Estimation of mechanical properties of standing trees by bending test II. Variation of tree-trunk stiffness associated with radial growth

, : Estimation of mechanical properties of standing trees by bending test II. Variation of tree-trunk stiffness associated with radial growth. Mokuzai Gakkaishi = Journal of the Japan Wood Research Society 32(11): 860-867

MOE of a tree stem, determined by the bending test proposed previously and assuming uniform mechanical properties across a stem, is an apparent value. A theoretical analysis is made of the variation in MOE between earlywood and latewood and between juvenile wood and mature wood.

Background and Aim: Epidemiological studies have suggested an association between higher body iron stores and coronary artery disease (CAD), but recent trials have reported conflicting data on the role of ferritin in CAD. To assess these findings,...
