Abstract
  In this work effect of initial alkali charge were investigated on the yield and kappa number of soda beech pulp and alkali consumption pattern. The results indicated that, the regression models are useful for studying the relations between yield, kappa number and alkali consumption. Soda cooking was ...  Read More

Abstract
  In this study Populus alba native clone and Populus euramericana 476 clone trees from Gorgan University educative forest were used. Some applied anatomical and physical properties of these species were determined. Results showed that the juvenility age for both species is approximately 10 years .In both ...  Read More
