Introducing chain branching and unsaturation, particularly of cis double bonds, reduces ℓc and thus increases v / a0ℓc. Similar effects occur when the effective volume, v, of the chains is increased due to the penetration of organic molecules such as low MW alkanes into the chain regions.

Single-acting cylinders compress gas in only one direction of piston travel. They can be either head end or crank end. Double-acting cylinders compress gas in both directions of piston travel (see Fig. 6).

In geometry, circle packing is the study of the arrangement of circles (of equal or varying sizes) on a given surface such that no overlapping occurs and so that no circle can be enlarged without creating an overlap. The associated packing density, η, of an arrangement is the proportion of the surface covered by the circles.
