Test 273: Caterpiller Model Rd-4 (Diesel), Nebraska Tractor Test Lab Jan 1936

Test 273: Caterpiller Model Rd-4 (Diesel), 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 …

Note On The Greatest Integer Function, M. A. Basoco Jan 1936

Note On The Greatest Integer Function, M. A. Basoco

Department of Mathematics: Faculty Publications

In this note we wish to record certain finite sums involving the greatest integer function E(x), which seem to be of some interest. Hermite* has shown that the generating function for E(x) has the simple form, (1) xb ÷(1 -x)(1 -xa) = Σ(n)E[(n + a - b) ÷ a]xn, where a, b are positive integers. To him is due, likewise, the development (2) ) xb ÷(1 -x)(1 + xa) =Σ(n)E1[( …


The Sorption Of Fluoride Ion With Special Reference To Fluoride Removal From Potable Waters, Phillip W. West Jan 1936

The Sorption Of Fluoride Ion With Special Reference To Fluoride Removal From Potable Waters, Phillip W. West

Theses and Dissertations

The recent discovery that even very small concentrations of fluorides in drinking waters are sufficient to cause the serious dental dystrophy commonly known as mottled enamel, has around widespread interest and concern. Federal and State surveys have been conducted to determine the geographical distribution of the malady, and the fluoride contents of water supplies.

County dental surveys, conducted by the United States Public Health Department with the cooperation of local dentists, have located the regions throughout the country where mottled enamel is endemic and among these localities is an area in southeastern North Dakota and adjacent territory in South Dakota …


A Preliminary Study Of The Characteristic Physical Properties Of Chlorinated Asphalt, Ernest Clifford Spafford Jan 1936

A Preliminary Study Of The Characteristic Physical Properties Of Chlorinated Asphalt, Ernest Clifford Spafford

University of the Pacific Theses and Dissertations

The introduction of chlorine into hydrocarbon compounds produces a product with properties markedly different from those of the original hydrocarbon. Methane, a gas at ordinary conditions, becomes methyl chloride, still a gas but having a higher condensation point than methane, upon the substitution of one chlorine atom in place of a hydrogen atom per molecule of methane. Upon the introduction of three atoms of chlorine per molecule of methane, chloroform, a very volatile liquid, is formed, and upon the introduction of four atoms of chlorine carbon tetrachloride, a less volatile liquid is produced.

Chlorination takes place in a “saturated” hydrocarbon …

Microscopic Study Of Montana Silver Ores., Edwin Johnson May 1935

Microscopic Study Of Montana Silver Ores., Edwin Johnson

Bachelors Theses and Reports, 1928 - 1970

A microscopic investigation of the Montana silver minerals was conducted. This study consisted mainly of identifying the silver and silver-bearing minerals and of determining their paragenetic rela­tionships. The increasing amount of research in which the reflecting microscope is employed is evidence of the great value of this method of approach in the solution of problems of paragenesis of the opaque minerals.

A Preliminary Study Of The Ostracoda Of The Big Snowy Group, Mississippian, Of Montana., John C. Rabbitt

Bachelors Theses and Reports, 1928 - 1970

In the field, samples were taken vertically and horizon­tally along the various outcrops in different sections of central and south-central Montana. At important localities the samples were taken about every half-foot verti­cally; in other sections they were taken every few feet.

The Preparation Of Calcium And Barium Gluconate, Ronald Anthony Plzak May 1935

The Preparation Of Calcium And Barium Gluconate, Ronald Anthony Plzak

Bachelors’ Theses

The privilege of working on this subject is one which the author has sincerely appreciated, as it has given him the opportunity of incorporating many of the more recent contributions along the line of oxidizing aldose sugars. In reviewing these contributions, he has abstained from conveying an impression of finality and has attempted to show the many possibilities which the free sugar acids offer for the future. The experience of the last few years has proved that even long-cherished conceptions and apparently well-established facts may at any time undergo drastic revision. For this reason, the author has referred directly to …


The Extraction Of Tantalum And Columbium From Tantalite, Stanley P. Wisniewski May 1935

The Extraction Of Tantalum And Columbium From Tantalite, Stanley P. Wisniewski

Bachelors’ Theses

In the summer of 1932, the Milwaukee Public Museum, sent an expedition to the Bad Lands and Black Hills of South Dakota, under the direction of Dr. Ira Edwards, Curator of Geology in that institution. It was at this time that the author, a member of this group, while studying the pegmatites of the Black Hills, became interested in the tantalum-columbium bearing minerals of that region, namely tantalite and columbite. At that time the writer made a detailed mineralogical study of these two minerals, as well as a thorough investigation of their occurrence in that region. In the fall of …


Sensitivity Of Curcumin As An Organic Reagent In Testing For Beryllium, James W. Bookhamer May 1935

Sensitivity Of Curcumin As An Organic Reagent In Testing For Beryllium, James W. Bookhamer

Bachelors’ Theses

For many years the analytical chemist avoided by design or more probably by accident the general use of organic chemicals in his work. Some few of them he accepted as a matter of course, and perhaps without much thought of their organic nature. In qualitative analysis he used chloroform as a solvent in testing for bromine and iodine. A few indicators were in common use, but organic chemicals were used but little in analytical work. It was not until the twentieth century that their use in analytical procedures received any worthwhile attention. Since then they have rapidly come to the …
