Design Of Organic Tandem Solar Cells Using Pcpdtbt: Pc61 Bm And P3ht: Pc71bm, Gon Namkoong, Patrick Boland, Keejoo Lee, James Dean

Electrical & Computer Engineering Faculty Publications

We conducted optical and electrical simulations with the goal of determining the optimal design for conjugated polymer-fullerene tandem solar cells using poly[2,6-(4,4-bis-(2-ethylhexyl)- 4H-cyclopenta[2,1- b;3,4- b′] dithiophene)-alt-4,7-(2,1,3-benzothiadiazole)] (PCPDTBT): [6,6]-phenyl C₆₁ butyric acid methyl ester (PC₆₁ BM) as a bottom cell and poly(3-hexylthiophene) (P3HT): [6,6]-phenyl C₇₁ butyric acid methyl ester (PC₇₁BM) as a top cell. The effects of photon density, absorption, balanced and unbalanced charge carrier transport, and bimolecular recombination in the two subcells were incorporated into the simulations. We found that the maximum energy conversion efficiency (η) is 9% when charge carrier mobilities in …

Dissecting The Biosyntheses Of Gilvocarcins And Ravidomycins, Madan Kumar Kharel

University of Kentucky Doctoral Dissertations

Gilvocarcin V (GV) and ravidomycin (RMV) exhibit excellent antitumor activities in the presence of near-UV light at low concentration maintaining a low in vivo cytotoxicity. Although, the exact molecular mechanism for in vivo actions of these antibiotics has yet to be determined, a [2+2] cycloaddition reaction of the vinyl side chain with DNA thymidine residues in addition to the inhibition of topoisomerase II and DNAhistone H3 cross-linking are reported for the GV’s mechanism of action. Such activities have made these molecules interesting candidates for the biosynthetic investigation to generate analogues with improved activity/solubility. Previous biosynthetic studies have suggested that the …

Synthesis And Characterization Of Magnetic Hydrogel Nanocomposites For Cancer Therapy Applications, Samantha Ann Meenach

University of Kentucky Doctoral Dissertations

Currently, cancer is the second leading cause of death in the United States. Conventional cancer treatment includes chemotherapy, radiation, and surgical resection, but unfortunately, all of these methods have significant drawbacks. Hyperthermia, the heating of cancerous tissues to between 41 and 45°C, has been shown to improve the efficacy of cancer therapy when used in conjunction with irradiation and/or chemotherapy. In this work, a novel method for remotely administering heat is presented. This method involves heating of tumor tissue using hydrogel nanocomposites containing magnetic nanoparticles which can be remotely heated upon exposure to an external alternating magnetic field (AMF). The …

Novel Approaches In Structured Light Illumination, Yongchang Wang

University of Kentucky Doctoral Dissertations

Among the various approaches to 3-D imaging, structured light illumination (SLI) is widely spread. SLI employs a pair of digital projector and digital camera such that the correspondences can be found based upon the projecting and capturing of a group of designed light patterns. As an active sensing method, SLI is known for its robustness and high accuracy. In this dissertation, I study the phase shifting method (PSM), which is one of the most employed strategy in SLI. And, three novel approaches in PSM have been proposed in this dissertation. First, by regarding the design of patterns as placing points …

Dissertations and Theses @ UNI

This study will review literature related to leisure and aging. We live in an aging society. People are expected to live healthier and longer. Therefore, there is a need to analyze how older adults are portrayed in leisure textbooks and academic journal articles which are typically used to educate and train recreation professionals. This study explores whether leisure textbooks published in the United States addressed the topic of aging and, if so, to what extent. In addition, any differences between leisure textbooks and specialty leisure and aging textbooks were analyzed. A content analysis of 54 leisure textbooks from six U.S. …

Conflicting Identities And Ideologies: A Rhetorical Analysis Of The National Japanese American Memorial To Patriotism During World War Ii, Kaori Yamada

Dissertations and Theses @ UNI

This thesis is a rhetorical criticism of the National Japanese American Memorial to Patriotism During World War II, located in Washington, D.C. It was erected on November 9, 2000, to memorialize Japanese Americans who were forced to move to the relocation camps and Japanese American soldiers who died as members of the U.S. armed forces during WWII. Examining the intended meaning of the Memorial by its creators is not a central focus of this study. Rather, I investigate how interactions among the rhetoric of the Memorial, social contexts, and audiences create multiple meanings.

The first analytic focus is the symbolic …

Periodontal Bacterial-Dna Initiated Immuno-Inflammatory Responses In Human Osteoblastic Cells, Chebel Najib Bou

Theses and Dissertations

Periodontitis is a chronic inflammatory disease initiated by gram negative anaerobic bacteria. These bacteria possess pathogen-associated molecular patterns (PAMPs) that interact with various receptors including Toll like receptors (TLRs). Bacterial DNA (bDNA) is one of the PAMPs mainly recognized by TLR9. Interaction of bDNA and its receptors leads to activation of inflammatory signaling pathways potentially resulting in periodontal bone destruction. The aim of this study was to determine the production of IL- 6 and IL-8 in response to periodontal bDNA from human osteoblastic cells (MG-63). MG- 63 cells were stimulated in duplicate for 20 hours with 100ng/μl of bDNA from …

Human Rights And American Bioethics: Resistance Is Futile, George J. Annas

Faculty Scholarship

The Borg are always confident that humans will be assimilated into their collective hive and therefore that, as they say, “resistance is futile.” In Star Trek, of course, the humans always successfully resist. Elizabeth Fenton and John Arras, like the Borg, resist the idea that humans are uniquely special as well as the utility of the human rights framework for global bioethics. I believe their resistance to human rights is futile, and I explain why in this essay. Let me begin with their subtitle, because we do seem to agree that popular culture is a powerful aid to understanding human …

Assistive Technology Attrition: Identifying Why Teachers Abandon Assistive Technologies, Michael Edward Sharpe

CCAC Theses and Dissertations

The study surveyed a sample of K-12 teachers who had used assistive technology (AT) in the classroom to determine answers to five research questions. These were, (1) why the teachers adopted AT, (2) their attitudes and perceptions about its value, (3) challenges they have experienced in adopting AT, (4) whether they have discontinued or decreased use of AT, and, if so, (5) the factors that led to this result.

The study used both quantitative and qualitative methods. For the quantitative aspect, an online survey instrument was developed to answer five research questions. Participants were teachers who had used AT in …

Trust And Trustworthiness: A Framework For Successful Design Of Telemedicine, James Robert Templeton

CCAC Theses and Dissertations

Trust and its antecedents have been demonstrated as a barrier to the successful adoption of numerous fields of technology, most notably e-commerce, and may be a key factor in the lack of adoption or adaptation in the field of telemedicine. In the medical arena, trust is often formed through the relationships cultivated over time via clinician and patient. Trust and interpersonal relationships may also play a significant role in the adoption of telemedicine. The idea of telemedicine has been explored for nearly 30 years in one form or another. Yet, despite grandiose promises of how it will someday significantly improve …

by

Keith P. Lyons

June 2010

Public libraries require efficient control systems to maintain accurate inventories, statistics, and records of patron borrowing. Generally, public libraries use barcode technology to accomplish these tasks. Radio frequency identification (RFID) has gained the attention of public library personnel in recent years as a replacement for barcodes. RFID implementation contributes to improved staff productivity, increased operational efficiency, and improved item security as well. While potential benefits are significant, issues …

Physician Information Seeking Behaviors: Are Physicians Successful Searchers?, Janice Swiatek-Kelley

CCAC Theses and Dissertations

In the recent past, physicians found answers to questions by consulting colleagues, textbooks, and professional journals. Now, the availability of medical information through electronic resources has changed physician information-seeking behaviors. Evidence-based medicine is now the accepted decision-making paradigm, and a physician's ability to locate best practice guidelines through electronic information resources has become an essential skill. As physicians struggle to stay current in the wake of an ever-growing volume of medical information, several electronic resources claim to provide one-stop access to the most current information with correct and complete answers to problems encountered in the practice of health care. The …

International Agreements, Internal Heterogeneity, And Climate Change: The "Two Chinas" Problem, Daniel Abebe, Jonathan S. Masur

Faculty Scholarship

Every quantitative forecast of Chinese emissions – save for two important exceptions – uses only national-level data, a methodological weakness that can wash out distinctions between East and West. Of the two studies that employ sub-national data, one projects higher emissions than any of the national-level studies; the other projects much higher emissions than any other study. We read this as suggesting that Chinese carbon emissions over the forthcoming several decades may be significantly greater than the standard models have anticipated, with correspondingly higher costs to China from any agreement to curb carbon emissions. In light of the importance of …

Climate Regulation Without Congressional Action, Michael B. Gerrard

Faculty Scholarship

The apogee of congressional support for comprehensive climate change legislation came on June 26, 2009, when the House of Representatives passed the American Clean Energy Security Act (Waxman-Markey) by a vote of 219 to 212. Its Senate counterpart, the American Power Act, known first as Kerry-Lieberman-Graham and then just Kerry-Lieberman, never gained traction, and in July 2010 Senate Majority Leader Harry Reid (D.-Nev.) announced he would not bring it to the floor this year.

Many observers believe Republicans will take control of the House and possibly of the Senate after the Nov. 2, 2010, elections. Republican leadership in both chambers …

Model Green Building Ordinance For Municipalities Open For Comment, Michael B. Gerrard

Faculty Scholarship

In 2009, the residential and commercial building sector was responsible for more than 50 percent of total annual U.S. energy consumption, 74 percent of total U.S. electricity consumption, and 39 percent of total U.S. greenhouse gas emissions.

There has been a growing movement to encourage “green buildings” – those that generally use water, energy and materials more efficiently than conventional buildings, and utilize design, construction and siting features to reduce their negative environmental impacts.

Model Green Building Ordinance Proposed For Adoption By New York Municipalities, Michael B. Gerrard, Jason James

Faculty Scholarship

After failing to pass in the 111th Congress, comprehensive federal climate legislation appears stalled until at least 2013. Regulation of greenhouse gas emissions under existing federal law, while progressing, has encountered challenges. Even state initiatives, such as California's A.B. 32, lie on less than certain ground. But not all action to reduce greenhouse gas emissions must be taken on the federal or state level. Through regulating buildings, municipalities can play a crucial role in reducing greenhouse gas emissions while improving the health and welfare of their local communities.

In 2009, the residential and commercial building sector was responsible for more …

Mental Reversal Of Imagined Melodies: A Role For The Posterior Parietal Cortex, Robert J. Zatorre, Andrea R. Halpern, Marc Bouffard

Faculty Journal Articles

Two fMRI experiments explored the neural substrates of a musical imagery task that required manipulation of the imagined sounds: temporal reversal of a melody. Musicians were presented with the first few notes of a familiar tune (Experiment 1) or its title (Experiment 2), followed by a string of notes that was either an exact or an inexact reversal. The task was to judge whether the second string was correct or not by mentally reversing all its notes, thus requiring both maintenance and manipulation of the represented string. Both experiments showed considerable activation of the superior parietal lobe (intraparietal sulcus) during …

Thermal Analog To Afm Force-Displacement Measurements For Nanoscale Interfacial Contact Resistance, Brian D. Iverson, John E. Blendell, Suresh V. Garimella

Faculty Publications

Thermal diffusion measurements on PMMA-coated Si substrates using heated AFM tips were performed to determine the contact resistance between an organic thin film and Si. The measurement methodology presented demonstrates how the thermal contrast signal obtained during a force-displacement ramp is used to quantify the resistance to heat transfer through an internal interface. The results also delineate the interrogation thickness beyond which thermal diffusion in the organic thin film is not affected appreciably by the underlying substrate.

Miami Ocean-Dredged Material Disposal Site: Tilefish(Malacanthidae) Habitat Identification And Characterization Study., John K. Reed, J. Seitz

Faculty Scholarship

The USACE Jacksonville District has identified a need to have the 1986 video dataset reviewed and analyzed for the possible presence of species of fisheries management interest. Preliminary review of the video records indicated possible tilefish (Malacanthidae) habitat evidenced by the presence of large burrows in soft substrate. The main objective of this project is to confirm or deny the presence of tilefish or tilefish burrows in the Miami ODMDS based on the 1986 video transects. In the event that the presence of tilefish is confirmed (based on video evidence), analyses will include an estimation of distribution and abundance within …

Fault Testing Quantum Switching Circuits, Marek Perkowski, Jacob Biamonte

Electrical and Computer Engineering Faculty Publications and Presentations

Test pattern generation is an electronic design automation tool that attempts to find an input (or test) sequence that, when applied to a digital circuit, enables one to distinguish between the correct circuit behavior and the faulty behavior caused by particular faults. The effectiveness of this classical method is measured by the fault coverage achieved for the fault model and the number of generated vectors, which should be directly proportional to test application time. This work address the quantum process validation problem by considering the quantum mechanical adaptation of test pattern generation methods used to test classical circuits. We found …

Braiding: The Interaction Of Formal And Informal Contracting In Theory, Practice, And Doctrine, Ronald J. Gilson, Charles F. Sabel, Robert E. Scott

Faculty Scholarship

This Article studies the relationship between formal and informal contract enforcement. The theoretical literature treats the two strategies as separate phenomena. By contrast, a rich experimental literature considers whether the introduction of formal contracting and state enforcement "crowds out" the operation of informal contracting. Both literatures focus too narrowly on how formal contracts create incentives for parties to perfom substantive actions, while assuming that informal enforcement depends on preexisting levels of trust. As a result, current scholarship misses the relationship between formal and informal contract mechanisms that characterizes contemporary contracting in practice. Parties respond to rising uncertainty by writing contracts …

Judicial Elections As Popular Constitutionalism, David E. Pozen

Faculty Scholarship

One of the most important recent developments in American legal theory is the burgeoning interest in "popular constitutionalism." One of the most important features of the American legal system is the selection of state judges – judges who resolve thousands of state and federal constitutional questions each year – by popular election. Although a large literature addresses each of these subjects, scholarship has rarely bridged the two. Hardly anyone has evaluated judicial elections in light of popular constitutionalism, or vice versa.

This Article undertakes that thought experiment. Conceptualizing judicial elections as instruments of popular constitutionalism, the Article aims to show, …

Three Essays On The Determinants Of Foreign Direct Investment (Fdi), Haitao Liang

Dissertations, Theses, and Capstone Projects

At first, a literature review of over 150 articles on the determination of Foreign Direct Investment (FDI) proposes the main determinants of FDI. A meta-analysis tests the reliability of the previous studies on FDI.

Then, a cluster analysis on FDI data reveals the necessary to segment economies, especially by income level, in FDI analysis.

A large number of studies emphasize FDI determinants but ignore the income distribution on the results, which biases the estimates. In Chapter 3, I correct for heterogeneity due to income distribution by using the Blundell-Bond System GMM (Generalized Method of Moments), which controls for endogeneity problem …
