A Study Of The Efficiency Of Certain Starch-Cationic Resin Complexes, William E. Hellman

Paper Engineering Senior Theses

An attempt is made herein to compare the efficiency of commercially available cationic starches and those prepared in the laboratory using a pearl corn starch and different cationic resins. The efficiency of each is determined through evaluation of the resulting wet-web strength and dry strength tests. Results show that cationic starches can be prepared in the mill and comparable strengths are obtained with their use.

It has long been known that cellulose developes a negative charge from the carboxyl groups when dispersed in water. The same effect is found when starch is diluted in water. Wet end addition of starch …

Peracetic Acid Oxidation Of Lignin Model Compounds, Ron Mckelvey

Paper Engineering Senior Theses

Peracetic acid is being used to a limited extent as a bleaching agent for newsprint (1), and to a lesser extent, as a pulping agent, at least at the laboratory level (2). Haas, Schoch, and Ströle (3) report that peracetic acid is an excellent reagent for the preparation of holocellulose from wood. Ogait (4) also found that bleached cellulose could be obtained in 60 to 65% yield from wood and straw by the reaction of peracetic acid at 60 to 80°C. Haney, Martin and Sherk (5), and Poljac (6) have patented methods of oxidizing lignin in wood by peracetic acid. …

Improvement Of Heat Stability Of Paper Made From Sulfite And Kraft Pulps, Robert Perry Lynn

Paper Engineering Senior Theses

Paper made from bleached sulphite and sulphate pulps and then treated with sodium alginate and antimony resin solutions show far less physical and chemical degradation with heat than these same papers when not treated with these solutions. Sodium alginate and antimony resins solutions appear to inhibit degradation up to 175C for 45 minutes but are not effective when the papers are heated to 210 C for 45 minutes. The paper made with bleached sulphate pulp and saturated with sodium alginate solution showed an appreciable increase in folding strength when heated at 175C for 45 minutes, which is most unusual.

The Effect Of Drying Conditions On The Surface Properties Of A Commercial Coating, Lowell Henry Livingston

Paper Engineering Senior Theses

The air temperatures and velocities were varied in the tunnel dryer of a commercial coater to determine the effects on the coated surface. Laboratory drawdowns were also made using the same coating color and basestock only dried under different conditions. The coated sheets were then tested for IGT, Dennison wax pick, K&N ink receptivity, Smoothness, Scheid and Gloss to determine any relationships between drying rate and suface properties.

The Effect Of The Distance From The Size Press To The First Drier On Sheet Properties, Hugh K. Myers

Paper Engineering Senior Theses

It is the purpose of this thesis to attempt to evaluate the effect of the distance from the size press to the first drier on penetration and sheet properties. At a constant machine speed, this has the same effect as varying the dwell time of the starch on the sheet.

It has been found that an optimum distance or dwell time exists for strength properties, namely, breaking length and burst factor. The effect on air resistance and tear, however, is much greater than the effect on the above. Tear was found to increase 20% with dwell time. Air resistance experienced …

The Influence Of Low Viscosity Shear Of Pigments On Coated Papers Properties, John F. Schmitt

Paper Engineering Senior Theses

This paper covers the effect of shear by a sigma blade kneader on the optical properties of a given filler clay. The object was to produce a delaminated clay with an appropriate particle size distribution that would give improved optical properties over the original filler clay and possibly another conventional coating clay at the same particle size distribution as the sheared clay.

The Effects Of Variables On The Penetration And Pickup Of Starch Applied At The Size Press, Leonard O. Eklund

Paper Engineering Senior Theses

A literature research is presented concerning the pickup and penetration of starch at the size press. The literature research indicates there is very little quantitative results in this area. The objective of the experimental work is to determine the effect of starch temperature, sheet moisture, and machine speed on the penetration of starch into the sheet. The depth and quantity of penetration was obtained by using a spectrophotometer to determine the concentration of starch in microtomed samples.

The experimental results indicated that increased temperature of starch solutions and increased machine speeds increases penetration. Penetration also increases with increasing moisture content …

Echoes From The Field, Lois Vandenberg

Reading Horizons: A Journal of Literacy and Language Arts

The Portage Public Schools are now in the second year of a three-year program aimed at developing a balanced high school reading program. The first phase of the program began last year with a corrective reading program geared to those students whose reading ability was no more than three years below grade level and who were of average or above intelligence. The students selected for the program also showed some disparity between their verbal and non verbal Lorge-Thorndike scores. The corrective reading classes (fifteen to a section) met five days a week in a reading laboratory for intensive reading instruction.

Reading Horizons: A Journal of Literacy and Language Arts

Among college students from culturally deprived backgrounds the problem of communicating ideas in writing is indeed a real one. It hampers their progress in most of their academic courses and, in numerous cases, forces them to give up their goal of becoming college graduates—a decision which jeopardizes their chances of achieving their maximum potential.

Perception And The Administrator An Investigation Into The Perceptual Areas Of Difference Between The Various Levels Of An Organization, W. W. Mcintire

Masters Theses

Introduction

It is frequently voiced that most of the problems that occur in organizations are "people problems." There are the result of misunderstandings, differences of interpretation, and inadequate coordination of effort. This study is concerned with this problem area, but it should be made clear that no attempt will be made to investigate "problem people" in organizations. They may legitimately be considered as part of the problem area, however, investigation of them is beyond the realm and scope intended for this study.

Walsingham And Burghley: Factionalism In The Privy Council Under Elizabeth I, John W. Nott

Masters Theses

Introduction

The Elizabethan Age was the age of Shakespeare and Marlowe, when the English literacy renaissance attained a claims; the age of Drake, Hawkins, and Frobisher, when English sea power asserted its genius. It was also the age of great statesmen and political improvisation, for England was beginning to emerge as a world power. Headed by a queen whose primary claim to fame rested with her ability to inspire her people and manage her talented ministers, the island kingdom soon attained the status of a major nation. At Elizabeth's accession the government was in a state of decline but skillful …

Japanese - American Relations, 1941: A Preface To Pearl Harbor, Edward Gorn

Masters Theses

Preface

There are as many interpretations as there are writers on the positions of American foreign policy during the diplomatic negotiations with Japan in 1941. Historians supporting President Roosevelt's position tend to blame Japan's imperialism and expansionism as one of the main causes of the war. Revisionist historians like Charles Beard, Harry Elmer Barnes, and Charles Tansill, place the responsibility for Japan's declaration of war and surprise attack on the intransigent approach of the Roosevelt administration. To place the full burden of responsibility for the failure of negotiations on either Japan or the United States is to over-simplify the complex …

Effects Of Radiation Upon Consumption Of Alcohol As A Discriminated Fluid Stimulus In The Rat, Joseph A. Straka

Masters Theses

Introduction

In the recent history of psychology, considerable interest has arisen concerning the use of radiation (usually as a UCS fitted into a classical conditioning paradigm) to effect changes in behavior. Mechanisms by which radiation induces behavioral changes are obscure, and psychology, along with the disciplines of physiology and medicine, has been attempting to clarify variables in operation.

The study of drug {including alcohol) effects upon behavior has had a somewhat parallel development in the field of psychology in terms of its recency and the obscure nature of the variables operating upon resultant behavior.

These two areas of interest have …

The Effect Of Infrared Drying Rates On The Optical Properties Of Starch-Clay Coatings, Ray Ludwa

Paper Engineering Senior Theses

Experiments were conducted to determine the effects of varying rates of infrared drying on a starch-clay coated sheet, in-so-far as optical properties are concerned. Gloss may be increased by drying the coated side of the sheet, while brightness and opacity show decreases. There is an optimum rate of drying for a starch-clay coated sheet. Metal surfaces under a coated sheet being dried with infrared radiation materially effects the optical properties.
