Enhanced oil recovery using nitrogen injection is a commonly applied method for pressure maintenance in conventional reservoirs. Numerical simulations can be practiced for the prediction of a reservoir performance in the course of injection process; however, a detailed simulation might take up enormous computer processing time. In such cases, a simple statistical model may be a good approach to...

In this paper we propose a new way of considering reasoning about action and change Rather than placing a preferential structure onto the models of logical theories we place such a structure directly on the semantics of the actions involved In this way we obtain a preferential semantics of actions by means of which we can not only deal with several of the traditional problems in this area such ...

Plant growth promoting rhizobacteria (PGPR) are known to influence plant growth by various director indirect mechanisms. Thirty–two strains were isolated from 15 soils sampled in central Iran, byusing and comparing three different methods. The screening of soil samples by means of soil paste–plate method combined with isolation on mannitol agar proved to be the best strategy in terms ofreliabil...
