The onset of thermal convection in a finite rotating cylinder is investigated using direct numerical simulations of the Navier–Stokes equations with the Boussinesq approximation in a regime in which spatio-temporal complexity is observed directly after onset. The system is examined in the non-physical limit of zero centrifugal force as well as with an experimentally realizable centrifugal force...

Navigating through an ever-changing and unsteady environment, and utilizing chemical energy, molecular motors transport the cell׳s crucial components, such as organelles and vesicles filled with neurotransmitter. They generate force and pull cargo, as they literally walk along the polymeric tracks, e.g. microtubules. What we suggest in this paper is that the motor protein is not really pulling ...

Ratcheting deformation in association with bulk texture evolution HSLA steel is studied this investigation. The cyclic behaviors and damage modes of the specimens are obtained at room temperature, employing asymmetric stress-controlled tests under various combinations mean stress amplitudes. Bulk measurements done adopting an X-ray diffraction analysis. results exhibit increase strain accumulat...
