| Successful operation of any lava lamp depends on this relationship between the density of water and wax. |
| For this reason, separate mechanisms of acclimation for regulation of stomatal density on adaxial and abaxial surfaces have been proposed. |
| Bone mineral density of the lumbar spine and proximal femur were measured with dual energy x ray absorptiometry. |
| The risk of sensitization to acarids is proportional to their density in the patient's home environment. |
| It is the secret, the mystery of quicksilver, that a metal of such enormous density can yet remain liquid. |
| Bone mineral density was measured at the lumbar spine, radius, hip and femoral neck. |
