The Geology Of The Southern Central Portion Of The Morrison Cave Area., Arthur Talpt Feb 1938

The Geology Of The Southern Central Portion Of The Morrison Cave Area., Arthur Talpt

Bachelors Theses and Reports, 1928 - 1970

Morrison Cave is located about 50 miles southeast of Butte, Montana. It was named after the man who discovered it. Later it was taken over by the State and renamed Morrison Cave State Park. Recently the government with the aid of the Civilian Conservation Corps has built a new road to the cave and has made the interior more accessible. The name of the cave is now Lewis and Clark Cavern National Monument.

Report Of Progress Of The Nebraska State Museum, Erwin H. Barbour Jan 1938

Report Of Progress Of The Nebraska State Museum, Erwin H. Barbour

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

The history and development of the Nebraska State Museum since 1891 have been summarized in a preliminary manner up to 1925 in the first number of Volume I of the Bulletin of the Nebraska State Museum.1 Since 1927, the collections of the Nebraska State Museum, The University of Nebraska, have been housed in a new building, Morrill Hall, on the city campus of The University of Nebraska. It now seems fitting to report upon the exceptional progress of the past few years, and to acknowledge the fine cooperation of those who have helped to make it possible.

Test 303: Allis-Chalmers Model Wc (Distillate), Nebraska Tractor Test Lab Jan 1938

Test 303: Allis-Chalmers Model Wc (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 …


Preparation Of Thianthrene, Eugene Alton Talley Jan 1938

Preparation Of Thianthrene, Eugene Alton Talley

Master's Theses

This work was begun in an attempt to study further the preparation of thianthrene from 2-dichlorobenzene and alkali sulfides. g_-Dichlorobenzene is a liquid by-product in the preparation of its solid isomer, E-dichlorobenzene, which is used extensively for controlling moths and peach tree borers. The study of the preparation of thianthrene from the liquid isomer was undertaken because the preparation might develop into a possible use for the large quantities available.

Thianthrene might be made from 2-dibromo- and 2-diiodo-benzene but these are not as cheap or as easily obtained as the dichloro derivative and were not used in this study various …


Orthogonal Polynomials With Orthogonal Derivatives, M. S. Webster Jan 1938

Orthogonal Polynomials With Orthogonal Derivatives, M. S. Webster

Department of Mathematics: Faculty Publications

We are concerned with the following assertion:
THEOREM. If {φn(x)} and { φn’(x)} are orthogonal systems of polynomials, then {φn(x)} may be reduced to the classical polynomials of Jacobi, Laguerre, or Hermite by means of a linear transformation on x.


The Effects Of Certain Salts Upon The Saccharogenic Activity Of Three Typical Enzymes, George F. Gastler Jan 1938

The Effects Of Certain Salts Upon The Saccharogenic Activity Of Three Typical Enzymes, George F. Gastler

Electronic Theses and Dissertations

In a previous investigation carried out in these laboratories, Moxon and Franks (1), have shown the toxicity of sodium salts of selenium, vanadium, arsenic and tellurium toward the production of carbon dioxide during yeast fermentation of glucose. The toxicity of the salts occurred in the order given. In the same investigation (1), it was shown that sodium sulfide and sodium sulfite exert an accelerating effect.

Petrographic Analyses Of The Chepultepec Sandstones Of The Norris Reservoir Region, Tennessee, Chilton Eaton Prouty Jan 1938

Petrographic Analyses Of The Chepultepec Sandstones Of The Norris Reservoir Region, Tennessee, Chilton Eaton Prouty

Masters Theses

"The Norris Reservoir is located in northeastern Tennessee, in the Appalachian Valley. It includes all or portions of Anderson, Campbell, Claiborne, Granger, Knox, and Union counties. The area is shown by the map of Pate I. It is approximately thirty-five miles long in a northeast-southwest direction and about eighteen to twenty miles wide, in a northwest-southeast direction. The area is bounded on the northwest by the Cumberland escarpment and on the southeast by Clinch Mountain. The other boundaries are arbitrarily drawn near the town of Clinton to the southwest and near Tazewell to the northeast"--Introduction. Location and Nature of the …

The Catalytic Vapor-Phase Hydrolysis Of Benzene And Toluene, Clemens Raebel Maise Jan 1938

The Catalytic Vapor-Phase Hydrolysis Of Benzene And Toluene, Clemens Raebel Maise

Masters Theses

"The vapor-phase synthesis of organic compounds represents a new field of study which has attracted the attention of investigators only within recent years. However, wide interest is apparent in this field and several processes of commercial importance have already been developed. Hydrolysis is perhaps the newest of all the types of vapor-phase synthesis; the literature consists of little more than a few patents...The vapor-phase hydrolysis of benzene and toluene, therefore, presented an interesting possibility. These two hydrocarbons are considered very stable toward water in the liquid-phase. The purpose of this investigation was to determine to what extent their stability toward …
