Ultrasonic Determination Of Thermoelastic Properties Of Stressed Solids, Engmin J. Chern

Dissertations, Theses, and Masters Projects

We present a thermoelastic derivation of ultrasonic waves propagating in a solid in which an applied homogeneous stress is superimposed on a nonzero initial stress. We also derive the temperature dependence of the elastic coefficients and the linear relationship between the applied stress and a newly defined parameter--the thermal acoustic constant. The stress acoustic constant is defined and its relationship to the acoustic natural velocity is discussed. Experimental considerations pertinent to the ultrasonic measurement techniques used in the investigation are described. The results of the stress-strain and thermal strain experiments verify the predictions of the theory. Finally, we derive an …

Phosphorus-31 Knigh Shifts In Amorphous Nickel-Phosphorus And Nickel-Cobalt-Phosphorus Alloys, Paul Stuart Gustafson

Dissertations, Theses, and Masters Projects

Amorphous alloys of the form Ni(,1-x)P(,x) and (Ni(,1-y)Co(,y))(,1-x)P(,x) were prepared by two methods, electroplating (EP) and electroless deposition (EL). Two metastable phases of differing physical densities and NMR properties were noted, and analysed by measurement of the Knight Shifts, relaxation times, physical densities, etc. A comparison is made between the data and a hybridized band model which yields an expression for the enhanced susceptibility of the phosphorous valence band.

The Structure Of Axisymmetric Turbulence, Charles W. Smith

Dissertations, Theses, and Masters Projects

A wide range of laboratory and naturally occurring plasmas are frequently attributed a fluid description and as such, demonstrate turbulent flows. We will investigate a variety of forms which may be taken by the correlation functions of these turbulent flows. The most commonly discussed isotropic symmetry is not generally applicable since most systems of interest have been shown to be strongly anisotropic. This thesis will develop an axi-symmetric description from which the magnetic helicity may be extracted together with its spectrum. This description will be compared to the form taken by axi-symmetric, helical Navier Stokes turbulence which will also be …

Nmr In Amorphous Vanadium Alloys, Larry Mattix

Dissertations, Theses, and Masters Projects

Amorphous alloys of VAl and VSi have been prepared by a process of r.f. sputtering onto cryogenic substrates. The Nuclear Magnetic Resonance has been examined in an effort to understand how the electronic structure of these amorphous alloys compares to that of the corresponding crystalline alloys, and to extend the study of the electronic properties of these alloy systems into composition ranges where the crystalline alloys do not exist, because of solubility limits.;The Al('27) and V('51) Knight shifts were measured at 77(DEGREES)K and 300(DEGREES)K, for Al concentrations extending from 15 to 85 atomic percent, in amorphous VAl. The results are …

Study To Investigate Source And Transport Route Of Marine Organisms (Hydroids And Bryozoans) In Hampton Roads And Current Velocity Profiles Of The Pier 12 Area, Naval Station, Norfolk, Virginia, Robert J. Diaz, Evon P. Ruzecki

Reports

Entrainment of the hydroid (Sertularia argentea) and the fleshly bryozoan (Alcyonidium verrilli) in the sea suction of deep draft naval vessels (carriers) in the area of the Norfolk Naval station has been a recurring problem since the early 60's. These fouling organisms (the term fouling is used in this report to indicate clogging of hull bottom intake grates and cooling system condenser tube sheets and not the growth of organisms on any part of the vessel) are winter species, growing only in the fall and winter and not the summer. Unfortunately they are also the most abundant and widely distributed …

Sediment Mixing By Invertebrates As Shown By 85kr1, Dexter S. Haven, Reinaldo Morales-Alamo, John N. Krauter

Reports

In the event radionuclides are accidentally introduced into an estuary, many isotopes would become adsorbed on suspended particles of clay or silt; others would be incorporated into living cellular material (Caritt and Goodgal, 1954; Rice and Willis, 1959). Oysters and other filter feeders in these estuaries are capable of filtering from suspension large quantities of the suspended solids, as well as the larger living cellular material (Haven and Morales-Alamo, 1966a). Ingested material along with the associated radionuclides would be voided as compacted fecal strings or pellets (biodeposits). Many of these fecal pellets may be alternately suspended in the water mass …

Morphology Of Udonella Caligorum Johnston, 1835, And The Position Of Udonellidae In The Systematics Of Platyhelminths, A. V. Ivanov

Reports

The platyhelminth, Udonella, lives on parasitic copepod crustaceans and, according to the present system of classification belongs to monogenetic trematodes (Monogena) among which it is usually placed in the group Monopisthocotylea (Fuhrmann, 1928; Bychowsky, 1937; Dawes, 1946; Sproston, 1946). However, the morphology of Udonella has not yet been studied thoroughly by anyone, and a number of unusual features of the structure, ontogenesis and biology of this form cause doubts with regard to its belonging to the Monogena.

Oyster Spatfall In Virginia Rivers: 1980 Annual Summary, Dexter S. Haven, Paul C. Kendall

Reports

The Virginia Institute of Marine Science (VIMS) conducts weekly surveys from June through early October to obtain oyster spatfall information. Spat counts are made from oyster shells strung on wire and suspended from stakes on public and private beds. The number of spat on shells are counted each week of the spawning season to determine the potential of a particular area for receiving a strike and to predict the most likely period the strikes will occur. Shells planted just before the period of maximum set have the best chance of getting a good strike.

Shoreline Erosion In Virginia, C. Scott Hardaway Jr., Gary L. Anderson

Reports

Virginia has over 5,000 miles of tidal shoreline. Several different shore types occur in the Tidewater region including the low-lying barrier islands of the Eastern Shore, the ocean front headland-barrier spit of southeastern Virginia, and the shores of the Chesapeake Bay and other estuaries which range from high bluffs to tidal marshes. In order to put shore erosion in proper perspective as a natural phenomenon, one must examine the recent geologic history of the region.

Much of shoreline erosion is a direct product of high energy storms like hurricanes and northeasters. The rate and amount of erosion along a specific …

Ecological Study Of The Tidal Segment Of The James River Encompassing Hog Point (Site Of The Surry Nuclear Power Station) : Completion Report, Robert A. Jordan, Patrica A. Goodwin, Charles E. Sutton

Reports

The Surry Power Station discharges cooling water into the transition zone of the James River. Phytoplankton, zooplankton, benthos, and fouling organism communities were sampled during the years 1969 through 1978, which encompassed a preoperational and an operational period. Temporal changes in the biotic communities followed seasonal patterns of temperature and salinity in the study area, and reflected inherent reproductive patterns of the organisms. Spatial patterns reflected the transport of organisms from the river in the vicinity of the intake to the zone encompassed by the discharge plume, as well as periodic bursts of meroplankton generation in the cooling water canals. …

Evaluating Impacts On Continental Shelf Environments, Concepts And Prospects, Donald F. Boesch

VIMS Books and Book Chapters

New and expanding activities on the continental shelf including disposal of wastes and dredged material, deepwater ports, floating nuclear power plants, mining, and oil and gas exploitation, have spawned increased interest in the ecology of continental shelf ecosystems and the environmental effects of these activities. Changing patterns of historical uses of the shelf environment, i.e., fishing and transportation, and as yet hypothetical new uses, such as tapping energy from the ocean's currents and gradients, will undoubtedly further increase our concern for the coastal oceans.

Kepone Monitoring At Skiffs Creek : In Fulfillment Of Contract Number Dacw65-79-C-0027, Harold D. Sloan, Michael E. Bender

Reports

Kepone entered the James River estuary from point sources of production and through runoff from unauthorized disposal sites in the vicinity of Hopewell, Virginia. The total quantity of Kepone released to the river is not known, however, about 1.5 x 106 kg were produced between 1966 and 1975. At present we estimate that 30,000 kg reside in contaminated sediments of the estuary.

Bed sediments are contaminated from the source at Hopewell to Hampton Roads, a distance of 88 kilometers. Patterns of contamination vary with sediment type and distance from the source. Major Kepone sinks exist in the Jamestown - Dancing …

Elizabeth River Surface Circulation Atlas, John C. Munday Jr., Hayden H. Gordon, Charles J. Alston

Reports

The Elizabeth River Surface Circulation Atlas is a compendium of maps which detail the surface circulation throughout the main branch of the Elizabeth River, in the port of Hampton Roads, Virginia. Data for the Atlas maps were obtained directly from field experiments using Remote Sensing and dye-emitting low-windage surface drogues. The maps show surface Lagrangian trajectories under various combinations of wind and tide. The Atlas is not intended to duplicate NOAA tidal current tables, but rather to supplement the tables with empirical trajectory data at increased spatial resolution. Knowledge of surface currents under different tide and wind conditions enables a …
