It is shown that when the drop is dislodged, the calculated hydrodynamic force is equal to the adhesion force and corresponds to the maximum of the pulsation radial velocity (parallel to the disc) calculated at the location of the drop mass centre.
Both boundaries henceforth have equal propensities for adhesion, and this precludes the recycling point from ever leaving the contact area.
It is possible that all inflammatory cells — including monocytes, neutrophils, lymphocytes, and mast cells — contribute to the pool of cytokines, and thus are equal in enhancing adhesion molecule expression and leukocyte infiltration.
However, some degree of cell polarity is mandatory for cell migration [3], as equal growth of adhesions and contractility in both front and rear would preclude the breaking of symmetry that is required for motility.
Certain formulations of the XG/GG/HA hydrogel membranes reduced tendon adhesion with equal efficacy but without reducing the tendon strength compared to Seprafilm.
For analysis of cell cell adhesion, the equal number of examined cells was plated on soft agar.
The critical adhesion strength is equal to 5200 MPa.
With the surface area being 6.89 nm2, we obtain a normalized adhesion energy approximately equal to 440 mJ/m2, which is in a good agreement with experimental results which are reported as 380 and 450 mJ/m2 [15,16].
A significant difference was found only in the pull-off force F; experiments with a preload P < Pb resulted in a change in pull-off force F from 2.6 to 1.9 N, which is equal to a loss in adhesion of approximately 30%.
Strictly speaking, the pattern of the refection contrast (frequency and amplitude) in case of cell adhesion are not equal to the case of polystyrene bead because of the difference of the refractive index, the angle of reflection surface, and so on [ 19].
