[′lim·ət·iŋ ‚den·səd·ē]
(physical chemistry)
The density of a gas when the ratio of density per unit pressure is extrapolated to zero pressure, the point at which a gas exhibits ideal-gas behavior.

Until now, the access rate per channel for memory slots decreased as the memory bus speed increased, limiting density build-up.
We evaluate a composite index of fitness, Laughlin's (1965) capacity for increase ([r.sub.c]), under near-natural conditions including a near-optimal density and a limiting density sufficient to reduce fitness in the parental populations by approximately 50%.
Fitness in the [F.sub.2] almost exactly fits the expectation under an additive-dominance model, indicating little contribution of epistasis to genetic differences among populations in the expression of fitness at limiting density. Thus, under stressful conditions, the advantages to fitness gained by increased heterozygosity clearly outweigh any disadvantages incurred through a breakdown of favorable genic interactions.
