Urban Ecology Of Birds In Mexico City, E. Elias Johnson, Byron J. Adams, Jerald B. Johnson, J. Jaime Zuniga-Vega Mar 2023

Urban Ecology Of Birds In Mexico City, E. Elias Johnson, Byron J. Adams, Jerald B. Johnson, J. Jaime Zuniga-Vega

Library/Life Sciences Undergraduate Poster Competition 2023

How organisms persist under extreme conditions has received a lot attention in ecology. Some extreme environments are natural and pristine (e.g., Antarctica or the Atacama Desert), while others are highly impacted by humans (e.g., large cities). Unfortunately, we know little about the ecology of species that live in urban environments relative to those in pristine environments.

Mystifying Mimics: The Influence Of Distribution On Mimicry, Taylor Probst, Dallin Kohler, Alison Whiting, Jacob Searcy Mar 2023

Mystifying Mimics: The Influence Of Distribution On Mimicry, Taylor Probst, Dallin Kohler, Alison Whiting, Jacob Searcy

Library/Life Sciences Undergraduate Poster Competition 2023

Many animals display bright colors or patterns to advertise or warn predators that they are dangerous. Coral snakes effectively use bright red and yellow bands to warn of their venom. There are also many harmless snakes which try to copy or mimic the color patterns of the coral snakes to gain that same protection from predators without the venom. This is known as Batesian mimicry. It has long been thought that for mimicry to be effective, both the dangerous animals and their mimics need to be found in the same geographic area. This study focuses on two species of kingsnake, …

Thc On The Brain: Adult Vs. Adolescent Changes, Addison Smartt, Jeffrey Edwards Phd Mar 2023

Thc On The Brain: Adult Vs. Adolescent Changes, Addison Smartt, Jeffrey Edwards Phd

Library/Life Sciences Undergraduate Poster Competition 2023

Δ9 -tetrahydrocannabinol (THC) has been demonstrated to cause elimination of cannabinoid 1 receptor (CB1) mediated long term depression (LTD) of GABA neurons in the ventral tegmental area (VTA) of the brain. Through electrophysiology and quantitative PCR experiments, this study reveals that LTD elimination is more pronounced in adolescents than adults, giving an explanation for the increased risk of THC dependency in adolescence. However, after a seven day withdrawal period, these effects were reversed. The data also supports the hypothesis that removal or desensitization of CB1 receptors from the synapse is an important mechanism of THC-induced neural and cognitive changes.

Valproic Acid Affects Neuronal Specification And Differentiation During Early Optic Tectum Development Of Zebrafish, Sierra C. Dixon, Bailey J. Calder, Shane M. Lilya, Brandon M. Davies, Annalie Martin, Maggie Peterson, Jason M. Hansen, Arminda Suli Mar 2023

Valproic Acid Affects Neuronal Specification And Differentiation During Early Optic Tectum Development Of Zebrafish, Sierra C. Dixon, Bailey J. Calder, Shane M. Lilya, Brandon M. Davies, Annalie Martin, Maggie Peterson, Jason M. Hansen, Arminda Suli

Library/Life Sciences Undergraduate Poster Competition 2023

The mammalian superior colliculus and its non-mammalian homolog, the optic tectum (OT), are midbrain structures that integrate multimodal sensory inputs and guide non-voluntary movements in response to prevalent stimuli. Recent studies have implicated this structure as a possible site affected in Autism Spectrum Disorder (ASD). Interestingly, fetal exposure to valproic acid (VPA) has also been associated with an increased risk of ASD in humans and animal models. Therefore, we took the approach of determining the effects of VPA treatment on zebrafish OT development as a first step in identifying the mechanisms that allow its formation. We describe the normal OT …

Tyrannies Gave Rise To Martial Arts, But Enlightened Martial Philosophies Reveal A Better Way, Michael Andregg Mar 2023

Tyrannies Gave Rise To Martial Arts, But Enlightened Martial Philosophies Reveal A Better Way, Michael Andregg

Comparative Civilizations Review

Most of this brief review will be academic history, but one of the truisms of the martial arts is that it is never strictly “academic.” Words on paper cannot express some things at the heart of the art. Many of the most thoughtful masters of various schools have worried about how to cultivate students with the discipline and philosophical background to be “safe” for polite society. This is a similar problem for police departments and even armies. The best wish to train professionals in ways of being deadly, without empowering undisciplined people to harm innocents. Therefore, part of this paper …

Undernutrition Among Children In Guatemala, Ellie Ostvig Mar 2023

Undernutrition Among Children In Guatemala, Ellie Ostvig

Ballard Brief

Undernutrition in Guatemala is a serious issue that affects physical, mental, and social well-being. Children are most vulnerable to this dangerous condition, and in Guatemala, almost 50% of children experience inadequate growth and development due to a lack of appropriate nutrient intake. Because of food insecurity and lack of nutrients, young children do not have adequate access to the nutrition that they need. Guatemala is located in an area that makes it prone to natural disasters, which also contributes to the high rates of undernutrition. Undernourished children also experience intense disadvantages because of their weakened immune systems and cognitive underdevelopment. …

Coloration Strategies In Sympatric Vietnamese Damselflies, Eva J. Driggs, Seth M. Bybee Feb 2023

Coloration Strategies In Sympatric Vietnamese Damselflies, Eva J. Driggs, Seth M. Bybee

Library/Life Sciences Undergraduate Poster Competition 2023

Odonates (dragonflies and damselflies) have evolved vibrant coloration for various reasons. Odonates use color signals to identify their own species from others and potential mates. Some Odonates use blue color to blend into the water while others are only active when their color can best be seen. Different selective pressures will evolve a specific color strategy. Color is a key to understanding the evolutionary pressures for damselflies. Color has not been studied in depth for Vietnamese Odonates, even though Vietnam is a top 15 biodiversity hotspot. We hope to better understand color evolution in Vietnamese damselflies and the role …

County-Level Social Determinants Of Health And Covid-19 Health Outcomes, Bret R. Lyman Feb 2023

County-Level Social Determinants Of Health And Covid-19 Health Outcomes, Bret R. Lyman

Theses and Dissertations

Social determinants of health are associated with a variety of negative health outcomes, including COVID-19 morbidity and mortality. However, most research evaluating this relationship have been case studies, retrospective cohort studies, and case series studies and/or have used use analytic techniques, such as linear regression, that can struggle to adequately model the social determinants' complex nature. This study used United States county-level social determinants of health data and March 2020-December 2020 COVID-19 morbidity and mortality data. Structural equation modeling was used to develop a latent measurement model for the social determinants of health. Substantial cross-loadings among the social determinants of …

Developing Methods For Measuring In Vivo Lipid Metabolism, Russell L. Denton Feb 2023

Developing Methods For Measuring In Vivo Lipid Metabolism, Russell L. Denton

Theses and Dissertations

Lipid metabolism is critically important to the normal function of individual cells and for signaling between tissues of the human body. There is a great need to quantify changes in lipid metabolism because of its implications in both normal healthy conditions and during disease development. In our first study, we developed a liquid chromatography mass spectrometry based workflow to assess in vivo metabolism of murine brain lipids. This involved sample preparation, data acquisition, and analysis software development and improvements. Regarding sample preparation, we maintained the mice at 5% body water for the duration of the experiment. As mouse metabolism proceeds, …

Hard To Be Won: A Theatrical Interpretation Of Elizabeth Keckly’S “Behind The Scenes, Or Thirty Years A Slave And Four Years In The White House”, Selah Degering Feb 2023

Hard To Be Won: A Theatrical Interpretation Of Elizabeth Keckly’S “Behind The Scenes, Or Thirty Years A Slave And Four Years In The White House”, Selah Degering

Undergraduate Honors Theses

Hard to Be Won is a musical adaptation of a memoir by Elizabeth Keckly, a black woman of considerable success who earned the confidence of Abraham Lincoln and his wife, Mary, in war-torn 1860s America. My adaptation of this story showcases a new perspective: that of Elizabeth herself. Despite her memoir narrating these events in her own voice, Elizabeth as an individual has been largely ignored or misrepresented in modern, idealistic, and racially ignorant retellings and criticism. Elizabeth as a token black person in the narrative of the Lincoln household cannot stand as representation of this woman’s legacy when she …

Territorial Intrusion By Resident Male Wilson's Warblers: Breeding Stages Of The Intruders And Distances They Travel, William M. Gilbert Feb 2023

Territorial Intrusion By Resident Male Wilson's Warblers: Breeding Stages Of The Intruders And Distances They Travel, William M. Gilbert

Western North American Naturalist

It now is generally recognized that genetic monogamy is the exception in birds, and that extrapair paternity in territorial species requires that one or the other sex involved in such an extrapair mating travel off its own territory to obtain an extrapair copulation. However, which sex or sexes travel off their home territories, the distances they might travel to obtain extrapair copulations, and the breeding stages during which they might make such off-territory forays are poorly understood for most species. I explored these issues in Wilson’s Warblers (Cardellina pusilla) in central, inner-coastal California. Male Wilson’s Warblers frequently intruded …

The New Cd Set From Immortal Performances: Essential Listening, Henry Fogel Feb 2023

The New Cd Set From Immortal Performances: Essential Listening, Henry Fogel

Journal of the Jussi Björling Societies of the USA & UK

Almost all performing artists exhibit differences between their studio recordings and their live performances (and, hopefully, also between different live performances). The degree of that difference can vary mightily from artist to artist. One tenor in whom this difference was very strongly pronounced was Jussi Björling. As fine as his studio recordings are, and some of them are extraordinary, the intensity and musical imagination he brought to live performances invariably increase compared with what we hear on his studio records. This remarkable compilation from Immortal Performances is essential listening for anyone who admires the great Swedish tenor. The three performances …

Steering Particles Via Micro-Actuation Of Chemical Gradients Using Model Predictive Control, Mark N. Mcdonald, Cameron K. Peterson, Douglas R. Tree Feb 2023

Steering Particles Via Micro-Actuation Of Chemical Gradients Using Model Predictive Control, Mark N. Mcdonald, Cameron K. Peterson, Douglas R. Tree

Faculty Publications

Biological systems rely on chemical gradients to direct motion through both chemotaxis and signaling, but synthetic approaches for doing the same are still relatively naïve. Consequently, we present a novel method for using chemical gradients to manipulate the position and velocity of colloidal particles in a microfluidic device. Specifically, we show that a set of spatially localized chemical reactions that are sufficiently controllable can be used to steer colloidal particles via diffusiophoresis along an arbitrary trajectory. To accomplish this, we develop a control method for steering colloidal particles with chemical gradients using nonlinear model predictive control with a model based …

Dengue Fever In South And Southeast Asia, Mikaela D. Lubin Feb 2023

Dengue Fever In South And Southeast Asia, Mikaela D. Lubin

Ballard Brief

Dengue fever is a mosquito-borne illness that impacts South and Southeast Asia at significant rates. It is carried primarily by the aedes aegypti mosquito, a species that thrives in warm, tropical climates. Features of dengue include excruciating pain and, in severe cases, internal bleeding, shock, and death. The spread of dengue in South and Southeast Asia is due to several factors, including advancements in transportation, poor preventative measures, poor sanitation, and subsequent standing water, which is an ideal breeding ground for mosquitoes. Dengue causes many negative consequences on individuals and communities it affects, including pain and suffering, lasting physiological effects, …

Forgotten Brother Reuben Lewis: Missouri River Fur Trader And Indian Agent For The Arkansas Cherokees, Jay H. Buckley, Deveney Reber Feb 2023

Forgotten Brother Reuben Lewis: Missouri River Fur Trader And Indian Agent For The Arkansas Cherokees, Jay H. Buckley, Deveney Reber

Faculty Publications

Reuben Lewis was born in 1777, the fourth and youngest child of William Lewis and Lucy Meriwether. Their oldest child, Jane, married and lived out her days at Locust Hill, the family estate in Virginia. The Lewis’ second child, baby Lucinda, died in infancy. Their third child, Meriwether – the closest in age and friendship to Reuben – became the famous first half of the Lewis and Clark Expedition which explored the uncharted West before he met his tragic and mysterious death on the Natchez Trace in Tennessee. While Reuben’s life has been rightly overshadowed by his older brother Meriwether’s …

Freemasonry And The Origins Of Latter-Day Saints Temple Ordinances, Jeffrey M. Bradshaw Jan 2023

Freemasonry And The Origins Of Latter-Day Saints Temple Ordinances, Jeffrey M. Bradshaw

Interpreter Foundation Books

My first exposure to The Church of Jesus Christ of Latter-day Saints came in 1988 when I first met my future wife, a dedicated member of the Church. She was pleased to answer any questions I had and to share insights into her beliefs, but I was uninterested in pursuing any serious inquiry into their teachings.

The Effect Of Alcohol On Lipid Membrane-Membrane Fusion And Snare Proteins, Robert E. Coffman Jan 2023

The Effect Of Alcohol On Lipid Membrane-Membrane Fusion And Snare Proteins, Robert E. Coffman

Theses and Dissertations

Currently the treatment of alcohol use disorder is very difficult and often requires the combination of therapy and medications, with many who undertake treatment experiencing relapse over time. There is also no treatment in use to prevent the development of alcohol use disorder. It is the aim of this work to provide information that may be useful for the development of a preventative treatment for developing alcohol use disorder by elucidating more of the acute effects of alcohol use. It is known that these effects originate in the brain. Within the brain are circuits made up of neurons that communicate …

Investigating New World Volcanism At The Time Of Christ’S Death Jan 2023

Investigating New World Volcanism At The Time Of Christ’S Death

Insights: The Newsletter of the Neal A. Maxwell Institute for Religious Scholarship

A recent article in the Journal of Book of Mormon Studies reported that ice cores taken from Greenland and Antarctica yield evidence broadly consistent with the 3 Nephi 8 account of cataclysmic New World events—presumably including a violent volcanic eruption—at the time of Christ’s death (Benjamin R. Jordan, “Volcanic Destruction in the Book of Mormon: Possible Evidence from Ice Cores,” JBMS 12/1 [2003]: 78–87). What other methods might yield corroborating evidence of
such an eruption? Two possibilities are the analysis of tree rings and sea and lake sediments.

Engineering At-Home Dilution And Filtration Methods To Enable Paper-Based Colorimetric Biosensing In Human Blood With Cell-Free Protein Synthesis, Tyler J. Free, Ryan W. Tucker, Katelyn M. Simonson, Sydney A. Smith, Caleb M. Lindgren, William G. Pitt, Bradley C. Bundy Jan 2023

Engineering At-Home Dilution And Filtration Methods To Enable Paper-Based Colorimetric Biosensing In Human Blood With Cell-Free Protein Synthesis, Tyler J. Free, Ryan W. Tucker, Katelyn M. Simonson, Sydney A. Smith, Caleb M. Lindgren, William G. Pitt, Bradley C. Bundy

Faculty Publications

Diagnostic blood tests can guide the administration of healthcare to save and improve lives. Most clinical biosensing blood tests require a trained technician and specialized equipment to process samples and interpret results, which greatly limits test accessibility. Colorimetric paper-based diagnostics have an equipment-free readout, but raw blood obscures a colorimetric response which has motivated diverse efforts to develop blood sample processing techniques. This work uses inexpensive readily-available materials to engineer user-friendly dilution and filtration methods for blood sample collection and processing to enable a proof-of-concept colorimetric biosensor that is responsive to glutamine in 50 µL blood drop samples in less …

Inadequate Immigration System For Asylum Seekers At The Us-Mexico Border, Kyli F. Soug Jan 2023

Inadequate Immigration System For Asylum Seekers At The Us-Mexico Border, Kyli F. Soug

Ballard Brief

The history of immigration in the US goes back to its founding. However, in recent years, immigration trends at the US-Mexico border have gained media and political attention as more migrants flee to the border and face challenges as they seek refuge in the US. The inadequate immigration system has been exacerbated as legislation like the Migrant Protection Protocols and metering complicates the legal system and forces asylum seekers into border towns. Border patrol's misuse of resources and insufficient immigration data also contributes to the inadequate immigration system. Families and individuals seeking legal asylum at the border are being detained …

Effects Of Plastic And Waste Pollution On Ocean Communities In The Asian Pacific Region, Whitney Kingsolver Jan 2023

Effects Of Plastic And Waste Pollution On Ocean Communities In The Asian Pacific Region, Whitney Kingsolver

Ballard Brief

Plastic and waste pollution is a global problem, but it affects ocean communities in the Asia Pacific Region (APR) the most due to their lack of resources to process the pollution. Additionally, low-income areas in these countries need access to sustainable non-plastic packaging options, which increases the amount of plastic generated. Direct pollution leads to poor ocean health and the disruption of important industries like tourism or fishing. Plastic pollutants eventually break down, which creates microplastics and releases toxic chemicals. These pollutants damage ecosystems and severely harm marine life. The overwhelming amount of waste pollution in the APR also damages …
