Ulaanbaatar, Mongolia is one of the world’s coldest capital cities with roughly 1.5 million residents. About fifty percent of the city’s residents are off the electrical grid and millions continue to live nomadic lifestyles, raising livestock for food. Problematically, residents often turn to raw coal - Mongolia’s largest export - as a means to cook food and stay warm. Project Koyash is a philanthropic engineering initiative that was founded in the Arizona State University Program Engineering Projects in Community Service (EPICS) to combat the air quality crisis plaguing the ger districts of Ulaanbaatar. Koyash has already deployed 13 fully functional and autonomous units consisting of a solar powered air filtration system in Ulaanbaatar. Koyash innovated a solution of solar panels, air filters, batteries, inverters, PCB Arduinos, and other necessary components for providing crucial humanitarian services. The team is working to send more units and develop a local supply chain for the systems. This thesis project explores the development of Koyash, assesses the human health implications of air pollution, and reflects on the entire process.

The aim of this study is to characterize whether a superoxide dismutase (SOD) mimic, Mn3, will act as a radio-sensitizer in tumor cells and radio-protector in normal brain cells. Immunohistochemistry assesses efficacy of treatment mice. A preliminary experiment compares different levels of protein expression at varied timepoints following radiation to provide a baseline for further experimental findings. The first experiment examines the effects of Mn3 and ionizing radiation in U87 tumor cells injected into the flank of nude mice. The second examines the drug's ability to protect normal brain tissue from ionizing radiation in the normal brain containing no tumor. The third study examines the drug’s efficacy in radio-sensitization and radio-protection on mice with the U87 tumor cell line injected intracranially. Results show that in regular brain tissue, non-tumor cells exhibit less oxidative damage and a lower microglia response when treated with the SOD mimic compared to control. In flank tumor tissue, mice treated with the SOD mimic show increased oxidative damage and DNA breakage in the tumor regions. Mice with intracranial tumors show increased DNA oxidation in the tumor of the Mn3 treatment group when compared to the irradiation group.

Logos are a vital part of a company’s brand. They are what catches people’s eyes and is a symbol that people associate the company with. Even if one forgets the name of a company or what they specialize in, a memorable and unique logo can linger within an individual's mind and can keep the memory of a specific company alive in their minds. In my thesis project, I am combining the fields of marketing and visual cognition to measure and research if there are specific visual aspects of a logo people instinctively associate with different brand adjectives: sustainability, trustworthiness, and modern.

Analysis and Development of Cognition Tests for Pre-Diagnostic Strategies for Alzheimer’s Disease

Alzheimer's disease (AD) is characterized by the progressive loss of cognitive function and memory, and is the most common cause of dementia. Alzheimer's disease targets the brain and is associated with the accumulation of abnormal protein aggregates that disrupt neural network communication and lead to various facets of cognitive decline. Current problems in AD research originates from the inability to identify individuals that are at risk. With the limitations of patients already displaying signs of neurodegeneration, strategies for prevention are not effective. Through developing a comprehensive cognitive test that tests a range of mental abilities, data can be collected, and a longitudinal study can be proposed to track cognitive decline in a multifaceted approach over a period of time. Previous literature indicates that functional decline is present years before the manifestation of symptoms in Alzheimer’s disease. Identifying pre-diagnostic cognitive and functional changes could lead to an improved and wider selection for preventive treatment trials. By designing a comprehensive cognitive experiment, an initial data set was obtained, and trends related to time and answer response were analyzed. The scope, applications and limitations within this experimental design is discussed, and future directions are proposed.

Alongside the many challenges of Covid-19, the pandemic also disrupted the normal structure of education for students. As classes were being transferred to online formats, computer science students started learning more through constructivism principles rather than the traditionally taught, in-person lectures. This quantitative assessment hopes to determine whether constructivist principles or traditional/visual cognition principles are better for teaching computer science topics. Determinations will be made through a social behavioral experiment teaching pointers to participants. Participants were split into three groups: a control group, a constructivist group, and a visual cognition group. Each group took part in an assessment testing their knowledge retention about pointers after having a lecture based around each teaching method. The assessment evaluated retries per assessment, time per correct answer, time per question, and the average time taken in total. The results of the experiment led to a conclusion that, according to the resulting data, constructivism teaching principles benefited participant scores, and visual cognition teaching principles worsened participant scores. However, a definitive answer of which teaching method is better for computer science could not be made due to insufficient sample size. When reflecting on the first iteration of this experiment, it is clear that future iterations of this experiment would benefit from a higher sample size, an easier assignment for the constructivist group, a feedback survey, and a longer period to experiment.

As the pandemic hit back in 2019, an influx of pet adoptions occurred as more people were spending time home alone and saw the need for a companion. While SARS-CoV-2 is still circulating the globe, and mutating into different strains, people are continuing to work from home close to their animals. Evidence has shown that animals like dogs, cats, minks, and ferrets can contract the disease from their human counterparts, however, it is unclear if humans can contract the disease back from their animal companions [6]. While we have seen these Coronavirus outbreaks continually occur in the past several decades, we must be properly knowledgeable on the transmission capabilities of the virus to combat another wave of a SARS outbreak for future decades to come. Earlier coronavirus’ present in veterinary medicine has been noted to progress into more fatal and aggressive diseases when transmitted from one species to another [7], and therefore it is just as important that we understand the transmission possibilities of the virus in animals as we do ourselves. To determine if our pets can transmit the virus to us humans, a study is proposed where canines are purposefully inoculated with a selected SARS-Cov-2 virus and exposed to human volunteers to determine if the virus can spill back from canines to humans. To determine which virus strain will be utilized for the study, data regarding potential strain hosts will be collected from directly ill volunteers who also own canines prior to inoculation.

Eel Farming: A Theoretical Research Design on Improving the Success of Eel Reproduction in Captivity

This thesis’s goal was to design a theoretical research study based on a literature review on improving the aquaculture of European eels. Aquaculture is the farming of aquatic species such as fish. The European eel is a critically endangered catadromous fish species that faces a continuous decline in wild populations over the years due to pollution, climate change, industrial development, and overfishing. The replenishing of the fishery stock of European eels relies heavily on the wild population since there is no sustainable way of creating a generational captive population. The reason for this is that the lifecycle and environmental triggers of freshwater eels are relatively unknown due to their long lifespan, migratory lifestyle, metamorphoses, and sex differentiation timing. The primary focus of the design was to use different hormonal regiments and compared their effects on hatch rate, clutch size, survival rate, and lifespan of the juvenile eels. From this, it was concluded that the mother eel’s lipid storage impacts the quality of yolk sacs which in turn impacts the survival of leptocephali (eel larvae). The primary focus on eel population recovery should be habitat restoration and research on the leptocephalus stage since they both have the most evidence of success in eel population recovery.

Globally, breast cancer is the most common cancer in women. The disease and treatment cause many unfavorable symptoms such as fatigue, pain, and psychological stress. Research suggests that stress may negatively impact survival and recurrence outcomes of breast cancer patients. Cognitive-behavioral stress management (CBSM) programs have been found to improve these outcomes. In this thesis, I propose using virtual reality as a tool for CBSM to improve symptoms and outcomes for non-metastatic breast cancer patients.
