  1. 1. Qualitative analysis of a regional public policy for air quality : A case study of Normandie, France

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Arthur Avenas; [2021]
    Nyckelord :Atmospheric pollution; Atmosphere Protection Plan; policy planning; legislation; incentive measures; best practices; reduction of emissions; regional scale; case study; Normandie;

    Sammanfattning : Today, outdoor air quality occupies an important place into civic dialogue because of the many impacts of atmospheric pollution on health. Different legislations and strategies have thus been implemented across the world to improve outdoor air quality. LÄS MER

  2. 2. How design storms with normally distributed intensities customized from precipitation radar data in Sweden affect the modeled hydraulic response to extreme rainfalls

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära; Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Daniel Elfström; Max Stefansson; [2021]
    Nyckelord :cloudbursts; cloudburst mapping; spatial rain variation; pluvial flooding; hydraulic response; Swedish precipitation radar data; idealized urban catchment; hydrodynamic modeling; skyfall; skyfallskartering; gaussisk regnfördelning; spatial regnvariation; pluvial översvämning; hydraulisk respons; svensk nederbördsradardata; idealiserat urbant avrinningsområde; hydrodynamisk modellering;

    Sammanfattning : Intense but short-term cloudbursts may cause severe flooding in urban areas. Such short-term cloudbursts mostly are of convective character, where the rain intensity may vary considerably within relatively small areas. Using uniform design rains where maximum intensity is assumed over the whole catchment is common practice in Sweden, though. LÄS MER

  3. 3. Swedish Nitrogen Flows : A national budget of anthropogenically induced reactive nitrogen

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Vincent Lernbecher; [2021]
    Nyckelord :;

    Sammanfattning : Nitrogen is a fundamental element in all forms of life and a crucial component of our agricultural productivity and global food security. However, excess nitrogen caused by human activity poses a serious threat to the environment and human health. LÄS MER

  4. 4. Flambehandling som metod för ökad vätbarhet av polyolefina plaster

    Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Filiph Sandberg; [2021]
    Nyckelord :flambehandling; venturi;

    Sammanfattning : Liquid, pressurized natural gas in fiberglass tanks is becoming an increasingly common source of energy for the transport sector. The complete product consists of a plastic tank enclosed in fiberglass to achieve the required strength needed. LÄS MER

  5. 5. Hållbar konsumtion i Skåne

    Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Malin Nanhed; [2021]
    Nyckelord :global sustainability goals; negative; positive; interactions; sustainable consumption; sustainability goal 12; SDG 12; Agenda 2030; mapping tool; Sweden; Earth and Environmental Sciences;

    Sammanfattning : The pace of implementing the 17 global sustainability goals must increase drastically. The complexity of the goals is a challenge and mapping out interactions between them is identified as a way to explore their system properties and improve implementation. LÄS MER
