COSMO-based process simulations with Aspen Plus/Aspen HYSYS are used, for the first time, to a priori estimate the thermodynamic performance of ammonia absorption refrigeration cycles using ionic liquids as absorbents. This allows not only broadening the criteria set used to select/design ionic...

Whilst their products are substituable for the consumer, there exist technological asymmetries across the unionized sectors of an economy. There are high-tech as well as low-tech sectors. We show, that, due to those asymmetries in productivity, inter-sectoral minimum wage agreements may...
