An Integrated Data-Driven Framework For Coupling Upland Process Models And In-Stream Hydraulic Geometry Estimation, Ahmet Nazim Sahin

Electronic Theses and Dissertations

Large-scale watershed simulation platforms, such as the Agricultural Integrated Management System (AIMS), are essential for water resource management but are often limited by a critical lack of detailed in-stream channel data required for comprehensive river analysis. This study addresses this gap by developing and validating an integrated, data-driven framework that couples upland process models with in-stream hydraulic geometry estimation at a national scale. The research was executed through two complementary thrusts founded on the National Hydrography Dataset Plus (NHDPlus).

First, a geospatial workflow was developed to create NHDPlus-driven input files for the Annualized Agricultural Non-Point Source (AnnAGNPS) model—a tool for …

High-Resolution And Time-Efficient Infiltration Rate Estimating Technique Using Geophysical Emi And Hydrogeological Modeling, Md Abdus Samad

Electronic Theses and Dissertations

Information on infiltration rates is crucial for developing climate-resilient infrastructure, optimizing irrigation in agricultural management, and tackling stormwater-related hazards. However, rapid urbanization and climate change are expected to exacerbate these risks. Therefore, proper assessment and understanding of infiltration capacity is essential for designing effective soil conservation strategies aimed at enhancing infiltration, reducing erosion, and supporting sustainable land and water management. Despite the importance, traditional methods such as single ring and double ring infiltrometer (DRI) test are limited by spatial resolution and time inefficiency, often fail to capture spatial heterogeneity across large areas.

To address these limitations, this research developed a …

Measurement Of Forces In Standing Wave Ultrasonic Fields, Milan Rai

Electronic Theses and Dissertations

The acoustic radiation force provides the physical mechanism for the non-contact levitation and manipulation of particles in ultrasonic standing wave fields. This thesis presents a study on the measurement, simulation, and validation of acoustic radiation forces acting on spherical particles levitated in air. The motivation for this work is to provide high-precision measurements of acoustic radiation forces in trapping systems, which are of particular interest in biomedical manipulation, materials science, and contactless assembly.

The study employs a three-part methodology: theoretical analysis, experimental observation, and numerical simulation. Theoretically, the acoustic radiation force was derived from Gor’kov’s potential (valid for ka « …

Groundwater Age Estimates For The Mississippi River Valley Alluvial Aquifer And Comparisons With Hydrogeologic Heterogeneity, Michael Gratzer

Electronic Theses and Dissertations

Groundwater age is a useful tool for characterizing various aspects of groundwater availability. No aquifer-wide groundwater age characterization was completed for the Mississippi River Valley alluvial aquifer (MRVA) before this study. Using 3H, 14C, SF6, and 3Hetrit concentrations in groundwater samples from the MRVA and some underlying aquifers of the Mississippi embayment, this study estimated age distributions of samples with lumped parameter models (LPMs) in the U.S. Geological Survey (USGS) TracerLPM software and investigated the factors controlling groundwater age in the MRVA. To better understand how hydrogeologic heterogeneity affects groundwater age, each sample’s age distribution coefficient of variation [Cv(LPMAD)] was …

Fictional And Historical Narratives Of African American Soldiers Of Wwii, Abigail Rae Stewart

Honors Theses

This thesis examines the experiences of African American soldiers during World War II through the dual lenses of oral histories and fictionalized accounts, arguing that both are essential to fully understanding their multifaceted journeys at home and abroad. Oral histories provide direct, personal narratives from veterans themselves, capturing their voices, emotions, and reflections on the discrimination, camaraderie, and resilience that defined their wartime and postwar lives. These firsthand accounts offer invaluable insights into the structural realities of systemic racism within the military and society, as well as the personal sacrifices these soldiers made in the name of a country that …

Deciphering Mechanochemical Influences Of Emergent Actomyosin Crosstalk Using Qcm‑D, Emily M. Kerivan, Victoria N. Amari, William B. Weeks, Leigh H. Hardin, Lyle Tobin, Omayma Y. Al Azzam, Dana N. Reinemann

Faculty and Student Publications

Purpose: Cytoskeletal protein ensembles exhibit emergent mechanics where behavior in teams is not necessarily the sum of the components’ single molecule properties. In addition, filaments may act as force sensors that distribute feedback and influence motor protein behavior. To understand the design principles of such emergent mechanics, we developed an approach utilizing QCM-D to measure how actomyosin bundles respond mechanically to environmental variables that alter constituent myosin II motor behavior.

Methods: QCM-D is used for the first time to probe alterations in actin-myosin bundle viscoelasticity due to changes in skeletal myosin II concentration and motor nucleotide state. Actomyosin bundles were …

Collapse Of Pre-Covid-19 Differences In Performance In Online Vs. In-Person College Science Classes, And Continued Decline In Student Learning, Gregg R. Davidson, Hong Xiao, Kristin Davidson

Faculty and Student Publications

Abstract: Studies comparing student outcomes for online vs. in-person classes have reported mixed results, though with a majority finding that lower-performing students, on average, fare worse in online classes, attributed to the lack of built-in structure provided by in-person instruction. The online/in-person outcome disparity was normative for non-major geology classes at the University of Mississippi prior to COVID-19, but the difference disappeared in the years after 2020. Previously distinct trendlines of GPA-based predictions of earned-grade for online and in-person classes merged. Of particular concern, outcomes for in-person classes declined to match pre-COVID-19 online expectations, with lower-GPA students disproportionally impacted. Objective …
