Chemogenetic Induction of Sleep via Targeted Manipulation of Sleep Regulatory Circuits of the Brain
(2026-07-31)
In the U.S. alone, more than fifty million people suffer from chronic sleep disorders and sleep deprivation. Although sleep aids are commonly used as a remedy, they generally do not replicate natural sleep. Manipulation ...
Factors Influencing Woodworking Knowledge, Safety Preparation, and Instructional Confidence Among Georgia SBAE Agricultural Mechanics Instructors
(2026-07-31)
Woodworking instruction has historically served as an important component of School-Based Agricultural Education (SBAE) agricultural mechanics programs; however, limited research has examined how agricultural mechanics ...
Data-Driven Models for Anisotropic Pairwise Interactions using Limited Sampling
(2026-07-31)
The interaction of two particles with shape anisotropy depends not only on their separation but also on their relative orientation. Such interactions are known to lead to interesting collective behavior such as self-assembly ...
Postharvest Evaluation of Blueberry Cultivars for Fruit Quality and Sensory Characteristics
(2026-07-31)
Blueberry (Vaccinium spp.) production and consumption are a continuously growing market with United States (U.S.) fresh market exceeding $1.02 billion. Rabbiteye (V. virgatum; RE) and southern highbush (V. corymbosum; SHB) ...
Allelopathic Potential and Weed Control Dynamics of Winter Cover Crops in Southeastern United States Corn Production
(2026-07-30)
Corn production is limited by multiple factors, including weeds. Sole dependency on herbicides has led to multiple problems. Therefore, integrated weed management is crucial to reduce sole dependency on herbicide. Cover ...
Improvement of a Three-Dimensional Hydrodynamic Model Downstream of a Lock and Dam Using ADCP-Derived Bathymetry and Velocity Field Observations
(2026-07-30)
Locks and dams alter downstream hydraulics by changing channel geometry, flow distribution, and velocity structure. This study improved an EFDC+ three-dimensional hydrodynamic model downstream of Claiborne Lock and Dam on ...
Evaluation of interseeded forbs and pasture composition in Alabama cool-season grazing systems
(2026-07-30)
Diversification of Southeastern pasture systems with cool-season annual forbs has been proposed as a low-input pathway toward improved sward composition and reduced enteric methane emissions through plant secondary metabolite ...
Experimental Characterization of Rotational Stiffness and Moment Capacity in Plain-Embedded Steel H-Pile to Bent Cap Connections
(2026-07-30)
Steel H-pile to concrete bent cap connections relying on plain pile embedment are standard in short-span highway bridges across the United States. Current practice treats these connections as pinned or fixed, yet actual ...
Nano-Enhanced Electrokinetic Conditioning of Expansive Soils
(2026-07-30)
This study presents a combined experimental and numerical investigation into the stabilization of expansive soils using magnesium oxide (MgO) nanoparticles and electrokinetic (EK) treatment. The research was conducted in ...
Evaluating best management practices for pollinator plantings in the southeastern USA
(2026-07-30)
Recent bee declines highlight the importance of bee conservation efforts,
including planting wildflower meadows for pollinators. Pollinator plantings require
management to maintain a high abundance and diversity of ...
Compatible Contradictions: The Deep South’s Metropolitan Community Church’s Role in Gay Liberation
(2026-07-30)
This thesis examines the impact of the Metropolitan Community Church on the gay communities of Georgia and Alabama through the Gay Liberation Movement of the 1970s and into the rise of the AIDS epidemic of the 1980s. The ...
Deep Neural Network-Based Controllers with Guaranteed Exponential Convergence: A Lyapunov- and Concurrent Learning-Based Approach
(2026-07-30)
With the increase in computational power, there have been significant developments in deep
neural network (DNN)-based control approaches due their function approximation property. DNNs
are capable of approximating ...
Statewide Herbicide Resistance Screening and AI-Based Identification of Horseweed (Erigeron canadensis) in Alabama
(2026-07-29)
This thesis evaluated potential herbicide resistance in Alabama horseweed (Erigeron canadensis L.) populations and compared two digital detection approaches for horseweed identification using hyperspectral imagery. The ...
Design and Development of an Integrated In-Field Agricultural Robot for Terrain-Adaptive Mobility, Navigation, and Plant Phenotyping
(2026-07-29)
Reliable in-field plant phenotyping requires a robotic platform capable of stable
terrain mobility, controlled motion, accurate navigation, synchronized sensing, and
consistent crop measurement under uneven ground, ...
Effects of Fertigation Practices on Postharvest Quality and Microbial Safety of Microgreens
(2026-07-29)
Microgreens are young edible plants harvested at the cotyledon or first true leaf stage. They are valued for their high nutritional content, vibrant color, unique texture, and rapid growth cycle. As demand increases, ...
Multiscale Modeling and Assessment of Forest Carbon Stocks and Drivers of Carbon Dynamics in The Southeastern United States
(2026-07-29)
