    Sammanfattning : Large amounts of carbon disulphide are consumed in the conventional production of viscose. Until a novel, eco-friendly, wood-based process for the production of cellulose textile fibres has been developed and implemented, it is important to try to find ways to improve the conventional viscose process, e.g. LÄS MER

  4. 8. Essays on economic evaluation in health care : evaluation of hormone replacement therapy and uncertainty in economic evaluations

    Författare :Niklas Zethraeus; Handelshögskolan i Stockholm; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : This thesis contains six papers closely related to current research topics in the field of economic evaluation in health care. The thesis discusses methodological features of cost-effectiveness analysis (CEA) and cost-benefit analysis (CBA). It further relates to issues of modelling and how to account for uncertainty in economic evaluations. LÄS MER
