21. September 1987 in Trier, Germany ) was a theoretical physicist and professor of rheology . 22. The existence of the bubble shape hysteresis has important consequences in interfacial rheology experiments involving bubbles. 23. He was the first recipient of the Bingham Medal from the Society of Rheology in 1948. 24. The solubility of hydroxide in ringwoodite is important because of the effect of hydrogen upon rheology . 25. McNutt has made notable contributions to the understanding of the rheology and strength of the lithosphere. 26. Rheology or viscosity can often be a strong indicator of the molecular structure and molecular mobility.27. This added water to the sample makes it impossible to conduct rheology experiments under anhydrous conditions. 28. Another major component of durum wheat is protein which plays a large role in pasta dough rheology . 29. This property is named pseudoplasticity or shear thinning; the study of such matters is called rheology . 30. Fumed silica is commonly used as a rheology agent to make otherwise low-viscous fluids thixotropic.
