Kimberley Soils Need Phosphates, W. M. Nunn
Kimberley Soils Need Phosphates, W. M. Nunn
Journal of the Department of Agriculture, Western Australia, Series 3
Research work carried out at the Kimberley Research Station on the Ord River, and on experimental plots throughout the East and West Kimberleys, indicates that the soils of the Kimberleys are quite as deficient in phosphorus as are the soils of our agricultural areas where superphosphate is essential to the growth of most crops.
This may come as a surprise to many people, for there has been a widespread tendency to assume that the Kimberleys soils, especially those of the Ord and Fitzroy valleys, are highly fertile.
The black earths of Queensland's Darling Downs produce most enviable yields of sorghum …
Sunrise And Sunset Times For March-April 1952
Sunrise And Sunset Times For March-April 1952
Journal of the Department of Agriculture, Western Australia, Series 3
Times of sunrise and sunset for every fifth day, are given for a number of towns throughout the State. Times for a town not on the list may be estimated if its position in relation to one or more of the listed towns is known. The times given for sunrise are those of the first appearance of the top edge of the sun over a true horizon; those for sunset give the time of the sun's disappearance below a true horizon. Situation in a valley would make the sun appear to rise later, and on a hill it would appear …

The Fluorescence Of Uranium In Solid Solution, Robert Emmett Kelly
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 …
On The Ideal Structure Of The Ring Of Entire Functions, Melvin Henriksen
On The Ideal Structure Of The Ring Of Entire Functions, Melvin Henriksen
All HMC Faculty Publications and Research
Let R be the ring of entire functions, and let K be the complex field. The ring R consists of all functions from K to K differentiable everywhere (in the usual sense).
The algebraic structure of the ring of entire functions seems to have been investigated extensively first by O. Helmer [1].
The ideals of R are herein classified as in [2]: an ideal I is called fixed if every function in it vanishes at at least one common point; otherwise, I is called free. The structure of the fixed ideals was determined in [1]. The structure of the …
A Study Of The Effect Of Jointing On The Blasting Of Granite, Graniteville, Missouri, Avery Ala Drake
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 …
Audio Census Of Some Wisconsin Game Birds, Donald R. Thompson, Charles W. Lemke
Audio Census Of Some Wisconsin Game Birds, Donald R. Thompson, Charles W. Lemke
Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts
Audio censuses of Wisconsin game birds were commenced in 1948, and now include the bobwhite quail, the pheasant and the ruffed grouse, in the order in which censuses were introduced.
Briefly, audio censuses are based on the characteristic sounds given by the male of the species concerned during the breeding season. An observer strategically located at a station, or stations in the field tallies the number of individuals calling, and/or the number of calls heard during a given time period.
In Wisconsin, only the transect method is used, with the observer following a given route and making listening stops of …
Insect Types In The Collections Of The University Of Nebraska State Museum, Martin H. Muma
Insect Types In The Collections Of The University Of Nebraska State Museum, Martin H. Muma
Bulletin of the University of Nebraska State Museum
In 1948 the insect collections at the University of Nebraska State Museum were placed in the care of the author. Prior to that date curatorial duties were assumed or assigned to full time teaching or research staff members. As would be expected under the latter circumstances, the organization of study material and types was neglected in many families and genera. Since 1948 type material, because of its intrinsic value, has received considerable attention. All primary and representative secondary types have been assembled in three museum cases and one slide cabinet for curatorial and study convenience.
Montan Wax From California Lignites, Robert John Kvick
Montan Wax From California Lignites, Robert John Kvick
University of the Pacific Theses and Dissertations
Montan wax has been extracted from the lignite deposits of Germany since the early part of the twentieth century, The wax was named by von Boyen (1901), The word Montan is derived from the Latin term montanus meaning "of a mountain," The wax has found extensive uses in polishes, insulating materials, candles, explosives, and special applications in the rubber industry, The increased demand for waxes for industrial uses and the limited supply of domestic origin has made the study of the sources and characteristics of domestic waxes desirable, California lignite has been shown to be a valuable source of Montan …

Urea Adducts Of The Esters Of Stearic Acid, Paul Elliott Greene
Urea Adducts Of The Esters Of Stearic Acid, Paul Elliott Greene
University of the Pacific Theses and Dissertations
Urea forms crystalline complexes with n-alkanes and their liner derivatives but not with most branched and cyclic hydrocarbons and their derivatives. The compounds are stable enough to be used in separating these types of aliphatic compounds from their branched and cyclic analogs. Linear esters derived from normal saturated acids give adducts as expected. Urea complexation was found to be of great importance in the purification and separation of unsaturated esters of high molecular weight.
The object of the present research was to investigate the compositions of urea adducts of various long-chain esters, approaching the class of waxes, to test various …

The purpose of this paper is to investigate three California oaks as possible sources of tannin. Even though the study of the three varieties of tree may not be representative samples, the procedures developed may prove to be valuable in a more extensive research by other workers.
Geochemical Prospecting Applied To The Illinois-Kentucky Fluorspar Area, Matthew Peter Nackowski
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 …
A Linear Polymer X-Ray Scattering Model, Bernard Cohen
A Linear Polymer X-Ray Scattering Model, Bernard Cohen
Masters Theses
"In the development of X-ray scattering intensity curves physical models are necessary for the theoretical mathematical development involved. The purpose of this paper is the development of a physical model suitable for X-ray diffraction analysis or a linear polymer.
X-ray intensity patterns may be used to give a greater insight as to the atomic structure, configuration or atoms, molecular weight, and therefore a greater knowledge of the structure of matter, both microscopic and macroscopic. The converse may sometimes be used. An atom or molecular model is constructed, from this model X-ray scattering curves may be derived. These curves may be …

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