Description
Extensive literature exists examining the maximum mitigation potential of
biochar. This research has found biochar to hold massive potential as a means of stabilizing current levels of atmospheric carbon. Furthermore, the research and resources to massively expand biochar production exist, yet one could easily argue the industry is not expanding quickly enough given its known potential benefits. This paper serves to address this lack of growth, and identified a lack of formalized networks for knowledge and innovation exchanges amongst biochar production firms as a leading obstacle to quick expansion. I focus on two particular biochar production firms operating in vastly different contexts and analyze both through a conceptual framework known as “knowledge networks”. In depth literature on the topic of knowledge networks highlight the dynamics of exchange, including the obstacles in establishing such a network. I applied the findings from a multitude of case studies centered around knowledge networks to biochar production, asserting that exchange networks centered around reciprocity would serve as a catalyst to the growth of the biochar industry. I also assert that public research institutions such as Arizona State University would play a critical role in such a network, as they would serve as a mutual party connecting two private entities. Private biochar production firms around the world would be exposed to new knowledge and information that would serve to maximize the energy value of their product while reducing the environmental externalities associated with their process.

Description
Perfection’s Reflection: Influencers on Bodybuilder Behavior is an honors thesis project that provides insight on the impact of influencers and may be a value to those who wish to be influential to competitive bodybuilders. Six current and former competitive bodybuilders explained the impact of influencers in seven key themes: 1.) Body dissatisfaction, 2.) Inspiration, 3.) Imitation, 4.) Motivation, 5.) Skepticism and distrust, 6.) Information, and 7.) Avoidance. These seven key themes were identified throughout three stages of the bodybuilders’ journeys, “The Beginning,” during their early childhood to high school years, “The Middle,” the start of their bodybuilding careers, and “The End,” the present day. It is concluded that influencers may impact competitive bodybuilders differently based on the stage of their journeys and to be influential, one should provide the ideal impact based on bodybuilders’ stage of their journeys.

Description
When limited for iron, Escherichia coli secretes a siderophore, enterobactin, to solubilize and intake extracellular Fe3+ by a TonB-dependent high-affinity pathway. Consequently, E. coli tonB mutants grow poorly on a medium limited for iron. Upon longer incubation, however, faster growing colonies emerge and overcome this growth defect. The work presented in this paper reports and characterizes these faster growing colonies (revertants) in an attempt to dissect the mechanism by which they overcome the TonB deficiency. Genomic analysis revealed mutations in yejM, a putative inner-to-outer membrane cardiolipin transporter, which are responsible for the faster growth phenotype in a tonB mutant background. Further characterization of the revertants revealed that they display hypersensitivity to vancomycin, a large antibiotic that is normally precluded from entering E. coli cells, and leaked periplasmic proteins into the culture supernatant, indicating a compromised outer membrane permeability barrier. All phenotypes were reversed by supplying the wild type copy of yejM on a plasmid, suggesting that yejM mutations are solely responsible for the observed phenotypes. In the absence of wild type tonB, however, the deletion of all known of cardiolipin synthase genes (clsABC) did not produce the phenotype similar to mutations in the yejM gene, suggesting the absence of cardiolipin from the outer membrane per se is not responsible for the increased outer membrane permeability. These data show that a defect in lipid biogenesis and transport can compromise outer membrane permeability barrier to allow siderophore intake and that YejM may have additional roles other than transporting cardiolipin.

Description
Youth voters in the US have had a steadily declining turnout since the right to vote was expanded to include 18-20 year old citizens in 1971. The decline appears to be related to both internal reasons and external reasons. Internal reasons include apathy about the political process, while external reasons can include voter suppression tactics such as voter identification laws and laws preventing felons from voting. For those that currently participate in the political process, social media appears to play a big part in youth spreading their political opinions. The recent expansion of early voting has resulted in more young people voting by early voting, showing that making voting more accessible allows young people to exercise their political voice through voting. Despite internal and external obstacles young voters face while voting, new voting methods have the potential to expand the turnout of youth voters.

Description
2,2’ bipyridine (Bpy) can form metal complexes with divalent metals in the form of [M(Bpy-ala)¬3]+2 where M is any divalent metal. These [M(Bpy-ala)¬3]+2 complexes can have very interesting photochemical and redox potentials that can be useful in more complex systems. The use of (2,2′-bipyridin-5yl)alanine (Bpy-ala) as a Noncanonical Amino Acid (NCAA) has allowed Bpy to be incorporated into an amino acid sequence which can now function in a protein scaffold. Previous studies have utilized that power of Bpy-ala to design a protein that can assemble a homotrimeric protein complex in the presence of a divalent metal. However, the issue with this design was that when the homotrimer was formed and the divalent was removed, the protein complex would not dissemble indicating that it was not metal dependent. Point mutations were made to disrupt the protein-protein interactions to favor disassembly in the absence of a divalent metal. Successfully, a mutation was made that allowed the designed protein to be metal dependent for self-assembly. Nevertheless, an issue with this design is that it poorly incorporated ruthenium(II) into the tris Bpy complex forming [Ru(Bpy-ala)¬3]+2, which was one of the main goals of the original design. This thesis sets out to form TRI 05 I13S M6I which should uphold the same metal-dependence as its predecessor and should combine ruthenium (II) into the protein complex forming [Ru(Bpy-ala)¬3]+2. The thesis shows the success of formation and expression of TRI 05 I13S M6I in Escherichia coli cells. This thesis also reports several purification steps and procedures to not only purify TRI 05 I13S M6I but also removing both the His-tag sequence and Fe(II) from the protein. The thesis also shows that TRI 05 I13S M6I does not behave like its predecessor in that it is not metal dependent for self-assembly. While this may be true, this paper also reports the incorporation of ruthenium (II) in the protein structure. Though this may be the first time that ruthenium (II) has been recorded to be in the TRI 05 protein complex with a significant signal, it is still nowhere near the optimal fluorescence that small molecule Bpy can achieve by itself. The thesis reports potential conditions and a plan of attack that should drive this project forward into achieving an optimal signal of the [Ru(Bpy-ala)¬3]+2 complex in a TRI 05 protein scaffold.

Description
With brick-and-mortar retail actively under threat from a growing e-commerce market, companies are being challenged to re-evaluate the way they engage with their customers in the physical realm. Companies are under pressure to give consumers a reason to make a trip to their stores over succumbing to the convenience of sitting at home in their pajamas and shopping online. Because of the rapid development of e-commerce, there is a growing necessity for retailers to prove their worth by means of marketing the in-store experience as superior to that of what online could offer. Brands are navigating the grey area between the digital and physical realms in order to successfully fulfill the needs of the modern consumer through viewing these different entities as touchpoints in the overall consumer experience.
This study explores the connection between the interior design of retail spaces and consumer behavior in the direct-to-consumer environment. The research explores the relationships between consumer behavior, intangible brand identity, and the physical (brick-and-mortar) retail environment and explores interior design’s role in the development of a new form of retail found in brands whose presence began online and later entered the physical realm. Through analyzing store aesthetics, consumer preferences, and purchasing behavior, this research provides insight into what matters to consumers in a direct-to-consumer retail environment and how designers at the forefront of this movement are adapting, and ultimately draws conclusions about how companies can utilize interior design and store aesthetics as part of the consumer journey to maximize the impact of their brand experiences.

Description
In June of 2016, the United Kingdom held a referendum for its citizens to decide whether to remain a part of the European Union or take their leave. The vote was close but ultimately the U.K. decided to leave, triggering the two-year process of negotiations that would shape the U.K.’s departure (Brexit). The question of what will become of the border between Northern Ireland and the Republic of Ireland is heavy with implications for the national identity of people living on either side of the border, and this makes it one of the more pressing concerns in Brexit discourse. This research analyzes how national identity is used as a rhetorical tactic in media to influence and persuade readers to vote in accordance with the author’s political goals. It does so by evaluating how borders shape national identity and analyzing newspaper articles from the two highest circulating Northern Irish daily newspapers (The Irish News and the Belfast Telegraph) during the week leading up to the June 23rd, 2016 referendum. In analyzing news articles relating to the Irish border issue of Brexit from The Irish News and the Belfast Telegraph during the time frame of June 16th-23rd, 2016, four analytical categories of how identity-related rhetoric was used were discovered: fear, self-interest, Irish Nationalism, and a negative association of the past. Further, it was hypothesized and confirmed the political leanings of the papers influenced which type of rhetorical tactic was used. In the broad realm of Brexit and media related discussion, this research could help strengthen understanding of how traditional media uses national identity to persuade readers to and influence voting behavior in the midst of such a divisive referendum.

Description
The field of bioprocess engineering has become an increasingly popular route to produce chemicals and fuels in a sustainable fashion. Bioprocessing is an interdisciplinary field that joins chemical engineering, metabolic engineering, and synthetic biology to tackle problems that will arise from the ongoing use of products derived from non-renewable resources. This study will overlook two effective tools that are widely used in the bioprocessing field. The first tool that was studied was strain optimization for biochemical production. This involves genetic manipulation of microbial hosts to create strains that are more efficient at producing the desired products. The second tool that was studied was adaptive laboratory evolution which is used to enhance overall cellular fitness. Enhancing the overall fitness and efficiency of these microbial production factories, allows for innovation and growth in the biochemical industry. Creating sustainable and renewable solutions for both specialty and commodity chemicals.
Strain optimization was specifically studied by enhancing inorganic carbon uptake in synechococcus sp. 7002. It is desired to have both high flux and high affinity transport for the rapid and efficient uptake of HCO3- for enhanced cell growth. The results found that the regulatory gene for carbon transporters in synechococcus genome was successfully deleted. Increasing the toxicity limits of 2-Phenylethanol was done by using adaptive laboratory evolution (ALE). ALE is a widely used practice in biotechnology studies to gain insights on mechanisms of molecular evolution and to better define the functionality of microbial cell factories. It was found that after growing E. coli BW25113 under selective conditions the genome evolved for a higher fitness medium with an increased concentration of 2-Phenylethanol. Overall, two key tools used in bioprocess engineering were successful studied to gain a better insight on the future of biochemical production industry.

Since e-cigarettes were put on the market in 2007, the use of them has increased rapidly especially among young adults and adolescents. The purpose of this thesis was to identify young individuals’ harm perceptions of using e-cigarettes as compared to the harm perceptions of using carcinogens, and to compare the physiological effects of using e-cigarettes with those same carcinogens. Research was conducted by searching the Arizona State University Library website for articles that pertained to perceptions and physiological effects of e-cigarettes, conventional cigarettes, marijuana, and methamphetamine. Overall, young individuals have extremely low harm perceptions of using e-cigarettes, as compared to the other carcinogens. They perceived cigarettes to be the most dangerous and had the most knowledge on the subject, followed by methamphetamine, marijuana, and e-cigarettes with very little knowledge on the latter subjects. Many of the physiological effects of using e-cigarettes found in the research were shared with conventional cigarettes, marijuana, and methamphetamine. Specifically, using e-cigarettes results in negative physiological effects such as increased airway resistance, increased airway and lung tissue inflammation, increased bronchitic symptoms, increased mucin production, distal airspace enlargement, and increased cytokine and protease expression which are linked to COPD in chronic cigarette smokers. Other effects associated with decreased lung and respiratory function were shared with the chronic use of conventional cigarettes, marijuana, or methamphetamine. These findings can be used to inform young individuals of the harms that e-cigarettes may cause. More research needs to be conducted on the topic to identify the full range of physiological effects that using e-cigarettes may have on the body.

Description
Piloerection (known as goosebumps) is mediated by activation of alpha-adrenergic receptors within the sympathetic branch of the autonomic nervous system. The study of piloerection is important in multiple fields, from emotion studies to nervous system pathology. This makes piloerection particularly relevant to emotions research. Despite wide-ranging applications, current methods for measuring piloerection are laborious and qualitative. The goal of this study is to build a wearable piloerection sensor through the use of straight-line lasers and photoresistors. The study analyzed methods of detecting and measuring goosebumps, and applied the method of laser scattering as a detection method. This device was designed and tested against a population of seven Arizona State University students. Goosebumps were elicited through conditions of cold, and video clips meant to elicit emotions of awe and sadness. Piloerection was then quantified through two controls of self-identification and camera recording, as well as the new detection method. These were then compared together, and it was found that subjective methods of determining goosebumps did not correlate well with objective measurements, but that the two objective measurements correlated well with one another. This shows that the technique of laser scattering can be used to detect goosebumps and further developments on this new detection method will be made. Moreover, the presence of uncorrelated subjective measurements further shows the need for an objective measurement of piloerection, while also bringing into question other factors that may be confused with the feeling of piloerection, such as chills or shivers. This study further reaffirmed previous studies showing a positive correlation between intense emotions.
