  1. 1. The evaluation, preoperative and operative aspects of abdominal wall reconstruction for giant ventral hernia

    Detta är en avhandling från Stockholm : Karolinska Institutet, Dept of Clinical Science, Intervention and Technology

    Författare :Leonard Clay; Karolinska Institutet.; Karolinska Institutet.; [2016]

    Sammanfattning : BACKGROUND: The optimal method for surgical repair of giant ventral hernia remains to be determined. Different concepts for reinforcement have been used, which have decreased the risk for recurrence. LÄS MER

  2. 2. Mechanical activation of clay a novel route to sustainable cementitious binders

    Detta är en avhandling från Luleå University of Technology

    Författare :Ilda Tole; Luleå tekniska universitet.; [2019]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; clay; sustainability; mechanical activation; ball milling; supplementary cementitious materials; alkali-activated materials; Byggmaterial; Building Materials;

    Sammanfattning : EU Sustainable Development Strategy planned to achieve improvement of life-quality by promoting sustainable production and consumption of raw materials. On November 2018, EU Commission presented a long-term strategy, aiming among others a climate-neutral economy by 2050. Cement production is contributing to 6-10% of the anthropogenic CO2 emissions.

  4. 4. Evaluation of the Tactoid Formation in Clay Systems

    Detta är en avhandling från mediatryck, Lund University

    Författare :Maria Jansson; [2019-04-12]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lera; Montmorillonit; Nano-plattor; Taktoider; Anisotropi; Grov korninga modeller; MD simuleringar; MC simuleringar; SAXS; Svälltryck; Clay; Montmorillonite; Nanoplatelets; Tactoid; Anisotropy; Coarse-grained models; MD simulations; MC simulations; SAXS; Swelling pressure;

    Sammanfattning : Clay minerals consist of anisotropic nanoplatelets where the majority of the clay minerals are highly charged, and thus, swell in aqueous solution. The structure and swelling depend on the type of clay mineral, and also on the ionic composition, and temperature. LÄS MER

  5. 5. Synthesis and applications of low silica zeolites from Bolivian clay and diatomaceous earth

    Detta är en avhandling från Luleå : Luleå University of Technology

    Författare :Javier Gustavo Garcia Mendoza; Luleå tekniska universitet.; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Zeolites; Synthesis; clay; diatomite; adsorption; ion exchange; Chemical Technology; Kemisk teknologi;

    Sammanfattning : The aim of the present work was to develop synthesis routes to produce synthetic zeolites with industrial attractiveness from non-expensive Bolivian raw materials, such as clays and diatomite. In particular, the work was focused on the synthesis of low-silica zeolites with the LTA and FAU structures. LÄS MER
