Geology Of The East-Central Portion Of The Nelson Quadrangle, Clark County, Nevada, Tedral Kantor

Masters Theses

"The purpose of this investigation was to determine the unusually complex geology of a little-known area south of the Eldorado mining district, southern Clark County, Nevada. The area, mapped at a scale of 1:24000, comprises a segment of the northerly-trending Eldorado mountains in the southeast corner of the Great Basin. This rugged desert area is on a drainage divide between the Great Basin and the Colorado River. The rocks of the area consist of Precambrian gneisses and schists invaded by successive generations of Upper Cretaceous (?) - Tertiary igneous rocks. The older rocks, mainly biotite-chlorite gneisses, have resulted from high-grade …

Fall Food Habits Of The Merriams' Wild Turkey In Western South Dakota, Curtis Martin Twedt

Electronic Theses and Dissertations

The several varieties of wild turkey (Meleagris gallopavo) formerly ranged over much of what is now eastern, central and southwestern United States. A large portion of the species habitat was destroyed by logging and by clearing forest land for agricultural use. Wild turkey population, were also directly decimated because of bunting by early settlers. Edminister (1954) estimated present Wild turkey range to be approximately 1 per cent of the historic range. In the past few decades, wild turkey population have increased to the point where the species has begun to assume a prominent place among the game birds. . . …

Coordination Of 2, 8- Bishydroxymethyl - 2, Elements Of The First Transition Series, Charles Edward O'Rear

Master's Theses

The preparation and study of 2, 8-bishydroxymethyl-2, 8-dimethyl-3, 7-diaza-1,5,9-nonanetriol with ions of the first transition series have been investigated. Spectrophotometric studies of solutions of this compound with Cu(II) and Ni(II) ions gave evidence of the formation of complexes containing one mole of ligand per metal ion throughout a wide pH range. The Cu(II) complex, the yellow colored Fe(III) complex formed at high pH, and the light blue colored Ni(II) complex have remained stable over several months. The red colored Ni(II) complex changes slowly into a more stable greenish-yellow complex. The ligand formed weaker complexes with Co(II) and Mn(II). Data from …

An Investigation Of The Analysis Of Turpentine By Gas Chromatography, John R. Wagner

Master's Theses

The development of gas chromatography and the publication of data on terpene analysis by this method has lead to this attempt to analyze turpentine by gas chromatography. The work has been limited to Gum Spirits of Turpentine and Steam Distilled Wood Turpentine since these are of chief importance and are the only types commonly retailed in small packages.

There have been three objectives:

1. To develop a method based on gas chromatography for distinguishing between Steam Distilled Wood Turpentine and Gum Spirits of Turpentine, and detection of mixtures and adulteration.

2. To identify as many components of the two turpentines …

Determination Of Minimum Lethal Level Of Toxaphene As A Piscicide In Lakes Of North Dakota, Dale L. Henegar

Electronic Theses and Dissertations

Toxaphene as a piscicide for localized field application has not been widely used because minimum lethal concentrations have not been in the field. There is, however, considerable information gained from laboratory bio-assay studies (Surber, 1498; Duedoreff, et al. 1953; Hooper and Grzenda, 1955, et al. 1959). Concentrations indicated by such studies are not necessarily correct for field use. Prevost (1960) pointed out that results from controlled laboratory experiments do not always yield dosages exhibiting similar results in the field where a number of variables, both known and unknown, exist over which the field worker has little or no control.

A Theoretical Investigation Of Periodic Precipitation, Jack M. Scrivner

Masters Theses

"The problem of periodic precipitation in solution or gel is considered from the standpoint of supplementing the simple diffusion equation with chemical reaction rate terms. This addition has the effect of making the differential equations of the process non-linear.

The system of equations admits of a periodic, steady-state solution under certain conditions, but lack of experimental values for the parameters prohibits a definite statement as to whether or not the model is valid"--Abstract, page ii.

Minor Elements Can Be Overdone, L T. Jones

Journal of the Department of Agriculture, Western Australia, Series 4

T H E term "minor elements" which is now commonly used and well understood by farmers and gardeners, refers to the five essential plant foods—copper, zinc, manganese, molybdenum and boron.

These five essential plant foods are needed by all plants in minute quantities and it is relatively easy to use them in excess of actual requirements or even in toxic amounts.

In practice this is not usually a problem with cereals and pastures. The important exception is when zinc alone is added to a cereal crop low in copper and the extra zinc accentuates the copper deficiency, and poorer yields …

Manage Your Rainfall For Maximum Production, J E. Watson

Journal of the Department of Agriculture, Western Australia, Series 4

TTOW much would an extra inch of rainfall be worth to you? Much sloping land loses this much and more by run-off every year.

The soil is the main asset of your farm, but your profits depend on how you manage the rain which falls on it.

Microorganisms And Soil Structure, T. M. Mccalla, F. A. Haskins

Department of Agronomy and Horticulture: Faculty Publications

SUMMARY

Good stable soil structure is valuable for promoting the growth of plants and micro-organisms by permitting enhanced aeration and water penetration and by decreasing erosion under some conditions.

Micro-organisms influence water percolation through the soil. They may plug up soil pores with byproducts of growth and reduce water percolation. On the other hand, if a soil containing a large amount of microbial products is stirred and allowed to dry, then the percolation may be high.

Micro-organisms are involved in stabilizing soil structure by their products of decomposition and their cellular binding material, such as mycelia. Microorganisms differ greatly in …

The Magnetic Monopole, Thomas E. Kemple

Masters Theses

"Since Dirac has shown that the concept of a magnetic monopole follows from the fundamental laws of quantum mechanics and that it imposes quantization of electric charge, one has reason for taking the magnetic monopole seriously. Such particles, if they exist, would also give symmetry to Maxwell's equations.

A comprehensive review of the literature is presented and all known properties of magnetic poles are discussed. Scattering of mono- poles by heavy nuclei is analyzed in detail and definite mathematical relations are established. All previous experimental work known is outlined and discussed. Definite criteria for identification of monopole tracks in a …

An Experimental Investigation Of Coloring Matter In Canna Indica Flowers, James Clinton Vogt

University of the Pacific Theses and Dissertations

The research was carried out for the purpose of isolating and identifying the coloring matter in flowers of the canna indica (canna lily) variety. It was done by extracting the pigment from flower petals with methanol, amyl alcohol, and other solvents, and crystallizing the pigment as a salt. Physical properties such as solubility, color reactions, spectra and others were examined for this pigment. Chemical properties and degradation products were also examined in order to identify the chemical structure of the pigment.

The Surficial Geology Of Southern Logan County, North Dakota, John W. Bonneville

Theses and Dissertations

Southern Logan County, North Dakota, was glaciated at least three different times during the Pleistocene epoch. Scattered patches of highly weathered iron-cemented drift found in the area of eroded Cretaceous bedrock in southwest-era Logan County are very possibly pre-Wisconsinan in age. Two younger drift sheets of Wisconsinan age cover the remaining portion of the county. One of these drifts, the Napoleon drift, is probably early Wisconsinan, and the other, the Burnstad-Streeter drift, is likely late Wisconsinan in age.

A great diversity in types of glacial topography and individual features is found in southern Logan County. Excellent examples of end moraine, …

Identification Of The Products And Mechanism Of Decomposition Of Thiazate, Paul Edward Williams

University of the Pacific Theses and Dissertations

This work is an additional facet of the research undertaken by Dr. Herschel Frye of the Department of Chemistry of the University of the Pacific while he was a graduate student at the University of Oregon. Frye succeeded in making an analytical reagent for zinc and other transition metals similar to dithiszone but water soluble. His approach was to to sulfonate the benzene rings thus giving water solubility because of the ionic nature of the sulfonic acid. The new reagent-tensed thiazate--was quite successful in its purpose, but the sections of the compound were somewhat different than dithizone. The purpose of …

Evaluation Of The Force Constants Of Non-Polar Gases From Viscosity Data, Kei-Sin Wei

Masters Theses

"The analytical expressions for the transport coefficients (i.e. viscosity, thermal conductivity, and diffusivity) of an ideal gas can be derived from the kinetic theory of gases. It is also possible to make these analytical expressions adequate for real gases if the intermolecular forces of attraction and repulsion for these gases have been taken into consideration.

The intermolecular forces have been studied by many investigators. The Lennard-Jones potential is one of the most realistic semi-empirical statements which represents particularly the intermolecular forces of attraction and repulsion for non-polar gases.

The values of the Lennard-Jones potential parameters or the force constants of …

A Proposal For The Use Of The Method Of Characteristics As A Condition On The Numerical Solutions Of Two-Dimensional Lagrangian Isentropic Flow, Christian D. Anderson

Physics & Astronomy ETDs

The method of characteristics has been widely used in two- dimensional problems (i.e., one spatial dimension and time or two spatial dimensions for the steady state), and it was felt that this method, in all or part, could be applied to time-dependent, two- space hydrodynamics.

In this paper we have done the following:

1. Derived the two-dimensional, time-dependent, nonviscous Lagrangian Equations;

2. Discussed, in general, some aspects of the method of characteristics;

3. Applied the method to our Lagrangian equations; and finally,

4. Proposed a possible application of our results to the numerical solution of the Lagrangian equations.

The Determination Of Ethanol In Aqueous Solution By Gas-Liquid Partition Chromatography, Robert L. Morrison

University of the Pacific Theses and Dissertations

The present chemical and physical methods for the determination of ethyl alcohol are all subject to systematic errors derived from any of a number of interfacing substances usually present in solution with the ethanol. Some of the most popular methods are slow and tedious and require a good deal of skill and technique to perform. The dichromate (2), pycnometer and refractometer methods are three such methods. The interfering substances most often present in industrial and food products are fusel oils and acetaldehyde. These substances interfere in the three methods just mentioned. It is of course possible to analyze for these …
