Optical performance of finished and unfinished tropical timbers exposed to ultraviolet light in the field in Costa Rica
(Wood Material Science & Engineering, 2016)
This study evaluated wood color change (ΔE*) and the surface quality in 10 tropical wood species painted with three
finishes (composed of wax and polyurethane). Two weathering conditions were tested: natural weathering ...
Evaluation of chemical compositions, air-dry, preservation and workability of eight fastgrowing plantation species in Costa Rica
(Revista Madera y Bosques, 2015)
Costa Rica has successfully planted various forestry species for wood production. However, the use of their wood is limited, due to poor
knowledge about their chemical properties, air-dry, preserved and workability ...
Evaluation of wood properties from six native species of forest plantations in Costa Rica
(Bosque, 2016)
This study details information about physical, chemical and mechanical properties, drying, preservation and workability of wood
from Cordia alliodora, Dipteryx panamensis, Enterolobium cyclocarpum, Hieronyma alchorneoides, ...
Physical properties and fiber dimension in Stem, Branch and root of Alder Wood
(Parlar Scientific Publications, 2015-01)
The aim of this study was to determine physical properties and fiber dimensions in stem, branch and root wood for alder (Alnus glutinosa L) species. For this purpose, three normal alder trees were selected from Khanican ...
Effects of adding nano-clay (montmorillonite) on performance of polyvinyl acetate (PVAc) and urea-formaldehyde (UF) adhesives in Carapa guianensis, a tropical species
(Elsevier Ltd, 2015-06)
The aim of this study was to improve the bond strength resistance of polyvinyl acetate (PVAc) and urea-formaldehyde (UF) adhesives modified with nano-clay (montmorillonite) with a tropical species of wood known to exhibit ...
Biomass yield and energy potential of short-rotation energy plantations of Gmelina arborea one year old in Costa Rica
(Elsevier, 2016)
Short-rotation woody plantations have been recently established in Costa Rica and Gmelina arborea has
gained popularity The present work assesses tree diameter and height, biomass distribution, specific
gravity, green ...
Effects on density, shrinking, color changing and chemical surface analysis through FTIR of Tectona grandis thermo-treated: Density, shrinking, color changing and chemical analysis by FTIR of the thermally-treated teak wood
(Forest Sciences, 2016)
Thermal-treatment wood is used as an option to improve durability of wood in recent years. This study
evaluated the effect of temperature in thermally treated Tectona grandis wood in density, shrinking, color
changing ...
Biopulp from pineapple leaf fiber produced by colonization with two white-rot fungi: Trametes versicolor and Pleurotus ostreatus
(BioResources, 2016)
Trametes versicolor and Pleurotus ostreatus were used for the biopulping from pineapple leaf fiber (PALF). PALF substrate was subjected to T. versicolor for 2 to 6 weeks and to P. ostreatus for 4 to 8 weeks. The yields, ...
Reducing warp and checking in 4 by 4 beams from small-diameter tropical species (tectona grandis, gmelina arborea, and cordia alliodora) obtained by turning the pith inside out.
(Forest Products Society, 2015)
Small-diameter logs from plantation trees are prone to warp and to produce checks due to the presence of juvenile wood, growth stresses, and asymmetric shrinkage during the drying process. In the present study, we analyzed ...
Production and quality analysis of pellets manufactured from five potential energy crops in the Northern Region of Costa Rica
(Biomass and Bioenergy, 2016)
Modifications to a pellet manufacturing process must be made based on the characteristics of raw
material used. The purpose of this work was to determine the alternations required to a wood pellet
manufacturing process ...
