  1. 1. Efficiency of the trackwork scheduling process in Sweden

    Författare :Daria Ivina; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railways; Maintenance management; Trackwork scheduling; Project Uncertainties; Lean; Efficiency;

    Sammanfattning : Efficient scheduling is vital for railway maintenance, which is increasingly challenged by rising train traffic and infrastructure wear. Trackwork often necessitates the reduction of train speeds and the partial or complete closure of tracks. LÄS MER

  3. 2. Intricacy and Stability of Graphene Spintronic Devices

    Författare :Daria Belotcerkovtceva; M. Venkata Kamalakar; Samuel Lara Avila; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Graphene, the first experimentally isolated atomically thin crystal has displayed numerous superlative properties for quantum and spin-based electronics, as evidenced by research results of more than a decade. The scalable form of graphene, produced by the chemical vapor deposition (CVD) method has been increasingly attracting scientific and technological interest, as outstanding properties are combined with large scalability and high quality.

  4. 3. The use of IGF-IR inhibitors in cancer therapy : a potential approach for sensitizing tumor cells to ionizing radiation

    Författare :Daria Cosaceanu; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : This study focused on insulin-like growth factor I receptor (IGF-IR), considered as a promising therapeutic target for cancer treatment. We were in particular interested in the involvement of IGF-IR in tumor cells response to radiation and we tried to provide the rationale for a combined therapy of IFG4R inhibitors with radiation in order to improve the therapeutic outcome.

  5. 4. Malaria, B lymphocytes and Epstein-Barr virus : emerging concepts on Burkitt's lymphoma pathogenesis

    Författare :Daria Donati; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Malaria; Plasmodium falciparum; B lymphocytes; polyclonal activation; hypergammaglobulenemia; EpsteinBarr virus; endemic Burkitt s lymphoma.;

    Sammanfattning : Plasmodium falciparum and Epstein-Barr virus (EBV) infections are recognized co-factors in the genesis of endemic Burkitt's Lymphoma (eBL), the most common paediatric cancer in equatorial Africa. This thesis work examines and discusses interactions between Pfalciparum and EBV that could promote the emergence of eBL. LÄS MER

  7. 5. Formation of small molecules in space through the process of radiative association

    Författare :Daria Jones; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; astrochemistry; reaction rate constants; formation of molecules; physical chemistry;

    Sammanfattning : This thesis is dedicated to calculating the reaction rate constants for the formation of molecules through radiative association (RA) under interstellar conditions. The molecules that have been studied are CH, AlCl, Na+ − H2 and Al+ − H2. LÄS MER
