As the world’s population exponentially grows, more food production is required. This increasing food production currently has led to the un-sustainable production of chemical fertilizers and resultant overuse. A more sustainable option to enhance food production could be the use of fertilizer derived from food waste. To address this, we investigated the possibility of utilizing a fertilizer derived from food waste to grow hydroponic vegetables. Arugula (Eruca sativa) ‘Slow Bolt’ and lettuce (Lactuca sativa) ‘Cherokee’ and ‘Rex’ were cultivated using indoor deep-flow hydroponic systems at 23 ºC under a photosynthetic photon flux density of 170 µmol∙m−2∙s−1 with an 18-hour photoperiod. Plant nutrient solutions were provided by food waste fertilizer or commercial 15:5:20 NPK fertilizer at the identical electrical conductivity (EC) of 2.3 mS·cm–1. At the EC of 2.3 mS·cm–1, chemical fertilizer contained 150 ppm N, 50 ppm P, and 200 ppm K, while food waste fertilizer had 60 ppm N, 26 ppm P, and 119 ppm K. Four weeks after the nutrient treatments were implemented, compared to plants grown with chemical fertilizer, lettuce ‘Rex’ grown with food waste fertilizer had four less leaves, 27.1% shorter leaves, 68.2% and 23.1% less shoot and root fresh weight, respectively. Lettuce ‘Cherokee’ and arugula grown with food waste fertilizer followed a similar trend with fresh shoot weights that were 80.1% and 95.6% less compared to the chemical fertilizer, respectively. In general, the magnitude of reduction in the plant growth was greatest in arugula. These results suggest that both fertilizers were able to successfully grow lettuce and arugula, although the reduced plant growth with the food waste fertilizer in our study is likely from a lower concentration of nutrients when we considered EC as an indicator of nutrient concentration equivalency of the two fertilizer types.

Description
In a COVID-19 world, student engagement has suffered drastically as organizations and universities shifted to an online format. Yet, there is still an opportunity and a space for digital content creation to bridge the gap in a virtual and hybrid university lifestyle. This project looks at how student groups can still engage students at ASU Tempe through digital content creation and which tools to use to enter the space.

Description
Dielectrophoresis is a separations strategy that has the potential to separate small amounts of different proteins from each other. The forces at play in the channel used for dielectrophoresis are electroosmotic flow (EOF), electrophoresis (EP), and dielectrophoresis (DEP). EOF is the force exerted on liquid from an applied potential (1). EP is the force exerted on charged particles in a uniform electric field (2). DEP is the force exerted on particles (charged and uncharged) in a non-uniform electric field (3). This experiment was focused on the testing of a new microfluidic device to see if it could improve the focusing of proteins in dielectrophoresis. It was predicted that the addition of a salt bridge would improve focusing by preventing the ions created by the electrolysis of water around the electrodes from interacting with the proteins and causing aggregation, among other problems. Control trials using the old device showed that electrolysis was likely occurring and was the causal agent for poor outcomes. After applying the electric potential for some time a pH front traveled through the channel causing aggregation of proteins and the current in the channel decreased rapidly, even while the voltage was held constant. The resistance in the channels of the control trials also slightly decreased over time, until the pH shift occurred, at which time it increased rapidly. Experimental trials with a new device that included salt bridges eliminated this pH front and had a roughly linear increase of current in the channel with the voltage applied. This device can now be used in future research with protein dielectrophoresis, including in the potential differentiation of different proteins. References: 1) Electroosmosis.

Description
In the United States, more than 22 million people are estimated to be affected by the chronic illness, asthma (American Lung Association [ALA], 2014). Of those 22 million, approximately 7.1 million are children (ALA, 2014). An important factor in trying to curb the frequency of asthma attacks is education. Particular elements of asthma education include symptom recognition, self-management skills, correct administration, and understanding how medications are used to control asthma. A review of the literature shows that multimedia education holds some promise in increasing asthma-knowledge retention. This creative project involved the creation of an asthma-education video with a concomitant asthma-education comic book. Of the two creations, the asthma-education video was used in a former Doctorate of Nursing Practice (DNP) student’s study to supplement a session at a clinic with an asthma educator. The tools included in the study, the Asthma Medication Use Questionnaire (Moya, 2014) and the Asthma Control TestTM (ACTTM; QualityMetric Incorporated, 2002), were completed by the participants prior to and after the implementation of the session that incorporated the video. The results suggested that the video had an effect on asthma control as measured by the ACTTM (QualityMetric Incorporated, 2002), but not on daily preventative asthma inhaler usage as measured by the Asthma Medication Use Questionnaire (Moya, 2014). The comic book has not been evaluated yet. Both multimedia education tools—the comic book and the video—were created as a requirement for the Barrett thesis.

Description
The aim of this project was to conduct an investigation of the cosmetic industry, particularly the field encompassing Botox and dermal fillers. The research helped to identify the various types of fillers used in the market as well as to explore the potential advantages of mechanical injectors within the field. This research and an industry analysis was further used to investigate the necessary components that would best accommodate the patent for a mechanical hand-held injector for the injection of dermal fillers.

Developments in commercial genetic testing have made it possible for people to find out a wealth of information that was previously difficult or impossible to obtain. Genetic testing is a novel solution to the adaptive problem of paternal uncertainty. We hypothesized that participants in the control condition would have greater interest in their paternal genetic information than their maternal genetic information and that participants who were cued to their dissimilarities with their father would seek out genetic information regarding their paternal side of the family above all other conditions. Neither of the two tested hypotheses were supported by the data. Analyses of several variables suggest that the manipulation did work to enhance perceptions of similarity and dissimilarity to parents, that participants were paying attention, and that the dependent variables were sensitive. Some incidental findings suggest that feelings of similarity, rather than dissimilarity, to father are related to interest in learning about paternal genealogy.

Description
The use of Artificial Intelligence in assistive systems is growing in application and efficiency. From self-driving cars, to medical and surgical robots and industrial tasked unsupervised co-robots; the use of AI and robotics to eliminate human error in high-stress environments and perform automated tasks is something that is advancing society’s status quo. Not only has the understanding of co-robotics exploded in the industrial world, but in research as well. The National Science Foundation (NSF) defines co-robots as the following: “...a robot whose main purpose is to work with people or other robots to accomplish a goal” (NSF, 1). The latest iteration of their National Robotics Initiative, NRI-2.0, focuses on efforts of creating co-robots optimized for ‘scalability, customizability, lowering barriers to entry, and societal impact’(NSF, 1). While many avenues have been explored for the implementation of co-robotics to create more efficient processes and sustainable lifestyles, this project’s focus was on societal impact co-robotics in the field of human safety and well-being. Introducing a co-robotics and computer vision AI solution for first responder assistance would help bring awareness and efficiency to public safety. The use of real-time identification techniques would create a greater range of awareness for first responders in high-stress situations. A combination of environmental features collected through sensors (camera and radar) could be used to identify people and objects within certain environments where visual impairments and obstructions are high (eg. burning buildings, smoke-filled rooms, ect.). Information about situational conditions (environmental readings, locations of other occupants, etc.) could be transmitted to first responders in emergency situations, maximizing situational awareness. This would not only aid first responders in the evaluation of emergency situations, but it would provide useful data for the first responder that would help materialize the most effective course of action for said situation.

Description
“Putting the ‘Home’ in Nursing Home” is a creative project that explores the idea that connecting nursing home residents with their family members via face-to-face virtual communication platforms will increase their happiness. While happiness is a highly discussed topic in our society, it is largely ignored when it comes to the older adult populations confined in nursing homes. Our society invests so much money keeping this group alive with little attention given to their happiness. This project has become more relevant during the current COVID-19 pandemic. While the original plan was to perform an in-person FaceTime demonstration with nursing home residents in Phoenix, Arizona during March 2020, the COVID-19 pandemic created a significant alteration in the project plans. Since nursing home facilities restricted all visitors, the foundation of this thesis/creative project became grounded in the literature review. The topics of happiness, loneliness, social isolation, and gerontechnology will be explored in depth as well as connecting their significance to the COVID-19 pandemic.

Description
Approximately 15,000 children die every day due to preventable illnesses (World Health Organization, 2016, 2017). Most of these deaths have been concentrated in developing countries and specifically in Sub-Saharan Africa, South Asia and to a lesser extent in Central Asia. Many studies have analyzed determinants of infant mortality rates across regions of South Asia. Despite neighboring South Asia, reasons for infant mortality in Central Asia do not seem to be as heavily researched. To investigate whether there are differences in the risk factors for infant mortality between South Asia and Central Asia, I analyzed data on 557,089 women and 1,272,916 children from Demographic Health Surveys and Multiple Indicator Cluster Surveys in 5 Central Asian (Azerbaijan, Kazakhstan, Kyrgyzstan, Uzbekistan, Tajikistan) and 5 South Asian (Afghanistan, Bangladesh, India, Nepal, Pakistan) countries. Binary logistic regression predicted whether a child was alive based on a number of maternal and child characteristics, including maternal age, maternal education, maternal residence, place of delivery, wealth, open defecation, prenatal care, and vaccinations. There were similarities along with differences in child survival outcomes between Central Asia and South Asia. Maternal age, maternal education, and the DPT 3 vaccination appeared to have protective effects on child survival rates in both Central Asia and South Asia whereas delivery outside of the hospital and open defecation have negative effects on child survival outcomes. Tetanus, polio 1, and the BCG vaccinations appeared to have a more pronounced positive effect on child survival in Central Asia whereas measles and polio 3 appear to have a more pronounced positive effect in South Asia. Wealth also appeared to have a greater protective effect in South Asia as opposed to Central Asia. More research needs to be conducted to elaborate on reasons for why there are differences between Central Asia and South Asia.

Background
Weight gain during the childbearing years and failure to lose pregnancy weight after birth contribute to the development of obesity in postpartum Latinas.
Methods
Madres para la Salud [Mothers for Health] was a 12-month, randomized controlled trial exploring a social support intervention with moderate-intensity physical activity (PA) seeking to effect changes in body fat, fat tissue inflammation, and depression symptoms in sedentary postpartum Latinas. This report describes the efficacy of the Madres intervention.
Results
The results show that while social support increased during the active intervention delivery, it declined to pre-intervention levels by the end of the intervention. There were significant achievements in aerobic and total steps across the 12 months of the intervention, and declines in body adiposity assessed with bioelectric impedance.
Conclusions
Social support from family and friends mediated increases in aerobic PA resulting in decrease in percent body fat.
