Item Health Effects of Water Reuse by Groundwater Recharge(University of Texas at Austin, 1980-09) Himmelblau Nellor, M.A.Item Models for Water Reuse Planning(University of Texas at Austin, 1980-08) Sanchez, G.O.; Mays, L.W.Item Packaging Design in the Circular Economy: Reuse Models in Fast-Moving Consumer Goods(2022) Gray, MadisonMultinational fast-moving consumer goods corporations such as Procter & Gamble, Unilever, and Coca-Cola are the highest producers of plastic pollution in the world, and yet take little-to-no responsibility for the waste after the end of their product’s useful life. Single-use plastics, such as those used for bottles, wrappers, straws, bags, and more, end up wasted in landfills, waterways, and ecosystems all around the world. The challenges associated with managing large and diverse streams of waste are complex, and the repercussions can be far-reaching, but the circular economy has proved to be promising in eliminating some of this stress. The circular economy is a proposed economic system aimed at eliminating waste and the continual use of resources and has tremendous organizing potential. In this thesis, I will discuss the catastrophic impact of the United States’ single-use plastics addiction and evaluate the reusable methods of packaging among various types of household products in an attempt to drastically cut single-use plastics output. I will specifically focus on the opportunities and challenges of “refillables,” or items where consumers can easily obtain regular household items in bulk. I will evaluate similar circular economy projects that already exist in the market using reuse models, such as the Unboxed Market in Canada that has completely eliminated single-use plastics, and create a cost-savings model to demonstrate how a company can implement circular economy into their overall strategy.Item Recyclability of 304L Stainless Steel in the Selective Laser Melting Process(University of Texas at Austin, 2018) Sutton, Austin T.; Kriewall, Caitlin S.; Leu, Ming C.; Newkirk, Joseph W.During part fabrication by selective laser melting (SLM), a powder-bed fusion process in Additive Manufacturing (AM), a large amount of energy is input from the laser into the melt pool, causing generation of spatter and condensate, both of which have the potential to settle in the surrounding powder-bed compromising its reusability. In this study, 304L stainless steel powder is subjected to five reuses in the SLM process to assess its recyclability through characterization of both powder and mechanical properties. Powder was characterized morphologically by particle size distribution measurements, oxygen content with inert gas fusion analysis, and phase identification by X-ray diffraction. The evolution of powder properties with reuse was also correlated to tensile properties of the as-built material. The results show that reused powder coarsens and accrues more oxygen with each reuse. The effects of powder coarsening and oxygen increase on the tensile properties of fabricated parts are being investigated.Item Remaking the Pitch: Reuse Strategies in Entrepreneurs' Pitch Decks(IEEE, 2015-04) Spinuzzi, Clay; Nelson, Scott; Thomson, Keela S.; Lorenzini, Francesca; French, Rosemary A.; Pogue, Gregory; Burback, Sidney D.; Momberger, JoelResearch problem: Examines how Korean entrepreneurs in an entrepreneurship program revised their English-language slide decks for their competitive presentations (“pitches”) by reusing content from professional communication genres, including both their own documents and feedback from potential stakeholders in their target markets. Research question: As entrepreneurs learn to pitch ideas to unfamiliar markets, how do they revise their slide decks by reusing content from other professional communication genres? Specifically, what strategies do they follow when reusing content? Literature review: The professional communication literature demonstrates that reuse tends to take place in documentation cycles in which documents are set in interaction with each other and that reuse itself involves rhetorical choices. Yet such reuse strategies have not been examined in existing studies of entrepreneurial pitches in marketing and technology commercialization. Methodology: In an exploratory qualitative study, researchers textually analyzed 14 sets of five related document genres in the archives of an entrepreneurship program. These genres represented a full cycle of activity: application to the program, initial pitches, initial feedback from program personnel, detailed feedback from representative stakeholders in the target market, and revised pitches. Interviews and surveys of program personnel further contextualize the data. Results and conclusions: Entrepreneurs reused content from professional communication genres, including those that they had generated as well as those generated by market stakeholders. However, reuse went beyond simply accepting and copying feedback; as they learned to make their pitch arguments, these entrepreneurs had to weigh this feedback and engage with it critically. This reuse can be characterized as Accepting (repeating verbatim or in close paraphrase); Continuing (extending lines of argument); and Resisting (rebutting lines of argument). These findings suggest that entrepreneurs need all three strategies as they refine their pitches for their target markets.Item Trinity River Basin Master Plan(Trinity River Authority, 2007) Trinity River Authority
