Torsion of elastic and poroelastic circular shaft of radially inhomogeneous, cylindrically orthotropic materials is studied with emphasis on the end effects example for extruder. To examine the conjecture of Saint-Venant’s torsion, we consider torsion of circular shaft with one end fixed and the other end free on which tractions that results in a pure torque are prescribed arbitrarily over the fr...

In this paper firt of all we introduce a generalization of torsion freeness of acts over monoids, called -torsion freeness. Then in section 1 of results we give some general properties and in sections 2, 3 and 4 we give a characterization of monoids for which this property of their right Rees factor, cyclic and acts in general  implies some other properties, respectively.

An accurate and consistent approach to the out-of-plane stability design of steel beams structures utilising second-order inelastic analysis with strain limits is proposed. The method implemented using computationally efficient beam elements, ultimate structural resistance defined either by (i) load factor or (ii) at which a limit, determined on basis continuous strength (CSM), attained, whiche...

Acute scrotal swelling is an urgent urologic condition, and its failure in diagnosis is "one of the litigious issues in urologic practice. "1-2 Although acute scrotal pain is due to spermatic cord torsion in 25-35% of cases, the urologist should either rule it out or treat it immediately. 2 We operated a case of acute scrotal edema in a two-day-old boy who had, according to clinical results...

Perinatal testicular torsion (PTT) is a rare entity. The management of PTT is controversial, due to the low viability of the testis and the possibility of bilateral torsion. This is a review of our experience with six cases of PTT, highlighting diagnostic and therapeutic difficulties of this condition.

Background and Aim: Ovarian torsion is one of the rare causes of emergency surgeries during pregnancy. Heterotopic pregnancy is a rare type of pregnancy characterized by embryo implantation in two different locations. occurence of these two complications at the same time is a very rare condition. In this study, we present a rare case of heterotopic pregnancy accompanied by ovarian torsion. Pat...

Seismic activity is associated with crustal stress relaxation, creating inelastic strain in a medium due to faulting. Inelastic strain affects the stress field around a weak body and causes stress concentration around the body, because the body itself has already released stress. Therefore, the understanding of inelastic deformation is important as it generates earthquakes. We investigated aver...

background: the aim of the present study was to evaluate how left ventricular twist and torsion are associated with sex between sex groups of the same age. materials and methods : twenty one healthy subjects were scanned in left ventricle basal and apical short axis views to run the block matching algorithm; instantaneous changes in the base and apex rotation angels were estimated by this algor...
