Test 173: Fordson Model F (Kerosene), 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 …


On Polynomial Solutions Of A Class Of Linear Differential Equations Of The Second Order, W. C. Brenke Jan 1930

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 Jan 1930

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 …

Alfalfa Production In A Grassland Climate, J. E. Weaver Jan 1930

Alfalfa Production In A Grassland Climate, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

The importance of root extent and activities in relation to the supply of subsoil moisture has again been clearly demonstrated. In fact, it has been shown to be the chief problem in the continued production of alfalfa in a grassland climate.

Studies extending over a period of 15 years have shown that the native species of the tall-grass prairie never exhaust the water supply below that available for plant growth, except rarely in the shallower soil. The subsoil is always moist, and plants root deeply. Of 43 species typically representative of the flora, only 14 per cent absorb almost entirely …


Relation Of Increased Water Content And Decreased Aeration To Root Development In Hydrophytes, J. E. Weaver, W. J. Himmel Jan 1930

Relation Of Increased Water Content And Decreased Aeration To Root Development In Hydrophytes, J. E. Weaver, W. J. Himmel

Department of Agronomy and Horticulture: Faculty Publications

The dependence of root development of most plants upon aeration is clearly shown by water-logging the soil. In a few days, the usual cultivated plants turn yellow, show wilting, and may ultimately die. If the water is kept well aerated, plants may survive though submerged for weeks. Exclusion of oxygen from the roots of most plants interferes with the respiration of the protoplasm of their cells. This results in the death of the cells and consequently the roots fail to function as absorbers for the plant (22).


Hydracarina From Glacier National Park, Ruth Marshall Jan 1930

Hydracarina From Glacier National Park, Ruth Marshall

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Material for this study consisted of collections of water mites made by Dr. R. M. Muttkowski in Lake McDonald, Glacier National Park, Montana, during the months of July and August, 1925. The author wishes here to express her thanks to Dr. Muttkowski for the opportunity to examine this material and thus to add a little to our scanty knowledge of the Hydracarina of the Rocky Mountain region.

Nearly five hundred individuals were secured; these represented seven genera and ten species, one of which is new and one undetermined. About three fourths of the number were Pionas and Limnesias, each genus …


Homes For Birds, E. R. Kalmbach, W. L. Mcatee Jan 1930

Homes For Birds, E. R. Kalmbach, W. L. Mcatee

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Birds appeal strongly to the interest and affection of mankind. Not only do they charm by their graceful forms, harmonious colors, sprightly actions, and usually pleasing notes, but they have an even more important claim upon our esteem because of their great economic value.

Birds feed upon practically all insect pests. They are voracious, able to move freely from place to place, and exert a steady influence in keeping down the swelling tide of insect life.

For economic as well as for esthetic reasons, therefore, an effort should be made to attract and protect birds and to increase their numbers. …


Seed Potato Treatment Tests For Control Of Scab And Rhizoctonia, R. W. Goss, H. O. Werner Dec 1929

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 …


Effect Of Cultural Methods And Maturity Upon The Seed Value Of Eastern Nebraska Potatoes, H. O. Werner Dec 1929

Effect Of Cultural Methods And Maturity Upon The Seed Value Of Eastern Nebraska Potatoes, H. O. Werner

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Seed potatoes as good as northern stocks have been produced under a straw mulch in eastern Nebraska by experimenters and growers. Occasionally reports are heard that a lot of seed potatoes has been grown in eastern Nebraska by ordinary cultural methods for many years, apparently without loss of vigor or yielding capacity. In view of this situation it seemed advisable to investigate this problem to determine whether, and to what extent, environment and maturity as such influence the productivity of seed potatoes and also whether it is feasible to produce satisfactory seed potatoes in the southern and eastern portions of …


The Mandible Of Amebelodon Fricki, Erwin H. Barbour Dec 1929

The Mandible Of Amebelodon Fricki, Erwin H. Barbour

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

The type specimen of the genus Amebelodon is installed in the Nebraska State Museum, the University of Nebraska, Lincoln. It consists of a mandible with tusks and teeth, all of which are dense and perfect, barring minor cracks and breaks. One toe bone and part of a rib found associated with this mandible may belong to this animal. It was discovered by Mr. A. S. Keith on his farm near Freedom, Frontier County, Nebraska; was secured for the palaeontological collections of Hon. Charles H. Morrill by Mr. Phillip Orr, April 4, 1927; was briefly described and figured in a Museum …

The Abortion Problem In Farm Live Stock, L. Van Es Oct 1929

The Abortion Problem In Farm Live Stock, L. Van Es

Nebraska Agricultural Experiment Station: Historical Circulars

Successful animal husbandry is fundamentally dependent on the efficient reproduction and preservation of young stock. Not only are losses among the latter a prolific source of direct economic damage, but they also tend to create an equally serious disadvantage of a more indirect nature. Losses of young animals, unless a reduction of our live stock population can be tolerated, necessitate the setting aside of a larger number of females for purely reproductive purposes than would be required if such losses were not a factor.

Relation Between The Development Of Root System And Shoot Under Long- And Short-Day Illumination, J. E. Weaver, W. J. Himmel Oct 1929

Relation Between The Development Of Root System And Shoot Under Long- And Short-Day Illumination, J. E. Weaver, W. J. Himmel

Department of Agronomy and Horticulture: Faculty Publications

Relatively few investigations have been made to determine the factors which affect the relation of the growth of roots to tops. A more exact knowledge of the relations between aerial and subterranean plant parts and the degree to which these may be modified through cultural practices is of great scientific and practical importance. Extensive investigations have shown that plants exhibit marked specific and varietal differences with respect to relative development of roots when grown under the same environmental conditions. Intensive studies on the growth of wheat by Weaver, Kramer, and Reed (20) and of certain other plants by Crist and …


On The Nature And Cause Of "The Walking Disease" Of Northwestern Nebraska (Necrobiosis Et Cirrhosis Hepatis Enzootica), L. Van Es, L. R. Cantwell, H. M. Martin, J. Kramer Jul 1929

On The Nature And Cause Of "The Walking Disease" Of Northwestern Nebraska (Necrobiosis Et Cirrhosis Hepatis Enzootica), L. Van Es, L. R. Cantwell, H. M. Martin, J. Kramer

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The "walking disease" of Northwestern Nebraska is essentially an enzootic necrobiosis and cirrhosis of the liver due to a toxic agent and does not materially differ from similar disorders occurring in other regions or countries. The disease affects horses and cattle but it is most commonly encountered in the former. The disease in all its clinical and pathological manifestations may be reproduced with the utmost fidelity by the feeding with plants of Senecio riddellii.


A Recent Theory Of Ballad-Making, Louise Pound Jun 1929

A Recent Theory Of Ballad-Making, Louise Pound

Department of English: Faculty Publications

Professor Gordon Hall Gerould's article entitled "The Making of Ballads"' is an attractive essay, written in the fluent and polished manner that we are accustomed to expect from this scholar. It has charm of style, and its positions, taken as a whole, may be termed accepted positions. Because of its literary quality, because it brings together in one paper what has hithert been stressed in scattered places, and because of its appreciation of the poetical quality of those English and Scottish ballads sough out by the notable collectors of the earlier nineteenth century and made available in the volumes of …


A Study Of The Oxidation Of D-Glucose With Air In A Saturated Solution Of Barium Hydroxide, Clyde Wilson Eddy May 1929

A Study Of The Oxidation Of D-Glucose With Air In A Saturated Solution Of Barium Hydroxide, Clyde Wilson Eddy

Open Access Master's Theses (through 2010)

The conversion of one aldose into another aldose and several ketoses slowly by weak alkalis at ordinary temperatures and quickly with much decomposition at elevated temperatures, was first observed by Lobry de Bruyn and later investigated by Nef and his students in an elaborate study on the action of strong alkalis alone and with oxidizing agents extending over a period of ten years. The results of these studies on oxidation were interpreted as depending on the presence of several intermediate enediols. The oxidation of sugars in approximately six normal alkali medium with air or oxidizing agents all give about the …
