A New Fossil Peccary, Prosthennops Niobrarensis, From Brown County, Nebraska, Edwin H. Colbert
A New Fossil Peccary, Prosthennops Niobrarensis, From Brown County, Nebraska, Edwin H. Colbert
Bulletin of the University of Nebraska State Museum
During the summer of 1929, the writer, accompanied by Mr. Paul O. McGrew of the University of Nebraska, discovered during the course of excavations for fossil vertebrates in northern Brown County, Nebraska, a fairly complete peccary skull referable to the genus Prosthennops. This skull, due to its several unusual characters, as well as to its fair degree of completeness, would seem to warrant a special and a rather detailed description. Consequently the specimen has been kindly turned over to me by Dr. E. H. Barbour, Director of the Nebraska State Museum, not only for the purpose of the present …

Some Contributions To Iodometric Technique, Justin Kimber Dyche
University of the Pacific Theses and Dissertations
Analysis is a very important branch of chemistry, for it is such a practical part of the science. Analysis is itself divided into two parts. Qualitative analysis discovers what things are present in the material in question. Quantitative analysis then determines how much of each ingredient is present. This thesis considers a limited section of quantitative analysis.
This thesis deals with the use of iodine in volumetric analysis, which is called either iodimetry or iodometry. In this type of analysis, the iodine is used in solution and reacts with some other material, also in solution, and takes up electrons. That …

Pre-Pennsylvanian Stratigraphy Of Nebraska, Alvin Leonard Lugn
Pre-Pennsylvanian Stratigraphy Of Nebraska, Alvin Leonard Lugn
Department of Earth and Atmospheric Sciences: Faculty Publications
Sioux quartzite, granite, and schistose metamorphic rocks have been recognized in the pre-Cambrian. The present irregularities, the "basins and highs," on the pre- Cambrian surface are the result of erosion and a long structural history. In general succeedingly younger rocks rest unconformably by overlap against the pre-Cambrian "highs." The principal erosional and structural "highs" are: the "Nemaha mountains," the Cambridge anticline, the Chadron dome, and the Sioux Falls area. "Basins," or saddle-like depressions, occur on the pre-Cambrian surface between the "highs." The largest of these trends from southeast to northwest across the central part of Nebraska. The history of each …
Arrowhead Making In The Ginkgo Petrified Forest, George F. Beck
Arrowhead Making In The Ginkgo Petrified Forest, George F. Beck
All Faculty Scholarship for the College of the Sciences
In a sense we must give the Indians credit for being the original discoverers of these fossil forests of Central Washington. Not that I have been able to run down any legends or traditions regarding fossil logs or any certainty that the Indians recognized them as trees in stone. My opinion is that they could not have failed to recognize them as trees. Be that as it may, they long ago took recognition of the fact that certain logs were to be prized as the source of flint for their arrow-heads.
The Relation Of Drouth To Water-Use In Nebraska, G. E. Condra
The Relation Of Drouth To Water-Use In Nebraska, G. E. Condra
George E. Condra Publications
Three severe drouths have occurred in Nebraska and adjacent states within the past eighty years, and less severe ones have come at moderately regular intervals. Their influence on the agricultural development of the state is well known, but their relation to water supply in general is not so well understood. This paper is a brief review of the relation of drouth to soil moisture, surace water, and groundwater supplies.

Hampton Tusk Of Mastodon, Emmett J. Cable
Hampton Tusk Of Mastodon, Emmett J. Cable
Mastodon Tusk Background Material
On September 23, last, there was unearthed a large tusk in a gravel pit on the farm of W. S. Heuermann, section 21, Reeve township, Franklin County, about four miles south of the town of Hampton, Iowa. While loading gravel, one of the workmen noticed something sticking out of the gravels that resembled a horn. Upon closer examination it was found to be a giant tusk, the largest of its kind, according to the best information available, ever found. The tusk was complete before it was broken by the workmen. The length was 11 feet, 7½ inches, while the circumference, …
Effect Of Varying Supports On Nickel As A Catalyst In The Hydrogenation Of Unrefined And Refined Soy Bean Oil, Nate W. Fredman
Effect Of Varying Supports On Nickel As A Catalyst In The Hydrogenation Of Unrefined And Refined Soy Bean Oil, Nate W. Fredman
Bachelors’ Theses
Hydrogenation is a subject that has grown in importance only within the last thirty years. Before 1900, little was known about the process of adding hydrogen to a liquid oil to form a solid fat, the latter of which has a great deal more uses than the former. Much trouble was experienced, since conditions controlling the process must be very definite in order to obtain good results.
Chemists have found that the main requisite in the above process is the catalyst. It must be very carefully prepared and controlled. But instead of using only the catalyst, many modern research workers …
The Important Lines In A Triangle, Jane Bogiel
The Important Lines In A Triangle, Jane Bogiel
Bachelors’ Theses
Geometry, as one of the fields of Mathematics, has been the object of extensive studies in ancient, Greek times, as well as in modern times, times of revival of scientific interests and researches. Analytical, descriptive, and projective geometry has been introduced as means of symplifying the study of the relations of different geometrical elements. Consequently, pure geometrical methods have been almost altogether abandonned, and, it is only in introducing basic geometrical concepts that they are now used. --This, however, seems to be the only reasonable course as long as the new methods do not change the basic structure of the …
Identification Of Carboxylic Acids As The Salts Of Benzylamine, Cora Louise Carson
Identification Of Carboxylic Acids As The Salts Of Benzylamine, Cora Louise Carson
Masters Theses
Molecular compounds have become of increasing interest in organic chemistry since they furnish a valuable group of derivatives for the identification of certain classes of organic compounds, notably, the aromatic hydrocarbons, the amines, and the phenols. In the identification of such compounds it should be pointed out, as Kamm has stated, that the reactions used in the identification of inorganic compounds, namely, color tests, precipitation of an insoluble compound, and decomposition with certain reagents, can be used merely as indications, not as final tests of identification. In identifying any single chemical individual Wise pointed out that it often becomes necessary …

Change Of Conductivity Of Silicic Acid Gels Upon Setting, Robert W. Gurry
Change Of Conductivity Of Silicic Acid Gels Upon Setting, Robert W. Gurry
Honors Theses
The problem of how electrical conductivity of colloidal sols changes during setting has been a source of much speculation for a long time. Work has been done upon a variety of sols and gels with various and oftentimes conflicting results. The purpose of this investigation was to find out whether the conductivity of a silicic acid sol changes during setting or not; and, if so, how it varies. It was also hoped that the results might lead definitely to some theory of gelation and gel structure.
Effect Of Silicic Acid Gel On The Determination Of Ph, Robert L. Griffeth
Effect Of Silicic Acid Gel On The Determination Of Ph, Robert L. Griffeth
Honors Theses
The general purpose of this investigation, as well as many other investigations made on silicic acid gels at Union College, has been to obtain data which may help to formulate an idea of the gel structure and the process of setting of silicic acid gels. The specific object of the research was to determine whether or not the quinhydrone electrometric set-up for measuring the pH of a solution gives the correct pH of a solution in which there is silicic acid gel present. Since a large amount of data has been taken in connection with silicic acid gels in the …

The Effect Of Various Indicators On The Time Of Set And Ph Of The Silicic Acid Gels, Antonia L. Digesero
The Effect Of Various Indicators On The Time Of Set And Ph Of The Silicic Acid Gels, Antonia L. Digesero
Honors Theses
This work is a continuation of the work started by M. J. Suter. The first part of the work consisted in repeating with extreme accuracy the work already done. Next, the work was continued under the careful guidance of Professor Hurd. The method of determining the PH values of setting gels by indicators has long been in use. It is very useful, but not as accurate as the electrometric method, as the measurements can be made in a short time. The purpose of the research was to find out whether the gels affect the various indicators. This was done by …

Investigations Concerning Bentonite Deposits Near Ramsay, Montana, Anton A. Anjel, John F. Sullivan
Bachelors Theses and Reports, 1928 - 1970
The purpose of Part I of this report is to determine the origin of the bentonite deposits, also to locate them with reference to section corners in the vicinity and to determine their extent.
The field work for this report was done in the fall of 1933 and during the spring of 1934. The roads, geologic contacts, and culture in general were mapped with the use of an open sight alidade and plane table. Distances were determined on the roads by the speedometer on the automobile; the detailed survey in the immediate vicinity of the deposits was done with use …
