Abstract How can we engage the secular in ways that encourage empirical investigations of its specific and embodied expressions? Locating particular places situations invites scholar to recognize it, say “there it is.” However, seems difficult pin down precisely: quickly expands into everything is not considered religion a given context, distinctively evaporate nothing. This article explores sl...

New observations in favour of a significant role of secular evolution are reviewed: central star formation boosted in pseudo-bulge barred galaxies, relations between bulge and disk, evidence for rejuvenated bulges. Numerical simulations have shown that secular evolution can occur through a cycle of bar formation and destruction, in which the gas plays a major role. Since bars are weakened or de...

Just like members of any other profession, not all translators are the same in terms of their ideas, ideals, and code of conduct. Among the modern Iranian translators, a limited, yet influential and professionally well-known, group of them who were among the political activists during Reza Shah Pahlavi (1926-1941) and Mohammad Reza Shah Pahlavi (1941-1979) reigns had to spend so many years in p...

The Korteweg-de Vries (KdV) equation is first derived from a general system of partial differential equations. An analysis of the linearized KdV equation satisfied by the higher order amplitudes shows that the secular-producing terms in this equation are the derivatives of the conserved densities of KdV. Using the multi-time formalism, we prove that the propagation on very long distances is gov...
