Prices, property and markets in water allocation
(ECLAC, 1998-02)
Abstract
This paper examines the means to incorporate the use of market signals through prices into water resources management with the objective of improving efficiency in the allocation of water. It reviews a vast body ...
Correlation for the variations with temperature of solute solubilities in high temperature water
(ELSEVIER, 2011)
Methods for estimating solute solubilities in high temperature water both below and above its boiling point (under pressure) are needed for applications of this medium in processing applications such as sub-critical water ...
