  1. 1. 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

It aimed at analyzing the issues and opportunities faced by the affected residents during regularization. LÄS MER

  5. 4. Structured Nanoporous Materials for Biogas Upgrading

    Författare :Kritika Narang Landström; Farid Akhtar; Andreas Kaiser; George Shimizu; Marta-Lena Antti; Manuel Moliner Marín; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanoporous materials; biogas upgrading; zeolites; metal-organic framework; carbon capture; separation kinetics; Materialteknik; Engineering Materials;

    Sammanfattning : Porous materials have shown potential for solving one of the significant challenges to sequestering CO2 gas from point sources. Microporous materials, zeolites and metal-organic frameworks (MOFs) are porous materials with tailorable adsorptive properties to develop higher performance for an energy-efficient CO2 separation.

  7. 5. Sustainable production of bio-energy products in the sawmill industry

    Författare :Anna Vidlund; KTH; []
    Nyckelord :sawmill industry; energy efficiency; heat recovery; integration; biofuel; upgrading; district heating; fuel pellets; CHP; VOC; CO2;

    Sammanfattning : One of the great challenges facing society is to convert theglobal energy system to a sustainable process. Currently, 80%of the world´s energy is supplied through the combustionof fossil fuels. Not only are the fossil resources limited, theutilisation also increases the level of greenhouse gases in theatmosphere. LÄS MER
