Skeletal Parts Of The Columbian Mammoth Elephas Maibeni, Sp. Nov., Erwin Hinckley Barbour

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

The skeletal parts of Elephas columbi are said to be unknown, although teeth, jaws, and skulls are common enough. Columbi is a mammoth of southern adaptation, hence its parts are found from Nebraska southward. Elephas columbi occurs abundantly throughout the State and many examples are preserved in the Nebraska State Museum, as will be seen in an accompanying list.

Tetrabelodon Abell, Sp. Nov., Erwin Hinckley Barbour

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

Brown County, Nebraska, which has been so prolific of long-jawed mastodons, has yielded another form which seems to be new and which may throw light on certain small tusks that occur where Tetrabelodon bones abound. Heretofore, we have considered these to be embryonic, but they show apparent wear, and in other respects they are enigmatic, and at best, atypical. Tetrabelodon tusks proper, however young, are typical, and are obviously tusks in miniature. The tusks in doubt are of varying lengths and about the diameter of one's thumb, but taper backwards, are worn to a bluntly oblique point, and are slightly …

Hackberry Conglomerate A New Nebraska Rock, Erwin Hinckey Barbour

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

In the cabinets of the Nebraska State Museum are several excellent rock specimens, which at first sight pass for pisolite, which they simulate. Scrutiny shows that they are hackberry seeds in sand, cemented by lime and clay into a firm, compact rock. The term hackberry conglomerate seems apropos.

Notes On Nebraska Fulgurites, Erwin Hinckley Barbour

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

Some six or eight years ago the writer contemplated a study of Nebraska fulgurites, both in the field and in the laboratory. In the meantime however, it proves to be superfluous for, after supplying Mr. A. E. Anderson, of the American Museum of Natural History, with certain material and data he proceeded in a masterful way on a technical inquiry, and it is with pleasure that, although delayed in publication, his findings follow in Bulletin 7 of the Nebraska State Museum. The present paper will deal as briefly as possible with the mode of occurrence and gross structure.

Sand Fulgurites From Nebraska Their Structure And Formative Factors, Abram E. Anderson

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

So much has been written during the past century on the origin, structure and occurrence of fulgurites, or lightning tubes, found in many parts of the world that it would seem as though little remains to be added to the literature on the subject; but the discovery of a considerable number of unusually large and complete specimens in Holt and Stanton Counties, Nebraska, which exhibit remarkable definition of the particular features that have occasioned so much controversy regarding their formative processes, has added an important type to the representatives of this phenomenon and afforded clearer interpretation of the origin of …

Manganese Fulgurites, Harold J. Cook

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

During August, 1924, while doing reconnaisance work near the head of Chugwater Creek, Wyoming, on the ranch of Mr. J. L. Jordon, the writer's attention was called to some unusual and interesting specimens found in a limited area, perhaps an acre or so, on the slope of the small butte flanking the Chugwater Valley. The hills of the region are of Tertiary age, the particular spot under consideration being Oligocene, the Brule stage, or Oreodon beds.

Elephas Scotti A New Primitive Mammoth From Nebraska, Erwin Hinckley Barbour

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

On February 18,1922, the mandible of an unusually primitive mammoth was secured for the palaeontological collections of Mr. Hector Maiben by Mr. E. T. Engle. The specimen was found in Aftonian gravel on the farm of Mr. E. J. Hartman, five miles south of Staplehurst, Seward County, Nebraska. It is numbered 18-2-22 in the accession book of the Nebraska State' Museum.

Effect Of Various Factors On The Rate Of Reduction Of Zinc Ferrite, Calamine, And Willemite By Carbon, Foster Cary Nix

Masters Theses

"Zinc ores containing large amounts of ferric oxide, calamine and willemite have been known for a long time among practical zinc metallurgists to be more difficult to reduce than ores of the same type but free from the above named compounds. This has been thought to be due to the high temperatures necessary for the reduction of the zinc ferrite and the zinc silicates by carbon. The ferrite is formed both during the roasting of sulphide ores and during distillation in the retorts, while calamine and willemite are introduced as such in the ores. The amount of ferrite formed during …

A Study Of Phytosterol Obtained From Cocoa Beans And Cocoa Butter, Norman Anthony Pokorny

Bachelors’ Theses

Despite the fact that considerable work has been done on cholesterol, relatively little is known about its isomer, phytosterol. Both cholesterol and phytosterol belong to the general group of sterols. Cholesterol is described as an aromatic sterol, a mono~atomic secondary alcohol, containing an iso-propyl and a vinyl group, with a terpene-like structure. Cholesterol was first discovered by Conradi in 1775, then by Gren (1788) in biliary calculi. In 1785 Fourcroy isolated cholesterol from gall-stones, one variety of which is composed almost wholly of it, but it was confused with adipocere, until Chevreul (1814) discovered its true nature, when he declared …

Effect Of The Size Of Particles Of Zinc Ore And Carbon Upon The Rate Of Reduction Of Zinc Ore By Carbon, Keith Oxley Alexander

Masters Theses

"In the retort smelting of zinc ores one of the chief metallurgical problems is to obtain as complete a reduction of the zinc as is consistent with economical operation. Among the factors influencing the completeness of reduction are the temperature and time of distillation, the form in which the zinc exists in the ore, the form of carbon used as reducer, and the size of the particles or ore and reducer"--Introduction, page 1.

A Study Of Light Metals And Alloys At Low Temperatures, Donald E. Higgins

Historical Dissertations & Theses

Although the determination of the strength of metals and alloys at ordinary temperatures is an everyday matter, very little work has been done to determine their strength and elasticity at very low temperatures. Mallock and Schaefer have investigated certain metals at the temperature of liquid air, and have deduced formulae to express the relation between elasticity and temperature, while Andrade has given an expression for the flow of metals under large constant stress. This work was intended in part to find out if their formulae would apply to the very light alloys used here. Another object was to find, if …

The High School Algebra Situation From A College Standpoint, Dorris M. Stevens

Bachelors’ Theses

Mathematics as a high school and college course has been a much talked of subject in past years . For some time its opponents have exceeded its champions until it seems as though some explanation of the subject is necessary. For this reason this essay endeavors to make clear the object- methods and end in the study of mathematics , including especially high school Algebra and its effect on College Mathematics .

A Study Of The Vegetation Of Northeastern Arizona, Herbert Christian Hanson

University Studies (University of Nebraska) (1888–1984)

The State of Arizona is marked by a great series of cliffs that extend from the mouth of the Grand Canyon of the Colorado River in the northwestern part of the state southeastward into New Mexico. This line of cliffs, rising 1000 to 4000 feet above the desert plains forms the southwestern and southern boundary of the great physiographic province called the Colorado Plateaus. It is roughly circular and includes northeastern Arizona, northwestern New Mexico, western Colorado, and a large part of Utah. This province is subdivided by a number of deep canyons and high cliffs into numerous plateaus. The …

A Preliminary Report On The Nebraska State Museum, Erwin H. Barbour

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

The Nebraska State Museum has been established a sufficient number of years to make it widely known throughout the state, both by reputation and by personal visits. Incident to a growing clientele and an expanding correspondence, it is expedient that a concise circular letter be issued in bulletin form. Such a pamphlet can be promptly forwarded to inquirers and will offer obvious advantages over individual replies.

Diffraction And Interference Applied To The Reproduction Of Sound, Percy Martin Roope

Historical Dissertations & Theses

The diffraction and interference problems in sound are to a large extent those in light. However, in regard to a practical solution of problems, the analogy must not be carried too far. In light, in general, we deal with slits or circular openings, the dimensions of which are large in comparison with the wave lengths employed. On the other hand, in sound the openings thru which sound passes are sometimes large and sometimes small compared with the wave lengths. Many of the approximations made in the solution of problems in light cannot be made in sound.
