1. Retarded sorption in wood : experimental study, analyses and modeling
Abstract : Models of moisture flow processes in wood are normally based on a Fickian approach. In many instances, there are considerable discrepancies between modelling and experimental results. It is shown in this thesis that a major cause for these discrepancies is a so-called retarded sorption which is not accounted for in conventional theories. READ MORE

2. Studies of water vapor transport and sorption in wood
Abstract : This thesis deals with the evaluation of measurements of water vapor transport and sorption in wood. It mainly concerns measurements of the weight response of a sample after a step change in relative humidity. The thesis consists of an introduction and eight papers. The eight papers have the following contents: 1. READ MORE

3. Theoretical Investigation into Longitudinal Dispersion in Natural Rivers — A Scaling Dispersion Model
Abstract : Using a broad variety of scientific methods this dissertation systematically investigates the fundamental mechanisms underlying the dispersion processes in natural rivers and their mathematical descriptions in a geometrical framework. Emphasis is on the geometrical variations and irregularities of a natural river and their scales. READ MORE

4. Stochastic analysis of fluid flow and tracer pathways in crystalline fracture networks
Abstract : Understanding groundwater flow systems and how these control transport is an essential part in assessing the suitability of subsurface environments as hosts for storage of toxic waste. Therefore it is important to be able to integrate knowledge obtained from field characterisation of the subsurface with methods which can be used to evaluate and predict possible impact on surrounding environments.

5. Moisture transport processes in Scots pine - Anomalous capillary suction. Nonisothermal diffusion
Abstract : Moisture transport processes in wood have become increasingly important with the growing use of wood as construction material. This thesis deals with two key processes: capillary suction and nonisothermal diffusion. In the study on capillary suction, several methods were used. READ MORE
