4. Use of Hevea brasiliensis Rubberwood for Glulam Beam Production
ABSTRACT In Brazil, Hevea brasiliensis plantations are principally destined for latex production. In the national literature however, there are few studies on the mechanical properties of rubberwood. This study aimed to evaluate the potential of rubberwood in the manufacture of glulam beams (VLC), through the use of pieces of sawn wood of H. brasiliensis clo

5. Physical Properties of Wood from Steamed Eucalyptus grandis Logs
ABSTRACT This study aimed to evaluate the effect of log steaming on the physical properties of Eucalyptus grandis Hill ex Maiden wood. Logs with diameters between 20 and 25 cm and length of 2.9 m were studied. Half the logs were maintained in their original condition, and the other half were steamed at 90 °C for 20 hours. Later, the logs were sawn into flat

10. Qualidade da Madeira Serrada e dos Painéis Colados Lateralmente Obtidos de um Plantio de Eucalyptus saligna Smith Visando o Segmento Moveleiro / Quality of the Sawnwood and Glued Panels Obtained of a Eucalyptus saligna Smith Plantation for Furniture Industry
In this research were studied thirty trees of Eucalyptus saligna Smith wood, sampled in a twenty year-old plantation located in Seropédica/RJ. Each tree supplied a log with 2.30 meters in length for the study of the sawn process and panels production (PCLs). The processing of the logs was made in the LPZ Madeiras and Artefatos Ltda sawmill - Piraí/RJ, bein

11. EstimaÃÃo de ParÃmetros GenÃticos, FenotÃpicos e Ambientais para a Qualidade da Madeira de Eucalyptus em Ãrvores Vivas. / Estimation Of Genetic, Phenotypic And Environmental Parameters For Eucalyptus Wood Quality In Living Trees.
The evaluation of the technological characteristics of wood, in most times, is accomplished through destructive methods. But, that process make it impossible the evaluation of a large number of genetic materials. So, the utilization of non-destructive methods makes it possible to evaluate a large amount of trees, allowing a more intensive selection of trees

12. Desenvolvimento e avaliação de um protótipo classificador de tábuas usando técnicas de visão artificial / Development and evaluation of a prototype for sawn wood classification using artificial vision technics
Much effort has been expended by researchers to apply automation to productive processes. The sawn wood industry has a promising place in this activity, because lumber is a raw material for products with increasing demand, such as furniture, which requires high quality pieces. The quality of the lumber is determined by the defects it presents and some charac
