Of the several of minerals used in Ayurveda practice as Vaikranta, the most commonly used were procured from reputed Ayurveda pharmacies all over India and those responding to physical characteristics of Vaikranta as mentioned in Ayurveda texts were subjected to physical, chemical and spectral analysis. X-ray diffraction study of Schorlite was undertaken to conform mineral constitutions of the ...

Naturally, deformed rocks commonly contain crack arrays (joints) forming patterns with systematic relationships to the large-scale deformation. Kinematically, joints can be mode-1, -2 or -3 or combinations of these, but there is no overarching theory for the development of the patterns. We develop a model motivated by dislocation pattern formation in metals. The problem is formulated in one dim...

We extend the mechanism for noise-induced phase transitions proposed by Ibañes et al. [Phys. Rev. Lett. 87, 020601 (2001)] to pattern formation phenomena. In contrast with known mechanisms for pure noise-induced pattern formation, this mechanism is not driven by a short-time instability amplified by collective effects. The phenomenon is analyzed by means of a modulated mean field approximation ...
