  1. 6. Soil Modification by adding small amounts of binders : A laboratory study

    Författare :Wathiq Jasim Al-Jabban; Jan Laue; Sven Knutsson; Nadhir Al-Ansari; Paolo Simonini; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Sammanfattning : Soil stabilization through addition of a hydraulic binder is a method frequently used to modify and improve engineering properties of soft soils. Additives like cement and lime are typically used as stabilizers. More recently, industrial by-products, such as fly ashes, cement kiln dust, blast furnace slags and other slags have been used.

  3. 7. Mechanical anchorage of prestressed CFRP tendons : theory and tests

    Författare :Anders Bennitz; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : Fibre Reinforced Polymers (FRPs) are slowly becoming important materials to consider also for a structural engineer. They are light-weight, insensitive to corrosion and have highly modifiable mechanical properties. LÄS MER

  4. 8. Mineralogical influence on leaching behaviour of steelmaking slags : a laboratory investigation

    Författare :Fredrik Engström; Pekka Taskinen; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Sammanfattning : The Swedish steelmaking industry produces large amounts of by-products. In 2008, the total amount of slag produced reached approximately 1,300,000 metric tons, of which 20% was deposited. LÄS MER

  5. 9. Acetylcholine in Spinal Pain Modulation : An in vivo Study in the Rat

    Författare :Klas Abelson; Urban Höglund; Ernst Brodin; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Laboratory animals; Pain; Nociception; Antinociception; Acetylcholine; Muscarinic; Nicotinic; Spinal cord; Microdialysis; Försöksdjursvetenskap; Laboratory animal science; Försöksdjursvetenskap;

    Sammanfattning : The spinal cord is an important component in the processing and modulation of painful stimuli. Nerve signals from the periphery are relayed and further conducted to the brain (nociception) in the spinal cord, and the most essential modulation of painful information (antinociception) occurs here.

  7. 10. Hydraulic Conductivity of Saturated Sand-Bentonite mixtures

    Författare :Malin Sundsten; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quarry sand; design; bentonite; landfill barrier; field tests; dry density; foundry green sand; laboratory tests; hydraulic conductivity;

    Sammanfattning : The implementation of the EC directive concerning landfill liners and covers sets stricter technical and environmental requirements for landfill barriers. It is therefore essential to identify suitable materials that fulfil these requirements. LÄS MER
