Some Aldehyde Condensation Derivatives Of Creatinine, Clarence England Denoon Jr.
Some Aldehyde Condensation Derivatives Of Creatinine, Clarence England Denoon Jr.
Master's Theses
When insulin, a substance which is used to reduce sugar in the blood is hydrolysed, products are obtained bearing some similarity to creatinine. Therefore, reasoning conversely, creatinine derivatives might be expected to posses as a hypo- glycemic (sugar reducing) effect.
The Brocard Points Of A Triangle, Mary Geraldine Stamm
The Brocard Points Of A Triangle, Mary Geraldine Stamm
Bachelors’ Theses
The Brocard points, two remarkable points related to a triangle, were first noticed in 1816 by August Leopold Crelle. In a paper published in Berlin, he showed how to determine a point inside a triangle, so that the angles (taken in the same order) formed by the lines joining it to the vertices are equal. Investigations were also made by Karl Friedrich Andreas Jacobi (1795-1855) of Pforta, and by some of his pupils. However, interest in these researches died out, and the matter was soon forgotten.
Exotic Ancient Forests Of Washington, George F. Beck
Exotic Ancient Forests Of Washington, George F. Beck
All Faculty Scholarship for the College of the Sciences
The greatest fossil forest in the world is located within easy driving distance of the University of Washington campus in the State of Washington, near the Columbia River, east of the city of Ellensburg. Mr. George F. Beck, a member of the faculty of the Ellensburg State Normal School, and a former graduate student of the College of Forestry of the University of Washington, discovered this forest, which is now known as the Ginkgo Forest State Park. Aside from its importance from a scientific point of view, this "petrified forest," which contains a greater variety of species than any other …

Department of Earth and Atmospheric Sciences: Faculty Publications
RESIDENTS within an area of 50,000 to 75,000 square miles in Nebraska, Iowa, Missouri and Kansas were awakened by mild but distinct earth tremors at 5:00 and 5:03 A.M. on March 1. No damage of any importance has been reported. Two distinct tremors occurred, each lasting about 10 seconds, about 3 minutes apart.

The Application Of Differential Equations To The Laws Of Physics, Sherman Baker
The Application Of Differential Equations To The Laws Of Physics, Sherman Baker
Bachelors’ Theses
In this treatment of the mathematical expression of physical laws, all proofs and expositions of problems that are taken from particular books are acknowledged in the text. Formulas and proofs that are given in a conventional form by authors generally and are the property of no single man are not acknowledged. Such are the alternating current equations, the Mass Action formulas, parts of the thermionic current discussion, and Fourier's equation for the flow of heat.
Some preparation in the sciences on the part of the reader is taken for granted in the presentation of the matter on this thesis. The …

A Geological Report On Several Localities Of Madison County, Montana, Hans Fritzsche
A Geological Report On Several Localities Of Madison County, Montana, Hans Fritzsche
Bachelors Theses and Reports, 1928 - 1970
The area selected for study comprises four different districts situated in Madison County, each of them showing typical geologic features: the South Boulder District, the "Montana type section of Paleozoic and Mesozoic rocks", the Mayflower District with the famous Mayflower mine, the Renova Hot Springs District as an excellent area for studying structural features, and the Silver Star Mining District with its contact metamorphic ore deposits.
A Preliminary Study Of The Micro-Fauna Of Certain Paleozoic Formations Of Montana, George Powe
A Preliminary Study Of The Micro-Fauna Of Certain Paleozoic Formations Of Montana, George Powe
Bachelors Theses and Reports, 1928 - 1970
The study of the micro-fauna of Montana formations has been almost entirely neglected. Because the petroleum industry of this state has not felt the necessity for using micro-paleontology in its sub-surface correlations, the science has been but little used. The Montana Power Company has had an examination made of some of its well cuttings by a competent micro-paleontologist who found some foraminifera in Mesozoic sediments. However, no investigations have been made to determine the presence and character of the micro-fauna of the Paleozoic formations of Montana.

The Effects Of Zinc Sulphate, Manganese Sulphate, And Iron Sulphate On The Lead Storage Cell., George A. Mccracken
Bachelors Theses and Reports, 1928 - 1970
The lead storage battery as it is used today is made up of the pasted type plates of lead dioxide, the anode, and sponge lead, the cathode, and wooden or hard rubber separators, which serve to insulate these from one another. In manufacturing these, it is desirable to keep them free from impurities.

The result obtained in this paper is as follows:
The series Σni[((p + 1)(p +3)…(p +2n -1)) ÷(2nn!) X((p-1)/2)n (x), where Xn(p-1)/2(x) (hereafter indicated simply by Xn) is a symmetric Jacobi polynomial p >-1, and i a positive integer, is summable (C, k),k>i—1/2, for the range -1 <x<1.

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 (1924–2023)
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 …

A New Miocene Dog, Mesocyon Geringensis, Sp. Nov., Erwin Hinckley Barbour, C. Bertrand Schultz
Bulletin of the University of Nebraska State Museum (1924–2023)
A field party from the Nebraska State Museum consisting of Messrs. E. L. Blue, Frank Crabill, Loren Eiseley, and C. Bertrand Schultz, on August 28, 1931, was fortunate in finding the remains of a new Mesocyon. This specimen, number 4-28-8-31, the Nebraska State Museum, was found in the Gering formation (lower Miocene), fifteen feet above the Brule, 400 feet west of the road in Redington Gap, near the center of the S. 1/2, sec. 14, T. 19 N., R. 52 W., west of Bridgeport, Morrill County, Nebraska.

Gnathabelodon Thorpei, Gen. Et Sp. Nov. A New Mud-Grubbing Mastodon, Erwin Hinckley Barbour, George F. Sternberg
Bulletin of the University of Nebraska State Museum (1924–2023)
In February, 1932, while opening a gravel pit to get material for highway construction, the skull, tusks, and mandible of a new longirostral mastodont were found by Robert Arnold on his ranch, Sec. 24, T. 12 S., R. 22 W., 1 1/2 miles due east of Ogallah, Trego County, western Kansas. This point is located about 20 miles west and three miles north of Hays, the seat of the Fort Hays Kansas State College, in the museum of which the above mentioned specimen is mounted and exhibited. When unexpectedly exposed by Mr. Arnold and his associates, the great skull was …

Selenium In Proteins From Toxic Foodstuffs, Edgar Page Painter
Electronic Theses and Dissertations
The importance of the selenium problem has been established. Knight (1) in an address before The Association of Official Agricultural Chemists summarized the progress made on the problem, conservatively emphasized its importance, and stressed the need for extensive research. It is a paramount problem not only in South Dakota, but in many other states as well.
