The Interspecificity Of Distress Calls, A. T. Baxter, J. C. Bell, J. R. Allan, J. Fairclough

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

It is widely accepted that birds respond best to distress calls given by their own species. There is little information available however, which evaluates the effect of inter and intraspecific distress calls. During 1997 and 1998, distress calls from sub populations which are unfamiliar to local birds of the same species were assessed in Hong Kong and the U.K. Results were examined on a taxonomic basis. Response was found to be greater when con-specific calls were used. Response rates declined further as taxonomic relatedness decreased. Unlike other studies, distress calls of UK birds were effective on the same species in …

A Model To Determine The Severity Of A Birdstrike With Flocks Of Canada Geese, Richard Budgey, J. R. Allan

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

The number of birds of a flocking species likely to be ingested into an aircraft engine in a multiple birdstrike is of profound interest to engineers when they consider birdstrike tolerance in engine design. Of even more importance than the number of birds which may enter a single engine, when power can still be supplied by the remaining engines, is the probability of more than one engine suffering an ingestion. The historical birdstrike record can provide such information but is sometimes unreliable as it may be, of necessity, based upon unreliable data; the species of the birds involved may not …

The German Military Geophysical Service. Bird Migration Observation, Warning And Forecasting System: New Developments Towards An Automated Bird Migration Information System, Wilhelm Ruhe

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

The German Military Geophysical Office (GMGO) has a more than 30-years experience in all fields of bird strike prevention. Military training and flight operations usually take place in low altitudes, where also a lot of birds are present, especially near coasts and during migration periods. About one third of all the GAF bird strikes occurs during low level flight operations. The most effective tool for bird strike prevention in military low level flying is the well proved system of
· continuous actual bird migration observation (visual and by radar),
· immediate reporting,
· centralised risk evaluation,
· online warning (BIRDTAM), …

Integrated Management Systems For Australian White Ibis (Threskiornis Molucca) On The Gold Coast, Queensland, Australia, Phillip P. Shaw

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

Fueled by a large supplemental food supply at landfills in South-east Queensland, Australian White Ibis (Threskiornis molucca) populations grew from an estimated 5000 to 10000 between 1995 and 1998. Ibis counted at Coolangatta Airport reflected this growth with a 556% increase between 1989 and 1995. The multimillion-dollar loss of a Qantas airbus engine from ingestion of an Ibis, resulted in the establishment of the Ibis Management Coordination Group (IMCG). This group, comprising government, industry and community representatives, instigated an integrated program of food reduction, restriction of breeding success and public education. The program has become an example for management programs …

The Use Of Night Landfilling To Reduce Bird Hazards To Aircraft Safety, Rolph A. Davis, Joseph Mangino

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

The Atlantic County Utilities Authority (ACUA) operates a ‘bulky waste’ (non-putrescible waste) landfill at a site that is 10,300 ft from the end of the main runway at the Atlantic City (NJ) International Airport (ACY). The airport supports the Federal Aviation Administration’s Technical Center. The ACUA also operates a transfer station at its site. Municipal solid waste (msw = putrescible) is delivered to the transfer station during the day. Previously, the msw was loaded onto transfer trucks and shipped to an out-of-state landfill. In October 1997, the ACUA received a permit to conduct a 2-year experiment to dispose of the …

Bird Strike Risk Analysis On Aktion Airfield (Greece) And Recommendations For Improvements In Bird Strike Prevention, Heinrich Weitz

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

A survey of Aktion airfield in Greece was carried out from 14 to 18 October 1996 initiated by the Flight Safety Division of the NATO E-3A Component Geilenkirchen (Germany) as an reaction to the accident of an AWACS-aircraft on 14. July 1996, initially caused by a bird strike event. The survey of Aktion airfield led to the conclusion that the bird strike risk is extremely high at this airfield. Reasons are:
· The geographical location of the airfield at the Adriatic coast which is a migratory pathway for many birds.
· The location of the airfield on a narrow peninsula …

Temporal And Spatial Patterns Of Avifauna On Wetlands In The Vicinity Of Bush Field Airport, Augusta, Georgia, Usa, Robert A. Kennamer, L. Brisbin Jr., K. F. Gaines, W. L. Stephens Jr.

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

Responding to a U.S. Federal court order to improve discharged wastewater quality, Augusta, Georgia initiated development of artificial wetlands in 1997 to treat effluents. Because of the proximity to Augusta Regional Airport at Bush Field, the U.S. Federal Aviation Administration expressed concern for potential increased hazard to aircraft posed by birds attracted to these wetlands. We commenced weekly low-level aerial surveys of habitats in the area beginning January, 1998. Over a one-year period, 49 surveys identified approximately 42,000 birds representing 52 species, including protected Wood Storks and Bald Eagles, using wetlands within 8 km of the airport. More birds were …

Close-Range And Satellite Remote Sensing Of Algal Biomass In The Iowa Great Lakes, Eric A. Wilson

Department of Geography: Dissertations, Theses, and Student Research

The utility of both close-range and satellite remote sensing for assessing inland water quality was examined in the Iowa Great Lakes. The water quality of this system is of considerable interest because of its status as an environmental, recreational, and therefore, economic resource. The broad range of optical conditions present in the lakes and the wealth of literature on the system make it an ideal environment for water quality remote sensing research. The goal of this research was to survey the water quality of the Iowa Great Lakes via remote sensing, evaluate different predictive algorithms, and map the distribution of …

An Assessment Of The World-Wide Risk To Aircraft From Large Flocking Birds, J. R. Allan, J. C. Bell, V. S. Jackson

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

The difficulties encountered in interpreting the available data, which arise from incomplete or inaccurate information being submitted, or from inconsistent reporting by national organisations, illustrate the importance of recording and reporting birdstrike incidents. Even allowing for the fact that birdstrikes with large birds, and especially those with flocks, are more likely to be reported, it is probable that the database established for this project contains only a fraction of the incidents that have actually occurred. Nevertheless, some broad conclusions can be drawn from the data available, and as more data are collected, predictions and estimates can be refined and the …

The Effects Of Changes In The Northern Lapwing Population On The Bird Strike Hazard In The Uk, J. C. Bell

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

Changes in bird populations have been recognised as affecting the risk to aircraft of a bird strike. However, in terms of bird strike prevention, changes are generally only considered at the local level i.e. reducing the number of birds on the airfield. At a national level, concern has been expressed about recent increases in waterfowl, particularly geese, and the implications that this may have for flight safety, and management of the risk. However, although work is currently being undertaken to investigate if higher numbers of large waterfowl are causing an increased risk to safety (Allan, Bell & Jackson in press), …

Feather Identification And A New Electronic System For Reporting Us Air Force Bird Strikes, Carla J. Dove

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

The number of bird strike cases received from U.S. Air Force bases for identification has increased from 640 in 1996 to more than 840 in 1998. The additional workload, together with staff shortages on the BASH team, created a need for a more efficient reporting system. Previously, all bird strike remains were funneled through the Safety Center at Kirtland Air Force Base where they were logged into a database, forwarded to the Smithsonian Institution for identification, and then sent back to Kirtland for data entry of results before being returned to field personnel. This system facilitated a bottleneck in the …

Derivation Of A Dummy Bird For Analysis And Test Of Airframe Structures, Chris H. Edge, J. Degrieck

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

Certification of aircraft against the birdstrike threat is expensive and time consuming. With the need to reduce design life cycle time and costs with ever more complex structures (materials, geometries and manufacturing methods) yet with no reduction in safety, the possibilities of certification via generic analysis is an attractive proposition. This paper discusses one approach being considered within British Aerospace (BAe). It relies heavily on research activities that have derived extensive data for bird biometrics and innovative testing that can provide mechanical data for bird failure modes unique to military aircraft.

Whilst almost all birdstrike clearance is performed via testing …

Image Fusion Using Autoassociative-Heteroassociative Neural Networks, Claudia V. Kropas-Hughes

Theses and Dissertations

Images are easily recognized, classified, and segmented; in short, analyzed by humans. The human brain/nervous system; the biological computer, performs rapid and accurate image processing. In the current research the concepts of the biological neural system provide the impetus for developing a computational means of fusing image data. Accomplishing this automatic image processing requires features be extracted from each image data set, and the information content fused. Biologically inspired computational models are examined for extracting features by transformations such as Fourier, Gabor, and wavelets, and for processing and fusing the information from multiple images through evaluation of autoassociative neural networks …

Near-Field Fluorescence Microscopy Based On Two-Photon Excitation With Metal Tips, Erik J. Sánchez, Lukas Novotny, X. Sunney Xie

Physics Faculty Publications and Presentations

We present a new scheme for near-field fluorescence imaging using a metal tip illuminated with femtosecond laser pulses of proper polarization. The strongly enhanced electric field at the metal tip (ap15 nm end diameter) results in a localized excitation source for molecular fluorescence. Excitation of the sample via two-photon absorption provides good image contrast due to the quadratic intensity dependence. The spatial resolution is shown to be better than that of the conventional aperture technique. We used the technique to image fragments of photosynthetic membranes, as well as j-aggregates with spatial resolutions on the order of 20 nm.

The Role Of Iron And Reactive Oxygen Species In Particulate Air Pollution-Dependent Biochemical And Biological Activities, Kevin Richard Smith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Particulate air pollution is known to exacerbate respiratory diseases, such as asthma and chronic obstructive pulmonary disease, in humans. It has been proposed that transition meta ls from inhaled particles may play a role in this exacerbation by generating radical species leading to damage in the lungs.

The aim of this research was to determine the role that iron from particulate air pollution played in the generation of reactive oxygen species and subsequently the induction of inflammatory mediators in cells in culture. The production of reactive oxygen species by particulate air pollution was found to be dependent on the mobilization …

Evaluating Snowmelt Runoff, Infiltration, And Erosion In A Sagebrush-Steppe Ecosystem, Eric K. Duffin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Production of low-level radioactive waste (LLRW) has created a need for safe storage facilities. These facilities must be capable of isolating radioactive waste and preventing contamination from physical or biological intrusion until the waste material is isotopically stable. At the present time, managers of the Idaho National Engineering and Environmental Laboratory (INEEL) have a substantial database characterizing rainfall events and the subsequent impact on integrity of shallow land burial sites used for storage of LLRW. Little information has been gathered describing the processes of snow accumulation/ablation and the resulting impact on storage facilities. This study examines snowmelt runoff, infiltration, and …

Ultraviolet-B Radiation: Effects On Pollen Of 34 Taxa, And Inheritance Patterns And Carryover Of Radiation Response In Arabidopsis, Javad Torabinejad

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Although considerable research has addressed effects of elevated ultraviolet-B (UV-8) radiation on vegetative plant structures and processes, the reproductive biology and patterns of inheritance of UV-B tolerance have received much less attention. I examined the effects of UV-B radiation on pollen of 34 taxa. I also addressed questions concerning the patterns of inheritance of UV-B tolerance in Arabidopsis thaliana and examined potential cumulative carryover effects of UV-B exposure through multiple generations of this species.

In the first study, a significant reduction in pollen germination occurred in only five species, but pollen tube growth in more than half of the species …

Molecular Characterization Of Soil Ammonia-Oxidizing Bacteria Based On The Genes Encoding Ammonia Monooxygenase, Jose Javier Alzerreca

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Ammonia-oxidizing bacteria (AOB) are chemolithotrophs that oxidize ammonia/ammonium to nitrite in a two-step process to obtain energy for survival. AOB are difficult to isolate from the environment and iso lated strains may not represent the diversity in soil. A genetic database and molecular tools were developed based on the ammonia monooxygenase (AMO) encoding genes that can be used to assess the diversity of AOB that exist in soil and aquatic environments without the isolation of pure cultures. The amo genes have excellent potential as molecular markers; since AMO is only found in the AOB and is essential for their metabolism, …

A Social Analysis Of Grazing Management On National Forest Lands: A Case Study In Catron County, New Mexico, Alexis S. Watts

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The rural west in this country faces increased national pressure concerning the management of natural resources on public lands. Issues regarding natural resource management are becoming more important as they continue to affect rural communities and capture the attention of a variety of interest groups. Natural resource managers are increasingly required to consider social dimensions of resource use and management. Lack of consideration in these areas can lead to dissatisfied, and even hostile, local residents and interest groups. Often land managers face criticism from many groups at once as a result of management decisions.

This study analyzed a particular resource …

Biogeography Of The Short-Tailed Shrews (Blarina Brevicauda And B. Carolinensis) In The Tennessee River Valley And Adjacent Areas Of The Midsouth, Michael Jeffries

Honors Theses

In response to conflicting reports of the distribution of the two species of Blarina (B. brevicauda and B. carolinensis) in the Tennessee Valley area, specimens from The Natural History Museum of The University of Tennessee at Chattanooga and The University of Georgia were analyzed. Cranial measurements were used in both a discriminant function analysis and a principle components analysis to determine species assignments. Blarina brevicauda was found in central Tennessee, the highlands of the Cumberland Plateau, and the mountains of far east Tennessee, whereas B. carolinensis was found in the Ridge and Valley of southeast Tennessee, separated from B. brevicauda …

Growth Of Nanotubes For Probe Microscopy Tips, Jason H. Hafner, Chin Li Cheung, Charles M. Lieber

Barry Chin Li Cheung Publications

Carbon nanotubes, which have intrinsically small diameters and high aspect ratios and which buckle reversibly, make potentially ideal structures for use as tips in scanning probe microscopies, such as atomic force microscopy (AFM)^{1, 2, 3, 4}. However, the present method of mechanically attaching nanotube bundles for tip fabrication is time consuming and selects against the smallest nanotubes, limiting the quality of tips. We have developed a technique for growing individual carbon nanotube probe tips directly, with control over the orientation, by chemical vapor deposition (CVD) from the ends of silicon tips. Tips grown in this way may become …
