The Geology Of The Eldorado Mining District, Clark County, Nevada, Spenst M. Hansen

Doctoral Dissertations

The rocks of the Eldorado mining district, Clark County, Nevada, are of Precambrian, Tertiary and Quaternary age. Precambrian rocks include a heterogeneous series of gneisses and schists, younger garnetiferous granite gneiss and a youngest group of pegmatites. Paleozoic and Mesozoic rocks present in surrounding areas are absent in the district and Tertiary volcanics lie directly on the Pre- cambrian basement. Tertiary rocks consist of middle to late Tertiary flows and pyroclastic beds of andesite, basalt and rhyolite. These are assigned to three volcanic formations: the Patsy Mine volcanics; the Golden Door volcanics; and the Mount Davis volcanics. The Patsy Mine …

A Laboratory-Centered General Chemistry Course For College Freshmen, Alexander Vavoulis

University of the Pacific Theses and Dissertations

In order to give the laboratory-centered course a trial run and to compare it with a lecture-centered course it seemed necessary to the author that both courses should be taught and compared. The latter gave rise to the following hypotheses:

1. Students in a laboratory-centered general chemistry course show more favorable attitudes toward chemistry than do students in a lecture-centered course.
2. Students in a laboratory-centered course show as good a subject-matter mastery as students in a lecture-centered course.

Water Requirements For Waterfowl Areas Near The Great Salt Lake Parts V-Vi, J. E. Christainsen, Ming Chang Tsai, D. K. Kaushik, J. B. Law, J. W. Teeter

Reports

This report reviews activities on this project since the Progress Report, Part IV, June 1961.

The summer of 1961 has been one of the driest on record for Ogden Bay and Howard Slough Refuge. The extreme shortage of irrigation water has resulted in very little flow in the Howard Slough which originates from return flow. The available water from the Weber River for the Ogden Bay Refuge was also the lowest on record. The scarcity of water at these two refuges has resulted in increased salinity.

Most of the routine work on the project during the summer was done by …

Perfection Of The Lattice Of Dislocation-Free Silicon, Studied By The Lattice-Constant And Density Method, Martin E. Straumanis, Pierre Borgeaud, William Joseph James

Materials Science and Engineering Faculty Research & Creative Works

The lattice-constant and density method revealed that a high-purity silicon crystal free of dislocations has a perfect lattice without an excess of vacant sites or interstitials (n′=8.0000 4) within the limits of error, in agreement with the results obtained with the decoration method. The lattice constant of vacuum heated silicon powder of semiconductor purity was 5.43070±0.00004 A; that of the nonheat-treated powder was 5.43081 A at 25°C. The constants determined from crystal chips by the rotating crystal method were lower: between 5.43028-5.43048 A at 25°C. As the constants of each series of measurements could be reproduced very well (s=±0.00004 A), …

Angular Distribution Of Electrons In Extensive Air Showers, Don D. Laniewski

Physics & Astronomy ETDs

Electrons are the main products of an extensive air shower and comprise approximately 90% of the shower. Since these electrons are the most numerous particles near the axis of a large shower and are not easily detected, extensive air showers are most easily studied by means of the electronic component. Thus, whatever concern there may be about the nucleonic cascade of which the electron is an outgrowth, it is necessary first to understand the development of the electronic component and is lateral and angular distribution. Also, for the correct analysis of any experimental data, it is of particular importance to …

Content, Sequence, And Emphasis Of Arithmetical Concepts As Presented In Six Textbooks And An Analysis Of Student Errors In Fifth Grade Arithmetic, Lorenzo Groutage

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Arithmetic problems and the mastery of such problems play an important role in society as it exists today. The pressure from the public has been and is for better teaching of the basic skills. Public school teachers have often evaded this issue (2). For the past decade the emphasis has been "Why Johnny Can't Read," but it seems equally important, because of the relationship of reading and arithmetic, that the focus also center on the mathematical phase of educa­tion (8).

The Influence Of Soil Compaction Upon The Thermodynamics Of Soil Moisture, James E. Box Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The retention of water in soils is a very interesting subject. Soil-water research presents a great challenge to research workers. The challenge is broad in scope and extends from the field problems of large irrigation projects to the atomic scale of the solid-liquid interface.

If scientists are going to describe scientifically soil-water relations, they must ultimately utilize the instruments of science and the language of mathematics. To the end of the latter the mathematics of thermodynamics has been applied in these studies of water retention in soils.
