A Taste Of Their Home: Lunar New Year Was The Occasion, But Bridge Building Was The Mission For Chinese Students, Kardelen Koldas

Colby Magazine

Inside Roberts Dining Hall one night in February, the first to arrive were already filling up their plates with signature Chinese dishes: vegetable egg rolls with plum sauce, sweet rice dumplings with red bean paste, and Sichuan spicy boiled fish. White and red parasols hung above the food. Red lanterns and fu (福) signs livened up the walls for good fortune, luck, and happiness. Chinese flags proudly stretched from one column to another.

When An Economist Is A Mentor: For Yang Fan, Colby’S Teaching Philosophy Was The Right Fit, Kardelen Koldas

Colby Magazine

They say follow your passion to wherever it takes you. Yang Fan, the new Todger Anderson Assistant Professor of Investing and Behavioral Economics, did just that. He followed his passion for teaching and changed coasts, from West to the East. Now, he’s helping his students find and pursue their passions as well.

Doors Pushed Open: For Devin Gibbs, College Seemed Like A Longshot--Until It Wasn't, Kardelen Koldas

Colby Magazine

Before enrolling, Devin Gibbs ’14 received an invitation from Colby. The letter offered to bring him to campus and provide accommodations so he could get a feel for the school. What it didn’t say was he had, in essence, been admitted. Gibbs, who lived in Waterville just minutes from campus, thought the letter was a scam. “I had never gotten anything for free before,” he said.

Paddling The Green River, Stephen Collins

Colby Magazine

If you’ve followed the career of outdoor writer Heather Hansman ’05, you’ll recognize her gasping for air after dumping her raft-load of customers into a Class V rapid on the Gauley River, avoiding avalanches in deep backcountry powder in the Rockies and Cascades, or dodging toxic algae and scary big koi swimming in an urban lake in Seattle.

A Better Way, Gerry Boyle

Colby Magazine

Alane O’Connor ’96 studied environmental economics at Colby. Associate Professor of Statistics Liam O’Brien first studied physics and mathematics.Together the pair has combined their broad experience to produce groundbreaking research that is changing the way clinicians around the world treat pregnant and opioid-addicted women and their unborn children.

So what gives? How, after four years on Mayflower Hill, do these Colby alumni have an outsized impact in a fintech company that is focused on, for example, changing the way municipal bonds are traded? What makes them able to dive in and figure it out? “That’s part of the liberal arts education,” said Associate Professor of History John Turner, who taught Tagg Martin ’13, history major turned MarketAxess go-to analyst. “You’re always learning. … You are always going to be mastering something, as opposed to having mastered.”

“Quietly Incomplete”: Academic Historians, Digital Archival Collections, And Historical Research In The Web Era, Donald Force, Bradley Wiles

Journal of Contemporary Archival Studies

Since the early 1990s, archives institutions largely have approached digital archival collections with an “if we build it, they will come” mentality. But the extent and motivations of use for traditional and emerging patron groups are constantly evolving, and the factors or conditions that characterize use vary wildly in the web environment. As part of a broader study investigating how academic historians utilize and interact with digital archival collections, this paper details the findings of a pilot project involving a citation analysis, survey, and semi-structured interviews with academic historians from a medium-sized Carnegie Research 1 university. This limited exploratory study …

Tungsten: The Strongest Natural Metal On Earth, Haley E. Holland, Razan Khadka, Lee Marble, Kaleb Tutor

ME 4133/6133 Mechanical Metallurgy

The overall objective of this project was to construct a process-structure-property-performance (PSPP) map for a chosen metallic material. The material chosen by the group is tungsten (W). Tungsten is a rare, naturally occurring element and is usually found in the form of ores. It is known predominantly for its ability to withstand extreme temperatures, as well as its high tensile strength. The PSPP map displays many specifications of tungsten in each of the four categories and further details regarding each specific linkage, or subcategory, within the map are written throughout the research paper.

Along with the four specific categories outlined …

An Analysis Of The Effects Of Process, Structure, And Properties On The Performance Of The Ti6al4v Alloy, Brad Jay Sampson, Loubna Ifqir

ME 4133/6133 Mechanical Metallurgy

Ti6Al4V (pronounced Ti-64), is a titanium alloy used in a variety of engineering applications including the aerospace, automotive, and biomedical industries. Ti6Al4V is made up of a combined ɑ-β microstructure, which provides it with many valuable properties such as high strength, low weight, high melting point, corrosion resistance, and biocompatibility. [1] For years, casting and forging have been the traditional processes used for the manufacturing of Ti6Al4V components, but recent interest in the additive manufacturing of Ti6Al4V through the Electron Beam Melting (EBM), Selective Laser Melting (SLM), and Directed Energy Deposition (DED) methods has been gained. The goal of this …

Research into the structure and properties of duplex stainless steel and the processes it undergoes will indicate how duplex …

Ar400 Wear Plates, Jase Tatum, Bryson Miller, John Howell, Aaron Alexander

ME 4133/6133 Mechanical Metallurgy

Wear resistance is an invaluable performance metric for most metallic components found in mechanical systems. Our research focused on AR400, a steel alloy known for its wear resistance capabilities, in an effort to determine what factors might be attributed to its performance in wear applications. After establishing the processing techniques and resulting material structures that give AR400 such an edge in extreme wear conditions, our goal is to determine indicators of wear resistance that can be used to distinguish excellent wear resistant alloys from average or subpar performers against wear.

3xx Aluminum Alloys For Ice Implementation, Kyle A. Taylor, Eric Cleckner, Jeffery Garrett

ME 4133/6133 Mechanical Metallurgy

The material to be explored for the purpose of this project relates to the Aluminum alloys used in the majority of modern engine “heads” and a number of engine “blocks”. The Aluminum used for these engine applications vary slightly across different manufacturers in their processing, structure and ultimate properties, despite their nearly identical performance applications. Part of the interest in this particular subject is the slight variations across manufacturing that result in different performance. Regardless of idiosyncrasies, these Al alloys are expected to perform under varying temperatures, with the ability to elastically deform and return to their original shape. They …
