Evidence Of Dinosaurs In Nebraska, Erwin Hinckley Barbour

Bulletin of the University of Nebraska State Museum (1924–2023)

Nebraska has long been a collecting ground famous for its fossil mammals, but as yet no dinosaurian bones have been reported, nor have they been expected. The distal end of a finely preserved femur, however, has recently been brought to light, supposedly occurring in position in the Dakota formation of eastern Nebraska. It was discovered, collected, and donated by Mr. J. B. White, (University of Nebraska, Law, class of 1899) on his farm two miles south of Decatur, in northeastern Burt County, near the Missouri River. It was found in undoubted Dakota sand associated with many leaf impressions. This is …

The Giant Beaver, Castoroides, And The Common Beaver, Castor, In Nebraska, Erwin Hinckley Barbour

Bulletin of the University of Nebraska State Museum (1924–2023)

Respecting the giant beaver, Castoroides, in Nebraska, four occurrences can be reported. Of rodents in general the dawn. was in the early Eocene, at which time there were in existence certain squirrel-like members of the order. Rodents are a persistent group, and are among the smallest, most distinctive, most numerous and widely distributed orders of terrestrial mammals. No other order boasts of so many species, the number being between nine hundred and one thousand. In spite of wide divergencies and modifications adapting them to various modes of life, such as climbing, burrowing, swimming, flying, leaping, and running, there is remarkable …

A Morning's Consignment Of Proboscidean Freight, Erwin Hinckley Barbour

Bulletin of the University of Nebraska State Museum (1924–2023)

In the accompanying cut the array of great tusks outlined through their rough crates may lack attractiveness, nevertheless the assemblage is quite out of the ordinary, and seems worth recording in bulletin form. In all museums, and like institutions, freight and express deliveries are matters of daily routine; however, the morning's freight shown in the cut is unique. Herein is represented the more showy portion of the proboscidean freight received at the Nebraska State Museum in a single consignment, in the field season of 1930. The other boxes of mammoth skulls, jaws, and bones, received at the same time, are …

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 …

A Certain Multiple-Parameter Expansion, H. P. Doole

Department of Mathematics: Faculty Publications

C. C. Camp has shown the convergence of the expansion of an arbitrary function in terms of the solutions of the systems of equations
X_1’ (λa₁ - Σ_i=2ⁿμ_i)X₁ = 0,
X_1’ (λa_i + μ_i)X_i = 0, (j = 2, 3, …, n),
where the a_i’s are functions of x, with the boundary conditions
X_i(-π) = X_i(π), (j = 1, 2, …, n).
In this paper it is intended to use a …

Parametric Solutions Of Certain Diophantine Equations, T. A. Pierce

Department of Mathematics: Faculty Publications

In this note parametric solutions of certain diophantine equations are given. The method of obtaining the solutions is derived from an equation involving the determinants of certain matrices. It will be recognized that the method is a generalization of the method of Euler and Lagrange which depends on forms which repeat under multiplication. The matrices used in this paper must be such that their forms are retained under matric multiplication and addition. When integer values are assigned to the parameters of our solutions we obtain integer solutions of the particular equation under consideration; however not all integer solutions are necessarily …

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. …

A New Crinoid Slab, A Bit Of Mississipian Sea Bottom, Erwin Hinckley Barbour

Bulletin of the University of Nebraska State Museum (1924–2023)

Crinoids are popularly known as stone-lilies, featherstars, and sea-lilies. The word lily is a misnomer, and many, misled by the name and by the lily-like form, associate crinoids with the plant kingdom. The name, feather-star, seems explicit for it refers to the feathery arms surrounding the cup or calyx, and expresses relationship to the starfishes and their kind. The cup is attached to a stem, and the stem is anchored to the ocean floor by so-called roots, which are really hold-fasts, or anchors. These features may be seen in the diagram at the end.

The Conservation Of Nebraska's Water Resources, G. E. Condra

George E. Condra Publications

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.

Underground Plant Development In Its Relation To Grazing, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

Grasslands or grazing lands are relatively dry lands. Drought, at least in the surface soil, is always imminent. The necessity for the seedling to make immediate and extensive contact with deeper, moister soil is apparent. The water relation is usually controlling, and the success or failure of the seedling largely depends upon its ability to develop an absorbing system adequate in extent and activity to furnish the necessary supply.
