Mark K. Morris and Dr. Ray Merrill, Health Science Conventional cancer incidence rates reported in the United States represent the number of newly diagnosed cases in a given year divided by the mid-year population for that year (1). Incidence rates have been reported on an annual basis in the United States since 1973, when the […]

Development of Stable Silica Washcoats for Monolithic Substrates
Ethan A. Mastny and Dr. Calvin H. Bartholomew, Chemical Engineering The objective was to develop an efficient procedure for depositing silica washcoats onto cellular, ceramic monoliths while ensuring that the silica maintains its desired properties of surface area and pore structure and is stable against erosion. Catalyst coated ceramic monoliths find application in automotive emissions […]
Metal Ion Analysis for use in Calculation of Apparent Molar Volumes and Apparent Molar Heat Capacities of Copper(II), Nickel(II), and Zinc(II) Nitrates
Eric Merkley and Dr. Earl M. Woolley, Chemistry and Biochemistry Apparent molar heat capacity, Cp,f, and apparent molar volume, Vf, are valuable thermodynamic quantities in the study of solute-solvent interactions and chemical reactions in aqueous solutions. Work in our laboratory1-3 has demonstrated that fixed-cell differential scanning calorimetry (DSC) and vibrating-tube densimetry can provide sensitive and […]
Direct Measurement of Absorption Rates for Laser High-order Harmonics Generated in Helium and Neon
Eric Christensen and Dr. Justin Peatross, Physics and Astronomy Extreme ultraviolet (EUV) light can be generated through the interaction of a high-intensity laser beam with atoms. When an intense laser pulse hits an atom, its outer electron is pulled away from the atom. The electric field of the laser may then pull the electron back […]
Relative Rates of Molecular Evolution in Antarctic Nematodes
TJ Bliss and Dr. Byron J. Adams, Microbiology and Molecular Biology Molecular evolution is defined as any change in the genetic makeup of an organism. Since organisms of the same species and community tend to undergo similar molecular changes, rates of molecular evolution are often measured at the species level. It is well established that […]
Effects of Follicular Dentritic Cells on Recombination Rates of Human Immunodeficiency Virus Type 1
Ericf Burgon and Dr. Greg Burton, Biochemistry Recombination is a major mechanism that generates variation in populations of human immunodeficiency type 1 (HIV-1). Mutations often confer replication advantages, such as drug resistance, which can lead to increased pathogenicity. This project is the first phase of a larger projected intended to study the effects of follicular […]
Does Addition of the SNARE protein SNAP-25 to Syntaxin 1A Enhance Fusion Rates of Modified Synaptic Vesicles in a System Containing the Minimum Vesicle Fusion Machinery?
Jeremy Curtis and Dr. Dixon Woodbury, Physiology and Developmental Biology The original intent of my project was to compare the fusion rates of synaptic vesicles to a syntaxin artificial membrane with and without SNAP-25. Recent research has shown that modified synaptic vesicles may fuse to a syntaxin-only bilayer . Prior to this, the major dogma […]
RATES OF CARBON AND NITROGEN STABLE ISOTOPE TURNOVER IN FIN TISSUES OF Gambusia affinis
Michael Bingham and Dr. Jeff Bullock Abstract The principle objectives of this research analysis were to determine the uptake and turnover rates of carbon and nitrogen stable isotopes in fish and to establish if this isotope verification procedure is possible by testing tissue samples of their fins. This investigation is separated into two main experiments: […]
Vanadium Dioxide Deposited Substrates for Thermochromic Applications
S. Andrew Ning and Dr. David Allred, Physics and Astronomy As the technology was readily available here at BYU, we decided to make our own electrochromic material to meet our specifications. After a literature review we found a study done by Wang et al. [1] which suggests a preparation method using a thin film of […]
A Comparison of Growth Rates in Premature Infants in Tucamàn, Argentina and the United States: A Secondary Data Analysis
Emily Sears and Professor Joann Abegglen, College of Nursing Extrauterine growth, or growth outside the womb following birth, is a serious challenge and concern in premature neonates. Preterm infants have low birth weights simply because they have not reached full growth and development at the time of birth. In addition to prematurity itself, preterm infants can […]
