WebThe resulting capacitance can be measured: it is dependant upon the cell type and is directly proportional to the membrane bound volume of these viable cells. Aber’s technology converts capacitance into a live biomass reading, typically cells/ml or g/l. However, other units can be derived from the raw capacitance measurements; these may be ... WebTo demonstrate the use of this correction factor to estimating biomass density, consider the following example: Broadleaf forest with a VOB 30 = 100 m 3 /ha and weighted average wood density; WD = 0.60 t/m 3. Step 1 Calculate the VEF from Eq. 3.1.5: = 1.40. Step 2 Calculate VOB 10: = 100 m 3 /ha x 1.40 = 140 m 3 /ha.
