  1. 21. Biokolets påverkan på dagvattenkvaliteten i regnbäddar

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

    Author : Maja Hammarstedt; Wilma Insulander; [2023]
    Keywords : Biokol; dagvatten; regnbädd; vattenkvalitet; föroreningar; StormTac; dagvattenrening; näringsämnen; växtbädd; urban miljö;

    Abstract : Klimatförändringar och en större andel hårdgjorda ytor i städerna bidrar till en ökning av dagvatten som måste ledas bort. För att förhindra överbelastade VA-ledningar behöver dagvattnet fördröjas inom avrinningsområdet. En stor del av dagvattnet innehåller föroreningar från bland annat vägar, parker och industriområden.

  3. 22. Autophagy and senescence in primary human bronchial epithelial cells in the context of COPD

    University essay from Lunds universitet/Examensarbeten i molekylärbiologi

    Author : Annie Vegraeus; [2023]
    Keywords : Biology and Life Sciences;

    Abstract : Chronic obstructive pulmonary disease (COPD) is the third largest cause of death worldwide, with its most prominent risk factor being inhalation of smoke and pollutants. In this project, we studied two processes that are involved in COPD: autophagy and cellular senescence. READ MORE
