Test 347: International Tractractor Model T-6 (Wide Tread) (Distillate), Nebraska Tractor Test Lab Jan 1940

Test 347: International Tractractor Model T-6 (Wide Tread) (Distillate), 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 …

Nebraska In Relation To The Problems Of Pleistocene Stratigraphy, Alvin Leonard Lugn Dec 1939

Nebraska In Relation To The Problems Of Pleistocene Stratigraphy, Alvin Leonard Lugn

Department of Earth and Atmospheric Sciences: Faculty Publications

Nebraska is so peculiarly situated with respect to Pleistocene deposits of glacial, fluviatile, and eolian origin that it holds the key to the solution of many important problems of the stratigraphy of that period. A brief outline of the Pleistocene geology of Nebraska with several illustrations is followed by a statement of and brief discussion of several of these problems. The main problems touched upon are: age of the Loveland loess, Pleistocene classification, correlation with Europe, the need for a better understanding of what is meant by "glacial" and "interglacial," the problem of glacial and interglacial loess, the duration of …


Fermentation Of Sugar Acids By Bacteria, Gordon B. Robbins, Keith H. Lewis Aug 1939

Fermentation Of Sugar Acids By Bacteria, Gordon B. Robbins, Keith H. Lewis

Chemistry Department: Faculty Publications

Bacterial fermentation of the sugar acids has received little attention in comparison with the wide-spread use of the common aldoses and sugar alcohols. These acids, and especially their sodium salts, are well suited to bacteriological techniques because of their solubility and heat stability, yet their usefulness for investigating the relationship of chemical structure to biological utilization has only recently been recognized. Their application to systematic differentiation of bacteria has also been neglected.

Kendall, Bly and Haner (1923) concluded from a study of three monocarboxylic acids and three dicarboxylic acids that these compounds possessed little value for the differentiation of bacterial …


Effect Of Organic Matter Decomposition On The Solubility And Fixation Of Phosphorus In Alkaline Soils, H. F. Rhoades Jun 1939

Effect Of Organic Matter Decomposition On The Solubility And Fixation Of Phosphorus In Alkaline Soils, H. F. Rhoades

Nebraska Agricultural Experiment Station: Historical Research Bulletins

It is the purpose of this bulletin to report a laboratory study on the effects of organic matter decomposition on the solubility and fixation of phosphorus in alkaline soils. The study included the following: (1) a comparison of the effects of a decomposing organic material with those of a physiologically acid nitrogen fertilizer, and (2) a comparison of the effects of different organic materials of varying phosphorus contents.


Effect Of Soil Type, Slope, And Surface Conditions On Intake Of Water, F. L. Duley, L. L. Kelly May 1939

Effect Of Soil Type, Slope, And Surface Conditions On Intake Of Water, F. L. Duley, L. L. Kelly

Nebraska Agricultural Experiment Station: Historical Research Bulletins

In connection with investigations of runoff and erosion in the Great Plains an attempt has been made by means of artificial applications of water to determine certain principles concerning the effect of different soils and soil conditions on runoff and soil erosion. Such information is needed in planning all field operations dealing with soil erosion and moisture control. It is also needed in connection with watershed studies that are being established in the Central Great Plains, dealing with runoff and flood flows from larger areas. The method employed makes it possible to obtain comparable data on a wide range of …


The Comparative Ability Of The Bob-White And The Ring-Necked Pheasant To Withstand Cold And Hunger, Paul L. Errington Mar 1939

The Comparative Ability Of The Bob-White And The Ring-Necked Pheasant To Withstand Cold And Hunger, Paul L. Errington

Other Publications in Wildlife Management

The native Bob-white (Colinus virginianus) and the introduced Ring-necked Pheasant (Phasianus colchicus torquatus) may both, on occasion, suffer severe winter mortality over much of their common range in north-central United States. Their habitats often overlap, although the Pheasant has a greater cruising radius and an ability to live in a more open type of country than the Bob-white. In given localities they also live upon much the same kinds of winter foods.

The scope of this paper is not intended to cover the ecological adjustments of Pheasants or of Bob-whites to their winter environment so much …


A New Giant Camel Gigantocamelus Fricki, Gen. Et Sp. Nov., Erwin Hinckley Barbour, C. Bertrand Schultz Jan 1939

A New Giant Camel Gigantocamelus Fricki, Gen. Et Sp. Nov., Erwin Hinckley Barbour, C. Bertrand Schultz

Bulletin of the University of Nebraska State Museum

A lower Pleistocene deposit containing fossil vertebrates near Broadwater, Morrill county, Nebraska, has been reported upon by the writers, beginning three years ago. Five fossil quarries have been opened since the site was discovered in 1936.


The White River Oligocene Rodent Diplolophus, Erwin Hinckley Barbour, Thompson M. Stout Jan 1939

The White River Oligocene Rodent Diplolophus, Erwin Hinckley Barbour, Thompson M. Stout

Bulletin of the University of Nebraska State Museum

The rich and varied nature of the mammalian faunas of the White River Oligocene has been recognized for many years, but the exact geologic succession is only now becoming known. In these faunal assemblages the rodents and lagomorphs appear to have been important elements, perhaps numerically as abundant in the Oligocene as are these same groups at present.


An Outline Of The Principal Natural Resources Of Nebraska And Their Conservation, George E. Condra Jan 1939

An Outline Of The Principal Natural Resources Of Nebraska And Their Conservation, George E. Condra

George E. Condra Publications

Nebraska is well endowed with important natural resources, such as stone, clay, sand, soil, water, prairie, forests and wildlife. However, soil and water are our basic heritage because they, more than other resources, support native life, agriculture, industry, and social development.


An Outline Of Nebraska's Industries, George E. Condra Jan 1939

An Outline Of Nebraska's Industries, George E. Condra

George E. Condra Publications

The principal industries of Nebraska are summarized into the following groups: mineral, agriculture, manufacturing, transportation and publishing, and trade or mechandizing.

Nebraska Tractor Tests

EXPLANATION OF TEST REPORT: Farmall M Gasoline

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.
