The buoyancy of eggs and embryos is associated with successful development in pelagic fish. Buoyancy is the result of oocyte hydration, which depends on the osmotic force exerted by free amino acids (FAA) generated by yolk ...

We consider the nonlinear Schrodinger equation epsilon(2)Delta u - V (x) u + | u|(p-1) u = 0, x is an element of R-N, with superlinear and subcritical nonlinearity. Assuming that the potential is radially symmetric ...
