The Measurement Of Mineral Electrode Potentials, John Charavelle Ingram Jan 1913

The Measurement Of Mineral Electrode Potentials, John Charavelle Ingram

Bachelors Theses

"The present investigation was undertaken with a view to consider the variables which tend to cause inaccuracy in the above mentioned measurements and as preliminary to a further study of the subject by the Missouri Bureau of Geology and Mines. The subject is one which, judging from the work of others and from my own experience, will require much more experimentation before results are obtained which are sufficiently reliable for the use of the economic geologist"--Introduction, page 3-4.

Relation Of Carbon Dioxide In Flue Gases To The Efficiency Of A Boiler, Richard A. Wagstaff, Philip A. Moore, William Ehlers, James Hopkins Jan 1913

Relation Of Carbon Dioxide In Flue Gases To The Efficiency Of A Boiler, Richard A. Wagstaff, Philip A. Moore, William Ehlers, James Hopkins

Bachelors Theses

"This thesis was undertaken to demonstrate the practical utility of measuring the efficiency of a Heine Boiler, installed in the Power Plant at the Missouri School of Mines, by the amount of CO₂ in the flue gases. The tests were made on a new boiler which had recently been installed in the Power Plant. The boiler and setting being new, the tests should show a high percentage of CO₂ in the flue gases and a high evaporative efficiency by the boiler"--page 3.

Volhard's Volumetric Method For Manganese, John A. Murphy Jan 1913

Volhard's Volumetric Method For Manganese, John A. Murphy

Bachelors Theses

"The purpose of this article and the data contained is an attempt to show how the percentage of manganese varies with different mounts of zinc salt present. It was also intended to determine the ratio of manganese to oxygen and zinc in the brown percipitate sic obtained upon the titration of manganese sulphate against a permanganate solution in the presence of varying quantities of zinc, but through an oversight the data is insufficient for this purpose"--Introduction, page 2.

A Series Of Tests On The Condensation Of Zinc Vapor To Metallic Zinc, Frank W. Cody, John W. Greene Jan 1913

A Series Of Tests On The Condensation Of Zinc Vapor To Metallic Zinc, Frank W. Cody, John W. Greene

Bachelors Theses

"The purpose of this Thesis is to try to show the effect which certain variables, which are always present in practice, have upon the condensation of Zinc Vapors to Metallic Zinc. That these variables can and do play an important part in the Zinc Smelting Industry can be shown from the fact that all of the zinc obtained at the present time is won from ores by reducing the oxide of zinc to metallic zinc by means of carbon. This operation necessarily takes place at a temperature above the boiling point of zinc. This means that the zinc immediately on …

Flotation Applied To Joplin Sludge, Thaddeus C. Wilson, Gustaf Axel Hellstrand Jan 1913

Flotation Applied To Joplin Sludge, Thaddeus C. Wilson, Gustaf Axel Hellstrand

Bachelors Theses

"The sludge (fine material) which daily is being sent to the tailing dump by the Joplin mills contains values in lead and zinc often in excess, as to percentage, of that of the crude ore. At present no attempt is being made to treat this It is at this point that it is proposed to introduce some flotation process to supplement the ordinary scheme of wet concentration. With this end in view we have conducted a series of experiments in the flotation of a Joplin sludge"--page 2-3.

The Effect Of The Presence Of Certain Base Metals On The Ability Of Amalgams To Catch Gold And Silver, Ray Gould Knickerbocker Jan 1913

The Effect Of The Presence Of Certain Base Metals On The Ability Of Amalgams To Catch Gold And Silver, Ray Gould Knickerbocker

Bachelors Theses

"As a general proposition, the conditions that favor successful amalgamation, and the factors that work against the success of the operation are reasonably well known. We know that if mercury contains certain impurities it will not pick up gold and silver efficiently. We know that if the gold and silver are not in proper condition the mercury will not work as it should. We also know what some of these impurities are, and have some idea as to what condition the gold and silver should be in, but the exact data on these conditions and their effects are lacking. The …

The Nature Of The Reactions Occurring In The Distillation Of Zinc From Its Ores And The Effect On The Speed Of These Reactions Due To Certain Variables, Robert Glenn Sickly, Charles Yancey Clayton Jan 1913

The Nature Of The Reactions Occurring In The Distillation Of Zinc From Its Ores And The Effect On The Speed Of These Reactions Due To Certain Variables, Robert Glenn Sickly, Charles Yancey Clayton

Bachelors Theses

"The reactions that occur in the metallurgy of zinc are in general well known as to the end results obtained. The zinc smelter desires a maximum recovery in a minimum time. There are certain factors that govern the fulfillment of this desire. The most important of these are TEMPERATURE, TIME, KIND OF REDUCTION MATERIAL, and THE NATURE OF THE ORE. There is much data available as to the temperatures at which these reactions go on and also there is obtainable some information as to the speed with which these reactions progress, particularly as to the length of time required for …

The Potato, I. S. Oakland Jan 1913

The Potato, I. S. Oakland

Electronic Theses and Dissertations

I respectfully submit this investigation and thesis to the committee of Master of Science, realizing that a long time is needed for proving any scientific principle no matter how large or small that truth may be. I have labored patiently for the last two years trying to find what part inheritance takes in lowering the yield of tubers in this state. I found that inheritance plays an important part in lowering the yield. I also found that there was a direct relationship of size of seed piece to yield, and that possibly the low yield of today is due to …

The Child's Bible, Leonidas Latimer Loofbourow Jan 1913

The Child's Bible, Leonidas Latimer Loofbourow

University of the Pacific Theses and Dissertations

Every lover of scripture takes a Bible for himself within our larger one. He may read the 60 books from a sense of duty or profit, but there are portions that he loves, which he reads time and again. Those are the Bible within the Bible that he has made for himself. Any Bible used long and effectively by one person has this story to tell. Torn edges, pencillngs, thumbmarks plentiful here, and large sections of clean pages there show what the owner may never have dreamed, that he has his personal edition of our common Bible. This is inevitable. …

The Psychology Of Senescence: An Introductory Study, Charles W. St. John Jun 1912

The Psychology Of Senescence: An Introductory Study, Charles W. St. John

Historical Dissertations & Theses

The following biographical studies have been made with the purpose of showing through concrete cases some aspects of mental decline in senescence. To the objection that each of these cases follows a course in a degree divergent from that of normal mental decline, the reply is that a study of these striking instanced, we believe, afford a more ready insight into the underlying phenomena than would a similar one which deals with average or typical cases. The significance of exceptional cases should not be underestimated. Certain peculiar conditions have been present which have modified the typical phenomena, but after due …

Housing Conditions In Worcester, Harry L. Jackson Jun 1912

Housing Conditions In Worcester, Harry L. Jackson

Historical Dissertations & Theses

The physical basis of the home, the dwelling-place of the family, is inseparably bound up with and affects to a marked degree the standard of the home. If we are at all interested in the present and future welfare of our city it is highly essential that we know what the housing conditions in Worcester are in view of the close relation between home and community.

We must admit that the citizens here as a whole have given the all-important subject of housing very little attention. One must not therefore infer that we have no housing problem. Every American city …

Atmospheric Nitrous And Nitric Acids And Their Absorption By Rain And Surface Water., Alexander Y. Lee May 1912

Atmospheric Nitrous And Nitric Acids And Their Absorption By Rain And Surface Water., Alexander Y. Lee

Electronic Theses and Dissertations

Having been born and brought up in China, an empire, where the people are utterly ignorant of the vital importance of a good system of public water supply, and having decided to take chemistry as my profession, I feel intensely interested in the examination of water for the purpose of convincing our people in the far east to pay proper attention to sanitation on a chemical basis. The average life period there has been roughly estimated to be thirty years, and we have now in the Middle Kingdom a population of 450,000,000. It means in each century we have approximately …

Analysis Of Water-Insoluble Proteins Of Flesh : An Application Of Van Slyke's Method Of Analysis Of Pure Proteins., H. H. Mcgregor May 1912

Analysis Of Water-Insoluble Proteins Of Flesh : An Application Of Van Slyke's Method Of Analysis Of Pure Proteins., H. H. Mcgregor

Electronic Theses and Dissertations

The fundamental importance of a definite knowledge of the quantity of each amino acid yielded by the several food proteins justifies the expenditure of much effort in studying the analytical methods in order that these may be improved or their limitations definitely ascertained." "From the standpoint of physiological chemistry it is highly desirable that the present very limited knowledge of the protein substances of flesh be increased." The desirability of a knowledge of the amino acid content of food proteins has led to much experimentation looking towards a method that will yield quantitative results without involving excessive time or manipulation …

An Abbreviated Scheme For The Detection Of Acid Radicals., Mary Pressley Smith May 1912

An Abbreviated Scheme For The Detection Of Acid Radicals., Mary Pressley Smith

Electronic Theses and Dissertations

In studying qualitative chemistry, two things impress you. The one being, the systematic, inclusive and generally accepted tables for the detection and identification of the several metals; the other, the lack of any agreement as to the method of the identification of acid radicals. The metal analysis tables are so well arranged and so true that even the inexperienced person finds little or no difficulty in working with them. But with the acid radicals, it is an entirely different proposition. There is no generally accepted grouping of the radicals into divisions, some text books giving as many as seven divisions …

Le Misanthrope., Henry William Lenz May 1912

Le Misanthrope., Henry William Lenz

Electronic Theses and Dissertations

The aim of this thesis is to show that there is found in this "noblest of comic masterpieces" an absorbing study of mankind and a profound knowledge of the human heart. It is In his work that man gives himself to the world; in his literary efforts he gives a vivid portrayal of himself, his real and inner self is splendidly revealed, though the merely material man is kept in the background. Bearing this in mind the writer has endeavored not so much to depict the character of Moliere, but, rather by an analytical process, to designate the elements which …
