Stagewise forward mixing model considering coalescence and redispersion of drops was used to predict the performance of Rotating Disc Liquid-Liquid Extraction Contactors. Experimental data previously obtained in two RDC columns of 7.62cm diameter, 73.6cm height and 21.9cm diameter, 150cm height were used to evaluate the model predictions. Drop-side mass transfer coefficients were predicted appl...

The main effect of axial rotation on the evolution of massive PopIII stars is to trigger internal mixing processes which allow stars to produce significant amounts of primary nitrogen 14 and carbon 13. Very metal poor massive stars produce much more primary nitrogen than PopIII stars for a given initial mass and rotation velocity. The very metal poor stars undergo strong mass loss induced by ro...

Mixing patterns inside a simulated flat bottom digester were imaged using the non-invasive techniques of computer automated radioactive particle tracking (CARPT) and computed tomography (CT). Mixing/agitation was provided using gas (air) recirculation at three different flow rates (Q(g)) of 28.32, 56.64 and 84.96 l/h, corresponding to superficial gas velocities of 0.025, 0.05 and 0.075 cm/s, re...

Ethanol injection and variations of it are a class of methods where two miscible phases-one of which contains dissolved lipids-are mixed together leading to the self-assembly of lipid molecules to form liposomes. This method has been suggested, among other applications, for in situ synthesis of liposomes as drug delivery capsules. However, the mechanism that leads to a specific size selection o...

Using a recently proposed gauge covariant diagonalization of $\pi a_1$-mixing we show that the low energy theorem $F^{\pi}=e f_\pi^2 F^{3\pi}$ current algebra, relating anomalous form factor $F_{\gamma \to \pi^+\pi^0\pi^-} = and neutral pion $F_{\pi^0 \gamma\gamma}=F^\pi$, is fulfilled in framework Nambu-Jona-Lasinio (NJL) model, solving long standing problem encountered extension including vec...
