16. Anatomy, drying behaviour and mechanical properties of lesser used wood species from Mozambique
Abstract : The study provides an overview of Mozambique timber sector, descriptive and comparative wood anatomy, drying experiments and interrelationships between mechanics, density and anatomical features of lesser used species from Mozambique. Exhaustive literature review described the timber sector as dominated by few hardwood species selectively harvested from a forest containing 118 potential wood species. READ MORE

17. X-ray CT-scanning of wood during drying
Abstract : Moisture flux in wood during drying was studied using a medical CT scanner. A special device was built that enables performance of nondestructive measurements without removing the test piece during the whole drying process. READ MORE

18. Characterization of sawlogs using industrial X-ray and 3D scanning
Abstract : In the Nordic countries, sawlogs are typically sorted upon arrival at the sawmill based on species and dimension. By processing batches of logs with similar size, the sawing process becomes more efficient; the need to change sawing pattern between individual logs is reduced, and the handling of sawn goods is simplified, since the number of different dimensions produced simultaneously decreases.

19. Industrial Wood Drying : Airflow Distribution, Internal Heat Exchange and Moisture Content as Input and Feedback to the Process
Abstract : At a sawmill, the most energy demanding process is the wood drying. The drying process also has a great impact on quality parameters determined for the boards in the final sorting and thereby affects the sales value to a great extent. READ MORE

20. Characterisation of thermally modified wood for use as component in biobased building materials
Abstract : The building sector shows growing interest in biobased building materials. Wood components, here defined as ground or milled wood, i.e. by-products (residuals/residues) from wood processing, such as sawdust or shavings, are valuable raw materials for new types of durable biocomposites suitable for outdoor building applications.
