Optimization of Cathodes in Microbial Fuel Cells for the Production of Electrical Energy
No full textabstract: Optimizing cathodes for microbial fuel cells is important to maximize energy harvested from wastewater. Cathodes were made by modifying a recipe from previous literature and testing the current of the cathode using linear sweep voltammetry. The cathodes contained an Fe-N-C catalyst combined with a Polytetrafluoroethylene binder. Optimizing the power resulting from the microbial fuel cells will help MFCs be an alternative energy source to fossil fuels. The new cathodes did improve in current production from −16 / to −37 / at -0.4 V. When fitted using a Butler-Volmer model, the cathode linear-sweep voltammograms did not follow the expected exponential trend. These results show a need for more research on the cathodes and the Butler-Volmer model, and they also show that the cathode is ready for further and longer application in a microbial fuel cell
Quantifying Pressure Metrics from the Appropriate Utilization of a Pelvic Circumferential Compression Device
No full textabstract: The purpose of this study is to collect baseline internal and external pressure data for the three most commonly used pelvic circumferential compression devices (PCCD). Unstable pelvic fractures as a result of automobile accidents, falls, and other traumatic injuries mortality rate [3]. Early use of pelvic circumferential compression devices can mitigate fatal outcomes [4]-[5]. Prolonged eternal pressure above 9.3kPa can result in long-term soft tissue damage and pressure ulcers [7]. This study hypothesizes that the application of the three most commonly used PCCDs would result in the same mean maximum point pressure exertion. To study this, internal and external, both analog and digital, pressure apparati were used to collect data. The results of this data collection demonstrate a discrepancy in the pressure distribution between right and left greater trochanters within each PCCD. Additionally, the results suggest there is an effect of internal packing on the pressure exertion externally at the two greater trochanters within each PCCD. Lastly, the differences in pressure exertion between each PCCD, internally and externally, were inconclusive as some compared metrics resulted in statistically significant results while others did not. The methodologies employed in this study can be improved through fixation of pressure collection instruments, utilization of digital pressure mats, and removal of confounding factors. The results of this study indicate that digitized, discrete data over a fixed time interval may be clinically useful, suggesting that a digital data collection would yield more reliable data. Additionally, internally mounted pressure sensor data will provide more precise results than the analog method employed herein, as well as provide insight towards bone reduction and displacement following the application of PCCDs. Finally, the information gathered from this study can be utilized to improve upon existing technologies to create a more innovative solution. (abstract
Selling Profit and Purpose: Analyzing the Reality and Feasibility of Base of the Pyramid Strategy (BoP) thorough an Examination of BoP Iterations and Business Cases
No full textabstract: Base of the pyramid (BoP) theory was posited in 2002, as a revolutionary method to combine profit and purpose. In this paper the concept of BoP is explored by delving into the development of the idea. Understanding the successes and failures of each iteration provides the opportunity to coalesce the efficacy of BoP. This leads into a dissemination of elements of successful BoP implementations. These elements establish concepts that are vital to any semblance of BoP success. Case studies then develop the complexity and nuance of BoP implementation; establishing there is no cookie-cutter formula for success. Ultimately, base of the pyramid emerges as a much more deeply complicated concept than originally suggested. Despite the ambiguity of BoP, the theory continues to be one of the most viable opportunities for correcting the inequalities of the world. (abstract
Perceived Stigma in Interracial/Interethnic Couples and their Family Relationships
No full textabstract: The research study that I conducted is on perceived stigma in interracial/interethnic couples and its impact on family relationships. With the growing number of interracial/interethnic couples in the United States and the current climate regarding racism in United States, I am interested in examining how the stigma that interracial couples face impacts their relationship satisfaction and quality, as well as their relationship with family members. The study examines perceived stigma both internalized and experienced among individuals who have felt racially discriminated because of their interracial relationship by their family and their partner's family. Thus, the current study focused on whether perceived stigma in interracial couples impacts their family relationships which ultimately is associated with their relationship satisfaction. (abstract
Jews & Tattoos
No full textabstract: The main reason behind this video recorded interview is to understand what today’s Jewish population believes about tattoos. There are many different rumors that are believed to be true by a larger portion of the Jewish population. This project will choose to focus on an array of different members of the Jewish community, and their differing opinions when it comes to tattoos. This documentary video will discuss the different aspects of who is “allowed� to get a tattoo, what the burial myth is, why it exists in the first place, etc. The people interviewed will range from Rabbi’s to Jewish kids in college. The reason why this project is being created is in order to better understand one religions viewpoint on body modification and what this means for future generations to come. Will also at one point discuss what the project meant to me personally, and also the implications of COVID-19. The video recorded interview will help to uncover opinions, and beliefs of Jewish people alive today. (abstract

Vaccine Essentials: How They Came To Be, Why They Are Necessary, and Why Vaccine Hesitancy Exists
No full textabstract: Vaccines are modern medicine’s best way of combating the majority of viral and bacterial illnesses and contagions to date. Thanks to the introduction of vaccines since the first uses of them in 1796 (Jenner’s smallpox vaccine), they have drastically reduced figures of disease worldwide, turning once lethal and life changing conditions into minor annoyances; Some of these afflictions have even become nonexistent or even extinct in certain parts of the world outside of a controlled laboratory setting. With many advancements and overwhelming evidence proving their efficiency, it is clear that vaccines have become nothing less than a necessity for everyday healthcare in today’s world.
The greatest contributor to the creation and evolution of vaccines throughout the years is by far the progress and work done in the field of molecular and cellular biology. These advancements have become the bedrock of modern vaccination, as shown by the differing types of vaccines and their methodology. The most common varieties of vaccines are include ‘dead’ or inactivated vaccines, one such example being the pertussis strain of vaccines, which have either dead or torn apart cells for the body to easily fight off, allowing the immune system to easily and quickly counter the illness; Additionally, there are also live attenuated vaccines (LAVs) in which a weaker version of the pathogen is introduced to the body to stimulate an immune response, or a recombinant mRNA vaccine where mRNA containing the coding for an antigen is presented for immunological response, the latter being what the current COVID-19 vaccines are based on. This is in part aided by the presence of immunological adjuvants, antigens and substances that the immune system can recognize, target, and remember for future infections. However, for more serious illnesses the body needs a bigger threat to analyze, which leads to live vaccines- instead of dead or individual components of a potential pathogen, a weakened version is created in the lab to allow the body to combat it. The idea behind this is the same, but to a larger degree so a more serious illness such as measles, mumps, and rubella (MMR) do not infect us.
However, for the past couple of decades the public’s views on vaccination has greatly varied, with the rise of fear and disinformation leading those to believe that modern medicine is a threat in disguise. The largest of these arguments began in the late 90’s, when Dr. Andrew Wakefield published an article under the Lancet with false information connecting vaccinations to the occurrence of autism in younger children- a theory which has since then been proven incorrect numerous times over. Unfortunately, the rise of hysteria and paranoia in people, along with more misinformation from misleading sources, have strengthened the anti-vaccination cause and has made it into a serious threat to the health of those world-wide.
The aim of this thesis is to provide an accurate and thorough analysis on these three themes- the history of vaccines, their inner workings and machinations in providing immune defenses for the body, and the current controversy of the anti-vaccination movement. Additionally, there will be two other sections going in-depth on two specific areas where vaccination is highly important; The spread and fear of the Human Immunodeficiency Virus (HIV) has been around for nearly four decades, so it begs the question: what makes this such a difficult virus, and how can a vaccine be created to combat it? Additionally, in the last year the world has encountered a new virus that has evolved into a global pandemic, SARS-COV 2. This new strain of coronavirus has shown itself to be highly contagious and rapidly mutating, and the race to quickly develop a vaccine to counteract it has been on-going since its first major infections in Wuhan, China. Overall, this thesis will go in-depth in providing the most accurate, up-to-date, and critical information regarding vaccinations today. (abstract
