1. Interfacial Properties of Biomacromolecular Model Systems: Surface Forces and Nanotribology
Abstract : The nanotribology, adhesion and related interfacial properties of biomacromolecular systems have been studied. The aim was to elucidate the role of physisorbed and chemically grafted bio-polymers implicated as mediators for cellulose based processing and material design. READ MORE

2. Three-Dimensional Load-Deformation Relationships of Arbitrarily Loaded Coiled Springs
Abstract : This paper reports the development of a computer based tool that can be used to predict the three-dimensional load-deformation relationships of arbitrarily loaded coiled springs. The non-linear deformation of the spring is calculated by dividing the spring into small elements for which the load-deformation relationships can be considered to be linear. READ MORE

3. Moisture-induced Distortion in Norway Spruce Timber - Experiments and Models
Abstract : Timber is a natural material that is environmentally friendly, renewable, light, strong and, in the eyes of most people, beautiful. Timber does, however, have one important drawback when it is used in a modern mechanised building process - its lack of straightness. READ MORE

4. Impact of cold climate on boreal ecosystem processes : exploring data and model uncertainties
Abstract : The impact of cold climate on physical and biological processes, especially the role of air and soil temperature in recovering photosynthesis and transpiration in boreal forests, was investigated in a series of studies. A process-based ecosystem model (CoupModel) considering atmospheric, soil and plant components was evaluated and developed using Generalized Likelihood Uncertainty Estimation (GLUE) and detailed measurements from three different sites.

5. Moisture-induced distortion in timber structures - examples based on partition walls
Abstract : The shape of timber changes due to variations in moisture content (MC). In Scandinavia, producers normally dry timber to an MC of 18%. However, after the studs are built into the wall structure, for example, they may become distorted as a result of further drying in the structure. The final MC in a heated building in Scandinavia is about 8%. READ MORE
