2. Characterization, toxicity and treatment of wood leachate generated outdoors by the wood-based industry
Abstract : Wood is a natural raw material, and would hardly be considered a risk to the environment. However, the handling of wood materials on an industrial scale has been shown to have a negative impact on water bodies that run-off from industrial sites that process wood-based materials. READ MORE

4. Static and time-dependent mechanical behaviour of preserved archaeological wood : Case studies of the seventeenth century warship Vasa
Abstract : Wooden objects have been widely used in the history of humanity and play an important role in our cultural heritage. The preservation of such objects is of great importance and can be a challenging task. This thesis investigates the static and time-dependent mechanical behaviour of archaeological oak wood from the Vasa warship. READ MORE

5. Implication of chemical deterioration on mechanical performance of wood
Abstract : The oak wood of the 17th century warship Vasa has shown significant changes in the chemical and mechanical properties as compared to recent oak. The most important factors contributing to these changes are the incorporation of iron compounds during waterlogging and the uptake of polyethylene glycol (PEG) in the course of the preservation treatment.
