  1. 1. Biogeochemical data from SGU : properties and applications

    Författare :Kaj Lax; Reijo Salminen; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

    Sammanfattning : Geochemical mapping is a technique that has been used all over the world for a multitude of purposes. The biogeochemical mapping programme conducted by the Geological Survey of Sweden (SGU) is mainly based on stream plant chemistry, which, opposed to mapping based on inorganic stream sediments or soils, is a method that is very uncommon.

  5. 4. Searching for the optimal radiotherapy treatment time, dose and fractionation - the role of hypoxia and reoxygenation : A modelling study

    Författare :Emely Lindblom; Iuliana Toma-Dasu; Ingmar Lax; Ludvig Paul Muren; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hypoxia; Reoxygenation; SBRT; Fractionation; Medical Radiation Physics; medicinsk strålningsfysik;

    Sammanfattning : The search for the optimal choice of treatment time, dose and fractionation regimen is one of the major challenges in radiation therapy. Several aspects of the radiation response of tumours and normal tissues give different indications of how the parameters defining a fractionation schedule should be altered relative to each other which often results in contradictory conclusions.

  7. 5. Thiamin (vitamin B1) in the aquatic food web

    Författare :Emil Fridolfsson; Samuel Hylander; Michael T. Brett; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; phytoplankton; zooplankton; thiamin; transfer; food web dynamics; micronutrient; vitamin; Baltic Sea; community composition; M74; salmon; B1; växtplankton; djurplankton; tiamin; överföring; födoväv; mikronäringsämne; vitamin; Östersjön; B1; lax; Ecology; Ekologi;

    Sammanfattning : Thiamin (vitamin B1) is required for several life-sustaining processes in most organisms and cells, e.g. in the conversion of food to energy. It also serves as an antioxidant and is important for proper nerve signaling. LÄS MER
