the key to successful long-term peritoneal dialysis (pd) is permanent and safe access to peritoneal cavity. the two most commonly used tenckoff catheters for pd are the straight and coiled catheters. the present study was undertaken to assess the catheter survival, catheter associated infections, and all cause mortality and to compare the straight with coiled catheters in pd. during april 1997-...

The straight skeleton of a simple polygon is defined as the trace of the vertices when the initial polygon is shrunken in self-parallel manner [2]. In this paper, we propose a simple algorithm for drawing the straight skeleton of a monotone polygon. The time and space complexities of our algorithm are O(nlogn) and O(n) respectively.

This study was conducted to determine the accuracy of bracket placement with the direct bonded technique. Ten orthodontic faculty members bonded a preadjusted orthodontic appliance on models of five cases of malocclusion in a simulated clinical situation (mannequin). A total of 50 sets of models served as the population of the study. Photographs of the models were measured to determine vertical...

in this study, as for the re-casting, surface alloying and re-solidification layer of this alloys at the work piece level machining with wire electro discharge machining (wedm), changes of surface micro hardness with changes of operational parameters has been studied. therefore, study shows using surface alloying phenomena with the diffusion of wire material into the machined surface and select...

Nowadays, advanced turning processes are extensively being adopted to perform different types of operations such as straight turning, taper on Hastelloy, Nimonic, and Inconel, stainless steel, tool steel fabricate better quality cylindrical rotating parts miniature-bars, miniature-pins, miniature-electrodes, miniature-tools. This paper presents a review the previous research conducted miniature...
