The fit fails unless the expansion is accelerating; driven perhaps by ‘dark energy’. Is the recession of the galaxies slowed down by gravity or speeded up by some repulsive force? To shed light on this question the...

This chapter describes the main parameters and the different techniques used to characterize an anaerobic bioreactor and how to apply the obtained information to learn how to operate it. In this kind of biological systems, the large number of processes, operating parameters and removed compounds involved makes necessary to combine knowledge from both Microbiology and Chemical Reactor Engineerin...
