An Investigation Of Plume Rise From Titan Iv Rocket Launches, Joseph D. Brands

Theses and Dissertations

Space launches at Cape Canaveral Air Station (CCAS) and Vandenberg Air Force Base (vAFB) produce exhaust ground clouds from the solid rocket boosters and liquid hypergolic fuels containing several toxic substances. In order to estimate the health effects that would be imposed upon the public by scheduled launches, range safety officials rely on the Rocket Exhaust Effluent Diffusion Model to predict ground level concentrations of these substances. A drawback to the REEDM is its underprediction of the initial ground clouds stabilization height. This underprediction causes an overprediction of the ground level toxic substance concentrations. This thesis focused on increasing the …

The Migration Of Arsenic And Lead In Surface Sediments At Three Kids Mine Henderson, Nevada, Douglas Brian Sims

Publications (WR)

This study focused on the distribution of arsenic and lead in surface sediments at Three Kids Mine in Henderson, Nevada. The mine site encompasses approximately 470 acres of desert and is situated above two developing communities (Lake Las Vegas and Calico Ridge) and the Las Vegas Valley's water source (Lake Mead). Transport of arsenic and lead appears to have occurred within a limited range in both the eastern and western washes on the eastern and western sides of Three Kids Mine. Concentrations of arsenic range between 20 mg/kg (ppm) and 1130 mg/kg and between 20 mg/kg and 8400 mg/kg for …

Public Participation Program Development: An Analysis Of Public Participation In The Water Industry, Marcia Lynne Holmberg

UNLV Theses, Dissertations, Professional Papers, and Capstones

The field of public participation is a distinct, but yet unpolished facet within the public relations industry. While the purpose of and need for public participation are becoming increasingly clear, many remain unaware or unconvinced of its advantages. Likewise, even among those who endorse the necessity of public participation, its methods and strategies continue to be a mystery to most.

One industry, in particular, that has recognized and embraced the benefits of conducting public participation is the water utility industry. The purpose of this thesis is to 1) crystallize the understanding of why public participation is a necessary and advantageous …

A Plan For Characterizing Waste For The Defense Special Weapons Agency At The Nevada Test Site, Tiffany A. Hatcher

UNLV Theses, Dissertations, Professional Papers, and Capstones

In 1976, Congress adopted the Resource Conservation and Recovery Act (RCRA) to govern hazardous waste. The Act was amended in 1984 with the Hazardous and Solid Waste Amendments in order to further define the requirements of RCRA. RCRA is meant to protect human health and the environment from the effects of hazardous waste, promote waste minimization, and encourage material recycling and recovery. For this purpose, regulations are implemented that cover every aspect of the hazardous waste problem, including generation, transport, treatment, storage, and disposal.

Generators of waste are the most important part of this chain. As defined in RCRA, a …

Preliminary Investigation Of The Extent And Effects Of Sediment Contamination In White Lake Near Whitehall Leather Tannery, Richard Rediske, Gary Fahnenstiel, Tom Nalepa, Peter Meier, Claire Schelske

Scientific Technical Reports

By using a combination of chemistry, toxicological evaluation, ecological analysis, and radiodating, this investigation has defined the ecological effects and the nature and extent of sediment contamination in the Tannery Bay area of eastern White Lake. The sediments in Tannery Bay represent a source of chromium transport for most of the eastern basin of White Lake. The recent deposition of chromium contaminated sediments exceeding 500 mg/kg in down gradient locations shows that export processes are responsible for the movement of this material from Tannery Bay. Arsenic and mercury appear to be less mobile and are retained in the sediments of …

The 1% treated group was received 1 % of methomyl LD₅₀, while the 10% treated group was received 10% of methomyl LD₅₀. The administration was orally and repeated three times with 24 hr intervals time. The effect of methomyl was investigated in four experimental run, by analysing the change in cell count in bone marrow after methomyl treatment. It was found that methomyl treatment caused significant reduction …

Pesticide-Related Health Problems And Illness In Farm-Workers In The United Arab Emirates, Mahra Mohammed Mahmood Beshwari

Theses

Arabian Gulf countries, witnessed rapid development in many aspects of life. Although these

developments have improved the quality of life in the UAE, they have drawbacks that generated

health problems and environmental hazards. One of the consequences of rapid development is the

usage of large amounts of pesticides in agricultural production for the sake of increasing the yield of crops. However, the expanded use of these pesticides is known to result in acute respiratory symptoms and changes in body metabolism. To-date, no population-based study has been conducted to investigate the effects of pesticides on plasma amino acids and liver enzyme …

Development Of An Integrated Canada Goose Management Program In Virginia, Martin Lowney, Phil Eggborn, Gary Costanzo, Don Patterson

Wildlife Damage Management Conference

Wildlife managers in the State of Virginia developed an integrated Canada goose (Branta canadensis) damage management program in 1996 to address increasing damage caused by resident (non-migratory) Canada geese, primarily in urban/suburban areas. The previous Canada goose damage management program relied primarily on harassment and relocation. The integrated program was made available to citizens, homeowner associations, businesses, organizations, city and county governments, and state and federal agencies in 1997. The Integrated Canada Goose Management Program was developed by U.S. Department of Agriculture-Animal and Plant Health Inspection Service-Wildlife Services, Virginia Department of Agriculture and Consumer Services, Virginia Department of …

Historical Forces Shaping Americans' Perceptions Of Wildlife And Human-Wildlife Conflicts, Michael R. Conover, Denise O. Conover

Wildlife Damage Management Conference

From colonial times until the 19th century, the dominant American view of wildlife and its management was dualistic—wildlife species were divided into good animals (those which had commercial value or could be eaten) or bad animals (those which threatened the colonists’ safety or food supply). Philosophically, early colonial Americans believed that the environment was to be manipulated for man’s purposes. Under the impact of modernization, Darwinian influence, over-exploitation of resources, and environmentally-conscious professionals, Americans in the late 19th century began to appreciate the recreational value of wildlife and to develop a more protective attitude toward it. Still the dichotomy between …

Private Nuisance Wildlife Control: Is There A Future In Kansas?, Charles Lee, Philip Gipson, Lucas Koch

Wildlife Damage Management Conference

The private industry involvement in nuisance animal damage control is increasing in Kansas. Improved oversight of that industry is needed and the Kansas Department of Wildlife and Parks (KDWP) plans to implement a mandatory education and certification program beginning in 1998. KDWP currently issues permits to individuals who wish to trap or control nuisance animals outside of normal harvest seasons. Individuals who have held these permits to conduct nuisance animal damage control were surveyed in 1995 to better understand the status and needs of that industry in Kansas. A 3-page mail survey was sent to all 93 permit holders. Raccoons …

Wildlife-Caused Losses For Catfish Producers In 1996, Alice P. Wywialowski

Wildlife Damage Management Conference

In January 1997, the National Agricultural Statistics Service (NASS) surveyed catfish producers about wildlife-caused losses in 1996, Of the 1,465 catfish producers in 15 states surveyed, 1,008 (68.8%) agreed to complete the survey. Surveys were conducted primarily by telephone, but some producers received mail surveys. The response rated varied among states. The majority of catfish producers were in Mississippi (n=-300), followed by Alabama (n=163), and then Arkansas (n=117). The remaining states each had < 100 respondents. Data were analyzed for 6 regions, each with a sample size of > 100 respondents. Overall, 69% of catfish producers cited a wildlife-caused loss of catfish. Producers cited losses to wildlife most frequently in Mississippi (81%), followed by states adjoining …

Electric Fencing Reduces Heron Predation At Northeastern Trout Hatcheries, Mark E. Tobin, James F. Glahn, Erica S. Rasmussen

Wildlife Damage Management Conference

Great blue herons (Ardea herodius) are the most common avian predator at commercial trout hatcheries in the northeastern United States. We evaluated a 2-strand electric fence for excluding this species from raceways at 2 commercial trout hatcheries in central Pennsylvania. Fences consisted of high density polyethylene 400-lb strength tape supported by fiberglass posts and energized by either a battery-powered or a solar-powered fence charger. Labor and material for constructing the fences at the 2 sites averaged $1.32/m of raceway. Bird visitation at the 2 sites initially declined, but returned to pre-installation levels. However, bird use of raceways declined …

Attempted Relocation Of A Ring-Billed Gull Roost At Washington National Airport, Jessica Dewey, Martin Lowney

Wildlife Damage Management Conference

Gulls, particularly ring-billed gulls [Larus delawarensis], have been identified as a threat to aircraft operations at Washington National Airport (now Ronald Reagan National Airport) in northern Virginia. Through bird surveys conducted in 1992, 1993, and 1997, an estimated 7,000 gulls were observed roosting during winter on the Potomac River near the airport. A harassment program was run on 5 consecutive evenings, 24-28 February 1997, to relocate the roosting gulls. Six to 8 people shot pyrotechnics from shore and 2 boats for 2 hours prior to dusk each evening. Each evening the gulls arrived consistently later than the prior …

Double-Crested Cormorant And Ring-Billed Gull Damage Management On Lake Champlain: Are Basin-Wide Objectives Achievable?, Richard Chipman, Dennis Slate, Larry Garland, David Capen

Wildlife Damage Management Conference

Ring-billed gulls (Larus delewarensis) and double-crested cormorants (Phalacrocorx auritus) have nested on Lake Champlain since 1949 and 1982, respectively. Recent increases in cormorant nesting populations and pioneering activities of both species to previously uncolonized islands have resulted in impacts related to accumulation of bird guano and interspecific competition with less common species. Of primary concern are: decreases in wildlife and plant diversity on islands; reduced aesthetics and property values of island associated with the loss of trees; and predation or competition for nesting space with other species such as the state-endangered common tern (Sterna hirundo …

Nesting Populations Of Double-Crested Cormorants, Great Blue Herons, And Great Egrets In The United States And Canada: Implications For Management, Jerrold L. Belant, Laura A. Tyson

Wildlife Damage Management Conference

Populations of piscivorous birds in North America are receiving increasing attention in the southeast United States because of depredations at aquaculture facilities. We obtained recent (most since 1994) estimates for the number of nesting double-crested cormorants (Phalacrocorax auritus), great blue herons (Ardea herodias), and great egrets (Casmerodius albus) in the United States (US) and Canada from published references and by conducting telephone interviews with state and provincial biologists. Using previously-published data, we also determined annual rates of change in the number of cormorants since about 1990. Estimates for minimum numbers of nesting pairs (minimum …

Repellency Of Methyl Anthranilate To Captive Great Egrets, Michael L. Avery, John S. Humphrey, David G. Decker

Wildlife Damage Management Conference

Because effective deterrents are hard to find, it has been suggested that methyl anthranilate (MA) be applied to the surface of fish ponds to discourage bird predation. We conducted two short-term evaluations of a formulation for this use, ReJeX-iT TP-40. First, we assessed the response of tropical fish to TP-40 applications in small wading pools. After 15 minutes, all fish virtually were motionless at or near the bottom of the pool. Fish in the control pools actively swam and most were within 3 cm of the surface of the pool. No mortality occurred, and fish activity returned to almost normal …

Controlling Great-Tailed Grackle Damage To Citrus In The Lower Rio Grande Valley, Texas, James F. Glahn, Jose D. Palacious, Melvin V. Garrison

Wildlife Damage Management Conference

Great-tailed grackle (Quiscalus mexicanus) damage to citrus is a serious concern to producers in the lower Rio Grande Valley of Texas. Damage caused by grackles pecking fruit is initiated by breeding colonies in the spring on immature fruit and extends through the fall and winter on ripening fruit. The most significant damage occurs during the post-breeding period of July through September when neither the currently registered DRC-1339-treated dog food bait nor frightening strategies are effective. Observations by Texas Wildlife Services personnel suggested that watermelon was highly attractive to grackles during the period when dog food baits are poorly …

Development Of The Virginia Cooperative Coyote Control Program To Protect Livestock, Martin Lowney, John Houben, Phil Eggborn

Wildlife Damage Management Conference

The Virginia Cooperative Coyote Control Program was created in 1990 to address increasing livestock losses to coyotes and the inability of producers to solve such problems themselves. The eastern coyote arrived in Virginia in the late 1970s or early 1980s. Lobbying efforts of agricultural groups, such as the Virginia Sheep Federation, helped create a cost-share program administered by the Virginia Department of Agriculture and Consumer Services (VDACS) and U.S. Department of Agriculture-Animal and Plant Health Inspection Service-Wildlife Services (USDA-APHIS-WS). The objective of the program was to educate producers about control methods and to alleviate damage by removing offending coyotes where …

Do You Have Your Skates On?, Gary J. San Julian

Wildlife Damage Management Conference

It is an honor to keynote this conference as we think about our profession in the next century. Jim asked me to predict what the future of wildlife damage management might look like in the year 2020. I explained to him that I have not been actively engaged in doing wildlife damage work for almost 9 years and I had been in an administrative role. Jim knew that I am going back to a faculty position in the next several months. He thought it was great for a person coming out of retirement to predict the future.

Development Of A Double-Crested Cormorant Damage Management Plan For The Southeastern United States, Keith J. Andrews, Pete Poulos, Charles Bo Sloan, Jerrold L. Belant, Paige G. Ross, Paul Debow

Wildlife Damage Management Conference

In response to needs within the aquaculture industry to alleviate increasing depredation by double-crested cormorants (Phalacrocorax auritus), the U.S. Department of Agriculture, Animal and Plant Health Inspection Service, Wildlife Services, in conjunction with Federal, State, and Canadian wildlife and fisheries agencies, the aquaculture industry, and other wildlife professionals, is developing the framework for a comprehensive cormorant damage management program that uses an integrated wildlife damage management approach. This cooperative effort will produce a meaningful, mutually beneficial program that will reduce the effects of cormorants on aquaculture and sport and commercial fisheries, improve understanding of cormorant biology, and avert …

The Press And Citizen Participation: A Content Analysis, Lisa Pelstring, James Shanahan, Ben Perry

Wildlife Damage Management Conference

We conducted a content analysis of regional New York State newspapers to assess media coverage of the Department of Environmental Conservation’s (DEC) deer management program. The goal of this analysis was to ascertain media depiction of DEC’s deer management program during the 1985-97 time period. Specifically, this research examines how deer management issues were portrayed both prior to and after implementation of a DEC public participation program (the Citizen Task Force [CTF] process) to determine if deer management issues received more favorable coverage after CTFs were implemented.

Bird Abundance At Accomack County Southern Landfill, Melfa, Virginia, In Relation To Various Management Activities, Laura Francoeur, Martin Lowney

Wildlife Damage Management Conference

Birds, especially gulls (Larus spp.), are attracted to landfills, and when landfills are close to airports, birds can pose a threat to aircraft safety. We conducted a 1-year ecological study to address concerns of the Federal Aviation Administration (FAA) and Accomack County, Virginia, officials over potential wildlife hazards caused by the Accomack County Southern Landfill. During 48 surveys conducted from December 1995 to December 1996, we observed 112,693 birds at the landfill (x̄=503). Nine species represented 97% of all observations. Bird numbers varied during the year, increasing during winter and declining during summer. Bird abundance appeared unaffected by …

The Mass Media And Stakeholders' Beliefs About Suburban Wildlife, Cynthia A. Loker, James Shanahan, Daniel J. Decker

Wildlife Damage Management Conference

This study examines how suburban audiences obtain information about 3 species in New York State (whitetail deer [Odocoileus virginianus], beaver [Castor canadensis], and Canada goose [Branta canadensis]). Respondents in 3 suburban areas were surveyed on concerns and interests about a particular species in their area. Respondents also were surveyed about preferred sources for species information and actual source use. Finally, respondents were surveyed about general media use. “Uses-and-gratifications” theory was used to characterize respondents’ information behavior for species information. Specific recommendations for communication planning are offered.

Vertebrate Damage Management: The Future Of An Evolving Profession, Robert H. Giles Jr.

Wildlife Damage Management Conference

The author argues that an objective of a new group of people taking a systems approach to large wild animal problems should be to manage damage as a cost-reducing role within a total, profitable, long-term system, not necessarily to control the "pest." The needs are for well-grounded financial analyses both for customers, the public, the resources, and the well-being of the profession. A point of view is advanced for the need for evolving pest-related operations into a new, unique profession that is involved in a profound way as an element of a cost-effective total land and human resource production system.

Cytochrome P450 And Organochlorine Contaminants In Black-Crowned Night-Herons From The Chesapeake Bay Region, Usa, Barnett A. Rattner, Mark J. Melancon, Clifford P. Rice, Walter Riley Jr., John D. Eisemann, Randy K. Hines

United States Department of Agriculture Wildlife Services: Staff Publications

Black-crowned night-heron (Nycticorax nycticorax) offspring were collected from a relatively uncontaminated coastal reference site (next to Chincoteague National Wildlife Refuge, VA, USA) and two sites in the Chesapeake Bay watershed (Baltimore Harbor, MD and Rock Creek Park, Washington, DC, USA). Hepatic microsomal activities of benzyloxyresorufin-O-dealkylase and ethoxyresorufin-O-dealkylase were significantly elevated (up to sixfold and ninefold induction, respectively) in pipping embryos from the Baltimore Harbor colony compared to the reference site, whereas values in embryos from the Rock Creek Park colony were intermediate. Concentrations of organochlorine pesticides and metabolites in pipping embryos from both sites …
