as observed in some oil and gas countries, upstream service contracts, for instance buy-back contract in iran, would provide an appropriate environment for the development of oil and gas fields. however, certain cases, such as common structures and reservoirs, deep sea oil fields or second and third generations of an oil field may require more attractive contractual mechanisms in the eyes of io...

In the first part of this paper, some theorems are given for a Riemannian manifold with semi-symmetric metric connection. In the second part of it, some special vector fields, for example, torse-forming vector fields, recurrent vector fields and concurrent vector fields are examined in this manifold. We obtain some properties of this manifold having the vectors mentioned above.

unlike the islamic code (approved 1370/1991) in which no suitable attention had been paid to the rule of interference of retaliation, the islamic punishment code (approved 1392/2013) has discussed this rule as well as the rule of interference of blood-moneys in details and in which some innovations may be seen. in spite of increase in the number of articles concerning this rule, some innovation...

The relative growth of field and metric perturbations during preheating is sensitive to initial conditions set in the preceding inflationary phase. Recent work suggests this may protect super-Hubble metric perturbations from resonant amplification during preheating. We show that this possibility is fragile and sensitive to the specific form of the interactions between the inflaton and other fie...
