1. Production of kraft pulp from Ochroma pyramidale wood
RESUMO O Brasil se destaca no cenário internacional em relação a produção de celulose de fibra curta. Apesar da grande biodiversidade brasileira, essa produção está baseada em clones de espécies exóticas de Eucalyptus. Nesse contexto, pode haver grande potencial na avaliação de novas fontes de fibras da flora brasileira, incluindo a região amaz�

2. Influence of the climate on productivity and the eucalyptus drought response and a proposal for maximizing wood productivity in function of soil attributes in Brazil
Resumo Os ganhos genéticos dos programas de melhoramento do eucalipto diminuíram em comparação com as décadas anteriores, enquanto a produtividade reduziu nos últimos anos. Essa queda é atribuída principalmente às mudanças climáticas, que, segundo estudos, têm limitado a produtividade e alterado a adaptação das espécies florestais. Além disso

3. BEHAVIOR OF THERMALLY MODIFIED WOOD TO BIODETERIORATION BY XYLOPHAGE FUNGI
ABSTRACT Thermally modified wood undergoes chemical, physical, and mechanical modifications, resulting in changes in resistance to wood biodegrading agents. The objective of this study was to evaluate the resistance to biodeterioration of thermally modified wood by the industrial process VAP HolzSysteme® of Eucalyptus grandis, Pinus taeda and Tectona grandi

4. PHYSICAL AND MECHANICAL PROPERTIES OF PARTICLEBOARD FROM Eucalyptus grandis PRODUCED BY UREA FORMALDEHYDE RESIN WITH SiO2 NANOPARTICLES
ABSTRACT The use of nanoparticles appears to be a feasible option for improving the quality of a range of wood-based products. Studies show that they can improve both the physical and mechanical properties of wood and wood-based products. This preliminary study aimed to analyze the influence of SiO2 nanoparticles on the physical and mechanical properties of

5. STUDY OF THERMAL EXPANSION AND COMPRESSION STRENGTH OF THREE WOOD SPECIES FROM PLANTATIONS
ABSTRACT The objective of this study was to evaluate the effect generated by a thermal treatment on the dimensional changes and compression behavior of three wood species from commercial plantations (Eucalyptus nitens, Tectona grandis and Gmelina arborea). To accomplish the goal, dilatometric and compression tests were performed in the three directions of wo

7. PHYSICAL AND THERMAL PROPERTIES OF EUCALYPTUS WOOD CHARCOAL.
ABSTRACT The knowledge of the physical and thermal properties of eucalyptus charcoal is of fundamental importance in the design of equipment and development of cooling technologies. However, literature about physical properties for eucalyptus wood charcoal is largely unavailable, especially the thermal and aerodynamic properties, for the same material. The a

8. APPLICATIONS OF SAR DATA TO ESTIMATE FOREST BIOPHYSICAL VARIABLES IN BRAZIL
ABSTRACT The use of SAR images has been highlighted in scientific research focused on forest data collection worldwide. Thus, the present work aimed at gathering studies turned to the application of SAR images to obtain biophysical variables of forests in Brazil. Based on studies published in recognized databases, a growing amount of publications over time

9. DEVELOPING NEAR INFRARED SPECTROSCOPIC MODELS FOR PREDICTING DENSITY OF Eucalyptus WOOD BASED ON INDIRECT MEASUREMENT
ABSTRACT The objective of this study was to establish multivariate models for the prediction of wood basic density with reference to the values of average density of trees and near infrared (NIR) spectra measured in the breast height. The wood basic density of 39 Eucalyptus clones was determined in the laboratory by means of the mean longitudinal positions o

11. Modeling residual biomass from mechanized wood harvesting with data measured by forest harvester
Abstract: The lack of accurate models for estimating residual biomass in wood harvesting operations results in underutilization of this co-product by forestry companies. Due to the lack of this information, forestry operations planning, such as chipping and transport logistics, are influenced, with a consequent increase in costs. Thereby, the aim of this stu
