interspecific hybridization occurs among cucurbia species it is commonly used for grafting, yield increasing and production of pest resistant rootstocks. in the present research probability of interspecies hybrid generation among seven lines of cucurbita pepo (p1, p4, p5, p6, p10, p22, p25) and six lines of cucurbita moschata (mo3, mo5, mo6, mo9, mo11, mo12) were investigated. after crossing of...

avo as a known methodology is used to identify fluid type and reservoir lithology in subsurface exploration. method discussed in this paper, consists of three stages, including: direct modeling, inverse modeling and cross plot interpretation. by direct modeling we can clarify lithology or fluid dependent attributes. analysis performed using both p-p and p-sv attributes. inverse modeling deals w...

This paper proposes an explanation of the backward-bending labor supply curve that is not based on the premise that the income effect dominates the substitution effect. Unlike the classical labor supply theory that treats working hours and work effort as being synonymous, this paper treats them as distinct variables in an efficiency wage model. A wage rate increase is shown to give rise to two ...

The globalization of production and service enterprises increased the complexity of supply chain systems and processes. The complexity of supply problems leaded to the development of new shipment strategies. The optimal design of supply chain is an important success factor of the economical operation of enterprises. Within the frame of this paper the author compare the costs of the direct shipm...
