Description
Orbiting space debris is an active issue that affects the capability of space launch for future satellites, probes, and space shuttles, and it will become a nearly insurmountable problem without action. Debris of varying sizes and speeds orbit the Earth at a range of heights above the atmosphere and need to be removed to avoid damage to crucial equipment of active orbiting satellites including the International Space Station. Finding a feasible solution to space debris removal requires that several facets be covered to become a reality; these include being aware of the problem in magnitude and source. This literature assessment covers the magnitude of space debris in low-earth and geosynchronous orbit as well as collision events which have increased the amount of space debris. There have been efforts made by several space agencies to control the amount of space debris added to orbit by current and future launches over the last decade \u2014 serving as a temporary fix before removal can be executed. This paper explores known removal efforts through mitigation, projects conceived and tested by DARPA, related space policies and laws, CubeSat technology, and the cataloguing of known space debris. To make space debris removal a reality, roadblocks need to be removed to acquire permission from states or countries for space missions. For example, these restrictions are in place to protect the assets of several countries and organizations. Guidelines set to curb the growth of space debris fail to prevent the growth due to the restrictions for ownership rights making them not as effective. This paper covers space policy and laws, the economy, satellite ownership, international conflict, status of space debris, and the overall feasibility of space debris removal. It will then discuss currently proposed solutions for the removal of space debris. Finally, this paper attempts to weight the advantages and disadvantages of the idea that space debris removal should include the opportunity to recycle materials. For example, defunct satellites and other discarded space crafts could be used for future launches. It will conclude with a personal exploration of what materials can be recycled, what chemical processes can be used to break down materials, and how to combine recycling and chemical processes for space-based recycling stations between Earth and the moon. The overall question that drives the search for making space debris removal a reality is whether it is feasible in multiple areas including technologically, legally, monetarily, and physically.

Description
Brown adipose tissue (BAT) is thought to be important in combating obesity as it can expend energy in the form of heat, e.g. thermogenesis. The goal of this study was to study the effect of injected norepinephrine (NE) on the activation of BAT in rats that were fed a high fat diet (HFD). A dose of 0.25 mg/kg NE was used to elicit a temperature response that was measured using transponders inserted subcutaneously over the BAT and lower back and intraperitoneally to measure the core temperature. The results found that the thermic effect of the BAT increased after the transition from low fat diet to a high fat diet (LFD) yet, after prolonged exposure to the HFD, the effects resembled levels found with the LFD. This suggests that while a HFD may stimulate the effect of BAT, long term exposure may have adverse effects on BAT activity. This may be due to internal factors that will need to be examined further.

Description
Cystic Fibrosis (CF) is a genetic disorder that disrupts the hydration of mucous of the lungs, which promotes opportunistic bacterial infections that begin in the affected person’s childhood, and persist into adulthood. One of the bacteria that infect the CF lung is Pseudomonas aeruginosa. This gram-negative bacterium is acquired from the environment of the CF lung, changing the expression of phenotypes over the course of the infection. As P. aeruginosa infections become chronic, some phenotype changes are known to be linked with negative patient outcomes. An important exoproduct phenotype is rhamnolipid production, which is a glycolipid that P. aeruginosa produces as a surfactant for surface-mediated travel. Over time, the expression of this phenotype decreases in expression in the CF lung.
The objective of this investigation is to evaluate how environmental changes that are related to the growth environment in the CF lung alters rhamnolipid production. Thirty-five P. aeruginosa isolates from Dartmouth College and Seattle Children’s Hospital were selected to observe the impact of temperature, presence of Staphylococcus aureus metabolites, and oxygen availability on rhamnolipid production. It was found that the rhamnolipid production significantly decreased for 30C versus 37C, but not at 40C. The addition of S. aureus spent media, in any of the tested conditions, did not influence rhamnolipid production. Finally, the change in oxygen concentration from normoxia to hypoxia significantly reduced rhamnolipid production. These results were compared to swarming assay data to understand how changes in rhamnolipid production impact surface-mediated motility.

Description
This thesis project examines the likely factors that cause students to drop out of Barrett, the Honors College. Honors literature regarding retention and attrition suggests four areas encompassing individual student attributes and honors program characteristics which may impact a student's decision to stay or leave an Honors College. The primary question in focus is, "Why do students leave the Honors College?" followed by the tertiary questions of, "what can be done to mitigate this occurrence?" and, "how does this affect the quality of an honors education?" Assessing attrition can be broken down into biographical, cognitive-behavioral, socio-environmental, and institutional-instrumental components. Students who graduated with honors and those who did not graduate with honors were assessed on these four components through survey methods and qualitative interviews to investigate specific reasons why students leave the honors program. The results indicated a wide array of reasons impacting student attrition, the most significant being negative perceptions towards (1) honors courses and contracts, (2) difficulty completing a thesis project, and (3) finding little to no value in "graduating with honors." Each of these reasons reflect the institutional-instrumental component of student attrition, making it the most salient group of reasons why students leave the Honors College. The socio-environmental component also influences student attrition through peer influence and academic advisor support, though this was found to be within the context of institutional-instrumental means. This project offers solutions to ameliorate each of the four components of attrition by offering standardized honors contracts and more mandatory honors classes, mandatory thesis preparatory courses instead of workshops, and emphasizing the benefit Barrett gives to students as a whole. These solutions aim at increasing graduation rates for future honors students at Barrett as well as improving the overall quality of an honors education.

Description
Undergraduate on-campus residential education is a topic of significant inquiry within the field of higher education, and specifically student affairs. It has become commonplace for institutions of higher education in the United States to leverage the intersections between academics and residence life in order to promote student success by offering on-campus housing options that strategically place students in residential communities that provide additional connection to the students' academic experience, often by major, college, department, or other focus areas. Such models vary by institution, but are often referred to as living-learning communities or residential colleges, depending upon their structure and goals. For example, Barrett, the Honors College on the Tempe campus of Arizona State University implements a residential college model within its student housing; honors students live and study together, with the addition of three "special communities" designed for students majoring in Engineering, Business, or the Arts. This honors thesis case study describes and investigates the impact the visual and performing arts Barrett residential community has upon its residents in their first-year college experience. Through the lens of student development theory, this research focuses upon examining this specific residential community in detail in order to gain an understanding of its effect upon residents' academic and personal well being.

Description
Structure is a critical component in drug development. This project supports antibody- facilitated structure determination for the following eleven membrane proteins: the human histamine and dopamine G protein-coupled receptors (HRH4 and DRD2) involved in a wide variety of pathologies such as allergies, inflammation, asthma, pain along with Parkinson's and schizophrenia respectively, the human cystic fibrosis transmembrane conductance regulator (CFTR), the human NaV1.8 voltage-gated sodium ion channel, the human TPC2 two-pore channel, the SARS virus proteins 3a, E and M, the MERS virus protein E and M, and the malarial chloroquine resistance transporter (PfCRT). Serum antibodies against these proteins were generated by genetic immunization, and both in vitro and in vivo expressed membrane proteins were created to characterize the serum antibodies. Plasmid clones were generated for genetic immunization, in vitro protein expression, and in vivo expression (HEK293T transfection). Serum antibodies were generated by genetic immunization of mice by gene gun. Genetic immunization promotes an immune response that allows for the generation of antibodies in the absence of purified protein. In vitro expression was accomplished through the novel technique: in vitro translation with hydrophobic magnetic beads (IVT-HMB). Transfections were performed using the HEK293T cell line to express the protein in vivo. The generated protein was then used in gel electrophoresis and silver stain and/or Western blot analyses to identify and visualize the proteins. These expressed proteins will allow for forthcoming characterization of the generated antibodies. The resulting antibodies will in turn enable structure determination of these important membrane proteins by co-crystallization.

Description
My grandmother, Mickey Gilbert, is the daughter of Italian immigrants, Clemente Saulino and Anna Moccia, who married in Italy and moved to a small mining town called Lynch, Kentucky in 1928, the year before my grandmother was born. Her family moved to an apartment in Cumberland, Kentucky where Clemente started a dry-cleaning business. Grandma's sister, Berenice, was born in 1931 and then her mother had a child every five years for 15 years, adding Joanne, Joe, and Tom to the family. Her family was religious and attended church every Sunday and holy day. Grandma went to a Catholic boarding school called St. Camillus Academy in Corbin, Kentucky from third grade through high school, spending holidays and summer vacations at home in Cumberland. She graduated in 1946 and attended Villa Madonna College in Covington, Kentucky that fall. She lived with three girls \u2014 Mary Catherine, Sara Lou, and Eulalie \u2014 at St. Joseph Heights, which was run by nuns. She spent a good amount of her holidays at Mary Catherine "Juggie's" home in Lawrenceburg, Kentucky which was closer than her own home in Cumberland. That is where she met my grandpa, Colly Gilbert. She graduated from Villa Madonna in 1950 with a B.A. in history and a secondary education teaching certificate. She married Allen Carlton "Colly" Gilbert, the youngest of seven children and a World War II veteran, in 1951 and they moved to Phoenix, Arizona where they had seven children: Anne, Carlton, Kelly, Monica, Marydith, Eileen (my mother), and Mark. Unfortunately, Colly lost a battle with kidney cancer in 1971 when their youngest child, Mark, was only ten years old. Grandma raised their children on her own after that and never remarried. She kept busy even after her children moved out by taking up gardening, knitting, and volunteering. She also spent time playing the piano and reading books. All of her children married, and all had at least one child except Carlton. Grandma has thirteen grandchildren and two great-grandchildren who all adore her. Anne, Carlton, Kelly, Monica, Marydith, and Mark eventually settled in different cities or states. My mother, Eileen, was the only one that stayed in Phoenix. She actually bought the house that her dad had built \u2014 the house that she grew up in \u2014 from my grandmother in 1992, and my grandmother moved to a patio home at Arcadia Green, less than a mile away. My grandma is an inspiration to our family. She taught us all the importance of enjoying the simple things in life and doing what we can for people. The values that she has passed on to us and the activities that she has inspired us to love make us healthier and happier people. Her parents instilled in her a love of family, friends, and life that she passed on to her children, and her children passed on to their children. Our family is close because of her \u2014 she is our lifeline. Her legacy is the tight bonds our family has woven.

Description
The devastating 2014 Ebola virus outbreak in Western Africa demonstrated the lack of therapeutic approaches available for the virus. Although monoclonal antibodies (mAb) and other molecules have been developed that bind the virus, no therapeutic has shown the efficacy needed for FDA approval. Here, a library of 50 peptide based ligands that bind the glycoprotein of the Zaire Ebola virus (GP) were developed. Using whole virus screening of vesicular stomatitis virus pseudotyped with GP, low affinity peptides were identified for ligand construction. In depth analysis showed that two of the peptide based molecules bound the Zaire GP with <100 nM KD. One of these two ligands was blocked by a known neutralizing mAb, 2G4, and showed cross-reactivity to the Sudan GP. This work presents ligands with promise for therapeutic applications across multiple variants of the Ebola virus.

Description
Disturbances in the protein interactome often play a large role in cancer progression. Investigation of protein-protein interactions (PPI) can increase our understanding of cancer pathways and will disclose unknown targets involved in cancer disease biology. Although numerous methods are available to study protein interactions, most platforms suffer from drawbacks including high false positive rates, low throughput, and lack of quantification. Moreover, most methods are not compatible for use in a clinical setting. To address these limitations, we have developed a multiplexed, in-solution protein microarray (MISPA) platform with broad applications in proteomics. MISPA can be used to quantitatively profile PPIs and as a robust technology for early detection of cancers. This method utilizes unique DNA barcoding of individual proteins coupled with next generation sequencing to quantitatively assess interactions via barcode enrichment. We have tested the feasibility of this technology in the detection of patient immune responses to oropharyngeal carcinomas and in the discovery of novel PPIs in the B-cell receptor (BCR) pathway. To achieve this goal, 96 human papillomavirus (HPV) antigen genes were cloned into pJFT7-cHalo (99% success) and pJFT7-n3xFlag-Halo (100% success) expression vectors. These libraries were expressed via a cell-free in vitro transcription-translation system with 93% and 96% success, respectively. A small-scale study of patient serum interactions with barcoded HPV16 antigens was performed and a HPV proteome-wide study will follow using additional patient samples. In addition, 15 query proteins were cloned into pJFT7_nGST expression vectors, expressed, and purified with 93% success to probe a library of 100 BCR pathway proteins and detect novel PPIs.
