We investigate the evolution of metal deficient stars, presentingH-burning isochrones covering cluster ages from800 Myr to 7 Gyr. Evolutionary evidences for selection effects in the metallicity distribution of very metal poor H-burning red giants are reported. The evolution of stars during central and shell He burning is further investigated, discussing the occurrence of He burning pulsators as...

Preparation of micron and nano sized ammonium perchlorate (AP) particles in propellant formulation is required for access high burning rate propellants. The decomposition and burning rate of AP particles are mainly affected by decreasing the particle size, which can decrease the decomposition temperature, and increase burning rate.  AP particles at the micro and nano-scales, have a great influe...
