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

    Author : Leonard Clay; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    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

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

    Author : Ilda Tole; Andrzej Cwirzen; Mirja Illikainen; Luleå tekniska universitet; []

    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. 3. Spatial patterns in the interaction between Salix triandra and associated parasites

    Author : Lena Niemi; Anders Wennström; Lars Ericson; Keith Clay; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Gonioctena linnaeana; host-parasite interactions; leaf beetle; local adaptation; Melampsora amygdalinae; phenolics; pathogens; plant host; secondary chemistry; Terrestrial ecology; Terrestisk ekologi;

    Abstract : This thesis focuses on mechanisms and processes underlying spatial patterns of resistance and virulence and on local adaptations in plant–parasite interactions. The model system used comprises the plant host Salix triandra, the pathogenic rust fungus Melampsora amygdalinae, the leaf beetle Gonioctena linnaeana, and the galler Pontania triandrae. READ MORE

    Abstract : Clay minerals consist of clay platelets, which are anisotropic in both size and charge, and these can form a lamellar structure depending on the size, making it a seemingly perfect model system for an electrical double layer. The situation is however, from a structural point, slightly less ideal. READ MORE
