Flat Modules and Homological Dimensions,ng upon the species and time of year. Traditional methods to control pitch problems include natural seasoning of wood before pulping and/or adsorption and dispersion of the pitch particles with chemicals in the pulping and papermaking processes, accomplished by adding fine talc, dispersants and othe

Some of the organochlorine compounds are found to be toxic, mutagenic, persistent, bioaccumulating and cause harm in biological systems..Earlier measures taken by the pulp and paper industry to solve the chlori

Forest tree biotechnology,ate resources as metallic ores, trees have the potential to be modified genetically, essentially transmuting lead into gold. Increasingly, modern alchemists are applying the tools of biotechnology in efforts to reduce the biological constraints on forest productivity. Several new methodologies being
