Aims. We investigate the reconstruction of pulsar magnetospheres close to the light cylinder surface to study the curvature drift instability (CDI) responsible for the twisting of magnetic field lines in the mentioned zone. The influence of plasma dynamics on the saturation process of the CDI is studied. Methods. On the basis of the Euler, continuity, and induction equations, we derive the incr...

Torsional instability of femoral components has not received much attention, and is difficult to detect in conventional radiographs. To test this we designed a system to apply a load in an anteroposterior direction to the head of a femoral component, implanted into a cadaveric femur. Rotation within the bone was measured, using a purpose built transducer, with and without preservation of the ne...

This is a 19-year-old female involved as a passenger in a motor vehicle collision. She was stabilized at a referring hospital then transferred to the level 1 trauma center. Her major injury was to the pelvis. She is haemodynamically stable. This was a closed injury with no leg length or rotational abnormality. She had no bowel or bladder injury. There was instability to compression and distract...

Coupled coaxially stacked toroidal condensates with persistent currents suggest an appealing physical platform for the investigation of various phenomena related to interacting superflows from Josephson effects in regime weak interactions quantum Kelvin-Helmholtz instability merging rings. We experimentally accessible methods prepare states different topological charges two coupled coaxial ring...

The anterior cruciate ligament (ACL) is one of the most important stabilizers of the knee joint. It resists anterior tibial translation and serves as a secondary restraint to internal tibial rotation [1–3]. ACL deficiency frequently leads to symptomatic knee instability, and is associated with both shortand long-term consequences, including meniscal and articular cartilage lesions and progressi...

The nonlinear dynamics of the composite shaft rotor-bearing system are greatly affected by orientation angle layer and its proportion ply, i.e., ratio in laminate. This paper presents a dynamic analysis with pedestal looseness that considers oil film force looseness. Nonlinear phenomena including periodic, quasi-periodic, chaotic motions analyzed. results indicate stiffness damping coefficients...

Wave propagation in ventricular muscle is rendered highly anisotropic by the intramural rotation of the fiber. This rotational anisotropy is especially important because it can produce a twist of electrical vortices, which measures the rate of rotation (in degree/mm) of activation wavefronts in successive planes perpendicular to a line of phase singularity, or filament. This twist can then sign...

Kelvin-Helmholtz (KH) instability plays a significant role in transport and mixing properties of any medium. In this paper, we numerically explore for two-dimensional strongly coupled dusty plasma with rotational shear flows. We study medium using generalized hydrodynamic fluid model which treats it as viscoelastic fluid. consider the specific cases rotating vorticity abrupt radial profiles rot...
