Photoresponsive behavior of SPEEK/Cellulose films for oxygen sensing.
(2023-12-04)
Illumination of sulfonated poly(ether etherketone) (SPEEK) and cellulose films by 350nm photons resulted in an efficient redox system. The illuminated films resulted in radicals of SPEEK (SPEEKH•) which in the presence of ...
Essays in Agricultural and Food Policy: Impact of Crop Insurance on Fertilizer Use, Willingness to Pay a Premium on Beef, and Estimating the Demand for Carbonated Sweetened Beverage
(2023-12-04)
In recent years, empirical economic research has witnessed significant advancements. Simple linear regressions have evolved into different applied econometrics toolkits, which cover methods such as difference-in-difference ...
Aerodynamic loads and flow structures on a simultaneously rotating and pitching flat plate
(2023-12-04)
Unsteady flow separation and leading-edge vortices (LEV) profoundly impact the aerodynamics of insect wings, helicopter rotor blades, and similar systems. The dynamics of such systems depend on wing pitch rate and pivot ...
Evaluating the effects of soil tillage on ground nesting bees in the southeastern United States
(2023-12-04)
Pollination by native bees is an economically and ecologically valuable service, necessary in both agricultural and natural landscapes. The majority of bee species nest below ground, an aspect of their biology that raises ...
Resilience Across Subgroups of Posttraumatic Stress Disorder and Alcohol Misuse in the Military: A Latent Profile Analysis
(2023-12-04)
Veterans and active-duty service members (ADSM) are at an elevated risk for posttraumatic stress disorder (PTSD) and alcohol use misuse. Research indicates patterns of PTSD symptoms and alcohol use are highly heterogeneous, ...
Photodissociation dynamics of vibrationally excited hydrogen molecules examined with reaction microscopy in kinematically complete VUV + NIR experiments
(2023-12-04)
Using the Cold Target Recoil Ion Momentum Spectroscopy (COLTRIMS) technique, we investigated the dissociation of vibrationally excited H₂ and D₂ molecules after two-color vacuum ultraviolet (VUV) + near-infrared (NIR) ...
An Approach to Incorporate Generative Artificial Intelligence as a Means to Include Biomimicry within Industrial Design
(2023-12-04)
Biomimicry is most commonly defined as “innovation inspired by nature.” Biomimicry has the potential to make industrial design more sustainable, but has yet to be fully realized within the industrial design process and ...
Transmission-Type Impedance Probes for Use in Complex Plasmas
(2023-12-04)
Impedance probes measure electron density (ne ) and electron temperature (Te) by interpreting frequency-dependent transmission or reflection spectra (S21 or S11) of radiofrequency (RF) signals of low power (10−5 W). This ...
Veterans, Military Culture, and the Therapeutic Alliance
(2023-12-04)
Understanding how military culture influences the therapeutic alliance is vital to ensuring competent and ethical care for the veteran population. A qualitative analysis incorporating a social constructionist framework, ...
Evolution and Speciation in North American Toads
(2023-12-04)
Understanding speciation, the evolutionary process by which new species evolve, is a central goal of evolutionary biology. Yet many important questions regarding this process remain unanswered. In this dissertation, I ...
Using AI Models to Understand the Impact of COVID-19 in the Context of Long COVID and Food Delivery Operations
(2023-12-01)
Long COVID is unlike the usual diseases with well-defined symptoms or any medical test parameters. According to the CDC (Centers for Disease Control and Prevention), Long COVID is broadly defined as signs, symptoms, and ...
Robust Rank-based Metric for Evaluating Text Summarization
(2023-12-01)
Since information is growing exponentially, it is more important than ever to find effective ways to summarize text in the information age we live in. Automated text summarization systems are designed to make this process ...
On Translative Packing Densities in $E^2$ and $E^3$
(2023-12-01)
The theory of packing and covering is an essential part of discrete geometry. In this dissertation we focus on and contribute to the knowledge on the densities of translative and lattice packings in $E^{2}$ and ...
Telomeres dynamics across early life of the Cuban Brown Anole (Anolis sagrei)
(2023-12-01)
Telomere length is a key biomarker for cellular senescence and organismal survival. However, relatively little research has been conducted on the dynamics of telomeres in early life, particularly in reptiles. Through the ...
