Historical study of Congo and Ghana during the period of decolonization with context of colonialism. The ideas of Neo-Colonialism and Pan-Africanism are explained and contrasted. Neo-Colonialism is a criticism of the coercive activities of former colonizing countries in former colonies. Pan-Africanism is the idea that all African people should be united to combat oppression and prejudice. These two forces directly clashed during decolonization with the United States playing the part of a Neo-Colonial power. The U.S., through organizations such as the C.I.A., attempted to destroy Pan-African ideas in both the Congo under Patrice Lumumba and Ghana under Kwame Nkrumah.

The goal of this project was to design and create a genetic construct that would allow for <br/>tumor growth to be induced in the center of the wing imaginal disc of Drosophila larvae, the <br/>R85E08 domain, using a heat shock. The resulting transgene would be combined with other <br/>transgenes in a single fly that would allow for simultaneous expression of the oncogene and, in <br/>the surrounding cells, other genes of interest. This system would help establish Drosophila as a <br/>more versatile and reliable model organism for cancer research. Furthermore, pilot studies were <br/>performed, using elements of the final proposed system, to determine if tumor growth is possible <br/>in the center of the disc, which oncogene produces the best results, and if oncogene expression <br/>induced later in development causes tumor growth. Three different candidate genes were <br/>investigated: RasV12, PvrACT, and Avli.

Microfluidic devices represent a growing technology in the world of analytical chemistry. Serial femtosecond crystallography (SFX) utilizes microfluidic devices to generate droplets of an aqueous buffer containing protein crystals, which are then fired out as a jet in the beam of an X-ray free electron laser (XFEL). A crucial part of the device is its method of droplet detection. This project presents a design for a capacitive sensor that uses a unique electrode configuration to detect the difference in capacitance between the aqueous and oil phases. This design was developed using MATLAB and COMSOL Multiphysics simulations and printed using high-resolution 3D printing. Results show that this design can successfully distinguish between the two immiscible liquids, confirming it as a possible detection method in future SFX experiments.

During the COVID-19 pandemic, increased burdens have been placed on the Arizona healthcare system, and its healthcare providers. Using a survey with a sample of N=308 prescribing providers and nurses in the Arizona healthcare system, the impact of COVID-19 on the wellbeing of healthcare providers was assessed. The survey used measures to evaluate for physical and emotional wellbeing, burnout, stressors associated with COVID-19, and work-life experiences, and found an overall negative impact on the wellbeing of healthcare workers during the COVID-19 pandemic with increased levels of reported stress and tiredness, concern for the health of family and loved ones, concern for the hardships of patients, lack of alignment between organizational priorities and personal values, and low levels of support and appreciation from socially and from leadership at work.

The 1980 Winter Olympic semi-final hockey game between the United States and Soviet Union changed the history of sporting events. The outcome took everyone by surprise, and it reinvigorated patriotism in the United States. It was and forever will be known as a miracle. The hockey game has only grown in popularity due to movies, books, and articles reminiscing on one of the greatest sports upsets in history. The United States-Russia rivalry has been a strong one since the very beginning of sports. The United States has always tried to keep up with the Russian talent, but in 1980 they took the Soviets by surprise, at height of the cold war. Not only were they rivals in sports, but enemies at a profound political level. Over the years, the tensions between the two countries have diminished, but recently they have increased again. Although these tensions continue to rise, these countries are able to battle for the top seed through sports. This has been shown throughout the years with one of the main competitions being the 1980 Winter Olympics semi-final hockey game.

The purpose of this study is to create and establish an efficient and cost-effective solution to decrease the effects of sedentarism in pregnant women. Our team was given a propelling question, from which we had to narrow down our scope and conduct primary and secondary research to determine our ideal customers. The design of our study intends to imitate the development of a startup where ideas are created from scratch and the final deliverable is a business model plan that shows some sort of traction. Our first major finding is that a sedentary lifestyle can be treated without major challenges in low risk pregnancies. We determined that uncertainty and lack of concise and clear information is one of the main causes of an increased level of sedentary behavior in low risk pregnancies. A significant driver for women to do some sort of activity or exercise stems from feeling supported, which doesn’t necessarily come from their partner or couple, but instead from other women that are going through a similar process as them. There are apps in the market that intend to serve pregnant women; however, there is not one that incorporates a social aspect to achieve their goal. In conclusion, there is opportunity in the market for a socially integrated pregnancy fitness app. The Gleam concept has been consciously developed to decrease sedentary behavior through concise, clear, and reliable information and by encouraging women through a socialization platform.

The colossal global counterfeit market and advances in cryptography including quantum computing supremacy have led the drive for a class of anti-counterfeit tags that are physically unclonable. Dendrites, previously considered an undesirable side effect of battery operation, have promise as an extremely versatile version of such tags, with their fundamental nature ensuring that no two dendrites are alike and that they can be read at multiple magnification scales. In this work, we first pursue a simulation for electrochemical dendrites that elucidates fundamental information about their growth mechanism. We then translate these results into physical dendrites and demonstrate methods of producing a hash from these dendrites that is damage-tolerant for real-world verification. Finally, we explore theoretical curiosities that arise from the fractal nature of dendrites. We find that uniquely ramified dendrites, which rely on lower ion mobility and conductive deposition, are particularly amenable to wavelet hashing, and demonstrate that these dendrites have strong commercial potential for securing supply chains at the highest level while maintaining a low price point.

Fluoroquinolone antibiotics have been known to cause severe, multisystem adverse side effects, termed fluoroquinolone toxicity (FQT). This toxicity syndrome can present with adverse effects that vary from individual to individual, including effects on the musculoskeletal and nervous systems, among others. The mechanism behind FQT in mammals is not known, although various possibilities have been investigated. Among the hypothesized FQT mechanisms, those that could potentially explain multisystem toxicity include off-target mammalian topoisomerase interactions, increased production of reactive oxygen species, oxidative stress, and oxidative damage, as well as metal chelating properties of FQs. This review presents relevant information on fluoroquinolone antibiotics and FQT and explores the mechanisms that have been proposed. A fluoroquinolone-induced increase in reactive oxygen species and subsequent oxidative stress and damage presents the strongest evidence to explain this multisystem toxicity syndrome. Understanding the mechanism of FQT in mammals is important to aid in the prevention and treatment of this condition.

A growing body of research suggests a link between adverse childhood experiences and negative health outcomes. However, less is known about where racial discrimination ranks compared to other adverse childhood experiences, such as maltreatment. To address this issue, I conducted two systematic reviews of meta-analyses to compare the magnitudes of the links between racial discrimination and depressive symptoms and childhood maltreatment and depressive symptoms. My aim was to establish if racial discrimination should be considered an adverse childhood experience. My results demonstrated that the link between racial discrimination and depressive symptoms (r = 0.27) is comparable to the links between 4 different manifestations of maltreatment and depressive symptoms (physical abuse: r = 0.257, emotional abuse: r = 0.301, neglect: r = 0.381, sexual abuse: r = 0.408). I discuss the implications of these findings and propose future research directions.
