composition and structure of a three-storied fagus orientalis-dominated forest was investigated in the caspian forests, north of iran. circular sampling plots of 1000 m2 occupied by advance growth and natural regeneration were randomly chosen where the initial cuttings (with shelterwood aim) were performed. abundance of species at different growth stages and quality of seedlings and saplings we...

The effect of a water repellent chemical used in the textile sector on some physical properties wood was investigated this study. Uludağ Fir (Abies bornmülleriana Mattf) and Beech (Fagus Orientalis Lipsky) were as commercial named Ruco-DryEco® (RD), fluorocarbon-free water-based product industry, chemical. This is an 3% aqueous solution industry. So, study 5% 10% RD used. After treatment with s...

the objective of this research is characterizing the effect of nano-zinc oxide (nano-zno) dispersions on leach resistance and contact angle of beech wood (fagus orientalis lipsky). the beech wood was cut into standard dimension, and oven dried after treating with nano-zno solution, based on immersion method. three treating nano-zno solution levels: (o, 20000 and 40000 ppm), and two thermal trea...
