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

Master's Theses

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.

Solubility Determinations In Anhydrous Ethylenediamine, Joseph Hooker Dusenbury

Honors Theses

Although the preparation of ethylenediamine is reported in the literature as early as 1853, the first isolation of the pure anhydrous compound was performed by A. W. Hoffmann in 1858. He prepared the pure diamine by repeated distillations from metallic sodium, and reported on the great stability of the 111ono-hydrate as a hindrance to obtaining the compound in a pure state, More recently, in 1934, Bailar at the University of Illinois reacted the crude diamine with zinc oxalate to give a salt which is stable at room temperature and may be heated to 200° in vacuo (all temperatures in degrees …

The Preparation Of Phenyldibromnitromethane, Edwin L. Mincher

Honors Theses

The purpose of this research was to prepare plenyldibromnitromethane. Also it was desired to make some physical measurements on the compound if the compound could be made in sufficient quantity. So far as the author can find out, phenyldibromnitromethane is not described in the literature.

A Study Of The Action Of Potassium Hypobromite And Sodium Hypochlorite On Adipamide, William Marzluff

Honors Theses

The Hoffman reaction of an amide with a hypohalite to give a primary amine in excellent yields is the basis of many syntheses in organic chemistry. This project is concerned with the study of the action of sodium hypobromite and sodium hypochloride on adipamide. Isolation of reaction products, if possible, identification of reaction products, if possible, identification of the products, and determination of the yield of the reaction were desired. It was hope that a diamine, putresecine, would result from this reaction, and therefore the steps in isolation of the products were carried out with this in view.

A Partial Study Of The Reaction Between Pentanedione-2,4 And Formaldehyde, Joseph Anthony Sincius

Honors Theses

It was the purpose of this research to observe the reaction of pentanedione-2,4 with formaldehyde, and to study the principle reaction product. The secondary purpose of the research was, if possible, to obtain a cyclic compound like 1,3 dihydrorescrcinol.

Dialysis Of Silicic Acid Gels, Arthur C. Glamm

Honors Theses

The primary purpose of this investigation was to prove or disprove the existence of an equilibrium between polysilicic acid molecules and simple silicic acid molecules in a set silicic acid gel. The investigation involved the controlled dialysis of typical gels from their time mixing, through the time of set and into the aging period. Since numerous silica determinations were to be made, it was thought advisable to disregard the time consuming gravimetric method. The secondary purpose of this investigation was therefore, to determine if the colorimetric method for the determination of silica, as devised by Winkler (1) in 1914 and …

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.

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.

An Investigation Of A Particular Weldment Failure, Byron Clow

Bachelors Theses and Reports, 1928 - 1970

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.

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.

Occurrence Of Native Copper Near Jefferson City, Montana, Terence G. Kirkland

Bachelors Theses and Reports, 1928 - 1970

Sometime prior to 1870, a group of prospectors made what was believed to be a "rich strike' on one of the tributaries of Prickly Pear Creek in Jefferson County, Montana. Instead of striking it rich, they had uncovered a native copper deposit, worthless to them because of its limited extent and remote location, but now of much interest to the geologist, and to the mining engineer because of its possible commercial value.

Electro-Deposition Of Iron From A Chloride Bath, Charles W. Noon

Bachelors Theses and Reports, 1928 - 1970

Iron was electro-deposited from a ferrous chloride bath. Studies were made of deposits formed when current density was varied, and fin­ally when both current density and temperature were changed. An attempt was made to lay the ground work for a long range study of the chloride bath, and to determine the most simple conditions possible for obtaining a smooth, even, and thick deposit.

General Geology And Mines Of Northwestern Montana, Robert L. Sandvig

Bachelors Theses and Reports, 1928 - 1970

The five counties discussed in this paper compose the northernmost and westernmost counties in Montana. On the eastern boundary are Glacier National Park and the Continental Divide; on the southern boundary are Missoula and Powell counties; Idaho lies on the southwestern and western side; and the Canadian border lies along the northern edge. The region is on the Pacific Ocean side of the Rocky Mountains. Three major rivers, the Clark Fork, the Flathead, and the Kootenai drain this area into the Columbia River.

The Problem Of The Tensleep Sandstone, George D. Mccarthy

Bachelors Theses and Reports, 1928 - 1970

Sandstone is probably one of the most important groups of rocks in existence today. The economic importance of so insignifi­cant a thing as a mass of sand grains grows with the true reality of the situation. By increasing our knowledge of grains of sand, or particles of sandstone in all their ram­ifications, it would undoubtedly reflect upon our everyday life by increasing commercial possibilities of an undevel­oped natural resource of Montana.

Isopach Maps And Discussion Of The Ordovician And Devonian Of Montana And Adjacent Areas, Arden F. Blair

Bachelors Theses and Reports, 1928 - 1970

The intensive postwar search for new petroleum horizons has resulted in widespread prospecting in the northern Great Plains. No commercial production has as yet been derived from Ordovician or Devonian rocks in Montana, but the relat­ively few tests that have penetrated to critical depths have disclosed encouraging conditions which merit further consider­ation, especially in Devonian strata.

The Anodic Polishing Of Copper In Solutions Of Orthophosphoric Acid, Robert E. Sullivan

Bachelors Theses and Reports, 1928 - 1970

The electrolytic cleaning of metals by anodic methods has been known for many years. It was recognized long ago that when the temperature and concentration of the electro­lyte were properly regulated, bright clean surfaces were obtained.
