George Major and Faculty Mentor: Dr. Matthew Linford, Department of Chemistry and Biochemistry Thin Layer Chromatography (TLC) is widely used for performing chemical separations and has been a staple in separation techniques. However, the functionality and effectivity of TLC plates has not changed over the past several decades. Standard TLC plates have a slow developing […]

Alternative Methods for Assessing the Benefit of Geogrid Reinforcement on Base Materials
Jaren Knighton and Dr. W. Spencer Guthrie, Civil and Environmental Engineering Introduction The pavement engineering industry needs a quick, inexpensive laboratory testing method for evaluating the structural benefit that can be expected in the field when geogrid is incorporated in a pavement. Geogrid is typically made of rigid polypropylene with ribs that form openings, called […]
When Science Meets Art: Understanding the Results and . Methods of the American Sagger Process
Jason Palmer and Professor Brian Christensen, Department of Visual Arts Overview The aims and purposes of this ORCA funded research project were two fold; first the funds would be used to renovate a heavily used kiln in the ceramics department to allow for greater atmospheric control, operator’s ease of use, and general safety. Second we […]
An Investigation of Methods for Actuating Robot Arms: Direct vs. Pulley vs. Bowden Cable Actuation Methods
Dallin Swiss and Dr. Mark Colton, Mechanical Engineering Introduction A group of BYU researchers and therapists designed a robot named “Troy” for use in studies to investigate robot-assisted therapy for children with autism [1]. Troy was considered effective and successful but studies suggest that developing a new robot with greater realism and additional capabilities may […]
Evaluation of Methods to Relieve Parental Perceptions of Vaccine-associated Pain and Anxiety in Children: A Pilot Study
Amy Pulsipher and Dr. Beth Luthy, Nursing The development and widespread use of vaccinations is one of the most important public health achievements of the 20th century (Schechter, Zempsky, Cohen, McGrath & McMurtry, 2007). Despite the immeasurable benefits of vaccinations, many parents are still reluctant to vaccinate their children. Multiple studies have reported that the […]
Quasi-maximum Likelihood Methods in Truncated Models
Patrick Turley and Dr. James B. McDonald, Department of Economics Data truncation is the source of econometric problems in many economic datasets. Truncation occurs when all observations below or above a certain threshold are systematically removed or are unavailable. For example, campaign contributions below a certain level are not usually publicly available, so any contribution […]
ANCIENT “GENE-OLOGY” LEADS TO IMPROVEMENTS IN ANCIENT DNA EX· TRACTION METHODS AND PCR AMPLICATION TECHNIQUES
Blake C. Ballif, Microbiology Introduction During the past decade, the development of ancient DNA research has left modern science seemingly on the verge of breaching the barrier between the world we live in and the ancient past. Archaeologists, anthropologists, and molecular biologists alike have become increasingly more aware of the understanding that can be gleaned […]
Comparison of Two Body Composition Measurement Methods: Bod Pod and DEXA
Kenric L. Russell and Dr. Larry Tucker, Physical Education People with excess weight, and especially excess body fat, have an increased risk for many health problems. These problems include heart disease, hypercholesterolemia, hypertension, increased morbidity and mortality from diabetes, and cancer. The National Center for Health Statistics recently reported that 33% of Americans are overweight. […]
Statistical Process Control Methods for Multiple Stream Processes: A Comparative Study
Jared Caleb Christensen and Dr. Scott D. Grimshaw, Statistics The Shewhart control chart is the most common statistical process control (SPC) tool used to determine stability. One fundamental assumption of the Shewhart chart is that the output comes from a single, continuous stream. This implies the monitoring of a single source of variation. Filling machines […]
Fast Simulation Methods For Electrons in a Penning Trap
Brent A. Chipman and Dr. Ross Spencer, Physics and Astronomy The motivation for this work comes from the paper “Parametrically Pumped Electron Oscillators” by J. Tan and G. Gabrielse (1). Tan and Gabrielse describe a number of unexplained behavior exhibited by electrons confined in a parametrically pumped penning trap. In order to gain a better […]
