Interaction of Microwaves and Germinating Seeds

Description: This investigation was concerned with determining the interaction of microwaves with germinating seeds. This study covers two different approaches. The preliminary efforts covered the response of germinating seeds to treatment by microwaves and heat. The second phase of the investigation used microwaves as a probe to determine some of the processes of early seed germination. The preliminary investigation measured the internal metabolic process by ATP production. Leakage of ions and organic mate… more

Studies on Hog Plasma Lecithin:cholesterol Acyltransferase: Isolation and Characterization of the Enzyme

Description: Lecithin:cholesterol acyltransferase (LCAT) was isolated from hog plasma and basic physicochemical properties and functionally important regions were investigated. Approximately one milligram of the enzyme was purified to apparent homogeneity with approximately a 20,000-fold increase in specific activity. In the plasma, hog LCAT was found to associate with high-density lipoproteins (HDL) probably through hydrophobic interactions with apolipoprotein A-I. HDL was the preferred lipoprotein substra… more

Invertible Ideals and the Strong Two-Generator Property in Some Polynomial Subrings

Description: Let K be any field and Q be the rationals. Define K^1[X] = {f(X) e K[X]| the coefficient of X in f(X) is zero} and Q^1β[X] = {f(X) e Q[X]| the coefficent of β1(X) in the binomial expansion of f(X) is zero}, where {β1(X)}^∞ i=0 are the well-known binomial polynomials. In this work, I establish the following results: K^1[X] and Q^1β[X] are one-dimensional, Noetherian, non-Prüfer domains with the two-generator property on ideals. Using the unique factorization structure of the overrings K[X] and Q… more

A Behavioral Modification Analysis of the Effects of Multimedia First Aid Training on Injuries in an Industrial Setting

Description: Past research has shown a correlation between first-aid training and the reduction of injuries. This connection has been noted in off-the-job situations in addition to industrial studies. This project is an extension of those past findings with three notable differences: total population training was studied, as the intervention instead of just saturation treatment; attention was given to the effect that the half-life of training had upon injury reduction; and three randomly chosen small groups… more

Two Photon Resonant Picosecond Pulse Propagation in Lithium Vapor

Description: The work of this dissertation has been to prove that the coherence of multiphoton excitation can be studied by an appropriately phased and time delayed sequence of pulses. An application of this fundamental study of coherence has been made for the enhancement of third harmonic generation. The coherent recovery of the energy lost to the two photon absorption process enalled a larger propagation distance for the fundamental than in an interaction which is incoherent or coherent, but not using a … more

Dispute Resolution Studies in the Institutions of Higher Learning: an Initial Investigative Study of Professors' Attitudes

Description: Conflict is present in all human relationships and societies. Throughout history, fighting has been more notable than peacemaking. Only recently have conflict resolution studies entered the mainstream of academia. Since peace is no longer an option, but a necessity, educators must become actively engaged in promoting the importance of peacemaking skills among their students. In 1986, the National Institute for Dispute Resolution funded a study of conflict resolution in higher education. Results… more

Model Development for the Catalytic Calcination of Calcium Carbonate

Description: Lime is one of the largest manufactured chemicals in the United States. The conversion of calcium carbonate into calcium oxide is an endothermic reaction and requires approximately two to four times the theoretical quantity of energy predicted from thermodynamic analysis. With the skyrocketing costs of fossil fuels, how to decrease the energy consumption in the calcination process has become a very important problem in the lime industry. In the present study, many chemicals including lithium ca… more

Life History Biology of the Desert Nesting Seagull Larus modestus

Description: Gray gulls Larus modestus are unique among birds of northern Chile as the only species nesting in the interior Atacama Desert, and the only seagull nesting far (30 - 100 km) from surface water.
