1. Treating depression and its comorbidity : From individualized Internet-delivered cognitive behavior therapy to affect-focused psychodynamic psychotherapy
Sammanfattning : The overarching goal of this thesis has been to enhance Internet-delivered psychological treatments for depression and its comorbidity. To this end, three randomized controlled trials (Study II, III and IV) with a total of 313 participants were conducted. LÄS MER
2. AIR CLASSIFICATION OF FINE AGGREGATES
Sammanfattning : Aggregates are defined as particles of rock which in combination are used as a civil engineering material. It is used in bounded form in asphalt and concrete. Historically natural sand has been used as fine aggregates for concrete production in Sweden. LÄS MER
3. Dry Classification of Fine Aggregates for Concrete and Asphalt
Sammanfattning : Aggregate is defined as particles of rock which in combination are used as a civil engineering material. It is used in bounded form in asphalt and concrete. Historically natural sand has been used as fine aggregate for concrete production in Sweden. LÄS MER
4. Metal Hydrogen Interaction and Structural Characterization of Amorphous Materials from first principles
Sammanfattning : In this thesis, first-principles calculations based on density functional theory have been employed to investigate metal hydrogen interaction in transition, p-block and rare earth metals. Furthermore, the accuracy of the stochastic quenching method was tested in describing the structure of amorphous Fe(1-x)Zrx. LÄS MER
5. Modelling elements in conversion of solid fuels - fixed bed combustion and gaseous radiation
Sammanfattning : For a long heat and power production by combustion of solid fuels has time been an established technique. Environmental concern of emissions for NOx, SOx and other harmful species has caused an increasingly stricter legislation on the emission levels of the boilers. LÄS MER
