WebWe go on defining in three steps an exact localization functor of the derived category L τ: D ( R) → D ( R). (1) Denote by H n: D ( R) → M o d ( R) the usual n -th cohomology, for every n ∈ Z. It is clear that each H n ( −) is cohomological and preserves coproducts. (2) Fix a hereditary torsion theory τ on M o d ( R). The τ -localization functor WebA n adjustment factor can be derived to correct the dry weights of the seedlings grown from any seed weight class to a "normal" value (Aldrich-Blake, 1930, 1932, 1935; Gast, 1937; Mitchell, 1934, 1939).
