The Effect Of Waste Stabilization Pond Seepage On Groundwater Quality Of Shallow Aquifers In Eastern North Dakota, David J. Brown Jan 1983

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 …


The Effect Of Oil-And-Gas Well Drilling Fluids On Shallow Groundwater In Western North Dakota, Edward C. Murphy Jan 1983

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 …

Glacial Stratigraphy Of Northwestern Cass County, North Dakota, Sharon K. Falcone Jan 1983

Glacial Stratigraphy Of Northwestern Cass County, North Dakota, Sharon K. Falcone

Theses and Dissertations

Field mapping, construction of cross-sections, and laboratory analyses of field samples were used to map, describe, and correlate the Late Wisconsinan glacial sediments of northwestern Cass County, North Dakota and to interpret the glacial history of the area.

The surficial geology of the area was interpreted as: 1) collapsed glacial sediment, 2) glacial sediment draped over pre-existing glaciolacustrine topography, 3) proglacia1 lake sediment, 4) wave-eroded glacial and lake sediments and 5) recent river sediment. Landforms within each of these areas include eskers, abandoned or overfit river channels, transverse ridges, ice thrust masses, kettles and beach deposits.

Seven lithostratigraphic units were …

Low Molecular Weight Ligands And Trace Element Transport: A Study Employing Modified Gel Chromatography (Milk, Infant Formulas, Zinc)., Mark Thomas Martin Jan 1983

Low Molecular Weight Ligands And Trace Element Transport: A Study Employing Modified Gel Chromatography (Milk, Infant Formulas, Zinc)., Mark Thomas Martin

Theses and Dissertations

The purpose of this study was to detect and identify low molecular weight (<10,000 Da) copper and zinc binding ligands in biological materials believed to function in trace element transport using modified gel chromatography (MGC) as the major detective method. MCG involves the gel filtration of a biological specimen on a column equilibrated with a chosen metal ion. In this way, the ligands can be separated from each other without being separated from the investigative metal ion. The ligands were separated by molecular weight on the gel matrix and the column eluent was monitored for metal binding peaks by the use of atomic absorption spectrophotometry. Several ligands could be detected in a single sample and the detection limit was 0.1 (mu)mol for some common ligands.Milks and infant formulas were examined for the human species-specific zinc binding ligand thought to be essential to the acrodermatitis enteropathica (AE) infant. Citrate was detected in all milks but picolinate was not detectable in any. Formula, human, and goat milk also contained detectable free amino acids. Human and bovine milk proteins also bound metal. No human species-specific ligands were detected. Alternative causes of the diet-dependent AE zinc deficiency and a mechanism for the molecular origin of AE are suggested.Viokase, a porcine pancreatic extract, has been found to be effective in the treatment of variant AE, an effect reportedly due to the presence of citrate or picolinate. Neither ligand was detectable by MGC although amino acid ligands were highly concentrated. Given the competitive nature of trace metal-ligand binding, some other aspect of Viokase probably ameliorates the variant AE symptoms.Ligands were detected in porcine intestinal mucosa. However, their potential as transport ligands depends on future studies to determine if the ligands were artefacts of sample preparation.Conjugated bilirubin, peptides, and amino acids were identified as ligands in human bile and are probably also present in porcine bile. The peptides were not individually identified but possibly play specific roles in normal copper excretion.


Individual Differences In Information Processing Style As Related To Rorschach W/D Ratio., Lisa Sharon Squire Jan 1983

Individual Differences In Information Processing Style As Related To Rorschach W/D Ratio., Lisa Sharon Squire

Theses and Dissertations

The present study was undertaken to determine whether an over-emphasis on whole vs. large detail locations on the Rorschach Inkblot Test, as assessed by the W/D ratio, would be manifested in individual differences in information processing style. It was hypothesized that subjects with W/D ratios weighted in the whole direction would perform better on visual information processing tasks which require global analysis of the stimulus configuration and which ostensibly are mediated to a greater degree by the right hemisphere. Conversely, it was hypothesized that subjects with W/D ratios weighted in the large detail direction would perform better on information processing …


The Audience In Charleston's Theatres, 1790 - 1860, Pamela Morris Adams Jan 1983

The Audience In Charleston's Theatres, 1790 - 1860, Pamela Morris Adams

Theses and Dissertations

From the perspective of the 20th century, Charleston, South Carolina, seems an unlikely beginning for American theatre, but Charleston of previous centuries had the location and economy to attract theatrical activity. More importantly, Charleston had a population that was consistently receptive to theatre. Eola Willis' The Charleston Stage in the XVIII Century, with Social Settings of the Time demonstrates that a number of American theatrical firsts occurred in Charleston, such as the first performance by a professional actor, the first opera, and the first American prologues.
