The inception of the human-powered water pump began during my trip to Maasailand in Kenya over the Summer of 2017. Being one of the few Broadening the Reach of Engineering through Community Engagement (BRECE) Scholars at Arizona State University, I was given the opportunity to join Prescott College (PC) on their annual trip to the Maasai Education, Research, and Conservation (MERC) Institute in rural Kenya. The ASU BRECE scholars that choose to travel were asked to collaborate with the local Maasai community to help develop functional and sustainable engineering solutions to problems identified alongside community members using rudimentary technology and tools that were available in this resource-constrained setting. This initiative evolved into multiple projects from the installation of GravityLights (a local invention that powers LEDs with falling sandbags), the construction/installation of smokeless stoves, and development of a much-needed solution to move water from the rainwater collection tanks around camp to other locations. This last project listed was prototyped once in camp, and this report details subsequent iterations of this human-powered pump.

Orbiting space debris is an active issue that affects the capability of space launch for future satellites, probes, and space shuttles, and it will become a nearly insurmountable problem without action. Debris of varying sizes and speeds orbit the Earth at a range of heights above the atmosphere and need to be removed to avoid damage to crucial equipment of active orbiting satellites including the International Space Station. Finding a feasible solution to space debris removal requires that several facets be covered to become a reality; these include being aware of the problem in magnitude and source. This literature assessment covers the magnitude of space debris in low-earth and geosynchronous orbit as well as collision events which have increased the amount of space debris. There have been efforts made by several space agencies to control the amount of space debris added to orbit by current and future launches over the last decade \u2014 serving as a temporary fix before removal can be executed. This paper explores known removal efforts through mitigation, projects conceived and tested by DARPA, related space policies and laws, CubeSat technology, and the cataloguing of known space debris. To make space debris removal a reality, roadblocks need to be removed to acquire permission from states or countries for space missions. For example, these restrictions are in place to protect the assets of several countries and organizations. Guidelines set to curb the growth of space debris fail to prevent the growth due to the restrictions for ownership rights making them not as effective. This paper covers space policy and laws, the economy, satellite ownership, international conflict, status of space debris, and the overall feasibility of space debris removal. It will then discuss currently proposed solutions for the removal of space debris. Finally, this paper attempts to weight the advantages and disadvantages of the idea that space debris removal should include the opportunity to recycle materials. For example, defunct satellites and other discarded space crafts could be used for future launches. It will conclude with a personal exploration of what materials can be recycled, what chemical processes can be used to break down materials, and how to combine recycling and chemical processes for space-based recycling stations between Earth and the moon. The overall question that drives the search for making space debris removal a reality is whether it is feasible in multiple areas including technologically, legally, monetarily, and physically.

Billions of people around the world deal with the struggles of poverty every day. Consequently, a number of others have committed themselves to help alleviate poverty. Many various methods are used, and a current consensus on the best method to alleviate poverty is lacking. Generally the methods used or researched exist somewhere on the spectrum between top-down and bottom-up approaches to fighting poverty. This paper analyzes a specific method proposed by C.K. Prahalad known as the Bottom of the Pyramid solution. The premise of the method is that large multinational corporations should utilize the large conglomerate of money that exists amongst poor people \u2014 created due to the sheer number of poor people \u2014 for business ventures. Concurrently, the poor people can benefit from the company's entrance. This method has received acclaim theoretically, but still needs empirical evidence to prove its practicality. This paper compares this approach with other approaches, considers international development data trends, and analyzes case studies of actual attempts that provide insight into the approach's potential for success. The market of poor people at the bottom of the pyramid is extremely segmented which makes it very difficult for large companies to financially prosper. It is even harder to establish mutual benefit between the large corporation and the poor. It has been found that although aspects of the bottom of the pyramid method hold merit, higher potential for alleviating poverty exists when small companies venture into this space rather than large multinational corporations. Small companies can conform to a single community and niche economy to prosper \u2014 a flexibility that large companies lack. Moving forward, analyzing the actual attempts provides the best and only empirical insights; hence, it will be important to consider more approaches into developing economies as they materialize.

In recent history, the world has been inspired to respond to the challenges faced by communities with ‘help’. This help has been administered with moderate success through community engagement strategies traditionally centered on social services provided through non-profit agencies. Social entrepreneurship has emerged in response to the lack of progress made in solving local and global issues with new innovations that have the potential to change the status quo and eliminate the problems for future generations. In social entrepreneurship, concerned individuals saw an opportunity to truly change the world. Higher education leaders have embraced social entrepreneurship, positioning university students as a driving force behind ideating creative and innovative solutions that can be implemented in communities to overcome a vast array of challenges from poverty to environmental sustainability. Despite the efforts of university staff and faculty, many student changemakers struggle to successfully implement their ideas and measure their impact. Factors such as how well the student understands the issue and community in addition to the extent to which the student is experienced in ideation, creative-problem solving, and implementation of projects contribute to the success or failure of a student social effort. Inspired by their experiences serving as director of Changemaker Central, the authors sought to understand the process of preparing students to be agents of change in the community. Having observed the variance in success among aspiring changemakers at Arizona State University (ASU), the researchers studied how to best support students in preparation for a high-impact career. The research analyzed students’ experiences in two of ASU’s social change programs, Changemaker Challenge (CC) and University Service-Learning (USL) and found a need for more cohesion between two programs and their represented methodologies in addition to a need for in-depth analysis on the student journey.

The objective for Under the Camper Shell was to build a prototype of a full living environment within the confines of a pickup truck bed and camper shell. The total volume available to work with is approximately 85ft3. This full living environment entails functioning systems for essential modern living, providing shelter and spaces for cooking, sleeping, eating, and sanitation. The project proved to be very challenging from the start. First, the livable space is extremely small, being only tall enough for one to sit up straight. The truck and camper shell were both borrowed items, so no modifications were allowed for either, e.g. drilling holes for mounting. The idea was to create a system that could be easily removed, transforming it from a camper to a utility truck. The systems developed for the living environment would be modular and transformative so to accommodate for different necessities when packing. The goal was to create a low-water system with sustainability in mind. Insulating the space was the largest challenge and the most rewarding, using body heat to warm the space and insulate from the elements. Comfort systems were made of high density foam cushions in sections to allow folding and stacking for different functions (sleeping, lounging, and sitting). Sanitation is necessary for healthy living and regular human function. A composting toilet was used for the design, lending to low-water usage and is sustainable over time. Saw dust would be necessary for its function, but upon composting, the unit will generate sufficient amounts of heat to act as a space heater. Showering serves the functions of exfoliation and ridding of bacteria, both of which bath wipes can accomplish, limiting massive volumes of water storage and waste. Storage systems were also designed for modularity. Hooks were installed the length of the bed for hanging or securing items as necessary. Some are available for hanging bags. A cabinetry rail also runs the length of the bed to allow movement of hard storage to accommodate different scenarios. The cooking method is called "sous-vide", a method of cooking food in air-tight bags submerged in hot water. The water is reusable for cooking and no dishes are necessary for serving. Overall, the prototype fulfilled its function as a full living environment with few improvements necessary for future use.

"Seventy five percent of the world's poor live in rural areas of developing countries, where most people's livelihoods rely directly on agriculture." (USAid, 2014) Reduced levels of crop production and the accompanying problems of malnourishment exist all over the world. In rural Peru, for example, 11 percent of the population is malnourished. (Global Healthfacts.org, 2012) Since the success in agriculture relies importantly on the fertility of the soil, it is imperative that any efforts at reversing this trend be primarily directed at improving the existing soils. This, in turn, will increase crop yields, and if done properly, will also conserve natural resources and maximize profits for farmers. In order to improve the lives of those at the bottom of the pyramid through agriculture, certain tools and knowledge must be provided in order to empower such persons to help themselves. An ancient method of soil improvement, known as Terra Preta do Indio (Indian dark earth), was discovered by Anthropologists in the 1800's. These dark, carbon-rich, soils are notable for their high fertility, high amounts of plant available nutrients, and their high moisture retention rates. The key to their long-lasting fertility and durability is the presence of high levels of biochar, a highly stable organic carbon \u2014 produced when organic matter (crop residues, food waste, manure, etc.) is burned at low temperatures in the absence of oxygen. Research has shown that when charcoal (biochar) and fertilizers are combined, it can yield as much as 880 percent more than when fertilizers are used by themselves.

I. Executive Summary Projectors are used in more and more live and corporate events and theatrical productions. In these environments, they are subject to a myriad of conditions. These can include extreme temperatures, atmospheric effects and contaminates, shipping and rough handling, and power issues. The goal is to find ways to extend the reliable and economical lifespan of these machines increasing companies ROI and decreasing environmental damage from more frequent production, repair and disposal. The first area studied was the effect removing the covers has on the projector performance. This is important knowledge for both the research protocols followed in this research and in normal use during maintenance and repair. Testing demonstrated that the removal of covers on small consumer projectors has a profound impact on internal temperatures and can even cause overheating due to the covers being used as air ducting. The main focus of this project was finding effective pre-filters for use around haze, fog and other airborne contaminates. This was successful with two material being demonstrated to be cost effective, filter far superior to factory filters alone, and produce acceptable impacts on projector cooling in several models and types of projector. These filters cost typically less than $1 per filter and reduce the ingress of contaminates by 60-80%. Additionally the effects of improper shutdown versus the manufacturers specified shutdown process were tested. It was determined that the projectors where power was unplugged or turned off had components exceed both operating temperatures and temperatures during the normal shutdown. This shows that following the correct shutdown process keeps components cooler leading to a longer component life and therefore longer projector life and decreased repairs.

Although wind turbine bearings are designed to operate 18-20 years, in the recent years premature failure among these bearings has caused this life to reduce to as low as a few months to a year. One of the leading causes of premature failure called white structure flaking is a mechanism that was first cited in literature decades ago but not much is understood about it even today. The cause of this mode of failure results from the initiation of white etched cracks (WECs). In this report, different failure mechanisms, especially premature failure mechanisms that were tested and analyzed are demonstrated as a pathway to understanding this phenomenon. Through the use of various tribometers, samples were tested in diverse and extreme conditions in order to study the effect of these different operational conditions on the specimen. Analysis of the tested samples allowed for a comparison of the microstructure alterations in the tested samples to the field bearings affected by WSF.

A Guiding Hand: Grief Response in Young Adults works to guide young adults thought the grieving process after the traumatic death of a loved one. It goes through the steps of grieving and what a person can expect when they suddenly lose someone dear. Written from the point of view of someone who had lost their best friend in a murder/suicide, A Guiding Hand, shares a personal view that is often missing in other books on grief. This piece works to prepare other young adults for the unexpected emotions that are associated with grief. It also works to provide coping strategies to help recover from a traumatic loss in a healthy manner and to put people in touch with resources they may not know exist in order to help with healing.

In this study, we propose and then assess the efficacy of a new approach to static suspension to correct for facial paralysis. Our method involves placing barbed sutures through the superficial muscular aponeurotic system (SMAS) and anchoring them in the temporal fascia parallel to the underlying facial muscles. We first analyzed the ability of this procedure to improve facial symmetry by comparing the degree of asymmetry between the paralyzed and unaffected sides of a patient's face (N=10) prior to and following surgery. Then, to determine if symmetry is improved as a result of placing the sutures parallel to the direction of facial muscle forces, we measured the vectors of levator labii superioris and zygomaticus major in cadaver hemifaces (N=3) and compared them to the angles of the vectors of correction from the patient sample to angles of muscle vectors in three facial hemispheres from cadaver controls. Results indicate that: (1) facial symmetry was significantly improved in these patients and (2) this improvement. We conclude that, compared to existing protocols, our novel surgical method is a better means of static suspension for reconstruction following onset of facial paralysis as it is simple to perform, easy to replicate, able to be post-operatively adjusted in-office, has a good long-term prognosis, and, as we have demonstrated, effectively corrects the appearance of asymmetry by working with the underlying facial anatomy.
