Historical Interactions of Dārā Shukūh with Hinduism

This Article, with a descriptive-analytical method and phenomenological approach, tries to explain the motives, solutions, and achievements of Dārā Shukūh (fl. 11th century AH) in Muslim-Hindu relations. It will also describe his ways of interaction and explain some negative reactions against his policies. Dārā Shukūh’s main motives were his special family upbringing, his chivalrous ...

Length scales of interactions in magnetic, dielectric, and mechanical nanocomposites

It is investigated how figures of merits of nanocomposites are affected by structural and interaction length scales, Aside from macroscopic effects without characteristic lengths scales and atomic-scale quantum-mechanical interactions there are nanoscale interactions that reflect a competition between different energy contributions. We consider three systems, namely dielectric media, carbon-bla...

New particle formation from photooxidation of diiodomethane (CH<subscr>2</subscr>I<subscr>2</subscr>)

[1] Photolysis of CH2I2 in the presence of O3 has been proposed as a mechanism leading to intense new particle formation in coastal areas. We report here a comprehensive laboratory chamber study of this system. Rapid homogeneous nucleation was observed over three orders of magnitude in CH2I2 mixing ratio, down to a level of 15 ppt ( 4 10 molec. cm ) comparable to the directly measured total gas...
