Growth Differentiation Factor 5 Is A Paracrine Regulator Of Sarcopenic Obesity, Landen W. Saling

Graduate Theses and Dissertations

Sarcopenic obesity attributes to skeletal muscle loss more than sarcopenia and obesity alone. Individuals with SO suffer from the comorbidity of excess body fat and concurrent muscle mass loss due to aging. Growth differentiation factors (Gdfs) have never been recognized as playing a role in skeletal muscle maintenance in those with SO. Specifically, Gdf5, has been recognized as playing a part in Bone Morphogenic Protein signaling to activate protein synthesis and deactivate protein degradation via SMAD 1/5/8 and SMAD 4 complex. Using RNA sequencing, Gdf5 was identified as being significantly upregulated in SO mice. Purpose: To determine the cellular role …

Cyanobacterial And Microcystin Response To Nutrient Additions At Lake Fayetteville Throughout The 2021 Growing Season, Lillie Haddock

Graduate Theses and Dissertations

Harmful Algal Blooms (HABs) are becoming a global concern due to their increasing distribution, frequency, intensity, and the occurrence of toxins. While it is known that eutrophication influences algal blooms, there is less known about what triggers these HABs to produce toxins, especially microcystin. In this study, we conducted 21 community bioassays at Lake Fayetteville, a hypereutrophic reservoir in Fayetteville, Arkansas, from April-November 2021 to examine how the addition of phosphorous and nitrogen influence cyanobacteria concentrations, microcystin concentrations, and microcystin toxin production. These experiments included a control, nitrogen (1.0 mg/L as KNO3), low phosphorus (0.025 mg/L as K2HPO4), high phosphorus …

Toward Global Localization Of Unmanned Aircraft Systems Using Overhead Image Registration With Deep Learning Convolutional Neural Networks, Rachel Linck

Graduate Theses and Dissertations

Global localization, in which an unmanned aircraft system (UAS) estimates its unknown current location without access to its take-off location or other locational data from its flight path, is a challenging problem. This research brings together aspects from the remote sensing, geoinformatics, and machine learning disciplines by framing the global localization problem as a geospatial image registration problem in which overhead aerial and satellite imagery serve as a proxy for UAS imagery. A literature review is conducted covering the use of deep learning convolutional neural networks (DLCNN) with global localization and other related geospatial imagery applications. Differences between geospatial imagery …

Evaluation Of The Effect Of A Lippia Organoides Essential Oil Extract On Clostridium Perfringens Proliferation In Vitro And Necrotic Enteritis In Broiler Chickens, Makenly E. Coles

Graduate Theses and Dissertations

The purpose of the present research was to assess the effects of essential oils derived from the plant Lippia organoides on performance parameters, intestinal integrity, and necrotic enteritis (NE) in broiler chickens. To do this, a previously established challenge model for NE was utilized which included challenging with Salmonella Typhimurium on day 0, Eimeria maxima on day 18, and Clostridium perfringens on days 22 and 23. Treatment groups included a 1) non-challenged, negative control, 2) challenged control, and 3) challenged, Lippia origanoides (37ppm in the diet). Group 1 (negative control) had significantly (P < 0.05) higher body weight gain from d8-25 and d0-25 compared to both challenged groups. Feed intake was significantly different for all three groups (P < 0.05) at 8-25 days and 0-25 days with group 1 having the highest feed intake for both time periods. Total mortality was greater in the positive control when compared to both the negative and treatment groups. NE lesion scores were significantly different between all groups with the positive control having the highest mean lesion scores and the negative control having a mean lesion score of 0. The positive control group had the highest FITC-d amounts detected in the sera, being statistically higher than both the treatment group and negative group which were both statistically different from each other. At the present inclusion rate for the essential oil (37 ppm), there was an overall reduction in the negative impact from the NE infection. Further studies should be conducted to reach more significant conclusions.

How Abortion Laws Do And Don't Work, Michelle Oberman

Faculty Publications

The US Supreme Court appears ready to permit states to re-criminalize abortion. When the “law on the books” changes in the United States, what might the “law on the ground” look like? One answer lies in examining what happens today, in countries with restrictive abortion laws. Israel’s 1977 law bars abortion unless approved by a “pregnancy termination committee.” Drawing on interviews with committee members, lawmakers, advocates and others, this Article presents an ethnographic study of one country’s experience with a law criminalizing abortion.

Israel’s approach, limiting abortion access to those with qualifying conditions, is likely to be in play for …

Understanding Interfacial Reactions Initiating On Electrode Materials For Energy Storage Technologies, Jingnan Li

Graduate Theses and Dissertations

Since the first generation of lithium-ion batteries featured lithium cobalt oxide cathode and carbon anode commercialized in the 1990s, the high-capacity materials with lower cost are in demand to further increase the battery energy density. Lithium metal and silicon anode are promising high-capacity anode materials to achieve next-generation lithium batteries. However, both the materials actively react in electrolytes and suffer from dramatic volume change. Therefore, a reliable passivation layer at the electrolyte/electrode interphase (i.e., solid electrolyte interphase, or “SEI”) is required to support the long-term cycling of both materials. Cetrimonium hydro fluoride (CTAHF2) has been proposed and synthesized as an …

Historical Underpinnings And Consequent Effects Of Labor Exploitation Of Mexican And Central Americans In The United States, Andrew Elkins

World Languages, Literatures and Cultures Undergraduate Honors Theses

The experience immigrants have today working and living in the southern United States is defined by systems that have developed out of lingering racist attitudes and reactions toward these individuals. The flow of people across the U.S.-Mexico border has a long history, and it is characterized by patterns that have continued from early guest worker programs to the present-day flow of migrants, both legal and undocumented. Also continually present is the racialization of these migrants, which has often forced them to work and live as marginalized members of American society. This project will explore the establishment of Mexican American citizen …

Compatible Blends Of N-Type Polymer Semiconductors: Impact On The Morphology And Mechanics Of Flexible Optoelectronics, Zachary C. Ahmad

Honors Theses

Conjugated polymers offer the potential for the development of robust, low-cost electronics, but achieving high mechanical deformability and high charge transport simultaneously in polymer semiconductors remains a significant challenge. In this work, blends of conjugated polymers were investigated to elucidate the influence of compatible conjugated blends on polymer morphology, mechanics, and electrical properties (using a partially conjugated polymer as the soft matrix and a fully conjugated polymer as the electrically active component). This work achieves a fundamental understanding of blend morphology for these similar components by establishing the framework for how they deform with strain. Grazing-incidence wide-angle X-ray scattering (GIWAXS) …

Investigating The Effect Of Polymer Hydrogels On The Antimicrobial Properties Of Activated Carbon Through The Utilization Of Bacterial, Viral, And Parasitic Microorganisms, Zoe Gunter

Honors Theses

Activated carbon (AC) has long been utilized in biomedical applications due to its innate antimicrobial characteristics. However, little is understood about the mechanism of action that allows AC to prohibit the propagation of different pathogen species. To further ascertain these characteristics and how they affect the propagation of pathogens, procedures were designed with bacterial, viral, and parasitic agents which were utilized in conjunction with varying concentrations of polymer hydrogels to examine the antimicrobial efficacy of AC. The studies performed for this thesis were conducted employing coconut-based AC and Noveon^® AA-1 Polycarbophil USP or Carbopol^® 974P NF hydrogels which, …

Fault-Free Tilings, T. Elise Dettling, Amelia Goetzinger

Mathematics Undergraduate Research

Given a p×q rectangular board (height p and width q), we may fill in the area with 2×1 tiles. We say the board is tileable if the board can be filled with non-overlapping tiles leaving no open space. Not all boards are tileable, for example a 5 × 5 board is not tileable because it has an odd area. A fault-free tiling exists on the board if every line through the board parallel to a side goes through a tile. Previous work on this subject has been completed by Ron Graham in “Fault-Free Tilings of Rectangles" and Emily Montelius in …

Evaluation Of Human Microbiota-Associated (Hma) Porcine Models To Study The Human Gastrointestinal Microbiome, Nirosh D. Aluthge

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Research conducted in the past couple of decades has showcased the importance of the gut microbiota in human health and well-being. While many studies have reported on the differences in community membership between a disease state and a healthy state, few have investigated the mechanisms through which an aberrant microbiota contributes to a disease phenotype. One of the primary reasons for this are the many technical and ethical barriers to conducting the necessary studies directly in human individuals. Human microbiota-associated (HMA) porcine models have the potential to become important research tools which can enable the testing of hypotheses regarding host-microbiota …

The Utility Of The Dibels Phonemic Segmentation Fluency Assessment In Kindergarten For Establishing A Correlation With Third Grade Reading Performance, Jennifer Lynn

Masters Theses/Capstone Projects

The purpose of this study is to investigate whether student scores on the kindergarten DIBELS PSF assessment are correlated with student reading assessment scores in third grade. I chose to examine this correlation because the kindergarten PSF score is used as one of the earliest identifiers of students who are at-risk for reading difficulties. I determined that a small number of those students who scored at-risk in kindergarten remained at-risk in the third grade.

The results of the study revealed that there is notable agreement as to the importance of various components related to effective board governance in covenantal schools; however, there are a few areas where boards in covenantal schools may have opportunity for growth. These include …

Memory Hunger: A Geocritical Study Of Nostalgia And The Glorification Of Paris In Works Written By Lost Generation Writers During The Interwar Period., Gabrielle Vatthanatham

English Undergraduate Honors Theses

The literary representations of Paris in the works of the Lost Generation communicate a nostalgia, longing for, and glorification of an irrecoverable past. The romanticization and abstraction of the setting of Paris in the works of the Lost Generation elucidates the emotional situations of their characters as they contemplate the nature of their existence. The abstraction of Paris liberates the city from its physical locale and demonstrates the repressional mechanisms of anchoring and sublimation outlined by existential philosopher Peter Wessel Zapffe in his essay “The Last Messiah.” In the connection of Paris with Zapffe’s existential theory, Paris becomes, for certain …

The Hot Springs Creekway & The Rediscovery Of The Water That Made Hot Springs Famous, Zane Colvin

Landscape Architecture Undergraduate Honors Theses

Arkansas’s Hot Springs National Park was the first natural reservation in the United States and is the oldest park in the National Park System. In Hot Springs, 47 springs release almost a million gallons of potable 143° water every day - the problem is, almost all of this water is hidden from sight, funneled directly into an 1884-constructed tunnel underground, where no person (or other life) can experience it.

Hot Springs Creek should be daylighted and connected with the surrounding National Park, creating thermal 'pools' for public use, and restoring its banks to pre-settlement ecologically rich conditions. My plan to …

Zine As Rebellion Against The Cultural Dominance Of Digital Self-Publishing, Matthew Hono

RhetTech

Many have questioned the role and relevance of zines during the digital age. Zines are DIY magazine-like publications, usually made of paper. Scholars have conceptualized digital forms of self-publishing, such as blogging, as the modern equivalent of zine-making, replacing the older technology. However, the continued production of zines suggests that the medium might overcome some of the issues that plague digital publishing. The present study examines previous scholarship, articles, and interviews to understand why individuals still decide to create zines. It was found that zines may offer a more intimate reading experience, increased safety from censorship and harassment, an opportunity …

Evaluating The Shark Deterrent Effects Of The Novel Exclusion Barrier In Comparison To The Rigorously Tested Sharksafe Barrier Technology, Craig P. O’Connell, Julia Crews, Andre King, Juliet Gressle

Marine Science

Although exceedingly rare, shark attacks have a disproportionately large impact on human behavior, often resulting in shark culls. Due to the invasive nature of shark culls, innovating and testing non-invasive deterrent technologies that may minimize the potential for a rare negative shark encounter has become a conservation priority. One such mitigation approach is barriers, such as exclusion nets and the Sharksafe barrier. With both technologies exhibiting limitations and/or ineffectiveness (e.g., Sharksafe barrier), the development of a more effective technology was warranted. Therefore, this study had two key objectives: (1) to determine if DC 12 Volts 180 Newtons electromagnets can produce …
