Preparation Of Phenylsulphur Chloride Tetrafluoride, Dennis T. Sauer

All Master's Theses

The reaction of C6H5SF3, CSF and C12 was studied under a variety of conditions. The reaction run in the presence of a trace of water yielded C6H5SO2F and C1C6H4SO2F. The reaction run in stainless steel at 170°C yielded an amber solid believed to be a polymer with the empirical formula C6H3.67SF2. Chlorination of a C6H5SF3-CSF mixture in monel at 220°C yielded a yellow liquid tentatively identified as a mixture of the new species C6H5SF4C1, FC6H4SF4C1 and C1C6H4SF4C1.

The Reaction Of Ethylenediamine With Cobalt (Ii) Perchlorate And Oxygen In Dilute Aqueous Solutions, Robert J. Karmy

All Master's Theses

Cobalt (II) perchlorate was reacted with ethylenediamine and molecular oxygen. Various mole ratios of ethylenediamine to cobalt (II) were oxygenated and studied by photometric, potentiometric, conductometric, magnetic susceptibility, freezing point depression, electron spin resonance and cobalt (II) extraction methods. The fact that the complex was brown in color, diamagnetic, contained ethylenediamine to cobalt to oxygen in a mole ratio of 4:2:1 was confirmed. The complex underwent elation to form a polymeric species with excess base. The complex could not be oxidized to a green paramagnetic complex by reacting it with sodium peroxydisulfate, potassium bromate, bromine or chlorine. Ammonia was added …

Theses and Dissertations

A new isothermal titration calorimeter has been designed to facilitate the study of heats of reaction and heats of solution at constant temperature. With this calorimeter, endothermic or exothermic processes can be studied at temperatures constant to ±0.0002°C. Heat effects are compensated by balancing the heat effect of the process taking place in the calorimeter against a variable heat and a constant cooling Peltier device. The calorimeter was tested by measuring the heat of ionization of water and the heat of dilution of aqueous HClO_4 solutions. For these systems heats were measured to an accuracy of ±0.02 calorie. Log K, …

Modified Dispersion Relations And Π Π Scattering, David J. George, Barbara N. Hale, Arnold Tubis

Physics Faculty Research & Creative Works

The ππ S-wave scattering-length predictions of Weinberg have been tested by using dispersion sum rules for the infinite-energy cross section. Reasonable agreement is obtained with the infinite-energy cross section (≈15 mb) estimated from the factorization theorem for the Pomeranchon Regge residues. Experimental phase-shift data of Gutay et al., Walker et al., and Baton et al. are used in estimating the dispersion integrals. The analysis seems to rule out an I = 0 S-wave scattering length ⪞0.4μ^-1.

An Instructional Method For Self-Administered Medications, Beryl Marx, Lorene Russell

Loma Linda University Electronic Theses, Dissertations & Projects

An experimental study was done to determine the effectiveness of an instructional method for older ambulatory patients taking prescribed self-administered medications. This method was developed to emphasize the physicians' specific orders, the purpose of medications, feedback of instruction and a plan for remembering and recording medications. The hypothesis tested was that a selected group of ambulatory patients age 60 and over with the instructional method would make significantly fewer errors than a similar control group with no instructions.

Sixty private patients from the Loma Linda University Hospital outpatient department were selected and randomly placed in the experimental and control groups. …

Economic Analysis Of Alternative Flood Control Measures, L. Douglas James, Thomas M. Rachford, James Ray Villines, Clyde R. Dempsey, James Norris Cline, Carlos Fix Miller

KWRRI Research Reports

Within the last few years, the growing realization that an effective flood control program must include non-structural measures (land use management and flood proofing) has resulted in Presidential Executive Order 11296 requiring Federal agencies to seek the optimum combination of structural and non-structural measures for flood control. The requirement has created a dilemma. No methodology is available for systematic evaluation of alternative combinations of structural and non-structural measures. Prospective procedures are too time consuming to be feasible under current financial and manpower limitations.

The only way out is to perform much of the planning process by digital computer. With this …

Facies Analysis; Fredericksburg Limestones; Callahan Divide, Texas, Andre Louis Boutte

LSU Historical Dissertations and Theses

During Fredericksburg (Early Cretaceous) time the entire Callahan Divide area of west-central Texas was the site of clayey, lime-mud accumulation in a normal-marine, shallow-shelf environment. Lateral homogeneity of the quiet-water environment was soon interrupted locally by the deposition of bioclastic lime-sands in a linear, highly agitated shoal-zone coinciding with a portion of the axis of a regional, positive, Paleozoic structural feature known as the Concho Arch. Localized shoal conditions persisted throughout most of Fredericksburg time and resulted in the deposition of a thick sequence of grainstones and packstones collectively referred to in this paper as the Callahan Complex. Numerous diastems …

Formation Of Etchable Tracks In Dielectrics, Robert Katz, E. J. Kobetich

Robert Katz Publications

It is proposed that etchable damage is produced in dielectrics by energetic charged particles when a critical dosage of ionization energy is deposited at a critical distance from the ion's path by secondary electrons. Within the critical cylinder, molecular fragments more soluble than the parent molecule are formed. The radius of the critical cylinder is taken to be approximately 20 Å, as is appropriate to the passage of the etchant along the track and the diffusion of reaction products back to the surface. At the critical radius the dosage approximates doses producing bulk damage under γ irradiation. The proposed criterion …

Width Of Heavy-Ion Tracks In Emulsion, E. J. Kobetich, Robert Katz

Robert Katz Publications

Profiles of the solid core of long, flat, ending tracks of heavy primary cosmic rays in Ilford G-5 emulsion have been measured by manually tracing their enlarged (3500X) photographic image. These measurements agree well in the ending 3000 μ of residual range (β <0.3) with a reformulated theory of track width based on computation of the spatial distribution of ionization energy. The measured core width in G-5 emulsion is the sum of the sensitized cylinder diameter, at which 6000 erg/cm³ of ionization energy is deposited by δ rays, and the diameter of a developed grain.

Possible Trivacancy Contribution To Ionic Conductivity, Robert Fuller, M.H. Reilly

Robert G. Fuller Publications

Fuller and Reilly [1], Fuller, Reilly, Marquardt and Wells [2], and Allnatt and Pantelis [3] have recently reported the results of measurements of the intrinsic electrical conductivity σ of RbCl, KCl and NaCl, respectively. All of these results showed an anomalous behavior of the log (σT) vs. T^-1 plot at temperatures near the melting points of the various crystals. It is the purpose of this note to discuss the suggestion [4] that the anomaly may be due to a trivacancy mechanism.

The plots of the log (σT) vs. T –1 were found to have too …

The Spectroscopic Constants Of The Ground Electronic State Of Hydrogen Molecular Ion, Bertle Daniel Hansen

Physics & Astronomy ETDs

ABSTRACT

An accurate theoretical determination of certain vibration rotation properties of the hydrogen molecular ion is made. Two different methods of analysis are used in the determination of these properties. First, an energy equation for diatomic molecules is

fitted directly to theoretical vibration and rotation eigenenergies of the ground electronic state of H+2 calculated by J.M. Peek. These eigenenergies include adiabatic corrections determined by w.Kolos. Second, a fixed-nucleus potential for the ground electronic state of H+2, calculated by J. M. Peek which did not include adiabatic corrections, is expanded in a power series in the neighborhood of the equilibrium internuclear …
