Economic Analysis Of Forage Production And Utilization In Dakota And Dixon Counties, Nebraska, Howard W. Ottoson

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Soil erosion remains a serious problem on many Nebraska farms despite programs of financial assistance, technical aid, and education by several national and state agencies. One reason that soil conserving adjustments in land use have not been made by farmers is that considerable uncertainty surrounds the economics of soil erosion control on the farm level. This study is an attempt to increase knowledge and reduce some of the uncertainty with regard to the economics of erosion control in a specific area.

Studies In Quantitative Paleontology. Iii. An Application Of Sequential Analysis To The Comparison Of Growth Stages And Growth Series, Benjamin H. Burma

Department of Earth and Atmospheric Sciences: Faculty Publications

Detailed directions for carrying out a comparison of characters of fossils by a sequential analysis are given. The method is adapted to comparison at a single growth stage and to the comparison of growth series. The method has the advantage of, in general, requiring fewer specimens than the classical methods of comparison.

A Colorimetric Coulometer, Clayton C. Roth

Master's Theses

In the study of many electrochemical processes, such as, surface adsorption on electrodes, a simple, rapid, and relatively accurate coulometer that will measure .01 to 1.0 coulombs, would be extremely useful. This project was commenced to investigate the feasibility of an entirely different approach for coulometric analysis for application in this range.

This new type of coulometer utilizes a colorimeter for determining the amount of coulombs passed through coulometer cell. Consequently, any electrode process which of its own nature is color-producing, or a process which, in turn, can actuate a color indicator, is a potential reaction for this colorimetric couloumeter.

A Statistical Evaluation Of Various Determinations Of Germanium, Kenneth William Bartz

Bachelors’ Theses

Germanium first came to the author's attention under the heading of "A Study of the Excited States of Matter." The various and diverse, not to mention peculiar properties of this element aroused my interest. But upon further studying of this unusual element my concern switched from its properties to the methods of analysis. It is the purpose of this paper to discuss and correlate the numerous and varied analytical determinations. However, actual determinations are limited to instrumental procedures only.

For the evaluation and interpretation of the date, Statistical Analysis is used. The author's qualification in Statistical Analysis include a year …

Mechanism Of Adsorption Of Cations By Silicate Minerals, Milton Glen Armstrong

Theses and Dissertations

Adsorption of cations by clays has been a subject of investigation for many years. Many proposals have been advanced to explain this process of adsorption. Two proposals have been prominent in recent years. The Marshall "charged lattice" theory attributes adsorption of cations by clays to an electrostatic attration of the clay particles for cations. This charge on the clay particles is attributed to various isomorphic substitutions in the lattice of the clay which result in an unbalanced charge on the particle. This isomorphic substitution can take place either in the silicon-oxygen tetrahedra of the silicate structure or with the aluminum …

On The Continuity Of The Real Roots Of An Algebraic Equation, Melvin Henriksen, John R. Isbell

All HMC Faculty Publications and Research

It is well known that the root of an algebraic equation is a continuous multiple-valued function of its coefficients [5, p. 3]. However, it is not necessarily true that a root can be given by a continuous single-valued function. A complete solution of this problem has long been known in the case where the coefficients are themselves polynomials in a complex variable [3, chap. V]. For most purposes the concept of the Riemann surface enables one to bypass the problem. However, in the study of the ideal structure of rings of continuous functions, the general problem must be met directly. …

The Construction And Operation Of A Universal Specimen Mount With Protective Lead Shield For The Purpose Of Determining Pole Figures Using The Schulz-Decker Transmission Technique, Richard L. Fausner

Bachelors Theses and Reports, 1928 - 1970

It was the purpose of this study to construct a universal mount, to construct a protective lead shield, to operate the instrument, and to provide a pole figure using the transmission method of Schulz and Decker. There are at present several lengthy x-ray methods of determining the grain orientation of metals. These methods are mainly photographic. In order to provide a rapid means of obtaining the necessary information concerning the grain orientation of a metal, a universal mount was constructed.
