frictional coefficient
The difference between the computed and Stokes' values gave the frictional coefficient or resistance resulting from the interaction of the cells, with the test surface.
      
The frictional coefficient for plastic was found to be 1.75×10-7 N s m-1 compared with a value of 2.82×10-7 N s m-1 for rhodium metal, which had the largest interaction.
      
Furthermore, sedimentation and diffusion coefficients, Stokes' radii, and frictional coefficient ratios of DNA polymerases α and ? from malignant cells significantly deviated.
      
The following molecular data were determined: sedimentation coefficient s20, ω0=14.47×10-13 sec, diffusion coefficient D20, ω0=3.06×10-7 cm2/sec, partial specific volume=0.701 ml/g, ratio of the frictional coefficient f/f0=1.46.
      
A rod-like shape of the molecule was derived from the calculated frictional coefficient.
      
The frictional coefficient of the C60 layers was determined to be significantly smaller than the frictional coefficient of the GeS substrate.
      
Frictional coefficient-11 (evaluation of degree of coupling, efficiency of energy conversion and membrane parameters)
      
Compared with the frictional coefficient of the NaHA adsorption layer on the BSA monolayer, the values for the NaHA-BSA complex layer were found to be much higher.
      
The surface nanostructure, the adhesion force Fad, and the local frictional coefficient μ of collagen were studied by an atomic force microscope AFM and a lateral force microscope LFM.
      
The first formula corresponds to theKirkwood frictional coefficient formula.
      
Discrepancy between theory and experiment is more prominent for viscosity than for translational frictional coefficient.
      
The resulting frictional forces proportional to the viscosity of the solvent are not included in the frictional coefficient of the beads and hence have to be considered separately as a contribution to internal viscosity.
      
Special attention was given to the frictional coefficient in the early state of the test runs.
      
These parameters include normal and tangential adhesions, frictional coefficient, nodal density, the dimension of local nodal support domain, nodal irregularity, shape parameters used in the radial basis function and the external load.
      
The critical speed to avoid slippage between a roll and web was found to be estimable by applying and extending the concept of "effective" frictional coefficient with the consideration of air-entrainment, which is proposed by Good et al.
      
where I is intactness of rock mass; f is the frictional coefficient of predominant structure surfaces; S is the stiffness of the rock block.
      
Therefore, finding an adhesive and inert coating material that has low frictional coefficient should dramatically reduce the production of wear particles and hence, prolong the life time of the surgical implants.
      
Based upon the model, λcr can be evaluated numerically depending on μ (the frictional coefficient) and c0/a (c0 and a are the sizes of the shear crack and tensile crack, respectively).
      
Finite element results indicate that reasonable changes in the applied force, frictional coefficient and the clearance will not make significant changes in the normalized SIFs.
      
The success of this approach rely on the knowledge of the frictional coefficient which links the frictional force at the ocean floor, either quadratically or linearly, with the current velocity.
