  3. 2. Application of data-driven models in exploring cyanobacterial bloom risks in Lake Mälaren

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Abigail Huertas Herrera; [2021]
    Keywords : Random Forest; blue-green algae; WHO Alert Level Framework; drinking water supply; cyanobacterial blooms;

    Abstract : Cyanobacteria are a unique organism, a bacterium that develop photosynthesis, thus it contains chlorophyll, a pigment commonly associated to algae. For this reason, cyanobacteria are also known as blue-green algae. One of the secondary metabolites of cyanobacteria is cyanotoxin, a substance which is hepatoxic, neurotoxic, and dermatoxic.

  4. 3. ManagementPractical Aspects of Aqua Ammonia as Secondary Refrigerant in Ice Rinks

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Jacqueline Pierri; [2021]
    Keywords : Ice rink; secondary refrigerant; refrigeration; refrigerant management; secondary fluid; natural refrigerant; aqua ammonia;

    Abstract : The transition from fluorinated gases to natural refrigerants could be key to reducing the impacts of climate change. Ice rinks are energy-intensive buildings, with large heating and cooling demands. The pumping power required to move the secondary refrigerant typically accounts for a sizable amount of the energy use of the refrigeration system. READ MORE
