Reactions Between The Stannous And Arsenate Ions In Silicic Acid Gels, Willard Merle Farr

University of the Pacific Theses and Dissertations

Observation of crystal growths resulting from the chemical interaction of stannous chloride and sodium arsenate in silicic acid gels revealed the following very interesting fact. Gels identical in every respect except acidity, contained crystal growths varying greatly in appearance.

The purpose of this investigation was, therefore, to allow stannous and arsenate ion to combine in a series of accurately prepared gels, identical in all respects except the acid content, and to observe the effect upon crystal growth of: (1) varying the acid concentration; and (2) varying the kind of acid

A Bibliography Of The Theory Of Relativity, Ruth E. Richardson

University of the Pacific Theses and Dissertations

This thesis, a Bibliography of Relativity, has begun with a very meager knowledge of the amount of literature which has been written on the subject of relativity either s explanation or commentary. The project was to 11at all the books and periodical articles written on or about the subject Relativity which are on file in the libraries of the College of the Pacific, University of California and stanford up to and including the year 1920.

A Preliminary Study Of Electrical Conductivity In Silicic Acid Gels, Rudolph C. Ferguson

University of the Pacific Theses and Dissertations

In this project the author has attempted to determine the specific conductance of a gel of known composition; the changes, if any, of conductance in a gel as it sets; and the changes in conductance due to the diffusing of an electrolyte through the gel.

The Construction Of Conic Sections By Means Of Pascal's And Brianchon's Theorems, Benjamin Lee Welker Jr.

University of the Pacific Theses and Dissertations

The discovery of conic sections was made by Menaechmus (375-325 B.C.) an associate of Plato and a pupil of Eudoxus. This discovery, in the course of only a century, raised geometry to the loftiest height which it was destined to reach during antiquity.
