An Ecologic Study Of An Overloaded Oxidation Lagoon Containing High Populations Of Purple Sulfur Bacteria, Harvey W. Holm Jan 1969

An Ecologic Study Of An Overloaded Oxidation Lagoon Containing High Populations Of Purple Sulfur Bacteria, Harvey W. Holm

Theses and Dissertations

Concomitant with the addition of large amounts of potato starch wastes to the Grafton, North Dakota, municipal sewage lagoon was the development of a new major microbial population, the purple sulfur bacteria. This study attempts to define ecologic relationships of the lagoon, with special emphasis placed on the action of purple sulfur bacteria in the lagoon.

Chemical changes in the lagoon were investigated by monitoring Biochemical Oxygen Demand (BOD), sulfide, sulfate, phosphate, pyruvate, total carbohydrates, volatile acids, alkalinity, and pH. Lagoon water temperatures were observed daily. Microbial ecologic relationships were deduced by enumerating coliforms, fecal conforms, enterococci, total bacteria (TGE …

A Study Of Earth Science Teachers And Practices In North Dakota For The Academic Year 1968-1969, Howard C. Reith Jan 1969

A Study Of Earth Science Teachers And Practices In North Dakota For The Academic Year 1968-1969, Howard C. Reith

Theses and Dissertations

In the period between 1961-1964 the North Dakota department of Public Instruction initiated long overdue changes in the science curriculum for the seventh, eighth, and ninth grades of the public schools. Titese involved changes from general science to the life, earth, and physical sciences. During this same period there was a re vitalization of interest in earth science at the national level, with the public school enrollment rising from several thousand to well over one million.

Because of the rapid national growth in earth science enrollment, and the status of earth science in North Dakota, a study to determine the …


A Comparison Of The Late Wisconsinan Molluscan Fauna Of The Missouri Coteau District (North Dakota) With A Modern Alaskan Analogue, Samuel J. Tuthill Jan 1969

A Comparison Of The Late Wisconsinan Molluscan Fauna Of The Missouri Coteau District (North Dakota) With A Modern Alaskan Analogue, Samuel J. Tuthill

Theses and Dissertations

Study of forty fossiliferous sites in late Wisconsinan sediments from the Missouri Coteau district in central North Dakota has defined the molluscan fauna of the period of geologic time between 12,000 and 9,000 C14 years before the present. The fauna includes twenty-eight taxa of nonmarine gastropods and bivalves and is dominated by branchiates. The modern molluscan fauna of the Missouri Coteau district in North Dakota lacks four species which were resident in the late Wisconsinan and contains no unionids, one additional aquatic species, and is strongly dominated by pulmonate gastropods.

The geology of the Missouri Coteau has been interpreted as …


Personality Types And Their Hypothesized Attributes: An Application Of Holland's Vocational Choice Theory, Ronald W. Kristjanson Jan 1969

Personality Types And Their Hypothesized Attributes: An Application Of Holland's Vocational Choice Theory, Ronald W. Kristjanson

Theses and Dissertations

The purpose of this study was to assess the usefulness of Holland's vocational choice theory for counseling with university students. More specifically, it attempted to determine whether or not Holland's theory provides a suitable framework for integrating the results of two commonly used counseling instruments: the SVIB and the EPPS .

A sample was drawn from those students tested by the University Counseling Center on both the SVIB and EPPS. This sample was, within reasonable limits, representative of the male student population dealt with by the Counseling Center. The sample contained 255 Ss.

For analysis of the data the student …
