We study the blow-up behavior for positive solutions of a reaction–diffusion equationwith nonnegative variable coefficient. When there is no stationary solution, we show that the solution blows up in finite time. Under certain conditions, we then show that any point with zero source cannot be a blow-up point. © 2012 Elsevier Ltd. All rights reserved.

Abstract The article presents parametric analysis regarding the impact of subgrade and backfill stiffness on values distribution bending moments in structural elements a small integral box bridge made cast situ reinforced concrete. analyzed parameters are modulus reaction under behind structure (k v k h ). At beginning, author selected parts design. In particular, focuses method modeling struct...

In the field of civil engineering and architecture, concept symmetry has been widely accepted. The bridge can be treated as a typical symmetrical structure buildings. Among them, Subgrade identified an important part to bear vehicle loads. Severe pavement problems service capabilities will caused by bridge–subgrade transition section. Therefore, setting rigid–flexible is method solve this probl...
