Summary Removal of lumen water by dewatering using supercritical CO 2 offers an alternative method to mitigate cellular collapse in susceptible hardwoods compared conventional timber drying methods. The anatomy Eucalyptus nitens was quantitatively measured light microscopy, SEM and micro-CT provide understanding the mechanism during drying. These measurements were then used recalibrate a previo...

Abstract Wood is a hygroscopic material that can reach an equilibrium moisture content when ambient temperature and relative humidity are constant. Moisture affects all properties of wood, as well its preservative treatment. The behavior wood be attributed to the hydroxyl groups constituents. Since hemicellulose shows greatest water affinity, it considered main responsible for ingress into mass...

Hardness is a key mechanical property of flooring materials. In this study, the performance veneer floorings (with top layer thickness 0.6 mm) was investigated by dynamic hardness tests, comparing it with those traditional engineered wood 3 and solid floorings. Two hardwoods commonly used on flooring, viz. Quercus robur L. Hymenaea courbaril L., two fast-growing hardwoods, Eucalyptus globulus L...

This study investigates the supply and demand structure of the hardwood stumpage market in the South Central United States for the period 1981-1996. Three stage least squares regression is used to estimate parameters in a simultaneous equations model of pulpwood and sawtimber stumpage markets for mixed hardwoods, oak, and total hardwoods. Stumpage prices are generally non-significant. Hardwood ...
