11. Ecology and genomics of microorganisms reducing the greenhouse gas N₂O : examples from the rhizosphere
Sammanfattning : Nitrous oxide (N₂O) is a potent greenhouse gas and the major ozone depleting substance in the stratosphere. One major source of N₂O is incomplete denitrification, whereas the only known tropospheric sink of N₂O is the microbial enzyme nitrous oxide reductase. LÄS MER
12. Agricultural land and landscapes : assessing the resource situation and developing an alternative system of agri-environmental payments : models with applications in Sweden
Sammanfattning : The agricultural land provision of private and public goods is studied by inter-disciplinary approaches on the supply from a resource economics perspective and on efficient policy measures from a welfare economic perspective. The socially optimal production of landscape public goods is derived theoretically by introducing the concept of quantitative hectares where measures of area and biodiversity etc. LÄS MER
13. Zeolite ZSM5 catalysts for abatement of nitrogen oxide
Sammanfattning : Airborne pollutants from the combustion of fossil fuels area global problem. Emission of nitrogen oxides (NOx) is increasing with the worldwide increase in theuse of energy. Atmospheric and photochemical reactions linknitrogen oxides to hydrocarbons and tropospheric ozone. LÄS MER
14. Nitrogen-containing products from atmospheric oxidation of volatile organic compounds
Sammanfattning : Atmospheric oxidation of volatile organic compounds (VOC) produces a wide range of oxygenated organic products that lead to formation of secondary organic aerosol (SOA). SOA represents a significant fraction of the tropospheric aerosol that influence climate and human health. LÄS MER
15. Is genetic diversity more important for terpene emissions than latitudinal adaptation? : Using genetically identical trees to better understand emission fluctuations across a European gradient
Sammanfattning : Biogenic volatile organic compounds (BVOCs) are trace gases other than CO2 and CH4 produced and emitted by the vegetation. The group consists of thousands of compounds in various shapes and sizes and with short atmospheric lifetimes. Some of the most common BVOC groups are called isoprene, monoterpenes and sesquiterpenes. LÄS MER
