Description
This study is a feminist historiography of Al-Raida, a Lebanese feminist journal introduced in 1976 by the Institute for Women's Studies in the Arab World at the Lebanese American University. This study recovers foundations of modern Lebanese feminist discourses as they are articulated in the journal by employing Foucauldian CDA as a means to trace discourse strands, or conversations, which include Family Planning, development, politics and narratives of the Lebanese civil war. This study explores, by situating each discourse strand within dominant and local historical contexts, the shifting rhetorical function of the journal through various historical moments. Tracing the dominant discourse strands within the first decade of the journal, this study rhetorically analyzes the ways in which arguments are positioned, research studies are presented, and methodologies are employed to forge viable solutions to Middle Eastern women's issues. First, the study traces the conversation on Family Planning in Lebanon and its relevance to the economic and social situation during the late 70s. Second, the study presents the shift in the early 80s towards a discourse on development and explores how Al-Raida presents the issue of development, attempts to define it, and in doing so outlines some of the concerns at this time, including illiteracy, access to health care, access to paid employment, and women's access to developmental opportunities. Third, the study presents the discourse in the mid-80s on the civil war in Lebanon and highlights Al-Raida's rhetorical function by documenting trauma and war narratives through personal interviews, testimonies, and ethnographies. The shift in the methodologies of the research articles published in the first decade, from quantitative studies towards qualitative studies, indicates the journal is rhetorically situated within both the dominant international discourse and within the local context, exhibiting an ability to respond to the nuances in the local Lebanese women's movement while simultaneously maintaining international visibility.

Description
ABSTRACT For many years, difference scholars, such as Cornel West, Iris Marion Young, and Janet Atwill have been reminding humanities scholars that if social equity is ever to be realized, difference needs to be reconfigured and reframed. As Janet Atwill puts it, "difference can no longer be the anomaly, the enemy, or the problem to be solved. Difference is the condition" (212). While these scholars insightfully recognize that difference needs to be accepted, welcomed and loved rather than merely tolerated, they have not sufficiently addressed the perceptual change that must occur worldwide if difference as an intrinsic underlying condition of human existence is to be embraced. This project provides a point of departure for carrying out such a dramatic epistemic change by arguing that hierarchical thinking, not difference, is the real agent underwriting societal violence and discord. Hierarchical thinking delineates a more appropriate critical space than does difference for social justice inquiry, invention, and intervention. This project also rhetorically theorizes the realm of intersubjectivity and provides two novel contributions to contemporary rhetorical theory: 1) privilege as a rhetorical construct and 2) the untapped inventional potential of the postmodern understanding of intersubjectivity. To illustrate the embodied and performative aspects of hierarchical thinking, this work draws upon the writings of Lillian Smith, a white southerner (1897-1966) whose descriptive analyses of the Jim Crow South allude to large systems of privilege of which Jim Crow is merely representational. Illustrating the invidious nexus of privilege, Smith's writings describe the ways in which individuals embody and perform practices of exclusion and hate to perpetuate larger systems of privilege. Smith shows how privilege operates much as gender and power--fluidly and variously and dependent upon context. Viewing privilege as a rhetorical construct, operating dynamically, always in flux and at play, provides rhetoricians with a theoretically important move that un-yokes privilege from specific identities (e.g., white privilege). When viewed through this more dynamic and precise lens, we can readily perceive how privilege functions as a colonizing, ubiquitously learned, and variegated rhetorical practice of subordination and domination that, as a frame of analysis, offers a more fluid and accurate perspective than identity categories provide for discussions of oppression, social justice, and democratic engagement.

Description
This longitudinal exploratory research study examines a Russian language online community of creative writers who refer to themselves as Real Padonki. Grounded theory was used as the method of data collection and analysis. Based on analysis of the texts published on udaff.com and interactions between the members of this community several conclusions were made. It is proposed that udaff.com should be viewed as an online resource for writers who have created a new form of literature: post-Soviet Russian literature. This new of form literature is characterized by several features that distinguish it from previous forms. This new form of literature is based on the cultural model of a Real Padonak - a new kind of person that embodies both the writer and the hero (a new archetype) created by this writer. In the same way as dissident writers made criminal argot a part of Russian literature, the writers of udaff.com rely on the use of Albanskij, a linguistic innovation, a variation of the Russian language that they have created. Finally, this new literature uses the Internet as its main medium of publication. As a new archetype, Real Padonak represents a continuum of characters (real life people as well as invented literary characters) created by udaff.com writers. From the perspective of Discourse analysis, the cultural model of Real Padonak is shown as multiglossia of Discourses that represent beliefs, attitudes, values, and practices that exist in contemporary Russian society.

Description
This dissertation is an examination of a modernist desire to construct future materiality via material language, which represents a desire to overcome biology and the biological body. As such, modernist discourses of material language must be understood within their broader historical context, as these textual constructs developed against a cultural backdrop replete with eugenicist ideologies. Modernists wielded discourses of material language to determine via cultural reproduction which futures might materialize, as well as which bodies could occupy those futures and in what capacities. This dissertation argues that these modernist constructs contain their own failure in their antibiologism and their refusal to acknowledge the agency of corporeal materiality before them. Unlike language, the body expresses biopower through its material (re)productivity—its corpo-reality—which, though it can be shaped and repressed by discourse, persistently ruptures through the restraints of eugenicist ideologies and the autonomous liberal model of white masculine embodiment they uphold. This work analyses sexually marginalized bodies in texts by Mina Loy, Djuna Barnes, Nathanael West, and Ernest Hemingway that, through their insistently persistent biological materiality, disrupt modernist discourses of material language that offer no future for feminine, queer, and disabled corporeality. By exploring how intersecting issues of gender, sexuality, and disability complicate theories of language’s materiality in modern American literature, this dissertation brings attention to writers and texts that challenge broader attempts in the early decades of the twentieth century to subvert the biological body through eugenicist projects of cultural reproduction.

Description
The purpose of this study was to observe the effectiveness of the phenylalanyl arginine β-naphthylamide dihydrochloride inhibitor and Tween 20 when combined with an antibiotic against Escherichia. coli. As antibiotic resistance becomes more and more prevalent it is necessary to think outside the box and do more than just increase the dosage of currently prescribed antibiotics. This study attempted to combat two forms of antibiotic resistance. The first is the AcrAB efflux pump which is able to pump antibiotics out of the cell. The second is the biofilms that E. coli can form. By using an inhibitor, the pump should be unable to rid itself of an antibiotic. On the other hand, using Tween allows for biofilm formation to either be disrupted or for the biofilm to be dissolved. By combining these two chemicals with an antibiotic that the efflux pump is known to expel, low concentrations of each chemical should result in an equivalent or greater effect on bacteria compared to any one chemical in higher concentrations. To test this hypothesis a 96 well plate BEC screen test was performed. A range of antibiotics were used at various concentrations and with varying concentrations of both Tween and the inhibitor to find a starting point. Following this, Erythromycin and Ciprofloxacin were picked as the best candidates and the optimum range of the antibiotic, Tween, and inhibitor were established. Finally, all three chemicals were combined to observe the effects they had together as opposed to individually or paired together. From the results of this experiment several conclusions were made. First, the inhibitor did in fact increase the effectiveness of the antibiotic as less antibiotic was needed if the inhibitor was present. Second, Tween showed an ability to prevent recovery in the MBEC reading, showing that it has the ability to disrupt or dissolve biofilms. However, Tween also showed a noticeable decrease in effectiveness in the overall treatment. This negative interaction was unable to be compensated for when using the inhibitor and so the hypothesis was proven false as combining the three chemicals led to a less effective treatment method.

Description
An in-depth analysis on the effects vortex generators cause to the boundary layer separation that occurs when an internal flow passes through a diffuser is presented. By understanding the effects vortex generators demonstrate on the boundary layer, they can be utilized to improve the performance and efficiencies of diffusers and other internal flow applications. An experiment was constructed to acquire physical data that could assess the change in performance of the diffusers once vortex generators were applied. The experiment consisted of pushing air through rectangular diffusers with half angles of 10, 20, and 30 degrees. A velocity distribution model was created for each diffuser without the application of vortex generators before modeling the velocity distribution with the application of vortex generators. This allowed the two results to be directly compared to one another and the improvements to be quantified. This was completed by using the velocity distribution model to find the partial mass flow rate through the outer portion of the diffuser's cross-sectional area. The analysis concluded that the vortex generators noticeably increased the performance of the diffusers. This was best seen in the performance of the 30-degree diffuser. Initially the diffuser experienced airflow velocities near zero towards the edges. This led to 0.18% of the mass flow rate occurring in the outer one-fourth portion of the cross-sectional area. With the application of vortex generators, this percentage increased to 5.7%. The 20-degree diffuser improved from 2.5% to 7.9% of the total mass flow rate in the outer portion and the 10-degree diffuser improved from 11.9% to 19.2%. These results demonstrate an increase in performance by the addition of vortex generators while allowing the possibility for further investigation on improvement through the design and configuration of these vortex generators.

Description
The objective of this project was to design an electrically driven centrifugal pump for the Daedalus Astronautics @ASU hybrid rocket engine (HRE). The pump design was purposefully simplified due to time, fabrication, calculation, and capability constraints, which resulted in a lower fidelity design, with the option to be improved later. The impeller, shroud, volute, shaft, motor, and ESC were the main focuses of the pump assembly, but the seals, bearings, lubrication methods, and flow path connections were considered as elements which would require future attention. The resulting pump design is intended to be used on the Daedalus Astronautics HRE test cart for design verification. In the future, trade studies and more detailed analyses should and will be performed before this pump is integrated into the Daedalus Astronautics flight-ready HRE.

Description
Human habitation of other planets requires both cost-effective transportation and low time-of-flight for human passengers and critical supplies. The current methods for interplanetary orbital transfers, such as the Hohmann transfer, require either expensive, high fuel maneuvers or extended space travel. However, by utilizing the high velocities of a super-geosynchronous space elevator, spacecraft released from an apex anchor could achieve interplanetary transfers with minimal Delta V fuel and time of flight requirements. By using Lambert’s Problem and Free Release propagation to determine the minimal fuel transfer from a terrestrial space elevator to Mars under a variety of initial conditions and time-of-flight constraints, this paper demonstrates that the use of a space elevator release can address both needs by dramatically reducing the time-of-flight and the fuel budget.

Description
This thesis evaluates the viability of an original design for a cost-effective wheel-mounted dynamometer for road vehicles. The goal is to show whether or not a device that generates torque and horsepower curves by processing accelerometer data collected at the edge of a wheel can yield results that are comparable to results obtained using a conventional chassis dynamometer. Torque curves were generated via the experimental method under a variety of circumstances and also obtained professionally by a precision engine testing company. Metrics were created to measure the precision of the experimental device's ability to consistently generate torque curves and also to compare the similarity of these curves to the professionally obtained torque curves. The results revealed that although the test device does not quite provide the same level of precision as the professional chassis dynamometer, it does create torque curves that closely resemble the chassis dynamometer torque curves and exhibit a consistency between trials comparable to the professional results, even on rough road surfaces. The results suggest that the test device provides enough accuracy and precision to satisfy the needs of most consumers interested in measuring their vehicle's engine performance but probably lacks the level of accuracy and precision needed to appeal to professionals.

Description
This research project will test the structural properties of a 3D printed origami inspired structure and compare them with a standard honeycomb structure. The models have equal face areas, model heights, and overall volume but wall thicknesses will be different. Stress-deformation curves were developed from static loading testing. The area under these curves was used to calculate the toughness of the structures. These curves were analyzed to see which structures take more load and which deform more before fracture. Furthermore, graphs of the Stress-Strain plots were produced. Using 3-D printed parts in tough resin printed with a Stereolithography (SLA) printer, the origami inspired structure withstood a larger load, produced a larger toughness and deformed more before failure than the equivalent honeycomb structure.
