The Eagles offense is more dynamic than the Jacksonville Jaguars, so it wouldn't be surprising if the Eagles were more productive on a neutral surface than the Jags' 20 points at Gillette Stadium.
The transversal rigidity of the belt is determined by the transversal elasticity modulus [E.sub.2] which, where the belt folds into a tube, accepts different values for those inserts which are positioned at a higher or lower level than the neutral surface of the belt.
The collection of these points is frequently referred to as the neutral surface. If a straight ball bar is measured while both spheres are positioned above the neutral surface, the ball bar will measure physically shorter than it would if both spheres were positioned below the neutral surface--lengths [L.sub.1] and [L.sub.2] on the right side of Fig.
The system is easy to install and there are currently two types of membrane available--negative surface charge (PVDF) and neutral surface charge (PES).

Residual stresses were estimated measured in this way by Inoue and Kobatake (1) and by Corcoran (2), but their calculations did not take account of the true position of the neutral surface and were based on the assumption that it coincided with the mid-plane of the substrate.
The researchers disregarded the tensile strength of concrete by estimating a neutral surface. Next, they applied translational boundary conditions to ali external nodes that in actuality are connected to adjacent structures.
I ask students not to change the neutral surface with paint or other camouflage, and to retain any printed matter that may appear on the material.
Most noncaustic cleaners currently on the market leave a pH neutral surface with a normal tap water rinse.
Klein of the University of Pennsylvania in Philadelphia studied the behavior of water on charged and neutral surfaces. Even when present in small numbers, water molecules on a neutral surface form microscopic droplets that look and act like their much larger counterparts, they report in the Sept.
An upset over the defending champions, even on a neutral surface, will be harder than it looks.
Once the support is nothing more than a neutral surface of projection and the moving brush nothing more than the prolongation of one's arm, no heterogeneous, imported element can have enough weight to materially destabilize the unity of the picture plane.
