For instance, the DSR makes it possible for product programmers to create tooth paste with the right consistency to make sure that it can be pressed from a tube but not fall off the toothbrush. The DSR examinations binder positioned in between 2 identical plates regarding the size of a quarter. Among the plates relocations and the maker measures the viscoelastic residential properties of the asphalt.
