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

    University dissertation from Stockholm : Karolinska Institutet, Dept of Clinical Science, Intervention and Technology

    Author : Leonard Clay; Karolinska Institutet.; Karolinska Institutet.; [2016]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : 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. READ MORE

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

    University dissertation from Luleå University of Technology

    Author : Ilda Tole; Andrzej Cwirzen; Mirja Illikainen; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; clay; sustainability; mechanical activation; ball milling; supplementary cementitious materials; alkali-activated materials; Byggmaterial; Building Materials;

    Abstract : 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.

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

    University dissertation from mediatryck, Lund University

    Author : Maria Jansson; [2019-04-12]
    Keywords : 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;

    Abstract : 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. READ MORE
