Part I. The Stereochemistry Of Carbanions Formed By Base Catalyzed Decomposition Of Azoacetates Part Ii. Anomalous Decarbonylation Of 4 –Substituted Carboxylic Acids With Thionyl Chloride, Tai-Shun Lin
Dissertations
Introduction
Although the stereochemical capabilities of carbonium ions have been extensively investigated, the stereochemical fate of carbanions has been subjected relatively little to systematic scrutiny. The fact that only a limited number of clean-cut sources of carbanions are available has added difficulty to such investigations.
The stereochemical capabilities of carbanions has been extensively and thoroughly examined in recent years by Cram and coworkers. However, the carbanion carbon developed in the reactions employed was bonded in every case to an unsaturated (usually aromatic) group. No fully aliphatic carbanion has been subjected to such a stereochemical study.
The reaction of lead tetraacetate …

Theoretical And Experimental Evaluation Of Cardiac State Utilizing Indicator Dilution Methods For Nonuniform Ventricular Mixing, Stanley Myron Welland
Theoretical And Experimental Evaluation Of Cardiac State Utilizing Indicator Dilution Methods For Nonuniform Ventricular Mixing, Stanley Myron Welland
Dissertations
This research is directed toward the development and application of a new approach to the evaluation of cardiac work to diagnose cardiac state. A procedure has been developed for calculating the work performed on the fluid by the left ventricle during the heartbeat. The procedure involves the continuous direct measurement of ventricular fluid mixture temperature during and following the controlled injection, through a catheter, of a known volume of cold saline into the left ventricle. The measured mixture temperatures are used to calculate continuous ventricular volumes during the systolic and diastolic functions of the heartbeat. Plotting measured ventricular pressure versus …
On The Classification Of The Solution Space Of Linear Anisotropic Elasticity, Richard Clement Carman
On The Classification Of The Solution Space Of Linear Anisotropic Elasticity, Richard Clement Carman
Dissertations
A method is developed within the framework of Synge's function-space interpretation of problems in linear elasticity which allows the consideration of solutions to problems for anisotropic media in terms of the solutions of a corresponding isotropic problem and corresponding simpler anisotropic problems. The isotropic solution and simpler anisotropic solutions establish points in each of the statically and kinematically admissible spaces for the anisotropic problem. The established points are used to define sets of vectors in the statically and kinematically admissible spaces. The linear independence of these vectors can then be determined by a pair of criteria developed in this work. …
A Study Of The Dynamics Of Gas Adsorption In An Air Fluidized Bed, William Charles Zalewski
A Study Of The Dynamics Of Gas Adsorption In An Air Fluidized Bed, William Charles Zalewski
Dissertations
The dynamics of gas adsorption was studied in an air fluidized bed containing activated alumina particles. The adsorption studies made with a fixed bed and in the transition region between minimum fluidization velocity and 2.0 times minimum fluidization velocity, compliment work done at higher velocities. With adsorption, particle motion controlled the overall dynamics of the fluidized bed. A different approach in applying the two phase fluidization model was necessary to satisfactorily describe unsteady state adsorption in fluidized beds. Experimental and theoretical results were compared in frequency response plots to obtain a rigorous comparison. Good agreement was obtained for flow rates …
Non-Linear Analysis Of Electrocardiogram Tracings In Detection Of Occult Coronary Artery Disease, Joseph Robert Levitt
Non-Linear Analysis Of Electrocardiogram Tracings In Detection Of Occult Coronary Artery Disease, Joseph Robert Levitt
Dissertations
The general problem of identifying significant characteristics of a system by analyzing the properties of a signal emitted by that system is common to many disciplines, biological as well as physical. In general, achievement of a satisfactory solution depends on the capability of assigning membership of candidate signals to one of a number of mutually exclusive categories:
In this study, a new technique of processing the standard electrocardiograms from human subjects has been developed. This technique employs a set of non-linear transformations which enable the assignment of electrocardiograms into one of two Mutually exclusive categories. The first category is that …
Dynamic Stress Concentrations About An Epilliptical Discontinuity In An Elastic Solid, Kenneth Roy Schroll
Dynamic Stress Concentrations About An Epilliptical Discontinuity In An Elastic Solid, Kenneth Roy Schroll
Dissertations
The redistribution of dynamic stresses caused by the presence of an elliptical discontinuity in an infinite isotropic homogeneous elastic solid is examined. The solutions are obtained for the special cases of the rigid immovable inclusion and the vacuous cavity inclusion, and numerical results are presented.
The solutions to the wave equations in elliptical coordinates are expressed in series of the elliptical geometry eigenfunctions. Application of the boundary conditions, vanishing displacements for the rigid immovable inclusion and vanishing stresses for the cavity inclusion, yields in each case two infinite sets of linear algebraic equations for the expansion coefficients of the series …
Oscillations In Pulse Frequency Modulated Control Systems, Warren Joseph Guy
Oscillations In Pulse Frequency Modulated Control Systems, Warren Joseph Guy
Dissertations
This dissertation is concerned with oscillations and their stability which occur in a control system containing two nonlinearities, separated by linear elements. Specifically the nonlinearities are Integral Pulse Frequency Modulators and the linear elements are described by ordinary differential equations which are linear. The IPFM can be modelled by a quantizer with hysteresis and many other PFM laws are related to IPFM, thus the study applies to more than just IPFM alone.
Boundaries on the system parameters are identified within which free oscillation may be possible. These boundaries give sufficient conditions for stability and necessary conditions for instability. Also since …

Dimethyl Sulfoxide Oxydation Of Hydroxy-Steroids And Studies On The Oxidation Of The 5’–Hydroxy Group Of Nucleosides, Carmen V. Zenarosa
Dimethyl Sulfoxide Oxydation Of Hydroxy-Steroids And Studies On The Oxidation Of The 5’–Hydroxy Group Of Nucleosides, Carmen V. Zenarosa
Dissertations
Introduction
In our earlier work we demonstrated the usefulness of the acidcatalyzed reaction between N-(p -tolyl)diphenylketenimine (21) and dimethyl sulfoxide (DMSO) for the oxidation of secondary alcohols. This was exemplified by the oxidation of 2',3'-O-isopropylideneadenosine and other secondary alcohols.1 We have now extended this procedure to the oxidation of hydroxy-steroids.
Alkynylamines or ynamines can be written in two resonance forms: R-C≡C-N R'2 and R-C=C=NR'2. Because of the close similarity between the latter structure and the structure of a ketenimine (R2C=C=N-R') and the ability of sulfoxide-ketenimine to effect the oxidation of secondary alcohols, we …
Simulation Of Periodic Tank Reactors, Noshir Pirojshaw Mistry
Simulation Of Periodic Tank Reactors, Noshir Pirojshaw Mistry
Dissertations
Normally it is assumed that the steady state mode of operation is most desirable for the design of the chemical reactor system. However it appears that this assumption may not be correct in many cases.
In the present work disturbances of various types were externally created and forced on a system comprising an isothermal continuous stirred tank reactor. The effects of these purposefully created disturbances were investigated by mathematically modelling the system and simulating it on a digital computer.
The change in reactor performance, as defined by the percentage change in the production rate from the steady state value, can …
