Description
Analysing and measuring of biological or biochemical processes are of utmost importance for medical, biological and biotechnological applications. Point of care diagnostic system, composing of biosensors, have promising applications for providing cheap, accurate and portable diagnosis. Owing to these expanding medical applications and advances made by semiconductor industry biosensors have seen a tremendous growth in the past few decades. Also emergence of microfluidics and non-invasive biosensing applications are other marker propellers. Analyzing biological signals using transducers is difficult due to the challenges in interfacing an electronic system to the biological environment. Detection limit, detection time, dynamic range, specificity to the analyte, sensitivity and reliability of these devices are some of the challenges in developing and integrating these devices. Significant amount of research in the field of biosensors has been focused on improving the design, fabrication process and their integration with microfluidics to address these challenges. This work presents new techniques, design and systems to improve the interface between the electronic system and the biological environment. This dissertation uses CMOS circuit design to improve the reliability of these devices. Also this work addresses the challenges in designing the electronic system used for processing the output of the transducer, which converts biological signal into electronic signal.

Description
MESFETs are used in high frequency applications and are typically made from GaAs. Dr. Trevor Thornton designed a silicon-on-insulator MESFET \u2014 a cheaper alternative with competitive capabilities. This paper concerns the characterization and modeling of this device to exhibit its marketability as a CMOS integrated transistor. Overviews of the MESFET's history and DLTS (deep level transient spectroscopy) are offered.

Description
An in depth look at the rhetoric behind the campus carry debate at the University of Texas at Austin. This thesis researched and examined primary sources from The Daily Texan and The Austin-American Statesman attempting to analyze what was at stake for both sides of the argument and what the most effective rhetorical tool was.

Description
The "no compromise" gun rights movement, which advocates against any form of gun control and the absolute right to keep and bear arms, and white Christian nationalism, a cultural framework built on the belief that Christianity should serve as the foundation of the American government, have both recently come to the national political forefront. The connection between these two movements runs deep: white Christian nationalism informs the religious rhetoric of the "no compromise" movement. To understand why this is, the existing scholarship argues that white Christian nationalists advocate against gun control because they believe the Second Amendment is divinely inspired and that gun control does not address what they perceive to be a moral decline in the United States. However, these explanations are insufficient to fully grasp the inherent importance of guns and gun rights to white Christian nationalists. Therefore, I examine the specific roles that guns play in their worldview.
