    University essay from SLU/Dept. of Urban and Rural Development

    Author : Theresé Engvall; [2022]
    Keywords : carbon; tree planting; communication; information; hegemony; invisibility cloak; post-colonial structures;

    Abstract : PES has become an important tool in climate mitigation policies, and has potential to increase the economic flow to low-income countries and enhance rural development. However, most studies show cases where policy design is in conflict with the local context. READ MORE

  3. 7. Determining the Reaction Mechanism of Hydrolysis of p-Nitrophenyl Butyrate Performed by a Cold-Adapted Lipase, BplA : Finding the Rate-Limiting Step

    University essay from Uppsala universitet/Beräkningsbiologi och bioinformatik

    Author : Linn Svalberg; [2021]
    Keywords : ;

    Abstract : Lipases are one of the most important biocatalysts for biotechnological applications. They have high importance since lipases have a catalytic activity that is related to their hydrolysis and synthesis reactions to high regioselectivity and enantioselectivity. They also have an activity over a wide range of temperature, pH, and diverse substrates. READ MORE
