Polymer Microfluidic Devices For Bioanalysis, Xuefei Sun Feb 2009

Polymer Microfluidic Devices For Bioanalysis, Xuefei Sun

Theses and Dissertations

Polymeric microchips have received increasing attention in chemical analysis because polymers have attractive properties, such as low cost, ease of fabrication, biocompatibility and high flexibility. However, commercial polymers usually exhibit analyte adsorption on their surfaces, which can interfere with microfluidic transport in, for example, chemical separations such as chromatography or electrophoresis. Usually, surface modification is required to eliminate this problem. To perform stable and durable surface modification, a new polymer, poly(methyl methacrylate-co-glycidyl methacrylate) (PGMAMMA) was prepared for microchip fabrication, which provides epoxy groups on the surface. Whole surface atom transfer radical polymerization (ATRP) and in-channel ATRP approaches were employed to …

Survival Analysis With High-Dimensional Covariates: An Application In Microarray Studies, David Engler, Yi Li Feb 2009

Survival Analysis With High-Dimensional Covariates: An Application In Microarray Studies, David Engler, Yi Li

Faculty Publications

Use of microarray technology often leads to high-dimensional and low-sample size (HDLSS) data settings. A variety of approaches have been proposed for variable selection in this context. However, only a small number of these have been adapted for time-to-event data where censoring is present. Among standard variable selection methods shown both to have good predictive accuracy and to be computationally efficient is the elastic net penalization approach. In this paper, adaptations of the elastic net approach are presented for variable selection both under the Cox proportional hazards model and under an accelerated failure time (AFT) model. Assessment of the two …

Desiccation Survival In An Antarctic Nematode: Molecular Analysis Using Expressed Sequenced Tags, Byron J. Adams, Bishwo N. Adhikari, Diana H. Wall Feb 2009

Desiccation Survival In An Antarctic Nematode: Molecular Analysis Using Expressed Sequenced Tags, Byron J. Adams, Bishwo N. Adhikari, Diana H. Wall

Faculty Publications

Background: Nematodes are the dominant soil animals in Antarctic Dry Valleys and are capable of surviving desiccation and freezing in an anhydrobiotic state. Genes induced by desiccation stress have been successfully enumerated in nematodes; however we have little knowledge of gene regulation by Antarctic nematodes which can survive multiple environmental stresses. To address this problem we investigated the genetic responses of a nematode species, Plectus murrayi, that is capable of tolerating Antarctic environmental extremes, in particular desiccation and freezing. In this study, we provide the first insight into the desiccation induced transcriptome of an Antarctic nematode through cDNA library construction …

Evaluation Of Total Runoff For The Rio San Pedro Sub-Basin (Nayarit, Mexico) Assessing Their Hydrologic Response Units Jan 2009

Evaluation Of Total Runoff For The Rio San Pedro Sub-Basin (Nayarit, Mexico) Assessing Their Hydrologic Response Units

Journal of Spatial Hydrology

The Rio San Pedro sub-basin runoff was estimated using the curve number method (NRCS-CN) applied to hydrologic response units (HRU’s), derived from remote sensing and GIS analysis. The sub-basin (around 2900 km2) was delineated from digital elevation models (DEM), that also were used to obtain the slopes in the study area. A landscape characterization (overall accuracy > 80%), based on Landsat ETM+ imagery, was obtained using standard classification methods, and together with a rainfall data series, were the input information for the sub-basin discretization in HRU’s and the runoff calculation. Seventeen HRU’s were obtained, that can be arranged in …

Giuh Based Transfer Function For Gomti River Basin Of India Jan 2009

Giuh Based Transfer Function For Gomti River Basin Of India

Journal of Spatial Hydrology

Geomorphologic instantaneous unit hydrograph (GIUH) can be used as a transfer function for modeling the transformation of excess rainfall into surface runoff, in which excess rainfall is an excitation (i.e. production function) to the hydrologic system. These models can be used to predict / forecast the temporal variation of the surface runoff at the outlet of ungauged basin, which is useful in the hydrologic / environmental engineering applications. The present study deals with the geomorphometric investigation and provides an efficient solution approach to derive the GIUH based transfer function and thus geomorphologic unit hydrograph (GUH) for the basin. Since, Gomti …

Diversity Of Insects From The Vespidae Family In Three Ecological Niches (Forest, Forest Border, And Agricultural Area) In Six Communities In The Coroico And Coripata Municipalities, Department Of La Paz, Edwin Zapata Mayta Jan 2009

Diversity Of Insects From The Vespidae Family In Three Ecological Niches (Forest, Forest Border, And Agricultural Area) In Six Communities In The Coroico And Coripata Municipalities, Department Of La Paz, Edwin Zapata Mayta

Theses and Dissertations

The Vespidae family (order Hymenoptera) is comprised of 4500 species of wasps in 268 genera and 7 subfamilies. These wasps prey upon a wide range of insects, including Lepidopteran caterpillars. Because of their low prey specificity, the use of Vespid wasps in biological control programs is limited. However, in their natural habitat, they play a role in controlling populations of some pest species. This study was conducted in six different communities in the department of La Paz within the municipalities of Coroico and Coripata. Three ecological niches were selected in each community: 1) the forest, 2) the edge of the …

An Empirical And Consumer Psychology Analysis Of Trademark Distinctiveness, Thomas R. Lee, Eric D. Derosia, Glenn L. Christensen Jan 2009

An Empirical And Consumer Psychology Analysis Of Trademark Distinctiveness, Thomas R. Lee, Eric D. Derosia, Glenn L. Christensen

Faculty Publications

This article analyzes the taxonomy of trademark distinctiveness that has long been endorsed in the courts and scholarly commentary. This distinctiveness scale is routinely justified on the basis of an assumption about consumer psychology: that consumers perceive suggestive, arbitrary, or fanciful marks as source-indicating, but see descriptive marks as "merely descriptive." Although this core premise of trademark law is a fundamental matter of consumer psychology, it has never been subjected to scrutiny under the light of consumer psychology theory and empirical analysis. We offer a consumer psychology model for questioning the law of distinctiveness (or "source indication") and then test …

Demonstration Of Microcantilever Array With Simultaneous Readout Using An In-Plane Photonic Transduction Method, Seunghyun Kim, Gregory P. Nordin, Ryan Anderson, Weisheng Hu, Yusheng Qian, Jiguo Song, Jong Wook Noh

Faculty Publications

We demonstrate a microcantilever array with an in-plane photonic transduction method for simultaneous readout of each microcantilever. The array is fabricated on a silicon-on-insulator substrate. Rib waveguides in conjunction with a compact waveguide splitter network comprised of trench-based splitters and trench-based bends route light from a single optical input to each microcantilever on the chip. Light propagates down a rib waveguide integrated into the microcantilever and, at the free end of the microcantilever, crosses a small gap. Light is captured in static asymmetric multimode waveguides that terminate in Y-branches, the outputs of which are imaged onto an InGaAs line scan …

Nps' Perceptions Of Disaster Preparedness Education: Quantitative Survey Research, Milada Tichy, A. Elaine Bond, Renea L. Beckstrand, Barbara Heise

Faculty Publications

Nurse practitioners need to be effective in responding to large-scale natural and man-made disasters. However, disaster core competencies for NPs are largely nonexistent. The purpose of this study was to assess NPs' level of disaster preparedness and determine how NPs acquired knowledge about disaster preparation. Findings suggest that a consistent national NP curriculum for disaster preparedness, including communication with other disaster agencies, is needed. With proper education, NPs can play a major role in disaster management.

Birth Language Attrition And Reacquisition In Russian Adoptees, Avram J. Lyon Jan 2009

Birth Language Attrition And Reacquisition In Russian Adoptees, Avram J. Lyon

Russian Language Journal

The wave of adoption from Russia and other countries of the former Soviet Union has brought a large number of incomplete Russian speakers into the United States; over 71,000 orphans from Russia, Ukraine, Kazakhstan, and Belarus have been issued United States entry visas since 1992 (U.S. Department of State 2007 and 2009; Ruggiero 2007). This is part of a larger trend toward international adoption, amounting to several hundred thousand children in the past decades. Children adopted by American families experience a radical reduction in birth language exposure and must quickly acclimate to and become proficient in the language of the …

“And The Word Was Made Flesh”: A Latter-Day Saint Exegesis Of The Blood And Water Imagery In The Gospel Of John, Eric D. Huntsman Jan 2009

“And The Word Was Made Flesh”: A Latter-Day Saint Exegesis Of The Blood And Water Imagery In The Gospel Of John, Eric D. Huntsman

Studies in the Bible and Antiquity

Critical to understanding the widespread symbolism and imagery pointing to Jesus Christ in the New Testament is an exegetical grasp of the content--that is, an understanding of the historical, literary, and theological context of the language. The image of water recurs frequently throughout the New Testament Gospels as a symbol of the Savior's purity, cleansing power, true doctrine, and so forth. Similarly, blood is used often to reflect the sacred mission of Christ and the price of our salvation. This article investigates this imagery, particularly as used by Apostle John, to explain the significance of the Savior's mission in mortality …

Social Ties And Cardiovascular Function: An Examination Of Relationship Positivity And Negativity During Stress, Wendy C. Birmingham, Bert N. Uchino, Timothy W. Smith, Kathy C. Light, David M. Sanbonmatsu

Faculty Publications

The quality and quantity of one’s relationships have been reliably linked to morbidity and mortality. More recently, studies have focused on links between relationships and cardiovascular reactivity as a physiological mechanism via the stress-buffering hypothesis. However, not all social relationships are consistently positive which points to the importance of a more comprehensive examination of relationship that includes negative qualities. In this study, we manipulated relationship positivity and negativity with an experimenter and examined its influence on cardiovascular reactivity. Results revealed that relationship positivity was associated with lower systolic blood pressure (SBP) reactivity for men and women. Relationship negativity, on the …

Tpack Development In Science Teaching: Measuring The Tpack Confidence Of Inservice Science Teachers, Charles R. Graham, Nicolette Burgoyne, Pamela Cantrell, Leigh Smith, Larry St. Clair, Ron Harris

Faculty Publications

Knowledge related to the effective use of educational technologies has become widely recognized as an important aspect of an educator’s knowledge-base for the 21st Century (ISTE, 2008; National Council for Accreditation of Teacher Education, 1997; Partnership for 21st Century Skills, 2003). Early in the history of educational technology, educators were taught in technology classes that focused primarily on technology skills independent from the pedagogical or content courses (Graham, Culatta, Pratt, & West, 2004; Hargrave & Hsu, 2000; Willis & Mehlinger, 1996). Educators soon recognized that technology skills alone did not serve them well because one could know how to operate …

Hardware Accelerated Sequence Alignment With Traceback, Scott Lloyd, Quinn O. Snell Jan 2009

Hardware Accelerated Sequence Alignment With Traceback, Scott Lloyd, Quinn O. Snell

Faculty Publications

Biological sequence alignment is an essential tool used in molecular biology and biomedical applications. The growing volume of genetic data and the complexity of sequence alignment present a challenge in obtaining alignment results in a timely manner. Known methods to accelerate alignment on reconfigurable hardware only address sequence comparison, limit the sequence length, or exhibit memory and I/O bottlenecks. A space-efficient, global sequence alignment algorithm and architecture is presented that accelerates the forward scan and traceback in hardware without memory and I/O limitations. With 256 processing elements in FPGA technology, a performance gain over 300 times that of a desktop …

Using A Mathematical Model Of Cadherin-Based Adhesion To Understand The Function Of The Actin Cytoskeleton, J. C. Dallon, Elijah Newren, Marc Hansen Jan 2009

Using A Mathematical Model Of Cadherin-Based Adhesion To Understand The Function Of The Actin Cytoskeleton, J. C. Dallon, Elijah Newren, Marc Hansen

Faculty Publications

The actin cytoskeleton plays a role in cell-cell adhesion but its specific function is not clear. Actin might anchor cadherins or drive membrane protrusions in order to facilitate cell-cell adhesion. Using a mathematical model of the forces involved in cadherin-based adhesion we investigate its possible functions. The immersed boundary method is used to model the cell membrane and cortex with cadherin binding forces added as linear springs. The simulations indicate that cells in suspension can develop normal cell-cell contacts without actin-based cadherin anchoring or membrane protrusions. The cadherins can be fixed in the membrane or free to move and the …

Field Identification Of Myotis Yumanensis And Myotis Lucifugus: A Morphological Evaluation, Thomas J. Rodhouse, Shonene A. Scott, Patricia C. Ormsbee, Jan M. Zinck

Western North American Naturalist

Myotis lucifugus and Myotis yumanensis are 2 species of bats subject to potentially high rates of misidentification because they are often difficult to differentiate in the hand under field conditions. We tested the utility of a suite of external morphological characteristics frequently cited in regional keys to differentiate the 2 species in the field. Forearm length, dorsal pelage sheen, ear color, and forehead slope were examined from 101 bats captured in central Oregon during 2002–2003. Post hoc genetic analysis was performed on tissue samples collected from the 101 bats to confirm identification. Forearm lengths overlapped considerably between species. Only 18% …

Reproduction By June Sucker In A Refuge Population: Successful Spawning In A Lake Habitat, Eric J. Billman Dec 2008

Reproduction By June Sucker In A Refuge Population: Successful Spawning In A Lake Habitat, Eric J. Billman

Western North American Naturalist

The June sucker (Chasmistes liorus) is an endangered lake sucker endemic to Utah Lake, Utah. As part of recovery actions, June suckers were introduced into Red Butte Reservoir, Utah, as a wild grow-out site. Since their introduction, June suckers have successfully reproduced in Red Butte Reservoir, producing a large population in this refuge. I used passive egg collectors (egg traps and nets) and observational surveys to determine the location of spawning sites within the reservoir, and larval light trapping to determine successful recruitment (i.e., egg survival through larval swim-up) at these sites. Eggs were collected between 18 June …

"Pando" Lives: Molecular Genetic Evidence Of A Giant Aspen Clone In Central Utah, Jennifer Dewoody, Carol A. Rowe, Valerie D. Hipkins, Karen E. Mock Dec 2008

"Pando" Lives: Molecular Genetic Evidence Of A Giant Aspen Clone In Central Utah, Jennifer Dewoody, Carol A. Rowe, Valerie D. Hipkins, Karen E. Mock

Western North American Naturalist

While clones of trembling aspen (Populus tremuloides, Michx.) in the Intermountain West of North America are expected to be large, one putative genet in central Utah, identified from morphological evidence, has garnered particular attention for its size, even gaining the nickname "Pando" (Latin for "I spread"). In order to determine if a single genetic individual coincides with the morphological boundary of "Pando," we sampled 209 stems on a 50-m grid throughout the putative clone for analysis at 7 microsatellite loci. We have identified a single genetic entity concurrent with that described from morphological characteristics. Spatial analyses indicate that the …

Distribution, Abundance, And Genetic Population Structure Of Wood River Sculpin, Cottus Leiopomus, Kevin A. Meyer, Daniel J. Schill, Matthew R. Campbell, Christine C. Kozfkay Dec 2008

Distribution, Abundance, And Genetic Population Structure Of Wood River Sculpin, Cottus Leiopomus, Kevin A. Meyer, Daniel J. Schill, Matthew R. Campbell, Christine C. Kozfkay

Western North American Naturalist

The Wood River sculpin Cottus leiopomus is endemic to the Wood River Basin in central Idaho and is a nongame species of concern because of its limited distribution. However, status and genetic population structure, 2 factors often central to the conservation and management of species of concern, have not been assessed for this species. We used backpack electrofishers to survey streams that were small enough (i.e., <10 m wide) to collect quantitative distribution and abundance data for Wood River sculpin, and we used mitochondrial DNA control region sequencing to investigate the distribution of genetic variation across the species' range. Of the 102 study sites surveyed, 20 sites (20%) had Wood River sculpin present, including 50%, 15%, and 0% of the sites predicted a priori to contain, possibly contain, or not contain the sculpin, respectively. Native redband trout Oncorhynchus mykiss gairdneri were present at 21 study sites, including 18 of the 20 sites that contained Wood River …
