| For this reason, separate mechanisms of acclimation for regulation of stomatal density on adaxial and abaxial surfaces have been proposed. |
| Bone mineral density was measured at the lumbar spine, radius, hip and femoral neck. |
| Successful operation of any lava lamp depends on this relationship between the density of water and wax. |
| The surface tension of water is increased, and even the density of air surrounding the Earth ebbs and flows like the tides in the sea. |
| Inhalant users exhibited greater density of familial alcoholism and aggressiveness than nonusers. |
| The idea of lush fertility is further emphasized by the density of the well-watered clover crop that fully occupies a quarter of the foreground. |
