Evaluating the North St Paul City Redevelopment Process
No full textReport, presentation and handout completed by students enrolled in OLPD 5501: Principles and Methods of Evaluation, taught by Randi Nelson in fall 2013.This project was completed as part of the 2013-2014 Resilient Communities Project (rcp.umn.edu) partnership with the City of North St. Paul. North St. Paul had a goal of becoming a “redevelopment ready” community, a designation given by the Urban Land Institute. In 2011, the city also applied for a Metropolitan Council livable cities grant. To reach these goals, project lead Paul Ammerman collaborated with students in OLPD 5501: Principles and Methods of Evaluation, taught by Randi Nelson, to evaluate the City’s redevelopment proposal. The students identified stakeholders, set the context for the evaluation, and offered an evaluation proposal. The final report, presentation, and handout are available.This project was supported by the Resilient Communities Project (RCP), a program at the University of Minnesota whose mission is to connect communities in Minnesota with U of MN faculty and students to advance community resilience through collaborative, course-based projects. RCP is a program of the Center for Urban and Regional Affairs (CURA). More information at http://www.rcp.umn.edu.Ologbosere, Itohan; Goldbeck, Briana; Zji, JingJing; Foley, Kari. (2013).

No full textFebruary 12th, 2016 starts out like any other day for author Briana Owens, but it won’t stay that way for long. After a series of disappointing events, Owens finds herself stranded in a parking lot with a car that won’t start, and decides enough is enough—she’s ready to make a big change in her life. In this personal narrative, Owens introduces herself, her family, and the circumstances that led to her first year at Kennesaw State University. Though she faces several challenges along the way, Owens is determined to be the first in her family to go to college, and she won’t give up before she turns her dream into a reality
The Social Lives of Pots and Potters in the Kathmandu Valley
No full textThis paper investigates the changing status of ceramics in Thimi, Nepal. Pottery in the Kathmandu Valley is an ancient tradition, dating as far back as 400 AD. However, the rich craft is currently at a crossroads between extinction and innovation. The author’s project is to trace the lives of pots and the potters from the mid 20th century until present as they are imagined, remembered, and enacted by the human and clay inhabitants of Thimi. Rather than focusing on the aesthetic properties of pots, the author instead emphasizes the social relations that both surround and encounter them. This method aims to shed light on how and by whom clay is transformed into a functional and culturally meaningful object. In conclusion, the author addresses potential futures for the disappearing pots and potters of Thimi

Armor, Heirloom, Bauble: Three Case Studies on Tibetan Jewelry
No full textJewelry practices in Tibet have been portrayed in past scholarship as entangled in the worldly vices of indulgence and wealth display. According to this reading, a study of bodily adornment in Tibet has no place within the field of religious studies. Though pristine when gracing the cold metal of the icon, or when held as an object of meditation by the spiritual master, the vain enterprise of decorating the fleshly lay body wrenches ornamentation from the “world beyond” and drags it back into the quagmire of cyclic existence. In this thesis, I challenge the reductionist readings to which bodily adornment has regularly been subject, and argue that the long-standing and varied practices surrounding bodily adornment in Tibet, luxurious and otherwise, cannot be determined by a single social function or motivating factor. Chapter one centers on jewelry in the line of fire, where protective adornment can mean the difference between life and death. Chapter two shifts focus to women’s ornamented bodies, juxtaposing descriptions of Tibetan jewelry in nineteenth-century European travel accounts with the recollections of a Tibetan aristocratic woman. The final chapter zeroes in on the role of bejeweled heirlooms in the court of the Fifth Dalai Lama, to explore the mnemonic power of jewelry and its entanglement in the politics of reincarnation. Throughout these three case studies on Tibetan jewelry, I insist on conceptualizing jewelry while it graces the moving body in order to account for the embodied experience of adornment
Analysis and optimization of a new accident tolerant fuel called fuel-in-fibers
No full textThesis: S.M., Massachusetts Institute of Technology, Department of Nuclear Science and Engineering, 2018.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Cataloged from student-submitted PDF version of thesis.Includes bibliographical references (pages 64-68).The 2011 Fukushima Daiichi accident highlighted the weakness of the current nuclear fuel and motivated R&D of accident tolerant fuels. Accident tolerant fuels (ATF) are fuels that can tolerate loss of active cooling in the core of light water reactors (LWRs) for a considerably longer period of time while maintaining or improving the fuel performance during normal operations. Fully Ceramic Microencapsulated (FCM) fuel is an ATF concept aimed at significantly increasing the fission product retention capability of nuclear fuel at high temperatures. The FCM concept is made up of fuel particles surrounded by multilayers of ceramic material similar to the TRISO fuel concept. The fuel particles are embedded in a SiC matrix in cylindrical pellet geometry which gives the fuel its high temperature corrosion resistance. However, when implementing the FCM concept in a conventional PWR fuel geometry, it is not possible to maintain an 18 month fuel cycle length and remain below the proliferation enrichment limit of 20 w/o U₂₃₅. This is a critical challenge that needs to be overcome in order to benefit from the high temperature fission product retention capability of FCM-type ATF concepts. Therefore, this work aims at investigating the potential benefits of a new accident tolerant fuel, Fuel-in-Fibers (F-in-F) concept. The Fuel-in-Fibers concept was created by Free Form Fibers, a laser chemical vapor deposition direct manufacturing company. It aims to combine the same robust fission product retention and high temperature stability as the FCM fuel concept while drastically decreasing the necessary fuel enrichment. This is done by designing a fuel fiber in cylindrical geometry as opposed to spherical particles to increase the packing fraction within a cylindrical pellet. The direct manufacturing allows for minimization of the volume occupied by the SiC matrix as well as direct deposition of high density fuels like uranium nitride (UN). Assembly level calculations in the Monte Carlo code SERPENT determined that the Fuel-in-Fibers concept could maintain a typical PWR cycle length with less than 20 w/o U₂₃₅ (LEU) enrichment. The fibers in the fuel pellet were then homogenized for use in lattice physics code CASMO and core simulator code SIMULATE3. The SIMUALTE full core simulation showed that the Fuel-in- Fibers design required enrichments of 8% and 6% for UO2 and UN as fuels, respectively. Overall, the full core analysis of a standard 4-loop Westinghouse PWR showed Fuel-in-Fibers concept has similar behavior as the conventional fuel. Due to the high fissile enrichments, the calculated radial power peaking factors were higher in Fuel-in-Fibers concept. This may result in decrease of the coolant outlet temperature by 5 K in order to maintain safety margins. The shutdown margin analysis showed that using B4C instead AgInCd control rods is needed. A design optimization was also performed to calculate the ideal geometry for Fuel-in-Fibers concept. An in-house MATLAB single channel code, built to evaluate PWR Thermal Hydraulic and Structural performance, was used to vary the fuel pin Pitch and Pitch-to-Diameter ratio (P/D Ratio). The results showed that a smaller pitch and larger diameter of 13.2 mm and 12 mm, respectively will improve the Fuel-in-Fibers concept enrichment requirements. A simplified economic analysis based on highly uncertain fabrication cost estimates was performed. The economics analysis determined that the fuel in fiber design is estimated to cost more than current UO₂ fuel by 1.25x - 15x due to the increased enrichment and fabrication costs but may be offset by the additional safety margins provided by the Fuel-in-Fibers concept.by Briana Hiscox.S.M
