Blow-up for a semilinear heat equation with moving nonlinear reaction

We study the behavior of solutions of the semilinear problem $$\displaylines{ u_t=u_{xx}+(1+(T-t)^{-\alpha}\chi_{\{|x|<(T-t)^{1/2}\}}) u^p,\quad x\in\mathbb R,\; t\in(0,T),\cr u(x,0)=u_0(x)\ge 0, \quad x\in\mathbb R, }$$ with $\alpha>0$ and p>0 We describe, in terms of the parameters...
