    Abstract : Popular Abstract in Swedish Syftet med studierna som presenteras i denna avhandling har varit att undersöka om fordonsetanol kan framställas på ett lönsamt och energieffektivt sätt från restprodukter från jord- och skogsbruk enligt svenska förhållanden. Mycket av den forskning som rör andra-generationens etanolproduktion går ut på att förfina och förbättra de separata delstegen i framställningsprocessen. READ MORE

  2. 2. Investigating the parameters that influence the behaviour of natural iron ores during the iron production process

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Abraham Judah Bumalirivu Muwanguzi; KTH.; [2013]

    Abstract : This doctoral thesis analyses the role of historical urban agriculture in a long-time perspective, through a combination of overarching surveys of Swedish towns and detailed studies of one town – Uppsala in east-central Sweden. The study shows how agricultural land – town land – of various sizes was donated to towns repeatedly during medieval times and in the 16th and 17th centuries. READ MORE
