Melting Point Studies Of Binary Mixtures Of Barbowax 4000 And 1500 And Various Waxes In An Air Chamber, Arnold P. Feider

Bachelors’ Theses

While selecting the subject of research for this thesis the author had the opportunity to consult several thesis conducted at Marquette University on the melting points of waxes.

The Corrosive Effect Of Sodium Acid Sulfite Solution Upon Stainless Steel As Compared With Carbon Steel And Cast Iron, Arthur John Haug

Bachelors’ Theses

Tilghman, in 1866, discovered the fundamental principle of the sulfite process - the treatment of wood with a solution of sulfur dioxide gas in water, with the addition of an alkaline bisulfite. However, he was un­able to pursue this discovery because of the difficulty of obtaining acid resisting materials.

A Generating Voltmeter Of Wide Sensitivity Range For Measuring Atmospheric Potential Gradients, Herschel Roy Snodgrass

Physics & Astronomy ETDs

The specific need for the present instrument arose out of a consideration of the significant results that might be obtained through a coordination of reliable data on potential gradients under various cloud formations with the accompanying fast motion cloud photographs. The characteristics most desired were: (1) the continuous measurement of both the magnitude and polarity of the surface potential gradients over a wide range of values, from normal fair weather gradients of 0 to +300 volts per meter to thunderstorm gradients, possibly as high as 200,000 volts per meter; (2) easy portability; (3) resistance to harmful effects from rain, dust, …

Cambrian Stratigraphy In The Northern Wasatch Region, George Burke Maxey

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An exhaustive field study of the Cambrian stratigraphy of the northern Wasatch region indicates that in addition to the Blacksmith Fork section there are two complete and better exposed middle and upper sections. Several other good exposures of the lower Middle Cambrian section have been studied in detail. The Spence shale is found to be a member low in the Langston, not the basal member of the Ute. Relative ages of the Spence shale and Ptarmigania faunas have been determined. Other Cambrian faunal zones have been discovered and are discussed. Paleontologic evidence suggests that the Nounan formation is of Upper …

Zinc Relationships Of Some Utah Soils, Wilford Derby Laws Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Recent reports from many parts of the United States indicate that the so-called zinc-deficiency disease is wide spread. It affects some varieties of trees in some areas and all varieties in other areas, and occurs from Florida westward to the Pacific coast and northward to the Canadian line. Although the disease is more prevalent in trees, it is also known to affect annual plants.

A recent survey of Utah orchards shows a wide-spread occurrence of little-leaf, a zinc deficiency disease, in fruit trees. The disease was found to be common on the upper sandy soils between Ogden and Salt Lake …

Test 369: Mccormick-Deering Model W-9 (Gasoline), 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 …

An Analysis Of Fishing In The Tva Impoundments During 1939, R. William Eschmeyer, Clarence M. Tarzwell

United States Environmental Protection Agency: Publications

An inventory of fishing on Norris, a storage reservoir, was begun in 1938. The following year it was extended to Wheeler, a run-of-the-river reservoir, and to the tailwater area below Wilson Dam. This inventory, therefore, covered each of the three general types of fish habitats created by the TVA dams. This discussion is a summary of the 1939 fishing data, together with recommendations for fish management based on the creel census information. The data collected totaled 34,270 usable fishing records, representing a catch of 98,495 fishes.

A Study Of A Carbonaceous Gold Ore, James S. Huckaba

Bachelors Theses and Reports, 1928 - 1970

The presence of graphite in the ore of the Missouri-McKee Mine has made its treatment by the methods now used quite unsatisfactory. The study was undertaken to de­velop a new flow sheet which would give a high recovery and yet be economical enough to handle low grade material.

A New Fossil Bovid From Nebraska With Notice Of A New Bison Quarry In Texas, C. Bertrand Schultz

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

An interesting and unique bovid skull was reported to the staff of the University of Nebraska State Museum in 1938 by Mr. Alvin McReynolds of Nehawka, Nebraska. The specimen was found in 1933 in a ravine north of Nehawka by Messrs. Merritt and Harold Dodson, brothers. Although the skull was not in place, it appears to have been washed out of a nearby Pleistocene clay deposit by floodwaters. The specimen is well preserved and is of a dark brown, almost black color. In 1938 it was loaned to the Museum for study and photographing but was not obtained as a …

The Ancestral Ursid, Hemicyon, In Nebraska, Edwin H. Colbert

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

During the summer of 1928, a University of Nebraska State Museum field party, composed of Dr. A. L. Lugn and the writer, made a collection of upper Miocene and lower Pliocene mammals in Brown and Cherry counties, Nebraska. This collection was sponsored and made possible by the generosity of the late Hon. Charles H. Morrill.

A Shovel-Tusked Mastodon, Arnebelodon Fricki, From Kansas, Erwin Hinckley Barbour, Claude W. Hibbard

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

Since the Amebelodontinae were first announced (Barbour 1927), a number of examples of the genus Amebelodon have presented themselves in various parts of Nebraska, Colorado, and in several places in Kansas. Thus its range has already been materially extended, many skeletal parts added, and the hope kindled that knowledge of this remarkable group of proboscideans is destined to be greatly enriched within the next few years. As may be seen in the accompanying lists of the known parts of Amebelodon preserved in various museums, there are already at hand the bones necessary for the assemblage of a nearly complete composite …

A New Species Of Sphenophalos From The Upper Ogallala Of Nebraska, Erwin Hinckley Barbour, C. Bertrand Schultz

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

The genus Sphenophalos was described by John C. Merriam (1909, p. 319-30), who based his description on a fragmentary horn-core (Uni. of Calif. No. 11887) from the late Tertiary deposits near Thousand Creek in northern Humbolt county, Nevada. Knowledge of Sphenophalos, however, is still confined to this single, fragmented type horn-core (Frick 1937, p. 472) and other fragmental specimens (Furlong 1932, p. 27-36).

The Pipy Concretions Of The Arikaree, C. Bertrand Schultz

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

The pipy concretions of the Arikaree (lower Miocene) of Nebraska and adjacent states were first described by Nelson Horatio Darton (1899, p. 743) as "characteristic layers of hard, fine-grained, dark-gray concretions, often consisting of aggregations of long, irregular, cylindrical masses" (see Figures 30, 32, 34, and 35). The individual pipes vary in diameter from a few inches to several feet, and in length from a few inches to a hundred yards or more. Tests demonstrate that pipy concretions are composed of sand cemented by calcium carbonate. When dipped in acid the cement is dissolved and the concretion is reduced to …
