Determination Of Energy Levels & Oscillator Strengths Of 2% Nd:Y2o3, Kung-Chuan Shao
Determination Of Energy Levels & Oscillator Strengths Of 2% Nd:Y2o3, Kung-Chuan Shao
Masters Theses & Specialist Projects
The absorption spectrum of 2% Nd:Y2O3 has been obtained at room termperature. It has been used to determine the crystalline energy levels.
Through counting the number of Stark components, degeneracies have been determined for oscillator strength calculations.
Overlapping absorption lines were analyzed into their components.
Oscillator strengths have been measured for those well-identified and analyzed transitions in the variable and near ultraviolet regions of the 2% Nd:Y2O3 absorption spectrum.

The Wavelength Dependence Of Herpes Simplex Viral Inactivation & Ultraviolet Enhanced Reactivation, Richard Detsch
The Wavelength Dependence Of Herpes Simplex Viral Inactivation & Ultraviolet Enhanced Reactivation, Richard Detsch
Masters Theses & Specialist Projects
The degrees of Ultraviolet Enhanced Reactivation (UVR) by mammalian cells of Heroes simplex virus inactivated by different wavelengths of far ultraviolet radiation were measure'. The wavelength dependence of UVR is presented for the wavelength region 238 nm to 297 nm. The shape of the UVR curve suggests that virus directed repair is less dependent on the wavelength of UV radiation than are cellular repair mechanisms. The wavelength dependence of Herpes simplex inactivation by far UV radiation is also presented. The shape of the virus inactivation curve suggests the involvement of both DNA and protein.
Magnetohydrodynamic Effects On The Growth Of Condensations In An Expanding Universe & The Formation Of Galaxies, Charles Evans
Magnetohydrodynamic Effects On The Growth Of Condensations In An Expanding Universe & The Formation Of Galaxies, Charles Evans
Masters Theses & Specialist Projects
We review the evidence for existence of a magnetic field of the galaxy and whatever evidence there is of an intergalactic magnetoionic medium. We then consider the magnetohydrodynamics (MHD) of such a medium. The formation of galaxies through purely gravitational means in an expanding universe is then reviewed. Next the role of magnetohydrodynamics in such a universe is analyzed for their effects on galaxy formation. Finally, the importance of MED behavior in the early universe is emphasized from physical considerations and from present day evidence. Appendices discuss isotropic cosmologies, magnetic fields in such a background, the detailed MHD perturbations, and …
An Analysis Of A New Partizan Game Using Combinatorial Techniques, James Snodgrass Iii
An Analysis Of A New Partizan Game Using Combinatorial Techniques, James Snodgrass Iii
Masters Theses & Specialist Projects
John Horton Conway's combinatorial game theory was applied to a new partizan game with a complete analysis as the result. Mathematical values were assigned to the countably infinite number of positions in the game. Direct computation of the first eight values and extension via the Principle of Mathematical Induction made the assignments possible.
Examination of these values (which repeat with period 2) shows that the game, played on a strip of squares, can be won by the first player if the strip is of odd length and can be won by the second player if the strip is of even …

Ua66/8/2 Climatological Summary: Barren River Area Development District, Wku Kentucky Climate Center, Glen Conner, Robert Sanderson, Robert Ashby, J. M. Phipps
WKU Archives Records
This document summarizes and analyzes the climate of the Barren River Area Development District, discusses seasonal variance and trends, and provides examples of the application of climatological data to climate related or induced problems. By using this document, planners can identify climate related problems, assess the probability of occurrence, develop recommended courses of action, and assist local governments in their planning efforts.
Ecotypic Differentiation Of Andropogon Virginicus L. In Relation To Strip Mine Spoil Banks, Valina Kay Hurt
Ecotypic Differentiation Of Andropogon Virginicus L. In Relation To Strip Mine Spoil Banks, Valina Kay Hurt
Masters Theses & Specialist Projects
Reciprocal plantings of populations of broomsedge, taken from an abandoned strip mine and from an abandoned farm plot in south central Kentucky, on strip mine spoil and abandoned field soil resulted in patterns of populations differentiation. Clonal plantings of populations from strip mine habitats and old field development appeared equal in height and biomass when grown on old field soils in both field trials and growth chamber studies. Populations when planted in strip mine soils in field trials and controlled growth experiments. Later flowering in strip mine populations may be a key to survival strategy in the harsh microclimates of …
Simulative Investigation Of The Detection Of Modes Of Luminosity Variation In Astrophysical Sources, James Collins
Simulative Investigation Of The Detection Of Modes Of Luminosity Variation In Astrophysical Sources, James Collins
Masters Theses & Specialist Projects
Five astronomical data analysis methods were evaluated, using computer simulation techniques, for minimum detection levels, periodicity detection, and parameter estimation sensitivities. The evaluation of these methods was accomplished using three basic waveforms with the addition of ten “random” noise samples from a Gaussian distribution of known parameters. The chi-square and t-test methods were evaluated in detecting low-amplitude variability and brightness level shifts. Results indicate both methods have a strong dependence on the estimation of the standard deviation (σ) where a 0.1 change in σ will affect detection rates by ten to twenty-five percent at the ninety-five percent confidence level. The …
The Effects Of Bridging Ligands On Anodic Stripping Voltammetric Analysis, Larry Beasley
The Effects Of Bridging Ligands On Anodic Stripping Voltammetric Analysis, Larry Beasley
Masters Theses & Specialist Projects
Anodic stripping voltammetry (ASV) is an electroanalytical method used in the determination of trace metals in solutions volumes of 20 milliliters or less. Generally, 10-6 M concentrations are routinely analyzed.
The analysis of Zn(II), Cd(II), and Cr(III) by ASV was Investigated, and the effects of introducing the bridging ligands, cyanide and thiocyanate into solutions of these metal ions was examined. These effects include a cathodic shift in the reduction potentials of the metals, and ASV signal changes ranging from small increases in peak currents to a total loss of peak-current signals, depending on the concentration of the ligand added.

Kinetic Studies Of Polymer-Bound Rhodium (I) Hydrogenation Catalyst, Nee-Yin Chou
Kinetic Studies Of Polymer-Bound Rhodium (I) Hydrogenation Catalyst, Nee-Yin Chou
Masters Theses & Specialist Projects
For many years, it has been customary to classify catalysts as homogeneous or heterogeneous. Generally, the former are more active and more selective. But the major disadvantage of the homogeneous catalysts is the need to separate the reaction products and to recover the catalyst, which is often somewhat more expensive than a "classical" heterogeneous catalyst. It has been considered, especially in the last ten years, that there might be advantages in chemically binding a homogeneous catalyst to a solid support.
Polymer-bound, anthranilic acid anchored rhodium (I) catalysts have been prepared. The rate of hydrogenation of cyclohexene has been studied quantitatively, …
