Fire Tetrahedron A four-sided, solid geometric figure Uiat resembles a pyramid, with one of the sides forming the base. Each side indicates one of the tour elements required to have fire. 

Figure 6. Complete subgroup lattice of continuous point groups. Solid circles represent point goups that can be represented by geometrical figures Ki, (sphere), (cylinder), Cw (cone). Open circles represent point goups that cannot be represented by geometrical figures. Schonflies notations are accompanied by Hermann-Mauguin (international) notations in brackets.

FIGURE 5.9. Assembly of llie orbital diagram for tetrahedral II4 from tliose of two H2 units. (The solid lines in this diagram which are associated with ihe geometrical figures iire used to help the reader visuali/c the molecular geometry. The bonds between connected atoms, usually depicted by lines have been left off for clarity.)... 

Esthetic considerations it is the molecular counterpart of the simplest of the five platonic solids, the tetrahedron, the octahedron, the cube or hexahedron, the icosahedron, and the dodecahedron. The (hydro)caibon counterparts of these geometric figures are ... 

Figure 1. Quasiclassical cross-sections for the reaction D -I- H2 (w — 1,2 — 1) DH (v — 1, /) -f H at 1.8-eV total energy as a function of/. The solid line indicates results obtained without including the geometric phase effect. Boxes show the results with the geometric phase included using either 9o = 0 (dashed) or 9o = 11.5 " (dotted).

Figure 4.15 Geometrical representation of the temperature variation of the actual volume (solid line) and the occupied volume (broken line). The shaded difference indicates the free volume which decreases to a critical value at T .

For determining in solid or hollow round sections it is essential to first determine the self geometric mean distance, of the conductors which varies with the thickness / (annulus) of the conductor, approaches its outer radius, ri. in an infinitely thin conductor and to O.TTSri in a solid bar. This variation, in the form of D lr is drtiwn in Figure 28.21, as a function of r,// . 

Dose is related to the amount of radiation energy absorbed by people or equipment. If the radiation comes from a small volume compared with the exposure distance, it is idealized as a point source (Figure 8.3-4). Radiation source, S, emits particles at a constant rate equally in all directions (isotropic). The number of particles that impact the area is S t Tr where Tr is a geometric effect that corrects for the spreading of the radiation according to ratio of the area exposed to the area of a sphere at this distance i.e. the solid angle - subtended by the receptor (equation 8.3-4). 

FIGURE 4-29 Cottrell plot of the chronoamperometric response for 1 x 1(T3M Ru(NH3)63 + at a Kel-F/gold composite electrode. Points are experimental data, the solid line is the least-squares fit to theory. Dashed lines are theoretical Cottrell plots for a macroelectrode with active area equal to the active area of the composite (curve a) and to the geometric area of the composite (curve b).
