A natural convection model for mass transfer and the dissolution rate equation derived by considering intermetallic compound layer formation were used to interpret the experimental dissolution data. A larger dissolution at the upper part of specimen causing natural convection and an intermetallic layer ...

1. For glassy basalt the rate equation isJSi=(5.00×102)e(−39700R) Rate equations The rate equations reported in this paper apply to a composition representative of Icelandic basalts containing ∼48% SiO2. Wolff-Boenisch et al. (2004a) showed that volcanic glass dissolution rates change ...
Empirical rate equations such as R=k(1−c/ceq)n in the dissolution of minerals are common in nature, e.g. limestone. The quantity c is the concentration of a major ion contained in the mineral, and ceq its concentration at equilibrium. If experimental data obey such a rate equation, ...

Theee amplification takes place when the flow terminates on aline of fixed points (or afixed line),whereas symmetry breaking corresponds to the dissolution of the fixed line accompanied by the appearanceof fixed points. The relevance of the Soai reaction to the homochirality in life is also ...
sometimes accompany dissolution phenomena due to prolonged time spent in the solution, the sensitivity to the deformation rate results from the effects of plasticity and plasticity-liquid metal interaction. Deformation rate effects are sometimes coupled with the effects of the bath's chemistry (Figure ...
aSecond, much effort is often expended in deriving the “correct” rate equation and associated parameters for a given system. The practice of reducing observations of a complex dissolution mechanism into an overall rate law runs the risk of obscuring the meaning of variations in rate. 其次,努力...
Examples of Overhead Rates The equation for the overhead rate is overhead (or indirect) costs divided by direct costs or whatever you're measuring. Direct costs typically are direct labor, direct machine costs, or direct material costs—all expressed in dollar amounts. Each one of these is ...
