Hieroglyphs dominated the landscape of the Egyptian civilisation. These elaborate symbols were ideal for inscriptions on the walls of majestic temples and monuments, and indeed the Greek word hieroglyphica means 'sacred carvings', but they were too fussy for day-to-day scribbling, so other scripts were evolved in Egypt in parallel. These were the 'hieratic' and 'demotic' scripts, which can crud...

Mathematical models for the description, in a quantitative way, of the damages induced on the monuments by the action of specific pollutants are often systems of nonlinear, possibly degenerate, parabolic equations. Although some the asymptotic properties of the solutions are known, for a short window of time, one needs a numerical approximation scheme in order to have a quantitative forecast at...

Twenty samples were taken from the inner or outer surfaces of stone monuments of six historic Scottish buildings and ruins. Biofilms developing on mineral substrates were analysed by in situ scanning electron microscopy and cultivation. Various methods were used to characterize the isolates including automated ribotyping, RAPD and sequencing of the 16S rRNA gene for bacteria, and stereomicrosco...

Delhi is one of the ancient historical and greatest cultural cities of the World. Delhi’s two monuments the Qutb Minar and Humayun’s Tomb have been declared the World Cultural Heritage sites. Delhi was built and rebuilt seven times on different sites through out the history within a triangular area of about 142.20 sq. kms. lying between the last ridge of the Aravalli Range and the River Yamuna....

A. We introduce some free boundary problems which describe the evolution of calcium carbonate stones under the attack of atmospheric SO2, taking into account both swelling of the external gypsum layer and the influence of humidity. Different behaviors are described according to the relative humidity of the environment, and in all cases reliable explicit quasi steady approximations are in...
