In this article, the effect of electromagnetic force with thermal radiation on Williamson nanofluid a stretching surface through porous medium was studied considering both heat generation/absorption and Joule heating. On other hand, Brownian motion thermophoresis coefficients considered. The system nonlinear partial differential equations governing study fluid flow has transformed into ordinary...

Intransitivity and introspection. One central and debated aspect of the notion of inexact knowledge concerns the non-transitivity of the relation of indiscriminability and how it should be represented. On the epistemic account of vagueness put forward by Williamson, the intransitivity of the relation of indiscriminability is presented as the main source for vagueness ([5]: 237). In [4] and in t...
