The experimental cystotomy was performed on 24 mongrel dogs, divided in to four groups i.e. group A, B, C and D comprising 6 dogs in each group. In group-A, cystotomy wound was closed in one layer by simple continues suturing pattern, in group-B, closure was made in two layers by simple continues and lembert suturing pattern and in group-C, cystomy incision was closed by one layer simple contin...

Introduction: The most common type of velopharyngeal valve (VPV) closure is a matter of controversy.The aim of this study was to estimate the most common type of VPV closure, including identification of the type and grade of VPV closure among Egyptian children.  Materials and Methods: This study included patients who were candidates for adenotonsillectomy. In these cases, video-nasoendoscopy an...

We present a quantization of a Lie coideal structure for twisted half-loop algebras of finite-dimensional simple complex Lie algebras. We obtain algebra closure relations of twisted Yangians in Drinfeld J presentation for all symmetric pairs of simple Lie algebras and for simple twisted even half-loop Lie algebras. We provide the explicit form of the closure relations for twisted Yangians in Dr...

INTRODUCTION The commonest complication following hypospadias repair is occurrence of urethrocutaneous fistula. The smaller fistulas (<2 mm) are easier to close with a simple closure whereas larger ones (>2 mm) with good vascular surrounding skin require a local skin flap closure for avoiding overlapping suture lines. For the recurrent/larger fistulas with impaired local surrounding skin - inci...

For a mixed integer linear program where all integer variables are bounded, we study a reformulation introduced by Roy that maps general integer variables to a collection of binary variables. We study theoretical properties and empirical strength of rank-2 simple split cuts of the reformulation. We show that for a pure integer problem with two integer variables, these cuts are sufficient to obt...

Semigroups with an additional unary operation called a (right) closure are investigated. These “closure semigroups” may be viewed as (not necessarily regular) generalisations of inverse semigroups, and several powerful structural aspects of inverse semigroup theory are shown to extend naturally to some important classes of closure semigroups. These include representations as partial transformat...

Pilonidal sinus disease (PSD) is a common chronic, benign disease of young adulthood. Pilonidal disease is an infection under the skin in the gluteal cleft. Pilonidal literally means a „„nest of hair”. Known risk factors include family history, local trauma, sedentary occupation, and obesity. Pilonidal sinus disease is a blind track, which extends from the skin of natal cleft up to the presacra...

In this paper, the notion of closure operators of matroids  is generalized to fuzzy setting  which is called $M$-fuzzifying closure operators, and some properties of $M$-fuzzifying closure operators are discussed. The $M$-fuzzifying matroid induced by an $M$-fuzzifying closure operator can induce an $M$-fuzzifying closure operator. Finally, the characterizations of $M$-fuzzifying acyclic matroi...

A new algorithm for path selection in Automatically Switched Optical Networks is presented and demonstrated. This algorithm is based upon Eye Closure Penalty and involves a simple modification of the current OSPF protocol. ASON, path selection, OSPF, Eye Closure Penalty
