In this section, we present a derivation, based on a hydrodynamic variational principle, of a two-dimensional fluid characterized by the density of intrinsic angular momentum \(\ell \). We assume that the internal energy density of the fluid \(\epsilon (\rho ,s,\ell )\) depends on the ...
theEnglerscale is based on comparing the flow of the substance being tested to the flow of another substance - water. Viscosity inEnglerdegrees is the ratio of the time of a flow of200 cubic centimetersof the fluid whose viscosity is being measured - to the time...
(AO)mmoieties may be randomly bonded or block-bonded; R2is a residue after removal of one hydrogen atom from a hydrocarbon polymer whose essential constituent monomer is butadiene in which the butadiene is present in a proportion of 50% by weight or more based on the weight of R2, or ...
36, we examined the spatial localization of RHOA activity and its potential involvement in cell motility at elevated viscosities. Using a Förster resonance energy transfer (FRET)-based RHOA-activity biosensor2,20, we found that cells on collagen-I-coated 2D surfaces exhibited higher RHOA ...
Based on heavy-ion data from these two colliders and theoretical modeling, lots of efforts are paid to uncover the fundamental properties of the quark gluon plasma [39–43]. The analysis of the elliptic flow v2 in the ultra-relativistic heavy-ion collisions shows that QGP behaves like a ...
and based on these data, several attempts to construct a general analytic formulae for obtaining the coefficient have been tried, where among them, the formula obtained by So and Klaus (see Equation1) is regarded as one of the best [21,22]. Theαvalue is another way to denominate pressure...
Values calculated from the formula are about an order of magnitude higher than the experimental ones, which suggests that the chains were not fully extended at steady state. The second analysis predicts the strain necessary to completely unfold a randomly coiled chain. The analysis is based on a...
Moreover, a strong correlation between viscosity and PET has also been established, mainly ascribed to the viscosity- dependent molecular conformational changes36–38 or diffusion rate variations39,40 of the donor/acceptor system. However, to our know- ledge, no studies on PET-based fluorescent ...
A brief review of the effect of Newton's macroscopic dynamic shear viscosity on the rotation of a cylinder and a ball in a viscous fluid is presented. The approximate nature of some of Stokes' formulae is discussed, and formulae from elementary viscosity theory are given. The concept of mo...
Organic emulsion-breaking formula and its use in treating well bores drilled in oil-base mud An organic based emulsion-breaking formulation for use in treating well bores drilled in oil-bearing mud that is not eco-toxic and is optimally compatible with formation fluids comprises A Audibert-Hayet,...
