Water Erosion Control, L C. Lightfoot

Journal of the Department of Agriculture, Western Australia, Series 3

Although soil erosion caused by water action is common in our agricultural areas, effective erosion control measures, likely to pay for themselves quickly, can be applied in nearly every case. Plant cover above the soil surface, and fertile soil with good structures are the main factors which enable soils to resist erosion. Dense pasture gives the best cover and at the same time improves the fertility and structure of the soil both effectively and economically, so land management adjusted to the need and capability of soils, slopes and climate is of first importance. Contour practices are of secondary value and …

The Fluorescence Of Uranium In Solid Solution, Robert Emmett Kelly

Masters Theses

"The fluorescence of uranium finds its greatest application in the so-called "bead test" which is a method of qualitative analysis. In the form of a bead, the uranium is in solid solution, and if the proper chemical solvent is used, the bead will fluoresce under ultraviolet radiation.

In the systematic separation of the metallic elements, uranium is associated with the aluminum group in that it is not precipitated by hydrogen sulfide in 0.3 N H ion but is precipitated by ammonium hydroxide and ammonium sulfide. In the analytical scheme, uranium acts like beryllium. This process of detection is sometimes tedious …

Geochemical Prospecting Applied To The Illinois-Kentucky Fluorspar Area, Matthew Peter Nackowski

Doctoral Dissertations

"This study was completed to determine whether geochemical methods of prospecting could be applied to the search for fluorspar deposits in the Illinois-Kentucky fluorspar district.

During the course of the study, aspects of the geochemical cycle of fluorine under the climatic environment encountered were noted in the zone of weathering.

The Illinois-Kentucky fluorspar district supplies a large portion of the fluorite consumed in the United States. The producing deposits are of two geologic types. The vein deposits occur as nearly vertical tabular lenses or pods which occupy fractures. These deposits may reach the bedrock surface, but in any case, the …

Halogenated Epoxide-Phenol Reactions A Mechanism Study, Richard L. Rowton

Masters Theses

"The object of this investigation was to study the reactions of two other halogenated epoxides--namely, 3-bromo-1,2-epoxybutane and l-bromo-2,3-epoxybutane--with the phenolate ion, with the hope that the results obtained would shed additional light upon the mechanisms of such reactions. At the present time, no direct practical applications of the results can be forseen. However, the information gained will be a worthwhile addition to the vast existing store of knowledge already at our disposal, and might be of some help to future investigators"--Introduction, page 2.

A Study Of The Effect Of Jointing On The Blasting Of Granite, Graniteville, Missouri, Avery Ala Drake

Masters Theses

"Purpose of investigation: The purpose of this investigation is to attempt to determine the influence that joints exert upon the blasting of granite and if joints are induced by blasting. The problem grew out of an explosive evaluation project that was conducted by the Mining Department, Missouri School of Mines. In late May 1950, the project was moved into the granite area near Graniteville, Missouri. It became apparent upon study of this area that the jointing would have certain effects upon the results obtained. Dr. J. D. Forrester, Chairman, Department of Mining Engineering, Missouri School of Mines, Rolla, Missouri, suggested …

4-Benzoyl-4-Methyl-1, 2-Epoxypentane, An Attempted Synthesis, Robert L. Snell

Masters Theses

"The object of this research was to prepare first the simplest homologue of the epoxy-ketone considered by Russell to have been his product. If this homologue, 4-benzoyl-4-methyl-1,2-epoxypentane, could be prepared and caused to form a cyclic derivative of the type given by 1,4-diketones with 2,4-dinitrophenylhydrazone, the organic chemist would be given a new approach to substituted 1,2-diazines as well as a previously unreported reaction of the epoxide grouping. If this reaction could be made to occur, other epoxides of this series would be prepared and treated in the same manner.

It was decided that the shortest route to 4-benzoyl-4-methyl-1,2-epoxypentane would …

A Graphic Résumé Of The Pleistocene Of Nebraska (With Notes On The Fossil Mammalian Remains), C. Bertrand Schultz, Gilbert C. Lueninghoener, W. D. Frankforter

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

I T SEEMS desirable at this time to present a graphic resume of the Nebraska Pleistocene, together with a summary of the stratigraphic sequences of the fossil vertebrates. This report is based on data taken from various publications' in addition to information gathered by the present writers during the past fifteen or more field seasons. Intensive work has been done in the past five years in connection with recovery of paleontological material in the areas where government dams are under construction (Schultz, Lueninghoener, and Frankforter, 1948; Schultz and Frankforter, 1948; Holder and Wike, 1949). The information in the present paper …

Progress Report: Chemical Quality Of The Surface Waters In The Loup River Basin, Nebraska, John G. Connor

United States Geological Survey: Publications

The Loup River and its tributaries transport moderate amounts of siliceous minerals from the sand hills region of north-central Nebraska to the Platte River near Columbus, Nebr. Predominant chemical characteristics of these waters are a high percentage of silica, moderate hardness, and a low percentage of sodium. The composition of the Loup River water is influenced by the geologic formations through which ground water, a major contributor to the flows of the Loup River branches, has percolated. Investigation of water quality at or near proposed dam sites in the Loup River basin indicates that if soil and drainage conditions are …

Microfauna Of The Colorado Shale In The Sunburst Dome Area, Montana, Merle W. Emmert

Bachelors Theses and Reports, 1928 - 1970

It has been hoped that a micropaleontological study of the shales of the Upper Cretaceous Colorado Group in northern Montana would reveal certain faunal zones which would serve as markers in an otherwise drab, undifferentiated, 1800 feet of grey, fissile shale. This paper presents the results of a study of the microfauna in certain samples from this shale in the Sunburst Dome area north of Shelby, Montana.

The Elkhorn Mine Of Jefferson County, Montana, David D. Walker

Bachelors Theses and Reports, 1928 - 1970

In 1901, after yielding metals valued in excess of five million dollars, it was considered worked out. Since that time the mine has passed through the hands of several own­ers, none of whom have failed to realize a profit from it. Although at no time since its zenith did it ever regain its once great production, it did provide a livelihood for those who worked it. Now with the American Smelting and Refining Company interested in it, perhaps it will once again become an important producer.

The Occurrences Of Non-Metallic Minerals In Montana, Samuel T. Mitchell

Bachelors Theses and Reports, 1928 - 1970

This thesis is essentially an abstract of the literature concerning occurrences in Montana of minerals with a non-metallic luster. The dis­cussions give a general description of the occurrences of minerals as reported by the various references, but is not complete as less than 40 percent of the non-metallic minerals known to exist in Montana are discussed.

Sulphidizing Of Cerussite, Emil A. Kovacevich

Bachelors Theses and Reports, 1928 - 1970

The oxide minerals, such as cerussite, are not as amen­able to flotation as the sulphide minerals. Sulphidization is the usual means used today to increase the recovery of an oxide flotation; however, sulphidization under the most ad­vantageous conditions does not yield very satisfactory re­coveries.

Faunal Studies Of The Lower Jefferson Limestones, James L. Eymann

Bachelors Theses and Reports, 1928 - 1970

The exact geologic age of the Jefferson limestone in Montana has not been definitely determined, other than it is probably of upper, but possibly in part of middle Devonian age. Although not of immediate or apparent economic importance, the determination of the exact age of the Jefferson limestone may be of much value in connection with the discoveries of large quantities of oil in Devonian strata in the northern Great Plains and, in particular, with the extensive deep drilling in northeastern Montana which is anticipated during the summer of 1951.
