Economic And Financial Analysis Of Rainwater Harvesting Pond: A Case Study At Morehead State University, Riley Q. Williams, Vijay Subramaniam, Amanda Skidmore

2023 Celebration of Student Scholarship - Poster Presentations

Rainwater harvesting (RWH) was primarily considered as a source for fresh water supply or a conservation practice for overcoming water shortages in drought prone areas. By retaining storm-water run-off for onsite use, harvesting systems reduce the runoff volumes and pollutant masses entering waterways. Some of the most interesting aspects of RWH are the methods of capture, storage, and the use of this natural resource at the place it occurs.

Collection Maintenance After Maintenance Lost: Making Meaning From The Rock Pile, Abbie Grzynkowicz, Zachary Strait, Miles Terry, Jen O'Keefe

2023 Celebration of Student Scholarship - Poster Presentations

The Geology Program has formal book, fossil, journal, map, mineral, and rock collections dating to the 1950’s. These specimens were donated by biological and physical sciences faculty prior to the 1960 hire of Dr. John Philley and greatly expanded upon by Drs. Philley, James Chaplin, Jules DuBar, and H.W. Straley III through the 1990’s. Prior to construction of the “C-wing” of Lappin Hall, the collections previously housed in laboratory classrooms in the path of the new corridor connecting the “B-wing” and “C-wing”, as well as those housed in the “A-wing” were boxed and stored in multiple temporary locations until new …

Universal Quality Control For Brewers, Taylen Hylton, Geoff Gearner

2023 Celebration of Student Scholarship - Poster Presentations

Beer, the product of fermentation that arguably changed the course of human civilization. Though the first brewing process dates back to ancient Mesopotamia, the modern method still presents a host of flaws. There are both many steps of fermentation and many opportunities for contamination. Most breweries will experience some form of spoilage in their lifetime. These invading microorganisms can alter turbidity, coloration, aroma, taste, and the overall quality of the product. This disruption is devastating for commerce. A centralized method of testing would help to eliminate spoiled products and prevent future infections. The following procedure utilizes a combination of polymerase …

Health And Wealth: Hidden Disparities In Eastern Kentucky, Macaila Blankenship, Geoff Gearner

2023 Celebration of Student Scholarship - Poster Presentations

Eastern Kentucky lags behind the rest of the state regarding proper health, while Kentucky as a whole is doing worse than national averages. Kentucky not only leads the United States in cancer mortality, but sees higher mortality from heart disease, injury, suicide, diabetes, and chronic obstructive pulmonary disease. The health crisis being observed can largely be attributed to high poverty rates throughout the Eastern half of the state. Considering the not-so-broad socioeconomic scale seen throughout much of Kentucky, it is more evident that health has a direct correlation to one’s wealth and resources. Along with being financially secure, those who …

Predicting The Reactions Of Cs2 With Group Iv And Group Vi Transition Metal Oxides, Marissa Blair, David A. Dixon, Zachary R. Lee

2023 Celebration of Student Scholarship - Poster Presentations

Building onto a recent serious of ab initio studies of various acid-gas reactions with metal oxide sorbents, electronic structure methods are being used to study the addition of CS₂ to Group IV (MO₂)ₙ and Group VI (MO₃)ₙ (n = 1, 2, 3) nanoclusters, beginning with the MO₂ and MO₃ monomers according to a “bottom-up” approach. The preliminary density functional theory (DFT) calculations in this study provide structures and vibrational frequency thermodynamic corrections for later expanding upon by way of single point correlated molecular-orbital theory (MO) calculations, mainly CCSD(T) and MP2 to study the structures and energies which could arise from …

Repressor Of The Sos Response Mechanism In Acinetobacter Baumannii Requires Helix-Formation And Dimerization For Its Dna-Binding Ability, Belinda Candra, Deborah Cook, Jenelle Hare

2023 Celebration of Student Scholarship - Poster Presentations

After DNA damage, the multi-drug resistant pathogen Acinetobacter baumannii activates its SOS response, possibly allowing mutagenesis to occur by inducing multiple errorprone polymerases. A. baumannii uses the non-canonical repressor protein UmuDAb to repress operons of these polymerases. It has an N-terminal domain (NTD) with 2 helices (HTH1 & HTH2) whose sequences are needed for repression1. Like other bacterial SOS repressors such as LexA, UmuDAb dimerizes. BACTH analyses2 showed that UmuDAb forms dimers via its LexA-like G124 residue and UmuD-like N100 residue (UmuD is a component of an error-prone polymerase). However, N100 is not needed if the C termini are free. …

Biomimicry In Solar Energy Applications, Terrin Cramer, Yicheng Kang, Ryan Ogino

Electrical and Computer Engineering Senior Theses

While solar power is one of the leading renewable energy sources today, current solar farms produce an amount of byproduct heat that is contributing to rising global temperatures and the deaths of many birds. Furthermore, solar panels that use water as a coolant through a sprinkler system use up a great amount of water that could be allocated somewhere else. Our project seeks to address both of these issues through a biomimetic design. Drawing inspiration from the ghost plant, our proposed solar panel cooling system is expected to reduce the amount of byproduct heat produced by panels, increase the overall …

Colorimetric Redox Reactions To Determine Base Composition In Unknown Monomeric Dna Samples, James T. Dials, Mara J. Stout, Elizabeth M. Thomas

2023 Celebration of Student Scholarship - Poster Presentations

Deoxyribonucleic acid (DNA) codes for proteins using a unique order of four major nitrogenous bases adenine, thymine, cytosine, and guanine. In several biological applications, such as the determination of DNA stability, production of biologic based drugs, and even taxonomic reorganization of species, it becomes necessary to understand the relative amounts of each nucleotide in a DNA sample, regardless of their sequence. However, most assays used to determine base composition use expensive equipment, harsh chemicals, and advanced computer software. In addition, the determination of base composition is an important educational tool in undergraduate laboratories, but these limitations are infeasible for many …

Feasibility Of Sewer Overflow Treatment Using Chemical Oxidation After Rapid Solids Removal, Paige Peters

Dissertations (1934 -)

Sewer overflows discharge 850 billion gallons of untreated sewage into U.S. lakes and rivers every year during high-intensity precipitation events. Common approaches include storage tanks or rapid solids removal followed by chlorine disinfection. These approaches can be capital intensive and only achieve partial treatment. A decentralized, end-of-pipe sewer overflow treatment system would eliminate detrimental overflow effects while handling highly variable flow and pollutant loading. Specifically, the rapid reaction rate of chemical oxidation can achieve soluble organics removal and disinfection of chlorine-resistant pathogens in a small footprint. To address the overflow issue, an advanced high-rate treatment system (AH-RTS) was developed and …

Electrocoagulation For Treatment Of Disinfection Byproducts, Organic Matter, And Per-And Polyfluoroalykl Substances., Donald Rockwood Ryan

Dissertations (1934 -)

Technologies are needed to treat contaminants such as disinfection byproducts (DBPs), trace organic compounds (TOrCs), and per- and polyfluoroalkyl substances (PFAS) in water to improve consumer safety and mitigate chronic risk. This dissertation focused on evaluating electrocoagulation (EC) and hydrogen peroxide (H2O2)-enhanced EC (peroxi-electrocoagulation; EC:H2O2) for treatment of these contaminants. The impacts of source water quality (such as natural organic matter [NOM]) on overall performance was assessed and the non-destructive and destructive pathways involved in treatment were evaluated. The first objective focused on EC performance for mitigating the formation of regulated DBPs in water to better substantiate EC’s performance relative …

Method: We introduce a new algorithm: SharpRazor, to detect hair and ruler marks and remove them from the image. Our multiple-filter approach detects hairs of varying widths within varying backgrounds, while avoiding detection of vessels and bubbles. The proposed algorithm utilizes grayscale plane modification, hair enhancement, segmentation using tri-directional …

Predicting The Mechanism And Products Of Cs2 Capture By Nh3 - An Exemplar Benchmark Study, Shelbie A. Black, David A. Dixon, Zachary R. Lee

2023 Celebration of Student Scholarship - Poster Presentations

Carbon disulfide is a toxic gas emitted from industrial plants and a common greenhouse gas. Acute poisonings from carbon disulfide are rare, but recurring exposure to low doses can have long term health effects. Currently, there are two approaches being considered for the removal of acid gas pollutants: (1) sequester these gases from the atmosphere or (2) remove these gases directly upon combustion (post-combustion). Potential energy surfaces (PES) for a series of CS2 capture reactions by NH3 in the presence H2O were calculated at the MP2/a(D+d) evel in the gas phase. G3(MP2) and FPD calculations are in progress. Extensive thermodynamic …

Estimating Crop Stomatal Conductance Through High-Throughput Plant Phenotyping, Junxiao Zhang

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

During photosynthesis and transpiration, crops exchange carbon dioxide and water with the atmosphere through stomata. When a crop experiences water stress, stomata are closed to reducing water loss. However, the closing of stomata also negatively affects the photosynthetic efficiency of the crop and leads to lower yields. Stomatal conductance (gs) quantifies the degree of stomatal opening and closing by using the rate of gas exchange between the crop and the atmosphere, which helps to understand the water status of the crop for better irrigation management. Unfortunately, gs measurement typically requires contact measuring instruments and manual collection in the field, which …

This study aims (1) to characterize the physical and biochemical traits of wheat and corn plants using RGB and hyperspectral imaging in the greenhouse, and (2) to estimate leaf nitrogen (N), phosphorus (P), and potassium (K) content using hyperspectral imaging and an analytical spectral device (ASD spectrometer) and compare the …

Impact Resistance Of Hybrid Metal-Organic Frameworks/Carbon Fibers Composites, Derek Isaac Espinosa Ramirez

Doctoral Dissertations and Master's Theses

The increase in the use of carbon fiber-reinforced polymers (CFRPs) composites in the aerospace industry generated the need of improving the properties and capabilities of these composites by adding nano-reinforcements to the carbon fibers, also called hybrid fiber reinforced polymer composites. In this study, the energy absorption due to impact at low speed will be tested and simulated in four configurations of CFRPs utilizing the same [0/90]_S layout throughout them.

The carbon fiber configurations used during this study are de-sized, acid-activated, metal-organic frameworks (MOF), and carbon nanotubes (CNTs). Nickel (II) Nitrate, Methylimidazole, and Methanol were used to grow the …

Detecting Physiological Concentrations Of Alzheimer’S Associated Amyloid-Β Protein Utilizing A Cell-Based Response, Brittany Elizabeth Watson

Theses and Dissertations

Alzheimer’s disease (AD) is characterized symptoms of cognitive impairment resulting from blood-brain barrier (BBB) breakdown and neuronal cell death. AD is associated with aggregated amyloid-β (Aβ) plaques deposited around brain vasculature and within the brain. Changes in the brain occur up to 20 years before symptoms arise; however, there is currently no pre-symptomatic detection method available for AD. An intact BBB requires tight junction proteins (TJs) that render relatively high transendothelial electrical resistance (TEER). AD-associated breakdown of the BBB correlates with vascular Aβ deposition, suggesting that aggregated, pathological Aβ can modulate TEER. We explore leveraging this cellular response for early …

Utilizing The System Engineering Trade Study Analysis Method To Analyze Patient Aeromedical Evacuation, Sara Shaghaghi, Jeremy M. Slagley, Michael E. Miller, Gaiven Varshney

Faculty Publications

The US Air Force has gone through many aeromedical patient isolation transport system designs. The first designs were developed in response to the Ebola outbreak in 2014 and, more recently, the COVID-19 pandemic. The trade study analysis part of the system engineering design method was used to analyze the historic and current aeromedical patient contamination control transport systems. A trade study is a process that evaluates alternatives based upon various “-ilities”, such as reconfigurability, flexibility, durability, cost, and more, and performs a systematic analysis to aid designers in producing a ‘good’ design alternative given the large set of possible solutions. …

An Inexpensive, Reproducible Method To Quantify Activated Sludge Foaming Potential: Validation Through Lab-Scale Studies And Year-Long Full-Scale Sampling Campaign, Grace K. Scarim, Emily Lou Lamartina, Kaushik Venkiteshwaran, Daniel Zitomer, Ryan J. Newton, Patrick J. Mcnamara

Civil and Environmental Engineering Faculty Research and Publications

Activated sludge is a conventional treatment process for biochemical oxygen demand (BOD) and total suspended solids (TSS) removal at water resource recovery facilities (WRRFs). Foaming events are a common operational issue in activated sludge and can lead to decreased treatment efficiency, maintenance issues, and potential environmental health risks. Stable foaming events are caused by biological and chemical drivers (i.e., microbes and surfactants) during the aeration process. However, foaming events are difficult to predict and quantify. We present an inexpensive and easy-to-use method that can be applied at WRRFs to quantify foaming potential. Subsequently, the method was applied over a year-long …

Urban Water Quality: Socio-Economic Distribution Of Stream Degradation, And The Influence Of Climate On Bmp Performance, Isabelle Horvath

Dissertations (1934 -)

Urban water quality impairments have long burdened urban aquatic ecosystems in a phenomenon termed “urban stream syndrome”. The symptoms of this “syndrome” include physical changes in stream morphology and water level, biologically stressed environments, and perturbations in ecosystem processes. Despite years of research and costly investments in restoration and rehabilitation, urban waterways are still plagued by degradation. Improvement in urban water quality will require multi-faceted efforts, including progress on 2 key fronts 1) increased understanding of current impairments, and 2) increased knowledge about urban stormwater infrastructure like best management practices (BMPs). Towards both topics, engineers have quantified the influence of …
