Abstract
Fourteen 1,220 by 2,440 by 11.1-mm commercial Oriented Strandboard (OSB) panels were X-ray scanned to obtain horizontal density matrices. Localized densities around the concentrated static load (CSL) testing points of the panels were calculated prior to the CSL test. A linear regression analysis was conducted to assess the impact of the localized density on CSL performance. The results indicated that both de ection and ultimate load were highly correlated with the local density. De ection and ultimate load were somewhat correlated (R2 ¼0.52). The CSL de ection decreased and ultimate load increased signi cantly with increasing local density. The impact of local density on ultimate load was greater than on de ection. Horizontal density variation is inherent in OSB manufacturing processes, especially in the mat forming process. A number of factors, including evenness of strands in the metering bin, condition of picker rolls and dissolving rolls, and strand and nes surging, can affect horizontal density distribution. OSB panels with a high degree of variation in horizontal panel density may cause low density spots that increase the chance of failure in CSL test. It is therefore crucial to minimize the occurrence of very low density areas in order to reduce the odds of ultimate load failure. Reducing density variability allows OSB companies to increase the CSL properties of their products, which would otherwise need to be done by making the panel denser. Improving horizontal density uniformity allows for lowering of the average panel density, which reduces the manufacturing cost and helps improve the company’s bottom line.

Abstract
The wood products industry is growing, as evidenced by the desire to build larger and taller buildings with timber and the start-up of new manufacturers. Despite the benefits of timber, projects are still experiencing approval resistance, namely when performance-based design (PBD), i.e., alternative solutions, are proposed to demonstrate code compliance. To gain approval, testing is often required to confirm the performance of a given product or design. While large-scale testing can always be performed, it tends to be very costly and time consuming, and can be argued to be valid only for the scenarios being tested. Fortunately, greater knowledge in fire safety engineering now allows for much more advanced/sophisticated fire modelling techniques. These techniques are gaining popularity in lieu of large-scale testing to extrapolate results and support PBD, provided the input parameters and results are verified and validated appropriately. This InfoNote summarizes some of FPInnovations activities related to advanced fire modeling in support of PBD.

Abstract
The use of snow fills as temporary crossing structures along winter roads is an accepted practice in B.C (Figure 1). In winter conditions where a small stream is likely to be frozen with no flow, log bundles are used with snow fill and, if correctly installed, can allow passage of seepage, or low flows, and reduce the volume of snow needed to fill the channel. Log bundles are an inexpensive option where logs and snow are easily available. Log bundles are not intended for use during periods of high flows or snow melt (freshet). Therefore, it is critical to remove log bundles and restore the natural stream channel before spring freshet while there is still road access. Poor results have been observed where log bundles were not removed before freshet

Abstract
Le séchage du bois est une étape critique du procédé de sciage. Un bon contrôle du procédé permet de maintenir une bonne qualité des produits, tout en assurant une bonne productivité et une consommation énergétique optimale, afin de garder les frais d’exploitation au minimum. Pour faciliter le travail des opérateurs de séchoir et des contremaîtres, ce contrôle peut s’accompagner d’un outil de simulation et d’optimisation du séchage. Celui-ci doit être flexible et prendre plusieurs paramètres en compte pour permettre la simulation de multiples situations. Outre l’optimisation du procédé, il permettrait de réduire la courbe d’apprentissage de nouveaux opérateurs, surtout dans un marché où la rétention de main-d’œuvre est difficile. Il serait aussi un outil idéal pour accélérer la numérisation de l’industrie.

Abstract
Dans le procede de sciage, la performance des scies circulates a un effet majeur sur le rendement en sciage et sur la qualite du produit fini. En vue de maintenir le rendement des scies a un niveau acceptable, les scies sont actuellement remplacees et affutees au moins une fois par quart de travail, ce qui exige un budget et un temps de main-d'oeuvre consequents. Les couts de production de I'usine peuvent ainsi etre reduits en ameliorant la duree de vie des scies et en diminuant les arrets non planifies. De plus, la variation de sciage diminuera si I'usure des aretes traitees est moins rapide de celles non traitees. L'objectif global du projet a ete le developpement d'une nouvelle generation de scies circulaires et de guides ultras performants. Pour atteindre cet objectif, FPInnovations, en collaboration avec I'Universite Laval et le Centre de metallurgie du Quebec, a travaille sur cinq axes de recherche : 1. Optimisation de la microstructure du substrat d'acier de la plaque de scie 2. Utilisation des lasers pour le traitement thermique et la modification de surface des gorges 3. Optimisation geometrique de I'arete tranchante des dents de scie et developpement d'un revetement PVD (depot physique en phase vapeur) par pulverisation cathodique 4. Amelioration de la resistance a I'usure et du coefficient de friction des guides par I'utilisation de lubrifiant solide 5. Ebauche de lames de scie multimateriaux

Abstract
La performance des scies circulaires a un effet majeur sur le rendement en sciage et sur la qualité du bois d’œuvre produit par les scieries. D’ailleurs, l’affûtage et le remplacement des scies à un rythme fréquent (une fois/quart de travail) ont une grande importance économique. En fournissant des scies plus performantes ayant des caractéristiques constantes, il serait possible de diminuer le rythme de remplacement des scies tout en améliorant la productivité et la qualité des sciages à travers la diminution de la variation de sciage et du temps d’arrêt non planifié. De plus, les coûts de production de l’usine peuvent être réduits en améliorant la durée de vie des scies, ce qui conduirait à son tour à réduire le nombre de nouvelles scies achetées. En collaboration avec différents partenaires industriels et manufacturiers, l’objectif principal de ce projet était le développement des prototypes de taille réelle de nouvelles générations de scies circulaires permettant des vitesses d’opération importantes pour des traits de scie d’environ 0,100 po. En vue d’atteindre cet objectif, cinq axes de recherche ont été développés

Abstract
Pathogen detection and identification have been vastly improved with advances in genomics; however, knowledge gaps remain around efficacy and use in wood commodities, especially in regulatory settings. In part one of this project, we compared detection efficacy of different methods on common export and import forest products. In-situ detection was more sensitive than traditional isolation, with 100% detection rates for some methods. However, there were several false positives in control samples. False positive detection of quarantine pathogens on wood products could be a serious problem in trade. The goal of part two of this project was to determine the cause of the false positives. In addition, we continued to compare detection methods by looking at point of care detection with a portable qPCR system and using RNA assays to test pathogen viability. False positives were likely due to DNA contamination persisting through the various wood processing steps. These results confirm the need for additional confirmation of pathogen presence or viability after a positive DNA test. RNA assays failed to detect pathogen presence in most samples. Further testing is needed to determine optimal RNA extraction conditions to provide meaningful results. Point of care detection using portable tools was comparable to laboratory methods and would provide a useful tool for pre-screening commodities for the presence of quarantine pathogens.

Abstract
A number of test series have been conducted at FPInnovations to evaluate the lateral resistance, fire resistance, and acoustic performance of the new Midply shear wall configuration. The results showed that the seismic force modification factors prescribed in the NBCC can be used, along with the enhanced lateral strength and stiffness. Moreover, with some minor design considerations, it was found that the new Midply with the resilient channels and insulation materials in both sides of the wall and both cavities can provide at least 1 hour of fire-resistance rating and provide at least an ASTC of 47.

Abstract
To improve the accessibility of genomics for the identification of wood inhabiting microorganisms to FPInnovations’ members, we compared three different methods for metabarcoding on environmental DNA (eDNA): cloning with first generation Sanger sequencing, amplicon metabarcoding with second generation Illumina sequencing, and lastly amplicon metabarcoding with third generation, long read sequencing with the portable MinION. We looked at costs for each method, speed, and difficulty. Illumina metabarcoding was the most economically feasible method. Cloning was difficult, being prone to failure and requiring extensive trouble shooting to complete. Illumina metabarcoding must be outsourced which can take more time for project completion; however, little in-house troubleshooting is necessary. Third generation sequencing is an attractive alternative for routine analysis. It is rapid, low-cost, and takes little up-front capital for start-up. However, it may not be feasible if used infrequently given the time required to learn the technology and the rapid expiration of unused flow cells. For occasional projects, it is recommended to outsource amplicon metabarcoding to a facility that sequences either with second or third generation sequencers, including data analysis.
