In Ukraine, the safety of modern thermal power plants depends on reliable operation equipment installed them. Unfortunately, technical condition chimneys is not properly maintained. Of course, modernization basic (boilers, switching to another type fuel) leads a decrease in temperature exhaust gases. An important aspect maintain moisture gases.

Abstract Flow pumping in viscous fluids is of prime importance micro-fluidic applications. Here we show that a single colloidal particle front soft wall, manipulated by external means like an optical tweezer, can pump the ambient fluid. The particle, moving back and forth parallel to produce averaged net flow direction perpendicular wall. Using perturbative scheme, present results. Analysis thi...
