The basic effects on the flow induced by yaw-angle and curvature can easily be recovered from the present solution.
The search for tractable models led to the study of the free motion of a particle (the geodesic flow) on surfaces of constant negative curvature.
These represent the directions of lines of zero normal curvature (kn = 0) within the folded surface.
In the radial situation, explicit solutions for a situation in which mean curvature flow is coupled to elasticity are presented.
This then leads to a simple and elegant iterative scheme because we have a linear relationship between curvature and normal velocity.
This ring, as well as being interventricular, is also atrioventricular at its initial location within the inner curvature of the heart.
These, when held at their extremities, he said, naturally accommodate the curvatures of parabolic lines.
Indeed, in the approximation of the curvature leading to (17) we disregarded dfo/dx in comparison with unity.
