Roll motion

Interface level control problems exist. and barge pitch motions are usually less than roll motions. In such cases the pitch... 

With a rolling motion, roll the finger in a downward direction toward the eyelashes. Continue this across the entire lid to be sure all glands are "milked" in a downward motion. 

Tremor is one of the characteristic signs of Parkinsonism, but not all patients actually display that symptom. While it is immediately obvious and recognizable, tremor is not necessarily more of a disability than the other symptoms of the disorder. Tremor occurs while the patient is at rest and is reflected mostly in the hands, in spasms entailing a rolling motion of various fingers. Other parts of the body may also be involved in the tremor, notably the lips and the head. While the Parkinson s patient is involved in some task, the tremor may relent for a short period of time. 

In counter-rotating screws, the rolling motion of the screws and the resultant calendar effect produces... 

Extruders that rely solely on the pressure developed by the rotating screws employ hydrostatic pressure as the transport mechanism and are generally high pressure extruders. Those extruders that utilize dragging or rolling motion (for the latter see Section 4.2.2.6.6) feature a localized drag flow transport mechanism and, consequently, the rate of work performed and internal pressure developed are lower. 

Pill rolling motion is a symptom of PD, not a side effect of a medication. 

A remarkable analysis of the role of hydrodynamics in LB depositions was done by de Gennes (1986). This analysis concerns only deposition during removal of the solid substrate, de Gennes recognizes that the only flow pattern that would allow Y-deposition is a split-ejection streamline in the liquid phase. However, he uses as a reference the work of Huh and Scriven (1971), but their hydrodynamic theory predicts a rolling motion in the liquid phase. 

Figure 10.4 Schematic representation of flow patterns near a moving contact line during immersion of a solid substrate into a pool of liquid, (a) Split-injection streamline in phase B and rolling pattern in phase A. (b) Transition flow pattern with motionless interface and rolling motion in phases A and B. (c) Rolling motion in phase B and split-ejection streamline in phase A...
