  1. 6. Co-creating Solution Value: Understanding Process Dynamics and Digitization Effects

    Författare :Lei Huang; Handelshögskolan i Stockholm; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : Co-creating Solution Value“The only constant in life is change” – Heraclitus. Understanding changes in business is pivotal. How do changes occur and what are the consequences of changes? This thesis takes solution business as an empirical context and specifically inquires into the process of solution value co-creation, i.e. LÄS MER

  4. 8. The silicon nitride reaction-bonding process

    Författare :Bingqiang Lei; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material Mechanics; Materialmekanik;

    Sammanfattning : The so called Reaction-Bonded Silicon Nitride (RBSN) materials are usually produced through the chemical reaction of silicon powder compacts in a nitriding atmosphere. This nitriding reaction is strongly exothermic and much heat is generated, which may cause to overheating, even melting of the powder compacts so to hinder the further reaction due to the reduction of specific area of the powder compacts, especially when the nitridation involves a rather large mass of silicon.

  7. 10. Functional analysis of genetic variants in putative low penetrate breast cancer genes

    Författare :Haixin Lei; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Breast cancer; low penetrance gene; CDH1; ILC; IDC; mutation; SNP; BA CHI; ATM; EST1; cryptic splice site; SR proteins; dinucleotide repeats; splicing silencer.;

    Sammanfattning : Paper I & II: CDH1 germline mutations predispose individuals to diffuse gastric cancer, but its role in breast cancer is less clear. Somatic CDH1 mutations were reported to be frequent in lobular tumours (ILC), but they have not been found in ductal carcinomas (IDC). LÄS MER
