Biological Oxidation Of Copper Sulfide Minerals, Delmar Boyd Davis
Biological Oxidation Of Copper Sulfide Minerals, Delmar Boyd Davis
Theses and Dissertations
This work represents a study of the biological oxidation of copper sulfide minerals. The principal objective of the study was to determine the extent of bacterial oxidation on copper containing sulfide minerals. It was also desired to determine if the bacteria could oxidize copper sulfides in the absence of iron. A better understanding of the nitrogen requirements of the organisms was desired. Minerals used in this study were Bingham Canyon Float Concentrate, chalcopyrite, covellite, calcocite, bornite, tetrahedrite, and reagent grade copper sulfide. The bacteria used were obtained from the mine waters of Bingham Canyon, Utah. To study the problem the …

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
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
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
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 …
