This study deals with simulate assumed designs for ruby laser resonator from calculate radius of Specialty Pipes laser beam at the beam waist, diameter of laser beam and curvature radius of laser beam at distance (z).The results found the best design of ruby laser resonator has very small divergence angle and high degree of directionality.Its found

Screen for genetic modifiers of stbm reveals that photoreceptor fate and rotation can be genetically uncoupled in the Drosophila eye.

Polarity of the Drosophila compound eye arises primarily as a consequence of two events that are tightly linked in time and space: fate specification of two photoreceptor cells, R3 and R4, and the subsequent directional movement of the unit eyes of the compound eye, or ommatidia.While it is thought that these fates dictate Motorcycle the direction
