Position vectors of a spacelike W-curve in minkowski space E-1(3)
(Korean Mathematical Soc, 2007)
In this paper, we study the position vectors of a spacelike W-curve (or a helix), i.e., curve with constant curvatures, with spacelike, timelike and null principal normal in the Minkowski 3-space E-1(3). We give some ...

On approximation properties of a family of linear operators at critical value of parameter
(Academic Press Inc Elsevier Science, 2006)
We introduce the family of linear operators [GRAPHICS] associated to a certain "admissible bunch" of operators S-t, t > 0, acting on L-p (R-n, dm, and investigate the approximation properties of this family as alpha -> ...
Testicular nitric oxide and thiobarbituric acid reactive substances levels in obstructive azoospermia: A possible role in pathophysiology of infertility
