Rings With A Not Necessarily Transitive Order Relation, Lawrence Arnold Machtinger

Retrospective Theses and Dissertations

The main objective of this paper is the study of rings with a relation which has all the properties of an order relation on a ring except, perhaps, for one: transitivity. Consequently, many of the results presented here are generalizations of well-known facts about transitively ordered rings; and most, but not all, of the conclusions of this paper are applicable to such rings.

Effect Of Calcium Availability On Alfalfa Grown In Calcareous High Sodium Soils, Harry Irving Nightingale

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In soil science we shall always be confronted with reactions in soils that involve Ca. Early recognition of this led to experimentation in this area. Due to the fact that Ca deficiency is most common in acid soils, the majority of the experimentation has in the past been largely confined to acid soils and their soil-Ca-plant relationships. There has been relatively little research done with Ca and its availability problems associated with alkaline or sodic soils.

A Thermodynamic Study Of (1) Ligand Replacement Reactions And (2) The Interaction Of Hgcl[Subscript 2](Aq) With Hydroxide Ion, Ethylenediamine, Glycinate Ion, And Methylamine, Jerry Alvin Partridge

Theses and Dissertations

A method is reported for determining the species formed in solution by ligand replacement reactions. Reactions in dilute aqueous solution were studied in which the Cl^- on HgCl_2(aq) was replaced by hydroxide ion, ethylenediamine, glycinate ion, and methylamine. The species formed by the replacement reactions were established through computer analysis of pH titration data. Various reaction sequences were proposed for each system and log K values were calculated for each sequence. The selection of the correct reaction sequence for each system was based on the premise that only when the correct sequence is proposed will consistent log K values be …

Hydrogenation Of 4-Methylcinnoline, William E. Maycock

Theses and Dissertations

The rapid expansion of knowledge of cinnoline chemistry since 1941 has not included the hydrocinnolines. Not one catalytic hydrogenation of a fully aromatic cinnoline had been reported. This thesis is an effort to enlarge knowledge of this particular area of cinnoline chemistry. The work is a natural outgrowth of that done at Brigham Young University on decahydroquinoxaline, both the cis- and trans- isomers having been prepared and characterized. 4-Methylcinnoline, prepared by the method of Jacobs, et.al., was hydrogenated in neutral and acidic ethanolic solutions at 2000-3000 psig. hydrogen pressure and 100-266°. The catalysts used were 5% palladium on alumina, ruthenium …

Width Of Ion And Monopole Tracks In Emulsion, Robert Katz, J. J. Butts

Robert Katz Publications

The width of the tracks of ions in emulsion has been calculated from the assumption that a developable image is formed when the energy dosage deposited by delta rays exceeds a threshold value, here found to be 6000 ergs/cm² in G-5 emulsion. The theory agrees with measurements of track width obtained by projecting track images to a magnification of 3000× and tracing around their outline, while truncating isolated delta rays at their bases. Agreement is to within a grain diameter to a range of about 4 cm. From the theory we infer that there is no Z intelligence contained …

Marine Geology, Preston E. Cloud Jr.

Journal of the Minnesota Academy of Science

Were the average temperature of the earth a few tens of degrees less than it is, ice would be the most common crustal rock. The fact that it occurs in its liquid phase over 71 per cent of the earth's surface should not obscure the fact that the oceans are geologic features, particularly in their substructure, their boundary relations, and their history.

The Intentionality Structure Of Complementarity, Patrick A. Heelan

Research Resources

In this article Heelan argues that the return to the concrete and empirical implied in Heisenberg's insight on the importance of observables in physics was not, however, in Heisenberg's case, accompanied by a thorough re-thinking of the rationalist presuppositions of classical physics. The effect on Bohr, however, was to lead him to a complete rejection of rationalism and to the adoption of the contrary extreme, empiricism. The profound – though largely implicit – cause of the disagreement between Bohr and Heisenberg as to the correct interpretation of quantum mechanics, was resolved in the sumnler of 1927, by the common acceptance …

Miocene Mammals And Central American Seaways, Frank C. Whitmore Jr., Robert H. Stewart

United States Geological Survey: Staff Publications

The fossil mammal faunas of North and South America indicate that the two continents were separated from Paleocene or earlier time until the late Pliocene. Unfortunately our almost complete ignorance of the Tertiary land mammals of Central America, the geology of this large area, makes reconstruction of the Tertiary zoogeography of the region between the continents an exercise involving considerable speculation.

A History Of The War Service Land Settlement Scheme Western Australia, A, R. Barrett

Farm Systems and Economics published reports

In writing a history of the Western Australian War Service Land Settlement Scheme, it is pertinent to remark that land settlement projects have ever been difficult and, in fact, to date very few have been really successful. However, there has always been the necessity to accede to the desire of returning men to go on the land, also in States such as Western Australia there was and still is the need for further land development. Therefore, when the Commonwealth Government offered to provide the funds for servicemen's rehabilitation on the land the State gladly accepted and agreed to take responsibility …

The Discovery Of Quantum Mechanics, Patrick A. Heelan

Research Resources

In this chapter Heelan discusses how Heisenberg's insight of 1925, that physics should concern itself henceforth only with relations between observables, changed the intentionality-structure of physics. This insight led Heisenberg to the construction of a quantum mechanics of observables. Heelan briefly discusses the significance of his insighand of his rejection of Schrödinger's wave mechanics; the novelty of quantum mechanics as a physical theory, and the meaning he attributed to its most surprising result, viz., the Indeterminacy Relations. The crisis was a crisis of the rationalism inherent in the outlook of classical physics, and Heisenberg's insistence on "observable quantities" was a …

Derivation Of The Diffusion Equation And A Revision Of Matsuda's Theory For Polarography, W. Patrick Rahilly

Electronic Theses and Dissertations

Many theories have been proposed to yield a current-time relationship in Polarography. The most widely accepted is that of Matsuda. He assumes that the electrolyte can be separated into an inhomogeneous region about the mercury drop and a homogeneous region elsewhere. This assumption leads to a first order , nonlinear, ordinary differential equation directly solvable by substitution of a properly chosen series. But the series solution obtained is only a particular solution; for there exists, as one would expect, a family of solutions depending on a contrast of integration. In the literature, derivation of the diffusion equation has never been …

Birch Reduction Of Benzenesulfonamide And Benzenephosphonic Acid, Tony Ping-Fong Niem

University of the Pacific Theses and Dissertations

The use of an alkalai metal dissolved in liquid ammonia and a proton source such as alcohol to affect partial reduction of aromatic compounds, commonly known as the BIrch reduction, has proven to be a synthetic procedure of great utility. (1) The flexibility and usefulness of this reaction has attracted increasing attention in recent times, primarily by BIrch (1,2). The overall reaction occuring during the Birch reduction of benzene is indicated by Figure 1. [see PDF]

Birch has suggested that the reaction may proceed by the transfer of one electron to the aromatic nucleus to give a radical anion or …

The Binary Halides Of Molybdenum(Iv) And Tungsten(Iv) And The Oxochlorides Of Tungsten(Vi), Edward Roy Epperson

University of the Pacific Theses and Dissertations

It was the purpose of this study to investigate the reaction of molybdenum and tungsten dioxides with carbon tetrachloride and bromoform (via the method of Knox and Tyree) to produce anhydrous molybdenum and tungsten tetrachlorides and bromides and to determine whether the method is a reliable one for the synthesis of these compounds. Out of this grew an investigation into the preparation of the oxochlorides of tungsten(VI) using the same preparative technique.

The results of this study are here set forth. An attempt is made to systematize the published material on the synthesis and properties of the binary halides of …

Studies On The Conversion Of Indole Acetic Acid And Oxindole Acetic Acid By Hygrophorous Conicus, Barbara Ruth Patterson

Masters Theses

"The fungus, Hygrophorous conicus, produces the enzyme, indole acetic acid oxidase, when grown in the presence of indole acetic acid (IAA) or tryptamine. The IAA acts both as an inducer and a substrate for this intracellular enzyme. The product of the oxidation catalyzed by the IAA oxidase is oxindole acetic acid (OIAA). Since the IAA and OIAA absorb maximally at two different wavelengths the use of spectrophotometric analysis was possible for assaying for the IAA oxidase activity. Paper chromatography was used for qualitative identification of the IAA and OIAA. The rate of growth and the rate of formation of the …

Some Consequences Of The Decomposition Of Organic Matter In Lake Nitinat, An Anoxic Fjord, Francis A. Richards, Joel D. Cline, William W. Broenkow, Larry P. Atkinson

CCPO Publications

Observations in Lake Nitinat, an anoxic fjord on Vancouver Island, British Columbia, indicate that the large accumulations of ammonia, carbonates, phosphates, silicates, and sulfides in the deep water are the result of oxidative and fermentative decomposition of organic matter of planktonic origin, the reduction of sulfate ions, hydrolytic or other non-oxidative release (in the case of silicates), and the solution of carbonates (which also increases the alkalinity). Ammonia, sulfides, and silicates accumulate in the sulfide zone in direct proportion to each other, but some of the phosphate is probably released from the organic matter earlier than the other components, and …

Wheat Quality Surveys In Western Australia. 2. Variation Between Seasons And Localities In The Production Of High And Low Protein Wheat, J A. Parish

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

Although the protein content of West Australian f.a.q. wheat averages only 9.4 per cent., often substantial amounts of comparatively high protein wheat are contained in this mixture.

However the quantity varies widely from year to year and is obtained from widely scattered areas of the wheatbelt.

Comparison Of Methods To Select A Probability Model, Howard Lyndal Colburn

Masters Theses

"A comparison is made between the estimates of the parameters in a gamma distribution obtained by the method of moments with those obtained by a numerical approximation to the maximum likelihood estimates. The estimates obtained by the numerical approximation had a smaller mean squared error from the true value than the estimates obtained by the method of moments. Modifications to tests of fit are made in order to develop methods to select a distribution from a set of possible distributions for a population with an unknown distribution. These selection methods are compared in their ability to make correct selections. Although …

A Study Of Certain Conservative Sets For Parameters In The Linear Statistical Model, Roger Alan Chapin

Masters Theses

"In the case of the linear statistical model, it has been shown that under certain conditions the confidence intervals obtained by considering the parameters one at a time are conservative when used as a joint confidence region, using the product of confidences as the confidence. However, nothing had been known of how conservative they are. This research provides accurate estimates of the true confidence for these cases.

Also, it has not yet been proved that they are indeed conservative for all cases. It is thought that they are, and the results of this research support this conjecture"--Abstract, page ii.

An Instrument For The Measurement Of Anelastic Properties Of Glass, Thomas Frederick Miller

Masters Theses

"An inverted torsion pendulum for measuring the internal friction and dynamic shear modulus of glass fibers over an extended temperature range has been constructed and calibrated. The calibration consists of the determination of the moment of inertia. Extraneous damping losses were investigated and primary sources were found to be (1) the suspension thread, (2) the method of securing the fiber and (3) air damping. Anelastic measurements were made on an annealed vitreous silica fiber and a soda-lime-silica fiber"--Abstract, page ii.

Polarography Of Selected Metal Ions In Anhydrous Aliphatic Diamines, Frederick William Foss Jr.

University of the Pacific Theses and Dissertations

A search of the literature revealed that no study has sought to measure and compare the polarographic solvent properties of the anhydrous aliphatic diamines. In fact, there has been no reported instance of the use of anhydrous 1,3-propanediamine or 1,4-butanediamine in any electro- chemical system.
