Effects Of Alkylation On Potency Of Benz[A]Anthracene For Ahr2 Transactivation In Nine Species Of Freshwater Fish, Justin Dubiel, Hunter Johnson, Andreas N.M. Eriksson, A. Hontela, Jon A. Doering, Steve Wiseman

Faculty Publications

Polycyclic aromatic hydrocarbons (PAHs) are naturally occurring or anthropogenic organic chemicals that can activate the aryl hydrocarbon receptor 2 (AhR2) and induce toxicity in fishes. Alkyl PAHs are more abundant than nonalkylated PAHs in certain environmental matrices and there is growing evidence that alkylation can increase potency, dependent on the position of alkylation. However, it is unknown if the effect of alkylation on potency is conserved across species. In addition, relatively little is known regarding the extent of interspecies variation in sensitivity to PAHs and alkyl PAHs. Therefore, objectives of the present study were to characterize potency of benz[a]anthracene (BAA) …

Simulation Of Radioactive Plume Transport In The Atmosphere Including Dynamics Of Particle Aggregation And Breakup, Alexander I. Wiechert, Austin P. Ladshaw, Yong Ha Kim, Costas Tsouris, Sotira Yiacoumi

Faculty Publications

Accurate prediction of the atmospheric transport of debris particles relies heavily on our knowledge of the size distribution of the particles within a debris cloud. Assuming a fixed particle size during simulations is not always viable since the size distribution of the debris can change during transport. Various microphysical processes, such as aggregation and breakup, influence debris particles and dictate any changes to the size distribution. To track those changes that can occur, a population balance model can be adopted and instituted within a model framework. Nonetheless, many of the models that simulate the transport of radioactive debris following a …

Reducing The Generation Time In Winter Wheat Cultivars Using Speed Breeding, Adam Schoen, Sydney Wallace, Meghan Fisher Holbert, Gina Brown-Guidera, Stephen Harrison, Paul Murphy, Nicholas Sanantonio, David Van Sanford, Richard Boyles, Mohamed Mergoum, Nidhi Rawat, Vijay Tiwari

Faculty Publications

Reducing generation time is critical to achieving the goals of genetic gain in important crops like wheat (Triticum aestivum). Speed breeding (SB) has been shown to considerably reduce generation times in crop plants. Unlike spring wheat cultivars, winter wheat varieties require typically 6–9 weeks of cold treatment, called vernalization, for flowering which extends the generation time for the development of improved winter wheat cultivars. Here, we optimized the SB method using a set of 48 diverse soft red winter wheat (SRWW) cultivars by testing vernalization duration, light and temperature requirements, and the viability of seeds harvested after different durations post-anthesis …

Measuring Resilience To Sea-Level Rise For Critical Infrastructure Systems: Leveraging Leading Indicators, Lamis Amer, Murat Erkoc, Rusty A. Feagin, Sabarethinam Kameshwar, Katharine J. Mach, Diana Mitsova

Faculty Publications

There has been a growing interest in research on how to define and build indicators of resilience to address challenges associated with sea-level rise. Most of the proposed methods rely on lagging indicators constructed based on the historical performance of an infrastructure sub-system. These indicators are traditionally utilized to build curves that describe the past response of the sub-system to stressors; these curves are then used to predict the future resilience of the sub-system to hypothesized events. However, there is now a growing concern that this approach cannot provide the best insights for adaptive decision-making across the broader context of …

Adaptive Quantum Information Processing In Non-Equilibrium Environments, Arshag Danageozian

LSU Doctoral Dissertations

Solid state and condensed matter systems, such as diamond impurities, superconductors, quantum dots, and ion traps, constitute important physical platforms for various applications in quantum information processing (QIP). However, it has consistently been shown that all such modern platforms suffer from non-equilibrium behavior on timescales that are relevant for many important QIP tasks. The causes range from intrinsic non-equilibrium dynamics (e.g. in diamond) to the presence of various impurities with their own internal dynamics (e.g. in superconductors and quantum dots) or variations in the control fields used to stabilize the quantum matter (e.g. in ion traps). When reserving degrees of …

Reasoning The Voice: Toward A Diagnostic And Prescriptive Technique In The Teaching Of Singing, Carlos E. Santelli

LSU Doctoral Dissertations

Voice pedagogy literature often draws a parallel between a doctor’s ability to diagnose illness and prescribe treatment, and a voice teacher’s ability to identify vocal obstacles and design solutions. The core of these parallel procedures lies in an ability to utilize critical reasoning skills within highly specific contexts. Medical literature describes this as “clinical reasoning” and has studied it as a learned process. Voice pedagogy literature has traditionally described this as an innate process which is solely developed through experience. This document broadly examines the ways in which medical literature has broken down clinical reasoning into specific cognitive processes and …

Cycles And Dynamic Correlations Between Agricultural And Stock Markets, Junior E. Betanco Gunera

LSU Master's Theses

This study conducts two interrelated econometric analyses; it first analyzes the cyclical relationship between stock and commodity markets and second, it studies the dynamic conditional correlation between them. The cyclical analysis uses the bandpass filter proposed by Christiano-Fitzgerald (2003) to isolate the trend component in the long-run relationship of stocks relative to commodity markets. The results show that stock and commodities have alternated in return leadership nine times during the last 151 years, three full cycles (from peak to peak) can be clearly identified, each one with an average duration of 31 years. While the COVID-19 pandemic had little impact …

A Comparison Of Self-Report Measures To Screen For Mental Health Concerns In Youth, Jacob Landon Deboer

LSU Doctoral Dissertations

Proactive screening for treatable conditions is not a new concept. Instead, screening has been present in the United States since at least the early 1900s. Accordingly, many schools actively screen for academic problems, yet the same attention is not paid to mental health. Past research estimates that one out of five children in the U.S. has a mental health disorder. However, recent research conducted during the COVID-19 pandemic has found these numbers to be increasing. Additional estimates suggest that only one-third of children with a mental health disorder receive treatment. Schools have a role to play in addressing the identification …
