Spatial Perception As A Predictor Of Success In Higher Mathematics, Lou A. Rolen
Electronic Theses and Dissertations
The problem of this study was to determine if spatial perception could be a predictor of success in higher mathematics. This study first showed correlations of the results of three spatial perception tests taken by high-school students with their final geometry grades. Structure of the Intellect-Learning Ability subtests CFS (cognition of figural systems) and CFT (cognition of figural transformations), as well as Differential Aptitude Tests-Space Relations subtest, were used. Correlations were then computed for high-school geometery grades with calculus I grades. Geometry thus was used as a bridge between spatial perception and calculus performance. Secondly, the investigator explored any difference …
The Effects Of Biological Type And Breed Composition On Production In Beef Cattle, Michael D. Monfore
The Effects Of Biological Type And Breed Composition On Production In Beef Cattle, Michael D. Monfore
Electronic Theses and Dissertations
Evaluation of breeds has developed beyond simple phenotypic performance comparisons to estimation of the various genetic components, additive and nonadditive, contributed by a breed (Dickerson ,1969). Alenda et al.; Dillard et al. and Robison et al. demonstrated methods for estimating breed genetic and maternal effects in crossbred populations. Alenda and Martin extended the use of regression models to allow estimation of optimal breed combinations. This procedure, based on work by Dickerson, involves construction of a mathematical model describing performance for a trait as the sum of breed additive, breed heterotic, breed maternal and maternal heterotic effects. Crossbreeding results have been …

Evaluation Of Gravel Excavation On Ground Water Movement And Quality, Nilaksh Kothari
Electronic Theses and Dissertations
The resource ground water is used by nearly one-half the nation's population for drinking purposes, and 70% of all ground water used is for irrigation. Yet, surprisingly protection of the ground water resource is not covered by a single federal act. Consequently, ground water is a subject of widespread misconceptions. These misconceptions have adversely affected the development, conservation and quality of the ground water. In the mining areas detailed information on the hydrologic environment is needed due to recent mining regulations. In Brookings county of South Dakota, large scale gravel excavations have occurred during the last twenty years. These excavations …

It is an important species for livestock in the Great Plains, producine its greatest growth in the hot summer months when cool-season species are nonproductive. As it is native to the Great Plains region, it exhibits ecotypic adaptability and forage production potential over a wide range of environmental and growing conditions. Because of its rhizomatous growth habit and fibrous root system, it is also useful. for soil conservation purposes. One of the problems associated with establishing native …
Plasma Pepsinogen Test For Hypobiotic Nematode Larvae In Abomasal Glands Of Sheep, Richard Alex Jensen
Plasma Pepsinogen Test For Hypobiotic Nematode Larvae In Abomasal Glands Of Sheep, Richard Alex Jensen
Electronic Theses and Dissertations
The American Association of Veterinary Parasitologists reported that nematodes in sheep represent an unquestionably great production loss, and that the absence of deworming on a routine basis would hamper modern sheep production. After ingestion, the infective third stage larva, or L3, exsheaths and burrows into the digestive glands, and becomes a fourth stage larva, or L4. According to Armour, 18 to 21 days after L3 ingestion occurs, the nematode reaches sexual maturity. However, while in the gastric glands, these L4 invade the parietal, or hydrochloric acid (HCl) secreting cells, damaging them, and replacing them with non-acid secreting cells. This leads …

Wildlife Response To Stand Structure Of Green Ash Woodlands, Robert A. Hodorff
Electronic Theses and Dissertations
Vegetation, birds and mammals were sampled over two years in two types of green ash woodlands in extreme northwestern South Dakota. Woodlands referred to as closed canopy stands consisted of dense stands of various species of trees and shrubs in different size and age classes. Woodlands referred to as open canopy stands had sparse stands of older trees, with intermediate seedling, sapling and tall shrub layers nearly absent. Closed stands had significantly greater (P = .002) coverage of shrubs in the understory than open stands while open stands had significantly greater (P = .004) total coverage of grasses than closed …
Evaluation Of Seasonal Habitat Use By White-Tailed Deer In Eastern South Dakota, Thomas James Kramlich
Evaluation Of Seasonal Habitat Use By White-Tailed Deer In Eastern South Dakota, Thomas James Kramlich
Electronic Theses and Dissertations
Seasonal use of selected habitat types by white-tailed deer (Odocoileus virginianus) was investigated using radio telemetry locations during 1983 and 1984, on a predominantly agricultural area in east-central South Dakota. In the summer of 1983, radio-collared deer used corn, shelterbelts, and wetlands in proportion to their availability. Soybeans, grainfields, and grasslands were avoided. Deer selected shelterbelts in the fall and wetlands during the winter months, for protective cover. Habitat use shifted in the spring and shelterbelts received heavy use, once they became free of drifted snow. Shelterbelts continued to be selected by deer during the summer of 1984. IN the …

Effectiveness Of Shelterbelts In Improving Microclimatic Conditions For Pheasants In Eastern South Dakota, Todd Matthew Schneider
Electronic Theses and Dissertations
To evaluate wintering habitat for ring-necked pheasants (Phasianus colchicus), this study compared microclimate regimes , as determined by wind and temperature, between shelterbelts containing 1 or 2 rows of coniferous tree species with shelterbelts comprised entirely of deciduous tree species and between wetland and shelterbelt habitats. Maximum temperatures within both shelterbelt types, particularly deciduous shelterbelts, were cooler than outside ambient air temperature during summer. Throughout November, December, and January, minimum temperatures in coniferous shelterbelts types were significantly (P≤0.04) warmer than deciduous shelterbelt types. Effectiveness of shelterbelts in reducing wind velocity decreased from an average of 71% during summer to 28% …
Photovoltaic Investigations Utilizing Stannic Oxide Single Crystals, Teresa L. Hein
Photovoltaic Investigations Utilizing Stannic Oxide Single Crystals, Teresa L. Hein
Electronic Theses and Dissertations
The energy crisis of the 1970's led to a considerable research effort in typical p-n junctions used in solar cells. However, there are several other types of photovoltaic effects worthy of investigation. Two of these effects are of particular interest to this study. One of these is the Dember photovoltaic effect. This effect occurs in the bulk of the semiconductor and arises from the differences in hole and electron mobilities. It requires a semiconductor with metal contacts exposed to light which is nonuniformly distributed. A second type of photovoltaic effect of particular interest is that which occurs in Schottky-barrier devices. …
Lungworm Infections, Reproduction And Summer Habitat Use Of Bighorn Sheep In Custer State Park, South Dakota, Gary C. Brundige
Lungworm Infections, Reproduction And Summer Habitat Use Of Bighorn Sheep In Custer State Park, South Dakota, Gary C. Brundige
Electronic Theses and Dissertations
Bighorn sheep (Ovis canadensis) were once indigenous to the Black Hills and Badlands of South Dakota. When European settlers moved into this region during the late 1800' s, market hunting, loss of habitat, and introduction of animal diseases and parasites caused the subspecies of the region, the Audubon's bighorn sheep (O. c. auduboni), to become extinct by 1916 (Buechner 1960). To reestablish bighorn sheep in the Black Hills, 8 Rocky Mountain bighorn sheep (O. c. canadensis) were introduced into the former range of the Audubon's sheep in 1922. Finding the habitat to be very suitable, this small population increased to …

Efficiency Of Two Black-Tailed Prairie Dog Rodenticides And Their Impacts On Non-Target Bird Species, Anthony Dean Apa
Electronic Theses and Dissertations
In 1983 zinc phosphide, strychnine with prebait, and strychnine without prebait were applied to black-tailed prairie dog (Cynomys ludovicianus) colonies in west-central South Dakota. Short-term (4 days later) and long-term (1 year later) poison efficiency and impact (short-term and long-term) on horned larks (Eromophila alpestrus) and other seed-eating birds of the prairie dog colonies were evaluated. Prairie dog burrow densities ranged from 54-187 burrows/ha with an average burrow density of 114 ±8 (± SE) burrows/ha. Rodenticide short-term control reduced active burrows by 95% with zinc phosphide, 42% with only strychnine, and 78% with prebaited strychnine. More zinc phosphide was consumed …
