Static spherically symmetric Kalb-Ramond (KR) traversable worm-holes in torsioned spacetime are shown not to exist globally since tor-sion vanishes not only at the wormhole throat but in all spacetime points which means that all components of the KR field vanish identically. With this result Hochberg-Visser result on the non-violation of the weak energy (WEC) condition in the presence of four-d...

The physical meaning of Cosserat, void, and microstretch elastic constants is analyzed and interpreted. Various torsion experiment designs provide a clear path to extract Cosserat elastic constants independently of any dilatation gradient sensitivity the material may have. For void elasticity (with sensitivity to dilatation gradients) there is no known quasi-static modality to demonstrate pheno...

Torsion and infarction of the greater omentum are two rare clinical situations which present as an acute abdomen. Nevertheless, knowledge concerning these two problems can help the surgeon in proper diagnosis and treatment. Since the first report on primary torsion by Eitel in 1899, a few hundred more have been reported and some collective reviews published to date. In this study we will p...

background: testicular torsion is a medical emergency with catastrophic sequelae that deserves the same treatment considerations and concerted efforts in research as any other complicated medical condition. the aim of this study was to investigate the effect of pausinystalia macroceras (pm) bark extract on sperm quality and serum testosterone levels in testicular torsion in a rat model. methods...

Abstract In the framework of Metric-Affine Gravity, existing correspondence between Einstein tensor and energy-momentum matter provided by General Relativity is extended towards a post-Riemannian description in terms torsion nonmetricity fields, which are sourced spin, dilation shear currents matter. this work, we focus on dynamical role traceless part its intrinsic connection with shears, defi...

  Torsion of the gallbladder is a relatively rare surgical disease which mimics acute cholecystitis' symptoms that usually would not be respondable to medical therapies. The torsion would mostly be diagnosed intra-operatively. Cholecystectomy is the treatment of choice. In general in our centre, General Surgery department, Imam Reza hospital, Mashhad, Iran, since 1986 over 14000 cholecystect...
