  1. 1. Evaluation of protein and biological biomarkers in breast cancer

    Författare :Gustaf Rosin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Breast cancer is the most common malignancy in women around the world. There have been great improvements in treating the disease and today between 80-90% of the women survive at least 5-years after their primary diagnosis.

    Sammanfattning : Concurrent abuse of cocaine and alcohol is common among human addicts, where 85% of all cocaine users have also been shown to meet the criteria for alcohol dependence. Concurrent abuse of cocaine and alcohol is associated with a more severe dependence and a more pronounced abstinence than using either drug alone. LÄS MER

  4. 3. Resin acids in commercial products and the work environment of Swedish wood pellets production : Analytical methodology, occurrence and exposure

    Författare :Sara Axelsson; Ulrika Nilsson; Kåre Eriksson; Håkan Westberg; Martin Harper; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Rosin; resin acids; HPLC ESI-MS; air sampling; urine samples; wood pellets; wood dust; Analytical Chemistry; analytisk kemi;

    Sammanfattning : The aims of the work this thesis is based upon were to develop convenient analytical procedures for determining resin acids in biological and environmental matrices, and apply them to enhance understanding of the occurrence, exposure to and uptake by exposed individuals of resin acids. Particular focus has been on the workplace environment of the Swedish wood pellets industry. LÄS MER

  5. 4. Simulation of Combustion and Mixture Formation for Gasoline Direct Injection Engine Application

    Författare :Chen Huang; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VSB2; Reitz-KHRT; gasoline surrogate; LISA; sensitivity study.; Reitz-Diwakar; Trajectory collision; laminar flame speed; chemical kinetics; TAB; Rosin-Rammler; ignition delay; OpenFOAM; ethanol; O Rourke collision; SMD; hollow cone spray; liquid penetration;

    Sammanfattning : The development and introduction of new engine technologies are primarily motivated by the need to comply with increasingly stringent emissions legislation and to reduce fuel consumption. One of the most important of these new engine technologies is direct gasoline injection, which is considered to be an important and cost-effective measure to meet both targets. LÄS MER
