Geostatistical applications to salinity mapping and simulated reclamation

Creator:: Al-Taher, Mohamad A.
Abstract:: Geostatistical methods were used to find efficient and accurate means for salinity assessment using regionalized random variables and limited sampling. The random variables selected, sodium absorption ratio (SAR), electrical conductivity (EC), and clay content were measured on samples taken over an area of fifteen square miles. Ordinary kriging and co-kriging...

Development of a test procedure for water sensitivity of asphalt concrete mixtures

Creator:: Al-Swailmi, Saleh H.
Abstract:: Environmental factors such as temperature, air, and water can have a profound effect on the durability of asphalt concrete mixtures. In mild climates where good quality aggregates and asphalt cement are available, the major contribution to deterioration may be due to traffic loading and the resultant distress is manifested in...

New bioactive natural products from marine algae and cyanobacteria

Creator:: Sabry, Omar Mohamed
Abstract:: This thesis is an account of investigation on the natural products deriving from various marine algae and has resulted in the discovery of eleven novel bioactive metabolites. Isolation and characterization of these new molecules were carried out using different chromatographic techniques and by analyses of different spectroscopic data, respectively. Using...

Chemical Solution Deposition and in-situ Structural Characterization of Pb-free, Bi-based, Piezoelectric Thin Films

Creator:: Fox, Austin J.
Abstract:: This work explores the electric field induced strain mechanisms in environmentally benign Bi0.5Na0.5TiO3 (BNT) based piezoelectric thin films. Although BNT-based materials show promise as replacements for toxic Pb-based piezoelectrics, the displacement mechanisms are not consistent between thin films and bulk materials, and the differences have yet to be well understood....

A biochemical analysis of the interaction of victorin and oats

Creator:: Navarre, Duroy A.
Abstract:: Victoria blight of oats is caused by the fungus Cochhobolus victoriae. This fungus is pathogenic due to its ability to produce the host-selective toxin victorin. Previously, a 100-kD protein that binds victorin in vivo only in susceptible genotypes was identified as the P protein of the glycine decarboxylase complex (GDC)....

Pathogenicity, Fungicide Resistance, and Genetic Variability of Phytophthora rubi Isolates from Raspberry (Rubus idaeus) in the Western United States

Creator:: Stewart, Jane E., Kroese, Duncan, Tabima, Javier F., Larsen, Meredith M., Fieland, Valerie J., Press, Caroline M., Zasada, Inga A., and Grünwald, Niklaus J.
Abstract:: Root rot of raspberry (Rubus idaeus), thought to be primarily caused by Phytophthora rubi, is an economically important disease in the western United States. The objectives of this study were to determine which Phytophthora species are involved in root rot, examine the efficacy of different isolation methods (cane, root, and...

Partial purification and determination of some properties of an aminotransferase of pea (Pisum sativum L.) plants

Creator:: Matheron, Michael Earl
Abstract:: A transaminase (aminotransferase, EC 2. 6. 1) was extracted and purified approximately 148-fold from shoot tips of pea (Pisum sativum L. cv. Alaska) seedlings and some properties of the enzyme were determined. The purification included acetone precipitation followed by column chromatography on hydroxylapatite. With a-ketoglutarate as co-substrate, the acetone precipitated...

Suitability of diverse composts as soil amendments for highbush blueberry (Vaccinium corymbosum L.)

Creator:: Costello, Ryan C.
Abstract:: Highbush blueberry (Vaccinium corymbosum L.) is adapted to soils with high organic matter and acidic pH. Composts provide organic matter and nutrients for growing blueberry in mineral soils, but many composts are high in pH and soluble salts. Acidification with elemental sulfur (S°) can remedy high pH, but the process...

Aspects of comparative neuromuscular physiology and pharmacology of black bass (Micropterus salmoides) as evidenced by the action of diisopropylfluorophosphate

Creator:: Schneider, Phillip William
Abstract:: Neuromuscular physiology has been extensively investigated in several groups of vertebrates excluding fish. To understand the nature of neuromuscular transmission in this group, the response of the pectoral fin abductor muscle of black bass (Micropterus salmoides) to nerve stimulation under the influence of an anticho1inesterase agent was studied. Diisopropylfluorophosphate (DFP),...
