4-H And Youth Related Programs, Major L. Boddicker

Great Plains Wildlife Damage Control Workshop Proceedings

The value of a youth oriented wildlife management program is obvious. Youth is an audience with an open mind, often not committed to old errors. With a proper and intensive education program, a strong future impact can be made on the acceptance and success of animal damage control programs. Programs of quality can change a youth's outlook on problem wildlife from one of apathy or intolerance to one of positive management and high damage tolerance.

Welcome, Robert A. Bohannon

Great Plains Wildlife Damage Control Workshop Proceedings

The Workshop which was held two years ago was a success. According to registration records this year, people from all of the Great Plains states are in attendance and 92 persons are registered. We are especially pleased to welcome C.F. Barrett, Supervisor of Animal Pest Control of the Alberta Department of Agriculture who travelled the longest distance to attend.

Tree Squirrel Damage Control, Robert L. Carlton

Great Plains Wildlife Damage Control Workshop Proceedings

Unlike some wildlife species, tree squirrels are treated as game animals in every state where found. Thus, there are often restructions on times when tree squirrels may be controlled. In areas of high human population, there may be restrictions on ways in which squirrels may be controlled. Finally, because of the human affection for squirrels, there may be places where effective control is almost impossible.

Feral Mammal Damage And Control, Philip S. Gipson

Great Plains Wildlife Damage Control Workshop Proceedings

Feral populations of five domestic mammals, dogs (Canis familiaris), house cats (Felis catus), hogs (Sus scrofa), burros (Equus asinus) and horses (Equis caballus), presently occur in North America. At times these animals cause problems, damaging crops or livestock, or competing with livestock and native wildlife for food and living space. Free-living bands of a sixth species, cattle (Bos taurus), formerly occurred in the Southwest. Feral mammals are adaptable, and they have become a permanent part of the fauna in many states. Researchers generally ignored feral mammals in the past, although numerous reports have been published in the past 10 years. …

Muskrat Damage Control, James E. Miller

Great Plains Wildlife Damage Control Workshop Proceedings

Muskrat control, like any type of vertebrate pest control, is not an easy task. It requires not only practical effective methods, but a diligent effort, as well. When speaking of muskrat control, we are not implying total eradiction, because, first of all, it would not be possible, and secondly, in most areas other than agricultural croplands, they are not considered a pest.

Analysis Of The Sediment Filtering Action Of Grassed Media, Billy J. Barfield, David T. Y. Kao, E. W. Tollner

KWRRI Research Reports

The movement of sediment in non-submerged flow through a rigid grass media was studied experimentally by simulating the media with cylindrical nails. Models of sediment movement were developed from probablistic reasoning and from the use of existing parameters describing total bed material in open channel flow. In the probability analysis, the percent sediment trapped was found to be a power function of the number of potential fall paths, N_f,a particle could make from the surface to the bed while traveling through the filter media. The percent trapped was also found to be an inverse power function of the …

Tertiary Treatment Of Wastewater Using Oxidation Ponds, Robert A. Lauderdale, John R. Moeller, Raymond D. Hamilton

KWRRI Research Reports

The purpose of the project was to determine the value of using lagoons as a supplemental process for treating the effluent from an activated sludge wastewater treatment plant.

Only tentative conclusions can be suggested since the project was not carried to completion. It appears that lagoons will have only minimal effect on the amounts of total nitrogen and phosphate in the plant effluent, although conversion of a portion of the ammonia to nitrate can be expected. However, the concentration of ammonia was never lower than that required by EPA guidelines. Some reduction of soluble BOD appears to occur, perhaps through …

Rural Residential Water Demand In Kentucky: An Econometric And Simulation Analysis, Orlen C. Grunewald, C. T. Haan, David L. Debertin, D. I. Carey

KWRRI Research Reports

This study proposed that demand management through pricing policies can be used in conjunction with supply management to solve water supply problems in Kentucky. Economic principles were shown to apply to rural residential water use. From the economic model, a hyperbolic demand function was theorized. The mathematical form of this function used quantity of water as a function of price, income, value of residence, evaporation, and persons per residence. This function was estimated using ordinary least squares regression. A log-linear model was found to be a satisfactory representation of the demand function. Price was the only independent variable which was …

A Chronological Comparison Of The Vegetation Of Vigo County, Indiana Presettlement (1814) Versus Contemporary (1974), Ellen Oliver Donselman

All-Inclusive List of Electronic Theses and Dissertations

A study of the vegetation of Vigo County was undertaken to categorize and map presettlement and contemporary vegetation patterns, and to relate these patterns to climate, topography, soil types and land-use changes. Vigo County was divided into four major topographic units according to geography and soil types. Ttese units served as the basis for this study. The General Land Office Survey of 1814 provided data for the presettlement forest distribution. Sixteen contemporary stands were sampled to obtain data for characterization of present-day vegetation patterns. Standattributes tables and size-class tables were constructed for four contemporary and four presettlement forest units. A …

The Flood Disaster Protection Act Of 1973: A Rational Approach To Flood Damage Prevention, Larry J. Wilson

IUSTITIA

Throughout history, man has utilized rivers for water supply, transportation, power generation, and waste disposal. This strong relationship has encouraged the location of human settlements near rivers and streams despite the risk of periodic flooding. The modern technology of transportation and public services has reduced the necessity for riverside locations, but the development of flood plains in urban areas has continued, resulting in the periodic loss of human life and property when flooding has occurred. Within the United States, flooding has taken over 5000 lives in the last fifty years and causes an estimated $1.25 billion in property damages annually.' …

Trace Metals And Major Elements In Water-Soluble Rocks Of Northwest Arkansas, George H. Wagner, Kenneth F. Steele, Doy L. Zachry Jr.

Arkansas Water Resources Center Technical Reports

Trace metals in limestone are potential water contaminants because they can enter the ground water when the limestone is dissolved by carbonic acid and other naturally occurring acids. Four local limestones, the St. Joe and Pitkin Formations (Mississippian) and the Brentwood and Kessler Members of the Bloyd Formation (Pennsylvanian) were sampled in a five county area in Northwest Arkansas. Atomic absorption analyses were made for Na, K, Mg, Ca, Zh, Cu, Ba, Fe, Co, Cr, Ni, Mn, Li and Sr on the acid soluble material of the samples. All the limestones are relatively pure CaCO3 with Pitkin the purest, 93.4%. …

An Engineering Solution To Improve Water Quality In A Tidal Lagoon, Richard Warren Price

Civil & Environmental Engineering Theses & Dissertations

Rising demand for better water quality stimulated research and development of ways to improve the quality level in existing as well as proposed water systems. At present, most of the solutions focus on biological and chemical processes.

Many natural or man-made water bodies act as receivers for both point and non-point pollution sources. Employment of biological and chemical treatment has proved successful in many of these cases; however, in some cases a more natural physical solution of an engineering mode would be more desirable. A "flushing" technique using the tidal fluctuation as a driving force has been investigated and the …

Application Of Satellite Data And Lars' Data Processing Techniques To Mapping Vegetation Of The Dismal Swamp, Jeffrey Allan Messmore

Biological Sciences Theses & Dissertations

This study concerned the feasibility of using digital satellite imagery and automatic data processing (ADP) techniques as a means of mapping swamp forest vegetation. Multispectral scanner data acquired by the Earth Resources Technology Satellite (ERTS-1; renamed LANDSAT-1) was analyzed using ADP techniques developed by Purdue University's Laboratory for Applications of Remote Sensing (LARS). The site for this investigation was the Dismal Swamp, a 210,000 acre swamp forest located south of Suffolk, Va. on the Virginia-North Carolina border. Two basic classification strategies were employed in determining the vegetation mapping capability of ERTS-1 data. The initial classification utilized unsupervised techniques which produced …

Isolation And Characterization Of Two Sterols From The Green Alga, Selenastrum Capricornutum, Raymond Mark Owings

Dissertations and Theses

The green alga, Selenastrum capricornutum, was cultured in artificial nutrient medium utilizing five-gallon carboys, each of which contained 16 1. of culture. The algal cells were separated from the nutrient medium by continuous-flow centrifugation at 7500 RPM, and were then lyophilized. The lyophilized cells were extracted by refluxing with ether, acetone, and chloroform:methanol (2:1). Free sterols and sterol esters were separated from the crude extract using preparative thin-layer chromatography. Sterol esters were saponified and both the sterols and the fatty acids were recovered.

Individual sterols were separated from the free sterol fraction using argentation thin-layer chromatography. Gas chromatograms, mass …

Impact Of Development Of Offshore Oil: East Coast Of South American Case Study, Aldo H. Brussoni

Marine Affairs Theses and Major Papers

To analyze this Coastal Management problem it is convenient to have a regional overview of the entire South Atlantic Coast (South America). Go over some of its physical characteristics, the state of development of the offshore oil industry, the volume of its activities, and other related data, the recreational and the fishing industries, the population and its characteristics. This will develop a regional comprehension which is absolutely necessary to have in mind before analyzing the problems of any particular situation created in a country or an area of a country of the Southwest Atlantic Coast. After covering, very generally, all …

Evaluation Of A Recreational Lake Rehabilitation Project, Clyde Brashier

2019: Dr. Clyde Brashier

Lake Herman, a recreational, shallow, warm water prairie lake near Madison, South Dakota drain in extensively cultivated watershed and acts as a siltation basin for a chain of four lakes. The lake is more than half silted in and since 1968 various rehabilitation efforts have been made, including the construction of silt traps and lake dredging.

Continuation of the monitoring of twenty plus chemical levels and biological populations of green algae, blue-green algae and diatoms has revealed two major changes: (1) ortho phosphate and total phosphorus levels (which increased markedly with the beginning of dredging) have decreased since dredging has …

Physical And Chemical Properties Of Outdoor Beef Cattle Feedlot Runoff, C. B. Gilbertson, J. R. Ellis, J. A. Nienaber, T. M. Mccalla, T. J. Klopfenstein

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Within the past decade, emphasis has been placed on the quality of our environment. Beef cattle feedlots have been singled out as a significant source of environmental pollution. Environmental protection provided by control facilities requires basic knowledge of the physical and chemical properties of feedlot runoff. This bulletin summarizes studies of physical and chemical properties of beef cattle feedlot runoff completed from August, 1968 through December, 1972.

Socioeconomic Impacts Of The Second Stage Of The Southern Nevada Water Project And Its Alternatives, William T. White, Bernard Malamud, John E. Nixon

Publications (WR)

This study evaluates the socioeconomic impacts of the Second Stage of the Southern Nevada Water Project of the United States Bureau of Reclamation, comparing that project with the alternatives of importing water from Nevada areas somewhat removed from the Las Vegas Valley and of leaving the water supply of the Valley basically as it is, the no project alternative.

The study follows, with adaptations and extensions, the general methodology for socioeconomic impact studies as developed and still being evolved in successive socioeconomic analyses of Bureau of Reclamation water projects. The methodology recognizes that the complexity of modern society and water …
