Abstract
An automated process has stringent tolerance requirements for product dimensions, such as maximum allowable wane and warping. Products that do not meet these tolerances create problems in the process flow, and hence reduce productivity and quality. In addition, the assembly of building components is moved from on site to off site. This move calls for the integration of different processes. It requires adjustments in raw material characteristics. Therefore, the forestry industry can gain from the opportunity to adapt its processes to provide dimensionally stable products to the construction industry.

Abstract
The remote and isolated communities of Northern Quebec, accessible only by boat or by air, use almost exclusively fuel oil to meet their energy needs. The heating systems of many community, institutional and commercial buildings have great potential for conversion to residual forest biomass. However, there is a supply challenge: how to provide a suitable feedstock for their equipment? And most importantly, in what form should it be shipped and stored to preserve its qualities?
Abstract
Les communautés éloignées et isolées du Nord-du-Québec, acces-sibles que par bateau ou par voie aérienne, utilisent presque exclusivement le mazout pour combler leurs besoins énergétiques. Les systèmes de chauffage de plusieurs bâtiments communautaires, institutionnels ou commerciaux présentent un fort potentiel pour la conversion à la biomasse forestière résiduelle. Toutefois, un défi d’approvisionnement se pose : comment fournir une matière première convenant à leur équipement? Et surtout, sous quelle forme l’expédier et l’entreposer pour conserver ses qualités ?

Abstract
A study conducted by FPInnovations in 60-year-old experimental white spruce plantations measured the long-term effects of initial plant spacing on tree volume yield, wood physical and mechanical characteristics the physical and mechanical characteristics of the wood, as well as the quality and value of the sawmill products. quality and value of the sawmill products, for spacing of 1.8 m, 2.7 m and 3.6 m.
Abstract
Une étude réalisée par FPInnovations dans des plantations expérimentales d’épinettes blanches de 60 ans a permis de mesurer les effets à long terme de l’espacement initial des plants sur le rendement en volume des arbres, sur les caractéristiques physiques et mécaniques du bois ainsi que sur la qualité et la valeur des produits du sciage, et ce, pour des espacements de 1,8 m, 2,7 m et 3,6 m.
