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 …
On A Theorem Of Hölder, Donald W. Miller
On A Theorem Of Hölder, Donald W. Miller
Department of Mathematics: Faculty Publications
A well-known result, due to Hölder [1], is the following: The symmetric group Sn, has outer automorphisms if and only if n = 6. The classical proof of the existence of a class of outer automorphisms of S6, as formulated by Burnside [2], rests in part on the theory of primitive groups and entails extensive computation. In this note we offer a direct method for constructing such automorphisms. The author is grateful to Professor R. H. Bruck for raising this problem and for subsequent helpful remarks.

Field Techniques For Sexing And Aging Game Animals, Donald R. Thompson
Field Techniques For Sexing And Aging Game Animals, Donald R. Thompson
Nebraska Game and Parks Commission: Publications
The purpose of this booklet is to provide a ready field reference for identification, sexing and aging of common game species. It has purposely been kept in simplified form, presenting only those techniques which can commonly be applied in the field and avoiding those which would require special equipment and skills. Untrained personnel should be given demonstrations of the techniques, and thereafter this reference should serve as a reminder. It is not expected that the reference could successfully be used without such demonstration. Certain of the techniques such as cloaca! examination of waterfowl may require considerable practice by the individual. …

Other Publications in Wildlife Management
Surprisingly few Americans have any definitive or comprehensive knowledge of the history of their country, although many are under the delusion that their school book history taught them all they needed to know.
They were indoctrinated with a smattering of dates which included the voyage of Columbus and the landing of the pilgrims at Plymouth. They learned what Priscilla said to John Alden, gloated over the Boston Tea Party and memorized part of Patrick Henry's speech; they were briefed on Bunker Hill, Washington crossing the Delaware and the Surrender of Cornwallis. And that just about completed that era.

ABOUT THE TEST REPORT AND USE OF THE DATA The test data contained in this report are a tabulation of the results of a series of tests. Due to the restricted format of these pages, only a limited amount of data and not all of the tractor specifications are included. The full OECD report contains usually about 30 pages of data and specifications. The test data were obtained for each tractor under similar conditions and therefore, provide a means of comparison of performance based on a limited set of reported data. EXPLANATION OF THE TEST PROCEDURES Purpose The purpose of …

Physics, Chapter 7: Work And Energy, Henry Semat, Robert Katz
Physics, Chapter 7: Work And Energy, Henry Semat, Robert Katz
Robert Katz Publications
An extremely important concept that has been developed in physics is that of the work done on a body by the action of some external agent which exerts a force on this body and produces motion. For example, whenever someone lifts a body, he does work by exerting a force upward on it and moving it upward. Whenever a steam locomotive pulls a train, a series of processes takes place in the steam engine of the locomotive which enables it to exert a force on the train and move it in the direction of the force. The term work, as …

Physics, Chapter 30: Magnetic Fields Of Currents, Henry Semat, Robert Katz
Robert Katz Publications
The first evidence for the existence of a magnetic field around an electric current was observed in 1820 by Hans Christian Oersted (1777-1851). He found that a wire carrying current caused a freely pivoted compass needle in its vicinity to be deflected. If the current in a long straight wire is directed from C to D, as shown in Figure 30-1, a compass needle below it, whose initial orientation is shown in dotted lines, will have its north pole deflected to the left and its south pole deflected to the right. If the current in the wire is reversed and …

Physics, Chapter 13: Properties Of Matter, Henry Semat, Robert Katz
Robert Katz Publications
When a system is subjected to external forces, it generally undergoes a change in size or shape or both. We have thus far touched very lightly on such changes; for example, we have considered the change in length of an elastic spring and the change in volume of a gas when such systems were subjected to varying pressures. The changes produced in a system by the action of external forces depend upon the physical properties of the material of which the system is composed. A study of the properties of matter leads to information which is of practical value to …

Physics, Chapter 1: Fundamental Quantities, Henry Semat, Robert Katz
Robert Katz Publications
Physics is a fundamental science dealing with matter and energy. By convention, the subject matter of physics has been divided into such topics as mechanics, heat, sound, light, and electricity. In addition to these general classifications, present-day physics includes atomic physics, nuclear physics, solid-state physics, chemical physics, biophysics, and many other subdivisions. It is impossible to include all aspects of physics in a single definition or paragraph, and to distinguish physics clearly from its nearest neighbors, the other physical sciences-astronomy., chemistry, and geology.

Physics, Chapter 14: Temperature, Henry Semat, Robert Katz
Robert Katz Publications
Temperature is one of the fundamental concepts of physics. We are all able to recognize that some bodies are hotter than others, but our temperature sense is qualitative rather than quantitative and is capable of only a limited range. The sense of touch can frequently be used to distinguish between hotter and colder objects, provided that these lie in a temperature range consistent with the stability of human tissue. Even within this range the sense of touch is often unreliable as a measure of temperature.
The metal bracket holding a wooden rail may feel much colder to the touch than …
Physics, Chapter 5: Force And Motion, Henry Semat, Robert Katz
Physics, Chapter 5: Force And Motion, Henry Semat, Robert Katz
Robert Katz Publications
All of us have many times had the experience of setting a body in motion. If we analyze any of these experiences, we readily recall that in each case some force was required to start the object moving. In throwing a ball, moving a piece of furniture, or pulling a sled, the force needed to start the object moving is supplied by one's muscular effort as a push or a pull. In more complex cases, such as setting a car or an airplane in motion, the analysis, although more complicated, will also show that a force is required to start …

Physics, Preface, Henry Semat, Robert Katz
Robert Katz Publications
This book is intended for students of science and engineering; it aims to develop both an understanding of the important concepts of physics and some analytical skill in the solutions of problems. The mathematical level of the book is such that it may be used by students who are taking a course in calculus concurrently.
The notations and methods of the calculus are introduced early in the text, beginning with the concept of a derivative in the discussion of motion, and are then extended to more complex problems as the student progresses both in physics and in mathematics. Vector algebra …

Physics, Chapter 8: Hydrostatics (Fluids At Rest), Henry Semat, Robert Katz
Robert Katz Publications
From our everyday experience, we have become familiar with the fact that matter occurs in three different forms-solid, liquid, and gas. Under ordinary conditions stone, iron, copper, and chalk, for example, are solids; water, oil, and mercury are liquids; air, hydrogen, and carbon dioxide are gases. Each one of these forms is called a phase. At times it is difficult to distinguish clearly between the solid and the liquid phases, as in a material such as tar which flows under the action of a force at ordinary temperatures. Metals at high temperatures flow or "creep" under the action of a …
