A little Googling on comp.text.tex turned this up:

\section*{Mathematical Model}

The application of poroelasticity to the consolidation of brain and
neoplastic tissues is well established.  Considering brain and
neoplastic tissues as homogeneous, isotropic, poroelastic materials
and assuming infinitesimal deformation, the governing differential
equations are
\begin{linenomath} %%<<----- NOTICE
\begin{gather}
G \; \nabla^2 \vec{u} + \frac{G}{1 - 2 \nu} \; \nabla (\nabla \cdot
\vec{u}) - \alpha \; \nabla p = 0 \label{Naviers_equations} \\[6pt]
%
\alpha \frac{\partial e}{\partial t} + \frac{1}{M} \frac{\partial p}
{\partial t} - \kappa \;  \nabla^2 p = L_{p} \frac{S}{V} (p_{e} - p),
\label{pressure_diffusion_equation}%
\end{gather}
\end{linenomath} %%<<----- NOTICE
where the variable $\vec{u}$ is the displacement vector of the
tissue, $p$ is the interstitial fluid pressure, and $e = \nabla \cdot \vec{u}$ is the dilatation.

\end{document}

Hope that helps.
