  1. 6. Optimisation of Clinical Trials using Bayesian Decision Theory

    Författare :Sebastian Jobjörnsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; decision theory; drug regulation; ; Bayesian statistics; subgroup analysis; clinical trials; health economics; multiple testing; decision theory;

    Sammanfattning : A decision maker confronted with the task of designing a clinical trial has to consider a multitude of aspects. Large trials lead to more evidence,which in turn makes it less likely that harmful decisions are taken when deciding on future treatments for patients. LÄS MER

  3. 7. The Testatin/Cres subgroup of family 2 cystatins in sexual development

    Författare :Jessica Frygelius; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The genetic sex in mammals is established at fertilization, where an XX chromosome complement will lead to female development and an XY genotype will result in male development. Thereafter, sex determination is initiated with expression of the Y-linked factor Sry in XY gonads, leading to testis formation, while in the absence of Sry expression an ovary is formed. LÄS MER

  4. 8. Plasma cell malignancies in Sweden : subgroup descriptions and regional outcomes for multiple myeloma

    Författare :Göran Wålinder; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Plasma cell disorders appear in various forms such as aggressive plasma cell leukemia (PCL), typical symptomatic multiple myeloma (MM), non-symptomatic smouldering multiple myeloma (SMM) and solitary plasmacytoma (SP). The different entities all require specific considerations regarding diagnosis and treatment. LÄS MER

  5. 9. Holomorphic automorphisms of Danielewski surfaces

    Författare :Andreas Lind; Frank Kutzschebauch; Egmont Porten; Frank Wikström; Erik Low; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Danielewski surfaces; holomorphic; automorphisms; Lie groups; Algebra; geometry and mathematical analysis; Algebra; geometri och analys;

    Sammanfattning : In this thesis we define the notion of an overshear on a Danielewskisurface. Next we show that the group generated by the overshears is dense in the component of the identity of the automorphism group. LÄS MER

  7. 10. Models in chemistry education : A study of teaching and learning acids and bases in Swedish upper secondary schools

    Författare :Michal Drechsler; Jan van Driel; Helge Strömdahl; Ingo Eilks; Karlstads universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chemistry Education; Chemistry; Kemi; Chemistry; Kemi;

    Sammanfattning : This thesis reports an investigation of how acid-base models are taught and understood in Swedish upper secondary school. The definition of the concepts of acids and bases has evolved from a phenomenological level to an abstract (particle) level. Several models of acids and bases are introduced in Swedish secondary school. LÄS MER
