Missourian Triticites Of The Northern Mid-Continent, Benjamin H. Burma Nov 1942

Missourian Triticites Of The Northern Mid-Continent, Benjamin H. Burma

Department of Earth and Atmospheric Sciences: Faculty Publications

The tendency toward fine discrimination in fusulinid species has made necessary standardization in their study. Theories and practices of fusulinid study are herein discussed in some detail. Four new species of Triticites are described from the Missouri series of the Pennsylvanian system; one species from the Virgil series and two froim the Missouri are redescribed, and the characters of the other five known Missourian species from the northern mid-Continent are shown in graphs, thus bringing together the known Missourian species. Finally consideration is given to the ontogeny and phylogeny of the group.


Micro-Density Determinations Of Liquids, Rachel L. Horowitz Sep 1942

Micro-Density Determinations Of Liquids, Rachel L. Horowitz

Bachelors’ Theses

Recent developments in the field of microchemistry have aroused the necessity of accurate micro-methods for density determinations. Such methods have been developed by various investigators and some of them found their application in re­ search and industry, wherever the saving of material and time was an essential problem.

The purpose of this work is to compare all the methods of micro-density determinations found in literature, check their accuracy and simplicity and find their limitations and advantages.


The Effect Of The Ph On The Viscosity Of Various Gelatin Solutions, Theodore C. Kraus Aug 1942

The Effect Of The Ph On The Viscosity Of Various Gelatin Solutions, Theodore C. Kraus

Bachelors’ Theses

Tremendous research has been done in recent years In the field of the protein colloids. Our small, but nevertheless important knowledge of the protein colloids is due to such eminent investigators as Loeb, Kruyt, Freundlich, and Hardy, to name only a few. They have presented to the scientific world valuable experiments and reports of their work. However, much remains to be accomplished in spite of their achievements. The fact that the whole of the organic life processes concerns Itself with colloidal phenomena, particularly the reactions of large aggregates of protein particles, is indicative that the field is widespread in its …


Vegetation Of The Northern Part Of Cherry County, Nebraska, William L. Tolstead Jul 1942

Vegetation Of The Northern Part Of Cherry County, Nebraska, William L. Tolstead

Conservation and Survey Division: Faculty and Staff Publications

Agricultural practices in the Great Plains of North America are now in a period of adjustment from a traditional agriculture initiated by pioneer farmers to a grazing economy based upon potentialities of climate and soil. The attainment of a proper system of land use has been retarded in many localities by the lack of definite information concerning the vegetation and its indicator significance. In this study of the vegetation of Cherry County, Nebraska, the interrelations between the plants and their environments are discussed, the dominant species are described, and changes in grasslands caused by seasons, grazing, and climatic cycles are …


A Research In Sixth Grade Children's Solution Of Verbal Arithmetic Problems, Herbert Schroder Jun 1942

Physical And Chemical Properties Of Soil Profiles Of The Scott, Fillmore, Butler, Crete, And Hastings Series, Henry W. Smith, H. F. Rhoades

Nebraska Agricultural Experiment Station: Historical Research Bulletins

For the studies reported here most of the samples were taken in the spring of 1940 from the walls of deep pits dug in areas previously selected by surveyors and inspectors as type locations for the Butler series. To elucidate certain points, samples were taken from the upper part of several other profiles, also called Butler, the following year. In addition to this work on the characterization of the Butler series, further data have been collected concerning soils of the Scott, Fillmore, Crete, and Hastings series. Profile samples were obtained from type locations of each of these series. The data …

An Experimental Investigation Of The Age Hardening Of Nickel With Boron, Willard M. Boam

Bachelors Theses and Reports, 1928 - 1970

Since 1911, at which time, the age hardening phenomenon of duralumin was discovered by Film, much re­search has been carried on investigating the various alloy systems. The successful application of age hardening to the copper aluminum system (duralumin) has indicated the possibility of hardening practically all the metals in the same way.

An Investigation Into The Recovery Of Indium From Fume Residue, Emery J. Turner May 1942

An Investigation Into The Recovery Of Indium From Fume Residue, Emery J. Turner

Bachelors Theses and Reports, 1928 - 1970

Several months were required to produce a single gram of indium. Consequently, the industrial history of the metal is extremely short. In view of the unique properties that indium has demonstrated in this short period, it is probable that indium is still in its early stage of development. However, the commer­cial applications of the metal are well established and indium is now produced on a commercial scale. It is obtainable as the metal or in solution for electroplat­ing.


Some Leaching Characteristics Of The Butte Rhodochrosite, W. L. Slosson May 1942

Some Leaching Characteristics Of The Butte Rhodochrosite, W. L. Slosson

Bachelors Theses and Reports, 1928 - 1970

With the increasing importance of manganese in the metallurgical fields of today and tomorrow, ex­tensive work along the lines of its successful ex­ploitation has been accomplished by many investiga­tors. Since tie current world situation has shut off most of our supply of high-grade manganese ores from foreign sources, the low-grade domestic deposits have entered the fields of investigation very rapidly.


The Effects Of Some Percentages Of Nickel On The Annealing Of Cartridge Brass, A. Edward Zezula May 1942

The Effects Of Some Percentages Of Nickel On The Annealing Of Cartridge Brass, A. Edward Zezula

Bachelors Theses and Reports, 1928 - 1970

The most important element in the alloying of steels, has also been used quite extensively as a third constituent in copper-zinc alloys. The chief characteristics of nickel which make it desirable as an alloying element are its toughness, high strength, and resistance to corrosion.
