Elmendorf Afb Bash Program, Robert J. Hahn , Capt, Usaf Aug 2001

Elmendorf Afb Bash Program, Robert J. Hahn , Capt, Usaf

Bird Strike Committee-USA/Canada Joint Annual Meeting: 3rd (2001)

Elmendorf AFB, located in Anchorage, Alaska, is home to over 60 aircraft to include F-15s, C-130’s, E- 3’s, C-12s, and Army Citations. In addition, it’s a major hub for both military and contract strategic airlift enroute to the Pacific. The large airspace training areas make Alaska an ideal environment suitable for large scale flying exercises. The result is several different types of aircraft from military sister services and foreign countries based out of Elmendorf throughout the year. Overlay the tremendous volume of air traffic on the huge numbers of birds in a confined area and your bound to have collision …

The Need For A Radar-Based, Operational Bird Warning System For Civil Aviation, Hans Blokpoel, B. Mackinnon Aug 2001

The Need For A Radar-Based, Operational Bird Warning System For Civil Aviation, Hans Blokpoel, B. Mackinnon

Bird Strike Committee-USA/Canada Joint Annual Meeting: 3rd (2001)

Serious multi-engine strikes on civil aviation aircraft continue to occur despite bird control efforts at and around airports. Radar-based bird warning systems currently used in military aviation are largely unsuitable for operational use in civil aviation because of the considerable constraints and inflexibility inherent in civil aviation operations. Pilots of civil aviation aircraft need to get timely, pertinent information on bird hazards, complete with options on how to minimize the associated risk. Recent advances in the design of radars and computers allow for the development of a real-time radar-based system to detect and warn of high-risk situations involving birds. High-risk …

Avian Foraging Behaviors And Habitat Manipulation At Portland International Airport, Janina M. Lamb Aug 2001

Avian Foraging Behaviors And Habitat Manipulation At Portland International Airport, Janina M. Lamb

Bird Strike Committee-USA/Canada Joint Annual Meeting: 3rd (2001)

Between January 1996 and May 2001 more than 300 bird strikes occurred at Portland International Airport. Records indicate that herons and raptors consistently make up nearly one-half of species struck. These species regularly use the airport grassland as a foraging ground, feeding on ground-dwelling rodents, including the graytailed vole (Microtus canicaudus) and vagrant shrew (Sorex vagrans). As part of a current study, various manipulations are being made to the grassland habitat and an assessment will be conducted of their effects on the airfield rodent and avian predator populations. This study will specifically correlate the presence and behaviors of predatory birds …

An Analysis Of Deer Strikes With Civil Aircraft, Usa, 1982-2000, Sandra E. Wright Aug 2001

An Analysis Of Deer Strikes With Civil Aircraft, Usa, 1982-2000, Sandra E. Wright

Bird Strike Committee-USA/Canada Joint Annual Meeting: 3rd (2001)

Wright et al. (1988) stated that although deer strikes comprise only about 2% of total reported wildlife strikes, 86% of those strikes damaged the aircraft. Dolbeer et al. (2000) ranked deer as the most hazardous species to aircraft based on damage and effect-on-flight. On January 14, 2001, a Learjet collided with two white-tailed deer (Odocoileus virginianus) on an airport in Troy, Alabama. Both pilots were critically injured and would have perished in the fire that destroyed the aircraft if rescuers had not arrived quickly. The above example of a damaging wildlife strike to an aircraft is not uncommon. Wildlife strikes …

Enhancements To The United States Bird Avoidance Model (Us Bam), Timothy Beermann, Matthew Bobo, Russell P. Defusco Aug 2001

Enhancements To The United States Bird Avoidance Model (Us Bam), Timothy Beermann, Matthew Bobo, Russell P. Defusco

Bird Strike Committee-USA/Canada Joint Annual Meeting: 3rd (2001)

The United States Bird Avoidance Model (US BAM) uses Geographic Information System (GIS) technology to analyze and correlate bird habitat, migration, and breeding characteristics with key environmental and human-made geospatial features. The application consists of raster grids covering the conterminous United States. The value for each grid pixel location is equivalent to the sum of the mean bird mass (in ounces) for all species present during one of four daily time periods (dawn, day, dusk, and night), for one of 26 two-week periods in a year. The US BAM is a desktop application that has an intuitive design and includes …

A Review Of Deer Control Devices Intended For Use On Airports, Thomas W. Seamans Aug 2001

A Review Of Deer Control Devices Intended For Use On Airports, Thomas W. Seamans

Bird Strike Committee-USA/Canada Joint Annual Meeting: 3rd (2001)

Deer living on airport habitats pose a direct threat to aircraft operations and to public safety. From 1990– 2000, about 520 collisions between civil aircraft and deer were reported in the USA with damage occurring in 86% of the collisions. Removal of individual deer by lethal or non-lethal means can reduce the potential for deer-aircraft collisions; however, such action is often controversial. Various items are marketed to keep deer away from airports, crops or residential areas. Some items have been tested while others have unsubstantiated claims of efficacy. This paper reviews the use of various fence designs, propane cannons, cattle …

An Examination Of Southeastern U. S. Satyrium (Lycaenidae: Theclinae), Part Two: The Identification And Delimitation Of Nominate Satyrium Liparops And The Description Of A New Subspecies From West Central Peninsular Florida, Ronald R. Gatrelle Aug 2001

An Examination Of Southeastern U. S. Satyrium (Lycaenidae: Theclinae), Part Two: The Identification And Delimitation Of Nominate Satyrium Liparops And The Description Of A New Subspecies From West Central Peninsular Florida, Ronald R. Gatrelle

The Taxonomic Report of the International Lepidoptera Survey

The name Satyrium liparops liparops has traditionally been applied to all liparops populations from eastern Georgia southward. This tradition is shown to be in error. The type locality of nominate liparops is restricted by original description to Screven County, Georgia. A neotype is designated from Screven County and deposited in the Museum of the Hemispheres (MOTH) collection Goose Creek, South Carolina. The range of nominate liparops is projected to be from coastal South Carolina across the far southern United States (including the Florida panhandle) and into Texas. The population in west central peninsular Florida is described as new subspecies S …

Selenium Metabolism In Drosophila, F. Javier Martin-Romero, Gregory V. Kryukov, Alexei V. Lobanov, Bradley A. Carlson, Byeong Jae Lee, Vadim N. Gladyshev, Dolph L. Hatfield

Vadim Gladyshev Publications

Selenocysteine is a rare amino acid in protein that is encoded by UGA with the requirement of a downstream mRNA stem-loop structure, the selenocysteine insertion sequence element. To detect selenoproteins in Drosophila, the entire genome was analyzed with a novel program that searches for selenocysteine insertion sequence elements, followed by selenoprotein gene signature analyses. This computational screen and subsequent metabolic labeling with 75Se and characterization of selenoprotein mRNA expression resulted in identification of three selenoproteins: selenophosphate synthetase 2 and novel G-rich and BthD selenoproteins that had no homology to known proteins. To assess a biological role for these …

Identification And Characterization Of A New Mammalian Glutaredoxin (Thioltransferase), Grx2, Vadim N. Gladyshev, Aimin Liu, Sergey V. Novoselov, Konstantin Krysan, Qi-An Sun, Valentin M. Kryukov, Gregory V. Kryukov, Marjorie F. Lou

Vadim Gladyshev Publications

A thiol/disulfide oxidoreductase component of the GSH system, glutaredoxin (Grx), is involved in the reduction of GSH-based mixed disulfides and participates in a variety of cellular redox pathways. A single cytosolic Grx (Grx1) was previously described in mammals. We now report identification and characterization of a second mammalian Grx, designated Grx2. Grx2 exhibited 36% identity with Grx1 and had a disulfide active center containing the Cys-Ser-Tyr-Cys motif. Grx2 was encoded in the genomes of mammals and birds and expressed in a variety of cell types. The gene for human Grx2 consisted of four exons and three introns, spanned 10 kilobase …

Experimental Diatom Dissolution And The Quantification Of Microfossil Preservation In Sediments, D. B. Ryves, S. Juggins, Sherilyn C. Fritz, R. W. Battarbee Aug 2001

Experimental Diatom Dissolution And The Quantification Of Microfossil Preservation In Sediments, D. B. Ryves, S. Juggins, Sherilyn C. Fritz, R. W. Battarbee

Department of Earth and Atmospheric Sciences: Faculty Publications

Four laboratory experiments on fresh, modern diatoms collected from lakes in the Northern Great Plains of North America were carried out to assess the effects of dissolution on diatom abundance and composition. Marked differences in mean dissolution susceptibility exist between species, despite sometimes significant intra- specific variation between heterovalves. Twenty-four taxa were ranked according to susceptibility to dissolution using an exponential decay model of valve abundance. This dissolution ranking was used to derive two weighted indices of sample preservation. A third index (F) was based on a simple binary classification of valve morphology into dissolved and pristine categories, …

“Becoming A Family”: Developmental Processes Represented In Blended Family Discourse, Dawn O. Braithwaite, Loreen N. Olson, Tamara D. Golish, Charles Soukup, Paul Turman Aug 2001

“Becoming A Family”: Developmental Processes Represented In Blended Family Discourse, Dawn O. Braithwaite, Loreen N. Olson, Tamara D. Golish, Charles Soukup, Paul Turman

Department of Communication Studies: Faculty Publications

We adopted a process-focus in order to gain a deeper understanding of how (step) blended family members experiencing different developmental pathways discursively represented their processes of becoming a family. Using a qualitative/interpretive method, we analyzed 980 pages of interview transcripts with stepparents and stepchildren. We studied the first four years of family development, using the five developmental pathways developed by Baxter, Braithwaite, and Nicholson (1999). Three salient issues identified in the family experiences were boundary management, solidarity, and adaptation. While the negotiation of these issues varied across the five trajectories, there were commonalities across family experiences that helped determine whether …

Modeling Vegetative Buffer Performance Considering Topographic Data Accuracy, Jason M. Brothers, Dean E. Eisenhauer, Matthew J. Helmers, Mike Dosskey, Thomas G. Franti Jul 2001

Modeling Vegetative Buffer Performance Considering Topographic Data Accuracy, Jason M. Brothers, Dean E. Eisenhauer, Matthew J. Helmers, Mike Dosskey, Thomas G. Franti

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Riparian buffers are a promising tool in efforts to reduce sediment contribution to streams. Models that predict the capacity of buffers to trap sediment have recently been developed. A number of parameters that are required to conduct such modeling efforts are derived from the topography of the site. In this study, three topographic data sources were used to generate the model input for an agricultural field with a riparian buffer. The runoff and sediment transport in the system was then simulated for three years. As a result, the area that contributed runoff and sediment to the buffer was substantially different …

Responses Of An Arctic Landscape To Lateglacial And Early Holocene Climatic Changes: The Importance Of Moisture, Daniel H. Mann, Dorothy M. Peteet, Richard E. Reanier, Michael L. Kunz Jul 2001

Responses Of An Arctic Landscape To Lateglacial And Early Holocene Climatic Changes: The Importance Of Moisture, Daniel H. Mann, Dorothy M. Peteet, Richard E. Reanier, Michael L. Kunz

United States National Aeronautics and Space Administration: Publications

Many of the physical and biological processes that characterize arctic ecosystems are unique to high latitudes, and their sensitivities to climate change are poorly understood. Stratigraphic records of land–surface processes and vegetation change in the Arctic Foothills of northern Alaska reveal how tundra landscapes responded to climatic changes between 13,000 and 8000 14Cyr BP. Peat deposition began and shrub vegetation became widespread ca. 12,500 14Cyr BP, probably in response to the advent of warmer and wetter climate. Increased slope erosion caused rapid alluviation in valleys, and Populus trees spread northward along braided floodplains before 11,000 14Cyr BP. …

The Effect Of Ethanol And Acetate On Protein Expression In Pichia Pastoris, Mehmet İnan, Michael M. Meagher Jul 2001

The Effect Of Ethanol And Acetate On Protein Expression In Pichia Pastoris, Mehmet İnan, Michael M. Meagher

Papers in Biochemical Engineering

Pichia pastoris is an excellent host for high-level heterologous gene expression, but there is still much interest in improving the productivity of recombinant protein production. P. pastoris produces a small amount of ethanol as a by-product during the glycerol fed-batch phase and the mixed-feed induction phase (glycerol-methanol) of high cell density fermentations, regardless of the phenotype (Mutf, Mut" or Mut-). We have investigated ethanol repression of the AOXl promoter using strains, GS115 (Mutf) and MC100-3 (Mut-), expressing an AOXI-lac2 fusion. The addition of 10 mg t1 ethanol at the start of methanol induction delayed P-galactosidase production and methanol utilization …

United States Fish and Wildlife Service: Publications

In the traditional survey area (strata 1-18, 20-50, and 75-77), total duck abundance was 36.1 ± 0.6 [SE] million birds. This was 14% below (P< 0.001) last year’s estimate of 41.8 ± 0.7 million birds, but still 9% above the long-term (1955-2000) average (P < 0.001). Mallard (Anas platyrhynchos) abundance was 7.9 ± 0.2 million, which is 17% below (P<0.001) the 2000 estimate of 9.5 ± 0.3 million and similar to the long-term average (P=0.08). Blue-winged teal (Anas discors) abundance was 5.8 ± 0.3 million, which was 23% below last year’s estimate of 7.4 ± 0.4 million (P=0.001), but 29% above the long-term average (P = 0.001). Green-winged teal (Anas crecca) abundance was 2.5 ± 0.2 million, 39% above the long-term average (P …

Structural And Functional Imaging With Carbon Nanotube Afm Probes, J. H. Hafner, Chin Li Cheung, A. T. Woolley, C. M. Lieber

Barry Chin Li Cheung Publications

Atomic force microscopy (AFM) has great potential as a tool for structural biology, a field in which there is increasing demand to characterize larger and more complex biomolecular systems. However, the poorly characterized silicon and silicon nitride probe tips currently employed in AFM limit its biological applications. Carbon nanotubes represent ideal AFM tip materials due to their small diameter, high aspect ratio, large Young’s modulus, mechanical robustness, well-defined structure, and unique chemical properties. Nanotube probes were first fabricated by manual assembly, but more recent methods based on chemical vapor deposition provide higher resolution probes and are geared towards mass production, …

United States Geological Survey: Publications

The High Plains aquifer underlies 174,000 square miles in parts of eight States and includes eight primary hydrogeologic units, including the well-known Ogallala Formation. The High Plains aquifer is an important resource, providing water for 27 percent of the Nation’s irrigated agricul¬tural lands in an otherwise dry landscape. Since the 1980’s there has been concern over the sustainability of the aquifer due to water-level declines caused by substantial pumping. Water quality of the aquifer is a more recent concern. As part of the U.S. Geological Survey’s National Water-Quality Assessment Program, historical water-quality data have been gathered for the High Plains …

Performance Of A Grid-Connected Photovoltaic System Using Actual And Kriged Hourly Solar Radiation, G. G. Merino, David Jones, Laverne E. Stetson

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

In this article the performance of a grid-connected PV system supplying a farmstead was evaluated using a commercially available energy balance simulation model, Hybrid2. By performing annual hourly simulations, the influence of system size, actual radiation data, and estimated radiation data on economic and energy production were assessed. The estimated radiation data were developed from kriging actual radiation data from 16 weather stations in western Nebraska. The results indicated that the capital costs associated with a PV system dictate the economic performance of the overall system. The energy costs associated with the grid-connected PV system were six times the retail …

Cyp83b1 Is The Oxime-Metabolizing Enzyme In The Glucosinolate Pathway In Arabidopsis, Carsten Horslev Hansen, Liangcheng Du, Peter Naur, Carl Erik Olsen, Kristian B. Axelsen, Alastair J. Hick, John A. Pickett, Barbara Ann Halkier Jul 2001

Cyp83b1 Is The Oxime-Metabolizing Enzyme In The Glucosinolate Pathway In Arabidopsis, Carsten Horslev Hansen, Liangcheng Du, Peter Naur, Carl Erik Olsen, Kristian B. Axelsen, Alastair J. Hick, John A. Pickett, Barbara Ann Halkier

Liangcheng Du Publications

CYP83B1 from Arabidopsis thaliana has been identified as the oxime-metabolizing enzyme in the biosynthetic pathway of glucosinolates. Biosynthetically active microsomes isolated from Sinapis alba converted p-hydroxyphenylacetaldoxime and cysteine into S-alkylated p-hydroxyphenylacetothiohydroximate, S-(p-hydroxyphenylacetohydroximoyl)-L-cysteine, the next proposed intermediate in the glucosinolate pathway. The production was shown to be dependent on a cytochrome P450 monooxygenase. We searched the genome of A. thaliana for homologues of CYP71E1 (P450ox), the only known oxime-metabolizing enzyme in the biosynthetic pathway of the evolutionarily related cyanogenic glucosides. By a combined use of bioinformatics, published expression data, and knock-out phenotypes, we identified the …

Mononuclear Phagocyte Differentiation, Activation, And Viral Infection Regulate Matrix Metalloproteinase Expression: Implications For Human Immunodeficiency Virus Type 1-Associated Dementia, Anuja Ghorpade, Raisa Persidskaia, Radhika Suryadevara, Myhanh Che, Xiao Juan Liu, Yuri Persidsky, Howard Gendelman

Nebraska Center for Virology: Faculty Publications

The pathogenesis of human immunodeficiency virus type 1 (HIV-1)-associated dementia (HAD) is mediated mainly by mononuclear phagocyte (MP) secretory products and their interactions with neural cells. Viral infection and MP immune activation may affect leukocyte entry into the brain. One factor that influences central nervous system (CNS) monocyte migration is matrix metalloproteinases (MMPs). In the CNS, MMPs are synthesized by resident glial cells and affect the integrity of the neuropil extracellular matrix (ECM). To ascertain how MMPs influence HAD pathogenesis, we studied their secretion following MP differentiation, viral infection, and cellular activation. HIV-1-infected and/or immune-activated monocyte-derived macrophages (MDM) and human …

Serotonin Transporter Promoter Polymorphism Genotype Is Associated With Behavioral Disinhibition And Negative Affect In Children Of Alcoholics, Geoffrey R. Twitchell, Gregory L. Hanna, Edwin H. Cook, Scott F. Stoltenberg, Hiram E. Fitzgerald, Robert A. Zucker

Department of Psychology: Faculty Publications

Background: Serotonergic (5-HT) dysfunction has been implicated in the etiology of both behavioral disinhibition (BD) and negative affect (NA). This work extends our previous finding of relationships between whole blood 5-HT and both BD and NA in pubescent, but not prepubescent, children of alcoholics and continues examination of a hypothesized role of 5-HT dysfunction in alcoholism risk. The long and short (L and S) variants of the 5-HT transporter gene-linked polymorphic region (5-HTTLPR) are responsible for differing transcriptional efficiencies in 5-HT uptake. Although associations have been found between the SS 5-HTTLPR genotype and severe alcoholism and neuroticism, recent reports describe …

Surgical Sterilization As A Method Of Reducing Coyote Predation On Domestic Sheep, Cassity Bromley, Eric M. Gese Jul 2001

Surgical Sterilization As A Method Of Reducing Coyote Predation On Domestic Sheep, Cassity Bromley, Eric M. Gese

United States Department of Agriculture Wildlife Services: Staff Publications

Predation by coyotes (Canis latrans) on domestic sheep is a problem for many livestock producers throughout the United States Intermountain West. We examined whether surgical sterilization of coyote packs would modify their predatory behavior and reduce predation rates on domestic sheep as compared to coyote packs with pups. From June 1997 to December 1997, we gathered baseline information on coyote pack size and movements. In winter 1998, we surgically sterilized and radio-collared members of 5 coyote packs. We also captured and radio-collared members of 6 packs that remained intact (i.e., reproductive). During summer 1998, only 1 sterile pack …
