Abstract Introduction The presence of the appendix within a femoral hernia was first described by René De Garengeot in 1731. Less than 200 cases have been reported literature with an incidence 0.5–5% all hernias. Case Description A 69-year-old woman presented 72-hour history painful right-sided groin swelling. She denied fever or any gastrointestinal symptomatology. Clinical examination reveale...

  Purpose: Mesh technique is the standard for inguinal hernia repair because of less recurrence,   but it is inferior or equal to sutured technique in case of other post-operative complications   such as chronic pain. This clinical trial set out to compare these two techniques.   Materials and Methods: A total number of 322 cases of unilateral inguinal hernia in participants   older than 18 yea...

We analyze the problem of tessellating an n-sided patch with ideal, maximally-regular internal quadrangulation, featuring a single irregular vertex (or none, for n=4). derive, in closed-form, necessary and sufficient conditions that boundary must meet it to admit quadrangulation this kind, and, if so, provide full description resulting tessellation(s), as functions number edges subdividing side...

Abstract Paper cultural relics such as double-sided printed newspapers and periodicals represent modern heritage. Severe damage embrittlement, decay, dreg generally occur to paper; hence, it urgently needs conservation restoration. Therefore, herein, a new reinforcement method for the fragile paper is proposed with cotton mesh adhesive PVA217 materials. Using computer measured controlled foldin...

It is difficult to develop an algorithm which is able to generate the appropriate mesh around the interfaces in bimaterials. In this study, a corresponding algorithm is proposed for this class of unified structures made from different materials with arbitrary shapes. The non-uniform mesh is generated adaptively based on advancing front technique available in Abaqus software. Implementing severa...

This paper addresses the problem of testing simple hypotheses about the mean of a bivariate normal distribution with identity covariance matrix against restricted alternatives. The LRTs and their power functions for such types of hypotheses are derived. Furthermore, through some elementary calculus, it is shown that the power function of the LRT satisfies certain monotonicity and symmetry p...
