31. If such differential transport has a divergence, then it results in a change of the charge density . 32. This observation is explained by the charge density wave formations that open the gaps in the Fermi surface. 33. Bond lengths and charge densities are shown as functions of how many hydride ligands are on the central atoms. 34. This depends on the charge density of the negative sulfate and carboxylate anions in the glycosaminoglycan ( GAG ). 35. Here is the electric field, is the magnetic field, is charge density , and is current density. 36. These compounds like heparin possess a negative charge density that allows it to interact and inhibit the coagulation process. 37. When investigating a finite region, however, it is possible that the charge density within the region may change. 38. These two types of exchangers can maintain the charge density of their columns over a pH range of 5 9. 39. They stand apart from other batteries in their high charge density ( long life ) and high cost per unit. 40. Like any density, charge density can depend on position, but charge and thus charge density can be negative.
