    Sammanfattning : Introduction:Residents of low in-come countries have persistently suffered poor health outcomes, modest progress made over time notwithstanding. Weak health systems are one of the key reasons for the less than optimum progress. These health systems are constrained by inadequately equipped managers who play a main role in curbing this progress. LÄS MER

  4. 8. Upgrading concrete bridges : post-tensioning for higher loads

    Författare :Jonny Nilimaa; Mohammad Al-Emrani; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Concrete; Bridges; Upgrading; Strengthening; Shear; Field testing; Post-tensioning; Prestressing; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : There are a great number of old structures around the world, some of which were designed for completely different purposes than in their current application. Swedish railway bridges were for example only designed for maximum axle loads of 200 kN in the beginning of the 20th century, while the highest axle loads of today are twice as high. LÄS MER

  5. 9. I-girder Composite Bridges with Lateral Bracing : Improved load distribution

    Författare :Victor Vestman; Peter Collin; Robert Hällmark; Hans Petursson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; assessment; bridge; composite bridge; steel-concrete composite; I-girder; case study; horizontal trusses; lateral bracing; rehabilitation; strengthening; torsional stiffness; upgrading; Byggkonstruktion; Structural Engineering;

    Sammanfattning : This thesis deals with the subject of lateral bracing between the bottom flanges of I-girder composite bridges. The focus is on the impact of adding lateral bracing on existing bridges, as well as on new bridges. LÄS MER

  7. 10. Strengthening the pillars of cancer immunotherapy

    Författare :Maarten Alexander Ligtenberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The treatment of disease in cancer patients by harnessing the potent mechanisms that exist within the immune system is not a novel approach, and has been first attempted more than a century ago. During the major part of this century cancer immunotherapy has been relegated to the periphery of standard care for patients. LÄS MER
