A Study Of The Effects Of The Chloride Ion On The Lead-Silver Anodes And On The Lead Tenor Of The Zinc Deposit In Zinc Electrolysis, William A. Mitchell

Bachelors Theses and Reports, 1928 - 1970

The electrolyte used in the commercial production of electrolytic zinc from zinc sulphate solutions contains small amounts of impurities each of which has its own effects upon the process. Impurities such as antimony, cobalt, nickel, and iron tend to lower the current efficiency while other impurities such as chlorine, fluorine, and nitrates tend to increase the corrosion of the lead anodes and thereby increase the lead tenor of the zinc deposit.

The Precipitation Of Calcium Tungstate From Sodium Tungstate Solution, Martin E. Messner

Bachelors Theses and Reports, 1928 - 1970

In view of the great need for tungsten in the present industrial world it is necessary that all known tungsten sourves be utilized to the greatest possible extent. Scheelite ores promise to be an increasingly important source of tungsten, inasmuch as the discovery of vast new deposits has been made and known deposits of high grade ores have practically been depleted.

The Effect Of Manganese On The Age Hardening Of Aluminum-Copper Alloys, Keith P. Burgess

Bachelors Theses and Reports, 1928 - 1970

It is known that age-hardening occurs in alloys of the solid solution type containing a hardening constituent, of a metal or metallic compound which is more soluble in the solvent phase at higher tempertures than at lower temperatures.

A Study Of The Beneficiation Of Low-Grade Domestic Chromite, Darrell Edward Bodie

Bachelors Theses and Reports, 1928 - 1970

Chromite, a strategic mineral, is being consumed in ever increasing quantities in the United States today. Although the United States imports practically all of the chromite that is being consumed, it is gradually becoming necessary to exploit the low-grade deposits that are located within the United States, and also the low-grade deposits of Canada.

A Petrographic Analysis Of The Basal Member Of The Kootenai Formation, Frank E. Coupal

Bachelors Theses and Reports, 1928 - 1970

The basal member of the Kootenai formation in south­western Montana is typically a fine to medium-grained "salt and pepper" sandstone and chert-pebble conglomerate. The section between Delpine, Montana, and Melrose, Montana, generally thickens and markedly coarsens to the West.

The Benefication Of A Low-Grade, Montana Scheelite Ore, Walter G. Parker

Bachelors Theses and Reports, 1928 - 1970

The increasing importance of tungsten as an industrial metal and the recent discoveries of extensive deposits of low-grade tungsten ores in Montana led to the investigation which is reported in this paper. The purpose of this investigation was to determine if a saleable concentrate could be obtained from one of these low-grade, Montana scheelite ores.

Oil Shales In Montana, Richard N. Miller

Bachelors Theses and Reports, 1928 - 1970

Montana has long been known to have very large resources of coal and oil, and undetermined amounts of oil shale. The reserves of coal and oil have been proven, in part, and have been produced commercially, but not much is known about the extent and apparent value of the oil shales. Under present .conditions, and according to standards set by the United States Bureau of Mines, the shales are not of commercial value. They are, however, a potentially valuable mineral resource, and portions of them will possibly be utilized, although not in the near future.

Commercial Fertilizers For Winter Wheat In Relation To The Properties Of Nebraska Soils, R. A. Olson, H. F. Rhoades

Nebraska Agricultural Experiment Station: Historical Research Bulletins

It is the purpose of this bulletin to report the investigations that have been made correlating soil properties and fertilization practices with yields of winter wheat. Since the success or failure of fertilization practices is so dependent on specific soil conditions, an attempt has been made here to further characterize the major soils of the different sections of the state which are devoted to wheat production and to analyze fertilizer practices and results in relation to the soil properties determined. The data are summarized for the four sections of the state designated as southeastern, east-south-central, west-south-central and western Nebraska. These …

A Study Of Petroleum Resources, Production And Consumption In The United States And Foreign Countries In Their Relation To Our National Welfare And Security, Ann Frazier

Student Scholarship

This document, submitted by Ann Frazier in 1953, presents a comprehensive study of petroleum resources, production, and consumption within the United States and foreign countries, specifically examining their relationship to national welfare and security. The research highlights that while the United States was the world's leading consumer and producer at the time, accounting for over half of global oil production and roughly sixty percent of consumption, its domestic reserves were a waning asset that could not be renewed. The author challenges the alarmist view of imminent exhaustion by distinguishing between proved reserves and total resources, noting that vast quantities of …

A Petrographic And Chemical Study Of The Bevier Coal Seam, Philip John Clarke

Masters Theses

"Samples of coal were taken at three inch intervals vertically down the Bevier seam at three localities in Macon and Randolph Counties. Channel samples were collected at the three localities. All samples were analyzed for ash content, total sulphur content, crucible swelling number, and volatile content. The channel samples were analyzed for "pyritic" sulphur, “sulphate" sulphur, and "organic" sulphur. Thin sections of the samples were used in an estimation of anthraxylon and attritus contents.

In all the samples studied, volatile content of the coal seemed to be related to the ash content and the sulphur content. Crucible swelling number also …

Wind Erosion Control—I, D J. Fleay

Journal of the Department of Agriculture, Western Australia, Series 3

Desserts have been formed in some parts of the world by the action of wind on once productive soils. This could happen to the light land areas of Western Australia if we do not profit by the lessons of the past and manage these soils with great care.

The Effect Of Cross-Linkage On Internal Diffusion In Dowex-50 Ion Exchange Resin, John Paul Peterson Jr.

University of the Pacific Theses and Dissertations

As far back as the time of Aristotle sand filters were used to purify water. However it was not until the time of Thompson and Way (1848), two English agricultural chemists, that the idea of actual exchange of ions was proposed. Ion exchange has been investigated extensively, resulting in applications to softening of water, purification of sugar, separation of compounds, recovery of metals, many pharmaceutical separations and many others.

It has been proposed that the internal diffusion should be related to the internal structure of the ion exchange resin. The object of this research was to measure the internal diffusion …

A Study Of Immiscibility In The Carbonates From The Metamorphic Rocks Of Southeastern Vermont, Ralph D. Cotter

Masters Theses

"This problem is an attempt to correlate grade of metamorphism (normally assumed to be temperature dependent) with the shape and dimensions of a solid miscibility gap. Such a correlation might permit mapping of a continuously variable function of metamorphism. The system, calcite and dolomite-ankerite, was chosen for study because of its relative simplicity. Samples of quartz-carbonate granulite were collected from the Waits River formation in southeastern Vermont through a range of metamorphic grades. Refractive index, "molecular" volume, manganese content, and density were determined for the carbonates of four of these samples. These values are plotted on a compositional diagram to …

Sunrise And Sunset Tables Times For Jan.-Feb., 1953

Journal of the Department of Agriculture, Western Australia, Series 3

Times of sunrise and sunset for every fifth day, are given for a number of towns throughout the State. Times for a town not on the list may be estimated if its position in relation to one or more of the listed towns is known. The times given for sunrise are those of the first appearance of the top edge of the sun over a true horizon; those for sunset give the time of the sun's disappearance below a true horizon. Situation in a valley would make the sun appear to rise later, and on a hill it would appear …

Soil Conservation Service - Basis Of Co-Operation, G H. Burvill

Journal of the Department of Agriculture, Western Australia, Series 3

The Soil Conservation Service has been established as provided in the Soil Conservation Act, 1945. To carry out its objectives will require the co-operation with it of individual farmers and landholders.
