A Study Of The Deposition Of Wax In A Wax Emulsion By Electricity, Howard Mcdonald

Bachelors’ Theses

The basis of this thesis resides in an experiment performed by Dr. J.R. Koch of Marquette University during the summer of 1931. Dr. Koch poured some liquid emulsion into an "H" tube and attached the electrodes to a source of DC current. A few days later he noticed the wax bad separated from the emulsion and had passed to the positive electrode leaving the solution surrounding the negative electrode clear.

Problem-Solving In Arithmetic, Eva M. Acker

Bachelors’ Theses

For a century arithmetic has been a popular subject in the elementary schools, and has consumed more time than any other subject. The war had an effect in reducing this time on arithmetic, largely due to the war-time emphasis on health, food production, back-of-the-line morale, and kindred subjects. More recently, school activities and playground work have come in for a reasonable share of the school time. The Twenty-ninth Yearbook recognizes the child as the center of interest, and the final criterion of all values being the effect any technique of teaching or any content of instruction has on the child. …

A Study Of An Objective Placement Examination For Sectioning College Physics Classes, John Milton Willson

Masters Theses

"For several years the Department of Physics of the Missouri School of Mines has practiced sectioning of its classes in general physics. The aim has been to segregate in one section the students of superior ability, giving them a course including both the fundamentals of physics and their applications in engineering. The remainder are given a course in fundamentals without placing so much stress upon the applications...Another criterion used to supplement the first-year grade record is the student's score on the Iowa Placement Examinations. The physics examination consists of two parts, the Training Series and the Aptitude Series. These examinations …

A Measurement Of The Extent Of The Color-Sensitive Areas Of The Retina And Of The Wavelengths Of Light Stimulating The Respective Receptor Mechanisms, Charles A. Rinde

University of the Pacific Theses and Dissertations

The interest of the writer was directed toward the phenomena of color vision in 1927 as a result of attending concurrently two courses in the University of California touching upon the subject, but treating it quite differently with results far from mutually consistent. Prof. R. S. Minor, in his course on physical optics, discussed color vision from the physicist’s standpoint, making use of the Young-Helmholtz theory; while Prof. G. M. Stratton gave the psychological treatment, based upon the Ladd-Franklin theory, as a part of his general psychology. Several of the more obviously points of conflict impressed the writer so strongly …

Theories Of Color And Color Vision, M. Regina Wallesch

Bachelors’ Theses

Theories of color have occupied the human mind since an early date even to the present. According to Professor Frank Allen there are from sixty to seventy different theories. Plato considered color to be due to flame-like particles projected from the pores of matter into the eye. Aristotle thought colors arose from various combinations of white and black.

Experimental And Observational Geometry, Albert D. Field

University of the Pacific Theses and Dissertations

Geometry has the distinction of being one of the oldest subjects given in the high-school.

Its subject-matter was formulated and organized by the Greeks into a fine system of thought before the time of Christ. Since leaving the hands of the Greeks, geometry has received only a few minor changes, and these largely in recent years.

Heretofore, the study of geometry has been made almost entirely dependent upon memory and reasoning. Geometricians have been slow in adopting the laboratory and observational methods.

This thesis has been written to encourage the student in his work of observing geometrical forms, and in …

Evidence Of Loess Man In Nebraska, Erwin Hinckley Barbour

Conservation and Survey Division: Faculty and Staff Publications

Unconsciously or otherwise an investigator is often influenced to see that which seems confirmatory rather than that which is contradictory to his conceptions and beliefs. But in conducting the search for evidence of human remains in the Pleistocene the writer has striven against this psychological tendency and has aimed to be severely critical and exact.

Report On The Progress Of The Nebraska State Geological Survey And The Morrill Geological Expedition Of 1901, Erwin Hinckley Barbour

Department of Earth and Atmospheric Sciences: Faculty Publications

IN spite of the phenomenal heat of the summer of 1901, which was of such intensity and duration that active work in the field was finally suspended, enough progress was made to justify the presentation of the matter to this society. It should be reported, first of all, that a request for funds, amounting to twelve hundred dollars, for publishing the first reports of the state geological survey, was presented to the Legislature, and was passed April 1, 1901, without comment or dissent. This may be recorded as the first sum voted by the state for the examination and publication …
