Results of precommercial thinning in very young Applachian hardwood stands


, : Results of precommercial thinning in very young Applachian hardwood stands. Northern Logger and Timber Processor 26(6): 24-25

Crop trees 7-9 yr old of Quercus rubra, Acer rubrum, A. saccharum, Prunus serotina and Liriodendron tulipifera, spaced at about 20 X 20 ft, were released on 3 sites in W. Virginia. Data are tabulated for released and control trees, showing: crown class and av. ht. (8-19 ft) before treatment; and av. ht. and av. d.b.h. 5 yr after treatment. On 2 sites of site index 70 and 80, ht. and d.b.h. were n.s.d. between released trees and controls.

A copper-catalyzed process has been developed for the N-arylation reaction under very mild conditions in the absence of additional ligand. This protocol could not only tolerate an array of thermally sensitive functional groups, but also achieve hi...

We describe magic-angle-spinning NMR methods for the accurate determination of internuclear dipole-dipole couplings between homonuclear spins-(1/2) in the solid state. The new sequences use symmetry principles to treat the effect of magic-angle sa...
