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 Spinning Top, Aaron Jefferson Miles

Masters Theses

"Several mathematicians have solved the problems of motion of the top and gyroscope most completely, but none of them have considered in their solutions the effects of the supporting gimbal rings upon the motion or the effects of a variable rotor speed. It is the purpose of this paper to investigate the top equations by two well known methods; namely, by the method of Lagrange and by the method of Jacobi; considering in both the dynamics of the gimbal rings and varying rotor speed"--Introduction, page 3.

Age Relationships Of Ore Deposits Of Southwestern Montana (A Microscopic Study), Charles R. Trueworthy

Bachelors Theses and Reports, 1928 - 1970

Although considerable work has been undertaken by some prominent geologists, the best known of which is that of Paul Billingsley and J. A. Grimes', in investigating the ore deposits of the Boulder Batholith and surrounding area, there has not been any complete microscopic investigation of these deposits, as a whole, published in the literature. With this in mind it was suggested to the writer by Professor Paul A. Schafer, of the Montana School of Mines, that a microscopic study of the ores of this region would be a worthwhile geologic problem.

It was thought that the mineral association and the …

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.

A New Crinoid Slab, A Bit Of Mississipian Sea Bottom, Erwin Hinckley Barbour

Bulletin of the University of Nebraska State Museum

Crinoids are popularly known as stone-lilies, featherstars, and sea-lilies. The word lily is a misnomer, and many, misled by the name and by the lily-like form, associate crinoids with the plant kingdom. The name, feather-star, seems explicit for it refers to the feathery arms surrounding the cup or calyx, and expresses relationship to the starfishes and their kind. The cup is attached to a stem, and the stem is anchored to the ocean floor by so-called roots, which are really hold-fasts, or anchors. These features may be seen in the diagram at the end.

The Giant Beaver, Castoroides, And The Common Beaver, Castor, In Nebraska, Erwin Hinckley Barbour

Bulletin of the University of Nebraska State Museum

Respecting the giant beaver, Castoroides, in Nebraska, four occurrences can be reported. Of rodents in general the dawn. was in the early Eocene, at which time there were in existence certain squirrel-like members of the order. Rodents are a persistent group, and are among the smallest, most distinctive, most numerous and widely distributed orders of terrestrial mammals. No other order boasts of so many species, the number being between nine hundred and one thousand. In spite of wide divergencies and modifications adapting them to various modes of life, such as climbing, burrowing, swimming, flying, leaping, and running, there is remarkable …

The Musk-Oxen Of Nebraska, Erwin Hinckley Barbour

Bulletin of the University of Nebraska State Museum

The remains of no less than eight fossil musk-oxen are already known in Nebraska, of which one is preserved in the Museum at Hastings, Nebraska, and seven in the State Museum at Lincoln. This is a large number to be recorded in anyone state. As late as 1891 authors wrote that but two examples of musk-oxen were known in the United States, one from Kentucky, and one from Arkansas, if, indeed, they be valid species. Now that pioneer days are well behind this commonwealth, and that there is a growing sentiment for exploration and proper display of the State's resources, …

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 Preliminary Study Of The Separation Of The Copper Sulfides From Sphalerite And The Effect Of Certain Reagents On Some Of The Pure Copper Minerals In Synthetic Mixtures, Gailen T. Vandel

Bachelors Theses and Reports, 1928 - 1970

The problem of separating the copper sulfide minerals from sphalerite, in copper - zinc ores, has been a difficult one. This is largely due to the lack of adequate research and the small amount of data obtainable on the behavior of copper and zinc sulfide minerals in flotation circuits.

The Geology And Petrography Of A Portion Of Marlboro And Brattleboro Townships, Windham County, Vermont, Elizabeth Putnam Richards

Honors Papers

Location and area. The territory covered in this report is a roughly rectangular area of about fifty square miles. It is situated partly in Marlboro and partly in Brattleboro township, in Windham county, southeastern Vermont. It runs from 42° 50' to 42° 55' north latitude and from 72° 37' to 72° 47' west longitude. Geologically the region is a part of the Green Mountains while physiographically the area is in the New England Upland section.

Statement of the Problem and Methods. The origin, history and correlation of the country rock of the region is the particular problem with which this …

Geology And Acid Intrusions Of Marlboro Township, Vermont, Stanley Gordon Elder

Honors Papers

It is the aim of this paper to examine the mineralization resulting from the intrusion of acid dikes and veins into the schists of Marlboro township, Vermont, and to give a brief account of the geology of the area.

The problem of mineralization in southern Vermont is one which has been treated very slightly and is one which is deserving of more study than it has received. This problem results from the presence of numerous acid igneous masses in all the formation of the region. Petrographic research in the igneous intrusions was done partially with the hope that the study …

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 …

The Conservation Of Nebraska's Water Resources, G. E. Condra

George E. Condra Publications

Oxygen is the first immediate necessity of life and water is second. Both directly and indirectly and more than soil, water is our most basic resource. It is the universal solvent and without it there would be no life, and, of course, no agriculture and industry.
