The Cost Of Producing Electricity At The Hamilton, Missouri Light And Power Company, Bernerd William Adams
The Cost Of Producing Electricity At The Hamilton, Missouri Light And Power Company, Bernerd William Adams
Bachelors Theses
"For those seeking information on the cost of producing electricity in steam plants, an unlimited amount of data may be found in the technical journals and text books. This information, however, is obtained from a careful analysis of the daily and hourly records kept by the largest central stations, hence, production costs are available only where the yearly out-put is several million kilowatt-hours. the small isolated stations of from one hundred to two hundred kilowatt capacity have not as a rule, become progressive enough to keep a complete record of operating costs...The test hereinafter reported was conducted from August 3rd. …
Leaching Flue Dust, Edwin Alexander Kayser
Leaching Flue Dust, Edwin Alexander Kayser
Bachelors Theses
"The usual method of treatment has been to charge the "flue dust" into reverberatories and smelt it with the regular charge of calcined ore. There was a consequent cost of handling and a serious loss thru furnace draft and boiling, due to the fine state of division of the material and the presence of sulphates, acid, and moisture.
The object of the paper is to treat this material by some leaching process, which will eliminate the above enumerated losses, and at the same time present the finished product at a lower cost, and with a higher extraction per ton, than …

A Study Of A Certain Filled-Sink Ore Deposit, Azmon Thurman Dunham
Bachelors Theses
"This mine, which is located about 3-1/2 miles southeast of Sullivan in the extreme northeast corner of Crawford County, Mo., was first known as the Sullivan and Bridoll Mine of the old Hamilton Iron Company. It has been operated discontinuously since about 1870. Until 1904 it was worked solely as an iron mine, but at that time development work for copper was started, and from 1905 to 1909 to mine treated only this metal. It is not known how many pounds of copper the mine has produced, but during one 20 day run in 1904 of which there is record, …

Flotation Applied To Silicate Sludge, Yaro Klepel, Greene Erskine
Flotation Applied To Silicate Sludge, Yaro Klepel, Greene Erskine
Bachelors Theses
"Within the past few years great success has been made of the flotation of sulfids, and to a certain extent of carbonates.
Since sulfids are easily recovered by flotation it seems practicable that silicates could be made to float by first sulfidizing them, and then subjecting them to ordinary flotation treatment.
This problem involves the treatment of a silicate sludge obtained from the Joplin district, the sludge will easily pass through a 250 mesh screen. At the present time this sludge is being sent to the tailings pond.
The experimental work of this thesis was done along the line of …

Some Chemical Problems In Geology, Reginald Scott Dean
Masters Theses
"This thesis is in the main a compilation of the views held at this institution in regard to the problems discussed as interpreted by the author. No claims for originality are made except in the manner of presentation as the material used has been obtained by conference and class room work with Professor V. H. Gottschalk and Professor G. H. Cox and also to some extent with H. A. Buehler, State Geologist. On the other hand the material is an expression of these ideas as assimilated by the author and hence may in certain cases differ radically from the views …

Bulletin No. 139 - The Movement Of Soluble Salts With The Soil Moisture, F. S. Harris
Bulletin No. 139 - The Movement Of Soluble Salts With The Soil Moisture, F. S. Harris
UAES Bulletins
In irrigated districts, where excessive quantities of water are used, there is usually an accumulation of alkali salts in the soils of the lower lands. These salts are probably dissolved from the soils through which the percolating waters pass and are carried along until the water comes to the surface and is evaporated, when the salts are deposited as a crust at the surface. Many of the most fertile soils of the arid regions have been ruined by the bringing to the surface of soluble salts in such large quantities that the growth of crops is prohibited. The rapidity with …
The Electro Deposition Of Lead In Sugar And Acetate Solutions, Abe Lew Kaplan
The Electro Deposition Of Lead In Sugar And Acetate Solutions, Abe Lew Kaplan
Bachelors Theses

The Electrolysis Of Potassium Lead Tartrate Solutions, Reginald Scott Dean
The Electrolysis Of Potassium Lead Tartrate Solutions, Reginald Scott Dean
Bachelors Theses
"Kahlenberg and Hillyer have shown that lead oxide (PbO) dissolves in neutral potassium tartrate to form a strongly alkaline solution in which the ratio of potassium to lead is 1:1. Since this solution shows a very low concentration of lead ion it might be expected to give a smooth and adherent cathode deposit. The purpose of this thesis is to determine its possible applicability as a refining electrolyte"--page 1.
The Round Ligament Of Nebraska Proboscideans, Erwin H. Barbour
The Round Ligament Of Nebraska Proboscideans, Erwin H. Barbour
Conservation and Survey Division
Comparisons of the acetabula of various mastodons and mammoths common to Nebraska show conclusively that absence of the round ligament is not a characteristic of the proboscidea, as generally accepted. From the specimens in our collections, there is evidence that the ligament was not on! y present, but was uncommonly large and well developed in the earlier Nebraska proboscideans. Examination of material collected since 1891, and preserved in the cabinets of the Nebraska State Museum. and the Morrill Geological Collections, makes it apparent that all Nebraska proboscideans had round ligaments, though perhaps the latest survivors did not.

Nebraska Fossils Which Excite Common Inquiry, Erwin H. Barbour
Nebraska Fossils Which Excite Common Inquiry, Erwin H. Barbour
Conservation and Survey Division
This paper must not be mistaken for a report on the fossils of Nebraska. It is merely a circular letter to correspondents describing and figuring those fossils only which occasion frequent comment. In two recent papers of the Survey consideration was given to the common minerals and rocks of Nebraska, and it seems opportune to briefly discuss our fossils in a like manner. Probably no other State can boast of such a well-preserved and varied fauna.
