Description
Students Organize for Syria (SOS) is the student led initiative for Syria. With 18 registered chapters across the United States, this student organization is targeting a multidimensional cause by different means. Though it is now a national movement, it started off with one group at Arizona State University, with one student. Zana Alattar, founder and student director of SOS, tells the story of how she took an ASU organization, Save Our Syrian Freedom (SOS Freedom), to the national level as SOS. As a pre-medical student, she also combines her work in human rights with her future in healthcare. After all, health and human rights have long maintained a synergistic relationship.

Description
Dante's Divine Comedy has been around for eight centuries, and its imaginative vision of the afterlife truly resembled the ideology of 13th century. However, time has passed, and now, in 21st century, the societies have made major technological advancements that distinct themselves from the past. Consequently, with recent technology in mind, one could imagine an afterlife with robotic Minos and Cerberus, and possibly the circles of hell residing within an earth resembling death star that is controlled automatically using artificial intelligence. The symbolic representation of punishments could have been altered throughout time, and more recent criminals may be seen in the circles of hell. By identifying and correlating contemporary style of art with a classic literature such as Dante's Divine Comedy, one could better understand the essence of literature without the disconnect from current world, and appreciate the deep underlying ideology that Dante offers within his literature. Sculptures that encompass nine circles of hell and heaven would demonstrate structural aptitude and symbolic representation of what Dante would have imagined if he were to write his literature in the 21st century. Throughout the project, connection between the literature and the sculptures is observed. Some of the sculptures were meant to be abstract and some literal. Even though the medium used in each of the sculptures were different, the correlation between each sculpture unifies everything together into one theme, Dante's Divine Comedy.

Description
Higher plant Rubisco activase (Rca) is a stromal ATPase responsible for reactivating Rubisco. It is a member of the AAA+ protein superfamily and is thought to assemble into closed-ring hexamers like other AAA+ proteins belonging to the classic clade. Progress towards modeling the interaction between Rca and Rubisco has been slow due to limited structural information on Rca. Previous efforts in the lab were directed towards solving the structure of spinach short-form Rca using X-ray crystallography, given that it had notably high thermostability in the presence of ATP-γS, an ATP analog. However, due to disorder within the crystal lattice, an atomic resolution structure could not be obtained, prompting us to move to negative stain electron microscopy (EM), with our long-term goal being the use of cryo-electron microscopy (cryo-EM) for atomic resolution structure determination. Thus far, we have screened different Rca constructs in the presence of ATP-γS, both the full-length β-isoform and truncations containing only the AAA+ domain. Images collected on preparations of the full-length protein were amorphous, whereas images of the AAA+ domain showed well-defined ring-like assemblies under some conditions. Procedural adjustments, such as the use of previously frozen protein samples, rapid dilution, and minimizing thawing time were shown to improve complex assembly. The presence of Mn2+ was also found to improve hexamer formation over Mg2+. Calculated class averages of the AAA+ Rca construct in the presence of ATP-γS indicated a lack of homogeneity in the assemblies, showing both symmetric and asymmetric hexameric rings. To improve structural homogeneity, we tested buffer conditions containing either ADP alone or different ratios of ATP-γS to ADP, though results did not show a significant improvement in homogeneity. Multiple AAA+ domain preparations were evaluated. Because uniform protein assembly is a major requirement for structure solution by cryo-EM, more work needs to be done on screening biochemical conditions to optimize homogeneity.

Description
Within our current educational infrastructure, there’s a lack of substantial preventive care knowledge present among elementary schoolchildren. With education cuts occurring statewide, many schools are left impoverished and schools are incapable of implementing various programs to benefit their local communities. This endeavor aims to visit public and charter elementary schools in the Phoenix Valley to educate youth regarding easily avoidable health risks by implementing healthy eating habits and exercise. Project BandAid will immerse students ages 7-9 in hands-on activities to enhance their knowledge on hygiene, healthy eating habits, and safety. This project incorporated funding from the Woodside Community Action Grant and Barrett, the Honors College as well as the help from Alpha Epsilon Delta (AED) volunteers.

Description
The Heliobacterial Reaction Center (HbRC) is the simplest Type I Reaction Center (RC) known today. However, upon illumination it has been found to produce menaquinol, and this has led to experiments investigating the function of this reduction scheme. The goal of the experiment was to investigate the mechanisms of menaquinol production through the use of Photosystem II (PSII) herbicides that are known to inhibit the QB quinone site in Type II RCs. Seven herbicides were chosen, and out of all of them terbuthylazine showed the greatest effect on the RC in isolated membranes when Transient Absorption Spectroscopy was used. In addition, terbuthylazine decreased menaquinone reduction to menaquinol by ~72%, slightly more than the reported effect of teburtryn (68%)1. In addition, terbuthylazine significantly impacted growth of whole cells under high light more than terbutryn.

Description
The tarot is a means of communication with the world. It allows readers to interpret signs from their surroundings, gather information, and use this information to make inferences about a posed question. Its origins can be found in mid-15th century Europe as playing cards with four suits commonly used for gambling. Several hundred years later during the 18th century, it began to be used as a tool for divination; the Major Arcana, a set of 22 trump cards representing various archetypes, evolved as a supplement to a new tarot that has become associated with mysticism. The tarot’s foundation is based on archetypes that build society. It can serve as a visual lens to understand the experiences, thoughts, and actions of a person posing a question, allowing the reader to offer a solution by understanding and interpreting the specific visual language of a deck.
Hinduism is one of the oldest religions in the world and one of the most practiced today. It is full of fantastical myths and heroic legends, as well as undercurrents of feminism contrasted with misogyny and patriarchy. Hindu myths are contradictory as stories have evolved over time and have been retold with millions of differing perspectives.
In my thesis, I portrayed the 22 archetypes of the Major Arcana of the tarot through the lens of Hindu mythology as well as the broader pan-Indian culture. I include ancient stories and references to modern social issues. I visually communicated the connections between characters of Hindu mythology and the archetypes of the tarot with 22 watercolor paintings. This project was an opportunity to explore both the tarot through Hinduism, vice-versa. It allowed for the development of a deeper connection with spirituality and religion, along with a greater understanding of visual communication.

Description
In oxygenic photosynthesis, conversion of solar energy to chemical energy is catalyzed by the<br/>pigment-protein complexes Photosystem II (PSII) and Photosystem I (PSI) embedded within the<br/>thylakoid membrane of photoautotrophs. The function of these pigment-protein complexes are<br/>conserved between all photoautotrophs, however, the oligomeric structure, as well as the<br/>spectroscopic properties of the PSI complex, differ. In early evolving photoautotrophs, PSI<br/>exists in a trimeric organization, but in later evolving species this was lost and PSI exists solely<br/>as a monomer. While the reasons for a change in oligomerization are not fully understood, one<br/>of the 11 subunits within cyanobacterial PSI, PsaL, is thought to be involved in trimerization<br/>through the coordination of a calcium ion in an adjacent monomer. Recently published<br/>structures have demonstrated that PSI complexes are capable of trimerization without<br/>coordinating the calcium ion within PsaL.<br/>5 Here we explore the role the calcium ion plays in both<br/>the oligomeric and spectroscopic properties in PSI isolated from Synechocystis sp. PCC 6803.

Description
Coral reefs are diverse marine ecosystems, where reef building corals provide both the structure of the habitat as well as the primary production through their symbiotic algae, and alongside algae living on the reef itself, are the basis of the food web of the reef. In this way, coral reefs are the ocean's "forests" and are estimated to support 25% of all marine species. However, due to the large size of a coral reef, the relative inaccessibility and the reliance on in situ surveying methods, our current understanding of reefs is spatially limited. Understanding coral reefs from a more spatially complete perspective will offer insight into the ecological factors that contribute to coral reef vitality. This has become a priority in recent years due to the rapid decline of coral reefs caused by mass bleaching. Despite this urgency, being able to assess the entirety of a coral reef is physically difficult and this obstacle has not yet been overcome. However, similar difficulties have been addressed in terrestrial ecosystems by using remote sensing methods, which apply hyperspectral imaging to assess large areas of primary producers at high spatial resolutions. Adapting this method of remote spectral sensing to assess coral reefs has been suggested, but in order to quantify primary production via hyper spectral imaging, light-use efficiencies (LUEs) of coral reef communities need to be known. LUEs are estimations of the rate of carbon fixation compared to incident absorbed light. Here, I experimentally determine LUEs and report on several parameters related to LUE, namely net productivity, respiration, and light absorbance for the main primary producers in coral reefs surrounding Bermuda, which consist of algae and coral communities. The derived LUE values fall within typical ranges for LUEs of terrestrial ecosystems, with LUE values for coral averaging 0.022 ± 0.002 mol O2 mol photons-1 day-1 at a water flow rate of 17.5 ± 2 cm s^(-1) and 0.049 ± 0.011 mol O2 mol photons-1 day-1 at a flow rate of 32 ± 4 cm s^(-1) LUE values for algae averaged 0.0335 ± 0.0048 mol O2 mol photons-1 day-1 at a flow rate of 17.5 ± 2 cm s^(-1). These values allow insight into coral reef productivity and opens the door for future remote sensing applications.
