Calculations From On The Existence Of Periodic Traveling-Wave Solutions To Certain Systems Of Nonlinear, Dispersive Wave Equations, Jacob Daniels

Mathematics and Statistics Student Research and Class Projects

In the field of nonlinear waves, particular interest is given to periodic traveling-wave solutions of nonlinear, dispersive wave equations. This thesis aims to determine the existence of periodic traveling-wave solutions for several systems of water wave equations. These systems are the Schr¨odinger KdV-KdV, Schr¨odinger BBM-BBM, Schr¨odinger KdV-BBM, and Schr¨odinger BBM-KdV systems, and the abcd-system. In particular, it is shown that periodic traveling-wave solutions exist and are explicitly given in terms of cnoidal, the Jacobi elliptic function. Certain solitary-wave solutions are also established as a limiting case of the periodic traveling-wave solutions, that is, as the elliptic modulus approaches one.

Cocoa Polyphenols Modulate The Fecal Microbiome In A Mouse Model Of Colitis, Independent Of Basal Diet And Colon Inflammation, Abby D. Benninghoff

Browse all Datasets

Chronic inflammation increases the risk of developing multiple chronic diseases, including cancer. The risk of developing colorectal cancer (CRC) specifically is increased in individuals who suffer from colitis, a characteristic of Inflammatory Bowel Disease (IBD). Diet is another risk factor for developing CRC, particularly an inflammation-promoting Western-type diet. Thus, supplementing a Western diet with functional foods containing anti-inflammatory polyphenols is a potential approach to decreasing CRC risk by reducing gut inflammation and altering gut microbiome profile. This study aimed to determine the effects of cocoa polyphenol (CP) supplementation on inflammation status and microbiome profile before, during, and after colitis when …

Data Set: The Analysis Of Lava Flow Path Using Remote Sensing Techniques And Geomorphological Techniques: The Case Of Volcano Eruptions In Afar Region Of Ethiopia, Oluwatosin Ayo, Jae Sung Kim

Michigan Tech Research Data

Natural disasters pose significant threats to the environment and make land unsuitable for man. The lava from volcanic eruptions rapidly moves on the Earth surface and affects both natural and man-made features on the Earth. Remote sensing is relevant in extracting information about the areas affected by lava flows without physically visiting such areas. The objective of this study is to develop a workflow for determining the optimal ground sample distance of a digital elevation model to delineate the lava flow paths using object-based image analysis and geomorphologic analysis. For the experiment, the satellite images and digital elevation model of …

Environmental Factors Associated With Triploid Aspen Occurrence In Intermountain West Landscapes, Karen E. Mock, James A. Walton

Browse all Datasets

Polyploidy is common among plants and can contribute to physiological and morphological differences, altering how plants respond to environmental changes, promoting genetic diversification, and even species radiation. Quaking aspen (Populus tremuloides), a keystone species associated with high plant and animal diversity is frequently found in mixed diploid/triploid populations in the Intermountain West. High mortality rates and widespread population declines in aspen are of increasing concern in the Intermountain West, often ascribed to changing climates and drought stress events. The goal of this study was to better understand environmental factors influencing the distribution of triploid aspen population in the Intermountain West. …

Yayoi Kusama’S Depictions Of Mental Health, Anna Isabel Davis

Butler Journal of Undergraduate Research

This paper examines Yayoi Kusama’s usage of art as a coping mechanism for her mental illness, particularly through her pumpkins and “nets” motifs. It involves a close analysis of three artworks to emphasize this motif: her first depiction of pumpkins; “nets”; and, finally, her combination of both pumpkins and “nets” into one artwork. Her theme of repetitions as meditative force is evident in each of these works. As such, this paper posits that the goal of her art is not to heal from her mental illness but to better cope and adapt. This research draws on various primary sources, including …

Partake Or Be Departed: Insularity Of Setting Within The Dystopian Imagination And The Mark: The Beast Rules The World, Andrew Watkins

Butler Journal of Undergraduate Research

Insularity of setting within the dystopia is a motif that is shared between works of dystopian fiction and works in the utopian imagination as a whole. Each dystopia or utopia is unique in how it creates and uses insularity of setting to facilitate the confinement of its subjected society to a prescribed set of social, political, religious, and economic practices. Timothy LaHaye and Jerry B. Jenkins use the framework of rapture fiction and the motif of insularity of setting to create an international dystopia in their novel The Mark: The Beast Rules the World. The global insularity conceived within The …

The Roycean Communal Ideal In T. S. Eliot's “The Love Song Of J. Alfred Prufrock”, Micah Gill

Butler Journal of Undergraduate Research

T. S. Eliot’s poem “The Love Song of J. Alfred Prufrock” has often been read as a thoroughly cynical assessment of the modern individual and community. This totalizing portrayal misses the poem’s ability to serve as a foil to a more ideal community. If Eliot is so ill-disposed to the timid, fragile Prufrock and his shallow, ostentatious social network, then Eliot must believe in the essence of a better community. We may look to one of Eliot’s intellectual mentors, Josiah Royce, for his philosophy of community, which stands as an ideal inverse in relation to the Prufrockian community. After examining …

Effects Of Dissolved Oxygen On Northern Leopard Frog (Lithobates Pipiens) Gastrocnemius Muscle Recruitment And Fatigue, Eva L. Gates, Joseph P. Levri

Butler Journal of Undergraduate Research

Dissolved oxygen levels in aquatic systems have decreased because of temperature increases caused by climate change, which in turn has affected ecosystems and wildlife. Many physiological processes in aquatic organisms require a certain dissolved-oxygen range, and decreasing levels can compromise proper functioning. Previous studies have linked muscle performance to dissolved oxygen levels in a variety of aquatic species, but less research has been dedicated to amphibians. Because many amphibians engage in cutaneous respiration, especially when dwelling in aquatic habitats, dissolved oxygen levels may have a significant impact on muscle performance in this taxon. This experiment investigated the effects of dissolved …

Discrimination By Association: The Role Of Race And Exoneration In Hiring Decisions, Emma Bergquist

Butler Journal of Undergraduate Research

People convicted of felonies are often discriminated against when applying for jobs after prison (Mikkelson & Schweitzer, 2019). Interestingly, exonerated individuals are also discriminated against upon their release, even though they were wrongfully convicted. To date, there has been no direct comparison of the discrimination between these two groups when they are applying for jobs. The present study closes this gap by comparing the application strength of candidates with varying categories of race, legal status, and community support. We collected data from 299 CloudResearch participants online and presented them with job application materials that they evaluated as if they were …

Work-Life Balance In A Medical Unit Of U.S. Army Reservists: An Exploratory Study, Elizabeth A. Kleitz, Madelyn Huhn

Butler Journal of Undergraduate Research

Work-family life balance influences employee job satisfaction and quality of life. When work and family life are in balance, employees perform at higher levels and have fewer health problems. U.S. Army Reservists in both civilian and Reserve medical occupations may face work-life balance conflicts from both their full-time/ civilian and part-time/military medical occupations. Army Reservists in a medical unit were surveyed about their work-family life balance behaviors using the Work–Life Climate Scale in an exploratory cross-sectional study. Most reported rarely experiencing work-life conflict behaviors; however, many also reported that they worked late three to seven days of the week. Long …

Comparing The Visuospatial Abilities Of Alzheimer’S Patients And Huntington’S Patients, Alysa Aralis, Emma Bauman

Butler Journal of Undergraduate Research

Visuospatial deficits emerge from the pathophysiology of both Huntington’s disease (HD) and Alzheimer’s disease (AD), but few studies have directly compared the types of visuospatial deficits associated with these disorders. We directly compared the mental rotation abilities of HD (n = 18) and AD (n = 18) patients relative to age-matched control groups (young healthy controls: n = 20; older healthy controls: n = 20). Participants completed the nonrotational and rotational components of the Right-Left Orientation Test (RLOT), Luria, Money Road Map Test (MRMT), and Stick Construction Test (SCT). Participants also indicated the strategy they used to complete each: personal …

The Influence Of Specific Diagnosis And Trait Self-Relevance On Positive And Negative Perceptions Of Individuals With Mental Illness, Sabrina L. Stock, Aedan S. Levy

Butler Journal of Undergraduate Research

We investigated how participants perceived an individual with either depression, schizophrenia, or no disorder on negative and positive traits and then examined how these perceptions linked to desire for social distance (DSD), trait self-relevance, positive former contact with a person with mental health problems, and continuum beliefs. One hundred fifty undergraduates completed an online survey that described a vignette character with depression (VCWD), vignette character with schizophrenia (VCWS), or control character with no mental disorder (CC) and assessed participants’ perceptions of the character’s traits, DSD from the vignette character, perceptions of one’s own traits, and demographic characteristics. In general, the …

Stream Gauging: Investigating The Flow Rate And Residence Time In Laguna Bacalar, Mexico, Elizabeth J. Kowalczyk

Butler Journal of Undergraduate Research

Stream gauging is a standard tool used to measure the flow rate of various bodies of water. Knowing the flow rate of a body of water allows for the residence time of a body of water to be calculated. Currently, there is very little information regarding the flow rate and residence times of Laguna Bacalar. This system has been observed hydrologically consistently only in the past 6 years. In this study, 13 stream-gauging locations of interest were identified and gauged for their respective flow rates using the midsection method. Once the flow rates were acquired, maps depicting the Laguna Bacalar …

Infiltrating The Boys’ Club: The Portrayal Of Women In Popular Crime Dramas, Emma D. Bergquist

Butler Journal of Undergraduate Research

The present study examines whether there has been a change in the portrayal of female criminal investigators over the past two decades. Cultivation theory suggests that media profoundly influences the views of the larger society, thus indicating significant implications of this portrayal. Five popular shows (Chicago P.D., Criminal Minds, CSI: Crime Scene Investigation, Hawaii Five-0, and Law & Order: SVU) were explored, with 200 episodes examined between the series using a mixed-methods approach. The main characters in each show’s first season and most recent season were coded and analyzed. Characters were coded for depth, authority, helplessness, and sexualization, among other …

Populism: A Comparative Study Of The Rise Of The Alt-Right In Germany And The United States, Kate O. Tobin

Butler Journal of Undergraduate Research

The far-right extremist movements in Germany and the United States have gained attention and proved concerning, manifesting in the forms of terrorism, nationalism, and xenophobia. The radical right often utilizes populism to undermine liberal institutions, with a proneness to discrimination and violence. Right-wing populism in Germany has been a movement founded on fear, which has expanded to include governmental and political institutions. In the United States, populists often criticize the political elite for catering to the needs of minorities. The influence of the economic crisis on the lower-income, blue-collar areas of the country has been impactful enough to allow for …
