Mechanistic Studies Of Alkylation Of Cobalt(I) By Cyclobutyl Derivatives, Hao Ku

Masters Theses

A study was initiated on the hypothesis, by Ugi and co-workers, that cyclopropyl, cyclobutyl, and cyclopentyl electrophiles might under go nucleophilic substitution reactions with retention of configuration.

The synthesis of benzocyclobutenol and 2-phenylcyclobutyl tosylate is described. The reactions of these tosylates with cobalt(I) "supernucleophiles" gave low yields of products which have not been purified sufficiently for assignment of stereochemistry.

Reaction of cyclopentyl tosylate and phenylethyl tosylate with the "supernucleophiles" cobaloxime(I) and cobalt(salen)(I) is discussed for the advance of future work.

The Intramolecular Torsional Potential And Dielectric Properties Of 2,3-Butanedione, Gevert H. Meyer

Masters Theses

Dipole moment measurements have been carried out on 2,3-butanedione in solution, pure liquid, and the vapor phase. A dipole moment of 1.03 ± .01 Debye was observed for dilute solutions of 2,3-butanedione in carbon tetrachloride. Pure liquid samples exhibit an anomalous dipole of 1.56 ± .01 Debye. The following results were obtained for vapor phase measurements: 1.04, 1.07, 1.08, 1.11, and 1.17 ± .01 Debye at 310.15, 350.15, 370.15, 431.70 and 472.10 ± .02°K respectively.

The acetyl torsional potential was characterized from the observed temperature dependence of dipole moment. This torsional mode was described by a two-parameter potential function: V(Ø) …

Mechanistic Studies Of Alkylation Of Cobalt(I) By Cyclopropyl Derivatives, Lailing Magdalene Soong

Masters Theses

A second order nucleophilic substitution reaction with retention of configuration is predicted by Ugi and co-workers if electrophiles such as cyclopropyl, cyclobutyl, or cyclopentyl derivatives undergo substitution under conditions where the S_N2 process is faster than the competing S_N1 process.

A synthesis of both cis and trans-7-chlorobicyclo [4.1.0] heptane from olefin and dichlorocarbene is described. The compound, bicyclo [4.1.0] heptylpyridine [bis(salicylaldehyde)ethylenediiminato] cobalt(III), which contains an alkylcobalt σ-bond, is obtained from the reaction of pyridine [bis(salicylaldehyde)ethylenediiminato] cobalt(I) and 7-chlorobicyclo [4.1.0] heptane. The great light sensitivity of this compound has prevented its isolation in purity sufficient for nmr …

Studies Of Acetylcholinesterase In Synaptosomes, Syed Abbas Rizvi

Masters Theses

Acetylcholinesterase from rat brain was studied in crude homogenates, partially purified enzyme fractions, and in synaptosomes, to observe modification of the enzyme as a consequence of the modification of the membrane containing it.

Sodium dodecyl sulfate decreases the absorbance due to particles in the homogenate. This change in absorbance was proportional to both the concentration of sodium dodecyl sulfate and the concentration of the particles. Further, sodium dodecyl sulfate caused sulfhydryl groups to appear in the crude homogenate and in partially purified enzyme fractions. Synaptosomal preparations did not give such results. At concentrations of sodium dodecyl sulfate sufficient to cause …

An Examination Of The Adaptive Random Search Technique., Mark William Heuckroth

Masters Theses

"Random search procedures have recently been successfully applied to the optimization o f a variety of chemical engineering problems, including optimization of chemical processes by flow sheet simulation. These procedures represent the independent variables as random variables described by probability distributions. The adaptive random search procedure centers the distribution for each variable about the best search point found and examines this region for a better point. Thus, this technique has the ability of continuously moving the search region toward the optimum, which is particularly advantageous in following constraints.

This study examines the efficiency of the adaptive random search technique as …

A Geochemical And Microscopic Study Of A Recently Discovered Deposit In Southern Illinois Fluorspar District., Prachon Chareonsri

Masters Theses

"A bedding-replacement fluorite deposit, discovered by recent drilling in the northeast part of the Cave in Rock district, southern Illinois, has been studied by a combination of geochemical, X-ray, and microscopic techniques. The dispersion pattern for trace zinc, lead, cadmium and copper concentrations in carbonate host rocks adjacent to the fluorspar deposit, determined by atomic absorption spectrophotometry, appears to hold only little hope in serving as an aid to exploration. Only cadmium anomalies appear closely related to the known fluorspar ore, and those values are not greatly above background.

Broad zinc and cadmium anomalies and a narrow lead anomaly are …

A Comparison Between Direct Waves And Head Waves In A Seismic Refraction Profile., Nelson Jose Aboud Garcia

Masters Theses

"The purpose of this investigation was to experimentally verify the theoretical prediction that the particle velocity of a head wave is the time integral of the particle velocity of a direct wave.

The procedure was to use small explosions in the field to generate direct waves and head waves in a surface layer of low compressional velocity overlying a higher velocity medium. The direct waves were distinguished by the ratio of frequencies and by the slopes in a time distance plot.

The result of comparing the particle velocity of the head waves with the integral of the particle velocity of …

A Method For Verifying The Kalman Conjecture., Charles Edward Connelly

Masters Theses

"The Kalman and Aizerman conjectures are of value because, if true, they allow the replacement of a nonlinear stability problem by an equivalent linear stability problem. However, the conjectures are not true in general. This thesis presents a method for verifying the Kalman conjecture. A theorem is also presented which extends the usefulness of the method and allows several very general results to be obtained. The method is based on an off-axis circle criterion of Cho and Narendra and a consideration of the curvature of the Nyquist locus of the transfer f unction. A table is included which summarizes the …

Performance Evaluation Of Linear Systems Using The Fast Fourier Transform., Larry Leonard Lamano

Masters Theses

"In order for a computer simulation of a communication system to yield useful and meaningful results, a method for determining system performance is often essential. The computer postprocessor, described in this thesis, allows accurate determination of the mean-square-error induced by the system being simulated and the noise power at any point in the system.

Measurements of the mean-square-error induced by a system due to amplitude distortion, phase distortion, and amplitude and phase distortion, along with measurements of the power in a Gaussian noise waveform are performed. The values obtained using simulation are compared to the corresponding theoretical values in order …

Reflected Surface Waves From A Vertical Discontinuity., Jesus Manuel Aboud

Masters Theses

"Surface waves generated in the field by small explosions were observed along lines parallel and perpendicular to a vertical discontinuity in a surface layer. Three types of wave particle motion were observed in waves incident on the discontinuity: retrograde, progressive, and shear (SH). Waves of the last two types were intense enough to observe a reflection, permitting calculation of reflection coefficients. The results demonstrate the feasibility of using reflection measurements to locate a discontinuity such as a fault zone"-- Abstract, p. ii

The Availability And Development Of An Automated Accounting System For Small Businesses., Margy Rice Beckmeyer

Image Detection In Signal Dependent Noise., Robert D. Laramore

Masters Theses

"This thesis deals with the detection of two-dimensional signals in the presence of noise, including signal dependent noise. The object to be detected and the background are assumed known a priori. A decision rule based on a likelihood ratio test is obtained and the associated probabilities of detection and false alarm are evaluated. This is done first in general terms, where neither the form of sampling nor the model used for noise is specified. Then results are obtained for three examples: Poisson noise, signal dependent Gaussian noise, and binomial noise. Finally, the degradation resulting from a point spread function is …

Ultrasonic Instrumentation And The Dynamic Evaluation Of Asphalt-Aggregate Mixtures., John Edward Hill

Masters Theses

"Ultrasonic probes have been constructed for use in the dynamic and nondestructive testing of asphaltic concrete specimens. The probe systems exhibited characteristics superior to the solitary ii use of their main components, the piezoelectric crystals. The probes have the advantages of the reduction of ringing time, the concentration of ultrasound in one direction, the elimination of "noise" due to unshielded connections and the increased durability of the probe system.

The probes constructed were used in a limited testing program. Compression and transverse wave velocities in the specimens tested were measured simultaneously. Sample conditions suitable for maximum wave velocity corresponded to …

Experimental Study Of Electron Density And Confinement Time In An Electrostatically-Plugged Cusp Device Using A Microwave Interferometer, Robert Louis Hayward

Masters Theses

"The average electron density and electron confinement time in an electrostatically plugged magnetic spindle cusp device are studied using a 20 GHz microwave interferometer. The results are compared with the predictions from approximate theoretical equations. With a magnetic induction in the point cusp of 5000 Gauss, a plasma is produced by injecting a 5 mA, 500 eV electron beam into hydrogen gas at 10^-5 Torr. The measured electron density is 2 x 10^-10 cm^-3 and the measured confinement time is 80 ysec, which agree to within a factor of two with values predicted by theory"--Abstract, page ii.
