  1. 1. Analysis of rock grouting with variable injection pressure

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Zhuohang Lian; [2022]
    Nyckelord :Rock engineering; Rock grouting; Variable injection pressure; Dynamic grouting technique;

    Sammanfattning : Rock grouting is an effective technique frequently used in rock engineering to reduce  groundwater ingress and increase the stability of surrounding rock mass. The real time grouting control (RTGC) is one of widely used  analytical models to predict the grouting process. LÄS MER

  3. 2. Experimental Evaluation of the Effects of Dynamic Pressure on Improving Cement-based Grout Penetrability : A study performed with the short slot

    Master-uppsats, KTH/Jord- och bergmekanik

    Författare :Anastasios Mentesidis; [2015]
    Nyckelord :penetrability; filtration; erosion; cement-based grout; variable dynamic grouting;

    Sammanfattning : The increasing need for watertight underground works, such as tunnel excavations, has sparked an interest in a number of research studies with grout penetrability being the focus. The research has so far contributed to a deeper understanding regarding the assessment of a successful grouting operation from different perspectives such as choice of equipment, material properties, phase planning and performance.

  4. 3. Antigena strukturer av betydelse för ett skyddande förvärvat immunsvar mot ekvint infektiöst anemivirus (EIAV) : Antigenic structures involved in development of protective acquired immunity against equine infectious anemia

    Kandidat-uppsats, SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Författare :Andrea Larsson; [2014]
    Nyckelord :ekvin infektiös anemi virus; förvärvat immunförsvar; cellmedierat immunförsvar; antikroppsamedierat immunförsvar; värd-virusdynamik; neutraliserande antikroppar; equine infectious anemia; acquired immunity; cellmediated immunresponse; humoral immunresponse; host-virus dynamics; neutralizing antibody;

    Sammanfattning : Denna litteraturstudie undersöker vilka immunogena strukturer som har betydelse för utveckling av ett skyddande förvärvat immunsvar mot ekvint infektiöst anemivirus (EIAV). Ekvin infektiös anemi (EIA) är en virussjukdom som drabbar hästdjur. LÄS MER
