Exploration of Intercontinental Rocket Travel Using the Commercialization of the Airline industry
No full textabstract: Long distance travel around the globe can potentially be revolutionized with the use of an intercontinental rocket that uses low earth orbit as its medium. This transport system can increase growth in many new businesses like tourism travel between the continents. This research evaluates the technical and non-technical possibilities of using a double-stage reusable rocket, where the second stage is also a reusable, rocket-powered passenger vehicle using a low earth orbit space journey with a stabilized re-entry method that ensures passenger comfortability. A potential network of spaceports spanning the globe is postulated within a range of 4,000 km to 8,000 km(2,160 nm to 4,320 nm) of each other, and each located within an hour by any other means of ground transport to population hubs greater than four million. This will help further connect the world as the journey from one major city to another would take at most an hour, and no point on the habited continents would be more than 4,000 km(2,160 nm) from a spaceport. It is assumed that the costs of an international first class flight ticket are in the thousands of dollars range showing how there is a potential market for this type of travel network. The reasoning and analysis, through a literature review, for an intercontinental rocket vehicle is presented along with the various aspects of the possibility of this kind of travel network coming to fruition in the near future.

Casting Clausewitz: Revising On War’s Combat Equation
No full textabstract: In the preface to On War, Clausewitz describes his work as a series of loosely connected pure nuggets of knowledge. He then states his hope that his nuggets would eventually be connected and consolidated into what he calls a “final casting without dross�. It is the goal of this work to begin that consolidation and take steps towards a final casting and a more comprehensive understanding of war, combining Clausewitz’s models with modern findings not available at the time of On War’s conception. Using Clausewitz’s combat equation as a foundation for a framework on the nature of war, this work will synthesize many of On War’s central concepts, while also expanding upon the terms and mechanics presented in Book One. It is hoped that the resulting model will combine the best of Clausewitz’s findings in a way that makes the sum of the parts greater than the whole, and allows previous findings which were isolated to a particular silo of study to be cross examined for exponential application to the study of war. This may in due time, with additional contributions, result in the ever desired revolution in military affairs and enhance the military sciences for years to come. (abstract
Inclusion of African American Pregnant Women in Preeclampsia Research Studies
No full textabstract: Preeclampsia is a disease that occurs during pregnancy and affects upwards of 10% of pregnancies around the world (Osungbade & Ige, 2011). African American pregnant women are particularly vulnerable and die at a disproportionate rate compared to other races. In this literature review, three research studies were analyzed to determine if African American pregnant women were included in preeclampsia Studies. Only one of the studies included in this review met all criteria by including African American pregnant women. One research study met half of the criteria; however, the authors noted that there was not enough evidence for Black Americans. The third research article also only met half of the criteria. We conclude that further studies are needed that include African American women in studies on preeclampsia. (abstract

The Architect as a Civic Practitioner: Reimagined Approaches for the Architecture Field to Advance Equitable Practice
No full textabstract: This thesis asks the question, 'How can equitable approaches be advanced within the architectural discipline in order for architects to make increasingly meaningful social and civic impacts on vulnerable communities?' It is a product of my experience working on a project for a low-income community of color, along with my realization that I did not possess the tools to be able to design in a way that fostered equity for this community. In an attempt to design those tools for myself and question how architectural practices can be used to enhance equity in one's work, the thesis features the reimagining of several architectural approaches. The approaches take inspiration from the discipline of equitable creative placemaking, drawing from concepts such as cultural asset mapping, co-creation, and fostering community agency. (abstract
Power in Memory: A study of American history and oral tradition in the Arizona Territory
No full textabstract: The history of Arizona is filled with ambitious pioneers, courageous Natives, and loyal soldiers, but there is a seeming disconnect between those who came before us and many of those who currently inhabit this space. Many historic locations that are vital to discovering the past in Arizona are both hard to find and lacking in information pertaining to what happened there. However, despite the apparent lack of history and knowledge pertaining to these locations, they are vitally present in the public memory of the region, and we wish to shed some much-needed light on a few of these locations and the historical takeaways that can be gleaned from their study. This thesis argues the significance of three concepts: place-making, public memory, and stories. Place-making is the reinvention of history in the theater of mind which creates a plausible reality of the past through what is known in the present. Public memory is a way to explain how events in a location affect the public consciousness regarding that site and further events that stem from it. Lastly, stories about a place and event help to explain its overall impact and what can be learned from the occurrences there. Throughout this thesis we will be discussing seven sites across Arizona, the events that occurred there, and how these three aspects of study can be used to experience history in a personal way that gives us a special perspective on the land around us. The importance of personalizing history lies in finding our own identity as inhabitants of this land we call home and knowing the stories gives us greater attachment to the larger narrative of humanity as it has existed in this space.

Numerical Modeling of Hydrodynamic Flow Focusing in a Microfluidic Device for Time-Resolved Serial Crystallography
No full textabstract: Serial femtosecond crystallography (SFX) with an X-ray free-electron laser (XFEL) has enabled the determination of protein structures and protein reaction intermediates in millisecond to microsecond time resolutions. Mix-and-Inject crystallography (MISC) at XFELs enables fast mixing in the magnitude of milliseconds in order to achieve desired reaction time points. For these experiments, numerical simulations of a hydrodynamic flow mixer capable of fast mixing by diffusion has been developed using both COMSOL Multiphysics 5.6 and QuickerSims Computational Fluid Dynamics (CFD) Toolbox for MATLAB. These simulation programs were compared by calculations of mixing times and concentration flow profiles. Mixing times in the range of 1-10 ms were calculated in COMSOL under certain flow rate conditions whereas mixing times in the range of 6-15 ms were calculated with QuickerSims. From these mixing times, reaction intermediates can be varied from sub-millisecond to several hundred millisecond time points for a MISC experiment. Explanations for the discrepancies between the two models were attributed to variations in parameter definitions and meshing. Further analysis on the mixing characteristics were investigated by calculating an analytical solution to the convection-diffusion equation for fluid flow in a two-dimensional rectangular channel. The concentration profile along the width of the channel for the analytical solution was compared with the numerical solution obtained with COMSOL and QuickerSims. Upon comparison, it was determined that the diffusion coefficient may not be a significant factor for the disagreement between the two hydrodynamic flow models. (abstract

The Effect of Transcranial Alternating Current Stimulation on Speech Motor Learning
No full textabstract: Speech motor learning is important for learning to speak during childhood and maintaining the speech system throughout adulthood. Motor and auditory cortical regions play crucial roles in speech motor learning. This experiment aimed to use transcranial alternating current stimulation, a neurostimulation technique, to influence auditory and motor cortical activity. In this study, we used an auditory-motor adaptation task as an experimental model of speech motor learning. Subjects repeated words while receiving formant shifts, which made the subjects’ speech sound different from their production. During the adaptation task, subjects received Beta (20 Hz), Alpha (10 Hz), or Sham stimulation. We applied the stimulation to the ventral motor cortex that is involved in planning speech movements. We found that the stimulation did not influence the magnitude of adaptation. We suggest that some limitations of the study may have contributed to the negative results. (abstract
