In a recent paper [H.-E. Hwang, P. Han, Opt. Commun. 282 (2009) 351] a speckle based metrology system is proposed which it is claimed provides significant advantages over existing systems. In this paper, we show that the discussion presented in [H.-E. Hwang, P. Han, Opt. Commun. 282 (2009) 351] is deficient, and that several of the statements made are incorrect and/or misleading. 2009 Elsevier ...

We propose an aqueous rechargeable Zn-Cu Daniell-type battery. In this system, Li(+) prefers to conduct currents rather than react with the electrodes, while the Zn-Cu electrode couples engage in their electrochemical reactions free from conducting currents. Here Li(+) performs like a messenger and thus could be called the electrochemical messenger.

We discuss the structure of the effective Lagrangian for the (2,2) ZN orbifolds and the corresponding Calabi-Yau manifolds which are obtained by “blowing-up” the orbifold singularities. The method to “blow-up” such singularities is reviewed.’ Results are exact at the string tree-level. In particular the question of generating an intermediate scale MI in such models is addressed. It is shown tha...
