  1. 11. Impact wave process modeling and optimization in high energy rate explosive welding

    Författare :Mohammad Tabatabaee Ghomi; Jafar Mahmoudi; Nils Erik Hannerz; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Explosive welding; Impact; Wave; Deformation; Velocity; Engineering mechanics; Teknisk mekanik; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : Impact waves are used in many different industries and are classified according to whether they cause plastic or elastic deformations. In the plastic deformation mode, these waves can be used to produce special electrical joints. In the elastic deformation mode, they can be used to detect leakage or to measure the thickness of pipes. LÄS MER

  3. 12. Health promotion and fall prevention for older people : impact, relevance and economic justification for decision making in a municipality context

    Författare :Saranda Bajraktari; Marlene Sandlund; Magnus Zingmark; Erik Rosendahl; Beatrice Pettersson; Erja Portegijs; Umeå universitet; []

    Sammanfattning : Background: The proportion of older people is increasing and calls for a shift towards proactive approaches to support healthy ageing. The evidence base on health-promoting and preventive interventions (HPP) is promising in terms of maintaining health in older people, but for such interventions to have an impact on population health, translation of evidence to practice is crucial.

  4. 13. Increasing the impact and sustainability of safe drinking water supply systems in rural Bangladesh : Randomized experiments with interventions in project life cycle

    Författare :Md. Ahasan Habib; Prosun Bhattacharya; Anna Tompsett; Mushfiq Mobarak; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Randomized Experiment; Safe Drinking Water; Participation; Decision-Making; Contribution Requirements; Cost-effectiveness; Faecal Coliform; Arsenic; Tubewell; Cleaning; Maintenance; Impact; Sustainability; Bangladesh; Randomiserat Experiment; Säkert Dricksvatten; Deltagande; Beslutsfattande; Bidragskrav; Kostnadseffektivitet; Fekal Koliform; Arsenik; Tubewell; Rengöring; Underhåll; Påverkan; Hållbarhet; Bangladesh; Mark- och vattenteknik; Land and Water Resources Engineering;

    Sammanfattning : Tillgång till rent dricksvatten är en global utmaning, vilket återspeglas i hållbar utvecklingsmål 6. I Bangladesh är det en brådskande fråga att överbrygga klyftan mellan de som har säkert hanterat dricksvatten och de med förbättrade källor. LÄS MER

  5. 14. Leave no trace: A non-destructive correlative approach providing new insights into impactites and meteorites

    Författare :Josefin Martell; Berggrundsgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; impact cratering; Mars; Mien impact structure; X-ray tomography; Neutron tomography; Shock metamorphism; Impact structure;

    Sammanfattning : Impact cratering is today recognized as a fundamental geological process on all rocky bodies in the solar system. On Earth, however, processes such as plate tectonics and erosion have eradicated most craters from the geological record, or they may be buried under sediments, oceans, and vegetation. LÄS MER

  7. 15. Biodiversity in environmental assessment : tools for impact prediction

    Författare :Mikael Gontier; Berit Balfors; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; Environmental impact assessment; Strategic environmental assessment; Biodiversity assessment; Prediction tools; GIS; GIS-base ecological models; Miljöteknik; Environmental engineering; Miljöteknik;

    Sammanfattning : Urbanisation and infrastructure developments impact on the surrounding natural environment and threaten biodiversity. The fragmentation of natural habitats in particular is a major obstacle for the preservation of biodiversity in a long-term perspective. LÄS MER
