The aim of this paper is to complete the concept structure, in structuration theory, with worldview. Giddens' theory emphasizes structure as a result well medium for regularization social practice. It cognition but ignores society. As result, does not explain how practices that produce virtual structures can exist and be practiced continuously society, before are formed agents’ cognition? There...

The study of inter-human communication requires a more complex framework than Shannon’s (1948) mathematical theory of communication because “information” is defined in the latter case as meaningless uncertainty. Assuming that meaning cannot be communicated, we extend Shannon’s theory by defining mutual redundancy as a positional counterpart of the relational communication of information. Mutual...

The technique of large-eddy simulation (LES) has been applied to the study of pulsatile flow through a modeled arterial stenosis. A simple stenosis model has been used that consists of a one-sided 50 percent semicircular constriction in a planar channel. The inlet volume flux is varied sinusoidally in time in a manner similar to the laminar flow simulations of Tutty (1992). LES is used to compu...
