1. Effects of Frequency, Temperature and Test Duration in the Viscoelasticity of Brazilian Hardwoods Used in Handmade Musical Instruments
This study aims to make a comprehensive analysis on the viscoelastic behavior of typical tropical hardwoods and its influences in making musical instruments. For that a Dynamic-Mechanical Analysis was done and the mechanical parameters dependence on test control parameters like temperature, frequency and test duration time were measured. For Dalbergia Nigra

2. THERMAL PROFILE OF WOOD SPECIES FROM THE BRAZILIAN SEMI-ARID REGION SUBMITTED TO PYROLYSIS
ABSTRACT The objective of this study was to evaluate the thermal decomposition profile of 10 wood species from the semi-arid region of Brazil using thermogravimetric analysis (TGA) to investigate their potential as biomass energy sources. First, flash carbonization was carried out in a muffle furnace, in which wood samples were heated to a maximum temperatur

3. ESTIMATION OF THE CHARACTERISTIC VALUE OF WOOD STRENGTH
ABSTRACT For safety reasons, wood strength values, essential for structural dimensioning, are calculated based on the characteristic value, which corresponds to the 5% percentile of a given probability distribution model. For small samples, the Brazilian normative document ABNT NBR 7190 establishes an estimator of the characteristic wood strength, which can

9. Characterization of wood known in the Brazilian Amazon as mata-mata (Lecythidaceae fam. A. Rich.). / CaracterizaÃÃo das madeiras conhecidas na AmazÃnia Brasileira como MatÃ-matà (Lecythidaceae fam. A. Rich).
In spite of the great diversity of species of the Amazon forest, only a limited number of species is commercially exploited for wood production. This fact shows that the use of forest areas is only partial, with technical, economical and environmental disadvantageous consequences. A possible way to reduce this situation is the insertion of new species in the
