Diamond Intracrystalline Stable Isotope Chemical Image Analysis By Time-Of-Flight Secondary Ionization Mass Spectrometery, Tyler J. Sundell
Diamond Intracrystalline Stable Isotope Chemical Image Analysis By Time-Of-Flight Secondary Ionization Mass Spectrometery, Tyler J. Sundell
MSU Graduate Theses
The chemical resistance of diamond allows in-situ study of the diamond source regions. For a majority of gem quality diamonds, this source region is the sublithospheric mantle keel of a cratonic nuclei. Through analysis of stable isotopes, radiogenic isotopes and trace elements, diamond geochemical analyses can define chemical fluxes in the mantle keel. However, such studies require multiple methodologies for each chemical suite, high spatial resolution and analytical precision. Here, I evaluate Time-of-Flight Secondary Ionization Mass Spectrometer (ToF-SIMS) as an alternative method for diamond geochemical analyses. ToF-SIMS analysis can perform in cation and anion mode to measure the entire periodic …

Effects Of Parafluvial Flows On Interstitial Ammonia And Freshwater Mussels In The Buffalo National River, David Alan Johnson
MSU Graduate Theses
Freshwater mussel populations and distributions have declined over the past several decades in the Buffalo River, Arkansas. Among many possible causes, this study tested the hypothesis that ammonia concentrations in parafluvial flows through gravel bars might be high enough to impair the survival and growth of juvenile mussels. Ammonia, pH, temperature, and dissolved oxygen were measured in interstitial and water column samples from gravel bars to test for possible longitudinal gradients. Samples were taken along 3 large bars at locations within the Buffalo National River, at approximate bi-weekly intervals between June and September of 2010. Water sample ammonia concentrations were …

Goji berry plants (Lycium barbarum L.) are grown across the globe for their berries and the health benefits that come from eating those berries. However, in Ningxia, China, Goji berry plants are also grown as a source of edible greens. In order to harvest the young green shoots, the plants are subjected to intense pruning and kept as a small, low-growing shrub. There is little information on this method of Goji berry management and greens production in the United States. The purpose of this research is to determine if Goji berry cultivars grown for berry production in the United …
How God Writes History: A Gramscian Analysis Of Religion And Nature In The Writings, Life, And Legacy Of John Muir, Daniel R. Jones
How God Writes History: A Gramscian Analysis Of Religion And Nature In The Writings, Life, And Legacy Of John Muir, Daniel R. Jones
MSU Graduate Theses
Representations of John Muir, America’s most famous environmentalist, and religion have been highly variegated. A mythological figure of American environmental politics, Muir and his legacy have been an ideological apparatus for presidents, environmentalists, and naturalists performing acts of identification for themselves and their country. Furthermore, religion and environmental scholars have often used Muir as a case study for what they call “nature religion.” Lost in this myth-making labor are the politics of sacred spaces and national discourse. Italian political theorist Antonio Gramsci developed the concept of common sense and the intellectual, which this thesis uses to analyze John Muir’s poetics …

Effects Of Irrigation On Forage Growth Rates On Rotational Grazing Dairies, Zachary Davis
Effects Of Irrigation On Forage Growth Rates On Rotational Grazing Dairies, Zachary Davis
MSU Graduate Theses
The amount and timing of rainfall in Missouri can be very irregular. This causes issues for producers of agronomic products in the state who rely on forages for income. The most sensible approach to the problem is the use of irrigation. But there is little useful information to reference when implementing this management decision. By studying three different styles of irrigation (center pivot, spider, and k-line) on 4 species of forages native to Missouri (alfalfa, crabgrass, perennial ryegrass, and tall fescue/clover), this study provides valuable insight as to the cost and benefit of irrigation. The main goal is to produce …

Tree Song, Amie Elizabeth Case
Tree Song, Amie Elizabeth Case
MSU Graduate Theses
The Grace that flows through the three realms is fractured, and it’s Mauhiyn’s fault. She is a Daughter, the only living and direct descendant of the line of women who are vessels for the Grace that sustains the realms in a state of perfect balance. Because Mauhiyn is the first Daughter unable to carry the Grace, she is blamed for the turmoil and darkness in the realms. King Darbrend of the western realm claims Mauhiyn’s Grace is simply dormant, not absent. Mauhiyn is sent to King Darbrend with the hopes that his dark power will restore the Grace within her …

Effects Of Calcium Fertilization On Growth, Yield, And Nutrient Content Of Hydroponically Grown Radish Microgreens, Cady C. Goble
MSU Graduate Theses
Radish microgreens were grown in a hydroponic wicking system and subjected to a range of calcium chloride (Ca) solutions to evaluate growth, yield, and mineral content. A solution range of 0 to 160 mM Ca was applied to determine upper limits of Ca fertilization. Solutions above 20 mM Ca showed toxic effects to germination and growth, while 5 and 10 mM Ca resulted in the greatest percent of shoots that grew to a desired size for harvest (%H), as well as greater average hypocotyl length per plant (HL) and cotyledon surface area per plant (CSA). For subsequent experiments, Ca solution …
Did Hollywood Take Theatre "By Hook Or By Crook?", Catherine S. Wright
Did Hollywood Take Theatre "By Hook Or By Crook?", Catherine S. Wright
MSU Graduate Theses
Hollywood and Theatre have been partners in producing entertainment for over 100 years. The relationship was fruitful for both parties, but Hollywood moguls and playwrights battled over ownership of the work and crafting of its creative nucleus, story and character. Theatre was the dominant entertainment right before the rise of motion pictures. Once Hollywood’s talkies closed the curtain on silent films, playwrights had a high creative worth to movie makers. In the cinema, story and dialogue were essential for its survival and growth. Playwrights were courted by the Hollywood studio heads but were not offered equal partnership as they were …

An Adaptive Memory-Based Reinforcement Learning Controller, Keith August Cissell
MSU Graduate Theses
Recently, the use of autonomous robots for exploration has drastically expanded--largely due to innovations in both hardware technology and the development of new artificial intelligence methods. The wide variety of robotic agents and operating environments has led to the creation of many unique control strategies that cater to each specific agent and their goal within an environment. Most control strategies are single purpose, meaning they are built from the ground up for each given operation. Here we present a single, reinforcement learning control solution for autonomous exploration intended to work across multiple agent types, goals, and environments. The solution presented …

The development of compact sensors in recent years has inspired the use of UAS-based hyperspectral and aerial imaging techniques for small-scale remote sensing applications. With increasing concerns about climate change, spectrally-derived vegetation indices (VIs) have proven useful for quantifying stress-induced vegetation response. The goal of this study was to develop predictive models and assess methodology for modeling the biological response of a black walnut -dominant mixed hardwood stand to seasonal climate events using UAV-based hyperspectral remote-sensing. The derived VIs were evaluated against the means of four seasonal measures of climate calculated for a two-week period prior to the flight date. …
The Impact Of Black Lives Matter Movement Publicity On Juror Decision Making, Emily R. Nerness
The Impact Of Black Lives Matter Movement Publicity On Juror Decision Making, Emily R. Nerness
MSU Graduate Theses
Others have investigated separately whether general pretrial publicity (PTP) or racial salience have an impact on juror decision making, but no one has explored a potential connection between the two. With information about the Black lives matter (BLM) movement recurring in the media, the question arises of whether news about the BLM movement can increase racial salience, thereby influencing juror decision making. The present research addressed whether 1) exposing participants to pro-BLM or negative-BLM news articles would influence verdicts and guilt ratings when compared to a control group, 2) whether this PTP effect would be different for Black versus White …

The Lingering Menace, Logan M. Burke
The Lingering Menace, Logan M. Burke
MSU Graduate Theses
This thesis applies modern approaches to better examine a largely neglected nativist publication, The Menace. This thesis also challenges the importance scholars have placed on formal associations, including prominent nativist groups such as the Klan. Instead, this thesis will focus on The Menace, a print publication that was mainstream with respect to its popularity as well as in the way it was produced. At the same time, The Menace was also similar to other nativist groups in the way it viewed race, gender, and religion.

Comparative Study Of U.S. And E.U. Experiences With Policies On Immigration Controls, Daniel Brady
MSU Graduate Theses
The year 2015 marked a colossal change in how the world views immigration. The migration crisis of Europe and the emergence of President Donald Trump continue to have lasting impacts. Major political, demographic, and social conflicts are playing out in the U.S. and Europe over migration. In the U.S., President Trump has been able to enact anti-immigration sentiment into policy. Contrary to that, in Europe, the 28 member states of the European Union have failed to come up with a clear, unifying plan to deal with the migration crisis. The consequences of migration will be harsher and less manageable in …
Territorial Behavior In Southern Red-Backed And Ozark Zigzag Salamanders: Effects Of Sex, Species, And Ownership, Colton Savage Lynn
Territorial Behavior In Southern Red-Backed And Ozark Zigzag Salamanders: Effects Of Sex, Species, And Ownership, Colton Savage Lynn
MSU Graduate Theses
Territorial disputes are common among terrestrial woodland salamanders (genus Plethodon). Males and females of both Ozark zigzag (P. angusticlavius) and southern red-backed (P. serratus) salamanders are territorial, but differing costs and benefits between sexes may influence the expression of territorial behavior. I compared the competitive and exploratory behavior of males and females of both species in laboratory experiments. Competitive behavior was assessed through staged contests between same-sex, same-sized conspecifics. There were no differences between males and females for territory owners (residents). Female intruders were more aggressive than male intruders, spending more time in and performing higher grades …
Application Of Nano-Plasmonics For Sers Bio-Detection And Photocatalysis In The Same Platform, Muhammad R. Shattique
Application Of Nano-Plasmonics For Sers Bio-Detection And Photocatalysis In The Same Platform, Muhammad R. Shattique
MSU Graduate Theses
Nano-biological systems interfacing nano-structured solid surfaces with biological compounds such as oligonucleotides or proteins are highly regarded as enabling materials for biosensing and biocatalysis applications. In particular, nanostructures of noble metals such as gold or silver, when exposed to light, exhibit a phenomenon known as surface plasmon resonance. When a proper metal nanostructure (plasmonic substrate) is exposed to light, very efficient absorption of incoming photons is possible, resulting in a buildup of localized high-energy regions, or “hot-spots”, where energetic carriers or “hot carriers” can be created. These hot-carriers can be used to catalyze desired chemical transformations in materials located nearby. …

Macrophytes And Atrazine In Ponds Of Southwest Missouri, Christine Michelle Cornish
Macrophytes And Atrazine In Ponds Of Southwest Missouri, Christine Michelle Cornish
MSU Graduate Theses
Wetlands are often the ultimate destination of agrochemicals. The increased use of these pollutants has resulted in their increased transport, via runoff and spray drift, into wetlands. Atrazine, a commonly used herbicide, has been detected in surface water, groundwater, soil, and sediment, and has shown to have adverse impacts on aquatic biota, such as fish and amphibians. Few studies have reported on the relationships between atrazine and macrophytes. I measured atrazine concentrations in surface sediments in agricultural, conservation, and golf course ponds of southwest Missouri, and investigated how those concentrations might be related to macrophyte communities, and pond environmental characteristics. …
