  1. 16. A Statistical Approach to Estimate Thermal Performance and Energy Renovation of Multifamily Buildings : Case study on a Swedish city district

    Författare :Martin Eriksson; Bahram Moshfegh; Shahnaz Amiri; Jan Akander; Sasan Sadrizadeh; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy signature; multifamily building; district heating; energy renovation; simulation; heat loss coefficient; balance temperature; base load; energisignatur; flerbostadshus; fjärrvärme; energirenovering; simulering; värmeförlustkoefficient; balanstemperatur; baslast; Hållbar stadsutveckling; Sustainable Urban Development;

    Sammanfattning : Several climate and energy goals have been set in the European Union, one of them being to increase energy efficiency. In Sweden, a large potential for increased energy efficiency lies in the residential and service sectors, which account for about 40% of total energy use. LÄS MER

  3. 17. Traumatic high-load injuries in the adolescent spine. Clinical, radiological and experimental studies

    Författare :Adad Baranto; Göteborgs universitet; []
    Nyckelord :Adolescence; athletes; spinal loading; back pain; disc degeneration; growth zone; intervertebral disc; MRI; nucleus pulposus; porcine spine; radiography; spine; vertebral endplate;

    Sammanfattning : Background: Disc degeneration and other radiological abnormalities are highly frequent among young athletes in sports with great demands on the back. It has also been reported that athletes with these abnormalities have more back pain than other athletes and non-athletes. LÄS MER

  4. 18. Condition assessment of concrete dams in cold climate

    Författare :Rikard Hellgren; Anders Ansell; Richard Malm; Anders Wiberg; Fernando Salazar González; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dam safety; dams; data analysis; monitoring; statistical models; hydraulic structures; static ice loads; concrete dams; cold regions; Betongbyggnad; Concrete Structures;

    Sammanfattning : Dams in many countries are approaching their expected service life. Proper assessment of the aging dams structural health increase the knowledge of the current safety, and allow for better planning of renovation and rebuilding investments. LÄS MER

  5. 19. Tracing environmental change and human impact as recorded in sediments from coastal areas of the northwestern Baltic Proper

    Författare :Lena Norbäck Ivarsson; Elinor Andrén; Thomas Andrén; Mikael Lönn; John Anderson; Södertörns högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; paleoecology; diatom stratigraphy; stable nitrogen isotopes; hypoxia; nutrient discharge; eutrophication; Medieval Climate Anomaly; Little Ice Age; Environmental Studies; Miljövetenskapliga studier; Östersjö- och Östeuropaforskning; Baltic and East European studies;

    Sammanfattning : The eutrophication of the Baltic Sea due to increased anthropogenic nutrient loads during the 20th century is well documented and studied. However, in the Baltic Sea drainage area, humans have affected the environment longer than the environmental monitoring can provide data for. LÄS MER

  7. 20. Experimental investigation of snow metamorphism at near-surface layers

    Författare :Lavan Kumar Eppanapelli; Mikael Sjödahl; Johan Casselgren; Arne Instanes; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Snow metamorphism; NIR reflectance; Snow and Ice; Radiative transfer equation; Paramterization; Snow properties; Tomography; Snow microstructure; Experimentell mekanik; Experimental Mechanics;

    Sammanfattning : Snow metamorphism is a direct objective in many snow research areas, and its charac-terisation is a major challenge in areas including winter road maintenance, detection of icing on wind turbine blades, and snow quality mapping for skiing. A common effect of snow metamorphism is compaction, which can be investigated from the associated vari-ations in physical properties of snow. LÄS MER
