The Effects Of Ceria Addition On Aging And Sulfation Of Lean Nox Traps For Stand Alone And Lnt-Scr Applications, Vencon G. Easterling

Theses and Dissertations--Chemical and Materials Engineering

THE EFFECTS OF CERIA ADDITION ON AGING AND SULFATION OF LEAN NO_x TRAPS FOR STAND ALONE AND LNT-SCR APPLICATIONS

Model powder and fully formulated monolithic lean NO_x trap (LNT) catalysts were used to investigate the effect of ceria on desulfation behavior. Temperature-programmed reduction (TPR) experiments (model catalysts) showed each of the oxide phases present is able to store sulfur and possesses distinct behavior (temperature at which desulfation occurs). La-CeO₂ or CeO₂-ZrO₂-containing samples (monoliths) showed a greater resistance to deactivation during sulfation and required lower temperatures to restore the NO_x storage efficiency to …

Influence Of Surface Modification On Properties And Applications Of Complex Engineered Nanoparticles, Binghui Wang

Theses and Dissertations--Chemical and Materials Engineering

Complex engineered nanoparticles (CENPs) are being used on various applications. Their properties are different from those of neat nanoparticles. The dissertation explores these differences from four aspects: 1) Modify carbon nanomaterials’ inert surfaces and investigate the effect on thermal and rheological behavior of their dispersions; 2) Generate self-assembly bi-layer structure of oxide nanoparticles via surface modification; 3) Study interaction between lysozyme and different surface-charged ceria nanoparticles; 4) Investigate the biodistribution and transformations of CENPs in biological media.

An environment-friendly surface modification was developed to modify surfaces of carbon nanomaterials for increasing their affinity to non-polar fluid. It can offset formation …

Electromechanical Interaction On The Deformation Behavior Of Metallic Materials, Guangfeng Zhao

Theses and Dissertations--Chemical and Materials Engineering

Metallic materials play important roles in providing electrical, thermal, and mechanical functions in electronic devices and systems. The understanding of the electrical-thermal-mechanical interaction caused by the passage of electric current with high density is important to improve the performance and reliability of electronic assembly and packaging. The electromechanical interaction on the deformation behavior of copper and tin is studied in this work.

The electromechanical response of Cu strips was studied by passing a DC electric current. The electric resistance linearly increased with time before the occurrence of electric fusing. The electrothermal interaction led to the buckling of the Cu strips …

Transforming Domestic Violence Representation, Jane K. Stoever

Kentucky Law Journal

The dominant theories used in the law to explain domestic violence, namely, the Power and Control Wheel and the Cycle of Violence, provide only limited insight into intimate partner abuse. Both theories focus exclusively on the abusive partner' wrongful actions, consistent with recent decades' concentration on criminalization, but fail to educate about the survivor's needs and efforts to end violence. The Stages of Change Model, conversely, reveals that domestic abuse survivors seek an end to relationship violence through a five-stage cyclical sequence and identifies the survivor's needs and actions at each stage. This critical information should inform the representation of …

The Dsm-5 Dimensional Trait Model And The Five Factor Model, Whitney L. Gore

Theses and Dissertations--Psychology

The current thesis tests empirically the relationship of the dimensional trait model proposed for the fifth edition of the American Psychiatric Association’s (APA) Diagnostic and Statistical Manual of Mental Disorders with five-factor models (FFM) of personality disorder (PD). The DSM-5 Personality and Personality Disorders Work Group proposes to diagnose the disorders largely in terms of a 25 trait dimensional model organized within five broad domains (i.e., negative affectivity, detachment, antagonism, disinhibition, and psychoticism). Consistent with the authors of DSM-5, it was predicted that negative affectivity would align with FFM neuroticism, detachment with FFM introversion, antagonism with FFM antagonism, disinhibition with …

Reinforcing, Subjective, And Cognitive Effects Of Methamphetamine During D-Amphetamine Maintenance, Erika Pike

Theses and Dissertations--Psychology

Translational research suggests that agonist replacement may be a viable treatment approach for managing methamphetamine dependence. This study sought to determine the effects of d-amphetamine maintenance on methamphetamine self-administration in stimulant using participants. A cognitive battery was used to determine the performance effects of methamphetamine alone and during d-amphetamine maintenance. During each maintenance condition, participants first sampled a dose of intranasal methamphetamine then had the opportunity to respond on a progressive ratio task to earn portions of the sampled dose. Subject-rated drug-effect and physiological measures were completed prior to and after sampling methamphetamine. Methamphetamine was self-administered as function …

Emotion Recognition And Social Functioning In Children With And Without Attention Deficit Hyperactivity Disorder, Rebecca Flake Aldea

Theses and Dissertations--Psychology

This study examined the emotion recognition of children (ages 7-9 years) with and without Attention Deficit Hyperactivity Disorder (ADHD). Children completed two emotion recognition measures, the Diagnostic Analysis of Nonverbal Accuracy 2 (DANVA2) and the Child and Adolescent Social Perception measure (CASP). Children and their parents also completed an assessment of children’s social skills, the Social Skills Improvement System (SSIS). Children with ADHD reported a significantly greater level of depressive symptoms and had significantly lower full scale IQ scores than children without ADHD. When these differences were accounted for, children with ADHD continued to show a handful …

Examining The Interaction Of Neonatal Alcohol And Hypoxia In Vitro, Megan L. Carter

Theses and Dissertations--Psychology

Exposure to ethanol (ETOH) during fetal development results in a range of cognitive/behavioral deficits. There are differences in sensitivity to the effects of ETOH that could be explained by other factors, such as hypoxia. Similar mechanisms of damage underlie both ETOH, more specifically ETOH withdrawal, and hypoxia. Based on this overlap, it was hypothesized that sub threshold levels of these insults may interact to produce increased damage in sensitive brain regions. This study used a rodent organotypic hippocampal slice culture model to investigate the interaction of hypoxia and ETOH withdrawal and to determine possible developmental differences in the sensitivity to …

The Impact Of Religiosity Dimensions And Ethnic Identity On Well-Being In African American Women, Ebony S. Vinson

Theses and Dissertations--Psychology

Religiosity is considered to be an important component of the cultural orientation and worldview of African Americans. African American women, in particular, have been found to be unique in their level of religious devotion and activity compared to other demographic groups but there has been minimal research examining the positive effects of religiosity over time. The purpose of the current study was to investigate the role of religiosity dimensions and ethnic identity in predicting self-esteem, social support, healthy behaviors, and licit drug use in African American women over time. Results indicate that behavioral and cognitive components of religiosity predict different …

Development And Validation Of A Measure Of Self-Critical Rumination, Laura M. Smart

Theses and Dissertations--Psychology

Shame and self-criticism are closely related constructs that have strong associations with many forms of psychopathology as well as general psychological distress. Rumination is a maladaptive form of repetitive thinking that is associated with a number of psychological disorders. Although measures of many different types of rumination (e.g. depressive rumination, angry rumination) have been developed, none assess self-critical rumination. The purpose of the present study, therefore, was to develop a measure of self-critical rumination. An initial pool of items for the Self-Critical Rumination Scale (SCRS) was developed by adapting existing rumination measures and through a writing task administered to both …

Bayesian Analysis Of Parental Drinking Motives And Children's Adjustment, Aaron A. Duke

Theses and Dissertations--Psychology

Harm reduction strategies can mitigate against some of the deleterious effects of alcohol on families. These strategies are most feasible and cost-effective when they can be targeted at those who are most at risk. Previous studies examining the relation between parents’ alcohol use and their children’s psychological adjustment have failed to consider important contextual questions such as drinking motives. The current investigation set out to identify the extent to which parents’ drinking motives predict internalizing and externalizing psychopathology in their children. The investigation consisted of cross sectional analysis of parents’ drinking motives and their children’s adjustment using data from 154 …

The Impact Of Acculturation And Labeling On African Americans' Stigmatization Of Mental Illness, Tahirah Abdullah

Theses and Dissertations--Psychology

Although African Americans endorse more stigma towards those with mental illnesses than European Americans and are quite susceptible to stigma’s detrimental effects on help-seeking for mental health problems, stigma has not been adequately studied for African Americans. Given that stigma is a key barrier to obtaining help for mental health problems, it is imperative that we gain a more nuanced understanding of stigma. This study used experimental design and vignettes to examine the influence of acculturation and labeling on African Americans’ stigmatization of depression, social phobia, alcohol dependence, and schizophrenia. Results indicated that schizophrenia was generally the most stigmatized disorder …

Does Botox Buffer The Negative Effects Of Social Rejection?: A Test Of The Facial Feedback Hypothesis, Vicki Sharif

Theses and Dissertations--Psychology

Can a common facial cosmetic procedure buffer against the negative impact of adverse social interactions? This pilot tested the hypothesis that an injection of botulinum toxin (Botox) to the corrugator supercilii muscles used in anger, compared to a placebo injection to the same location, will reduce the impact of social rejection on mood, self-esteem, control, meaningful existence, and aggression. Freezing facial musculature was hypothesized to alter the first physical signal of negative emotional reactions, thereby reducing the impact of social rejection on distress and aggression. This was the first study using Botox to examine the effects of reduced facial feedback …

Expression Of Borderline Personality Disorder Symptoms Across The Ovulatory Cycle: A Multilevel Investigation, Tory A. Eisenlohr-Moul

Theses and Dissertations--Psychology

Borderline Personality Disorder (BPD) is a disabling condition characterized by chronic emotion dysregulation and behavioral impulsivity. Prospective studies that test proposed mechanisms of within-person change in BPD hold the key to improving symptom predictability and control in this disorder. A small body of evidence suggests that fluctuations in estradiol such as those occurring naturally at ovulation during the monthly female reproductive cycle may increase symptoms in women with BPD (DeSoto et al., 2003). Furthermore, there is preliminary evidence that both self-esteem and feelings of social rejection are highest at ovulation, when estradiol peaks (Durante and Hill, 2009; Eisenlohr-Moul et al., …

The Mesocorticolimbic Dopamine Pathway Reconstituted In Vitro: Glutamate Receptors And Corticosteroid-Methamphetamine Neurotoxicity, Jennifer N. Berry

Theses and Dissertations--Psychology

Stress promotes the use of methamphetamine and other recreational substances and is often implicated in relapse to stimulant use. Thus, it is of critical importance to examine the consequences of the co-occurance of stress and methamphetamine use. Activity of the glutamatergic N-methyl D-aspartate (NMDA) receptor system appears to be involved in the neurotoxic effects of both chronic stress and methamphetamine exposure. The current studies investigated the hypothesis that chronic pre-exposure to the stress hormone corticosterone (CORT) results in an increase of NMDA receptor activity and that this will potentiate the neurotoxic effects of methamphetamine (METH). Co-cultures of the …

The Effects Of Posttraumatic Stress Disorder, Mild Traumatic Brain Injury, And Combined Posttraumatic Stress Disorder/Mild Traumatic Brain Injury On Returning Veterans, Hannah L. Combs

Theses and Dissertations--Psychology

Veterans of the Iraqi and Afghanistan conflicts have frequently returned with injuries such as mild traumatic brain injury (mTBI) and posttraumatic stress disorder (PTSD). More recently, concern has been raised about the large number of returning soldiers who are diagnosed with both. Literature exists on the neuropsychological factors associated with either alone, however far less research has explored the effects when combined (PTSD+mTBI). With a sample of 206 OEF/OIF veterans, the current study employed neuropsychological and psychological measures to determine whether participants with PTSD+mTBI have poorer cognitive and psychological outcomes than participants with PTSD-o, mTBI-o, or veteran controls (VC), when …

Individual Differences In Escalation Of Tobacco Use: Impulsivity And Alcohol Use, Dustin C. Lee

Theses and Dissertations--Psychology

Like adolescents, young adults are at risk of initiating tobacco use and escalating to daily use and tobacco dependence. However, not every young adult who uses cigarettes intermittently becomes tobacco dependent, and the time-course of those who transition to daily use varies widely. Individual differences likely contribute to the variability observed in patterns of tobacco use. This dissertation uses a multi-modal research approach to examine dimensions of impulsivity and alcohol use that are associated with vulnerability for escalation of cigarette smoking, and whether alcohol’s effects on behavioral disinhibition impact cigarette consumption. Study 1 investigated the associations between dimensions of trait …
