Torsion Pairs in Cluster Tubes
We give a complete classification of torsion pairs in the cluster categories associated to tubes of finite rank. The classification is in terms of combinatorial objects called Ptolemy diagrams which already appeared in our earlier work on torsion pairs in cluster categories of Dynkin type A. As a consequence of our classification we establish closed formulae enumerating the torsion pairs in clu...
متن کاملApproximate Closed-form Formulae for Buckling Analysis of Rectangular Tubes under Torsion
The buckling torque may be much less than the yield torque in very thin rectangular tubes under torsion. In this paper, simple closed-form formulae are presented for buckling analysis of long hollow rectangular tubes under torsion. By the presented formulae, one can obtain the critical torque or the critical angle of twist of the tube in terms of its geometrical parameters and material constant...
متن کاملNumerical Study on the Crushing Behavior of Square Tubes Under Three Dimensional Oblique Loading
This study aims to numerically investigate on the crashworthiness of thin-walled square tubes by consideration of 3-D oblique loading. In this type of loading, direction of loading is defined by using two spatial angles relative to the position of the tube. To this aim, finite element (FE) analysis is employed to simulate the loading for 8 different numerical models with different loading orien...

متن کاملIsolated Torsion of Bilateral Fallopian Tubes Combined with Tubal Endometriosis: a Case Report
Torsion of the fallopian tube is less frequent. Indeed, isolated bilateral fallopian tube torsion is rare and often diffi cult to diagnose. The etiology of fallopian tube torsion is still uncertain, especially when this is not associated with torsion of the ovary. We present a case of the torsion of isolated bilateral fallopian tube combined with tubal endometriosis. A 30-year-old woman present...
