Let X be a 3-dimensional complex manifold(variety) , C ⊆ X an exceptional curve. We prove that 1 1 C ⊆ X is also an exceptional curve,where 1 C is a negative section corresponding to the exact sequence of And C I is an C O -ideal.

In this work, we have studied the issue of approximation of functions from Morrey
space ; by rational functions on a large group of curves,
which called Dini-smooth curves. Moreover, approximation of functions from Morrey
Smirnov space defined on a finite domain with a boundary belonging to Dini- smooth
curves by polynomials is obtained.
We study in this research approximation of complex functions from Orlicz space on a subclass of Carlson curves, which called Dini smooth curves to rational functions by using polynomials related with Dzjadyk sums which obtained from Faber polynomials. We depend on some concepts of complex analysis such as formulas of Sokhotski to reach the desired goal
in this search this water is treated with some materials to the rock become much lover to

water effect on relative permeability curves and connected quantity
water before an

The purpose of this reseated is to estimate cerebral blood flow in the cerebral
microvasculature beds by measuring the change of the intensity gray scale levels in dynamic
angiographic images which have been acquired by Digital Subtraction Angiography (DSA).
In this research, we have studied the issue of approximation of complex functions from weighted Lebesgue space ; and (Mukenhoupt weight) to rational functions by using p- Faber polynomials on large group of curves, which called Carlson curves. This
is also considered as a follow-up to the work done by researchers: Israfilov and Testici in 2014 , where they studied approximation of functions from weighted Smirnov space on domains with a Carlson curve boundary.
