Global Existence of Solutions to a Nonlinear Model of Sulphation Phenomena in Calcium Carbonate Stones
We prove global existence and uniqueness of smooth solutions to a nonlinear system of parabolic equations, which arises to describe the evolution of the chemical aggression due to the action of sulphur dioxide on calcium carbonate stones. This system is not uniformly parabolic and only some energy estimates are available. Nevertheless, global (in time) results are proven using a weak continuati...
متن کاملDecay factors and patterns of stones in open-air historical sites built of carbonate sedimentary stones
The number of historical open-air sites built of stone are relatively limited in comparison to the other historical artificial in Iran, but these sites include great significance in terms of value, historic and their knowledge of past. Since these stone poen-air sites are generally about two thousand years old, they have been exposed to decay factors for a long time. Many information and data o...
