A Methodological Approach To Shifts In Drive Simuli., Peggy A. Keilman

Psychology ETDs

A study employing different and equal strengths of the hunger and thirst drive stimuli was conducted in an 8-ft. modified T-maze in an attempt to provide a somewhat more methodologically sound approach to the experimental analysis of the construct drive. The 11 rats used in the experiment underwent a pretraining phase that used a titration procedure to equate the strength of hunger and thirst for each animal by varying the conditions rather than the schedules of feeding and -watering the animals. The only restriction was that each animal's daily intake must sum to 24 (e.g., 13 g. food and 11 …

Spectroscopic Studies Of Complexes Of Rhodium (Iii) And Iridium (Iii), Dean H. W. Carstens

Chemistry and Chemical Biology ETDs

A comprehensive experimental and theoretical study of complex compounds of two d6 transition metal ions, rhodium(III) and iridium(III), was made to characterize the electronic transitions responsible for the various bands seen in the absorption and emission spectra and to determine the dependence of the energies of the excited states of a complex ion on the nature of the ligands and the central metal ion. All the complex compounds contained organic ligands—pyridine, 2,2’-bipyridine, or l,l0-phenanthroline—in the principal coordination sphere. Most also had halide ions bonded directly to the central ion. An ancillary study was made of 2,2’,2’’-terpyridine complexes of two d10 …

Analysis Of Heat Transfer In A Two-Layer Circular Cylinder:Constant Flux On Outer Surface And Zero Flux On Inner Surface, Mary Elena Franklin

Mathematics & Statistics ETDs

The one-dimensional time-dependent equation of heat conduction is solved analytically for an infinite two-layer circular cylinder whose core may be either hollow or solid. On the outer surface of the cylinder, which has no heat loss due to convection, a constant heat flux from an external source of heating is applied uniformly. The layers are in perfect thermal contact, and there is no heat loss at their interface. At the smaller radius of the inner layer is a perfect insulator so that the heat flux on the inner surface of the two-layer cylinder is zero. The temperature is uniform initially …

Where theta is an unknown parameter in Euclidean r space and {Zi}inf m is a sequence of independent, identically distributed random variables with E[Zi]=0 and E[Z 2 i]=1. This type of process will be termed a generalized autoregressive process in the sequel.

Effective Rates Of Evaporation And Chemical Properties Of The Precipitates., John Lincoln Rasho

Earth and Planetary Sciences ETDs

An experiment was designed to simulate the evaporation of sea water in the laboratory. The experiment was conducted isothermally at 35 1. Chlorinity, salinity, and density of the solution were determined at different stages of evaporation. Also the trace element contents of Sr, Rb, K, and Li of the precipitates were determined to study the possible changes, and the significance of these changes, in the concentration of these trace elements in solution at different stages of evaporation.

The results of this experiment and the work of previous investigators indicate that the rate of crystallization from sea water, at any given …

Fission Barriers And Transition-State Spectra For 232th, 234th, 238u, 240u, 242pu, And 244pu From 9t, Pf0 Reactions., James D. Cramer

Physics & Astronomy ETDs

Joliot and Curie’s discovery of artificially induced radio-activity in several nuclei by a-particle bombardment encouraged Fermi and his collaborators in 1934 to attempt similar experiments using neutron bombardment of various target elements/ Using natural uranium as a target material they discovered at least four radioactive products, assumed to be elements in the transuranium region. These experiments were repeated in 1937 by Meitner, Hahn and Strassman in Germany where they found that some of these radioactive elements produced by neutron bombardment of uranium had barium-like chemistry, and were assumed to be isotopes of radium. Further investigation proved that these products could …

Stratigraphic Analysis Of The Upper Permian And Lower Triassic Strata In Southern Utah, Charles Dennis Irwin Jr.

Earth and Planetary Sciences ETDs

Permian sedimentation in southwestern Utah was influenced by three principal depositional areas. These areas were the Oquirrh basin in north-central Utah, the Cordilleran geosyncline in eastern Nevada, and the Quemado-Cuchillo basin on the northern shelf of the Sonoran geosyncline in east-central Arizona and west-central New Mexico. Throughout Permian time, marine sediments and their well-developed beach and continental eolian sandstone equivalents were deposited within these basins and upon their surrounding shelves. Each of the three basins appear to have exerted their influence upon sedimentation during a discrete period of geologic time. Thus while one basin was sedimentationally active the other two …

A Calculation Of Photodetachment From Molecular Oxygen, Raymond Pollock Jr.

Physics & Astronomy ETDs

The problem of photodetachment from homonuclear diatomic mole­cules is treated theoretically, with the aim of providing a calcula­tion of photodetacbment from the molecular oxygen ion. Using a two­-center (spheroidal) coordinate system a one-electron model including direct coulomb, polarization, and approximate exchange interactions is developed, and formulas for scattering and photodetachment cross section are derived. Wave functions representing both bound and free electrons in the field of the neutral molecule are calculated numerically, using adjustable parameters in the exchange and polarization potentials to attain the proper binding energy. The photodetachment cross section is then computed from these wave functions, along with …
