Matière Condensée : Chimie Et Organisation

The stepwise solvation-equilibrium model of Stokes and Robinson isused for a description of departures from ideality in ionic solutions. It is shown howto construct a thermodynamically consistent model including solvation effects. Sim-ple expressions are derived for the mean ion solvation number. The model is appliedto strong electrolyte solutions (pure water+salt and mixed aque...

Technologie et organisation : le hasard et la nécessité

Evolution of ICT in organizations are following two contradictory trends. One the one hand, definition and concepts defining these technologies are loosing specificity, on the other hand, these technologies take a growing place in organizational life. Characterization of ICT is particularly difficult as ICT are especially flexible and can be substituted easily to one another. The reasons are nu...

Matì Ere Condensée, Chimie Et Organisation

The effect of temperature in the range of 0–150 8C was studied for homoionic montmorillonite clays with Na and Csqq compensating ions in low hydration states. Both static and dynamic information concerning the interlayer ions and water moleculeswas obtained by Monte Carlo and molecular dynamics. Principal structural changes were limited to the water phase, markeddifference was o...

NSF Long Term Ecological Research Sites - Praxis et Theoria

Information managers at each of the 26 sites in the Long Term Ecological Research (LTER) Network face many challenges managing structurally and thematically diverse ecological data sets collected by LTER scientists. Since the LTER’s inception in 1980, LTER information managers have partnered with computer scientists to seek innovative information management solutions. This panel of three comput...
