Open Access Cookie Cutter, Chip Wolfe

Open Access Week at Gettysburg College

Print your own cookie cutter on a 3D printer using one of these files designed by Chip Wolfe, Digitization Specialist/Access Services Technician at Embry-Riddle Aeronautical University.

The .dae file does not need to scaled; the .stl file will need to be scaled. The cutter was designed to be 14 mm deep and 85 mm top to bottom, but can be rescaled to whatever size you like.

UPDATE 10-25-16: Stephen Gray of University of Bristol modified the file (it reportedly had a spike that prevented it from fitting on the printer bed). The modified version is being shared here in hopes …

Exploring The Potential Of Miniature Electrodynamic Tethers And Developments In The Miniature Tether Electrodynamics Experiment , Nikhil Shastri, Alexandria Western, Abhishek Cauligi, Roshan Radhakrishnan, Bret Bronner, Rupak Karnik, Siju Varughese, Brian E. Gilchrist, Jesse Mcternan, Sven BiléN

Small Satellite Conference

The success of nanospacecraft has spurred an interest in using even smaller satellites for longer-duration, constellation scale missions, requiring the use of a propulsion source on board to counteract the effects of drag and for coordination and maneuverability. Previous papers have shown that the use of short electrodynamic tethers (EDTs) has the potential to provide propellentless propulsion for drag make-up and the ability to change orbits of these small satellites. The Miniature Tether Electrodynamics Experiment (MiTEE) mission is a student-led technology demonstration mission by the University of Michigan to demonstrate the use of these short EDTs in a 1U CubeSat …

A Partnership Approach To Protecting And Improving Water Quality In The Shellfish Watersheds Of Pierce County, Cindy Callahan, Erin Ewald, Barbara Ann Smolko, Ray Hanowell

Salish Sea Ecosystem Conference

Commercial shellfish growing is a significant economic driver on the Key Peninsula of Pierce County, Washington. In response to the downgrades of several shellfish areas in the 1990’s and early 2000’s and the establishment of Shellfish Protection Districts and Closure Response Plans, it was recognized that a more proactive approach was needed. In an effort to build cooperation and a partnership across Pierce County, and address bacterial contamination in the shellfish growing areas, a Pierce County Shellfish Partners Strategic Plan was developed and formalized in March of 2013. The partnership initially included Pierce County Surface Water Management (SWM), Pierce Conservation …

Computational Inference Of Biological Networks Using Circadian Signals, Devon Cormack

CLAS: Colby Liberal Arts Symposium

The work that I will be presenting demonstrates that through observation of the circadian dynamics of the suprachiasmatic nucleus (SCN), you can infer the network connectivity between cells in the SCN for simple network structures. Circadian pacemakers and damped oscillators will be discussed with reference to their importance in the resynchronization of the circadian system and how the resynchronization process can be used to infer network connectivity. Connectivity inference will be discussed for both biological and simulated systems. Inference methods were developed, tested and evaluated through model simulation in MATLAB.

Entextualizing Debodified Humanities: (A)Symmetrical Spectacles, Tortures And Coercionsan Analysis Of The Deaths Of Women And Men Through Feminicidios And Ejecuciones In Cd. Juárez, Chihuahua, Amber Ramirez

CLAS: Colby Liberal Arts Symposium

Cd. Jurez, Chihuahua, border city to El Paso, TX, has been reputed by many as the the worlds most murderous city. This city has acquired fame from not only the horrors of sexualized killings of women, but also the constant day-to-day executions by narcotraficantes (drug traffickers) in the cartel wars, which the media and popular culture have promulgated. From 1993 to 2005, due to the lack of prosecution of the perpetrators, approximately more than 370 women died in the feminicidios (women murders), 50% of which showed signs of sexual assault and abuse (Rodrguez-Haussguy 1). Added to this are more than …

Self-Monitoring Across Real World And Digital Contexts, Dylan Nisky, Melissa Preziosi, Caroline Southwick

CLAS: Colby Liberal Arts Symposium

Our study examined self-monitoring consistency and mean-levels of self-monitoring across four different contexts: Social networking sites (SNS), email, texting-like communication, and face-to-face. Participants completed a total of five self-monitoring scales, one for each context and a general scale with no context given. Before each context-related scale participants answered general demographics questions about their experience in each context to help orient themselves within the context. We expect that self-monitoring will show a significant general level of consistency across all online contexts observed and face-to-face contexts. We also predict that less formal or more expressive forms of Internet communication like SNS and …

The Synthesis Of Triple-Helicene And Semi-Fullerene Using Flash Vacuum Pyrolysis Techniques, Abebu Kassie

CLAS: Colby Liberal Arts Symposium

This work describes our approach to the synthesis of triple-helicene and semi-fullerene using flash vacuum pyrolysis (FVP) techniques. The precursor is designed to generate a tri-acetylene that can rearrange to tri-vinylidene under high temperature FVP, which then participates in intramolecular cyclization to give triple-helicene . Based on known reactions, the semi-fullerene is anticipated to be a secondary product from triple-helicene. Preparation of precursor began with a triple Suzuki-Miyaura reaction converting 1,3,5-tri-bromobenzne into ketone-derivative. The second step of the reaction was performed by reacting the ketone-derivative with phosphorus pentachloride to make 2,2\-bis(1-chlorovinyl)-5-(2-(1-chlorovinyl)phenyl)-1,1:3,1\-terphenyl. We are now subjecting 2,2\-bis(1-chlorovinyl)-5-(2-(1-chlorovinyl)phenyl)-1,1:3,1\-terphenyl to FVP experiments to …

The Electric Guitar And American Counterculture, Daniel Nesvet

CLAS: Colby Liberal Arts Symposium

The American counterculture movement, prevalent in the 1960s and 1970s, used music as a medium for expression. Rock n roll became the sound of a generation, proclaiming the grievances and hardships young adults felt. With the Vietnam War and Civil Rights movement reaching their peaks, American counterculture followed suit. The invention of the electric guitar changed music forever, allowing musicians to create new sounds in order to express their inner emotions. Artists such as Jimi Hendrix, Eric Clapton, and Jimmy Page became innovators, creating a new genre. Protest songs such as Fortunate Son and Ohio became anthems for the increasingly …

Structural Characterization Of The Major Dna-Dna Cross-Link Formed By Epichlorohydrin, Edward Chuang

CLAS: Colby Liberal Arts Symposium

Epichlorohydrin (ECH) is a potential human carcinogen that is used in the industrial production of epoxy resin, adhesives, plastics, insecticides, glycerin, and pharmaceuticals. ECH is a bifunctional alkylating agent with the ability to form monoadducts with DNA as well as to cross-link DNA covalently. An in vitro study was done to react ECH with guanosine to help characterize the mechanism of the cross-linking reaction. Liquid chromatography mass spectrometry was used to determine the intermediates and products of the reaction. It was found that the major monoadduct intermediate formed had a chlorine atom, suggesting that the epoxide of ECH is the …

Race And Tennis, Elizabeth Bogo

CLAS: Colby Liberal Arts Symposium

Last semester I did a presentation on Race and Tennis, which I would love to present again. This presentation circulates around the question, How have African Americans influenced the history of tennis? I plan on discussing the history of tennis, the initial oppression and segregation of African Americans in the sport, the American Tennis Association, and the crossing of racial barriers, beginning with Althea Gibson. I will also talk about other players and their influence on the sport, such as Arthur Ashe, Serena and Venus Williams, as well as James Blake.Through this presentation I hope for the audience to learn …

Re-Defining Mental Illness, Anna Krauss

CLAS: Colby Liberal Arts Symposium

As an often ostracized group from society, the mentally ills path to social acceptance is not easy. To fully understand our current health care system in regards to mental illness, the steps one takes when diagnosed as mentally ill as well, as the hardships one will face, this paper will address the question: to what extent is the effectiveness of modern diagnosis and treatments on mental illnesses? From sociological theory to the biological sciences, this topic has been closely scrutinized and identified as a prevalent issue in our society. Due to the complexity of this topic, however, no one definite …

La Métamorphose En Poésie, Alexandra Yorke

La Rupture En Poésie, Ginger Brooker

CLAS: Colby Liberal Arts Symposium

I explored the idea of separation and heartache in my poetry this semester. The work of Frost, Apollinaire, and Mallarm inspired the structure and themes of my poems.

Does Overtraining And Choline Supplementation Make Memories About Objects Resistant To Perirhinal Cortex Damage?, Alexandra Brown

CLAS: Colby Liberal Arts Symposium

Previous research confirms that medial temporal lobe structures make vital contributions to learning and memory. One structure in this region, the perirhinal cortex, appears to have a specialized role in supporting the capacity of rats to learn about and remember previously-encountered objects: damage to the perirhinal cortex interferes with rats abilities to remember familiar objects and to learn about new ones. Interestingly, rats that receiving extensive experiences with the same objects over the course of several weeks show preserved memory for those objects, though they still exhibit impaired learning of new objects. These findings suggest that information about the objects …

Coherence And Quantumness In Photosynthesis, Brian Doolittle

CLAS: Colby Liberal Arts Symposium

Photosynthesis is extremely efficient at converting light into chemical energy. The energy conversion occurs in the FMO pigment-protein complex. The FMO has been extensively studied. Experimental results show that there is a longterm coherence lasting on the order picoseconds. However, the results fail to identify if the coherence is electronic or vibronic and if it is a classical or a quantum effect. To analyze the system, we are using a theoretical model based on a quantum adiabatic path integral (Quapi). With our simulation, we are trying to parameterize the long-term coherence observed and determine if the system is classical or …

The Role Of Recent Social Media In Public Apology: Japan's History Of Comfort Women, Emily Harper

CLAS: Colby Liberal Arts Symposium

The highly charged, political issue of comfort women, girls forced into sexuality slavery by the Japanese Imperial government during WWII, has been one of the most controversial and wildly misrepresented historical moments in East Asian history. This study looks specifically at the public statements and apologies being made by members of the Japanese political elite in response to a final push by former comfort women looking for recognition and Japanese repentance. How a public apology regarding comfort women will affect Japans attempt at further globalization, as well as the role of social media in the creation and recreation of historical …

Effects Of Professor, Student Gender Agreement On Learning, Emily Berry, Seth Butler

CLAS: Colby Liberal Arts Symposium

Academic performance has been a major component in society. Educators and researchers have long studied the best way to get students to learn and perform at their maximum abilities. Only a few past studies have looked at student, professor gender concordance as a determinant in student learning. This study aims to investigate the effects of gender agreement between professors and students on student learning. Surveys were distributed to students in order to collect information on gender, learning, grades, class sizes, and other possible confounding variables. A chi squared contingency test, a one-way ANOVA test, and a two sample t-test were …

Shear-Induced Structures In Colloidal Suspensions, Guram Gogia

CLAS: Colby Liberal Arts Symposium

Soft matter systems are known to exhibit a range of phase behaviors when driven out of thermodynamic equilibrium. Using a confocal rheoscope, we investigated configurations of monodisperse colloidal particles under oscillatory shear. In the absence of shear, colloids, like other soft matter particles, exhibit equilibrium behavior, dominated by random Brownian motion. When colloidal suspensions get sheared, various ordered structures emerge. By modifying shear cell gap width and shear frequency and amplitude, we observed HCP crystalline structure and buckled phase, as well as unexpected density fluctuations. Namely, there were crystalline structured stripes of particles arranged perpendicular to the shear direction. This …

Issues Of Community: Rules Of Exclusion Ft. The Hijras Of Dhaka City, Bangladesh, Hiya Islam

CLAS: Colby Liberal Arts Symposium

The purpose of the project is to philosophically argue and elicit issues related to exclusion that arise within the framework of a community. Communities consist of a certain group of individuals with certain attributes and a set of rules governing their interactions with each other and those outside their community. This phenomenon of a communitys existence is characterized by its social rules: who constitutes it, who is excluded from it, how one is excluded and why. This is the idea I want to invoke when I refer to community. Understanding that the rules vary according to communities, I look at …

Career Trajectories In Finance: Individual Motivations And Navigating External Influences, Kathryn Griffin

CLAS: Colby Liberal Arts Symposium

The purpose of this qualitative sociological research study is to look at the career trajectories of Colby alumni currently working in finance in addition to seeing if variables such as gender and the cohort they graduated in may have played a role in their career development. I am interested in how institutional practices within American society in general, and the financial sector specifically, may perpetuate gender inequality or gendered patterns of labor market participation. With these findings, I hope to paint a picture as to what Colby graduates may face if they are interested in pursuing the field of finance …

Towards Sullivan's No Wandering Domain Theorem, Kyle Hawkins

CLAS: Colby Liberal Arts Symposium

A look into the long-term behavior of complex dynamical system, building up the theory and culminating in the No Wandering Domain Theorem. With this, and other results, we may identify in what ways this function behaves on its Fatou set.

Parametric Analysis Of Galaxy Morphology From Simulated Galaxy Mergers, Ryan Cole

CLAS: Colby Liberal Arts Symposium

It is suspected that galaxy mergers play an important role in the formation and evolution of galaxies. Their influence is particularly significant in the early universe when galaxies are closer together. Using a set of high-resolution cosmological simulations, we analyze the effect of mergers on the evolution of galaxy structure from an observational perspective. Our method includes modeling the full electromagnetic spectrum of the galaxies in order to visualize the simulations in a realistic way. The subsequent analysis of the resulting morphology allows us to gain a better understanding of the physics that drives galaxy formation. Furthermore, we develop the …

Aryl Alkyne Dimerization And Subsequent Snar Reactions, Tyler White

CLAS: Colby Liberal Arts Symposium

The function of an alkyne as an electron-withdrawing group (EWG) in nucleophilic aromatic substitution (SnAr) reactions has been established by the Katz lab during the past few years. The function of EWGs in SnAr to form macrocyclic organic molecules with oxygen linkers between aromatic carbon systems called oxacalixarenes has been the long-standing interest of the Katz lab. To better understand the way the acetylene group can be used as a modifying substituent in aromatic systems, the homo-coupling of aryl acetylene groups has been explored. This research was followed with subsequent investigation into the resulting diyne functional group as a sufficiently …

Embroidery And Gender In Chinese History, Tashi Palmo

CLAS: Colby Liberal Arts Symposium

Chinese Embroidery has been a object of fascination, and easy to find once one started looking for it. In Chinese history, many things are embroidered and the embroidery itself holds symbolic meaning to it. Looking at the symbolic meanings of each embroidery, gender roles are clearly noted especially in a society based on Confucius values at the time. Not only were the embroidered art are gendered, but the practice of embroidery itself was gendered female. Women were responsible for domestic works, so they stayed inside the four walls of their house and took care of the children, cleaned the house …

Leap: Land Endowment Action Plan For Sustainable Colby, Natalie Fischer, Victoria Palffy

CLAS: Colby Liberal Arts Symposium

Colby opened the doors to its biomass plant in 2012, declaring carbon neutrality shortly after in 2013. This was not just a victory for the colleges environmental efforts, but it was also the beginning of a new energy chapter. This chapter gave Colby more opportunities to continue as a pioneer in the sustainability movement. This paper analyzes the chemical and economic feasibility of using land endowments to fuel the biomass operations. The scientific approach starts by looking at the fuel source and its specific context in Maine in order to determine the properties that it offers. Knowing more about the …

P-19 Hcnabc Operon Transcription Of Pseudomonas Putida Under Varying Iron And Oxygen Concentrations And Culture Age, Christine Lee

Honors Scholars & Undergraduate Research Poster Symposium Programs

The species Pseudomonas putida produces hydrogen cyanide (HCN) through the transcription of the hcnABC operon. The purpose of this experiment is to determine how the hcnABC operon is affected by varying levels of iron and oxygen, and age of bacteria culture. To test this, P. putida is grown under five conditions: the presence of iron, the absence of iron, with aeration, without aeration, and without iron and aeration. At 8, 18, and 30 hours, the cultures are assessed for HCN production and cell density. HCN production is measured via bioluminescence; light emission occurs whenever HCN is produced because the modified …
