The Anodic Oxidation Of Crotonic Acid In Basic Solutions, Richard C. Porter

Masters Theses

"The purpose of this study was to investigate the anodic oxidation of crotonic acid in basic solutions. Potassium hydroxide solutions of pH 12.3 and KOH-K₂CO₃ solutions of pH 11.5 and 10.5 were used. The investigation was carried out on platinized-platinum anodes at 80°C.

Experimental studies were conducted to determine the effects of crotonic acid concentration, pH, and temperature on the current. Faradaic efficiency was determined by analysis of CO₂ produced and was approximately 100 per cent.

The results were interpreted in terms of a mechanism having the following characteristics:

1. The first electron transfer is the rate …

A Study Of Sedimentation In A Well Regulated Major Drainage Basin - The Monongehala, Allegheny And Upper Ohio Rivers, William S. Wood

Masters Theses

"This investigation is concerned with the study of various programs employed in reducing and controlling sediment. The measures employed by the U.S. Soil Conservation and Forestry Services to control and reduce erosion, the primary source of sediment, was studied. The flood control and river navigation structures constructed and operated by the U.S. Army Corps of Engineers and the effect of these structures on sedimentation was also evaluated. State and local community regulation and control of exploited natural resources was studied to determine their influence on the generation and control of sediment.
The Allegheny, Monongehala and upper Ohio River Drainage Basin …

Suggestions are made as to its usage at higher frequencies"--Abstract, page ii.

A Numerical Solution For Beam-Columns On Non-Linear Foundations, Wendelin H. Mueller Iii

Masters Theses

"A program for Matlock's recursive method, a numerical method which will analyze beams and columns with linearly varying spring supports, was modified to enable the solution of such members supported by non-linear springs. This modification was accomplished by an iterative technique. The final result of this paper is a computer program which can be used to solve beams or columns with non-linear spring supports, giving as output the deflection, slope, moment, shear, net load and curvature of the structure at uniformly spaced locations"--Abstract, page ii.

A Fluid Control System For Nuclear Reactors, Roger Alan Crane

Masters Theses

"This thesis presents both an experimental and analytical analysis of the scram characteristics of a fluid control system for a nuclear reactor. This control system utilizes a control tube containing a neutron-absorbing fluid. The level of the fluid inside of the tube is then regulated by means of' a pressurized gas and offers a number of unique advantages over the conventional control rod system using linear absorber rods.

The effect of varying the level-control pressure and initial height of the fluid column is determined and evaluated. The time required to complete a scram with the fluid control system is compared …

A Numerical Method For The Solution Of Cylindrical Shell Structures, Chen-Jow Hsiao

Masters Theses

"Many studies and analyses of shell structures to date have been either so complex and laborious as to preclude their application in practical design problems or so approximate, because of basic assumptions, as to limit their scope of application. Hence, a method of shell analysis which is convenient to use, reasonable in its results and general in its application is really needed. It is the purpose of this study to supply such a method of analysis.

In this investigation it is proposed to replace the shell structure which has an infinite number of degrees of indeterminancy with an analogous framework …

An Analysis Of Neutron Resonance Detectors In Critical Uranyl-Fluoride Heavy Water Systems., William H. Roach

Nuclear Engineering ETDs

The measurement of neutron flux spectra in reactors is a problem which can be approached in several ways, depending on the information desired. For high energy measurements, threshold detectors are often used; if spatial information of the flux is required, some type of fission detector may be employed. For flux magnitude measurements in the epithermal energy range, foils of elements which have strong neutron absorption resonances are commonly utilized. If the resonance is sufficiently isolated from other resonances and the contribution from the resonance to the total resonance absorption integral of the element is large, then it is a fairly …

Mine Acid Drainage And Associated Flow Fluctuations, Henry Constantin Carroll

Graduate Theses, Dissertations, and Problem Reports (ETD)

The Left Fork of Little Sandy Creek Basin, between Fellowsville and Tunnelton, West Virginia, was surveyed for the location of mine acide drainage sources. Thereafter, they were studied for the purposes of planning abatement and determining the relationship between the chemical constituents in and the discharge of mine acid drainage.

Nonparametric Detection Of Signals Causing Arbitrary Changes In The Accompanying Noise Backgrounds, John Joseph Komo

Doctoral Dissertations

"The detection of signals in the presence of noise is an important problem in the field of communications. The detection problem is concerned with the design of systems which determine only the presence or absence of a signal which occurs with background noise. An example of considerable importance, which is encountered quite frequently in practice, is the radar detection problem. In the radar problem it is desired to determine the presence of a target by detecting the presence of a radar return signal in noise. Another example is the seismic exploration problem which utilizes the detection of reflected signals from …

A Study Of The Supercooling Behavior Of High Purity Liquid Bismuth, B. L. Bramfitt

Doctoral Dissertations

"This investigation involves a study of the supercooling behavior of pure bismuth as affected by the melting atmosphere, the amount of superheat, and the intentional addition of metallic and non-metallic foreign materials to the melt. It was found that the amount of oxide on the melt surface is a controlling factor in the degree of supercooling obtainable in bismuth. In the presence of a thick bismuth oxide surface layer the amount of superheat below a 15°C drastically decreases the amount of supercooling due to the retention of nuclei in the surface film that promote nucleation upon cooling of the melt. …

The Anodic Dissolution Of Cadmium In Aqueous Solutions, San-Cheng Lai

Doctoral Dissertations

"The purpose of this investigation was to study the effect of cadmium ions on the anodic dissolution of cadmium in salt solutions of ·constant ionic strength. The concentration of the cadmium ions was varied from 0.001 to 1 N and the current density ranged from 0.001 to 0.1 amp•cm^-2. The temperature was controlled at 25°C.

....A mathematical model was postulated expressing the anodic dissolution rate as the sum of electrochemical, local corrosion, and disintegration rates."--Abstract, page iii.
