Cloning Of Lilium Longiflorum And Andropogon Gerardii By Tissue Culture Of Leaf And Floral Parts, Nancy E. Stenberg
Cloning Of Lilium Longiflorum And Andropogon Gerardii By Tissue Culture Of Leaf And Floral Parts, Nancy E. Stenberg
Electronic Theses and Dissertations
The Easter lily, L. longiflorum Thunb. Is known not only for its ornamental value, but also for its large chromosomes, making it ideal cytological material. Big bluestem, Andropogon gerardii Vitman, is a South Dakota native grass. It possesses many desirable characteristics and unique adaptations to this region. This research has primarily dealt with the development of methods for cloning the species L. longiflorum and A. gerardii by tissue culture of leaf and/or floral parts. The pattern of plantlet differentiation from the cultures was also histologically studied.
Purine-Thiamine Anabolism During Cellular Morphogenesis In Myxococcus Xanthus, Wen-Cherng Tsai
Purine-Thiamine Anabolism During Cellular Morphogenesis In Myxococcus Xanthus, Wen-Cherng Tsai
Electronic Theses and Dissertations
Purine-thiamine anabolism during cellular morphogenesis in Myxococcus xanthus was investigated. One of the approaches was to test vegetative and myxospore (2.5 h and 8 h) extracts of M. xanthus CW-2 for their ability to synthesize the second de novo intermediate, 5'-phosphoribosylglycinamide, from beginning precursors either by way of phosphoribosyl-pyrophosphate amidotransferase (EC 2.4.2.14) or ribose-5-phosphate aminotransferase. Results indicate the presence of both the amido- and aminotransferases in both types of extracts, and both enzymes appear to be present at about the same level (per milligram of protein) in vegetative cells, myxospores (2.5 h and 8 h), and in a bacterial prototype, …
Venezuelan Equine Encephalomyelitis Virus Induced Mammalian And Mosquito Cell Volume Changes As Detected With The Coulter Counter, Richard H. Fulker
Venezuelan Equine Encephalomyelitis Virus Induced Mammalian And Mosquito Cell Volume Changes As Detected With The Coulter Counter, Richard H. Fulker
Electronic Theses and Dissertations
The need exists for a detection system which is specific in its diagnosis of viruses. The system presented in this investigation uses antiserum treated virus infected cell cultures to establish specificity. The need exists for an automated virus detection system. The system described in this thesis uses the Boulter Counter, a computer analysis, and a simplified procedure which makes the system suitable and automation. The need also exists for an inexpensive virus detection system. The system proposed in this investigation uses no expensive animal facilities and it will require reduced man-hours. The final need of a virus detection system is …
A Survey Of Why Students Select South Dakota State University Based On The Opinions, Information Sources, And Attitudes Of Entering Students, Vincent O. Heer
A Survey Of Why Students Select South Dakota State University Based On The Opinions, Information Sources, And Attitudes Of Entering Students, Vincent O. Heer
Electronic Theses and Dissertations
The purpose of this study is to examine the information sources, attitudes, and opinions, relevant to the selection process, of the 1975-76 entering students at South Dakota State University to discover what reasons students give for selecting SDSU. It is the hope that this study will reveal important information about the students of South Dakota State University, their attitudes, opinions, and sources of information concerning why they attend. This information is sought so those officials in decision making positions can have a better informational base from which to make important judgements affecting the institution and its component parts. Specifically the …

Morphological, Biochemical And Fluorescent Antibody Studies Of Haemophilus Somnus, Danny W. Chladek
Morphological, Biochemical And Fluorescent Antibody Studies Of Haemophilus Somnus, Danny W. Chladek
Electronic Theses and Dissertations
Haemophilus somnus was the tentative name given in 1969 to a fastidious gram negative pleomorphic coccobacillus which was consistently isolated from cattle affected with a clinical syndrome called thrombo embolic meningoencephalitis (TEME)(1). The organism was initially classidied as an Actinobacillus actinoides- like organism, but because of its demand for a blood base for primary isolationit was reclassified as Haemophilus-like. Bailie then designated the species name somnus, referring to the sleepiness commonly exhibited by TEME affected cattle(1). In this study, the biochemical reactions of 50 H. somnus isolants recovered from bovine specimens submitter to the South Dakota …
The Composition And Dynamics Of The Soil Algal Flora In A Western South Dakota Grassland, Judith Ann Freeman
The Composition And Dynamics Of The Soil Algal Flora In A Western South Dakota Grassland, Judith Ann Freeman
Electronic Theses and Dissertations
Forest, Miller and Raizen (1963) and Hutcheson and Olson (1967) have conducted two of the only investigations on soil algae in a prairie ecosystem. The present investigation dealt first with identification of genera of algae present in the soil and an evaluation of their numbers. Secondarily a relationship was established between the numbers of algae in the soil (by species) and their environment, by the correlation coefficients. The variation in the environment was then used to predict the occurrence of algae in the soil using stepwise additive multiple regression analysis. Finally several environmental factors were evaluated under controlled conditions to …

Infiltration And Hydraulic Characteristics Of A High-Rate Land Application Wastewater System, Donald Jay Voogt
Electronic Theses and Dissertations
Specific objectives of this report are: 1. To describe in detail the construction and operation of the pilot units, 2. To determine the infiltrative capacity and characteristics of the soil in the pilot units in response to the application of stabilization pond effluent, 3. To determine the effect of basin surface cover type on the infiltrative capacity of the soil, 4. To study the response of the natural groundwater table to periodic floodings, and, 5. To evaluate the feasibility of a full-scale land-infiltration system at this location based on the infiltration and hydraulic characteristics of the soil.
Percent Accuracy By Crown Closure Classes Of Woodland Stands Mapped From Skylab-4 Photography And Landsat-1 Imagery, Roger Dale Goldsmith
Percent Accuracy By Crown Closure Classes Of Woodland Stands Mapped From Skylab-4 Photography And Landsat-1 Imagery, Roger Dale Goldsmith
Electronic Theses and Dissertations
LANDSAT-l imagery and satellite photography have been utilized for land-use mapping. This study investigated the correlation between woodland stands mapped and their percent crown closure using LANDSAT-l imagery and Skylab-4 photography. On the basis of percent accuracy of crown closure classes mapped or not mapped, Skylab-4 photography proved superior over LANDSAT-l imagery for mapping woodlands
