Southern Ontario is one of the most dense regions in the country.

This dense region of roots provides excellent cover for young fish fry.

For example, in a very dense region where many particles are close together the smoothing length can be made relatively short, yielding high spatial resolution.

Even in the less dense regions, stars must have peculiar careers.

This was a dense region of space, a fact further proved by the meteorites which made white scratches across the sky every few minutes.

The resolution elements follow the most dense regions, in a sense.

Star formation occurs in dense regions of dust and gas, known as giant molecular clouds.

A sufficiently dense, and hot, core region will trigger nuclear fusion, thus creating a main-sequence star.

This causes material to clump in the dense regions.

From there, he would enter "a dense, wild and completely uncultivated" region.
