  2. 1. Quantity and quality of soil organic matter in permafrost terrain

    Author : Gustaf Hugelius; Peter Kuhry; Philip Wookey; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; carbon; soil organic matter; soil organic carbon; permafrost; arctic; upscaling; peat plateau; cryoturbation; active layer; thermokarst; carbon nitrogen ratio; stable isotopes; humification; Physical geography; Naturgeografi; geografi med naturgeografisk inriktning; Physical Geography;

    Abstract : High latitude terrestrial ecosystems are considered key components in the global carbon (C) cycle and hold large reservoirs of soil organic carbon (SOC). Much of this is stored as soil organic matter (SOM) in permafrost soils and peat deposits and is vulnerable to remobilization under future global warming. READ MORE

  4. 2. Studies of physical activity in the Swedish population

    Author : Sven Johan Gustav Olsson; Mats Börjesson; Örjan Ekblom; Lena Kallings; Mikael Fogelholm; Gymnastik- och idrottshögskolan; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; physical activity; physical fitness; sedentary; questionnaire; validity; self-rated health; sensitivity; specificity; physical activity on prescription; accelerometry; the Ekblom-Bak test; answer modes; movement pattern; health-related quality of life; physical health; Medicin Teknik; Medicine Technology;

    Abstract : Background: Cheap and effective tools for measuring patients’ physical activity (PA) level are needed. The first aim in this thesis was therefore to assess the validity of two PA -questions, and their three associated answer modes, that are used within the Swedish health care system. READ MORE

  5. 3. Secondary absorbed dose distributions and radiation quality in light ion therapy

    Author : Martha Hultqvist; Irena Gudowska; Tatsuhiko Sato; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; secondary doses; light ion therapy; radiation quality; Monte Carlo simulation; Medical Radiation Physics; medicinsk strålningsfysik;

    Abstract : Radiotherapy with light ions offers the possibility of achieving a dose distribution which is highly conformed to the target volume while sparing normal tissues. For ions heavier than protons, an additional advantage is the increased Relative Biological Effectiveness (RBE) as compared to conventional photon and electron beams. READ MORE

  6. 4. Growth of high quality Fe thin films : A study of the effect of mismatch strain on the physical properties of Fe

    Author : Anna Lena Ravensburg; Vassilios Kapaklis; Björgvin Hjörvarsson; Tomas Kubart; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; thin film growth; crystal quality; strain; magnetism; electronic transport; Fysik; Physics;

    Abstract : The work in this licentiate is devoted to investigating the epitaxial growth of thin Fe layers on MgAl2O4 (001) and MgO (001) substrates using dc magnetron sputtering. The aim is to qualitatively and quantitatively determine the crystal quality of the grown Fe layers depending on their thickness, substrate material, and selected deposition parameters. READ MORE

  7. 5. Equity among children and youth with cerebral palsy : physical leisure activity, physical education, physiotherapy and quality of life

    Author : Frida Degerstedt; Martin Björklund; Birgit Enberg; Britt-Inger Keisu; Elisabet Rodby Bousquet; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Birth country; Cerebral palsy; equity; disability; gender; physical activity; physiotherapy; quality of life; physiotherapy; fysioterapi;

    Abstract : Background & aim: Cerebral palsy (CP) is the most common reason for movement difficulties among children and youth in Sweden. Physiotherapy is usually introduced early in order to develop mobility and prevent further impairment, which in turn facilitates activity and participation. READ MORE
