  1. 21. Studies of Volcanic Plumes with Remote Spectroscopic Sensing Techniques -DOAS and FTIR measurements on volcanoes of the Network for Observation of Volcanic and Atmospheric Change-

    Författare :Santiago Arellano; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; FTIR; Remote Sensing; DOAS; NOVAC; Volcanic gas emissions;

    Sammanfattning : Volcanism is a rich geodynamical process, closely linked to the origin and ongoing evolution of the lithosphere, atmosphere, hydrosphere and biosphere. Humans have benefited from the resources provided by volcanoes but also been threatened by the dangers of volcanic eruptions, which accurate prediction remains elusive. LÄS MER

    Sammanfattning : Nanocomposites of polyethylene and metal oxide nanoparticles have shown to be a feasible approachto the next generation of insulation in high voltage direct current cables. In order to reach an operationvoltage of 1 MV new insulation materials with reduced conductivity and increased breakdown strengthas compared to modern low-density polyethylene (LDPE) is needed.

  4. 23. The patient transfer task : methods for assessing work technique

    Författare :Christina Johnsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Experience; musculoskeletal problems; nurses; nursing students; observation methods; older people; patient transfer; training programme; work technique;

    Sammanfattning : The ability to move is an important part of everyday life. Assisted transfers, at hospitals or at home, can lead to high physical load on the nurse's musculoskeletal system, which in turn could cause musculoskeletal problems. LÄS MER

  5. 24. Learning from the behaviors and experiences of others

    Författare :Ida Selbing; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Learning to fear and avoid what is dangerous is crucial for survival. Perhaps equally important is the ability to learn that something which was previously dangerous is now safe. LÄS MER

  7. 25. Rapid tests for multidrug resistant tuberculosis in low income settings

    Författare :Freddie Bwanga; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Tuberculosis (TB) is at epidemic levels in the resource-limited settings (RLSs) due to HIV/AIDS, poverty and insufficient TB control programmes. These factors are also contributing to TB drug resistance. Patients with multidrug drug resistant tuberculosis (MDR-TB) do not respond to first line drugs. LÄS MER
