  1. 1. Microstructure Formation and Mechanical Properties in Compacted Graphite Iron

    Författare :Mathias König; Ingvar L. Svensson; Magnus Wessén; Torsten Sjögren; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cast iron; CGI; Microstructure formation; Mechanical properties;

    Sammanfattning : Compacted graphite iron is rapidly becoming an attractive alternative for engine applications in the automotive industry. The improved process control now available that allows CGI components to be cast in a reproducible and reliable way has been the driving force for this development. LÄS MER

  4. 3. On the Microstructure and the Thermal Conductivity in Compacted Graphite Iron

    Författare :Martin Selin; Ingvar L. Svensson; Daniel Holmgren; Lars Nyborg; Kenneth Hamberg; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Compacted graphite iron; Microstructure; Thermal conductivity; Ferrite; Cementite; Nodularity; Mathematical modelling; Laser flash technique; Austempering;

    Sammanfattning : Compacted graphite iron (CGI) is a cast iron material that has gained much attention due to its attractive material properties which are intermediate between those of grey and ductile cast iron. In the automotive industry compacted graphite iron has become an interesting alternative material to grey cast iron in components like cylinder blocks or cylinder heads. LÄS MER

  7. 5. Family studies of schizophrenia and pregnancy outcomes

    Författare :Anna Svensson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Alternating logistic regression; environment; familial aggregation; fertility; generalized estimating equations; genes; obstetric complications; preterm birth; siblings; schizophrenia; small for gestational age; variance components;

    Sammanfattning : Why do psychiatric diseases run in families? Why do some women tend to have similar obstetric complications in subsequent pregnancies? The overall aim of this thesis was to investigate how genes and environments contribute to the aggregation of schizophrenia and adverse pregnancy outcomes in some families. Further, we also studied the fertility in families of patients with schizophrenia. LÄS MER
