The Worm Creek Quartzite Member Of The St. Charles Formation, Utah-Idaho, Anthon V. Haynie Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This report presents the results of a stratigraphic study of the Worm Creek quartzite, the basal member of the St. Charles formation of Upper Cambrian age. The member is present in the Bear River Range, the Malad Range, and the Promontory Range of Northern Utah and southeastern Idaho. The Worm Creek quartzite was differentiated as the basal unit of the St. Charles formation by Richardson (1913) and named for its occurrence in Worm Creek Canyon in the Bear River Range, Bear Lake County, Idaho.

A stratigraphic investigation of the Worm Creek quartzite, including thickness and lithologic changes, was made. Through …

Geology Of The East-Central Part Of The Malad Range, Idaho, Prapath Prammani

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

During recent years geologic investigations have been made in various parts of northern Utah and southern Idaho. In the Cache Valley area. the Bear River Range which bounds the east side of the valley has been studied and mapped. On the west side of the valley, the Wellsville Mountain and the southern part of Malad Range have also been studied. Still, little is known about the east-central part of the Malad Range. The study of this area will give additional information to the over-all picture of the geology of the region. The purpose of this thesis is threefold. The first …

The Use Of Branchiostegal Rays To Determine Age Of Lake Trout Salvelinus Namaycush Walbaum, Ross Vivian Bulkley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Any method used in aging fish must fulfill certain requirements to be satisfactory. If the method is inaccurate, naturally little reliance can be placed upon its use. If considerable study of the method and much practice are required before accurate readings can be obtained, the method will not come into widespread use. The requirements of an aging method, then are that it must be accurate and comparatively easy. The scale method for aging lake trout (Salvelinus namaycush Walbaum) unfortunately does not fulfill these requirements. It has always been difficult to tell the age of lake trout by the examination …

Relationship Of Bicarbonate Concentration Of Plant Tissue To That Of The Growth Media As A Factor In Chlorosis, Gary H. Carlsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Throughout the years lime-induced chlorosis has contributed to untold economic losses. Although this disease has challenged the technical ingenuity of outstanding plant and soil scientists, the exact cause has never been determined; consequently, no preventative measures or permanent cures can, as yet, be recommended. This physiological malady, unchecked, continues its rampage in regions where the disease is prevalent.

The problem is of wide significance because calcareous soils are distributed throughout the world. It is of primary concern to us because the majority of the land of western United States is of this type. An estimated 500,000 acres of crops growing …

The Dehydrocyclization Of Normal Heptane To Toluene With Supported Rhenium, Platinum And Molybdenum Catalysts, Robert R. Beishline

Theses and Dissertations

The dehydrocyclization activity of supported platinum, molybdenum and rhenium catalysts was studied by determining the toluene yield from n-heptane as a function of temperature and metal concentration in the catalyst. The support was 100 to 200 mesh alumina. Metal concentrations of 0.01% to 1.0% platinum, 0.1% to 2.0% molybdenum and 0.1% to 2.5% rhenium were studied in the temperature range from 500° to 600° C. Platinum was shown to be superior to both molybdenum and rhenium at all temperatures and metal concentrations investigated. The rhenium data were somewhat erratic, but showed rhenium to be a poor dehydrocyclization catalyst. The apparatus, …

Biological Indices Of Water Pollution, With Special Reference To Fish Populations, Peter Doudoroff, Charles E. Warren

Other Publications in Wildlife Management

A number of investigators have very recently published discussions having to do with biological indices and biological measures of water pollution (1) (2) (7) (13) (14) (15) (16) (26) (27) (28) (29) (30) (36) (38). Fjerdingstad (12) has discussed some of the pertinent European literature. The fundamental concepts presented by these authors are not original, for the idea that aquatic organisms can be useful "indicators" of environmental conditions, and particularly of the degree of pollution of water with organic wastes, has a long history (12). Because of certain novel features and the relatively wide scope of the studies, and the …

Velocity And Friction Characteristics Of Laminar Viscous Boundry-Layer And Channel Flow Over Surfaces With Ejection Or Suction, E. R. G. Eckert, Patrick L. Donoughe, Betty Jo Moore

Armstead Publications and Presentations

National Advisory Committee for Aeronautics Technical Note 4102

Information collected from the referenced literature and supplemented by new solutions is presented on the flow characteristics - velocity field, pressure drop, and friction - for steady, fully developed laminar flow through a duct consisting of two parallel walls, for flow through tubes with circular cross section, and for boundary-layer flow over infinite wedges. It is assumed that the fluid either is ejected through the porous walls into the main flow or is removed from the main flow by suction. The properties of the fluid both in the main flow and in …

The Urea Adducts Of The Constituents Of California Montan Wax, Alan Howard Vanderbilt

University of the Pacific Theses and Dissertations

Interest in the chemical constitution of montan wax began with the work of Von Boyen, who in 1901 showed montanic acid to be a constituent of the wax. In the years that followed the literature has been rich with respect to investigations of montan wax. Most of the literature concerns itself with the technology of the wax, its uses, methods of refining and purification. Much has also been written on its chemical make-up.

It was the purpose of this research to explore the possibility of forming urea adducts of the normal components of montan wax, and to investigate the properties …

A 120 Megacycle Self-Contained High-Frequency Titrimeter, John Kyle Clinkscales Jr.

University of the Pacific Theses and Dissertations

The analytical chemist is ever eager to improve and expedite present analytical methods.. In the past ten years considerable interest .has been elicited in the field of high frequency oscillators and their application to analytical chemistry. One of the main reasons for this interest is the uniqueness of the apparatus. No direct contact is made between the measuring instrument and the solution. Credit tor this interest must be given primarily to Jensen and Parrack of Texas A & M University. Their article in 1946 described a simple tuned plate-tuned grid electronic oscillator, operating in the high frequency range. A solution …

Medial Pleistocene Fossil Vertebrate Localities In Nebraska, C. Bertrand Schultz, Lloyd G. Tanner

Bulletin of the University of Nebraska State Museum (1924–2023)

The accurate geologic dating of Pleistocene vertebrate localities which occur outside the glaciated regions has always been difficult. Several new fossil localities in Nebraska now provide data for a better understanding of the paleoecology and faunal evidence of the medial Pleistocene of the Great Plains region.

A fossil quarry, containing the remains of both vertebrates and invertebrates, has been discovered in south-central Nebraska (11/2 miles south and west of Angus in Nuckolls County). The fossils are preserved in Sappa silts in a lime concentration zone (C horizon) of a Yarmouth paleosol. The calcium carbonate appears to have been responsible for …

Nebraska Deer, William Bailey Jr., George Schildman, Phillip Agee, C. G. Pritchard

Nebraska Game and Parks Commission: Publications

IN COMMON with the experience of most states, Nebraska's deer herds were reduced to a very low level by excessive harvests in our early history. Most American big-game animals were overharvested in the early history of this nation because of commercialization. Buffalo were killed for their hides, deer for their meat. This slaughter continued as long as the hunter (or poacher) could sell his take at a profit. Modem game management and public opinion reversed this trend. Deer are on the way back all over America, and in some states the protection-complex was so strong that deer were restored to …

Influence Of Various Factors On Aggregation Of Peorian Loess By Microorganisms, T. M. Mccalla, Francis A. Haskins, E. F. Frolik

Department of Agronomy and Horticulture: Faculty Publications

Soil structure is important in the attainment of adequate aeration for the aerobic microorganisms whose activities maintain such higher plant nutrients as sulfur, phosphorus, and nitrogen in a highly oxidized and thus readily available state. Good soil structure is also necessary for soil and water conservation, Under Nebraska conditions microorganisms and their decomposition products constitute a major source of soil-aggregating agents. The decomposition of crop residues and plant roots is important in the nutrition of these aggregating microorganisms. Other microorganisms, however, also utilize crop residues and plant roots, and they may decompose the aggregating agents as well, so that the …

Transference Numbers Of Concentrated Manganous Chloride Solutions, Marshall L. Severson

Masters Theses

"Electrolytic conduction differs from metallic conduction only in the nature of the carrier of the current. In the case of metallic conduction the carrier is electrons. The passage of an electric current through an electrolyte occurs only by the movement of ions of opposite charge moving in opposite directions under an applied potential. The current carried by a particular ionic species is a direct function of the concentration, the charge on the ion, and the ionic mobility. A transference number is the fraction of the total current a given ion carries in a particular electrolyte undergoing electrolysis. The sum of …

Detection Of Low Energy Positive Ions By Scintillation Methods, Graydon J. Hanson

Masters Theses

"This thesis deals with the feasibility of efficiently detecting low energy positive ions, those with energies of less than several hundred electron volts, using phosphors.

The scintillation technique, first used visually and greatly improved in the last ten years by the use of a photomultiplier tube, has greatly advanced detection in high energy fields. The photomultiplier is capable of delivering milliampere pulses of current of short duration and these can be registered directly by the many electronic devices currently in use.

Extensive work has been done with phosphors which scintillate under which energy bombardment, due in part to their wide …

A Geological Study Of The Irvine Ranch Area, Johnson And Campbell Counties, Wyoming, Gale E. Butterfield

Masters Theses

"The discovery of uranium in the Powder River Basin, Wyoming, by the U. S. Geological Survey in 1952 has lead to an extensive exploration program throughout the region by both private and governmental agencies. This report is a geological study of an area in the southwestern part of the basin.

Geological and radiometric mapping carried out as a part of this report indicated several areas of uranium occurrence. Some of these occurrences warrant tests by drilling.

Mineralogical and petrographic study has shown the principal uranium minerals to be carnotite and metatyuyamunite. The mineralization occurs in arkosic sandstones. Assays of the …

The Value Of Including Chemistry Content In The Study Of High School Biology, Ramon Duane Buckley

Dissertations and Theses @ UNI

The purpose was to evaluate the effect of including some definite chemistry content in high school biology. This evaluation was made by comparing outcomes of instruction in two different groups of a high school biology course. The two groups were equated in terms of the intelligence quotients, the sex, and the previous achievement in biology of the class members. The comparative gains in factual knowledge were measured by means of an evaluation test. The comparative gains in appreciations and interests in biology were measured with a questionnaire.

A Study In Predicting Success In Algebra, Leslie Milton Graham

Dissertations and Theses @ UNI

Students of Manson High School at Manson, Iowa, select either algebra or general mathematics, subject to the approval of the principal. Some of the students' achievement records are incomplete, thus handicapping the principal in guiding the students to make their choices. As a result, several students have chosen to try algebra and have failed, and sometimes they have become discouraged and have left high school. It occurred to the writer that, if a predicting device could be established to show the student his chances in mathematics, it possibly could spare the pupil's failing in algebra.

Preparation Of Thiochalcone From Thioacetophenone, Thomas Joseph Reilly

University of the Pacific Theses and Dissertations

This thesis covers the practical research done on the condensation of thioacetophenone with benzaldehyde and the library research covers the chemistry of thioketones and the thioflavanones. Most of the thioketones have been made by dissolving a ketone in ethanol, usually absolute although 95 percent was also used, saturating the solution with anhydrous hydrogen chloride at ice temperature, then admitting hydrogen sulfide for several hours. This method was first used by Fromm and Baumann when they made thioacetophenone from acetophenone. David Shirley also gives theis process in his book “Preparation of Organic Intermediates” published by Wiley and Sons in New York. …

The Synthesis Of 7-Methyl-3,4-Benzpyrene, 6,7-Dimethyl-3,4-Benzpyrene, 10-Methyl-3,4-Benzpyrene And 7,10-Dimethyl-3,4-Benzpyrene, Joseph Leonard Comp Jr.

Chemistry and Chemical Biology ETDs

Interest in carcinogenic compounds began to develop when a form of cancer was found occurring in chimney sweeps in 1775. Skin cancer was found among workers in tar industries in 1875, and in 1887 workers in cotton spinning industries were known to have cancer which was attributed to contact with lubricating oils. Girls who painted the luminous dials of watches contracted cancer from exposure to the radioactive paint, and men who worked with B-naphthylamine developed bladder cancer. Many other cases of occupational cancer were reported before a systematic study of carcinogenic substances was begun. Early attempts to produce cancer in …

Range Liverstock Nutrition And Its Importance In The Intermountain Region, C. Wayne Cook

Faculty Honor Lectures

It has been estimated that about 728 million acres or about 76 percent of the entire land area in the West is used for grazing (Stoddard and Smith 1956). In Utah about 93 percent of the land area or 48,900,000 acres is considered range land (Reuss and Blanch 1951). Although some of this range land is forested, a large area of it can be used only for grazing. Therefore, range livestock production is an important segment of western agriculture.

Before 19'00 most of the animals in the West grazed on the range all year. However, irrigation crop production has expanded …
