  2. 6. A Study of Different Methods for Inclusion Characterization towards On-line use during Steelmaking

    Author : Diana Janis; Pär Jönsson; Lauri Holappa; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; on-line method; PDA OES; electrolytic extraction; inclusions; clusters; nozzle clogging; secondary steelmaking;

    Abstract : The interest of gaining on-line information related to non-metallic inclusions during the steelmaking process has recently increased due to the development as well as the promising results of the Pulse Distribution Analysis with Optical Emission Spectroscopy method (PDA/OES). Even though, the time from sampling to presented results on inclusions is only about 5-10 minutes, the method has also shown limitations with respect to the determination of some inclusion characteristics.

  4. 7. On the physico-chemical properties of softwood hemicellulose and compounds derived from it

    Author : Polina Naidjonoka; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Hemicellulose is the second largest polysaccharide group available in nature after cellulose. Hemicellulose is present in plant cell walls along with cellulose and lignin. It is an abundant and biodegradable material that could potentially replace fossil-based products. READ MORE

  5. 8. Tyre aerodynamics of passenger vehicles

    Author : Erik Josefsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; drag; wind tunnel; tyres; aerodynamics; wheels;

    Abstract : To decelerate climate change and limit global warming, there is a need for reducing the environmental impact of vehicles, which can be achieved by increasing their energy efficiency. For a passenger vehicle, one of the largest resistive forces is aerodynamic drag. READ MORE

  6. 9. Socioeconomic inequalities in health : epidemiological studies of disease burden, mechanisms, and gender differences

    Author : Rickard Ljung; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Burden of disease; disability-adjusted life years; socioeconomic factors; gender; misclassification; myocardial infarction; life course; risk accumulation; risk clustering;

    Abstract : The overall aim of this thesis was to study inequalities in health, in particular, focusing on the risk of myocardial infarction and etiologic mechanisms from a life course perspective and on epidemiological measures and methodology. Paper I uses the Swedish Burden of Disease Study together with the Social Database managed by the Swedish National Board of Health and Welfare. READ MORE

  7. 10. Global-Scale Modelling of the Land-Surface Water Balance : Development and Analysis of WASMOD-M

    Author : Elin Widén-Nilsson; Sven Halldin; Chong-yu Xu; Lars-Christer Lundin; Jens Christian Refsgaard; Uppsala universitet; []
    Keywords : Hydrology; Global; Water balance; Runoff; Regionalisation; Model uncertainty; Multi-objective; Parameter; Evaluation criteria; Routing; Climate change; Hydrologi;

    Abstract : Water is essential for all life on earth. Global population increase and climate change are projected to increase the water stress, which already today is very high in many areas of the world. The differences between the largest and smallest global runoff estimates exceed the highest continental runoff estimates. READ MORE
