Biochemimechanical pulping of hornbeam chips with Phanerochaete chrysosporium

open access: yesBioResources, 2012
The effect of fungal pretreatment of Hornbeam (Carpinus betulus) wood chips on the performance of treated pulps was studied. The chips were pretreated with P. chrysosporium BKM-1767 fungus at 1, 2, and 4 weeks using an inoculation temperature and relative humidity of 39 oC and 65%, respectively with two pulping times (80 and 90 min) and three sodium ...

Bending Creep Behavior of Hornbeam Wood

open access: yesDrvna industrija, 2017
This study examined the effect of altitude on bending creep behavior of hornbeam lumber (Carpinus betulus). For this purpose, 9 hornbeam trees from three different altitudes (400, 800 and 1100 m) in the northern forests of Iran were selected. Clear samples were cut from mature wood in diameter at breast height (DBH). 108 prepared samples (dimensions: 2.
