16. Genetics of disease resistance in Norway spruce (Picea abies) : a look in the past with an eye to the future
Sammanfattning : Trees have evolved strategies to fight enemies and survive during their million-year history. These strategies have been shaped by natural selection and are reflected in their genomes today. Tree planting is a priority for governments, but there is a risk that trees selected by humans will lack alleles important for disease resistance. LÄS MER
17. The European forest trade model : EU policy and the impact on forest raw material use
Sammanfattning : The main purpose of this study is to develop a numerical simulation model of the European trade in forest fuels and analyse the possible trade levels for forest fuels in Europe following the implementation of EU energy policy. The White Paper and the RES-E Directive have been designed partly to support an increased use of forest fuels as sources for energy generation. LÄS MER

20. Studies to Avoid Decreased Efficiency in Multiple Stage Biological Wastewater Treatment Plants: Concerning Forests Industry Effluents
Sammanfattning : Målet med den här studien är att förhindra effektivitetssänkningar i moderna biologiska reningsanläggningar för skogsindustriella avloppsvatten. Biologiska processer är vanligtvis effektiva när det gäller att reducera lättnedbrytbart organiskt material. Eftersom den utgörs av levande mikroorganismer (MO) är tekniken känslig. LÄS MER
