The Application Of Stress-Strain Analysis In Routine Control, Richard L. Memmer Dec 1970

The Application Of Stress-Strain Analysis In Routine Control, Richard L. Memmer

Paper Engineering Senior Theses

Many of the empirical strength tests used for determining end use performance of a paper sheet do not give a true indication of actual sheet properties and performance. The empirical tests of burst, tear, and folding endurance were made on eighteen paper samples of different grades of papers. The fundamental tests of tensile strength, elongation, and tensile energy absorption were also made on the same samples using a stress-strain tester. The fundamental tests were used in showing deficiencies and discrepancies in the empirical test values.

The discrepancies found indicated a need for increased fundamental testing to be use in predicting …


Turbidity Reductions By Enzymatic Hydrolysis, John Nowak Dec 1970

Turbidity Reductions By Enzymatic Hydrolysis, John Nowak

Paper Engineering Senior Theses

Turbidity has long been a problem to the paper industry. In the past, it has been mainly associated with secondary fiber mills, among others. However, with the recent increase in the price of virgin pulp, other mills are seriously considering secondary fiber as a substitute for virgin pulp. Therefore, turbidity may become a problem to a larger number of mills in the future. Turbidity arises when starch and a filler are sheared together in a system. It has been noted in the literature that hypochlorite-oxidized starch produces the greatest turbidity phenomenon.

This project assumed that the size of the starch …


The Effects Of Zeta Potential And Flocculant Molecular Chain Length On The Flocculation Of Fines, Kai F. Chiu Dec 1970

The Effects Of Zeta Potential And Flocculant Molecular Chain Length On The Flocculation Of Fines, Kai F. Chiu

Paper Engineering Senior Theses

The factors controlling floc formation and cohesion are discussed in terms of fiber entanglement, electrokinetic potential and fiber-polymer bridging. The methods of measurement of zeta potential and degree of flocculation are also considered. In addition, an experiment is designed to relate zeta potential, molecular weight of synthetic polymers and the degree of flocculation of fines.

It is found that fiber length is the most predominant factor controlling flocculation. The bridging effect of polymer comes next. The higher the molecular weight, the greater the degree of flocculation. The electrokinetic potential effect is only influential if simple electrolytes are used as flocculant …

Baseline Response Rate And The Effect Of A Stimulus Which Precedes Response-Independent Reinforcement, William M. Arnold Dec 1970

Baseline Response Rate And The Effect Of A Stimulus Which Precedes Response-Independent Reinforcement, William M. Arnold

Masters Theses

The relationship between baseline response rate and the effect of presenting a stimulus followed by response-independent reinforcement on baseline response rate was investigated in this study. Six pigeons were divided into two equal groups, one of which was conditioned to key peck on a VI-DRH schedule of food reinforcement, the other on a VI-DRL schedule of food reinforcement. Once responding had stabilized, a tone was introduced seven times during each session followed by a response-independent food reinforcement. The results indicated no change in the response rate of the VI-DRH group during the tone, and acceleration of responding during the tone …


The Reaction Of Substituted Benzenesulfonyl Azides With N,N-Diethylaminoprop-L-Yne, Frederick Warren Stanley Dec 1970

The Reaction Of Substituted Benzenesulfonyl Azides With N,N-Diethylaminoprop-L-Yne, Frederick Warren Stanley

Masters Theses

When aryl sulfonyl azides substituted with electron releasing groups reacted with N,N-diethylaminoprop-l-yne, the products were found to be l-substituted-4-methyl-5-diethylamino-l,2,3-triazoles. However, when the aryl substituents were electron withdrawing, the products were α-diazo amidines.

In solution, the triazoles were found to exist in equilibrium with an α-diazo tautomer. NMR provided a quantitative method of measuring the percentage of triazole and α-diazo amidine tautomer. The equilibrium was measured in various solvents.

The structures of the compounds were proven by chemical degradation to a N,N-diethyl-N'-arylsulfonyl-propion-amidine.

Masters Theses

Introduction

The purpose of this research endeavor was to determine the structures of the adducts of dichloroketene with diphenylfulvene and benzodiphenylfulvene. Structure elucidation was attempted by chemical degradation and nmr analysis.

The structures of the adducts of dichloroketene with cyclopentadiene1,2 and indene3,4 have been determined by previous workers. The influence of the exocyclic double bond on the mode of cycloaddition is unknown.
