Alkylation Of Phenol, Raymond Joseph Thimineur

Honors Theses

The purpose of this research project is to study the alkylation of phenol with n-butyl alcohol and optically active l-sec-butyl alcohol using a chemically activated alumina catalyst. The reaction of n-butyl alcohol with phenol is studied to determine if the alcohol is rearranged to give the same products obtained by alkylating with sec-butyl alcohol. The object of reacting optically active l-sec-butyl alcohol with phenol is to determine if the optical activity is retained, decreased, or complete racimazation occurs with this catalyst.

Thermal And Arc Resistance Of Polyester Resin Glass Reinforced Laminates, Frederick B. Budnik

Honors Theses

The heat resistance of several types of polyester resins are studied by measuring the flexural strength of glass reinforced laminates before and after conditioning at 200°C. Arc resistance readings are also taken. The type of saturated acid, glycol and monomer is varied. The ratio of saturated to unsaturated acid and the ratio of monomer to base resin is also studied. Chlorendic acid improves the heat resistance over phthalic and isophthalic acids but it lowers the arc resistance. Ethylene glycol yields resins with the highest flexural strengths. Styrene monomer content has little effect on heat resistance up to 40%. In the …

Thermodynamic Properties Of Water Adsorbed On Kaolinite, S. John Bennett

Theses and Dissertations

The object of the work presented in this thesis was to obtain quantitative values of the thermodynamic changes in water upon adsorption by kaolinite. Two methode were used. The first was a determination of the differential heat content and entropy of adsorption. The second method included a thermodynamic evaluation of the B.E.T. "c" constant expressed in terms of the Gibbs standard free energy of adsorption. The experimental data gave satisfactory results in determining the differential and standard thermodynamic functions or free energy, entropy, and heat content of adsorption. The adsorption of water on kaolinite appears to be a van der …

Certain Equivalence Relations In Transformation Semigroups, Carol G. Doss

Masters Theses

The general object of this thesis is to study certain equivalence relations defined on a semigroup, in particular, to study certain equivalence relations defined on semigroups of single-valued transformations. We are interested in semigroups of transformations partly because every semigroup has as homomorphic image a semigroup of transformations (and hence a subsemigroup of a transformation semigroup of degree n for some n). This is a well-known fact, analogous to the Cayley Theorem on abstract groups, but we shall give a brief proof in Section 1. Section 1 is devoted to definitions and basic concepts. In Section 2 we prove some …

The Decomposition Of Solid Barium Nitrate By Gamma Rays, Lawrence E. Lamar

Chemistry and Chemical Biology ETDs

Very little work has been done on the chemical effects produced during the irradiation of solid materials. Although some research has been reported concerning the action of ultraviolet light on solid nitrates, most of the information in the literature is based upon the use of nuclear radiations.

Two types of reaction mechanisms have been proposed by previous authors. The direct decomposition of the metal nitrate to give the nitrate and oxygen was concluded from measurements of optical absorption. The ionization of nitrate ion to yield mononitrogen trioxide which could disassociate after capture of an electron was also suggested. The mononitrogen …

The Mathematical Theory Of Meteorite Penetration Into Earth-Targets, Richard D. George

Physics & Astronomy ETDs

A problem in mathematical ballistics of fundamental importance in meteoritics is investigated in this thesis, namely the problem of estimating the speed at which a meteorite of assigned shape, mass and density struck a specific earth-target, either from purely theoretical considerations or from penetration or other impact-effects actually observed and measured in the earth-target.

In the second chapter several methods for calculating impact-velocities based on terminal ballistic theory are developed. While some of these methods can be successfully applied to as many as 63 recovered meteorites, others are applicable only to a very few known meteorites because of the failure …

Hydrologic Data Collection Program For New Mexico, Ralph L. Strother

Civil Engineering ETDs

The objective of this thesis is to present a program for the collection of basic hydrologic data for the state of New Mexico. It is an expansion of the existing program which currently becomes more inadequate with the progressively extensive use of the water resources of the state. The need for hydrologic data for planning and operation of water use and control structures far exceeds that obtained by the existing program.

Types of data reported upon are climatological, stream flow, ground water, quality of water, suspended sediment, snow cover and reservoir, valley and channel sedimentation. For the purposes presented herein …

A Survey Of The Effects Of Changes In PH, Solvent And Salt Concentration Upon The Rate Of The Periodate-Glycol Reaction, Jay E. Taylor, Benadetto Soldano, George A. Hall

Chemistry Department: Faculty Publications

A quantitative study of the effect of the periodate- glycol complex upon the rate of the periodate-glycol reaction was made in an earlier paper. The data for the present paper were taken before those of the previously published paper and, for the most part, before the importance of the periodate-glycol complex had been recognized. It has not been possible therefore to interpret the present data with the degree of thoroughness of the earlier paper. However, certain very interesting conclusions can be made.
The Effect of Variation of pH.
Effect of Changes in Solvent.
The Effects of Certain Salts.

The Salt Lake Group In Cache Valley, Utah And Idaho, Robert D. Adamson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Fluvial and lacustrine sediments of great thickness accumulated in the intermountain basins of the western United States during Tertiary time. The Salt Lake group in northern Utah and parts of surrounding states is a conspicuous stratigraphic unit of these basins. The "beds of light color" in Morgan Valley in the Wasatch Mountains of northern Utah were named the "Salt Lake group" by Hayden (1869) because of similar occurrences in Salt Lake Valley and because he reasoned that the succession could be divided into formations. Similar rocks crop out in Ogden Valley, north of Morgan Valley, and in Cache Valley, Utah …

A Management Study Of The Cache Elk Herd, Norman V. Hancock

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

American elk, by virtue of their distribution, were the most cosmopolitan members of the cervid family at the time of white settlement of North America. At this early date elk were present in every major region of what is now continental United States, as well as in northern Mexico. they likewise were abundant in upper and lower Canada, though records do Lot corroborate their presence too far north on the Atlantic coast. Although generally existent throughout the western states, elk were sparsely distributed in Nevada, southern Utah, and most of Arizona and New Mexico. Paucity of elk was also noted …

Preparation, Purification And Cis-Trans Isomerization Of 2-Butene-1, 4-Diol, Roman Stephan Slysh

Honors Theses

The preparation of cis- and trans-2-butene-1,4-diol has been reported in chemical literature by numerous workers. A well established procedure to obtain the cis isomer is to hydrogenate 2-butyne-1,4-diol at two to four atmospheres pressure in the presence of catalysts, such as Raney nickel or colloidal palladium. This reduction is selective and can be stopped easily at the ethylenic stage. The reaction has been studied by Lozac'h who stated that the Raman spectrum of 2-butene-1,4-diol prepared in this way indicates the presence of the cis iomer only. Lozac'h does not mention the degree of purity of this product and nothing could …

Geology Of A Portion Of The Hand Mine, Argenta Mining District, Beaverhead County, Montana, John Thomas Richards

Bachelors Theses and Reports, 1928 - 1970

The Hand Mine is located in the Argenta Mining District near the town of Argenta. The area surrounding the Hand Mine is characterized by intense thrusting, folding, and igneous activity. The area mapped by the author is in the southeast portion of the mine and differs from the rest of the mine in that no commercial ore has been found. The writer concludes that the steep faulting and flatlying bodies are of two different ages, and that intense oxidation has altered the ore minerals to plumbojarosite.

Oxidized Copper Mineralization Along The Continental Fault Near Butte, Montana, Theodore H. Eyde

Bachelors Theses and Reports, 1928 - 1970

Located in the fault zone of the Continental fault near the western edge of Boulder batholith of southwestern Montana the oxidized copper deposits are developed by three open pit mines, one of which is a presently in operation. Copper has been deposited by descending cold solutions which have leached copper from the surrounding quartz monzonite and deposited within the crushed fault zone. Local high grade 'bunches' of ore occur along narrow limonite veins, remnants of primary sulfide veins which have been enriched by the descending cold solutions.

The Influence Of Soil Moisture Conditions On The Absorption Of Phosphorus By Plants From Calcareous Soils, T. J. Denman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Phosphorus is one of the major plant nutrients secured from the soil. The object of many investigations has been to discover the nature of the processes by which the soil supplies phosphorus to plants, and to determine the influence of soil factors upon these processes. Although much knowledge has been gained, these processes and the effects of soil factors upon them are still not clearly defined.

One factor which profoundly affects plant growth is the amount and relative availability of soil moisture. The results of some investigations have suggested that this factor may also have considerable influence on the absorption …

Two Unusual Occurrences Of Microstylolites, Benjamin H. Burma, Charles M. Riley

Department of Earth and Atmospheric Sciences: Faculty Publications

Microstylolites are here reported in both quartzite and in welded tuff. Descriptions of these unusual occurrences and accompanying photomicrographs suggest difficulties in applying the widely held theory of pressure-solution for the origin of these features.

Paleosols Of The Oligocene Of Nebraska, C. Bertrand Schultz, Lloyd G. Tanner, Cyril Harvey

Bulletin of the University of Nebraska State Museum

Prominent paleosol ("buried" or "fossil" soil) complexes occur at the top of the middle Orella, upper Orella, lower Whitney, and upper Whitney in the Brule formation of Nebraska; and at the top of the "Lower Oreodon," "Middle Oreodon," "Upper Oreodon," and "Leptauchenia" beds in the Brule deposits of South Dakota. These paleosols have regional distribution and appear to be of value in stratigraphic correlations. Major faunal breaks seem to coincide with important buried soil zones, thus indicating that certain paleosols actually represent unconformities. Some of the soils were developed on old land surfaces where deposition was practically at a standstill …

Industrial Wastes, Charles E. Renn

United States Environmental Protection Agency: Publications

This paper presents a summary of experiences with a variety of cyanogenic wastes. The work has attempted to evaluate the interaction of waste bearing waters and the environment in terms of waste disposal design requirements. In this, the approach is somewhat more critical than that commonly taken by fisheries biologists, conservationists, and others who have been concerned with the "preventive" aspects of waste disposal.

The first phases of the work were designed to discover the tolerable limits of certain waste components to fresh water fish. This was undertaken in 1950; in the interval the composition of the wastes has been …
