Sammanfattning : The Vasa ship is not adequately supported. Measurements of the hull show that the ship deforms and rotate towards the port side. In addition, damages on the hull at support areas have been observed. The damages are due to high compressive loads. LÄS MER
2. Characterization, toxicity and treatment of wood leachate generated outdoors by the wood-based industryDetta är en avhandling från Växjö : Linnaeus University Press
Sammanfattning : 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. LÄS MER

- Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis
Sammanfattning : 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.
