Novel Patterns For Nucleosome Positioning: From In Vitro To In Vivo, David Andrew Bates
Novel Patterns For Nucleosome Positioning: From In Vitro To In Vivo, David Andrew Bates
Theses and Dissertations
The fundamental unit of chromatin is the nucleosome, which consists of a core of eight proteins wrapped by DNA. This core is composed of four pairs of histone proteins: H2A, H2B, H3, and H4. The DNA wraps around the protein core ~1.7 times, facilitating compaction of DNA length in the cell. Further, the location of nucleosomes makes genomic elements encoded in the DNA, such as promoters or enhancers, accessible or inaccessible to RNA polymerase and transcription factors. Thus, where nucleosomes are located (or positioned), can play a major role in transcription or other cellular processes. Additionally, histone proteins are frequently …

Voices From The Field: A Critical Incident Study Of Teachers' Perspectives On What Helps And Hinders The Implementation Of Behavior Intervention Plans In The Classroom, Emily Anne Cragun
Theses and Dissertations
Student problem behavior continues to be a major issue in schools for both teachers and students. Teachers often feel they are not provided with enough resources to help them manage this problem behavior. Students who engage in problem behavior tend to struggle socially and academically. When classified with an emotional disturbance, students are especially at risk due to the severity of the problem behavior they exhibit (Brauner & Stephens, 2006). This study examined how function-based interventions can help both teachers and students better manage the effects of problem behavior. There are several factors believed to hinder the effectiveness of function-based …

Localization Of Open Educational Resources By Facilitators Of A Human Rights Course In Ghana, Emily Durham Bradshaw
Localization Of Open Educational Resources By Facilitators Of A Human Rights Course In Ghana, Emily Durham Bradshaw
Theses and Dissertations
Research on the use of Open Educational Resources (OER) often notes the potential benefits for users to revise, reuse, and remix OER to localize it for specific learners. However, a gap in the literature exists in terms of research that explores how this localization occurs in practice. This is a significant gap given the current flow of OER from higher-income countries in the Global North to lower-income countries in the Global South (King et al., 2018). This study explores how OER from one area of the world is localized when it is used in a different cultural context. As part …
An Augmented Reality Maintenance Assistant With Real-Time Quality Inspection On Handheld Mobile Devices, James Thomas Frandsen
An Augmented Reality Maintenance Assistant With Real-Time Quality Inspection On Handheld Mobile Devices, James Thomas Frandsen
Theses and Dissertations
With the advances of industry 4.0, augmented reality (AR) devices are being deployed across the manufacturing sector to enhance worker perception and efficiency. AR is often used to deliver spatially relevant work instructions on mobile devices for maintenance procedures on the factory floor. In these situations, workers use their mobile devices to view instructions in the form of 3D animations and annotations that directly overlay the equipment being maintained. Workers then follow the AR instructions and must ultimately rely on their own judgement and knowledge of the procedure as they progress from step to step. An AR assistant that could …

Effects Of Microbial Transglutaminase On Gluten-Free Sourdough Bread Structure And Loaf Characteristics, Anna J. Redd
Theses and Dissertations
In an effort to mimic the continuous protein matrix found in gluten-containing breads, the effects of the enzyme microbial transglutaminase were tested in gluten-free (GF) sourdough breads containing five different GF flours: chickpea, brown rice, white rice, oat, and quinoa. The utilization of transglutaminase in GF sourdough bread applications was shown to improve some of the final bread characteristics of GF breads. White and brown rice GF sourdough loaves at 24 hours showed a 28% and 13% decrease in crumb firmness with the addition of 2 U/g dough, respectively. Quinoa-GF sourdough breads at 24 hours showed a 6% increase in …
Improving Spatial Resolution Of Time Reversal Focusing Using Arrays Of Acoustic Resonators, Adam David Kingsley
Improving Spatial Resolution Of Time Reversal Focusing Using Arrays Of Acoustic Resonators, Adam David Kingsley
Theses and Dissertations
Using a near-field array of acoustic resonators, it is possible to modify a focused pressure field and enforce a spatial frequency corresponding to the resonator array spacing. This higher spatial frequency makes it possible to focus and image with a resolution that is better than if the focusing were in free space. This near-field effect is caused by the phase shifting properties of resonators and, specifically, the delayed phase found in waves with a temporal frequency lower than that of the resonators in the array. Using time reversal, arrays of resonators are explored and the subwavelength focusing is used to …

We review various elements of missionary life, including the age of missionaries, religious pressures, pressures inherent in missionary life, and cultural naiveté. Each of these is tied to potential weaknesses in which emotional abuse can impact the life and relationships of a missionary. Suggestions for safeguards …
Friction Taper Plug Welding As A Repair Method For Fatigue Damage Around Fastener Holes In Aerospace Structures, David Carl Sumsion
Friction Taper Plug Welding As A Repair Method For Fatigue Damage Around Fastener Holes In Aerospace Structures, David Carl Sumsion
Theses and Dissertations
This work details an adaptation of the friction taper plug welding (FTPW) process to repair fatigue damage in 6.35mm AA 7050 t-7451 plate. Aircraft components experience fatigue damage around fastener holes. This damage can be mitigated by enlarging fastener holes. There is no effective repair procedure once holes reach a maximum allowable size. Damaged components must be replaced. A suitable repair process would lead to substantial savings in both time and money. A simulated repair process was developed by machining holes in 6.35mm AA 7050 t-7451 plate. These hoes were then plugged using the FTPW process. Microhardness testing and metallographic …
Focusing Of High-Amplitude Sound Waves Using The Time Reversal Process, Brian D. Patchett
Focusing Of High-Amplitude Sound Waves Using The Time Reversal Process, Brian D. Patchett
Theses and Dissertations
Time reversal is a method often used to focus sound to a desired location, and works best in a reverberant environment. The effect of focus location within a reverberant environment is presented first, revealing that proximity to reflecting surfaces has a significant effect on the amplitude of the focus both experimentally and when using a modal summation model. These effects are a primary component to creating focus signals at high amplitudes. High-amplitude focusing experiments show that when multiple sources are used simultaneously to generate a focus, a peak amplitude pressure spike of 200 dB can be achieved in air. A …

Methods For Engineers To Understand, Predict, And Influence The Social Impacts Of Engineered Products, Phillip Douglas Stevenson
Methods For Engineers To Understand, Predict, And Influence The Social Impacts Of Engineered Products, Phillip Douglas Stevenson
Theses and Dissertations
Engineered products can impact the day-to-day life of their users and other stakeholders. These impacts are often referred to as the product's social impacts. Products have been known to impact the people who use them, design them, manufacture them, distribute them, and the communities where they exist. Currently, there are few methods that can help an engineer identify, quantify, predict, or improve a product's social impact. Some companies and organizations have tried to identify their impacts and, for example, set goals for achieving more sustainable business practices. However, engineers, in large part, do not have methods that can help improve …

The Use Of Inertial Measurement Unit For The Characterization Of Multiple Functional Movement Patterns In Individuals With Chronic Ankle Instability, Seunguk Han
Theses and Dissertations
Patients with a history of lateral ankle sprain (LAS) may experience different levels of mechanical and/or sensorimotor deficits following their injuries. Although various factors, such as structural damage, sensorimotor adaptation, perceived instability, swelling and/or pain, can develop and perpetuate the condition of chronic ankle instability (CAI), most previous CAI research on biomechanics has considered all patients with CAI as a homogeneous group. Recent research has clustered patients with CAI into six distinct movement patterns during a maximal jump-landing/cutting task. This approach could motivate clinicians to develop appropriate rehabilitation programs for each patient with CAI depending on their movement patterns. However, …

Audience And Mockingbird: A Narrator's Guide, Charisse Baxter
Audience And Mockingbird: A Narrator's Guide, Charisse Baxter
Theses and Dissertations
While adaptation research possesses longstanding applications and ample material for study, seldom has a data set proven to be as iconic and culturally relevant as the various iterations of To Kill a Mockingbird. Novel to film to stage play, and then nearly 60 years later to a second stage play, the story has resonated with audiences in a range of performative variations. A defining characteristic of Harper Lee's tale is her use of a narrator; this characteristic provides an effective entry-point in examining the two stage adaptations by way of their interpretation of the narrator. A study of the respective …
Critical Race Theory, Natural Rights, And The Fate Of Liberalism, Landon Hooley
Critical Race Theory, Natural Rights, And The Fate Of Liberalism, Landon Hooley
Undergraduate Honors Theses
Is critical race theory compatible with liberalism? I argue that it is not, and that natural rights theory, liberalism's rational core, ought to be preferred as the primary framework to create public policy and understand the law. Critical race theory (CRT) has outgrown its original design as a legal critique and become a political worldview, although it is not developed enough to constitute an ideology or philosophy. It has inspired various organizations and movements that expand upon its principles and propose ideals and policies that conflict with the current constitutional liberal order. Many conflicts between natural rights theory and critical …

Historical And Recent Breeding Of The Western Grebe And Clark's Grebe In A Severely Impaired Ecosystem At Clear Lake, California, Floyd E. Hayes, Bryan J. Mcintosh, Dylan G. Turner, Douglas E. Weidemann
Monographs of the Western North American Naturalist
Clear Lake is a large (176.7-km2) natural lake in northern California, USA. An estimated 1000 pairs of Western Grebes (Aechmophorus occidentalis) and Clark’s Grebes (A. clarkii) nested on the lake prior to massive applications of the pesticide dichlorodiphenyldichloroethane (DDD) to kill the Clear Lake gnat (Chaoborus astictopus) during 1949–1957. Biomagnification of DDD was implicated as the cause of several mass mortality events of grebes and short-term reproductive failure in the 1950s, although other factors such as mercury (Hg) poisoning may have contributed. Successful nesting resumed in 1960 and increased gradually, with up …

Transforming Gps Points To Daily Activities Using Simultaneously Optimized Dbscan-Te Parameters, Gillian Michele Riches
Transforming Gps Points To Daily Activities Using Simultaneously Optimized Dbscan-Te Parameters, Gillian Michele Riches
Theses and Dissertations
With the recent upsurge in mental health concerns and ongoing isolation regulations brought about by the COVID-19 pandemic, it is important to understand how an individual's daily travel behavior can affect their mental health. Before finding any correlations to mental health, researchers must first have individual travel behavior information: an accurate number of activities and locations of those activities. One way to obtain daily travel behavior information is through the interpretation of cellular Global Positioning System (GPS) data. Previous methods that interpret GPS data into travel behavior information have limitations. Specifically, rule-based algorithms are structured around subjective rule-based tests, clustering …
Are Changes In Muscle Blood Flow Associated With The Age-Related Decrease In Critical Power?, Abigail Dorff
Are Changes In Muscle Blood Flow Associated With The Age-Related Decrease In Critical Power?, Abigail Dorff
Theses and Dissertations
Aging results in lower exercise tolerance, manifested as decreased Critical Power (PCRIT). Aging is also associated with reduced physical activity, decreased muscle mass, and altered muscle blood flow, all of which may contribute to the age-related decrease in PCRIT. Purpose: The purpose of this study was to determine if the age-related decrease in PCRIT occurs independently of changes in physical activity and muscle mass and if it is related to impaired muscle blood flow. Methods: 10 Old (63.1 ± 2.5 years, 5 female and 5 male) and 10 Young (24.4 ± 4.0 years, 5 female and 5 male) physically active …
Forecasting Ride-Hailing Across Multiple Model Frameworks, Christopher Stephen Day
Forecasting Ride-Hailing Across Multiple Model Frameworks, Christopher Stephen Day
Theses and Dissertations
The advent of on-demand transport modes such as ride-hailing and microtransit has challenged forecasters to develop new methods of forecasting the use and impacts of such modes. In particular, there is some professional disagreement about the relative role of activity-based transportation behavior models -- which have detailed understanding of the person making a trip and its purpose -- and multi-agent demand simulations which may have a better understanding of the availability and service characteristics of on-demand services. A particular question surrounds how the relative strengths of these two approaches might be successfully paired in practice. Using daily plans generated by …
An Investigation Into The Role Of Geometrically Necessary Dislocations In Multi-Strain Path Deformation In Automotive Sheet Alloys, Rishabh Sharma
An Investigation Into The Role Of Geometrically Necessary Dislocations In Multi-Strain Path Deformation In Automotive Sheet Alloys, Rishabh Sharma
Theses and Dissertations
Multiple strain path changes during forming lead to complex geometrically necessary dislocation (GND) development in strain gradient fields, inducing internal stresses that contribute to the Bauschinger effect, residual stresses, and springback which alters the final geometrical shape of the part. In order to analyze and design improved processing routes, models must capture the evolution of these internal stresses. However, most models capture the effects of these stresses via phenomenological approaches that require calibration to each new material and strain path. The development of models that capture the underlying physics at the sub-grain level is underway but requires in-depth studies of …
