The Effect Of Oil-And-Gas Well Drilling Fluids On Shallow Groundwater In Western North Dakota, Edward C. Murphy

Theses and Dissertations

Upon completion of an oil-and-gas well in North Dakota the drilling fluid is buried in the reserve pit at the site. Reclamation of the drill site is expedited by digging a series of trenches which radiate out from the reserve pit, The majority of buried drilling fluid is ultimately contained within these 5-7 metre deep trenches. These fluids are commonly salt-based, i.e. they contain a con centration of 300,000±20,000 ppm NaCl. In addition, these drilling fluids also contain additives including toxic trace-metal compounds.

Four reclaimed oil~and-gas well sites were chosen for study in western North Dakota. The ages of these …

The Effect Of Waste Stabilization Pond Seepage On Groundwater Quality Of Shallow Aquifers In Eastern North Dakota, David J. Brown

Theses and Dissertations

The use of stabilization ponds to dispose of municipal wastes has become popular with many North Dakota cities. When managed properly they are an efficient and economical method of waste disposal and may not adversely affect groundwater quality. In order to achieve efficient treatment, the ponds must be built in sediment that has permeability low enough to inhibit excessive percolation of wastewater into the subsurface. Some North Dakota cities have not met this basic requirement in the construction of their ponds. As a result, insufficiently treated pond liquids are allowed to reach the water table, potentially contaminating groundwater supplies. Three …

Lignite Liquefaction Using Carbon Monoxide And Water In A Hot-Charge Batch Autoclave, Michael L. Swanson

Theses and Dissertations

The effects of temperature history on the liquefaction of lignite were investigated using the UND hot-charge, time-sampled batch autoclave facility. Approximately two hundred grams of moisture- and ash-free lig nite, one hundred grams of water, four hundred grams of hydrogenated anthracene oil solvent and carbon monoxide gas were reacted in both cold- charge and hot-charge experiments. The oil yields and overall conver sions were determined by extraction with cyclohexane and tetrahydrofuran, respectively. Maximum operating pressures ranged from 3670 psig to 3925 psig and the maximum reaction temperature was approximately 420°C in all cases.

Oil yields and overall conversion ranged from …

Autoclave Studies Of Lignite Liquefaction, Bruce G. Miller

Theses and Dissertations

The effect of time at reaction temperature on the liquefaction of lignite using hydrogen or synthesis gas was studied. A slurry contain ing 200 grams of moisture-ash-free (MAF) lignite, 100 grams of water, and 400 grams of hydrogenated anthracene oil solvent was fed into the University of North Dakota Time-Sampling Hot-Charge Batch Autoclave System with the gas at an initial pressure of 400 psig.

Oil yields and conversions ranged from 0.9 percent to 35.7 percent and 66.7 percent to 90.6 percent, respectively, increasing as the time at or near the reaction temperature (380-420°C) increased. Higher con versions and greater oil …

Changing Land Use In The Rural-Urban Fringe: A Case Study Of Southwest Grand Forks, Jane M. Wilson

Theses and Dissertations

Between 1954 and 1980 significant changes took place in southwest Grand Forks. The predominant land use in 1954 was cultivated cropland, which covered 80.5 percent of the total study area. By 1980 cropland had declined to 26.7 percent of the total, with urban land uses such as single family residential, strip development and shopping center making significant increases. As the area became urbanized, problems devel oped. In 1979 the English Coulee unexpectedly flooded, damaging homes and the acute care hospital in the study area. In 1981 developers owed $2.4 million in delinquent special assessments.

In order to describe the land …

Consensus Information In The Newspaper Advice Columns, Danel E. Rubanowitz

Theses and Dissertations

The present study investigated the naturalistic use of consis tency, distinctiveness and consensus information, which are the three information variables in Kelley's (1967) covariation model of attribu tion. Newspaper advice columns were used as a naturalistic source of social data.

The first question addressed in this study was whether or not Kelley's (1967) three information variables are ecologically valid. If perceivers in the "real world" actually use covariation information to support or defend their attributions, then it should be possible to reliably locate these pieces of information. If the information is used, it would be possible to examine whether perceivers …

Design Optimization Of Slider-Crank Mechanisms Subject To Coulomb Bearing Friction, Anthony J. Pascuzzi

Theses and Dissertations

Optimization techniques are applied to the design of slider-crank mechanisms operating as single acting compressors subject to Coulomb bear ing friction. The dynamic force analysis is performed by the solution of a set of nonlinear equations in dimensionless form. The optimization re sults presented are for various cases of inertia, friction, and external loading.

The optimization procedure developed minimizes a weighted sum of the input work and bearing shear stress by adjusting the mechanism's dimensions. The independent dimensions that are varied are the connecting rod length, the offset, and the three bearing radii. The results of the optimization are different …

Bromine Chloride Treatment Of Aqueous Gasifier Effluent, Theodore T. Poppke

Theses and Dissertations

The feasibility of treating slagging gasifier wastewater with bromine chloride was studied. The aqueous effluent was collected from the spray washer of the Grand Forks Energy Technology Center's slagging fixed-bed gasifier during run RA-94.

It was found that slagging gasifier wastewater is only partially treatable using bromine chloride as the principal treatment step. After a pretreatment scheme consisting of lime addition and ammonia stripping, bromine chloride was unable to reduce the total carbon concentration of the wastewater to acceptable discharge or reuse levels.

Bromine chloride addition as an aqueous solution, a liquid, and a vapor was investigated. Bromine chloride vapor …

Microreactor Studies Of Lignite Liquefaction, Gary B. Hanson

Theses and Dissertations

An investigation of the effects of staged heating on the liquefaction of lignite was conducted using 20 ml. microreactors heated in a fluidized sandbath. One gram of moisture-ash-free lignite, two grams of hydrogenated anthracene oil solvent and synthesis gas (carbon monoxide and hydrogen) at an initial pressure of 1200 psi were used in all runs. The net conversion and oil yields were studied as a function of time and temperature at each stage. The total reaction time was varied from 10 to 30 minutes and the reaction temperature from 350° to 460°C.

Oil yields and conversions ranged from -2.8 percent …

Four Utah Mormon Artists As Authors, Roxie Dale Trimble

Theses and Dissertations

In researching the literary and visual art forms of four Utah Mormon artists/authors, considerable evidence supports the prognosis that natural parallels do exist between the written and visual works of artists/authors. Recent as well as past historical data also confirms this hypothesis.

To implement research personal interviews and written questionnaires were submitted. The resultant data compiled supports the prognosis that this parallelism does exist.

Person-Environment Interaction In Nursing Homes For The Elderly, Stan J. Orchowsky

Theses and Dissertations

There has been a growing interest in recent years in the study of person-environment interaction in the elderly. Several theoretical models have been proposed in the gerontological literature. Each of these models suffers from one or more limitations, including the restriction of requiring that the person and the environment be measured in the same terms, and the difficulty posed by attempting to empirically test the model.

A new model of person-environment interaction in the elderly is proposed here. The model views life satisfaction as the ultimate outcome variable. Feelings of personal control and choice are seen as intervening between life …

The Communicational Function Of Wearing Apparel For Lady Missionaries Of The Church Of Jesus Christ Of Latter-Day Saints, Alice W. Buehner

Theses and Dissertations

Because the need exists for a professional image among lady missionaries, this thesis will define what knowledge concerning communication of clothing is necessary in order to create a desirable image of professionalism. The term "professional" is derived from available research describing the most appropriate attire for women business executives. In lieu of an experimental study by this author, the interpretation of the professional look is supported by Molloy's extensive research on women's wearing apparel. His research shows that beyond a doubt, the skirted suit and blouse give women "a look of authority and a sense of presence in business." In …

The Relationship Of Frequency And Social Desirability Of First Names With Academic And Sex Role Variables., Debra Ruth Crisp

Theses and Dissertations

Much research has been done to support the notion that name stereotypes exist. These stereotypes appear to be related to the popularity of names. The present study was conducted in an effort to discover whether certain types of names were actually associated with different behavioral or attitudinal factors in the people who possessed those names.For a sample of 1094 University of North Dakota students who were first-time entering freshmen in the fall of 1977, the following data was collected, as much as possible, for every subject: first name; the number of times the name occurred in the population; a social …

Articulation Practices In Nabte Member Institutions Regarding Shorthand And Typewriting Courses Completed In High Schools And Noncollegiate Post-Secondary Schools., Mary Hill Turner

Theses and Dissertations

The problem of this study was to identify the articulation practices in effect in NABTE (National Association of Business Teacher Education) member colleges and universities regarding students who had completed shorthand and/or typewriting courses in high schools and noncollegiate post-secondary schools before entering the teacher education program.A total of 296 questionnaires were mailed and a total of 224 usable returns were included in this study.Significant differences were found in articulation practices based on financial support, regional accreditation and AACSB/NCATE membership.While there was little evidence of the existence of statewide articulation programs, public institutions were less likely to be involved. Public …
