    Sammanfattning : The mining of sulphidic ore to extract metals such as zinc and copper produces huge quantities of waste material. The weathering and oxidation of the waste produces what is commonly known as Acid Mine Drainage (AMD), a dilute sulphuric acid rich in Fe(II) and heavy metals. LÄS MER

  3. 3. Method Development for Characterisation of Superalloy used in Containment Design

    Författare :Ted Sjöberg; Mats Oldenburg; Jörgen Kajberg; Odd Geir Lademo; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : Due to the trend of increasing environmental demands put on civil aviation, manufacturersof commercial aircraft engines meet increased pressure to reduce weight. Modernturbofan engines represent up to almost one tenth of an aircraft's total weight, meaning areduction of engine component weight of just 30 kg is estimated to reduce CO2 emissionsby 400 tonnes over the lifetime of a medium sized commercial aircraft.

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; carborane; doxorubicin; 125I; molecular recognition; four-helix bundle; polypeptide conjugate; affinity; chitinase; acetylcholine esterase; Organisk kemi;

    Sammanfattning : This thesis describes the design and synthesis of molecules with potential roles in biomedicine, with an emphasis on molecular recognition in complex biological environments. The first chapter describes the synthesis and evaluation of compounds for use in nuclide therapy. LÄS MER
