The Occurrence And Effects Of Entomophaga Grylli On Grasshopper Populations In South Dakota, Roger Allen Bohls

Electronic Theses and Dissertations

The effect of Entomophaga grylli on grasshopper populations within South Dakota was investigated during a 2-year period. Field observations established that the state's 3 most important species of grasshoppers are susceptible to pathotype 2 infections. Outbreaks are believed to be initiated annually from the soil of undisturbed areas which act as the reservior for Entomophaga grylli resting spores. The occurrence of the fungus in regions of the state receiving 355 mm of rain during the growing season indicate pathotype 2 infection is maintained in dry environments. However, detailed epizootiol ogical studies of the fungus are needed before the potential of …

The Determination Of Lead By Electrothermal Atomic Absorption Spectrocsopy : A Study Of The Molecular Interferences, Ahmed Elsayed Abdelfattah

Electronic Theses and Dissertations

The presence of interference effects in atomic absorption spectroscopy affects the degree of accuracy that can be obtained. A major source of interference in electrothermal atomization processes appears to involve the formation of molecular species. In the analysis of lead in the presence of chloride, three peaks are observed. The first of these peaks has an absorption spectrum characteristic of lead chloride. The second and third peaks cannot be identified on the basis of their respective spectra. In the presence of nitrate, the analysis of lead results in the presence of a broad band absorption profile that cannot be identified. …

George Herbert : His Method, Salesian Or Protestant, Bruce Aardsma

Electronic Theses and Dissertations

In modern times literary criticism has seen a renewed interest in the poetry of the seventeenth century metaphysical poets, commonly referred to as ''the poetry of meditation." Based on the Augustinan philosophy, the act of meditation became a devotional process through which a person could attain a union with the Godhead by following a prescribed method. This method included the stages of purgation, illumination, and unification, through which the meditant first becomes aware of his own sinful nature and hopeless condition and then discovers the way of salvation and commits himself to the service of God. The final stage of …

Performance And Evaluation Of A Variable-Speed Darrieus Wind Turbine, Kasey W. Abbott

Electronic Theses and Dissertations

Developing wind energy suitable for agriculture applications is a critical step towards providing a reliable, affordable energy supply for United States agriculture. United States agriculture, due to its energy intensive nature-, is dependent on petroleum fuels. Because agriculture is extremely sensitive, to supply interruptions, steps must be taken to reduce this dependence on oil, including developing wind energy systems. It appears that the potential is there since winds over the United States contain more than 30 times the total energy consumed in this nation (Soderholm, 1979).
Agricultural applications (e.g. irrigation pumping, product processing and building heating) are uniquely suited to …

Assessment Of The Impact Of The European Corn Borer At Three Locations In South Dakota, David R. Raemisch

Electronic Theses and Dissertations

The European corn borer (Lepidoptera: Pyralidae) varies as an

economically significant pest in South Dakota from south to north. In

the northern part of the state the European corn borer (ECB) is limited

to one generation per year. In contrast, there are localized sites

along the Missouri River in southern South Dakota which usually

experience a substantial second brood population. Infestation by

either first or second brood ECB occurs at different stages in the

developmental sequence of the corn plant. As such, each brood must be

considered separately when assessing relationships between yield loss

and ECB larval cavities within the …

Emily Dickinson's Poetry : Abnormality Defined, Izzat Mohammed Ghazzawi

Electronic Theses and Dissertations

As a romantic poet, Emily Dickinson was fascinated by nature, individualism, man's relation with God and the universe and the other unperceivable problems of love, pain and death. Emerson and Thoreau dwelt on "Transcendentalism” with great enthusiasm; they were absorbed in their pilgrimage into nature and with man's place in this ambiguous universe. Melville's literary interests revealed the tensions that existed in his mind and in the culture at large--tensions set up by the conflict between the will to believe and the need to be shown, between transcendentalism and empiricism in philosophy, between religion and science. Whitman was content with …

Growth Hormone Variability And Its Predictive Value In Beef Females, Thomas W. Lingscheit

A Short-Run Economic Analysis Of Some Factors Influencing The Supply Of Beef-Cattle At Auctions In South-Eastern Botswana, 1976-1980, Kene Patrick Cyril Sinombe

Electronic Theses and Dissertations

Auction sales provide a major cattle marketing outlet for farmers in Botswana. There were 5,740 cattle auctioned in the South-eastern part of Botswana in 1976. This number represented 16% of the total export off-take from the area. The main market outlet for slaughter beef is through direct marketing of cattle to the Botswana Meat Commission (BMC) abattoir. The BMC, an export monopoly beef marketing board, sets prices and cattle buyers country-wide adjust them to derive producer prices, because they finally sell cattle to the BMC. The BMC price plays a major role in deriving producer prices at auction sales yards. …

Radium-226 Detection By Radon Emanation And Rapid Simultaneous Scintillation Counting Methods, Richard Dean Wittmeier

Electronic Theses and Dissertations

Since its beginning the universe has been contaminated with a host of radioactive isotopes. Of these radioactive isotopes, many have completely decayed away due to their short half-lives. The remaining naturally occurring isotopes are members of long decay chains such as uranium-238, uranium-235 and thorium-232. The natural background radiation in the environment is primarily due to the decay of these remaining isotopes. This background radiation is normally harmless to the existance of life unless concentrated amounts are received. Because of its chemical compatibility with calcium, radioactive radium isotopes are the most health hazardous of all naturally occurring isotopes. Radium chemically …

Genetic Correlations Among Sex-Limited Traits, Michael D. Macneil

Electronic Theses and Dissertations

Monte Carlo simulation techniques were used to assess the merits of three methods for calculation of the genetic correlation when traits have been measured on half-sibs of each sex. The restricted maximum likelihood, path coefficient and covariance component estimators did not differ significantly in their accuracy. Path coefficient and covariance component methodologies gave nearly unbiased estimators for traits of high heritability. Across both levels of heritability, the restricted maximum likelihood methodology resulted in genetic correlations being estimated with significantly smaller sampling variance than the other methods. Genetic correlations were estimated for age of puberty, weight at puberty, conceptions per service, …
