Coupled Downflow Biological Fluidized Bed Process, Chong Seng Ong

Theses and Dissertations

Bench-scale treatability research conducted at the University of North Dakota Sanitary Engineering Laboratory demonstrated that the coupled, downflow, biological fluidized bed process was an effective system for the treatment of synthetic fuels processing wastewater. In the biological fluidized bed process the nitrification and denitrification columns were coupled to nitrify ammonia to nitrite and/or nitrate, and then to denitrify nitrite and/or nitrate to nitrogen gas, in addition to the breakdown of carbonaceous and organic nitrogen. The wastewater used in the research was generated by the Great Plains Coal Gasification Plant located at Beulah, North Dakota. The two fluidized bed reactors contained …

Study Of Char Particle Combustion Using Thermogravimetric Analysis, Mihir Manookumar Patel

Theses and Dissertations

Combustion of North Dakota Beulah lignite char (82.5 microns) has been studied on a DuPont 951 Thermogravimetric analyser. Three oxygen partial pressures of 5, 10 and 20 % in nitrogen, and seven different temperatures from 598 K to 923 K were utilized in isothermal combustion experiments. Slow pyrolysis at 1023 K for 5 minutes greatly reduced the reactivity of the original char. Temperature had a definite effect on reaction rate and the higher the temperature, the greater the rate. Two distinct reaction zones were observed. At lower temperatures, chemical control dominated with an activation energy of 28 to 34 kcal/gmole, …

Estimational Abilities And Mathematics Achievement Of Seventh Graders, Mary Elizabeth Mendenhall

Theses and Dissertations

Computational estimation and mental computation are two of the most neglected areas of today's mathematical curriculum. Much has been written about these two concepts, but little instruction has been carried out in the classroom (Johnson, 1979; Reys, 1986). Freeman (cited in Reys & Bestgen, 1981) states that less than 3% of textbooks had estimation lessons. Reys (1987) found that only 4% of lessons in all fourth-grade textbooks of the early 1980's deal with estimation. Also, Buchanan (1978, p. 2) observes that: "Instruction in. estimation is not something that has been tried and failed; it has not been tried on any …

The Relationship Between The Strategies Of Adolescents On Microcomputers In Problem-Solving Sessions And Problem-Solving Times, Linda Meeks

Theses and Dissertations

The purpose of this study was to investigate the relationship between strategies used by students in problem solving and the amount of time necessary for the problem solution.

A portion of the curriculum for 7th grade Life Science, teaching problem solving, was converted into three computer problem-solving tasks to be done by 76 seventh graders who worked in pairs to solve the problems. Each pair of students timed themselves as they worked toward a solution while the computer recorded the number of clues used in order to reach a solution. The Pearson product-moment correlation was used to obtain a coefficient …

Seventh-Grade Student Achievement In Length, Perimeter, Area And Volume, Cathy Pierce

Theses and Dissertations

This study was designed to measure seventh-grade achievement in finding length, perimeter, area and volume when four different presentations of the problem were given: standard textbook problems, word problems, students measuring, and problems labeled differently than the standard textbook problems. Each of the 235 subjects took one of four different measurement skills testes developed by the researcher. Results indicate student achievement decreases as the complexity of the attribute increases. Overall, students found standard textbook problems the easiest to solve, followed by word problems, and students measuring, respectively. Problems labeled differently than the standard textbook problem were the most difficult for …

Assessment Of Influence That The Church Of Jesus Christ Of Latter-Day Saints Has On Exercise Habit Of Members Living In Utah County, Gary L. Preston

Theses and Dissertations

This study identified and analyzed the influence the Church of Jesus Christ of Latter-day Saints had on the decision of 309 respondents to exercise. The data obtained from the questionaires were analyzed using chi-square to compare males and females. Within the limitations of this study, the following conclusions were justified: women were more influenced by the LDS Church to exercise than men; LDS males and females exercised more than average American adults; walking, jogging, and aerobic dance were the most popular choices of LDS exercisers; and, there is a need to improve the awareness of LDS members concerning the Physical …

John Nock Hinton: The Reconstructed Life Of An English Born Mormon Convert Of Virgin City, Utah, Lenora Atkin Meeks

Theses and Dissertations

John Nock Hinton, an Englishman, was converted to the Church of Jesus Christ of Latter-day Saints in Birmingham, Warwickshire, England in 1856. The motivating factor in his life, thereafter, was his strong conviction that the Church was the literal kingdom of God on the earth, and its leaders were God's prophets, and its mission was to usher in the last dispensation on the earth, the Millennium, and the second coming of the Savior. His duty, as he saw it, was to labor unceasingly to help accomplish that mission, to work out his own salvation, and to teach his children the …

False Positive Rates Encountered In The Detection Of Changes In Periodontal Attachment Level, John C. Gunsolley

Theses and Dissertations

This thesis demonstrates that the assumption of normality used by Goodson results in the underestimation of the type I error rate of the tolerance method by a factor of 10. This underestimation is due to the positive kurtosis demonstrated in the distribution of replicate differences. Therefore, the assumption of normality does not seem warranted. It is shown here that a resampling technique more accurately estimates the type I error rate.

The estimates of false positive rates have important implications in the field of periodontics. When diagnostic decisions are based on single measurements, false positive rates are high. Even when thresholds …

Evaluation Of The Interaction Between Seepage From A Municipal Waste Stabilization Lagoon, Mcville, North Dakota, And A Shallow Unconfined Aquifer, Paul R. Bulger

Theses and Dissertations

The McVille, North Dakota, Municipal Waste Stabilization Lagoon is situated above the McVille Aquifer, an unconfined glaciofluvial aquifer capable of significant water yields. The site contains a 3-D network of 29 monitoring wells. Standing waste-water is maintained in the clay-lined, primary-operating cell. Operating practices at the site entail periodic discharges of waste-water from the lined cell to an unlined cell, a procedure which results in rapid infiltration.

The shape and extent of the groundwater contaminant plume caused by the waste-stabilization process is best delineated by the distribution of chloride. Background wells contain less than 10 mg/L chloride. The area up …

Depositional Environments And Diagenesis, Winnipegosis Formation (Middle Devonian), Williston Basin, North Dakota, Nancy A. Perrin

Theses and Dissertations

In the Williston Basin, the Winnipegosis Formation is the major carbonate unit of the initial transgressive-regressive pulse of the Kaskaskia sequence. Twenty-two lithofacies were identified by well-log, core, and thin-section studies of Winnipegosis rocks; these belong to seven environments of deposition which include deep basin, deep shelf, shallow shelf, reef, lagoon, tidal flat, and evaporite basin. The deposition of the Winnipegosis and Prairie Formations were inter-related and occurred during six episodes. Following a brief hiatus separating the underlying Ashern Formation from the Winnipegosis, a clear, quiet, shallow-marine environment became established in the North Dakota portion of the Elk Point Basin. …

Depositional Environments Of A Portion Of The Bullion Creek Formation (Paleocene), Western Billings County, North Dakota, Rodney K. Perkins

Theses and Dissertations

The Bullion Creek Formation (Paleocene) in North Dakota is part of an Upper Cretaceous to Eocene wedge of siliciclastic rocks formed during uplift associated with the Laramide Orogeny. The Bullion Creek Formation consists predominantly of mudrocks , with fine-grained sandstone, lignite, and rare limestone lenses . Previous workers have postulated combinations of fluvial and lacustrine depositional environments for the rocks.

The study area covers 15 square kilometres in the badlands of the Little Missouri River in western Billings County, North Dakota, where approximately the upper 75 metres of the Bullion Creek Formation ls exposed. Twenty nine stratigraphic sections were measured …

Geohydrologic Evaluation Of A Proposed Coal-Ash Disposal Site Near Mandan, North Dakota, David M. Ronnei

Theses and Dissertations

Montana-Dakota Utilities Company (MDU) operates Heskett Station, a 100 megawatt coal-fired power plant, located near Mandan, North Dakota. In the process of generating electricity, MDU's Heskett Station produces approximately 62,000 tons of coal-ash annually. The ash has been disposed of by above-ground stockpiling on the plant site for the past 35 years. Limited storage space and new solid waste regulatory restrictions have necessitated the search for a new ash disposal site.

This investigation focused on selecting a disposal site that would be suitable for long-term disposal of coal-ash generated at Heskett Station. Specifically, the objective was to locate a site …

A Mineralogical Study Of The Harmon Lignite Bed, Bullion Creek Formation (Paleocene), Bowman County, North Dakota, Christopher J. Zygarlicke

Theses and Dissertations

Study of the Harmon lignite bed at the Gascoyne Mine in Bowman County, North Dakota showed that most of the minerals in the coal lithobodies were detrital in origin and that variable ash deposition during combustion may be caused by variations in types and quantities of mineral phases.

The Harmon bed is part of the Bullion Creek Formation (Paleocene). Objectives of this study included: to develop scanning electron microscope/microprobe techniques for the study of minerals in coal; to determine the origins of the mineral phases; to postulate a depositional environment for the Harmon lignite; and to ascertain whether variable ash …

Metamorphism In The Wabigoon Subprovince In The Vicinity Of Vermilion Bay And Sioux Lookout, Ontario, Christine K. Roob

Theses and Dissertations

The Wabigoon-English River subprovince boundary has been proposed by various workers to be either a fault, an unconformity, an intrusive contact or a gradational boundary. North of the Wabigoon Fault, in the Vermilion Bay-Dryden area, migmatization and partial melting of meta sediments have produced a variety of metatexitic and diatexitic migmatites. Because migmatites are not encountered in the Wabigoon subprovince proper and the area north of the Wabigoon fault is so different from the rest of the subprovince, it is thought that the area may constitute the southernmost part of the English River sub province.

The Wabigoon Subprovince is a …

A demographic data sheet was prepared by the researcher from which general data were gathered for the study.Data were analyzed by analyses of variance, multiple comparisons of means, and a simple t-test. No significant results were found among the different majors (elementary, secondary, elementary/early childhood, elementary/special education) and their scores …

A Rorschach Study Of Lateralized Differences In Emotion., Gregory James Tharp

Theses and Dissertations

Several studies in the field of laterality have suggested that the left and right cerebral hemispheres of the brain may play different roles in emotional as well as cognitive processing. A study was conducted to test several specific hypotheses derived from theories proposing that the right hemisphere (RH) may have a generally greater involvement in emotional behavior, may be more expansive and less constrained by rational or conventional thinking, and may be particularly involved in such negative emotions as sadness.Twenty-five male and twenty-five female adult volunteers were each presented five Rorschach slides to the left visual hemifield (LVF) and five …
