Starch Granule And Crystalline Structures With Relation To Enzyme Digestibility, Ana Isabel Gonzalez Conde
Starch Granule And Crystalline Structures With Relation To Enzyme Digestibility, Ana Isabel Gonzalez Conde
Graduate Theses and Dissertations
Porous starch produced by enzyme hydrolysis has attracted much attention for its adsorption and delivery properties. Porous starch has been successfully prepared from A-type starch, but not from B-type and C-type starches, which is partly attributed to the surface and crystalline structure. The present study aimed to characterize the role of the crystalline structure and the structure-function relationship impacting the susceptibility of starch with different crystalline polymorphs to amylase digestion. The starches were subjected to chemical modification (acid hydrolysis or surface gelatinization), physical modification (heat-moisture treatment, HMT, or high-pressure processing, HPP) or their combinations prior to amylase digestion, and the …
The Relationship Between Upper Body Muscular Power And Objectively Measured Physical Function In Healthy Older Adults, Jordan Stroope
The Relationship Between Upper Body Muscular Power And Objectively Measured Physical Function In Healthy Older Adults, Jordan Stroope
Graduate Theses and Dissertations
The population of older adults is growing rapidly worldwide. There are significant challenges associated with an aging population, many of which are related to declining physical function. Muscular power has previously been postulated as an important physical characteristic for preserving physical function, however, much of the research has measured lower body muscular power against functional outcomes. The importance of upper body muscular power (UBMP) for physical function outcomes is less clear, thus, this study sought to examine that relationship. Forty-two older adults between the ages of 50 – 70 (avg = 60.5 years 5.7) were recruited for the current …

The Silence In America’S Classrooms: The Portrayal Of Women And Gender In United States High School History Textbooks, Allie Elizabeth Morris
The Silence In America’S Classrooms: The Portrayal Of Women And Gender In United States High School History Textbooks, Allie Elizabeth Morris
Graduate Theses and Dissertations
In the twenty-first century, the process of adopting statewide history textbooks has become a political battleground surrounding concepts of race, gender, and identity in American history. By contextualizing the current discussion surrounding content in American history textbooks, I examine the portrayal of women in secondary United States social studies textbooks from the 1960s to the 2010s. In doing so, I show how portrayals of women's history evolve in the most widely adopted high school post-Civil War American history textbooks in each decade from the 1960s through to the 2000s. By comparing the evolution of the women’s and gender historiography to …
A Geospatial Assessment Of Turkey’S Military Campaigns Against The Autonomous Administration Of North And East Syria, Steven Lucas Escalante
A Geospatial Assessment Of Turkey’S Military Campaigns Against The Autonomous Administration Of North And East Syria, Steven Lucas Escalante
Graduate Theses and Dissertations
In addition to hosting more Syrian refugees than any other nation, Turkey has played a significant role in the dynamics of the Syrian civil war since 2011 under President Recep Tayyip Erdoğan. As the dynamics in the war shifted, so did Ankara’s focus towards the preferred ground forces of the Global Coalition for the fight against the Islamic State, who Ankara views as an extension of the PKK. In turn, this PYD-led de-facto Autonomous Administration has faced multiple Turkish ground invasions since 2016 and a continuing series of aerial attacks. A geospatial assessment of the Turkish-Syrian Democratic Forces border conflict …

Microorganisms In Extreme Environmental Conditions, Khanh Mai Nguyen
Microorganisms In Extreme Environmental Conditions, Khanh Mai Nguyen
Graduate Theses and Dissertations
Organisms are known to be able to prosper under normal and extreme environmental conditions, which are classified as mesophile and extremophile, respectively. Extremophiles can thrive under a large array of conditions, from pressures, temperatures, salinity, and pH to a combination of them. For example, to survive on the ocean floor, marine biomass must have its biomolecular machinery adapted to the high pressures and high salinity environment. Moreover, around the hydrothermal vents, aside from pressure and salinity, the microbes that live there also need to adjust to the temperature as well as the pH level. Aside from high temperatures, researchers also …
Investigation The Plugging Behavior Of Virus Filters, Iman Abdulqader Saab
Investigation The Plugging Behavior Of Virus Filters, Iman Abdulqader Saab
Graduate Theses and Dissertations
A virus filtration step is integral to the manufacturing of biopharmaceuticals to ensure viral safety. A virus filter is a single-use device that uses a size-based separation process and has a unique structure with minimal defects, so that contaminating virus particles cannot pass through the membrane pores, while therapeutic molecules can. The development of novel antibodies (Abs), including significant increases in product titers, is frequently challenged by virus filter fouling, making a better understanding of the underlying mechanisms essential. This thesis focused investigating of the effect of prefilter types, buffer type and salt content on virus filtration performance. The impact …

Graduate Theses and Dissertations
Cnidaria (i.e., sea anemones, jellyfish, corals) and Bilateria (i.e., vertebrates, sea stars, fruit flies), are sister groups that diverged around 600 million years ago. Despite the long evolutionary time, many cellular differentiation mechanisms, cell types, tissues and behaviors are conserved. Such as neurons, mechanosensory hair cells, feeding behaviors, peristaltic movements, and sleep. Recent advances in genomics, molecular biology and microscopy have fueled an increased interest in understanding cnidarian nervous and neuroendocrine systems. Understanding the developmental mechanisms and the mode of operation of Cnidarian nervous systems helps to reconstruct the ancestral nervous system of the last common ancestor of Cnidaria and …

Multiomic Explorations Of Fruit Texture And Postharvest Quality In Blackberry And Muscadine Grape, Thomas Mason Chizk
Graduate Theses and Dissertations
For most fresh-market fruit crops, texture is an important trait that strongly affects both shipping potential and consumer opinion. Efficient, scalable phenotyping methods are required by breeding programs to effectively select for improvements to fruit texture quality. In muscadine, we have developed a recommendation for characterizing complex muscadine grape texture profiles by comparing the results of breeders’ ratings, descriptive sensory panel results, and an array of instrumental protocols. Regression models were constructed to predict awareness of skins, crispness, hardness, and visual separation explaining 85%, 91%, 82%, and 83% of variance respectively. Genotypes that scored most highly in breeders’ ratings of …
Class Salient Interactions And Selection Decisions: The Stratifying Power Of Employers’ Emotions, Kristie Moergen
Class Salient Interactions And Selection Decisions: The Stratifying Power Of Employers’ Emotions, Kristie Moergen
Graduate Theses and Dissertations
Securing employment is critical to accessing labor market rewards such as a steady income, benefits, and advancement opportunities. However, an individual's social class—corresponding with their economic, social, and cultural capital—may advantage or disadvantage them in gaining employment. Indeed, it is well-evidenced that the lower social class experiences labor market disadvantage, and management scholars point to organizational selection processes as one lever of such inequality. Still, the role of class salient interactions—same- and cross-class interactions between an interviewer and interviewee— and, specifically, the role of the employer remains an open question. Understanding how class salient interactions impact selection is critical, not …

Anatomy 101 (A Mysterium) Revelations On Process, Sarah Dianne Loucks
Graduate Theses and Dissertations
I came to graduate school thinking all I needed to become a stronger writer was an understanding of craft and technique. To my dismay, I discovered that craft and technique, while helpful and important, are not magic bullets. Instead, I discovered that the main obstacle to my growth as a writer is my own self. This thesis discusses my battle with perfectionism and fear of the unknown in the context of writing my thesis play, Anatomy 101 (A Mysterium), and the subsequent production that occurred at The Global Campus Theatre in Fayetteville, AR in March of 2023.

Investigating Effect Of Seed Source And Developing Germination Protocols To Improve Success In Restoration Of Arkansas Tallgrass Prairies, Rhiannon Spencerosa
Graduate Theses and Dissertations
American tallgrass prairie has faced losses estimated at 87-98% of original land area since European settlement. Native seeds are often used to supplement struggling or extinct plant populations in tallgrass prairie restoration and establishment sites. Two main considerations in restoration and establishment are from where to source seed and how to obtain high germination rates. In order to determine the effect of seed source, a common garden experiment was performed in Fayetteville, Arkansas in 2022 with five prairie species: Andropogon gerardii (big bluestem), Bouteloua curtipendula (sideoats grama), Panicum virgatum (switchgrass), Schizachyrium scoparium (little bluestem), and Sorghastrum nutans (Indiangrass). Seed was …
