Recommendations for the use of tree models to estimate national forest biomass and assess their uncertainty
(Springer-Verlag France, 2015-09)
Three options are proposed to improve the accuracy of national forest biomass estimates and decrease the uncertainty related to tree model selection depending on available data and national contexts. Introduction: Different ...
Pellets Evaluation Made from Tropical-Climate Agricultural and Forestry Crops of Costa Rica with a Domestic Stove
(Springer Netherlands, 2015-12)
The present study shows the results of the evaluation of the pellets made from two forestry crops and eight agricultural crops in Costa Rica by employing a 50 kW domestic stove. Methods: The following variables were ...
General, physical and mechanical properties, termites resistance and drying defects of lumber of Tectona grandis from plantations of different climatic and sites fertility condition
(Springer India, 2015-06)
The influence of climatic and site fertility conditions affect wood quality from fast growing trees. The change in tree diameter, thickness of sapwood, heartwood percentage and bark and pith tissue, physical and mechanical ...
Quality of pellets made from agricultural and forestry crops in costa rican tropical climates
(North Carolina State University, 2015)
Pellets may be produced with different types of agriculture or forestry crops in Costa Rica. This work evaluated the energy, physical, and mechanical properties of pellets fabricated from 12 types of agricultural and ...
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 ...
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 ...
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 ...
Evaluation of biodeterioration and the dynamic modulus of elasticity of wood in ten fast-growing tropical species in costa rica exposed to field testing
(Statny Drevarsky Vyskumny Ustav, 2015)
In tropical regions, it is possible to produce a large variety of timber species in plantation conditions. However, wood from these trees has low natural durability. Biodeterioration and the dynamic modulus of elasticity ...
Guidelines for documenting and reporting tree allometric equations
(Springer-Verlag France, 2015-09)
Given the pressing need to quantify carbon fluxes associated with terrestrial vegetation dynamics, an increasing number of researchers have sought to improve estimates of tree volume, biomass, and carbon stocks. Tree ...
