Kinetics And Mechanism Of Acylation Of Amines With 2-Naphthoyl Azide, Abraham L. Faburada

Dissertations

The reaction of 2-naphthoyl azide with primary and secondary amines in protic and aprotic solvents follows second-order kinetics. The effect of increasing solvent polarity is shown to increase the rate of reaction. For amines of similar basicity, the rate of reaction decreases with increasing steric hindrance on the amine. The changes in free energy and entropy of activation for n-butylamine and cyclohexylamine are in accord with steric requirements of amines. For amines of similar steric hindrance, the rate of reaction increases with increasing amine basicity. The mechanism of addition-elimination involving the formation of a tetrahedral intermediate is consistent with the …

A Test Of The Validity Of The Equipercentile Assumption: An Analysis Using A Data Base Of Title-I Eligible Students, Christine Applin Ameen

Dissertations

The Title I Evaluation and Reporting System (TIERS) consists of three basic evaluation models, the norm-referenced model, the control group model, and the regression model. The most widely used of these is the norm-referenced model. The equipercentile assumption, upon which this model is based, states that student groups, in the absence of Title I services, will maintain their percentile status over time. The validity of this assumption was tested using a data base of students who were eligible for Title I services but did not receive such services. The pre-and post-test reading and math scores of these students were aggregated …

Determination Of Organophosphorus Compounds By Hplc With Post-Column Photochemical Degradation Followed By The Formation Of Reduced Heieropolymolybdate, Stephen R. Priebe

Dissertations

A novel method for the determination of organophosphorus (OP) compounds by HPLC with post-column photochemical and chemical derivatization reactions has been developed. The OP compounds eluted from the column were photochemically degraded to orthophosphate by the use of a 450 W xenon lamp in conjunction with an auxiliary photodegradation reagent. The photodegradation reaction was studied extensively by means of batch irradiations with triethylphosphate as a model compound. The effects of the initial concentrations of triethylphosphate and ammonium peroxydisulfate, and of varying the pH of the reaction medium were determined. A survey of potential interferences was performed. Copper(II) ion was found …

Fractionation Of Multicomponent Mixtures By Staged Sequence Cyclic Process And Parametric Pumping, Charles Omotayo Kerobo

Dissertations

The continuous fractionation of multicomponent fluid mixtures has been experimentally and theoretically investigated by staged sequence cyclic process and parametric pumping operating in the direct thermal mode.

A multicolumn staged sequence cyclic process for the separation of solute mixtures was developed. The criteria necessary for the continuous fractionation of a system of n solutes with n+1 columns arranged in a series operated with n+1 cyclic variables is presented. The feasibility for practical application of this process was demonstrated by fractionating the model system, O-xylene-Anisole-n-heptane on silica gel. The separation was modeled by one column staged sequence experimental data and by …

Separation Of Proteins Via Ph Parametric Pumping With Electric Field, Helen Conway Hollein

Dissertations

A new semi-continuous parametric pumping process for the separation of protein mixtures has been developed, based on cyclic variation of pH and electric field. The model system used for this process consisted of a mixture of human serum albumin and human hemoglobin in contact with CM Sepharose cation exchanger. Experimental results show that the protein separation via the pH parapump with electric field is two to three times greater than the results which are obtained in batch chromatography or via either single-column or multi-column parapumps with cyclic variation of pH and ionic strength.

The separation in the new process depends …

Random Factors And Isofactors In Graphs And Digraphs, John Frederick Fink

Dissertations

A factor is a spanning sub(di)graph of a (di)graph. Factors that are generated by an algorithm that incorporates an element of randomness are often called random factors. An isofactor is essentially a factor G that is either empty or for which there exists a connected regular (di)graph H having a nontrivial G-factorization. Several topics, each concerning random factors or isofactors, are investigated in this dissertation. An historical introduction to these topics is given in Chapter I.

In Chapter II we define an antipath and say that a digraph is randomly antitraceable if every nonspanning antipath can be extended (at its …

Micellarly Catalyzed Reaction Of Substituted Benzohydroxamic Acids, Nop Utrapiromsuk

Dissertations

The rate constants for hydrolysis of ten derivatives of benzohydroxamic acid, namely, p-H, p-CH(,3), m-CH(,3), p-CH(,3)CH(,2), p-OCH(,3), p-NO(,2), p-Cl, and m-Cl, in 0.160 and 0.158 M HCl at 67.9-68.2(DEGREES)C without and with sodium 1-dodecanesulfonate were determined. There is a good linear correlation between log k(,w) and the Hammett substituent constants, (sigma), for all para and meta derivatives where k(,w) is the rate constant in the bulk aqeous phase. In the presence of micelles all the compounds, except the meta-nitro derivative, followed the standard pseudophase model of micellar catalysis. However, correlations of log k(,m) or log K/N, where k(,m) is the …

Modification Of Staff Behavior In A Mental Health Center, Craig Wendell Knapp

Dissertations

Behavioral research which has focused on improving employee behavior in business and human service organizations has pointed to an increasing need to develop simple, effective management tools which will maintain appropriate behavior changes. The purpose of the present study was to explore the controlling relationship between behavior and variables previously cited in the literature, and to develop a procedure to increase and maintain the amount of time which employees in a mental health center spent on priority activities defined by management.

Eleven male and female employees in four programs of a mental health center were exposed to conditions in which …

Remote Attitude Measurement Techniques, Frank John Elmer

Dissertations

A method has been developed for solving practical problems which can be expressed in terms of physical geometry. These problems often involve combining directional information observed by remotely located sensors reported in their own respective local coordinate systems. To transform this information into a common coordinate system, the attitude of the sensors must be measured with respect to this common coordinate system.

Physical geometry is a generalization of mathematical -geometry where objects define the endpoints of figures composed of ensembles of lines. A probabilistic approach has been taken which is based on the fundamental assumption that the objects can be …

An Experimental Study Of Multiple Steady States In A Photopolymerization Reactor, Chih-Ning Kuan

Dissertations

An experimental study of photosensitized free radical polymerization of styrene in both batch and continuous stirred tank reactors is presented. Each reactor was run under both adiabatic and isothermal conditions. Multiple steady states were investigated. Exact multiplicity and uniqueness criteria for the above systems were derived and a mathematical model developed to correlate the results.

For both adiabatic and isothermal continuous stirred tank reactors operating in the metastable state regions, the conversion and polymer molecular weight are greater than the corresponding lower steady state operations. At a given conversion level, the reaction time for both adiabatic and isothermal continuous stirred …

Ground-Water Flow Along The Total Shoreline Of Austin Lake And Its Environmental Contribution To Pollution Of The Lake, William Thomas Williams

Dissertations

The vertical direction of ground-water flow in Austin Lake was determined by placing minipiezometers along the entire shoreline at fifty randomly selected sites. Ground-water samples were taken at each site and the specific conductivity of the water samples was determined along with the chloride and phosphate content. The data were analyzed to determine if there were any relationships among water movement, chemical content, and the presence or absence of an onshore septic tank. The minipiezometer data show that the primary direction of water movement through the sediment-water interface is downward but may become reversed at localized regions as conditions vary. …
