In the present work, stable clusters made of multiple sonoluminescent bubbles are experimentally and theoretically studied. Argon bubbles were acoustically generated and trapped using bi-frequency driving within a cylindrical ...

We consider the Cauchy problem for the energy critical heat equation {ut=Δu+|u|4n−2uinRn×(0,T)u(⋅,0)=u0inRn in dimension n = 5. More precisely we find that for given points q 1 ,q 2 ,..,q k and any sufficiently small T ...

In this work we consider the following problem [GRAPHICS] with N/(N - 2) < p < p* = (N + 2)/(N - 2) < q, N >= 3. We prove that if p is fixed, and q is close enough to the critical exponent p*, then there exists a ...

There are the indications that plasma bubbles/flux tube aligned plasma density depletions, produced by Rayleigh–Taylor instability at the bottomside of ionosphere, could rise up to the topside ionosphere and plasmasphere. ...

The steelmaking involves several processes, where it is possible to identify a great variety of phenomena. These process has in his structure the interaction between gas in the form of bubbles and liquid steel. Furthermore, ...
