Abstract Textiles are valuable cultural heritage items that susceptible to several degradation processes due their sensitive nature, such as the case of ancient ma colored-paintings. Therefore, it is important take measures protect precious artifacts. Generally, ″ma″ includes ramie, hemp, flax, oil kenaf, jute, and so on. In this paper, an examination analysis a painted textile were first step ...

improvements in the properties of ordinary sidewall compound (nr/br) with the addition of epdm by reactive processing method were evaluated. the results show that ozone resistance of these sidewalls was improved with increased addition of epdm. also the tensile strength and elongation-at-break were increased in comparison with nrbrepdm compounds that were made by non-reactive processing. sem ph...

Many thixo-viscoelastic materials have been reported to undergo enhancement in elastic modulus with time and decrease the same under application of deformation field. Incorporation this feature a viscoelastic structural kinetic model has an apparent possibility violating second law thermodynamics. Furthermore, related experimental observation, stress non-monotonic change as function constant st...
