Bermudagrass (Cynodon spp. Rich) is a warm-season grass that is widely planted throughout tropical, sub-tropical, and even temperate climates, and it generally requires fewer inputs than most cool-season turfgrasses. In recent years, the area of adaptation for bermudagrass has progressively expanded to cooler climates due to the development of more cold-tolerant cultivars. The expanded area of adaptation as well as the reduced inputs required to maintain healthy turfgrass have made bermudagrass a popular choice in areas of marginal adaptation. In these areas, the greatest threat to bermudagrass health and survivability is winterkill. This management guide seeks to describe winterkill: what …

Substituent Effects On The Photophysical Properties Of A Series Of 8(Meso)-Pyridyl-Bodipys: A Computational Analysis Of The Experimental Data †, Petia Bobadova-Parvanova, Dylan Goliber, Elijuah Hernandez, Daniel Lamaster, Maria Da Graça H. Vicente

Faculty Publications

Recently, a series of 8(meso)-pyridyl-BODIPYs (2-pyridyl, 3-pyridyl, and 4-pyridyl) and their 2,6-substituted derivatives were synthesized and their structure and photophysical properties were studied both experimentally and computationally. One of the main observed trends was that the 2-pyridyl-BODIPYs were consistently less fluorescent than their 3-pyridyl and 4-pyridyl analogs, regardless of the 2,6-substituents. Herein, we extend our previous computational studies and model not only the ground but also the excited states of the entire series of previously synthesized meso-pyridyl-BODIPYs with the aim of explaining the observed differences in the emission quantum yields. To better understand the trends and the effect of 2- …

The Avo-ZNPs with various Avo contents showed an average size ranging from 166.9 ± 14.1 to 305.2 ± 16.2 nm with 0.19–0.26 of polydispersity index (PDI), and a surface …

Beyond Surrealism: The Developing Keyboard Style Of André Souris, Melanie T. Mallard

LSU Doctoral Dissertations

André Souris (1899-1970) is perhaps best known as a musical contributor to the Belgian surrealist group founded by Paul Nougé, but he assumed many roles throughout his life, including composer, writer, director, and promoter of modern music. His various interests influenced the style of his compositions, which remain largely unpublished and have received little scholarly attention beyond researchers of surrealism. Through this survey of many of Souris’ works for keyboard, I attempt to lay the groundwork for further discussion about Souris’ musical contributions not only through the lens of surrealism but also throughout his compositional career. This descriptive analysis of …

Measuring And Modeling Grease Degradation, Alan Gurt

LSU Doctoral Dissertations

Lubricating grease is an ideal lubricant for many devices such as roller bearings, journal bearings, slide bearings, gears, and many types of joints due to its simplicity. Once grease is put in place, it can often provide adequate lubrication for extended periods of time without the need for a complex supply system that would generally be needed for oil lubrication. However, during prolonged use, various degradation mechanisms change the physical and chemical properties of grease, possibly leading to inadequate performance and machinery failure.

In order to succinctly quantify the degradation of grease, it is essential to have robust, meaningful test …

Forensicllm: A Local Large Language Model For Digital Forensics, Binaya Sharma

LSU Master's Theses

Large Language Models (LLMs) excel in diverse natural language tasks but often lack specialization in fields like digital forensics. Their reliance on cloud-based APIs or high-performance computers restricts their use in resource-limited environments, and response hallucinations could compromise their applicability in forensic contexts. We introduce ForensicLLM, a 4-bit quantized LLaMA-3.1-8B model fine-tuned using Retrieval Augmented Fine-tuning (RAFT) on 6,739 Q&A samples extracted from 1,082 digital forensic research articles and curated digital artifacts. Evaluation on 2,244 Q&A samples showed that ForensicLLM outperformed the base LLaMA-3.1-8B model by 4.06%, 5.43%, and 15.79% on BERTScore F1, BGE-M3 cosine similarity, and G-Eval, respectively. Compared …

Evaluating Growth Of Coastal Grass In Recycled Glass Sand: Evidence For Safe Application In Coastal Restoration, Allison B. Huddleston

Honors Capstones

Louisiana’s coastal land loss results from complex interactions of anthropogenic and naturally occurring processes that impact sediment supply in the Mississippi river delta. Given the coastline's vital role in the state’s economy, Louisiana has made significant investments in coastal restoration projects, including planting native vegetation and adding borrowed sediments. The amount of sediment needed to maintain Louisiana’s existing coastline exceeds the available amount that could be extracted, and state officials have since identified this lack of sustainable sediment resources as a critical limitation for future restoration projects. One proposed solution to address this shortage is using recycled crushed glass cullet …

Mobilizing The Masks Of Carnaval For A Re-Reading Of Zobel's Rue Cases-Nègres, Benjamin E. Tilson

Tête à Tête: Journal of Francophone Studies

The identity of Caribbean literature, subject to the forces of domination and exclusion, has long been contested from both within and outside of its field. Alternately described as imitating, reappropriating, indigenizing and reductionist, Caribbean writers have sought to carve out a space for works that are received as authentic without recourse to fetishes. Drawing upon the works of Maryse Condé, the Creolists and anthropologic studies of Carnaval, the present work attempts to analyze what might be termed alternative narratives, characters and symbols in Joseph Zobel’s novel La Rue Cases-Nègres and its filmic adaptation by Euzhan Palcy through the lens of …

Des Rois Anglais Qui Parlent Français : Une Etude Sur La Situation Linguistique En Angleterre Après La Conquête Normande, Trent Dunkin

Tête à Tête: Journal of Francophone Studies

Prior to 1066, England was ruled by the Germanic speaking Anglo-Saxons. However, after the defeat of Harold II at the Battle of Hastings, William the Conqueror became King of England, ushering in a lengthy era in which English monarchs were primarily francophone. This article explores the linguistic situation in England before, during, and after the Norman Conquest of 1066. Specifically, this article looks at the Anglo-Norman dialect as a distinct Langue d’Oïl, focusing primarily on its phonetics, syntax, and orthography, using examples found in Laüstic and Chèvrefeuille, two lais written by Marie de France in the late 12 …

De La Saleté A La Poésie : Portrait De La France Périphérique Dans L’Été Des Charognes De Simon Johannin, Julie Catel

Tête à Tête: Journal of Francophone Studies

Simon Johannin's debut novel, "L'Été des charognes," published in 2017, offers a vivid portrayal of life in La Fourrière, an isolated village located in the Vosges. This area falls within what the French sociologist Christophe Guilluy terms 'France périphérique,' which refers to rural regions plagued by poverty and a sense of neglect. Through the perspective of an adolescent narrator, Johannin depicts the village's harsh daily reality, emphasizing its pervasive violence and the filth that characterizes its landscape. The narrative is saturated with descriptions of unpleasant odors, particularly from the decomposing carcasses of farm animals awaiting disposal, which permeate the village …

Euphemism In Ai Discourse As Colonial Harm & Effect: Learnings From Subaltern Puerto Rico, Jacqueline Oquendo

LSU Doctoral Dissertations

Through three integrated studies, this dissertation explores complex human-AI interactions by comparing the perceptions of two groups of U.S. citizens: subaltern Puerto Ricans and stateside Americans’ interactions with ChatGPT. This corpus-assisted Critical Discourse Analysis or CLCDA, triangulated with 1:1 semi-structured interviews, validates scholars’ concerns about the biases inherent in generative AI. Contributing to those concerns, this dissertation reveals that ChatGPT deploys discourse strategies that, when executed, facilitate digital colonialism. Euphemistic language is prominent among its discourse strategies, replacing controversial words, phrases, and topics with more palatable ones. When prompted on events of historical significance, I find that ChatGPT’s discourse obscures …

Body, Mind, And Archives: A Critical Questioning Of “Places For Knowledge” In David Treuer’S The Translation Of Dr. Apelles, Lisa Brau-Weglinski

Comparative Woman

Western conceptualizations of time and space are common topics to be queried within the field of Indigenous literary study. However, while the focus has been laid on temporal and spatial literary conventions, too little attention has been drawn to the conceptualization and norms around an identity forming element: knowledge. This paper is particularly suspicious of Western conceptualizations of “places for knowledge,” as this has very real consequences for how we understand and treat ourselves and others. As such, my work highlights that “places for knowledge” can cloud and limit our perception of reality, which, concerning the project of decolonization …

Mapping Gender And Territory: The Continent Allegories On European World Maps From The Late Middle Ages To The Renaissance Until The Early Enlightenment, Katharina Eva Oehmichen

Comparative Woman

The four-part set of female continent allegories, which originated in the early Renaissance, was born out of a European need for a new vehicle of thought that served the functions of representing imperial expansion and the superiority of Western science and civilization, while gratifying the curiosity of the readers about newly discovered lands at the same time. The shift from the Christian symbolic tradition of the representation of the continents on world maps mirrored the shift in Western perception and knowledge of the world and Europe’s position in it. Apart from geo-political and imperial agendas that might have favored a …

Living Losses, Courtney A. Brown Phd

Comparative Woman

Contextually, I am from a line of strong black women. I am from a community of strivers and survivors who’ve accomplished great things through the blanket of patriarchy and civil injustices. I stand on the shoulders of many who took literal and figurative hits so that I could have opportunities they only dreamed of. I have followed in this legacy shattering glass ceilings into unrecognizable pieces for those who will come next.

However, breaking through has not come without cuts, bruises, scrapes and wounds. The celebration of smashing stereotypes should at least be balanced with the acknowledgement of the formidable …

Assessing The Influence Of Occupancy Factors On Energy Performance In Us Small Office Buildings, Seddigheh Norouziasl, Sorena Vosoughkhosravi, Amirhosein Jafari, Zhihong Pang

Faculty Publications

Office buildings are responsible for about 35% of the total electricity in the US and over 70% of building energy consumption occurs during occupancy periods. Therefore, understanding occupancy behavior is crucial for reducing building energy consumption. However, given the stochastic nature of occupant behavior, identifying which occupancy parameters have the most impact on energy consumption poses a considerable challenge. This study aims to investigate and quantify the impact of various occupancy parameters on the energy performance of a US small-sized office building using an EnergyPlus-based nationwide energy simulation. First, dynamic occupancy schedules are created based on different occupancy parameters using …

Calculation And Comparison Of Step Guidelines For Preschooler Physical Activity While Indoors, Halle Roman, Leanne M. Redman, Cody D. Neshteruk, Derek Hales, Brian Helsel, Chelsea L. Kracht

Clinical Research Faculty Publications

Objectives: Preschooler physical activity (PA) is vital for growth and development. The World Health Organization PA guidelines state preschoolers should achieve ≥ 180 min/day of Total PA (TPA) of which ≥ 60 min is moderate-to-vigorous PA (MVPA). A step/day recommendation to match these guidelines may be a more practical metric for caregivers to promote PA. The purpose of our investigation is to improve upon existing step recommendations by creating one for indoor-based activities, acknowledging where preschoolers spend most of their time, and various cut-points for PA. Methods: In a laboratory study (Aim 1), a validated direct observation protocol was used …

Division of Basic Science Faculty Publications

Objective: Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) are effective procedures to treat and manage type 2 diabetes (T2D). However, the underlying metabolic adaptations that mediate improvements in glucose homeostasis remain largely elusive. The purpose of this study was to identify metabolic signatures associated with biochemical resolution of T2D after medical therapy (MT) or bariatric surgery. Research Design and Methods: Plasma samples from 90 patients (age 49.9 ± 7.6 years; 57.7% female) randomly assigned to MT (n = 30), RYGB (n = 30), or SG (n = 30) were retrospectively subjected to untargeted metabolomic analysis using ultra performance liquid …

Validation Of The Quick Mild Cognitive Impairment Screen In An American Sample Of Patients With Mild Cognitive Impairment And Mild Dementia, Dariella A. Fernandez, Suzanne Schmitz, Heather Foil, Robert Brouillette, Jeffrey N. Keller, Robin C. Hilsabeck

Clinical Research Faculty Publications

Objective: Early detection of cognitive impairment is critical for patient outcomes, yet cognitive impairment is under identified in primary care settings largely due to time constraints. The Quick Mild Cognitive Impairment (Qmci) screen was developed to address the need for a short cognitive screening instrument (< 5 min) that is sensitive to early cognitive change but has not been validated in the United States (US). The objective of this study was to examine the classification accuracy of the Qmci in participants from two memory specialty (e.g., secondary outpatient) clinics in the US. Methods: Participants were 152 older adults: 87 participants were cognitively normal (CN), 48 were diagnosed with mild cognitive impairment (MCI) and 17 were diagnosed with mild dementia (DEM). Classification accuracy of the Qmci and Mini Mental State Examination (MMSE) were compared in participants with and without cognitive impairment. Results: The Qmci demonstrated higher classification accuracy in differentiating CN from cognitively impaired participants (i.e., MCI and DEM) (AUC = 0.82) than the MMSE (AUC = 0.77). The optimal cut-off score for the Qmci was < 67, which achieved a sensitivity of 79% and specificity of 80%. The optimal MMSE cut-off score was < 27, which achieved a sensitivity of 97% and specificity of 43%. Conclusions: The Qmci is a valid cognitive screening instrument for detecting early stages of cognitive impairment in memory clinic samples in the US. Its short administration time and increased specificity for detecting MCI make it an attractive option for use in primary care settings. Further validation of the Qmci is needed, specifically within primary care settings.
