Primary Production And Nutrient Limitation In Two Prairie Lakes, Roger A. Steinberg
Electronic Theses and Dissertations
Two eutrophic northern prairie lakes, Lake Cochrane and Lake Hendricks, were sampled regularly for chemical characteristics, temperature, transparency, phytoplankton and zooplankton populations. Primary production was determined by the "light" and "dark" bottle technique. Values for the 1971 summer study period ranged from a low of 59.l7 mg C fixed/m2/hr. to a high of 296,67 with a mean of 151.67 for Lake Cochrane. Values for Lake Hendricks ranged from 25.00 to 194.17 with a mean of 110.83. The possibilities of nutrient limitation were investigated through nutrient enrichment experiments in the field. Production was generally not enhanced and was sometimes inhibited by …
Detection And Assay Of Viruses Using Latex Particles, Thomas Charles Sorensen
Detection And Assay Of Viruses Using Latex Particles, Thomas Charles Sorensen
Electronic Theses and Dissertations
When hemagglutination is caused by the virus particle itself, a particle joins two red blood cells together by forming a bridge between them. If sufficient hemagglutination particles are present, the red cells form clusters of larger aggregates which fall to the bottom of the test tube or well. It is this sort of biophysical phenomenon which is being investigated in this study. Rather than using red blood cells as the adsorbent, to the surface of which the virus adsorbs, some solid adsorbents have been utilized to substitute for the red cells in a variety of experimental manipulations. Bentonite has been …
Classification Error Using Quantized Data, David V. Serreyn
Classification Error Using Quantized Data, David V. Serreyn
Electronic Theses and Dissertations
The ability to make the correct decision is an ability that is perhaps desired by all human beings. Being able to make a correct decision is a function of the amount of information that is available to the decision maker. His ability to make a decision is enhanced by the use of machines specially designed for obtaining information or making decisions such as an electronic computer. Such is the case in the application of pattern recognition to a remote sensing problem. Pattern recognition is defined here as techniques which help distinguish between several classes such that the classification error is …

Comparison Of South Dakota State University Graduates Of The Home Economics And Of Other Curricula With Respect To Family Living Variables, Janice Hofer Grimm
Comparison Of South Dakota State University Graduates Of The Home Economics And Of Other Curricula With Respect To Family Living Variables, Janice Hofer Grimm
Electronic Theses and Dissertations
Marriage and the family as we have known them in the past are currently undergoing greater change at a more accelerated rate than ever before in history. Many writers concerned with the family and social problems would lead us to wonder if marriage is disappearing. There is an increase in communal living, exchange of marriage partners, and "open" campus dormitories. The divorce rate has been climbing steadily for a number of years. But when one looks more deeply into communal life for example, it is discovered that the duration of communal living is generally about two years. A study done …
Comparative Analysis Of Numerical And Integral Methods For Calculating Turbulent Compressible Flow, Ronald James Greve
Comparative Analysis Of Numerical And Integral Methods For Calculating Turbulent Compressible Flow, Ronald James Greve
Electronic Theses and Dissertations
The calculation of boundary layer parameters requires knowledge of the turbulent shear which, with our present incomplete knowledge of turbulence, must rely on empirical relationships. Another well-known problem is the non-linearity of the boundary layer equations. Early calculations rely on the well-known Von Karman integral equations but with the advent of the large digital computers, finite difference methods are presently commonly used. For calculation of the incompressible boundary layer there are two popularly used methods. A comprehensive comparison of this type of approximate method assuming different velocity profiles is given by Taylor. The second is a purely numerical method using …

Estimation Of Plant S And Zn Concentration By Soil Test Correlation, Douglas Darrel Koth
Electronic Theses and Dissertations
Sulfur and Zn are two elements essential for plant growth. Deficiencies of these two plant nutrients occur commonly in many areas of the world. Zinc deficiency symptoms were noted in corn in South Dakota during the late nineteen fifties. In the summer of 1970, S deficiency symptoms appeared in corn (Zea mays L.) grown on sandy soils in Marshall County, South Dakota. Zinc deficiencies of corn occur more often when corn is grown on soils that are characterized by one or more of the following properties: sandy texture, low organic matter, severe past erosion, leveled for irrigation, high lime level, …

Determination Of Salmonella Species In The Big Sioux River And Development Of A Quantitative Most Probable Number Method, Myung Hyun Kim
Electronic Theses and Dissertations
In recent years the pollution problems in rivers and lakes have forced the Federal Water Pollution Control Administration to issue requirements for minimum water standards for each State with an interstate stream. Since the Big Sioux River is an interstate river, studies are needed to determine its quality. According to the South Dakota Committee on Water Pollution, water pollution in South Dakota originates from agricultural, municipal, and industrial wastes. For the Big Sioux River, the municipal and meat-processing wastes are the important sources of pollution. Little is known of the sanitary bacteriological quality of rivers and lakes in South Dakota. …

The Effects Of Identified Student Characteristics On Their Understanding Of Science, Patricia Mutch Cheeseman
The Effects Of Identified Student Characteristics On Their Understanding Of Science, Patricia Mutch Cheeseman
Electronic Theses and Dissertations
This study-was undertaken to try to identify which factors most influence the process of learning science in an ISCS Year I classroom. Because of the breadth of the subject, it has seemed desirable to limit the factors to be considered to those which could be termed "characteristics" of the students. Therefore, recognizing the fact that characteristics alone cannot present the whole picture, occasional mention will be made of other contributing elements. It should be understood that only the characteristics to be named in a later section were included in the statistical analysis. It was expected that no specific student characteristic …

Urban Insurrections: A Multi-Disciplinary Approach Toward An Integrated Typology, James Russell Stewart
Urban Insurrections: A Multi-Disciplinary Approach Toward An Integrated Typology, James Russell Stewart
Electronic Theses and Dissertations
The purpose of this study is to investigate the possibility and appropriateness of employing a multi-disciplinary approach in the study of urban insurrections in an effort to construct a typology which would include all of the elements common to each disorder. The multi-disciplinary method is necessitated by the biases which are inherent in any analysis that is restricted to either a psychological, sociological, or politico-historical treatment of episodes of collective behavior. All of the disciplines make major contributions to any analysis, but it is the contention of this writer that the disciplines must be integrated before the most accurate depiction …
