We did drop Rise Against Racism week due to staff problems, but instead we celebrated Black History Month, and next year we have plans to celebrate One World Week and to hold a concert as part of the Love Music, Hate Racism campaign".
The Russell 2000 small-cap index continued to rebound from Friday's drop, rising 0.4% as of midday.
A non-uniform dispersed phase drop size distribution results in non-uniform drop rise velocities, which make a significant contribution to the dispersed phase axial mixing.
The simulation results were rationalized in terms of biofilm thickness, bed local porosity, gas-phase substrate residual concentration, and pressure drop rise in biological fixed-bed filters.
An experimental study of transient drop rise velocities and mass transfer rates was carried out in the system toluene/acetone/water which is known to show interfacial instabilities.
The rate of transfer of a solute between a single drop, rising or falling at intermediate drop Reynolds numbers (10⩽Re⩽250), and a continuous liquid phase, has been predicted by the solution of the fundamental fluid flow and mass transfer equations.
The transient drop rise velocities were used to quantify the Marangoni effect since the drag coefficient depends on the strength of the Marangoni convection patterns caused by interfacial tension gradients.
The code captures and reproduces the characteristic experimental results: the two-step acceleration behaviour, the temporary reduction of the drop rise velocity, and the enhancement of mass transfer depending on the initial solute concentration.
