  2. 2. On the measurement and application of cement grout rheological properties

    Author : John Shamu; Stefan Larsson; Ulf Håkansson; Johan Funehag; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cement-based grouts; grouting; yield stress fluid YSF ; thixotropy; critical shear rate; radial flow; wall slip; Bingham model; Civil and Architectural Engineering; Byggvetenskap; Materials Science and Engineering; Teknisk materialvetenskap;

    Abstract : The rheological properties of cement-based grouts play a key role in determining the final spread in grouted rock formations. Rheologically, cement grouts are known to be complex thixotropic fluids, but their steady flow behavior is often described by fitting the simple Bingham constitutive law to flow curve data.

  3. 3. Rock grouting design: Rheological aspects and radial flow visualizations with ultrasound

    Author : John Shamu; Stefan Larsson; Ulf Håkansson; Liangchao Zou; Chadi El Mohtar; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cement grouts; grouting; yield stress fluid YSF ; thixotropy; critical shear rate; radial flow; wall slip; Bingham model; Cementbaserade injekteringsmedels; injektering; icke-Newtonska vätskors; tixotropi; kritisk deformationshastigheten; radiella strömning; glidning; Bingham modell; Jord- och bergmekanik; Soil and Rock Mechanics;

    Abstract : The rheological properties of cement-based grouts play a crucial role indetermining the final spread in grouted rock formations. In rheological terms,cement grouts are known to be complex time-dependent yield stress fluids,but their steady flow behavior is often described by the simple Binghamconstitutive law. READ MORE

  4. 4. SERVICE-ORIENTED ARCHITECTURE : AN INNOVATION PROCESS PERSPECTIVE

    Author : Annika Granebring; Péter Révay; Anita Håkansson; John Sören Pettersson; Mälardalens högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer and systems science; Data- och systemvetenskap; Industriell ekonomi och organisation;

    Abstract : In traditional information systems for the grocery retail trade, the different parts are strongly dependent of each other. Should one function change, the whole system must be rebuilt which is expensive and time consuming. The result is that many necessary process improvements are never done. READ MORE

  5. 5. Seeing the Word : John Dee and Renaissance Occultism

    Author : Håkan Håkansson; Avdelningen för idé- och lärdomshistoria; []
    Keywords : HUMANIORA; HUMANITIES; Philosophy; mysticism.; metaphors; symbolism; alchemy; magic; Renaissance philosophy; occultism; Filosofi;

    Abstract : This study reassesses the occult philosophy of the British polymath John Dee (1527-1609). Focusing on his treatise Monas hieroglyphica (1564) and his notorious angelic conversations in the 1580s, it describes Dee’s philosophical career as a continuous search for a language which could yield knowledge of both nature and God.
