11. A study of slag-steel-inclusion interaction during Ladle treatment
Sammanfattning : The thesis is based on two supplements with two major objectives. In the first supplement equilibrium top slag-steel bulk and inclusions-steel bulk were investigated by comparison between calculated and measured oxygen activity values. This was done by applying different oxide activity models for slags combined with thermodynamic calculations. LÄS MER
12. Reducing Carbon Dioxide Emissions from the EU Power and Industry Sectors - An assessment of key technologies and measures
Sammanfattning : In February 2011, the European Council reconfirmed the goal of reducing EU greenhouse gas emissions by at least 80% by 2050, as compared to the levels in 1990. The power and industrial sectors currently account for almost half of the total GHG emissions in the EU. LÄS MER
13. Rational bioenergy utilisation in energy systems and impacts on CO2emissions
Sammanfattning : The increased concentration of greenhouse gases in theatmosphere, in particular CO2, is changing the Earths climate. Accordingto the Kyoto protocol, where the international community agreedon binding emission targets, developed countries are committedto reduce their greenhouse gas emissions. LÄS MER
14. Strength Properties of Paper produced from Softwood Kraft Pulp : Pulp Mixture, Reinforcement and Sheet Stratification
Sammanfattning : For paper producers, an understanding of the development of strength properties in the paper is of uttermost importance. Strong papers are important operators both in the traditional paper industry as well as in new fields of application, such as fibre-based packaging, furniture and light-weight building material.

15. Wood and fibre mechanics related to the thermomechanical pulping process
Sammanfattning : The main objective of this thesis was to improve the understanding of some aspects on wood and fibre mechanics related to conditions in the thermomechanical pulping process. Another objective was to measure the power distribution between the rotating plates in a refiner. LÄS MER
