Abstract: 
  We obtain  Kamenev-type oscillation criteria for
 the second-order quasilinear  differential equation
 $$
 (r(t)|y'(t)|^{\alpha-1}y'(t))'+ p(t)|y(t)|^{\beta-1}y(t)=0 \,.
 $$
 The criteria obtained extend the integral averaging technique and
 include earlier results due to Kamenev, Philos and Wong.
