1. Epiphytic lichen responses to nitrogen deposition
Abstract : Nitrogen (N) deposition has increased globally over the last 150 years and further increase is predicted for the future. Nitrogen is an important nutrient for lichens, involved in many processes in both photobiont and mycobiont. However, N can be a stressor, causing many lichens and lichen communities to disappear with increased deposition. READ MORE

2. Insights into the Molecular Mechanisms of Litter Decomposition and Assimilation of Nitrogen by Ectomycorrhizal Fungi
Abstract : Ectomycorrhizae is the dominant type of mycorrhiza found in association with tree roots in boreal and northern temperate forests. In this symbiosis, the fungal partner derives energy from photosynthates provided by the host trees and in return delivers soil-derived nutrients such as nitrogen (N). READ MORE

3. Secondary metabolites from the saprotrophic fungus Granulobasidium vellereum
Abstract : The production of secondary metabolites by the saprotrophic fungus Granulobasidium vellereum was investigated. G. vellereum is a wood decomposing basidiomycete fungus that arrives at dead trunks of fallen hard wood trees at a later stage of the decomposition process and hence need to outcompete the organisms already colonizing the site.

4. Carbonaceous Aerosol in Europe - out of the woods and into the blue?
Abstract : Particulate matter (PM) in the atmosphere influences weather and climate and may have important health impacts. Regional scale chemical transport modelling aims to describe the composition of particulate matter, to track different sources, estimate their relative importance, and to give realistic predictions of responses to changes in emissions and atmospheric conditions.

5. Application of Laser-based Diagnostics to a Prototype Gas Turbine Burner at Selected Pressures
Abstract : The matured laser-diagnostic techniques of planar laser-induced fluorescence (PLIF) and particle image velocimetry (PIV) were applied to a prototype gas turbine burner operating on various fuels. The work was performed to provide verification of computational fluid dynamic (CFD) models of the combustion of atypical fuels in a gas turbine combustor. READ MORE
