Conner Earl, Brigham Young University Engineering The emerging field of Cell-free protein synthesis enables the efficient production of complex proteins for a number of exciting applications such as medicines that better interact with the body, vaccines, antibodies, and renewable, sustainable biocatalysts. However, progress is hampered by high costs and low yields of necessary proteins. This project is designed to improve protein yields and drive down costs by studying techniques of optimization of protein yields in Cell-Free protein synthesis. Our main area of focus is the inhibition of naturally occurring ribonucleases (RNAses) which are enzymes that degrade essential elements for protein synthesis- specifically, the mRNA used to transcribe protien. One of the techniques we intend to use for inhibition of these RNAses is by complexing the RNAse with an appropriate RNAse inhibitor protein thus limiting or eliminating its function of degrading mRNA. The aims of this research project is to: (1) Identify appropriate RNAse inhibitors (2) Design and synthesize inhibitor genes (3) Express, purify and assay RNAse inhibitors (4) Improve Cell-free protein synthesis yields utilizing RNAse inhibitors for analysis of activity and effectiveness as well as the enhancement of cell-free protein synthesis yields. Accomplishing these goals will result in more efficient systems and more accurate analysis that may lead to cheaper, more readily available vaccines and pharmaceuticals produced through Cell-free protein synthesis.

Theo Stoddard-Bennett and Steven Christiansen, Brigham Young University Engineering Damage to the human retina is often irreversible and so currently there are no established treatments of diseases such as dry age related macular degeneration (AMD). Dry AMD results in a loss of sight because of cell death in the macula, a centralized part of the retina which contains a high concentration of photoreceptor cells. One possible treatment would be to limit the rate of cell death within the macula, however this is not a comprehensive solution. Rather, regeneration of the photoreceptors within the retina is necessary to restore sight. In current research, Müller glia cells, a major glial component of the retina, can potentially be used as sources for photoreceptor regeneration in order to combat dry AMD due to their homeostatic regulation of retinal injury. Directed reprogramming would occur through a five step process. The Müller glia would need to undergo de-differentiation to Müller glia-derived progenitor cells (MGPCs), proliferation of MGPCs, migration of MGPCs, neuronal differentiation, and integration in order to generate retinal neurons. Müller cells can be isolated and cultured by dissociating retinal tissue in optimal media. Here we present the dissection and dissociation of rat retinal tissue to obtain purified proliferating Müller cell cultures. Our lab has tracked and modelled the rates of proliferation and phenotypically characterized the stages of proliferation. Using immunofluorescence and PCR tests to confirm purity, we will then expect to run a series of assays to identify growth factors, Wnt signals and cytokines to test the effects of retinal extracellular matrix proteins on Müller cell de-differentiation to MGPCs. The focus of our current research is the identification of reprogramming mechanisms that may possess beneficial data leading to both unique strategies for promoting retinal regeneration in mammals and clinical applications for those living with dry AMD.

Dan Barfuss, Brigham Young University Engineering Shale oil has long been seen as a source of energy that can be incorporated into existing infrastructure. It consists of kerogen (or organic matrix) bound to inorganic rock. This kerogen can be released as an oil-like substance by heating it up to high temperatures without the presence of oxygen (i.e., pyrolysis). Due to advances in NMR (Nuclear Magnetic Resonance) we were able to make an accurate structural based model that can predict the relative tar and light gas yields[1]. We modified the Chemical Percolation Devolatilization Model (CPD) of coal to fit with the more aliphatic nature of oil shale. The CPD model describes the aromatic regions as clusters and aliphatic regions as bridges. As these bridges are broken the model releases groups of clusters that will form tar. In coal the bridge breaking gives off light gases, whereas in shale oil the bridges are much heavier and mostly form tar. We built two models that accounted for this. We also used the composition of the tar and the gas found by Fletcher et. al. [2] to predict what elements would be left and the aromaticity of the carbons. We found that throughout the reaction new aromatic regions were formed. With information from this model,- we are able to better predict the products of oil shale pyrolysis, and describe what happens chemically.

Nandini Deo, University of Utah Engineering Air quality in the United States has come under scrutiny in recent years. Many pollutants are trapped in the air we breathe in the form of photochemical smog. The aim of this research is to aid the breakdown of these pollutants. Peroxyacetyl Nitrate (PAN) is a predominant smog species; the research conducted aims to decompose this molecule and capture the resulting particles using the photocatalytic properties of Titanium Dioxide Nano tubes. The research conducted thus far has focused on the following questions:What molecules does the thermal decomposition of PAN produce? Is there a metal substrate to attach to TiO2 Nano-materials that aids the breakdown of PAN and its decomposition products? Can a sustainable process/device be identified to functionalize these materials? Literature research shows that PAN thermally decomposes into CO_2, NO_2, methyl nitrate, and formaldehyde. Methyl Nitrate and CO_2 may be eliminated using specific experimental conditions. Hence, it can be determined that the substrate attached to TiO2 must decompose PAN, NO_2 and formaldehyde. Using the molecular modeling programs Avogadro and MOPAC, 50 metals were optimized in relation to Formaldehyde, NO_2, and PAN. To find each metal’s reactivity to each target compound, HOMO/LUMO (Highest Occupied Molecular Orbital/Lowest Occupied Molecular Orbital) energies were calculated and used to find the common reactive metals between the target compounds: Cobalt, Silver, Iridium, and Niobium. To test whether the most complex product of the PAN decomposition (Formaldehyde) will break down, a device was created using a 3-D printer and Cobalt functionalized nanotubes. Pure formaldehyde, a blank sample (no tubes), and a sample with functionalized tubes were run through the device in the form of vapor, in front of a solar simulator. The captured vapor’s GC/MS results show an almost complete breakdown of Formaldehyde with the use of the device containing the functionalized tubes.

Takami Kowalski, Warren Robison, Anton Bowden, and Brian Jensen, Brigham Young University Engineering Using a coronary stent to expand a blocked blood vessel as a way to treat coronary heart disease has proved effective in the past. However, there are risks, such as thrombosis, that are a natural side effect of inserting a foreign object into the body. Creating a stent out of a hemocompatible material such as carbon-infiltrated carbon nanotubes could potentially resolve these issues and also make unnecessary treatments such as dual antiplatelet therapy as a way of decreasing the risk of adverse side effects. Previous research done in this lab has shown that carbon-infiltrated carbon nanotubes can be grown in a pattern defined by photolithography on a planar surface. The present work demonstrates preliminary results from patterning a flat, flexible substrate and rolling it into a cylindrical shape before growing carbon-infiltrated carbon nanotubes as a way to fabricate cylindrical stents, fulfilling all necessary specifications for a stent with the added benefit of hemocompatibility. We also demonstrate growth on curved substrates and explore process parameters for achieving good-quality CNT forests.

Steven Stanley, Brigham Young University Engineering The genetic code has long been restricted to a set of 20 fundamental building blocks called amino acids. Recent research has expanded the genetic code through unnatural amino acids (uAA), thus adding enormous possibilities to the potential chemistries of proteins. Because nature is highly selective in the protein translation process, it has proven extremely difficult to successfully insert multiple uAAs simultaneously. The incorporation of an uAA with in vitro methods typically relies on the use of the amber stop codon as a mutated insertion site. A stop codon placed at the middle of a gene can code for either the uAA or termination, thus, protein synthesis may often terminate prematurely instead of inserting the desired uAA. This inefficiency inhibits the possibility of inserting multiple uAAs simultaneously. We propose a novel method that will allow for multiple uAAs to be inserted simultaneously. Our method involves isolating a minimal set of tRNA for in vitro protein synthesis, allowing for uAA insertion to occur at codons other than the amber stop codon. My work has focused on the production of 4 versions of uAA-tRNA synthetase, a protein that charges tRNA with the uAA. We are currently growing these 4 different proteins in bulk and testing their activity. We will test them for compatibility, confirming that they do not interfere with one another and other synthetases native to our in vitro protein synthesis system. These uAA-tRNA synthetases, in conjunction with specialized tRNA, will provide the basis to efficiently incorporate multiple uAA simultaneously. The success of this project will have many practical applications ranging from new therapeutics to new methods of medical diagnosis.

James Newton, Scott Anjewierden, and Sasha Luks-Morgan, University of Utah Engineering Oxytocin (OXT), a neuromodulatory peptide produced by the hypothalamus, is involved in a variety of physiological and behavioral phenomena. Exogenous OXT and drugs that mimic OXT signaling are potential treatments of a number of neurological disorders. The canonical mechanisms of OXT function are neuroendocrine in nature, as the peptide is released into circulation through the neurohypophysis. However, OXT has also been shown to exert some of its effects through direct synaptic release within the central nervous system. Using the larval zebrafish as a model, we seek to identify targets of these directly projecting OXT neurons and study what role they play in the modulation of behavior. Critical to this analysis are computer programs which enable precise quantification of anxiety, social behavior, and reward learning. Our custom-written software automatically identifies and tracks free- swimming fish, using measured positions over time to evaluate behavior in a variety of paradigms. In combination with molecular, cellular, and optogenetic manipulation of OXT networks, this project will allow a fuller understanding of the relationship between these neurons and behavior.

Carlton Reininger and John Salmon, Brigham Young University Engineering Electric Vehicles (EV) are a rising alternative to standard combustion vehicles because of their energy cost savings and reduced carbon emissions. However, EVs come with limitations such as limited driving range and potentially long recharge times. The purpose of this study is to determine the feasibility of implementing an electric vehicle system into an urban environment. Using data provided by the New York City Taxi and Limousine Commission, models are developed and generated to simulate driver shifts and analyze system level impacts from EVs on driver behavior. The models evaluate the number of charge events over the course of a shift and calculate the potential revenue lost to missed fares during charge intervals. Across the system, the results indicate that for a majority of NYC taxi drivers, EVs can be implemented without significant changes in driver behavior, while providing an economic and environmental advantage over current combustion vehicles. These preliminary findings can be used to support implementing such a system in urban environments and these models could be used as a template toward analyzing EV taxi potential in other cities.

Scott Anjewierden, James Newton and Joshua Barrios, University of Utah Engineering Organisms in their natural environment are constantly presented with sensory stimuli. These stimuli must be filtered by the brain to select an appropriate behavioral response. A significant example of this filtering process is audiomotor prepulse inhibition (PPI). In PPI, the startle response to a loud noise is suppressed by a preceding stimulus of lower intensity. This ability to optimize behavior in response to environmental context is an essential brain function. Defects in PPI are associated with neurological disorders such as obsessive- compulsive disorder, Tourette syndrome, and schizophrenia. This project demonstrates the development of new software to analyze swim kinematics in a restrained, larval zebrafish model of PPI. Our programs automatically extract several kinematic parameters from image sequences of behaving animals and use them to classify behavior into one of three, stereotyped categories. Correct classification is reported in 96.32% of trials (n = 162). This automated analysis will now permit a more robust study of PPI in these animals, where the brain’s experimental accessibility will allow us to discover the cellular bases of sensory filtering.

Erika Longino, University of Utah Education DesignbuildBLUFF is a development program wherein graduate architecture students apply custom designing and construction skills to make homes for Navajo families and individuals in need. 39% of the Utah reservation is under the poverty line and the whole Colorado Plateau is in an ecologically vulnerable position. There is clear evidence that water tables are dropping and native biodiversity is suffering because of anthropogenic climate change. Therefore, the human communities in the region are especially needful of proper infrastructure for sustainable development. DesignbuildBLUFF provides diverse services to many groups. The aim of this investigation is to map a framework for sustainable expansion and overall systematic improvement. The investigation will eventually produce a document outlining the inputs and outputs of DesignbuildBLUFF, environmentally and socially. Ecological components like soil quality, solar potential, rainfall, and plant inventory are noted and analyzed quantitatively. Social impacts are gathered using interviews and census data. The data is pulled together in a cohesive, aesthetic map and used to plan DesignbuildBLUFF’s trajectory. The document will provide a clear framework for acknowledging and eliminating unnecessary features, reducing the ecological footprint of the organization, and improving important social relations. This document is not a definitive “master plan”, rather it provides the necessary data and suggestions for growth that take into account whole systems thinking.

Shayla Miller, Dixie State University Education My research focuses on the positive side effects of using models and representations to facilitate student learning in the classroom. The science lesson was taught and recorded to a class of thirty students. The students made visual models/representations of their knowledge about ecosystems from the lesson taught. Test scores were improved, and the information was proven to stay in long term memory according to end of level testing.

Ryan Graham and Bryson Ensign, Brigham Young University Agriculture Agastache is an aromatic flowering plant closely related to the mint family. Most species are 0.5-3m tall with toothededged leaves covering the stem. Agastache is commonly found in landscaping, but can become quite noxious because of the abundance of seed produced in each flower head. Here we used an antimitotic agent, trifluralin, to induce polyploidy in Agastache seedlings with the foresight of creating a sterile version of the plant. Putative polyploids were checked for chromosomal content via flow cytometry. Our data show that trifluralin treatment is a potentially successful method for inducing polyploidy in Agastache. Further, among the positively identified polyploids, we have noticed suggestive patterns of sterility. However, further research needs to be conducted to confirm this finding. For now, we are able to present an effective method for inducing polyploidy in Agastache and, potentially, other plant species.

Carrie Draney and Amanda Hobson, Brigham Young University Agriculture Decreased β-cell mass is a hallmark of type 1 and type 2 diabetes. The use of islet transplantation as a diabetes therapy is hampered by the relative paucity of transplant ready islets. Greater understanding of the proliferative pathways controlling islet proliferation may be harnessed to increase functional β-cell mass through transplantation or by enhanced growth of endogenous β-cells. We have shown that the β-cell transcription factor Nkx6.1 induces β-cell proliferation by upregulating the orphan nuclear hormone receptors Nr4a1 and Nr4a3. Using expression analysis to elucidate the Nkx6.1 independent mechanism by which Nr4a1 and Nr4a3 induce β-cell proliferation, we demonstrated that cyclin-dependent kinase 5 regulatory subunit 1 (Cdk5r1) is upregulated by Nr4a1 and Nr4a3 and not Nkx6.1. Adenovirus mediated overexpression of Cdk5r1 is sufficient to induce proliferation in primary rat islets. The observed proliferation is primarily in β-cells. Glucose stimulated insulin secretion is maintained with Cdk5r1 overexpression. The Cdk5 inhibitor, roscovitine, blocks islet proliferation, suggesting that Nr4a mediated β-cell proliferation is a kinase dependent event. Overexpression of Cdk5r1 results in pRb phosphorylation, which is inhibited by roscovitine treatment. These data demonstrate that activation of the Cdk5 complex is sufficient to induce β-cell proliferation while maintaining glucose stimulated insulin secretion.

Samantha Beck, Utah Valley University Agriculture Capsicum annuum (hot chili pepper) originated in Central and South America but due to its many economically important characteristics this species is now used all throughout the world in many varied applications. Encompassing many diverse varieties, each with distinctive beneficial characteristics such as spiciness (pungency), this species has become a focal point for research. The “pungency” is due to its secondary metabolites called Capasaicinoids (Capsaicin and Dihydrocapsaicin among others); making these varieties useful in food products and the pharmaceutical industry. Metabolites from C. annuum have shown to be effective against inflammation, pain, psoriasis, high cholesterol, atherosclerosis and other ailments. Evidence also has shown that these secondary metabolites (Capasaicinoids) trigger cell suicide in prostate cancer cell lines. Micropropagation of this important species is crucial for breeding programs, analysis of secondary metabolites, propagation at industrial level and development of research in different fields. This research evaluates the effects of different plant growth regulators on the embryogenesis and organogenesis of three varieties of pepper: Jalapeno, Cayenne and Thai. Reliable organogenesis and embryogenesis methods in these varieties have not been published. Our results show that callus growth was stimulated in these varieties with MS media amended with 5μM BAP (6-Benzylaminopurine) and 2.5μM 2,4-D (2,4-Dichlorophenoxyacetic). The response to fruit extract on callus growth was evaluated; the Jalapeno variety responded positively to the addition of fruit extract whereas the Thai variety did not show induction of callus. Additional effects of different concentrations of growth regulators and different medium on embryogenesis and organogenesis will be described. This research provides valuable information that can be used by researchers and commercial propagators.

Wonjin Kim, Weber State University Business The trade balance of a country, calculated as total exports minus total imports, measures the impact of foreign trade on the demand for that country’s output. It is proposed that there are generally three key determinants of trade balance, e.g., the real exchange rate, home disposable income, and foreign disposable income. In principle, as the home country’s real exchange rate depreciates (rises), the country is expected to export more and import less. An increase in home country’s income is expected to increase imports and generate a decrease in home country’s trade balance. On the other hand, an increase in foreign income is expected to raise the home country’s trade balance. This paper makes an attempt to explore whether the expected relationships between trade balance, home income, foreign income and real exchange rate holds. The United States is considered the home country and Japan is considered the foreign country in this study. The reason for using Japan as a foreign country is twofold: first data availability and second, Japan is one of the largest trade partner of the United States. We use quarterly data to conduct our study. The sample period spans from 1994 to 2012. We hypothesize that the real exchange rate has a positive relationship with trade balance. Also, we hypothesize that the U.S. income has a negative and Japan’s income has a positive effect on the trade balance of the United States. To test our hypothesis we run a multiple regression. The dependent variable in our regression is trade balance. The independent variables are home and foreign incomes and real exchange rate.

Josh Groves, Utah Valley University Business This study will discuss the contributions of eye-tracking data in testing first-time viewers of identified professional salespeople. Participants will view the professional portraits of two individuals, a male and female. With the results we hope to show that eye-movement data supplements what users verbally report in their reactions to an individual. In particular, eye-tracking data will reveal which aspects of the person receive more visual attention and in what order they are viewed. As eye-tracking systems have become more sophisticated and affordable, there has been an increasing interest in the use of eye-tracking within the first impression domain (Byrne, Anderson, Douglass, and Matessa, 1999; Kotval and Goldberg, 1998; and Hornof and Halverson, 2003). Despite increased research in this area, it is still not entirely clear exactly how much eye-movement contributes to the viewer’s evaluation of another individual. As part of a comparative test between two professionals’ images, participant eye-movements will be recorded during the initial introduction to the image. The eye-tracking data will be examined to gain additional insight into how users view that individual and what elements attract their attention. Additionally, respondents will be asked to provide their perceptions of five personality dimensions of the two individuals.

Brock Griffith and David Lewis, Dixie State University Business In the past, some accounting researchers have criticized university accounting education programs. In their view, there is a gap between accounting education and practice. According to Sunder (2007), “The accounting curriculums of most business schools are full of theories that have less practical relevance.” The aim of this research is to identify the knowledge of subjects and skills needed for a relevant university accounting program. The views of over 200 professional accountants were sought and data collected using a questionnaire. In addition, several follow-up interviews and discussions were conducted with participants of the study. The findings suggest that the traditional accounting subjects are very important for a relevant accounting education. However, many professionals believe that certain aspects of accounting education are needed but currently the accounting education is not adequately meeting those needs.This paper helps to bridge the gap between academic study in accounting and a career in the professional practices. The results of the research will assist accounting educators in delivering work-ready graduates who will assist in meeting the needs of employers in the accounting profession.

Jennifer Melvin and Wendy Schatzberg, Dixie State University Physical Sciences The general chemistry laboratory can be a dangerous place, and the possible danger is amplified by the fact that general chemistry is frequently a student’s first chemistry laboratory experience. College students come from a variety of backgrounds with only some having had chemistry in high school, and therefore many students will not know beforehand what kind of precautions to take or what kind of action to take in case of an accident in the lab. Safety information is given briefly at the beginning of the semester, but the efficacy of this is uncertain. An online survey was conducted to gauge first- and second-semester general chemistry students’ knowledge about chemistry laboratory safety and the data gathered was analyzed. This survey was conducted at two secondary schools in two different countries. Statistical analysis will be presented. Results will allow discernment of misconceptions held by students over two semesters and between countries, and conclusions can be made about the effectiveness of current laboratory safety instruction methods.

Brett Barton, Dixie State University Physical Sciences Dissolution using ionic liquids has been shown to be an efficient analytical method of dissolving keratin fibers. Using wool and hoof material from livestock, chloride-based ionic liquids were used to break down the hydrogen bonds important for keratin structure, making the extraction of constituent material much easier. Efficient methods of extraction allow for small samples to be analyzed while still providing high yields; efficient dissolution of keratin in a small sample size will be utilized to prevent any harmful effects on the animals. Ionic liquids are nondestructive solvents which allow for the safe extraction of organic substances. Denaturing keratin would help in the process of identifying any constituent radioactive materials. Efficient identification of radioactive material in livestock is crucial for maintaining health and quality of life.

Tim Beach, Utah State University Physical Sciences Successful management of the arid West requires a basic knowledge of available water resources, withdrawals, and existing management efforts. Utah, the second driest state in the country, is continuing its efforts to restore impaired water systems and teach the next generation to conserve water. Because of a fast-growing population, the diversity of Utah’s landscape, and strict regulations that govern water throughout the state, understanding the region’s current water condition can be difficult. Historically, the majority of this information has been stored in databases, represented by only numbers and statistics. In an effort to better conceptualize this data and increase the spatial understanding of Utah’s water, a set of maps have been produced. These maps were created using ESRI’s ArcMap software and Adobe Illustrator. Included are major lakes and rivers, average annual precipitation, average annual streamflow, total urban withdrawals per county, total agricultural withdrawals per county, and water management. Viewing visual representations of this information in multiple maps can aid in creating spatial inferences, and raise additional questions regarding aquatic restoration and management throughout the state. This set of maps can also be used to supplement physical science education at all school levels. Future work includes distributing these maps as posters to schools and water managers, as well making it a resource for teachers via websites and fact sheets.

Melinda Hurlbut, Dixie State University Physical Sciences A newly discovered plant fossil locality in the Chinle Formation (Upper Triassic) in Washington County broadens the distribution of known Late Triassic plant fossil localities to include southwestern Utah. Previously reported plant localities in the Chinle Formation are known from southeastern Utah, Arizona, New Mexico, and equivalent strata from the Dockum Group in Texas. The majority of the known plant fossil localities are from higher stratigraphic units of the Chinle Formation. However, the new Washington County locality is from the older, basal unit, the Shinarump Member. The plant fossils identified from the new locality include fronds of the fern Phlebopteris sp., fertile leaves of the fern Cynepteris sp., and leaves of the bennettitalean Zamites sp. Undetermined species of conifers are represented by a partial branch and a three- dimensionally preserved cone containing well preserved seeds. The diversity of species found at the Washington County plant fossil locality correlates with other known floral assemblages from the Chinle Formation, suggesting general homogeneity of Chinle Formation floras. These plant fossil assemblages support interpretations of basal Chinle Formation paleoclimates as humid and warm.

Eric Johnson, University of Utah Physical Sciences The ability to reduce O2 in mild conditions holds many important implications such as: use as an economical fuel cell, pharmaceutical synthesis, biomass degradation and conversion of small molecules to fuels. We are building the [M(μ-OH) (oxapyme)M(H2O)]+ molecules and symmetrical counterparts for use in O2 reduction reactions (M = Cobalt, Nickel, Iron). The precursors to the [M(μ-OH)(oxapyme)M(H2O)]+ have been synthesized as follows. 2-[5-(2-Nitro-phnyl)-[1,3,4]oxadiazol- 2-yl]-phenylamine serves as the backbone of the complex, allowing for two distinct ligands to be attached to each side. Initial yields for this synthesis averaged at 6%. To be able to complete the synthesis this needed to be significantly raised. The literature procedure was modified in various ways until new reaction conditions were found that allowed for 40% yield. Other precursors include 2,2’-(1,3,4)Oxadiazole-2,5-diyl-bis-aniline which also serves as a ligand backbone but differs in that it allows for preparation of a symmetrical ligand have been synthesized with a 51% yield. The first ligand Bis-pyridine-2-ylmethyl-amino has been produced with a 60% yield. The second ligand Methyl-pyridine-2-ylmethyl-amino has been synthesized with an approximate yield of 75%. These yields are high enough to finish the synthesis of the ligand and subsequently coordinate the metals. Upon completion, the electrochemical properties of the compounds that differ in the metal composition and the ligand (symmetrical versus asymmetrical) will be determined using studies such as cyclic voltammetry. Once the metal and ligand that are most apt at oxygen reduction is determined, more advanced studies will be undertaken to identify the reaction mechanism and intermediates.

Kyle Marcus, Cami McKellar, Riley Pearce, Shay Beck, and Zenja Draca, Dixie State University Physical Sciences Invasive marine and freshwater species have a detrimental impact on aquatic ecosystems and are easily transferred between bodies of water as a result of unregulated settlement and attachment to commercial and recreational watercraft. This results in infestation of waterways and disruption of native organisms throughout an ecosystem. The quagga mussel (Dreissena rostriformis bugensis) is one example of such invasive species that has called for a focus on cross-contamination prevention. The goal is to use aquatic paint suitable for watercraft that prevents the settlement and/or attachment of various aquatic species such as algae, snails (Physa sp.), anemones (Aiptasia sp.), and quagga mussels. The paint is integrated with newly developed surfactants that act as an inhibitor to the adherence ability of invasive aquatic species. The surfactants are added to provide a barrier between the paint surface and the organisms creating an undesirable surface area for the organisms to attach. This barrier disrupts the specific naturally occurring chemical and physical processes that allow organisms to adhere to surfaces. The most innovative characteristic of the surfactant-based paint is its effectiveness on adherence inhibition without degradation, dissociation, or toxicity to the environment. Preventing adherence of invasive organisms to surfaces could have significant positive effects on the efficiency and cost of operations in marine environments and waterways.

Mattie Jones, Dixie State University Physical Sciences Current techniques for isolating components of samples found at crime scenes by their unique chemical properties are lengthy and often destroy important forensic evidence. New methods aimed at forensic analysis of sensitive, minute samples are critical to the intelligence community. In particular, successful extraction of dyes from materials found at crime scenes will provide innumerable benefits for matching, identifying, and finding origins of these materials and dyes. Ionic liquids possess the necessary chemical properties to ensure efficient extractions while maintaining the forensic signatures of the original materials. Ionic liquids, which are organic salts that are room temperature, provide a versatile solvent to achieve single-component extraction-separation-identification of forensic analytes. Following extraction, successful identification by infrared, absorption, and fluorescence spectroscopy has provided evidence of preserved quality and complete separation of material and dye. This novel approach to forensic analysis is advantageous particularly when sample sizes are extremely limited, but it can be readily scaled to larger applications. Developing a simple and affordable method of achieving specific molecular interactions provides a solution for often unidentifiable evidence in crimes. Harnessing the versatility of ionic liquids in a high-yielding recovery and efficient single-pot methods will enhance forensic abilities for the intelligence community and forensic investigators.

Madeline Parson, Travis Bulloch, and Tyler Argyle, Southern Utah University Physical Sciences Lipid bilayers have many important purposes in living cells. A lipid bilayer forms a barrier which separates the fluid inside the cell from the fluid surrounding the cell. The arrangement of components within cell membranes can be extremely important, particularly in cell communications. For example, when our immune system attacks certain pathogens, it recognizes them by specific proteins in the inner and outer regions. This can be thought of as forming a “bull’s-eye” shape. The ability to generate such patterns in bilayers might see applications in many areas of biology. Our goal is to take an initially un-patterned supported lipid bilayer (model cell membrane) and use magnetic tweezers as a delivery system to generate patterns. We hope to show pattern formation using fluorescent-labeled lipids within our bilayer. In the past, we have used streptavidin and biotinylated lipids with Oregon Green. Currently, we are pursuing a fluorescein/anti-fluorescein system that has been yielding much more promising results. We are currently using a fluorescent microscope to confirm that patterns are forming within the bilayer.

Michael Kutschke and Niccolo Fiorentino University of Utah Measurements of joint angles, moments, and forces can be sensitive to positional changes in the center of a joint. Due to its deep location, the hip joint center (HJC) can be difficult to determine. Regression equations and functional methods use skin markers and are commonly used to measure the HJC, yet introduce sources of error such as bony landmark identification, soft tissue artifact, and system resolution. Additionally, the accuracy of said methods cannot be established in-vivo without a reference standard. The purpose of this study was to implement a dual fluoroscopy (DF) and model-based tracking technique to quantify the subject-specific HJC position in-vivo. This reference standard (DF-HJC) was then compared to the HJC defined by regression equations (CODA) and a functional method (FHJC) using skin markers. Five subjects with normal hip anatomy provided informed consent to participate in this IRB approved study. A gait marker set was applied to the subject’s skin. The subject performed various activities involving the inferior limb while a 10-camera Vicon system measured the position of the skin markers. From these data, the CODA and FHJCs were identified. Simultaneously, the hip was visualized using a DF system, and the DF-HJC was identified using model-based tracking. The DF-HJC was then transformed to the Vicon coordinate system for comparison with the CODA and FHJCs. The average Euclidean distance (and standard deviation) for the five subjects from the DF-HJC was 2.0 (0.6) cm for CODA and 1.3 (0.4) cm for the FHJC. To our knowledge this is the first study to use DF and model-based tracking to measure the in-vivo position of the HJC. This technique affords greater accuracy in determining subject-specific bone geometry and visualization of deep hip anatomy, thus may be considered a reference standard for identifying the HJC.

Austin Hernandez, Snow College Social and Behavioral Sciences Student’s study habits are always a matter of concern for both instructors and students themselves. Often times when students are learning a new subject the information the receive about studying centers around how they should study for “that class.” Research has also shown that students regularly overestimate their academic ability. The current research examines what happens if student in introductory courses are given strategy sheets which asks them to examine their study efforts and metacognitive strategies in preparation for the exam. This focuses not on the content, but the process that students use to prepare. The data collected from the students will be analyzed in comparison to their performance on subsequent exams to see if the focus on metacognition can effect a positive result on future exams.

Dakota Wilson, Snow College Social and Behavioral Sciences Ambiguity in language throughout history has always caused problems. In every field there are instances where words mean different things to different people. There seems to be more and more instances today where there is ambiguity in romantic relationship terminology and it is causing confusion and dissatisfaction. In the beginning of the 20th century words like “calling” or “going steady” were popular to describe romantic relationships whereas today “hooking up” and “hanging out” are the dominant terms. Although there have been studies that are very similar to this subject, there is little to no research exactly like it. This study has been made to assess what terminology is being used today to describe relationship terminology, why it has changed over (generational and cultural influences), and how these changes affect the satisfaction of the relationship. Methodology comprised creating a survey, a portion of which was taken from pre-validated tools such as the MSI-R to assess relationship satisfaction. Other portions included basic demographic information, current relationship terminology used, short answer where the participants were asked to describe situations in which they would use particular terms now and in middle school, in which social situations they would use certain terminology, and domains as to what each relationship term entailed in regards to behavior (these were based off of the categories in the MSI-R). The last section asked about terminology that was used in the participants youth to avoid disapproval of cultural or religious leaders if an exclusive relationship was unacceptable but was occurring regardless. Results are in the process of being analyzed.

Clair Talley and Melissa Benavides, Snow College Current research done by Susan Sprecher and Sandra Metts (1989, 1999) discusses the presence of romantic ideals and their effect on the quality of relationships. While this research focused mainly on committed relationships of college-aged students, it did not investigate the influence of these love beliefs on their sexual relationship progression. Other research that does look at why students have sex suggests that it is seen as a right of passage, a gift, a stigma, and even a means by which students can alter their mood.

Jamie Slade, Utah Valley University Health Electronic cigarettes (e-cigarettes) are gaining in popularity. Unfortunately, this increase is occurring at a time when we lack a definitive understanding of the health hazards. It is important for professionals to understand e-cigarette users’ experiences and satisfaction with the devices in order to determine what may entice users to begin and continue using these devices.

Daisha L. Cummins, Kodey Meyers, and Breanna E. Studenka, Utah State University Health Children with Autism Spectrum Disorder (ASD) exhibit rigidity of motor plans and difficulties planning and executing movements (Eigsti et al., 2013). Those with ASD may also have difficulty formulating new or switching between different motor plans. In typically developing individuals, sequential actions exhibit hysteresis, a phenomenon where a specific motor plan is influenced by recent, similar motor actions. We sought to determine if hysteresis was stronger in children with ASD. A rotation motor task measured the rigidity of motor planning (hysteresis) of five ASD children, and 5 control participants. A stick was placed in one of 24 different orientations around a circle. The researcher moved the stick counterclockwise or clockwise in subsequent trials. A participant grasped the stick and returned it to the home position. Researchers measured the position at which the child switched from a thumb up to a thumb down grasp in each direction. The peak counterclockwise switch occurred later for children with ASD. The grasp also changed less frequently for the ASD than for the control group. Our results suggest that changing a grasp was more costly than being comfortable, and that hysteresis was more prevalent in children with ASD than in the control group.

Abigail Harris, Brigham Young University Health Purpose:

Tianne Pierce, Utah Valley University Health Since Mario and Zelda (Nintendo video games), video interactive games have been a favorite babysitter for the past two generations of children, simulation is no stranger to this population. Portions of this population became nursing students. Simulation in health care is second to none in the ‘hands on’ teaching of skills; thus, it would be the natural order of things to include interactive figures and scenario during teaching and learning in nursing. Utah Valley University’s nursing department employs the use of human simulators in the delivery of content to the students. It is no surprise that these students relate well to simulation in the classrooms. The purpose of the research study will be to compare students’ responses to learning in a teaching environment void of simulation vs. a teaching environment which uses simulation. Although simulation has long been used in aviation and the military, it has become more integrated in the health care profession over the last 20 years. These study results were congruent with national and international landmark studies where the use of simulation in nursing has been supported by the world of healthcare.

John Rossi, Julie Valentine, Leslie Miles, Linda Maybe, and Julie Melini, Brigham Young University Health The purpose of this study is to explore the effects of sexual assault on memory and consciousness in 314 victims in a Mountain West community using retrospective chart review. Altered mental awareness and/or loss of consciousness during a sexual assault are widely unexplored phenomena. A majority of assaulted individuals experience a varying degree of loss of consciousness during an assault – resulting in memory loss and conflicting evidentiary reports creating challenges during an investigation and prosecution. Statements written by a forensic nurse based on patients’ telling of the sexual assault (analyzed in Nvivo10) were placed within the following categories: memory loss; decreased feelings of mental alertness or awareness; symptoms of tonic immobility; detachment from self, environments and/or situation; reports full loss of consciousness; and/or awoke to assault. Quantitative data from patients’ answers to questions related to their memory of the nature of the assault was analyzed through descriptive statistics in SPSS, resulting in the following statistics: 58.3% reported having a loss of consciousness or awareness, 54.2% reported “unknown” to 1 or more questions about the nature of the assault, 37.8% reported “unknown” to 4 or more questions, 17.3% reported “unknown” to all questions. Additionally, a Chi square test for independence found patients with memory loss/altered consciousness were associated with the following variables: patients with mental illness and/ or use of psychotropic medications (p=0.025) and use of alcohol prior to assault (p=0.000). Medical teams, law enforcement, and judicial representatives must understand the impediments associated with a victim suffering from altered mental status caused by neurobiological and psychophysical effects of sexual trauma; thus, creating an atmosphere that avoids re- traumatizing a patient and providing for optimal care. This research will supplement other studies focusing on neurobiology/sexual assault trauma and foster greater understanding of the effects of sexual assault on memory and consciousness.

Kalene Mears, Brigham Young University Health The purpose of this project is to compile a learning history for a hospital unit, documenting patterns of past adaptation within a clinical microsystem that can be magnified to help the system continue to improve. The goal in healthcare is to create an adaptable system, where changes are continuously made as problems are identified to prevent harm from care. Through a learning history, a hospital unit can identify how they have already solved problems in the past and identify patterns of adaptation that can be replicated to increase reliability within the organization. This project has the potential to help a hospital unit improve its reliability in providing quality patient care and reduce preventable patient harm. To obtain the information about the unit’s history, key team members will be interviewed using an appreciative approach to identify strengths and patterns of successful adaptation. Interviews will highlight positive features of this team to foster feelings of success and achievement, promoting desire to continue improvement. Clinical data will supplement the interviews to show a full picture of how the unit adapted to its situation. The transcribed interviews will then be distilled to highlight the critical, meaningful points in the plot line where learning and adaptation took place. This resulting manuscript is the tangible learning history. Internal dissemination will involve sharing the learning history with the organization and facilitating group discussions about the findings with members of the organization. Through this process, we anticipate the unit will be able to promote more effective interventions to improve patient care.

Cody Craig and Charles Yeager, Snow College Health Logically, a rise in income should lead to a healthier population. Diseases like malaria, cholera, and HIV/AIDS are associated with poverty, low rates of education, and poor infrastructure in many parts of the world. In populations with higher per capita income (or “wealth”), these diseases are not as common. However, while our higher socioeconomic classes have fewer poverty linked diseases, is the overall health of people across Utah as high as we might expect it to be? Diseases like obesity, heart disease, and diabetes (known as diseases of affluence) are becoming more and more common, even though advanced health technology and healthcare availability increase. This project will examine the relationship between income level, diseases of poverty, and diseases of affluence. Data will be aggregated from a number of sources and mapped using a geographic information system. A regression analysis will be conducted to determine if variables are positively or negatively correlated with diseases of poverty and affluence in Utah.

Whittni O’Brien, Dixie State University Health St. George residents are currently at risk from poor indoor air quality. The objective of this study was to provide citizens with simple solutions to purify their indoor air and avoid the side effects of pollution. The rising threats include benzene, formaldehyde and trichloroethylene. These carcinogens are directly linked to heart disease, birth defects, asthma and premature deaths in individuals. The study was conducted to see just what could be done to combat these hazards and provide the necessary information to resolve the levels of indoor air pollution to residents. A standardized questionnaire was issued to find out how educated locals were about the pollution levels and air quality within the community. Questions covered a variety of aspects including exactly what the threats were to specific methods of indoor air purification. To reduce the number of carcinogenic related health issues, participants were provided with a pamphlet including easy to follow steps to cleaner indoor air and outdoor air pollution. The objective result yielded plants to be the best solution. Aloe vera plants are not only grown locally, but are easy to propagate. These plants are known for their ability to remove formaldehyde from the air and therefore an inexpensive and readily available resource that will assist residents. Other solutions found included greenery such as moth orchids, snake plants and the ficus tree. All of these plants are easy to maintain with local climate conditions. By providing residents with the proper education and resources, the overall health of the population will rise. The conclusion of the study offers vital knowledge to the community and a progressive approach to cleaner indoor air for a healthier living space.

Erika Brown and Stacie Hunsaker, Brigham Young University Health Health care professionals are often challenged with starting an intravenous (IV) line in patients who are dehydrated, have suffered trauma, or are in shock. Nurses and physicians can become frustrated by the multiple attempts and patients can lose valuable time. An alternative route to deliver the needed fluids and medications to these critical patients can be achieved by accessing the blood supply inside the bone. Intraosseous (IO) access is a safe, rapid, and an effective alternative method to deliver medications and fluids to these critical patients (Hunsaker and Hillis, 2013). I was mentored in the practice of qualitative research and interview process in a study related to difficult IV access. A qualitative research study was performed at Hospital Luis Vernaza in Guayaquil, Ecuador, to determine the complications faced in providing timely care to critical patients, and to assess their knowledge and use of IO therapy. Interviews were performed, and, because of my fluency in the Spanish language, I was the primary interviewer. These interviews were analyzed to assess the need of interventional IO therapy. Through the interviews, preliminary results demonstrated a need for an organized IV algorithm in this large hospital. The difficult IV algorithm has been developed and will be presented to the health care professionals at Hospital Luis Vernaza in the spring of 2015 on a Brigham Young University College of Nursing Global Health stay in Guayaquil, Ecuador.

Delena Hanson, Dixie State University Health Debate in diagnostic imaging over the effectiveness of shielding the patient from the incident (primary) beam compared to shielding from the scattering beam once it has hit the image receptor is ongoing. Because radiation in any amount can cause long term effects, it is the ethical obligation of those in the profession to keep the dose of radiation to the patient as low as reasonably achievable. Backscatter is radiation that goes through the patient, contributes to the diagnostic image, then still has enough energy to hit the image receptor and scatter back toward the patient. While previous studies indicate that dose to the gonads from the primary beam during chest x-ray exams are low, this additional research assesses the amount of backscatter that happens during a chest x-ray to determine at what point patient size is a factor that increases patient dose. As more technique must be used for larger patients, increased interactions will occur and therefore present a higher probability of backscatter that can add to the patient’s gonadal dose. This research quantifies whether and at what point placing a lead shield between the patient and the image receptor will reduce dose to the patient by measuring the thickness of a patient receiving chest x-ray and using a pocket dosimeter to measure the amount of radiation scattering back from the patient to compare with data from the incident beam.

Paydon Newman and Joseph Rebman, Dixie State University Health Several studies (Shepley, 2012; Sherman-Bien, 2011; Walch, 2010) have found that sunlight has a stress-reducing effect on those who are exposed to it. An innovative new design of artificial lighting known as RaLight is proposed to reflect light with a color rendering index nearly identical to natural sunlight. This study will examine the relationship between exposure to RaLight (as a substitute for sunlight) and levels of stress. RaLight is predicted to decrease levels of stress in test subjects. In a commercial call center setting, test subjects will consist of an estimated 50 employees both male and female with ages ranging from 18 to 30 years. This research is designed as a single subject experiment (ABA). The initial control condition will be the common indoor environment which exposes patients to standard fluorescent lighting. Replacing light fixtures with RaLight will then establish both the second phase of the experiment and the independent variable. A follow up re-installment of the initial fluorescent lighting will be conducted post-RaLight phase. Throughout each phase, questionnaires regarding the overall well-being of employees will be completed.

Sam Katz, University of Utah Fine Arts “Tom Stockham: The Father of Digital Audio Recording” is a 30-minute documentary film about former University of Utah professor Thomas Greenway Stockham, Jr., who developed the first commercially viable method of recording sound digitally with extremely high fidelity and made it possible to edit sound and music using a hard drive. Despite the limitations of 60s and 70s computing technology, as well as a number of audio professionals who opposed to the shift to digital audio, Stockham believed in his ideas, persevered, and changed the way we listen to music forever. To this day, these innovations have dramatically altered the shape of the audio recording industry in music, television, and film. Despite Dr. Stockham’s many achievements, his story remains relatively unknown outside of the audio engineering world, even here at the University of Utah and in Salt Lake City, where much of his pioneering work was done. This film brings well-deserved attention to Dr. Stockham’s story. Sadly, Dr. Stockham passed away from early-onset Alzheimer’s in 2004, therefore I portray him by interviewing those who knew him best: his wife, his four children, and his colleagues. I situate Stockham’s life and work in a larger historical context by interviewing historians, musicians, and audio industry professionals, and by mining archival footage, family photos, voice memos, and magazines for relevant material. I travel from Seattle, to Boston, to Lake Powell, to Moab, to Salt Lake City. In homage to Stockham, I use the sound and music of the film, rather than images, as the locus from which meaning and emotional power are derived. The finished film serves as an important educational and historical resource and helps to preserve an important piece of the history of the University of Utah, Salt Lake City, and the State of Utah in general.

Kelly O’Neill, University of Utah Fine Arts After studying the formal qualities of photographic production and the canonic narratives of art history for over three years at the U, I am still left with a pressing question: how can this medium of artistic self-expression also be considered evidence admissible in the court of law powerful enough to elicit felony convictions? How can these mechanical images which I have been trained to see as subjective representations of artistic sentiment in their contrast, tonality, and composition simultaneously be objective records of fact in judicial and scientific discourses? If the medium of photography does exist how is this single operation able to function in such heterogeneous and contradictory discourses? Through my works and research I investigate these and other questions concerning the photographic medium’s ambiguous nature as a simultaneously aesthetic and empirical object. By combining a vast assortment of photographic forms from contemporary GIFs to historical processes such as the Cyanotype, my work reveals the multiplicity of the photographic form and its dubious ability to function within seemingly contradictory systems of knowledge production. Interrogating the processes by which photography has been used and abused, my project does not propose to reveal the truth of photography, but rather underlines the importance of seeing photography in a new and radicalized fashion. The images that I create contemplate the liminal spaces of photography in which its factual, emotional, institutional, and narrative truths commingle; fragmenting not only the solidity of the photograph but also the cultural and institutional systems it predominates. More than just a series of art works, my research seeks to bring a broader discourse on photographic meaning into a serious academic engagement which does not treat it as a simple device for conveying meaning but as a specific and complex subject in its own right.

Steven Saline, Dixie State University Fine Arts Electronic Dance Music or EDM has grown from its underground club origins in the late 70’s to early 80’s to become a widespread phenomenon in pop music. Through out those years, EDM has been categorized in previous terms such as Techno, and Electronica. Today EDM can be heard in music festivals through out the world and is now widely experienced in the US. Much of the genres within EDM such as Dubstep, Hardcore,Trance, etc… were created and have evolved outside the US, however; House and Techno originates here in the US. In this presentation I will discuss the history of some of the popular genres in EDM, present how each of the genres started whether they were created on their own or their evolution from previous electronic music, the history of its origins, how the music evolved in Europe, and its move to the US as we hear the music today. I will present how wide-spread EDM has become and how diverse the various forms are within the genre. I propose that if EDM continues in the direction that it is moving now, EDM will continue to grow among all other forms of music in the world for years to come.

Melissa Warren, Weber State University Physical Sciences Spot tests are commonly utilized as presumptive qualitative tests for detecting chemical substances. Such tests are the basis for detection of illegal drugs or for cleaning validations in manufacturing systems. In this study we evaluate the use of Scott’s reagent and Mandelin reagent for the detection of trace quantities of diphenhydramine (Benadryl). These reagents have been reported to give false positive tests for illegal drugs such as ketamine (cocaine) when diphenhydramine is present. Our studies were focused on enhancing the detection limits of these reagents and their application of swab tests for diphenhydramine. We report the limits of detection and swab techniques that enhance selectivity and sensitivity for this analyte.
