High Regression Rate Hybrid Rocket Fuel Grains With Helical Port Structures, Stephen A. Whitmore, Sean D. Walker, Daniel P. Merkley, Mansour Sobbi

Mechanical and Aerospace Engineering Faculty Publications

Results froma development campaign, where modern additive manufacturing methods are used to fabricate hybrid rocket fuel grains with embedded helical ports, are presented. The fuel grains were constructed from acrlyonitrile butadiene styrene using commercially available three-dimensional printer feedstockmaterial.Gaseous oxygen is used as the oxidizer for this test campaign.When compared to cylindrical fuel ports, significant increases in fuel regression rates were observed, and these increases in regression rate diminished with time as the helical fuel port burns to become progressivelymore cylindrical. Comparisons to the helical pipe flow skin friction correlation developed by Mishra and Gupta indicate that increased skin friction only …

Building A Discourse: Bridging The Gap Between New Media's Convergence And Rhetoric And Composition's Multimodality, Katherine G. Aho

Dissertations, Master's Theses and Master's Reports - Open

My dissertation emphasizes the use of narrative structuralism and narrative theories about storytelling in order to build a discourse between the fields of New Media and Rhetoric and Composition. Propp's morphological analysis and the breaking down of stories into component pieces aides in the discussion of storytelling as it appears in and is mediated by digital and computer technologies. New Media and Rhetoric and Composition are aided by shared concerns for textual production and consumption.

In using the notion of "kairotic reading" (KR), I show the interconnectedness and interdisciplinarity required in the development of pedagogy utilized to teach students to …

Dissertations, Master's Theses and Master's Reports - Open

By employing interpretive policy analysis this thesis aims to assess, measure, and explain policy capacity for government and non-government organizations involved in reclaiming Alberta's oil sands. Using this type of analysis to assess policy capacity is a novel approach for understanding reclamation policy; and therefore, this research will provide a unique contribution to the literature surrounding reclamation policy. The oil sands region in northeast Alberta, Canada is an area of interest for a few reasons; primarily because of the vast reserves of bitumen and the environmental cost associated with developing this resource. An increase in global oil demand has established …

The Hydrosocial Costs Of High-Volume Hydraulic Fracturing: A Tale Of Two Counties In Michigan, Amanda Kreuze

Dissertations, Master's Theses and Master's Reports - Open

Although natural gas has been praised as a clean and abundant energy source, the varying impacts and uncertainties surrounding the process of extracting natural gas from unconventional sources, known as horizontal high-volume hydraulic fracturing (HVHF) or “fracking,” have raised important concerns. The practice of HVHF is expanding so quickly that the full impacts are not yet known. This thesis project, using a grounded theory methodological approach, explores the risks and benefits associated with HVHF as recognized by the residents of two Michigan counties, one that currently produces natural gas by HVHF (Crawford County) and one that does not (Barry County). …

Engaging Metis: Exploring An African Woman's Negotiation Of Change, Ruby Pappoe

Dissertations, Master's Theses and Master's Reports - Open

African women’s emerging visibility as social and political actors has received a lot of attention in the past two decades. Scholars have explored women’s political movements and sociocultural activism from various perspectives to expose their contributions to social change. Although this scholarship has expanded to incorporate multiple voices as well as expose the contemporary strategies of resistance women engage in to overcome difficult challenges, there seems to be little research on ordinary women as they also confront their daily challenges in hope of improving their situations. This research takes up this gap by exploring a Ghanaian woman’s resistance in the …

Study Of Non-Reciprocal Dichroism In Photonic Structures, Anindya Majumdar

Dissertations, Master's Theses and Master's Reports - Open

Non-reciprocal phenomena are widely used in photonic devices. Important applications such as isolators and circulator waveguide structures depend on non-reciprocal effects. The basis of these phenomena is a difference in phase or refractive index for an electromagnetic wave of a given polarization as it travels through a medium in opposite directions. Generally this applies to the real part of the refractive index. The present report addresses a less studied phenomenon in non-reciprocal propagation, namely differences in optical absorption loss for a given polarization state in opposite propagation directions, a phenomenon we have termed non-reciprocal dichroism. Nonreciprocal dichroism can be defined …

Household Biosand Water Filters: Materials, Capacity, And Temperature Effects On Performance, Nathan B. Arnold

Dissertations, Master's Theses and Master's Reports - Open

The household biosand filter (BSF) is one of the world’s most utilized point-of-use (POU) water treatment tools where drinking water is not reliably potable. The feasibility of using ferrocement for construction, the filter volume, and the effect of temperature on removal are unclear, however. The following field and laboratory research was carried out in Panama and at Michigan Technological University. Field testing of ferrocement biosand filters (FBSFs) in rural Panama yielded average coliform and E.coli removals that compared favorably to plastic and cement BSFs. Parallel testing of a larger-bodied FBSF and a conventionally-sized BSF revealed that the former is necessary …

The Crisis Of Images: A Reading Of Feed A Child’S Controversial 2014 Advertisement, Marcel Tchatchou

Dissertations, Master's Theses and Master's Reports - Open

This work reads Feed A Child’s 2014 South African fund raising campaign advertisement (http://goo.gl/cRboV7) through Stuart Hall’s Encoding/Decoding model of communication. Utilizing concepts from Stuart Hall’s model this paper draws attention to racial questions raised by the commercial. Even though the commercial’s stated purpose is to raise awareness of unequal social conditions in South Africa, its visual elements are racially offensive. The turmoil generated by the commercial is the consequence of the complex structure of its message, and the fact that its meaning is not determined solely by the organization’s stated intentions. This work explores the way that the processes …

Dissertations, Master's Theses and Master's Reports - Open

The purpose of this study is to computationally model and analyze the vehicle frame which is mounted with a non-conventional, non-cylindrical compressed natural gas (CNG) fuel tank. Integration of this tank in the vehicle underbody will resolve the issue of reduced storage space which is observed in a conventional CNG powered vehicle. This research will ultimately result in making CNG a good alternative to gasoline and reducing the increasing dependency on a single fuel. This tank will be developed in two phases: phase I design of the tank will be a standard rectangular outer box shape with Schwarz P-surface inner …

An Analysis Of China’S Biofuels Policy And Chinese Discourse On Land Acquisition For Biofuels In Africa, Xuna Yang

Dissertations, Master's Theses and Master's Reports - Open

China has recently undertaken a very ambitious biofuel production program. However due to a lack of arable land domestically, this program has necessitated the leasing of arable land elsewhere (e.g., in Africa). This thesis first conducts a policy analysis of China’s biofuel policy using a historical institutionalism ends-and-means framework. The analysis reveals the ways in which China achieves its biofuel production goals through adopting various levels of policy means. China’s success in biofuel development is partly due to its unique policy-making and policy-assessment system, which ensures that biofuel production goals can be met. The second chapter analyzes China’s discourse on …

Reducing Releases Of Pahs: A Comparative Case Study Of Coal Tar Sealant Bans In The United States, Margaret Morrison

Dissertations, Master's Theses and Master's Reports - Open

Coal tar based sealants are applied to parking lots, driveways, and playgrounds in order to prevent pavements from deteriorating and cracking. Approximately 85 million gallons of coal tar based sealants are applied annually in the United States. In the mid-2000s scientists discovered that these type of sealants release polycyclic aromatic hydrocarbons (PAHs), which can be harmful to human and ecosystem health. After this discovery, dozens of city, county, and state wide bans of the product were put in place. However, some attempts at statewide bans have failed, while others have succeeded. This research examines the factors explaining the difference. These …

Mia40 Protein Serves As An Electron Sink In The Mia40-Erv1 Import Pathway, Sonya E. Neal, Deepa V. Dabir, Heather L. Tienson, Darryl M. Horn, Kathrin Glaeser, Rachel R. Ogozalek Loo, Antoni Barrientos, Carla M. Koehler

Biology Faculty Works

A redox-regulated import pathway consisting of Mia40 and Erv1 mediates the import of cysteine-rich proteins into the mitochondrial intermembrane space. Mia40 is the oxidoreductase that inserts two disulfide bonds into the substrate simultaneously. However, Mia40 has one redox-active cysteine pair, resulting in ambiguity about how Mia40 accepts numerous electrons during substrate oxidation. In this study, we have addressed the oxidation of Tim13 in vitro and in organello. Reductants such as glutathione and ascorbate inhibited both the oxidation of the substrate Tim13 in vitro and the import of Tim13 and Cmc1 into isolated mitochondria. In addition, a ternary complex consisting …

Numerical Study Of Structural Responses Of Rigid And Flexible Pavements Under Heavy Vehicles’ Loading, Rezwana Kabir

Dissertations, Master's Theses and Master's Reports

The highway system serves as the most critical transportation link in the economic development of a nation. In Michigan, about 74% of all the commodities delivered annually are transported by heavy trucks. The Michigan Department of Transportation (MDOT) permits multi-axle (11 axles) heavy truck with gross vehicle weight (GVW) limit of 164,000 lb., unlike many states having GVW limit of 80,000 lb. The effect of these heavy truck loadings on pavements might accelerate the rate of deterioration for flexible and rigid pavement structures. More detailed knowledge of the interaction of trucks with the pavement structure is essential for better management …

Flipping The Classroom To Teach Population Health: Increasing The Relevance., Vicki Simpson, Elizabeth Richards

School of Nursing Faculty Publications

In recent years, there have been multiple calls to enhance the population health and health promotion aspects of nursing programs. Further impetus has been provided by passage of the Affordable Care Act in 2010 with its focus on prevention. The need to develop students who can critically think and apply knowledge learned is crucial to the development of nurses who can integrate and apply the concepts of population-focused practice in society and a healthcare system undergoing transformation. This coupled with the ever changing needs of learners requires a different approach to content delivery and presentation. Flipped classroom courses, with an …

Cultural Differences In Preference Of Auditory Emoticons: Usa And South Korea, Myounghoon Jeon, Lee Ju-Hwan, Jason Sterkenburg, Christopher Plummer

Department of Psychology and Human Factors Publications

For the last two decades, research on auditory displays and sonification has continuously increased. However, most research has focused on cognitive and functional mapping rather than emotional mapping. Moreover, there has not been much research on cultural differences on auditory displays. The present study compared user preference of auditory emoticons in two countries: USA and South Korea. Seventy students evaluated 112 auditory icons and 115 earcons regarding 30 emotional adjectives. Results indicated that they showed similar preference in the same category (auditory icons or earcons), but they showed different patterns when they were asked to select the best sound between …

An Exploration Of Semiotics Of New Auditory Displays: A Comparative Analysis With Visual Displays, Myounghoon Jeon

Department of Psychology and Human Factors Publications

Communicability is an important factor of user interfaces. To address communicability, extensive research has been done on visual displays, whereas relatively little research has been done on auditory displays. The present paper attempts to analyze semiotics of novel auditory displays (spearcon, spindex, and lyricon) using Peirce’s classification of signs: icon, symbol, and index. After the aesthetic developmental patterns of the visual counterparts are presented, semiotics of auditory cues is discussed with future design directions.
