despite the consensus of jurists (fokaha) in safe custody of property (haraz) as one of the punishable conditions when the theft happens, some jurists made an exception in bird case. it means that stealing the bird would not subject to punishment namely cut off the thief's hand, even if the bird was in safe custody.  many of  fokaha, however,  believe that if the bird is in safe custody, t...

The aim of this work is a construction of a dual mixed finite element method for a quasi–Newtonian flow obeying the Carreau or power law. This method is based on the introduction of the stress tensor as a new variable and the reformulation of the governing equations as a twofold saddle point problem. The derived formulation possesses local (i.e. at element level) conservation properties (conser...

Abstract A comprehensive study of the rheological characterization aqueous solutions polyethylene oxide (PEO) with molecular mass 4 × 106, 5 and 8 106 g/mol, respectively, named (4 miDA), (5 (8 miDA) was conducted. large batch samples miDA PEO concentrations varying from 0.1% to 3%, representing range dilute very high viscous hydrated gels, were tested. Steady-state shear flow oscillatory measu...

Abstract Carreau fluids are a source of research from both theoretical and applied approaches. They have been considered to model different non-newtonian phenomena such as blood flow, plasma viscoeslastic materials. The purpose this study is develop the global regularity criteria for fluid in two dimensions flowing strip. Firstly, shown initial set $$\left( u_{10},u_{20}\right) \in H^{1}\left( ...
