Chemistry Of The Oxidant, Ferrate, Its Interaction With Specific Organics Found In Waste Water, Donald H. Williams, J. T. Riley

KWRRI Research Reports

It became obvious during this investigation that while much work has been done with ferrate (VI) chemistry, discrepancies existed in the literature and very little attention had been given possible engineering uses. This work attempted to fulfill these two needs in an exploratory manner.

The preparative techniques were reviewed and mechanical improvements made in one which allowed improved yields. Essentially what was done was to enlarge and improve the filtering technique of the product and use cooler temperatures throughout the preparation. This greatly shortened the time required. Then it was learned that the addition of ethyl alcohol to the final …

Solution Geochemistry Of The Water Of Limestone Terrains, John Thrailkill, David B. Beiter, Michael T. Osolnik, Roger H. Postley, William T. Mitchell, Leonard N. Plummer, James R. Riddell, Richard C. Worley, Robert D. Zwicker

KWRRI Research Reports

Limestone groundwater flows mainly in openings it has solutionally enlarged, thus an understanding of the water's state of saturation relative to calcite (the principal mineral component of limestone) is fundamental to an understanding of the nature and evolution of the limestone aquifer. This study investigated the Mammoth Cave-Sinkhole Plain (MCSP) and Cave Hollow (CH) aquifers in Kentucky, both in Missippian limestones.

Both aquifers were always undersaturated with calcite. Except for completely ventilated vadose flows (usually) and some vadose seepage (occasionally), all recharges sampled (sinking streams, vadose flows, and vadose seepage) were also undersaturated. The lack of saturation in the MCSP …

Trace Metal Analysis Of Barren River And Nolin River Reservoirs By Atomic Absorption Spectroscopy, Mary Jo Kennedy

Masters Theses & Specialist Projects

This research was part of a project underway at Barren River and Nolin River Reservoirs in south-central Kentucky. The research was partially supported by a grant through the Sport Fishing Institute, Washington, D.C.

The study reported herein was concerned with the analysis of trace metal concentrations in the two reservoirs. It is believed that the fish population may in part depend upon the trace metals present in the water. It is anticipated that the data presented in this paper will eventually be correlated with the biology studies of the reservoirs being carried out by the Department of Biology of Western …

Decay Of The (2S22P)2P Compound State In Helium By Two-Electron Emission, Paul Burrow, G.J. Schulz

Paul Burrow Publications

Compound states of atoms are known to decay by the emission of a single electron into many states lying at lower energies. Compound states associated with doubly excited states lie at energies above the ionization potential, and therefore the decay into an ion by the emission of two electrons is energetically possible. This paper presents evidence for such a two-electron decay in the case of the (2s²2p)^2p compound state of helium which derives from the (2s²)¹S atomic state.

The 1966 Eruption Of Izalco Volcano, El Salvador, William I. Rose, Richard E. Stoiber

Department of Geological and Mining Engineering and Sciences Publications

During October–November 1966 900,000 m³ of olivine basalt flowed from the flank of Izalco volcano, El Salvador. The total heat energy was approximately 10¹⁵ calories. No measurable changes in gravity occurred at stations on the active cone between August 1964 and August 1967. In the summit crater fumaroles have surface temperatures as high as 540°C. The cooling rate of these fumaroles was 18°C/yr before the eruption and 45°C/yr after. Yearly temperature cycles due to wet and dry seasons are superimposed on the general cooling trend. The rate of gas emission at four fumaroles in November 1967 was 86 …

Cyclization Studies Involving The Synthesis Of 5-Substituted-1-Naphthol, Clark Keelock Chow

Dissertations and Theses

The γ-o-substituted-phenylparaconic acids were prepared by a method patterned after that of Fuson. These paraconic acids were prepared in good yield. A re-investigation of the Perkin and Fittig methods of preparing γ-phenylisocrotonic acid was carried out without success.

The synthesis of γ-o-halophenylisocrotonic acids by thermal, and catalyzed decarboxylation of γ-o-halophenylparaconic acid, have been carried out in good yield. An effective catalyst, optimum temperature and reaction period of decarboxylation of the γ-o-halophenylparaconic acids have been determined. Infrared absorptions have characterized the γ-o-halophenylisocrotonic acids formed to be in the stable trans form. …

Spectrophotometric System For Transient Observation Of Solids Under Pulsed Electron Irradiation, R.T. Williams, Robert Fuller, M.N. Kabler, V.H. Ritz

Robert G. Fuller Publications

THE purpose of this note is to describe a relatively simple apparatus for measuring the properties of transient optical absorption and emission bands in solids under pulsed irradiation. The equipment is presently being for the electron beam. The electron beam traverses a 28 cm air path between the exit window of the electron accelerator and the titanium Dewar window. The sample is mounted in vacuum on the Dewar cold finger approximately 3 cm behind the Dewar window. Under these conditions a single electron pulse will deposit 10¹⁷ eV/cm² in the sample. This generates an easily detected transient absorption …

High-Field Galvanomagnetic Properties Of Aual2, Auga2, And Auin2, J.T. Longo, P.A. Schroeder, David J. Sellmyer

David Sellmyer Publications

Measurements of the magnetoresistance and Hall voltage have been made in the high-field region on the metallic fluorite compounds AuAl₂, AuGa₂, and AuIn₂. The results have been compared with those expected from the nearly-free-electron (NFE) model. These compounds are uncompensated. The magnetoresistance measurements in principal planes and directions, with one exception, support the NFE model, but the dimensions of the two-dimensional areas of aperiodic open orbits show pronounced deviations. Hall-effect measurements for B in the 〈100〉 and 〈111〉 directions indicate significant departures of the real Fermi surface from the NFE model. A proposed empirical …

Molecular Orbital Study Of Internal Rotation, Mark S. Gordon

Mark S. Gordon

The CND0/2 molecular orbital method is used to predict and explain the barriers to internal rotation in a number of molecules. The observed 3: 2: 1 ratio of the barriers in ethane, methylamine, and methyl alcohol is approximately reproduced as are most trends in the barriers of fluoro-substituted propenes; however, the calculated trends for fluoro-substituted ethanes are incorrect. The barriers in H202, F202, N2H4, N2F4, and NH20H and the effect of geometry optimization on these barriers are also discussed. The major source of the barriers in the first group of molecules is predicted to be due primarily to nonbonded interactions …

A Fluorometric Study Of Carbamic Acids And Carbamates As An Explanation Of Carbon Dioxide Transport In The Blood, Gerald John Tiberio

Honors Theses

The original project was conceived during the summer of 1967 while Bruce Cassidy was a research fellow of the Maine Heart Association. It is through his efforts I became aware of the problem.

This research project was undertaken in order to determine the applicability of fluorometry as a means of studying the carbamate reaction of simple amino acids to model the physiological substrate hemoglobin.

Nmr Investigation Of Alkylated Diethylene - Triamine Chloro Complexes Of Trivalent Gold, Alan Robert Case

Honors Theses

The rate expression for the su~stitution of a ligand in a square planar complex was first introduced in 1953 by Taube and Rich (1). The present study was undertaken in the hope of gathering some evidence for this postulated steric hinderance by use of Nuclear Magnetic Resonance Spectra (NMR). Study was limited to one family of complexes, the alkylated diethylenetriamine chloro complexes of gold (III).

Radiolysis Of Saturated Aqueous Iodine Solutions, Gregg Alan Foster

Honors Theses

It is a well-known fact that water, when subjected to ionizing radiation such as x-ray or gamma radiation, undergoes a decomposition. The generally accepted decomposition, although complex, may be represented by (1): It is also accepted that "when dilate solutions are irradiated, practically all the energy absorbed is deposited in water molecules and the observed chemical changes are brought about indirectly via the molecular and, particularly, the radical products. Direct action due to energy deposited in the solute is generally unimportant in dilute solutions (i.e at solute concentration below about 0.1M)” (3). Realizing that iodine is an excellent radical scavenger …

Energy Calculations For The 1Εg+, 1Δg, And 3Εg- Electronic States Of The Oxygen Molecule Using A Tangent Spheres Approach, Donald Francis Durocher

Honors Theses

J. W. Linnett has proposed in his book, The Electronic Structure of Molecules (l), an approach to molecular orbital theory which he calls the double-quartet approach. The double-quartet, or d-q approach in a molecule with a completed octet, states that electrons of each spin set assume, or try to assume a tetrahedral array around their 'mother atom'. In the case of molecular oxygen, there are three d-q figures representing the molecule in its ground and 1∑+g , 2∆g, states. This representation is shown in Figure 1. Henry A. Bent, at the University of Minnesota, has proposed that the electrons in …

Qualitative Thermodynamic Study Of Linkage Isomerism In Palladium (Ii) Complexes, Walter Michael Gantenbein

Honors Theses

The purpose of this research was to investigate linkage isomerism in dithiocyanatobistriphenylarsinepalladium (II), dithiocyanato-2,2'­bipyridinepalladium (II), and thiocyanatotetraethyldiethylenetriammine­palladium (II) thiocyanate. Studies of linkage isomerism in these compounds were made in the pure solid state using a Differential Scanning Calorimeter. The instrumental data was supplemented with visual observations of the isomerization.

Synthesis Of Silicon Compounds For Use In (P -> D) Pi-Bond Studies, Mark Thomas Messe

Honors Theses

A new compound, (CH3CH2)2 NCH2Si (CH3)3 (I), was prepared. Attempts at synthesis of Ø-N (CH3) – CH2Si (CH3)3 (II) failed while synthesis of CH30 – CH2Si (CH3)3 (III) gave approximately 85 percent product. Difficulty was incurred in the purification of III, probably because the reactants were not sufficiently dry. Compound I was only slightly miscible in CD2=S-CD3 in dimethylsulfoxide-D6. The soluble portion showed no exchange of the methylene hydrogens in I by deuterium from the solvent although some decomposition might have occured. The apparent complete absence of an exchange reaction suggests that even in the presence of the electronegative nitrogen, …

Theses and Dissertations

Earlier work in these laboratories on the heterotricyclic system 2,6-dioxa-10-azatricyclo[5.2.1.04,10]-decane, formed from 1,4-diketones and 2-amino-1,3-propanediols by a product-water-azeotroping procedure, was extended with the synthesis of analogous compounds, e.g., the 1,4,7-triethyl-, 1,7-dimethyl-4-isopropyl-1,7-diethyl-4-isopropyl-, 1,7-dimethyl-3- and 4-phenyl- compounds. The 1,7-dimethyl heterotricycle, the kinetically-controlled product, was accompanied by the thermodynamically-controlled product, 2-(2,5-dimethyl-1-pyrryl)-1,3-propanediol. The 1,7-diethyl heterotricycle was also accompanied by the isomeric pyrrole as were the 1,7-dimethyl-3- and 4-phenyl compounds. A scheme postulating a common intermediate is presented. The interesting analogous compounds, 1,7-dimethyl-2-oxa-6-thia-10-azatricyclo[5.2.1.04,10]decane, 1,4,7-trimethyl-2,6-dioxa-11-azatricyclo[5.3.1.04,11]undecane and 11-hydroxymethyl- and 11-methyl-9,13-dioxa-14- azatetracyclo[6.5.1.02,7 011,14]tetradeca-2,4,6-triene were also prepared. The syntheses in good yields of a considerable number of moderately to …

Late Cenozoic Geomorphic History Of Lee Canyon, Spring Mountains, Nevada, John Henry Gucwa

UNLV Theses, Dissertations, Professional Papers, and Capstones

Located in the west central portion of Clark County, Nevada, the Spring Mountain Range borders the western edge of the Las Vegas Valley. Within the mountain range, a fault block, there are several canyons whose geomorphic history is closely related to the geomorphic history of the major alluvial fans which flank the mountains. Lee Canyon, which is the study area is one of these canyons. In Lee Canyon is preserved a complex canyon fill which has been subjected to several periods of down-cutting and valley-widening. The details of the canyon's geomorphic history recorded by filling and fill removal has not …

Electrogeneration Of Molybdate Ion, Michael John Milano

Honors Theses

The electrogeneration of molybdate ion (MoO4-2) for possible use in a coulometric determination of thorium or lead has been investigated. Constant current electrolyses were used to study the oxidation of molybdenum to molybdate. It was found that molybdate can be generated in 1N HCl with from 96 to 100% efficiency. The current efficiency for molybdate generation in less acidic media could not be determined accurately. Coulometric titrations of known amounts of thorium with electrogenerated molybdate have been carried out. The endpoints, which were determined amperometrically, were found to be inexact and reproducible to only ± 5%. Coulometric titrations of lead …

Synthesis Of Benzyl-Beta-D Alcohol For Use In Studies Of Photolytic Solvolysis Reactions, John Crest Anes

Honors Theses

This project proposes a means for determining whether certain photochemical solvolysis reactions proceed by an SN1 or SN2 type mechanism. The method uses optically active substrates to determine whether the displacement reaction occurs with racemization or retention of configuration. This paper deals with the synthesis of optically active benzyl-α-d alcohol from which various appropriate substrates required for the study can be prepared. Benzaldehyde---d is first prepared by the Stephens reduction of benzonitrile using stannous chloride and deuterium chloride. The optically active alcohol is then prepared by the reduction of thebenzaldehyde-d with optically active isobornyloxymagnesium bromide.
