Henn （Pgt） with broad virulence to wheat. It is the first known Pgt race possessing virulence to Sr31, a stem rust resistance （Sr） gene deployed in wheat varieties world- wide （Singh et al., 2011 ）. Since the first detection of TFKSK in 1998, a total of 13 Ug99 variants have been identified in several African countries.展开更多

Very high speed performance (above GHz) are not expected at all in conventional electronic mechanism. To achieve high speed performance we may think on the introduction of optics instead of electronics for information, processing and computing. Non-linear optical material is a successful candidate in this regard to play a major role in the optically controlled switching systems and therefore in all-optical parallel computation these materials can show a very good potential aspect. In this paper, we have proposed a new method of an optical half adder as well as full adder circuit for binary addition using non-linear and linear optical materials.展开更多
