Recommendations For The Chamlidere Petrified Forest Management Plan, Fatma Ertem

Graduate Theses and Dissertations

Anything inherited from our ancestors or from nature can be considered as our heritage. Heritage can be classified as cultural and natural heritage. Turkey has been the cradle of many civilizations, religions, and ethnic groups because of the unprecedented natural heritage and critical geopolitical location of Anatolia. Given all the treasure of cultural and natural heritage in Turkey, heritage management practices have not been emphasized as they deserve. A petrified forest was found in Chamlidere, Ankara (Turkey) in 2004. Chamlidere petrified forest preserves information related to the biodiversity of forests in the Galatian Volcanic Province during the Early-Middle Miocene. When …

Tryptophan Anchored Peptides In Lipid Bilayer Membranes: Control Of Peptide Orientation And The Phase Behavior Of Cholesterol-Containing Ternary Lipid Mixtures, Johanna Maria Rankenberg

Graduate Theses and Dissertations

Model WALP peptides and "next generation" WALP-derived hydrophobic model peptides were employed to discover principles that govern protein-lipid interactions in biological membranes.

Ternary cholesterol-containing lipid mixtures were examined in the presence of WALP peptides of different lengths (acetyl-GWW(LA)_nLWWA-ethanolamide, with n between 3 and 8). Deuterium NMR spectra from labeled lipids reveal that WALP peptides may stabilize lipid ordered "raft" domains and therefore promote lipid phase separation, albeit to a minor extent. The results depend upon whether dioleolyl- or diphytanoyl-phosphatidylcholine is present as the fluid lipid component.

Several WALP peptides were modified to remove anchoring Trp residues from one …

Multi-Threshold Cmos Circuit Design Methodology From 2d To 3d, Ross Josiah Thian

Graduate Theses and Dissertations

A new and exciting approach in digital IC design in order to accommodate the Moore's law is 3D chip stacking. Chip stacking offers more transistors per chip, reduced wire lengths, and increased memory access bandwidths. This thesis demonstrates that traditional 2D design flow can be adapted for 3D chip stacking. 3D chip stacking has a serious drawback: heat generation. Die-on-die architecture reduces exposed surface area for heat dissipation. In order to reduce heat generation, a low power technique named Multi-Threshold CMOS (MTCMOS) was incorporated in this work. MTCMOS required designing a power management unit (to control when and which gates …

A Methodology For Implementing Rf Bists In Production Testing To Replace Rf Conventional Tests, Deepa Mannath

Graduate Theses and Dissertations

Production testing of Radio Frequency (RF) devices is challenging due to the complex nature of the tests that have to be performed to verify functionality. In this dissertation a methodology to replace the complex and expensive RF functional tests with defect-oriented Built-in Self Tests (BiSTs) is detailed. If a design has sufficient margin to RF specifications then RF tests can be replaced with structural tests using a new data analysis technique called quadrant analysis, which is presented. Data from the analysis of over one million production units of said System on Chip (SoC) is presented along with the results of …

Graduate Theses and Dissertations

During their life, humans are exposed to numerous substances that are naturally present in the environment or that are the result of man made processes, including heavy metals, persistent organic pollutants, pesticides and veterinary drugs. Some of these substances can leave residues in food products and possibly expose consumers to their potential toxic effects. To address these problems extensive regulatory efforts are devoted to prevent, detect and control these substances from reaching the food supply. However, given the vast diversity of food products that requires monitoring and the immense diversity of potential chemical contaminants, the need for an efficient and …

Hardware Microkernels - A Novel Method For Constructing Operating Systems For Heterogeneous Multi-Core Platforms, Jason M. Agron

Graduate Theses and Dissertations

Today's standard operating systems (OSes) do not have the proper structure, nor support for executing on heterogeneous multi- and many-core platforms. These deficiencies manifest in symptomatic issues that range from relatively low-level application binary interface (ABI) compatibility problems, to higher-level concerns such as application programmer interface (API) compatibility, synchronization, and caching issues. These issues in turn reflect back up to the programmer through a lack of a standard set of OS services. Non-uniformities in the hardware architecture are also reflected back into the programming model. In total these issues combined break down the most fundamental benefit of modern operating systems; …

Eucharist: Prayer, Communion, Unity, Jeremy A. Helmes

Graduate Theses and Dissertations

The purpose of this thesis is to assert the theological connection between the Eucharistic Prayer and sacramental Communion. On this basis it argues that the Eucharistic Prayer ritually functions as the “heart” and “center” of the Mass, while the reception of sacramental Communion, specifically the Communion Procession, is more properly described as the ritual “summit” of the Eucharistic liturgy. It also emphasizes that the unity of the Body of Christ is the ultimate purpose of the Eucharist, which is deepened by the reception of sacramental Communion. This vital relationship between Eucharistic praying and Eucharistic Communion is in need of additional …

New Infrared Spectral Data For 27 Asteroids: An Investigation Of Meteorite-Asteroid Relationships By Using The Modified Gaussian Model, Katherine Marie Gietzen

Graduate Theses and Dissertations

Asteroids provide unique insights into the origin and early history of the solar system. Since asteroids are considered to be fairly pristine, studying them provides opportunities to learn more about the primordial solar system, its materials, processes and history. Since the discovery in 1801 of the first asteroid, Ceres, during the era when everyone was searching for the "missing planet", astronomers have been trying to understand what they are, where they came from, why they exist and what they can tell us about how our solar system formed and evolved.

Within the asteroid population are a number of sub-populations, the …

Applications Of Variable Number Tandem Repeat Genotyping In The Validation Of An Animal Medical Model And Gene Flow Studies In Threatened Populations Of Reptiles, Candace D. Smith

Graduate Theses and Dissertations

We used variable number tandem repeats (VNTR) to validate the chicken as a human medical model for Pulmonary Arterial Hypertension. We identified seven regions on four chromosomes and interrogated for VNTR markers that significantly associate with Pulmonary Hypertension Syndrome/ascites. In those regions, we identified 7 candidate genes; AGTR1, ACE, p38MAPK, SST, 5HT2B, NET1, and CALM3 for further analysis as significantly contributing QTL for ascites/PHS. We also used variable number tandem repeats to measure gene flow and gather evidence for multiple paternity in a population of Timber rattlesnakes, Crotalus horridus. We were able to verify 1 VNTR that can be used …

Factors Affecting Redox Magnetohydrodynamics For Flow In Small Volumes, Matthew D. Gerner

Graduate Theses and Dissertations

Lab-on-a-chip technologies offer the possibility of developing analytical devices that are low-cost, portable, disposable, fast, and operable by non-technical personnel. Such devices require automated methods to manipulate ultra-small volumes (picoliters) of samples and solution, including pumping, stirring, and positioning. Current methods for ultra-small volume microfluidics have limitations that restrict their use including high voltage requirements, disadvantageous flow profiles or rates, and relatively complicated fabrication due to mechanical parts. Redox magnetohydrodyanmics (RMHD) that utilizes permanent magnets for portability shows promise as a micropump with ease of switching flow direction, no moving parts, compatibility with both aqueous and non-aqueous solutions, low voltages …

Talking Us Into War: Problem Definition By Presidents Lyndon B. Johnson And George W. Bush, Barbara Ellen May Warner

Graduate Theses and Dissertations

How presidents talk us into war merges the study of problem definition in public policy with the study of rhetoric in communications. Using both qualitative and quantitative methods, this research analyzes the key words used by two presidents, Lyndon B. Johnson and George W. Bush, to persuade us into escalating a war in Vietnam and engaging in a pre-emptive war in Iraq, respectively. The findings indicate that presidents repeat words that are patriotic, emotive, metaphorical, symbolic and religious, tapping into American themes of Manifest Destiny and even predicting dire outcomes if we do not accept their definitions of the dangers …

Evaluating The Policies That Lead To Substantial Tuition Variation At Public Land-Grant Universities, Brent Alexander Burgess

Graduate Theses and Dissertations

Since the 1980's, the tuition at public colleges and universities has increased at a rate far beyond that of normal inflation. During this period, many public institutions have increased their tuitions exponentially, while others have chosen or been able to retain stable and relatively inexpensive tuition rates. The aim of this study was to examine what policies and external trends are responsible for public institutions having such wide variation in their tuition costs. Therefore, this study isolated one type of public institution, which was land-grant universities, that have a mission and tradition of providing affordable educations to examine the causes …

Understanding The Role Of Histones During Chromosome Segregation: A Study Of The Effects Of Histone Gene Dosage In Saccharomyces Cerevisiae, Rebecca Leigh Danforth

Graduate Theses and Dissertations

Chromatin plays a role in all cellular functions that involve DNA. These include, but are not limited to replication, recombination, transcription, and chromosome segregation. Chromosome segregation is an extremely well conserved cellular process and is essential for maintaining the genetic integrity of a cell. There is very strong evidence indicating that chromatin structure is critical for maintaining the fidelity of chromosome transmission, but its specific role(s) in this process remains unclear. Chromatin is comprised of arrays of nucleosomes that serve to compact DNA. These nucleosomes consist of 146 bp of DNA that is wrapped around a histone octamer; two each …

Imaging Second-Harmonic Radiation And Scattering Patterns In Zno Micro/Nanostructures, Katrina Marie Geren

Graduate Theses and Dissertations

The optical characteristics of ZnO nanostructures have recently garnered interest due to the inclusion of these structures in many nanoscale optical and optoelectronic devices. This thesis will address several characteristics involving second harmonic generation and scattering in ZnO nano- and microstructures. A method will be presented for determining the nonlinear coefficients of the second order susceptibility in a single ZnO rod. This method uses transmission geometry where previous methods have employed back-reflected irradiation. The nonlinear coefficients found using this new technique were consistent with previous data from similar structures. Models will be presented for predicting the second harmonic scattering patterns …

Modeling Of Compositionally Graded Barium Strontium Titanate From First Principles, Laura Elizabeth Walizer

Graduate Theses and Dissertations

"Barium Strontium Titanate (BaxSr1-xTiO3 or BST) is a Perovskite alloy of interest for both technological and intellectual reasons. Its ferroelectric and piezoelectric properties make it useful in a variety of electric components such as transducers and actuators, and BST in particular is a material of interest for the development of a ferroelectric RAM for computers. The inclusion of SrTiO3, an incipient ferroelectric, and the fact that the properties of a BST system depend strongly on its relative composition of BaTiO3 and SrTiO3 (ST), make also this a material of high interest. Compositionally graded systems are of further interest , partly …

Study Of Mercury Transformation With Chlorinated Species Under Homogeneous And Heterogeneous Conditions, Bhargavi Busireddy

Graduate Theses and Dissertations

Mercury (Hg) transformation under homogeneous (gas-phase oxidation reactions primarily involving chlorine species in flue gases) and heterogeneous (gas-surface oxidation reactions involving surface enhanced Hg oxidation in the presence of flue gases) environments were investigated. Gas phase experiments were performed in the presence of chlorine sources such as Cl2 and HCl. A large body of literature studies indicates that during combustion in coal-fired power plants coal mineral matter components play a major role in Hg transformation. Surface activity of these components with respect to Hg adsorption and overall Hg removal were evaluated using a laboratory-scale, fixed bed flow reactor where initial …
