Decomposition of Organic Chemical Components in Wood by Tropical Xylaria Species [PDF]

open access: yesJournal of Fungi, 2020
The ability of Xylaria species obtained from tropical wood and leaf litter to cause a mass loss of lignin and carbohydrates in wood was examined in vitro with pure culture decomposition tests.

Effect of Extractives on the Equilibrium Moisture Content and Shrinkage of Selected Tropical Wood Species

open access: yesBioResources, 2016
The main objective of this research was to investigate tropical wood sorptive properties. For selected tropical wood species (courbaril, ipe, light red meranti, merbau, tatajuba, and teak), the equilibrium moisture content was determined at 20 °C and 9 ...

Influence of the apparent density on the shrinkage of 43 tropical wood species [PDF]

open access: yesActa Scientiarum: Technology, 2019
Recently, more wood species are gaining space in market. Hence, it is important to enlarge the utilization of non-traditional woods, which shall be able to replace the most popular species, provided that similar performances are respected.

Chromophores' Contribution to Color Changes of Thermally Modified Tropical Wood Species. [PDF]

open access: yesPolymers (Basel), 2023
This work examines the effect of thermal modification temperature (180, 200, and 220 °C) in comparison with reference (untreated) samples on selected optical properties of six tropical wood species—Sp. cedar (Cedrala odorata), iroko (Chlorophora excelsa), merbau (Intsia spp.), meranti (Shorea spp.), padouk (Pterocarpus soyauxii), and teak (Tectona ...

Effect of fatigue on tropical wood species

open access: yesAmbiente Construído, 2022
Abstract The aim of present study was to create a theoretical model that allowed, with security and reliability, to obtain values of strength and stiffness to which the structural element will be submitted throughout its useful life. The effect was studied for strength and stiffness properties, and the modulus of elasticity (EM) and bending strength ...

Tropical Wood Species Recognition: A Dataset of Macroscopic Images

open access: yesData, 2022
Forests are of incalculable value due to the ecosystem services they provide to humanity such as carbon storage, climate regulation and participation in the hydrological cycle. The threat to forests grows as the population increases and the activities that are carried out in it, such as: cattle rearing, illegal trafficking, deforestation and harvesting.

Tension Wood and Opposite Wood in 21 Tropical Rain Forest Species [PDF]

open access: yesIAWA Journal, 2006
Wood samples were taken from the upper and lower sides of 21 naturally tilted trees from 18 families of angiosperms in the tropical rain forest in French Guyana. The measurement of growth stresses ensured that the two samples were taken from wood tissues in a different mechanical state: highly tensile stressed wood on the upper side, called tension ...

Bacterial and mold resistance of selected tropical wood species [PDF]

open access: yesBioResources, 2020
The biological resistance of 21 tropical wood species against bacteria and molds was studied. The gram-positive bacterium Staphylococcus aureus and the gram-negative bacterium Escherichia coli had none or negligible activity on surfaces of zebrano and maçaranduba (up to 1 ×106 CFU/mL), and they had negligible or medium activity on surfaces of macassar ...

Acoustic Properties of Selected Tropical Wood Species [PDF]

open access: yesJournal of Nondestructive Evaluation, 2010
Acoustic properties such as specific dynamic Young’s modulus (E′/γ), internal friction (Q −1) and acoustic conversion efficiency (ACE) of wood are important properties frequently examined by researchers. Vibration technique is one of the non-destructive evaluation techniques used as an alternative method for measuring the ...

Comparative wood anatomy of two tropical species

open access: yesScientia Agraria Paranaensis, 2020
Wood Anatomy is science field very relevant to understanding environmental climate changes and important in suggested to species conservation. The present study proposed the characterization of wood anatomy of Inga alba and Tapirira guianensis from two locations in the Legal Amazon, establishing ecological relationships between both and their habitat ...
