The environmental benefits from road pricing

In this paper the environmental benefits of optimal tolls in eight English towns are estimated. Tolls are simulated using the SATURN model (Simulation and Assignment of Traffic to Urban Road Networks) with associated software to simulate the changes in traffic patterns resulting from cordon tolls. With these results the optimal tolls are computed together with the resulting levels and speeds of traffic in each of our study towns. Changes in vehicle emissions are estimated and reduction in health and global warming costs computed. One of the main results is that any toll designed to reduce traffic congestion would yield positive environmental benefits

Utilisation de mélanges non-azéotropiques dans les cycles thermodynamiques à compression

L'utilisation de mélanges non-azéotropiques comme fluides frigorigènes présente différents avantages en ce qui concerne le fonctionnement des installations de réfrigération / conditionnement / chauffage mettant en oeuvre des cycles thermodynamiques à compression avec changement de phase. En outre, de tels mélanges représentent une alternative intéressante aux corps purs actuellement recherchés pour résoudre les problèmes d'environnement liés à la destruction de la couche d'ozone. Cet article analyse les connaissances acquises concernant la mise en oeuvre d'une telle solution

Novel Capture Processes

Six widely differing, novel capture processes, currently under development in Europe are described. These processes cover the range of postcombustion, precombustion and denitrogenation and show favourable possibilities for integration with power plants. They can be regarded as potential break-throughs in technical performance and/or costs
