Winter Behavior And Population Dynamics Of American Eagles In Western Utah, Clyde C. Edwards

Theses and Dissertations

The large size, extensive range, and irnporta.nt corrnnunity role of the Golden Eagle (Aguila chrysaetos L.) and the Bald Eagle (Haliae-etus leucocephalus L.) attract considerable scientific interest. Sorne aspects of their life history have been investigated and reported in detail, but their rapidly declining numbers (Sprunt and Ligas 1966, Cottam 1961) necessitate new investigations into all phases of their life history and particularly into population dynamics.

An Optimization Technique Applied To The Determination Of Orthotropic Material Properties Using Dynamic Response Test Data, Ronald L. Webster

Theses and Dissertations

A knowledge of the behavior of a material under loading similar to expected service loading is required before that material can be used effectively in the design process. Without sufficient mechanical properties data, the design process degenerates to a time consuming and often costly "build, test and modify" type of program. Obviously, this trial and error approach leaves much to be desired.

Analytical Study Of Heat Conduction And Thermal Stress In Solids With Pressure Dependent Contact Resistance, Dhruvkumar S. Patel

Theses and Dissertations

In the usual thermal stress analysis of a body, the stresses are found for a predetermined temperature distribution. In problems involving composite materials, thermal contact resistance between materials can significantly affect the temperature distribution. The contact resistance is normally a function of the contact pressure and thermally induced stresses can affect the temperature distribution. Thus in composite bodies the thermal stress problem and the heat transfer problem may be coupled and require a simultaneous solution of both problems.

The Role Of Serious Music In The Development Of American Radio, 1920-1938, Robert Huchette Wilkins

Theses and Dissertations

Before the advent of broadcasting in 1920, well- performed, serious music was a monopoly of large population centers. Except for tne phonograph, the repertoire cf which was extremely limited and flawed by technical inadequacies, most Americans had little opportunity to hear good music. From its beginnings, radio depended on music for a large part of its programming. Initially the repertoire differed little from that of the phonograph, but wit.2 the establishment of the networks in 1926/192?, the ser:.ous-music repertoire expanded to include full-length works from the baroque through the contemporary periods. Conductors like Bamrosch, Howard Barlow, Stokowski, and Toscanini, among …

Mechanism Of Water Transport Through Reverse Osmotic Membranes, Cheryl Kay Murphy

Theses and Dissertations

Cellulose acetate membranes show a higher permeability to water than to salt and are being used for desalination of salt water by reverse osmosis. Use of highly acetylated cellulose membranes give a higher salt rejection but also decrease flow rate of the water. The addition of very-short-chain substances or alkyl groups larger than one carbon atom to the cellulose membrane also decreases water flux. A proposed mechanism of transport through the membrane is that the water molecule is passed along the chain by hydrogen bonding with the acetyl groups, The NMR shows a change in the chemical shift of water …

Solubilization Of Lignite Under Hydrogen Pressure In Various Organic Solvents, Eddie Keh-Chen Yuan

Theses and Dissertations

The solution-hydrogenation of Baukol-Noonan lignite, from Burke County, North Dakota, was undertaken in a microautoclave with various organic solvents. The reactor was charged with pulverized lignite and solvent (mixture) in a 1:4 ratio by weight. The reaction conditions were 735-750°F, 1500 psig. initial hydrogen pressure and two hours of reaction time at temperature and pressure.

The percent solubilization of lignite was calculated from the weight of residue recovered and initial weight of lignite charged. It was found that a hydroaromatic ring which was polarized by a nitrogen atom or coupled with a benzene ring was an effective solvent for lignite. …

The Controlled Oxidation Of Lignite In A Fixed Bed, Leroy Dockter

Theses and Dissertations

The use of cooling coils or pipes to control the reaction zone temperatures when oxidizing lignite in a fixed bed was studied. The experimental procedures involved passing heated air through a bed of lignite to initiate spontaneous heating and then removing the heat generated using a water cooled coil. Variables investigated included the lignite moisture content, prior oxidation history, and lignite source.

Spontaneous heating was initiated in lignite from three different mines, and at initial moisture contents from bed moisture down to 10 percent by heating the lignite to 250-260 °F while passing air slowly through the bed. At moisture …

Rheological Study Of Concentrated Silica Suspensions, Prakash N. Mishra

Theses and Dissertations

Concentrated suspensions of silica in water were investigated using a rotational viscometer and a Zeta-Meter. The viscometric data was analyzed for shear dependence, solid concentration dependence and pH dependence. The data for electrophoretic mobility was analyzed for pH dependence.

The experimental data was applied to the Bingham plastic model and the power law model and the power law model was found to describe the experimental data more closely than the Bingham plastic model. The parameters for these two models were correlated to solids concentration, pH and electrophoretic mobility.

Effect of particle size on apparent viscosity was also studied but no …

A Study Of Turbulent Heat Transfer From A Flat Plate With Transverse Temperature Variations, John C. W. Kwan

Theses and Dissertations

Heat transfer in turbulent flow from external surfaces has been investigated extensively in the past. Most of the theoretical and experimental work deals with a two dimensional boundary layer on isothermal or uniform heat flux surfaces with longitudinal temperature variation. However, little attention has ever been paid to the case in which the temperature of the plate varies transversely. This is a three dimensional problem due to the spanwise variation of the thermal boundary layer. The most elementary example of this is the boundary formed by the sudden temperature impulse that acts transversely across a flat plate as shown in …
