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.

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 …

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

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, …

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 …

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 …

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 …

Supergene Enrichment Of Silver Ores With Special Reference To Those From Neihart, Montana., Thomas Walker Page

Bachelors Theses and Reports, 1928 - 1970

In the development of a technique it was necessary to learn the fundamentals of ore microscopy as applied to the various minerals of silver, which included the use of reflected polarized light, etch reactions, micro­chemical analysis, and sight recognition of mineral. In addition it was necessary to become familiar with the accepted criteria of sequence, replacement, and other textural phenomena.

Geology And Ore Deposits Of The Butte-Highland Gold Mine., Stockton Veazey Jr.

Bachelors Theses and Reports, 1928 - 1970

The Butte-Highland mine is situated at the head of Basin Creek, in the Highland mining district, Silver Bow County, about 14 miles south of Butte. The tunnel portal and present surface plant are at an elevation of about 7350 feet above sea level, facing westward across the head of Basin Creek valley. The "ghost" mining town of Highland lies a mile to the east, near the forks of Fish Creek. Access to the mine is obtained at present from Beaudine's siding, 12 miles west. The property may also be reached, with difficulty, over poor roads from Limekiln hill, or from …

Preliminary Floatation Tests On The Beneficiation Of A Low-Grade Montana Bituminous Coal., William Packwood Given

Bachelors Theses and Reports, 1928 - 1970

Coal is an aggregation of vegetal matter with varying small amounts of mineral and animal matter which have been so changed by the processes of sedimentation, decay and metamorphism that it has become a dense, dark, combustible substance. It occurs in beds varying in thickness from one foot or less to over 300 feet. The horizontal extent of a bed is sometimes continuous over an area as large as the State of Montana.

Auriferous Tertiary Gravels Near Rocker, In Silver Bow County, Montana, William C. Mclaughlin

Bachelors Theses and Reports, 1928 - 1970

Between the villages of Rocker and Silver Bow, in south­western Montana, are found an interesting group of placers. Gold occurs in Tertiary gravel beds that are interstratified with beds of rhyolitic volcanic ash. With the aid of a plane table and open-sight alidade, a small portion of the lake-bed area near Rocker was mapped; all distances were paced, but numerous checks assure a fairly accurate map.

The Age-Hardening Of Duralumin, Allison Richard Dyer

Bachelors Theses and Reports, 1928 - 1970

The development of wrought alloys of aluminum to which high strength and ductility can be imparted by heat treatment began with the work of Wilm and Claesser in Germany, 1905­-1911. During this time an alloy was developed which was later commercially produced in that country under the tradename of duralumin. The need for strong, light alloys for aircraft during the World War greatly hastened the development of duralumin.

Ammoniacal Sulphate Leach Of Ananconda Zinc Calcine Recovery Of The Zinc By Electrolysis., Authur Jewett Bovee Jr.

Bachelors Theses and Reports, 1928 - 1970

Zinc is produced from ores by two general methods, distillation and electrolysis.

The general principles involved in the electrolytic zinc process of today were known as far back as 1880. Difficulties encountered in purifying the solution for electrolysis and lack of suitable mechanical apparatus were the main reasons that such a long time elapsed before the process was used to produce zinc in commercial quantities.

Precipitation Of Gold, Silver, And Copper From Cyanide Solutions On Activated Charcoal., Rayworth Francis Howe

Bachelors Theses and Reports, 1928 - 1970

Charcoal has been known for a considerable length of time to have the property of recovering gold, silver, and copper from cyanide solutions of these metals. Quantita­tive data that may shed light on the mechanism of the re­moval of these metals is very limited except that char­coal in a form known as activated has the power to abstract gold and silver in considerable quantities from the above solutions.

The Effect Of Impurities On The Electrodeposition Of Zinc From Zinc Sulfate Solution Containing Antimony., Emmitt L. Klebba

Bachelors Theses and Reports, 1928 - 1970

It has been proven by research and years of experience, that before electrolytic zinc is possible, the electrolyte, as zinc sulfate solution must be prepared as pure as is economical. In other words, the ideal electrolyte must only be a solution of one metal - zinc. Every other metal and carbon must be excluded if good recovery and a firm deposit is to be obtained.

Alloys Of Lead And Tellurium, Ettore A. Peretti

Bachelors Theses and Reports, 1928 - 1970

Prior to the last few years little practical use was made of the element tellurium, which is obtained from gold and silver tellurides and from the slimes of electro­lytic copper refineries. Lately, however, more study has been made of its properties when alloyed with other metals. It was the purpose of this thesis to study the effects of the addition of tellurium to lead, particularly in small amounts.

Conodonts From The Quadrant Shales Of Montana, Don R. Cubbage

Bachelors Theses and Reports, 1928 - 1970

Conodonts have not been known to exist in Montana prior to the discovery of the specimens discussed and described in this paper. With this fact in mind, the author has endeavored to correlate the species of seven genera found in the Quadrant formation of Montana with similar micro-organisms from other North American areas.

A New Giant Camel, Titanotylopus Nebraskensis, Gen. Et Sp. Nov., Erwin H. Barbour, C. Bertrand Schultz

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

The purpose of this bulletin is to figure and describe a .amel brought to light in the field season of 1933, which seems to be the giant of all camels found in the State. The specimen consists of the right ramus with the symphysial portion. The mandible is 26% inches long, or about the length of one's outstretched arm to the finger tips. This jaw is nine inches longer than that of Camelops kansanus. Such an extraordinary jaw indicates a camel nearly twice as large as Alticamelus altus. In reference to its unusual size we are proposing for it the …

A New Rhinoceros Mount, Trigonias Osborni, Erwin H. Barbour

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

On February 9, 1934, a pair of rhinoceroses, Trigonias osborni, was installed in the Founder's Room in Morrill Hall, the Nebraska State Museum. They are figured and accorded brief consideration here in order to maintain the printed records of such acquisitions in the Nebraska State Museum. The two skeletons, carefully posed, were put in the south wall case to be associated with a pair of Diceratherium from Morrill County. and the mounted skeletons of two Brown County Te leo ceras. In this gallery two long built-in wall cases insure ample facilities for the proper installation of six rhinoceroses, for each …

The Sine-Function, Audrey Siehr

Bachelors’ Theses

Since the sine function is one of the most important elements of that phase of mathematics known as Trigonometry, it is only proper that we pause a moment for a short explanation of that subject. Trigonometry originated with the Greeks as the name itself implies. It was derived from the two Greek words trlgonon, meaning triangle; and metria, meaning measure. Trigonometry, then, dealt with problems related to measuring triangles.

Groups Of Order Eight, Ludwig Eugene Loos

Bachelors’ Theses

The problem of this thesis is to show that there can be only five groups of order eight. Its basis is Kronecker's Theorem, and it demonstrates that, regardless of the number of generators used in composing the groups, the result will always be limited to four groups of order eight. The fifth and last group is a cyclic group formed on eight letters.

The Effect Of Halowax 1012, 1013 & 1014 On The Melting Points Of Various Waxes, Louis Henry Kroening

Bachelors’ Theses

This thesis is concerned with the melting points of various waxes and the effect of Halowax 1012, 1013 and 1014 upon their physical constants. Interest in this problem was aroused "by the fact that Halowax as shown by Nathan Smith in his thesis, "The Effect of Halowax Upon Lubricating Oils and Greases”, decreases the viscosity of oils. Since lubricating oils contain waxes it is logical to expect that this decrease in viscosity is due to the lowering of the melting point of the waxes present. It was to investigate the truth of this assumption that this work was begun.

A Study Of Melting Points Of Various Ternary Mixtures Of Waxes, Leonard Anthony Veranth

Bachelors’ Theses

The work undertaken in this thesis is a continuation of the work done by George John Hable entitled, "A Study of Melting Points of Various Binary Mixtures of Waxes". In the present work, the melting points of ternary mixtures of waxes is studied. The experimental work is presented in the form of graphs so that the reader is afforded a better representation and clearer conception of the work done and the results obtained.

The Effect Of Ultra-Violet Light On Ethyl Acetate, Homer W. Wiesner

Bachelors’ Theses

The present work, is a study of the effect of ultraviolet light on pure organic compounds. In particular, it is a qualitative and quantitative study of_ the decomposition products of ethyl acetate as effected by ultraviolet radiations, together with the development of experimental apparatus. In as much as the work required special apparatus, much of the time was spent in the development and construction of such apparatus.

A Method Of Determining The Relative Thermal Conductivities Of Liquids, Lohr Arthur Burkardt

Bachelors’ Theses

This thesis concerns the development of apparatus suitable for the practical determination of the thermal conductivity of liquids. The data presented in the literature refers to the deter­mination of absolute conductivity values and-is very unsatisfactory from a practical point of view. The aim here has not been to furnish abso­lute data, but to provide a simple means of determining the relative conductivity of any series of liquids. Knowing such a set of rela­tive conductivities, absolute values can readily be calculated therefrom.

The aim has been to develop an apparatus that is simple enough to be constructed in the ordinary laboratory, …
