Preparing Medical Students To Counsel For Smoking Cessation, Aubree M. Guiffre

Graduate Theses, Dissertations, and Problem Reports (ETD)

Smoking is a national epidemic. Medical providers are the first line of defense to help patients reduce or stop smoking. However, smoking cessation counseling does not occur consistently or regularly. Medical providers must be trained to counsel for smoking cessation, with certain areas requiring attention in order for the training to be successful. There is a relationship between medical students who have high rates of self-efficacy related to smoking cessation counseling and high rates of actual counseling. Understanding the relationships between knowledge, skills, attitudes, and the medical school year in training on self-efficacy is important to better prepare medical students …

Optimization Of A Retrofit Urea-Scr System, Clinton R. Bedick

Graduate Theses, Dissertations, and Problem Reports (ETD)

Oxides of nitrogen (NOx) emissions from legacy diesel engines are often many times over currently mandated standards, contributing significantly to degradation of air quality and negative environmental impact. A retrofit urea-SCR (selective catalytic reduction) aftertreatment system offers a viable solution for reducing NOx emissions from older diesel engines. A stand-alone retrofit urea-SCR aftertreatment system was previously developed by West Virignia University (WVU) engineers, implementing a pre-SCR NOx sensor, open-loop feed-forward control, and stoichiometric NOx reduction logic. During experimental testing at WVU, the urea-SCR system demonstrated NOx reductions of 2% to 53%, depending on the test cycle. In order to optimize …

Weak Floor Stability In The Illinois Basin Underground Coal Mines, Murali M. Gadde

Graduate Theses, Dissertations, and Problem Reports (ETD)

The research described in this dissertation is a direct consequence of the author's quest to find solutions to several problems he faced while designing optimum pillar layouts for some Illinois Basin coal mines over weak immediate floor strata. When using the existing methods of floor stability analysis, conclusions were sometimes drawn that were either not supported by real-world mining experience or in some cases even physically impossible results were obtained. Therefore, it was necessary to delve deeper into the existing methods and understand their limitations to arrive at alternatives that were consistent with practical observations. In improving upon the existing …

The Fearful Face And Beyond: Fmri Studies Of The Human Amygdala, Jillian E. Hardee

Graduate Theses, Dissertations, and Problem Reports (ETD)

The amygdala has been labeled as a "detector of threat", evidenced by its heightened response to fearful faces in human neuroimaging studies. A critical element of the fearful face is an increase in eye white area, hypothesized to be crucial for the rapid detection of fear in another's face. Yet other facial expressions can also increase eye white area in a manner that is similar (a lateral shift in gaze) or identical (surprise) to fear. It is unknown if the amygdala can differentiate between these types of increases in eye white area and those that are specifically associated with fear …

Locomotion Grows Up: The Neuromechanical Control Of Interlimb Coordinating Mechanisms In Crayfish, Marc D. Rinehart

Graduate Theses, Dissertations, and Problem Reports (ETD)

Locomotion requires many dynamic interactions between organism and environment at several levels. It is not known how the nervous system controls all of these relationships to ultimately produce and guide locomotor behavior. Furthermore, it is not known whether the nervous system needs to recognize and control all of the possible body-environment interactions. In this study the crayfish (Procambarus clarkii) is used as a model system to test how size influences locomotor behavior and how a single, simplified neuromechanical system can accommodate these changes.;A set of behavioral experiments was conducted to characterize kinematics of freely walking juvenile crayfish to compare with …

Cybersieves, Derek E. Bambauer

Duke Law Journal

This Article offers a process-based method to assess Internet censorship that is compatible with different value sets about what content should be blocked. Whereas China's Internet censorship receives considerable attention, censorship in the United States and other democratic countries is largely ignored. The Internet is increasingly fragmented by nations' different value judgments about what content is unacceptable. Countries differ not in their intent to censor material-from political dissent in Iran to copyrighted songs in America-but in the content they target, how precisely they block it, and how involved their citizens are in these choices. Previous scholars have analyzed Internet censorship …

Pandemic Potential Of Reassortant Swine Influenza A Viruses, Christy Brockwell Staats

Theses and Dissertations (ETD)

Influenza A viruses are capable of causing disease in several species, including birds, humans and swine. Host specificity of the viruses is not absolute, and is influenced by a range of factors. Swine play a pivotal role in the interspecies transmission of influenza A viruses, as they are susceptible to infection with both human and avian strains and have been implicated as a “mixing vessel” for the reassortment of influenza A viruses from different species. The reassortment of influenza A viruses of human and avian origin led to human influenza pandemics in 1957 and 1968.

The dynamics of swine influenza …

Compact Trench-Based Silicon-On-Insulator Rib Waveguide Ring Resonator With Large Free Spectral Range, Seunghyun Kim, Gregory P. Nordin, Weisheng Hu, Yusheng Qian, Jiguo Song, Gregory L. Wojcik

Faculty Publications

We demonstrate a compact trench-based silicon-on-insulator (SOI) rib waveguide ring resonator comprised of trench-based bends and splitters. It has a perimeter of 50 μm and occupies an area of only 25×25 μm. The measured free spectral range (FSR) is 13.2 nm, which the largest reported for an SOI rib waveguide ring resonator. The measured FSR, full width at half maximum, and quality factor match reasonably well with analytical calculations. Further calculation shows that a FSR of 50.8 nm is achievable for an SOI rib waveguide ring resonator with a perimeter of 15 μm.

Population Ecology And Reproductive Biology Of The Diamondback Watersnake, Nerodia Rhombifer (Serpentes: Colubridae), In Southernmost Texas, Ruben D. Zamora

Theses and Dissertations - UTB/UTPA

Nerodia rhombifer is a polytypic, semi-aquatic snake with a broad geographical distribution ranging from the American Midwest southward to Chiapas, Mexico. Although relatively abundant throughout much of its range, few ecological studies of the species have been conducted. This study provides basic population ecology information in a subtropical habitat. Population data were obtained in a mark-recapture study at Santa Ana National Wildlife Refuge, Hidalgo County, Texas, from August 1995 to December 1998. Specimens taken elsewhere in Hidalgo County provided information on the reproductive biology. This study provides the first absolute density estimates from anywhere within the species’ range. Quantitative information …
