purpose: to measure corneal power using different methods to assess agreement between these methods among patients who underwent photorefractive keratotomy. methods: in this prospective comparative study, keratometry was measured in 66 eyes of 33 refractive surgery candidates using manual keratometry (kr), conventional topography average central corneal power (accp), galilei total corneal power...

in this paper, the behavior of saving and consumption has been considered in ramsey – cass- koopmans model’s framework. our purpose was investigation of dynamics of these variables and analysis of their response to other parameter and variable variations. so, we made lagrangian function subject to some restrictions and euler equations and other steady state path equations. and then, we have cal...

Hilbert C∗-modules are useful tools in AW ∗-algebra theory, theory of operator algbras, operator K-theory, group representation theory and theory of operator spaces. The theory of Hilbert C∗-modules is very interesting on its own. In this paper we give fundamentals of the theory of Hilbert C∗-modules and examine some ways in which Hilbert C∗-modules differ from Hilbert spaces.
