A Lagrangian analysis explains the numerical results of Valentini and Westman (2005) which demonstrate that an initially arbitrary particle density, stirred by the field of de Broglie velocities associated with a Schrödinger wave function, relaxes to the Born probability density provided both densities are coarse–grained.

We present a substantial upgrade of our previously developed multi-filter rotating shadowband (MFRSR) data analysis algorithm (Alexandrov et al. 2002). For the new version an automated cloud screening procedure (Alexandrov et al. 2004) has been designed and a bimodal aerosol particle size distribution model is used defined by a variable fine mode size and a ratio between the fine and coarse modes.

Kinetics of the chemical leaching of chalcocite from a low-grade copper ore in a ferric sulfate medium was investigated using the constrained least square optimization technique. The experiments were carried out for different particle sizes in both the reactor and column at constant Eh, pH, and temperature. The leaching rate increased with increase in the temperature. About 50% of the Cu recove...
