Frequency Of Genetic Variants At The Mc1r Locus In A Student Population, Emmalea K. Dowdy, Grace C. Stubblefield, David K. Peyton

2022 Celebration of Student Scholarship - Poster Presentations

The Melanocortin-1 Receptor gene (MC1R) encodes a protein that is associated with pigmentation in vertebrate animals. An extraordinary number of variations in this gene have arisen over time due to the importance of pigmentation in camouflage, photosensitivity, vitamin D production, and other evolutionary factors. Variations in the MC1R gene sequence became important to survival as humans migrated out of Africa and into cooler climates with less sun exposure, where lighter skin pigmentation (and therefore more vitamin D production) was key to survival. These genetic variations (alleles) continue to exist in modern humans. Recent research into the MC1R gene variations shows …

Great (Soft) Power Competition: Us And Chinese Efforts In Global Health Engagement, Michael W. Wissemann

The US Army War College Quarterly: Parameters

Global health engagement, an underutilized strategy rooted in the strengths of soft power persuasion, can lead to more military-to-military cooperation training, help establish relationships that can be relied on when crises develop, stabilize fragile states, and deny violent extremist organizations space for recruiting and operations. Examining Chinese efforts worldwide to curry favor and influence and the challenges posed by the COVID-19 pandemic, this article shows health as a medium is a very compelling and advantageous whole-of-government approach to national security policy concerns.

Optimization Of Vaccine Supply Chains In Low- And Middle-Income Countries Utilizing Drones, Maximilian Kolter

Graduate Theses and Dissertations

Despite tremendous efforts from governments and humanitarian organizations, millions of children in low- and low-middle-income countries (LICs and LMICs) are still excluded from the benefits of immunization. The vaccine distribution in LICs and LMICs is challenging for several reasons, such as limited cold chain capacities, vaccine wastage, uncertain demand, and lack of access to immunization services. A promising avenue to address these issues is the utilization of drones for vaccine delivery. Drones can fly at high speed on direct paths and could enable on-demand deliveries to mitigate limited storage capacities. Further, their independence of road networks could allow them reaching …

Cs-NPs contain positive charges that can interact …

Understanding The Effect Of Adaptive Mutations On The Three-Dimensional Structure Of Rna, Justin Cook

Undergraduate Research and Scholarship Symposium

Single-nucleotide polymorphisms (SNPs) are variations in the genome where one base pair can differ between individuals.¹ SNPs occur throughout the genome and can correlate to a disease-state if they occur in a functional region of DNA.¹According to the central dogma of molecular biology, any variation in the DNA sequence will have a direct effect on the RNA sequence and will potentially alter the identity or conformation of a protein product. A single RNA molecule, due to intramolecular base pairing, can acquire a plethora of 3-D conformations that are described by its structural ensemble. One SNP, rs12477830, which …

Effects Of The Coronavirus Pandemic On United States Custom Grain And Forage Harvesting’S Labor Supply And The 2020 Harvest, Dalton Black, Jason Holcomb

2021 Celebration of Student Scholarship - Oral Presentations

The global coronavirus pandemic disrupted migratory labor around the world, including foreign seasonal labor that travels to the United States to work in the mobile custom grain and forage harvesting industry that operates primarily in Great Plains states. The pandemic caused the United States to implement bans on travel from labor sending countries, and to delay the processing of the H-2A and J-1 visa nonimmigrant visas used by foreign custom grain and forage harvesting employees to enter the US. Many transnational workers were thus delayed or prevented from reporting for jobs that require training before harvest begins in April or …
