Operational Characteristics Of A Small Sewage Oxidation Lagoon, Karlheinz C. Muhlbauer

Masters Theses

"With the rapidly increasing population in the United States the adequate disposal of sewage has become one of the major technical problems which the sanitary engineer has to solve. In most areas it is no longer acceptable practice to discharge domestic sewage or industrial waste products directly into streams or lakes because of the resulting pollution of the water, which may later be used for drinking or recreational purposes. Many larger cities have, therefore, adopted some method of sewage treatment which renders such wastes safe and unobjectionable before they are discharged into a lake or stream. Most of these methods …

Surface Temperature Measurement Of Metal Undergoing Induction Heating, Ding-Yee Nee

Masters Theses

"It is the object of this thesis to investigate the possibility of using thermoelectric pyrometry for surface temperature measurement of metal undergoing induction heating. The temperature range under investigation, as stated before, is 400 °F to 1250 °F. This research may actually be treated by two sections.

The first section concerns the methods of using thermocouples for ordinary surface temperature measurements. The second section concerns the effect, if any, on thermocouple e.m.f. readings while it is measuring the surface temperature of a metal undergoing induction heating. The first section of the investigation has been well covered by literature and will …

Methods To Improve The Metallurgy Of Bolivian Tin Ores, Oscar Davila-Michel

Masters Theses

"Tin is a rare element; among the base metals it is one of the rarest. Although it was one of the first metals used by man and has been used since prehistoric time, the ore-dressing and metallurgical methods of tin are inefficient and very wasteful.

The only tin deposits of importance in the Americas are located in Bolivia, South America, and it is in Bolivia that the problems of tin metallurgy are greatest. More than 50% of the tin that is mined in Bolivia is lost in the tailing dumps of the beneficiation plants. In a country where the export …

Performance Parameters Of Low-Density Ammonium Nitrate Base Explosives; Experimental Results And J. Taylor's Method, Mohammad Azhari Warga-Dalem

Masters Theses

"Ammonium nitrate has been known to the explosive industry for a long time. Compelled by the ever increasing mining costs, in 1954 "Akremite" was introduced to the market. It is a simple carbonaceous ammonium nitrate mixture and is the cheapest explosive available to the open-pit operators.

During the following years considerable amount of research was done, resulting among others with the introduction of ammonium nitrate-hydrocarbon mixtures as an explosive. During the Second World War research was done toward the refinement of the hydrodynamic theory. Several methods of calculating the detonation velocities of the explosives were introduced: Brown (1942), Kistiakowski and …

Design Of Distillation Solvent Recovery System, Donald Empson Puyear

Masters Theses

"With the advent or the atomic bomb during the summer of 1945 the opportunity for engineering colleges to provide an integrated course of study in the field of nuclear engineering was presented. This opportunity has been greatly enhanced by a policy of the Atomic Energy commission, granting funds to selected institutions for equipment necessary for successful instruction in this field. The Missouri School of Mines and Metallurgy, realizing the opportunity presented, has established a course of study in nuclear engineering in which the departments of Ceramic, Chemical, Mechanical and Metallurgical Engineering and Physics are taking an active part.

That portion …

A Statistical Approach To The Zonation Of A Petroleum Reservoir, Leroy Allan Beghtol

Masters Theses

"The problem of dividing a reservoir into distinct permeability zones, in order to predict fluid flow and thereby the production history of the field, has long troubled the petroleum engineer. As a solution to this problem a new statistical method for zoning a reservoir was developed, using a modification of the analysis of variance technique. The application of the statistical zonation procedure to permeability data obtained from eight closely spaced wells substantiated the validity and effectiveness of the new method in determining distinct permeability zones"--Abstract, page iii.

Test 639: Ford Model 841l (Lpg), Nebraska Tractor Test Lab

Nebraska Tractor Tests

This report and any related files are made available to the online through the Lester F. Larsen Tractor Test and Power Museum as resources allow. Established in 1998, this museum is located on the University of Nebraska-Lincoln East Campus. It is and appropriately housed within the walls of the historic 1920 Nebraska Tractor Test Laboratory, where the first tractor test was started on March 31st, 1920. Because the pioneer tests became worldwide standards, this location was designated as a Historic Landmark of Agricultural Engineering by the American Society of Agricultural Engineers in 1980, shortly after testing was moved to a …

A Learning Index For The Midget Wiggly Block Test For Mechanical Ability, James Franklin Winegarden

Dissertations and Theses @ UNI

The writer became interested in testing mechanical ability while taking a course in the 1957 summer session at the Iowa State Teachers College dealing with the problem of teaching industrial arts. The teacher of this course was Dr. Howard O. Reed who had devised the Midget Wiggly Block Test for Mechanical Ability, which will be referred to hereafter in this report as the Midget Wiggly Block Test. During a class presentation, Reed state that there may be a learning process involved in the repeated assembling of the Midget Wiggly Block Test and presented a single formula for computing a score …
