    Författare :Jon Olofsson; Andreas Madestam; Björn Tyrefors; Marieke Bos; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Financial Economics; Development Economics; Banking; Innovation; Industrial Development; Political Economy; Police; Economics; nationalekonomi;

    Sammanfattning : The thesis consists of three self-contained essays.Local Banking and Historical Innovation: the Effect of Swedish Savings BanksHow does access to credit affect innovation at the early stages of development? This essay uses digitized records from the Swedish savings banks movement, in combination with novel data on the universe of historical patenting, to study how savings banks affected innovation in Sweden between 1900 and 1949, a period when the country was still a developing economy.

  4. 3. On wear transitions in the wheel-rail contact

    Författare :Sundh Jon; Ulf Olofsson; Staffan Jacobsson; KTH; []
    Nyckelord :Wear transitions; Wheel; Rail; Wear regime; Wear mechanism; Mechanical engineering; Maskinteknik;

    Sammanfattning : Wear transitions in the wheel–rail contact are of increasing interest since the general trend in railway traffic is toward increased velocities and axle loads. Curving increases the risk of flanging, causing the contact to change from an almost pure rolling wheel tread–rail head contact to more of a sliding wheel flange–rail gauge contact on the high rail in curves.

  5. 4. The role of herbivores in mediating responses of tundra ecosystems to climate change

    Författare :Elina Kaarlejärvi; Johan Olofsson; Anu Eskelinen; Jon Moen; Eric Post; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Climate change; warming; grazer; Rangifer; Lemmus lemmus; species distribution; biotic interactions; altitude; Environmental Science; miljövetenskap;

    Sammanfattning : The Arctic areas are warming more rapidly than other parts of the world. Increasing temperatures are predicted to result in shrubification, higher productivity, declining species diversity and new species invasions to the tundra. LÄS MER

  7. 5. Radon in Groundwater- Influencing Factors and Prediction Methodology for a Swedish Environment

    Författare :Kirlna Skeppström; Bo Olofsson; Per Erik Jansson; Jon Petter Gustafsson; Gerhard Barmen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Radon; Grondwater; GIS; RV method; Multivariate statistics; Water engineering; Vattenteknik;

    Sammanfattning : This thesis presents a method for predicting radon (222Rn) levels in groundwater on a general scale, within an area of approximately 185 x 145 km2. The method applies to Swedish conditions, where 222Rn is the main contributor to natural radioactivity. LÄS MER
