Social And Cultural Impact Of A Proposed Reservoir On A Rural Kentucky School District, Charles R. Smith, Philip Drucker
Social And Cultural Impact Of A Proposed Reservoir On A Rural Kentucky School District, Charles R. Smith, Philip Drucker
KWRRI Research Reports
This study utilizes anthropological concepts and research methods to study the educational system of a Central Kentucky school district with the goal of predicting the impact on it of a proposed multi-purpose (flood control, recreation, etc.) reservoir, and proposing options for forestalling dysfunctional aspects of that impact. The impact will result from the fact that although the county is now rurally oriented, the proposed reservoir will attract (has already begun to attract) urbanite residents from nearby Louisville, Kentucky's largest urban center, who can be expected to bring urban values concerning education, as well as other areas. To assess probable directions …
A Study Of Organochlorine Insecticides In Freshwater Crayfish -- Analytical Problems And Biomonitoring Survey, Robert C. Vanderjack
A Study Of Organochlorine Insecticides In Freshwater Crayfish -- Analytical Problems And Biomonitoring Survey, Robert C. Vanderjack
Masters Theses
Crayfish were collected from 3 sites on Polecat Creek, Coles County, Illinois in early spring, early summer, and late summer of 1972. Pesticides were extracted from the crayfish tissue in a one step procedure utilizing a Florisil elution column. Analysis was by electron capture gas chromatography. Pesticide residues in the nannogram range were analyzed and background contamination was an important consideration. Sources of background contamination were investigated and teflon stopcocks, Florisil, and residues on “cleaned” glassware were found to be major contamination sources. Distilled water used in flushing glassware should also be considered a potential contamination source.

Chemical Survey Of Selected South Dakota Lake Sediments, Alan Ross Swanson
Electronic Theses and Dissertations
Available phosphorus, organic carbon, and organic nitrogen were measured in bottom sediments of 16 lakes and ponds in northeast South Dakota. These lakes were glaciated, relatively shallow, and productive. Ranges of the surface sediments were: available phosphorus, 2 to 42 ppm; organic carbon, 0.94 to 5.34 percent; and organic nitrogen, 0.29 to 0.79 percent. Ranges of subsurface sediments were: available phosphorus, 2 to 39 ppm; organic carbon, 0.54 to 6.06 percent; organic nitrogen, 0.19 to 0.88 percent. Concentrations in most lakes varied little from top to bottom. Hard-bottomed lakes generally decreased in nutrient concentrations from sediment surface of subsurface. Lower …
Origin And Transport Of Nutrients In The Upper Big Sioux River, South Dakota, Charles William Thompson
Origin And Transport Of Nutrients In The Upper Big Sioux River, South Dakota, Charles William Thompson
Electronic Theses and Dissertations
The upper Big Sioux River Basin, in northeastern South Dakota, was studied to determine the origin and transport of nutrients in the Big Sioux River. The area was divided into three segments. Two of the segments, the Big Sioux River and Willow Creek Basins, were primarily agricultural drainage areas, and one segment was the city of Watertown. Sampling stations were selected to facilitate the determination of nutrient inputs to the river from each of these segments and to determine the nutrient load in the river leaving the study area. Nutrients studied included total orthophosphate and the particulate and dissolved fractions …

The Investigation Of Snowfall Rate Using Optical Techniques, Gerald J. Mulvey
The Investigation Of Snowfall Rate Using Optical Techniques, Gerald J. Mulvey
Atmospheric and Environmental Sciences Theses and Dissertations
Experiments involving the attenuation of light by falling snow, or hydrometeors in general, lend themselves to the study of at least two problems of meteorological interest. The first problem is that of visibility in adverse weather conditions, and the second is that of finding a better method to measure precipitation. From the late 1940's through the late 1960's, various investigators have attempted to apply forward light scattering theory in the geometric optics range (α ≥ 200, where α = (2π_r)/λ, λ=wavelength and r = radius)* to quantitatively describe the attenuation of a light beam, and thereby visibility changes due to …

Grey Kangaroo Management Programme, Department Of Agriculture, Western Australia
Grey Kangaroo Management Programme, Department Of Agriculture, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
The Grey Kangaroo Management Programme, introduced in 1971 by the Department of Fisheries and Fauna, is designed to ensure the long-term conservation of the grey kangaroo, while at the same time recognising the right of the landholder to protect his primary production from damage.
One of the points which has arisen after examination of the programme is that some individual farmers are not fully aware of the requirements of the regulations.

D.C. Background On Predator Control Legislation, Michael Frome
D.C. Background On Predator Control Legislation, Michael Frome
Great Plains Wildlife Damage Control Workshop Proceedings
The tragic fiasco of federal predator control as we have known it is finished. The American people will no longer tolerate it. In this age of environmental concern, the people will not allow their tax dollars to be diverted for such a destructive and wasteful war against living wild creatures for the exclusive benefit of the sheep industry. There is now no turning back to old ways.
Indiscriminate trapping, shooting and poisoning have reduced some of the rarest, most beautiful and superbly adapted species of our wildlife heritage to the brink of extinction, although they consitutue a resource that could …
How Important Are Livestock Management Methods To The Orevention And /Or Reduction Of Losses To Coyotes, Don Good
Great Plains Wildlife Damage Control Workshop Proceedings
Professor.E. K. Faulkner, Extension Sheep Specialist from the University of Wyoming, stated that fencing the range was too expensive to be practical. He indicated that flares, pop-guns, color painting on sheep, and dogs have been used to cut down losses to coyotes but these methods have not been nearly so effective as the use of cyanide guns and 1080. He also indicated that losses to coyotes along with labor problems are the number 1 and 2 reasons for 200 sheepmen going out of the business the past 5 years in the range country. He said that shed lambing or lambing …
The Sport Hunting Of Coyotes, Edward L. Kozicky
The Sport Hunting Of Coyotes, Edward L. Kozicky
Great Plains Wildlife Damage Control Workshop Proceedings
In an effort to gain some insight into the sport hunting of coyotes in Kansas, Bob Henderson circulated 586 detailed questionnaires and received 228 replies--an excellent voluntary response.
Time does not permit detailed comments on each question and reply. We shall only hit the highlights, and add some editorial comment where it seems appropriate.
It should be remembered that those who took the time to answer the 35 questions were devotees of the sport. This point is emphasized by the fact that of the 225 hunters who responded, 95 have been hunting coyotes for 20 years or more. The next …
Sport Hunting As A Method Of Damage Control, L. Boddicker
Sport Hunting As A Method Of Damage Control, L. Boddicker
Great Plains Wildlife Damage Control Workshop Proceedings
Predator damage control is an area of concern to the livestock producer. He is also often the most likely person to choose sport hunting of coyotes as a recreational activity. Sport hunting of problem coyotes can be an effective tool.
Agricultural producers want to know the skills to control depredating wildlife. A high powered rifle, traps, and various related equipment are standard for most livestock production operations.
Through the Extension effort we attempt to help the producer develop wildlife damage control skills. It is also our responsibility to help develop alternatives to aid the livestock producer with persistent wildlife damage …
Regional Hydrothermal Alteration Of The Leadville Limestone (Mississippian) Of Central Colorado, L. V. Benson
Regional Hydrothermal Alteration Of The Leadville Limestone (Mississippian) Of Central Colorado, L. V. Benson
United States Geological Survey: Staff Publications
Massive metallic-sulfide deposits were implaced in the Leadville Limestone {Mississippian) of Central Colorado less than 70 million years ago. The thermal fluids which precipitated ore at Gilman, Colorado have regionally altered the Leadville Limestone. The sequence of alteration began with the recrystallization of limestone to a dark medium~grained dolomite containing a homogeneous distribution of Fe. This Was followed by partial recrystallization of the medium-grained dolomite to coarse-clear dolomite which contains an inhomogeneous distribution of Fe. The resulting banded rock is known as "zebra rock" . Precipitation of Si0 2 (jasperoid) occurred next. The jaspe=oid formed prior to the deposition of …
Environmental Improvement: A Concept For Harbor Maintenance Programs For Long Island Sound, John-Robert Curtin
Environmental Improvement: A Concept For Harbor Maintenance Programs For Long Island Sound, John-Robert Curtin
Marine Affairs Theses and Major Papers
This paper suggests a comprehensive approach to maintenance dredging and maintenance dredge disposal for Connecticut in a carefully-regulated manner that will improve, rather than impair, the natural quality of the Sound. It proposes an interim measure that would allow for the continued operation of Connecticuts Commercial Harbor areas until a permanent program, together with the necessary technological advances, can be implemented to handle dredge disposal. This paper is based on data presently available on New Haven Harbor, presented in a report on the environmental quality of dredge spoils proposed to be removed from one area within New Haven Harbor known …

Offshore Oil Interests Of The United States: An Overview, Scott H. Marstan
Marine Affairs Theses and Major Papers
The following discussion focuses on the current situation as regards U.S. oil interests worldwide offshore. It divides into three general areas: 1) a general view of the scope of the U.S. oil companies' investments offshore, foreign and domestic, 2) an analysis of the recent rise to power of the Organization of Petroleum Exporting Countries (OPEC) and the ensuing problems created for U.S. oil investments abroad, and 3) a brief history and a discussion of U.S. oil interests in the law of the sea as an expression of their concern for resolution to OPEC-like problems.
Characterization Of Water Movement Into And Through Soils During And Immediately After Rainstorms, C. T. Haan
Characterization Of Water Movement Into And Through Soils During And Immediately After Rainstorms, C. T. Haan
KWRRI Research Reports
The movement of water into and through soils in the unsaturated state is basic to many water resources problems including rainfall-runoff models, ground water recharge, irrigation, drainage, evapotranspiration and the movement of pollutants in soils. This study was conducted in an effort to determine if the flow equation based on Darcy's Law and the continuity equation could be used to describe watershed infiltration and thus be incorporated into hydrologic models.
The results of the study indicate that even on apparently uniform soils there is a great deal of variability in soil water properties. Handling this variability plus the difficulty of …
Groundwater - Surface Water Integration Study In The Grand Prairie Of Arkansas, Carl L. Griffis
Groundwater - Surface Water Integration Study In The Grand Prairie Of Arkansas, Carl L. Griffis
Arkansas Water Resources Center Technical Reports
A mathematical model of the Quaternary Aquifer of the Grand Prairie, Arkansas was developed and used to evaluate a variety of methods of artificially recharging this aquifer. In addition, the model was used to evaluate the impact of various levels of water management and the probable movement of artificially recharged water in the aquifer. Improved water management and the use of recharge wells were the two alternatives that showed the most promise as potential solutions. The rate of movement of recharged water was determined by the model to be 300 ft./year under a gradient of 16 ft./mile.
