  1. 1. On Estimation of Moisture Content in Mass Impregnated Distribution Cables

    Detta är en avhandling från Stockholm : Elektrotekniska system

    Författare :Roberts Neimanis; KTH.; [2001]
    Nyckelord :;

    Sammanfattning : Mass impregnated paper insulated cables in distributionnetworks (6-33 kV) nowadays are gradually being replaced byXLPE insulated cables, yet, the percentage of mass impregnatedcables in distribution networks is still considerable. Thisreplacement is a long-term strategy, where right timing,properly made investments, etc. play crucial role. LÄS MER

    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Indoor environment; Questionnaire; Atopy; Building age; Indoor air quality; Sick building syndrome SBS ; Validation; Dwelling; Energy conservation; Mechanical ventilation; Building dampness; Building reconstruction; Wood heating; Electric heating; Heat pump; Thermal Insulation; Sealing; Medicin; MEDICINE Dermatology and venerology; clinical genetics; internal medicine; MEDICIN Dermatologi och venerologi; klinisk genetik; invärtesmedicin; arbets- och miljömedicin; Occupational and Environmental Medicine;

    Sammanfattning : The principal aim was to study selected aspects of indoor environment in dwellings and their association with symptoms compatible with the sick building syndrome (SBS). A validated questionnaire was developed specifically for residential indoor investigations, using sociological principles and test procedures. LÄS MER

  4. 4. Drip Sealing Grouting of Tunnels in Crystalline Rock: Conceptualisation and Technical Strategies

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Christian Butron; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; icicle formation; drip sealing; unsaturated flow; rock fracture; dripping.; channels; crystalline rock; design; Grouting; ice growth; evaluation;

    Sammanfattning : A conceptual model of the groundwater hydraulic conditions around the tunnel contour in ancient brittle crystalline rocks has been developed and verified. The general aim has been to reach an understanding of the groundwater conditions in and close to the tunnel roof where dripping takes place and to propose technical and practical strategies for waterproofing.
