Nowadays, green chemistry and its advantages are generating interest of researchers toward ecofriendly biosynthesis of the metallic nanoparticles. In this research, a rapid, simple and green method was developed for the synthesis of silver nanoparticles using aqueous extract of Prangos ferulaceae leaves. The synthesized silver nanoparticles were characterized by UV-Vis spectroscopy, sc...

Based on the generating functional method with an external source function, a useful constraint on the source function is proposed for analyzing the oneand two-loop world-line Green functions. The constraint plays the same role as the momentum conservation law of a certain nontrivial form, and transforms ambiguous Green functions into the uniquely defined Green functions. We also argue reparame...

Continuing recent architectural trends that rely on branch predictions, value predictions, speculative execution, and reuse of results from instruction execution, we investigate the reuse of results from previous function invocations. In this paper we show that for integer benchmarks, it is possible to eliminate some function invocations since the same function is executed repeatedly with the s...

Background: Developing effective methods for the synthesis of bio-compatible and non-toxic nanoparticles is the main goal of nanotechnology. In the most chemical methods, a chemical reducing agent is used to reduce metal ions. But, in chemical methods, the stability of nanoparticles is controversial and synthesis in large sizes is much more difficult. Moreover, there is an incr...
