Organ Doses In Routine Radiographic Procedures, Yang Han

Theses and Dissertations

There is general agreement that the extent of the risk from x-ray examination is related in some way to the radiation dose. As the dose increases, the likelihood of significant biological effects also increases. If a clear correlation between dose and effect is to be established, a convenient and reasonably accurate method of estimating patient’s absorbed doses during common radiographic examinations will be highly needed. A simple method is developed in this project to determine the two important parameters e exposure at skin entrance (ESE) and half value layer (IIVL), which is essential to get reasonably accurate estimates of absorbed …

Sedimentary Depositional Cyclicity, Mission Canyon And Charles Formations (Mississippian), Williston Basin, North Dakota, Jean L. Hoff

Theses and Dissertations

Workers within the Williston Basin have repeatedly reported the presence of sedimentary cyclicity within the carbonate and evaporite succession of the Mississippian Madison Group. Descriptions of cyclicity are diverse and commonly conflict. Previous work has been exclusively qualitative. This study used a group of statistical techniques in a method designed specifically for the objective identification and evaluation of cyclicity in the lithofacies sequence of the Mission Canyon and lower Charles Formations in North Dakota.

Twelve cores were sampled at every visually distinguishable lithologic unit. Forty-six lithologic components were counted in each sample on a presence-absence basis. The phi association coefficient …

Hydrogeological And Hydrogeochemical Evaluation Of A Proposed Flue Gas Cleanup Dry Waste Disposal Pit Near Beulah, North Dakota, Nathan T. Hunke

Theses and Dissertations

The Coyote I electrical operating station of the Montana Dakota Utilities Company (MDU) is located near Beulah, North Dakota. Flue gas cleanup {FGC) dry waste is generated by the facility in the conversion of coal to electricity. MDU submitted a permit application to the North Dakota State Department of Health {NDSDH) to dispose of FGC dry waste in a strip-mined area 1.6 kilometres northeast of the plant.

Two disposal pits were proposed by MDU, a Phase I and Phase II pit. The objectives of the investigation were to determine the hydrogeological and hydrogeochemical suitability of the site for FGC waste …

Coyote Mail, John R. Salter Iii

Theses and Dissertations

This thesis consists of four short stories. They are traditional in the sense that each involves a conflict, and resolution of a conflict. "Coyote Mail," the first story, deals with a grandfather who must face the fact that change is inevitable, and that he cannot interrupt it. "Ambush" involves a young man who, after being pushed to the limit by a bully, decides to take drastic action. The third story, "Every Blue in the Sky" concerns a law enforcement officer who finds himself forced to think about his racial heritage. The fourth story, "Big Rabbit Sets Me Free," concerns a …

Ethnogeography Of Middle Missouri River Indians: 1738-1889, Kenneth C. Dagel

Theses and Dissertations

The purpose of this thesis is to present the ethno- geography of the Mandan and Hidatsa Indians, and to a lesser extent, the ethnogeography of the Arikara and Lakota during the period 1738-1889. It provides not only a listing of place-names, but it also includes an explanation of why the locations associated with those names were so important, and remain important to these tribes.

The primary hypothesis of this research is that toponyms of Native American origin were generated because of perceptual and/or pragmatic reasons. Place-names, obtained from historical journals and secondary sources, were classified using a standard toponym typology. …

Multiphase Flow In Vertical And Inclined Annuli, Rajeev Patel

Theses and Dissertations

The present study was undertaken to experimentally determine the in situ volume fraction of the gas phase when air is bubbled through a stagnant liquid column. The data gathered were used to examine the model proposed by Hasan (1986) for estimating gas void fraction during two-phase flow in vertical and inclined pipes. This model, based on a drift flux approach, relates the in situ velocity of the gas phase to the bubble rise velocity and the mixture velocity.

An experimental set-up consisting of a plexiglass column of 5 inch inside diameter and eighteen feet in height was used to gather …

A History Of School Reorganization In Sargent Country Since 1947, Larry E. Skroch

Theses and Dissertations

Sargent County's school district reorganization story began in 1947. In that year North Dakota's first comprehensive school district law was passed. Sargent County had twenty-nine school districts but needed a larger tax base to improve the quality of education. By November 1947, a County Reorganization Committee was formed and its actions became front-page news. School reorganization ignited great excitement throughout the county, and public interest ran high in 1948 because people worried about losing their schools and about possible tax increases. As people took sides, some friend ships were broken; town residents became united in the defense of their school, …

Beliefs Of Accounting Faculty/Business Deans At Small Schools Regarding Selected Aacsb Undergraduate Business Administration Accreditation Standards, Leonard J. Sliwoski

Theses and Dissertations

Cost Control And Pricing Methods For The Small Business, Mikel S. Brantley

Theses and Dissertations

An important part of the American dream is the ability to start and own a business. Hundreds of thousands of new firms are started each year. Small business is the heart of the American economic system and essential to its overall well-being. The failure rate of small businesses, however, is a major concern to businessmen and government at all levels. It causes economic losses to both individuals and taxpayers through increased business loan rates and the costs of bankruptcy filings. A lack of management education is often cited as a direct cause for business failures. Chief among management problems is …

The Test Of English As A Foreign Language Sample Test As A Measure Of Adolescent Language Ability, Paul Gardiner Osborn

Theses and Dissertations

Relative performance on the Test of English as a Foreign Language Sample Test (TOEFL-ST) was explored in sixty native English speaking high school students. Subjects also were administered the Fullerton Language Test for Adolescents and the Peabody Picture Vocabulary Test Revised. The TOEFL-ST was not difficult for this population, indicating that TOEFL tests taken by foreign speaking college students probably assess a level of native English competency well below the high school level. The three tests, including subtests, appear to measure a wide array of subdomains of language competency. The data do not support the conclusion that any of these …

Stratigraphy And Depositional History Of The Deadwood Formation (Upper Cambrian And Lower Ordovician), Williston Basin, North Dakota, Douglas B. Anderson

Theses and Dissertations

Based on gamma-ray characteristics, the Deadwood Formation is divided into six informal, attribute-defined units, members A through F. Members A and Bare Late Cambrian in age; members C through Fare Early Ordovician in age. The type section of the Deadwood, in the northern Black Hills, is dominated by Upper Cambrian strata. Much thicker Lower Ordovician rocks occur in the deeper portion of the Williston Basin.

The Deadwood comprises the Sauk sequence and represents the initial Paleozoic transgression or the seas on the North American craton. Eight smaller-scale transgressive-regressive events occurred on the craton during the Late Cambrian and the Early …

Pressure-Solution Features Of The Birdbear Formation (Devonian), Williston Basin, North Dakota, James C. Collier

Theses and Dissertations

Pressure-solution features of the Birdbear Formation (Devonian), Williston Basin, North Dakota were the subject of this study. In the area studied, the Birdbear Formation is primarily a limestone with mud-rich textures. The investigation contained three principal phases: 1) a study of the parameters influencing the size and shape of the pressure-solution response, 2) the process of reactate dolomite formation and its relation to calcite neomorphism, and 3) the relation of neomorphism to pressure solution.

The principal pressure-solution response types are stylolites and solution seams. Stylolites are pressure-solution seams with a tooth-and-socket, serrated shape. Pressure-solution seams are gently undulating to smooth …

Characterization And Utilization Of High- And Low-Sodium Lignite Of The Beulah-Zap Bed (Paleocene), Indian Head Mine, Southwestern North Dakota, Gale G. Mayer

Theses and Dissertations

A study of high- and low-sodium lignite of the Beulah-Zap bed sampled at the Indian Head Mine, Pit 11 and 12, respectively, in Mercer County, North Dakota and fly ash derived from utilization tests on the lignite, indicates the fly-ash composition and related utilization potential can be correlated to coal geochemistry.

Average lithotype abundances for each of the sampling sites were estimated to be vitrain 50%, attritus 45%, and fusain 5%. Attritus occurs more frequently in the upper part and vitrain in the middle and lower parts of the seam. Maceral groups, identified microscopically, were (in order of decreasing abundance): …

The Effect Of Man On The Landscape And The Effect Of Land On The Manscape: Or Contingent Plans For Knowing A Mountain, Taylor Scott Baldwin

Theses and Dissertations

In my artistic practice, I emphasize personal and pan-cultural anxieties regarding civilization and the environment as an impetus for work in sculpture, video, and drawing. By locating marginal microcosmic subject matter that tellingly exhibits macrocosmic global dread, I seek to capture and distill our overwhelming eco-socio-political anxiety into a portrait of a society at a point in its history when the specter of nameless impending disaster weighs pressingly on the collective psyche. This thesis is supplementary to my work of sculpture in the Graduate School of the Arts Thesis Exhibition at the Anderson Gallery opening on April 27th, 2007. The …
