Relationships Between Cognitive And Physical Performance And Readiness In Military Populations, Lina Ochoa

Theses and Dissertations--Rehabilitation Sciences

Military missions and operations expose warfighters to stressful and demanding situations and dynamic environments. These situations and environments require that warfighters have optimal performance in several dimensions of human performance, such as cognitive and physical performance. Military readiness is the potential these military units or personnel have to successfully deploy and sustain assigned operational missions worldwide. Military readiness is essential for increased physical and cognitive performance, ensuring augmented individual and unit effectiveness, lethality, and national security. The primary challenge is understanding and finding ways to measure and assess the cognitive, behavioral, and physical performance effects of complex and challenging environments …

Neuroimmune Response And Neurodegeneration In Adolescent Rats Following Binge Alcohol Exposure, Catherine Van Doorn

Theses and Dissertations--Pharmacy

Studies of adolescent drinking show a distinct prevalence of binge drinking, including at extreme levels, and this type of drinking has been identified as increasing risk of developing an Alcohol Use Disorder (AUD). Additionally, females suffer greater levels of harm from binge drinking and AUD and in an abbreviated timeline compared to males. Neuroimmune reactivity, specifically with microglial reactivity following binge drinking, may influence the sex differences seen in negative alcohol-related health disparities.

The first set of experiments sought to examine a marker of microglial reactivity, TSPO, in adolescent females and males and found the sexes displayed different temporal and …

Sustainable Additive Manufacturing Of Polysulfone Membranes For Liquid Separations, Brian Leonard, Harrison Loh, David Lu, Ebuka A. Ogbuoji, Isabel Escobar, Konstantinos Sierros, Oishi Sanyal

UK CARES Faculty Publications

Membranes serve as important components for modern manufacturing and purification processes but are conventionally associated with excessive solvent usage. Here, for the first time, a procedure for fabricating large area polysulfone membranes is demonstrated via the combination of direct ink writing (DIW) with non-solvent induced phase inversion (NIPS). The superior control and precision of this process allows for complete utilization of the polymer dope solution during membrane fabrication, thus enabling a significant reduction in material usage. Compared to doctor blade fabrication, a 63% reduction in dope solution volume was achieved using the DIW technique for fabricating similarly sized membranes. Cross …

Temperature-Dependent Stress–Strain Behavior Of Amorphous And Crystalline P3ht, Kehinde H. Fagbohungbe, Connor P. Callaway, Chad Risko

UK CARES Faculty Publications

The scalable commercialization of organic electronics wherein p-conjugated polymers serve as the semiconductors hinges on precise control of the material electronic, redox, optical, and mechanical properties, which are each highly influenced by local and long-range morphology. Here, we undertake atomistic molecular dynamics (MD) simulations at three temperatures (150 K, 300 K, and 400 K) to assess the morphological and mechanical response of bulk poly(3-hexylthiophene) (P3HT), a representative homopolymer of interest as an organic semiconductor (OS). As P3HT is a semicrystalline polymer, we characterize mechanical properties for both amorphous and crystalline P3HT models to derive insights into structure–property relationships, including Young’s …

A Case Study In Program Evaluation, Alyssa Osborne

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

As a result of a Methicillin-Resistant Staphylococcus Aureus (MRSA) outbreak at a local high school, the Lexington Fayette County Health Department (LFCHD) has been tasked with developing a program to ensure timely reporting of actions taken in the event of a MRSA outbreak or disease outbreak of similar nature (1). This program evaluation is guided by the CDC’s 6-step program evaluation framework (2), which was used to inform this assessment.

Evaluation Of Public Radon Messaging In Kentucky As Compared To Three Other States, Abigail Knapp

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

Radon poses a large health risk to those exposed to it, as it is an invisible, odorless, carcinogenic gas. Kentucky has high ambient levels of radon, but public awareness remains low as tobacco has been publicized as the main cause of lung cancer. As Kentucky has the highest incidence of lung and bronchial cancers in the United States, we aimed to examine the state’s health department radon page to see if it has sufficient information to warn residents about radon and provide resources. We reviewed the current Kentucky public messaging, radon rates, testing rates, and legislation compared to Ohio, Washington, …
