Cortical Stimulation Mapping Of Heschl’S Gyrus In The Auditory Cortex For Tinnitus Treatment, Austin Huang Dec 2018

Cortical Stimulation Mapping Of Heschl’S Gyrus In The Auditory Cortex For Tinnitus Treatment, Austin Huang

CMC Senior Theses

Tinnitus is the perception of sound in the absence of an actual sound stimulus. Recent developments have shifted the focus to the central nervous system and the neural correlate of tinnitus. Broadly, tinnitus involves cortical map rearrangement, pathological neural synchrony, and increased spontaneous firing rates. Various cortical regions, such as Heschl’s gyrus in the auditory cortex, have been found to be associated with different aspects of tinnitus, such as perception and loudness. I propose a cortical stimulation mapping study of Heschl’s gyrus using a depth and subdural electrode montage to conduct electrocorticography. This study would provide high-resolution data ...


Synthesis Of Peg-Modified Guanine For Modulation Of Transcription Via Xpt-Pbux Riboswitch, Leah Santana Dec 2018

Synthesis Of Peg-Modified Guanine For Modulation Of Transcription Via Xpt-Pbux Riboswitch, Leah Santana

Senior Projects Spring 2019

Riboswitches are RNA molecules which respond to specific stimuli by turning on or off transcription or translation. The aptamer domain of the xpt-pbuX riboswitch in B. subtilis has a three-dimensional structure with a specific binding site for guanine. When guanine is bound, the expression platform forms a three-dimensional structure which inhibits transcription of downstream purine synthesis genes. In this work, polyethylene glycol (PEG) was conjugated to position nine of guanine. This will potentially increase the solubility of guanine in solvents such as dimethyl sulfoxide, making it easier to use for assays. The PEGylated guanine will be used to probe the ...

The Power Of Water: Examining Ice Crystal Nucleation’S Impact On Cloud Thermodynamic Properties, Caleb Wood

Meteorology Senior Theses

Cloud systems demonstrate great influence on Earth’s climate with both radiative and precipitation processes. However, detailed convection can be poorly represented in global climate models. By resolving fine-scale features, like cloud ice crystal nucleation, an improved understanding of the microphysics involved with deep convection will aid to more accurate incorporations of cloud systems into climate models. The purpose of this study is to analyze the differences in certain cloud thermodynamic properties, including mixing ratios and latent heat budgets, as a result of various ice nucleation cases. The Clark-Hall Cloud-Resolving Model (CRM) was initialized with observations from the 1997 Atmospheric ...

Numerical Simulations Of Premixed Flames Of Multi Component Fuels/Air Mixtures And Their Applications, Essa Kh I J Salem

Theses and Dissertations--Mechanical Engineering

Combustion has been used for a long time as a means of energy extraction. However, in the recent years there has been further increase in air pollution, through pollutants such as nitrogen oxides, acid rain etc. To solve this problem, there is a need to reduce carbon and nitrogen oxides through lean burning, fuel dilution and usage of bi-product fuel gases. A numerical analysis has been carried out to investigate the effectiveness of several reduced mechanisms, in terms of computational time and accuracy. The cases were tested for the combustion of hydrocarbons diluted with hydrogen, syngas, and bi-product fuel in ...


Gerrymandering And The Impossibility Of Fair Districting Systems, Danielle Degutz Dec 2018

Gerrymandering And The Impossibility Of Fair Districting Systems, Danielle Degutz

Senior Projects Spring 2019

Voting district boundaries are often manipulated, or gerrymandered, by politicians in order to give one group of voters an unfair advantage over another during elections. To make sure a system of voting districts is not gerrymandered, the population size, the shape, and the voting efficiency of each party in each district should be taken into consideration. Following recent work of Boris Alexeev and Dustin G. Mixon, we discuss mathematical criteria for each of these three aspects, and we prove how problems arise when attempting to apply all three at once to a districting system--first to a simplified districting system and ...


Biotech Fever: Market Overreaction To Fda Clinical Trials, Ethan J. Hugstad Dec 2018

Biotech Fever: Market Overreaction To Fda Clinical Trials, Ethan J. Hugstad

Honors Program Theses

Picture this: someone buys the stock of a firm that is about to announce the results of a drug’s FDA clinical trial the next day. They go to bed that night, imagining the potential of their newly owned business to finally cure a disease that has impacted so many families. They wake up the next morning to find that the firm has lost half of its market value because the drug failed. This is the stark reality that many small investors face: the unpredictability of price movements in response to nonfinancial information being released to the public.


Watermelon Cold Stress Testing For Cold Intolerant Seeds, Sarah Ebert Dec 2018

Watermelon Cold Stress Testing For Cold Intolerant Seeds, Sarah Ebert

Creative Components

Watermelon sales and production for Company X is a lucrative business. Watermelon is scientifically known as Citrullus lanatus (Thunb.) Matsum. & Nakai. Watermelon sales for Company X are directed to Georgia, Florida and Spain. These areas make up 80% of Company X’s watermelon seed sales. One major stress factor in these areas is low temperature during watermelon transplant season. Growers interested in selling their produce at the fall harvest markets must transplant the seedlings between February and April. This creative component outlines how watermelon transplants are produced in greenhouses, and what growing conditions are necessary in a field environment. It also outlines temperature trends and fluctuations in the targeted areas of Georgia, Florida and Spain. The cold stress testing has been historically used to help predict seed lot performance in the field in cooler climates and can be used to predict performance in potentially cold climates like Georgia, North Florida and Spain. Company X was interested in developing their own cold stress test to screen seed lots for cold susceptibility and to reduce bad emergence claims for the company. The objective of this project was to develop a test for screening seed lots based on germination and growth in cold temperatures. The road to this test took several steps from prescreening 47 watermelon seed lots to growing watermelon seeds in greenhouses to mimic cold conditions. A difference between primed and unprimed seed lots was observed throughout this experiment. Primed seeds are seed treated with a seed-germination-enhancement treatment. Primed seeds are thus at the same stage of physiological activation and germinate uniformly. Unprimed seeds do not undergo this process; therefore, unprimed seeds germinate at different rates due to different maturity levels and seeds ability to absorb water for imbibition. Ultimately thresholds for mean germination rate in primed seeds were set to identify seed lots that were cold tolerant and help direct the sales of primed seeds. Unprimed watermelon seeds performed differently and required a different testing protocol to help predict poor emergence in cold conditions. Ideally, unprimed seeds would not be sold to potentially colder climates. However, due to ...


“I’M The Greatest”: Pride, Impression Management, And Denial Of Coercive Control And Physical Abuse By Perpetrators Of Intimate Partner Violence, Benjamin Reissman, Kendra Doychak M.A., Angela Crossman Ph.D., Chitra Raghavan Ph.D. Dec 2018

“I’M The Greatest”: Pride, Impression Management, And Denial Of Coercive Control And Physical Abuse By Perpetrators Of Intimate Partner Violence, Benjamin Reissman, Kendra Doychak M.A., Angela Crossman Ph.D., Chitra Raghavan Ph.D.

Student Theses

Coercive control and physical abuse are two prominent forms of intimate partner violence (IPV), often accompanied by with impression management to conceal such behavior. However, intrinsic motives for engaging in impression management by male IPV offenders are not well-known. The present study makes use of archival data from 85 heterosexual men in a batterer treatment program to gauge how pride, shame, and guilt may relate to impression management and reported IPV. Admission to shame and guilt appear to be correlated with and predictive of both forms of reported abuse, along with the absence of impression management. This implies that internalized ...

The Charge Of Deserting Their Sphere: The Boston Female Anti-Slavery Society And Women’S Place In The Abolitionist Movement, Megan Irene Brady Dec 2018

The Charge Of Deserting Their Sphere: The Boston Female Anti-Slavery Society And Women’S Place In The Abolitionist Movement, Megan Irene Brady

Graduate Masters Theses

Responding to the all-male American Anti-Slavery Society and inspired by the expansion of women’s benevolent organizations, the Boston Female Anti-Slavery Society (BFAS) was founded in 1833. At the outset, the members defined themselves as pious women dedicated to immediate emancipation, while making no overtures to challenging their place in society. BFAS grew quickly in influence and membership, and helped organize the first national women’s anti-slavery convention in 1837. The convention brought together female abolitionists from all over the United States, some of whom espoused more radical views on women’s rights. This thesis examines how interactions at the ...

A View From Within: Notes And Insight From An Institutional Ethnography Of The National Commission For Natural Protected Areas In Tulum, Mexico, Maxwell J. Martin

Graduate Masters Theses

National parks and protected areas are an integral component of the Mexican government’s long-term natural resource conservation strategy. They comprise over 90 million hectares throughout the country. However, the establishment and upkeep of these protected areas often incites conflict both between and among local actors. From poachers taking protected resources to indigenous peoples exercising their rights, protected areas have become a source of political, economic, and moral contention across the globe. In addition, their effectiveness in either ecological or sustainable development terms has been ambiguous at best.

Tulum, Mexico exemplifies this dilemma. The site of pre-Columbian Mayan architecture, Tulum ...
