The effects of chemical modification on the biological properties of alder and spruce particleboards
2007 - IRG/WP 07-40363
This study is evaluated by measuring the weight loss, and the ability of white and brown-rot fungi to attack unmodified and modified particleboards manufactured using spruce (Picea orientalis (L.) Link.) and alder (Alnus glutinosa) chips. The chips were reacted with acetic, succinic, maleic and phthalic anhydride at constant temperature for 3 hours then, hot pressed at 150 °C by using phenol for...

Radial flow of Bornmullerian fir (Abies bornmulleriana Mattf.) as affected by wood tapering and the condition of end wall structure of uniseriate ray parenchyma cells
2008 - IRG/WP 08-40441
Amenability to radial permeability of Bornmullerian fir (Abies bornmulleriana Mattf.) was studied on the base of the effects of wood tapering and the structure of end walls of uniseriate ray parenchyma cells. The results showed that the most remarkable culprits of the greatest fluid uptake (as the percentage of void volume filled by the fluid in the radial flow direction, RVVF%) are the lesser woo...
