The Effect Of Spontaneous Crystallization Of Some Inorganic Compounds At The Critical Temperature Of Their Solvents, John William Buttrey

Masters Theses

"For many years the phenomena which occur at the critical temperature of liquids have been investigated. And since 1912, when Laue and other discovered that a beam of x-rays could be made to yield a diffraction pattern by passing it through a crystal, scientists have been attempting to change the x-ray pattern for various crystals by somehow changing the arrangement of the atoms in the crystal lattice. Harvalik has already shown that crystallization occurs when a solvent reaches the critical point and his work indicates that under these conditions of crystallization there is a change in the crystal pattern. The …

The Post-Kansan Geologic History Of The Lower Platte Valley Area, Gilbert Carl Lueninghoener

University Studies (University of Nebraska) (1888–1984)

This investigation is essentially a geomorphological study of the lower Platte River Valley area in eastern Nebraska. The area comprises Saunders, Dodge, Washington, Douglas, Sarpy, and Cass counties. The area defined above is one of the most critically located of any for the study of the post-Kansan history of the lower Platte River Valley. It lies between the older till (Nebraskan and Kansan) borders to the west and the younger till (Illinoian, Iowan, and Wisconsin) borders to the east. Physiographic changes have therefore transpired in a strictly post-Kansan periglacial region. The Kansan till is the youngest in the area. The …

Alkylaminoalkyl Esters Of 2-Thiophene Carboxylic And Furoic Acids, Henry Alouis Rutter Jr.

Master's Theses

The association of local anesthetic activity with alkaninoalkyl ester of aromatic carbonyl acids has been well susbstantietes. Compounds obtained as varieties of the "anesthesiophoric" group are usually capable of some degree of local anesthetic activity.

Arithmetical Vocabulary : A Factor In Verbal Problem Solving In Sixth Grade Arithmetic, Ernest A. Hoopes

Master's Theses or Doctor of Nursing Practice

During the writer's experience of teaching in elementary and junior high schools in Kansas he had excellent opportunity through supervision and classroom teaching to note a more-than-ordinary difficulty experienced by most children in the subject of arithmetic. Not only was the dull student baffled by the subject but many times the average and good students were "lost" when certain problems were presented. The exceptional. troublesomeness of this subject led the writer to ponder on the possible cause or causes of incorrect problem solving. One thing was apparent from observation and this was that many children seemed to lack a readiness …

Alkylaminoalkyl Aryoxyacetates, William Kenneth Easley

Master's Theses

Numerous inInvestigations into the preparation, properties, and effects plant growth substances have been carried out. It has been shown that phenoxyacetic acids, napthoxyacetic acids, esters, anides and salts of phenoxyacetic acids and certain substituted products of these acids are plant growth promoting substances.

It is the purpose ot this work to produce esters of phenoxyacetic and napthoxyacetic acids which contain a secondary amino group and as a result of their ability to form acid salts, such as hydrochlorides, water soluble compounds. These compounds would be readily applicable to plants in sprays.

A Device For Determining The Electrical Characteristics Of Common Industrial Electronic Tubes, Addison Dabney Campbell

Master's Theses

Many tube checkers designed for radio receiving tubes have been developed . Most of the devices for test­ ing these tubes do little more than check the emission of the cathode. This is usually accomplished by applying alternating voltage to the plate of the tube undergoing the test and reading the direct-current component of the plate current . In this case, the control grid bias volt­ age is usually set at a fixed value although sometimes facilities for varying the bias are provided. If the tube is of the multi-grid type, all the grids except the control grid are connected …

Geology And Mines Of The Upper Blackfoot Valley, Montana, Thomas K. Shea

Bachelors Theses and Reports, 1928 - 1970

The purchase and continued operation of the Mike Horse mine in the Heddleston district, by the American Smelting and Re­fining Company, gives the Blackfoot Valley a renewed promise of a prosperous future in its role as a mining district. In the past, large amounts of placer gold were recovered from the gulches of the area, however, because of the transporta­tion facilities, only the upper portions of a few lodes were exploited by the early miners.

Rugose Corals Of The Madison Group, William R. Paine

Bachelors Theses and Reports, 1928 - 1970

One of the best types of index fossils, and one which occurs most plentifully in the Madison group of formations in Montana, and yet, one which has been little studied, is the group of rugose, or cup, corals. Perhaps this group of fossils has not been studied in detail because their distinguishing characteristics are mainly internal, and labo­ratory preparation in the form of thin section or polished surfaces is necessary to bring out these characteristics.

Kibbey Sandstone In Montana, Glen Shean

Bachelors Theses and Reports, 1928 - 1970

Much attention has recently been given, by geolog­ists, to prolific water bearing horizon and a potent­ial oil horizon, known as the Kibbey sandstone, which lies deeply buried under much of central Montana. In some local­ities the sandstone is dry, and its identification in cut­tings from deep wells has in many cases proved difficult.

Two sets of weld-test coupons, supposedly made under identical conditions, were submitted to this institution last year for approval and certification under the A.S.M.E. Welder's Qualification Code. The first set of coupons was unsatisfactory. The second set, made by the same operators one month later, was satisfactory.

Corrosion Testing Of Iron-Tin Alloys By The Salt Spray Method, Bernard T. Mcdonald

Bachelors Theses and Reports, 1928 - 1970

The purpose of this study was to determine the rela­tive rate of corrosion of iron-tin alloys containing low percentages of tin. Since in the world today, a great deal of work is being done to develop large tin deposits and new methods devised to treat these ores, it is possible that the metal will become abundant and will obtain a more important position in the metal industry.

The Corrosion Resistance Of Iron-Tin Compacts As Produced By Powder Metallurgy, Robert W. Gambill

Bachelors Theses and Reports, 1928 - 1970

The art of Powder Metallurgy deals with the preparation of metal powders and their utilization. As a more pertinent definition, the following has been suggest­ed: "Powder Metallurgy is the art of producing metal powders and shaped objects from individual, mixed, or alloyed metal powders, with or without the inclusion of non-metallic consti­tuents".

Geology And Mineral Deposits Of Idaho: A Summary, Paul B. Bronken

Bachelors Theses and Reports, 1928 - 1970

The great diversity on mineral wealth in Idaho establishes it as one of the principle mining states in the union. Mining first began in the state with the discovery of placer gold in the Pierce City district in 1861, and since that date has become one of the leading industries of the state.

Upper Cretaceous Sediment In Montana, Frank J. Frankovich

Bachelors Theses and Reports, 1928 - 1970

Cretaceous sediments in Montana record events during a period of unusual geologic interest. After a long period of extensive submergence of the area during Jurassic time, came a period of varying continental and marine deposition with consequent variations in the types of sediments laid down. A study of these variations, their extent, and their cause has been the primary object of this thesis.
