Services, Practices, Characteristics And Other Factors Affecting A Farmer's Selection Of A Farm Supply Or Marketing Firm, Karla Jean Nelson Kraner
Services, Practices, Characteristics And Other Factors Affecting A Farmer's Selection Of A Farm Supply Or Marketing Firm, Karla Jean Nelson Kraner
Electronic Theses and Dissertations
The difference between success and failure of a business can often be attributed to whether or not the customer is served in the manner he or she wants. Therefore, it is very important for farm supply and marketing firms to know what services, practices and products their customers want and to do all within reason to serve those needs. Sometimes distinctions must be made between customer wants and customer needs and sometimes it is not reasonable to try to serve every nee, but most of a customer’s needs must be met or he or she will shop elsewhere. This is …
Design And Testing Of A Solar Energy-Intensifier For Drying Shelled Corn, Steven E. Saienga
Design And Testing Of A Solar Energy-Intensifier For Drying Shelled Corn, Steven E. Saienga
Electronic Theses and Dissertations
Agricultural crop drying provides numerous applications where low to moderate temperature rises can provide a large percentage of the grain drying requirements. The application of solar energy to grain drying depends on the capability of the solar energy system to provide temperature rises and enough heat to increase the rate at which moisture is removed from the wet grain. Current investigations of solar energy utilization for agricultural applications include many variations of solar collectors and solar concentrators. However, data available on the use of solar concentrators for specific agricultural applications in most climatic areas are limited. Because of the great …
Winter Operating Constraints Of A High-Rate Infiltration-Percolation Treatment System For Wastewater, Eugene A. Miller
Winter Operating Constraints Of A High-Rate Infiltration-Percolation Treatment System For Wastewater, Eugene A. Miller
Electronic Theses and Dissertations
In order to comply with the federal Water Pollution Control act Amendments of 1972, many small communities in South Dakota are faced with the probability of having to update the quality of wastewater that is being discharged. Many of these communities presently use low-cost lagoons or stabilization ponds that provide various degrees of wastewater treatment. With lack of trained personnel for routine operation and maintenance and the inherent financial problems due to a limited tax base, small communities have a definite need for a simple and inexpensive form of wastewater treatment that ill upgrade effluents from stabilization ponds to meet …
Solar Energy For Supplemental Heating Of Livestock Buildings, David P. Yexley
Solar Energy For Supplemental Heating Of Livestock Buildings, David P. Yexley
Electronic Theses and Dissertations
The cost of energy spans a wide range at various geographic locations, Solar energy has not generally been competitive with other energy sources because of high initial capital costs per unit of energy return for most collector systems. These costs must be justified so that the benefits of the virtually free primary fuel source can become economically attractive. Therefore the objectives of this study were established as follows: 1. Design and compare the efficiencies and total energy supplied by three types of low cost, low temperature rise bare plate solar collectors. 2. Evaluate the performance of solar collectors that can …
Dick And Jane Grow Up : Trends In Fiction For Young Adults, Nancy Veglahn
Dick And Jane Grow Up : Trends In Fiction For Young Adults, Nancy Veglahn
Electronic Theses and Dissertations
The YA novel may be defined, then, as a work of fiction intended and published especially for readers between the ages of thirteen and eighteen. The distinction is to some degree an artificial one created by the realities of publishing. If a book is purchased by the juvenile division of a publishing company, it is presented as a YA novel. The same book might conceivably have been bought and published by the adult division of the same company, in which case it would be considered an adult book. There is some crossing back and forth across these artificial barriers. YA …

The Use Of Plant Tissue Culture Techniques For Studying The Growth Of Morel, James Wassom
Electronic Theses and Dissertations
Like all mushrooms, the morel mushroom is a fungus. Morels are the fruiting bodies produced by members of the genus, Morchella, Morels are often considered to be a class with truffles by mushroom hunters. Unlike other mushrooms, the morel is not toadstool shaped, but looks like a sponge on a stalk, this makes it easy to identify. There are no poisonous mushrooms that resemble morels. Morels are widely distributed. Morels are known to occur in North America, Europe, and Israel. They are found in a wide variety of topographies, from mountains to plains. They can be found on grasslands, orchards, …

Probabilities Of Solar Weather, Hand-Hung Chen
Electronic Theses and Dissertations
During the last several years we have witnessed increasing costs and shortages of energy from conventional sources. This “energy crisis” promises to be with us for some time to come unless we change our way of life and in addition develop new sources of energy. The energy crisis is spurring the development of several new energy have been considered including heating and cooling of homes, domestic hot water heating, drying of agricultural products and many more. The economic feasibility of a solar system depends upon how well the system perform in the particular location in which it is to be …
Attitude Changes In College Women Resulting From A Four Year Program In Child Development And Family Relations, Judy Youngbauer Branum
Attitude Changes In College Women Resulting From A Four Year Program In Child Development And Family Relations, Judy Youngbauer Branum
Electronic Theses and Dissertations
The purpose of the study was to determine the attitude changes in females resulting from the four year Child Development and Family Relations (CDFR) program at South Dakota State University. If this program of study has an effect upon students’ attitudes, then there should be measurable differences between the attitudes of students beginning the CDFR program and the attitudes of those finishing the CDFR program. In order to demonstrate that a change in attitudes was due to this particular program, it was necessary that beginning and graduating students in other programs of study be tested and used as comparative groups.

Control Of Phomopsis Blight Of Eastern Redcedar With Benomyl, Douglas J. Fiedler
Control Of Phomopsis Blight Of Eastern Redcedar With Benomyl, Douglas J. Fiedler
Electronic Theses and Dissertations
Control of Phomopsis blight (P. juniperovora) of eastern redcedar (Juniperus virginiana) with benomyl was investigated using potted seedlings in a greenhouse. Benomyl sprays and drenches did not prevent infection. However, three pre-inoculation foliar sprays (600 ppm a.i.) applied at weekly intervals followed by three post-inoculation sprays gave significant control of disease progression. Benomyl drenches of 0, 6.5, 13, 40, 80, 160, 320 and 640 mg/liter pot resulted in significant blight control with the 40 to 640 mg treatments. Thin layer chromatography coupled with Penicillium bioassay determined that 3 μg of benomyl (MBC)/g plant tissue (fresh weight) was the minimal concentration …
Inheritance Of Regrowth And Other Characters In Smooth Bromegrass, Geprge Lance Holborn
Inheritance Of Regrowth And Other Characters In Smooth Bromegrass, Geprge Lance Holborn
Electronic Theses and Dissertations
Land utilization is becoming increasingly important; farmers and ranchers are continually striving to produce more from production sites and to realize some production from their presently non-productive areas. Progress in this direction must be forthcoming in all areas of agriculture. In the case of cool-season grass species, growth takes place in the spring and fall of the year. With the exceptions of the cool-season grass species, orchardgrass, Dactylis glomerata L., little if any mid-summer growth is produced. Orchardgrass, however, is not winter-hardy or very productive under dryland conditions in South Dakota. Currently, there are no cool-season grass varieties recommended to …

A Leptospirosis Survey Of Small Mammals In Brookings County, South Dakota, Raymond Elton Kiewit
Electronic Theses and Dissertations
Small mammals from western Brookings County, South Dakota were collected and examined for leptospirosis. The major methods used were the microscopic agglutination test and darkfield examination of urine for spirochetes. From 32 sites, a total of 248 animals were collected from which 73 (29.4%) serum samples and 82 (33.1%) urine samples were obtained. Spirochetes were observed in the urine of 3 deer mice (Peromyscus maniculatus). One of the deer mice had spirochetes in the urine and agglutinating antibodies to L. wolfii in the serum. One thirteen-lined ground squirrel (Spermophilus tridecemlineatus) had an agglutination titer of 1:10 to L. Hardjo, and …
