Software Package For Mass Spectrometry Isotope Analysis And Extraction, Michael Porter, Dr. John Price

Journal of Undergraduate Research

Proteins are involved in nearly every cellular process. They transport molecules, replicate DNA, catalyze reactions, respond to stimuli, and form the structural framework of the cell. The diversity of protein function has led to an interest in understanding the cellular production and control of individual proteins which in turn is key to understanding how the cell responds to the environment and what occurs on a molecular level during disease.

Solving The Structure Of The Raptor-Cct Complex, Grant Ludlam, Barry Willardson

Journal of Undergraduate Research

The protein Raptor is an essential component of the mechanistic target of rapamycin (mTOR) cell signaling complex 1 (mTORC1) (1). The mTORC1 complex is a master regulator of cell growth, making it a high-priority target in cancer and inflammation research (2). Before Raptor can be assembled into the mTORC1, it is first folded by the chaperone protein cytosolic chaperonin containing TCP1 (CCT). CCT is composed of two rings of 8 different subunits, which together form a barrel shape. CCT substrates are folded in the 85 Å wide folding cavity inside the barrel.

Trace Element Analysis Of Quartz Grains In The Wah Wah Springs Tuff And Granodiorite Intrusion, Michael Jensen, Dr. Eric Christiansen

Journal of Undergraduate Research

The Wah Wah Springs Tuff and the Wah Wah Springs Intrusive Granodiorite are both part of the Indian Peak caldera complex in southwest Utah, an area of intense volcanic activity 30 million years ago. This time period is known for explosive silicic activity due to the subduction of the Farallon Plate along North America’s western edge. In the eruption connected with the Wah Wah Springs an estimated 5,900 km³ of magma came out of the Earth, making it one of the largest known explosive eruptions in our planet’s history. This massive eruption was partially dependent upon the changing temperatures …

Determining The Size Of A Light Source Using The Hanbury Brown And Twiss Effect, Adam Kingsley, Dallin Durfee

Journal of Undergraduate Research

In 1956, Hanbury Brown and Twiss (HBT) published a paper¹ on a method of determining the angular size of a star by comparing the intensities gathered from two detectors. They used this effect by using two photomultiplier tubes and by increasing the distance between them, saw a drop in the correlation between the currents. Because the correlations are made by the interference at the detectors but only the intensity is measured, the effect is sometimes referred to as intensity interferometry.

The idea arose to use the HBT effect to teach undergraduates various principles of light in a lab setting. …

Phase Matching In Laser Generated Harmonics, David Squires, Justin Peatross

Journal of Undergraduate Research

In this mentored research project, we investigated how intense laser light is scattered by samples of gas. In particular, we measured light scattered in non-phase-matched directions perpendicular to the laser beam.

According to classical phase matching, the intensity of light scattered from a sample depends on whether the sample is best approximated as a continuous medium or a collection of discrete emitters (Figure 1). In the former case, as the angle between the phase-matching direction and the radiated harmonic approaches π/2 radians, the intensity of that radiated harmonic light approaches 0. In the latter case, the light intensity reaches …

Determination Of Fine Particulate Matter Composition And Development Of The Organic Aerosol Monitor, Paul Michael Cropper

Theses and Dissertations

Tropospheric fine particulate matter (PM) poses serious health risks and has a significant impact on global climate change. The measurement of various aspects of PM is challenging due to its complex chemical nature. This dissertation addresses various aspects of PM, including composition, measurement, and visibility. The U.S. Environmental Protection Agency (EPA) proposed a new secondary standard based on visibility in urban areas using 24-h averaged measurements of either light scatter or PM concentration. However shorter averaging times may better represent human perception of visibility. Data from two studies conducted in Lindon, UT, 2012, and Rubidoux, CA, 2003, were used to …

Perforated Hollow Core Waveguides For Alkali Vapor-Cells And Slow Light Devices, Matthieu C. Giraud Carrier

Theses and Dissertations

The focus of this work is the integration of alkali vapor atomic vapor cells into common silicon wafer microfabrication processes. Such integrated platforms enable the study of quantum coherence effects such as electromagnetically induced transparency, which can in turn be used to demonstrate slow light. Slow and stopped light devices have applications in the optical communications and quantum computing fields. This project uses hollow core anti-resonant reflecting optical waveguides (ARROWs) to build such slow light devices. An explanation of light-matter interactions and the physics of slow light is first provided, as well as a detailed overview of the fabrication process. …

Accepting Evolution And Believing In God: How Religious Persons Perceive The Theory Of Evolution, Katherine F. Manwaring

Theses and Dissertations

Students frequently hold an incorrect view of evolution. There are several potential barriers that prevent students from engaging evolutionary theory including lack of knowledge, limited scientific reasoning ability, and religiosity. Our research provides tools for overcoming barriers related to religiosity and diagnoses the barriers preventing students from fully engaging in learning the theory of evolution. This was a two-part study. The first part of our study addressed two hypothesized barriers to learning evolutionary theory among members of The Church of Jesus Christ of Latter-day Saints (LDS or Mormon): (1) religious views stemming from incorrect understanding of the Church's neutral stance …

Inversion Characteristics Of A Buoyant Cylindrical Puck During Oblique Water Impact, Zachary Crawford Smith

Theses and Dissertations

The Apollo Command Module had a tendency to flip over upon impact with the ocean surface after returning from space (9/19 times). In an effort to better characterize the inversion process for future water landing vehicles, experimental results for a simplified buoyant cylindrical puck impacting the water surface are presented. This study focuses on the dependence of inversion upon vertical velocity, horizontal velocity, and the pitch angle of the puck relative to the free surface. High-speed images reveal an asymmetric cavity that forms upon water impact. The asymmetric cavity then collapses, applying a moment, which can be sufficient to invert …

Microbial Pretreatment Of Waste For Anaerobic Digestion, Braden Myers, Jaron Hansen

Journal of Undergraduate Research

The aim of this research was to demonstrate Caldicellulosiruptor bescii is a feasible microbial pretreatment of lignocellulose for enhanced production of biogas when coupled with secondary anaerobic digestion. Before anaerobic digestion of waste can reach its maximum energy production potential, economically sound methods for pretreatments that allow increased digestion of waste materials must be developed. Many types of waste cannot be broken down sufficiently by anaerobic digestion alone. Overcoming this hurdle through successful feedstock pretreatment would unlock a vast potential supply of renewable energy feedstock materials.

Measuring Frequency Noise For Use In Preventing Mode Hops In Extended Cavity Diode Lasers, Mckinley Pugh, Dallin Durfee

Journal of Undergraduate Research

Diode lasers are useful in physics because they are relatively cheap and robust, they are available in a number of wavelengths, and they are tunable. However, because diode lasers have large bandwidths compared to atomic resonances, a reflection grating is added outside the laser. This creates the extended cavity in extended cavity diode lasers (ECDLs) and forces the lasers to operate at a narrower line width, one acceptable for use in atomic physics. Unfortunately, because the ECDL has many factors trying to control the wavelength of the laser (e.g. temperature, current, grating angel and position) small changes in the lasers …

Girl’S Cybersecurity Camp, Sarah Cunha, Dale Rowe

Journal of Undergraduate Research

In 2015, the BYU Cybersecurity Research Lab (CSRL) held its first annual summer camp for Girls aged 14-18. A total of 38 girls attended the week’s activities and workshops. While over 75% of girls indicated they had taken a computing-related class, only 40% reported any significant interest in cybersecurity prior to the summercamp with 10% believing they had some experience in the field. At the conclusion of the camp, 80% of attendees reported a significant interest in the field with 100% of attendees interested in attending a similar event again.

Streamlining The 3d Animation Process, Dylan Hoffman, Kelly Loosli

Journal of Undergraduate Research

I knew from the beginning that this project – centered around improving the collaborative process of making a 3D animated film across several “stages” and made by several artists of different specialties, temperaments, and backgrounds – would be two-fold. The first phase was learning more about the process itself, and how each phase related to another. The second, zoning in on an area that has been a weakness for BYU Animated Films in the past – character effects and cloth simulation. The project evolved much over the course of the year, with far more time and value being placed in …

Understanding The Interaction Between Ulk1 And Atg9 And Autophagy, Ryan Hyatt, Joshua L. Andersen

Journal of Undergraduate Research

Autophagy is an adaptive catabolic process of self-digestion, a process by which the cell recycles aged organelles and other structures. Interestingly, changes in the regulation of autophagy have been linked to infections, cancers, neurodegeneration, aging, and heart disease (Arroyo, Daniela S. et al. 2014). Understanding the mechanisms which control autophagy will aid in better treatment of those diseases, specifically in the development of effective pharmaceuticals.

Dual Species Calcium And Ytterbium Magneto Optical Trap, Alexander Erickson, Scott Bergeson

Journal of Undergraduate Research

One area of particular interest in modern physics research is creating a viable fusion system for sustainable energy. Fusion occurs when a high energy plasma is manipulated in such a way that small atoms collide together, combining to create larger atoms and releasing tremendous amounts of harvestable energy. However, there are many theoretical, mathematical, and practical roadblocks to creating a stable fusion experiment. One practical limitation and one mathematical limitation are as follows: practically, much of the energy used to create a fusion-grade plasma ends up in the kinetic energy of the electrons and is lost to the experiment; mathematically, …

The Mechanism Of Homogeneous Hg-Catalyzed Methane Partial Oxidation, Steven Butler, Daniel Ess

Journal of Undergraduate Research

There is now access to vast amounts of inexpensive natural gas, due in part to shale gas discoveries. Abundant natural gas provides significant motivation to develop methods for methane partial oxidation. One major target for methane oxidation is methanol. Natural gas is principally methane, but also includes significant amounts of ethane and propane. Methanol can be produced from natural gas via high-temperature generation of syngas (mixture of H2 and CO).

Systematic Analysis Of Nonlinearities In Complex Models, Alexander Shumway, Mark Transtrum

Journal of Undergraduate Research

Mathematical models are ubiquitous in science. Many models are nonlinear in the parameters and may have dozens to thousands of parameters and make hundreds to thousands of predictions. Analysis and application of these models is thus theoretically complicated and computationally expensive.

The standard method of model analysis is a model-by-model approach that relies on the intuition of expert researchers. Recent research, however, has shown that many models—known as sloppy models—are statistically similar, despite coming from widely varied fields⁴. This suggests the possibility of developing a theory of modeling in place of relying on expert intuition. Our research …

The Impact Of Snake Creek On The Provo River Watershed Chemistry, Tucker Chapman, Greg Carling

Journal of Undergraduate Research

Snake Creek is a tributary to the Provo River, which is an important water source for over two million people along the Wasatch Front. Arsenic concentrations in Snake Creek exceed the EPA limit of 10 μg/L and mixing water in the Provo River exceed the EPA (recommended level) of 1 μg/L. Snake creek contributes about 20% to the overall flow of the Provo River. This study focused on the probable source of arsenic in snake creek. Hot springs and faults are probable causes for high trace element contamination are were the focus of this study.

Reflectometry Of Aluminum Thin Films In The Vacuum Ultraviolet, Benjamin Smith, R. Steven Turley

Journal of Undergraduate Research

Vacuum Ultraviolet (VUV) is a range of light on the electromagnetic spectrum corresponding to wavelengths from 40 – 280 nm. VUV photons have too much energy to see visibly and are blocked completely by atmosphere. This wavelength range, however, shows promise for applications in space-based exoplanet research telescopes. Specifically, the chemical fingerprints that this light contains can tell us about the composition and formation of exoplanet atmospheres.

Zarahemla Revisited: Neville’S Newest Novel, Matthew Roper, Paul Fields, Larry Bassist

Interpreter: A Journal of Latter-day Saint Faith and Scholarship

This article is the third in a series of three articles responding to the recent assertion by Jonathan Neville that Benjamin Winchester was the anonymous author of three unsigned editorials published in Nauvoo in 1842 in the Times and Seasons. The topic of the unsigned editorials was the possible relationship of archeological discoveries in Central America to places described in the Book of Mormon narrative. The first article shows that, contrary to Neville’s claims, Winchester was not a proponent of a Mesoamerican setting for the Book of Mormon, but rather a hemispheric one. Since this was a view commonly held …

Untangling Scripture From The Philosophies Of Men, Mark Bukowski

Interpreter: A Journal of Latter-day Saint Faith and Scholarship

Terryl Givens’ masterful work Wrestling the Angel takes on the daunting task of examining the history of Christian belief while also examining the worldly philosophies which shaped its scriptural interpretation. As in the biblical story of Jacob’s struggle with the angel, we all must forge our own testimonies while confronting a secular world including godless philosophies. Sometimes testimony wins, and tragically sometimes the world wins and a testimony is lost. In dealing with this intellectual “matter unorganized,” interpretation of the secular philosophy becomes the key. With the right interpretation, philosophies deemed “secular” or “godless” can be seen as helpful and …

A Brighter Future For Mormon Theology: Adam S. Miller’S Future Mormon, Jeff Lindsay

Interpreter: A Journal of Latter-day Saint Faith and Scholarship

Adam S. Miller’s Future Mormon, his collection of “Essays in Mormon Theology,” is one of the most intriguing reads I’ve encountered in LDS studies. It is a book intended to make students of Mormonism, especially those within the Church, challenge lazy assumptions in our theological thinking and rethink our approach to help us build a stronger faith. Some of Miller’s work here will be readily grasped and appreciated by LDS students, while other parts may be more radical or opaque. From my perspective, the gems should make the book a valued addition to any LDS library, in spite of my …
