The proposed method of asymptotic analysis is employed now to the coupled system defined in Qr. The dependence of the model on the smali parameter s —> 0 occurs in the nonlocal boundary conditions imposed on l~r. The variational form of (42) restricted to Qr is obtained,
0 Vt? e V ,
where Br = Br(x) is a bali of radius R and center at x € .
