The paper presents a general analysis of the suitability of individual elements of the flue-gas treatment system used in SGL Carbon SA in Nowy Sacz (Poland) for the graphitization process carried out in new LWG furnaces (Castner type). The flue-gas treatment system consisted of two installations: catalytic afterburning and flue-gas desulfurization. The analysis of the suitability of various methods of flue-gas treatment was based primarily on the assessment of the effects of their application, including the reduction of concentrations of selected components in post-graphitizing gases. The work also summarizes the results of evaluation of the functioning of the whole flue-gas …


Towards Multi-Stakeholder Cooperation In Wildlife Management, Brian E. Henshaw Aug 2003

Towards Multi-Stakeholder Cooperation In Wildlife Management, Brian E. Henshaw

Bird Strike Committee-USA/Canada Joint Annual Meeting: 5th (2003)

Wildlife management at airports presents a myriad of challenges. Familiar to many in the field, is the outwitting of wily coyotes, the outsmarting of persistent birds and the outflanking of troublesome deer. Deterrents to barriers, dogs to pyrotechnics, habitat management to habitat removal, an array of increasingly effective measures can be used as part of integrated wildlife management programs to meet the challenge of increasing suburban wildlife populations and their interactions with air traffic. On or off the airfield, the objectives of all stakeholders will not be consistent with best management practices for wildlife management. This is increasingly likely outside …


Risk Analysis Of High-Speed Aircraft Departures Below 10,000 Feet, Bruce Mackinnon, Richard Sowden (Capt.), Terry Kelly Aug 2003

Risk Analysis Of High-Speed Aircraft Departures Below 10,000 Feet, Bruce Mackinnon, Richard Sowden (Capt.), Terry Kelly

Bird Strike Committee-USA/Canada Joint Annual Meeting: 5th (2003)

This paper abridges a Canadian study that examined bird-related safety risks to aircraft climbing to 10,000 feet MSL (mean sea level) at speeds in excess of 250 kias (knots indicated airspeed). The study employed a risk-based framework to examine ornithological information, bird strike data, aircraft-certification standards, aircraft climb performance and aircraft flight profiles. Foremost among its findings, the study determined that populations of high-risk bird species are increasing, that many of these species flock at the altitudes in question, and that aircraft exposure to risk will increase in part because of projected increases in aircraft movements. Examining the appropriateness of …


Fear And Loathing: The Modulatory Effect Of Stress On Memory Formation And Its Wildlife Management Implications, Arla G. Hile Aug 2003

Fear And Loathing: The Modulatory Effect Of Stress On Memory Formation And Its Wildlife Management Implications, Arla G. Hile

Bird Strike Committee-USA/Canada Joint Annual Meeting: 5th (2003)

An ongoing challenge for wildlife managers is that target species habituate to or forget about hazing, even though the animals must be somewhat stressed by the hazing. Although stress and efficient memory formation/retrieval are considered to be incompatible, research suggests that the effect of stress on memory is complex. Mild and intense stress can impair memory formation and chronic stress can disrupt memory retrieval. Intermediate stress, however, actually enhances the formation of new memories, particularly long-term memories. Unfortunately, these conclusions are based data from only a very few domesticated species under highly controlled conditions. In nature the variation in baseline …

An Automated Acoustic System To Monitor And Classify Birds, C. Kwan, K. Ho, G. Mei, Y. Li, Z. Ren, R. Xu, G. Zhao, M. Stevenson, V. Stanford, C. Rochet

Bird Strike Committee-USA/Canada Joint Annual Meeting: 5th (2003)

Collisions between aircraft and birds have become an increasing concern for human health and safety. More than four hundred people and over four hundred aircraft have been lost globally in recent years, according to a FAA report. To minimize the number of birdstikes, microphone arrays have been used to monitor birds near the airport or some critical locations in the airspace. However, the range of existing arrays is only limited to a few hundred meters. Moreover, the identification performance in low signal-to-noise environment is not satisfactory. Under the support of the US Air Force, Intelligent Automation, Incorporated (IAI) and the …

Bird Strike Committee-USA/Canada Joint Annual Meeting: 5th (2003)

As part of a continuing FAA research program in wildlife hazard assessment and management at airports, a GIS Technical Element – DFW was developed for the Wildlife Hazard Advisory System (WHAS). For the DFW GIS data layers were obtained from public sources and supplemented with airport specific information. Data themes were developed to support general analysis of wildlife habitat on the AOA and adjacent airport property, and analysis was extended to a distance of 25 miles from the airport to accommodate all aircraft in high risk airspace. Over 10,000 wildlife report records were integrated with data on birdstrikes and runway …


The Relationship Of Military Aircraft Activity To Raptors In Central Labrador, Dawn K. Laing, David M. Bird, Tony E. Chubbs, Maj. Gary Humphries Aug 2003

The Relationship Of Military Aircraft Activity To Raptors In Central Labrador, Dawn K. Laing, David M. Bird, Tony E. Chubbs, Maj. Gary Humphries

Bird Strike Committee-USA/Canada Joint Annual Meeting: 5th (2003)

Central Labrador is a notable breeding area for Osprey (Pandion haliaetus) and Bald Eagles (Haliaetus leucocephalus). It is also the location of the North Atlantic Treaty Organization’s (NATO) Low level Training Area (LLTA) for fighter aircraft, covering an area of approximately 130,000 km2 over Labrador and north-eastern Québec. Currently, military aircraft based in Goose Bay, Labrador annually conduct 5,000-7,000 sorties and are permitted to conduct up to 18,000 per flying season (DND 1995). The interaction between the two is frequently fatal for the bird and potentially so for the aircraft and pilot. Since the early 1990s, the Department of National …

A Model For Assessing Bird Strike Risk At Proposed New Airports, Jenny Bell, Niall H. K. Burton, Richard Walls, Andy J. Musgrove, Mark M. Rehfish, John Allan, George Wattola

Bird Strike Committee-USA/Canada Joint Annual Meeting: 5th (2003)

There are many criteria which need to be assessed when carrying out site selection for new airport developments. One of those which should be assessed is prospective bird hazard and bird strike risk – unfortunately, this is rarely considered as a factor. One reason for this may be the lack of available methodology for such work. This paper presents the methodology used during a recent hazard assessment for a proposed new airport for London. The methodology builds on previously described risk assessment techniques, which were developed for operational airports. It allows an assessment of the likelihood of bird strikes to …


Through A Bird’S Eye – Exploring Avian Sensory Perception, Robert C. Beason Aug 2003

Through A Bird’S Eye – Exploring Avian Sensory Perception, Robert C. Beason

Bird Strike Committee-USA/Canada Joint Annual Meeting: 5th (2003)

For too many birds their environment includes airfields and aircraft. Knowing avian sensory abilities, researchers can design experiments and develop new devices and techniques to deter birds from aircraft on and away from airfields. How birds perceive the world about them determines many choices, including foraging, predator avoidance, and flight. Most experiments to investigate the sensory abilities of birds have been developed and analyzed using only human sensory capabilities, which often differ markedly from those of birds. My objective is to review and synthesize what is known and what is unknown about avian sensory capabilities. Compared with humans, birds can …


Risk-Based Modeling To Develop Zoning Criteria For Land-Use Near Canadian Airports, Rolph A. Davis, Terry Kelly, Richard Sowden, Bruce Mackinnon Aug 2003

Risk-Based Modeling To Develop Zoning Criteria For Land-Use Near Canadian Airports, Rolph A. Davis, Terry Kelly, Richard Sowden, Bruce Mackinnon

Bird Strike Committee-USA/Canada Joint Annual Meeting: 5th (2003)

Land development in the vicinity of airports often leads to land-use that can attract birds that are hazardous to aviation operations. For this reason, certain forms of land-use have traditionally been discouraged within prescribed distances of Canadian airports. However, this often leads to an unrealistic prohibition of land-use in the vicinity of airports located in urban settings. Furthermore, it is often unclear that the desired safety goals have been achieved. This paper describes a model that was created to assist in the development of zoning regulations for a future airport site in Canada. The framework links land-use to bird-related safety-risks …

The National Wildlife Strike Database For The Usa: 1990 To 2002 And Beyond, Sandra E. Wright, Richard A. Dolbeer

Bird Strike Committee-USA/Canada Joint Annual Meeting: 5th (2003)

The National Wildlife Strike Database for Civil Aviation in the USA became operational in 1995 with the initiation of data entry of all strikes beginning in 1990. Since 1995, approximately 46,600 reported strikes from 1990-2002 involving civil aircraft in the USA or for USA carriers in foreign countries have been entered into the database. About 97% of the reported strikes have involved birds and 3% have been with mammals or reptiles. Over 2,000 reported strikes have indicated substantial damage to the aircraft. The database has proven to be an extremely useful source of objective information on the extent and nature …


Are Birds Scared By Rotating Mirrors?, Thomas W. Seamans, Scott C. Barras, Zachary J. Patton Aug 2003

Are Birds Scared By Rotating Mirrors?, Thomas W. Seamans, Scott C. Barras, Zachary J. Patton

Bird Strike Committee-USA/Canada Joint Annual Meeting: 5th (2003)

Blackbirds (Icteridae) create human health and safety concerns when roosting in large numbers near airports or other urban areas. Therefore, there is considerable demand for effective nonlethal techniques to deter these birds. We tested the effectiveness of rotating mirrors (Peaceful Pyramid®) to keep blackbirds away from decoy traps. Mirrors were in place on traps for 5 consecutive days with control traps having similar a device in place but without mirrors. The total number of birds captured in traps with clear mirrors and control traps did not (P = 0.62) differ. When red mirrors were used, the total number of birds …

Gis And Wildlife Management Activities At Airports, Shelley Gray

Bird Strike Committee-USA/Canada Joint Annual Meeting: 5th (2003)

Wildlife observations collected over time at a US Air Force Base (AFB) have been visually displayed through Geographic Information System (GIS) technology. By continuing to expand upon the capabilities of GIS, USDA Wildlife Services has been able to manage the Seymour Johnson AFB airfield and surrounding areas in a practical manner. A Wildlife Hazard Assessment of the AFB used GIS to clearly display the location of birds and mammals observed on the airfield. Baseline themes of natural features (i.e. rivers, woodlands, etc.) were related to wildlife observations to determine areas requiring management. Additionally, GIS has been a useful tool to …

A Re-Evaluation Of The Us Epa Radon Risk Categorization For Unicoi County, Tennessee., William Grant Parsons Aug 2003

A Re-Evaluation Of The Us Epa Radon Risk Categorization For Unicoi County, Tennessee., William Grant Parsons

Electronic Theses and Dissertations

Effective risk communication is based on appropriate risk characterization. A reevaluation of the 1987 US EPA radon risk categorization of Unicoi County Tennessee was conducted using in-home radon concentrations, determined in a long-term monitoring study. Radon concentrations were measured in 69 homes using Electret Passive Environmental Radon Monitors (E-PERM’s), following standard methods. Radon concentrations determined in this study (avg. 4.03 ± 3.04) were significantly higher than those measured in the USEPA study (avg. 1.96 ± 1.08). Using this study’s data, the risk categorization was recalculated with the US EPA Radon Index Matrix Model. The model re-categorized Unicoi County from a …

Fluctuations In Chinook Salmon (Oncorhynchus Tshawytscha) Counts At Three Lower Columbia River Spawning Sites, Eric Michael Loomis May 2003

Fluctuations In Chinook Salmon (Oncorhynchus Tshawytscha) Counts At Three Lower Columbia River Spawning Sites, Eric Michael Loomis

UNLV Theses, Dissertations, Professional Papers, and Capstones

Several hypotheses were developed to explore the pronounced increase in Chinook salmon (Oncorhynchus tshawytscha) returning to spawning grounds at the Cowlitz, Kalama, and Lewis Rivers, three tributaries of the lower Columbia River. The study was conducted using data compiled over a ten-year span from 1991-2001. Preliminary indications are that trends in climate are linked to these increases, with the absence of El Niño events and fluctuations in winter precipitation as likely explanations of these phenomena. The unique nature of Chinook life cycles causes them to utilize a variety of habitats that require ideal conditions for maximum survival rates. Correlations between …
