Steady hydromagnetic Couette flow of class-II of a viscous, incompressible and electrically conducting fluid through a porous medium in a rotating system taking Hall current into account is investigated. Heat transfer characteristics of the fluid flow are considered taking viscous and Joule dissipations into account. It is noticed that there exists flow separation at the moving plate in the sec...

While students are required by government mandated syllabi to make a successful translation between different semiotic resources, there still remains a lack of research on the grammars and functionality of the specialized modalities to develop explicit instructions to improve literac...
