Summary In this article, using the Mizar system [2], [3], we deal with Riemann’s improper integral on infinite interval [1]. As [4], referred to [6], which discusses integrals of finite values.

Journal of Refractive Surgery Volume 17 May/June 2001 ABSTRACT PURPOSE: To review the etiology, prevention, and management of laser in situ keratomileusis (LASIK) complications. METHODS: Review of literature and the experience of the authors. RESULTS: Careful preoperative screening is critical to prevention of many potential complications of LASIK. Flap complications that occur during surgery a...

Background and Aim: Generally, in patients with cervical cancer, careful preliminary evaluation is necessary for avoiding improper surgical procedures and making effective clinical decisions for treatment. The aim of this study was to determine surgeons’ errors, which necessitate a combination of surgery and radiotherapy for cervical cancer patients.    Methods: In this retrospective study, med...

In this paper, we study a colouring problem motivated by a practical frequency assignment problem and up to our best knowledge new. In wireless networks, a node interferes with the other nodes the level of interference depending on numerous parameters: distance between the nodes, geographical topography, obstacles, etc. We model this with a weighted graph G where the weights on the edges repres...

INTRODUCTION Adequate closure of the surgical wound is one of the most important aspects of surgery; improper suturing techniques or improper suturing materials sometimes compromise the success of surgery. Many synthetic materials have replaced the natural materials, which were once used for suturing in the ancient era, and Murva is one of them. There are references of Murva (Sansevieria roxbur...

We study the weighted improper coloring problem, a generalization of defective coloring. We present some hardness results and in particular we show that weighted improper coloring is not fixed-parameter tractable when parameterized by pathwidth. We generalize bounds for defective coloring to weighted improper coloring and give a bound for weighted improper coloring in terms of the sum of edge w...
