Abstract
In 1997, FERIC, Alberta Research Council (ARC), Ainsworth Lumber Inc., and Daishowa-Marubeni International Ltd. conducted a study to determine the productivities and costs of various methods of managing logging debris in aspen cutblocks. Conventional roadside processing, two in-block processing treatments (intermediate skid and at-the-stump processing), and roadside processing with subsequent dispersal of slash into the block were assessed.

Abstract
Industrial heat treatment technology for wood has been under development since the 1970s. The technology consists in heating wood to temperatures of from 150°C to 240°C while preventing it from burning. This is achieved by heating the wood in either an inert atmosphere or saturated vapour environment. Heating the wood over 200°C changes the chemical structure of the wood and results in a reduction in its hydrophilic behaviour. After heat treatment when wood colour has changed to brown, an improvement in dimensional stability and biological durability should be observed. However, some mechanical properties of the wood may have decreased. This enhanced dimensional stability and biological durability make heat treatment an interesting option for the protection of wood used in exterior applications. The objectives of this study are to assess the performance of heat treatment technologies and to determine the properties of jack pine and balsam fir after heat treatment, as regards to exterior applications. Owing to difficulties in the start-up period that significantly delayed the project, no experimental work had been conducted by the end of March 2003. The lumber has however been sent to two companies for treatment and the physical and mechanical tests will be conducted under a new project entitled “Quality Control and Certification of Thermally Modified Wood.” A final report will be issued at the end of March 2004.

Abstract
With the appropriate mainline attachment, chain chokers are a viable alternative to conventional wire rope chokers, particularly for small-scale operations. This report provides users of tractor-mounted winches and cable skidders with technical information on chain chokers. The report covers type of steels, chain specifications and grades, and how to inspect chains for wear elongation. The various components (e.g. sliding hooks, rings) used to assemble chain chokers are also discussed.

Abstract
Avec un dispositif d'attache approprié au câble de traction principal, les colliers étrangleurs en chaîne peuvent remplacer efficacement les colliers étrangleurs traditionnels en câble d'acier, particulièrement dans des opérations à petite échelle. Le présent rapport fournit aux utilisateurs de treuils montés sur tracteur ainsi que de débardeurs à câble des renseignements techniques sur les colliers étrangleurs en chaîne. Le rapport couvre les types d'acier, les dimensions et les qualités de chaînes, et explique comment vérifier l'usure et l'allongement des chaînes. Il traite également des divers accessoires (crochets coulissants, anneaux) qui s'ajoutent aux chaînes pour constituer les colliers étrangleurs.
