may interfere with this maintenance factor. The current study examined the impact of mindfulness training on PEP and state anxiety among socially anxious individuals. Participants were 81 persons (74.07% female, 61.72% non-Hispanic White, M_age = 21.83) with clinically elevated social anxiety who attended one appointment in the laboratory during which they were randomized to receive a brief mindfulness-based training (n = 41) or no training (i.e., thinking as usual control group; n = 40). After the training period, …

Simulating Southern Rust Damage In Corn Through Defoliation, Michael Keith Shannon

LSU Master's Theses

The importance of leaf area to corn for grain production beginning at silking is well documented. However, being able to predict yield loss due to defoliators such as foliar plant diseases and insects that progressively increase in defoliation over time has been difficult to quantify. To address this issue, a leaf removal study was conducted at the Dean Lee Research and Extension Center located near Alexandria, Louisiana in 2017 and 2018. Two hybrids, differing in relative maturity were evaluated in this study. An early maturing hybrid (108 days in 2017 and 107 days in 2018) and a later maturing hybrid …
