Regulating Iranian Card payments System as a two sided market
This paper examines the necessity of regulating the Iranian card payments system (SHAPARAK) based on the theory of two-sided markets. The expansion of the payment card system in recent years has arisen some questions regarding the role of all kinds of costs and expenses such as interchange fees, cardholder fees, merchant fees, and network externality in balancing the market. Since there is only...
متن کاملSkyrmion-skyrmion Scattering
We study the scattering of Skyrmions at low energy and large separation using the method proposed by Manton of truncation to a finite number of degree freedom. We calculate the induced metric on the manifold of the union of gradient flow curves, which for large separation, to first non-trivial order is parametrised by the variables of the product ansatz.
متن کاملsynthesis of platinum nanostructures in two phase system
چکیده پلاتین، فلزی نجیب، پایدار و گران قیمت با خاصیت کاتالیزوری زیاد است که کاربرد های صنعتی فراوانی دارد. کمپلکس های پلاتین(ii) به عنوان دارو های ضد سرطان شناخته شدند و در شیمی درمانی بیماران سرطانی کاربرد دارند. خاصیت کاتالیزوری و عملکرد گزینشی پلاتین مستقیماً به اندازه و- شکل ماده ی پلاتینی بستگی دارد. بعضی از نانو ذرات فلزی در سطح مشترک مایع- مایع سنتز شده اند، اما نانو ساختار های پلاتین ب...
Evidence that cytochrome b5 and cytochrome b5 reductase can act as sole electron donors to the hepatic cytochrome P450 system.
We previously described the development of genetic models to study the in vivo functions of the hepatic cytochrome P450 (P450) system, through the hepatic deletion of either cytochrome P450 oxidoreductase [POR; HRN (hepatic reductase null) line] or cytochrome b(5) [HBN (hepatic cytochrome b(5) null) line]. However, HRN mice still exhibit low levels of mono-oxygenase activity in spite of the abs...
متن کاملLow energy Skyrmion-Skyrmion scattering.
We study the scattering of two Skyrmions at low energy and large separation. We use the method proposed by Manton for truncating the degrees of freedom of the system from in nite to a manageable nite number. This corresponds to identifying the manifold consisting of the union of the low energy critical points of the potential along with the gradient ow curves joining these together and by posit...
