We treat the non-equilibrium evolution of an open one-particle statistical system, subject to a potential and to an external “heat bath” (hb) with negligible dissipation. For the classical equilibrium Boltzmann distribution, Wc,eq, a non-equilibrium three-term hierarchy for moments fulfills Hermiticity, which allows one to justify an approximate long-time thermalization. That gives partial dyna...
one very decisive factor in students’ academic destiny is the result they get at final term examinations. because of its importance, both students and teachers are curiously anxious about them. as normally it is the case, these final term tests are prepared hurriedly in short time by teachers which result in students’ dissatisfaction, complaining on how the test was different from their expecta...
1 Phonons in a crystal Consider a crystal at very low temperature and expand the potential energy function around the equilibrium positions of the nuclei. The first term of the expansion is simply the energy of the system calculated with the ions in their equilibrium positions, Eperf . If the crystal is near its minimum energy configuration the linear term of the expansion is zero, and the firs...
Introduction: One of the main challenges in the field of health economics is detecting the factors affecting on health costs. One of the these factors is air pollution, which has been ignored in most of empirical studies; while air pollution is one of the environmental problems which in recent years has become a serious threat to human health. Therefore, the aim of this study was to evaluate th...
