S'explica el que preveu a la Llei 30/2007 de Contractes del Sector Públic en matèria de control del serveis externalitzats. La poca exigència de la llei fa concloure que a Espanya es produeix el fenomen conegut com captura o segrest del regulador.

A new conceptualization of the investments is defended in accordance with the nature of the uncertainty. The results of this conceptualization offer a theory of the investment compatible with the concept of intrinsec value that is been able expressed in mathematical model. This model is an alternative to the named 'pricing models'.

L'avaluació econòmica en els contractes públics. En aquest document es descriu i analitza allò que preveu la Llei 30/2007 de contractes del sector públic en matèria de avaluació econòmica dels contractes arribant a la conclusió de que l'exigència de la Llei és molt pobre. Es proposa també com enfocar una metodologia sobre avaluació econòmica dels contractes públics.

Self- and cross-velocity correlation functions and related transport coefficients of molten salts are studied by molecular-dynamics simulation. Six representative systems are considered, i.e., NaCl and KCl alkali halides, CuCl and CuBr noble-metal halides, and SrCl2 and ZnCl2 divalent metal-ion halides. Computer simulation results are compared with experimental self-diffusion coefficients and electrical conductivities. Special attention is paid to dynamic cross correlations and their dependence on the Coulomb interactions as well as on the size and mass differences between anions and cations.
