An Experimental And Theoretical Investigation Of The Preferred Orientation In Deformed And Recrystallized Hafnium, David S. Gould

Doctoral Dissertations

"The research problem, as presented, therefore became two-fold; first to investigate and determine the feasibility of fabrication of hafnium and secondly to study the deformation characteristics of the material in light of the overall study of hexagonal metals aimed at the development of an overall general theory of plastic deformation. This appeared to envolve a study of the operating deformation systems in hafnium and the theoretical and experimental study of the textures resulting from plastic deformation. These were to be analyzed in comparison with the other hexagonal metals.

It became evident immediately that the research techniques which must be evolved …

A Study Of The Variation Of The Fluoride Content Of Certain Waters In The Vicinity Of Albuquerque, E. Metz Beahm

Chemical and Biological Engineering ETDs

In the first part of 1935, the City of Albuquerque was investigating the possibility of obtaining an additional water supply from the Jemez Mountains, which are about fifty miles to the north of the City. Black and Veatch, consulting engineers for the City, were asked to make a complete study of the problem. The question of fluorides in the water came up because it was known that the fluorides would cause mottled enamel in human teeth when the water was used during childhood, if the content was above 0.9 parts per million by accepted fluorine analysis methods. The question arose …

Evaluation Of Commercial Titanium Alloys, Robert Loucks

Bachelors Theses and Reports, 1928 - 1970

Uses of titanium and its alloys range from aircraft structures to corrosion-resistance applications. The properties of the metal, including physical metallurgy, naturally dictate the folds of application. The interstitial elements, plus aluminum and tin, preferentially stabilize the alpha phase of titanium.

Test 606: John Deere 720/730 All-Fuel, Nebraska Tractor Test Lab

Nebraska Tractor Tests

EXPLANATION OF TEST REPORT: John Deere 720/730 All-Fuel TEST A: The manufacturer's representative operates the tractor for a minimum of 12 hours using light to heavy drawbar loads in each gear. This serves as a period for limber up, general observation and adjustments. Adjustments that are permissible include valve tappet clearance, breaker ,point gap, spark plug gaps, clutch and others of a similar nature. No new parts or accessories can be installed without having mention made of it in the report. No data' are recorded during this preliminary run except the time that the engine is operated.

Transistors Applied To An Fm-Fm Airborne Radio Telemetery System, R. H. Gablehouse

Electrical and Computer Engineering ETDs

The two semiconductor elements commonly used in transistor production, silicon and germanium, were discovered by two European chemists. A Swedish chemist, Jons Jakob Berzelius, separated and identified silicon in 1823. Germanium was discovered and named by a German chemist, Clemens Alexander Winkler in 1886.

Hydraulic Model Studies Of Culvert Operation, Eugene M. West

Kentucky Transportation Center Research Report

Since 1951 the Division of Research has been engaged in a comprehensive study of highway drainage problems. This study has included special investigations of rainfall and runoff, drainage structures in use and the practices used in their design, culvert hydraulics, and other relevant investigations. To date, reports have been published concerning runoff and rainfall variables (1 and 2)* and the effects of barrel roughness upon culvert operation (3), together with the preparation of a drainage manual for the use of Highway Department engineers and consultants.

The most recent special project, part of the over-all study, has dealt with the effects …

A Field And Laboratory Examination Of Weathering Effects On Petroleum And Blended Petroleum-Natural Asphalts In Paving Mixtures, Ellis G. Williams

Kentucky Transportation Center Research Report

The relative merits of various asphalts and asphaltic materials have been the subject of considerable controversy almost from the beginning of flexible pavement construction in this country. In this early period petroleum asphalt had not yet entered the picture and controversy centered about naturally occurring products such as Trinidad natural asphalt and impregnated stones. In 1876 Congress directed that comparative service tests be made on a rock asphalt* and a sheet asphalt containing Trinidad natural asphalt. The sheet asphalt was considered the more successful of these and thus Trinidad natural asphalt became firmly established as a paving material in this …

Analysis Of Pavement Riding Quality: A Triaxial Evaluation Of Pavement Roughness, William S. Foy

Kentucky Transportation Center Research Report

For the last twenty-five years considerable research has been directed toward developing reliable equipment for evaluating pavement roughness. Since roughness inhibits passenger riding comfort and safety, as well as inducing vehicle deterioration, the determination of the features that cause roughness would indicate possible improvements in pavement design, materials, construction practices and equipment. For example, certain types of base design might be found to produce smoother surfaces than others; and a construction practice such as a blade-spread leveling course might result in more uniform pavements. Then too, evaluation of pavement roughness would permit relative comparison of pavements as one of several …

Test 602: Massey-Harris 444 Lp, 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 …
