Test 455: Massey-Harris Model 55, 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 …

Oxidation Of Silver As A Method Of Measuring Ozone Concentration, Lorne Maxwell Chanin

Physics & Astronomy ETDs

It has been found that, under certain conditions, a chemical reaction occurs between silver and ozone. The products of this reaction are silver oxides and oxygen. When heated to a certain temperature, the silver oxides are decomposed into silver and oxygen. If this reaction were produced, then the amount of oxygen resulting from the decomposition would be a measure of the amount of ozone originally present.

The Intensity Of Zodiacal Light, Allan F. Beck

Physics & Astronomy ETDs

The study of the intensities measured in the region of the zodiacal light, the second most important contributor to this light of the night sky after starlight has been subtracted, is the purpose of this paper.

Internal Pressure And Related Physical Properties, Eugene Ceperley

Bachelors’ Theses

What is internal pressure? That question has never been answered in a satisfactory manner. Probably the best answer is the simple statement that it is a measure of the attraction between molecules. While this is true it gives no indication of what causes the attractive force or of the effects which this attraction has on a substance.

In this thesis an attempt will be made to use this vague definition of internal pressure to find a method of calculating internal pressure using data for various physical properties. The liquid state of various substances will be considered. A relationship which holds …

Proper Mixtures Of Ellis County Soils For Adobe Construction, And Their Physical Properties Part Ii, Buster Wayne Read, W. G. Read, H. A. Zinszer

Fort Hays Studies Series

Houses made of soil have been built for centuries, but until recently the trend had been away from soil to some other building material. Now, however, adobe is again beginning to be recognized as a satisfactory, reliable building material for our time.

Studies Of Antimony Occurrence With Special Relation To Its Effective Extraction, San Jose Antimony Mines, Wadley, San Luis Potosi, Mexico, J. C. Archibald Jr.

Bachelors Theses and Reports, 1928 - 1970

The mines at San Jose which are within the Wadley unit are the largest antimony mines in Mexico. These mines produce more than half of the antimony produced by the company from its mining operations. Since the time of the author's connection with the company, a number of changes have been made in planning of development work, handling of labor, methods of mine development, cost improvement, and other problems inherent in the successful guidance of an operation.
