Fluid Transport in High-Volume Fly Ash Mixtures with and without Internal Curing

October 7, 2013
Author(s)
Igor de la Varga, Robert Spragg, Carmelo di Bella, Javier Castro, Dale P. Bentz, Jason Weiss
The transport of fluid and ions in concrete mixtures is central to many aspects of concrete deterioration. As a result, transport properties are frequently measured as an indication of the durability that a concrete mixture may be expected to have. This

Myocardial Calcification in Captive Grouper Epinephelus Aeneus

June 1, 2009
Author(s)
Naomi Eidelman, A Colorni, Jirun Sun, M.C. Fishbein, A Diamant
A case of myocardial calcification is described in the Mediterranean white grouper, Epinephelus aeneus, cultured as broodstock in Eilat (Israel, Red Sea). Large calcified nodules and scar tissue were observed in the ventricular tissues. The chemical

Glass Pocket Evolution in Vitreous Bonded Sapphire

October 16, 2008
Author(s)
Jong S. Lee, M K. Kang, Sheldon M. Wiederhorn, B Hockey, J Blendell
This paper discusses the evolution of glass filled pockets formed by the growth of sapphire through polycrystalline aluminum oxide bonded by anorthite glass. During growth, excess glass is entrapped within the sapphire as channels, which, upon annealing

Particle Growth in Silane RF Discharges

October 16, 2008
Author(s)
Alan Gallagher
Calculations and measurements of particle growth in silane RF capacitively coupled discharges are reported. The measurements of particle diameters of 8 nm to 50 nm. This particle growth is typically 50 times as fast as film growth, and measured density

Ca 4 Nb 2 0 9 -CaTi0 3 : Phase Equilibria and Microstructures

August 1, 2001
Author(s)
Leonid A. Bendersky, Igor Levin, Robert S. Roth, Alexander J. Shapiro
Ca 4TiO 3-Ca 4Nb 2O 9 is a quasi-binary section, and all the phases participating in equilibrium are solid solutions of the binary end-members. The phases are perovskite-based ABO3-type, with a common stoichiometry Ca[Ca (1-x)/(3-2x)Nb (2-2x)/ (3-2x)Ti x/

Collisional Decomposition of SF 6

September 1, 2000
Author(s)
R. Champion, I. V. Dyakov, Yicheng Wang
Insulating gas mixtures containing SF 6 have been promoted to serve as replacements for pure SF 6 in order to reduce SF 6 atmospheric emission. It has been argued that some synergism may be achieved by choosing proper buffer gases in mixtures with SF 6
