2014 Abstracts

Natalie Jarvis, Brigham Young University Fine Arts My fascination with the process of distortion and my desire to bond with the transformative nature of the ceramic medium drives my exploration of its abilities and limitations. Making myself a part of the natural movement of the clay and helping each piece to find its abstracted balance is important during the creation process.

Rebekah Jackson, Brigham Young University Fine Arts This project has been an involved approach to studying the history of costume design, both through conventional research and the more tactile construction process. While Edith Head is a renowned costume designer with many books and articles on her life work, less has been done to understand how her designs functioned and evolved from concept to completion. But this process is essential to understanding her career’s success, as it opens valuable insights to how Head thought as a designer. It reveals what she was and wasn’t willing to compromise on, how she balanced aesthetics with practical considerations and how she worked with an actor or actress to achieve the proper look for their character. In Blake Edward’s production The Great Race, Edith Head’s designs showed this transformation of idea to reality by compromises between the original designs and finished garment. A simple red suit, worn in this production, exemplifies such compromise and was the construction portion of my research. Recreating this costume, in conjunction with conventional research on Head and her work, revealed important decisions Head made from materials to fit, how and why she changed her original design and the general approach she used in her work. These insights combine to form the basic pattern used in her creative process, applicable to both costume design and related fields as it unveils the thought process of one of Hollywood’s most successful career women.

Yonic Michaca, Utah Valley University Physical Sciences It is well known that some of the worst air pollution in the country each winter is found along the Wasatch front in northern Utah. This study examines the effects of environmental pollutants on the production of the novel compounds produced by the endophytes found in Rumex crispus. The Rumex crispus plant was selected due to its natural medicinal uses. It is anticipated that environmental pollutants have an effect on the production of bioactive compounds in order to protect their plant host from foreign pathogens. The theory is that the more stressful environment a plant lives in, i.e. desert climates, high altitude, and man-induced stresses such as pollution, the more bioactive compounds the endophytes produce as a response to protect their plant host. This study analyzes the effects of environmental pollutants along the Wasatch front on the production of novel bioactive compounds produced by the endophytes found in Rumex crispus. Plant samples are also collected from sites near the Wasatch front, but they are not exposed to the same amount of air pollution to be used as a control.

Ting Ruan, University of Utah Physical Sciences Cardiovascular complications are more prevalent in patients with diet-induced obesity and type 2 diabetes. Both of these conditions are associated with elevated levels of free fatty acids (FFAs). Elevated FFAs might precipitate cardiovascular complications by disrupting endothelial nitric oxide (NO) synthase (eNOS) enzyme function. The physiologically abundant saturated FFA palmitate decreases eNOS phosphorylation at serine 1177 (p-eNOS S1177) in a ceramide and protein-phosphatase 2A (PP2A) -dependent manner. p-eNOS S1177 is a positive regulatory site on the eNOS enzyme. As such, p-eNOS S1177 to total eNOS can be used as an estimate of eNOS enzyme function. We sought to determine the extent to which two other phosphatases that are abundant in the cytosol i.e., protein phosphatase 1 (PP1) and protein phosphatase 2B (PP2B) might contribute to palmitate-induced reductions in p-eNOS S1177 to total eNOS. Bovine aortic endothelial cells (BAECs) were treated for 3 hours with 500 uM palmitate or vehicle in the absence and presence of the PP1 inhibitor tautomycin (3 uM). p-eNOS S1177 to total eNOS was assessed using immunoblotting procedures. Palmitate-induced reductions (30±3%, p<0.05, n=3) in p-eNOS to total eNOS were similar in the absence and presence of tautomycin. These data indicate that PP1 does not contribute to palmitate-induced disruption of eNOS enzyme function. Next, BAECs were treated for 3 hours with 500 uM palmitate or vehicle in the absence and presence of the PP2B inhibitor cyclosporine (100nM). Palmitate-induced reductions (31±4%, p<0.05, n=3) in p-eNOS to total eNOS were similar in the absence and presence of cyclosporine. Taken together, these data suggest that neither PP1 nor PP2B contribute to palmitate-induced reductions in p-eNOS S1177 to total eNOS.

Frederickk Sudbury, University of Utah Physical Sciences Triphenylphosphine stabilized gold nanoparticles were synthesized using a method developed previously by the Jennifer Shumaker-Parry group. Aminated silica colloids were obtained from the Ilya Zharov group. The gold nanoparticles were adhered to the silica colloids using a method developed for another purpose by the Zharov group. The presence of the particles on the silica colloids was confirmed using both scanning and transmission electron microscopy. The catalytic activity of the gold nanoparticles both with and without adhesion was investigated. It was found that free nanoparticles had significant catalytic activity, in agreement with previous research. Gold nanoparticles attached to silica colloids do not seem to exhibit the same level of catalytic activity as the free particles. It was also found that not all the gold nanoparticles adhered to the surface of the silica particles. Experiments were conducted to determine if there was a critical concentration of silica colloids that would allow for high levels of adhesion of the gold nanoparticles. It was found that only by adding a significant excess of silica colloids to the solution can all the gold nanoparticles be removed from the solution. It was also found that the silica can be saturated with gold nanoparticles by including a small amount of them in a very concentrated gold nanoparticle solution. Further studies for functionalization of the silica colloids and the ability to physically isolate the silica with gold nanoparticles from free nanoparticles are currently in progress.

Kip Brower, Utah Valley University Physical Sciences Juniperus osteoperma has been reported to exhibit beneficial pharmacological activity against symptoms of diabetes, as a traditional treatment for kidney ailment and the essential oil of juniper berries has also been subject to investigation for antioxidant activities. Endophytes, particularly endophytic fungi, have produced numerous novel bioactive compounds, several of which are currently used as antifungal, anti-bacterial, and anti-cancer agents in organisms other than their plant hosts. This investigation looks into the possibility of endophytic fungi being a means of producing compounds that may be a functioning agent in antioxidant, antifungal, or hyper/hypoglycemic activities of Juniperus osteoperma. The investigation involves samples of Juniperus osteoperma collected from multiple different locations within Utah, and isolates the resident endophytic fungi.

Stephen Erickson, Brigham Young University Physical Sciences “The spherical protein ferritin has often been used to fabricate nanoparticles of various shapes and compositions with its walls. Ferritin occurs naturally with a ferrihydrite (FeOOH) mineral core, but it has also been used to synthesize nanoparticles of several other semiconductors. While the methods for creating these nanoparticles within ferritin are well established, the characterization of such nanoparticles is not. Previous studies on native ferrihydrite core ferritin disagree on the band gap, giving values anywhere from 1.1-3.5 eV, depending on the method. We have used absorption spectroscopy to measure these band gaps with an unprecedented accuracy of up to .01 eV. This method also allowed us to determine that ferrihydrite nanoparticles are indirect gap semiconductors. By employing this method on particles of various sizes, we have shown the effects of quantum confinement, resulting in variations in the band gap. We also provided the first ever direct evidence that ferritin works to crystalize its core with time, an effect that has long been theorized but never observed. By characterizing the effect of size and time on nanoparticle band gap, we have shown the potential for selectively tuning that gap. This opens up a world of possible applications in light harvesting and photo detectors. By controlling the band gap, we will be able to select which wavelengths of light are absorbed, allowing for full spectrum photovoltaic cells and wavelength specific optical detectors. Future studies will focus on nanoparticles of other metal hydroxides and various anion replacements to further expand our tunable range of band gaps.

Byron Millet, Weber State University Physical Sciences The relative solvolysis rates of norbornenyl derivatives have been of interest. To date, only one other norbornenyl compound has been found that solvolyzes slower than anti-7-norbornene. It has been suggested that through-space interactions between π-bonds plays a significant role in stabilizing the carbocations. However, through-space interactions do not account for the similar observed solvolysis rates of nearly identical compounds both with and without adjacent π-bonds. Studies have shown that the stability of these compounds is significantly affected by σ-bond interactions. We report on our current computational study of the relative energies of several norbornenyl compounds with and without adjacent π-bonds to evaluate both π-bond and σ-bond effects on the stability of the norbornenyl cations. The effect of a ketone functional group on the relative stability of the carbocation is also analyzed. The literature solvolysis rates of the various norbornenyl derivatives and the stability of their respective cations is compared. With some exceptions, a correlation was found between the stability of a derivative’s carbocation and its respective rate of solvolysis.

Jeremiah Rundall, Utah Valley University Physical Sciences Utah Valley University has a long-term program of groundwater development in the Trans-Mexican Volcanic Belt in the state of Guanajuato, Mexico, in cooperation with Choice Humanitarian. Thus far, we have drilled a successful 50-m well in basalt and an unsuccessful 22-m well in rhyolite. Well sites have been chosen based on spring locations and fracture traces (linear features as seen on aerial photos). The objective of this study is to measure and model the geoelectric and magnetic characteristics of fracture traces as a means of determining which fracture traces are most indicative of actual fractured rock. Thus far, studies have been carried out on 20 fracture traces in rhyolite in the Trans-Mexican Volcanic Belt, six fracture traces in rhyolite/diorite/monzonite of the La Sal Intrusives in the La Sal Mountains of Utah, and one fracture trace in rhyolite of the Soldiers Pass Formation west of Utah Lake. The total magnetic field has been measured at about 1-m spacing along profiles perpendicular to fracture traces using the Geometrics G-856 Proton Precession Magnetometer. Geoelectric soundings for resistivity, chargeability and self-potential have been carried out both on and off fracture traces using the Iris Instruments Syscal Junior Resistivity Meter with the Schlumberger array parallel to the fracture trace at spacings in the range AB/2 = 2.29-137 m. Geoelectric profiles have been carried out perpendicular to fracture traces (array parallel to the fracture trace) at spacings AB/2 = 15.2 m and 137 m. Geoelectric and magnetic modeling is being carried out using the 1X2D-GM Magnetic Interpretation Software and the 1X1D Sounding Inversion Software. Preliminary results indicate that some fracture traces are associated with both magnetic and electrical resistivity lows consistent with intermediate depth (~ 50 m) fractured rock, although not all fracture traces have these characteristics. Further results will be reported at the meeting.

Alexandra Kent, University of Utah Physical Sciences Prescription drug overdose and abuse is a leading cause of death in the United States. It is a serious issue and has become increasingly problematic as opioids are being prescribed at a higher frequency. For this reason, fast, accurate detection of small drug molecules is crucial. The current standard for use in clinical drug detection is an enzyme-linked immunosorbent assay (ELISA) that uses a series of antibodies to bind to the target drug and enable quantification via a colorimetric output. However, the antibodies used in an ELISA often cannot distinguish between similar molecules. Aptamers are short sequences of DNA that have emerged as a promising alternative to antibodies, as they are generated in vitro, where negative selections can be used to increase target selectivity. These aptamers can be cleaved to make split aptamers that only assemble in the presence of the target small molecule. One inherent problem of this system is the need for split aptamers that are selective for their small molecule targets. While there are many known aptamers, there are only a few known split aptamers that bind small molecules. Separating aptamers with a privileged, three-way-junction structure provides a reliable method to generate new split aptamers.

Jazmin Myres, Brigham Young University Physical Sciences In scan-based array measurements, stationary reference sensors are needed to temporally correlate the different measurement scans and produce coherent complex pressure fields. Because the number of references required increases with the number of subsources contributing to the sound field, an extended, partially correlated source comprising many ill-defined sources can result in significantly increased measurement complexity. A different approach to creating spatiotemporally coherent pressures is demonstrated here. Scan based measurements of a partially coherent line source have been taken in an anechoic chamber. This experimental data has been used to explore “stitching” together a complex pressure field by spatially overlapping measurement scans instead of using separate reference channels. Various methods of stitching have been explored and the most robust method identified. Unwrapping of intrascan phases is first accomplished with a two-dimensional phase unwrapping algorithm. Individual scan positions are then stitched together using median phase differences between multiple adjacent scans to create coherent planes of data. Amplitude-stitching is done by averaging across scans and preserving the integrated squared pressure across the overall aperture. This method has been verified using reference microphones. This stitching method has been applied to scan based measurements of a military aircraft, exhibiting its effectiveness dealing with a partially correlated complicated source. This method works well for low-frequency jet data, where there is not a ground-based interference null creating a physical phase discontinuity. This technique provides direction for efficient experimental design for scan-based array measurements of extended sources. [Work sponsored by ONR.]

Brandon B Davis, Utah Valley University Physical Sciences A recent study (Ferreira 2013) examined concentrations of fluvial As and transition metals associated with As in Provo and American Fork Rivers, which flow westward across the Wasatch Range and drain into Utah Lake. Within Utah Valley average fluvial As for Provo River (As= 0.342 mg/L) and American Fork River (As= 0.152 mg/L) exceeded the EPA standards for freshwater streams for acute exposure (As= 0.340 mg/L) and chronic exposure (As = 0.150 mg/L), respectively. The objective of this study is to determine whether elevated levels of As and other heavy metals also occur in shallow groundwater in Utah Valley. The objective is being addressed by analyzing water samples from the “backyard wells” in Utah Valley, shallow (depths < 10 m), hand-dug wells which many residents maintain as their "emergency water supply" or for small scale agriculture. Since nearly all backyard wells are unregistered, they are being sought through conversations with water departments, real estate listings and local residents. Water and sediment samples are also being collected from American Fork River, Hobble Creek, Provo River and Spanish Fork River, which drain into Utah Lake. Samples are being analyzed for nitrate, phosphate and sulfate using the Hach DR-2700 Spectrophotometer, while the PerkinElmer Optima 8000 ICP-OES is being used to measure for As, the transition elements Co, Cu, Cr, Fe, Mn, Ni and Zn, and other associated elements Ag, Cd, Pb and Ti. Preliminary results indicate that shallow groundwater As in the American Fork watershed is much lower (mean As= 0.0022 mg/L) than fluvial As and an excellent negative correlation (R2 = 0.83) between groundwater As and Ti. It is suggested that TiO2, which may originate in the Cottonwood Stock in the American Fork watershed, may play a role in the demobilization of groundwater As. Further results will be reported at the meeting.

Tyler Jones, Brigham Young University Physical Science This project takes advantage of an inexpensive integrated circuit to create a wavelength meter. The circuit has an array of photodiodes, each of which has an optical filter of a different color. The filters cause each diode to respond differently to different wavelengths of light. The relative amplitudes of the signals are then used to compute a wavelength based on known responses for various wavelengths recorded in a calibration stage. The project focuses on improving precision of the hardware and developing an algorithm to do the computation.

Stephen Ruegg, University of Utah Physical Sciences The Black Peaks Formation (BPF) from the Tornillo Group in Big Bend National Park (BBNP) is comprised of a series of stacked paleosols and sandstone channels deposited by a fluvial system in a sub-tropical intramountain basin during the Laramide orogeny. Paleosols constituting the BPF display alternating drainage and development conditions. The BPF is bounded by the Late Cretaceous Javelina Formation and the Early Eocene Canoe Formation and is therefore thought to be of Paleocene age (65.5-55.8 million years ago). The BPF is an interesting target for paleoenvironmental reconstruction because little data have been generated from the Paleocene for sub-tropical regions, limiting the validation of global climate model predictions in these regions. However, previous attempts to resolve the age of the formation using biostratigraphy, magnetostratigraphy and chemostratigraphy gave ambiguous results limiting the potential of the BPF for paleoenvironmental reconstruction. We analyzed the carbon isotope ratio (δ13C ) of carbonate nodules collected from pedologically distinct paleosols throughout the BPF. δ13C of carbonates nodules found in reduced black paleosols are systematically 3-4‰ lower than δ13C from non-black paleosols from neighboring stratigraphic intervals. We hypothesize that this isotopic difference is related to the lower contribution of atmospheric CO2 to soil CO2 in water-logged and/or poorly drained black soils. Large-scale stratigraphic patterns of carbon isotope variations in carbonate nodules from non-black paleosols throughout the BPF strongly resemble well-documented secular changes in δ13C values of marine carbonates for the Paleocene. Several recognizable features are present in both curves, including the Paleocene Carbon Isotope Maximum (PCMI) and possibly the Late Danian carbon isotope excursion (LDE). These features provide a new basis for correlation of the BPF to the global geological timescale, and suggest that the Formation preserves a 6 million year record of deposition and paleoenvironmental conditions spanning the majority of Paleocene time (63-57 million years ago).

Christopher Mansfield, Westminster College Physical Science The method currently used to measure monomethylmercury (MMHg) in natural waters involves a lengthy distillation step in order to remove certain ions and dissolved organic matter that have been reported to interfere with the subsequent reaction in which MMHg is ethylated. It has recently been reported that the analysis of MMHg in seawater by direct ethylation was successfully carried out, thus removing the day-long distillation. However, the effect of many potential interfering ions and compounds on this method have not been characterized, and it has not been tested for use in natural freshwaters or the hypersaline waters of the Great Salt Lake. Thus, these became the two goals of this project. We found that optimal ethylation conditions included buffering samples to pH 4.0-4.1, reducing the amount of sodium tetraethylborate, adding EDTA to complex interfering trace metals, and adding chloride to overcome interferences by thiols and organic matter. We have since employed this improved method to analyze MMHg in natural water samples from fresh and saline lakes, achieving > 90% MMHg spike recoveries without the use of distillation.

Jasmine K Bishop, University of Utah Physical Sciences In my presentation, I will discuss the method of creating insulating gaskets for high pressure experiments using diamond anvil cells. In standard diamond anvil cell pressure experiments, metal gaskets are typically employed. However, in order to study the electric and magnetic properties of a sample without worrying about interference of the metal gasket itself, insulating gaskets are used. The insulating material needs to be ductile and yet hard enough to maintain a certain level of structure. Epoxy is ideal for ductility but is not hard enough to maintain a diamond indent under pressures generated by diamond anvil cells. When mixed with a diamond powder however, the mixture is both ductile and structurally sound. In this study we have modified the previous methods of insulating gasket preparation by addition of a metal sheet to increase the strength and ductility of the gasket. The part of the gasket that is metal can be used as an electrical lead to measure sample’s conductivity. In this design the mixture of diamond and epoxy is applied to a thin 100 micrometer metal sheet and a focused beam of high power IR laser is used to drill a hole in the gasket . I will describe the design of the optical path and the details of the gasket preparation and will present some of the gaskets that I have made.

Stephanie Bartlett, Utah Valley University Physical Sciences Ephemeroptera, commonly referred to as mayflies, are found throughout the world. Within the order of Ephemeroptera resides a superfamily, Ephemeridea, commonly called burrowing mayflies. This common name was acquired due to certain physical and behavior characteristics present as nymphs. Ephemeridea nymphs live in the silt of aquatic environments and have adaptations for burrowing which include strong legs, as well as mandibular tusks. One exception to this is the family Behningiidae, which burrow, but lack the commonly associated mandibular tusks. Morphological data supported Behningiidae as sister to the other tusked burrowing mayflies, indicating that first burrowing behavior evolved and was later followed by the development of tusks(McCafferty; 1975 and 2004). While morphological data provides important insights into the evolution and phylogeny of mayflies, the development of molecular phylogenetics offers new contributions when determining evolutionary relationships within this superfamily. Objective: The purpose of this study is to investigate the relationships of the families of burrowing mayflies in order to test the hypothesis of tusk evolution. Methods: The specimens were acquired from collection efforts and colleagues. For each specimen the following laboratory procedures were carried out: DNA extraction, gene amplification via polymerase chain reaction, visualization via gel electrophoresis, and DNA sequencing. The genes targeted for sequencing included 12S mitochondrial rDNA, 16S mitochondrial rDNA, 18S nuclear rDNA, 28S nuclear rDNA, H3 nuclear protein coding, and CO1 mitochondrial protein coding. Data was also acquired from Genbank in order to augment missing data. Taxon sampling consisted of around 20 ingroup and 5outgroup taxa. Phylogenetic relationships were estimated using Maximum Parsimony, Maximum Likelihood, and Baysian methods. Conclusion: The families Behningiidae, Potamanthidae, Palingeniidae were supported as monophyletic. Behningiidae nested well within the other burrowing families. Hence, tusks evolved and were subsequently lost in the family Behningiidae even though it retained the burrowing lifestyle in the nymph.

Mattie Jones, Dixie State University Physical Sciences 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. Current methods of isolating components of samples by their unique chemical properties are lengthy and often destroy important forensic evidence. Ionic liquids possess the necessary chemical properties to ensure efficient extractions, while maintaining the forensic signatures of the original materials. They also provide a one-pot approach that avoids intermediate species and increases analyte yield while extracting and separating constituents in a more efficient manner. By combining traceable dyes with an ionic liquid, the versatility of single-component extraction-separation-identification was demonstrated. Analysis using absorption and fluorescence spectroscopy validated complete extraction and recovery of trace analytes. Following extraction and isolation, identification by infrared 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.

Phillip Lundgreen, Utah State University Physical Sciences By developing a low-noise, high-voltage battery power supply, system noise has been reduced, increasing accuracy of conductivity measurements of highly disordered insulating materials. The method involves a simple parallel plate capacitor setup with the sample sandwiched between electrodes, a voltage potential applied to one electrode, and a measurement device applied to the back electrode measuring current. Previous methods involved use of a commercial power supply with a claimed low noise and high linearity, but with a low AC output ripple. At high voltages (1000 V), however, the noise became apparent in the readings and an unacceptable uncertainty was introduced in our precision conductivity measurements. Through the use of a stable dc battery high-voltage power supply, we were able to reduce noise in current measurements and achieve a more accurate measurement of conductivity for various samples.

Zachary Anderson, Brigham Young University Physical Sciences Correlation analysis is useful in extracting spatiotemporal relationships between signals and can be used to examine features of near-field jet noise for source properties. Characteristic correlation envelopes determined by Harker et al. [JASA 133, EL458 (2013)] can be used to relate correlation lengths to fine and large-scale turbulent structures. As an extension, cross-correlation shows spatial variation in jet noise and further reveals the transition between short (fine-scale) and long (large-scale) correlation lengths. These analyses are applied to a military jet dataset of a ground based linear microphone array positioned 11.6 m from the jet axis. Correlation analyses over multiple engine conditions and observation directions are reported. In particular, a maximum correlation coefficient greater than 0.5 exists over a range spanning multiple wavelengths in the region of greatest overall sound pressure level at military power.

Ian Sohl, University of Utah Physical Sciences Current software in the High Altitude Water Cherenkov (HAWC) Telescope data collection system only triggers saving of events that pass a specified number of hits and energy. Our analysis of the untriggered (and unsaved) data will identify the number of potentially significant events that are bypassed by the existing software. By the application of a sorting function onto current Monte Carlo generated data, we can categorize incoming events into various types of particles, primarily muons, while also filtering out randomized noise from the photomultiplier tubes used in HAWC. Due to the relatively low rate and energy of the photomultiplier tube noise, many of the significant events for the untriggered set are potential useful particles. Our triggering algorithm, based on the energy, timing and saturation of the tanks is primarily focused on separating muons from the bulk of data. These raw rate data for small events are a relatively unexplored area for HAWC and measurements can be useful for a variety of calibration tasks for the telescope. They can be useful for understanding the impact of the atmosphere on the telescope’s data collection, as well as the triggering of the photomultiplier tubes through secondary sources. This untriggered data can also be used in a variety of useful forms not directly related to HAWC’s primary usage goals, primarily solar physics. Due to the relatively low energy and hit count from solar events, most of the data are thrown away by the triggering algorithm.

Mallory Millington, University of Utah Physical Sciences Groundwater in the western United States is a limited and important resource for agriculture, industry, and residents alike. Knowing the movement of groundwater is critical to understanding the potential of groundwater contamination from human activities. While groundwater flow is difficult to quantify, it typically recharges in high elevation and discharges towards lower elevation. The first commercially-approved tar sands mine in eastern Utah is located on a ridgetop in the PR Spring area within the high plateaus on the south rim of the Uinta Basin. To evaluate the potential of groundwater contamination due to tar sands mining a study was conducted to understand groundwater flow in the PR Spring area, specifically the canyon directly south of the tar sands mine called Main Canyon. Water samples were taken from four groundwater springs at elevations ranging from 7040 to 8040 ft in or near Main Canyon. Water quality measurements taken in the field showed that the lower springs exhibited higher conductivity (900 vs. 636 μS/cm) and lower dissolved oxygen (30% vs. 88% saturation) than the higher elevation springs. This suggests that the lower springs have had a greater amount of water-rock interaction and so are chemically more evolved than the springs at higher elevations. SF6 age dating indicated that the high elevation springs are younger than the lower elevation springs, 5.5 vs. 16.0 years since recharge respectively. The field parameters and SF6 age data all indicate that higher elevation springs are younger and less chemically evolved than the water at lower elevations. This indicates that the springs in Main Canyon are sourced from local recharge at the ridgetops. Given these findings the tar sands mine should consider taking preventative measures to protect groundwater resources.

Laurin Wilson, Utah State University Social and Behavioral Sciences Premature birth and subsequent hospitalization of an infant in the Newborn (or Neonatal) Intensive Care Unit (NICU) can be an extremely stressful time for parents and has been associated with maternal depression, anxiety, and decreased coping ability (Hack, Taylor, Klein, & Mercuri-Minich, 2000; Hughes, McCollum, & Sheftel, 1994; Partridge et al., 2005; Shaw, Sweester, St. John, Lilo, Corcoran, Jo, & Horwitz, 2013). Interventions to reduce parents’ stress levels during the hospitalization of their very preterm infants have mixed results (Boyce, et al., 2008; Matricardi, S., Agostino, R., Fedeli, C., & Montirosso, R., 2013). This study examined the medical, family, and maternal mental health factors that influenced feelings of parental distress for mother of very premature infants.

Dusty Pilkington, Weber State University Social and Behavioral Sciences Boundaries dividing political authority rarely match natural water flow. Multiple agencies, often with competing policies and agendas, manage water within single watersheds. This discrepancy can render management efforts ineffective. Local water agencies include soil conservation districts, local health departments, and engineering agencies. Agencies have varying funding sources, managerial structures, and jurisdictional boundaries. Fragmentation can frustrate management efforts at watershed scales. Comparisons between natural watersheds and human political geography can therefore be helpful in avoiding conflicts. This research examines discrepancies between political and physical geographies for sections of three Utah rivers : the Logan and Provo Rivers, and Red Butte Creek. These rivers are being targeted for intensive research as part of a statewide, multidisciplinary water sustainability project, titled iUTAH. Water-related land use (WRLU) data acquired from Utah’s Automated Geographic Resource Center were analyzed using ArcGIS geoproceessing tools. WRLU contributing to water quality in urban river reaches is described. WRLU was examined using three boundary sets, comparing the political geography of the river reaches, as depicted in municipal boundaries and management areas of community water providers, to their physical geography, as depicted in United States Geologic Survey Hydrologic Unit Code (HUC) watersheds. WRLU mixes using political infrastructure were contrasted with land use mixes from HUC boundaries. WRLU was classified in seven categories: residential, commercial/industrial, riparian/water features, irrigated agriculture, non-irrigated agriculture, farmsteads, and parks/open spaces. A gradient from rural Heber, to urbanizing Logan, to fully urbanized Red Butte Creek is shown. While Red Butte Creek HUC boundaries showed 53.8 % residential land use, Red Butte Creek municipal boundaries and community providers totaled 26 % and 39 % residential use, respectively. Differences emerged when irrigated agriculture was assessed using HUC boundaries. Irrigated agriculture totaled 0.2 % in Red Butte Creek, with Logan showing 29. 7% and Heber irrigated agriculture sitting at 41.1 %.

Luz Maria Carreno, Utah State University Social and Behavioral Sciences Significance: Patients’ health literacy, or ability to comprehend and understand health information, influences their health status, knowledge about medical care and conditions, and hospitalization and adherence rate (Andrus, & Roth, 2002). Low-English proficiency patients are especially at risk, given they must overcome English and health literacy barriers.

Kelsea Hill, Utah Valley University Social and Behavioral Sciences Sexuality has long been identified as foundational in the lives of married couples. An area lacking in research, however, is the transition into sexuality made by couples who practiced abstinence prior to being married. The data for this study comes from a survey of 597 respondents that had practiced abstinence before being married. This focuses on the qualitative responses to questions asked abstinent couples about what helped make the transition into sexual intimacy, what purpose(s) sex has in their relationship, what they wished they had discussed prior to having sex, and what challenges they experienced in the transition into sexual intimacy.

Jared Glenn, Utah State University Social and Behavioral Sciences Previous research shows that girls and women tend to prefer and perform better in classes taught by women. However, much less research analyzes the impact of instructor gender on learning outcomes among boys and men. This research fills that gap by analyzing the effect of professor gender on male college students’ achievement. Relying on survey and in-depth interviews among undergraduate men at a large research university, this study finds no significant empirical data that professor gender significantly impacts men’s academic achievement, in contrast to previous findings among girls and women. Interview findings, however, suggest that men prefer the tough grading, which they indicate is integral in male-taught classes. The study contributes to our understanding of gender differences in an academic setting and how that factor shapes learning outcomes and achievement.

Cassandra Southam, Utah Valley University Social and Behavioral Sciences Recruitment and retention are two of the most salient issues in emergency medical services (EMS) today. The National Association of State and regional EMS leaders, has twice identified recruitment and retention as the most important issues facing rural EMS agencies across the nation. The purpose of this study was to predict how Utah EMS personnel reached a point of wanting to resign using a stress model; value of job, self and other harm, spouse satisfaction, formal support as independent predictor variables. This data was obtained from an IRB approved statewide survey of all EMS personnel during the Spring of 2010. Of the 7,000 current EMS employees, 668 completed the survey, resulting in a 9.5 percent response rate. Results. The linear regression model indicated that the model explained 28 percent of the overall variance. A brief explanation of the findings indicates that all the direct paths were significant at the .05 level. The more they harmed themselves and others, the more they wanted to resign (Beta coefficient of .31). The higher their levels of Past Call-related Stress, the more they wanted to resign (.21). The higher their levels of spouse satisfaction, the more they wanted to resign (.07). The more they found value in their job, the less they wanted to resign ( -.18), And finally, the more they valued formal support from the debriefing team, the less they wanted to resign (-.10). Administrators and agency leaders can use these indicators to intervene when an EMS employee reaches a difficult point from the stresses and hardships of the job. Education, training, and available support can be very useful in preventing trained, experienced, and valued EMS employees from leaving the field. Local EMS directors and policymakers may find the results and study methodology useful toward designing and evaluating programs.

Desirae Wood, Weber State University Social and Behavioral Sciences Previous research has suggested that genetic polymorphisms may be correlated with specific behaviors and personality traits. The SLC6A4 gene that codes for the serotonin transporter contains a polymorphism in the promoter region that has been associated with anxiety, depression, and other psychiatric disorders. There have been reports linking SLC6A4 polymorphisms to traits such as neuroticism and harm avoidance (HA), but the relationship to novelty seeking (NS) is unclear. HA and NS are personality traits that have been correlated to some forms of risk taking, including casual sex. This present study was designed to explore a potential link between SLC6A4 polymorphisms in relation to novelty seeking, the frequency of casual sex behavior, and the cognitive assessment of how risky such behavior is. Undergraduate students (n=288) completed the Cloninger Temperament and Character Inventory, the Physical Risk Frequency Inventory, and the Physical Risk Assessment Inventory, and provided cheek swab cell samples for genotyping via polymerase chain reaction (PCR) and electrophoresis gel. Ongoing data collection and data analysis will be complete by the end of November.

Clinton Hardy, University of Utah Social and Behavioral Sciences Coercive treatment practices, while controversial, are commonly employed (by mental health professionals and parents) when admitting adolescents into outdoor behavioral healthcare (OBH; e.g., outdoor/wilderness therapy) and residential-based treatment settings. While coercive practices have been investigated in various adult treatment contexts, to my knowledge no study has examined coercive practices or pressures among adolescent treatments. As the first of its kind, my report investigates the relationship between adolescent-perceived coercive treatment pressures (i.e., negative pressures) and their affective reactions reported when entering OBH treatment. Negative pressures, or the perceptions of “threat” and “force” during admissions, are measured via the Negative Pressures Subscale (NPS) of the MacArthur Admission Experience Survey (AES). Affective reactions to entering treatment are measured via the Positive and Negative Affect Schedule – Expanded Form (PANAS-X). Although this study is still taking place, my interim analysis (N = 36, age range: 14-17) has so far demonstrated the following predicted relationships between negative pressures and affective reactions in OBH treatment admissions: An adolescent’s increased perception of negative pressures significantly correlates with (a) increased affective distress (r = .377, p = .037), (b) decreased affective positivity (r = -.61, p < .001), and (c) increased affective hostility (r = .464, p = .003). Therefore, significant medium to large correlational effect sizes are reasoned to be imminent. In recognizing that negative pressures might not only relate to an aversive admissions experience, but also negatively impact or delay positive treatment outcomes, future research is concluded to be essential.

Conor Fishback, Brigham Young University Social and Behavioral Sciences The Hashemite Kingdom of Jordan in recent years has seen the majority of its neighbors fall into some kind of violent conflict. Throughout the Arab Spring and the years following, the Jordan state has been one of stability and peace. One possible reason for the stability of the country could be its level of religious tolerance. One way to look at religious tolerance is to look at the geographic landscape of where the religious buildings are located within the cities of that country. This study analyzed the specific location of Christian churches in relation to Muslim Mosques in five different cities with a significant Christian population. Specific points representing the different faiths were gathered using GPS and then analyzed using GIS software. The geographic situation was analyzed for each structure. Geographic situation in this case referred to Christian churches and their proximity to Muslim Mosques, as well as the number of Muslim mosques and how adjacent they are in relation to the Christian churches. Photographs were taken of every location to determine the level of overshadowing or dominance that was taking place in that specific site. Using GIS, the Christian quarters in each city was analyzed. The majority of the cities, including the Jordanian capital of Amman, showed little or no clustering of mosques in relation to churches as well as little evidence of building dominance by either sect. Only one out of the five cities studied showed serious clustering of mosques around the Christian areas. While this study only analyzed a small part of what makes up a country’s level of religious tolerance, it can be expanded to other countries as well – not only Muslim states that are tolerant to Christianity, but also Christian or Western states and their tolerance to Islam.

Sai Samineni, University of Utah Social and Behavioral Sciences Introduction: Salt Lake Peer Court (SLPC) is an alternative program to juvenile justice where Salt Lake School District (SLSD) youth are referred for minor offenses such as truancy, disorderly conduct, fighting, theft, etc… The court is mediated by a panel of high school mentors who act as a jury which questions and mentors the referred youth while adult advisers facilitate court. Restorative justice-based contract requirements are used with many options including community service, attendance tracking, tutoring, counseling, and life skills classes. One major area that remains unaddressed among Peer Court’s disposition options is that of career exploration and college preparation. The intent of this research project is to create a new sustainable option that impedes the cycle of juvenile delinquency in families and increases their ability to stay free of crime by providing youth with tools to gain socioeconomic power through self-direction, goal-setting skills, and discovering their passions.

Chelsey Kenney, Utah Valley University Social and Behavioral Sciences The purpose of this study was to compare the stressors and supportive resources found between Utah emergency medical service personnel who divorced after certification to those who did not divorce.

Joshua Smith, Utah Valley University Social and Behavioral Sciences The current veteran populations that comprise Level 1 (18-24 years old) and Level 2 (25-34 years old) have had higher unemployment rates than their counterparts in the civilian population. One reason for this discrepancy is that veterans have put their lives on hold to make a commitment of public service by serving in the military. When they return home, many struggle to adjust from life in the military to civilian life. One issue includes finding employment in their areas of expertise without having a degree from a higher education institution. Many employers that are seeking veterans for their military experience prefer them to have a college degree in addition to their specialized training. Veterans are encouraged once they leave service to find a college major that best matches the skills and experience they gain while serving in the military. However, many veterans do not understand the full education benefits they receive from the government, what college majors best match their skillset, and what kind of benefits they can get from earning a college degree. Veterans have a lot to offer to both the college environment and workforce with their advanced technical and personal skills. This research paper will help determine if veterans do understand their educational benefits, if they have or will use their educational benefits, if they know what degrees could apply to their military training, and what the Veterans Administration and higher education institutions can do to better serve veterans to succeed for a life after the military with a college degree.

Maximilian Stiefel, University of Utah Social and Behavioral Sciences This paper examines the impacts of sugarcane cultivation on rural community resilience in municipios throughout Brazil. Whether sugarcane cultivation has generated vulnerabilities, such as population diffusion, ecological transformation, and adverse path dependencies, for rural community resilience is the primary focus. Resilience is critical in that it demonstrates adaptation efficacy for a community facing shifting capabilities. Social cohesion and capital also tie into how resilience correlates to meaningful interactions among individuals. Over the past thirty years Brazil became second to the U.S. in terms of global ethanol production, generating robust economic growth. However, sugarcane cultivation expansion has forced some cattle ranchers from southern Brazil to migrate north, resulting in the clearing of Amazon forestland for grazing. Pastureland displacement from sugarcane cultivation generates various concerns for rural economies, social cohesion, and socioeconomic class disparities. There currently lacks abundant examination of impacts to rural communities adjacent to sugarcane ethanol cultivation and production. I formulate a regression analysis to gauge shifts in resilience from sugarcane cultivation that will include a variety of metrics such as employment rates, livelihood diversification, and educational attainment. From this information I will suggest practices that afford a more resilient economic, agricultural, and social model for rural communities. The suggestions I put forth will not be palliative, but will instead be consistent with sustainable practices that foster capabilities, socioeconomic equality, and environmental stewardship. Resilient rural community development models avoid historic deforestation patterns and aid climate change mitigation, which in turn safeguards Brazil’s myriad economic sectors. Robust rural economies support national security by ensuring a healthy agricultural sector, avoiding unsustainable urban migration, and reducing poverty. The models and practices I suggest will inform policies and programs for Brazilian officials, agriculturalists, and conservationists to support rural communities, mitigate the impacts of climate change, and increase national security.

Megan Ward, Brigham Young University Social and Behavioral Sciences Little research has been done on the effect of parental media monitoring on a child’s thoughts and behaviors. This dearth of research is evident when considering the effect of parental media monitoring for a child who consumes Disney princess media. Research suggests that committed parents who heavily monitor their child’s media use are more likely to have a child who uses less media. The aim of this study is to garner a deeper understanding of the impact of parental media monitoring on a child’s stereotypical behaviors. Initial analyses showed a very strong correlation between how much a child identified with a particular princess and the number of female stereotypical traits. Namely, parents who reported that their children more closely identified with a princess showed gender stereotypical traits related to the types of toys they played with, the types of activities they participated in, and types of characteristics they took part in. Our analysis found the correlations to be especially strong when parents also reported low monitoring of their child’s media use, compared to parents who reported higher monitoring. Implications of these findings could influence children’s relationships with others. For example, children with more stereotypical behaviors may be less open to sharing, empathizing, and playing with other children who do not fit the gender stereotypes as accurately.

Ty Martin, Utah Valley University Social and Behavioral Sciences The purpose of this study was to explore the marital and personal life outcome of couples who either had in-law troubles or did not. Using Gottman’s (1999) core principles, this study explored the complex challenges young married couples faced when trying to turn toward their spouse while problematic relationships with their spouse’s parents created a wedge. Data was obtained via a random sample of 3,000 current and 7,000 former UVU students. Of the 11 percent who responded, 488 were in their first marriage. Two types of statistical analysis were used to explore the relationship between the married student’s relationship to their in-laws and other personal and marital factors.

Steven Clements, Utah Valley University Social and Behavioral Sciences The purpose of this study was to test the impact of having been on a dangerous call to EMS employee’s well-being. Two hypotheses were tested: First, suffering psychological symptoms from a dangerous call had no impact on their well-being; and second, suffering physical symptoms from a dangerous call had no impact on their well-being. In 2010, 7,000 state EMS employees were surveyed, yielding 668 completed surveys for this study.

Bryson Pope, Brigham Young University Social and Behavioral Sciences Purpose of the Project:

Chantelle Fitting, Brigham Young University Social and Behavioral Sciences Rebelliousness is often the product of an effort to express individualism and is an outlet for uniqueness (Imhoff & Erb, 2009); however, it can have very detrimental consequences. When a person strives to not conform to his or her family’s beliefs and values, familial relationships become strained, and the potential arises for the family to be torn apart. This nonconformity manifests itself through the beliefs a person has and the actions they take that are markedly different from those chosen by family members. The Nonconformist Assessment Scale (NCAS) is a ten question survey that is used to measure an individual’s inclination to rebel against his or her family unit. With the NCAS, we seek to discover indications of early rebelliousness, which are manifested through a person’s deviation from the family in areas such as weekly activities and personal interests. By detecting the seeds of nonconformity that arise in early life within the family, family therapists can intervene before more severe rebelliousness such as illegal activity, abandonment of core family values, or other dangerous behaviors emerge. Cronbach’s Alpha of the NCAS was found to be .7195, giving the test acceptable reliability. The Pearson bivariate correlation indicated that every item except item nine correlated positively with at least seven other items. The items loaded onto a single factor, and the variance explained by this factor was .7019. Thus the NCAS is a good indicator of nonconformity to familial values. However, the domains of actions and beliefs were not discernible as the items loaded only onto a single factor, so further research could be conducted that includes items where these domains are more easily separated from each other.

Joshua Matyi, University of Utah Social and Behavioral Sciences The Neural Efficiency Hypothesis (NEH) states that individuals with higher measured intelligence exhibit less neural activation on relatively simple tasks compared to those with lower intelligence (Haier et al., 1988). While the current NEH literature regarding electroencephalography (EEG) primarily focuses on amplitude measures, differences in peak latency relative to task demands could also indicate processing efficiency. The current study examined the relationship between intelligence and event-related EEG amplitudes and latencies during the third of three task conditions, a visual repetition paradigm. Full Scale IQ (FSIQ) scores from the Wechsler Adult Intelligence Scale III (WAIS-III; Wechsler, 1997) were collected on 30 participants, 18 of whom had sufficient numbers of EEG trials for further analysis (FSIQ: M = 111.56, SD = 13.28, range = 91 to 131). During EEG recording, participants were asked to respond to randomized line drawings representing one of three stimulus conditions from the previous two tasks: Repeated stimuli, Once-viewed, and Novel stimuli. Time-frequency analyses were conducted to identify peak phase-locked activity in the theta (4-7 Hz) and alpha (8-12 Hz) bands between 0 and 500 milliseconds post-stimulus. Results demonstrated no significant effects of IQ or stimulus condition on peak theta and alpha amplitudes. However, difference scores between Novel and Once-viewed conditions in peak theta latency showed a strong positive correlation with IQ (r[16] = .712, p < .01). These findings appear consistent with the NEH in suggesting that higher IQ individuals may process previously seen stimuli more efficiently than lower IQ individuals, as evidenced by shorter peak latencies relative to stimulus onset. A direction of future research could involve manipulating visual stimulus complexity, in order to isolate the effects of task complexity on peak latency, and potential interactions with IQ.

Michelle Hammon, Dixie State University Social and Behavioral Sciences A caregiver’s ability to meet their infant’s physical and emotional needs is important to development. Infants who are unable to get their needs met are at risk of developing an insecure attachment with their caregiver. The ability of the caregiver to empathize with and appropriately respond to the needs of their infant is dependent on the caregiver’s attachment representation. An online survey collected data from 112 college students. Participants completed the Experiences in Close Relationships-Revised (ECR-R) scale and the Interpersonal Reactivity Index (IRI). Insecure attachment representations were associated with the ability to empathize. Anxious-ambivalent attachment was positively associated with concern and distress and avoidant attachment were negatively associated with distress. These results suggest that attachment representations are important for the development of empathy.

Katherine Abarca, Westminster College Social and Behavioral Sciences The Hunger Games series has sold 50 million copies of the three books as of July 2012, has an impressive fandom, and has significant influence on popular culture. One of the many reasons for the success of the series is that its shocking story is set in a society eerily similar to the United States. The fictional country of Panem and its similarities to the United has caused it to gain interest in academia. Utilizing textual analysis, I examine how the fictional country of Panem is similar to present day United States in its inequality between classes and use of mechanisms of control. I also discuss how this cultural artifact affects our understanding of our society and how our society is reflected in the books. This research will expand the limited academic literature analyzing the Hunger Games. In addition, this research will focus on the different mechanisms of control in how they maintain inequalities between classes rather than stopping at analyzing the mechanisms themselves.

Kent Hinkson, Utah Valley University Social and Behavioral Sciences PTSD has become increasingly more concerning to the mental health world over the past few decades. A plethora of events (both acute and chronic) that serve as a triggering moment in the lives of those afflicted by this potentially debilitating condition are beginning to be identified more consistently. Yet, it continues to remain an area of concern because of the manner in which it affects nearly every aspect of its victim’s life.

William Ng, Utah Valley University Social and Behavioral Sciences This paper draws on leadership and behavioral theory in a public context to ascertain the full necessity of the sustainability officer to engender, sustain, and develop sustainability movements in higher education institutions and municipalities. As sustainability rises in awareness and demand from university and municipal stakeholders — influenced by political and educational discourse, the sustainability officer plays a vital role in conceptualizing, interpreting, and manifesting the abstract principles that stems from sustainability movements. Specifically, this study looks at the emergence of the sustainability officer, who they are, where they come from, what they do, and the outlook of future trends. Moreover, this paper looks at the structural positions of where sustainability officers fit in the organizational hierarchy and question whether they fall in line with contemporary political theory of public organizations. Furthermore, through interviews with Sustainability Managers/Coordinators/Directors, an intimate look into where they have been effective, where they could progress, and what they envision for themselves in the future has been garnished. Finally, these interviews manifest the establishment of the pragmatic connection between organizational theory and practice, allowing an exposition of the evolution of centralized sustainability leadership.

Derek Oliver, Dixie State University Social and Behavioral Sciences The use of birth interventions has been steadily increasing over the past several decades based on largely non-medical factors. It is thought that the various birth interventions (i.e. forceps, vacuum extraction, epidural, etc.), pitocin use, the mother’s attachment and psychological constructs during pregnancy are related to the incidences of neurodevelopmental disorders. Thus, the current study attempts to understand the association between birth intervention and the development of neurodevelopmental disorders. Three hundred mothers of children between one and five years of age were recruited using social media, flyers and phone calls. Mothers provided access to their medical records of the birth of their child as well as incidences of neurodevelopmental disorders in their children. Mother’s hospital records were obtained to determine length of pregnancy, duration of labor and rate and duration of pitocin use. It is expected that there will be a significant correlation between developmental disorders and interventions broadly. Further, it is expected that pitocin use will be positively correlated with incidences of autism.

Rebecca Holland, Brigham Young University Social and Behavioral Sciences Dialectical Quichua throughout Ecuador faces disappearance through the development of Quichua Unificado, a standardized form of Quichua used the bilingual school system. This form of Quichua was created in hopes that introducing a standardized orthography would help bilingual schools effectively address the Quichua language loss that is pervasive throughout the country. However, as the language steps beyond its intended bounds of being a written language and moves toward replacing dialectical Quichua as a spoken language, it is evident that this revitalization movement is progressing at a great cost. Original ethnographic research in the Napo Valley of Ecuador asserts that this movement is ineffectual at reversing the Quichua language loss in this area, and may in fact prove fatal to the future of spoken dialectical Quichua.

Andrew Fletcher, Utah Valley University Physical Sciences Springville, Utah, is known for its high water table and many freshwater wetlands and springs, which gave rise to the name of the city. Flooding of barns is a common problem among farmers in western Springville, which is just east of Utah Lake. These frequent barn floods are anecdotally linked to high-intensity precipitation events and the common use of flood irrigation. The objective of this study is to determine the cause of barn flooding and to make recommendations for mitigation of barn flooding for individual farmers with whom we are working in this area. The objective is being addressed first by using ArcGIS to determine the watershed of each barn and the NRCS (Natural Resource Conservation Service) Web Soil Survey to map hydrologic soil groups within each watershed. Results from the larger-scale Web Soil Survey will be supplemented with measurements of soil hydraulic conductivity using the SoilMoisture Equipment Model 2800K1 Guelph Permeameter. The above data will be used in the NRCS Curve Number Method to estimate the volume of surface runoff expected in a 100-year 24-hour precipitation event. The objective is also being addressed by installing shallow, hand-augured wells for monitoring the depth to the water table during high-intensity precipitation events and flood irrigation events. The results will be used to develop recommendations for a combination of (1) installation of French drains for diversion of stormwater (2) modification of current irrigation methods (3) pumping and diversion of groundwater. Results and specific recommendations for individual farmers will be presented at the meeting.

Nils Otterstrom, Brigham Young University Physical Sciences Filtered photodiodes show potential as inexpensive laser wavelength meter. Photocurrents are measured digitally. The photocurrent is digitized using externally controlled integration times to achieve the highest precision possible from the digital to analog converters on the photosensor chip. Using an algorithm we’ve developed and calibrated intensity curves, we can precisely calculate wavelength from the output of the different photodiodes. Limitations due to etaloning from reflections off of the surfaces of the filters were analyzed and effectively mitigated, allowing the device to achieve high precision with a stability of 0.102 nm over several hours.
