The Relationship Between Home Economics Teachers' Conceptual Systems Levels And Classroom Discipline Ideologies, Kathleen R. Winberg
The Relationship Between Home Economics Teachers' Conceptual Systems Levels And Classroom Discipline Ideologies, Kathleen R. Winberg
Electronic Theses and Dissertations
Support for the hypothesis that conceptual systems may be used to predict various teaching behaviors has been established by several researchers (Harvey, 1970; Harvey, et al ., 1966; Murphy and Brown, 1970; Pryor, 1975). Harvey, et al. (1966) recorded and assessed actual classroom teaching behavior of thirty Head Start teachers varying in conceptual level to determine the effects of the teachers' conceptual level on the classroom climate created for their pupils. High, medium, and low conceptual level teachers were rated on twenty-six behavioral dimensions including expression of warmth towards children, enjoyment of teaching, perceptiveness of children’s needs, smoothness of class …
Photoinduction Of Floral Development In Hard Red Winter Wheat, Jose Ernesto Robles Wijangco
Photoinduction Of Floral Development In Hard Red Winter Wheat, Jose Ernesto Robles Wijangco
Electronic Theses and Dissertations
South Dakota is at the northern limit of winter wheat cultivation in the United States. However, it has been estimated that only 15% of the total winter wheat acreage has been planted to hardy winter wheat cultivars in this state. Records at this station indicate that grain yields of winter hardy cultivars can be 20 to 40% lower than less hardy cultivars in the absence of severe freeze stress. Low grain yields of hardy types is one reason for low preference of these phenotypes by growers. Hardy cultivars usually head late compared to less hardy ones. With late initiation of …

Carbon Metabolism Of Azospirillum Brasilense, Galina V. Vigil
Carbon Metabolism Of Azospirillum Brasilense, Galina V. Vigil
Electronic Theses and Dissertations
To understand the nature of bacteria-plant associations both plant and bacterial metabolism studies are important. Research into the biochemistry of photosynthesis has revealed that besides the reductive pentose phosphate cycle, many grasses also possess the C-4 dicarboxylic acid cycle. Grasses possessing this pathway utilize their available nitrogen more efficiently in producing dry matter and fixing atmospheric C02. The general importance of the C-4 dicarboxylic acid pathway in tropical grasses had previously been widely accepted. Azospirillum spp. are thought to be mainly responsible for the nitrogen fixation that occurs in grasses. The preference of these bacteria for malate and other organic …
Bionomics Of The Northern Corn Rootworm On First Year Corn In Eastern South Dakota, Paul M. Vassalotti
Bionomics Of The Northern Corn Rootworm On First Year Corn In Eastern South Dakota, Paul M. Vassalotti
Electronic Theses and Dissertations
The northern corn rootworm, Diabrotica longicornis barberi, is a major pest of corn in South Dakota. It has one generation per year and overwinters in the soil as an egg. The eggs hatch in June and the larvae begin feeding on developing corn roots. The loss of roots reduces the uptake of water and nutrients, which can reduce yields especially under dry conditions. Root pruning by the larvae also weakens the brace root system, which may cause the plant to lodge, making harvesting difficult. Corn is the preferred host plant, although larvae have been reported surviving on several other species …

Genetics Of Resistance To Hessian Fly Derived From Dawn Winter Wheat In Spring Wheat Crosses, Debra Kay Steiger
Electronic Theses and Dissertations
Hessian fly, Mayetiola destructor (Say), has been a serious insect pest of cornnon wheat (Triticum aestivum L. em Thell.) since it was first identified in the United States over 200 years ago. Losses are difficult to estimate due to geographical variability in populations but are large enough to characterize this pest as one of economic importance. Dahms in 1967 estimated the direct average annual loss in the United States at 15 million bushels. The last serious outbreak in the United States was reported in 1978 in the spring wheat producing regions of north central and northeastern South Dakota where conservative …

The Effect Of Photoperiod On Reproduction Of Targhee Ewes, Richard D. Rogen
The Effect Of Photoperiod On Reproduction Of Targhee Ewes, Richard D. Rogen
Electronic Theses and Dissertations
Seasonality of reproduction in sheep has created an oscillating supply of lambs. A more constant supply of lambs would allow more efficient use of facilities and labor by producers, feedlots and packing plants. Seasonal reproduction also limits the lifetime production of the ewe. Extension of the breeding season would provide a more consistent supply of lambs. In addition, more than one lamb crop per ewe could be produced annually. Not only the yearly lamb production but also the lifetime production of the ewe would then be increased. Also, the generation interval would be shortened allowing faster herd improvement. It is …

The Cary ground moraine forms the western edge of the Coteau des Prairies. It is characterized by numerous lakes, small closed depressions and poorly drained swales. The soils which occur on the footslopes adjacent to the closed depressions and poorly drained swales often contain calcium carbonates and other soluble salts at or near the surface. An in situ investigation of the morphology and genesis of these calcium carbonate enriched soils was undertaken to determine their genesis and classification. An area in which these soils occur was selected for study and a series of observation wells were installed to monitor the …
Relationship Between Soil Moisture And Soil Surface Temperature, Steven Darwin Ness
Relationship Between Soil Moisture And Soil Surface Temperature, Steven Darwin Ness
Electronic Theses and Dissertations
Thermal-infrared imagery (thermography) obtained from satellite altitudes has been shown to be a promising new tool for resource management and development. Satellite-borne thermal-infrared sensors allow the collection of time-sequential thermal-infrared radiation (thermal emittance) data over large land surface areas of the earth at relatively low cost. Thus, any resource which can be related to thermal emittance can be readily monitored. Thermal emittance from a surface is proportional to the fourth power of the surface temperature. Thus any factor which affects the surface temperature greatly affects the surface thermal emittance. · Moisture is such a factor when the land surface is …
Nitrogen Fertility Requirements, Dry Matter Production And Nutrient Uptake Of The Sunflower, Robert Andrew Narem
Nitrogen Fertility Requirements, Dry Matter Production And Nutrient Uptake Of The Sunflower, Robert Andrew Narem
Electronic Theses and Dissertations
Sunflower (Helianthus annuus L.) has recently become a major crop in the north-central United States. This is the result of the development of high yielding oilseed hybrids, a steadily expanding export market and the plant's inherent adaptability to severe weather conditions. During the early part of this century research was conducted throughout the nation investigating sunflower's potential for silage. As farmer interest declined, the crop was almost forgotten until the introduction of high oil cultivars from the Soviet Union where sunflower had been grown for oil since the mid-1700's. The discovery of cytoplasmic male sterility and fertility restoration then made …
Plants Poisonous To Livestock In Botswana, Pearl Dijeng Motsepe
Plants Poisonous To Livestock In Botswana, Pearl Dijeng Motsepe
Electronic Theses and Dissertations
Livestock plant poisoning is very common in Botswana. Two plants, Dichapetalum cymosum and Pavetta harborii, are especially notorious for causing large-scale mortality in some areas of the country. In 1975, for instance, a D. cymosurn poisoning outbreak killed 210 cattle in east central Botswana. In the same year P. harborii caused large-scale deaths of cattle in the Mochudi area. The losses caused alarm among livestock farmers and the problem was among the issues discussed in the 1975 session of the Botswana Parliament. Because of their potency, farmers in South Africa refer to these species as "sudden death 11 plants. Unlike …

The Effects Of Dynamic Range Of Motion Exercises And Static Stretching On Strength And Range Of Motion Of The Hip Joint, Carol A. Kanetzke
Electronic Theses and Dissertations
Efficiency of movement is dependent upon norm ranges of motion. Physical educators and physical therapists, therefore, have done a considerable amount of research in developing effective programs through which flexibility can be gained. It is a commonly and generally recognized belief that flexibility is an important factor in human performance, as well as an essential component of physical fitness. Evidence indicates that maintenance of good joint mobility decreases the incidence of injuries in athletics, and consequently is of concern to the physical education profession. Numerous stretching techniques have been developed to produce greater range of movement in joints, and have …
The Effect Of Nitrogen Fertilization On Grain Protein Content And Yield Of Spring Wheat In South Dakota, Syed Dara Tazul Islam
The Effect Of Nitrogen Fertilization On Grain Protein Content And Yield Of Spring Wheat In South Dakota, Syed Dara Tazul Islam
Electronic Theses and Dissertations
It has been predicted that the cost of nitrogen fertilizer will soon triple. Consequently, N management by wheat growers in South Dakota will be even more critical than it has been in the past. Nitrogen is one of the most limiting nutrients for wheat production in South Dakota. Many of the spring wheat producers fail to take advantage of nitrogen fertilizer recommendations based on soil testing. Therefore, it is likely that a simple post-harvest method of determining if adequate N was present for wheat crop would be very beneficial to spring wheat producers. One such method is using grain protein …
Adjusting Potential To Actual Evapotranspiration Rates Applicable Over Large Spatial Regions, Leah Jane Horton
Adjusting Potential To Actual Evapotranspiration Rates Applicable Over Large Spatial Regions, Leah Jane Horton
Electronic Theses and Dissertations
Because of their repetitive flight patterns and broad spatial coverage, satellites hold great promise for supplying the data necessary to predict soil moisture conditions. Already satellite data have been used to predict such input parameters to soil moisture models as solar radiation values and leaf area indices. In addition, surface soil moisture or rainfall events could be detected remotely and used as model inputs. Conceivably, satellite imagery could be used to. predict most, if not all, of the inputs into a soil moisture model. Although the use of satellite data sounds like a timely panacea, there are some inherent questions …

The Effects Of Excess Arginine On Lysine Utilization In Rats And Swine, David L. Hagemeier
The Effects Of Excess Arginine On Lysine Utilization In Rats And Swine, David L. Hagemeier
Electronic Theses and Dissertations
The objective of adding supplemental protein to swine diets is to provide the levels of available essential amino acids and nitrogen necessary for maximum protein synthesis in the pig. Lysine has been determined to be the limiting amino acid in many swine diets. Thus, the real objective of protein supplementation is to provide the amount of lysine necessary for maximum protein synthesis, and if this objective is met the requirements for the other essential amino acids and nitrogen will generally be met. Since swine diets are formulated to meet the lysine requirement of the pig, it is necessary to derive …

Farm-Scale Production Of Fuel Ethanol And Distillers' Wet Grains From Corn And Corn-Whey Mixtures, William Ray Gibbons
Electronic Theses and Dissertations
Since the Arab oil embargo of 1973, we have become increasingly aware of the finite nature of our petroleum supplies. Current studies estimate that our supplies of petroleum will be depleted in the next 25 to 50 years. As supplies diminish and prices rise, we will need alternate forms of energy to take up the slack. One of the leading alternatives is the use of biomass in the production of liquid fuel that is, conversion of cellulose, starch, glucose, or other carbohydrates to ethanol. In the United States, the fuel ethanol industry is still in its infancy. Approximately a dozen …

The Forgotten Realist, John Garvey
Electronic Theses and Dissertations
Today the name "Hoosier" can be applied to anybody living in or coming from the state of Indiana. Many Americans first hear it as the name of Indiana University's athletic teams; tourists become familiar with the "Hoosier State" nickname which appears on interstate highway signs, travel brochures and maps. Because of the popularity ofc Kurt Vonnegut’s books in recent years, many of us have first learned the term in his work. Others think of it as a name for the landscape of James Whitcomb Riley's verse. And there are still alive some older folk among us who, like students of …
