A Study Of The Sidereal Diurnal Variations Of Cosmic Rays Underground., Albert Brunsting
A Study Of The Sidereal Diurnal Variations Of Cosmic Rays Underground., Albert Brunsting
Physics & Astronomy ETDs
The sidereal diurnal variation of cosmic rays has been measured using underground (40 m.w.e.) meson telescopes located near Albuquerque, New Mexico (35.20°N, 106.41°w) and at Chacaltaya, Bolivia (16.31°s, 68.15°w). Each ofthe two locations has telescopes which scan the vertical and four inclined directions.
Two and three complete years were used for the telescopes at the Bolivia and New Mexico locations respectively. The average solar diurnal variations were calculated for each telescope for each month. Based on these monthly averages, the sidereal diurnal variations were computed. A correction was made in the analysis for any yearly modulation of the solar diunal …
Land Use Changes And Sharp-Tailed Grouse Breeding Behavior, Leonard H. Sisson
Land Use Changes And Sharp-Tailed Grouse Breeding Behavior, Leonard H. Sisson
Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts
The sharp-tailed grouse formerly inhabited much of the area which is now Nebraska. The sharp-tailed, along with its near relative, the greater prairie chicken, disappeared from parts of its former range which were put into intense cultivation. The 20,000 square mile area of the Sandhills were not suited to such cultivation and consequently is the remaining stronghold of the sharp-tailed in Nebraska. It is one of the more important sharp-tail ranges remaining in the United States.
With continuing decreases in suitable sharp-tail habitat throughout its former range in the United States, it is important to understand land use trends and …

Steady-State And Transient Currents In Organic Liquids By Injection From A Tunnel Cathode, Pavel Smejtek, David G. Onn, M. Silver
Physics Faculty Publications and Presentations
Experimental data are presented on the currents induced in organic liquids by injection from a tunnel cathode. The injection level was varied over a wide range resulting in almost no space‐charge limitation to almost complete space‐charge limitation. Results were different from that usually observed in solids, in that at low fields, the steady‐state current was proportional to V², while at high fields the current was proportional to V. By proper choice of electrode spacing and applied voltage, space‐charge‐limited current transients as low as 10⁻¹¹ A∕cm² and 5 sec transit times were observed. A smooth transition between the electrode‐limited and the …

A Study Of V(Iii) - V(Iv) And Ti(Iii) - Ti (Iv) Isotopic Exchange Reactions In Acid Solutions, Charles J. Orth
A Study Of V(Iii) - V(Iv) And Ti(Iii) - Ti (Iv) Isotopic Exchange Reactions In Acid Solutions, Charles J. Orth
Chemistry and Chemical Biology ETDs
The subject of this dissertation is primarily the mechanisms and kinetics ot V(III) - V(IV) and Ti(III) - Ti(IV) electron exchange reactions in homogeneous solutions. The electron exchange process is a form of oxidation-reduction or electron transfer reaction where there is no net chemical change, i.e., the concentrations of the chemical species remain unchanged. In such cases there is a continuous exchange of electrons between a reduced and an oxidized form of the same element, such as between Fe(II) - Fe(III), V(III) - V(IV) or Tl(I) - Tl(III). The first two pairs involve one-electron changes while the thallium pair involves …

Lattice Dynamics And Second-Order Raman Spectrum Of Naf, John R. Hardy, A. M. Karo, I. W. Morrison, C. T. Sennett, J. P. Russell
John R. Hardy Papers
The second-order Raman spectrum of NaF has been measured using an argon laser source. For a light beam incident along the [010] direction, polarized along the [001] direction, and viewed along the [100] direction, the scattered radiation is almost completely polarized. It is shown theoretically that it is possible to account for the polarization and the detailed shape of the observed spectrum within the experimental resolution using a Raman polarizability tensor whose second derivatives with respect to nuclear displacements depend only on the positions of first neighbors in the crystal, provided one uses the phonon frequencies derived from a deformation …

Multiple Charge States, Hyperfine Interactions, And Relaxation Processes Of Fe In 57Co-Doped Mgo, J. Chappert, Richard B. Frankel, A. Misetich, N. A. Blum
Physics
The Mössbauer spectra of cobalt-57-doped magnesium oxide have been studied between 1.3 and 550°K in external magnetic fields of up to 135 kOe for both single-crystal and polycrystalline samples. At room temperature and zero external magnetic field, the velocity spectrum is composed of three single lines, attributed to monovalent, divalent, and trivalent iron. In certain samples, for T2+ line undergoes a transition to a quadrupole doublet with a splitting ΔEQ=0.30±0.02 mm/sec, while in certain other samples, annealed differently, no doublet is observed down to 1.5°K. The first case is in quantitative agreement with a random-strain model …
A Shock Tube Study Of Recombination In The Lean Hydrogen-Oxygen Reaction Based On The Infrared Emission From Water Vapor, Larry S. Blair
A Shock Tube Study Of Recombination In The Lean Hydrogen-Oxygen Reaction Based On The Infrared Emission From Water Vapor, Larry S. Blair
Physics & Astronomy ETDs
ABSTRACT
Recombination in the hydrogen-oxygen reaction has been studied by monitoring the growth of infrared emission at 2.7 microns from water vapor as it is formed behind incident shock waves. Experiments were carried out in gas mixtures with hydrogen-to-oxygen ratios between 1.0 and 0.33 and temperatures between 1435° and 1868°K. Reactants were diluted with 92-98% argon. The validity of the transparent gas approximation (emission intensity proportional to (H20]) and the relationship between emission intensity and temperature were established by calibration experiments in which mixtures of water vapor and argon were shock-heated to temperatures between 1328° and 1982°K. Analysis of H20-emission …

Electrochemical Measurements In Molten Fluorides, Howard W. Jenkins
Doctoral Dissertations
The nickel (II) / nickel couple, contained in a boron nitrade compartment, was shown to be a useful reference electrode in fluoride melts. From emf measurements no nickel (II) / nickel concentration cells, the nickel (II) / nickel couple was shown to obey the Nernst equation in molten LiF-NaF-KF (46.5-11.5-42.0 mole per cent) and LiF-BeF2-ZrF4 (65.6-29.4-5.0 mole per cent). It was found that in some cases the reference electrode had a significant junction potential across the boron nitride wall.
Kinetics of the charge transfer reaction Ni(II) + 2e = Ni were investigated by the voltage-step method. Apparent …

Tb35: Alpine Soils On Saddleback Mountain, Maine, J. G. Bockheim, R. A. Struchtemeyer
Technical Bulletins
Alpine regions do exist in the Northeast, but are less extensive than in western United States and Alaska. Although the areal extent of alpine soils is not known in Maine, nearly 1.4 million acres of land are classified by the Soil Conservation Service as "mountainous." In Maine several mountains with subsidiary peaks greater than 4,000 ft in elevation support alpine zones, including Katahdin, Sugarloaf, Bigelow, North Brother, Saddleback, and Abraham.

Local Moment Formation And Resistivity Minima In Coal Alloys, G.R. Caskey, David J. Sellmyer
David Sellmyer Publications
Measurements of electrical resistivity, thermoelectric power, and magnetoresistance have been made from 1.4° to 300°K in alloys of 48%–57% cobalt in aluminum. At the equiatomic composition, CoAl has the CsCl structure. Resistance minima were observed in the vicinity of 30°K for cobalt concentrations between 50.4% and 51.5%. Below the resistance minima there is a temperature region where the dependence is approximately logarithmic before it saturates at about 1.4°K. The depth of the minima [ρ(1.4°K)– ρ( Tmin)] and the thermopower at 4.2°K both show rather sharp peaks as a function of concentration in the vicinity of 50.5% cobalt. The …
