Description
Production from a high pressure gas well at a high production-rate encounters the risk of operating near the choking condition for a compressible flow in porous media. The unbounded gas pressure gradient near the point of choking, which is located near the wellbore, generates an effective tensile stress on the porous rock frame. This tensile stress almost always exceeds the tensile strength of the rock and it causes a tensile failure of the rock, leading to wellbore instability. In a porous rock, not all pores are choked at the same flow rate, and when just one pore is choked, the flow through the entire porous medium should be considered choked as the gas pressure gradient at the point of choking becomes singular. This thesis investigates the choking condition for compressible gas flow in a single microscopic pore. Quasi-one-dimensional analysis and axisymmetric numerical simulations of compressible gas flow in a pore scale varicose tube with a number of bumps are carried out, and the local Mach number and pressure along the tube are computed for the flow near choking condition. The effects of tube length, inlet-to-outlet pressure ratio, the number of bumps and the amplitude of the bumps on the choking condition are obtained. These critical values provide guidance for avoiding the choking condition in practice.

Description
Tesla turbo-machinery offers a robust, easily manufactured, extremely versatile prime mover with inherent capabilities making it perhaps the best, if not the only, solution for certain niche applications. The goal of this thesis is not to optimize the performance of the Tesla turbine, but to compare its performance with various working fluids. Theoretical and experimental analyses of a turbine-generator assembly utilizing compressed air, saturated steam and water as the working fluids were performed and are presented in this work. A brief background and explanation of the technology is provided along with potential applications. A theoretical thermodynamic analysis is outlined, resulting in turbine and rotor efficiencies, power outputs and Reynolds numbers calculated for the turbine for various combinations of working fluids and inlet nozzles. The results indicate the turbine is capable of achieving a turbine efficiency of 31.17 ± 3.61% and an estimated rotor efficiency 95 ± 9.32%. These efficiencies are promising considering the numerous losses still present in the current design. Calculation of the Reynolds number provided some capability to determine the flow behavior and how that behavior impacts the performance and efficiency of the Tesla turbine. It was determined that turbulence in the flow is essential to achieving high power outputs and high efficiency. Although the efficiency, after peaking, begins to slightly taper off as the flow becomes increasingly turbulent, the power output maintains a steady linear increase.

Ever since Cleveland-based disc jockey Alan Freed coined the term "rock 'n' roll" in the early 1950s, the genre has gone through various mass media and digital changes over the decades. These changes took place on the radio, television and internet. Each platform had its own unique ways of increasing the popularity of rock artists as well as the genre itself. Although the radio is not as popular today as it was in the 20th century, it helped pave the way for today’s most popular music streaming platforms like Spotify and Apple Music. The television gave artists a chance to be seen nationally or even worldwide. Music videos and live performances allowed viewers to see past artists’ voices and witness their energy. The internet gave bands and artists multiple platforms to share their content and connect with fans. In 2020, having a social media presence became essential for artists wanting to maintain a successful music career during the COVID-19 pandemic. Rock music most likely would not be what it is today if it had not gone through these various changes.

When you think of actors, you probably think of the glitz and glam of Hollywood. It is a career many desire to have because of this initial perception. Who does not want to live the lavish life of an actor? Who does not want to get paid to basically play dress up? The truth is acting is much more, and less, than that. In fact, there are almost no two actors with the same exact journey to where they are. The career itself is very subjective, which is quite the scary thought to many including myself. Since I was a kid, acting is all I wanted to do. However, I have also always been someone who enjoys stability and consistent next steps, which is why I have been terrified at the idea of pursuing acting for so long. It is not a career that guarantees success. It is not even a career that has one definition of success. What is not shown behind the flashing lights and the glamour is what it truly takes to “make it”. Like I said, there are different variations of “making it” as well. Because of this idea that a career in acting is not all one thing, I wanted to find the commonalities. Are there things anyone who wants to be an actor, whether it is theater, film, television, or commercial acting, can do to increase their chances for success? What are the steps necessary to be taken seriously in this industry? In this thesis, I am going to explore the intricacies of this career to try to answer these questions.

Description
Our thesis project, blanknationalpark.com, asked one question : how is climate change impacting National Parks in America? We decided to travel to three different areas: Joshua Tree, Glacier and Everglades National Park. It didn’t take long to discover that there was never a definitive answer. The effects of climate change looked different in every park we visited. Joshua Tree was struggling with changes in temperature, climate regime and an increase in fires. The U.S Geological Survey predicted that all of the glaciers in Glacier National Park could be gone by 2030. Everglades National Park was facing the constant threat of sea-level rise, invasive species and stronger hurricanes. However, in every park, one thing was certain - they all would not have their iconic features in the future due to climate change. For our thesis, we created blanknationalpark.com to emphasize the fact that Joshua Tree National Park won’t have Joshua Trees in the coming centuries, glaciers would cease to exist in Glacier National Park and the entire Everglades ecosystem itself will be underwater in the next century and a half. Thus, our project name, “Blank National Park”, pays tribute to the uncertainty of what these famous landscapes could look like in the future. Our main goal was to provide the public with a visual experience that is not only informative but engaging so that we could provide an educational experience about a critical situation without appearing too dismal. We chose to include our last page, ‘Solutions’, to establish hope for the future, and encourage people to take action to help preserve National Parks and the world we live in.

Ice hockey is a minority sport in New Zealand, but many people are dedicating their lives to grow its popularity in the country. Hockey in Kiwi Land: Exploring the Ice Hockey Culture of New Zealand presents the voices of those involved in the country’s largest city, Auckland, and their efforts in the country’s highest league. The New Zealand Ice Hockey League is made up of people of different backgrounds, including fathers, teenagers, university students, full-time workers, and Canadians. Information on ice hockey’s culture was found through spending a week in Auckland and interviewing different people involved with the West Auckland Admirals, the defending champion at the time. The information was then created into a website that displays both a written and visual component. The photo stories were made to capture the physical aspect of a game that wants to dominate in a country obsessed with rugby. The interviews capture why those born in New Zealand love ice hockey and what needs to change to promote the sport better. Many in the league came from ice hockey haven Canada, and they provided insight on the differences they noticed between New Zealand and North America. The project taught me more about New Zealand’s ice hockey programs and how they differ from those in North America. The interviews showed that while the sport will be a minority in the country for the next few years, it will continue to grow through the joint efforts of international and New Zealand-born players giving back.

As a student at Arizona State University’s Walter Cronkite School of Journalism and Barrett, The Honors College, as well as a lover of travel, Brielle Ashford decided to combine her passions and spent four months abroad in Spring, 2019, creating a senior thesis in digital international journalism. She enrolled in the Center for Intercultural Educational Exchange's Open Campus program for a semester and spent a month and a half each in three countries. Starting in Cape Town, South Africa, she interviewed locals about their lives post-Apartheid. In Paris, France, Brielle found a story in a non-profit that teaches French youth about religious diversity. Lastly in Rome, Italy, she covered the famous, vibrant food culture of gelato at the city’s oldest gelateria. It was the experience of a lifetime and the stories stand on their own... and she made it all happen with little more than the Adobe editing suite and an iPhone X.

The definition of a service animal is often misunderstood by the public. This makes life more difficult for individuals with disabilities who rely on service animals to function and navigate through society.
“Arizona Service Animals” is a creative project in the form of a website
( ArizonaServiceAnimals.com ) designed to provide the public with information,
resources, and true stories about service animals in the state of Arizona.
The site covers the different types of support animals, the training process, the legal rights of service animal handlers and businesses, and Arizona’s new law regarding fake service animals.
It also includes the stories of real service animal handlers and trainers who share their experiences and explain what they would like the public to know.
This paper provides context into the history of dogs and service dogs, as well as
information on the three types of support animals. It also includes the methodology of the project.
