Dual-Modality Thermoacoustic And Photoacoustic Imaging, Manojit Pramanik Jan 2010

Dual-Modality Thermoacoustic And Photoacoustic Imaging, Manojit Pramanik

All Theses and Dissertations (ETDs)

Diagnosis of early breast cancer is the key to survival. The combined contrasts from thermoacoustic and photoacoustic tomography: TAT and PAT) can potentially predict early stage breast cancer. We have designed and engineered a breast imaging system integrating both thermoacoustic and photoacoustic imaging techniques to achieve dual-contrast: microwave and light absorption), non-ionizing, low-cost, high-resolution, three-dimensional breast imaging. We have also developed a novel concept of using a negative acoustic lens to increase the acceptance angle of an unfocused large-area ultrasonic transducer: detector), leading to more than twofold improvement of the tangential resolution in both TAT and PAT when the object …

A consideration of three State Songs, ΓÇ£My Old Kentucky HomeΓÇ¥ by Stephen Foster, ΓÇ£Carry Me Back to Old VirginnyΓÇ¥ by James A. Bland, and ΓÇ£The Missouri WaltzΓÇ¥ with lyrics by James Royce Shannon. The combination of black dialect and negative stereotypes, with elevation to special status impacting identity, necessitated their alteration. Such change reflects societal response to the Civil Rights Movement, while a pragmatic view suggests these malleable artifacts have functioned, and continue to function, as ΓÇ£blue notes,ΓÇ¥ unsettling elements acting to stimulate discourse, becoming participants in the formation of identity and American cultural change.

Pattern Formation And Magnetism In Pulsed Laser-Induced Self-Organized Nanostructures From Single And Bilayer Metallic Films, Hare Krishna Jan 2010

Pattern Formation And Magnetism In Pulsed Laser-Induced Self-Organized Nanostructures From Single And Bilayer Metallic Films, Hare Krishna

All Theses and Dissertations (ETDs)

Self-organization via nanosecond pulsed laser melting of thin metal films is attractive as a reliable and low cost method to create surface metallic nanostructures. The potential applications of these resulting structures are related to their magnetic, optical, plasmonic, and magneto-optical properties, such as in high density magnetic storage, energy harvesting, and sensing. In this dissertation experimental and theoretical mechanisms of nanoscale patterning by dewetting self-organization was explored in nanoscopic thickness single and bilayer metal films. Magnetism in the resulting nanostructures was also explored. Experimental techniques included thin film deposition, laser irradiation, scanning and transmission electron microscopy, atomic force and magnetic …

Nucleation Control In Size And Dispersity In Metallic Nanoparticles: The Prominent Role Of Particle Aggregation, Vernal Richards Jan 2010

Nucleation Control In Size And Dispersity In Metallic Nanoparticles: The Prominent Role Of Particle Aggregation, Vernal Richards

All Theses and Dissertations (ETDs)

The aim of this project is to investigate the effect of aggregative nucleation and growth on the final size and dispersity in metallic nanoparticle systems. Aggregative nucleation functions are determined for the first time for three nanocrystal systems, namely gold: Au), silver: Ag) and bismuth: Bi). These nucleation functions give critical information that correlates closely with the size and dispersity of t+X123he nanocrystals synthesized. The aggregative nucleation functions and growth kinetics of pre-synthesized Au nanoparticles as a function of tetra-n-octylammonium bromide: n-octyl4NBr) is investigated. For each kinetic trial, the time dependence of the aggregative nucleation rate is extracted from the …

Ornithine Decarboxylase (Odc) Regulation By Mtor: New Insights From Tsc1 Knockout Cells, Alyssa Mae Cates Jan 2010

Ornithine Decarboxylase (Odc) Regulation By Mtor: New Insights From Tsc1 Knockout Cells, Alyssa Mae Cates

Honors Program Theses

The polyamine pathway, when improperly regulated, is one central cause of skin carcinogenesis. The purpose of this project was to investigate the relationship between two biochemical signaling pathways, the mTOR (mammalian target of rapamycin) pathway and the polyamine pathway. It is known that the protein mTOR serves to regulate a key protein in the polyamine pathway, ornithine decarboxylase (ODC), but the precise mechanism remains unclear. It has been postulated that mTOR acts to regulate ODC through two RNA binding proteins, HuR (a member of the Hu family of proteins) and TIP (tristetraprolin). The project entailed characterizing that relationship using TSCl …

Campaigning In Judicial Elections: The Effects Of Candidate Status, Katelyn Marie Bries Jan 2010

Campaigning In Judicial Elections: The Effects Of Candidate Status, Katelyn Marie Bries

Honors Program Theses

While campaigns for judicial elections in general have received more attention, relatively little research has been done regarding the differences in campaigning for open-seat and incumbent-challenger elections. Because they are the most common type of judicial election, incumbent-challenger races have been the focus of most research conducted thus far. Yet, open seat competitions are important as well. With the incumbent advantage absent in these elections, factors that would otherwise play only a minor role in determining who will be elected have the potential to be much more exaggerated than they do in incumbent-challenger races; consequently, it will be easier to …

Towards Cloning A Tyrosinase Gene From Pitayas, Kurt J. Chamberlain Jan 2010

Towards Cloning A Tyrosinase Gene From Pitayas, Kurt J. Chamberlain

Honors Program Theses

Betalains, such as those produced by pitayas, are water-soluble nitrogen-containing pigment molecules (Gandia-Herrero et al., 2005). In most families of the Caryophyllales, betalains replace anthocyanins, which are the pigment molecules found in all other families of flowering plants (Strack et al., 2001). Betalains accumulate in the flowers, fruits, and occasionally vegetative tissues of these plants (Strack et al., 2001). Depending on the structure of the molecule, betalains are classified as either betacyanins or betaxanthins. Betacyanins contribute to red-violet coloration, while betaxanthins contribute to the yellow-orange coloration found only in a limited number of plant species (Gandia-Herrero et al., 2005). The …

Seeking Alternatives To Marijuana Prohibition, Rachel Kiesel Jan 2010

Seeking Alternatives To Marijuana Prohibition, Rachel Kiesel

Honors Program Theses

Marijuana legality is a highly controversial social issue. Although our society continues to be bombarded by negative images of drugs and crime in the media, cultural perceptions regarding marijuana have been changing over the past few years. Today, many people are more accepting of marijuana use than ever before. As a result of these shifting attitudes, several states have taken the initiative to pass new legislation on regulating marijuana with reduced restrictions.

A Model Copyright Exemption To Serve The Visually Impaired, Patrick Hely Jan 2010

A Model Copyright Exemption To Serve The Visually Impaired, Patrick Hely

Vanderbilt Journal of Transnational Law

Copyright law presents visually impaired persons with serious barriers to access of the written word. A recent international effort seeks to remove these barriers to access, in limited instances, by allowing the creation of accessible formats of copyrighted works. While bodies like the World Blind Union--through several South American states--have presented draft treaties to the World Intellectual Property Organization (WIPO), to date the interested parties have not found a mutually agreeable solution. This Note surveys international intellectual property law as it relates to the problem, draws a comparison to the humanitarian concerns entangled with international patent law, and tracks the …

Quality Of Life Among Rural Nigerian Women: The Role Of Information, Yetunde Abosede Zaid, S. O. Popoola

Library Philosophy and Practice (e-journal)

The quality of life of people in developing countries including Nigeria is not near the expected standard. This is especially so with women living in the rural areas whose lives are characterized by poor income, poverty, hunger, diseases as well as lack of potable water, good shelter and access to medical attention. This is due to the fact that these women do not have access to valuable information and may not make use of available information which could help them meet the challenges of daily living. This study, therefore, investigated the extent to which information accessibility and use could improve …

Diversity's Strange Career: Recovering The Racial Pluralism Of Lewis F. Powell, Jr., Anders Walker Jan 2010

Diversity's Strange Career: Recovering The Racial Pluralism Of Lewis F. Powell, Jr., Anders Walker

All Faculty Scholarship

Though diversity remains a compelling state interest, recent rulings like Ricci v. DeStefano and Parents’ Involved toll a menacing bell for schools employing racial classifications to admit minority students. Yet, defenders of diversity may find refuge in original meanings, particularly the original meaning of diversity as articulated by Justice Lewis F. Powell, Jr. in Regents v. Bakke in 1978. Virginian by birth, Powell’s interest in “genuine diversity” coincided with a forgotten version of pluralism extant in the American South during thefirst half of the Twentieth Century. Further, Powell’s conviction that diversity distinguished America coalesced during a trip to the Soviet …

The Wisdom Of Legislating For Anticipated Technological Advancements, Yvette Joy Liebesman

All Faculty Scholarship

The past four decades have been witness to the realization of ideas which, when first contemplated, seemed to resemble the prose of science fiction writers. Some seemingly far-fetched notions, such as robot pets, anti-sleeping pills, and ugly unisex jumpsuits, are now readily available. However, there are currently no colonies on the moon, and we are all still waiting to order our personal jetpacks from Amazon.com. Some are likely to remain in the realm of science fiction and will only be realized with the help of movie and television special effects artists. Yet through these entertaining glimpses into a potential future, …

Behavioral Decision Theory And Implications For The Supreme Court’S Campaign Finance Jurisprudence, Molly J. Walker Wilson Jan 2010

Behavioral Decision Theory And Implications For The Supreme Court’S Campaign Finance Jurisprudence, Molly J. Walker Wilson

All Faculty Scholarship

America stands at a moment in history when advances in the understanding of human decision-making are increasing the strategic efficacy of political strategy. As campaign spending for the presidential race reaches hundreds of millions of dollars, the potential for harnessing the power of psychological tactics becomes considerable. Meanwhile, the Supreme Court has characterized campaign money as “speech” and has required evidence of corruption or the appearance of corruption in order to uphold restrictions on campaign expenditures. Ultimately, the Court has rejected virtually all restrictions on campaign spending on the ground that expenditures, unlike contributions, do not contribute to corruption or …

Too Much Of A Good Thing: Campaign Speech After Citizens United, Molly J. Walker Wilson Jan 2010

Too Much Of A Good Thing: Campaign Speech After Citizens United, Molly J. Walker Wilson

All Faculty Scholarship

In January 2010, the Supreme Court in Citizens United v. Federal Election Commission overturned Austin v. Michigan Chamber of Commerce and the portion of McConnell v. Federal Election Commission that restricted independent corporate expenditures, as codified in section 203 of the Bipartisan Campaign Reform Act. Specifically, Citizens United invalidated laws forbidding corporations and unions from using general treasury funds for “electioneering communication,” political advocacy transmitted by broadcast, cable, or satellite communication in the period leading up to a federal election. The effect of Citizens United was to protect the right of corporations, no less than individual American citizens, to fund …

Race, Sex And Genes At Work: Uncovering The Lessons Of Norman-Bloodsaw, Elizabeth Pendo

All Faculty Scholarship

The Genetic Information Nondiscrimination Act of 2008 (“GINA”) is the first federal, uniform protection against the use of genetic information in both the workplace and health insurance. Signed into law on May 21, 2008, GINA prohibits an employer or health insurer from acquiring or using an individual’s genetic information, with some exceptions. One of the goals of GINA is to eradicate actual, or perceived, discrimination based on genetic information in the workplace and in health insurance. Although the threat of genetic discrimination is often discussed in universal terms - as something that could happen to any of us - the …

Back To Color Blindness: Recent Developments In Race Discrimination Law In The United States, Marcia L. Mccormick Jan 2010

Back To Color Blindness: Recent Developments In Race Discrimination Law In The United States, Marcia L. Mccormick

All Faculty Scholarship

The United States has a long and somewhat conflicted history of espousing egalitarian values and yet tolerating a certain level of subordination of particular groups to a greater or lesser extent at the same time. Like many countries, it struggles with reconciling the goals of equality, pluralism, and liberty, and the balance has been struck differently at different times. In the current wave of such efforts, the Supreme Court is marking an increasingly formalist approach to the question of discrimination, while Congress appears to be pushing a slightly more substantive approach to discrimination. This short paper analyzes the Court’s recent …

Regulatory Adjudication, Marcia L. Mccormick

All Faculty Scholarship

Calls for increased regulation are flying fast and furious these days. We use regulation in the United States to prevent harm that various kinds of activities might cause and also to create positive external benefits that those activities could yield, but might not without incentives. Most regulatory programs in the United States provide a blend of measures designed to create these positive external benefits, promote good practices in the industry, prevent harms, and provide those harmed with remedies. At a time in which we contemplate new ways to regulate to deal with the crises of the day and prevent the …

Human Capital And Transfer Taxation, Kerry A. Ryan Jan 2010

Human Capital And Transfer Taxation, Kerry A. Ryan

All Faculty Scholarship

This article addresses the question of whether education and healthcare transfers should be included in the federal gift tax base. It initially frames the issue in two ways: (1) through the lens of a proposal by the American Law Institute to exempt all “transfers for consumption” from gift taxation, and (2) within the context of a debate among economists about whether such expenditures should be included in the definition of “intergenerational transfers” for purposes of determining the total share of such transfers in U.S. accumulated wealth. Finding the first lens unsatisfactory on its own doctrinal terms and the second lens …
