(vertical bar u vertical bar(n) del Delta(4)u) in R-N x R+, n > 0, (0.1) (0, 1) are studied. The present paper continues the study began in [1]. Thus, the following questions are also under scrutiny: (I) Further study of the limit n -> 0, where the behaviour of finite interfaces and solutions as y > infinity are described. In particular, for N = 1, the interfaces are shown to diverge as follows: vertical bar x(0)(t)vertical bar similar to 10 (1/n sec (4 pi/9)) (9/10) t(1/10) -> infinity as n -> 0+. (II) For a fixed n is an element of (0, 9/8), oscillatory structures of solutions near interfaces. (III) Again, for a fioxed n is an element of (0, 9/8), global structures of some nonlinear and analytical methods
