Synthesis And Characterization Of Novel Metal-Ti3sic2 Based Multilayered Composites, Quan Tien Tran

Theses and Dissertations

In this thesis, the design and development of novel multilayered MAX reinforced metal (MRMs) composites is reported. In literature, different studies have focused on MAX Reinforced Metals (MRMs) composites, however no research on MRMs have been on multilayered composites. In this thesis, two different types of composites were designed, (a) Type I, and (b) Type II multilayered composites. In type I composites, MRMs layers were interleaved between metal layers to create a multilayered composite. Similarly, in Type II composites - MRMs were interleaved with two different types of metal layers. In the Chapter II, synthesis of the Ni-Ti3SiC2 multilayered Type …

Northern Great Plains Blizzards In Past And Future Climates, Alexander Trellinger

Theses and Dissertations

Areas that reside in the high-latitudes such as the northern United States can experience hazardous conditions during the winter months due to snowstorms. When strong winds exist with falling or freshly fallen snow, blizzard conditions are able create significant personal, societal, and economic impacts for the Northern Great Plains. While the climatology for these extreme snowstorms is known, the frequency and intensity of how these events may change in a warming climate is not certain. In order to determine how extreme snowstorms may change in the future climate, climate models can be used but the horizontal and vertical grid spacing …

Digital Rock Reconstruction And Property Calculation Of Fractured Shale Rock Samples, Hongsheng Wang

Theses and Dissertations

As the preferential flow channels in the shale reservoir, the fracture systems including the natural micro-cracks and hydraulic fractures have received great attention from the whole energy industry worldwide. However, it is challenging to quantify the fracture systems in the shale rocks precisely because most of well-developed “histogram-based” image processing techniques cannot handle the case of small target segmentation. Because the fracture apertures are very thin, the over-segmentation or insufficient segmentation would lead to significant error in the quantification, including the fracture porosity, aperture, length, tortuosity etc., which would lead to serious mistakes to the property calculation.

In this research, …

Digital Rock Analysis On Berea Sandstone And An Eor Study On Middle Bakken, Barco N. Yolo

Theses and Dissertations

Oil production from tight formations such as the Bakken Formation has experienced a boom in the last decade with recent breakthroughs in horizontal drilling and hydraulic fracturing. However, despite the technological progress, the oil recovery is still less than 10 percent, leaving a considerable amount of potentially recoverable oil. While miscible flooding is well understood in the conventional reservoir, it is not fully explored in unconventional reservoirs. Therefore, it is essential to evaluate different enhanced oil recovery techniques potential in tight shale plays.

In this thesis, the research studies CO2 and ethane interactions with oil at reservoir conditions through laboratory …

Current Approaches And New Developments In The Pharmacological Management Of Tourette Syndrome., Julio Quezada, Keith A. Coffman

Manuscripts, Articles, Book Chapters and Other Papers

Tourette syndrome (TS) is a neurodevelopmental disorder of unknown etiology characterized by spontaneous, involuntary movements and vocalizations called tics. Once thought to be rare, TS affects 0.3-1% of the population. Tics can cause physical discomfort, emotional distress, social difficulties, and can interfere with education and desired activities. The pharmacologic treatment of TS is particularly challenging, as currently the genetics, neurophysiology, and neuropathology of this disorder are still largely unknown. However, clinical experience gained from treating TS has helped us better understand its pathogenesis and, as a result, derive treatment options. The strongest data exist for the antipsychotic agents, both typical …

Human Rights, Christine M. Chinkin

Book Chapters

The legalisation and judicialisation of international human rights have founded arguments that human rights constitutes a sub-discipline of international law, a ‘distinct jurisprudential phenomenon’, indeed a ‘special law’, central to the anxieties about the fragmentation of international law. The human rights world is a very different one from that envisaged by the VCLT: the latter is an empty, amoral world where States have reciprocal dealings only with other States, where there are no people hurt by States’ actions and demanding reparations, no international institutions creating special mechanisms peopled by experts for monitoring and reporting and no non-governmental organizations (NGOs) demanding …

Special Education Enrollment And Classification In Louisiana Charter Schools And Traditional Schools, Shannon Lasserre-Cortez, Patrick Wolf

Curriculum and Instruction Faculty Publications and Presentations

Charter schools are public schools authorized to operate with some independence from district or state public school regulations, while still being held accountable for student outcomes. Like traditional schools operated by school districts, charter schools are free and are intended to be open to all students who desire to attend. This study examined the special education enrollment gap (that is, the gap in the enrollment rate of students with an individualized education program) between charter and traditional public schools in four Louisiana educational regions from 2010/11 to 2013/14 and explored possible sources of the gap. Key findings include: (1) The …

An Exploratory Analysis Of Features Of New Orleans Charter Schools Associated With Student Achievement Growth, Patrick Wolf, Shannon Lasserre-Cortez

Curriculum and Instruction Faculty Publications and Presentations

For decades education policymakers and practitioners have been concerned about improv ing student achievement in New Orleans, Louisiana. After the devastation of Hurricane Katrina in 2005, the public school system in New Orleans, already one of the lowest per forming in the United States, was reorganized, and most schools became charter schools (Harris & Larsen, 2016). As a result, the number of charter schools in New Orleans expanded rapidly. Charter schooling is now the primary governance structure for public education in the city, making New Orleans unique among U.S. school districts. During the 2012/13 school year (the period covered by …

Cultural Assets And Racial Discrimination: A Person-Based Exploration Of Culturally Relevant Coping With African American Male Adolescents, Emma-Lorraine Baaba Bart-Plange

Dissertations

African-American youth from economically-disadvantaged, urban families and communities are disproportionately exposed to stressful life conditions, including racial discrimination, placing them at increased risk for mental health problems (Gonzales & Kim, 1997; Grant et al., 2000). Though exposure to racial discrimination can span a lifetime, examining youths’ encounters with discrimination during adolescence allows us to better understand how they affect development during a critical period in which they are developing racial/ethnic identity and increasing their use of reasoning. Coping research with African American youth has found evidence for racial discrimination predicting use of culturally-relevant coping strategies (Gaylord-Harden & Cunningham, 2009) and …

Entre Dos Tierras: Between Two Lands: Stories Of Latinx Immigrant Students In Us Public High Schools, Yahaira Diaz

Dissertations

The election of the 45th president of the United States has increased a sense of anxiety, fear, and xenophobia for many in our country. The divisive campaign and current discussion of policy is demeaning towards LGBT communities, people with disabilities, women, and ethnic minorities, specifically the immigrant population. The nation’s current preoccupation with and much deserved attention towards a comprehensive immigration reform and the continuance of immigration into the United States has impacted the rise of anti-Hispanic hate crimes and xenophobia (Shihadeh & Barranco, 2013; Stacey, Carbone-Lopez, & Rosenfeld, 2011; Yakushko, 2009). Educators report an increase in hostility against immigrants …

Social Scientists' Conceptualization And Implementation Of Research Ethics And Integrity, Heather A. Pease

Dissertations

The purpose of the current study is to identify core themes, values, and principles through which social scientists conceptualize and implement research ethics and integrity. Periods of rapid growth and interest in research ethics and integrity often coincide with significant scientific discoveries (e.g., mapping of the human genome) or scientific misconduct (e.g., Tuskegee studies). Even though research policies are being developed, they are done in a manner which does not maximize the opportunities to regulate ethics and integrity within social science research. The laws and programs aimed at mitigating acts of misconduct were originally intended for biomedical sciences, yet they …

Voices From The Margins: Service Providers Perspectives On Empowering Refugee Women, Deidra Ann Coleman

Master's Theses

Refugee women face considerable challenges while fleeing their countries, and attempting to adjust to their new lives in their host country. As a result of being both a woman, and a member of a marginalized group, refugee women tend to suffer disproportionately during displacement and and resettlement (UNHCR, 2015). They are more likely to be discriminated due their gender and ethnicity, and to lack the necessary community supports and resources needed to overcome barriers they encounter. In response to the refugee crisis, service organizations have emphasized empowerment as a key way to improve the lives of refugee women. While there …

Mechanotransduction Signaling In Podocytes From Fluid Flow Shear Stress., Tarak Srivastava, Hongying Dai, Daniel P. Heruth, Uri S. Alon, Robert E. Garola, Jianping Zhou, R Scott Duncan, Ashraf El-Meanawy, Ellen T. Mccarthy, Ram Sharma, Mark L. Johnson, Virginia J. Savin, Mukut Sharma

Manuscripts, Articles, Book Chapters and Other Papers

Recently, we and others have found that hyperfiltration-associated increase in biomechanical forces, namely, tensile stress and fluid flow shear stress (FFSS), can directly and distinctly alter podocyte structure and function. The ultrafiltrate flow over the major processes and cell body generates FFSS to podocytes. Our previous work suggests that the cyclooxygenase-2 (COX-2)-PGE2-PGE2 receptor 2 (EP2) axis plays an important role in mechanoperception of FFSS in podocytes. To address mechanotransduction of the perceived stimulus through EP2, cultured podocytes were exposed to FFSS (2 dyn/cm2) for 2 h. Total RNA from cells at the end of FFSS treatment, 2-h post-FFSS, and 24-h …

The Good, The Bad, And The Ugly Of Calcium Supplementation: A Review Of Calcium Intake On Human Health., Kelvin Li, Xia-Fang Wang, Ding-You Li, Yuan-Cheng Chen, Lan-Juan Zhao, Xiao-Gang Liu, Yan-Fang Guo, Jie Shen, Xu Lin, Jeffrey Deng, Rou Zhou, Hong-Wen Deng

Manuscripts, Articles, Book Chapters and Other Papers

Calcium is an important integrative component of the human body and critical for human health. It has been well established that calcium intake is helpful in the prevention and treatment of osteoporosis, which has become one of the most serious public health problems across the world. However, community-dwelling adults with and without osteoporosis are rarely concerned or even not aware of the potential side effects of high or inappropriate doses of calcium intake. Some recent studies have revealed that excessive calcium intake might increase the risks of cardiovascular diseases. The purpose of this article was to review the health benefits, …

Naming Brazil's Previously Poor: “New Middle Class” As An Economic, Political, And Experiential Category, Charles H. Klein, Sean T. Mitchell, Benjamin Junge

Anthropology Faculty Publications and Presentations

The early years of the 21st century were historic for socioeconomic relations in Brazil. While long known for stark socioeconomic inequality, the nation became internationally celebrated for its economic growth and successful poverty-reduction initiatives, which together propelled some 35 million “previously poor” Brazilians into what became called a “new middle class.” The apparent rise of this “new” class has generated contentious debates and a range of social science studies in Brazil; yet this literature is little known in the Anglophone academic world. While some have interpreted this demographic transformation as an expansion of the existing middle class, others have questioned …

The Roles Of Hpa Axis Activity And Attentional Bias In The Development Of Anxiety Symptoms In Low-Income Mexican-Origin Children, Stephanie Brewer

Dissertations

The overarching goal of this research is to increase understanding of the development of anxiety in children of low-income Mexican-origin immigrants. Mexican-origin children display disproportionately high rates of mental disorders such as anxiety, as they face many chronic stressors related to poverty and immigration. A likely mediator of this process is HPA axis activity, causing a buildup of cortisol in the body in response to chronic stress. There is a large amount of evidence indicating that HPA axis activity is a mechanism through which accumulated poverty-related stress causes mental illness, but this mediator has not been examined in relation to …

Trauma-Focused Cognitive Behavioral Therapy With A Teacher Component: Outcomes Examined In A School Setting, Kelly Marie Holmes

Dissertations

Trauma exposure among youth is common and can result in long-term social-emotional, behavioral, and academic problems (Finkelhor, Turner, Hamby, & Ormrod, 2011; Kronenberg et al., 2010). Fortunately, there are interventions that can ameliorate these problems. In particular, trauma-focused, interventions are effective in reducing trauma related symptomatology and problems among youth (Cary & McMillen, 2012). Trauma exposure among youth is common and can result in long-term social-emotional, behavioral, and academic problems (Finkelhor, Turner, Hamby, & Ormrod, 2011). Additionally, most youth receive mental health services in schools (Green et al., 2013). Fortunately, there are school-based, trauma-focused interventions that have been found to …

Intercultural Proficiency Of Principals Leading Ib Schools In Urban America, Ahlam Bazzi Moughania

Dissertations

This study, based on the qualitatively rendered experiences and perceptions of racially or ethnically diverse school principals leading International Baccalaureate (IB) public schools in the urban America, argues that intercultural proficiency development and intersectionality of race/ethnicity and gender identity influence school leadership practice. To make this point, I draw on the intercultural competence theoretical framework, intersectionality, and culturally responsive school leadership. Through a qualitative methodology, a comparative three-case study is identified from a larger sample of IB schools reported to be favorably employing the Learner Profile, a learner framework fostering the development intercultural understanding. Interview with school principal and visuals …

Work Only We Can Do: Professional Responsibility In An Age Of Automation, Sherman J. Clark

Articles

Automation can help us do our work as lawyers; but in the process, it should also force us to be more thoughtful about what our work really is or ought to be.' The challenge for the profession, as I see it, is not simply to survive the advent of new technology, nor even merely to make effective use of new tools. While addressing those immediate concerns, we should also welcome the concomitant opportunity to develop and refine our understanding of what it means to be a good and ethical lawyer. As technological developments free us from and prevent us from …

Fraudulent Conveyances Masquerading As Asset Protection Trusts, James J. White

Articles

Viewed with a dispassionate but slightly skeptical eye, transfers to asset protection trusts are fraudulent conveyances pure and simple. I think so and the evidence points that way.

The asset protection trust is a simulacrum of the well-known and thoroughly conventional mode of holding assets for a “beneficiary” by a “trustee” under the terms of an elaborate document. Trusts, of course, are widely used in estate planning and elsewhere in circumstances where one person, the settlor, wishes to make assets available to another on the settlor’s terms; a parent might use a trust to put aside assets for a minor …
