BACKGROUND AND OBJECTIVES Trocar-site incisional hernias are the most common complications in laparoscopic surgery. Fascial closure of port sites represents a challenging issue in laparoscopic surgery. METHODS We describe a simple easy technique for fascial closure of port sites using a double-tip needle (Lasheen needle). This study included 100 patients who underwent laparoscopic surgery fro...

Indications for internal closure of the larynx are the same as those set out by Smith, Spalding, Ardran, and Livingstone (1965) for laryngectomy in non-malignant conditions. There should be no prospect of recovery from the pharyngeal palsy which endangers the life of the patient from inhalation pneumonia. The advantage of closure of the larynx over laryngectomy is that it is only a mildly traum...

background: cutaneous malignancies are common in dermatologic practice. due to their relation to sun exposure the characteristics of these malignancies can differ in various geographic locations. this study intends to determine the characteristics of surgically treated cutaneous malignancies and various surgical modalities that have been applied. methods: this was a retrospective study of patie...

using cold working fastener holes is a simple life enhancement procedure that strengthens metallic components by retarding crack growth around a hole. in the present paper, the residual stress field that is induced by the hole expansion process is obtained based on different material models namely elastic perfect plastic, isotropic hardening and kinematic hardening using three-dimensional finit...

Objective: To determine the incidence of surgical site infection in patients after primary closure with perforated or gangrenous and simple appendicitis. Background: Appendectomy is the most commonly performed procedure in surgical emergency departments throughout the world .After appendectomy most surgeons nowadays prefer primary delayed closure in patients having gangrenous or perforated appe...

Genomic sequencing typically generates a large collection of unordered contigs or scaffolds. Contig ordering (also known as gap closure) is a non-trivial algorithmic and experimental problem since even relatively simple-to-assemble bacterial genomes typically result in large set of contigs. Neighboring contigs maybe separated either by gaps in read coverage or by repeats. In the later case we s...

This paper focuses on the basic operations of Chomsky’s languages. The validity and the effectiveness of some closure operations, such as union operator, product operator and Kleene Closure operator, are discussed in detail. The crosstalk problems in Context-Sensitive Languages (CSL) and Phrase Structure Languages (PSL) are analyzed, and a valuable method to solve this problem is presented by s...

The computational formulation of a new nonequilibrium Reynolds stress closure is presented along with preliminary validation results for both homogeneous and inhomogeneous turbulent flow problems of practical engineering importance. The new nonequilibrium closure, which has been rigorously derived elsewhere, replaces the classical Boussinesq hypothesis appearing in many current two-equation tur...
