The Self In ‘Fieldwork’: A Methodological Concern, Christie L. Fox, Beverly Stoeltje, Stephen Olbrys

English Faculty Publications

As concepts of reflexivity and postcolonial perspectives have advanced our understandings of the way we represent those we study, they have also introduced a consciousness of the role of the self in research. This article reviews the history of the field of folklore with regard to the method of obtaining data or texts and demonstrates that collecting material contrasts with the practice of conducting research in the field. Pointing to a moment of transition, it shows that theories of folklore had to undergo significant change before methods of research would acknowledge the identity of the fieldworker and its significance.

Potential For Aquifer Storage And Recovery In Box Elder And Cache Counties, Mariush Kemblowski, Tom Lachmar, Richard Peralta

Civil and Environmental Engineering Faculty Publications

Groundwater artificial storage and recovery (ASR) has become a favorable means in the arid west to store water produced in excess of need during winter months for use in drier times of the year. ASR may be accomplished by injection of suitable water into the groundwater system via wells to be pumped out later, or by recovery of seepage via wells from surface water impoundments or infiltration networks. This report will present pertinent hydrogeologic information for the location of an artificial groundwater storage and recovery project in Utah's northeastern Box Elder County.

Surface Energy Balance Affects Gas Exchange Of Three Shrub Species, Thayne Montague, Roger Kjelgren, Larry Rupp

Plants, Soils, and Climate Faculty Publications

We investigated the energy balance of vegetative and nonvegetative surfaces and gas exchange for 3 shrub species growing over each surface. During a 1-week period, incoming short-wave radiation, surface and soil temperature, and soil heat flux for turf and pine-bark mulch surfaces were gathered. Air temperature and relative humidity at 2 heights over each surface were also measured. Mulch surface and air temperatures were warmer and soil temperature below mulch was cooler than turf throughout each day. Relative humidity varied with height above turf, but each height was comparable over mulch. For the majority of each day, soil heat flux …

Habitat Conservation Plan For Utah Prairie Dogs In Iron County, Utah, Iron County Commission, Utah Division Of Wildlife Resources

All U.S. Government Documents (Utah Regional Depository)

The Utah prairie dog is a federally threatened species that occurs only in southwestern Utah. A large proportion (65%) of the total population of Utah prairie dogs occurs in Iron County, and a high percentage (86%) of those (2,456/2,843 in 1997) occur on privately owned lands. Population growth in Iron County has averaged more than 6% over the last five years, and is expected to continue at least at the same pace, and possibly as high as 10% (Colgan 1997). The increase in both residential and commercial development in Iron County has been the greatest in Cedar City, but has …

Development And Evaluation Of A Noninvasive Hemoglobinometer, Shonn P. Hendee, Dwayne R. Westenskow

Utah Space Grant Consortium

Measurement of hemoglobin concentration is among the most common clinical procedures. It is necessary in screening for anemia and is a means of providing a general assessment of physical well-being. Current methods for measuring hemoglobin concentration are invasive, requiring blood access. This paper describes a novel technique for measuring hemoglobin concentration noninvasively. The method takes advantage of the unique optical properties of hemoglobin to make the measurement. A vascularized tissue bed is transilluminated with a narrow linewidth optical source at an isobestic wavelength of oxy- and deoxy-hemoglobin. The transmitted light intensity is measured as the tissue is compressed, which causes …

Plant Growth Conditions In Spaceflight And Pathogenicity Of Microbes, Binh Huynh, Anne J. Anderson

Utah Space Grant Consortium

In spaceflight conditions, plants are subjected to a variety of environmental stresses which may promote microbial growth and potential pathogenicity. Among the changes that may occur in the plant is a decrease in freely available carbohydrates, resulting in the microbe having to look for alternative carbon sources. A seed-borne fungal endophyte, an Acremonium species, was identified as the symptom-causing agent in Super Dwarf seedlings grown in a spaceflight mission in 1995. Plants bearing the endophyte grew without symptoms in the greenhouse in open conditions. The isolated Acremonium grew well on different carbohydrates available in wheat leaf apoplastic fluids as well …

Influence Of Food Resources And Temperature On The Distribution And Energy Balance Of Bear Lake Sculpin, Cottus Extensus, Wayne A. Wurtsbaugh, Clyde Lay

Watershed Sciences Faculty Publications

Changes in the abundance, diet, and daily ration of adult and sub-adult Bear Lake sculpin (Cottus extensus) were investigated seasonally along a littoral to profundal transect in Bear Lake to determine if or when sculpin were food limited. During different seasons, sculpin migrated inshore or offshore. These were most pronounced for age 1 + sculpin, 35-55 mm in length. This age class was most abundant in the littoral zone, particularly in August. The migrations of age two and older sculpin were less pronounced, and most of these fish were located in the profundal zone (>30 m). The …

Optimizing Conjunctive Water Use For Sustainable Production: Tools For The Management Spectrum, Richard C. Peralta, Shengjun J. Wu, H. J. Morel-Seytoux, Fernando Chanduvi

Civil and Environmental Engineering Faculty Publications

Making best use of water resources requires coordinating use of groundwater and surface waters--conjunctive use. Conjunctive water management is important on the regional (watershed or aquifer), water district and field scales. Goals might differ for the different administrative levels. A regionally optimal water management strategy is not necessarily optimal for water district managers and individual farmers. Interactions between levels are affected by laws, regulations, traditions and public pressure. To help each organizational level develop water management strategies that best achieve its goals, computer simulation/optimization (S/O) models are useful. Such S/O models couple water flow and transport simulation techniques with formal …

Expression, Purification, And Characterization Of Nonstructural Protein 2 (Ns2) Of Bluetongue Virus Serotype 17, Hai Lin

Biology

The NS2 protein of bluetongue virus (BTV) serotype 17 (B17) was expressed in large scale as a Glutathione-S-Transferase (GST) fusion protein in E. coli cells. The size of the expressed NS2/GST fusion protein was about 68 kilodaltons (kDa) when analyzed by sodium dodecylsulfate polyacrylamide gel electrophoresis (SDS-PAGE). This is equal to the sum of the predicted size from the deduced amino acid sequence of the NS2 protein (41 kDa) and the known mass of the GST protein (27 kDa). The NS2/GST fusion protein was purified by absorption to glutathione-conjugated agarose beads (G-beads), and then analyzed on western blots by two …

Phytotoxicity Of Pseudomonas Chlororaphis Strain O6: Role Of Phenazines And Implications For Biocontrol, Elizabeth Thomas

Biology

Phenazines, the water-soluble pigments produced naturally by bacteria with distinct antimicrobial properties, have been implicated in the biological control of several plant diseases. Pseudomonas chlororaphis strain O6, obtained from the rhizosphere of wheat, is known to produce at least three different phenazines, which include phenazine-1-carboxylic acid, 2-hydroxyphenazine-1-carboxylic acid, and 2-hydroxyphenazine. A field trial conducted in the fall of 1994 to test the biocontrol properties of O6 indicated that this strain inhibited wheat seed germination, which led me to hypothesize that phenazines cause phytotoxicity. Mutants of O6 created by Tn5 lux insertion (Phz^- mutants) that did not produce the pigments …

The Development Of A Bluetongue Virus Diagnostic Assay Using Heterologously Expressed Structural Protein Vp7 And Nonstructural Protein Ns2, Mary Anne Wise

Biology

The S1 gene of bluetongue virus that encodes major inner core protein, VP7, was cloned and expressed in the Thiofusion Expression Vector System. The VP7-thioredoxin protein was then partially purified. The nonstructural protein NS2 having previously been cloned into the GST Gene Fusion Vector System was also expressed and purified as NS2-GST fusion protein. These two viral proteins were used together in an immunologic detection assay. This assay was able to distinguish between bluetongue virus infected, vaccinated and noninfected sheep. Assayed serum samples of infected sheep, cattle, bison, and goats showed detectable antibodies to both VP7 and NS2, whereas vaccinated …

Improved Culture Of Tumor-Infiltrating Lymphocytes, Roger A. Burger

Biology

Adoptive immunotherapy using in vitro expanded tumor-infiltrating lymphocytes (TIL) continues to be the subject of research and clinical trials for the treatment of cancer. However, the culture methods used to expand large numbers of TIL are limited and often ineffective. In this study using murine TIL, the level of in vitro expansion, expression of adhesion molecules and infiltration into tumors after infusion was evaluated. A comparison was made between lymphocyte culture fluid (LCF), a bovine plasma-based medium, and a bovine serum-based medium (SCM) as the culture media. Because plasma-based media lack the lymphocyte inhibitory factors associated with serum-based media, it …

Sensitizing Resin Acids In Aerosol Derived From Rosin Flux Used In Electronics Soldering: Molecular Mechanistic Studies In Resin Acid/Protein Hapten Formation, Philip A. Smith

Biology

Exposure to rosin and its resin acid constituents is associated with dermal and pulmonary sensitization. Methodologies to detect resin acid compounds in aerosol from heated rosin flux included air filtration, filter extraction, and gas chromatography/mass spectrometry. Various resin acids were seen in aerosol collected under field conditions, and in the laboratory. The predominant resin acid recovered was dehydroabietic acid, with lower levels of abietic acid and oxidized resin acids, which included 7-oxodehydroabietic, 15-hydroxydehydroabietic, and 7-hydroxydehydroabietic acids. Mass balance experiments with a soldering iron and liquid rosin flux showed most of the nonvolatile mass in unheated flux to be filtrable following …

The Reproductive Biology And Ecology Of Penstemon Harringtonii (Scrophulariacea): Implications For Conservation, Romaine L. Nielson

Biology

I examined the reproductive biology of Harrington's Penstemon, a rare endemic of the Colorado Plateau, to obtain information important to conservation efforts for this species. I applied four different hand-pollination treatments to P. harringtonii's flowers and found that it is partially self-compatible but sets more fruits when cross-pollinated by insects. Plant placement in new populations may be important because pollinators are more attracted to dense floral resources. Thus, the fruit set of plants within a 450 cm² area was compared with those at least 3 m apart. Unexpectedly, aggregated plants produced 16.1 fruits per plant compared to 21.0 …

Identification And Characterization Of Chromosome-Specific Randomly Amplified Polymorphic Dna (Rapd) Markers In Triticum Aestivum-Aegilops Caudata Addition Lines, Lihua Sun

Biology

DNA markers for Aegilops caudata C-genome chromosomes will be useful in linkage studies of disease resistance and alien gene introgression, e.g., these markers can be tools in gene mapping and plant breeding. However, the individual chromosomes have not been characterized at the molecular level in Ae. Caudata. The objective of this study was to identify and characterize DNA markers for Ae. caudata chromosomes using the randomly amplified polymorphic DNA (RAPD) technique. DNA samples from Ae. caudata, Triticum aestivum (bread wheat), amphiploid of T. aestivum X Ae. caudata, and six disomic addition lines of T. aestivum carrying …

Factors Concerning The Conservation Of A Rare Shale Endemic Plant: The Reproductive Ecology And Edaphic Characteristics Of Penstemon Debilis (Scrophulariaceae), Amy L. Mcmullen

Biology

The management of a rare, edaphic endemic plant species requires an understanding of the ecological setting and processes that contribute to its restriction. Included in the ecological processes is a set of biotic characters associated with the reproductive ecology, including its breeding system, pollination vectors, and germination requirements. The geologic and soil setting of the plant must also be characterized in order to understand the plant's restriction to the substrate. These issues were addressed by this study of the rare endemic Penstemon debilis O'Kane and Anderson (Scrophulariaceae). Penstemon debilis consists of six populations that occur on talus slopes of the …

Phylogenetic Characterization Of Endosymbionts In Psyllids (Hemiptera: Sternorrhyncha), Allen W. Spaulding

Biology

Most sternorrhynchan insects harbor endosymbiotic bacteria in specialized cells (bacteriocytes) near the gut, which provide essential nutrients for hosts. In lineages investigated so far with molecular methods (aphids, mealybugs, whiteflies), endosymbionts apparently have arisen from independent infections of common host ancestors and cospeciated with their hosts. Some endosymbionts also exhibit putatively negative genetic effects from their symbiotic association. In this study, the identity of endosymbionts in one major sternorrhynchan lineage, psyllids (Psylloidea), was investigated to determine their position in eubacterial phylogeny and relationship to other sternorrhynchan endosymbionts. Small-subunit ribosomal RNA genes (16S rDNA) from bacteria in three psyllid species (families …
