We illustrate the matrix representation of the closed range operator that
enables us to determine the polar decomposition with respect to the
orthogonal complemented submodules. This result proves that the reverse
order law for the Moore-Penrose inverse of operators holds. Also, it is
given some new characterizations of the binormal operators via the
generalized Aluthge transformation. New characterizations of the binormal
operators enable us to obtain equivalent conditions when the inner product
of the binormal operator with its generalized Aluthge transformation is
positive in the general setting of adjointable operators on Hilbert
C*-modules.
