Elasticity And Plastic Flow Of Silicic Acid Gels, Clarence Kenneth Lasher

Honors Theses

Rubber is a very common example of a substance which has both elastic and plastic properties. If a rubber band is placed over two pegs, it is stretched and behaves elastically. There will be a certain tension in the rubber band but as time goes on, this tension lessens. The rubber has undergone a certain amount of plastic flow. It has been the purpose of this research to study the analogous situation in the case of silicic acid gels.

Heats Of Solution Of Halogen Methanes In Liquid Ammonia, Robert W. Davison

Honors Theses

Introductory experiments were carried out to see just which halogen methane derivatives, if any, produce heat changes when dissolved in liquid ammonia. There are indications given in the chemical literature to expect that certain of the halogen methanes should dissolve in liquid ammonia with the evolution or absorption of heat. This present research work involved investigation of such compounds as chloroform, carbon tetrachloride, bromoform, and also iodoform. Only introductory heat measurements were made. More work must be done to confirm and enlarge upon results presented here.

Physical And Chemical Properties Of Soil Profiles Of The Scott, Fillmore, Butler, Crete, And Hastings Series, Henry W. Smith, H. F. Rhoades

Phosphate Deposits In Western Summit, Wasatch, Salt Lake, Morgan, And Weber Counties, Utah, Alvin M. Hanson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Phosphate deposits in the western United States have been the subject of considerable discussion in the last decade, and during the last few years much interest has been aroused in them. Phosphate was first discovered in this area in 1889, but it was not until 1906 that the United States Government took active interest in the study of these deposits. The investigation by the government of the occurrence of western phosphate was begun by Weeks and Ferrier (10), and later carried on by others. On December 9, 1908 the western phosphate reserve was created and many acres of land were …

Parabos Dodsoni Barbour And Schultz: A Correction, Erwin Hinckley Barbour, C. Bertrand Schultz

Department of Earth and Atmospheric Sciences: Faculty Publications

A Bos-like animal, Parabos dodsoni, was recently described by Barbour and Schultz (1941, "A New Fossil Bovid from Nebraska", Bull. Univ. Nebr. State Museum, Vol. II, No. 7, pp. 63-66, Figs. 24-27, December) as a new genus and species from the Pleistocene of Nebraska. Attention has been called to the writers by Dr. E. H. Colbert of the American Museum of Natural History that the name Parabos is preoccupied. Parabos was introduced as a generic name by C. Arambourg and J. Piveteau (1929, "Note preliminaire sur un Ruminant du Pliocene inferieur du Roussillon," C. R. Bull. Soc. Geol. de …

A Chromium Plating Bath Containing Sodium Benzenesulfonate Instead Of Sulfuric Acid, Edward Burleigh

Bachelors’ Theses

At the present day chromium plated articles are saving the country many tons of badly needed metals. The beautiful, bright,luster that chromium has is no longer the prime quality that makes its use so extensive. Today its extreme hardness has taken the foremost place. Parts worn by use and re-claimed with chromium, not only wear longer than the original ones· but they also save valuable metal and time put into new ones. New articles plated with chromium have increased life, and thus the time and metal needed for replacement is greatly reduced.

The present chromium plating baths containing sulfuric acid …

The Cleaning Action Of Detergents And Soaps On Printer's Ink And Lubricating Oils, Daniel David Holzman

Bachelors’ Theses

During the past few years, industry has developed a steadily increasing interest in certain new types of synthetic organic compounds.

Industry devoted to the cleaning of textiles has found the removal of printer's ink and lubricating oils a tedious operation.

There has been developed and perfected a series of synthetic materials which successfully meet modern needs.

The detergents, in general, have some or all of the following properties: wetting-out, dispersing, emulsifying, penetrating, and cleaning.

There seems to be a need to investigate some of these new detergents for commercial cleaning purposes.

An Experimental Investigation Of The Age Hardening Of Nickel With Boron, Willard M. Boam

Bachelors Theses and Reports, 1928 - 1970

Since 1911, at which time, the age hardening phenomenon of duralumin was discovered by Film, much re­search has been carried on investigating the various alloy systems. The successful application of age hardening to the copper aluminum system (duralumin) has indicated the possibility of hardening practically all the metals in the same way.

The Velocity Of Falling Particles In A Liquid Medium, Elliott Coldwater

Bachelors Theses and Reports, 1928 - 1970

The investigation was prompted by the fact that there seemed to be some discrepancy between the results published by Richards,and the empirical figures used in classification and in gravity concentration. Further, the work of Richards was restricted to quartz and galena whereas this study also includes pyrite and calcite.

The Recovery Of Zinc From Butte Mine Waters, Edmond M. Fern

Bachelors Theses and Reports, 1928 - 1970

Very little work has been done towards the recovery of zinc from mine water because the zinc content of the water is generally low. As different from copper, which can very easily be replaced by iron in any of its solutions, zinc is very high up in the electro-chemical series and so the few metals above zinc, most of which are rare and hence expensive, cannot be used to replace zinc from its solution.

Polishing Mineral Specimens By The Use Of An Optical Polishing Machine, Wilbur J. Guay

Bachelors Theses and Reports, 1928 - 1970

The problem in this investigation was to determine if mineral specimens mounted in bakelite, or lucite, could be polished for microscopic examination by the use of an optical polishing machine, and if this method would cut down the length of time required to polish specimens by the methods now in use.

Mineralogy And Genesis Of The Vermiculite Deposits At Libby, Montana, Raymond Kujawa

Bachelors Theses and Reports, 1928 - 1970

The problem considered in this report is one of the mineralogy and mode of formation of the extremely pure, large bodies of vermiculite. Mineralogically the ultrabasic intrusive, with which the economic mineral is associated, presents an array of rather unusual minerals. The determination of these minerals, their associations, and the sequence of alteration that lead to the formation of the vermiculite bodies, constitutes the problem.

Sizing By Elutriation Of Finely Ground Quartz And Pyrite, Elmer C. Polson

Insoluble Residues Of The Lower Mississippian Limestones Of The Madison Group, Fred G. Lines

Bachelors Theses and Reports, 1928 - 1970

The correlation of non-fossiliferous drill samples is one of the difficult problems that is en­countered in sub-surface stratigraphy. In order to truly correlate a formation, it must have some dis tinctive features and have an areal persistence of these features. These requirements are probably met best by limestone.
