"level of density" is a correct and usable phrase in written English.
It can be used to describe the degree of compactness or thickness of a substance or material. Example: "The level of density in this concrete mix is too high, which makes it difficult to pour and spread evenly."
But there's an optimal level of density.
But you can't do a rail line absent a certain level of density".
MCM: Do you have a sense that when there is that level of density and actual physical weight, that it acts on the viewer in a different way than the same thing would if it were hollow?
This all appears to cut against the urban planning orthodoxy that a certain level of density – around 30-50 homes per hectare – is necessary to make lively communities that are able to support shops, businesses and public transport.
All quantum chemical calculations were performed at the level of density functional theory (DFT) with B3LYP functional using 6-311G (d,p) basis atomic set.
While fragility has a direct impact on the kinetics of the relaxation process, the minimum level of density fluctuations is unaffected by changes in fragility alone.
We found that a certain level of density-dependency occurred in wet-season range, even under extreme nonequilibrium conditions.
The level of density-dependence matters as well, but only when selection is strong.
Instead, levels of selection, heritability and level of density-compensation matters (Fig. 6).
The level of density-compensation was important in determining the variance in load when there was strong selection, and when genetic variance was lower when the level of density-compensation was low.
There was also an interaction between level of density-dependence and the colour of noise when selection was strong.
