  1. 1. Filtration of Microcrystalline Cellulose: Electro-assisted filtration and the influence of surface properties

    Författare :Jonas Wetterling; Chalmers University of Technology; []
    Nyckelord :filtration; modelling; compressible filter cakes; electroosmotic dewatering; electrofiltration; local filtration properties; electro-assisted filtration; solid-liquid separation; dead-end filtration;

    Sammanfattning : One of the main requirements for the sustainable usage of materials is the use of renewable resources. This presents the Swedish forestry industry with the promising opportunity of using wood to produce not only traditional paper products but also a range of new materials of high value. LÄS MER

    Sammanfattning : High blood pressure (BP) is associated with cardiovascular morbidity and mortality. Both genetic and environmental factors are implicated in BP homeostatsis and hypertension development. LÄS MER

  5. 5. An Experimental Study to Measure And Improve the Grout Penetrability

    Författare :Ali Nejad Ghafar; Stefan Larsson; Almir Draganovic; Ulf Erik Lindblom; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Penetrability; Filtration; Erosion; Cement-based grout; Grout spread; Grout penetrability measurement; Dynamic grouting; Instantaneous variable pressure; Civil and Architectural Engineering; Byggvetenskap;

    Sammanfattning : An essential demand in any underground facility is to seal it against the water ingress to reduce the time and cost of the construction and the corresponding environmental hazards. To achieve this, obtaining sufficient grout spread is of great importance. LÄS MER
