The Effects Of Microstructure On The Mechanical Properties Of Hard Transition Metal Silicon Nitride Nanocomposite Coatings, Jessica Mooney Dec 2013

The Effects Of Microstructure On The Mechanical Properties Of Hard Transition Metal Silicon Nitride Nanocomposite Coatings, Jessica Mooney

Material Science and Engineering Dissertations - Archive

In this body of work, the examination of two different transition metal silicon nitride (MeSiN) systems using two different methods of physical vapor deposition (PVD) allowed for the development of a detailed understanding between the processing conditions, the micro-scale and nano-scale morphology, and the mechanical properties of the as-deposited thin film nanocomposite coatings. TiSiN coatings processed using the high-energy Arc deposition technique had hardness values of up to 33.6 GPa, and a previously unidentified (TiSi)N FCC crystalline phase, likely present due to the amounts of energy employed during coating processing, was discovered via intensive low angle X-Ray diffraction (XRD) and …

Oxidation Of Dibenzothiophene To Dibenzothiophene Sulfone Using Tungsten (Vi) Oxide, Alejandrina Rivera Dec 2013

Oxidation Of Dibenzothiophene To Dibenzothiophene Sulfone Using Tungsten (Vi) Oxide, Alejandrina Rivera

Theses and Dissertations - UTB/UTPA

The oxidation of dibenzothiophene (DBT) to dibenzothiophene-sulfone has been considered as an alternate method to remove sulfur from crude oil. This study demonstrates that the oxidative desulfurization (ODS) of DBT to DBT-sulfone occurs using WO3 as a catalyst. WO3 was synthesized and characterized using X-ray diffraction to determine the phase of WO3. Each reaction was refluxed and run for four hours using WO3 as a catalyst, dibenzothiphene, and four different solvents: decahydronapthalene, n-dodecane, decalin, and dodecane. The reactions were performed at temperatures ranging from 120 oC to 150 oC. Aliquots were taken at 30 minutes for up to four hours …

The Relational Algebra Toolkit: A User-Friendly Approach To Presenting And Processing Relational Algebra Queries On The Web, Jeremy J. Miller Dec 2013

The Relational Algebra Toolkit: A User-Friendly Approach To Presenting And Processing Relational Algebra Queries On The Web, Jeremy J. Miller

Theses and Dissertations - UTB/UTPA

Relational algebra is the mathematical basis of tools to express and optimize queries on relational data. However, there exists no convenient way to directly use, express, store, render, visualize, and execute relational algebra over the Web. Educators and practitioners are limited to creating relational algebra expressions using TeX or equation editors which cannot execute them. This work presents a solution to this issue: the Relational Algebra Toolkit (RAT). Relational data and queries are represented using purpose-built XML vocabularies, to be both machine-processable and serializable. Encoded relational algebra expressions can be rendered as parenthetical expressions and as syntax trees, translated to …

Evaluating Flexibility In International Patent Law, Sarah R. Wasserman Rajec Dec 2013

Evaluating Flexibility In International Patent Law, Sarah R. Wasserman Rajec

UC Law Journal

Global patent law has raced toward harmonization over the past decades. Countries with vastly different industries, values, and levels of development now offer robust patent rights with similar contours through membership in the World Trade Organization and consequent adoption of the Agreement on Trade-Related Aspects of Intellectual Property Rights (“TRIPS”). However, patent law is still far from harmonized among countries or static within countries. Jurisdictions tailor their patent laws to accommodate differences between industries, unforeseen inefficiencies, and diverse views of the costs and benefits associated with offering patent rights to stimulate innovation. Prior scholarly work consists of either doctrinal analyses …

Note – The True Man & The Battered Woman: Prospects For Gender Neutral Narratives In Self-Defense Doctrines, Katelyn E. Keegan Dec 2013

Note – The True Man & The Battered Woman: Prospects For Gender Neutral Narratives In Self-Defense Doctrines, Katelyn E. Keegan

UC Law Journal

The recent rise of controversial Stand Your Ground laws has sparked discussions on self-defense law. Comparing the new Stand Your Ground laws with another self- defense doctrine—Battered Women’s Syndrome—it becomes apparent that the law solidifies gender stereotypes by assessing when an individual is justified in using deadly force against an aggressor. “True men” are empowered to use deadly force in public without a duty to retreat, while a battered woman often must provide expert testimony on her psychological condition to prove the reasonableness of her use of deadly force in light of her severe helplessness. At their extremes, both of …

Defying Binaries: A Critical Examination Of 'Old' Versus 'New' In The Art Of Pablita Velarde And Helen Hardin, Jenna M. Kloeppel Dec 2013

Defying Binaries: A Critical Examination Of 'Old' Versus 'New' In The Art Of Pablita Velarde And Helen Hardin, Jenna M. Kloeppel

Art & Art History ETDs

Santa Clara painter Pablita Velarde and her artist daughter, Helen Hardin, are often discussed in both popular and academic literature as being representative, respectively, of two very different artistic traditions. Velardes art is commonly viewed as very much a product of her Dorothy Dunn-trained Santa Fe Studio background, and Hardin is seen as an avant-garde, wholly innovative artistic force representative of the generation of Native artists more aligned with the anti-Studio philosophies of the Institute of American Indian Arts, which was developing as Hardin was beginning her career in painting. This thesis will examine the modes of representation that have …

Lithostratigraphic And Petrophysical Analysis Of The Middle Devonian Marcellus Shale At The Mamont Prospect, Westmoreland County, Pennsylvania, Ty Taylor Dec 2013

Lithostratigraphic And Petrophysical Analysis Of The Middle Devonian Marcellus Shale At The Mamont Prospect, Westmoreland County, Pennsylvania, Ty Taylor

All Theses

The organic-rich Middle Devonian Marcellus Shale of the Appalachian basin is a rapidly developing natural gas play. Stratigraphic boundaries of the Marcellus Shale in Westmoreland County, Pennsylvania were identified using geophysical logs from 10 vertical gas-producing wells in a 23 sq. km area. Gamma-ray, bulk density, and resistivity well logs were examined to assess hydrocarbon potential. Values of porosity, total organic carbon (TOC), and water saturation (SW) were derived and mapped by incorporating well-log data into Marcellus-specific formulas. Gamma-ray, penetration (minutes per foot drilled), and mud-logging gas (total gas) from 12 horizontal wells from within the study area were also …

Pavement Evaluation Of The Concrete Tie-Bars And Dowel Baskets On Irvin Cobb Drive, Us 60, Mccracken County, Ky, Brad W. Rister, Jamie Creech, Joe Whelan, Timothy R. B. Taylor

Kentucky Transportation Center Research Report

A 1500 Mhz. ground coupled, ground penetrating radar antenna was used to identify both the horizontal alignment and the vertical displacement of the concrete tie-bars and the transverse joint dowel bar assembles on a Portland-Cement-Concrete-Pavement (PCCP) on US 60 in McCracken County, KY. Approximately 5 lanes miles of PCCP were evaluated using the 1500 Mhz. ground coupled antenna. Results indicate that only one transverse dowel basket out of an approximate total of 1,760 were within 4.17 inches of the pavement surface. Seven transverse dowel baskets were misaligned four inches or greater from the location of the sawed joint. These areas …
