If the power is injected using forces proportional to the velocity, such as those common in shear flows, or with a force acting at the largest scales only, the spectrum of

Vibroacoustic responses of a heavy fluid loaded cylindrical shell excited by a turbulent boundary layer3. Laurent Maxit, Mahmoud Karimi, Valentin Meyer,

To control the quality of cylindrical objects (e.g. mechanical pieces, pistons, etc) points are probed on the boundary of the cylinder and the width of the minimum-width enclosing

Therefore, to investigate the biological conse- quences of eAGR3 secretion, we further used recombinant AGR3 protein at the concentration of 5 and 50 ng/ml.As demonstrated here,

Therefore, a resilience indicator must be focused on two aspects: (i) if the connections in the park are enough to withstand a disruptive event, and (ii) if the remaining
