[48], it shows that the transition from hadrons to quarks and gluons has behavior similar to helium, nitrogen, and water at and near their phase transitions in the ratio η/s. Near and below a critical temperature, Tc, the condensates of bosons or fermion pairs behave like superfluids, ...
All real fluids (except superfluids, such as liquid nitrogen) have some resistance to stress and fluid flow, but a fluid that has no resistance to shear stress is known as an ideal fluid or inviscid fluid. A real fluid with a nonzero viscosity is called a viscous fluid. The study of ...

under nitrogen blanketing to exclude oxygen from air. Samples were used for the hot-melt viscosity tests. Further, all the formulations in the examples have been prepared out of solvent. The different ingredients were poured in toluene and mixed for 24 hours to obtain the dissolution. Afterward...
After several hours, the feeds are stopped, the reactor is vented and purged with nitrogen, and the raw dispersion in the vessel is transferred to a cooling vessel. Paraffin wax is removed and polymer dispersion is transferred to a dispersion concentration operation which produces stabilized ...
diffraction experiments on anhydrous melts along the Jd–Di join, at three compositions Jd, Jd50Di50and Di, corresponding to NBO/T=0.0, 0.8 and 2.0, respectively. Structure factorsSX(Q) were obtained from the raw X-ray scattering data using an analytical programme58according to the formula, ...
