Relationship Of Theoretical Patch Climatology To Polar Cap Patch Observations, M. D. Bowline, Jan Josef Sojka, Robert W. Schunk

All Physics Faculty Publications

During a southward orientation of the interplanetary magnetic field (IMF), patches are often observed moving antisunward across the polar cap. In saying “patches” we refer to structures in which the F region electron densities are enhanced relative to lower background levels; we do not in this paper consider patches which are observed optically (see J. J. Sojka et al., Ambiguity in identificiation of polar cap F region patches, submitted to the Journal of Atmospheric and Terrestrial Physics, 1995). The patches can be modeled by a process which involves the “chopping up” of the tongue of ionization (TOI) [Sojka …

Simulated Growth And Production Of Endangered Snake River Sockeye Salmon: Assessing Management Strategies For The Nursery Lakes, Chris Luecke, Wayne A. Wurtsbaugh, Phaedra E. Budy, H. P. Gross

Watershed Sciences Faculty Publications

We examined the potential of employing a series of lake management strategies to enhance production of endangered Snake River sockeye salmon (Oncorhynchus nerka) in its historical nursery lakes in central Idaho. We used a combination of limnological sampling, experimentation, and simulation modeling to assess effects of lake fertilization and kokanee reduction on growth and survival of juvenile sockeye salmon. Juvenile sockeye salmon from a broodstock of this endangered species are being introduced into the lakes from 1995 to 1998. Results of our analyses indicated that several lakes were suitable for receiving broodstock progeny. Field experimentation and simulation modeling indicated that …

Albumin Affinity Biomaterial Surfaces, James R. Keogh, John W. Eaton

Cells and Materials

Recently, considerable progress has been made in designing biomaterial surfaces which possess enhanced albumin affinity. Two derivatization methods for producing albumin binding biomaterial surfaces, based on an albumin affinity dye, cibacron blue, have been developed. Both surface derivatization methods were found to enhance the binding of albumin to an implant grade polyetherurethane. Evaluations of the enhanced albumin affinity demonstrated the binding to be both selective and reversible. Surfaces having such enhanced albumin affinity were found to be minimally thrombogenic and to discourage the adhesion of bacteria which might otherwise cause device-centered infections. We conclude that albumin affinity surfaces, such as …

Waste-Wood-Derived Fillers For Plastics, Brent English, Craig M. Clemons, Nicole Stark, James P. Schneider

Aspen Bibliography

Filled thermoplastic composites are stiffer, stronger, and more dimensionally stable than their unfilled counterparts. Such thermoplastics are usually provided to the end-user as a precompounded, pelletized feedstock. Typical reinforcing fillers are inorganic materials like talc or fiberglass, but materials derived from waste wood, such as wood flour and recycled paper fiber, are also effective as fillers. The goal of this project was to generate commercial interest in using waste-wood–paper-derived fillers (WPFs) to reinforce thermoplastics. The research strategy was twofold: developmental research and outreach. Specific objectives were (1) to improve wastepaper fiber preparation, feeding, and compounding methods, and optimize composite performance, …

Impact Of The Spirit Iii Sensor Design On Algorithms For Background Removal, Object Detection, And Point Source Extraction, Mark F. Larsen, Joseph J. Tansock Jr., Garth Sorenson, Dean S. Garlick, Steven S. Hansen

Space Dynamics Laboratory Publications

This paper describes background removal, point source detection, and position and irradiance extraction data processing algorithms that have been developed for the Spatial Infrared Imaging Telescope (SPIRIT) III design. The SPIRIT III sensor is the primary instrument on the Midcourse Space Experiment (MSX) satellite and is scheduled for launch in early 1996. The sensor consists of an off-axis reimaging telescope, and, among other instruments, a six-band scanning radiometer that covers the spectrum from midwave infrared to longwave infrared. The radiometer has five arsenic-doped silicon (Si:As) focal plane detector arrays with 8 x 192 pixels. The angular separation between adjacent pixels …

Fate Of Biological Control Introductions: Monitoring An Australian Fungal Pathogen Of Grasshoppers In North America, Michael J. Bidochka, Scott R. A. Walsh, Mark E. Ramos, Raymond J. St. Leger, Julie Cl Silver, Donald W. Roberts

Biology Faculty Publications

In North America there are two generally recognized pathotypes (pathotypes 1 and 2) of the fungus Entomophaga grylli which show host-preferential infection of grasshopper subfamilies. Pathotype 3, discovered in Austra- lia,hasabroadergrasshopperhostrangeandwasconsidered to be a good biocontrol agent. Between 1989 and 1991 patho- type3wasintroducedattwofieldsitesinNorthDakota.Since resting spores are morphologically indistinguishable among pathotypes, we used pathotype-specific DNA probes to con- firm pathotype identification in E. grylli-infected grasshop- pers collected at the release sites in 1992, 1993, and 1994. In 1992, up to 23% of E. grylli-infected grasshoppers of the subfamilies Melanoplinae, Oedipodinae, and Gomphocerinae were infected by pathotype 3,with no infections >1 km …

Stress Corrosion And Stress Induced Surface Morphology Of Epitaxial Films, Michael Grinfeld

Scanning Microscopy

In addition to several new predictions, the general theory of thermodynamic stability of heterogeneous systems with rearrangement has allowed us to understand the roots of several experimental and theoretical results of the past. One of them is an outstanding paper of Asaro and Tiller on stress corrosion cracking by surface diffusion published two decades ago. We compare results of Asaro and Tiller with conclusions of thermodynamic theory of solids with rearrangement and develop some Asaro-Tiller results in the directions dictated by the needs of thin films technology and experiment. A surface diffusion model in a prestressed elastic solid is studied …

Comparative Scanning, Transmission And Atomic Force Microscopy Of The Microtubular Cytoskeleton In Fenestrated Liver Endothelial Cells, Filip Braet, Ronald De Zanger, Wouter Kalle, Anton Raap, Hans Tanke, Eddie Wisse

Scanning Microscopy

Endothelial fenestrae control the exchange of fluids, solutes and particles between the sinusoidal lumen and the microvillous surface of the parenchymal cells. Fenestrae have a critical dimension in the order of 150-200 nm, making it necessary to use microscopes with a resolution better than the light microscope. Comparative whole-mount preparations of isolated, purified and cultured rat liver sinusoidal endothelial cells (LEC) were studied by scanning electron microscopy (SEM), transmission electron microscopy (TEM) and atomic force microscopy (AFM). Examination of detergent-extracted LEC by SEM and TEM shows an integral cytoskeleton: sieve plates are delineated by a sieve plate-associated cytoskeleton ring and …

Sexual Selection, Physical Attractiveness, And Facial Neoteny: Cross-Cultural Evidence And Implications [And Comments And Reply], Doug Jones, C. Loring Brace, William Jankowiak, Kevin N. Laland, Lisa E. Musselman, Judith H. Langlois, Lori A. Roggman, Daniel Pérusse, Barbara Schweder, Donald Symons

Human Development and Family Studies Faculty Publications

Physical attractiveness and its relation to the theory of sexual selection deserve renewed attention from cultural and biological anthropologists. This paper focuses on an anomaly associated with physical attractiveness-in our species, in contrast to many others, males seem to be more concerned than females with the attractiveness of potential sexual partners, perhaps because humans show far more age-related variance in female than in male fecundity. The resulting selection for male attraction to markers of female youth may lead incidentally to attraction to females displaying age-related cues in an exaggerated form. This paper reports cross-cultural evidence that males in five populations …

Transitions Between Convective Patterns In Chemical Fronts, Y. Wu, D. A. Vasquez, Boyd F. Edwards, J. W. Wilder

All Physics Faculty Publications

We present a theory for the transition from nonaxisymmetric to axisymmetric convection in iodate-arsenous acid reaction fronts propagating in a vertical slab. The transition takes place away from the onset of convection, where a convectionless flat front becomes unstable to a nonaxisymmetric convective front. The transition is studied by numerically solving a reaction-diffusion equation coupled with nonlinear hydrodynamics in a two-dimensional slab.

Immunogold Labeling For The Diagnosis Of Leukemia By Transmission And Scanning Electron Microscopy, Etienne De Harven, Davide Soligo, Hilary Christensen

Scanning Microscopy

For the cell type diagnosis of leukemia in adult patients, particularly when the sampling of bone marrow is difficult, the study of peripheral blood leukocytes (PBLs) by immuno-electron microscopy provides significant information, as illustrated here in two cases of hairy cell leukemia and seven cases tentatively identified as megakaryoblastic leukemia (M7). Indirect immunogold labeling with the B-ly7 monoclonal antibody (CD103) proved valuable in confirming the diagnosis of hairy cell leukemia. Immunogold labeling for the GplIIa platelet glycoprotein (CD61) was used in cases where the light microscopy of blood films revealed possible megakaryoblastic leukemia. Under the electron microscope, however, the CD61 …

The Professional Evolution Of Wildlife Damage Management, James E. Miller

Wildlife Damage Management Conference

The term -- wildlife damage management, in lieu of animal damage control, vertebrate pest control, or nuisance animal control -- has become the currently recognized term for an area of wildlife management that a growing number of professionals spend a significant part of their time and/or career working in. The acceptance of this terminology is, however, a part of the continuing evolution of the profession and not simply a name change for political correctness. Admittedly, my purpose is not to validate or beg acceptance of this terminology. Rather, what I hope to do is to justify the underlying premise of …

From Deer Problem To People Solution: A Case Study From Montgomery County, Maryland, Jonathan S. Kays, Douglas Tregoning

Wildlife Damage Management Conference

Montgomery County, Maryland, a 495 square-mile area adjacent to Washington, D.C., is a rapidly developing, highly educated suburban community with one of the highest per capita incomes in the nation. There is increasing concern for the growth and impact of white-tailed deer (Odocoileus virginianus) populations by agricultural interests, resource professionals and residential landowners. The Montgomery County Council assembled a task force of stakeholders to examine relevant information and propose deer management options. The task force report provided detailed information on the county deer situation, 11 management alternatives, and 9 final recommendations. The county parks administrator appointed a staff …

Ecosystem Management And Wildlife Management: Compatible Or Conflicting?, David C. Guynn Jr., Greg K. Yarrow

Wildlife Damage Management Conference

Examples of wildlife-human conflicts include deer-automobile collisions, disease transmission concerns, and damage to various commodities (e.g. agricultural crops, timber production). The extent of these problems is increasing at a time when American's attitudes are shifting emphasis from commodity production to concern for the environment. Ecosystem management has been proposed as a strategy to balance concerns for commodity production and the environment. Ecosystem management, unlike traditional natural resource management, will require management over large areas for long periods of time. This new philosophy of land management requires that the natural resource base be viewed in its entirety, and not as separate …

Black Bear Damage Management In Washington State, Georg J. Ziegltrum, Dale L. Nolte

Wildlife Damage Management Conference

Black bears (Ursus americanus) foraging on trees can be extremely detrimental to the health and economic value of a timber stand. A supplemental feeding program to reduce bear damage is coordinated by the Washington Forest Protection Association's Animal Damage Control Program (ADCP). A brief overview of the ADCP is provided along with a description of bear damage and the supplemental feeding program. Success of the feeding program is demonstrated by an increasing participation and its general acceptance by the public. Timber producers placed over 400 thousand pounds of pellets in 700 feeding stations this past year.

A Strategy For Integrating Principles And Concepts Of Wildlife Damage Control Into The School Curriculum, Thomas A. Eddy

Wildlife Damage Management Conference

This paper reports an approach to educating today's youth concerning the importance of regulating numbers of wildlife species that threaten property, products and health. The emphases are on preparing teachers to integrate principles and concepts into the existing curricular materials, justifying control measures with ecological understandings and economic information and dealing effectively with sensitive animal rights issues. Opportunities for integration of specific wildlife damage control topics are suggested for lessons in the life sciences, social sciences, health, language arts and mathematics. Examples of conflict between groups of different opinions about the seriousness of a pest's activities or appropriateness of control …

Endangered Species And Irrigated Agriculture, Water Resource Competition In Western River Systems, United States Department Of Agriculture, Economic Research Service

Agriculture

This report characterizes several aspects of water allocation tradeoffs between fish species listed under the Federal Endangered Species Act and agriculture in the American West. The geographic intersection between endangered/threatened (E/T) fish and agricultural production reliant on surface water for irrigation is identified. Three findings are: (1) 235 counties, representing 22 percent of the West's counties, contain irrigated production that relies on water from rivers with E/T fish, (2) areas generating the highest revenues per acre from crop production are those most dependent on surface water irrigation, and (3) these same areas are also most likely to be drawing water …

Dietary Oxalate And Its Intestinal Absorption, Ross P. Holmes, Harold O. Goodman, Dean G. Assimos

Scanning Microscopy

Dietary oxalate is currently believed to make only a minor contribution (< 20%) to urinary oxalate excretion. A recent prospective study of stone disease suggested that dietary oxalate may be a significant risk factor. This observation led us to re-evaluate the contribution of dietary oxalate to urinary oxalate excretion. Previous studies have been hampered by inaccurate food composition tables for oxalate and inadequate methods for studying intestinal oxalate absorption. This evidence as well as factors that modify oxalate absorption are reviewed. New approaches to measure food oxalate and intestinal oxalate absorption have been examined. Capillary electrophoresis appears to be well suited for the analysis of the oxalate content of food. Two individuals consumed an oxalate-free formula diet for 7 days. This diet decreased urinary oxalate excretion by an average of 67% (18.6 mg per 24 hours) compared to oxalate excretion on self-selected diets. The absence of detectable oxalate in feces by day 6 of the diet suggested that the intestinal absorption was minimal. However, an effect of the formula diet on endogenous oxalate synthesis cannot be excluded. Restoring oxalate to the formula diet increased urinary oxalate excretion and illustrates that this experimental protocol may be well-suited for studying oxalate absorption and factors that modify it. Our results suggest that the intestinal absorption of dietary oxalate makes a substantial contribution to urinary oxalate excretion and that this absorption can be modified by decreasing oxalate intake or increasing the intakes of calcium, magnesium, and fiber.

Surviving Turbulent Organizational Environments: A Case Study Examination Of A Lumber Company's Internal And External Influence Attempts, John S. Seiter

Languages, Philosophy, and Communication Studies Faculty Publications

As a result of recent environmentalist attacks, environmental legislation, and a weakening economy, Southern California's Ganahl Lumber Company faces a situation which threatens its image, resources, financial viability, and survival. Using qualitative data gathering techniques (i.e., employee interviews and examinations of organizational documents), this study examines the ways in which Ganahl Lumber has responded to these concerns. Specifically, this study identifies whom Ganahl Lumber employees perceive to be their most important audiences and focuses on the different communication strategies that the com pany is using to influence these audiences. Conclusions indicate that, although the company is attempting to alleviate the …

Spectrometric And Imaging Measurements Of A Spectacular Gravity Wave Event Observed During The Aloha-93 Campaign, Michael J. Taylor, D. N. Turnbull, R. P. Lowe

All Physics Faculty Publications

During the ALOHA‐93 campaign coincident imaging and interferometric measurements of the near infrared and visible wavelength nightglow emissions were made from Haleakala Crater, Maui. On 10 October, 1993 a most unusual wave event was observed. This disturbance appeared as a sharp “front” followed by several conspicuous wave crests which progressed rapidly through the imager's field of view (180°). As the front passed overhead the interferometer detected a sudden jump in both the OH intensity (>50%) and its rotational temperature (∼20 K) with the temperature increase leading the intensity by almost 15 min. At the same time the imager registered …

In Situ Hybridization And Monoclonal Antibody Analysis Of Plasma Membrane Ca-Pump Mrna And Protein In Submandibular Glands Of Rabbit, Rat And Man, J. L. Borke, A. E. Zaki, D. R. Eisenmann, S. H. Ashrafi, M. M. Sharawy, S. S. Rahman

Scanning Microscopy

The degree of supersaturation of saliva with calcium (Ca) is related to the mineral phase of enamel in erupted teeth, the incidence of caries, and the formation of calculus. The mechanisms for regulating salivary Ca concentration are therefore of relevance to dentistry. Sections of rabbit, rat and human submandibular gland (SMG) were processed for immuno-histochemistry with a specific anti-plasma membrane Ca-pump antibody, 5F10. Western blots confirm that the molecular weight of the proteins identified by our antibody (135 kDa) is consistent with an appropriate molecular weight for PMCA antigen (135-150 kDa). Tissue sections were also processed for in situ hybridization …

X-Irradiation-Induced Disorganization Of Cytoskeletal Filaments And Cell Contacts In Ht29 Cells, Z. Somosy, M. Sass, G. Bognar, J. Kovacs, G. J. Koteles

Scanning Microscopy

Organization of cytoskeleton and cell contacts were studied by immunochemistry and electron microscopy in confluent HT29 cultured cells following exposure to 0.5 and 1.0 Gy doses of X-ray. Microtubules were resistant to irradiation, whereas, the actin and intermediate filaments disrupted rapidly following the treatment and their components appeared as clumps of actin and cytokeratin aggregates in the cytoplasm as demonstrated by immunochemistry. Loss of cell contacts and decrease in the number of desmosomes was also characteristic of irradiated cells. Electron microscopy revealed intact desmosomes in control cells and abnormal desmosomes in the irradiated samples characterized by the absence of tonofilaments. …

Recent data on the AFM studies of nucleoprotein complexes of different types are reviewed in this paper. The first section describes the progress in the sample preparation methods for AFM studies of nucleic acids and nucleoprotein complexes. The second part of this paper reviews AFM data on studies of complexes of DNA with regulatory proteins. These studies include two different types of DNA distortion induced by proteins binding: local bending of DNA at sites of protein binding and formation of large loops due to protein-protein interactions between molecules bound to distant sites along the DNA molecules (DNA looping). The prospects …

The Near Spacecraft Telecommunications System, R.S. Bokulic, J.R. Jensen, T.R. Mcknight

Small Satellite Conference

The Near Earth Asteroid Rendezvous (NEAR) mission, first in NASA's Discovery series, is designed to gather scientific data about the near-Earth asteroid 433 Eros. Due to launch in February 1996, the spacecraft will rendezvous with and eventually orbit the asteroid. The telecommunications system is centered about two redundant X-band transponder systems that provide the command, telemetry, and tracking functions. Although the mission has a very tight development schedule, a significant amount of new technology has been used in the telecommunications system. Included in the design are the most recent developments in transponder hardware, an X-band solid state power amplifier (a …
