Stability And Local Effects Of An Offshore Sand Storage Mound, Dam Neck Disposal Site, Virginia Inner Continental Shelf, William Joslyn Saumsiegle

OES Theses and Dissertations

From 1967 to 1974 medium to coarse sand dredged from the Chesapeake Bay was stockpiled approximately three miles offshore of Dam Neck, Virginia in hopes that the sand could be recovered for local beach renourishment projects. The resulting mound was surveyed over a two year period to determine if the sand is being removed by wave and current action and if the creation of a new feature on the ocean bottom changes the wave refraction patterns and perhaps creates local erosion.

Bathymetric profiles across the storage mound show some apparent morphological changes, but a detailed analysis of this data is …

Kinetic And Binding Studies On L-∝-Glycerophosphate Dehydrogenase, Paul Richard Rosevear

Chemistry & Biochemistry Theses & Dissertations

The properties of the coenzyme, NAD, binding site of chicken muscle L-∝-glycerophosphate dehydrogenase were studied. Adenosine monophosphate, adenosine diphosphate and adenosine diphosphoribose were sha.vn to inhibit the enzyme competitively with respect to NAD. The presence of adenosine, pyrophosphate and ribose regions in the coenzyme binding site of the enzyme was suggested by the inhibitor constants obtained for these compounds.

Disodium monoalkyl phosphates, n-butyl to n-dodecyl phosphate, inclusive, were also shown to inhibit the L-∝-glycerophosphate dehydrogenase catalized reaction competitively with respect to NAD. A positive chain length effect was observed in the binding of these compounds to the enzyme, suggesting the …

Similitude Of Mass Transfer Processes In Distorted Froude Model Of An Estuary, Carvel Hall Blair

Mechanical & Aerospace Engineering Theses & Dissertations

The project began with the design and construction of a hydraulic Froude model of the Lafayette River, a small well mixed estuary in Norfolk, Virginia. Horizontal scale is 1/540, vertical scale 1/12 yielding a vertical distortion of 45. Adjustment by roughness strips and screens produced close agreement of model-prototype tide heights, currents, and salinities in the deep reaches comprising 80% of the estuary volume. Some scale effect in velocity and tide height could not be eliminated in the shallow upper branches of the estuary, probably because of the high geometric distortion and the narrowness of the channel at kilometer 6.7. …

An Efficient Dft Algorithm Using The Walsh Transform, Albert P. Gerheim

Electrical & Computer Engineering Theses & Dissertations

The matrix transformation relating the sequency and frequency domains is derived. It is shown that these­ frequency-to-frequency conversion can be performed via a computationally efficient sparse matrix algorithm. The sequency-to-frequency algorithm can be used with a fast Hadamard transform to implement a discrete Fourier trans­ form. The efficiencies of this combined algorithm and a radix-two fast Fourier transform are compared.

The algorithm is applied to the sequency domain de­ sign of a Wiener digital filter. Improved computational efficiencies are achieved relative to the procedure de­veloped by Kahveci and Hall (9).

The Effects Of Central And Peripheral Graphics On Personal Disclosure, Louis C. Saksen

Psychology Theses & Dissertations

Forty-eight college students, twenty males and twenty-eight females, were used to assess the effects of central and peripheral graphic environments on personal disclosure and subjective evaluation. Scales developed by Cash (1972) were used to determine the type and amount of subjects' disclosure and non-disclosure; scales developed by Nehrabian and Russell (1974) were utilized to assess subjective evaluation of the environmental space in terms of information theory and approach-avoidance.

Results replicated a previous study by Cash (1974), indicating that females made more positive self-references than males (p < .01) . Hales also chose to disclose less often than females (p < .05) . No significant differences resulted from the graphic environmental conditions.

The data did produce substantial variance between the sexes in response to the environments. …

An Engineering Solution To Improve Water Quality In A Tidal Lagoon, Richard Warren Price

Civil & Environmental Engineering Theses & Dissertations

Rising demand for better water quality stimulated research and development of ways to improve the quality level in existing as well as proposed water systems. At present, most of the solutions focus on biological and chemical processes.

Many natural or man-made water bodies act as receivers for both point and non-point pollution sources. Employment of biological and chemical treatment has proved successful in many of these cases; however, in some cases a more natural physical solution of an engineering mode would be more desirable. A "flushing" technique using the tidal fluctuation as a driving force has been investigated and the …
