The Electrolytic Reduction Of Osmium Tetroxide In Perchloric Acid Solution, Donald Lloyd Brunner

University of the Pacific Theses and Dissertations

This is a study involving some of the chemistry of osmium tetroxide in perchloric acid solution. The research was originally instigated from a seminar report on the ruthenium III thiocyanate complex ion which was studied in perchloric acid solution. The seminar report given by Craig Townsend discussed how a spectrophotometric study by Yaffe and Voight (1951) was made of the ruthenium III thiocyanate complex ion, Similar possibilities were recognized as being possible in attacking the problem of an osmium thiocyanate complex or complexed. Some of the chemistry involved in the study of the ruthenium III thiocyanate complex will be discussed …

A Syllabus For A Course In Analytical Projective Geometry, Herbert Richard Warne

University of the Pacific Theses and Dissertations

Projective geometry: a boundless domain of countless fields where reals and imaginaries, finites and infinities, enter on equal terms, where the spirit delights in the artistic balance and symmeric interplay of a kind of conceptual and logical counterpoint, - an enchanted realm where thought is double and flows throughout in parallel stream.

Evaluation Of Sprinkler Irrigation Systems In Northern Utah, Jay M. Bagley, Wayne D. Criddle

Reports

Summary and Conclusions: Sprinkler irrigation will continue to expand in Utah as well as in other irrigated areas of the world. This method of irrigation is suitable to all farm crops grown in the state and to most soils. It is particularly adapted to steep foothill areas where the water supply can be obtained at higher elevation and pumping is not necessary to develop pressure for the sprinkler systems. Also, much of the irrigated land of the state, particularly along the Wasatch front, is owned and operated by "part-time" farmers. Having the water under complete control and the irrigation schedule …

A Study Of The Emission And Absorption Spectra Of Nacl And Kcl Between 100 A And 1000 A, Paul Henry Blackmon

Masters Theses

"This investigation was begun with the idea of obtaining the emission and absorption spectra of NaCl and KCl in the region between 100 A and 1000 A. From these data, it is hoped that useful information concerning the energy levels of these two substances may be obtained.

The vacuum ultraviolet region is rather difficult to investigate because of the necessity of removing all air, lenses and other absorbing material from the light path. Many writers have enumerated the problems involved and some have indicated that much work still needs to be done in the vacuum ultraviolet.

In order to do …

Geology Of The South Half Of The Meramec Spring Quadrangle, Missouri, Howard Joseph Yorston

Masters Theses

"This report is a continuation of the work initiated by Mueller in his mapping of the north half of the Meramec Spring Quadrangle. The completion of this work provides not only a geologic map of the whole quadrangle but also completes the mapping of the geology of a strip of quadrangles extending from Rolla to the Mississippi River. In addition to being a step closer to the goal of complete geologic coverage for the state, this work will be of value to those concerned with the prediction of depths of wells drilled in search for water, which in view of …

Foraminifera Of The Type Section Of The Archusa Marl Of Mississippi (Eocene, Claiborne Group, Wautubbee Formation), Nathan Eugene Crockett

Masters Theses

"The type locality of the Archusa marl member of the Wautubbee formation is situated south of Quitman, Clarke County, Mississippi. Stratigraphically, the unit falls within the middle Eocene Claiborne group, being roughly equivalent to the upper part of the Lisbon formation of Alabama and the lower part of the Cook Mountain. The marl falls within the Ostrea sellaefonnis zone and the zone of "Ceratobulimina eximia.” The type section consists of 48 feet of sandy marls, with a thin oyster bed near the middle.

The Archusa foraminifera fauna consists of 87 species and varieties, belonging to 49 genera and …

Determination Of The Thermal Conductivity Of Sodium Chloride At Elevated Temperatures, Harold Robert Weisbrod

Masters Theses

"The purpose of this research is to investigate possible methods of determining the thermal conductivity of small poorly conducting samples at elevated temperatures, and, further, to assemble a suitable apparatus, followed by measurement of thermal conductivity of one or more cubic lattice samples.

Basic requirements of the apparatus are few. It is first required that the measurement of thermal conductivity be made over a considerable range temperature. It is also preferred that the basic apparatus be placed in a vacuum where undesirable heat flow by convection is eliminated and air corrodible samples are preserved.

The apparatus must use only the …

Coloration Of Glass By High Energy Radiation, Thomas L. Nickens

Masters Theses

"Purpose of Investigation: One of the objects of this investigation is to determine the amount of CeO₂ required to prevent the discoloration of glass when exposed to gamma radiation. By discoloration, it is meant that there has been a change in the absorption bands of visible light. Another objective is an attempt to prevent the coloration by the introduction of two oxides not previously used. Finally, a theory is presented which could explain why glass containing CeO₂ does not change color upon irradiation by gamma rays"--Introduction, page 1.

A Model For X-Ray Scattering From A Free-Volume Liquid, Charles A. Hewett

Masters Theses

"Investigation of the diffraction of x-rays by liquids was begun soon after the well-known work of Friedrich, Knipping, and Laue proved to be of value in supplying information as to the arrangement of atoms in crystalline matter. Friedrich in 1913 reported x-ray diffraction patterns of Canadian Balsam, paraffin, and amber; three years later Debye and Scherrer, in their work on benzene, (among other liquids investigated) showed that the diffraction phenomenon exhibited was one of interference. Still later, in 1922, Keesom and de Smedt reported similar investigations carried out on argon, nitrogen, and oxygen in the liquid state, the results of …

The Velocity Of Ultrasonics In Liquids, Mack A. Breazeale

Masters Theses

"In acoustics the term ultrasonics is used to refer to those frequencies which are above the range of human hearing; that is, frequencies above approximately 20,000 cycles per second. Since the laws of sound which are valid for the audible range are also valid in the ultrasonic range and since the wave length of ultrasonics is much shorter than that of audible sound, ultrasonic has proved very valuable in the calculation of both the velocity and the absorption coefficient of sound in various media. This is especially notable in the case of liquids, where the velocity of sound is much …

The Mineralogy Of The Grassy Creek And Saverton Formations, Dirk Pieter Van Duym

Masters Theses

"A study of the mineralogy of the Grassy Creek and Saverton formations of Northeast Missouri was undertaken to determine whether a division is justified, as proposed by some stratigraphers, of these argillaceous beds into two formations. The formations were sampled systematically at surface exposures on the northeast limb of the Lincoln Arch in the vicinity of Hannibal and Louisiana, Missouri. The samples were investigated mineralogically in the laboratory. Previous studies showed that the fossils of the Grassy Creek and Saverton beds were virtually identical. The present study demonstrates that the Grassy Creek and Saverton beds are too near alike in …

Free Energy And Entropy Of Translation Tables, Paul W. Gilles, Gordon A. Gallup

Gordon Gallup Publications

In the statistical calculation of the thermodynamic properties of ideal gases the translational contribution is calculated from the Sackur-Tetrode equation, S = R1n (2π MkT)^3/2 ÷ (h³ N^5/2) V + 5/2 R in which S is the entropy of one mole of a gas of molecular weight M, at absolute temperature T, and volume V expressed in cubic centimeters; k is Boltzmann's constant; h is Planck's constant; N is Avogadro's number; and R is the molal gas constant expressed in the same units as those desired for S, usually cal deg¹ mole¹.
