Natural Salinity Removal Processes In Reservoirs, Jay J. Messer, Eugene K. Israelsen, V. Dean Adams

Reports

A small but significant amount of salinity removal has been reported by various authors to occur in mainstem Colorado River reservoirs. Recalculation of some of these salinity budgets, together with a review of the data bases used, usggests taht removal has not often been conclusively demonstrated. Laboratory microcosm experiments and field data indicate that calcium carbonate precipitation, perhaps with some coprecipitation of magnesium carbonate, is the mechanism responsible for most of the salinity removal in Oneida Reservoir, Idaho. Coprecipitation processes (including ion exchange), coagulation, and bioassimilation do not appear to be important natural salinity removal mechanisms. Finally, loss of calcium, …

The Potential For Groundwater Contamination Along Basin Margins In The Arid West: Alluvial Fans And Lake Features, Calvin G. Clyde, Robert Q. Oaks, Peter T. Kolesar, Edward P. Fisk

Reports

Many towns of the arid west were built upon alluvial fans and upon sites underlain by Pleistocene lake deposits. The objective of this study was to assess the potential impact of these activities of man upon groundwater quality within these geological features. Emphasis was placed on shallow groundwater quality after it was determined that deep groundwater is rarely contaminated at such sites. A reconnaissance of Utah and Nevada was made and four sites underlain by alluvial fans (Willard, Manti, Elsinore, and Spring City) and four sites underlain by lake shore deposits (Hyde Park, Fielding, Providence and Richmond) were selected in …

Water Quality In Pleasant Valley, Utah, Calvin G. Clyde, Dennis B. George, Kun Mo Lee, Phil Pucel, William Hay

Reports

Pollution of shallow groundwater due to wastewater disposal in Pleasant Valley, Utah, was investigated from October 1979 through August 1980. Water samples were collected from 23 wells and 5 stream sampling sites. Water quality analysis revealed pollution at several sites. Groundwater pollution caused by man’s activities in the area was observed in Bolotas and Scofield Campsite subdivisions. Severe shallow groundwater pollution measured in wells which were located in south and north profiles of the town of Scofield, Utah, could have originated from the municipal waste disposal practice in the town. Natural phenomena, however, such as pyrite oxidation, could possible have …

The problem of creating a practical computational tool to perform transient contingency analysis in a power system control center is considered. The computer program developed may be used in a control center computer where a state estimation program or a consistent set of load flow data is available. It can be run on a periodic basis over a previously specified contingency list, or it can be called by the system operator to analyze a particular contingency. The transient behavior of the system is evaluated based on a simulation technique widely acknowledged for its fast solutions. The method uses rapidly convergent …

A Study Of Industrial Arts Teachers' Opinions Of Gifted And Talented Students In Black Hawk County, Iowa, James Robert Wrona

Dissertations and Theses @ UNI

While the handicapped and disadvantaged have enjoyed the benefit of some unique industrial arts educational programming, relatively little has been done to provide for the special educational needs of gifted and talented students. This may be partially a result of little research completed associating the gifted and talented student with industrial arts. Additionally, legislative support for gifted and talented students has been lacking. It was not until 1978, with the passage of Public Law 95-561, that programs for gifted and talented students have been granted some funding on the federal level. Although this public law can authorize up to $35 …

Chemical Spray Pyrolysis Of Cadmium Telluride., Alok K. Berry

Masters Theses

"Chemical spray pyrolysis is a technique for film growth which is of interest because of its potential for very large scale, inexpensive production of polycrystalline thin film semiconductor materials. Cadmium telluride shows promise as a base material for solar cell applications. Thin films of CdTe have been spray deposited on glass substrates from an aqueous solution containing CdC1₂, Teo₂ and a reducing agent. The films show a zinc blende structure and appear to be intrinsic. Microprobe analysis indicate an excess of Cd, but this is not detectable by X-ray diffraction. The photo absorption studies indicate a direct …

Optical Phase Modulation Utilizing Magnetoelastic Properties Of Metallic Glasses, Frank R. Trowbridge

Retrospective Theses and Dissertations

Three different optical fiber phase modulators utilizing the magnetostrictive properties of the metallic glass alloy Fe74Co10B16 were constructed. By binding the optical fiber to the magnetostrictive metallic glass, the strain imparted to the metallic glass from the magnetic field is transferred to the optical fiber. The strain on the optical fiber shifts the phase of the light, which can be controlled indirectly by varying the current producing the magnetic field permeating the metallic glass. The performance of the modulators on the basis of optical phase shift as a function of bias magnetic field and optical phase shift as a function …

The Need For A Schema For The Classification Of Transitional (Shale) Materials, Robert C. Deen

Kentucky Transportation Center Research Report

The need for comprehensive information on the characteristics and behavior of earth materials has been recognized for many years, perhaps for as long as significant construction has taken place in and on the surface of the earth. In recent years, however, the magnitude and complexity of engineered construction has greatly increased, resulting in a corresponding increase in the need for information on the engineering properties of soil and rock materials for use in site selection, design, construction, and maintenance of major structures. Probably the most pressing need for such data is for use in preliminary considerations of site selection and …
