Airport Bird Threat In North America From Large Flocking Birds (Geese) (As Viewed By An Engine Manufacturer)--Part 1, Thomas Alge

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

In worldwide aviation operations, bird collisions with aircraft and ingestions into engine inlets present safety hazards and financial loss through equipment damage, loss of service and disruption to operations. The problem is encountered by all types of aircraft, both military and commercial. Modern aircraft engines have achieved a high level of reliability while manufacturers and users continually strive to further improve the safety record. A major safety concern today includes common-cause events which involve significant power loss on more than one engine. These are externally-inflicted occurrences, with the most frequent being encounters with flocks of birds. Most frequently these encounters …

A Calibration Procedure Using Topmodel To Determine Suitability For Evaluating Potential Climate Change Effects On Water Yield, Brian Dietterick, James A. Lynch, Edward S. Corbett

Natural Resources Management and Environmental Sciences

An evaluation was conducted on three forested upland watersheds in the northeastern U.S. to test the suitability of TOPMODEL for predicting water yield over a wide range of climatic scenarios. The analysis provides insight of the usefulness of TOPMODEL as a predictive tool for future assessments of potential long-term changes in water yield as a result of changes in global climate. The evaluation was conducted by developing a calibration procedure to simulate a range of climatic extremes using historical temperature, precipitation, and streamfiow records for years having wet, average, and dry precipitation amounts from the Leading Ridge (Pennsylvania), Fernow (West …

Pretty Tree Bench Vegetation Project, Draft Environmental Impact Statement, Usda Forest Service

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

This Draft Environmental Impact Statement documents the analysis of the No Action, Proposed Action, and three action alternatives developed for the Pretty Tree Bench Project area. The Proposed Action and action alternatives considered in detail, are consistent with current management direction. Each alternative responds differently to the issues associated with the Proposed Action.

The Proposed Action prescribes disturbances within a number of different vegetation types throughout the project area. One disturbance practice uses prescribed fire. The acres of treatment by vegetation type through the use of prescribed fire are: Sagebrush (200-250 acres), Gambel Oak (450-500 acres), Pinyon/Juniper (3000-3500 acres), Ponderosa …

Race, Ethnicity And Use Of The National Park System, Dr. Myron Floyd, National Park Service, Department Of The Interior

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

This paper reviews the social science literature on racial and ethnic minority use of the National Park System. Four theoretical perspectives are examined--the marginality hypothesis, subcultural hypothesis, assimilation theory, and the discrimination hypothesis. Each perspective is described, and its strengths and limitations discussed. Research on race, ethnicity, and participation in outdoor recreation is also examined. Studies consistently show that racial and ethnic groups visit national parks and participate in recreation activities at differing rates. The style and pattern of park use also vary among racial and ethnic groups. Social science research on this topic can help park managers serve the …

Airport Bird Threat In North America From Large Flocking Birds (Geese) (As Viewed By An Engine Manufacturer)-- Part 2, Thomas Alge

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

Although the perceived threat from the growing geese population in North America has been increasing in recent years (and needs to be addressed), progress appears to have been made in reducing the damaging bird strikes through improved awareness and more effective airport bird hazard control programs worldwide. The following statistics attempt to quantify this progress for selected geographic regions. Reasons for the improvements and lessons learned, if known, are mentioned.

Airport Bird Threat In North America From Large Flocking Birds (Geese) (As Viewed By An Engine Manufacturer)--Part 3, Thomas Alge

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

This paper focuses on the increasing threat to aircraft and engines posed by the recorded growth in geese populations in North America. Service data show that goose strikes to aircraft and engines are increasing, especially in North America - consistent with the growing resident geese populations estimated by the USDA. Airport managers, along with the governmental authorities, need to develop a strategy to address this large flocking bird issue. This paper also presents statistics on the overall status of the bird threat for birds of all sizes in North America relative to other geographic regions. Overall, the data show that …

Evolution Of The Dfw International Airport Wildlife Management Program –- Lessons Learned, Curt W. Kuehner, John R. Alexander

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

On January 7, 1997, Dallas-Fort Worth International Airport experienced its first large bird strike event, involving the collision of over 350 European starlings with an American Airlines MD-80. This prompted a serious assessment of existing wildlife control procedures, and eventually resulted in the formation of the DFW Wildlife Control Program. The number of reported strikes has dropped from 157 in 1996 to 52 in 1998. The success of DFW’s program is the result of long, hard hours and extensive trial and error. However, wildlife management personnel at other airfields do not have to go through all the growing pains and …

Bird Proofing Hangars, Carl Lahser, Will Summers

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

Birds can damage flight line structures and create serious health and safety risks for workers. Many of our structures are old and not designed as bird proof. Many controllable factors are discussed but the underlying principles are to deny birds food, water and access to resting/nesting areas. Various "tools" are discussed including grounds and building maintenance, landscaping, personnel management, chemical deterrents, poisons, and shooting or trapping.

Intermediate Rings Between A Local Domain And Its Completion, William Heinzer, Christel Rotthaus, Sylvia Wiegand

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

We consider the structure of certain intermediate domains between a local Noetherian domain Rand an ideal-adic completion R* of R that arise as the intersection of R* with a field containing R. In the case where the intersection domain A can be expressed as a directed union of localized polynomial extension rings of R, the computation of A is easier. We examine conditions for this to happen. We also present examples to motivate and illustrate the concepts considered.

Golf Courses In Southern Nevada Will Significantly Impact The Water Management Efforts By Using Recycled Water Rather Than Potable Water To Irrigate Their Turf, Sean D. Ainsworth

UNLV Theses, Dissertations, Professional Papers, and Capstones

As the number of people continually move to the Las Vegas Valley and take up residence, the possibility of "running out of water" can become a reality. Having large water users (i.e. golf courses) irrigate their turf with recycled water, they will significantly impact the water management efforts in the Las Vegas Valley. When each course is irrigating their turf with recycled water, this will help ease the drinking water demand in the valley, especially during the peak demand season (summer).

Rio Natural Gas, The Alternative Fuel Of The Future, Peter Garner

UNLV Theses, Dissertations, Professional Papers, and Capstones

Automobile exhaust is a major contributor of harmful air pollutants. Exhaust emissions include water (H2O), carbon dioxide (CO2), carbon monoxide (CO), nitrous oxides (NOX), sulfur oxides (SOX), hydrocarbons (HC), and particulate matter (PM), and of these the four major air pollutants are CO, HC, NOX, and PM. Particulate matter is predominantly emitted from diesel fuel burning vehicles. In order to aid in reduction of air pollution, and reduce dependence on foreign oil imports, federal legislation has been enacted. The two prominent acts are the National Energy Security Act in 1992, which mandates use of alternative fuels, and the Clean Air …

Benthic Community Analysis Of Hog Island Bay, Virginia, David James Lewis

Biological Sciences Theses & Dissertations

The benthic infaunal macroinvertebrate communities of Hog Island Bay of the Virginia Eastern Shore were quantitatively sampled at 30 locations on August 31 and September 1, 1995. The primary objectives of this study were: (1) to characterize the subtidal macroinfaunal benthic communities of Hog Island Bay, (2) to examine relationships between abiotic factors and the macroinfaunal communities and (3) to characterize the environmental condition of the system using the Benthic Index of Biotic Integrity (B-IBI) (Weisburg et al. 1997) and the EMAP Benthic Index for the Virginian Province (Strobel et al. 1995).

The ecological condition of Hog Island Bay appears …

Characterization And Identification Of A Sludge-Associated Bacterial Isolate, Abiodun O. Adibi, Derrell Mcpherson, Minna Laine

Virginia Journal of Science

During a metal speciation study, an unusually high retention of lead ·was observed when lead solution was percolated through a column packed with sludge compost obtained from Hampton Roads Sanitation department. A bacterium was isolated from the sludge compost and identified as Bacillus sphaericus using electron microscopy, whole cell fatty acid analysis (Midi System) and Biolog GP Microplate. The isolate grows in broth and agar media containing up to 800 µM lead. Lead accumulation study using atomic absorption spectrophotometer indicates that the isolate adsorbs lead. Lead adsorption is pH dependent. The isolate contains a plasmid of approximately 40 -50 kbp …

Bulletin 4359 - Soils Of The Swan Coastal Plain, Mike Bolland

Bulletins 4000 -

Almost all the soils of the Swan coastal plain are formed by material deposited by sea, rivers and wind. The Yilgarn Block, east and south of the Scarp bordering the Swan Coastal Plain (Fig. 1), rose about 40 to 50 million years ago. This caused erosion of the block by rivers and streams, and the eroded material was either deposited onto the Swan Coastal Plain or washed into the sea. The eroded material formed new soils on the Plain.

Broadly there are two major types of soils on the Coastal Plain. The first is a series of dune system near …

Coordinated Water Resource Planning For The Sandia Basin - A Perspective Into Regional Water Planning Needs, Jeffrey L. Peterson

Water Resources Professional Project Reports

Regional water planning, a strategy adopted by the State Legislature to protect New Mexico's scant water resources from depletion and mismanagement, is evident in various water planning efforts that draw upon the cooperation of interested and vested stakeholders at the local level. Regional water-planning efforts that are currently underway can be found in the Estancia Basin, portions of the Rio Grande Basin, and the Tularosa Basin. This project utilized these water-planning efforts in order to assist in developing the basis of a regional water plan for the Sandia Basin.

The Feasibility Of Controlling The Brown Treesnake In Small Plots, Gordon H. Rodda, Thomas H. Fritts, Earl W. Campbell Iii

United States Department of Agriculture Wildlife Services: Staff Publications

There is an urgent need to provide snake-free or snake-reduced habitats for the wildlife species on Guam that have declined or disappeared as a result of predation by the Brown Treesnake, Boiga irregularis (Savidge, 1987; Fritts, 1988; Rodda and Fritts, 1992; Rodda et al., this volume, Chap. 2). At present, we know of no practical techniques for reducing or eradicating the snake throughout Guam, a densely populated island of 54,100 ha. Conserving native wildlife and reducing the incidences of snakes boarding ship and aircraft may not require the elimination of snakes from the entire island, however. Elimination of snakes from …
