Two Essays in International Banking and Finance

Lin, Dongyun (2009-10-21)

This dissertation consists of two essays in international finance and banking. The first essay attempts to evaluate factors that promote or impede cross-border bank mergers and acquisitions using logistic regressions. The ...

Two Iron-Sulfur Proteins Involved in Isoprenoid Biosynthesis with New Catalytic Roles

Xu, Weiya (2010-08-05)

(E)-4-hydroxy-3-methylbut-2-enyl diphosphate synthase (GcpE or IspG) and (E)-4-hydroxy-3-methylbut-2-enyl diphosphate reductase (LytB or IspH) are involved in the last two steps of the DOXP pathway for isoprenoid biosynthesis. ...

Two Novel Relaxation Oscillator Interface Circuits for Resistive and Capacitive Sensors

Hatfield, Emily (2023-11-27) ETD File Embargoed

Presented in this thesis is the design and testing of two novel interface circuits for capacitive and resistive sensors. In both cases, the interface circuit is a modified CMOS inverter based relaxation oscillator, which ...

Two-dimensional (2D) MXene as the Building Block of Three-dimensional (3D) Ordered Electrode Architectures and Their Application in Energy Storage Systems

Orangi, Jafar (2020-12-01)

Transition metal carbides and nitrides (MXenes) are an emerging class of two-dimensional (2D) materials with interesting properties that have gained enormous attention since their discovery in 2011. Extensive theoretical ...

TWO-PART MASTER’S THESIS PART ONE: EVALUATION OF COOL ROOF REFLECTIVITY IMPACTS PART TWO: SURFACE SKIMMER FLOW RATES

Sharpe, Collin (2022-05-04)

PART ONE: Cool roofs attempt to lower the temperature of the roof surface so that the interior of buildings can be cooled using less energy. Light color surfaces, white being the coolest color, are much cooler than darker ...

Two-year Bark and Ambrosia Beetle Diversity Study at the Talladega National Forest in the Southeastern United States

Thompson, Jacob (2011-05-16)

Over two year period (March 2008 to February 2010), bark and ambrosia beetles were captured in three different trap types (intercept panel, flight intercept and pitfall) at the Talladega National Forest in Chilton, Bill ...

Typical Response of the ADXRS300 Microelectromechanical Systems (MEMS) Gyroscope in Acoustically Harsh Environments

Castro, Simon (2009-08-03)

In this thesis, the basic theory behind vibratory MEMS gyroscopes will be discussed to show how some of the design parameters originate. Also, a survey of commercially available MEMS gyros will be presented. In addition, ...

Typologies of childhood experiences and systemic lupus erythematosus disease activity, depression, and anxiety in the Black Women’s Experiences Living with Lupus (BeWELL) Study

Chung, Kara (2020-07-10) ETD File Embargoed

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that is sensitive to stress. However, there is a paucity of research on the impact of childhood stress on adult health among this population. This study ...

U-Th Dating of Zircons from a Holocene Volcanic Eruption (Dayingshan Volcano, Tengchong Volcanic Field): Insights into Magma Chamber Storage

Tucker, Ross (2011-05-02)

The Tengchong volcanic field is located along the southeastern margin of the Tibetan Plateau and has shown active volcanism throughout the Cenozoic. Only three volcanoes, however, have erupted more recently in the Holocene. ...
