Oscillation of second-order nonlinear differential equations with a damping term

This paper concerns the oscillation of solutions to the differential equation $$ (r(t) x'(t))'+ p(t) x'(t) + q(t) g( x(t) ) =0, $$ where $xg(x)$ greater than 0 for all $x eq 0$, $r(t)$ greater than 0 for $tgeq t_{0}$ greater than 0. No sign conditions are imposed on $p(t)$ and $q(t)...
