Rules For Official Tractor Tests, Nebraska Tractor Test Lab, Agicultural Experiment Station
Rules For Official Tractor Tests, Nebraska Tractor Test Lab, Agicultural Experiment Station
Nebraska Tractor Tests
The Nebraska Tractor Law known as House Roll 85, 37th session, which became effective July 15, 1919, was enacted to encourage the manufacture and sale of imporved types of tractors and to contribute to a more successful use of the tractor for farming.
It was thought that the best method of accomplishing these objects would be to require a tractor of each model sold in the State to be tested at the State University and to have the results of these tests made public. These tests will give reliable information on the power capacity and fuel consumtion of each tractor …
Classification Of Springs, Kirk Bryan
Classification Of Springs, Kirk Bryan
United States Geological Survey: Staff Publications
Among the common phenomena of nature, springs are notable because of their high usefulness. Since the earliest times the homes of men have clustered around them. In arid regions their number and size may limit the population. In many humid regions springs are so numerous and similar that distinctions between them are not recognized, yet they may be caused by so many principal and minor factors or by so many combinations of these factors as to make the origin of any one spring exceedingly complex or obscure. An interesting account of the many erroneous notions held by the ancients regarding …

Rules For Tractor Demonstrations, Nebraska Tractor Test Lab
Nebraska Tractor Tests
The object of these rules, instructions and data is to make all tractor demonstrations of this kind comparable and of the greatest educational value. Anyone who has conducted tractor demonstrations in the past has realized the necessity of some standard rules to follow and those who afterwards have referred to the results, deplore the lack of uniformity in the demonstrations and the data. For those who have not had this experience will find that it is a great help to have satisfactory rules to follow.
The value of these demonstrations depends largely upon the accuracy of the data reported on …

Studies Concerning The Elimination Of Experimental Error In Comparative Crop Tests, T. A. Kiesselbach
Studies Concerning The Elimination Of Experimental Error In Comparative Crop Tests, T. A. Kiesselbach
Nebraska Agricultural Experiment Station: Historical Research Bulletins
It is apparent that many sources of error have unconsciously entered into comparative crop yield tests. The very important matter of overcoming variation in soil conditions as a source of experimental error has been quite extensively studied and reported by various investigators during the past decade. The means suggested for reducing such error have been (1) repetition of plats and (2) correction of yields according to check plats planted to a uniform variety or treatment at stated intervals. Both methods have proved of value and a combination of both may often be used advantageously. Some danger always exists of error …
A Theorem On Semi-Continuous Functions, Henry Blumberg
A Theorem On Semi-Continuous Functions, Henry Blumberg
Department of Mathematics: Faculty Publications
Recently G. C. Young and A. Denjoy have communicated theorems—those in Denjoy's memoir are of an especially comprehensive character—dealing, in particular, with point sets where the four derivatives of a given continuous function are identical. It is the purpose of this note to treat an analogous problem that arises when "derivative" is replaced by "saltus." However, instead of confining ourselves to "saltus," we prove a more general theorem that applies essentially to all semi-continuous functions. We preface the proof of this theorem with the following
