Deformation Induced Martensitic Transformation In 304 Stainless Steels, Junliang Liu

Theses and Dissertations

304 stainless steel is an austenitic steel widely used for various applications due to a good combination of strength and ductility and relative low cost. It is known to be metastable as the austenite phase can transform into martensite under stress. In this work, a new method (in-situ tensile TEM) and the traditional method (ex-situ tensile tests and TEM, XRD characterization) were used to investigate the mechanisms of deformation-induced martensitic transformation in 304SS samples at different temperatures.

The ex-situ tensile tests were conducted under a strain rate of 10-3 s-1 until rupture. After the tensile tests, the fractured area was …

The Influence Of Romantic Poetry On The Career And Music Of Nicolas Medtner, Denise Rudell

Theses and Dissertations

Nicolas Medtner was a composer born out of his time. He was a true Romantic in the Russian Silver Age and his creative ideology owes much to the Romantic poetry that he was devoted to all his life. This poetry put a decisive stamp on his music and influenced his career decisions. Medtner was exposed to the most renowned literature from an early age. Influenced by his father, and his oldest brother Emil, he developed a lifelong love for literature and especially poetry. Literary connections are apparent throughout Medtner’s music, including (and not limited to) references to Goethe, Pushkin, Lermontov, …

Influence Of Built Environment On Physical Activity Outcomes Among African Americans In Community-Based Obesity Intervention Studies, Amanda Sue Thomas

Theses and Dissertations

More than sixty-five percent of people in the U.S. are considered overweight or obese. African-Americans in the U.S. have a higher risk of obesity than any other racial group. One way to reduce this statistic is physical activity. Recreational green spaces (parks) can serve as an avenue to complete the 150 min/wk of recommended physical activity for adults by the ACSM. Data from SISTAS and HEALS interventions, that recruited overweight/obese African-Americans from Columbia and Florence, SC, was used to assess the association of recreational green space (parks) around a residence and physical activity. Physical activity measures of RAPA questionnaire (self-report), …

Iv Prenatal Nicotine Exposure Modulates Α6, Α7, And Α4Β2 Nicotinic Acetylcholinergic Receptor Subunit Expression In Male And Female Neonatal And Adolescent Rat Offspring: An Autoradiographical Analysis, Amanda Morgan

Theses and Dissertations

Maternal smoke exposure produces long-term adverse cognitive and behavioral outcomes in offspring, including an increased likelihood of attention problems (e.g., attention deficit hyperactivity disorder; ADHD) and drug abuse. Preclinical research shows that gestational exposure to nicotine, the primary psychoactive compound in tobacco smoke, influences the neurodevelopment of attention and reward neuronal circuits. This study investigated hypotheses about five brain regions, to determine if prenatal nicotine (PN) exposure altered expression of nicotinic acetylcholine receptors (nAChRs). A low dose, intravenous nicotine (IV) exposure method was used to administer nicotine (0.05 mg/kg/injection) or saline, 3x/day on gestational days 8–21 (Treatment). Brain tissue was …

Utilization Of Satellite-Derived Salinity For Enso Studies And Climate Indices, Caroline Mary Corbett

Theses and Dissertations

Conventionally, El Niño-Southern Oscillation (ENSO) is studied using sea surface temperature (SST) observations in the central and eastern equatorial Pacific Ocean. Recently, sea surface salinity (SSS) in the equatorial Pacific has been studied in relation to the phases of ENSO. Previously, SSS was observed in the equatorial Pacific using the Tropical Ocean Global Atmosphere (TOGA) / Tropical Atmosphere Ocean (TOA), the Argo float network, and Oceanic General Circulation Models (OGCM). The launch of NASA’s Aquarius Salinity Mission and ESA’s Soil Moisture Ocean Salinity (SMOS) opened a new era in which high resolution global near real-time SSS observations are readily available. …

The Early Pottery Of San Antonio, Department Of Chinandega, Nicaragua, Kelsey I. Willis

Electronic Theses and Dissertations

I analyzed the potsherds (n=732) recovered from the 2009 archaeological excavations at the site of San Antonio in Chinandega, Nicaragua. I classified the pottery in accordance with the Type: Variety-Mode system that is used almost exclusively in Mesoamerica and the Greater Nicoya Sub-Region. Identifications of known ceramic wares, groups, types, and varieties were made through comparisons with reference specimens from type collections housed at several institutions. New taxa were defined as needed in accordance with the established protocols of the Type: Variety system (e.g., Smith et al. 1960) and as subsequently amended (e.g., Rice 1976). In the thesis, I describe …

The Informational And Emotional Support Needs Of Grandparents Of Children With Pompe Disease, Natasha Lousie Rudy

Theses and Dissertations

The complex roles and experiences of grandparents of children with various diagnoses have been described, but previous studies have not investigated the roles and experiences of grandparents of children with treatable, Mendelian conditions such as Pompe disease. The availability of treatment and heritable nature of Pompe introduce the possibility for unique grandparent roles, experiences and needs. This is a particularly timely investigation given the advent of newborn screening for Pompe. This study aimed to characterize grandparents’ roles and involvement, identify grandparents’ information and emotional support needs, and explore the psychosocial impact felt by grandparents of children with Pompe. An online …

A Mechanical Approach To The Characterization Of Material Failure Of Atherosclerotic Lesions, Lindsey A. Davis

Theses and Dissertations

Failure of atherosclerotic plaques can lead to potentially life threatening clinical events such as myocardial infarction (MI), stroke, or transient ischemic attack (TIA). The most frequently described plaque failure mechanism is tensile rupture of the fibrous cap; however, often during angioplasty another plaque failure mechanism occurs in which the atherosclerotic plaque separates from the internal elastic lamina (IEL). This study aims assess the material strength of atherosclerotic lesions using mechanical concepts.

To assess likelihood of plaque dissection at the vessel wall, adhesion strength was assessed in both mouse and human specimens using plaque delamination experiments. Measuring plaque adhesion in transgenic …

Frailty Probit Models For Clustered Interval-Censored Failure Time Data, Haifeng Wu

Theses and Dissertations

Survival analysis is an important branch of statistics that deals with time to event data or survival data. An important feature of such data is that the survival time of interest is usually not completely known but is censored due to the design of the study or an early dropout. In this dissertation we focus on studying clustered interval-censored data, a special type of survival data. Interval-censored data arise in many epidemiological, social science, and medical studies, in which subjects are examined at periodical follow-up visits. The survival (or failure) time of interest is never exactly observed but is known …

Mechanical Characterization Of Sicf-Sicm Nuclear Fuel Cladding By A Novel Hydraulic Internal Pressurization Method, Kirill Shapovalov

Theses and Dissertations

Ceramic Matrix Composites (CMC) have been actively researched for applications requiring high temperature strength and damage tolerance. Examples are turbine engine hot section components, leading edges for hypersonic vehicles, nuclear fusion reactor first wall and blanket, and recently nuclear fuel claddings. Predictable material damage behavior is desirable for these applications so early damage accumulation can be detected before a catastrophic failure occurs. Many ceramic materials can withstand high temperature environments, but due to inherent brittleness of ceramics the high damage tolerance and the predictable damage behavior are difficult to achieve. Ceramic fiber reinforced ceramic composites (CFCC) have demonstrated the above …

A Theoretical Study Of Polymer Based Drug Delivery Systems, Ebtisam Abdullatif Aldaais

Theses and Dissertations

Polymer nanostructured materials for drug delivery applications have witnessed tremendous progress in recent years due to their vast potential. One-end-grafted polymers can form grafted micelles with specific mechanical properties. Biological conditions can alter these properties resulting in the protection or release of drugs. Charged surfactants can also form micelles in an aqueous solution, which can also be manipulated through special conditions. On the micellar surface, self-organized polyelectrolytes can be stimulated to extend their attached ligands and thus increase the probability of binding to targeted receptors. This thesis focuses on modeling polymer-based drug delivery systems by studying the physical interactions between …

Trust In China? The Impact Of Development, Inequality, And Openness On Political Trust Across China’S Provinces, 2001-2012, Marc L. Hutchison, Ping Xu

Political Science Faculty Publications

China has long represented a puzzle for scholars of democracy, who view political trust as an important indicator of regime legitimacy. Previous studies show that while democracies around the world experienced declining levels of political trust, the authoritarian Chinese government maintained unexpectedly high levels of trust. Using World Value Survey (WVS) data over a critical twelve-year period (2001-2012) and multilevel modeling techniques, we explore both macro- and individual-level determinants of political trust in China. We find that province-level economic performance and individual level income combine to influence political trust. Higher levels of individual-level income have a positive effect on trust …
