X–ray observations indicate that non–gravitational processes play a key role in the thermodynamics of the Intra Cluster Medium (ICM). The effect of non–gravitational processes is imprinted in the ICM as an entropy minimum, whose effects are visible in the Luminosity– Temperature relation and in the Entropy–Temperature relation. However, the X–ray emission alone cannot discriminate between diffe...

Scientists all over the world are in search of new and renewable energy sources. One of the options is to develop energy storage devices, which are as important as developing new sources of energy. Thermal energy storage systems provide the potential to attain energy savings, which in turn reduce the environment impact related to energy use. Infact, these systems provide a valuable solution for...

The use of renewable energy (RE) is considered one the most important topics discussion regarding sustainable consumption and environmental protection nowadays. More than ever, a new crisis forming due to effect political military conflicts that have already been in place for some time. Our research envisages using sample 1126 respondents validation theoretical model highlights complex relation...

We consider a nonlinear system and show the unexpected and surprising result that, even for high dissipation, the mean energy of a particle can attain higher values than when there is no dissipation in the system. We reconsider the time-dependent annular billiard in the presence of inelastic collisions with the boundaries. For some magnitudes of dissipation, we observe the phenomenon of boundar...
