Equation (7) in the paper should have been

\begin{matrix} \frac{V_{θ}}{- D} = \frac{1}{- D} (Q_{θ} + \frac{\partial M_{r θ}}{\partial r}) = \frac{\partial}{r \partial θ} (\frac{1}{r^{2}} \frac{\partial^{2} u}{\partial θ^{2}} + \frac{1}{r} \frac{\partial u}{\partial r} + \frac{\partial^{2} u}{\partial r^{2}}) + (1 - ν_{p}) \frac{\partial}{\partial r} (\frac{\partial^{2} u}{r \partial θ \partial r} - \frac{1}{r^{2}} \frac{\partial u}{\partial θ}) = 0 \\ \frac{V_{r}}{- D} = \frac{1}{- D} (Q_{r} + \frac{1}{r} \frac{\partial M_{r θ}}{\partial θ}) = \frac{\partial}{\partial r} (\frac{1}{r^{2}} \frac{\partial^{2} u}{\partial θ^{2}} + \frac{1}{r} \frac{\partial u}{\partial r} + \frac{\partial^{2} u}{\partial r^{2}}) + \frac{1 - ν_{p}}{r} \frac{\partial}{\partial θ} (\partial^{2} u... \end{matrix}
