WitrynaThis guideline presents a process to assess and control elemental impurities in the drug product using the principles of risk management as described in ICH Q9. This process … Witryna4 lip 2024 · An edge dislocation in a crystal causes the planes of atoms in the lattice to deform where the extra plane of atoms begins (Figure 12.4. 2 ). The edge dislocation frequently determines whether the entire solid will deform and fail under stress. Figure 12.4. 2: Edge Dislocations.
