For instance, the DSR allows item designers to produce tooth paste with the appropriate consistency so that it can be squeezed from a tube yet not diminish the toothbrush. The DSR examinations binder put between 2 parallel plates about the dimension of a quarter. One of the plates actions and the equipment gauges the viscoelastic properties of the asphalt.
