The Discovery Of Metarhizium Anisopliae (Metchnikoff) Sorokin Isolates From Arkansas And Their Pathogenicity To Amblyomma Americanum L., Austin Goldsmith

Graduate Theses and Dissertations

The lone star tick Amblyomma americanum L. is the most abundant tick in Arkansas and has been implicated as a vector of many important disease-causing pathogens. Many species of entomopathogenic fungi have been isolated from several species of ticks, with some of these fungi being utilized for tick biocontrol. However, few studies have assessed the pathogenicity of entomopathogenic fungi to A. americanum. The objectives of this study were to: isolate and identify native Arkansas isolates of entomopathogenic fungi from wild A. americanum ticks exposed to soil and to compare the pathogenicity of one isolate (Metarhizium anisopliae (Metchnikoff) Sorokin isolate Savoy …

Intervals, Nicolette Bonagura

Graduate Theses and Dissertations

Intervals investigates the complexities of visual perception, using the camera as a tool to document time and light. The photograph is a restricted experience dually existing as a physical impression of light onto a surface and a fixed representation that makes light tangible. Using time and light as my subject and ritualistic gathering as my methodology, I explore the complexities of control and perception as they relate to photography. I collect images of everyday occurrences; and then use those as material to both compress and expand time. I do this to interrupt our understanding of it. Documenting time through mundane …

Do You Wanna Go Dancing?, Anthony Kascak

Graduate Theses and Dissertations

The transdisciplinary art work within Do you wanna go dancing? unpacks the experience and perception of my interpersonal relationships, as well as the role that touch and introspection has in my visual arts practice and everyday life. I am interested in pairing the act of looking with the sensation of touching through specific installation and arrangement of intimate imagery, ceramic fragments and frames, and manual or digitally fabricated surfaces. The negotiation of these installations orient the viewer to consider their positionality within space, as well as the extent in which distance, intimacy, and vulnerability fluctuate inside these psychological spaces.

The Effects Of Storage Temperature On The Bovine Nasal Microbiome, Hunter Usdrowski

Animal Science Undergraduate Honors Theses

Bovine respiratory disease (BRD) is one of the largest economic burdens facing United States beef producer’s modern day. The complexity in the onset and development of this multifactorial disease necessitates further insights into its functions to alleviate the tremendous consequences it generates for producers. The respiratory microbiome and their metabolomics play an important role to maintain health and predict BRD. However, due to low biomass, new technology is needed to increase the microbial concentration for omics (e.g. metatranscriptomics) research. In this study, a novel self-enrichment storage technique on the bovine nasal microbiome was performed and compared to a traditional nasal …

Association Of Single Nucleotide Polymorphisms In Bovine Heat Shock Protein 70, Cytochrome P450, Lactate Dehydrogenase, Interleukin 8 Receptor, And Melatonin Receptor 1a With Hoof And Udder Traits In Beef Cows, Maryrose Warren

Animal Science Undergraduate Honors Theses

Hoof and udder conformation are important to the longevity and productivity of beef cattle. Selection for hoof and udder quality reduces the incidence of lameness and udder disease to improve animal welfare. Genetic selection is an effective means of improving traits such as these, especially through the use of single nucleotide polymorphism (SNP) genotyping to identify indicator traits. This study used genotype data and hoof and udder scores from previous research to determine if there is significant effect between polymorphisms of heat shock protein 70 (Hsp70), cytochrome P450 (CYP450), interleukin-8 receptor (IL8), lactate dehydrogenase (LDH), and melatonin receptor 1A (MTNR1A), …

The different treatments were a control diet of 20% crude protein, a diet of 17% crude protein, and a diet of 17% crude protein with 10% S. platensis added to the feed. Body weight, feed intake, and mortality rate was not significantly different between treatments …

A Functional Escape, Zachary Spero

Architecture Undergraduate Honors Theses

Over the past two decades, the tree house has outgrown its more recent traditional role as a child’s place to play and has served many new functions. I intend to conduct research that questions how the tree house has evolved over the last twenty years based upon changes in program, technology, and relation to the tree itself. As a result of this research, I will deliver a clear understanding of tree house design best practices in the form of a manual.

The Social Lot: Reimagining The Future Of Surface Parking Lots In Kansas City, Missouri, Lauren Davis

Architecture Undergraduate Honors Theses

Currently, the world is experiencing a resurgence of the urban lifestyle as humanity undergoes its third great wave of human history, the metropolitan tide. Humanity’s advancement in the past few decades has made cities the largest technology possible. In 1952, only thirty percent of the population lived in cities, and by the end of the twenty-first century, eighty-five percent of the world’s population will be urban. With this influx of population in the urban landscape, it is pertinent now more than ever for cities to redesign the city for the pedestrian.

In the 1950s, there was a predominant reorganization of …

Impact Of Phosphorus Intake On Beef Heifer Growth Performance And Conception Rates, Hailey Hilfiker

Animal Science Undergraduate Honors Theses

This study aims to examine the effects of phosphorus intake on beef heifer growth performance and conception rates. In Northwest Arkansas, there has been an increase in phosphorus concentrations in soil where livestock manures have been repeatedly applied. Consequently, forages grown on soils high in phosphorus tend to contain high amounts of the mineral itself. This has led many to question whether it is necessary to supplement phosphorus in areas where concentrations may be higher. In this study, crossbred Angus heifers (n = 72), approximately 30 days after weaning, were stratified by body weight (average initial weight 251 ± 3.9 …

Surveillance Of Anaplasma Marginale In Arkansas Beef Cattle Herds, Gabriel Apple

Animal Science Undergraduate Honors Theses

Anaplasmosis is an economically devastating disease in cattle that is caused by the rickettsial pathogen Anaplasma marginale. It is estimated that this parasitic bacterium causes over $300 million in expenses for the U.S. cattle industry annually. In Arkansas, the beef cattle industry is the fifth largest agricultural commodity in the state, thus necessitating a better understanding of this disease along with its prevalence. In this study, both polymerase chain reaction (PCR) and competitive enzyme-linked immunosorbent assay (ELISA) tests were used to determine the prevalence of A. marginale infection in Arkansas beef cattle on pasture in the six commonly known geographical …

Dairy Tales: Global Portraits Of Milk And Law, Jessica Eisen, Xiaoqian Hu, Erum Sattar

Journal of Food Law & Policy

Cow’s milk has enjoyed a widespread cultural signification in many parts of the world as “nature’s perfect food.”1 A growing body of scholarship, however, has challenged the image of cow’s milk in human diets and polities as a product of “nature,” and has instead sought to illuminate the political, scientific, colonial and postcolonial, economic, and social forces that have in fact defined the production, consumption, and cultural signification of cow’s milk in human societies. This emerging attention to the social, legal, and political significance of milk sits at the intersection of several fields of academic inquiry: anthropology, history, animal studies, …

Milk And Law In The Anthropocene: Colonialism's Dietary Interventions, Kelly Struthers Montford

Journal of Food Law & Policy

It is widely accepted that we are living in the Anthropocene: the age in which human activity has fundamentally altered earth systems and processes. Decolonial scholars have argued that colonialism’s shaping of the earth’s ecologies and severing of Indigenous relations to animals have provided the conditions of possibility for the Anthropocene. With this, colonialism has irreversibly altered diets on a global scale. I argue that dairy in the settler contexts of Canada and the United States remains possible because of colonialism’s severing of Indigenous relations of interrelatedness with the more-than-human world. I discuss how colonialism—which has included the institution of …

Something To Celebrate?: Demoting Dairy In Canada's National Food Guide, Maneesha Deckha

Journal of Food Law & Policy

In early 2019, the Canadian Government released the much-anticipated new Canada Food Guide. It is a food guide that de-emphasizes dairy products and promotes plant-based eating. Notably, in the new version, milk and milk products are de-listed as one of the previously four essential food groups. On the surface, it seems that the federal government is promoting veganism and helping to bring about a friendlier future for animals and humans harmed by being producers and consumers of dairy, as the new Guide may seriously contract the currently robust Canadian dairy industry and its powerful lobby. On closer inspection, the messaging …

"A Glass Of Milk Strengthens A Nation." Law Development, And China's Dairy Tale, Xiaoqian Hu

Journal of Food Law & Policy

Historically, China was a soybean nation and not a dairy nation. Today, China has become the world’s largest dairy importer and third largest dairy producer, and dairy has surpassed soybeans in both consumption volume and sales revenue. This article investigates the legal, political, and socioeconomic factors that drove this transformation, and building upon fieldwork in two Chinese counties, examines the transformation’s socioeconomic impact on China’s several hundred million farmers and ex-farmers and political impact on the Chinese regime. The article makes two arguments. First, despite changes of times and political regimes, China’s dairy tale is a tale about chasing the …

Milk And The Motherland? Colonial Legacies Of Taste And The Law In The Anglophone Caribbean, Merisa S. Thompson

Journal of Food Law & Policy

This paper tells a story of the relationship between colonialism and capitalism through the lens of “milk” and “the law” in the Caribbean. Despite high levels of lactose intolerance amongst its population, milk is a regular part of many Caribbean diets and features prominently in its foodscapes. This represents a distinctive colonial inheritance that is the result of centuries of ongoing colonial violence and displacement. Taking a feminist and intersectional approach, the paper draws on analysis of key pieces of colonial legislation at significant historical junctures and secondary literature to do three things. Firstly, it examines how law aided the …

Redesign And Quantitative Assessment Of An Accelerated Venous Valve Fatigue Apparatus, Megan Kueh

Biomedical Engineering Undergraduate Honors Theses

Chronic venous insufficiency (CVI) is a form of cardiovascular disease that is caused when valves in the leg become incompetent. Current treatment methods serve to manage symptoms, but there are currently no ways to treat the underlying cause of CVI. A venous valve prosthetic made from a xenograft of a bovine jugular vein is one possible treatment method currently in the research phase. Prosthetic valves must be tested with an accelerated wear tester prior to approval for clinical testing. Although such testers exist for heart valves, physiological differences between heart and venous valves restrict the use those testers on venous …

The Efficacy Of Extended-Release Eprinomectin For The Reduction Of Horn Flies, Face Flies, And Fecal Egg Counts Of Parasitic Nematodes In Replacement Beef Heifers, Sophia F. Landers

Animal Science Undergraduate Honors Theses

The purpose of this study was to evaluate the efficacy of extended-release eprinomectin against horn flies, face flies, and fecal egg counts of parasitic nematodes in crossbreed replacement beef heifers. Fifty-four heifers were randomly placed into three treatment groups (N=18 heifers/treatment). Group 1 was administered the labeled dosage of extended-release eprinomectin on day 0. Group 2 acted as the negative control. Group 3 received the anthelmintic injection once a quarter of the heifers in the group reached the threshold treatment level for horn flies (N=200 flies/animal; day 41). Nematode infections were measured via fecal egg counts while horn and face …

Use Of Diatomaceous Earth And Copper Oxide Wire Particles To Control Gastrointestinal Nematodes In Lambs, Olivia Jones

Animal Science Undergraduate Honors Theses

Abstract

Anthelmintic resistance (AR) urges alternatives to control gastrointestinal nematodes (GIN). Copper oxide wire particles (COWP) are more efficacious when used with other dewormers and little is known on efficacy of diatomaceous earth (DE) to control gastrointestinal parasites. The objective was to examine the effects of DE and COWP on GIN control. Katahdin lambs (n = 32; ~150 d of age; 25.0 ± 1.8 kg) were randomly assigned to receive: 1) DE fed at an estimated 2% dry matter intake (with the assumption of moderate consumption of bermudagrass forage and provided supplement), 2) 1g COWP, 3) both 2% DE and …

Benefits Of Infant-Driven Feeding In The Neonatal Intensive Care Unit: A Literature Review, Maddison Carroll

The Eleanor Mann School of Nursing Undergraduate Honors Theses

Current policy in Neonatal Intensive Care Units (NICUs) is to prescribe a volume of formula or milk to ingest a certain number of times per day to infants admitted to the NICU. The method of infant-driven feeding (IDF) is believed to be a superior alternative that allows the infants to determine the timing and volume consumed and leads to better patient outcomes. To be considered in this review, the studies were required to be primary sources that were peer- reviewed, conducted in the last five years, and had to include at least one of three outcomes: weight gain, time to …

A Second Life: The Adaptation Of Dying Italian Towns To Accommodate Immigrants And Refugees, Rachel Rubis

Architecture Undergraduate Honors Theses

Despite its efforts in historic preservation, there is an abundance of culturally significant Italian vernacular towns dying due to dilapidation and depopulation. Simultaneously, Italy has faced an ongoing stream of immigrants and refugees seeking work, housing, and asylum within its borders—a crisis that has resulted in Italian fear and animosity aside immigrant maltreatment and hardship. My research, which is supplemented by first-hand experience in Italy, qualitative analysis, and text sources, proposes interventions into dying Italian towns to aid in the resettlement of immigrants and refugees—an effort meant to be mutually beneficial to both the town and the immigrant. In my …

Re-Evaluating Coverage Metrics For Wireless Sensor Network Border Security Applications, Kevin Haney

Industrial Engineering Undergraduate Honors Theses

Wireless sensor networks are an emerging technology used to monitor an environment over time. One specific application of the wireless sensor network is the border security application. Researchers have adapted coverage metrics from general wireless sensor network literature to fit the border security application. While some of the adapted metrics count the number of sensors detecting a potential target, others measure the distance between a potential target and its nearest sensor. No existing metric accounts for both of these factors. To take advantage of this gap and to attempt to increase the accuracy to which coverage is measured in this …

Impact Of Selected Infrared Wavelengths Treatment On Inactivation Of Microbes On Rough Rice, Rebecca Bowie

Food Science Undergraduate Honors Theses

The objective for this study was to investigate the impact of treating rough rice with selected infrared (IR) wavelengths at different IR intensities and heating durations, followed by a tempering step for further inactivation of microbes (mold and bacteria) on the grain. Freshly-harvested long-grain, hybrid, rough rice (XL 745) with initial moisture content (IMC) of 18.4% wet basis (w.b.) was used. Two-hundred grams (200 g) of the samples were treated at different IR wavelengths (λ) which were 3.2, 4.5, …

Midseason Nitrogen Sufficiency Guidelines For Corn Production In Arkansas Based On Tissue Analysis And Remote Sensing, Caio Luiz Dos Santos

Graduate Theses and Dissertations

There are a lack of tools to assess midseason nitrogen (N) status in corn (Zea mays L.) production systems and identify the need for additional N fertilization. This study was conducted to determine the ability of leaf N concentration (LN) and the Dark Green Color Index (DGCI) at the 10th collared leaf stage (V10), the 12th collared leaf stage (V12), and tasseling (VT) to predict if midseason N is required to maximize corn grain yield. From 2017 to 2019, eight field studies with 11 N treatments ranging from 0 to 258 kg N ha-1 were conducted on silt loam soils …

Born-Again On Sundays: Exploring Narratives Of Belief And Performances In A Belizean Methodist Church, Katharine Serio

Graduate Theses and Dissertations

If you are only at church services on Sunday and do not actively practice your religious faith every day, are you “born again” every day? Reverend Rebecca Lewis of Wesley Methodist Church in a small town in Belize preaches active participation in the church and encourages her congregation to attend all religious events, pray rigorously, and read the Bible actively, but how does the congregation listen to her and react to her sermons? “Born-Again on Sundays” is an ethnographic account that draws on anthropological theories of belief and vernacular religion, performance and narrative, and poverty and reflexivity to explore the …

Lesioning Of The Nucleus Of The Hippocampal Commissure Followed By Food Deprivation Stress In Birds Demonstrates Simultaneous Involvement In Both The Hypothalamo-Pituitary-Adrenal Axis And The Hypothalamo-Pituitary-Thyroid Axis, Michael Thomas Kidd Jr.

Graduate Theses and Dissertations

The hypothalamo-pituitary-adrenal (HPA) axis is the regulatory system for the neuroendocrine stress response within vertebrates. Within the HPA axis corticotropin releasing hormone (CRH) is a major regulator and driving hormone. A structure named the nucleus of the hippocampal commissure (NHpC) has been found to contain CRH neurons and also these neurons respond to early food deprivation stress significantly prior to the paraventricular nucleus (PVN), the major driving nucleus of the classic neuroendocrine HPA axis. The objective of this study was to perform a knock down of the NHpC via electrolytic lesioning, thus eliminating a significant portion of its population of …

The Effects Of Auditory And Olfactory Cues On Visual Attention Toward Food Images Under Acute Stress, Reza Moltaji

Graduate Theses and Dissertations

Psychological stress has been shown to increase preference for high calorie foods containing high levels of sugar and fat. Since excessive intake of high calorie foods may increase potential risk of obesity and other relevant health issues, relieving psychological stress may help in maintaining a balanced diet and good health status. Although a variety of strategies for relieving psychological stress has been suggested, little attention has been paid to regarding whether such strategies can result in balanced diets. Since music therapy and aromatherapy have proven popular approaches to relieving psychological stress, this thesis aimed at determining whether listening to music …
