The Extraction Of Manganese From Manganese Flue Dust., John Raymond Moore
The Extraction Of Manganese From Manganese Flue Dust., John Raymond Moore
Bachelors Theses and Reports, 1928 - 1970
It is estimated that 90 to 95% of the world’s consumption of manganese is used in the steel industry in the form of either ferromanganese or spiegeleisen. The remainder is used in the form of either salts or oxides, chloride, dioxide and monoxide.
A Study Of The Effect Of Oxygen On The Rate Of Dissolution Of Gold In Cyanide Solutions., John A. Cook
A Study Of The Effect Of Oxygen On The Rate Of Dissolution Of Gold In Cyanide Solutions., John A. Cook
Bachelors Theses and Reports, 1928 - 1970
The accepted chemical reactions in the dissolution of gold by cyanide solutions require the presence of gold, cyanide, water, and oxygen. The importance of dissolved oxygen in cyanide solutions as a factor is recognized by those familiar with cyanidation. Manufacturers of cyanidation equipment realize the necessity of oxygen, as shown by the appliances they have developed which are attached to the agitators in order to saturate the cyanide solutions with air.
The Control Of The Grain Size Of Zinc, Oswald J. Wick
The Control Of The Grain Size Of Zinc, Oswald J. Wick
Bachelors Theses and Reports, 1928 - 1970
The use of zinc as a structural metal has been militated against by two of its properties, namely, its low tensile strength and its susceptibility to grain growth. The importance of these factors can be appreciated when it is realized that the tensile strength of coarsely crystalline cast zinc is 4,000 pounds per square inch, while finely crystalline cast zinc has a tensile strength of 12,000 pounds per square inch.
Contact Metamorphism In The Highlands, Frank Trask Jr.
Contact Metamorphism In The Highlands, Frank Trask Jr.
Bachelors Theses and Reports, 1928 - 1970
On the southern margin of the Boulder Batholith, about twenty miles south of Butte in the Highland Mountains, there are many miles of contact between the igneous and sedimentary rocks. As two kinds of igneous rocks and many different kinds of sedimentary rock are present, it is an excellent place for the study of contact metamorphism.
The Geology Of A Part Of The Bear River Range And Some Relationships That It Bears With The Rest Of The Range, Vic E. Peterson
The Geology Of A Part Of The Bear River Range And Some Relationships That It Bears With The Rest Of The Range, Vic E. Peterson
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The structure of the western three or four miles of the Bear River range east of Logan, Utah, has many times been alluded to in papers written locally on Cache Valley and the related ranges. There has not however, ever been, to the author's knowledge, an investigation made of this portion of the range for the express purpose of determining its exact structure. Although the area specifically covered by this present investigation is greatly inadequate to base the whole west range structure on, the author believes that the facts brought to light by the specific study of this area, added …
The Vitamin D And Provitamin D Content Of Some Varieties Of Utah Wheat, Harold M. Nielsen
The Vitamin D And Provitamin D Content Of Some Varieties Of Utah Wheat, Harold M. Nielsen
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Cereal grains were known to be notably deficient in the anti-rachitic principle even before the discovery of vitamin D. Clinicians had associated a type of rickets of infancy, characterized by an over-weight, flabby, bowlegged condition, with a diet consisting mainly of cereals. Mellanby (1) in 1921 concluded that this type of rickets is induced by overfeeding with carbohydrates. He also showed in the same report, however, that oatmeal, although it contains less carbohydrates than the other grains tested, possesses a special tendency toward rachitogenesis.
The Influence Of Ph On The Activity Of Trypsin And Papain (Caroid) As Measured By A Modification Of The Northrup Gravimetric Casein Method, Frank W. Dragan
The Influence Of Ph On The Activity Of Trypsin And Papain (Caroid) As Measured By A Modification Of The Northrup Gravimetric Casein Method, Frank W. Dragan
Bachelors’ Theses
Hydrogen ion concentrations have long been recognized as an essential factor in many biochemical processes.
The influence of hydrogen ion concentration upon enzyme activity has been of especial importance as proteolytic enzymes are rapidly gaining in use in various industries, principally the tanning industry.
Some Properties And Applications Of Symmetric Functions, Marie C. Kniewel
Some Properties And Applications Of Symmetric Functions, Marie C. Kniewel
Bachelors’ Theses
The word symmetry suggests that more fundamental aspect of all being, unity. In mathematics as in all other sciences, there is no going without having glimpsed something of that unity. Given even a glimpse, the wayfarer on the path toward mathematical truth, finds the traveling made, not easy, but more certain.
The Solution Of The Quartic Equation In One Variable, Jack W. Bril
The Solution Of The Quartic Equation In One Variable, Jack W. Bril
Bachelors’ Theses
The purpose of this thesis is to discuss two of the foremost solutions of the quartic equation---Descartes' method and Ferrari's method. Most of the ideas were garnered from books on the theory of equations. The historical material was obtained from histories of mathematics.
Geology And Ore Deposits Of The Golden Era And Goldfinch Mines, Argenta Mining District, Montana., Glenn C. Johnston
Geology And Ore Deposits Of The Golden Era And Goldfinch Mines, Argenta Mining District, Montana., Glenn C. Johnston
Bachelors Theses and Reports, 1928 - 1970
This report includes the results of geological investigation of a small area in the northern part of the Argenta mining district. Approximately two square miles were mapped. The underground working of the three mines only were accessible: the Goldfinch. Golden Era, and Mayday mines.
A Preliminary Study Of Montana Copper - Nickel Ore, J. Argall Mcallister
A Preliminary Study Of Montana Copper - Nickel Ore, J. Argall Mcallister
Bachelors Theses and Reports, 1928 - 1970
Deposits of sulfides, containing nickel and copper with associated platineferous minerals occur in the Stillwater Igneous Complex. This is a group of unusual igneous rocks situated in Stillwater and Sweetgrass counties in Montana.
The Effects Of Lime On The Amalgamation Of Gold., Rollien R. Wells
The Effects Of Lime On The Amalgamation Of Gold., Rollien R. Wells
Bachelors Theses and Reports, 1928 - 1970
An amalgam is an alloy of mercury with other metals, and amalgamation is the art of making or forming amalgams. In metallurgical language the word is limited to the means adopted for the recovery of gold and silver from their ores by the use of mercury.
Geology Of Some Gold Deposits Of Montana, Leo Edwin Efraimson
Geology Of Some Gold Deposits Of Montana, Leo Edwin Efraimson
Bachelors Theses and Reports, 1928 - 1970
Gold is one of the rarer metals in nature, and chemically it is one of the most inactive. Gold forms stable, natural compounds with few other elements, and only with metals.

A Method Of Changing Certain Infinite Series To New But Equivalent Series, Moneta Gunilla Johnson
Mathematics & Statistics ETDs
The purpose of this investigation is to prove that the sum of a series of variable terms of a certain type is equal to a constant plus the sum of another series of variable terms. As a result of this proof it may be hoped that certain series, which so far have not been summed, may be shown equal to a constant plus another series for which the sum is known.

As a basis of reference the assumptions and theorems of the Boole-Schröder system are given in full below. In general, the proofs of the theorems are not included, as they may be found in the treatise on the subject by these two men. However, in the case of a few of the theorems, new and original proofs were deemed to be of sufficient interest to be included here.
In the proofs which are included the following form has been used throughout. The page is divided into two columns, the logical steps of the proof appearing in the left column, and …
Note On The Greatest Integer Function, M. A. Basoco
Note On The Greatest Integer Function, M. A. Basoco
Department of Mathematics: Faculty Publications
In this note we wish to record certain finite sums involving the greatest integer function E(x), which seem to be of some interest. Hermite* has shown that the generating function for E(x) has the simple form, (1) xb ÷(1 -x)(1 -xa) = Σ(n)E[(n + a - b) ÷ a]xn, where a, b are positive integers. To him is due, likewise, the development (2) ) xb ÷(1 -x)(1 + xa) =Σ(n)E1[( …
