  1. 6. Climate change and urban drainage : future precipitation and hydraulic impact

    Författare :Mats Olofsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Sammanfattning : Increasing global mean temperature influences the hydrologic cycle. In the 21st century, hydrologic change featuring more heavy precipitation events is very likely according to the UN Intergovernmental Panel on Climate Change, IPCC. This change will have a great impact on urban environments and infrastructures. LÄS MER

  3. 7. Total knee arthroplasty : Alternative aspects on fixation, design and postoperative treatment

    Författare :Gunnar Adalberth; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Total knee arthroplasty; RSA; migration; all-polyethylene; drainage; cement; Kirurgi; Surgery; Kirurgi; Orthopaedics; ortopedi;

    Sammanfattning : Total knee arthroplasty as a treatment of severe gonarthrosis has become a great success, but tibial component loosening is still a major reason for failure. When total knee arthroplasty was introduced, only all-polyethylene (AP) tibial components were available. LÄS MER

  4. 8. Concrete slab on the ground and moisture control : verification of some methods to improve the moisture conditions in the foundation

    Författare :Lars-Erik Harderup; Avdelningen för Byggnadsfysik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Concrete slab; moisture; repair methods; ventilated foundation; drainage; numerical methods; grunder; grundplattor; platta på mark; betongplattor; fuktskador; reparationsmetoder; dränering; ventilerade konstruktioner; fukt; fukttransport; relativ fuktighet; temperatur; luftflöden; beräkningsmodeller; teori; fältundersökningar; mätresultat;

    Sammanfattning : This work deals with different types of repair methods for concrete slab on the ground damaged by moisture. Many of the available methods involve some kind of mechanical ventilation of the foundation. The basic principle for all these systems is the same. LÄS MER

  5. 9. Geographical Information Systems (GIS) as a tool for analysis and communications of multidimensional data

    Författare :Åke Sivertun; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Geographic Information Systems GIS ; Landscape Ecology; Artificial Drainage; Distributed Models; Environmental Change; Environmental Impact; Environmental Engineering; Landscape History; Drainage Technology; Historical Geography; Multidimensional and Multi-temporal Analysis; Hyperpixel; Colour Coding and Presentation of Multidimensional Data; Geografiska informationssystem;

    Sammanfattning : An integrating approach, including knowledge about whole systems of processes, is essential in order to reach both development and environmental protection goals. In this thesis Geographical Information Systems (GIS) are suggested as a tool to realise such integrated models. LÄS MER

  7. 10. Moisture Influence on Structural Behaviour of Pavements : Field and Laboratory Investigations

    Författare :Farhad Salour; Sigurdur Erlingsson; Guy Doré; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Falling Weight Deflectometer FWD ; backcalculation; unbound material; subgrade; seasonal variation; moisture content; spring-thaw; drainage; pavement stiffness; field test; pavement instrumentation; resilient modulus; permanent deformation; repeated load triaxial test; unsaturated soil; matric suction.; Civil and Architectural Engineering; Byggvetenskap; Transportvetenskap; Transport Science;

    Sammanfattning : The structural behaviour of pavements in cold regions can considerably be affected by seasonal variation in environmental factors such as temperature and moisture content. Along with the destructive effect of heavy traffic loads, climatic and environmental factors can considerably contribute to pavement deterioration. LÄS MER
