for a given riemannian manifold (m,g),it is an interesting question to study the existence of a conformal diffemorphism (also called as a conformal transformation) f : m ! m such that the metric g? = fg has one of the following properties: (i)(m; g?) has constant scalar curvature. (ii)(m; g?) is an einstein manifold.

Introduction & Objective: Knowledge transfer and in fact, the bridging of theory and practice is one of the main concerns of all academic disciplines. Getting prominent professional status is the thing that can be achieved by knowledge-based function, and of which would be called as successful discipline that it be able to transfer its theoretical paradigmatic claims into practice. Accordingly,...

abstract sensitive and precise voltammetric methods for the determination of trace amounts of furaldehydes, mainly as furfural (f) and 5-hydroxymethyl-2-furaldehyde (hmf), in waste waters and other matrices is described. determination of total furaldehyde at < ?g g-1 levels in alkaline buffered aqueous media was individually investigated. by the use of ordinary swv and adsorptive square wave ...

  There is no convergence in the results of the credit relationship between the financial contracting parties (banks and customers) due to the different importance of the contract variables. Therefore, while examining the impact of the empirical relationship between the variables commercial profit-loss sharing contracts, the dual role of the collateral variable (screening and motivation) is in...
