Nuclear Power Plant In Las Vegas, Ryan W. Murray
Undergraduate Research Symposium Posters
This research focuses on the impact of a “Nuclear Power Plant in Las Vegas” or ‘NPP in LV’ for short. Nuclear power is clean, has no greenhouse gas emissions, and has a moderate cost of kilowatt hours. Las Vegas, or more specifically Clark County uses Gas power plants to produce a majority of their electricity. My project will show what a nuclear plant could do if built in the city of Las Vegas. What is a Nuclear power plant? The EIA’s definition is “A nuclear power plant uses the heat that a nuclear reactor produces to turn water into steam, …

Poliovirus Detection In Las Vegas Wastewater, Sage Boss, Hayley Baker, Ching-Lan Chang
Undergraduate Research Symposium Posters
Wastewater surveillance for poliovirus is a useful tool for spatial surveillance and evaluation of immunization efficacy. Polio testing in wastewater has been conducted since the 1980s in Finland and Israel, and the virus was recently discovered in New York. With increasing concern regarding the vaccination of children against the virus, there has been worry that polio cases could once again present themselves in the Las Vegas Valley. By testing for the virus in wastewater, we can monitor any new cases or outbreaks that occur and inform authorities as to the location and viral count. The wastewater samples were collected at …
The Analysis Of Radio And X-Ray Energetics Of Fast Radio Bursts, Emily Huerta
The Analysis Of Radio And X-Ray Energetics Of Fast Radio Bursts, Emily Huerta
Undergraduate Research Symposium Posters
Here, we analyze the graphs and figures presented in Laha et al. (2022) and compare their slopes to our figures. Laha et al. (2022) includes two graphs, one that shows a comparison between radio fluence vs. x-ray fluence and radio energy vs. x-ray energy. In these graphs, the slopes are anywhere from 3.3e-14 to 2e-5, which are much less than unity. Our figures are consistent with these values, also providing slopes anywhere between the same range. Strong limits on this ratio between radio and x-ray energetics can either support the magnetar progenitor model, or completely dismiss it. Since we found …
The Global Effects Of Climate Change: Detrimental Impacts On The Environment, Ecosystem, Coral Reefs, Human Health/Well-Being, And Global Economy, Lucky Heng
Undergraduate Research Symposium Posters
Despite criticism, scientists have been continuing to find more evidence to prove that the threats on the coral reefs around the world are real. The impact of rising climate temperature, pollution, ocean acidification, etc. has been leading to increasing amounts of mass bleaching and a massive decline in coral reefs in past decades. This research study utilizes a systematic literature review and secondary research to collect, analyze and provide evidence that climate change impacts the ecosystem, and marine life (coral reefs) species on the planet. By addressing the impact of climate change and its significance on the ecosystem and global …
Trapping And Cooling Of Ca+ For Cold Ion-Radical Collisions, Bernardo Gutierrez
Trapping And Cooling Of Ca+ For Cold Ion-Radical Collisions, Bernardo Gutierrez
Undergraduate Research Symposium Posters
Free radicals are molecules that contain an unpaired valence electron which induces high reactivity. Ion radical reactions are typically exothermic and have low (or zero) activation energy. It is for these reasons that ion-radical reactions are believed to dominate in interstellar clouds where temperatures hover around 3-10K. State-to-state measurements require precision control of both reactants.

3-D Visualizations Of Terrestial Exoplanet Interiors Generated With Magrathea In Blender, Tristan Benally, David Rice
Undergraduate Research Symposium Posters
There has been significant progress in simulating exoplanet interiors in the past decade. With the discovery of the TRAPPIST-1 system in the last few years, there have been many publications presenting models to best characterize specific aspects of exoplanets in study. However, with more parameters and considerations for different characteristics of an exoplanet there will be a need to represent many findings into a comprehensive model in the future. We extend the capabilities of MAGRATHEA from a planet interior solver to start incorporating multi-faceted functions starting with generating 3-D terrestrial planetary visualizations using a 3-D open-source computer graphic software called …
Examining Cultural And Chemical Treatments To Fusarium Bulb Rot In Onions, Tim Miller
Examining Cultural And Chemical Treatments To Fusarium Bulb Rot In Onions, Tim Miller
Fall Student Research Symposium 2022
Onions are grown in 1,500 acres in northern Utah and are a large part of growers' income. In the fall of 2021, 30% of a grower's onion yield was affected by Fusarium bulb rot (caused by a fungus known as Fusarium proliferatum) and the onions were unmarketable. The literature surrounding this pathogen is sparse and losses of this magnitude could cause growers to lose between six and seven thousand dollars per acre. Samples of the fungus were plated onto potato dextrose agar at half strength and maintained fresh throughout the winter. In vitro experiments were performed with various fungicides at …

Assessing The Impact Of Storage Time And Shape Of The Block On The Slicability Of Commercial Cheddar Cheese, Nathan Pace
Assessing The Impact Of Storage Time And Shape Of The Block On The Slicability Of Commercial Cheddar Cheese, Nathan Pace
Fall Student Research Symposium 2022
Cheddar cheese is one of the world's most popular cheeses and is consumed in blocks and slices. The slicability of cheddar cheese can depend on textural and rheological properties. Understanding these characteristics can enhance desirability and reduce material loss occurring during slicing. In this study, we focused on four main parameters: slice thickness, cheese shape, storage period, and cheese type. Four thicknesses (0.5, 1.0, 1.5, and 2.0 mm) and two shapes (triangular and square) of mild, medium, sharp, and extra sharp were selected. Cheeses were purchased from Walmart and the Utah State University creamery. At first, cheese blocks were cut …
Why America Should Switch To Nuclear Energy As Its Primary Power Source, William Fike
Why America Should Switch To Nuclear Energy As Its Primary Power Source, William Fike
Fall Student Research Symposium 2022
While nuclear waste and public fear hurt the image of nuclear energy, I believe that nuclear energy should be used instead of alternative power sources because it is safe, carbon-free, and more fuel efficient than alternative energy sources. Nuclear power is the process of using uranium 235 to make energy. Nuclear energy is a very clean and safe energy producer. My target audience would be someone who does not know a lot about nuclear power. Or they are possibly scared because of past nuclear disasters. My goal in this poster is to convince you that nuclear power is safe and …

Electron Yield Measurements Of Highly Insulating Granular Samples Related To Charging Of Dusty Plasmas, Heather Allen
Fall Student Research Symposium 2022
Reliable electron yield (EY) measurements of highly insulating granular particles have long been considered too difficult to collect due the many experimental complexities that arise from the nature of the granular materials. This has led to a critical knowledge gap for both engineering strategies and basic science issues essential for myriad important space applications. This talk will emphasize the preliminary EY measurements of highly insulting granular samples we have collected, including a range of samples with typical particle size ranging from ~1 μm to ~100 μm, samples with cubical, spherical and highly angular particle shapes, studies of highly angular Al2O3 …

Fall Student Research Symposium 2022
Investigating the Color-Changing Properties of Poly-Phenyl Sulfide Dallen DeWaal, Megan Loveland DeWaal, Heather Allen, JR DennisonMaterials Physics Group, Physics Department, Utah State UniversityAbstractWhile preparing samples of FortronTM PPS (poly-phenyl sulfide) for spacecraft charging testing, it was discovered that the polymeric dielectric material exhibits color-changing properties from mechanical forces while shearing and bending. Given enough time, PPS reverts from blue-green back to its original tan color. PPS samples were characterized by the magnitude of color change and recovery time. PPS samples were subjected to multiple tests to discover which forms of energy input activate the color change, and which (if any) …
The Effect Of The Plant-Based Diet On Athletes And Its Limitations, Dylan Hill
The Effect Of The Plant-Based Diet On Athletes And Its Limitations, Dylan Hill
Fall Student Research Symposium 2022
In this study, I was hoping to learn more about the differences between the omnivore diet and plant-based diet in relation to the effects on an athlete. Research was conducted using library and internet resources to locate both primary and secondary research. For this study, personal accounts and experiences of athletes who had experimented with a plant based diet were examined. Research showed that although a very enticing option for a healthy diet for athletes, the plant-based diet is just as effective as a balanced omnivore diet but much more difficult to do properly and is much less accessible to …
Effects Of Exposure To Atmospheric Humidity On Breakdown Field Strength Measurements Of Polymers, Megan Loveland Dewaal
Effects Of Exposure To Atmospheric Humidity On Breakdown Field Strength Measurements Of Polymers, Megan Loveland Dewaal
Fall Student Research Symposium 2022
This study investigates the effects of absorbed water introduced via exposure to atmospheric humidity on electrostatic breakdown field strength measurements of polymers. Conducting breakdown tests under sample conditions appropriate for different applications is essential. If the breakdown field strength is overestimated for an application, an insulator may be used inappropriately in high electric fields where they are more likely to break down. Comparisons are made between: sets of pristine samples, samples that underwent a thorough vacuum bake out to evaporate absorbed water, and samples subject to subsequent incremental prolonged atmospheric exposure. These investigated the effects of absorbed water and determined …
Light Scattering From Periodic Conducting Nanostructures, Wesley Mills
Light Scattering From Periodic Conducting Nanostructures, Wesley Mills
Fall Student Research Symposium 2022
Carbon nanotube (CNT) forests are roughly vertically aligned carbon tubes with a diameter of a few nanometers, and a height of hundreds of micrometers. CNT forests of proper densities and heights can be excellent absorbers of visible light, so a lot of interest has been generated in their application in optical calibration, energy conversion, antireflection, and radiometry. Unfortunately, reflectance from CNTs rises quickly above the mid-infrared range, limiting their present use. Improving a CNT-based broadband absorber requires understanding why the forests have almost zero visible-light reflectance, as well as a strategy to extend that low reflectance into longer wavelengths. Since …
How Does Perceived Human Instability Affect One's Own Stability?, Madi Braunersrither
How Does Perceived Human Instability Affect One's Own Stability?, Madi Braunersrither
Fall Student Research Symposium 2022
Participants were prompted to evaluate the stability of pictured human postures while standing on a force plate. We measured irregularity by analyzing the presence of patterns in the sequential center of pressure values. To measure the presence of patterns, sample entropy, a time series statistic, was developed and we utilized it on the force plate data. Does one's own stability change when viewing a posture deemed unstable? Is Sample Entropy (SampEn) an effective tool to determine stability? This relationship could have implications for modeling the progression of motor skills, understanding human development, and the design of environments for rehabilitation.
The Stigma Against Elderly Drivers And An Analysis Of The Effects Of Age On Driving Ability, Alexander Lee
The Stigma Against Elderly Drivers And An Analysis Of The Effects Of Age On Driving Ability, Alexander Lee
Fall Student Research Symposium 2022
Elderly drivers are not as big of a danger on the road as the general population believes. This was preliminary research into the significance of elderly drivers on the road and the statistical data on whether they are a hazard on the road. They are among the minority of people that are in car accidents and most elderly people still on the road are more experienced and drive safer to compensate for ailments they may experience from their age. Elderly that can not drive safely or can pose a hazard on the road usually remove themselves from driving or are …
