Abstract: 
 The existence of positive solutions of a two-point boundary value
 problem for a second order differential equation is investigated.
 By using indices of convergence of the nonlinearities at zero and at
 positive infinity, we providea priori upper and lower bounds for 
 the slope of the solutions are also provided.
