Magnetic resonance imaging was employed for the first time to visualize gravity sedimentation of kaolin suspensions, allowing internal spatial distribution during be investigated.

Aims. Two interrelated peaks occur in high-frequency power spectra of X-ray lightcurves of several black-hole candidates. We further explore the idea that a non-linear resonance mechanism, operating in strong-gravity regime, is responsible for these quasi-periodic oscillations (QPOs). Methods. By extending the multiple-scales analysis of Rebusco, we construct two-dimensional phase-space section...

It is pointed out that the internal structure of the narrow resonance X(3872) at the

Reducing the radiated noise from ships is becoming increasingly important as ship -builders aim to reduce the disturbance to marine life, passengers and crew. A major contributor is on-board machinery which typically radiates noise to the water column from both structure-borne and air-borne transmission paths. Problematic machinery is often decoupled from the hull by supporting it on resilient ...
