On page 191 in Equation 2 an error appeared, published as:
\begin{aligned} X_{H} & = \left[ {X_{{\dot{u}}} - m} \right]\dot{u} + mvr + mx_{G} r^{2} \left[ {X_{{\dot{v}\dot{v}}} \dot{v}^{2} + X_{{\dot{v}}} \dot{v} + X_{{\dot{r}\dot{r}}} \dot{r}^{2} + X_{{\dot{r}}} \dot{r}} \right] \\ & \quad + \frac{1}{2}\rho LT\left\{ {\left[ {u^{2} + v^{2} } \right] {X'(\beta )} + \left[ {u^{2} + \left( {\frac{1}{2}rL} \right)^{2} } \right]X'(\gamma ) + \left[ {v^{2} + \left( {\frac{1}{2}rL} \right)^{2} } \right]X'(\chi )} \right\} \\ \end{aligned}
The equation should be correctly written as:
\begin{aligned} X_{H} & = \left[ {X_{{\dot{u}}} - m}\right]\dot{u} + mvr + mx_{G} r^{2} + \left[ {X_{{\dot{v}\dot{v}}}\dot{v}^{2} + X_{{\dot{v}}} \dot{v} + X_{{\dot{r}\dot{r}}}\dot{r}^{2} + X_{{\dot{r}}} \dot{r}} \right] \\ & \quad +\frac{1}{2}\rho LT\left\{ {\left[ {u^{2} + v^{2} } \right]X'(\beta ) + \left[ {u^{2}+ \left( {\frac{1}{2}rL}\right)^{2} } \right]X'(\gamma ) + \left[ {v^{2} + \left({\frac{1}{2}rL}\right)^{2} } \right]X'(\chi )} \right\} \\ \end{aligned}
