The Immediate Effects Of The Nunee Patellar Support On Individuals With Patellofemoral Pain Syndrome, Nick Linn

Graduate Theses, Dissertations, and Problem Reports (ETD)

Patellofemoral pain syndrome (PFPS) is a common form of anterior knee pain caused by general overuse, muscular weakness or strength imbalances, and poor movement coordination leading to abnormal alignment or mal-tracking of the patella. Recent guidelines do not recommend the use of a knee orthosis due to a lack of evidence supporting their effectiveness. A new patellar support (NuNee, K-Neesio LLC.) which uses distraction force to relieve pressure placed on the patella, has been proposed. The purpose of this study was to examine the immediate effects of the NuNee patellar support on perceived pain, biomechanics, and function in individuals with …

Essays In Applied Microeconomics, Joshua C. Martin

Graduate Theses, Dissertations, and Problem Reports (ETD)

The first chapter examines the role that same-sex marriage legalization had on the number of adoptions of children from foster care in the United States. We do so by employing a synthetic difference-in-differences estimator which leverages both the differential timing of these laws across states and the subsequent wave of state-level legal protections which give foster-care agencies the right to deny service to same-sex couples based on religiously-held beliefs. Using highly detailed, county-level data of nearly 20 million children in the foster care system from 1995-2020, our findings reveal that same-sex marriage legalization led to a 3.8%-5.9% increase in the …

Abstract

Comparison of Skeletal Class III Malocclusion Facial-Shape Subtypes Between

Caucasian, African American, and Hispanic Populations

Rachel K. Huffman, DMD

Introduction: The development of a skeletal Class III malocclusion (Cl III) is complex as it can arise from the overgrowth of the mandible, undergrowth of the maxilla, or a combination of the two. To understand the heterogeneity of this trait clinically, studies have been conducted using facial shape analysis (e.g., Geometric morphometrics (GeoMorph)) of Caucasian and Asian populations to learn more about the principal shapes. Little is known, however, about the predominant principal shape components of Cl III within African …

Elucidation Of The Role Of Agouti-Signaling Protein Throughout Folliculogenesis And Early Embryonic Development In Cattle, Heather L. Chaney

Graduate Theses, Dissertations, and Problem Reports (ETD)

The oocyte expresses certain genes during folliculogenesis to regulate the acquisition of oocyte competence. Oocyte competence, which refers to the presence of imperative molecular factors in the oocyte that are critical for high oocyte quality, is directly related to the ability of the oocyte to result in a successful pregnancy following fertilization. Over the past few decades, the development and optimization of assisted reproductive technologies, particularly in vitrofertilization, have enabled the beef and dairy industries to advance cattle genetics and productivity. However, only approximately 40% of bovine embryos will develop to the blastocyst stage in vitro. In addition, bovine embryos …

Gender Inclusivity In Italian: Can Gender Neutrality Be Reached In A Gendered Language? Difficulties, Proposals And Public Perception Of The Phenomenon, Gaia Prunotto

Graduate Theses, Dissertations, and Problem Reports (ETD)

Italian is a gendered language in which reference to grammatical gender has been constant and inevitable. As language reflects and shapes society, grammatical gender reinforces binary views of social gender and the invizibilization of non-binary identities. Movements for social justice have inspired gender-fair linguistic innovations, such as the feminization of job titles and gender-neutral markers, to promote gender equity and challenge hierarchies of power and dominance in society. This research aimed to explore gender-neutral forms in the Italian grammatical system and public perceptions of these innovations through two studies with two groups of participants.

The first group of participants (n=27) …

Longitudinal Oxygen Imaging In 3d (Bio)Printed Models, Ryan Curtis O'Connell

Graduate Theses, Dissertations, and Problem Reports (ETD)

Electron paramagnetic resonance (EPR), and its molecular imaging modality, is a powerful tool to noninvasively map various biological and chemical markers within objects of interest. Reliable data acquisition is a major impeding factor for longitudinal hands-off measurements. Measurements are especially challenging in biomedical applications, as live objects are not static. Frequent changes occur that require constant fine recalibration of the EPR detection system, called the resonator. To enable longitudinal imaging, a technology permitting automatic digital control of resonator coupling, tuning, and EPR data acquisition was developed. Automation was achieved through the utilization of a microcontroller and digital peripheral components such …

Evaluating Innovative Methods Of Quantitatively Linking Microbial Community Structure To Ecosystem Function, Jeth Gv Walkup

Graduate Theses, Dissertations, and Problem Reports (ETD)

Microbial functional diversity is the product of community structure and intraspecific trait variation. Due to microbial diversity and limited availability of microbial trait measurements, it has been challenging to quantitatively link community structure to microbial function. Although community-level activity rates vary with community composition, issues in the scale of their measurement inhibit our understanding of their relationship. Quantitative stable isotope probing (qSIP) is a method for quantitatively measuring taxon-specific microbial traits, providing new opportunities to apply trait-based approaches for studying microbial ecology. Quantitative microbial trait data from these experiments enables the functional characterization of microbial communities, potentially enabling the extrapolation …

A Randomized Controlled Trial Comparing Pcit-Toddler, Circle Of Security, And Waitlist Controls To Improve Child And Caregiver Emotion Regulation, Robin Choi Han

Graduate Theses, Dissertations, and Problem Reports (ETD)

Emotion regulation is an important developmental task during toddlerhood that is associated with positive psychosocial outcomes (Zeman et al., 2006). The development of adaptive emotion regulation during early childhood occurs largely within the context of a supportive caregiver-child relationship (Morris et al., 2007). Thus, parent-mediated interventions are a promising medium through which emotion regulation problems in toddlers can be treated. However, few interventions specifically designed to treat behavioral and emotion regulation difficulties are available for children in the toddler age range, and these interventions have yet to establish a solid evidence base supporting their efficacy. To fill this gap in …

State Estimation, Covariance Estimation, And Economic Optimization Of Semi-Batch Bioprocesses, Ronald Hunter Alexander

Graduate Theses, Dissertations, and Problem Reports (ETD)

One of the most critical aspects of any chemical process engineer is the ability to gather, analyze, and trust incoming process data as it is often required in control and process monitoring applications. In real processes, online data can be unreliable due to factors such as poor tuning, calibration drift, or mechanical drift. Outside of these sources of noise, it may not be economically viable to directly measure all process states of interest (e.g., component concentrations). While process models can help validate incoming process data, models are often subject to plant-model mismatches, unmodeled disturbances, or lack enough detail to track …

Producing Hardwood Cross - Laminated Timber (Hclt) Mats From Low Grade Red Oak Lumber, Jonathan R. Norris

Graduate Theses, Dissertations, and Problem Reports (ETD)

The use of cross-laminated timber (CLT) has significantly grown in North America, but hardwood species have not yet been deemed a viable material to manufacture CLT panels, whereas, softwood species continue to serve as the only approved material for CLT in structural applications according to ANSI/APA PRG-320. In order to introduce hardwoods into the CLT market, we must develop non-structural CLT products that utilize low grade lumber from hardwood species.

Use Of Carbonation For Treatment Of Coal Mine Drainage To Increase Limestone Dissolution And Generate Alkalinity, Dietrich Henry Kuhlmann Iv

Graduate Theses, Dissertations, and Problem Reports (ETD)

Abstract

Use of Carbonation for Treatment of Coal Mine Drainage to Increase Limestone Dissolution and Generate Alkalinity

Dietrich Kuhlmann IV

Anoxic limestone drains (ALDs) are a common component used within passive treatment systems for coal mine drainage (CMD). Contact between limestone aggregate and CMD results in limestone dissolution, producing carbonate alkalinity. Though ALDs are one of the least expensive CMD treatment technologies, alkalinity generation is limited by limestone solubility. This necessitates a long retention time (>12 hours) and sometimes results in net acidic effluent which requires additional alkalinity generation steps downstream. One way to increase calcite dissolution and alkalinity …

A Comparative Analysis Of Coastdown Testing Methods From An Electric Drive Unit Engagement Perspective Using A Student-Designed Parallel Hybrid Electric Vehicle, Dawson Everett Dunnuck

Graduate Theses, Dissertations, and Problem Reports (ETD)

Coastdown testing and road load determination are pivotal parts of the automotive design process. Vehicle manufacturers and independent companies perform and analyze road loads determined through a coastdown or similar method to determine a vehicle’s road load for modeling and EPA certification. For a traditional coastdown, the vehicle’s drivetrain must be disconnected through a clutch between the engine and the transmission while traveling at a high rate of speed to place the vehicle in neutral. This changes for hybrid and electric vehicles. Some hybrid, and most electric, vehicles delivered to customers do not have this clutch action to grant the …

Localized Delivery Of Gm-Csf In The Regulation Of Breast Tumor Oxygen And Anti-Tumor Immunity Through Macrophages, Nicole E. Mihalik

Graduate Theses, Dissertations, and Problem Reports (ETD)

GM-CSF has been employed as an adjuvant to cancer immunotherapies in solid tumors due to its ability to drive immune stimulatory macrophages and other myeloid cells that promote anti-tumor responses. However, GM-CSF does not always exert immune stimulatory effects on myeloid cells, and sometimes even drives immune suppressive phenotypes. GM-CSF effects on myeloid cells and the tumor microenvironment (TME) appear to vary across dosages and even cancer types. However, an optimal dosing regimen for GM-CSF has yet to be determined to-date, and this is further complicated by the fact that GM-CSF is often administered via oncolytic viruses or tumor vaccines …

The Uncertain Future Of Landscapes Subjected To Mountaintop Removal Mining, Samuel James Bower

Graduate Theses, Dissertations, and Problem Reports (ETD)

Increased erosion following human land disturbance is a global issue for ecosystem health and land management. Mountaintop removal (MTR) mining – a type of surface mining predominately found in the Central Appalachian Coalfields region – is one of the most significant examples of human perturbation to a natural landscape. A post-MTR landscape, when compared to its natural state, has significantly different erosive potential due to the rearrangement of topography from mining and reclamation practices. Removal of vegetation and alterations to soil further influence erosion by raising the effective erodibility of substrate subjected to MTR. We quantify the changes in erosion …
