The definition of these zones for a pool of variables (OC, N, SMB, LOM, CEC) is useful at 3 levels: (1) to record the initial values of the measured variables for each plot, (2) to integrate these zones as blocks in experimental design for future experiments, and (3) to focus analysis of specific biological mechanisms such as activity of micro-organisms.
Four molecular descriptors were selected from a pool of variables using genetic algorithm, and then used to built a QSAR model for a series of 1- azacyclyl -3-arylsulfonyl-1H-pyrrolo[2,3-b]pyridines as 5-HT6 receptor agonists or antagonists, useful for the treatment of central nervous system disorders.
