Molten salts consisting of 60% sodium nitrate and 40% potassium nitrate have been used successfully as a thermal energy collection and storage fluid in different solar thermal plants. However, the relatively high melting point of this mixture (221°C) represents an important risk of local...

A novel modelling framework for the simulation of the diffusive mass transport limitations occurring at GDL local scale of PEFCs is presented, in particular in relation with the distribution of liquid water in the porous media. The distinctive characteristic of this framework is the fact that...

Earth, wood and others traditional materials are still used in house constructions in many regions of the world, especially in the Andes. San Pedro de Atacama, for example, is a small town where earth blocks (adobes) and rammed earth (tapial) are important ways to construct, an art passed on...

This paper presents a dual economy model of the fix-price/flex-price kind that explicitly allows for the existence of a government budget constraint in a fully open economy. Both the external and fiscal closures resemble very much the contemporary experience of several Latin American countries,...

This paper develops a general extended version of the balance-of-payments -constrained growth model that takes into account three often ignored aspects of contemporary growth in open economiesânamely, trade imbalances and the importance of net financial flows in the long run, relative price...
