Energy Spectra Of Auto-Ionizing Electrons In Oxygen, M. Eugene Rudd, Kenneth Smith

M. Eugene Rudd Publications

Experimental and theoretical data are presented showing the energy spectra of auto-ionizing electrons from atomic oxygen. The experimental data were obtained by bombarding oxygen gas with 100-keV H⁺ and He⁺ ions; the theoretical results were obtained in a close-coupling calculation which coupled the ⁴S, ²D, and ²P terms of the ground-state configuration of O⁺ in electron-O⁺ scattering.

A Study Of The Precipitation Of Lead Bromide Fluoride At Low Ph Values In The Presence Of Boron, David W. Freund

Bachelors’ Theses

The determination of fluorine has been an important analytical problem for some time. Volumetric, gravimetric and instrumental methods have been used with some degree of success. Each of these methods have been limited in some way and no completely satisfactory method for the determination of fluorine has been found. The most popular of these methods is the determination of fluorine as lead chloride fluoride. This method has the advantage of giving reasonably accurate results and the lead chloride fluoride precipitate gives an excellent conversion factor for fluorine due to its high molecular weight. The procedure requires no special or expensive …

Surface Interactions Between Nickel Ions And Sodium Dodecyl Sulfate, Ralph Edward Coleman

Masters Theses

"In this research the interaction of nickel ions with the surfactant sodium dodecyl sulfate at the liquid-air interface was studied. Surface tension measurements were performed on pure sodium dodecyl sulfate solutions, with and without the addition of nickel ions. Results of these measurements showed that the addition of nickel ions lowered the equilibrium surface tension values of pure sodium dodecyl sulfate solutions and shifted the critical micelle concentration to lower concentrations. The foam fractionation technique was used to determine if the nickel ions could be removed from surfactant solutions. It was found that the removal of nickel ions was influenced …

Ecological Study Of The Effects Of Strip Mining On The Microbiology Of Streams, Ralph H. Weaver, Harry D. Nash

KWRRI Research Reports

The microflora of Cane Branch of Beaver Creek in McCreary County, Kentucky, which drains an area that was strip-mined between 1955 and 1959, was studied and compared with that of Helton Branch which drains a comparable area where there has been no mining. Differences include: the establishment of Ferrcbacillus ferrooxidans, for which procedures were developed for direct colony isolation from the stream; fewer saprophytic bacteria; more numerous and more diversified filamentous and unicellular fungi; and characteristic differences in algal flora. Representatives of 42 genera of filamentous fungi were identified. Of these, 21 were isolated only from Cane Branch. Representatives of …

Evaluation Of The Legal Institutions Of Diversion, Transfer, Storage, And Distribution Of Water In Kentucky, A. Dan Tarlock

KWRRI Research Reports

In 1966 Kentucky enacted a water use regulation statute which makes :important modifications in the common law doctrine of riparian rights by authorizing the state to grant permits for the use of water. The permit system is primarily designed to allow the state to gather the information necessary to conduct long range planning studies. However, the permit system can also be used to apportion water among competing users. The report examined the common law of riparian rights to determine how KRS Ch. 151 had modified it and analyzed some of the legal problems which could arise in the administration of …

Evaluation Of Runoff Coefficients From Small Natural Drainage Areas, Carlos Fix Miller, L. Douglas James

KWRRI Research Reports

The Kentucky Department of Highways, as do most other agencies which build small drainage structures, estimates flood peaks as the product of a runoff coefficient, a rainfall intensity, and the drainage area, Available procedures were applied to 39 gaged watersheds in and near Kentucky and compared with the results of frequency analysis of historical stream gage records. The methods consistently underestimated the flood peak.

Therefore, a more intensive study (using the Stanford Watershed Model) of the runoff coefficient was undertaken by dividing it into overland flow and streamflow components. A set of curves was developed based on the 50-year event …

Esthetic And Recreational Potential Of Small Naturalistic Streams Near Urban Areas, John A. Dearinger, Kenneth R. Harper, L. Douglas James

KWRRI Research Reports

The purpose of this study was to find a way to evaluate the esthetic and recreational potential of small streams and their watersheds. Research was limited to naturalistic streams with drainage areas under 100 square miles and located within 25 miles of a city. A methodology, based on some previous work of the U.S. Soil Conservation Service and the principles or concepts of terrain analysis, land use planning, value Judgment philosophy and the economics of outdoor recreation, was developed and applied in detail to two streams (Boone and Jessamine Creeks) near Lexington, Kentucky.

Evaluations were made of the streams' potential …

The Effects Of Geographical And Climatic Setting On The Economic Advantages Of Alternative Flood Control Measures, Clyde R. Dempsey, L. Douglas James

KWRRI Research Reports

It has long been realized that tributary urban development and channel improvement greatly affect the flow regime in a given watershed. A previous study used the Stanford Watershed Model to derive relationships expressing how the flood peaks in Sacramento, California, might be expected to vary with changing conditions of urbanization, channelization, and tributary drainage area. In order to observe the effects of climatic setting and geographical location on these relationships, the same type of analysis was applied to a drainage area near Louisville, Kentucky.

If reservoir storage is to be considered in a flood control program, it is necessary to …

Economic Analysis Of Flood Detention Storage By Digital Computer, James Ray Villines, L. Douglas James

KWRRI Research Reports

The objective of this study was to develop a digital computer procedure for preliminary analysis of the economic justification of reservoir detention storage for flood control and to present a sample study illustrating its application. A computer program called the University of Kentucky Flood Control Planning Program III was developed and tested on the flood plain of the South Fork of the Licking River in northeastern Kentucky.

Given a specified reservoir site and a downstream flood plain divided into planning units, Program III selects the economically efficient combination of reservoir detention storage and the associated combination of channel improvement, flood …

Some Ecological Observations On The Fathead Minnow, Pimephales Promelas, In The Alkaline Waters Of Nebraska, D. B. Mccarraher, Robert Thomas

Nebraska Game and Parks Commission: Staff Research Publications

Populations of the fathead minnow, Pimephales promelas, were apparently common throughout the sandhills region of Nebraska, prior to the appearance of the first pioneers, for Aughey (1880) listed the species as part of the native fauna. Current data relating to the distribution (Figure 1) and gross ecology of the species throughout the sandhills, was first collected in 1954 by the authors, with continuous observances recorded since that year. The fathead minnow is a common species throughout the northern great plains and appears to reach its greatest abundance in the shallow, alkaline lakes of Nebraska. Our investigations over the past …

The Ord River Regeneration Project. 3. Eight Years Of Progress, K Fitzgerald

Journal of the Department of Agriculture, Western Australia, Series 4

REGENERATION of degraded areas in regions of marginal rainfall is a slow process under the best of conditions, but on the Ord River Catchment, where much top-soil had been removed, the problem was unusually severe.

In many areas top-soil will have to be rebuilt before vegetation can be re-established.

This will be a long, slow process and regeneration will proceed through gradual plant succession from the "pioneer" annual species through to the permanent and more productive perennial species needed for a stable catchment area.

Ground Water Flow Systems Of Central Nevada, G. William Fiero Jr

UNLV Theses, Dissertations, Professional Papers, and Capstones

The U.S. Atomic Energy Commission has been evaluating a large area of central Nevada in order to define a supplemental test site for the underground testing of high-yield nuclear devices. Safety considerations involving the radiocontamination of the ground water in the vicinity of the test site necessitated that research be conducted to determine the direction and rate of flow of the ground water. This investigation defines the ground water flow systems in eighteen valleys comprising 12,000 square miles of central Nevada.

The definition of the systems was made following a compilation of existing hydrologic and geologic data for the area. …

The Fish Population Of Lake Poinsett, South Dakota, As Indicated By The Catch, James C. Congdon

Electronic Theses and Dissertations

Gill nets, trap nets, an otter trawl, and a boom-type electric shocker were utilized to obtain samples of the fish population of Lake Poinsett, South Dakota. The species and size composition of the samples differed significantly with time of season, time of day, location on the lake, and type of gear. Decreased activity following spawning was the apparent cause of a midsummer decline in gill net and trap net catches of black bullhead, black crappie, and white crappie. A late summer increase in the catch of yearling black bullheads, crappies, white bass, carp and bigmouth buffalo was attributed to an …

Ecological Relationships Of Breeding Blue-Winged Teal To Prairie Potholes, Roderick C. Drewien

Electronic Theses and Dissertations

Ecology and behavior of breeding blue-winged teal (Anas discors) were studied in northeastern Day County, South Dakota in 1965 and 1966. Breeding pair use of the wetland habitat and importance of Type 1 ponds in the wetland complex were evaluated. Pair densities of 30.7 and 33.0 per square mile in 1965 and 1966, respectively, were above the 16-year average from 1950-66 and near maximum. Blue-winged teal comprised 46.7 percent of the waterfowl breeding population in 1965 and 51.7 percent in 1966. Number of water areas per square mile through mid-spring 1965 was comparable to the average for the 16-year period …

Life History And Ecology Of The Black-Footed Ferret In The Wild, Conrad N. Hillman

Electronic Theses and Dissertations

Twenty-one black-footed ferrets (Mustela nigripes) were observed at six different locations in southwest South Dakota between April 1966, and September 1967. All observations were made on black-tailed prairie-dog (Cynomys ludovicianus) towns from 15 to 100 acres in size. Because of the proximity of towns inhabited by ferrets, it was possible that individual animals were observed in more than one location. Three litters of ferrets were studied. Young ferrets were most active during early morning and late evening hours. Ferrets remained as a group until early fall when dispersal evidently occurred. Young ferrets accepted live-tethered and dead prairie dogs, mice, cottontails …

Food Habits And Energy Utilization Of Badgers, Grant K. Jense

Electronic Theses and Dissertations

A study was initiated in 1966 to determine food habits and energy utilization of badgers. Digestive tracts were collected in eastern South Dakota from November 1966 to November 1967. A male and a female badger were used for two energy-balance and three digestion trials. Ground squirrels, mice and rabbits were found to be the most important mammal foods eaten. Birds and eggs were only eaten during spring and summer. Toads and grains were important fall foods. Insects were eaten throughout the year but usually only in trace amounts. However, when available, badgers ate large quantities of beetles and ground-nesting bees. …

A Survey Of Pollution On Selected Streams In The Black Hills Of South Dakota, Thomas J. Jurgens

Electronic Theses and Dissertations

Seven Streams in the Black Hill of South Dakota were surveyed to determine the influence of suspected sources of pollution on these streams. The sources of pollution included both sewage treatment plant effluents and mining wastes. A comparison of the benthic fauna community below a pollution source to that above it was the primary basis for evaluating the effect of the pollution source on the stream. The results of the benthic fauna samples indicated that the streams surveyed were being polluted. The degree of pollution of each stream was also indicated by these results. Chemical analysis were sued to verify …

Movements And Behavior Of Pheasants During The Breeding Cycle As Determined By Radio-Tracking, Thomas L. Kuck

Electronic Theses and Dissertations

Behavior and movement studies were carried out on the Rifle-Calahan Study area, Sanborn County, South Dakota, in 1965 and 1966. Objectives of the study were to evaluate radio telemetry techniques, determine the territorial area and home range of the hen and cock, study the behavior pattern of hen and cock in the harem makeup, determine the distance traveled by the hen when attracted to the harem, determine if the hen nests in the immediate area of the crowing territory, and study the behavior of the hen while nesting and caring for the brood. Twenty adult pheasants (16 hens and 4 …

Fishes Of The Big Sioux River, James A. Sinning

Electronic Theses and Dissertations

An understanding of the fishes and limnology of a river is essential to the effective management of the river. The climate, soils, and agricultural practices in eastern South Dakota create unusual characteristics in rivers draining that area. One of the principal rivers of the area is the Big Sioux River. Fishes of this river were first studied about 1900 by Meek and by Everman and Cox (Bailey and Allum, 1962). A later survey by Churchill and Over (1933) apparently included the Big Sioux River, but collection data were inadequate for detailed comparisons. Since that time collections of fishes were made …
