Hydrophobicity of Magnetite Coating on Low Carbon Steel
Superhydrophobic coatings (SHC) with excellent self-cleaning and corrosion resistance property is developed on magnetite coated AISI SAE 1020 steel by using a simple immersion method. Roughness measurement, scanning electron microscopy (SEM), atomic force microscopy (AFM), X-ray diffraction (XRD), contact angle measurement (CAM), energy dispersive spectroscopy (EDS), Fourier transform infrared spectroscopy (FTIR), potentiodynamic polarization test, electrochemical impedance spectroscopy (EIS), and qualitative characterization of self-cleaning behavior, antifouling property and durability of the coatings are assessed. A water contact angle as high as 152o on the coated surface with excellent self-cleaning and resistivity to corrosion and good longevity in atmospheric air is obtained. Self-cleaning test results prove that these surfaces can find applications in large scale production of engineering materials. Potentiodynamic polarization tests and EIS tests confirm that the superhydrophobic low carbon steel surfaces have better resistance to corrosion compared to bare steel and magnetite coated steel in 3.5% NaCl solution. But the longevity of the coated steel surfaces in 3.5% salt solution is limited, which is revealed by the immersion durability test. However, hydrophobic coatings (HC) have better stability in normal tap water, and it can stay unharmed up to 15 days. Finally, hydrophobic coatings on low carbon steel surface retains hydrophobic …

U.S.-EU Trade and Economic Issues
This report discusses U.S.-EU trade and economic relations, which currently face heightened tension, particularly due to the Trump Administration's trade policy, which is focusing on unilateral tariff measures under U.S. trade law and taking a critical view of the U.S. role in international economic cooperation. Given U.S.-EU historical joint leadership on global trade and economic issues, these developments could have implications for the rules-based international trading system, a foundation of the global economic order that has contributed to global economic growth and stability in the post-World War II era.

Oil in Ghana: a curse or not? Examining environmental justice and the social process in policymaking
There is great expectation that oil development in Ghana will catapult the nation towards prosperity and lead to drastic improvement in the wellbeing of Ghanaians. However, there is also concern that Ghana could fail to achieve these due to the resource curse notwithstanding the fact that scholars of the curse have yet to agree on the inevitability of the curse. Resource curse scholars adduce different reasons for its occurrence or absence. One thing common among the scholars, however, is that none discusses environmental justice in the context of the curse. In this dissertation, I examine Ghana's attempts at avoiding the resource curse through policymaking and implementation using the Guidelines on Environmental Assessment and Management of Ghana's offshore oil sector as a case study. I argue that a strong environmental justice frame is required to avert the curse in Ghana. Specifically, I assess the policy process in Ghana's oil sector, the institutional framework for managing the sector, and analyze the perception of environmental justice for policymaking. The outcome of these assessments show that although the policy process requires broadening for full and effective participation, Ghana has checks and balances policies to avert the resource curse and to deliver environmental justice in …

Long-Term Citizen Science Water Monitoring Data: An Exploration of Accuracy over Space and Time
The Texas Stream Team (TST) is one of an increasing number of citizen science water monitoring programs throughout the US which have been continuously collecting surface water quality data under quality assurance protocols for decades. Volunteer monitoring efforts have generated monitoring datasets that are long-term, continuous, and cover a large geographic area - characteristics shown to be valuable for scientists and professional agencies. However, citizen science data has been of limited use to researchers due to concerns about the accuracy of data collected by volunteers, and the decades of water quality monitoring data collected by TST volunteers is not widely used, if at all. A growing body of studies have attempted to address accuracy concerns by comparing volunteer data to professional data, but this has rarely been done with large-scale, existing datasets like those collected by TST. This study assesses the accuracy of the volunteer water quality data collected across the state of Texas by the TST citizen science program between 1992-2017 by comparing it to professional data from corresponding stations during the same time period, as well as comparing existing and experimental data from a local TST partner agency. The results indicate that even large-scale, existing volunteer and professional …

Old Riot, New Ranger: Captain Jack Dean, Texas Ranger and U.S. Marshal
Access:
Use of this item is restricted to the UNT Community
Award-winning author Bob Alexander presents a biography of 20th-century Ranger Captain Jack Dean, who holds the distinction of being one of only five men to serve in both the Officer’s Corps of the Rangers and also as a President-appointed United States Marshal. Jack Dean’s service in Texas Ranger history occurred at a time when the institution was undergoing a philosophical revamping and restructuring, all hastened by America’s Civil Rights Movement, landmark decisions handed down by the United States Supreme Court, zooming advances in forensic technology, and focused efforts designed to diversify and professionalize the Rangers. His job choice caused him to circulate in the duplicitous underworld of dishonesty and criminality where twisted self-interest overrode compliance with societal norms. His biography is packed with true-crime calamities: double murders, single murders, negligent homicides, suicides, jailbreaks, manhunts, armed robberies and home invasions, kidnappings, public corruption, sexual assaults, illicit gambling, car-theft rings, dope smuggling, and arms trafficking. “Bob Alexander personally interviewed Jack Dean, a renowned Texas lawman who wore a badge for forty-three years. These conversations form the core of a well-researched and fascinating account of Lone Star justice from the mid-twentieth century into the new millennium.” —Darren L. Ivey, author of The Ranger …

Influence of Social Media on Decision Making of the Kuwait National Assembly Members: Case Study
In Kuwait, an increase in the use of social media by the Kuwait National Assembly (KNA) has allowed it members to reach out to the public and so advance their political agenda. This study examines social media influences on the decision making process; addresses the lack of academic research in relation to KNA members; and seeks to understand the extent to which public political engagement using social media might affect the outcome of their decision making. The proposed social media influence model (SMIM) was used to explore the relationships and relative importance of variables influencing legislator decision making in a social media environment. The second decade of the twenty-first century saw a number of major issues emerging in Kuwait. A core mixed method design known as explanatory sequential was applied to multiple sets of data generated during KNA members' 14th (2013-2016) and 15th (2016-2018) terms. These data included Twitter messages (tweets), the KNA Information Center Parliamentary Information System legislation documents, and the news media articles. The sample was drawn from KNA membership, some of which used Twitter to comment on major events with specific hashtags and the Kuwaiti news media articles related to the same. Study results confirm and support …

Exploring Growth Kinematics and Tuning Optical and Electronic Properties of Indium Antimonide Nanowires
This dissertation work is a study of the growth kinematics, synthesis strategies and intrinsic properties of InSb nanowires (NWs). The highlights of this work include a study of the effect of the growth parameters on the composition and crystallinity of NWs. A change in the temperature ramp-up rate as the substrate was heated to reach the NW growth temperature resulted in NWs that were either crystalline or amorphous. The as-grown NWs were found to have very different optical and electrical properties. The growth mechanism for crystalline NWs is the standard vapor-liquid-solid growth mechanism. This work proposes two possible growth mechanisms for amorphous NWs. The amorphous InSb NWs were found to be very sensitive to laser radiation and to heat treatment. Raman spectroscopy measurements on these NWs showed that intense laser light induced localized crystallization, most likely due to radiation induced annealing of defects in the region hit by the laser beam. Electron transport measurements revealed non-linear current-voltage characteristics that could not be explained by a Schottky diode behavior. Analysis of the experimental data showed that electrical conduction in this material is governed by space charge limited current (SCLC) in the high bias-field region and by Ohm's law in the low …

A random walk version of Robbins' problem: small horizon
This article considers an analogous problem in which the observed random variables are the steps of a symmetric random walk. Assuming continuously distributed step sizes, it describes the optimal stopping rules for the cases n = 2 and n = 3 in two versions of the problem: a "full information" version in which the actual steps of the random walk are disclosed to the decision maker; and a "partial information" version in which only the relative ranks of the positions taken by the random walk are observed. When n = 3, the optimal rule and expected rank depend on the distribution of the step sizes. The authors give sharp bounds for the optimal expected rank in the partial information version, and fairly sharp bounds in the full information version.
