Description
Emission Spectroscopy is a powerful tool for the identification of mineralogical samples and has been used for decades in labs to study the geology of Earth and Mars. However, the instruments needed to make these measurements are large, expensive and sensitive pieces of equipment that are too cumbersome to use in the field. There are some commercial products that attempt to work in the field, however they perform this task poorly, often resulting in limited applications, poor performance or not being truly portable. My thesis utilizes the TES family of planetary instruments as a source of inspiration for creating a truly portable Fourier Transform InfraRed spectrometer. From this initial design phase, it appears that it is possible to build an instrument with vastly improved capabilities over the current systems on the market. This roughly 12 inch by 7 inch by 8 inch device with a 3-inch diameter telescope is capable of achieving a SNR of over 1000 during a 5 minute scan of a sample allowing for 5 sigma (99.99994% Confidence) identification of 1% spectral features from 5 um to >60 um making this instrument a one of a kind device with high application potential, not only for field geologist but for the future of manned exploration of space. Currently an accurate measurement of costs is not available, however with more development and optimization a total cost of around $50K is feasible while still maintaining the same performance characteristics. If the costs can fall within an acceptable range, this device will not only be technically impressible but viable from a financial standpoint as well.

Description
In post-industrialized societies, increased consumption of fat-rich diets has been correlated to increasing rates of metabolic disorders, such as Type II Diabetes, which is further linked to insulin resistance. Due to this modern epidemic, it has become exceedingly important to learn more about these disorders with the ultimate goal of developing more effective treatments. With an overall focus on insulin resistance, the main purposes of this study were to (1) differentiate between two types of insulin resistance and their corresponding measurements and to (2) demonstrate metabolic changes that occur in response to overconsumption of a calorically dense diet. This was accomplished over a 23-week timespan by applying statistical analysis to periodically measured fasting insulin and blood glucose levels in rats fed either a high fat diet or low fat (chow) diet. Body weights were also recorded. The results of this study showed that rats fed a high fat diet experienced fasting hyperinsulinemia, hyperglycemia, and insulin resistance compared to rats fed a chow diet, and that the homeostatic model assessment (HOMA) scale and insulin-stimulated glucose disposal (ISGD) measure different types of insulin resistance. This study was unique in the fact that hepatic insulin resistance and peripheral insulin resistance were differentiated in the same rat.

For typological and historical reasons, the category of prepositions in Modern Chinese
has been long debated in terms of its distribution, its classification, and even its very existence. This paper defends the existence of a prepositional category in Chinese as well as offers means to identify the category and distinguish prepositions from verbs by analyzing their distribution and syntactic capabilities. The research for this paper is based on existing literature on Chinese prepositions, Chinese syntax, and linguistic theories as well as on corpus analysis.

Description
Common treatments for substance addiction in the United States (U.S) are the twelve-step programs of Alcoholics Anonymous (AA) and Narcotics Anonymous (NA). However, there is a lack of evidence indicating the effectiveness of AA and NA as substance addiction treatment methods. The U.S. is currently grappling with one of its worst-ever alcohol and drug crises, illustrating that now more than ever it is necessary to examine alternative treatment methods for substance addiction to successfully treat this type of addiction. Thus, Buddhism can be seen as both a complement to and alternative for AA and NA treatment programs for treating substance addiction. The Buddhist teachings and practices of the Four Noble Truths, The Eightfold Path, mindfulness, and meditation can be used to treat substance addiction. Although only recently utilized in the U.S. to treat substance addiction, Buddhist teachings and practices offer a nontheistic approach to recovery which research has shown to be successful in treating substance addiction in countries with established Buddhist cultures. By determining what treatment method is most successful in treating this type of addiction, the U.S. will be able to effectively reduce substance addiction rates -- which is crucial to protect the health, safety, and quality of life for all.

Residential Choice’s Impact on Sustainable Transportation Options: A Study in the Phoenix Metro Area
Description
This study adds to the literature about residential choice and sustainable transportation. Through the interviews and the personal stories gathered, there was diversity shown in the residential location choice process. We also noticed that “commute” means different things to different households, and that many people did not consider their commute to work to be a primary factor determining their final home location. Moreover, many people were willing to increase their commute time, or trade access to desirable amenities for a longer commute. Commuting time to work was one example of the tradeoffs that homeowners make when choosing a home, but there were also others such as architectural type and access to neighborhood amenities. Lastly, time constraints proved to be a very significant factor in the home buying process. Several of our households had such strict time constraints that limited their search to a point of excluding whole areas. Overall, our study sheds light on transportation’s role in residential choice and underscores the complexity of the location choice process.

Description
Carbon allotropes are the basis for many exciting advancements in technology. While sp² and sp³ hybridizations are well understood, the sp¹ hybridized carbon has been elusive. However, with recent advances made using a pulsed laser ablation in liquid technique, sp¹ hybridized carbon allotropes have been created. The fabricated carbon chain is composed of sp¹ and sp³ hybridized bonds, but it also incorporates nanoparticles such as gold or possibly silver to stabilize the chain. The polyyne generated in this process is called pseudocarbyne due to its striking resemblance to the theoretical carbyne. The formation of these carbon chains is yet to be fully understood, but significant progress has been made in determining the temperature of the plasma in which the pseudocarbyne is formed. When a 532 nm pulsed laser with a pulsed energy of 250 mJ and pulse length of 10ns is used to ablate a gold target, a peak temperature of 13400 K is measured. When measured using Laser-Induced Breakdown spectroscopy (LIBS) the average temperature of the neutral carbon plasma over one second was 4590±172 K. This temperature strongly suggests that the current theoretical model used to describe the temperature at which pseudocarbyne generates is accurate.

Description
This thesis seeks to examine shortcomings in space law by focusing on two interconnected aspects: privatization and space debris. The aspects of privatization and space debris will be examined under the context of the Outer Space Treaty (OST) and other relevant legal instruments. Privatization and space debris are two current challenges that the OST fails to regulate efficiently. While the OST was being drafted, the international community did not foresee problems such as privatization and space debris. This is significant because we are witnessing an increase in privatization of space activities and corporations as well as a massive accumulation of dangerous space debris. While the OST grants states the power to regulate private space companies and the accretion of space debris, national laws rarely align with the OST, leading to the abuse of international space laws. We will make recommendations at the end of the thesis in an effort to revise the use of soft language in the OST to attune national laws with international laws as well as address the growing ambiguity surrounding privatization and space debris.

Description
In this study, we demonstrate the effectiveness of a cancer type specific FrAmeShifT (FAST) vaccine. A murine breast cancer (mBC) FAST vaccine and a murine pancreatic cancer (mPC) FAST vaccine were tested in the 4T1 breast cancer syngeneic mouse model. The mBC FAST vaccine, both with and without check point inhibitors (CPI), significantly slowed tumor growth, reduced pulmonary metastasis and increased the cell-mediated immune response. In terms of tumor volumes, the mPC FAST vaccine was comparable to the untreated controls. However, a significant difference in tumor volume did emerge when the mPC vaccine was used with CPI. The collective data indicated that the immune checkpoint blockade therapy was only beneficial with suboptimal neoantigens. More importantly, the FAST vaccine, though requiring notably less resources, performed similarly to the personalized version of the frameshift breast cancer vaccine in the same mouse model. Furthermore, because the frameshift peptide (FSP) array provided a strong rationale for a focused vaccine, the FAST vaccine can theoretically be expanded and translated to any human cancer type. Overall, the FAST vaccine is a promising treatment that would provide the most benefit to patients while eliminating most of the challenges associated with current personal cancer vaccines.

Description
The North American Free Trade Agreement was passed by the U.S. Congress in November 1993. The United States had decided that a regional trade approach would be more beneficial than bilateral trade with its neighbors. This move accepted Mexico as an equal economic partner with the United States and Canada despite their economic deficiencies. The NAFTA agreement came into effect on January 1, 1994. Canada, Mexico, and the United States agreed to eliminate tariffs on roughly ninety-nine percent of internationally traded goods by the end of 2004. The agreement was also significant because the three nations took a big step in further liberalizing Foreign Direct Investment policies. NAFTA resulted in what is today a $19 trillion regional market with over 470 million consumers. The U.S. Chamber of Commerce estimates that six million U.S. jobs depend on trade with Mexico and another eight million jobs depend on trade with Canada. As seen, economic interests clearly dominated the NAFTA debate on all fronts. There still were other domestic political interests that further pushed the United States to seek regional integration with Canada and Mexico. Drugs, energy, pollution, and the threat of American jobs as a result of Mexico’s low wages were all major issues considered in the United States at the time. The issues noted above can be closely linked to the United States’ national security interests. Policy-makers and treaty negotiators constantly connected the passage of this agreement to the long-term interests of the United States. For NAFTA to have a chance in the first place, all operational concerns had to have been resolved first. The governing structure for management of the activities that fall under NAFTA’s umbrella was a huge prerequisite. Additionally, separate side agreements with Canada and Mexico had to be negotiated so that the they would offset any future problems NAFTA might create for the United States. Although a challenge, it all came together perfectly and the passage was successfully implemented. Taking everything into consideration, the United States should stray way from its’ isolationist ways and pursue a regional agreement like NAFTA for the betterment of all North Americans.
