Capsaicin and dihydrocapsaicin account for 90% of capsaicinoids when it comes to the pungency of peppers. Capsaicin stability was investigated through a cooking and storage parameter where three different tests were done; cooking duration, cooking temperature, and storage stability. The concentration of capsaicinoids was quantified through gas chromatography-mass spectrometry where those values were then used to determine the total Scoville heat units (SHU). Furthermore, half-life was determined by finding the decay rate during cooking and storage. Results showed that there was an increase in degradation of capsaicinoids concentration when peppers were cooked for a long period of time. Degradation rate increases with increasing temperatures as would be expected by the Arrhenius equation. Hence, if a maximum pungency is wanted, it is best to cook the least time as possible or add the peppers towards the end of the culinary technique. This would help by cooking the peppers for a short period of time while not being exposed to the high temperature long enough before significant degradation occurs. Lastly, the storage stability results interpreted that a maximum potency of the peppers can be retained in a freezer or refrigerator opposed to an open room temperature environment or exposure from the sun. Furthermore, the stability of peppers has a long shelf life with even that the worse storage condition's half-life value was 113.5 months (9.5 years). Thus, peppers do not need to be bought frequently because its potency will last for several years.

Description
This paper is intended to identify a correlation between the winning percentage of sports teams in the four major professional sports leagues in the United States and the GDP per capita of their respective cities. We initially compiled fifteen years of franchise performance along with economic data from the Federal Reserve Bank of St. Louis to analyze this relationship. After converting the data into a language recognized by Stata, the regression tool we used, we ran multiple regressions to find relevant correlations based off of our inputs. This paper will show the value of the economic impact of strong or weak performance throughout various economic cycles through data analysis and conclusions drawn from the results of the regression analysis.

Description
The purpose of our research was to develop recommendations and/or strategies for Company A's data center group in the context of the server CPU chip industry. We used data collected from the International Data Corporation (IDC) that was provided by our team coaches, and data that is accessible on the internet. As the server CPU industry expands and transitions to cloud computing, Company A's Data Center Group will need to expand their server CPU chip product mix to meet new demands of the cloud industry and to maintain high market share. Company A boasts leading performance with their x86 server chips and 95% market segment share. The cloud industry is dominated by seven companies Company A calls "The Super 7." These seven companies include: Amazon, Google, Microsoft, Facebook, Alibaba, Tencent, and Baidu. In the long run, the growing market share of the Super 7 could give them substantial buying power over Company A, which could lead to discounts and margin compression for Company A's main growth engine. Additionally, in the long-run, the substantial growth of the Super 7 could fuel the development of their own design teams and work towards making their own server chips internally, which would be detrimental to Company A's data center revenue. We first researched the server industry and key terminology relevant to our project. We narrowed our scope by focusing most on the cloud computing aspect of the server industry. We then researched what Company A has already been doing in the context of cloud computing and what they are currently doing to address the problem. Next, using our market analysis, we identified key areas we think Company A's data center group should focus on. Using the information available to us, we developed our strategies and recommendations that we think will help Company A's Data Center Group position themselves well in an extremely fast growing cloud computing industry.

Description
Vitamin D, Klotho, and FOXO3 have all been linked to have anti-aging and anti-cancerous effects as separate pathways. Specifically, mice with knockout Klotho in their genes have displayed signs of premature aging, humans who are vitamin D deficient have been shown to develop cardiovascular disease and cognitive impairments, and those who have displayed overexpression of FOXO3 have shown to have a longer lifespan. Here we took each pathway and attempted to formulate a feedback mechanism loop linking all three separate pathways. We propose that vitamin D levels modulate klotho activity, including the expression of the s-klotho and m-klotho isoforms. Moreover, the anti-oxidation transcription factor FOXO3 is also thought to participate in crosstalk with VDR signaling. Through the connection between 1,25D and Klotho, we probed at their interactions with FOXO3 signaling in kidney and colon cells, and proposed that vitamin D and klotho may reduce oxidative stress and suppress the onset of epithelial cancers through it effects on FOXO3. Results showed a strong support for the cooperation between FOXO3 and 1,25D to stimulate both superoxide dismutase (a FOXO3 response element) and XDR3/ROC (vitamin D response elements). This cooperation was mostly seen in embryonic kidney cells (HEK293) and not in the colon cancer cells (HCT116), which has led to the conclusion that vitamin D and FOXO3 cooperation mainly occurs in kidney tissue and/or in tissue that is not yet been overtaken by cancer. Differences in the Klotho isoforms were seen when measuring FOXO3 and vitamin D activity, but experiments manipulating other components will need to be conducted to further understand the function of Klotho in maintaining reactive oxygenated species levels.

The inspiration behind my thesis comes from my third grade teacher who completed numerous Ironman races. In third grade, I decided that one day I would complete an Ironman too. Thus, for my thesis I studied the Ironman race series and analyzed the power of the Ironman brand. In addition to researching Ironman, I experienced the essence of Ironman first hand by completing an Ironman 70.3 race. My thesis documents the history of Ironman and how one small race in Hawaii has grown to over 242 races held worldwide. It describes the types of people who complete in Ironman races and the demographics of competitors. Through my research, I concluded that the brand power of Ironman is what makes the race series so strong. I attributed the following five categories to the success of Ironman: Quality Differentiation, Brand Development, Exclusivity, Media Relations, and Partnerships and Products. Additionally, I researched competing triathlon race series and concluded that they just cannot compete with the Ironman brand. Participants even state that they would not propel themselves across 140.6 total miles of water, pavement, and trail if they cannot attach "Ironman" to their name. Therefore, Ironman has a strong hold on the triathlon industry and continues to grow at a rate of 20% each year. In order to fully experience the quality, organization, and inspiration of Ironman, I registered for an Ironman 70.3 race in Oceanside, California. For the past year, I have experienced the struggles and triumphs of athletes training for an Ironman race. I have sacrificed things such as sleep, free time, and a social life in order to fully experience what athletes go through to train for an Ironman event.

Description
Partial differential equation (PDE) models are widely used for modeling processes in the physical sciences, economics, and sociology, but are otherwise new to the realm of social media. They allow researchers to construct a single spatiotemporal mathematical model to predict, in the case of this study, the level of information saturation at particular points in space at specific times. Utilizing data from the popular social network Twitter, this study presents a preliminary work looking into the effects of aggregating spatial data on such a PDE model. In other literature, the source of analytical and statistical bias that results from arbitrary spatial aggregation is known as the modifiable areal unit problem (MAUP). We use a previously-studied dataset from the 2011 Egyptian revolution for simulation, and group data points using several distance metrics based on geographical location and geo-cultural similarity. This paper will attempt to show that a PDE model, necessarily dependent upon aggregating data, is subject to significant bias when said data are arbitrarily organized and grouped for simulation. We look primarily into the zoning problem, which amounts to maintaining a fixed number of regions located in different areas across the globe, but make note of the scale problem, an inherent issue in PDE modeling that results from aggregating data points into increasingly larger regions. From looking at specific values from each simulation, this study shows that such a model is not free from the MAUP and that consideration of how data are aggregated needs to be made for future studies. In addition, it also suggests that geo-political and geo-cultural spatial metrics generate better diffusive patterns for tweet propagation than do simple geographical proximity metrics.

Description
Desert ecosystems are one of the fastest urbanizing areas on the planet. This rapid shift has the potential to alter the abundances and species richness of herbivore and plant communities. Herbivores, for example, are expected to be more abundant in urban desert remnant parks located within cities due to anthropogenic activities that concentrate food resources and reduce native predator populations. Despite this assumption, previous research conducted around Phoenix has shown that top-down herbivory led to equally reduced plant biomass. It is unclear if this insignificant difference in herbivory at rural and urban sites is due to unaltered desert herbivore populations or altered activity levels that counteract abundance differences. Vertebrate herbivore populations were surveyed at four sites inside and four sites outside of the core of Phoenix during fall 2014 and spring 2015 in order to determine whether abundances and richness differ significantly between urban and rural sites. In order to survey species composition and abundance at these sites, 100 Sherman traps and 8 larger wire traps that are designed to attract and capture small vertebrates such as mice, rats, and squirrels, were set at each site for two consecutive trap nights. Results suggest that the commonly assumed effect of urbanization on herbivore abundances does not apply to small rodent herbivore populations in a desert city, as overall small rodent abundances were statistically similar regardless of location. Though a significant difference was not found for species richness, a significant difference between small rodent genera richness at these sites was observed.

Description
Limited researches have studied on the dissonance of the representations of a destination by using difference induced agents such as government, trade media tourism articles, and visual representations. This study examines the United Kingdom's image, and determines whether the dissonance exist pre- and post- referendum in the internal imagery of the United Kingdom and imagery portrayed aboard. Leading newspapers from the United States, United Kingdom, and Europe are analyzed to determine the predominant themes. Semi-structured interviews are conducted with the U.S. tour operators and Arizona's travel agents. Tour brochures and user-generated content on TripAdvisor are analyzed to study tourists' responses to Brexit. Skift is analyzed to project future growth in tourism industry. Results show that the leadings newspapers projects similar concerns negatively and positively pre- and post- referendum. Uncertainty in policy changes leads to other themes that are identified such as investment, employment, trade, independence, market growth, etc. It projects the international trade, domestic market growth and global market growth will be significantly impact by Brexit due to higher tariff and regulations on migrants in the United Kingdom. In contrast, travel brochures are marketing UK from heritage, historical attractions, and special events, but they do not reflect the influence of Brexit on how tour operators market UK pre- and post- referendum. Further data is conducted on the semi-structured interviews with travel agents across Arizona, but travel agents responded with Brexit has no influences on US tourists. Additional content analysis on VisitBritain/VisitEngland shows the growth in tourism industry by an increasing provided data collection on tourism performance that reflect there is an increasing departure rate of US tourists in UK after the referendum. User-generated content on TripAdvisor and Skift align with the identified themes in leading newspapers from US, UK, and Europe such as uncertainty in policy change. The present study further outlines preferable method to advance future studies on the destination image of U.K. during and after the Brexit.

Description
For this thesis, the authors would like to create a hypothetical Private Equity Real Estate Investment firm that focuses on creating value for partners by taking an opportunistic approach to acquiring under-performing urban multi-family properties with large upside potential for investing. The project will focus on both the market analysis and financial modeling associated with investment strategy and transactions. There is a substantial amount of complexity within commercial real estate and this thesis seeks to offer an accurate and comprehensive documentary of the process, while simplifying it for everyday readers. Additionally, there are a significant amount of risk factors associated with investment decisions, so the best practices from the industry documented in this manuscript are valuable tools for successful investing in the future. To gain the most profound and reliable industry knowledge, the authors leveraged the experience of dozens of industry professionals through research and personal interviews. Through careful analysis, the authors were able to ascertain the current economic position in the real estate cycle and to create a plan for future investing. Additionally, they were able to identify and evaluate a specific asset for purchase. As a result, the authors found that multifamily properties are a sound investment for the next two years and that the company should slowly start to shift directions to office and retail in 2018.
