This article examines how recent changes in the hybrid media environment have led actors to define “how and why” of their practices. We consider discussion on differences similarities surrounding both legacy media, newcomers such as countermedia, be part journalism’s boundary work: ongoing, yet temporally fickle, process marking boundaries between journalism non-journalism. demonstrate counterm...

In this paper, a generalized expression for the flow field in axisymmetric extrusion process is suggested to be valid for any dies and the boundary shapes of the plastic deformation zone. The general power terms are derived and the extrusion force is calculated by applying upper bound technique for a streamlined die shape and exponential functions for shear boundaries. It is shown that assuming...
