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

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

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

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

Bachelors Theses

"The experiments, while hardly sufficiently numerous, seemed to indicate that sugars do not have a good effect on cathodic lead deposits"--Conclusion, page 14.

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.

Contribution To The Chemistry Of Oils And Fats With Particular Reference To Butter Fat, Edward Bertram Holland

Doctoral Dissertations 1896 - February 2014

Experiments in animal nutrition have constituted a prominent line of investigation at the Massachusetts Experiment Station ever since its organisation, but not until 1890 was any attempt made by this station to ascertain the effect of feed on the composition of butter fat.

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.

Nebraska Rocks Which Excite Common Inquiry, Erwin H. Barbour

Conservation and Survey Division

This leaflet it intended to serve as an answer to correspondents who make inquiry about the rocks of Nebraska¹. Unfortunately for those interested in such matters, the rocks of the State are few in number, and are deeply buried from view by sand and soil, so there are thousands of square miles in which even a pebble is a rarity. That our rocks are level and undisturbed is practically true. Still there are some surprisingly interesting folds and faults.

Nebraska Minerals Which Excite Common Inquiry, Erwin H. Barbour

Conservation and Survey Division

The Minerals, Rocks, and Fossils of Nebraska, which Excite Common Inquiry, are treated brefly in leaflets numbered 37, 37a, 37b, respectively. These are intended to serve as circular letters to correspondents. Possibly they may prove to be acceptable and helpful in a measure to teachers and others who conduct parties of school children on field excursions.
