The Paleozoic Stratigraphy Of Lorain County, Ohio, Edwin Hugo Wenberg

Honors Papers

During the course of the school year 1936-37 spent at Oberlin, which is situated near the center of Lorain County, Ohio, the writer had the opportunity to study the outcrops and to gather records of wells in this area.

A study of the strata of this county is confusing because the same rocks have been described under different formational names. Originally many of these strata were traced northward from type sections in central Ohio or westward from type sections near Cleveland. At a later date many of the strata were reclassified and assigned to formations which had been traced westward …

Determination Of Fossil Woods (Basswood In Ellensburg Formation), George F. Beck

All Faculty Scholarship for the College of the Sciences

From time to time isolated, rounded pebbles of petrified wood have been encountered in the Ellensburg gravels that overlie the Columbia Basalts in Central Washington. Recently a sufficient number of these specimens were collected to justify a study of the petrified woods of this above-named formation.

The Catalytic Vapor-Phase Hydrolysis Of Benzene And Toluene, Clemens Raebel Maise

Masters Theses

"The vapor-phase synthesis of organic compounds represents a new field of study which has attracted the attention of investigators only within recent years. However, wide interest is apparent in this field and several processes of commercial importance have already been developed. Hydrolysis is perhaps the newest of all the types of vapor-phase synthesis; the literature consists of little more than a few patents...The vapor-phase hydrolysis of benzene and toluene, therefore, presented an interesting possibility. These two hydrocarbons are considered very stable toward water in the liquid-phase. The purpose of this investigation was to determine to what extent their stability toward …

Oil And Gas Resources, Jackson County, Missouri, Joseph Robinson Clair

Masters Theses

"The oil and gas production in Jackson County, though rather small, is nevertheless of considerable economic importance. A portion of the county has been rather thoroughly developed but the remainder has had little prospecting. In order to aid further development in the region the Missouri Geological Survey engaged in the mapping of all the known wells in the county as a basis for preparing a structural contour map of the area. In addition, a member of the Survey staff is stationed permanently in Kansas City to give assistance to the operators in the region and to collect the logs of …

Geology And Ground-Water Resources Of South-Central Nebraska. With Special Reference To The Platte River Valley Between Chapman And Gothenburg, Alvin Leonard Lugn, L. K. Wenzel

Department of Earth and Atmospheric Sciences: Faculty Publications

The investigation here reported, which covered a period of about 5 years, 1929 to 1933, was made for the purpose of determining the available supply of ground water in south-central Nebraska, the origin and discharge of the ground water, and the relation of the geologic and ground-water conditions in the Platte River Valley to the conditions occurring under the plains to the south. The area was found to be underlain by permeable Pleistocene and Tertiary sand .and gravel, much of which is saturated and yields relatively large quantities of water to wells. Except in a few isolated places the ground-water …

A Brief Consideration Of The Different Methods Of Integration, Donald Golden

Master's Theses or Doctor of Nursing Practice

Any student of mathematics is familiar with the importance of the process of integration. Integration is as fundamental to analysis as the basic principles of the number theory are to arithmetical calculation. Some of the common applications of integration are, finding the distance a falling body has travelled during a particular interval of time; to determine the equation of a curve, given different conditions (such as slope of the curve equal numerically to one-half the abscissa, or some similar problem); motion of a projectile; motion in a resisting medium; finding areas and volumes of revolution; length of a curve; areas …

Determining Fossil Woods (Western Conifers), George F. Beck

All Faculty Scholarship for the College of the Sciences

In this paper we come to consider the problem of the coniferous woods. One cannot always recognize with certainty that a given wood is a conifer, yet in ninety percent of the specimens recognition is simple.

The Preparation Of Glucuronic Acid From Gum Acacia, Mary Laurissa Felix

Bachelors’ Theses

Initial interest in the preparation of glucuronic acid from gum acacia was prompted by several reasons. Being interested in both the chemical and biological fields, the subject of glucuronic acid made a strong appeal. Although glucuronic acid was discovered over fifty years ago, its position in physiology remained until recently undefined. Now, however, it seems fairly certain that this compound is closely related to carbohydrate metabolism and plays an im­portant role as a detoxicating agent in the body.

The laboratory preparation of glucuronic acid is still one of the important problems of chemistry. Our present knowledge of its synthesis and …

Remarkable West American Fossil, The Blue Lake Rhino, George F. Beck

All Faculty Scholarship for the College of the Sciences

Bidding for acceptance as fact, and for its place in the sun of fame and notoriety, we come now to the newly discovered fossil rhino animal mold of Blue Lake in Grand Coulee, central Washington. Not that fossil rhinos are rare or that their abundance in the Tertiary of America has waited until the present for revelation, is this fossil important. The feature in the Blue Lake rhino which taxes our credulity is the existence of the thing in what unquestionably must pass as once liquid basaltic lava. That anything organic could pass through the terrific heat and pressure of …

Syntheses In The Thiophene Series, Alfred William Weitkamp

Department of Chemistry: Dissertations, Theses, and Student Research

Summary

The Friedel-Crafts reaction has been used in the preparation of thiophene ketones, some of which were hitherto unknown. Certain limitations of the reaction have been noted.

The mercuration of thiophene ketones has been systematically investigated for the first time. Many new halogen derivatives of benzothienone have been synthesized. These were employed in the elucidation of the structure of a complex mercurial· derived from this ketone.

A new modification of an old reaction has been developed whereby benzothienone can be mercurated quickly and almost quantitatively. Interesting derivatives of this little known ketone have been synthesized. Chief among these are the …

Public Water Supplies Of New Mexico, Kenneth F. Priest

Chemistry and Chemical Biology ETDs

Distribution of population in State. The estimated population for the State of New Mexico for the year 1930 was 423,300. A close observation of the population centers shows them to be scattered over a wide range of territory. The largest city, Albuquerque, has approximately 26,000 citizens. The next sites, according to the 1930 count, are three in number, Santa Fe, Roswell, and Clovis. The remaining population including rural districts do not number over eight thousand people.

A Chemical And Biological Study Of The Waters Of Elephant Butte Reservoir As Related To Fish Culture, John Greenbank

Chemistry and Chemical Biology ETDs

The investigation of fresh-water lakes with respect to fish and other aquatic life had its beginning in Europe in the latter half of the nineteenth century. Probably the only man who may be considered to be the founder of the science of limnology was F. A. Forel, of the University of Lausanne Switzerland. Professor Forel’s work was the start of a rapidly developing branch of study, not only in Europe, but also presently in North America.

Unicursal Bicircular Quartic Studied By Inversion, William A. Uporsky

Bachelors’ Theses

The quartic equation was studied by Arab scholars after their attention to the results of their study of a cubic had not proved very significant. Abu'l-Faradsh completed the Fihrist (c, 987), and in this he refers to a problem by Abu’l-Wefa (c, 980). The Arabs were Interested in the quartic equation only as they were in the cubic, i.e., from the standpoint of the intersection of two conics.

The group of woods considered in this paper are only superficially alike—no implication that they are closely related is intended. The beginner will almost certainly confuse the compound rays of these various woods with their annual rings.

Radioactive Properties Of The Subterranean Waters Of Ellis County, Kansas., Verne Lippert

Master's Theses or Doctor of Nursing Practice

Soon after the discovery of Becquerel rays in 1896, tests were made on ordinary matter to see if all matter were radioactive. Although there is evidence to show that all matter is radioactive, to a degree and under certain conditions, it has been found that the greater part of the observable effect is due to traces of radioactive material permeating all matter in general. Thus, radium and its products being the most active of radioactive substances, the surface of the earth is covered with traces of these radioactive substances but the amount varies from place to place. Moreover, determinations of …

The Control Of The Grain Size Of Tin., Robert D. Macdonald

Bachelors Theses and Reports, 1928 - 1970

The tin alloys of tellurium are extremely hard and have very great tensile strength. It was thought that the reduction of the rate of grain growth of tin with the addition of tellurium accompanied this hardening and strengthening and such way found to be true.

The Electroplating Of Cadmium From Sulfate Solutions, Lewis S. Prater

Bachelors Theses and Reports, 1928 - 1970

It has been proven that cadmium forms a very satisfactory plate on steel, which has to withstand severe corrosion, especially the corrosion of sea water and spray. The metal is now successfully plated electrolytically from cyanide solutions, but wherever work is carried on with cyanide, there is great danger of poisoning to the workers.
