Before the COVID-19 pandemic, there was a great need for United States’ restaurants to “go green” due to consumers’ habits of frequently eating out. Unfortunately, COVID-19 has caused this initiative to lose traction. While the amount of customers ordering takeout has increased, there is less emphasis on sustainability.<br/>Plastic is known for its harmful effects on the environment and the extreme length of time it takes to decompose. According to the International Union for Conservation of Nature (IUCN), almost 8 million tons of plastic end up in the oceans at an annual rate, threatening not only the safety of marine species but also human health. Modern food packaging materials have included a blend of synthetic ingredients, trickling into our daily lives and polluting the air, water, and land. Single-use plastic items slowly degrade into microplastics and can take up to hundreds of years to biodegrade.<br/>Due to COVID-19, restaurants have switched to takeout and delivery options to adapt to the new business environment and guidelines enforced by the Center of Disease Control (CDC) mandated guidelines. Some of these guidelines include: notices encouraging social distancing and mask-wearing, mandated masks for employees, and easy access to sanitary supplies. This cultural shift is motivating restaurants to search for a quick, cheap, and easy fix to adapt to the increased demand of take-out and delivery methods. This increases their plastic consumption of items such as plastic bags/paper bags, styrofoam containers, and beverage cups. Plastic is the most popular takeout material because of its price and durability as well as allowing for limited contamination and easy disposability.<br/>Almost all food products come in packaging and this, more often than not, is single-use. Food is the largest market out of all the packaging industry, maintaining roughly two-thirds of material going to food. The US Environmental Protection Agency reports that almost half of all municipal solid waste is made up of food and food packaging materials. In 2014, over 162 million tons of packaging material waste was generated in the states. This typically contains toxic inks and dyes that leach into groundwater and soil. When degrading, pieces of plastic absorb toxins like PCBs and pesticides, and then each piece will, in turn, release toxic chemicals like Bisphenol-A. Even before being thrown away, it causes negative effects for the environment. The creation of packaging materials uses many resources such as petroleum and chemicals and then releases toxic byproducts. Such byproducts include sludge containing contaminants, greenhouse gases, and heavy metal and particulate matter emissions. Unlike many other industries, plastic manufacturing has actually increased production. Demand has increased and especially in the food industry to keep things sanitary. This increase in production is reflective of the increase in waste. <br/>Although restaurants have implemented their own sustainable initiatives to combat their carbon footprint, the pandemic has unfortunately forced restaurants to digress. For example, Just Salad, a fast-food restaurant chain, incentivized customers with discounted meals to use reusable bowls which saved over 75,000 pounds of plastic per year. However, when the pandemic hit, the company halted the program to pivot towards takeout and delivery. This effect is apparent on an international scale. Singapore was in lock-down for eight weeks and during that time, 1,470 tons of takeout and food delivery plastic waste was thrown out. In addition, the Hong Kong environmental group Greeners Action surveyed 2,000 people in April and the results showed that people are ordering out twice as much as last year, doubling the use of plastic.<br/>However, is this surge of plastic usage necessary in the food industry or are there methods that can be used to reduce the amount of waste production? The COVID-19 pandemic caused a fracture in the food system’s supply chain, involving food, factory, and farm. This thesis will strive to tackle such topics by analyzing the supply chains of the food industry and identify areas for sustainable opportunities. These recommendations will help to identify areas for green improvement.

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.

This study utilized a literature review and an analysis of Google Trends and Google News data in order to investigate the coverage that American men’s soccer gets from the media compared to that given to other major American sports. The literature review called upon a variety of peer-reviewed, scholarly entries, as well as journalistic articles and stories, to holistically argue that soccer receives short-sighted coverage from the American media. This section discusses topics such as import substitution, stardom, and American exceptionalism. The Google analysis consisted of 30 specific comparisons in which one American soccer player was compared to another athlete playing in one of America’s major sports leagues. These comparisons allowed for concrete measurements in the difference in popularity and coverage between soccer players and their counterparts. Overall, both the literature review and Google analysis yielded firm and significant evidence that the American media’s coverage of soccer is lopsided, and that they do play a role in the sport’s difficulty to become popular in the American mainstream.

Supply chain management is becoming an increasingly vital component in the success of an organization. Business and government leaders continue to recognize the importance of having robust and resilient supply chains. This trend has been accelerated by the COVID-19 pandemic which brought to light the fragility of the modern global supply chain network. Decades of offshoring has led to the inability of businesses to adequately manufacture critical supplies in times of crisis. This reality is most prevalent in the healthcare industry. Antibiotics, pharmaceuticals, PPE, testing equipment are almost entirely sourced from Chinese manufacturers. Building a more resilient healthcare supply chain requires a revaluation of critical items, cooperation between businesses and government, and recognizing the precarious situation for the United States which has become completely reliant on foreign manufacturers. <br/> Businesses are looking to develop more resilient supply chains which can respond and predict unforeseen market circumstances. The federal government is reckoning the national security concern of sourcing nearly all antibiotics, and pharmaceuticals from Chinese manufacturers. Aligning the goals of key stakeholders and developing the necessary incentive structure to encourage domestic manufacturing is necessary to respond to this crisis. As the global economy becomes increasingly interconnected and dependent on changes to markets anywhere on the globe, a renewed focus on proactive strategies is necessary to ensure the security and resiliency of the United States healthcare supply chain.

The objective of this experiment was to investigate the correlation between the starting pitch angle of a Dragon Boat paddle and the ensuing total stress and force on the paddle during the first stroke. During the first stroke (i.e., starting at rest) the stress on the paddle can be equated with the force output. To do this, a paddle was modified with a strain gauge and other equipment, and tests were run varying the pitch angle. The results showed that while the most positive starting angle yielded the highest stress and force on the paddle, there was no discernible trend correlating the angle to the stress. Further experimentation must be run to determine which other factors influence the stress.

This study aims to showcase the results of a quadrotor model and the mathematical techniques used to arrive at the proposed design. Multicopters have made an explosive appearance in recent years by the controls engineering community because of their unique flight performance capabilities and potential for autonomy. The ultimate goal of this research is to design a robust control system that guides and tracks the quadrotor's trajectory, while responding to outside disturbances and obstacles that will realistically be encountered during flight. The first step is to accurately identify the physical system and attempt to replicate its behavior with a simulation that mimics the system's dynamics. This becomes quite a complex problem in itself because many realistic systems do not abide by simple, linear mathematical models, but rather nonlinear equations that are difficult to predict and are often numerically unstable. This paper explores the equations and assumptions used to create a model that attempts to match roll and pitch data collected from multiple test flights. This is done primarily in the frequency domain to match natural frequency locations, which can then be manipulated judiciously by altering certain parameters.

The thesis is an investigation on current regulations of commercial aircraft landing and take-off procedures and an analysis of potential weaknesses within the regulatory system for commercial aerospace. To determine such flaws, an area of worse-case scenarios with regard to the aforementioned flight operations was researched. The events selected to best-depict these scenarios where incidents of aircraft overrunning the runway, referred to as runway excursions. A case-study conducted of 44 federal investigations of runway excursions produced data indicating four influential factors within these incidents: weather, pilot error, instrument malfunction, and runway condition. Upon examination, all but pilot error appeared to have federal enforcement to diminish the occurrence of future incidents. This is a direct result of the broad possibilities that make up this factor. The study then searched for a consistent fault within the incidents with the results indicating an indirect relationship of thrust reversers, a technique utilized by pilots to provide additional braking, to these excursions. In cases of thrust reverser failure, pilots' over-reliance on the system lead to time being lost from the confusion produced by the malfunction, ultimately resulting in several different runway excursions. The legal implication with the situation is that current regulations are ambiguous on the subject of thrust reversers and thus do not properly model the usage of the technique. Thus, to observe the scope of danger this ambiguity presents to the industry, the relationship of the technique to commercial aerospace needed to be determined. Interviews were set-up with former commercial pilots to gather data related to the flight crew perspective. This data indicated that thrust reversers were actively utilized by pilots within the industry for landing operations. The problem with the current regulations was revealed that the lack of details on thrust reverser reflected a failure of regulations to model current industry flight operations. To improve safety within the industry, new data related to thrust reverser deployment must be developed and enforced to determine appropriate windows to utilize the technique, thus decreasing time lost in confusion that results from thrust reversers malfunction. Future work would be based on producing simulations to determine said data as well as proposing the policy suggestions produced by this thesis.
