Heterogeneous Thermal Effects On Structural-Grade Steel, Eric Wickersham

Williams Honors College, Honors Research Projects

The AISC Steel Construction Manual covers structural steel design while at atmospheric and elevated temperatures. The manual does not, though, cover what happens to the steel after it has cooled from elevated temperatures. To fill in this knowledge gap, A36 steel was studied with respect to three main criteria: time, temperature, and cooling. Time was sub-divided into a standard burn (17-20min) and a prolonged burn (90min). Temperature was sub-divided into an average burn (600-800⁰F) and an extreme burn (>1200⁰F). To reach such temperatures, a forge was constructed and used during the burning process. Cooling was sub-divided into standard (air …

To Trade Or Not To Trade: Public Opinion And Trade Liberalization In Chile, Nicholas J. Surkala Ii

Williams Honors College, Honors Research Projects

Public opinion polling has been a major source of information regarding opinion data from respondents within a geographical area. Trade liberalization, or reducing barriers to trade, has been a source of controversy throughout history, more recently since the world has globalized. In this paper, four social factors will be analyzed based on responses to public opinion questions to determine if these factors influence people’s opinions on trade liberalization. Chile has been used as a model for successful trade liberalization in Latin America, and is the country analyzed in this paper.

The Role Of Tgfβ1 And Ep Receptors In The Differentiation Of Normal And Diseased Lung Fibroblasts, Madison A. Hexter

Williams Honors College, Honors Research Projects

Fibroblasts, and their differentiation into myofibroblasts, are important in the pathology of several lung diseases including asthma and idiopathic pulmonary fibrosis (IPF). The differentiation process is dependent on several factors, such as soluble factors like transforming growth factor beta 1 (TGFβ1) and mechanical signals such as matrix stiffness. Additionally, the soluble arachidonic acid metabolite Prostaglandin E₂ (PGE₂) prevents TGFβ1 induced differentiation of fibroblasts to myofibroblasts, but the molecular mechanism is not completely understood¹⁵. Transient Receptor Potential Vanilloid 4 (TRPV4), a mechanosensitive ion channel, has previously been implicated in the differentiation of cardiac fibroblasts^12,13. …

Impacts Of Water Sources On The Effectiveness Of Point-Of-Use Water Treatment, Robert Brophy

Williams Honors College, Honors Research Projects

Disinfection of drinking water provides a safe, reliable, and clean water supply and has been protecting public health successfully throughout the 20th century. However, factors such as deteriorating infrastructure, introduction of microbial pathogens, or disinfection byproducts create problems and reduce the effectiveness of a drinking water treatment plant. Every day the public is drinking known carcinogens that are regulated by the EPA and tested for quarterly by treatment plants. To combat rising costs involved with upgrading source water treatment, point-of-use treatment is a popular option that treats water as it leaves the distribution system instead of being treated before discharge. …

What Must There Be To Account For Being?, Dillon T. Mccrea

Williams Honors College, Honors Research Projects

The purpose of this essay is to identify what I consider to be core philosophical arguments supporting the thesis that being subsists. The design of the thesis is as follows: First, I will attempt to identify arguments supporting the claim that we posit the universe and all of its content in relation to the question of being. Second, I will identify arguments supporting the claim that it is incoherent to claim that being is merely a function of the existence of individual entities, and that all entities share being in common. Third, I will identify arguments supporting the claim that …

According to the National Highway Traffic Safety Administration (NHTSA) Safety Vehicle Research, 29% of all vehicle accidents are rear end collisions. Many are a result of failure to respond to a slowing or stopped vehicle. [1] The purposed LED rear lighting system will incorporate attention getting techniques to increase vehicle visibility to other drivers. Due to the small size and stature of the 2015 human powered vehicle called Joey, it will be out of the ordinary when traveling on roadways. “Three in four (72%) bicyclists who rode after dark said they tried to do something to make themselves more visible.” …

Calculators In High School Classrooms, Adam P. Rohrabaugh, Clay M. Cooper

Williams Honors College, Honors Research Projects

In today’s mathematics classrooms, calculators are becoming incredibly well known and used almost daily. However, there has been a common question about the use of these calculators: Is too much exposure to calculators causing students to become dependent on them and consequently start to forget basic addition, subtraction, multiplication, and division, leading into confusion on other mathematics topics because the most basic foundation of mathematics is not there? The purpose of this paper is to discuss both sides of this question by looking at different studies as well as provide our own experiences with this subject while working in different …

Case Study: Observing The Effects Of Length Of Exposure To Mnv On Mice Colonies, Beau Brown

Williams Honors College, Honors Research Projects

Four groups of experimental mice are studied in this experiment following intentional exposure to murine norovirus (MNV). Two groups are exposed to the virus at different points in their lives, and the other two are not infected and studied alongside the other groups as controls.

Past research has indicated that B and T immune cells are not essential to MNV resistance. Additionally, antibody production against MNV has shown to be slow as infection progresses. Thus, the expected results from the experiment are that the mice with longer infections of MNV will have larger quantities of IgG than those more recently …

The Takeover Of Standardized Tests, Karlie M. Lieberth

Williams Honors College, Honors Research Projects

Diane Ravitch once said, “Sometimes the most brilliant and intelligent students do not shine in standardized tests because they do not have standardized minds”. Standardized testing is a very controversial issue occurring in our school systems today. Standards hold schools and teachers accountable for properly progressing our youth through school. However, is administering the same exact test to every child in every school district the best way to measure growth? There are many factors that makes up a school and student body such as poverty, cultural beliefs etc. These factors are not addressed in the standardized tests that our students …

Microstructure And Deformation Mechanism Analysis Of Carbonate Rock Located In An Anticline, Natalie R. Zidd

Williams Honors College, Honors Research Projects

Rock samples were collected from the Tensleep formation in the Seminoe Mountains located in Carbon County, Wyoming. These samples were analyzed to determine the deformation mechanisms operating during small scale displacement faulting. There are three distinct zones included in the sample which includes the undeformed Tensleep, fine grained layers with grain size variation, and porous layers with grain size variation. The microstructures in the fine grained layer were consistent with deformation by crystal plastic deformation mechanisms; whereas, the microstructures in the porous layer were consistent with brittle deformation mechanisms. The microstructures in these rocks are nearly identical to those observed …

The Diameter Of A Rouquier Block, Andrew Mayer

Williams Honors College, Honors Research Projects

For my Honors Research Project, I will be researching special properties of Rouquier blocks that represent the partitions of integers. This problem is motivated by ongoing work in representation theory of the symmetric group. For each integer n and each prime p, there is an object called a Rouquier block; this block can be visualized as a collection of points in a plane, each corresponding to a partition. In this group of points, we say a pair of points is “connected” if certain conditions on the partitions are met. We compare each partition with each other partition, add edges when …

It can express strength and confidence or emphasize vulnerability.

Through this study, the use of specific studio lighting techniques accentuates design elements of a highly curated collection of avant-garde, 21^st century garments. Drape, texture, form, and luster are but a few …

Lipid-Protein Interactions Via Fluorescence Quenching In Small Unilamellar Vesicles, Talia Kordahi

Williams Honors College, Honors Research Projects

Studying peptide interactions with model membranes have aided in understanding protein-lipid interactions more clearly. In this report, fluorescent small unilamellar vesicles (SUVs) of a known composition were made. Two peptides, RND1 and MARCKS, were also fluorescently labeled and added to a solution of SUVs. The interactions between these were observed via fluorescence quenching, read out with a spectrofluorimeter. In addition, two environments of buffer were tested: 1X PBS and 0.1X PBS. After obtaining data, it was concluded that MARCKS quenched the SUVs more than RND1. This could be due to the presence of more lysine amino acids in MARCKS, which …

Williams Honors College, Honors Research Projects

In this thesis, a one dimensional model is developed to investigate the initial stages of corrosion in a fastener assembly consisting of a stainless steel fastener and aluminum 7075 as the plate. Differential equations are formulated and solved to determine the profiles for the potential, the oxygen concentration, and the aluminum ion concentration in the crevice, and also the potential in the bulk electrolyte. This fastener system exhibits galvanic corrosion, pitting corrosion, and crevice corrosion. It is found that the potential decreases monotonically down the length of the crevice, the oxygen concentration decreases exponentially down the length of the crevice, …

Practical Implications Of Learning From Unsuccessful Retrieval Attempts, Ann C. Rossmiller, James R. Houston

Williams Honors College, Honors Research Projects

Recent findings suggest that retesting oneself facilitates better learning than studying alone. Building off previous experiments where correcting participants has significantly increased correctness, the current study furthers our understanding about learning from unsuccessful retrieval attempts by manipulating the frequency of correction. Using a set of 42 associated word pairings, each participant was exposed to two blocks where they would memorize the word pairs. This was followed by two quizzing blocks and a final exam block where participants were asked to write down the associate to the stimulus presented on screen. Frequency of correction was manipulated during the quizzing blocks where …
