The Catalytic Action Of Neutral Salts : The Effect Of Normal Alkali Sulphates On Alkali Acid Sulphates In The Ketonic Splitting Of Ethyl Acetoacetate, Elbridge Alvah Goodhue
The Catalytic Action Of Neutral Salts : The Effect Of Normal Alkali Sulphates On Alkali Acid Sulphates In The Ketonic Splitting Of Ethyl Acetoacetate, Elbridge Alvah Goodhue
Masters Theses
"The catalytic effect of neutral salts has been investigated for numerous reactions and various theories propounded to account for their action. In this work the action of normal potassium and sodium sulphates on solutions of the corresponding acid salt has been investigated for two concentrations of the latter at three different temperatures. An attempt has been made to account for the observed actions"--Introduction, page 1.
A Study Of The Iodine Content Of Representative Missouri Waters, Edmond Carl Hunze
A Study Of The Iodine Content Of Representative Missouri Waters, Edmond Carl Hunze
Masters Theses
"Investigations have shown that the iodine content of natural waters bears a direct relationship to the goiter incidence of a given region. A number of the states have analysed [sic] their water for this constituent in the development of this hypothesis. A search of the literature revealed the fact that with the exception of two instances the iodine content of Missouri water had not been determined. Since in certain regions of Missouri there is quite a prevalence of goiter, it was deemed important to determine the iodine content of Missouri waters. It was believed that such information would be a …
The System: Calcium Oxalate - Sulphuric Acid, Joseph Maple Wilson
The System: Calcium Oxalate - Sulphuric Acid, Joseph Maple Wilson
Masters Theses
"The manufacture of oxalic acid includes as one of the steps in the process, the conversion of calcium oxalate to the desired oxalic acid by treatment with sulphuric acid, and the subsequent crystalization [sic] of the oxalic acid from the solution of it thus made. This investigation has dealt with this conversion step, with regard to the various factors affecting it. The effect of time, acid concentration, temperature, volume of solution, solubility of reaction products, and possible compound formation have all been considered, and from the information thus gained the conclusion has been drawn"--Introduction, page 1.
The Solubility Of Solid Paraffin In The Lower Molecular Weight Hydrocarbons, Paul Weber
The Solubility Of Solid Paraffin In The Lower Molecular Weight Hydrocarbons, Paul Weber
Masters Theses
"In the process of oil refining, a certain fraction of distillate from the crude oil composes the so-called wax distillate fraction from which is obtained the various lubricating oils. But the presence of the waxes and solid paraffins in these oils is very undesirable as they possess no lubricating qualities. Consequently, they must be removed from this wax distillate before the oil can be marketed"--Introduction, page 1.

The Influence Of Religion Upon The Works Of Man, Bernice Marie Williams
The Influence Of Religion Upon The Works Of Man, Bernice Marie Williams
All Theses
The unity of any human race out of which grows the brotherhood of man, forms the first great moral basis of Altruism. No people can sucessfully accomplish any phase of work without involving religion in its aims, moralities and religion then the principal means by which one can modify men into whatever one likes provided that one is given time enough in which to do it. Yet nothing is perhaps more openly questioned today than the social power of religion, it is not any purpose fully the science of religion, but we must know something about the real nature or …

Some Philosophical Implications Of Behaviorism., Harold Wayland Tribble
Some Philosophical Implications Of Behaviorism., Harold Wayland Tribble
Electronic Theses and Dissertations
Psychology is the middle ground between philosophy and science. Philosophy deals with the interpretation of facts, with, a view to determining their ultimate cause. It is the search for knowledge of general principles--elements, powers, causes and laws--as explaining facts and existences. Science is systematized knowledge of facts, laws and proximate causes, gained and verified by exact observation. Science is the effort to show how laws operate, and how certain facts affect other facts. Philosophy seeks to show why laws operate as they do, and to discern what is the first fact. Science deals with the sequence of events and effects …
Religious Experience In The Light Of Current Psychology., Elwyn Judson Trueblood 1896-1963
Religious Experience In The Light Of Current Psychology., Elwyn Judson Trueblood 1896-1963
Electronic Theses and Dissertations
Psychology is receiving a new emphasis in the modern age. The subject of human consciousness, always fascinating, is now claiming our attention as never before. When we endeavor to link psychology with religion, the charm is greatly increased; for then we are dealing with two themes, rather than one, in which mankind has an abiding interest -- the human consciousness and the human soul. Thus, the psychology of religion has grown to be one of the most popular studies of our generation. Indeed, an eminent authority in this field ventures the opinion that the theoretical as well as the practical …
The Influence Of A High And Low Vitamin Content In Nutrition., Ruth Lovelace
The Influence Of A High And Low Vitamin Content In Nutrition., Ruth Lovelace
Electronic Theses and Dissertations
In the bulk of experiments on animal feeding the Albino Rat has served as the experimental animal. It has been proved that any diet which brings about satisfactory growth in white rats will also cause a young child to grow satisfactorily. Therefore, much attention is given to the breeding of such rats for experimental and scientific use. In the earlier stages of experimental work it was found that a diet which contained sufficient protein material and which yielded the proper number of calories because of the fat, sugar, and starch present, was a satisfactory diet. Later investigations showed that animals …
The Education Of The Natural Man : A Study In The Political Philosophy Of J. J. Rousseau., Esther E. Mason
The Education Of The Natural Man : A Study In The Political Philosophy Of J. J. Rousseau., Esther E. Mason
Electronic Theses and Dissertations
In these, the opening words of Emile, Rousseau admits us to a knowledge of one of the principles of his thought. Everything is good, he thinks, as it comes from the hand of God. It becomes bad through the interference of man with the work of nature. We might assume, then, that the interference is bad, and that man was better, more virtuous, before he was interfered with, or educated. And as a matter of fact, Rousseau found some such answer to the problem when it first presented itself to him. In Emile he finds another and more practical solution, …
The Renaissance Paradox In Spenser., Juretta V. Bamber 1898-1981
The Renaissance Paradox In Spenser., Juretta V. Bamber 1898-1981
Electronic Theses and Dissertations
The complex phenomenon known as the Renaissance stimulated man with an insatiable curiosity in all things that had to do with human life and activity. The powerful searchlight of curiosity was especially turned on the ancient world – its learning, art, and literature – with a resultant diffusion of light so widespread that its influence is incalculable. In Italy, which in the fourteenth century saw the dawn of the Renaissance, “a glorious sumptuousness” of life prevailed. Ostentation, manifesting itself in brilliant dress, in beautiful homes, in wealth, and in magnificence of every kind, characterized the new movement. The Renaissance insisted …
The Preparation Of Derivatives Related To Novocain., Helen Peil
The Preparation Of Derivatives Related To Novocain., Helen Peil
Electronic Theses and Dissertations
The study of the relationship between chemical constitution and physiological effect embraces many very interesting problems which are, however, frequently difficult to solve. In the investigation of any drug the first step is to determine the principle to which the physiological effect is due, and then by analysis and synthesis assign the correct chemical constitution to this principle. When the chemical constitution is definitely known, other compounds of a similar structure may be prepared, and their physiological action compared with the original drug. By this means it is sometimes possible to prepare drugs which possess the principle desired in the …
A Study Of Certain Physical And Chemical Characteristics Of Flaxseed And Of Linseed Oil, With Especial Reference To Date Of Harvest, Leo F. Puhr
Electronic Theses and Dissertations
From the review of the foregoing literature on flax, it is evident that little work has ever been done on the chemical composition of flax. Most of the work on flax up to the present time has been confined to the diseases of flax, principally the securing of varieties that are resistant to wilt. In an attempt to secure information in regard to the factors affecting the physical characteristics and chemical composition of flaxseed the following work has been done in this experiment: 1. The effect of time of harvesting upon physical characteristics of the seed. 2. The relation of …
A Study In The Metabolism Of The Adult Honey Bee, M. D. Farrar
A Study In The Metabolism Of The Adult Honey Bee, M. D. Farrar
Electronic Theses and Dissertations
The study of metabolism in the higher forms of life has been carried on for many year and much has been found out that has been of great importance in understanding the way things live and grow. It has been only in the last few years that attention has been given to this phase of the work in insects. The extensive work that has been carried on concerning metabolism in men and animals is the basis for the more recent researches on the lower forms including the microorganisms. Before this work could be carried out on the small forms it …

A Study Of High School And College Grades, Ivy Bernice Wilkinson
University of the Pacific Theses and Dissertations
The task I have set myself is one to which my interest has been led by a varied experience in high school teaching followed by several years teaching in college where our high school product is largely disposed of. In all that experience the giving of grades was a bugbear, a necessary evil apparently, and it occurred to me that if those grades had or could be made to have some value beyond the moment, sone directive or prognostic value, they might lose their 111-reputation in the minds of both pupil and teacher. With this thought in mind I interviewed …
