Spatiotemporal Patterns In Orbicella Faveolata Wound Regeneration As An Indicator Of Colony Health, Alexander G. Wheeler

All HCAS Student Capstones, Theses, and Dissertations

Anthropogenic (e.g. damage from anchors, scuba divers, tissue sampling) and natural disturbances (e.g. predation, storm damage) can result in wounding of live tissue on coral colonies. Wounding has been shown to detract from a common resource pool, increasing disease susceptibility and impairing coral growth and reproductive activity. Regeneration not only varies between species, but also between conspecifics in the same location. A colony’s capacity to regenerate tissue can be an indicator of a colony’s condition and resilience. Understanding the physiological and environmental factors that affect tissue regeneration alongside the ultimate impact of sampling (disease and predation correlations) are needed for …

ABSTRACT

Mindfulness Matters: Addressing Anxiety and Navigating Toward Wellbeing Through MIEA Mindfulness Practices, a Mixed-Methods Study of LGBTIQ Graduate Writing Students

Anxiety has always been a part of the human experience, even before the phenomenon was conceptualized in the 17^th century and named by Freud in the 19th. And human beings have devised many strategies for addressing anxiety: reducing it, ignoring it, distracting oneself from it, despairing over it, medicating it, engaging with it, moving through it, co-existing with it. The current zeitgeist, more than four years into the COVID-19 global pandemic, situates anxiety as a central facet of …

Using Additive Manufacturing To Characterize Effects Of Sparse Infill Density And Sparse Infill Pattern On The Compressive Properties Of Short Strand Carbon Fiber Infused Petg, Luke C. Salisbury

Honors Theses

The advent of additive manufacturing has revolutionized the prototyping, design, and manufacturing of new and innovative products. Through the use of Fused Deposition Modeling (FDM), parts can be manufactured using different sparse infill percentages (the percentage of void space within a printed object) and sparse infill patterns (the lattice structure of material within the object). Through the manipulation of these variables, the same material and part can have different compressive and flexural properties. In addition to sparse infill, the thermoplastics used in fused deposition modeling can be reinforced with carbon fiber strands to create a printable composite material capable of …

Biological Control Of Roseau Cane Scale With Parasitoid Wasps In Louisiana, Tanner C. Sparks

LSU Doctoral Dissertations

Roseau cane scale, Nipponaclerda biwakoensis (Hemiptera: Aclerdidae) is an invasive species of scale insect negatively impacting Phragmites australis (Cyperales: Poaceae) stands within the Mississippi River Delta. The scales were first detected in 2017 from reports of Phragmites die-back within the MRD by landowners. Initial range surveys located RCS infested Phragmites stands were primarily limited to southeastern Louisiana with a single population near Port Arthur, Texas. Follow-up field surveys conducted annually from 2021 to 2023 monitoring further range expansion by the scale show the current range extends nearly 600 km between High Island, Texas and Bayou la Batre, Alabama.

Quantum Singular Oscillator With Potential Controlled By Position-Dependent Mass, Elchin Jafarov, Shakir Nagiyev

Turkish Journal of Physics

An exactly solvable model of a nonrelativistic quantum singular oscillator with a controlled potential is constructed. A position-dependent mass is introduced instead of a constant mass of the quantum system under consideration in such a way that it is possible to purposefully control the shape of the potential, turning it into a quantum well with different depths. It is shown that analytical expressions of the wave functions of such a quantum system are described through 2F1 type hypergeometric functions and Jacobi polynomials, whereas, the discrete energy spectrum corresponding to these analytic solutions is non-equidistant. In a specific limit, when the …

Seeing Beyond The Anthropocene With Joyce And Beckett, Michael Kane

Research Outputs: 2025-Present

This article suggests that the literary works of James Joyce and Samuel Beckett may offer a means of ‘seeing beyond the Anthropocene’. A close look at Joyce’s “The Dead” and the “Proteus” and “Penelope” episodes of Ulysses as well as at Beckett’s play Endgame and other works will show how these writers’ distinct ways of looking at the world, and the life and death of mortal human beings, provide radical critiques of (and perhaps alternatives to) anthropocentric idealism. Their insights are still highly relevant today as the ecological crisis demands a fundamental reorientation of the (post)human relationship with the earth.

Transcriptional Regulation In The Absence Of Inositol Trisphosphate Receptor Calcium Signaling, Michael Young, David M. Booth, David Smith, Marco Tigano, György Hajnóczky, Suresh K. Joseph

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

The activation of IP3 receptor (IP3R) Ca2+ channels generates agonist-mediated Ca2+ signals that are critical for the regulation of a wide range of biological processes. It is therefore surprising that CRISPR induced loss of all three IP3R isoforms (TKO) in HEK293 and HeLa cell lines yields cells that can survive, grow and divide, albeit more slowly than wild-type cells. In an effort to understand the adaptive mechanisms involved, we have examined the activity of key Ca2+ dependent transcription factors (NFAT, CREB and AP-1) and signaling pathways using luciferase-reporter assays, phosphoprotein immunoblots and whole genome transcriptomic studies. In addition, the diacylglycerol …
