In order to find out at which length scale Lc micro effects (scaling effects in the continuum range) occur, we designed an experimental set-up with a slender cone (cone angle 14°) imbedded in a sleeve as the geometrical counter part.

We report numerical simulation of pure continuum-based laminar gas micro-flow convection with steep density gradients, which cause, for the case of heated air, flattening and rate of flattening of axial velocity profile. This flattening is similar to

Experiments in micro-flow devices almost always show deviations compared to the corresponding situations in macro-systems. Often special “micro-effects” are proposed to explain these unexpected results. However, based on a nondimensional form of

1st International Conference on Microchannels and Minichannels.
Two different experimental set-ups are suggested which both have the advantageous features that channels of continuously varying size between mini- and microchannels are realized, that these channels are formed between macroparts without any need for

Short reaction paths, small amounts of reactants as well as fast and effective changes in reaction conditions are outstanding features of microreaction systems. These characteristics are of interest especially with respect to very fast consecutive re

This paper investigates the qualitative behaviour of single-phase laminar convection for microchannels and conventionallysized channels formed between two parallel plates, captured by a numerical simulation on water flow. The convection parameters ar

The presence of verotoxin-producing strains of Escherichia coli (VTEC) was examined in six children with haemolytic uraemic syndrome and one child with haemorrhagic colitis. Stools were screened for strains of serogroup O157 on sorbitol-MacConkey aga

Summary Seventy-one of 73 E. sakazakii strains isolated in Czechoslovakia produced Tween 80 esterase; its production was slower and less intensive than in Serratia , vibrios and aeromonads. The E. sakazakii strains did not produce lecithinase (yolk r
