It has been recognized since at least as early as the mid-1500s that inhaled minerals (i.e., inorganic particles) can pose a risk. Extensive research has focused on the biological mechanisms responsible for asbestos- and silica-induced diseases, but much less attention has been paid to the mineralogical properties and geochemical mechanisms that might(More)
gamma-Aminobutyric acid (GABA), an amino acid, has been found in every class of living organisms. In higher organisms, GABA is a neurotransmitter and binds with high affinity and specificity to GABA receptors on neurons in a sodium-independent reaction that is saturable. The role of GABA in organisms lacking nervous tissue is not known. This report(More)
Reduced-order modeling is a promising approach, as many phenomena can be described by a few dominant modes/mechanisms. The goal of this paper is to assess the utility of Reduced-Order Models (ROMs) developed from three-dimensional physics-based models for predicting transient thermal power output for an enhanced geothermal reservoir while explicitly(More)
Crystal defects and chemical reactions occurring at scales beyond the resolution of light microscopes have major effects on the chemical and physical properties of rocks and minerals. High-resolution imaging, diffraction, and chemical analysis in the transmission electron microscope have become important methods for exploring mineral defect structures and(More)
