  1. 6. Long-term performance of water repellants on rendered autoclaved aerated concrete

    Författare :Hülya Kus; KTH; []
    Nyckelord :water repellants; renderings; autoclaved aerated concrete; surface treatments; long-term performance; degradation; natural weathering; artificial weathering; moisture monitoring;

    Sammanfattning : Many failures of external walls made of porous buildingmaterials are caused by excessive moisture content,particularly after driving rain and under long duration ofmoist conditions. Lack of sufficient protection againstexposure conditions is one of the reasons for external wallsprematurely demonstrating failures, i.e. LÄS MER

  3. 7. Degradation mechanisms and long-term performance of PUR insulation in district heating pipes

    Författare :Alberto Vega; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mechanical performance; thermal conductivity; District heating pipe; degradation mechanisms; long-term performance; rigid polyurethane foam;

    Sammanfattning : District heating networks are used worldwide, especially in Scandinavian countries and also in many other countries, e.g. Germany, Russia, United States, South Korea and China. From an environmental point of view, district heating networks are a good alternative to more traditional building heating systems. LÄS MER

  4. 8. Long term complications in juvenile diabetes mellitus

    Författare :Maria Nordwall; Johnny Ludvigsson; Knut Borch-Johnsen; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Diabetes mellitus type 1; diabetic retinopathy; diabetic nephropathy; diabetic neuropathy; epidemiology; C-peptide; Diabetology; Diabetologi;

    Sammanfattning : Background/aim. The incidence of microvascular complications has been reported to be unchanged the last decades. However, in randomized clinical trials it has been shown that improved metabolic control can reduce the development of long term complications. LÄS MER

  5. 9. Polymeric Outdoor Insulators - A Long-term Study

    Författare :Torbjörn Sörqvist; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The long-term performance and the material state of polymeric insulators were examined from December 1987 to February 1997. To a large extent the study was conducted at Anneberg field station, on the west coast of Sweden. The project comprised a great number of commercially available polymeric insulators from several prominent manufacturers. LÄS MER

  7. 10. Maternal smoking during pregnancy - Long-term health effects in the offspring

    Författare :Kristina Mattsson; Avdelningen för arbets- och miljömedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Maternal smoking during pregnancy; Medical Birth Register; long-term health effects; register validation; biomarker;

    Sammanfattning : Globally, around 10 % of women smoke during pregnancy today. It is known that pregnancy smoking increases the risk of adverse short-term health effects in the offspring, such as preterm birth, low birthweight and spontaneous abortion. Less is known about whether any adverse health effects persist until adulthood. LÄS MER
