1. Natural Resistance of Seven Amazon Woods to Xylophagous Termite Nasutitermes octopilis (Banks)
ABSTRACT Some Amazonian woods are considered highly resistant to the attack of microorganisms; however, which ones present the highest resistance is unknown. This study aimed to evaluate the natural resistance of seven woods to xylophagous termite Nasutitermes octopilis through a no-choice feeding assay. The following wood species were assessed: Dinizia exc

2. Lumber Yield of Four Native Forest Species of the Amazon Region
ABSTRACT The objective of this study was to evaluate the volumetric lumber yield of four native species of the Amazon Region: Cedrinho (Erisma uncinatum Warm), Cumaru ( Dipteryx odorata Aublet), Garapeira (Apuleia leiocarpa Voguel), and Cambará (Qualea paraensis Ducke). Twelve logs of each species with different diameters were randomly selected from differ

7. Numerical simulation of the water movement and solutes in soil unsaturated / Simulação numérica do movimento de água e solutos em solos não saturados
The interest in studying problems of underground drainage and solutos transport not in soils saturated it has been increasing significantly in the last years, mainly because of the growing concern with the quality of the soil and of the environment in general. Applied fertilizers in agricultural lands move below the zone radicular of the plants and they can

8. Pequenos objetos de madeira de Eucalipto: Possibilidade de aproveitamento de resÃduo. / Small eucalipt wooden objects: possibility of waste utilization.
The mechanical processing of wood is an activity of the forest sector that generates enormous amounts of residues. It can be said that between 40 and 60% of the log volume are constituted by residues during its processing. In most of the cases, such waste are discarded at random or used as source of energy as a result of their combustion. This work had as ob

12. Tremorgenic mycotoxins from Aspergillus fumigatus as a possible occupational health problem in sawmills.
Wood-trimmers' disease, generally called extrinsic allergic alveolitis, which affects workers in sawmills, is thought to be caused by fungal diaspores. The importance of Aspergillus fumigatus on the surface of wood dried in kilns is accentuated by its ability to produce tremorgenic mycotoxins. Eight strains of A. fumigatus from five different sawmills were i
