1. Monoterpenes from the boreal coniferous forest : their role in atmospheric chemistry
Abstract : The goal of this work has been to increase our knowledge of the role of the monoteipenes emitted by the boreal coniferous forest in atmospheric chemical processes. To this end, measurements of air concentrations and emission rates have been made in forests of Scots pine (Pinus sylvestris) and Norwegian spruce (Picea abies) at 4 sites throughout Sweden, during the summers of 1989 and 1990.

2. Diffusion of large molecules in steam-exploded wood
Abstract : The diffusion of large molecules in wood pre-treated with steam explosion is important to understand in the context of the materials biorefinery. Steam explosion is a pretreatment method used to both open up the internal structure of wood and increase the accessibility of the cell walls of the wood with the use of high-pressure steam, and it is considered an energy-efficient method.

3. The Representation of Atmospheric Boundary Layer Processes in Global Climate Models
Abstract : The atmospheric boundary layer is the lowest part of the atmosphere, which is in direct contact with the surface. It is here, in this turbulent layer, that the exchange of heat, moisture and momentum between the surface and the atmosphere takes place. READ MORE

4. Biomedical and atmospheric applications of optical spectroscopy in scattering media
Abstract : Spectroscopic analysis of scattering media is difficult because the effective path length of the light is non-trivial to predict when photons are scattered many times. The main area of research for such conditions is biological tissues, which scatter light because of variations of the refractive index on the cellular level. READ MORE

5. On the Convective-Scale Predictability of the Atmosphere
Abstract : A well-represented description of convection in weather and climate models is essential since convective clouds strongly influence the climate system. Convective processes interact with radiation, redistribute sensible and latent heat and momentum, and impact hydrological processes through precipitation. READ MORE
