The Kara Sea: Geologic Structure And Water Characteristics, Donald B. Milligan

Dissertations, Theses, and Masters Projects

Movement of Atlantic Water into the Kara Sea is controlled by the bathymetry which funnels the inflow up three canyons along the eastern margin of the Svyataya Anna Trough. Mixing of the warm, saline Atlantic Water in these canyons with the considerable summer outflow of the Ob-Yenisey rivers results in the formation of Arctic Bottom Water and due to the presence and cooling by ice, in the formation of Arctic Surface Water. Both of these water masses then exit the Kara Sea as deep and shallow countercurrents to the incoming Atlantic Water. The northernmost canyon allows some Atlantic Water to …

The Feeding Ecology And Trophic Role Of The Northern Pipefish, Syngnathus Fuscus, In A Lower Chesapeake Bay Seagrass Community, Clifford H. Ryer

Dissertations, Theses, and Masters Projects

The purpose of this study is to examine the feeding ecology and trophic role/importance of the northern pipefish, Syngnathus fuscus, in a lower Chesapeake Bay seagrass community.

The study incorporates; 1) examination of stomach contents in conjunction with prey abundance data, inorder to arrive at conclusions concerning the food preferences of S· fuscus, 2) determination of daily feeding periodicities and stomach evacuation parameters, thus allowing for the determination of a daily ration for S· fuscus, 3) examination of size relationships between S. fuscus and it's major prey species, 4) estimation of pipefish densities at the study site, and 5) examination …

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 …
