The DSR allows item programmers to create toothpaste with the right consistency so that it can be pressed from a tube however not fall off the toothbrush. The DSR examinations binder positioned in between 2 identical plates about the size of a quarter. Among home plates steps and the device determines the viscoelastic properties of the asphalt.
