This work aimed to evaluate the physical and mechanical properties of 30 Southern-Brazilian woods, interrelationships and similarity of these properties. For the physical properties were evaluated the basic density and shrinkages (radial, tangential and volumetric). For the mechanical properties were evaluated the static bending, parallel compression, perpendicular traction, shear, splitting, ...

The aim of this study was to evaluate the effect of eucalyptus harvesting in the physical-hydric attributes and carbon storage in Typic Quartzipisamment. The study was conducted with seven years old Eucalyptus urograndis stand, in Dom Aquino, MT, Brazil. The evaluations were conducted in two seasons (wet and dry), with soil sampling at depths of 0-0.2, 0.2-0.4, 0.4-0.6, 0.6-0.8 and 0.8-1.0 m, ...

The solid wood bending process is aided with the use of pre-treatments, which aims to control the main wood quality parameters required for technique efficiency. Such parameters related with anatomic and chemistry properties of woods, may be handled by establishing temperature and moisture content values compatible with the needed proceedings. In this context, an important factor is associated ...
