Limnology Of Carbonate – Bicarbonate Lakes In Nebraska, D. B. Mccarraher

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

The relation between chemical, physical and biological indices was examined in 1,640 sandhill lakes during the years of 1954 to 1963. Sandhill lakes are formed by either (1) wind deflation basins and closed drainages or (2) exposed ground water table basins. Topography of the 20,000 square mile sandhill region is primarily stabilized dune sand interspersed with wet meadows and pine - cedar - oak river drainage systems. Two-thirds of the area is dune sandhills and one-third occupied by basins, valleys and lakes.

All of the lakes are comparatively shallow, the deepest lake being Blue Lake with 13.8 feet. The average …

Modules Over Commutative Rings, William G. Leavitt

Department of Mathematics: Faculty Publications

The following is another short proof of the fact that for a commutative ring with unit R, any finitely based R-module is "dimensional" in the sense that all of its bases have the same number of elements.

THEOREM. Let R be a commutative ring with unit. If M is a unitary R-module with a basis of n elements, then all bases of M contain exactly n elements.

Separation Of Optical Isomers By Solvent Extraction, George Truett Mccloud

Masters Theses

The purpose of this research was to develop a solvent extraction method to resolve optical isomers. Earlier work²⁵ done in this laboratory has indicated that partial resolution had been obtained by using D(+)-diisopropyl tartrate and water as the immiscible solvent system. Further work done by the author indicates that this method can be used to partially resolve racemic modifications. Before this method is discussed in detail, a summary of the known methods of resolution should be presented.

Angular Distributions Of Conversion Electrons From Oriented Ce137M Nuclei, Richard B. Frankel, D. A. Shirley, N. J. Stone

Physics

The angular distributions of K- and of (L+M)-conversion electrons from oriented Ce^137m nuclei were observed. Precise simultaneous intensity measurements of conversion electrons and γ rays from the same sample provided an accurate, direct determination of the particle parameters b₂ associated with the 255-keV isomeric transition in Ce¹³⁷. The K-electron result, b₂=1.061 (18), is in excellent agreement with a theoretical prediction based on a "point nucleus" model. Techniques and parameters in this experiment, the first of its kind, are discussed. A more careful determination of the temperature dependence of …

Crystal Field Splitting In Rare Earth Chelates, Walter George Perkins

Chemistry and Chemical Biology ETDs

Investigations of ligand field effects in the spectra of trisdibenzoyl­methide, trisbenzoylacetonate, and trisacetylacctonatc chelates of trivalent ytterbium and thulium are reported. Chelate absorption and luminescence spectra corresponding to intra-4f electronic transitions exhibit line split­tings similar in magnitude to the crystal field splitting observed in the spectra of inorganic complexes of the rare earth ions.

Absorption spectra of carbon tetrachloride solutions of all the che­lates studied were measured in the visible and near infrared regions. Each ytterbium chelate exhibits an absorption band at 9800A, consisting of three well-resolved peaks. Thulium intra-4f absorption bands appear at 4700A, 6800A, 8000A, 12000A, and 17000A. …

Observation Of Autoionization Levels In He By Positive Ion Bombardment, M. Eugene Rudd

M. Eugene Rudd Publications

Certain highly excited energy levels in helium have been observed optically and by inelastic electron scattering, and have been calculated theoretically. Reported here is the observation of these levels by the measurement of the energy spectrum of electrons emitted after bombardment with protons and hydrogen molecular ions. Some of the states show up clearly by this method which are weak or absent in the other techniques. Berry has previously observed autoionization of helium by this method, but his measurements lacked the resolution necessary to identify the states.

Water Yields In Utah Developing A State Water Plan, Jay M. Bagley, Roland W. Jeppson, Cleve H. Milligan

Reports

Need and Importance of Study

Utah's problems of water use and water supply are becoming increasingly important. They are also becoming increasingly complex as competition for our water resources becomes more keen among various types of uses. In the formulation of plans for sound and efficient use of water it is essential to know the characteristics of occurrence and use of water supplies so that requirements can be balanced most effectively and economically against supply. This ordinarily requires basic hydrologic data to determine relations among climate, water losses, and water yield from watersheds.

Such data are often unavailable - especially …

Investigations Of Neutron Collimators And Detector Systems Used In A Neutron-Capture Internal-Conversion Apparatus, William Charles Johnston

Masters Theses

Preface

During the past six decades considerable effort has been devoted to investigating and explaining the phenomena associated with the atomic nucleus. However, many important features of the nucleus still are not understood. Among these are such fundamental aspects as the structural composition of the nucleus, the nature of the forces between nucleons, and several of the basic processes that occur among the nuclear constituents. The goal of nuclear physics is to construct a unified theory which is able to explain all nuclear phenomena.

The experimentalist contributes toward this objective by gathering and classifying extensive amounts of experimental data in …

The Atmospheric Neutron Spectrum At High Altitudes, Michael Sydor

Physics & Astronomy ETDs

A measurement of neutron flux in the range 30 -130 Mev at altitudes of 10, 670 feet and 100,000 feet was performed with a directionally sensitive proton recoil detector. The detector consisted of two counters of scintillator plastic which measured dE/dx and energy of proton recoils originating in a third plastic scintillator. Charged particles were eliminated by a guard counter. Energy calibration was performed with charged cosmic ray particles; efficiency and angular sensitivity were calculated. The angular response was checked at 10,670 feet, where a reasonable angular distribution of cosmic ray neutrons could be assumed.

Four balloon flights to 100,000 …

Studies Of Tetrakis (Pyridine Base) Nickel (Ii) Perchlorate And Bisperchloratotetrakis (Pyridine Base) Nickel (Ii) Complexes, Lawrence Edward Moore

Doctoral Dissertations

The stereochemistry of nickel (II) compounds has been one of the most active and controversial fields of research in inorganic chemistry during the last 10 years. The multitude of colorful nickel compounds has intrigued chemists for a much longer time, but only in relatively recent years have such tools as visible and infrared absorptiometry, group theory and quantum mechanics, magnetic measurements, x-ray studies, and conductance measurements been brought to bear effectively to unravel the questions on stereochemistry in metal complexes.

Evaluation Of Methods Used In The Determination Of Stability Constants Of The Thallium (Iii)-Chloride System At Twenty-Five Degrees, Nelson Kent Dalley

Theses and Dissertations

The difficulties encountered in the determination of equilibrium constants in systems with small, not directly rneasureable free ligand concentrations are discussed. These difficulties are illustrated using the determination of the formation constants of the Tl(III)-Cl- system as a specific example. Four methods are used and evaluated in this study. They are (1) the corresponding solutions method, (2) the method of Fronaeus, (3) the solubility of AgCl in Tl(III) solution method and (4) the method of Hugus. A discussion and derivation of each of these methods is given. The first three methods given and free ligand concentration data from which formation …

Green's Relations And Dimension In Abstract Semi-Groups, George F. Hampton

Doctoral Dissertations

This thesis originated in an effort to find an efficient algorithm for the construction of finite inverse semigroups of small order. At one stage in trying to devise such a scheme, an attempt was made to construct an inverse semigroup by adjoining two non-idempotent elements to a semi-lattice in such a way that each of them would be D-equivalent to a pair of distinct D-equivalent idempotents. It was noticed taht such adjunction yielded an inverse semigroup only when the elements of the pari were incomparable in the partial ordering of the semilattice, and only when, for each positive integar n, …
