Characterisation of pellets made from oil palm residues in Costa Rica
(Journal of Oil Palm Research, 2016)
Presently, there are around 67 000 ha of oil palm (Elaeis guineensis) in Costa Rica. The resulting post-harvest residues are not being used currently. These residues can be employed for generation of heat by means of ...
Application of the X-ray densitometry in the evaluation of the quality and mechanical properties of biomass pellets
(Elsevier, 2015-04)
The use of the X-ray technique and the X-ray densitometry to determine pellet particle distribution and to understand the biomass compaction and its effects in pellet properties has been limited. The present work evaluates ...

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 thinning on diameter, heartwood, density and drying defects of gmelina arborea
(Universidade Federal de Sao Carlos, 2015)
The effect of three levels thinning intensity in Gmelina arborea plantation on tree diameter, heartwood (diameter and percentage), wood density and drying defects (twist, crook, bow and check) was studied. Wood used for ...
