Nebraska Tractor Tests
All tractors tested at the Nebraska Tractor Test Laboratory were certified by their manufacturers as being stock model machines, conforming to specifications filed with the application for test. No special or high-test fuels were used except as recommended by the manufacturer as necessary.
All results within the official tractor test report were actually attained in tests and are without correction or allowances for friction, temperature, altitude, etc. The results were initially accomplished with the tractor in charge of skilled operators employed by the University.
Unless otherwise noted, each tractor was apparently in good condition at the end of the testing …

EXPLANATION OF TEST REPORT: John Deere GP
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.

On The Trigonometric Expansion Of Elliptic Functions, M. A. Basoco
On The Trigonometric Expansion Of Elliptic Functions, M. A. Basoco
Department of Mathematics: Faculty Publications
The problem of expressing an elliptic function in terms of infinite sums of trigonometric functions has been treated by Hermite, Briot and Bouquet, A. C. Dixon and others. In the present paper we treat the same problem from the point of view of Cauchy's residue theorem in function theory, which is also Briot and Bouquet's starting point, but we differ from these authors in that the integrand we use leads to an expansion for an elliptic function which is valid in an arbitrarily wide, but finite, strip of the complex plane, and which contains certain classical results as special cases. …

Oxygen is the first immediate necessity of life and water is second. Both directly and indirectly and more than soil, water is our most basic resource. It is the universal solvent and without it there would be no life, and, of course, no agriculture and industry.

Amebelodon Sinclairi Sp Nov., Erwin H. Barbour
Bulletin of the University of Nebraska State Museum (1924–2023)
Amebelodonts are so new and so rare that even fragmentary facts relative to the group seem worth publishing. The specimen under consideration is a mandibular tusk found on the farm of Mr. A. S. Keith, Freedom, Frontier County, Nebraska, on the Morrill Geological Expedition of 1928, and is numbered 1-17-7-28, S. and L., the collectors being Bertrand Schultz and John LeMar, both of the class of 1931, the University of Nebraska. The formation was Late Pliocene or Pleistocene.

On Polynomial Solutions Of A Class Of Linear Differential Equations Of The Second Order, W. C. Brenke
Department of Mathematics: Faculty Publications
Certain well known polynomials have a number of common properties. They arise as coefficients of tn in the expansion of a generating function ; they may be obtained by means of orthogonalization of a set of functions xⁿg(x) when the function ρ(x) = g2(x) and the interval are properly chosen ; they may be regarded as polynomials which become orthogonal when multiplied by a proper factor g(x) ; they satisfy a certain type of difference equation ; they satisfy a certain type of differential equation. The results …

Matrices Whose Characteristic Equations Are Cyclic, T. A. Pierce
Department of Mathematics: Faculty Publications
One of Sylvester's theorems f on matrices states that if the characteristic equation
(1) | M - λI| = f(λ) = 0
of a square matrix M has the roots λ1, λ2, … , λn, then the characteristic equation
(2) | φM - ρI| = = g(ρ) = 0
of any integral function of M, namely, φM, has the roots ρi = φ (λi), i = 1, 2, … , n. In this note an isomorphism is shown to exist between …

Nebraska Facts, Walter Kollmorgen
Conservation and Survey Division: Faculty and Staff Publications
Nebraska Facts, compiled by Walter Kollmorgen in the 1930s for the Conservation and Survey Division of the University of Nebraska, presents a concise statistical and descriptive overview of the state of Nebraska during the early twentieth century. The publication synthesizes data on Nebraska’s geography, climate, natural resources, agriculture, industry, transportation infrastructure, public health, and education. Emphasis is placed on the state’s agricultural productivity, manufacturing capacity, and favorable economic indicators, reflecting Nebraska’s role as a leading contributor to national food production and livestock markets during this period. The work also highlights public institutions, including the capitol building and the University …

Seed Potato Treatment Tests For Control Of Scab And Rhizoctonia, R. W. Goss, H. O. Werner
Seed Potato Treatment Tests For Control Of Scab And Rhizoctonia, R. W. Goss, H. O. Werner
Nebraska Agricultural Experiment Station: Historical Research Bulletins
Potato scab annually takes a very large toll from the potato growers of Nebraska. Rhizoctonia causes considerable loss each year, particularly in the early-potato sections, where it decreases stand and yield. These losses are caused by infection from both the soil and the seed. The investigations reported in this paper deal only with the control of the infection arising from the seed. Even though potato seed treatments have been recommended for many years, the diversity of recommendations being made at present by various agencies is very confusing to the grower and research worker alike. Many of the reports from different …
