Center of a ring

Pales two curvatures are positive, and, at rc, p is a minimum in the plane defined by the axes corresponding to the positive curvatures p is a maximum at rc along the third axis which is perpendicular to this plane. The (3, + 1) critical points are found at the center of a ring of bonded atoms. 

The CD signs of the ICD of P-CDx complexes with mono-, di-, and triazanaphthal-enes in aqueous solutions depend on the polarization directions of these azanaphthal-enes. The polarization assignments come from the CNDO/S-CI calculation 165) coupled with the MCD data of these azanaphthalenes 165). In the first place, the origin of the coordinates was choosen in the center of a ring of P-CDx that is assumed to have a 7-fold symmetry axis. Next, ep which is put at the origin of the p-CDx-fixed Cartesian coordinates, is expressed by the spherical polar coordinates (Fig. 23). 

Martin and Law [33] carried out accurate measurements using several probe designs made of thermistors elements 0.2 mm in diameter and 0.35 mm long with pair of leads 0.02 mm in diameter. The thermistors were either held by their connecting wires in the center of a ring (60 mm in diameter) to minimize disturbance of the sound field, or mounted at the end of a thin rod, or supported in a chamber filled with castor oil (a system similar to Fry s device), or embedded in... 

This delay is composed of a hollow metal rod or bamboo filled with wet beans, rice or peas. The tube is inverted and placed in the center of a ring of igniter material and a small vial of water or acid is tied to the tube. When the wet beans expand, they lift and topple the tube, thereby spilling the acid or water onto the igniter causing combustion. 

Ion trap A mass analyzer that traps all ions from a pulse of ionization at the center of a ring and cap electrode structure energized with DC and radio frequency (rf) fields. Ions of different masses are accelerated out of the trap to an external detector by selective addition of energy.
