Abstract: 
 In this article, we show the existence of positive
 solutions  for boundary value problems with integral boundary
 conditions  and sign changing nonlinearities. By using a fixed point
 theorem in double cones, we obtain sufficient conditions for the
 existence of two positive solutions.
