The Changes of Leukocyte Rheology, Expression of Leukocyte CD18 and the Concentration of Serum Soluble Intercellular Adhesion Molecule-1 in Patients with Psoriasis
Addition of 2% in mass attapulgite clay into the LFC coating improves greatly the rheological property of LFC coating with the characteristic rheological parameters of τ 0=9.8 Pa, K =2.9, m =0.64.
Laboratory and field application showed that by adding 2% polyglycols into the drilling fluid,there was little change in filtrate loss and rheological property of drilling fluid,but its lubricity was enhanced 60 5%-68.0%,the shale roller recovery ratio reached 82 6%,and recovery value of osmotic ratio reached 84.0%-93 4%.
The rheological properties of the concentrated solution of sulfonated polysulfone with different ion exchange contant (1EC) in DMF, 3D/T, DMF + 0.07 N NaNO3 and 3D/T+ 0.07 N NaNO3 have been determined by using NXS-11 model rotary viscometer under various temperature. Influence of polyelectrolyte effect on experimental results were discussed.
Because the viscoelasticity of polymer solution may enhance oil displacement efficiency, in order to study the viscoelasticity of APS in porous medium and the relationship between it and displacement efficiency under actual reservoir, this paper studies the viscoelasticity and rheological properties of APS and HPAM solution in the rheometer and the porous medium mainly by experiment means, and studies the action of the viscoelasticity of APS on displacement efficiency.
The effect of added poly(ethylene glycol) monolaurate (PEGML) on the formation and properties of lecithin organogels composed of polymer-like micelles was studied by the methods of dynamic rheology and the Fourier transform IR spectroscopy.
The measurements were performed with the aid of a dynamic rheology in different regimes including determination of frequency dependences of rheological parameters, creep, and critical strain and stress at which the gelled systems are destroyed.
Chemical interactions in aqueous concentrated compositions based on natural and technogenic aluminosilicates and binders are studied by the rheology and calorimetry methods.
The viscosity decreased with the blade velocity and such a shear thinning rheological property is similar to that observed for solid-liquid suspensions.
The rheological property change during isothermal and dynamic polymerization of both systems was measured using a rheometer to analyze chemorheology of them.
The rheological property and retrogradation regulation of amylopectins from three types of rice (indica rice, japonica rice and waxy rice) in China were investigated using concentric cylinder viscometer.
The curing properties and rheological behavior of a bismaleimide resin system were studied with differential scanning calorimetry (DSC) analysis and viscometer measurements, respectively.
In the equation, differential viscosity and the first normal stress function are defined to specify the rheological properties of non-Newtonian medium.
The use of a formaldehyde-supplemented medium at the second stage of cultivation improved the rheological properties of ethapolan without reducing its yield.
