Severe localized corrosion was found throughout an aeration tank of a modular wastewater treatment plant. Specifically, pitting, crevice corrosion, galvanic corrosion, and intergranular corrosion (IGC) were observed on the 5000 and 6000 series aluminum alloys used in the tank’s construction. One...
Exploring the role of the thioredoxin system, peroxiredoxins and glutaredoxins in aluminum and cadmium tolerance in yeast and Arabidopsis thalianaDownload
Aluminum (Al) and cadmium (Cd) are non-redox active metal ions of agricultural importance. Both are able to induce oxidative damage as a mechanism of toxicity. To increase our understanding of the mechanisms of Al and Cd toxicity and tolerance in plants, the potential role of antioxidant enzymes...
This thesis focuses on fabrication of aluminum matrix composites using friction stir processing. Al 5059 alloy was selected as the matrix alloy, and the effect of processing parameters on microstructure and mechanical properties of this alloy was studied in detail. Friction stir processing was...
Mechanisms of Aluminum Tolerance in Triticum aestivum L. (Wheat). I. Differential pH Induced by Winter Cultivars in Nutrient Solutions.Download
Twenty winter cultivars of Triticum aestivom L. (wheat) were grown in solution culture with and without aluminum (A1) (74 gM, 2.0 mg L-') for 14 days. Exposure to s increased root growth of the most tolerant cultivar, while both root and shoot growth were depressed in all other cultivars. On the...
Mechanisms of Aluminum Tolerance in Triticum aestivum L. (Wheat). II. Differential pH Induced by Spring Cultivars in Nutrient Solutions.Download
Twenty spring cultivars of Traticum aestivum L. (wheat) were grown in solution culture with and without aluminum (A1) (74 gM, 2.0 mg L-l) for 14 days. Root growth and shoot growth were depressed in all cultivars grown with A1; however, symptoms of A1 toxicity were most evident on roots. Based on...
We examined the production of high-surface area anodized porous aluminum (Al) oxide within a micro-scale channel. A potential surface modification using an initial layer of oxidized tantalum (Ta) was also studied. Channels were etched into a layer of silicon dioxide on silicon wafers (groups of...
The aluminum-in-olivine thermometer for mantle peridotites — Experimental versus empirical calibration and potential applicationsDownload
This study provides an experimental calibration of the empirical Al-in-olivine thermometer for mantle peridotites proposed by De Hoog et al. (2010). We report Al concentrations measured by secondary ion mass spectrometry (SIMS) in olivines produced in the original high-pressure, high-temperature,...
Class III peroxidases have been identified as secreted proteins involved in plant defense, auxin metabolism, cell wall modification, and regulation of reactive oxygen species. Transcriptome analysis of Arabidopsis has identified many class III peroxidases that respond to aluminum stress. The...
Transcriptome and Proteome Based Survey to Identify Aluminum-Responsive Genes in Roots of Arabidopsis ThalianaDownload
Aluminum (Al)stress is a major limitation to crop productivity on acidic soils. To help understand the cellular mechanisms underlying the toxicity and resistance of plants to Al, this thesis involved a large-scale, transcriptomic and proteomic analysis of roots of Arabidopsis thaliana and reports...
