1. Water resistance of Scots pine joints produced by linear friction welding
Abstract : Wood welding is a mechanical friction process allowing the assembly of timber without any adhesives. The process consists of applying mechanical friction, under pressure, alternately to the two wood surfaces to be welded. READ MORE

2. Micromechanical Modelling of Wood and Fibre Properties
Abstract : Wood is a material with mechanical properties that vary markedly, both within a tree and among trees. Moisture changes lead to shrinkage or swelling and modify the mechanical properties. READ MORE

3. Fine stream wood : effects on drift and brown trout (Salmo trutta) growth and behaviour
Abstract : Stream ecosystems and their riparian zones have previously been regarded as two different ecosystems, linked through numerous reciprocal subsidies. Today, ecologists agree that the stream and the riparian zone should be regarded as one system, the stream-riparian ecosystem, which is characterised largely by the subsidies between land and water.

4. Wood fibre deformation in combined shear and compression
Abstract : Mechanical pulping for producing pulps from softwood suitable for printing grade papers, like news, is a highly energy-intensive process consuming around 2000 kWh/t in electrical energy. Due to increasing energy costs and environmental issues there is a high demand for decreasing this energy consumption. READ MORE

5. Coated Norway Spruce : Influence of Wood Characteristics on Water Sorption and Coating Durability
Abstract : Wood used outdoors is often degraded and discoloured by microorganisms as a natural part of its life cycle, particularly when exposed to high levels of moisture for prolonged times. In this case, the application of a coating (i.e. paint) is an option for increasing the service life of the wood. READ MORE
