Surface And Bulk Properties Of Multi-Component Metal Alloys, Frank A. Mckay Iii
Surface And Bulk Properties Of Multi-Component Metal Alloys, Frank A. Mckay Iii
LSU Doctoral Dissertations
While HEAs have been studied extensively for their material properties, their potential as catalysts remains widely unexplored. To explore the feasibility of CoCrFeNi as a catalyst for the hydrogen evolution reaction, the results of X-ray photoelectron spectroscopy (XPS) and high-resolution electron energy loss spectroscopy (HREELS) experiments are compared to electrochemical experiments and theoretical calculations. XPS shows that this surface forms passive oxides with a propensity of Cr > Fe > Co, with no evidence of Ni oxidation. From comparison to calculations, it is shown that the electrochemical activity is enhanced in a partially oxidized state. The lack of Ni oxidation suggests that …

Coastal waters often experience enhanced ocean acidification due to the combined effects of climate change and regional biological and anthropogenic activities. Through reconstructing summertime bottom pH in the northern Gulf of Mexico from 1986 to 2019, we demonstrated that eutrophication-fueled respiration dominated bottom pH changes on intra-seasonal and interannual timescales, resulting in recurring acidification coinciding with hypoxia. However, the multi-decadal acidification trend was principally driven by rising atmospheric CO2 and ocean warming, with more acidified and less buffered hypoxic waters exhibiting a higher rate of pH decline (− 0.0023 yr− 1) compared to non-hypoxic waters (− 0.0014 yr …

Running To Or Running From: Exploring The Phenomenology Of Off-Cycle Turnover In Entry Level Housing Professionals, Kate Gannon-Cullinan
LSU Doctoral Dissertations
Housing and residence life as a functional area serves as a major entry point for careers in higher education and student affairs. With the majority of annual job postings within entry-level, live-in housing roles, the future of the field may well be predicted in these high-impact, high-turnover positions on college campuses. As these functional areas continue to struggle to find themselves fully-staffed throughout their academic year cycle, the impact on both the student experience and organizational health is impacted. This study utilized an interpretive phenomenological approach to explore the experiences and feelings of those entry-level, live-in housing professionals who chose …
Investigating Gulf Coast Aquifer System: Stratigraphy Reconstruction, Inverse Modeling, And Groundwater Stress Assessment, Shuo Yang
LSU Doctoral Dissertations
The Mississippi Embayment aquifer system (MEAS) and the Coastal Lowlands aquifer system (CLAS) provide substantial groundwater resources for human activities in the U.S. Gulf Coastal Plain. However, the overexploitation has led to groundwater depletion in the MEAS and the CLAS, threatening sustainable groundwater use. Such concern highlights the crucial need for an advanced understanding of stratigraphy and groundwater in these aquifer systems, which is essential for effective regional groundwater management. This dissertation presents a comprehensive investigation of MEAS and CLAS in the Louisiana and southwestern Mississippi region, encompassing three fundamental dimensions: stratigraphy reconstruction, groundwater modeling, and groundwater stress assessments. A …

In-Person, Hybrid, Or Remote: Exploring The Effectiveness Of Teacher Practices On Student Performance During The Covid-19 Pandemic, Ashley M. Segalla
LSU Doctoral Dissertations
Schools and universities had to make unexpected changes beginning in Spring 2020 because of the COVID-19 pandemic. In Spring 2021, one university in the southern region of the United States implemented hybrid teaching formats in College Algebra courses, where students attended half of the classes in-person, and the remaining half of classes were attended synchronously and remotely. The purpose of this mixed methods study was to determine if students’ attendance methods (virtual or in-person) impacted their academic performance in the course. Additionally, the study sought to determine how students and the instructor felt student performance was impacted by hybrid attendance. …

Reconsidering The Reliability Of Chemical Process Simulators I: Implementation Of The Murphree And Vaporization Efficiencies, Zachary Braswell, Brian F. Hanley, Holt Ragsdale
Faculty Publications
Most chemical process simulators in widespread use today allow users to apply some type of efficiency correction to individual equilibrium stages or to equilibrium stage sections in order to align the stage or section separation performance more closely to actual tray performance in the field. Some simulators even allow for the use of component efficiencies on individual stages or in stage sections. It is our contention, however, that two of the more commonly available efficiency models, the vaporization efficiency and Murphree vapor phase efficiency, have generally been implemented incorrectly. The three major conceptual inconsistencies are (1) the assumption that the …

Pal-Bert: An Improved Question Answering Model, Wenfeng Zheng, Siyu Lu, Zhuohang Cai, Ruiyang Wang, Lei Wang, Lirong Yin
Faculty Publications
In the field of natural language processing (NLP), there have been various pre-training language models in recent years, with question answering systems gaining significant attention. However, as algorithms, data, and computing power advance, the issue of increasingly larger models and a growing number of parameters has surfaced. Consequently, model training has become more costly and less efficient. To enhance the efficiency and accuracy of the training process while reducing the model volume, this paper proposes a first-order pruning model PAL-BERT based on the ALBERT model according to the characteristics of question-answering (QA) system and language model. Firstly, a first-order network …
Computational Design Of An Electro-Organocatalyst For Conversion Of Co2 Into Formaldehyde, Foroogh Khezeli, Craig Plaisance
Computational Design Of An Electro-Organocatalyst For Conversion Of Co2 Into Formaldehyde, Foroogh Khezeli, Craig Plaisance
Faculty Publications
Density functional theory calculations employing a hybrid implicit/explicit solvation method were used to explore a new strategy for electrochemical conversion of CO2 using an electro-organocatalyst. A particular structural motif is identified that consists of an electron-rich vicinal enediamine (>N-C═C-N<) backbone, which is capable of activating CO2 by the formation of a C-C bond while subsequently facilitating the transfer of electrons from a chemically inert cathode to ultimately produce formaldehyde. Unlike transition metal-based electrocatalysts, the electro-organocatalyst is not constrained by scaling relations between the formation energies of activated CO2 and adsorbed CO, nor is it expected to be active for the competing hydrogen evolution reaction. The rate-limiting steps are found to occur during two proton-coupled electron transfer (PCET) sequences and are associated with the transfer of a proton from a proton transfer mediator to a carbon atom on the electro-organocatalyst. The difficulty of this step in the second PCET sequence necessitates an electrode potential of −0.85 V vs RHE to achieve the maximum turnover frequency. In addition, it is postulated that the electro-organocatalyst should also be capable of forming long-chain aldehydes by successively carrying out reductive aldol condensation to grow the alkyl chain one carbon at a time.
Examining The Effects Of Differential Reinforcement And Time-Out On Unsafe Playground Behavior, Elizabeth K. Linton
Examining The Effects Of Differential Reinforcement And Time-Out On Unsafe Playground Behavior, Elizabeth K. Linton
LSU Master's Theses
The purpose of this study was to examine the effects of differential reinforcement (DRO) without extinction, and then the additive effects of time-out, on reducing unsafe playground behavior. The results of the DRO in isolation phase indicated that DRO alone was only consistently effective in reducing or eliminating unsafe behavior for one out of four participants. The other three participants moved on to the multielement comparison where the combination of DRO and time-out (DRO+TO) condition was added. The DRO+TO condition reduced and eliminated unsafe playground behavior for all participants who experienced the condition. Those participants engaged in higher levels of …

Objective: T lymphocytes from visceral and subcutaneous white adipose tissues (vWAT and sWAT, respectively) can have opposing roles in the systemic metabolic changes associated with obesity. However, few studies have focused on this subject. Claudin-1 (CLDN1) is a protein involved canonically in tight junctions and tissue paracellular permeability. We evaluated T-lymphocyte gene expression in vWAT and sWAT and in the whole adipose depots in human samples. Methods: A Clariom D-based transcriptomic analysis was performed on T lymphocytes magnetically separated from vWAT and sWAT from patients with obesity (Cohort 1; N = 11). Expression of candidate genes resulting from that analysis …

In the colonisation of Queensland, Australia it is commonly accepted that large numbers of Indigenous people were killed in the second half of the nineteenth century. Calculations of violent mortality have recently been revised radically upwards. We suggest that the methodology deployed in these new studies is unreliable, reflecting errors in counting and calculation, as well as underestimating the selection bias of the samples. We caution against projecting aggregate violent mortality where the underlying data are so imperfect and emphasise the value of more detailed local and regional studies to inform better understanding of colonisation's impact on First Peoples.

During 25 surveys of global Phytophthora diversity, conducted between 1998 and 2020, 43 new species were detected in natural ecosystems and, occasionally, in nurseries and outplantings in Europe, Southeast and East Asia and the Americas. Based on a multigene phylogeny of nine nuclear and four mitochondrial gene regions they were assigned to five of the six known subclades, 2a-c, e and f, of Phytophthora major Clade 2 and the new subclade 2g. The evolutionary history of the Clade appears to have involved the pre-Gondwanan divergence of three extant subclades, 2c, 2e and 2f, all having disjunct natural distributions on separate …

Humans have profoundly impacted the distribution of plant and animal species over thousands of years. The most direct example of these effects is human-mediated movement of individuals, either through translocation of individuals within their range or through the introduction of species to new habitats. While human involvement may be suspected in species with obvious range disjunctions, it can be difficult to detect natural versus human-mediated dispersal events for populations at the edge of a species' range, and this uncertainty muddles how we understand the evolutionary history of populations and broad biogeographical patterns. Studies combining genetic data with archaeological, linguistic and …

Advancing ecological restoration assessments requires a more detailed consideration of species interactions and ecosystem processes. Most restoration projects rely on a few metrics not always directly linked with ecological theory. Here, we used Odum's theory of ecosystem development to assess and compare the ecosystem structure and services of created marshes (4–6 years old) with preexisting, reference marshes in a brackish water region of the Mississippi River Delta. We built ecosystem models for created and reference marshes that integrated large datasets of stomach contents, stable isotopes, and taxa abundances. Despite strong resemblance in community structure, created marshes were at an earlier …

This thesis analyzes the author’s production of three intercultural, multisensory films situated in New Orleans, encompassing elements both narrative and documentary genres. Intercultural cinema exists in a setting where people of different cultural backgrounds live together in power-inflicted spaces of diaspora, colonialism, and cultural apartheid and the development of the story is centered around exoticism, fetishization, and fascination with the other (Marks 2007, 1). Multisensory media primarily engages through visual perception and auditory input, which create cultural knowledge stored as long-term memory files in the brain (Marks 2007).

The mergers of binary compact objects such as neutron stars and black holes are of central interest to several areas of astrophysics, including as the progenitors of gamma-ray bursts (GRBs)1, sources of high-frequency gravitational waves (GWs)2 and likely production sites for heavy-element nucleosynthesis by means of rapid neutron capture (the r-process)3. Here we present observations of the exceptionally bright GRB 230307A. We show that GRB 230307A belongs to the class of long-duration GRBs associated with compact object mergers4–6 and contains a kilonova similar to AT2017gfo, associated with the GW merger GW170817 (refs. 7–12). …

Molecular motors (MM) are molecular machines, or nanomachines, that rotate unidirectionally upon photostimulation and perform mechanical work on their environment. In the last several years, it has been shown that the photomechanical action of MM can be used to permeabilize lipid bilayers, thereby killing cancer cells and pathogenic microorganisms and controlling cell signaling. The work contributes to a growing acknowledgement that the molecular actuation characteristic of these systems is useful for various applications in biology. However, the mechanical effects of molecular motion on biological materials are difficult to disentangle from photodynamic and photothermal action, which are also present when a …
