Capillary pressure in softwoods
Wood Science and Technology, 1981To predict the capillary transport of free liquid during the drying of softwood, it is essential to have knowledge of capillary pressure as a function of moisture content. The dependence of the capillary pressure on the wood's moisture content is predicted with a mechanistic model and measured for isothermal moisture movement in the tangetial direction.

SOFTWOOD GRAFTING IN JACKFRUIT
Acta Horticulturae, 2011Jackfruit is one of the tropical fruits with multiple uses. Huge variability exists in this crop due to seed propagation. Vegetative propagation will help in fixing the characters of superior types. A study on softwood grafting in jackfruit was conducted at the Department of Horticulture, University of Agricultural Sciences, Dharwad by taking up ...

ACS Sustainable Chemistry and Engineering, 2019
Previous work has shown that sulfonation post-treatment employed at a temperature of 130–140 °C modifies the lignin in steam-pretreated softwood to improve the ease of hydrolysis of the resulting “post-treated” substrate.

Fracture behaviour of softwood
Mechanics of Materials, 2003Abstract In design wood is regarded as a brittle material, depending on the stress direction, duration of loading and moisture content. The usual presumption is that wood is perfectly brittle–elastic (linear elastic fracture mechanics, LEFM), or that its behaviour mimics other materials such as concrete.

Economic Geography, 1934
T nHE growing international trade in wood, pulp, and paper between the countries of the world has made the question of the forest resources of the world, and especially the softwood resources of the world, a matter of common interest. This interest centers around the two continents-Europe and North America-where almost ninetenths of the world's ...

CONSOLIDATION OF SOFTWOOD ARTIFACTS
Studies in Conservation, 1971Consolidation of decayed wooden artifacts can be achieved by impregnation with epoxy prepolymer dissolved in a mixture of toluene and glycidyl ether and subsequent polymerization in situ. The principles of selecting the successful method of application are discussed, and the details of the procedure given.
