Characterization Of Carbon Nanotube/Polystyrene Composites Prepared Via Microwave-Induced Polymerization, Hubert Agamasu

College of Graduate Studies: Theses & Dissertations

Carbon nanotubes (CNTs), with their excellent mechanical properties, are well suited to the production of composites with good strength-to-weight ratio. However, the use of nanotubes as reinforcement is hampered by the lack of interaction between their inert surfaces and matrices. This, coupled with the van der Waal’s interactions between individual nanotubes, leads to agglomeration of CNTs in media. Functionalization is an efficient means to disperse nanotubes as well as increase their reactivity. The irradiation of CNTs with microwaves generates instantaneous, localized heating, being used in this work to trigger the rapid, thermal, free radical polymerization of styrene. Under microwaves, olefin-functionalized …

Detecting Bearing Race Defects With Inductive Magnetic Reluctance Sensors And Artificial Neural Networks, Collin Daly

College of Graduate Studies: Theses & Dissertations

This work proposes a method of detecting physical damage to bearing races in a rotational assembly by means of magnetic reluctance sensors generating a signal from a rotating gear-tooth wheel. A nominally sinusoidal signal is generated based on the rotation of a gearwheel with regularly spaced voids and lands. Detection is based on the time variance of the signal periodically in relation to the gearwheel and the bearing damage. The purpose of this work is to propose a process to detect and classify bearing race defects using existing sensors and neural networks for hazardous area equipment applications.

Development Of A Measure Assessing Adolescent Aggression: The Aggressive Behavior Risk Assessment- Adolescent- Parent Report (Abra-A-Pr), Katherine Fallon

College of Graduate Studies: Theses & Dissertations

Although parent-report scales for general behavioral difficulties and aggression (e.g., verbal and physical aggression) exist, there are currently no measures assessing sexual behaviors in this context. Commonly, parent-report measures provide a few items relevant to behavioral aggression, and items encompassing sexually aggressive behaviors are frequently vague and non-specific in the actions being committed by the adolescent. The primary purpose of this project was to develop a comprehensive and multifaceted parent-report measure for aggressive behavior in adolescents. Three separate studies were conducted to evaluate the psychometric properties of the measure. Exploratory (EFA) and confirmatory factor analysis (CFA) were used to investigate …

Examining The Moderating Effect Of Self-Compassion Between Rumination And Alcohol Use, Victoria Forgea Allen

College of Graduate Studies: Theses & Dissertations

Abundant research suggests alcohol use among college students as a public health concern (SAMHSA, 2014). Previous studies support rumination, a manner of responding to emotional distress which involves repetitively and passively focusing on the distress, is linked to problematic alcohol use among college students (Oswalt et al., 2020). On the other hand, not all college students who experience rumination engage in problematic alcohol use which suggests the presence of a moderating variable. Due to its emotion regulating abilities and positive associations to well-being, self-compassion may be on factor that affects the relationship between rumination and alcohol use (Diedrich et al., …

Development Of A Novel Measure To Assess For Alcohol Misuse In Older Adults: The Alcohol Misuse Scale For Older Adults (Amsoa), Nathan Jensen

Alcohol is the most regularly used intoxicating substance in most geographic locations. Alcohol use in the United States specifically is well over global averages. While alcohol misuse is generally considered to be understood as a problem for younger adults, it is often unrecognized and understudied older adult populations. Currently, there is an absence of a comprehensive tool measuring for developmentally salient behaviors, symptoms, and features of alcohol misuse in older adulthood, which blocks researchers’ ability to measure alcohol misuse well. The purpose of this study is to develop a psychometrically valid and reliable assessment of alcohol misuse for older adult …

Social Support In Black Individuals: The Moderating Effects On The Relationship Between Resilience And Well-Being, Imani Elise Crosby

College of Graduate Studies: Theses & Dissertations

Black individuals possess numerous strengths and positive contributions that build strong communities and cultivate psychological well-being (Biglan et al., 2012). However, much of the current literature focuses on hardships Black individuals face, skewing the larger discourse of their lived experience. This exclusive focus on adversity often neglects pathways by which Black people thrive and flourish. It is important to consider how Black experiences relate to a sense of well-being. Resilience, or the ability to “bounce back” from adverse experiences is linked well-being outcomes (APA, 2012). However, it is unknown whether the promotive effects of resilience directly contribute to well-being outcomes …

Functional Monitoring For Run-Time Assurance Of A Real-Time Cyber Physical System, Matthew W. Gelber

Mechanistic Analysis Of Four-Way Dna Junctions And Cytokine-Binding Aptamers For Therapeutic Interventions, Roaa S. Mahmoud

Theses and Dissertations

DNA is inherently dynamic and topologically diverse and can fold into many different structures. Besides the canonical Watson-Crick structure, other higher-order structures such as G-quadruplexes (G4), i-motifs (iM), and four-way DNA junctions are possible. Although these high-order DNA structures are known to form transiently, they are important due to the crucial roles they play in many cellular processes including DNA replication, recombination, and repair. Among these DNA structures, 4-way junctions (also known as Holliday junctions, HJ) which are formed during the repair of double-strand DNA breaks (DSBs) and interact with proteins have garnered significant attention due to their central role …
