Test 379: Bear Cat Model 3000-1, Nebraska Tractor Test Lab

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 …

Physical And Chemical Properties Of Soil Profiles Of The Burchard And Steinauer Series, Henry W. Smith, H. F. Rhoades

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The purpose of this bulletin is to report an investigation of the soils mapped as types of the Burchard and Steinauer series. Burchard soils are described as nearly mature Prairie soils, and Steinauer soils as Lithosols, by the Division of Soil Survey. The C horizons of soils of both series consist of calcareous glacial drift. A part of the conclusions drawn from the investigation of these soils is based upon observations made in the field in southeastern Nebraska, the remainder upon laboratory data for samples taken by horizons from nine profiles.

Corona Discharge From Antenna Wire: A First Partial Report, Robert Katz

Robert Katz Publications

Purpose: 1. To examine the conditions for corona at the surface of a wire. This report is a theoretical discussion. No test procedure was used.

Conclusions:
1. Calculation of the gradient at the surface of the fixed-wire liaison antenna (bare copperweld, .040" diameter) on the B-17 airplane indicates that it is of the order of 200 times the gradient measured at the top generating voltmeter.
2. Further work will be done by the Special Devices Branch in an attempt to determine the conditions under which insulated wire goes into corona.

Censusing Pheasants By Detonations, H. Elliot Mcclure

Nebraska Game and Parks Commission: Staff Research Publications

A study of the ecology and management of the ring-necked pheasant (Phasianus c. torquatus) was begun in Nebraska in the spring of 1941. Prime among the objectives of the survey was to devise some method by which the populations could be estimated or counted. In conjunction with roadside counts as practiced in Minnesota, Iowa, Ohio, Pennsylvania and other states, attempts were made to derive a closer estimate than by that method. Every game technician working with roadside counts of pheasants realizes the difficulties involved. Having had success in estimating the numbers of mourning doves by counting their calls …

On Certain Arithmetical Functions Due To G. Humbert, M. A. Basoco

Department of Mathematics: Faculty Publications

G. Humbert has discussed, in a series of brief notes, a certain class of entire functions with interesting arithmetical properties. These functions are defined, in an essentially unique manner, by certain functional equations. The Fourier series representations of the solutions of these equations are similar in form to those for the elliptic functions snu, cnu, dnu, and so on. They differ from these, however, in that their domain of validity extends throughout the entire complex plane (Z_∞ excluded) and moreover, in that their arithmetized forms involve incomplete numerical functions of the divisors of an integer.

A Theorem On The Unit Groups Of Simple Algebras, Ralph Hull

Department of Mathematics: Faculty Publications

Let k be an algebraic number field of finite degree m and let A be a normal simple algebra of degree n, order n², over k. Our object is to prove the following theorem.
THEOREM. If A is an R-algebra, that is, if n>2 or at least one infinite prime place of k is unramified in A when n=2, then any two distinct maximal orders of A have distinct groups of units.

Nitrate Production As Affected By Grain-Crop Residues On The Surface Of The Soil, T. M. Mccalla, J. C. Russel

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The purpose of this bulletin is to present the data on nitrate contents and nitrate production in tests where straw or stalk residues were left on the surface through subsurface tillage, as compared with check treatments where these residues were plowed under or were absent. Nine of these tests were at Lincoln, Nebraska, and one was at the Hastings, Nebraska, Hydrological Project. Two tests were conducted in 1939, four in 1941, and four in 1942.

X-Ray Inspection Of Castings (Army Air Forces' Requirements), Robert Katz

Robert Katz Publications

The author contributed a brief account of the radiographic practices necessary to comply with government specifications to a round table discussion on inspection methods at the last American Society for Metals Convention, and later was able to release for publication in Metal Progress a full set of the radiographic standards set up about a year ago to govern acceptance of structural castings for airplanes. Representaive negatives are reproduced in this article. Those eliminated are either of similar defects which did not register strong enough to appear on an engraving without retouching, or of defects readily observed by visual inspection without …

Pheasant Weights And Time Of Season In Relation To Meat Production In Nebraska, Levi L. Mohler

Nebraska Game and Parks Commission: Staff Research Publications

During the 1942 pheasant hunting season in Nebraska 479 bagged cock pheasants were weighed in western and southwestern counties. Analysis of the weights revealed that the time of the open season apparently has a material effect upon the tonnage of meat harvested for human consumption.

On The Fourier Developments Of A Certain Class Of Theta Quotients, M. A. Basoco

Department of Mathematics: Faculty Publications

In this paper we shall be concerned with the functions φ^k_a(z) defined by the relation
(1) φ^k_a(z) ≡{d/(dz)logℓ_α (z,q)}^k = {[ℓά(z,q)] ÷ [ℓα(z,q)]^k, α + 0, 1, 2, 3,
where ℓ_α(z, q) is a Jacobi theta function and k is a positive integer. In the first place, we shall derive the Fourier developments which represent these functions in a certain strip of the complex plane; it …

Missourian Triticites Of The Northern Mid-Continent, Benjamin H. Burma

Department of Earth and Atmospheric Sciences: Faculty Publications

The tendency toward fine discrimination in fusulinid species has made necessary standardization in their study. Theories and practices of fusulinid study are herein discussed in some detail. Four new species of Triticites are described from the Missouri series of the Pennsylvanian system; one species from the Virgil series and two froim the Missouri are redescribed, and the characters of the other five known Missourian species from the northern mid-Continent are shown in graphs, thus bringing together the known Missourian species. Finally consideration is given to the ontogeny and phylogeny of the group.

Vegetation Of The Northern Part Of Cherry County, Nebraska, William L. Tolstead

Conservation and Survey Division: Faculty and Staff Publications

Agricultural practices in the Great Plains of North America are now in a period of adjustment from a traditional agriculture initiated by pioneer farmers to a grazing economy based upon potentialities of climate and soil. The attainment of a proper system of land use has been retarded in many localities by the lack of definite information concerning the vegetation and its indicator significance. In this study of the vegetation of Cherry County, Nebraska, the interrelations between the plants and their environments are discussed, the dominant species are described, and changes in grasslands caused by seasons, grazing, and climatic cycles are …

Physical And Chemical Properties Of Soil Profiles Of The Scott, Fillmore, Butler, Crete, And Hastings Series, Henry W. Smith, H. F. Rhoades

Nebraska Agricultural Experiment Station: Historical Research Bulletins

For the studies reported here most of the samples were taken in the spring of 1940 from the walls of deep pits dug in areas previously selected by surveyors and inspectors as type locations for the Butler series. To elucidate certain points, samples were taken from the upper part of several other profiles, also called Butler, the following year. In addition to this work on the characterization of the Butler series, further data have been collected concerning soils of the Scott, Fillmore, Crete, and Hastings series. Profile samples were obtained from type locations of each of these series. The data …

Parabos Dodsoni Barbour And Schultz: A Correction, Erwin Hinckley Barbour, C. Bertrand Schultz

Department of Earth and Atmospheric Sciences: Faculty Publications

A Bos-like animal, Parabos dodsoni, was recently described by Barbour and Schultz (1941, "A New Fossil Bovid from Nebraska", Bull. Univ. Nebr. State Museum, Vol. II, No. 7, pp. 63-66, Figs. 24-27, December) as a new genus and species from the Pleistocene of Nebraska. Attention has been called to the writers by Dr. E. H. Colbert of the American Museum of Natural History that the name Parabos is preoccupied. Parabos was introduced as a generic name by C. Arambourg and J. Piveteau (1929, "Note preliminaire sur un Ruminant du Pliocene inferieur du Roussillon," C. R. Bull. Soc. Geol. de …

A Review Of The Daimonelix Problem, C. Bertrand Schultz

University Studies (University of Nebraska) (1888–1984)

THE first paleontological expedition of the University of Nebraska State Museum was organized in the summer of 1891 and was led by Erwin H. Barbour, now Director Emeritus of the Museum. The most important and interesting discoveries made during the season were some very peculiar spiral fossils called by the field party "Devil's Corkscrews," or Daimonelix,l which were found in the Miocene deposits near Harrison in Sioux County, Nebraska. During the fifty years that have intervened scientists have tried to determine the origin of these strange forms. Several controversies arose, and although various theories have been proposed, none as yet …

The Basic Analogue Of Kummer’S Theorem, J. A. Daum

Department of Mathematics: Faculty Publications

About one hundred years ago, E. E. Kummer proved the formula
(1) ₂F₁ [_{1 + a – b} ^{a, b; -1}] = [Γ(1 + a - b)Γ(1 + a/2) ÷ Γ(1+a)Γ(1+a/2 - b)
which has since been known as Kummer's theorem. This appears to be the simplest relation involving a hypergeometric function with argument ( - 1).
All the relations in the theory of hypergeometric series _rF₈ which have analogues in the theory of basic serie3 are those in which the argument is ( + 1 ) …
