Zinc-Based Amendments And Zn-Solubilizing Beneficial Bacteria Mitigate Lead-Induced Toxicity In Chickpea (Cicer Arietinum L.), Mohammad Shahid, Mohammad Abul Farah, Khalid Mashay Al-Anazi, Leonard Koolman

Research Outputs: 2025-Present

Lead (Pb) is a toxic metal that disrupts plant physiological processes and poses significant human health risks. Fertilizers, nanomaterials, and mineral-solubilizing plant growth-promoting rhizobacteria (PGPR) support phytoremediation as an emerging, eco-friendly strategy for metal detoxification by improving nutrient availability and minimizing metal toxicity in plants. This study explored the interactions of Zn-fertilizer, zinc-oxide nanoparticles (ZnO-NPs), and Zn-solubilizing Enterobacter cloacae (Zns-Ec) in mitigating Pb-induced phytotoxicity in 50, 100, and 150 mgPbkg ⁻¹ soil-stressed chickpea. Under Pb stress. Zn, ZnO-NP and Zns-Ec significantly (p < 0.05) improved root biomass (23.4, 52.3, and 71.4%), chl a (21.2, 26.5, and 39.8%), and carotenoids (26.7, 29.7 and 45.7%) in chickpea subjected to 50 mgPbkg ⁻¹ soil. Zn, ZnO-NP and Zns-Ec interactions reduced lipid peroxidation (LPO), hydrogen peroxide (H ₂O ₂) …

Genocidal Accusation, Steven Arrigg Koh

Faculty Scholarship

To accuse of genocide — what does it mean? Genocidal accusation is ubiquitous today, evident more in the public square than in any courtroom. At first glance, such accusation seemingly relies on a central assumption: genocidal accusation is critical to preventing atrocity. This Article argues that this widespread assumption is incomplete, obscuring genocidal accusation’s dual nature. In fact, genocidal accusation encompasses not only laudable atrocity prevention (for example, the Rwandan genocide), but also problematic punitive, carceral discourse that brands the “other” as morally polluted (such as President Putin’s Ukraine invasion). It is thus challenging to evaluate such accusation in the …

Looking past the script, this project explains how to add depth to the characters in ways that shape their visual direction. It shows how those character choices influence body language, acting, and the environments around them, emphasizing the importance of composition, camera work, and the way a scene’s framing depends on the personality and …

Intentional Improvement Through 3d Environment Art, Samuel T. Pinnex

Master of Fine Arts in Digital Media Culminating Experience

The idea of self-growth can be exciting—the thought of where one might be in the near or distant future is exhilarating. As an artist, this is even more apparent. On the other side of that coin, the realization that it is all up to you can oftentimes be overwhelming. We all want to improve, and we want our work to improve with us as a showcase of that improvement. Over the past two years, I’ve learned how valuable it is to adopt a “growth mindset”. Once I became comfortable with this idea, the responsibility for my own self-growth no longer …

Advancing Anesthesia Provider Proficiency In Airway Assessment Using Point-Of-Care Ultrasound: An Osce-Based Educational Initiative, Austin Fike, Trevor Jordan, Sam Sherrill Iii

Doctoral Projects

Airway management is one of the fundamental pillars of anesthesia. Traditionally, tools such as the Mallampati classification and the thyromental distance are used for airway assessment in the perioperative area. However, often, these methods fail to reliably predict difficult intubations. The use of point-of-care ultrasound (POCUS) has emerged as a valuable adjunct in airway assessment. However, a knowledge deficit exists among anesthesia providers regarding its application in airway assessments for perioperative adult patients. This doctoral project addressed the knowledge deficit in POCUS airway assessment among Certified Registered Nurse Anesthetists (CRNAs) and Student Registered Nurse Anesthetists (SRNAs) through the development and …

Fungal Biodiversity, Microbial Communities, And Ecosystem Function In Non-Perennial Streams, Charles T. Bond

Dissertations

A global majority of steams are non-perennial, drying at some point in time and space. Despite the vital roles that fungi and other microbes play in stream ecosystems, most research on stream microbiomes comes from perennial (continuously flowing) streams. The present series of studies addresses this research gap by examining microbial community composition and function in non-perennial streams, with an emphasis on fungi. Chapter I reviews existing scientific literature on the ecological processes that shape microbiome structure and function in non-perennial streams and outlines the varieties of fungi that may live there. Chapter II uses rDNA metabarcoding to survey fungal …

The Genetic And Environmental Determinants Of Stress Resilience Across Model Systems, Carson Len Stacy

Graduate Theses and Dissertations

Survival in fluctuating environments demands that organisms effectively anticipate and respond to future challenges. This capacity is shaped by both genetic background and environmental context. In this dissertation, I apply a population aware lens to explore how genetic diversity and environmental conditions intersect to shape stress survival. Integrating functional genomics and transcriptomics in Saccharomyces cerevisiae (brewer’s yeast) and a vertebrate (common canary) system, I dissect gene-by-environment (GE) interactions that underpin resilience. First, I move beyond a single reference genome by using a pan-genomic CRISPR knockout screen to assess osmotic stress survival across diverse S. cerevisiae isolates. This analysis reveals a …

Pharmacy

The current research proposes the preparation of Moxifloxacin-loaded solid lipid nanoparticles through a solvent-free double emulsion technique, to overcome chronic wound healing limitation. The independent variables: stearic acid, Span 80, and Tween 80 were optimized via Box–Behnken design, based on entrapment efficiency (EE%), zeta potential (ZP), and particle size (PS). To statistically optimize the formulation variables, a three-factor, three-level (3³) design involving 15 runs was employed and optimization was carried out to attain maximum EE% and ZP and minimum PS yielding an overall desirability of 0.851. Results indicated that increasing stearic acid enhanced EE%, Span 80 increase PS, and Tween …

Why The Long Face? The Distribution And Niche Of The Imperiled Narrow-Faced Kangaroo Rat (Dipodomys Venustus), Garrett L. Gimbel

Master's Theses

Distribution models provide a practical use case of connecting ecological niche theory with species’ occurrence and assemblages. By explicitly linking Hutchinson’s “niche space” with geographic space researchers can gain valuable information on a species’ niche characteristics and interactions, thereby informing conservation and management practices. The narrow-faced kangaroo rat (Dipodomys venustus) is a highly understudied kangaroo rat species endemic to the central coast of California and is an ideal species to explore niche theory in distribution modeling. Three subspecies are currently recognized: The Santa Cruz kangaroo rat (D. v. venustus), the elephant-eared kangaroo rat (D. v. …

Self-Determination Through Children's Rights: Resisting The Paradoxical Pretext Of Parents' Rights Legislation, Jeremiah Chin

Washington Law Review

Washington state law balances the interests of parents and the state in education, healthcare, and the general wellbeing of children. Despite the fact that children are at the center of emerging controversies, children’s rights are rarely discussed in state legislation debating the obligations and relationships between the state of Washington and parents. In education, for example, RCW 28A.605.005 finds “[p]arents are the primary stakeholders in their children’s upbringing.” While this may be true relative to the state, it overlooks the fact that children are the primary actors, agents, and rights bearers in their own personhood. This Article therefore considers ongoing …

Combating Antimicrobial Resistance In Asia: A Comprehensive Review Of Strategic Action Plans, Policies, And The Role Of The Who, Saud Almawash

Saudi Medical Journal

ABSTRACT Over the past 70 years, antimicrobial resistance (AMR) has emerged as a critical public health concern in Asia. Regional challenges such as dense population, scarce resources, and diverse healthcare systems further complicate the containment efforts. To address this, Asian countries have adopted several strategies and policies. A comprehensive review of published literature was conducted to identify key policies and interventions. Findings revealed diverse approaches to AMR containment, including surveillance and monitoring systems, antibiotic stewardship programs, infection control measures, vaccination strategies, and public health awareness campaigns. However, implementation of these strategies is hindered by resource, political, and regulatory barriers. The …

Analyzing The Impact Of Diet On Dusky Gopher Frog (Lithobates Sevosus) Development In Head Start Programs, Mckalyn Nelson

Honors Theses

Species are constantly impacted by human activity, directly or indirectly. One critically endangered species under investigation is the dusky gopher frog (Lithobates sevosus), which is an endemic species of frog found in the southeastern United States. Historically found from Louisiana to Alabama, a drought in 2002 narrowed the dusky gopher frog range even further. Head start programs have been shown to be effective in increasing population numbers; however, there is not much published data on the effectiveness of captive rearing diets for these programs. The dusky gopher frog head start program at the University of Southern Mississippi’s Lake …

Near-Infrared-Spectroscopy-Derived Oxygen Desaturation Rates During Post-Exercise Circulatory Occlusion As Predictors Of Cardiorespiratory Fitness Markers, Carstell Lee

Honors Theses

Cardiorespiratory fitness, measured as maximal oxygen consumption (VO₂max) is a critical predictor of all-cause mortality and overall cardiovascular health. Metabolic carts are the current gold standard for evaluation of VO₂max, but are inaccessible to most facilities and individuals, and are expensive ($20,000+). Near-Infrared spectroscopy (NIRS) has emerged as an accessible and affordable ($5,000-$10,000) alternative for evaluating skeletal muscle oxygenation kinetics and mitochondrial oxidative capacity. However, there is limited research in examining whether NIRS-derived oxygen desaturation rates can be a predictor of cardiorespiratory fitness markers (such as VO₂max and peak power output [PPO]), and whether these measurements show a superior predictive …

Brain and Mind Institute

The impacts of climate change in sub-Saharan Africa (SSA) presents a chronic and intensifying disaster, with drought, flooding, and extreme heat, presenting unique challenges and profound disruptions. Growing evidence links such events to ecological grief, ecological anxiety, and solastalgia – negative affective states that reflects responses to climate change related destruction of nature, species, culturally significant or sacred spaces, and other ways of life. While this literature is expanding in the Global North, little is known about how communities in SSA perceive and respond to deteriorating or depleting natural ecosystems. This article explores the ethnopsychology of distress precipitated by environmental …

Tracing The Journey Of Dissolved Organic Matter: From Leaf Litter Photodegradation To Microbial Processing In Tropical Streams, Samantha Nicole Sullivan

Chemistry & Biochemistry Theses & Dissertations

Dissolved organic matter (DOM) is a major reservoir of organic carbon in aquatic ecosystems and plays a central role in global carbon cycling through its transformation and remineralization to carbon dioxide (CO₂). As DOM moves from terrestrial environments into streams and rivers, its chemical composition is altered by a combination of microbial and photochemical oxidation processes that regulate both its reactivity and its persistence during transport. However, the molecular mechanisms governing these oxidative transitions, particularly in tropical ecosystems characterized by strong hydrologic seasonality and substantial inputs of plant-derived material, remain insufficiently resolved. This dissertation integrates ultrahigh-resolution mass spectrometry, optical characterization, …

Coupled Machine Learning Models: Combining Observations And Numerical Analysis In A Physics-Regularized Approach, Austin B. Schmidt

LSU New Orleans Theses and Dissertations

This dissertation investigates surrogate modeling for fixed-location environmental forecasting using novel data-combination techniques. The work surveys the landscape of observational measurements and numerically generated data, identifying similar research and gaps in current methodologies. The ratio-coupled training framework is introduced to combine two data sources per predicted feature through a tunable parameter that weights training signal strength. An optimization scheme is developed to simultaneously tune surrogate weights and the coupled signal ratio, allowing relative influence between signals to act as an explicit regularizer. Three case studies demonstrate the methodology and approach in a variety of contexts. The first study is based …
