purpose: to report the outcomes of conjunctival-limbal autograft (clau) in patients with unilateral total limbal stem cell deficiency (lscd) emphasizing surgical problems, complications, and their management. methods: in this prospective interventional case series, clau combined with amniotic membrane transplantation as a graft was performed on 26 patients with unilateral total lscd due to chem...

the coordinate transformation allows the exact calculation of some electrode configurations. in this paper the prolate spherical coordination transformation is used to calculate the field of a hyperboloiderod against plan electrode. the exact field is caculated using two new parameters: 1) electrodes spacing and 2) the radius of curvature of the tip of the rod electrode. the partial discharge i...

Hadamard (or complete $CAT(0)$) spaces are complete, non-positive curvature, metric spaces. Here, we prove a nonlinear ergodic theorem for continuous non-expansive semigroup in these spaces as well as a strong convergence theorem for the commutative case. Our results extend the standard non-linear ergodic theorems for non-expansive maps on real Hilbert spaces, to non-expansive maps on Ha...

introduction: providing the material for penile reconstruction after release of chordee associated with hypospadias is challenging. we have used the preputial vascularized island flap for this purpose. we report the results of this prospective study. materials and methods: one hundred and twelve boys ranging from 13 months to 12 years of age were enrolled in this study. the location of meatus r...

in order to present a quantitative indicator for the onset of instability, in this paper, the critical points of a stratified gravitational flow on a slope are found and analyzed. these points are obtained by means of the solution of the two-dimensional navier-stokes equations via the standard arakawa-c finite-difference method. results show that in the marginal richardson numbers, the critical...
