Not Got Milk? The Effect On The Gut Microbiome Of Removing Dairy From The Diet, Patrick Tyler Stovall
Not Got Milk? The Effect On The Gut Microbiome Of Removing Dairy From The Diet, Patrick Tyler Stovall
Honors Theses
The human gut contains a highly diverse set of bacteria that perform a wide range of duties that include much more than just nutrient acquisition. However, the composition of this community is subject to change, with diet, age and lifestyle playing roles in the development and maintenance of the gut microbiota. This study compared the bacterial composition of the human gut when consuming a normal diet versus a dairy-free diet. Samples were taken from a single subject during three periods: 1) control (normal) diet, 2) dairy-free diet, and 3) a return to normal diet. Gut bacterial communities were identified and …
Effects Of Large Induced Superconducting Gap On Semiconductor Majorana Nanowires, William S. Cole, S. Das Sarma, Tudor D. Stanescu
Effects Of Large Induced Superconducting Gap On Semiconductor Majorana Nanowires, William S. Cole, S. Das Sarma, Tudor D. Stanescu
Faculty & Staff Scholarship
With the recent achievement of extremely high-quality epitaxial interfaces between InAs nanowires and superconducting Al shells with strong superconductor-semiconductor tunnel coupling, a new regime of proximity-induced superconductivity in semiconductors can be explored where the induced gap may be similar in value to the bulk Al gap (large gap) with negligible subgap conductance (hard gap). We propose several experimentally relevant consequences of this large-gap strong-coupling regime for tunneling experiments, and we comment on the prospects of this regime for topological superconductivity. In particular, we show that the advantages of having a strong spin-orbit coupling and a large spin g-factor in the …

To Be, Or Not To Be-Statehood Is The Question: Analyzing The Islamic State In Syria And Iraq, Leigh Anne Zook
To Be, Or Not To Be-Statehood Is The Question: Analyzing The Islamic State In Syria And Iraq, Leigh Anne Zook
Honors Theses
On June 29, 2014, Abu Bakr al-Baghdadi officially declared the Islamic State in the Sham (ISIS) as an Islamic Caliphate, and consequently renamed his organization the Islamic State (IS). Over the course of 2014, the IS rose to garner significant international attention, which heightened following direct US military intervention in August 2014 in the form of airstrikes against the IS's targets located in Iraq. Determining if the IS qualifies as a state, from a US perspective, holds significant ramifications for future military and diplomatic interactions with this organization. This analysis brings to light the ongoing issues with appropriately and objectively …

China's 'Leftover' Women Phenomenon: Media Portrayal And 'Leftover' Voices, Mazie Merriman
China's 'Leftover' Women Phenomenon: Media Portrayal And 'Leftover' Voices, Mazie Merriman
Honors Theses
China's shengnü — or leftover women — are a group of highly-educated, single, urban women that the Chinese government has targeted in a scare-mongering media campaign intent on pushing these women to give up their careers or education in order to marry and produce children for the betterment of the state. Since 2007, this group of women has faced highly negative articles and images published both by the All China Women's Federation and other news outlets encouraging shengnü to fix their problems and marry. These highly-educated, unmarried women are seen as violators of traditional gen-der norms and roles, and the …

Para-Interface: A Novel Interface For Para-Aeh Software Suite, Michael Ginn
Honors Theses
Para-AEH is a software suite designed to the Asymptotic Expansion Homogenization method. This method is commonly used to model structures by using differential equations to represent larger structure from a smaller structure input. In order to facilitate the University of Mississippi's Department of Mechanical Engineering's research purposes the software needed to be installed. A novel interface was designed to remove the overhead of interacting with the software on a command line based level. The software allows the management of users that can access the software and jobs that package several commands together for asynchronous execution without manual intervention.
Regime Type And Healthcare Systems: A Global Quantitative Analysis, R. L. Barr
Regime Type And Healthcare Systems: A Global Quantitative Analysis, R. L. Barr
Honors Theses
This thesis examines the link between regime type and healthcare systems. After reviewing literature that examines regime type, social spending, and healthcare, as well as a more specific example of regime change in Chile, it undertakes a multivariate regression analysis of 183 countries. It concludes that democracies have significantly better healthcare-system indicators, but that environmental variables, such as Latitude and Percentage of Rural Population, are more significant predictors of healthcare. It concludes that, while regime type is an important factor, dealing with ecological and locational problems of a country, such as combating tropical diseases and expanding access to infrastructure, are …

Social Interaction Between Deaf And Hearing People, Rebecca C. Hankins
Honors Theses
This study examined the personal experiences of hearing people in their interactions with Deaf persons and their knowledge about Deaf culture. The research involved questioning hearing people about their perceptions and interactions with Deaf people and Deaf culture in an effort to gain insight as to how the lives of Deaf people can be improved in mainstream culture. It was predicted that a majority of hearing participants would describe a lack of knowledge about Deaf culture, discomfort interacting with a Deaf person, and an agreement that a need exists for better understanding of Deaf culture. A survey was conducted with …
Phylogeography Of The Australian Common Froglet, Crinia Signifera, Rosetta C. Williams
Phylogeography Of The Australian Common Froglet, Crinia Signifera, Rosetta C. Williams
Honors Theses
Australia is an ancient continent with equally antiquated fauna. Crinia signifera, the Australian common froglet, is one of Australia's oldest species and has a geographic range covering much of the southeastern coast of Australia and much of Tasmania. Such broad dispersal makes C. signifera susceptible to genetic variation due to changes in the landscape. While many have studied the morphology of C. signifera, few have studied its phylogeographic history. In this study I compared mitochondrial DNA clades to nuclear DNA clades to analyze the role geography plays on genetic variation. I hypothesized that (i) sympatric nuclear clades and subclades would …
Investigation Into The Initial Electric Field Change Of Lightning Flashes, Ryan Chapman
Investigation Into The Initial Electric Field Change Of Lightning Flashes, Ryan Chapman
Honors Theses
Previously, an initial electric field change (IEC) was found occurring before initial breakdown (IB) pulses by sensors within the reversal distance of 36 lightning flashes [Marshall et al. 2014]. The E-change for a CG flashes was positive within reversal distance, and the E-change for an IC flashes was negative. With this data in mind, an IEC is best defined as occurring from zero slope to gradual increase in E-change at the beginning of a lightning flash, and it ends with the first IB pulse. The purpose of this thesis is to extend said findings to further understand the characteristics of …
Effect Of Biochar And Activated Carbon Amendments On Gaseous Mercury Emissions Of Soil And Mercury Methylation Rates In Sediment, Ryan Sessums
Honors Theses
Mercury is a pervasive global contaminant with a complex biogeochemical cycle. In this biogeochemical cycle, methylmercury (MeHg+) tends to biomagnify and concentrate in fish and seafood consumed by humans. This study examines the effect of sorbent amendments on both the mercury emission from soils and the methylation rates of mercury in sediments, both of which are believed to be major contributors to the global cycle. Biochar and activated carbon were used to treat soils and sediments to explore their effects. It was found that biochar and activated carbon reduced gaseous mercury emission by 25% and 49%, respectively. Methylation rates in …
Effects Of Soil Environment On Abundance, Diversity And Community Structure Of Ectomycorrhizal Fungi In Pinus Radiata, Sarah C. Steele
Effects Of Soil Environment On Abundance, Diversity And Community Structure Of Ectomycorrhizal Fungi In Pinus Radiata, Sarah C. Steele
Honors Theses
Balanced and sustained nutrient cycles are critical to the success of the world's forest ecosystems. Research has shown ectomycorrhizal fungi (ECM) play a vital role in regulating these systems, as they store and mobilize cycled nutrients for the trees they colonize. Not all species of ECM allocate essential nutrients (nitrogen, phosphorous and carbon) to their host with the same efficiency. Studies have shown the soil environment is important for determining fungal distribution. To better understand the ECM fungal community of Pinus radiata, I explored the effects of soil characteristics (percent silt, percent clay, percent sand and soil water content) on …
The Effect Of Polyamines On I-Motif Thermal Stablity, Shelby Claire Liddell
The Effect Of Polyamines On I-Motif Thermal Stablity, Shelby Claire Liddell
Honors Theses
Polyamines are present inside cells at varying concentrations anywhere between 10 mM and 60 mM, and because of their molecular structure they contribute a positive charge to the interior of the cell. There has been previous evidence that the concentrations of polyamines have an effect on the stability of the DNA strands, which can affect the cellular processes. The particular DNA conformation studied is the i-motif, which is formed by intermolecular folding in cytosine rich strands. The i-motif studied is C20T, which is found in the promoter region of the oncogene, c-myc. Stabilization of c-myc can have an effect on …

The Effects Of Mouth Guards And Clenching On Strength And Power Measures Of A Countermovement Vertical Jump: A Pilot Study, Hannah M. Hudson
The Effects Of Mouth Guards And Clenching On Strength And Power Measures Of A Countermovement Vertical Jump: A Pilot Study, Hannah M. Hudson
Honors Theses
Strength and power gains from either mouth guards or clenching have been reported in highly trained athletes from a number of studies utilizing different testing measures. However, there have not been statistically significant effects in a recreationally trained population; and there has not been a research design to combine multiple mouthpiece conditions (mouthpiece designed for performance, a traditional mouth guard, and no mouthpiece condition) with a clench and no clench sub-condition. Therefore, the purpose of this study was to evaluate potential ergogenic effects of mouth guards and clenching on strength and power measures of a countermovement vertical jump. Three recreationally …
